Abstract
The utility model relates to a punching head consisting of a tubular punching body and a press knife, wherein an elastic dilatation joint is arranged along the axial on the side wall of the punching body and the press knife, an elastic body is fixed in the punching body, a press head is arranged on the end of the elastic body, the elastic body adopts a spring, and the side wall of the punching body caves in to hold and fix the elastic body. The utility model overcomes the defects of excess hardness, absence of elasticity and liability to break off due to jamming of a punching head in the prior art. The elastic dilatation joint greatly reinforces the elasticity and the anti-jamming performance of the punching head. The utility model has the advantages of simple structure, endurance of punching, long service life and high quality of punching.
Description
Affiliated technical field
The utility model relates to a kind of eyelet punch.
Background technology
Traditional eyelet punch, its punch body is all made by seamless steel pipe, forms cutter head in the end of punch body.Above-mentioned eyelet punch, its punch body and cutter head are made by single material, and hardness is too high, poor flexibility, punch body rupture because of obstruction easily.
Summary of the invention
For overcome the hardness of eyelet punch in the prior art too high, lack flexibility, problem that punch body ruptures because of obstruction easily, the utility model provides a kind of eyelet punch, the elastic telescopic performance of this eyelet punch is strong, be difficult for stopping up.
The technical scheme that its technical problem that solves the utility model adopts is: by tubulose dash body and stamping knife portion connects and composes, be provided with elastic expansion joint at sidewall upper edge axis towards body and stamping knife portion.
Fixing elastomer in the body, elastomeric end assembling roof pressure head.
Elastomer adopts spring, caves in towards the sidewall of body, embeds and fixing elastomer.
The utility model has strengthened the elasticity and the anti-blocking performance of eyelet punch greatly by the design of above-mentioned elastic expansion joint, has simple in structure, anti-punching press, long service life, advantage that punching quality is high.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1
The specific embodiment
As shown in the figure, the utility model by tubulose dash body 1 and stamping knife portion 2 connects and composes, adopt two kinds of metal materials that hardness is different towards body 1 with stamping knife portion 2, be provided with elastic expansion joint 3 at sidewall upper edge axis towards body 1 and stamping knife portion 2, towards body 1 interior fixedly elastomer 4, above-mentioned elastomer 4 adopts spring or other elastomeric materials.The end of elastomer 4 assembling roof pressure head 5 caves in towards the sidewall of body 1, makes it to embed and fixing elastomer 4.Under user mode, if press stamping parts such as having expired the scraps of paper in the drift, can be after taking out tamper, the elastic reaction by elastic expansion joint 3 restores to the original state drift.
Claims (3)
