Description

Pipe step stretching forming structure

Technical Field

The utility model relates to an automobile air bag body processing technology field especially relates to a body step stretch forming structure.

Background

Airbags have become almost standard equipment for automobiles, and the purpose of this system is to protect occupants from impact in a cushioned space by inflating the airbag quickly to reduce injury from impact in the event of a collision with an automobile by inflating the airbag within about 0.1 second. Be applied to the air bag body at present when carrying out stretch forming, pass through the manual processing operation more, extravagant manpower and materials, the shaping inefficiency, body production size is not accurate.

SUMMERY OF THE UTILITY MODEL

The purpose of the invention is as follows: the utility model discloses the low and not accurate technical problem of shaping of body production efficiency that will solve, the utility model provides a body step stretch forming structure.

The technical scheme is as follows: a tubular body step stretch-forming structure comprising: the lower die leg, the upper end of lower die leg is connected with the die holder, the backing plate is installed at the center of die holder, the upper end of backing plate is connected with the backplate, the upper end of backplate is connected with the backing plate, the die is installed to the upper end medial side of backing plate, the both sides of die are fixed with the briquetting, the body product is installed at the center of die, the lower push rod that stretches out backplate and backing plate is installed to the lower extreme of body product, the lower extreme of push rod is connected with nitrogen spring, nitrogen spring installs on the fixed plate of its lower extreme, the upside of die is equipped with the upper die base, the medial side lower extreme of upper die base is connected with the upper padding plate, the lower extreme of upper padding plate is connected with the punch holder, install the terrace die through the punch holder in the punch holder, the.

Preferably, the male die corresponds to the tubular product.

The utility model relates to a beneficial effect of body step stretch forming structure: the structure is simple, the die structure is simplified, the stamping pressure is reduced, the production efficiency of products is high, the forming size precision is high, and the production cost is low.

Drawings

Fig. 1 is a schematic structural view of the tube step stretch forming structure of the present invention.

Detailed Description

The invention will be further elucidated by means of specific embodiments in the following description, in conjunction with the drawings, in which: for those skilled in the art, modifications of the invention in various equivalent forms will fall within the scope of the appended claims without departing from the principles of the invention.

Examples

As shown in fig. 1, a tube step stretch forming structure includes: the die comprises a lower die leg 1, wherein the upper end of the lower die leg 1 is connected with a lower die holder 2, a backing plate 3 is installed at the center of the lower die holder 2, the upper end of the backing plate 3 is connected with a back plate 4, the upper end of the back plate 4 is connected with a backing plate 5, a die 6 is installed at the middle side of the upper end of the backing plate 5, pressing blocks 7 are fixed on two sides of the die 6, a tube product 8 is installed at the center of the die 6, a lower push rod 9 extending out of the back plate 4 and the backing plate 3 is installed at the lower end of the tube product 8, a nitrogen spring 10 is connected at the lower end of the lower push rod 9, the nitrogen spring 10 is installed on a fixing plate 11 at the lower end of the nitrogen spring, an upper die holder 12 is arranged at the upper side of the die 6, an upper backing plate 13 is connected at the lower end of the, and a discharging block 17 is arranged on the outer side of the male die 16.

Further, the male die 16 corresponds to the tubular product 8.

When the structure of the pipe body step stretch forming table of the utility model is used, the upper template 13 descends, the male die 16 is guided into the pipe body product 8, the male die 16 and the pipe body product 8 enter the female die 6 along with the descending of the upper template, and the product thinning and stretching action is completed;

then the upper template 13 goes upward, the nitrogen spring 10 pushes the lower push rod 9 to push the pipe body product 8 to go upward along with the male die 16, and the pipe body product touches the stripping block 17 to complete stripping.
