Abstract
The invention discloses a punch and belongs to the technical field of punching. The punch comprises a punch body of a cylindrical structure; the middle rear portion of the punch body is divided into a punch front section and a punch rear section through a step; an annular groove is formed in the step; a spring is arranged inside the groove; the punch front section is sleeved with the spring; an end cover is arranged on the upper portion of the spring. Compared with the prior art, as the spring is arranged on the groove in the punch body, a better buffering function can be achieved, and the spring does not shift; the punch structure is not simplex, punching of products of various specifications can be met, the actual production needs are met, the production cost of enterprises is reduced, and economic benefits are improved greatly.
Description
Technical field
The invention belongs to stamping technology field, particularly relate to a kind of drift.
Background technology
Drift is mounted in the metal parts in diel, is applied to and contacts with the direct of material, makes material generation deformation, cuts material.Current drift is direct punching press, not there is pooling feature, and punch end face does not have inclined-plane, after punching press easily there is burr in product edge, affects the quality of product, and punch structure intensity is lower simultaneously, easy damage, increase the production cost of enterprise, punch structure present in addition single, the needs of punching press products of different specifications can not be met.The problems referred to above, urgently to be resolved hurrily.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of drift.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of drift, comprise drift body, described drift body is cylindrical structural, it is characterized in that: drift body is divided into drift leading portion and drift back segment by step by the postmedian of described drift body, described step is provided with annular groove, in described groove, arranges spring, described spring housing is connected on described drift leading portion, and the top of described spring is provided with end cap.Such setting, because the groove on drift body is provided with spring, can play good cushioning effect, and spring can not be shifted.
In order to obtain better technique effect, further technological improvement also comprises, described drift leading portion is provided with the first square punch die and the second square punch die, the cross section of described first square punch die is greater than the cross section of described second square punch die, and the front end of described second square punch die is provided with conical head.Such setting, punch structure, not single, can meet the punching press of plurality of specifications product, meets and produces actual needs, reduce the production cost of enterprise, substantially increase economic benefit.
The invention has the beneficial effects as follows: because the groove on drift body is provided with spring, good cushioning effect can be played, and spring can not be shifted; Punch structure, not single, can meet the punching press of plurality of specifications product, meets and produces actual needs, reduce the production cost of enterprise, substantially increase economic benefit.
Accompanying drawing explanation
Fig. 1 is overall schematic of the present invention.
Fig. 2 is schematic top plan view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
Shown in Fig. 1 and Fig. 2, a kind of specific embodiment of drift of the present invention.A kind of drift, comprise drift body 1, described drift body 1 is cylindrical structural, drift body 1 is divided into drift leading portion 11 and drift back segment 12 by step 10 by the postmedian of described drift body 1, described step 10 is provided with annular groove 100, in described groove 100, arrange spring 2, described spring 2 is socketed on described drift leading portion 11, and the top of described spring 2 is provided with end cap 20.Such setting, because the groove on drift body is provided with spring, can play good cushioning effect, and spring can not be shifted.
Further, described drift leading portion 11 is provided with the first square punch die 121 and the second square punch die 122, the cross section of described first square punch die 121 is greater than the cross section of described second square punch die 122, and the front end of described second square punch die 122 is provided with conical head 13.Such setting, punch structure, not single, can meet the punching press of plurality of specifications product, meets and produces actual needs, reduce the production cost of enterprise, substantially increase economic benefit.
That more than enumerates is only specific embodiments of the invention, obviously, the invention is not restricted to above embodiment.All distortion that those of ordinary skill in the art can directly derive from content disclosed by the invention or associate, all should belong to protection scope of the present invention.
