Abstract

The invention relates to the processing of metals by pressure, in particular to dies for processing sheet material. The purpose of the invention is to increase the reliability of work and the quality of manufacture of first parts. To do this, in the sequential stamp containing the punches 19-22 and the die 3, the safety device L 15 and the detachment 9 are aligned. L 15 has an annular pad 16, and in the liner 9 a hole is made to accommodate the end of L 15. The tape moves along the otlipatel 9. With a working stroke L 15 locks the tape through the hole. The tape is clamped between the annular platform 16 and the end of the liner 9 and lowers to the mirror of the matrix 3. 7 Il.

The invention relates to the processing of metals by pressure, in particular to dies for processing sheet material.

The purpose of the invention is to increase the reliability of work and the quality of manufactured parts.

FIG. 1 shows a sequence diagram of technological transitions; FIG. 2 is a section A-A in FIG. in fig. 3 - bottom stamp plate, plan view; in fig. 4 shows a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. 3 (in the closed position of the stamp in Fig. 6 - the same, in the opened position of the stamp; in Fig. 7 - section G-Y in Fig. 3.

The stamp contains the bottom plate I, on which the holder 2 with a sectional matrix 3 is fixed. On the latter there are molding protrusions 4, guide rails 5 and 6 are installed. On the guide bar 6 there are restrictive abutments 7 removed. In the matrix 3 fixedly fixed - lipatel 8 and 9. Otlipateli 9 are sealed in the form of sleeves. The snubbers 8 and 9 are spring-loaded with respect to the bottom plate 1 by the springs 10. The guide columns 11 and the sleeves 12 orient the sleeve 13 relative to the sectional puller 14. In the latter, catchers 15 are fixed, having annular pads 16, made in the same plane with the surface of the puller 14. The catchers 15 are coaxial with the tacks 9. The yoke 13 is spring-loaded relative to the upper plate 17 spring

When the upper part of the stamp moves downwards, catchers I5 pass through holes in restrictive stops-pullers 7 and enter technological openings of tape 23. Due to the fact that Dispensers 9 are located under catchers 15, no bending moments occur and catchers 15 do not deform the tape 23. Upon further movement down the ring pad 16 catcher 15 interacts with the tape 23.

The snubbers 8 and 9 descend to the mirror of matrix 3. Due to the fact that the annular pad 16 of the catcher 15 touches the belt 23 at the same time as the mirror of the puller 14, the tape 23 does not deform. During the course of the upper part of the stamp, the stop pullers 7 remove the tape 23 from the catcher 15.

Implementation of the invention will improve the reliability of the stamp and the quality of the parts produced.

Claims (1)

Invention Formula A sequential stamp containing movable and fixed plates, working tools mounted on these plates, a puller clamp mounted on the movable plate, means of fixing the material in the form of a catcher mounted on the movable plate, the lateral surface of which is terminated with an end conical step and cylindrical steps the smaller of which is located in cross section next to a conical step and holes for accommodating the end of the catcher, and 18. With the top plate 17 rigidly with -40 containing otplitel, installed punch 19 punch punching technological holes, dividing 20, molding 21, and cutting off 22 punches. On a fixed plate and equipped with a spring, characterized in that, in order to increase the reliability of work and the quality of the parts produced, the dispenser is installed coaxially with the catcher, the opening for placing the end of the catcher is located in the otlipatel, and the surface between the cylindrical steps of the lateral surface the catcher is made in the form of an annular platform located in the same plane with the working plane of the clamp-remover. The stamp works as follows. The processing tape 23 is fed to the first transition, where the punch 19 breaks through the process hole under the catchers 15. Next, the punches 20 perform separation transitions, the punch 21 forms the molding transitions, and the punch 22 cuts off the finished part. inclining On a fixed plate and equipped with a spring, characterized in that, in order to increase the reliability of work and the quality of the parts produced, the dispenser is installed coaxially with the catcher, the opening for placing the end of the catcher is located in the otlipatel, and the surface between the cylindrical steps of the lateral surface the catcher is made in the form of an annular platform located in the same plane with the working plane of the clamp-remover. -h I I I I I -f f | I +1 .G ilh g 1 fPu2.2 + + + + H L T.
