The requirement of the parameters such as the net shape size of part or shallow recessing part.At present, beam piece or shallow recessing part carry out in the production process
When positioning deburring, using the moulding face of drawn component itself and the profile of blank terminated line, set in the mode surrounding of deburring station
Positioning tool, reaches the mesh of plate trimming process step positioning, but normal conditions, and plate can produce after beam piece and shallow recessing part drawing
Rebound, spacing positioning, positioning tool and plate are carried out by the profile and moulding face of itself in deburring mode surrounding using positioning tool
The termination line profile of embryo material part is point contact mode, and positioning accuracy is poor, and positioning is unstable, and play, offset easily occurs, causes plate
The relative position degree in the profile of part deburring and hole and moulding face produces offset, the yield requirement that product does not reach.
Utility model content
The purpose of this utility model is to provide a kind of drawing die, with solve in the prior art drawing plate trimming orientation when
Positioned by the point contact mode of positioning tool and the termination line profile of plate embryo material part, play easily occurs, deviates and leads
The profile of plate deburring and the relative position degree in hole and moulding face is caused to produce offset, the technology for the yield requirement that product does not reach
Problem.
To achieve the above object, the technical solution of the utility model is：
A kind of drawing die of the utility model, for drawing sheet forming to be molded, including upper die and lower die, it is described on
Upper cores are provided with the upper mold seat of mould, are provided with the die holder of the lower die and the matched lower mode of the upper cores, institute
State lower mode periphery and be provided with blank holder, what the blank holder can be moved up and down relative to the lower mode is installed on the lower die
On seat, at least one circular flanging die is further included, the flanging die is fixedly installed on the die holder of the lower die, and
The blank holder is run through in upper end, and the end face part of the flanging die is overlapping with the drawing plate member edge, is set in the upper mold
It is equipped with the flange cavity plate coordinated with the flanging die.
Further improvement lies in that the flanging die is two, two flanging dies are distributed in diagonal way
On the blank holder.
Further improvement lies in that the flanging die end face is provided with semicircle step, low of the semicircle step
Terrace and the joint face of high step surface and the edge matching of the drawing plate, for positioning the drawing plate.
Further improvement lies in that two flanging dies be distributed in the drawing plate walk to expect it is few cornerwise described
On blank holder.
As a result of above technical scheme, make it have following beneficial effect is the utility model：
By setting the circular flange mold of a male-female engagement between upper mold and lower die, the flanging die of flange mold is arranged on
Die holder, and run through blank holder, the flange cavity plate of flange mold is corresponding to be arranged on upper mold seat, during punching press drawing, drawing plate
Edge is clamped between the blank holder of upper die and lower die, and end face part and the drawing plate of flanging die are walked to expect few side
Edge is overlapping, and after flanging die is bonded completely with flange cavity plate, the edge of drawing plate is dug upwards, forms an arc surface, leads to
Positioning tool when crossing arc surface with positioning deburring cooperatively forms face and contacts, and can prevent drawing plate play on positioning deburring mode
And cause to position the problem of unstable, the deburring size of drawing plate and the precision in hole are greatly improved, in high-speed production, is ensured
The qualification rate of drawing plate.
