Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a stamping die thick material cutting structure comprises an upper die 1 and a lower die 6, wherein a lower die knife edge 5 is vertically arranged at one end of the upper surface of the lower die 6, an equal-height screw 2 is vertically arranged at one end, close to the lower die knife edge 5, of the upper die 1, a limiting groove 101 is arranged above one end of the upper die 1, the equal-height screw 2 is arranged inside the limiting groove 101 and penetrates through the upper die 1, a spring 201 is arranged at the upper end of the equal-height screw 2, the bottom end of the spring 201 is in contact with the bottom surface of the limiting groove 101, and limiting layers are arranged at two ends of the spring 201 through matching of an end cap at the top end of the equal-height screw 2 and the bottom surface of;

the bottom end of the equal-height screw 2 is in threaded connection with a cutting punch 4, so that the cutting punch 4 and the equal-height screw 2 can be synchronously displaced, the cutting punch 4 can be conveniently lifted through the resilience of a spring 201, the pulling force is reduced, a push block 3 is sleeved on the equal-height screw 2 between the cutting punch 4 and the bottom of the upper die 1, a threaded connection hole 301 is formed in the outer side wall of the push block 3 and used for being externally connected with a push rod and conveniently applying a pushing force, a moving groove 303 with a rectangular cross section is vertically formed in the middle of the push block 3, the equal-height screw 2 penetrates through the moving groove 303, and the push block 3 can be conveniently horizontally moved between the cutting punch 4 and the upper die 1;

a sliding block 302 in a trapezoidal structure is integrally formed at the bottom of the pushing block 3, a sliding groove 401 matched with the sliding block 302 is formed at the top end of the cutting punch 4, and the inclined angle of the inclined edge of the sliding block 302 is 40 degrees, so that the sliding block 302 and the sliding groove 401 can move relatively along the inclined edge;

the inner side surface of the bottom edge of the cutting punch 4 is attached to the outer side surface of the lower die edge 5, so that the interaction during cutting is guaranteed, and the cutting is realized through mutual staggering.

The working principle is as follows: when in use, firstly, a plate is horizontally placed above the lower die knife edge 5, a push rod is installed at the threaded connecting hole 301 of the push block 3 in a threaded manner, as shown in fig. 2, the push block 3 is pushed rightwards through the push rod, so that the slide block 302 and the chute 401 displace along the inclined edge, the cutting punch 4 is pushed to move downwards to a dead point, the cutting punch is matched with the lower die knife edge 5 to cut the plate, in the process, the equal-height screw 2 synchronously moves downwards along with the displacement of the cutting punch 4, so that the spring 201 at the upper end of the equal-height screw 2 is pressed, as the push block 3 is provided with the moving groove 303, the push block 3 is not blocked by the equal-height screw 2 to move horizontally, after the cutting is finished, the push block 3 is pulled leftwards to enable the slide block 302 to be matched with the chute 401 gradually, at the moment, the distance between the cutting punch 4 and the bottom surface of the upper, the cutting punch 4 is driven to move upwards, and the pulling force is reduced, so that the cutting punch 4 is separated from the lower die knife edge 5, and the plate can be further processed or taken out conveniently.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
