Abstract

The utility model relates to an auto parts proximal edge symmetry hole flanging mould, including setting up in die (17) of cope match -plate pattern (1), set up in the terrace die subassembly of lower bolster (6), connect the guide pillar subassembly 4 of cope match -plate pattern (1) and lower bolster 6, still including setting up pushing down on lower bolster 6 flitch (5), set up finished piece (10) in pushing down flitch 5, what be connected with cope match -plate pattern (1) leads positive module (2), inlay in leading positive module (2) die (17), be provided with on lower bolster (6) and prevent that terrace die subassembly (11) are because of the cracked slide wedge mechanism of turn -ups atress. It is unusual that this mould has reduced the production halts and the product quality that cause because of the fracture of hole flanging terrace die, has prolonged the life -span of proximal edge symmetry hole flanging terrace die, has improved comprehensive productivity effect.

Description

The symmetrical plunging die of a kind of auto parts near side (ns)
Technical field
The utility model belongs to auto parts tooling device field, is specially the symmetrical plunging die of a kind of auto parts near side (ns), is applied to hole flanging class mould.
Background technology
Two hole flangings of part as shown in Figure 1, the special character of itself and other hole flanging product is that 2 square holes and U-shaped flange root are very near, and frock turns over U-shaped after realizing first hole flanging without space; 2 hole flangings are coaxial and hole flanging is in outward direction, and distance is only 30mm.Traditional plunging die is the direct hole-crimped forming of punch and matrix, but punch must be placed in U-shaped by this parts modeling, because U-shaped space is little, and hole flanging height stroke of need stepping down, for ensureing that workpiece is put into, it is smooth and easy to take out, the shaping force part of punch must hang and thickness is partially thin, therefore easily causes Punch rupture, affects the punch life-span.
Utility model content
The purpose of this utility model is to provide a kind of auto parts near side (ns) symmetrical plunging die, this mould reduce because of Burring Punch rupture the production interruption that causes and product quality abnormal, extend the life-span of near side (ns) symmetry Burring Punch, improve comprehensive productivity effect.
For solving the problems of the technologies described above, the utility model comprises product, be arranged at the die of cope match-plate pattern, be arranged at the punch assemblies of lower bolster, connect the Guide column component of cope match-plate pattern and lower bolster, be arranged at the lower holding pad on lower bolster, the correcting module be connected with cope match-plate pattern, described female die embedding, in correcting module, described lower bolster is provided with the Wedge mechanism preventing punch assemblies from rupturing because flange is stressed.
Further, Wedge mechanism comprises drive block, slide block, back-up block, drive block backrest, the first spring, and described back-up block, slide block, drive block, drive block backrest, the first spring connect successively.During work, drive skid when drive block is descending, slide block drives back-up block upward sliding, supports punch assemblies, thus plays the effect preventing punch assemblies from rupturing because flange is stressed.
Further, the second spring for making back-up block return is provided with bottom described lower bolster.
Again further, the 3rd spring for locating product is provided with bottom described lower holding pad.
Preferably, the diameter of described back-up block is less than the aperture before product hole flanging.
More preferably, feet is provided with bottom described lower bolster.
The symmetrical plunging die of a kind of auto parts near side (ns) of the utility model, by the Wedge mechanism that lower bolster is arranged, plays the life-span of the symmetrical Burring Punch of the prolonged action preventing punch assemblies from rupturing because flange is stressed near side (ns) in process of production; After being terminated turning over mould by the second spring arranged bottom lower bolster, ensure the descending return of back-up block; By the 3rd spring arranged bottom lower holding pad, make product correcting locate and compress, product hole flanging can be allowed after production terminates accurately to depart from punch assemblies; The design of mould ensures production product quality, improves comprehensive productivity effect.
