Abstract
The utility model provides a replacing device for a punch of a punching machine. The replacing device for the punch of the punching machine comprises a punch seat, a dowel and a punch. When the punch is replaced, the dowel is pulled out of a base hole, the punch is taken off, the end portion of an alternative punch is inserted into the punch seat, the hole of the punch seat is aligned to the punch hole, and the dowel is inserted into the hole to fix the punch, so that the punch is prevented from sliding down or rotating. The replacing device for the punch of the punching machine achieves replacing of the punch of the punching machine conveniently and rapidly, and improves stability and safety of the punch.
Description
Technical field
The utility model relates to a kind of perforating press field, and the drift that is specifically related to a kind of perforating press is changing device more.
Background technology
Perforating press uses very extensive in existing industrial production, and existing perforating press drift mostly is non-exchange; Rare a few money can be changed the perforating press of drift, and the method for changing drift is also very complicated, often need to realize by changeing the modes such as screw.Bring a lot of inconvenience for user's use.
The utility model content
Can't change drift or change the complicated problem of drift for solving existing perforating press, the utility model provides more changing device of a kind of perforating press drift, has realized convenience and safety that drift is changed.
The utility model is achieved through the following technical solutions: a kind of drift of perforating press is changing device more, comprise: punch holder, pin and drift, punch holder is located on the perforating press, hollow cavity is arranged in the punch holder, the nose of punch undersized is in cavity size, nose of punch just can be inserted in the punch holder cavity, and there is the hole of running through punch holder at the punch holder middle part, and the size in hole and pin coincide.Supporting drift also is the end with the hole that coincide with the pin size.During installation nose of punch inserted the cavity in the punch holder, with the hole alignment, then pin is passed in the hole and run through whole punch holder, realized the installation of drift.The drift that fixedly makes of pin can't rotate or landing at work.
The beneficial effects of the utility model are: it is convenient, fast to have realized that the drift of perforating press is changed, and stability and security when having improved drift work.

Specific embodiment
A kind of drift of perforating press is changing device more, comprising: punch holder 2 and pin, punch holder are arranged on the perforating press, and hollow cavity 3 is arranged in the punch holder, and there is the hole 4 of running through punch holder at the punch holder middle part, and the size in hole and pin coincide.Supporting drift 5 also is the end with the hole 1 that coincide with the pin size.
When changing drift 5, pin is extracted in the hole 4 of punch holder, taken off drift 5, punch holder 2 is inserted in drift 5 ends that needs are changed, alignd with bore of the punch 1 in the hole 4 of punch holder, pin is inserted described hole with fixing drift 5, prevent drift 5 landings or rotation.
Claims (1)
1. the drift of perforating press changing device more is characterized in that, comprising: punch holder, pin, drift have the cavity of a hollow in the described punch holder; There is the hole of running through punch holder at the punch holder middle part, and pin can embed described hole; Nose of punch is with the hole that matches with the pin size, and the nose of punch size is less than punch holder inner chamber body size.
