SU90623A1 - Stamp-form for punching galoshes in presses using two semi-matrices - Google Patents

Description

The subject of the invention is to use a stamp-shape for stapling galoshes in presses with the use of two semi-matrices. The well-known stamps with two semi-matrixes have the disadvantage that the core is not self-aligning.

In the stamped form described, this disadvantage is eliminated by the fact that for the self-mounting of the core in it, the butt part of the latter is made in the form of “dovetail tail, interacting with movable semi-matrices having a profile in the clamping part that is negative with respect to the butt of the core.

FIG. 1 shows one half of the die-fore with core in front; in fig. 2 and 3 - the same in a section on AA.

The stamp-forum is made with the use of movable semi-matrices

1 and 2, MOHTHpoBiHHHbix on the table 3 of the press and B3 (supported with the core 4. The core 4 is fixed on the pins x 5 of the plugs 6 n and spring-loaded on the carrier platform 7 of the conveyor 8 of the press with the help of the spring 9. The interaction of the core 4 with the half matrices / and 2 is carried out with Using the Koml 10 at the core, made in section in the "dovetail" type. Movable semi-matrices} and

2 have in their clamping part of the profile, negative with respect to the core 10 of the core 4. The plane 11 of the core of the core. P; 1Ko above the plane 12 of the armhole of the die.

In the process of working the stamp-form and feeding of the cores-conveyor 8, the platform 7 v. Enters the groove of the table 3 of the press.

When reduced, and semi-matrix 1 2 plane 12 are on the plane // and lower the core /, compressing the spring 9.

At the end of the landing of the core 4, the plane 13 sits on the plane 14, which ensures the self-alignment of the core 4 with respect to the njTaM n-shape, the shape of a semi-matrix / and 2.

Subject invention

1. Stamp-form for stamping galoshes in presses with the use of two semi-matrixes, characterized in that for self-installing foam cores, the butt part of the latter is made in the form of a “swallowtail”, which interacts with the sponge semi-matrixes that have a negative profile in their clamping part in relation to the butt of the core.

2. Form of die stamping according to and. 1, characterized in that the heart of the weir is spring loaded and the bearing platform of the press conveyor.
