Abstract

The utility model discloses a hole flanging punching mold, which comprises a punching needle, a material discharge plate and a female mold, wherein an element to be processed is placed between the material discharge plate and the female mold, a punching head of the punching needle corresponds to the hole flanging position on the element to be processed, and the hole flanging position on the female mold corresponding to the element to be processed is provided with a material falling hole, wherein the punching head of the punching needle comprises a body part and an end part, the diameter of the end part is smaller than that of the body part, an arc-shaped transition region is arranged from the end part to the body part, and the diameter of the material falling hole arranged on the female mold is greater than that of the body part of the punching head, and is the same as the diameter of the hole flanging external outline formed after the element to be processed is punched. Compared with the prior art, the utility model can complete the hole flanging processing in one step through the improvement on the punching mold, so the production period of parts is shortened, and the production efficiency is improved.

Description

A kind of hole flanging stamping die
Technical field the utility model relates to a kind of metalwork processing mold, relates in particular to a kind of hole flanging stamping die.
The diel of making plate hole flanging comprises that towards pin 1, stripper 2 and die 3 work piece 4 places between stripper 2 and the die 3, as shown in Figure 1 by carrying out punching press towards 1 pair of work piece of pin 4 in the background technology prior art.Described drift 01 towards pin 1 is columniform cab-over design, is provided with material-dropping hole 31 with drift 01 corresponding position on the die 3.Because the diameter of material-dropping hole 31 is close with end 02 diameter of drift 01, the spacing between drift 01 and the material-dropping hole 31 is little, and the punching that forms on work piece 4 towards pin 1 is columniform through hole.Therefore, also need after the punching step could on work piece 4, form hole flanging 41 through the hole flanging operation.
The summary of the invention the purpose of this utility model provides an a kind of punching press can form hole flanging on plate hole flanging stamping die that passes through.
For achieving the above object, the utility model comprises towards pin, stripper and die, work piece is arranged between stripper and the die, towards the drift of pin corresponding to the hole flanging position on the work piece, hole flanging position corresponding to work piece on the die is provided with material-dropping hole, wherein, described drift towards pin comprises main part and end, the diameter of end is less than the diameter of main part, from the end to the main part, be provided with the arc-shaped transition district, the diameter of the material-dropping hole on the described die is greater than the diameter of punch body part, and consistent with the hole flanging outline diameter that forms after the work piece punching press.
Adopt structure of the present utility model, in the process of punching press, drift towards pin forms perforation earlier on work piece, along with advancing towards pin, the cambered surface transition region of drift is pushed the diameter of boring a hole material on every side and enlarging perforation, material around the work piece perforation is to the direction projection that is stamped, and last, work piece forms hole flanging by the main part of drift and the material-dropping hole co-extruded of die.Compared with prior art, the utility model can be finished the processing of hole flanging, thereby shorten the production cycle of part by the improvement to stamping die in a step, improved production efficiency.
Description of drawings is described in further detail the utility model below in conjunction with the drawings and specific embodiments:
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present utility model;
The hole flanging schematic diagram of Fig. 3 for forming after the work piece punching press.
The specific embodiment is shown in Fig. 2 or 3, the utility model comprises towards pin 1, stripper 2 and die 3, work piece 4 is arranged between stripper 2 and the die 3, towards the drift 11 of pin 1 corresponding to 41 positions of the hole flanging on the work piece 4, hole flanging 41 positions corresponding to work piece 4 on the die 3 are provided with material-dropping hole 31, described drift 11 towards pin 1 comprises main part 12 and end 13, the diameter of end 13 is less than the diameter of main part 12,13 are provided with cambered surface transition region 14 to main part 12 from the end, the diameter of the material-dropping hole 31 on the described die 3 is greater than the diameter of drift 11 main parts 12, and consistent with hole flanging 41 outlines 42 diameters that form after work piece 4 punching presses.

Claims (1)
