Abstract

The utility model discloses a drawing die for a first transverse beam of an automobile top cover. The drawing die comprises an upper die holder, a lower die holder, a guide sleeve, a guide post, a female die, a male die and a drawing ring, wherein the male die, the female die and the drawing ring are matched with each other, so that the shape of the first transverse beam of the automobile top cover is formed. A product manufactured with the drawing die has high consistence, and the physical property and rigidity of a reinforcing plate are enhanced under the processing reinforcing action of plastic deformation of the die in a drawing process.

Description

The automobile top-cap first crossbeam drawing die

Technical field

The utility model relates to a kind of drawing die, particularly a kind of automobile top-cap first crossbeam drawing die.

Background technology

Along with the high speed development of economic technology and the raising of living standards of the people, automobile has become the vehicles that could not lack in people's life, and the security performance of automobile also becomes important one side simultaneously, has caused people's attention.Covering for roofs is the cover plate of car body top.For the global stiffness of body of a motor car, top cover is not an important components very, and this also is the reason that allows on covering for roofs, to offer the skylight.For the accident-free vehicle top cover also should have certain intensity and rigidity, the general buttress brace that under top cover, increases some.The quality of security performance has become weighs a good and bad major criterion of automobile, strengthens the vehicle body collision performance, and body distortion is a key index that improves the vehicle passive safety performance to member's injury after avoiding colliding.Therefore, the crossbeam of the automobile top-cap particular importance that seems.

Traditional automobile top-cap crossbeam can adopt the direct welding fabrication of steel pipe, though very convenient like this, reduced the expense of the each side such as mould that are used to make the punching press inner panel, reduced cost; But existing tubing cutting of this employing and welding are used as bracing piece; The integraty of its intensity, rigidity and vehicle body does not utilize crossbeam effective of mould punching press (work strengthening); Adopt the crossbeam of steel pipe to strengthen the weight of vehicle body in addition, be unfavorable for lightweight and increasing the weight of energy consumption.

The utility model content

The purpose of the utility model is to overcome the deficiency of prior art and provides the good automobile top-cap of a kind of consistency of product that obtains the first crossbeam drawing die.

The purpose of the utility model is achieved through following technical proposals:

A kind of automobile top-cap first crossbeam drawing die comprises upper bolster, die shoe, guide pin bushing, guide pillar, die, punch and blank holder, and said punch, said die and said blank holder complement each other to form the shape of automobile top-cap first crossbeam.

In the utility model, said die is fixed on the said die shoe, and said punch is fixed on the upper bolster, is respectively equipped with corresponding guide pillars and bushes on four jiaos of said upper bolster and die shoe.

Because adopt said structure, thereby can adopt drawing die to process, the consistency of product that obtains is fine, through the work strengthening effect that the plastic deformation in the mould drawing process produces, mechanical property, the rigidity of stiffener are improved.From mould structure, four jiaos of corresponding four pairs of guide pillars, guide pin bushings of upper bolster and die shoe play positioning action, and locating effect is obvious.

Fig. 3 is the structural representation of the utility model

The specific embodiment

Below in conjunction with accompanying drawing, specify the specific embodiment of the automobile top-cap first crossbeam drawing die.

Like Fig. 1,2, shown in 3; A kind of automobile top-cap first crossbeam drawing die; Comprise upper bolster 5, die shoe 1, guide pin bushing, guide pillar, die 4, punch 2 and blank holder 3, said punch 2, said die 4 and said blank holder 3 complement each other to form the shape of automobile top-cap first crossbeam.

In the utility model, said die 4 is fixed on the said die shoe 1, and said punch 2 is fixed on the upper bolster 5, is respectively equipped with corresponding guide pillars and bushes 6 on four jiaos of said upper bolster 5 and die shoe 1.

Punch 2 and die shoe 1 are in the same place through bolt, and die shoe 1 is fixed on through clamping screw on the last moved cross beam of forging press, and die 4 and upper bolster 5 are in the same place through bolt, and upper bolster 5 is fixed on the following moved cross beam of forging press through clamping screw.When mould is specifically worked, there is guide pillar guide pin bushing 6 to carry out correcting, guarantee dimensional accuracy of products.The punch that adopts the upside-down mounting drawing die and blank holder 3 are down, and die is last, and it uses single action press, and the liftout tank below the holding pad working pressure machine is through the required pressure-plate-force of push rod acquisition.

Claims

1. automobile top-cap first crossbeam drawing die; Comprise upper bolster, die shoe, guide pin bushing, guide pillar, die, punch and blank holder, it is characterized in that: said punch, said die and said blank holder complement each other to form the shape of automobile top-cap first crossbeam.

2. the automobile top-cap first crossbeam drawing die according to claim 1; It is characterized in that: said die is fixed on the said die shoe; Said punch is fixed on the upper bolster, is respectively equipped with corresponding guide pillars and bushes on four jiaos of said upper bolster and die shoe.
