Description

Field of application of the invention

The invention relates to a device for removing and removing workpieces with pivotable abutment axis and material stop for cutting workpieces, and equipped with pneumatically controlled Werkstückabnehmerträger automatic lathe.

Characteristic of the known technical solutions

In a known device of this type, for removing and removing workpieces, carries the Werkstückabnehmerträger a customer cartridge on which a clamping part, consisting of holder, ball and compression spring plugged and clamped. In this case, the takeaway lemon has a circular opening in the wall, which is slightly smaller in diameter than the ball diameter and countersunk from the outside. The clamping part is arranged on the customer cartridge, that the spring-loaded ball sits in the opening and projects slightly into the bore. The bore of the customer cartridge depends on the workpiece diameter to be removed, the projection of the ball into the hole is constant. The customer cartridge is slid onto the material shortly before the workpiece is cut. If the workpiece is separated from the material, it is pressed under the pressure of the ball against the inner wall of the customer cartridge and thus easily clamped. This is to prevent slipping out of the workpiece from the customer cartridge in the retrograde movement of the Werkstückabnehmerträgers be avoided. The disadvantage of this solution is that due to the fact that the ball can not act directly on the edge of the customer cartridge, a decrease in short workpieces is impossible. These would not fall into the region of the clamping action of the Werkstückabnehmerträgers from the customer cartridge when removing, which would lead to economic losses.

Another disadvantage is the diameter dependence of Abnehmorpatrone on the diameter of the material. Each change of material diameter also requires changing the pickup system, resulting in additional downtime. The problem is the decrease of workpieces with a sensitive surface, z. B. ground material. Here it comes, due to the ball acted upon by spring force, to visible injuries or marks on the workpiece surface area-which leads to quality defects.

Object of the invention

The object of the invention is to eliminate the disadvantages resulting from the application of the load-bearing cartridge with spring-loaded clamps for the removal and removal of short workpieces, as well as the consequent economic losses and qualitative deficiencies.

Explanation of the essence of the invention The invention has for its object to provide a device that allows workpieces and especially short Workpieces safely, without modification in dimensional change and without damaging the lateral surface to remove and

dissipate.

According to the invention, the object is achieved, <sa & on Werkstückabnehmerträger a discharge channel, in front of the Machining point is movable, is arranged so that a workpiece is removable and dischargeable. Ausführungsbelsplel The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawings show Fig. 1: a schematic side view of Anschlagcohse, material stop, Werkstückabnehmererträger and inclined

Ableitrinne, material stop in Ablängposition

 4 shows a schematic representation according to view Y in Figure 2.

Fig. 1 shows an only partially shown machine top part 1 by a pivotable stop axis 2 is mounted. On

the pivotable stop axis 2 is fixedly arranged, the pivot lever 5, which carries the rotatable joint piece 6.

The swing cylinder 7 is fixedly connected to the rotatable joint piece 6. Furthermore, the pivotable stop axis 2 carries the stop holder 4 with material stop 3 and the Werkstückabnehmererträger 8 with pickup cylinder 9. On Werkstückabnehmererträger 8 is the inclined Abführrinne 10th

attached.

Furthermore, Fig. 1 shows the material 11, the material tension 13, the rotary tool 14 with rotary tool holder 15 and the Chips and oils ^! trough 18. With the pivoting guide trough 1 β the guide trough cylinder 17 is connected by a hinge, wherein this on a shoulder

supported in the chip room 19 with its SchwenWuß.

Fig. 2 shows a workpiece 12 shortly before d in demolition, by further, already manufactured workpieces 12 on the inclined Abführrinne 10 and the pivoting guide channel 16, the path of the workpiece 12 is shown schematically. According to Figure 3, the pivot cylinder 7 is in the retracted state, this is the material stop 3, from Stop bracket 4 worn, in the cutting position, while ... 4 shows the swivel cylinder 7 in the extended state, and the inclined discharge chute is located in Pickup position. The operation of the described construction example is the following: After a workpiece 12 tapped by means of turning tool 14 and the material 11 is completely planned, the Turning tool holder 15 with rotary tool 14 is returned by a control cam, not shown, so that the cutting edge of the Turning tool 14am at the end of this return movement outside the circle of the material 11 is located. Same time too

This return movement takes place the pivoting of the material stop 3 in Spindeiflucht, ie before the material eleventh

By retracting the swing cylinder 7 and transmitting this movement by means of joint 6 and pivot lever 5 on the pivotable stop axis 2. Thereafter, the material tension 13 releases the material 11 and under the action of unillustrated pushing means on the material 11, this is in the direction of Wer'-material stop. 3 until this is reached, as shown in Fig. 1. Thus, a next workpiece 12 is cut to length. The material tension 13 detected, the

Material 11 again and the tool holder 15 with rotary tool 14 is moved up to the material 11 to the previously

cut off the cut workpiece 12. At the same time was by extending the swing cylinder 7, with the help of echo η

said transfer elements, the material stopper 3 is pivoted out of the Spindelflucht and brought the inclined Abführrinne 10 in Spindeiflucht, since the Werkstückabnehmerträger 8 and the takeaway cylinder 9 with inclined Abführrinne 10 are also attached to the pivotable stop axis 2. In this case, the inclined Abführrinne 10 is not yet in the field of material processing. Only shortly before the parting of the workpiece 12, the inclined Abführrinne 10 through

Extending the pickup cylinder 9 brought in removal position, as shown in FIG. 2. After removing the workpiece 12 slides

this in the inclined Abführrinne 10 downwards and on the pivotable guide channel 16 in the not shown

Workpiece collection container. At the same time the inclined Abführrinne 10 by retraction of the pickup cylinder 9 in the Starting position spent. After the material 11 is completely planned by the turning tool 14, the entire process is repeated again. Is the material 11, which comes used in rod form for processing, so is not shown

electromechanical means registered this state. The swing cylinder 7 moves out and brings the material stop 3 except Spindelflucht, the pickup cylinder 9 retracts and the Leitrinnenzylinder 17 retracts. Due to the now changed position of the pivotable guide channel 16, the material residue ejected by the following material rod from the material tension 13 opened in this phase can pass over the chip and oil guide channel 18 and over the pivotable material

Leitrinno 16 are led into a collecting container for material residues. Dor arrives at the beginning of the new material bar

also in this way in the same container, whereby a mixing of workpieces 12 and residual material is prevented. Only after the completion of the Erstabstiches the Leitrinnenzylinder 17 moves again and before the Ablängan of the first workpiece 12 is pivoted by retracting the pivot cylinder 7 of the material stopper 3 in the cutting position, after which the work cycle already described workpiece manufacturing begins again.
