Abstract

The utility model provides a punch guiding structure of a stamping die. The punch guiding structure of the stamping die is characterized in that the unloading plate of the punch is provided with two guiding sections. The two guiding sections are not only used for guiding the front end of the punch but also used for guiding the back end of the punch, so that dual guidance for the punch is realized. Therefore, the punch guiding structure ensures that the punch has low probability of destabilization during pressing stroke, the safety of the punch is ensured, and the punch is not easy to break off.

Description

The drift guide frame of diel

Affiliated technical field

The utility model relates to the punch process mould, is specifically related to be used for the drift guide frame of precise punching die.

Technical background

During punch process, especially precision stamping adds man-hour, because punch is very tiny, because machined material generation state variation, or because the stability of process equipment changes etc. to some extent, all might cause punch to fracture easily.

In the current techique, most of precise punching die drift mainly relies on stripper to lead, and the targeting part of drift is that the rear portion of drift and the gap of stripper are very big, are not controlled near the straight body part of the front end of drift.Therefore,, in punching stroke, occur unstability easily, cause drift to fracture because the length of drift is longer relatively in the case.

The utility model content

In order to overcome the problems referred to above effectively, the utility model provides a kind of drift guide frame of diel.

The drift guide frame of the diel that is provided is primarily characterized in that the stripper of the drift of guiding diel has two guide sections.These two guide sections not only lead to the front end of drift, are also led in the rear end of drift simultaneously, realize the dual guiding to drift, thereby can guarantee in punching stroke, drift is not easy to occur unstability, guarantees the safety of drift, is not easy to cause drift to fracture.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

The specific embodiment

Please refer to Fig. 2, this graph expression the drift guide frame of the related diel of the utility model, stripper 2 parts at this drift guide frame, not only the front end at drift 1 is provided with guide section A, rear end at drift 1 also is provided with guide section B simultaneously, realizes the dual guiding to drift.Thereby can guarantee that in punching stroke, drift is not easy to occur unstability, be not easy to cause drift to fracture.

Claims (1)

1. the drift guide frame of diel, it is characterized in that: be to guide the stripper of the drift of diel that two guide sections are arranged, these two guide sections not only lead to the front end of drift, are also led in the rear end of drift simultaneously, realize the dual guiding to drift.
