Description

The invention relates to the field of metal forming, and more specifically to equipment for stamping rod parts.

The well-known automatic machine for stamping sterile-5 reaper parts contains a die tool for metal forming, forming the head or flange and pushing the part and a horizontal slider with a wedge drive installed in the guides of the frame mounted on a vertical press [1J The low productivity of this machine is due to several stamping operations in one position] 5 research institutes.

The purpose of the invention is improving the performance of the machine.

This is achieved by the fact that the machine is equipped with a rotary disk around the horizontal axis with matrices fixed around its circumference, with a semicircular cavity made in the bed, a disk installed in this cavity, and a stamping tool placed in the cavity zone on both sides relative to drive. In addition, the stamping tool is equipped with a support punch for moving the workpiece by a predetermined amount at the position of the set of metal. thirty

In FIG. 1 shows the proposed machine, a General view; in FIG. 2 - section A — A of FIG. 1; in FIG. 3 - section B — b of FIG. 1.

The frame 1 of the machine is fixed on the table of the universal vertical press 2 and on the stand 3, fixed to the foundation. In the guides 4 of the frame 1 there is a horizontal slider 5 with a molding punch 6. The back of the slider 5 interacts with the wedge 7 fixed on the slider in the press 2, and the wedges 9 of the reverse stroke, also fixed on the slider of the press 2. In the semicircular cavity 10 of the frame 1 is installed a disk 11 rotatable around a horizontal axis with matrices 12 radially spaced around its circumference. Disk 11 is driven by a ratchet mechanism 13 using a hydraulic cylinder 14. An exact stop is achieved by using a locking dog 15 from the pneumatic cylinder Ndra 16. The disk 11 is mounted on a shaft 17, rotating in bearings 18 mounted in the frame 1. In the matrices 12, the bushings 19 and 20 are pressed in. The sleeve 20 has an opening, the initial zone of which is conical. Both sides of the cavity 10 are provided with openings arranged coaxially with the matrices 12 for the punch tool: ejector 21, metal set punch 22, support punch 887058 by 23, forgings ejector 24 and molding punch 6. Ejector 21, metal set punch 22 and support punch 23 are driven by individual hydraulic cylinders. The forger 24 forgings is moved by a pneumatic cylinder. A support plate 25 is attached at the molding position. A transport device 27 and a pusher 28 are used to feed the workpiece 26. Forgings are removed by a chain conveyor 29 in a container 30.

The machine works as follows.

Measured billet 26, heated to the required length, is transported by the transport device 27 to the loading position. The pusher 28 pushes it with its unheated end into the sleeve 20 of the matrix 12. The locking dog 15 with the pneumatic cylinder 16 is disengaged from the rotary disk 11. The hydraulic cylinder 14 rotates the disk 11 through the ratchet mechanism 13. The pneumatic cylinder 16 lowers the dog 15. The end of the rotation of the disk 11 coincides with the lowering of the dog 15 into the cavity of the disk I. At the position of the set of metal, the support punch 23 moves the workpiece 26 in the matrix 12 until its cold end leaves the rear end of the matrix by a length that provides the necessary set of metal for the head. In this case, the punch 23 forms a closed annular cavity with the matrix 12. Then, the punch 22 of the metal set upsets the preform, filling the annular cavity, until the cold end of the preform is established flush with the rear end of the die 12. Simultaneously, the press stroke 2 is made, the horizontal slider 5 moves, forming the forging head resting on the plate 25. During the return stroke the press slider, the ejector 21 shifts the forging, creating a gap with the internal cavity of the matrix 12. The final removal of the forging is carried out during the next cycle at the position of the ejector 24. Stamped forging and falls on the chain conveyor 29 and is removed into the container 30.

The rotation drive is returned to its initial position at the same time as the stamping tool is returned to its original position, as is the loading of a new workpiece. The cycle repeats.

Using an automatic machine can increase productivity in the manufacture of hot stamping rod parts of considerable length.

at 23, the dumper 24 of the forgings and the molding punch 6. The ejector 21, the punch 22 of the metal kit and the supporting punch 23 are driven by individual hydraulic cylinders. The puller 24 is moved by a pneumatic cylinder. A support plate 25 is attached to the forming position. A transport device 27 and a pusher 28 are used to feed the workpiece 26. The removal of the first forging 1 is carried out by the chain conveyor 29 into the container 30. The machine works as follows. The billet 26 is heated to the "required length, the transport device 27 is delivered to the loading position. The pusher 28 pushes it with an unheated end into the sleeve 20 of the matrix 12. The locking pawl 15 with the pneumatic cylinder 16 is disengaged from the rotary disk 11. The hydraulic cylinder 14 through the storage mechanism 13 rotates the disk 11. The pneumatic cylinders 16 lowers the pawl 15. The end of the rotation of the disk 11 coincides with the pulling of the pawl 15 and the pnevmociliidr 16 lowers the pawl 15. The end of the rotation of the disk 11 coincides with the pulling of the pawl 15. into the cavity of the disk 11. At the position of the metal set, the reference luanson 23 moves the workpiece 26 in the die 12 to the exit of its cold end from the back end of the die to a length that provides the necessary set of head metal. When this punch 23 forms with the matrix 12 a closed annular cavity. The punch 22 of the metal kit then precipitates the workpiece, filling the annular cavity, until the cold end of the workpiece is flush with the back end of the matrix 12. Simultaneously, the press 2 is moved, the horizontal slide 5 is moved, forming the forging head supported on the plate 25.
