Abstract

The invention discloses a trimming and punching compound die for automobile sheet metal stampings. The trimming and punching compound die comprises an upper die base and a lower die base; guide posts and guide sleeves in sliding fit with each other are fixed between the upper die base and the lower die base; a male die base plate and a male die fixing plate are fixed in order on the lower end face of the upper die base; a trimming female die is fixed to the edge of the lower end face of the male die fixing plate, and four punching male die bases are fixed to the center of the lower end face of the male die fixing plate; a punching male die is fixed on the punching male die bases; a female die base plate and a female die fixing plate are fixed in order on the upper end face of the lower die base; the female die fixing plate is provided with a trimming male die and a punching female die; the trimming male die matches with the trimming female die; the punching female die matches with the punching male die. The trimming and punching compound die has the advantages that a trimming step and a punching step are finished together, the process is simplified, fewer devices are used, floor area is reduced and work efficiency is improved.

Description

A kind of edge-cutting and hole-punching composite die for plates of automobile stamping parts
Technical field
The present invention relates to a kind of edge-cutting and hole-punching composite die for plates of automobile stamping parts.
Background technology
The operation that current automobile production metal plate punching part generally adopts is single operations such as blanking, shaping, punching, bending, although it is relatively simple to do mould structure like this, but have that production efficiency is low, processing cost is high, personnel increase, and the shortcoming such as part quality risk of instability is large.
Summary of the invention
Object of the present invention, provides a kind of edge-cutting and hole-punching composite die for plates of automobile stamping parts exactly in order to solve the problem, complete together with trimming operation being merged with punching operation.
The object of the present invention is achieved like this:
A kind of edge-cutting and hole-punching composite die for plates of automobile stamping parts of the present invention, comprise upper bolster and die shoe, the guide pillar be mutually slidably matched is fixed with respectively between described upper bolster and die shoe, guide pin bushing, the lower surface of described upper bolster is fixed with convex mould pad successively, punch retainer, the edge of described punch retainer lower surface is fixed with trim die, center is fixed with four punching convex die holders, described punching convex die holder is fixed with piercing punch, the upper surface of described die shoe is fixed with die backing plate successively, die block, described die block is respectively equipped with the trimming punch matched with described trim die and the punching concave die matched with described piercing punch.
Above-mentioned a kind of edge-cutting and hole-punching composite die for plates of automobile stamping parts, wherein, is fixed with the upper and lower limited block controlling described trim die and trimming punch and contact respectively between described upper bolster and die shoe.
Above-mentioned a kind of edge-cutting and hole-punching composite die for plates of automobile stamping parts, wherein, the distance of described upper limit position block and lower position block close to and the distance be less than between described trim die and trimming punch.
The present invention completes together with trimming operation being merged with punching operation, simplifies operation, decreases equipment and floor space, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the upward view of upper bolster in the present invention;
Fig. 3 is the top view of die shoe in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1 to Fig. 3, the present invention is used for the edge-cutting and hole-punching composite die of plates of automobile stamping parts, comprise upper bolster 1 and die shoe 2, the guide pillar 13 be mutually slidably matched is fixed with respectively between upper bolster 1 and die shoe 2, guide pin bushing 23, wherein, guide pillar 13 is located on the lower surface of upper bolster 1, guide pin bushing is located on the upper surface of die shoe 2, the lower surface of upper bolster 1 is fixed with convex mould pad 11 successively, punch retainer 12, the edge of punch retainer 12 lower surface is fixed with trim die 16, center is fixed with four punching convex die holders 14, punching convex die holder 14 is fixed with piercing punch, the upper surface of die shoe 2 is fixed with die backing plate 21 successively, die block 22, die block 22 is respectively equipped with the trimming punch 26 matched with trim die 16 and the punching concave die 24 matched with piercing punch.
Be fixed with respectively between upper bolster 1 and die shoe 2 and control upper limit position block 15 that trim die 16 and trimming punch 26 contact and lower position block 25.The distance of upper limit position block 15 and lower position block 25 close to and the distance be less than between trim die 16 and trimming punch 26, in the course of the work, due to the restriction of upper limit position block 15 and lower position block 25, make the cutting edge of trim die 16 and trimming punch 26 avoid encountering, thus considerably increase the service life of trim die 16 and trimming punch 26.
To be formed with trim die 16 after shearing force completes trimming when trimming punch 26 moves downward, continue to move downward, make workpiece and piercing punch form shear knife to complete punching.Complete together with thus trimming operation being merged with punching operation.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present invention, should be limited by each claim.
