Description

The invention relates to a chop saw with the features of the preamble of claim 1. Such a chop saw is the EP 1 398 123 A2 refer to.

Cross-cut saws of the type in question have been known for decades ( EP-A-1 557 231 ). They are used to process all types of materials. A special field of application are chop saws in woodworking. But they can also be found for plastics processing and metalworking.

A typical chop saw has a saw unit mounted pivotably about a transverse axis, the saw blade of which is pivotable from a raised rest position into a lowered saw position and vice versa. With this movement of the saw blade, a workpiece located on a workpiece support surface of a support can be cut off - cut off -.

However, chop saws are known not only with a saw unit mounted pivotably about a transverse axis, but also with a saw unit which can be pulled over the workpiece support surface in the longitudinal direction as so-called radial saws.

The saw unit of a chop saw is normally biased in the direction of the rest position. This is usually done by a spring arrangement, in older constructions even by a counterweight. Contrary to the biasing force, the saw unit is handled on an operating handle and pivoted down to carry out the saw cut until the workpiece located on the workpiece support surface is completely severed. In this case, a small portion of the saw blade of the saw unit enters the edge in a submerged slot in the workpiece support surface.

( DE-U-203 13 885 discloses a miter saw, miter saw and miter saw with which miter cuts, miter cuts and shearing cuts (double miter cuts) can be made. Because of the also realized as a radial arm saw train function the cuts made are longer than the effective cutting radius of the saw blade dictates.

In the known chop saw the saw unit is mounted by means of a bracket on the carrier. When Kappfunktion the saw unit is pivoted about a transverse axis from the raised rest position in the lowered sawing position and vice versa.

On the holder, usually between the holder and the carrier, a tilt adjustment is provided here, moreover. The tilt adjustment is used to pivot the saw unit relative to the carrier to a horizontal axis of rotation extending in the sawing direction, just to perform a miter cut in the desired miter angle can. For this purpose, the tilt adjustment has a tilt swivel axis.

The tilt adjustment allows the saw unit to tilt laterally relative to the workpiece support surface so that corresponding miter cuts can be made with a bevel angle determined by the tilt adjustment. Typical bevel angles such as 45 ° or 30 °, besides the angle of ± 0 ° for the normal position, can be locked in position by means of bolts or levers which are operated by hand. But is often known only a stepless adjustment and fixation by means of a clamping screw with clamping knob. So is that also from the DE-U-203 13 885 known chop saw.

If a latching fixation of certain defined tilt positions is provided, then it is usually the case that the latching fixation takes place under spring load, while it can be released by manual handling, in particular the retraction of a spring-loaded bolt.

Since the tilt adjustment is located at the back of the workpiece support surface or the carrier, you have to be very attentive as an operator here. Normally, the manual handling to release the latching fixation is done with one hand behind the bracket, while the other hand of the operator holds the saw unit on the operating handle. The manual operation thus requires the use of both hands and several consecutive Handling steps. Since you have to reach the back of the saw unit or the holder, there is always a certain risk of injury.

In the known chop saw and a dust extraction on the saw unit is provided. This is located on the chop saw a suction. On this a suction hose or a dust bag of a dust catcher can be connected.

Also known from practice is another construction of a tilt adjustment in a chop saw such that at a fixed, preferably connected to the carrier part at least on one side of a stationary inclination stop is arranged. This is positioned so that it corresponds to a frequently used inclination angle of the saw unit. In particular, such a tilt stop is at 45 °. Associated with the inclination stop is arranged on the opposite part counter-attack. If the counter-stop is in contact with the tilt stop of the tilt adjustment, the saw unit is at the desired angle of inclination to the workpiece support surface.

In order to set the desired angle of inclination of the saw unit, ie in particular an angle of 45 °, which in practice arises most frequently, the inclination stop is designed as a screwed into a threaded bore, in particular in the carrier threaded pin. By screwing in or unscrewing the grub screw, the position of the inclination stop can be adjusted so that exactly 45 ° can be set as the inclination angle.

Occasionally there is also the desire to choose the miter angle a little larger than it corresponds to the geometric angle. This allows you to take into account tolerances, especially in interior design. For example, an angle of 47 ° as a miter angle instead of an angle of 45 ° allows less tolerance sensitive work in construction. The remaining small column can be filled with grouting material.

In a chop saw with the known from practice execution of the fixed inclination stopper as a set screw, the slightly larger angle of inclination can be by further screwing the threaded pin into the threaded hole realize. However, the adjustment of the exact inclination angle is lost.

Another chop saw is from the EP 1 570 963 A2 known, in which the holder of the saw unit can also be pivoted by means of a tilt adjustment relative to the carrier. In order to specify a certain miter angle by which the inclination adjustment can pivot the holder together with the saw unit and thus enable a miter cut, an angle limiting arrangement is provided. This comprises a metal tube, which opens with its one end in a teardrop-shaped metal plate, projecting from the pipe to the tube a threaded pin parallel to the tube. In the tube of the angle limiting arrangement, a rod which is rigidly connected to the carrier can be accommodated. At the other, free end of the tube an eruption is also provided.

The bracket also has for tilt adjustment a disc-shaped member having a central recess for receiving a pivot axis and a spaced therefrom arcuate outbreak through which the rigid rod of the carrier from one side and the plugged onto the rod tube of the angle limiting arrangement from the other side can extend. The arcuate breakthrough allows a rotational movement of the disc of the holder by a predetermined angle, wherein within the opening a threaded pin forms a counter-stop, which can be supported in a first position of the angle limiting mechanism on the outside of the tube as a contact surface or in a second position of the mechanism by the end recess on the pipe to the rod of the carrier comes to rest. By adjusting the angle limiting arrangement, a change in the angle of inclination can therefore be achieved by a value of + 3 °.

In order to fix the angle limiting arrangement in position, a handle with a clamping nut is provided in addition, which is in engagement with an external thread formed on the rigid rod of the carrier and the teardrop-shaped Plate of the angle limiting arrangement between them and a contact surface of the disc of the holder can frictionally clamp. The handling of a desired adjustment of the angle of inclination is therefore comparatively complicated. For this purpose, the user must first solve the frictional connection with the help of the handle by turning it and with this the inserted therein clamping nut. Only then can he access the mechanical arrangement of the inclination adjustment and pivot the teardrop-shaped plate of the angle limiting arrangement from its first position to a possible second position. Thereafter, he must again make the frictional fixation by turning the handle again, but this time in the opposite direction until the assembly is braced such that the angle limiting arrangement can no longer undesirably swing back to its first position.

The EP 1 632 323 A1 also discloses a chop saw with tilt adjustment, in which on a carrier associated with this fixed plate-shaped part is arranged, around which a tiltable with the saw unit and a holder of the saw unit is part. The stationary, plate-shaped carrier part has a stop arrangement with a pivotable stop. At the tilt swivel part of the holder, a counter-stop assembly is provided with a threaded pin, which can be supported in a first position of the stop member on this and in a second position of the stop member is guided past this.

With this arrangement, it is necessary for the user, in order to enable switching between two different angles of inclination, to pivot the abutment part of the abutment arrangement relative to the holder. In the figures, a screw is shown, which can optionally be solved or determined by means of a corresponding tool to pivot the stop member or to fix.

The EP 1 398 123 A2 shows finally a chop saw with a tilt adjustment, in which an arrangement for limiting the inclination angle is provided. These Arrangement comprises a limiter rod and three projections. The limiter bar is flattened in cross-section on two opposite sides, so that in the region of this flattening its outer diameter is smaller than at its remaining outer circumference. The rod is received in the housing of the pivotable holder and can be displaced therein along its longitudinal axis. With its free end, it extends into a recess of the carrier, in which the projections acting as stops are arranged. Depending on whether the attacks abut the flattened outer peripheral surface as a counter stop surface or on the remaining outer circumference of the rod as a counter stop surface, the inclination adjustment angle is greater or smaller by a few degrees. The Begrenzerstange may be provided at its end protruding from the holder with a Positonierer and be used by means of a handle against a spring tension in different recesses on the housing, which correspond to a predetermined angular position.

The teaching is based on the problem to optimize the known chop saw with the known from practice tilt adjustment application technology.

The above-indicated problem is solved in a chop saw with the features of the preamble of claim 1 by the features of the characterizing part of claim 1.

The core of the invention is the design of the tilt stop with two differently positioned stop surfaces. An abutment surface corresponds to the exact inclination angle of the saw unit. The second, slightly differently positioned stop surface leads to a slightly different, in particular slightly larger angle of inclination of the saw unit. Between the two stop surfaces you can switch the inclination stop. Are several stop surfaces provided, which would be possible in principle, so a total of stop surface to stop surface an adjustment is possible. It is important that the counter-stop always comes to rest on just one of the stop surfaces, so that the angle of inclination defined by the affected stop surface is realized on the saw unit.

By simply switching an adjustable component of the inclination stop, you can choose between the slightly different angles of inclination, without any adjustment is affected. This is handling technology practical and easy to use.

The construction according to the invention of a chop saw with inclination stop can be operated particularly simply by the design of the adjustable component as a complete turntable with a hand-action knob projecting outwards therefrom or the like. The turntable in this case has a resilient Verrastungselement which engages in each stage in a counter-element on the fixed part.

Preferred embodiments and further developments of the teaching according to the invention are the subject of the dependent claims.

In a first variant of the invention, both abutment surfaces are arranged on the adjustable, preferably stepwise adjustable component of the inclination stop. Then one and the same counter-attack hits once on one side, on the other side on the other. The adjustment of the component of the inclination stop leads to a switching of the stop surfaces.

In another variant of the invention, only one of the abutment surfaces is arranged on the adjustable component of the inclination stop. The other of the abutment surfaces is fixed to the associated part of the inclination adjustment, that is preferably arranged on the fixed part. Accordingly, the counter-attack is divided into two parts. In a position of the adjustable component of the inclination stopper hits a part of the counter-attack on the one stop surface. In the other position of the adjustable component of the inclination stop does not hit the said part of the counter-attack on the associated stop surface. Another part of the counter-attack hits the other, preferably fixed part of the tilt adjustment fixedly arranged stop surface.

As with the system known from practice, the inclination angles are also different here only by a few angular degrees, preferably by 1 ° to 5 °, in particular by 2 ° to 3 °. In particular, the same applies to the present chop saw, that such a tilt adjustment is realized in particular for inclination angle of 45 ° / 47 °.

A particular advantage of the construction according to the invention is that one can design a stop surface adjustable. In particular, this can also be done by a threaded pin which is screwed into a threaded hole and forms the relevant stop surface. The threaded hole does not have to be formed in the associated part itself, it can also be part of an inserted nut or a threaded neck. It is essential that you can realize the exact adjustment of the inclination angle, for example, 45 ° by means of the threaded pin and this adjustment is always maintained. The change to the slightly larger angle of inclination, for example, 47 ° is done without changing the position of the threaded pin and thus without changing the position of the corresponding stop surface. Rather, simply the adjustable component of the tilt stop is brought into the other position, so that the other stop surface acts.

The turntable according to the invention can be made in particular of plastic, as well as the manual operation knob, which serves to rotate the turntable. Carrying out the turntable in plastic, so it can be a latching element for locking in each stage particularly easy to implement as a molded spring clip.

Cross-cut saws of the type in question are known with one-sided and two-sided tilt adjustment. Accordingly, the construction can also be chosen here.

If a two-sided tilt adjustment realized, so you have at least two counter-attacks, so you can summarize the counter-attacks in a stop plate. In the stop plate and a counter-detent for a locking pin of a snap-in fixation can be integrated, which then expediently defines the normal position ± 0 °.

Fig. 1 shows a chop saw, more specifically a miter saw and miter saw.

In the Fig. 1 The chop saw shown initially has a carrier 1, which forms a workpiece support surface 2. The rear end of the workpiece support surface 2 here forms a stop rail 3, on which a workpiece, for example a wooden strip, can be applied. On the support 1, a holder 4 is mounted, which lies behind the back of the workpiece support surface 2.

Attached to the holder 4 above the carrier 1 is a saw unit 5. In the illustrated and preferred exemplary embodiment, this is pivotable about a transverse axis 6 and is located above the workpiece support surface 2.

With a radial arm saw, the transverse axis would be omitted. The saw unit would be pulled here on tie rods that cantilever over the workpiece support surface.

In the illustrated chop saw, the saw unit 5 is about the transverse axis 6 from a raised rest position, the in Fig. 1 can be seen in a lowered sawing, which is not shown here, and pivoted the other way round. The saw unit 5 is biased towards the rest position, ie upwards, in particular by a spring. As a result, the saw unit 5, when you let go, returns by itself back to the raised rest position.

• einen Antriebsmotor 8
• ein vom Antriebsmotor 8 angetriebenes, auf einer Welle 9 gelagertes Sägeblatt 10,
• eine das Sägeblatt 10 von oben her etwa über die Hälfte abdeckende feststehende Schutzhaube 11,
• eine Pendelschutzhaube 12, die in der in Fig. 1 dargestellten Ruhestellung den unteren Teil des Zahnkranzes des Sägeblattes 10 abdeckt,
• einen Absaugstutzen 13 einer Staubfangvorrichtung und
• eine im Bereich zwischen der Halterung 4 und der Welle 9 unterhalb der feststehenden Schutzhaube 11 angeordnete bewegliche Staubfanghaube 14.

The saw unit 5 indicates

• an operating handle 7,
• a drive motor 8
• a driven by the drive motor 8, mounted on a shaft 9 saw blade 10,
• a saw blade 10 from above about half covering the fixed protective hood 11,
• a swing guard 12, which in the in Fig. 1 shown rest position covers the lower part of the sprocket of the saw blade 10,
• a suction nozzle 13 a dust catching device and
• a movable dust collecting hood 14 arranged in the region between the holder 4 and the shaft 9 below the fixed protective hood 11.

The latter is a special feature of the chop saw, which does not always have to be realized, but is implemented in a particularly appropriate manner here.

The chop saw shown has a miter function in addition to the previously described Kappfunktion. So it's already a crosscut and miter saw.

For this purpose, the chop saw on the holder 4 in turn a tilt adjustment 15. With the tilt adjustment 15, the saw unit 5 can be compared to the carrier 1 to pivot about a direction of sawing, horizontal tilt pivot axis 16. Fig. 3 shows the tilt pivot axis 16 physically present. Basically, a backdrop-like design is possible in which the inclination pivot axis 16 is only geometrically present and the pivoting movement is realized about this virtual pivot axis via other means of construction.

At the tilt adjustment 15 can be seen in Fig. 1 an angle scale 17, at which one can read off the set angle of inclination. Due to the inclination about the inclination pivot axis 16, the miter angle of the executed saw cut can be adjusted and read off the angle scale 17.

However, the illustrated and preferred chop saw has not only a cap function and a miter function, it also has a traction function. The saw unit 5 is pivotally mounted on the holder 4 not only by means of the transverse axis 6, but additionally also by means of a running in the direction of sawing cable guide 18 of two mutually parallel drawbars 18a, b slidably mounted. With this train function can be extended by the saw unit 5 executable saw cut.

The illustrated and preferred embodiment shows on the support 1 a recessed turntable 19 with a forwardly projecting boom 20 and with a dipping slot 21 into which enters the sawing edge of the saw blade 10. The length of the immersion slit 21 is substantially greater than that required for the diameter of the saw blade 10. This is due to the previously described pull guide 18, which just allows pulling of the saw blade 10 through the workpiece over a certain path.

Fig. 2 shows in plan view here two mutually parallel tie rods 18a, b, which form the cable guide 18 and are rearwardly connected by a spacer 22 firmly together. The tie rods 18a, b are fixedly connected to the saw unit 5 and run on the holder 4 in Fig. 3 recognizable guides 23.

In a Radialarmsäge, which has no Kappfunktion, only a traction function and possibly a miter function, a kinematic reverse arrangement with fixed tie rods and slidably guided by means of guides sawing unit is possible.

The above statements relate to the illustrated miter, miter and tension saw in general. The invention concerned in the present application will be described below.

In the illustrated and preferred embodiment, a very particular tilt adjustment 15 is realized about a tilt pivot axis 16. This is based on the drawing, 4 to 6 , explained in more detail. Fig. 4 and Fig. 5 are shortened to the left and right to enlarge the scale.

The inclination adjustment 15 has a fixed part 24 connected to the carrier 1 and a tilt-pivotable part 25 connected to the saw unit 5, more precisely to the holder 4 of the saw unit 5 (FIG. Fig. 3 ). The latter is in Fig. 4 and 5 not visible, because the holder 4 is removed.

On one of the parts, in the illustrated and preferred embodiment on the fixed part 24, a stationary inclination stop 29 is arranged at least on one side, which corresponds to a frequently used inclination angle of the saw unit 5.

Fig. 4 shows the back of the carrier 1 with the fixed part 24 in a view, wherein the holder 4 is removed with the saw unit 5. In detail, this will be explained below.

In Fig. 4 can be seen first a large clamping lever 24 'for non-positive connection of the tilt-pivoting member 25 with the fixed part 24, here and according to preferred teaching on a clamping of the tilt pivot axis 16. This is a component of the here also realized stepless tilt adjustment.

Furthermore, in Fig. 4 to recognize that a latching fixing a certain inclination of the saw unit 5 is provided here. The normal position with an inclination angle ± 0 ° is in fact fixed in place by a latching pin 26, which can be actuated manually by means of a latching actuating lever 27. In the illustrated embodiment, this locking pin 26 is engaged in a mating catch 28, which, which will be explained later, the tiltable part 25 is assigned.

In order to better understand the relationships in the construction according to the invention, the part 36, which is arranged on the tilt-pivotable part 25 per se, but for the inventive tilt adjustment 15 constructively important in Fig. 4 located.

According to the invention, it is neither the stepless, clamping inclination adjustment nor the latching fixation certain inclination angle. Rather, the illustrated and preferred embodiment shows a definition of a certain angle of inclination by the stationary inclination stop 29. Stationary in this sense means that the inclination stop 29 is arranged as such on the carrier 1 in fixed relative position to the carrier 1. In contrast, a counter-stop 30 with the inclination-pivoting part 25 is pivotable relative to the fixed part 24 of the carrier 1 and thus relative to the inclination stop 29 about the inclination pivot axis 16.

The position of the inclination stop 29 corresponds to a frequently used inclination angle. In the illustrated embodiment, this is the inclination angle of 45 °.

As already mentioned, the counterpart stop 30 is fixedly arranged on the other side of the parts 24, 25, in this case on the tilt-pivotable part 25. When concerns of the counter-stop 30 on the slope stop 29 of the tilt adjustment 15 is the saw unit 5 at the desired angle of inclination, in this case the inclination angle of 45 ° to the workpiece support surface. 2

It is essential for the invention that the inclination stop 29 has at least two slightly differently positioned abutment surfaces 29 a, b whose positions define slightly different inclination angles of the saw unit 5.

In order to activate the stop surface 29a, 29b which is of interest in each case, it is provided that the inclination stop 29 has a component 32 which is mounted so as to be adjustable in steps such that the counter stop 30 always comes into contact with only one of the stop surfaces 29a, b.

This in Fig. 4 illustrated embodiment shows a construction in which both stop surfaces 29a, b are arranged on the stepwise adjustable component 32 of the inclination stop. The counter-stop acts in one position of the component 32 with the one stop surface 29a together, in Fig. 4 shown on the left. In the other position of the component 32 of the counter-stop 30 cooperates with the other stop surface 29 b, in Fig. 4 shown on the right.

The in Fig. 4 Inclined stop 29 on the left defines the position 45 ° of the abutment surface 29a. The in Fig. 4 Inclined stop 29 shown on the right has a different position in which the saw unit 5 is at an angle of 47 °, when the counter-stop 30 comes to rest on the stop surface 29b.

This in Fig. 4 illustrated embodiment shows a construction in which an inclination stop 29 is disposed on both sides, each of which a counter-stop 30 is assigned. It is therefore a two-sided tilt adjustment 15.

The illustrated and preferred embodiment also shows that the two counter-stops 30 are summarized here together with the mating catch 28 of the locking bolt 26 for ± 0 ° in a metal stop plate 36 which pivot on the tilt Part 25 attached, in particular screwed. You can see them in Fig. 4 just to facilitate understanding.

The illustrated embodiment shows that the defined by the two abutment surfaces 29a, b angle of inclination differ by a few degrees, preferably by 1 ° to 5 °, in particular by 2 ° to 3 °. In detail, it applies here that the stop surfaces 29a, b define the angle of inclination of the saw unit 5 of 45 ° and 47 °.

This in Fig. 5 illustrated embodiment, the representation corresponds largely Fig. 4 , unlike at Fig. 4 a stop surface 29a on the adjustable component 32 of the inclination stop 29, the other stop surface 29b but stationary on the fixed part 24. Here, the counter-stop 30 has a second part, namely the part 30 '. The part 30 'cooperates with the second stop surface 29b. Is the stepwise adjustable component 32 of the inclination stop 29 in the in Fig. 5 shown on the right, so the part 30 'of the counter-stop 30 hits the stationary stop surface 29b. The other part of the counter-stop 30, however, does not touch the component 32. In contrast, meets in the other position of the component 32 of the counter-stop 30 as in the embodiment Fig. 4 on the stop surface 29a, as in Fig. 5 shown on the left. Here then the stop surface 29b and the part 30 'of the counter-stop 30 are ineffective.

The illustrated and preferred embodiment also shows that at least one stop surface 29a is adjustable, in particular by a threaded pin 31 which forms the stop surface 29a. One recognizes this construction better in the representation in Fig. 6 , The threaded pin 31 is screwed into the threaded bore of an associated, inserted into a holder on the inclination stop 29 threaded nut 37. By adjusting the threaded pin 31, the position of the stop surface 29a can be adjusted. As a result, the main, precise inclination angle of 45 ° of the illustrated embodiment can be adjusted exactly. This adjustment is not lost because the set screw 31 no longer needs to be adjusted. The desired slightly different angle of inclination of 47 ° in this case is achieved according to the invention in that the component 32 can be adjusted in total to the other stage.

The embodiment shown in the drawings shows a construction in which it is provided that the inclination stop 29 as an adjustable component has a compact turntable 32 with a projecting from the hub 32 to the outside of the hand operation knob 33.

Fig. 6 shows the turntable 32 preferably made of injection-moldable plastic. Directly molded is the manual operation knob 33, which protrudes radially outward. At the turntable 32 is a resilient Verrastungselement 34. This engages in each stage in a counter-element 35 on the associated fixed part 24 a.

In the illustrated embodiment with a plastic hub 32 is the latching element 34 is formed on the hub 32 spring clip.

One recognizes in Fig. 6 the threaded nut 37, which is inserted into a receiving compartment in the hub 32. From above, the threaded pin 31 is screwed in and adjusted exactly to the desired tilt position of the saw unit 5. This component 32 is how to in Fig. 4 and 5 sees, used in a holder 38 which is formed on the most executed as a metal die casting fixed part 24 on the carrier 1. On the holder 38, the counter-elements 35 can be seen for the engagement of the resilient latching element 34. The latching element 34 of in Fig. 4 and 5 shown left component 32 is engaged in the lower counter-element 35 (set angle 45 °, adjusted). The in Fig. 4 Inclined stop 29 shown on the right shows the component 32 with the latching element 34 locked in the upper counter-element 35 of the holder 38 (set inclination angle 47 °, not adjusted). In Fig. 5 On the contrary, on the right, the part 30 'cooperates with the abutment surface 29b on the fixed part 24 in order to define the inclination angle 47 °, not adjusted.
