CN202715723U - Double-elastic buffering stamping die - Google Patents

Abstract

The utility model relates to a double-elastic buffering stamping die, wherein a wire spring is mounted on a guide post of a female die; and a silica gel spring is mounted on the wire spring. A function of primary buffering is realized through the wire spring, and when the female die is in contact with the silica gel spring, a function of secondary buffering can be realized through the silica gel spring and the wire spring. Impact produced by the stamping die can be fully absorbed in the production process, and burrs and deformation of a stamping piece caused by impact shock can be effectively eliminated.

Description

A kind of dual elastic buffer punch die

Technical field

The utility model is a kind of dual elastic buffer punch die, belongs to field of mechanical technique.

Background technology

Present punch die all is first-level buffer, impacts because first-level buffer is not enough easily aborning, causes rushing part and burr and distortion occur.

The utility model content

The purpose of this utility model provides a kind of dual elastic buffer punch die, plays first-level buffer by wire spring, and when formpiston touched the silica gel spring, silica gel spring and wire spring played the level 2 buffering effect simultaneously.

Its objective is such realization, a kind of dual elastic buffer punch die is comprised of former, silica gel spring, wire spring, formpiston, guide pillar, guide hole, punch press connector; On the guide pillar on the former wire spring is installed, the silica gel spring is installed on the wire spring, guide pillar is connected in the guide hole, and formpiston is connected with the punch press connector.

Be connected with formpiston by the punch press connector, wire spring plays first-level buffer, when formpiston touches the silica gel spring, silica gel spring and wire spring play the level 2 buffering effect simultaneously, fully absorb aborning the impact that punch die produces, effectively eliminate impact endurance test shock and cause rushing burr and the distortion that part occurs.

Description of drawings

Concrete structure of the present utility model is provided by following examples and accompanying drawing:

Fig. 1, be a kind of dual elastic buffer punch die structure schematic diagram of the utility model.

Among Fig. 1,1, former, 2, the silica gel spring, 3, wire spring, 4, formpiston, 5, guide pillar, 6, guide hole, 7, the punch press connector.

The specific embodiment

Describe the specific works situation that the utility model proposes in detail below in conjunction with Fig. 1, in Fig. 1, on the guide pillar 5 on the former 1 wire spring 3 is installed, silica gel spring 2 is installed on the wire spring 3, guide pillar 5 is connected in the guide hole 6, and formpiston 4 is connected with punch press connector 7.

Be connected with formpiston 4 by punch press connector 7, wire spring 3 plays first-level buffer, and when formpiston 4 touched silica gel spring 2, silica gel spring 2 played the level 2 buffering effect simultaneously with wire spring 3.

Claims (1)

1. a dual elastic buffer punch die is comprised of former, silica gel spring, wire spring, formpiston, guide pillar, guide hole, punch press connector; It is characterized in that: on the guide pillar on the former wire spring is installed, the silica gel spring is installed on the wire spring, guide pillar is connected in the guide hole, and formpiston is connected with the punch press connector.
