Abstract
The invention belongs to cold punching technology field, and in particular to a kind of hole flanging cold punching technology, comprise the following steps：（1）Hole flanging：The steel plate for needing to process is placed on hole flanging cavity plate, using the collective effect of hole flanging upper punch and hole flanging low punch, steel plate extruded, it is bent along hole flanging cavity plate upper groove, and the part laminating groove outer wall for making to be bent over, realize hole flanging；（2）Rush waste material：Using the useless drift of punching and the useless cavity plate of punching to step（1）The waste material formed between middle hole flanging upper punch and hole flanging low punch is punched out.The advantage of the invention is that：Hole flanging is directly carried out, by hole flanging upper punch and the collective effect of hole flanging low punch with fillet, then waste material punching is carried out, ensure that the precision of hole flanging, hole flanging oral area cracking, the thinning defect such as serious are prevented, while the operating procedure of the hole flanging simplified.
Description
Technical field
The present invention relates to a kind of hole flanging cold punching technology, a hole flanging is specifically processed on steel plate, belongs to cold punching
Press technical field.
Background technology
Hole flanging is the processing method for stamping for the peritreme on sheet material being translated into using mould vertical edge.It is to embark on journey one of flange in mould
Kind, the plastic deformation process belonged in punching press basic working procedure is mainly used in making the part equipped with other parts, or in order to carry
The rigidity of high part, and the given shape gone out under adding.Profit in this way can be complex with machining shape and had good firm
The three-dimensional part of degree and proportional space shape, can also be used as control rupture or the means of wrinkle in large-scale metal plate forming.
In the prior art, hole flanging manufacturing process is first to rush pre- hole to carry out drawing again, it is translated into setting along certain curve
Straight flange realizes hole flanging, and this technique can cause hole flanging oral area to ftracture, and hole flanging is highly non-uniform, the thinning defect such as serious of hole flanging oral area.
The content of the invention
It is an object of the invention to overcome the shortcoming of traditional handicraft, so as to provide a kind of new processing technology, it ensure that
The precision of hole flanging, prevents hole flanging oral area cracking, the thinning defect such as serious.
According to technical scheme, the hole flanging cold punching technology comprises the following steps：
（1）Hole flanging：The steel plate for needing to process is placed on hole flanging cavity plate, the common of hole flanging upper punch and hole flanging low punch is utilized
Effect, is extruded steel plate, it is bent along hole flanging cavity plate upper groove, and the part that is bent over is fitted groove outer wall, reality
Existing hole flanging；
（2）Rush waste material：Using the useless drift of punching and the useless cavity plate of punching to step（1）Formed between middle hole flanging upper punch and hole flanging low punch
Waste material be punched out.
Further, hole flanging upper punch and hole flanging the low punch head has fillet.
Compared with prior art, the present invention has advantages below：Hole flanging is directly carried out, by the hole flanging upper punch with fillet
With the collective effect of hole flanging low punch, then waste material punching is carried out, ensure that the precision of hole flanging, prevented hole flanging oral area cracking, become
The thin defect such as serious, while the operating procedure of the hole flanging simplified.
Brief description of the drawings
Fig. 1 is hole flanging schematic diagram of the present invention.
Fig. 2 is that the present invention rushes waste material schematic diagram.
Description of reference numerals：1- hole flangings upper punch, 2- hole flangings cavity plate, 3- hole flangings low punch, the useless drift of 4- punchings, 5- punchings are useless recessed
Mould.
Embodiment
With reference to specific drawings and examples, the invention will be further described.
The present invention comprises the following steps：
（1）Hole flanging：As shown in Figure 1, it would be desirable to which the steel plate of processing is placed on hole flanging cavity plate 2, hole flanging upper punch 1 and hole flanging are utilized
The collective effect of low punch 2, is extruded steel plate, it is bent along the upper groove of hole flanging cavity plate 2, and pastes the part being bent over
Groove outer wall is closed, hole flanging is realized.Hole flanging upper punch 1 and the head of hole flanging low punch 3 have fillet, preferably avoid hole flanging oral area
Cracking, the thinning defect such as serious.
（2）Rush waste material：It can not possibly realize because hole flanging upper punch 1 and hole flanging low punch 3 are acted on and break through steel plate completely, at it
Between can form waste material, meanwhile, can also exist between the fillet part of hole flanging upper punch 1 and hole flanging low punch 3 and hole flanging inwall
Waste material, accordingly, it would be desirable to carry out waste material punching.As shown in Fig. 2 using the useless drift 4 of punching and the useless cavity plate 5 of punching to step（1）Middle hole flanging
The waste material formed between upper punch 1 and hole flanging low punch 3 is punched out.
The present invention directly carries out hole flanging, by hole flanging upper punch and the collective effect of hole flanging low punch with fillet, then enters
Row waste material is punched, and ensure that the precision of hole flanging, hole flanging oral area cracking, the thinning defect such as serious is prevented, while the hole flanging simplified
Operating procedure.
Claims (2)
1. a kind of hole flanging cold punching technology, it is characterised in that comprise the following steps：
（1）Hole flanging：The steel plate for needing to process is placed on hole flanging cavity plate, the common of hole flanging upper punch and hole flanging low punch is utilized
Effect, is extruded steel plate, it is bent along hole flanging cavity plate upper groove, and the part that is bent over is fitted groove outer wall, reality
Existing hole flanging；
（2）Rush waste material：Using the useless drift of punching and the useless cavity plate of punching to step（1）Formed between middle hole flanging upper punch and hole flanging low punch
