Description

The invention relates to the processing of metals by pressure, in particular, to tooling for sheet metal forming. A known stamp for making loops from sheet blanks with a bent edge, containing a bending tool mounted on a movable and fixed plate. The disadvantage of this stamp is the absence of mechanisms that automate the loading of blanks and the removal of finished parts. Closest to the proposed invention is a stamp for making loops from sheet blanks, containing a tool mounted on the movable and fixed plates for bending the edge of the workpiece, as well as a stop installed on the bottom plate and a slide gate mechanism for feeding and removing the workpiece 2. However, loading into the well-known stamp of N. Syhanisia 11a, which does not allow fully automated the manufacturing process and loops. The aim of the invention is to automate the process of making loops. To achieve this goal, the depressed stamp is equipped with a perpendicularly installed nagging mechanism for machined workpieces equipped with a pneumatic cylinder with a pusher, and the feeder gate is connected through a cable with a movable plate and is spring-loaded in the feed direction. FIG. 1 given the proposed stamp, longitudinal section; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2. The stamp consists of a movable plate 1 with a punch 2 fixed to it for bending and a stationary plate 3 with a matrix 4 fixed to it, guides 5 and 6 along which the fork-slide 7 moves, with the workpiece 8 8 installed perpendicular pivotally guides 5 and 6, pneumatic cylinder 10, and also a tension spring 11 connected to plug gate 7. On the side opposite from spring 11 to fork 3. /; 7, a cable 12 is connected to the ke-gate 7, connected by a crawling system of blocks 13 to a movable plate 1. A guide lug 14 is made on the guide 5, the lower flatness of which is separated from the fixed plate at a distance greater than the BOSS part. The stamp works as follows. In shop 8, a zafuzhat-s-batch of billets 9, the presser pneumatic cylinder 10 is turned on and the foot is pressed against the fork 7. Then the press is turned on for automatic work. As the slide moves down the cable 12 through the system of blocks 13 moves the plug-gate-7 away from the magazine 8, thereby stretching the spring 11. The pressure stroke and, consequently, the distance at which the plug-gate is located, is equal to the width of the cover 9 , In the extreme lower position of the press ram, the pneumatic cylinder U is inserted, advancing a stack of blanks 9 by the thickness of one blank. When the press ram moves upward, the cable 12 is released, the spring 117 is compressed,. moves the plug 7 forward, and the latter seizes the part and feeds it to the thrust protrusion 14. With the last pin, it pulls the yo-yo yyyyu pianone 1 curls the loop. At the end, the slide of the slider, the clamping belt 6 and No. 10, sends the workpiece to the feed position, and when the slide is moved upwards, the fork-slide 7, when the next workpiece is flexible, pushes the finished workpiece, since the latter pushes the finished workpiece below the bottom and the plane thrust ledge 14. The press works up to

Fig. 1 releases the kilogram 8, eats a choke of the presser 11 and 1 or 10 of the container 10 to the left, releasing the magazine 8 to load the next batch of blanks and the process repeats. The use of the proposed stamp of automatic feeding of blanks and removal of stamped parts increases labor productivity and improves the conditions for safe work on the stamp. An invention of a stamp for making loops from sheet blanks, comprising a tool mounted on the moving and fixed plates for bending the edge of the bale; and a stop and slide mechanism for feeding and removing the workpiece mounted on the bottom plate, characterized in that, in order to automate the manufacturing process. loops, it is provided, installed perpendicular to the feed mechanism, with a magazine for workpieces, equipped with a 1M pneumatic cylinder with a pusher, and the feed mechanism gate is connected via a cable with a movable plate and spring-loaded in the feed direction.
