Abstract
The invention relates to a die for a lower reinforcement plate part of an automobile A pillar, which comprises an upper die assembly and a lower die assembly. The upper die assembly comprises an upper die seat and an upper die core, an upper die insert and an upper die pressure device which are arranged on the upper die seat; the upper die core is positioned at the lower part of the upper die seat; the lower die assembly comprises a lower die seat and a lower die core and an ejector which are arranged on the lower die seat; the lower die core is positioned at the upper part of the lower die seat; the upper die assembly also comprises a plurality of upper ejector rods; the upper ejector rods pass through the upper die seat to be abutted against the top of the upper die core; the upper die core is provided with a trimming and punching female die, a flanging and sizing female die and a side punching female die; and the lower die core is provided with a trimming and punching male die, a flanging and sizing male die and a side punching male die. Compared with the prior art, three sets of dies are integrated into one set of die according to the invention; the production process is reduced; and due to adoption of the structure of the upper ejector rods, the die is convenient to maintain and a pressure power source does not need to be checked or replaced before production each time.
Description
Technical field
The present invention relates to a kind of mould, especially relate to a kind of mould for automobile A column lower reinforcing plate part.
Background technology
In prior art, processing is used for automobile A column lower reinforcing plate part and is divided into 3 operations, and use three auxiliary process moulds, need a large amount of operating personnel, manufacturing cost is high, and the manufacturing cycle is long, and production efficiency is not high.Eccentric swage spring or nitrogen spring are as power source, and spring or nitrogen spring all can have the maintenance in the normal requirement production process damaged and regularly replace and renewal cost significantly to promote.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of mould being used for automobile A column lower reinforcing plate part that the three process of trimming and piercing die, flanging and restriking and side punching can be carried out simultaneously is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of mould for automobile A column lower reinforcing plate part, comprise upper die component and lower mold assemblies, described upper die component comprises upper bolster and is arranged on the upper mold core on upper bolster, patrix insert, patrix eccentric swage, described upper mold core is positioned at the below of upper bolster, described lower mold assemblies comprises die shoe and the lower mold core that is arranged on die shoe and ejector, described lower mold core is positioned at the top of die shoe, described upper die component also comprises multiple upper ejector pin, this upper ejector pin is connected to the top of upper mold core through upper bolster, described upper mold core is provided with trimming and piercing die die, flanging and restriking die and side punching die, described lower mold core is provided with and trimming and piercing die die, the trimming and piercing die punch of flanging and restriking die and side punching die coupling, flanging and restriking punch and side punching punch.
Described trimming and piercing die die, flanging and restriking die and side punching die are successively set in upper mold core from left to right, described trimming and piercing die punch, flanging and restriking punch and side punching punch are corresponding with trimming and piercing die die, flanging and restriking die and side punching die respectively, are successively set on from left to right in lower mold core.
Described upper ejector pin is provided with 8 ~ 12.
Compared with prior art, the present invention has the following advantages:
1, production cost is low, omits two secondary moulds, and reduces two procedures, saves man power and material.
2, eccentric swage uses the structure of upper ejector pin, convenient for maintaining, does not need give birth to antenatal exaination at every turn or change binder power source.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of mould for automobile A column lower reinforcing plate part, comprises upper die component and lower mold assemblies.
Upper die component comprises upper bolster 9 and is arranged on upper mold core, patrix insert, patrix eccentric swage and 8 upper ejector pins 6 on upper bolster 9, upper mold core is positioned at the below of upper bolster 9, upper mold core is provided with trimming and piercing die die 3, flanging and restriking die 5 and side punching die 8 from left to right successively, and upper ejector pin 6 is connected to the top of upper mold core through upper bolster 9.
Lower mold assemblies comprises die shoe 1 and the lower mold core be arranged on die shoe 1 and ejector, lower mold core is positioned at the top of die shoe 1, lower mold core is provided with from left to right successively the trimming and piercing die punch 2, flanging and restriking punch 4 and the side punching punch 7 that mate with three kinds of dies.
The course of work of this mould is as follows: when press is depressed with specified pressure, tablet compresses by patrix eccentric swage, then trimming and piercing die, flanging and restriking, side punching action is done respectively by the working portion of three stations, a punching press action is covered, press rises, ejector, by part jack-up, takes out part.
Three width moulds are incorporated in a width mould by this mould, by the integration of mould, decrease production process, save man power and material, and adopt the upper eccentric swage of the structural change of upper ejector pin to use the high cost traditional mode of spring or nitrogen spring, save the expense of spring or nitrogen spring maintenance and periodic replacement.
