Abstract
The utility model relates to a punch device with replaceable heads. The punch device with replaceable heads comprises a punch seat and punch heads, wherein the punch seat is provided with a punch groove. A positioning concave groove is arranged on the inner wall of the punch groove. The positioning concave groove is extended to the inner side of the punch groove from the port of end of the punch groove. Three corners are arranged between the two ends of the positioning concave groove. The corner is perpendicular type. A cylinder fixture block is arranged on the punch heads. A positioning clamp is arranged on the cylinder fixture block. When equipped, the punch heads are fixed in the positioning concave groove inside the punch seat through the positioning clamp. Through the structure design of the positioning concave groove, basing on the punch structure in the prior art, the punch device with replaceable heads has the advantages of achieving to replace the punch heads, having no influence on the using effect of the punch heads, solving the problems of scrapping the whole punch after the damage, reducing the cost and the resources and improving the full utilization rate of the material.
Description
Technical field
The utility model relates to a kind of punch device, relates in particular to a kind of punch device of head-exchangeable.
Background technology
In the process of alloying product, need to 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, it is used for workpiece is added man-hour, the position that drift contacts with workpiece is prone to larger damage, because drift is integrated, its local damage has been scrapped with regard to integral body, and the drift that is used for decompressor generally adopts alloy steel cost larger, in case scrap the raising that will cause production cost, the waste of resource.
Summary of the invention
The utility model purpose is the punch device that a kind of head-exchangeable is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of punch device of head-exchangeable, comprise punch holder and drift, and offer the drift groove in the described punch holder; Described drift groove inwall is provided with detent; Described detent extends to the drift groove from drift groove port inner, is provided with three corners between the two ends of this detent; Described turning is rectangular in shape; Described drift is provided with the cylinder fixture block; Described cylinder fixture block is provided with the location dop; During installation, drift is fixed in the detent in the punch holder by the location dop.
Preferably, described detent, location dop have respectively 4.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The punch device of a kind of head-exchangeable of the utility model scheme, structural design by detent, on original punch structure, drift is realized interchangeable, do not affect again drift effect in use, well solve the problem that integral body was scrapped after drift damaged, provided cost savings and resource the rate that takes full advantage of of the material of raising.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural perspective of the punch device of a kind of head-exchangeable of the present utility model;
Accompanying drawing 2 is the cutaway view of the punch device of a kind of head-exchangeable of the present utility model;
Wherein: 1, punch holder; 2, drift; 3, drift groove; 4, detent; 5, cylinder fixture block; 6, location dop.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1-2 is the punch device of a kind of head-exchangeable described in the utility model, comprises punch holder 1 and drift 2, offers drift groove 3 in the described punch holder 1; Be provided with four detents 4 of circular array in the described drift groove 3; Described detent 4 extends to the inside of drift groove 3 from the port of drift groove 3, be provided with three corners between the two ends of this detent 4; Described three corners all are rectangular in shape; Described drift 2 is provided with cylinder fixture block 6; Four location dops 6 that match with detent 4 of annular array on the described cylinder fixture block 6; During installation, drift 2 is fixed in the detent 4 in the punch holder 1 by location dop 6.Structural design by detent, on original punch structure, after being damaged, drift can disassemble, only need to change the forward part of drift and get final product, and need not integral body change, do not affect again drift effect in use, solved the problem that integral body was scrapped after drift damaged, provide cost savings and resource the rate that takes full advantage of of the material of raising.
Below only be concrete exemplary applications of the present utility model, protection domain of the present 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.
