Abstract
A kind of handle body takes off inner edge drift, belong to forging field, comprise forging punches, described forging punches is integral type step drift, be divided into one-level drift and secondary drift, the body bottom of one-level drift and secondary drift is respectively arranged with one-level punch and secondary punch, punch body upper end is provided with flange, flange is connected with forging equipment, drift is processed into the shape with two-stage ram, drawing velocity can be improved, simultaneously, the raw material of punching recess under punching press as other forging can be continued to utilize, punching recess can not only be effectively utilized like this, and can also manufacturing cost be reduced, improve drawing velocity, enhance productivity.
Description
Technical field
The utility model relates to a kind of de-inner edge drift, and particularly a kind of handle body takes off inner edge drift, belongs to forging field.
Background technology
The application commercially of various types of forging is more and more extensive, and the Development Technology of forging also tends towards stability maturation, and forging company not only needs the quality ensureing product, enhances productivity, and effectively reduce production cost is also the most important thing simultaneously.Raw material many genus bar of forging or steel ingot, the punching recess on forging does not effectively utilize, and causes raw-material excess waste, increases production cost.Fig. 3 and Fig. 4 is side view and the top view of the drift of prior art.In figure, the hole that punch 31 is processed is less than the size of actual apertures, just can reach dimensional requirement, will cause the waste of punching recess part like this through continuing processing.How maximizedly can utilize raw material, be the key factor reducing production cost.
Summary of the invention
Effectively do not utilize for the punching recess on forging in prior art, cause raw-material excess waste, increase the problem of production cost, the utility model provides a kind of handle body to take off inner edge drift, its objective is the raw material of punching clout as other forging, reduce production cost, enhance productivity further.
The technical solution of the utility model is that a kind of handle body takes off inner edge drift, comprise forging punches, described forging punches is integral type step drift, be divided into one-level drift and secondary drift, the body bottom of one-level drift and secondary drift is respectively arranged with one-level punch and secondary punch, punch body upper end is provided with flange, flange is connected with forging equipment, described one-level punch and secondary punch are concentric circles, the diameter of one-level punch is less than the diameter of secondary punch, the diameter of described one-level punch and the diameter of secondary punch are greater than one-level drift body diameter and secondary drift body diameter respectively, described one-level drift body height is less than secondary drift body height.
The good effect that the utility model has is, drift is processed into two-stage ram, drawing velocity can be improved, simultaneously, the raw material of punching recess under punching press as other forging can be continued to utilize, can not only punching recess be effectively utilized like this, and can also manufacturing cost be reduced, improve drawing velocity, enhance productivity.

Detailed description of the invention
In order to better understand and carry out the technical solution of the utility model, provide embodiments more of the present utility model at this, these embodiments, in order to better explain technical scheme described in the utility model, are not formed any form restriction of the present utility model.
Lower just of the present utility model and technical scheme is described with reference to Fig. 1, Fig. 2, in figure, 10a: one-level punch, 10b: secondary punch, 11a: and drift body, 11b: secondary drift body, 12: fixing hole, 13: mounting flange, 31: punch, h1: one-level drift body height, h2: secondary drift body height.
A kind of handle body takes off inner edge drift, described forging punches is integrated step punch, be divided into one-level drift and secondary drift, one-level nose of punch is one-level punch 10a, secondary nose of punch is secondary punch 10b, punch body upper end is provided with flange 13, flange 13 utilizes fixing hole 12 to be connected with forging equipment, described one-level punch 10a and secondary punch 10b is concentric circles, the diameter of one-level punch 10a is less than the diameter of secondary punch 10b, the diameter of described one-level punch 10a and the diameter of secondary punch 10b are greater than one-level drift body diameter and secondary drift body diameter respectively, the height h1 of described one-level drift body is less than the height h2 of secondary drift body.
The utility model is by being processed into the shape with two-stage ram by a drift, drawing velocity can be improved, simultaneously, the raw material of punching recess under punching press as other forging can be continued to utilize, punching recess can not only be effectively utilized like this, and can also manufacturing cost be reduced, improve drawing velocity, enhance productivity.
After describing various specific embodiment of the present utility model above in detail, those of ordinary skill in the art should be well understood to, according to the various common practise of this area, can carry out various equivalent variations, equivalent replacement according to thinking of the present utility model or simply revise, these all should belong to the scope of technical solutions of the utility model.
