Embodiment Construction

[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] see figure 1 and figure 2 Shown, a kind of specific embodiment of multi-standard punch of the present invention. A multi-standard punch, including a punch body 1, the punch body 1 is a cylindrical structure, the middle and rear part of the punch body 1 divides the punch body 1 into a front section 11 of the punch and a punch front section 11 through a step 10. The back section 12 of the head, the step 10 is provided with an annular groove 100, and a spring 2 is arranged in the groove 100, and the spring 2 is sleeved on the front section 11 of the punch, and the upper part of the spring 2 is arranged There are end caps 20 . Arranged like this, since the groove on the punch body is provided with a spring, it can play a good buffering effect, and the spring will not shift.

[0011] Further, a first square die 121 and a second...

Abstract

The invention discloses a multi-specification punch and belongs to the technical field of stamping. The multi-specification punch comprises a punch body which is of a cylindrical structure. The middle rear portion of the punch body divides the punch body into a punch front section and a punch rear section through a step, the step is provided with an annular groove, a spring is arranged in the groove and is in sleeved connection with the punch front section, and the upper portion of the spring is provided with an end cover. Compared with the prior art, due to the fact that the spring is arranged in the groove of the punch body, a very good buffer effect can be achieved, and the spring is not shifted; the punch is no longer single in structure, the requirements of punching products of various specifications can be met, the actual production requirements are met, the production costs of enterprise are lowered, and the economic benefit is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of stamping, in particular to a multi-standard punch. Background technique [0002] The punch is a metal part installed on the stamping die, which is used in direct contact with the material to deform and cut the material. The current punch is for direct punching without cushioning function, and the end face of the punch has no bevel, burrs are prone to appear on the edge of the product after punching, which affects the quality of the product. cost, and the single structure of the current punch cannot meet the needs of stamping products of different specifications. The above problems need to be solved urgently. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a multi-standard punch. [0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions: a multi-standard punch, including a punch b...
