Description

A kind of hole flanging mold improving structure

Technical field

The utility model belongs to stamping die technology, especially a kind of hole flanging mold for improving structure.

Background technique

Zero is generally relied on if not having available fabrication hole to position on the part of processing for traditional hole flanging mold The shape of part positions, and just finally determines, turns over after needing repetition test due to the appearance profile of part in die manufacture Punch die exploitation and composition can not synchronize, and cause the development cycle long；And homogeneity of product is poor when producing in batches, product geometric dimension It is unstable.

Summary of the invention

In order to overcome above-mentioned prior art defect, the utility model proposes a kind of hole flanging molds for improving structure, can not It positions, is directly positioned using hole to be turned over, flanging upward hole by the shape of product, solve part positions unstable ask Topic, mold without waiting for remanufacturing hole flanging mold after appearance profile is ordered for a trial when manufacturing, while effective solution uses mold The problem of homogeneity of product difference when punching production.

For this purpose, the technical solution of the utility model are as follows: a kind of hole flanging mold for improving structure, including upper plate, lower plate, Burring Punch, hole flanging cavity plate, lower die elastic ejection device, upper mold elastic ejector pin, guide post, guide sleeve, guide post, guide sleeve are separately fixed at down On bottom plate, upper plate, guide post, guide sleeve constitute guidance set, it is characterised in that: Burring Punch is fixed on lower plate, and hole flanging is recessed Mould is fixed on upper plate, and lower die backing-out punch is sleeved on Burring Punch, and upper mold elastic ejector pin is mounted on the following table of hole flanging cavity plate On face；

The head of Burring Punch is provided with positioning step axle journal, and positioning step axle journal directly treats the hole positioning turned over.

The beneficial effects of the utility model are: directly part being placed on the upper surface of lower die elastic ejection device when hole flanging, being turned over The positioning step axle journal of hole punch-pin is positioned using hole to be turned over, and upper mold downlink contacts with lower die elastic ejection device, part is compressed, Flanging upward hole；After hole flanging, part is exited Burring Punch by lower die elastic ejection device, and upper mold elastic ejector pin, which exits part, to be turned over Hole cavity plate；The utility model is positioned not against the shape of product, is directly positioned using hole to be turned over, and flanging upward hole solves zero The unstable problem of the positioning of part, mold without waiting for remanufacturing hole flanging mold after appearance profile is ordered for a trial, have simultaneously when manufacturing Homogeneity of product when solving the problems, such as to produce using mould punching of effect is poor.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

In the following, in conjunction with attached drawing, the utility model is described in further detail.

A kind of hole flanging mold of improvement structure as shown in Figure 1, including upper plate 1, lower plate 10, Burring Punch 8, hole flanging Cavity plate 2, lower die elastic ejection device 9, upper mold elastic ejector pin 3, guide post 6, guide sleeve 5, guide post 6, guide sleeve 5 be separately fixed at lower plate, On upper plate, guide post 5, guide sleeve 5 constitute guidance set, Burring Punch 8 is fixed on lower plate 10, and hole flanging cavity plate 2 is fixed on On bottom plate 1, lower die elastic ejection device is sleeved on Burring Punch 8, and upper mold elastic ejector pin 3 is mounted on the lower surface of hole flanging cavity plate On；The head of Burring Punch is provided with positioning step axle journal 8-1, and positioning step axle journal 8-1 directly treats the hole positioning turned over.

As shown in Figure 1, setting of the upper mold elastic ejector pin 3 on cavity plate is existing conventional techniques, in the following table of hole flanging cavity plate 2 It is uniformly distributed along the circumference on face equipped with multiple holes, elastic ejector pin 3 is made of spring, ejector pin, and spring, ejector pin are successively mounted in pilot hole.

As shown in Figure 1, lower die elastic ejection device 9 is existing conventional techniques, including discharging ring, multiple unloading bolts 7, bullet Spring, material screw 7 pass through the counterbore of discharging ring, and multiple unloading bolts 7 are simultaneously connected on lower plate 10, and spring pocket is mounted in unloading bolt 7, discharging ring is flexibly supported.

As shown in Figure 1, the setting of guide post 6, guide sleeve 5 is existing conventional techniques, it is not unfolded to describe herein.

Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to In the utility model range claimed.
