Description

The invention relates to the field of processing materials by pressure and can be: used for stamping parts such as pipe nipples. The purpose of the invention is to increase productivity by ensuring the simultaneous upset of both ends of the tubular semi-finished product. Figure 1 shows the device, general view; figure 2 - section aa in figure 1; Fig. 3 is a view B in Fig. 1, Fig. 4 is a tricycle block and a block of punches in the initial position in Fig. 5 - the same, at the time of fixing the tubular billet and tubular semi products in Fig. 6 - the same , at the time of disembarkation. The device contains a matrix block with detachable dies 2, a block of punches coaxially mounted on a drive plate, mounted in the frame 1, mounted in the form of the housing A with a spring-loaded stop finger 5. The device also contains a drive of the stop fingers 5 of the punches installed in the guides 6 mounted on the drive plate 3. The drive is made in the form of a slide 7, kinematically connected with the cam drive 8 of the device. The working end of the slider 7 is fixed by coaxially resistant fingers 5 punches adjustable stops 9. In addition, the device contains a mechanism for transferring tubular (blanks from one landing position to another, which is made in the form of two interconnected plates, one of which 10 Rod holders 11 mounted thereon are mounted for movement along the upsetting axis and connected kinematically with a cam drive 8, and the other 12 with holes 13 for accommodating the rod locks 11 mounted on the frame 1 with the possibility of In the direction perpendicular to the ejection axis and kinematically connected with the cam actuator 8. An additional punch is placed on the plate 10 concentric to the middle pivotal retainer 11. An elastic ring 15 is placed concentrically with the additional punch 14 between the plates 10 and 12 to return in the initial position of the additional punch 14, the Drive of the additional punch 14 is made in the form of two toothed racks and placed between them a gear wheel 16 mounted on the bed 1. The toothed rack 1 7 is mounted on the bed 1 coaxially An additional punch 14 with the ability to interact with it through the striker 18. The gear rack 19 is rigidly connected to the slab 3. The device also includes a loading mechanism 20, a tray 21 and a container 22 for finished products. The device works as follows. In the initial position, the plate, 3 is located in the extreme right position, the dies 2 are open, the plate 12 is lowered to the lowest position so that the upper rod retainer is positioned B, the plate 10 is as close as possible to the plate 12, the slider 7 is positioned in the extreme position, clamping rod clamps 11. Tubular billet 23 loading mechanism 20 is fed to position B and when the plate 3 moves to the left, the thrust finger 5 is pushed into the closed, matrix 2. After that, the slider 7 moves to the extreme right position e, freeing the stop fingers 5, which, under the action of the tubular blank 23, are pressed to the extreme right position. Upon further movement of the plate 3 to the left, the tubular billet 23 is set up in its middle part. When moving the plate 3 to the right, the thrust fingers 5 and the slider 7 occupy the initial position. In this case, the plate 10 for-. The extreme left position at which the rod clamps 11 exit from the cavities of the matrices 2. Then both plates of the transfer mechanism 10 and 12 are moved up to the location of the middle rod clamp 11. In position B, Plate 10 again occupies the position at which the rod clamps 11 are in the cavity of the matrix 2. The matrix 2 is opened, the transfer mechanism, together with the tubular semifinished product landed in position B, is lowered down to the initial position. Matrix 2 closes. A new tubular billet 23 is fed to the position B by the loading mechanism 20. The plate 3, the thrust fingers 5 and the slider 7 carry out the described movements. At the same time, at the position G, the tubular semi-finished product is simultaneously and two-sided

the punch 5 and the additional punch 14, which is described as follows: moving to the left, the plate 3 moves the rack. 19, which by means of the gear wheel 16 moves to the right the gear rack 17, acting on the additional punch 14.

When filling all positions C, D and D with the parts produced during the operation of the transfer mechanism in

the moment of departure of the plate 10 to the extreme left position from the rod to the position D is removed the finished product and the tray 21 enters the container 22.

The proposed device in comparison with the known provides improved performance due to the simultaneous disembarkation of the tubular semi-finished product on both sides and the tubular workpiece in the middle part.
