Abstract

The utility model discloses a flanging and once molding punch without scrap generation, which belongs to an accessory of a punching die and particularly belongs to a punch. The flanging and once molding punch comprises a punching segment and a flanging segment and has the following key points: the punching segment is of a pointed tapered shape. The flanging once molding punch has the advantages of solving the problem of poor quality troubling punching and flanging process in a long time just by a small change on the prior art, and lowering the rejection rate.

Description

The flange one-shot forming does not have the waste material drift
Technical field
The utility model belongs to the accessory of diel, especially belongs to drift.
Background technology
In existing diel, the product sheet metal thickness is below 2 millimeters, and there are two kinds of production methods in the aperture at the flange below 5 millimeters; A kind of is the drift that is varied in size by two top end diameter, and subpunch pre-punched hole, back flange two procedures are come moulding, promptly 1. little drift punching and blanking → 2. big drift flange; 1 of every preface 1 mould; Accomplished by two procedures, production efficiency is low, and cost is high.Another kind of drift is as shown in Figure 1, is a flange moulding, but has waste material to produce; Its user mode is as shown in Figure 2, and it is that the big or small drift in last a kind of method is united two into one, and becomes punching section 11 (little drift) and is positioned at front end; Flange section 12 (big drift) is positioned at the back of punching section 11, and drift 1 is fixed on the fixed head 3, and part 5 is between stripper 4 and concave template 6; Drift 1 processes at one time punching, flange two procedures, has improved production efficiency, but because waste material 7 volumes are little; In light weightly taken up by drift easily, part is produced impression, cause bad and scrap products.
Summary of the invention
The utility model purpose is to overcome the shortcoming that above-mentioned drift exists, and provides a kind of and can improve working (machining) efficiency, can guarantee that again the flange one-shot forming of product quality does not have the waste material drift.
The technical scheme that the utility model adopted is that a kind of flange one-shot forming does not have the waste material drift, and it comprises punching section, flange section, and its main points are that its punching section is a sharp cone distal.
The utility model is on the drift basis of an existing flange moulding, to improve, and makes the punching section into sharp cone distal by the small cylindrical that end face is arranged, and no waste material had both improved working (machining) efficiency, can guarantee product quality again.
The advantage of the utility model is changed little to prior art, but solved the not high problem of long-term puzzlement piercing and flanging procedure quality, has reduced percent defective.

Fig. 4 is the user mode sketch map of the utility model
Wherein: 1 drift, 11 punching sections, 12 flange sections, 3 fixed heads, 4 strippers, 5 parts, 6 concave templates, 7 waste materials.
The specific embodiment
Below in conjunction with view the utility model is carried out detailed description, following embodiment can make the professional and technical personnel more understand the utility model, but does not limit the utility model in any form.
Like Fig. 3, shown in Figure 4, a kind of flange one-shot forming does not have the waste material drift, and it comprises punching section 11, flange section 12; Its punching section 11 is a sharp cone distal; Add the man-hour drift and 1 be fixed on the fixed head 3, part 5 is fixed between stripper 4 and the concave template 6, and drift 1 processes at one time punching, flange two procedures; Improved production efficiency, it is identical with prior art that all the other do not state part.
