(54) MANIPULATOR FOR COLLECTED MACHINES

I

The ejection relates to foundry engineering and can be used in chill casting machines and lines for the production of shaped hollow castings.

A mechanism is known for removing castings from chill sections and transferring them to a receiving device consisting of a bed, in the bore of which a movable cylindrical sleeve is installed, equipped with a crank. On the crank pin with the help of a rubber bush is installed tra versa. On the traverse there are two pin-mounted, OA, one of which interacts with the fixed sleeves of the bed, and the other with the centering sleeves of the chill sections mounted on the guard table tl.

Also known is a stripper of castings in a chill machine, equipped with tongs suspended on levers in the form of a pantograph, lifting and then turning around the vertical axis t2.

The casting transfer trajectory finds “c in a horizontal plane and crosses the scoter” at the possible presence of the serving personnel, and the use of special enclosures clutters the near-machine space, making it difficult to stitch the machine.

The casting at the time of separation or chill mold moves not along the vertical, but along a train, which leads to scuffing both in the casting and in the chill mold, thereby reducing its durability. In addition, during casting, castings are captured by the side walls, which is completely unacceptable for thin-walled castings; the side walls will deform from the forces required to hold them in the hopper.

The purpose of the invention is the expansion of technical capabilities, ensuring the safe transfer of castings.

Claims (2)

The goal is achieved by the fact that the manipulator for chill machines, containing a traverse with a gripping mechanism and taking shuga-driven casting screws, a traverse movement mechanism, made in the form of a system of levers, equipped with a device for cleaving sprues, made in the form of a system of levers with a drive , and the mechanism for gripping and casting of castings is equipped with hinged hooks with snaps to hold the castings. The levers of the grass moving mechanism {s can be mounted on horizontal axles, and it is advisable to provide the traverse with an additional drive. FIG. 1 depicts a manipulator; in fig. 2 - section A-A in FIG. 1. The manipulator consists of a gearbox 1 with a rack and pinion drive, on the outgoing ends of the shafts 2 of which on both sides 3 types of pantograph roar are mounted, the upper ends of which are pivotally connected by semi-axes 4 with the crossmember 5. Traverse 5 made of two elements: element 6 pivotally: fixed on the levers 3 pantographs, and the element 7 hinge is connected to element b and has the ability to be deflected on it towards the transfer of castings using an actuator 8 mounted on element 6 and hingedly connected to element 7 On the movable element 7 tr The obverse 5 has two cylinders 9, the sleeves of which are rigidly connected to the movable element 7, the traverse 5, and their rods engage in interaction with the upper end of the sliders 10 s. They can be moved along the cylinder liners 9. To the sliders Yu are attached a double cylinder 11 of the twin cylinder 12, including a cylinder 13 of a locking mechanism and a cylinder 14 of a mechanism for spaling of sprues. The rod cavity 15 of the cylinder 13 i is separated from the piston cavity 16 of the cylinder 14 by the seal 17, the rod 18 of the cylinder 13 of the locking mechanism is passed through the rod 19 of the cylinder 14 of the mechanism for splicing gates. Between the rods 18 and 19 is installed seal 2O. On the cover 11, the holder 21 is strengthened; between the cheeks 22 of which axes 23 are installed knives 24 for splicing sprues, each of which is made in the form of a two-arm lever, the free end 25 of which interacts with the cop lecturer of the sprue system 26, and the other x hinge is hinged the rod 19 installed in the stud 28. To the lower part of the holder 21, the mandrel 29 is attached and centered on it with the aid of ca. 30. In its lower part the mandrel 29 has a centering end 31. In the end slot 32 of the mandrel 29: a lever system pivot hinge hooks 34, installed their upper ends on the axis x 35, and the lower ends, provided with a protrusion 36, hold the casting 37 by weight for its lower edge 38. The lever system 33 is connected with the rod 18 of the cylinder 13 with the rod 39, which passes through the rod 18, is fixed in it with the help of the ledge 4O and the nuts 41. The manipulator tor works as follows. . After the crystallization from the casting 37 is completed, the rod is withdrawn from its internal cavity, partially opens the chill molds 42 and 43, during which the casting 37 is still held in them, the yoke 5 with the aid of the gearbox 1 and the levers 3 are installed over the casting 37 The cylinders 9 then lower the slides 10 together with the mechanism for gripping the castings and forcing off the sprues, while the mandrel 29, entering the cavity of the casting 37, aligns itself by means of a cone 31. After applying pressure to the piston cavities 16 and 44 of the cylinders 13 and 14 respectively, the rod 18 , come Through the bar 39, the lever system 33 rotates the hinged hooks 34, which interact with their projections 36 with the bottom end 38 of the casting 37, and the knives 24, interacting with their ends 25 with the collector of the gating system 26, separate it from the casting 37. After complete removal of the part of the mold 43, a casting 37 is withdrawn from a part of the mold 42 by turning the element 7 of the crosshead 5 of the drive 8. After the lifting of the pickup with the casting 37 using cylinders 9, gear I, turning the levers 3, 1x; device 45, drive 8 returns the element 7 of the crosspiece 5 to its original position, and the cylinders 10 lower the casting 37. The pressure is applied to the cavity 46 of the cylinder 14 of the squill mechanism, puller 19, raised, turns the blades 24 to the outer side 29. When pressure is applied to the stem cavity 15 of cylinder 13, rod 18 ,; raising the rod 39 of the lever system 33, removes the hinged hooks 34, freeing the casting 37, which is lowered onto the screw device 45. The proposed design of the manipulator for the chill machines allows the JtMtb technological capabilities to expand due to the mechanism of the splicing of castings combined with the gripping mechanism and the removal of the mold with the mechanism of cleaving the moldings combined with the gripping mechanism and removing the mold, the mold has a mechanism for cleaving the moldings combined with the gripping mechanism and the removal of the mold, and the removal of the casting mechanism combined with the gripping mechanism and the removal of molds. ensure the safe transmission of castings. The use of a cross-beam, made of two elements, one of which has the ability, with the missions of capturing casting of lithium stones mounted on it, to deviate relative to the first one in the transfer direction, makes it possible to significantly reduce the size of chill machines. In addition, c (The castings deteriorate due to the elimination of their deformation during transport by the puller, since the casting is held with protrusions of the hooks of the gripping and removal mechanism on the body, and not compressed by ticks on the side steaks.
