Side piercing tapered wedge mechanism with material pressing function

Abstract

The invention discloses a side piercing tapered wedge mechanism with a material pressing function. The side piercing tapered wedge mechanism comprises an upper sliding block, a side guide block, a lower sliding block, a bottom guide block and a piercing head assembly, wherein the upper sliding block is fixedly mounted at the bottom of an upper template; the side guide block and the bottom guide block are fixedly mounted at the top of a lower template; the lower sliding block and the piercing head assembly are mounted on the bottom guide block in a sliding manner; the side piercing tapered wedge mechanism further comprises a material pressing plate and a return assembly; a material pressing plate spring is mounted on the lower sliding block; a through hole is formed in the piercing head assembly; a piercing head avoiding hole is formed in a material pressing plate; the material pressing plate is connected with the bottom guide block in a sliding manner; the material pressing plate spring penetrates through the through hole and presses against the material pressing plate; a piercing head on the piercing head assembly penetrates through the piercing head avoiding hole; and the return assembly is mounted on the side guide block and is connected with the lower sliding block. The side piercing tapered wedge mechanism disclosed by the invention can complete the work of material pressing first and then piercing for a hole in the side surface of a product part, and is simple in structure and small in installation space; the piercing head is convenient to remove; and the development cost of a die is reduced.

Description

technical field [0001] The invention relates to a side punching wedge mechanism, in particular to a side punching wedge mechanism with a pressing function. Background technique [0002] Many stamping parts in the automobile body-in-white have complex shapes. There are often holes with different functions on the body-in-white product parts, and some holes located on the side of the product parts must be punched with a wedge mechanism. [0003] In the prior art, the side punching cam mechanism such as figure 1 As shown, its structure includes an upper base 100, a driving block 200 and a sliding block, the sliding block includes a sliding block body 300 and a sliding guide block 400, the bottom of the sliding guide block 400 is provided with a boss 500, and the sliding guide block The top of 400 is provided with a screw through hole; the sliding block body 300 is provided with a groove 600 matched with the boss 500, and the bottom of the groove 600 is provided with a threaded ...

AI Technical Summary

Problems solved by technology

[0004] The side punching wedge mechanism has complex manufacturing process, high procurement cost, large size, and no pressing function. For some small stamping steel plate molds, it is easy to increase the mold cost.

Since there is no pressing function, the punching quality cannot be guaranteed
