Abstract
The utility model relates to a punch device which comprises a punch holder and a punch, wherein a punch groove is formed in the punch holder; a thread is formed on the inner wall of the punch groove; the punch comprises two symmetrical heads and a fixed cylinder; and the fixed cylinder is connected with the punch groove through the thread. According to the scheme adopted by the punch device, the punch achieves a separated structure through the combination of the design that the two heads of the punch can be replaced and the threaded connection, so that when one head of the punch is damaged in use, all that is needed is to screw off the punch and replace the damaged head with a new one instead of replacing the integral punch device, the punch can be reused for production, and the immediate integral replacement is not required. Therefore, the problem that the punch is required to be replaced immediately after being damaged is well solved, the time and the cost are saved, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of device, relates in particular to a kind of punch device.
Background technology
In the process of alloying product, need use decompressor, can use drift in the decompressor, drift carries out punching press to workpiece; The existing drift that is used for decompressor becomes one, and it is used for workpiece is added man-hour, and the position that drift contacts with workpiece is prone to bigger damage; Because of drift is integrated, its local damage is scrapped and can't have been used with regard to integral body, must change whole drift; Influence processing like this, lose time, influence production efficiency.
The utility model content
The utility model purpose is to provide a kind of can exchange the punch device that uses the drift head for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of punch device, comprise punch holder and drift, and offer the drift groove in the said punch holder; Said drift groove inwall is provided with screw thread; Said drift is made up of head and a fixed cylinder of two symmetries; Said fixed cylinder is connected through screw thread with the drift groove.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of punch device of the utility model scheme, through the design that double head can be changed drift, matching thread connects; Make drift realize separate type, in the time of so just can in use of drift, occurring damaging, can whole change punch device; Only need back out drift, change a stature and can produce use once more, not need horse back integral body to change; Well solve drift and damaged the problem that just must at once change, saved time, capital, so also improved the efficient of production.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the stereochemical structure exploded view of a kind of punch device of the utility model;
Accompanying drawing 2 is a kind of punch device cutaway view of the utility model;
Wherein: 1, punch holder; 2, drift; 3, drift groove; 4, fixed cylinder.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1-2 is the described a kind of punch device of the utility model, comprises punch holder 1 and drift 2, offers drift groove 3 in the said punch holder 1; Said drift groove 3 inwalls are provided with screw thread; Said drift 2 is made up of head and a fixed cylinder 4 of two symmetries; Said fixed cylinder 4 and drift groove 3 are connected through screw thread; Can change the design of drift through double head; Matching thread connects, and makes drift realize separate type, in the time of so just can in use of drift, occurring damaging; Need not whole change punch device; Only need back out drift, change a stature and can produce use once more, not need horse back integral body to change.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
