Description

A kind of automobile rear floor crossbeam component die
Technical field
The present invention relates to a kind of auto parts and components production mould, especially relate to a kind of automobile rear floor crossbeam component die.
Background technology
Back floor crossmember is the parts that are welded on the automobile rear floor, and the strength and stiffness that it makes time spent reinforcement automobile rear floor improve reversing and mode of vehicle body.At present, the mould of this part is divided into punching, 2 operations of cutting edge, and wants two jig frequencies during production, needs a large amount of operating personnel, the manufacturing cost height, and the manufacturing cycle is long, and production efficiency is not high.As power source, spring or nitrogen spring all can have the requirement of normal damage and periodic replacement to existing patrix eccentric swage with spring or nitrogen spring, and maintenance and renewal cost in the production process promote significantly.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of production cost automobile rear floor crossbeam component die low, easy to maintenance for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of automobile rear floor crossbeam component die, comprise counterdie and patrix, described counterdie comprises die shoe, lower mold core and ejector, described lower mold core and ejector are arranged on the die shoe, set gradually trimming and piercing die punch and flanging and restriking punch on the described lower mold core;
Described patrix comprises that upper bolster, upper mold core, patrix are inserted, patrix eccentric swage and upper ejector pin, described upper mold core is arranged on the upper bolster below, set gradually trimming and piercing die die and flanging and restriking die on the described upper mold core, described upper ejector pin is arranged on the top of upper bolster.
Described trimming and piercing die punch is corresponding with the trimming and piercing die die, and described flanging and restriking punch is corresponding with the flanging and restriking die.
Described upper ejector pin arranges 4-8, disperses to be arranged on the top of upper bolster.
Compared with prior art, the present invention has the following advantages:
1) production cost is low: with punching side blow hole, 2 combination of actions of side side cut side shaping together, just become continuous combination die, two traditional achievable parts of operation are finished with a secondary mould, a jig frequency has been omitted in the centre, reduce production cost, improved the stability that part is produced;
2) easy to maintenance, safe and reliable: as to use upper push rod structure to upgrade the expensive traditional mode that last eccentric swage uses spring or nitrogen spring, convenient for maintaining, do not need to check or replacing binder power source before each the production, saved the expense of the maintenance of spring or nitrogen spring and periodic replacement.
Description of drawings
Fig. 1 is the structural representation of mould of the present invention.
Among the figure, 1 is die shoe, and 2 is the trimming and piercing die punch, and 3 is the trimming and piercing die die, and 4 is the flanging and restriking punch, and 5 is the flanging and restriking die, and 6 is upper ejector pin, and 7 is upper bolster.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, a kind of automobile rear floor crossbeam component die comprises counterdie and patrix, and counterdie comprises die shoe 1, lower mold core and ejector, and lower mold core and ejector are arranged on the die shoe, set gradually trimming and piercing die punch 2 and flanging and restriking punch 4 on the lower mold core; Patrix comprises that upper bolster 7, upper mold core, patrix are inserted, patrix eccentric swage and upper ejector pin 6, upper mold core is arranged on the upper bolster below, set gradually trimming and piercing die die 3 and flanging and restriking die 5 on the upper mold core, trimming and piercing die punch 2 is corresponding with trimming and piercing die die 3, and flanging and restriking punch 4 is corresponding with flanging and restriking die 5.Upper ejector pin 6 arranges 4, disperses to be arranged on the top of upper bolster 7.
Above-mentioned automobile rear floor crossbeam component die operation principle is, when press is depressed with specified pressure, by the patrix eccentric swage part to be processed is compressed, do punching side blow hole, side side cut side shaping action by trimming and piercing die punch 2 and trimming and piercing die die 3, flanging and restriking punch 4 respectively with the working portion of 5 two stations of flanging and restriking die then, a punching press action is covered, and press rises the back ejector with part jack-up to be processed.
