Definitions
- the invention relates to a method and a device for cleaning casting cores for foundry parts.
- the object of the present invention is to remedy these drawbacks.
- This invention solves the problem consisting of defining a process and creating devices with which kernels can be not only fragmented, but also totally disaggregated, while causing an eroding effect takeoff of all sand particles, before complete evacuation by gravity in a single phase, preferably without repositioning of the part on its support.
- the first two operations of the method according to the invention allow to obtain the total disintegration of the nucleus, the second operation, namely alternative balancing of the workpiece, further enabling a certain sandblasting effect of the workpiece molded.
- alternative balancing results from the combination of a reciprocating longitudinal movement an alternative transverse movement.
- the reciprocating transverse motion is applied in a parallel plane to the one in which the longitudinal movement is applied.
- the alternative transverse movement is applied in a perpendicular plane to the one in which the longitudinal movement is applied.
- the balancing of the work is performed with an amplitude and an adjustable frequency respectively from 0 to 10 cm and from 0 to 85 Hz.
- the rocking of the piece is performed in combination with the take-up of a clearance J, introducing an additional inertial effect on the sandy mass.
- the amplitude and frequency of the swinging of the piece varies, swing course, according to rules determined according to the internal architecture of the room and the size of the cavities.
- the frequency of rocking is irregular and random.
- a device for applying the basic method according to the invention is characterized in that the high frequency shocks are applied directly on the workpiece using a pneumatic hammer, fixed on a support integral with a frame, arranged so as to strike directly the workpiece by passing the hammer through an orifice formed for this purpose in a fixed support plate, against which the workpiece is held in place by a clamping plate and a chamber cylinder, supplied with low pressure, which constitutes the air cushion, in that the swinging of the part, which takes place according to a horizontal reciprocating movement is obtained through a receiver, comprising the support plate, the clamping plate and the clamping cylinder, connected to the frame vertically by four connecting rods and horizontally by a connecting rod and a double eccentric, rotated by means of a gear motor, and in this that the elimination of sand by gravity is obtained by maintaining in position vertical of the part, by abutting it against a mechanical stop secured to the support plate.
- the receiver preferably consists of two side plates, swan neck shaped, connected together by the support plate and by a connecting plate, supporting the pneumatic cylinder with chamber bearing, on the one hand, against the connection plate and against the clamping plate mounted by means of slides on four slides connecting the support plate to the connection plate, perpendicular to them.
- the vertical connecting rods are connected to the side plates via elastic joints.
- the horizontal connecting rod is connected to the connection plate via of a screed.
- the receiver is fitted with a workpiece box, mounted with a certain clearance between the connection plate and the support plate, supported by four vertical rods fixed against the internal wall side plates by means of elastic articulation, or directly on the chassis by the same means.
- two receivers are mounted on the same frame, both on the other a unique double eccentric, thus ensuring the balancing simultaneous two pieces in line with two hammers tires arranged at each end of the frame.
- the transverse reciprocating movement is obtained through a crankshaft connected to a workpiece holder by at least a connecting rod in that said work-holding capsule is supported by a built by means of four links articulated in planes perpendicular to the crankshaft and in that the frequency of swaying alternative is made irregular and random by variation corresponding to the speed of rotation of the drive motor crankshaft.
- the transverse reciprocating movement is obtained in a perpendicular plane longitudinal movement via a crankshaft connected to the workpiece holder by at least one bearing fixed under the latter, and springs, interposed vertically between the capsule workpiece and the frame, and in that the frequency of the alternating swing is made irregular and random by corresponding variation the rotational speed of the crankshaft drive engine.
- crankshaft is arranged in the longitudinal median plane of the capsule workpiece carrier while the springs are divided into two rows arranged symmetrically with respect to the crankshaft.
- the reciprocating longitudinal movement and the reciprocating transverse movement are combined in a same movement ensuring the overall alternative swing by through two crankshafts arranged vertically between a frame and a workpiece holder support, and in that the frequency of alternative swing is made irregular and random by variation corresponding to the speed of rotation of the drive motor crankshafts.
- the speed variation of the drive motor of the eccentric or the crankshaft is obtained through a electronic dimmer controlled.
- the advantages obtained with this invention consist essentially of in that hollow rooms, of complex architecture, such as internal combustion engine cylinder heads, can be made by molding, without risk of difficulty in removing all of the core, while improving the surface condition of the walls by sanding effect, thus promoting the subsequent flow of liquid fluids or gaseous, intended to circulate in the cavities formed inside of the room, according to a very complex architecture.
- Figures 1 and 2 show a part 1, mounted on a device for fractioning and discharging the casting core of foundry parts according to the invention, comprising a pneumatic hammer 20 with hammer 21, fixed on a support 3 integral with a frame 4 arranged so as to strike the part 1 directly by passing the hammer 21 through an orifice 401, formed, for this purpose, in a fixed support plate 40 with vertical stop 402, against which the part 1 is held by means of a clamping plate 41 subjected to the action of a chamber cylinder 50, supplied with low pressure, constituting an air cushion; said support plate 40 and said clamping plate 41 are part of a receiver 60, connected to the frame 4 vertically by four connecting rods 70 with elastic articulation 71 and horizontally by a connecting rod 72 connected, on the one hand, to a double eccentric 80 driven by a variable speed motor reducer 81 and, on the other hand, via a yoke 431 to a connection plate 43 supporting the chamber cylinder 50 , connecting transversely, in combination with
- FIGS. 3 and 4 represent a part mounted with a clearance J on a device for fractioning and evacuating the casting core, which differs from that shown in FIGS. 1 and 2 only by the presence of sleeve 413, forming a stop, on the slides 412, between the support plate 40 and the clamping plate 41.
- the parts 1 can be directly introduced from above, or, optionally, laterally, into the space thus formed between the two plates 40, 41, it being understood that the stop 402 existing on the support plate 40 limits the penetration of the part 1 in this space, without the need to use any blocking system. Note that on certain flat parts, the parts can be clamped directly, without interposing the clamping plate 41.
- the receiver 60 then being brought at the end of the stroke to the pneumatic hammer 20, by controlled action on the double eccentric 80 via the gear motor 81, the operation can then begin, since the hammer 21 of the pneumatic hammer 20 can - strike directly on the part, passing through the orifice 401 provided for this purpose.
- These hammering actions at high frequency, on the resonant assembly, consisting of the part 1 with its clamping plate 41 and of the chamber cylinder 50 at low pressure, cause, in the vicinity of the natural frequency of resonance of the system, a fractionation and takeoff of the nucleus. This resonance phenomenon can be controlled by acting on the inflation pressure of the chamber cylinder 50 and on the frequency of hammering.
- the sand resulting from the disintegration of the core flows by gravity between the side plates 61, 62 of said receiver and the side members of the frame 4.
- This sand can be discharged at the gradually by a conveyor belt.
- the swing frequency and its amplitude can, respectively, be adjusted, by action on a speed regulator and by action on the double eccentric.
- the disintegration action of the core fragments may be further increased, by providing a clearance J between the so-called clamping plate 41 and the part 1, by adding a sleeve 413 of appropriate length on the slides 412 ( Figures 3 and 4), or, as shown in Figures 5 and 6, by means of two jacks 55 and 56, mounted in opposition and passing through the connecting plate 43, the rod 551 of one of which is connected to the yoke 431 and whose rod 561 on the other comes to bear against the clamping plate 41, or directly against the part 1, to ensure, therein, a clearance J controlled in the horizontal plane; the clamping plate 41 then being secured to its slides by means of locking devices, incorporated in the slides 411.
- the jack 55 ensures the approach of the clamping plate as a function of the thickness of the part and the jack 56 only provides clearance J.
- this arrangement which corresponds to FIGS. 3 to 6, makes it possible to further increase the effect of inertia and, consequently, the collision between the pieces of core; it also facilitates the evacuation of sand, when dealing with parts with fairly complex internal architecture.
- the part 1 is fixed in the receiver 60 by means of a housing 90, mounted with clearance between the connecting plate 43 and the plate support 40, made integral with the side plates 61 and 62 of the receiver, or of the chassis (as shown in the figures), by means of four vertical links 73 fixed by means of elastic articulation 71.
- the part is locked against one of the short sides 91 of the housing, located towards the pneumatic hammer 20, by means of a chamber cylinder 50 bearing against the small opposite side 92 of said housing 90, with or without interposition, d 'a clamping plate 41 . It is thus possible to obtain a combined rocking of the part 1 by means of the receiver 60 and of the housing 90, by accompanying the latter with shocks due to the clearance provided between the housing and the connection plates 43 and d 'support 40.
- Figures 12 to 14 show a frame 1000,190 supporting a workpiece capsule 200 or a capsule support 1000 by means of links 500, springs 700 or crankshafts 180, actuated respectively by a crankshaft 300, one or more connecting rods 400 and a drive motor 600.
- the workpiece capsule 200 is connected to the frame 1000 by means of links 500, which can be common with those allowing the longitudinal swing, provided that their articulations are designed accordingly. (knee pads or double axis of articulation); the lateral swinging being ensured by the connecting rod 400 , driven by a reciprocating movement by means of the crankshaft 300. It is obvious, for the skilled person, that the frequency of the alternating swinging thus created and maintained by the engine 600, could be made random by simple random variation of the speed of rotation of said motor 600 ; which can be easily obtained by means of an electronic variator, the control of which is ensured accordingly.
- the workpiece capsule 200 is connected to the frame 1000 by means of the crankshaft 300, in direct engagement, on the underside of said capsule 200, and two rows of springs 700, arranged on each side of the crankshaft and ensuring the return to the vertical position of the capsule 200, while creating, with this, a vibrating system, which, combined with a random variation of the rotation speed of the crankshaft, obtained as indicated in the example above, will generate and maintain a random alternating swing of said workpiece carrier capsule 200.
- the longitudinal swing can be obtained by alternating sliding of the bearing 201, connecting the workpiece capsule 200 to the crankshaft 300, on the crankpin of said crankshaft, provided that the length thereof is predetermined accordingly to provide sufficient sliding freedom.
- the longitudinal swing and the transverse swing of the support 100 are combined in the circular movement of the crank pin 181 of the crankshafts 180 relative to the drive shaft 182 of these latter.
- the swing thus obtained can be made irregular and random, in this case too, by varying the speed of rotation of the crankshaft drive motor, using the means already mentioned in the other examples.
- the frequency of the longitudinal swing can be made, it also, random by random variation of the rotation speed of the motor assigned to this function.
- the method and the device according to the invention mainly concern the cleaning of the internal combustion engine cylinder heads, but nothing prevents their use for the elimination of the nucleus other foundry pieces with the same internal complexity, subject to minor adaptations.
