Abstract

The invention relates to an automobile nut plate part die. The die comprises a lower die base (1) and an upper die base (8). The lower die base (1) is sequentially provided with a lower forming female die (5) and a lower piercing female die (9), and the upper die base (8) is sequentially provided with an upper die guide post (2), an upper die guide pin (3), an upper die locating pin (4), an upper forming male die (6) and an upper piercing male die (7). Compared with the prior art, the die disclosed by the invention has the advantages of low production cost, safety, reliability, high production efficiency and the like.

Description

A kind of automobile nutplate 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 nutplate component die.

Background technology

The automobile nutplate is for each parts on the automobile are fixed together, to guarantee traffic safety.At present, the molding procedure of automobile nutplate part generally comprises operations such as several stretchings, punching moulding, concrete steps normally are placed on automobile nutplate part to be processed in the mould, stretching, punching one by one, circulation is finished for several times, such method of operating is labor intensive not only, efficient is very low, and part easily causes distortion in the transmission course of each operation, cause the part status instability, the final products state difference, nut cylinder place out of plumb, rib-loop has the snaggletooth phenomenon, and scrappage is higher, and the maintenance load of mould is big.

Summary of the invention

Purpose of the present invention is exactly to provide the automobile nutplate that a kind of production cost is low, production efficiency is high component die 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 nutplate component die, comprise die shoe and upper bolster, be provided with compacted under die and following punching concave die on the described die shoe successively, be provided with the patrix guide pillar on the described upper bolster successively, the patrix pilot pin, the patrix alignment pin, last forming convax mould and last piercing punch, part to be processed is placed in the mould, by the patrix guide pillar, the patrix pilot pin, the patrix alignment pin is located it, then by the compacted under die, last forming convax mould, following punching concave die and last piercing punch are to its disposable punch forming.

Described compacted under die and last forming convax mould correspondence, described punching concave die and last piercing punch correspondence down.

Described compacted under die and last forming convax mould are provided with some groups, and compacted under die aperture and last forming convax mould diameter reduce successively gradually.

Described punching concave die down and last piercing punch are provided with some groups, and following punching concave die aperture and last punching convex mould diameter reduce successively gradually.

Compared with prior art, the present invention has the following advantages:

1) production cost is low: progressive die has fundamentally been saved personnel's outfit and the quantity of institute's use lathe;

2) safe and reliable: because of the process that does not need to transmit between each operation, so the distortion probability in the transmission course of part is reduced.

3) production efficiency height: a jig frequency is finished a complete part, compares several operations of usefulness of traditional mode and finishes a needed operation of part, and production efficiency promotes significantly.

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 patrix guide pillar, and 3 is the patrix pilot pin, and 4 is the patrix alignment pin, and 6 is last forming convax mould, and 5 is the compacted under die, and 7 is last piercing punch, and 8 is upper bolster, and 9 are following punching concave die.

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 nutplate component die, comprise die shoe 1 and upper bolster 8, be provided with compacted under die 5 and following punching concave die 9 on the die shoe 1 successively, be provided with patrix guide pillar 2, patrix pilot pin 3, patrix alignment pin 4 on the upper bolster 8 successively, go up forming convax mould 6 and last piercing punch 7.

Compacted under die 5 and last forming convax mould 6 correspondences can arrange the quantity of compacted under die 5 and last forming convax mould 6 according to the demand of actual nutplate quantity and diameter, arrange 6 groups in this example, and compacted under die 5 apertures and last forming convax mould 6 diameters reduce successively gradually.

Following punching concave die 9 and last piercing punch 7 correspondences can arrange the quantity of compacted under die 5 and last forming convax mould 6 according to the demand of actual nutplate quantity and diameter, are provided with 6 groups in this example, and following punching concave die 9 apertures and last piercing punch 7 diameters reduce successively gradually.

The motion principle of above-mentioned automobile nutplate component die is, part to be processed is placed in the mould, when depressing with specified pressure, press by patrix and counterdie part to be processed is compressed, position by patrix guide pillar 2, patrix pilot pin 3 and patrix alignment pin 4 correcting parts, then by compacted under die 5, last forming convax mould 6, following punching concave die 9 and needed technology everything of finishing of part of last piercing punch 7 beginnings, a punching press action is covered, press rises, and namely finishes a qualified part.
