Description

Truck dashboard apron limit processing mold

Technical field

The utility model relates to a kind of mould, the dedicated processing mould on especially a kind of truck dashboard apron limit.

Background technology

The truck dashboard is to be positioned at the parts that the automotive wheel top is used to keep off mud, its formation comprises symmetrically arranged two apron limits and the baffle plate that is arranged at two ends, apron limit, wherein the apron limit is for totally being the U type, and cross section is also made for the cold reduced sheet of U-shaped, plays a part to connect and supporting baffle.

Stamping forming processes is adopted on the apron limit usually, twice moulding usually adopted on a pair of apron of processing limit in its traditional moulding process, the pattern of single-piece punching press, adopt this molding mode, it needs many molds, and a pair of apron limit symmetry after the moulding is not high, causes the difficulty of welding of dashboard subsequent combination and assembly technology.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art and a kind of composite die that can a pair of apron of one-shot forming limit is provided, and it can make a pair of apron limit symmetry after the moulding improve greatly.

Adopted following technical scheme for solving the problems of the technologies described above the utility model:

A kind of truck dashboard apron limit processing mold, comprise counterdie and face the patrix that counterdie is provided with, wherein said counterdie comprises the base plate of strip, be arranged at the die on the base plate, the length baffle plate, the width baffle plate, described die is a strip, its upper surface by and institute's processing apron limit profile U-shaped cambered surface of mating, the length baffle plate is arranged at die upper surface both sides along its length, the width baffle plate is arranged at the width both sides, also be provided with a jet-bedding on the die upper surface center line along its length, side bottom the length of jet-bedding and the institute's apron edge lengths of the process coupling, jet-bedding is provided with a waste material towards the counterdie appearance along the jet-bedding direction and portals; Described patrix comprises the pressing plate that underside shape is consistent with the die upper surface, punch with the jet-bedding form fit, be fixedly arranged on the support of the support pressing plate of pressing plate top, die shank, wherein on pressing plate center line along its length, have a groove, punch is arranged in the groove, the support inside of punch top also is provided with elastomeric element, described elastomeric element can be made by the rubber elastomeric material, play impulse force between alleviation punch and the bracing frame, described die shank one end is fixed in the punch upper surface middle part, the other end links to each other with dynamical system after passing elastomeric element and support successively movably.

When using the utility model punching press, to be positioned over the counterdie upper surface through the workpiece germule that blanking process forms earlier, limit its slip along its length by the length baffle plate, the width baffle plate limits the slip of its broad ways, patrix presses down during punching press, the workpiece germule is struck out required form, simultaneously die shank continues to press down the punch that makes in the patrix and enters in the jet-bedding in the counterdie, by force the workpiece germule behind the first one-step forming is cut off from center line, promptly obtain symmetrical a pair of apron limit, so only need wash out less waste material, just can obtain a pair of apron limit, the waste material of going out can be discharged from waste material portals so that punching press continuously.

The beneficial effects of the utility model are:

Now than in prior art, the utility model only adopts once symmetrical punching press, and shear forming can obtain a pair of apron limit, promptly is to adopt symmetrical punching press before workpiece is sheared, so its symmetry height is beneficial to that the dashboard subsequent combination is welded and the carrying out of assembly technology; Simultaneously improved stock utilization, reduced processing step and mould and saved cost owing to waste material is few.
