CN201613941U - Tailor welding part for inner plate of sidewall of automobile - Google Patents

Abstract

The utility model provides a tailor welding part for the inner plates of the sidewalls of an automobile. The tailor welding part is formed by welding four pieces of sheet metal together in a tailor welding manner; the two pieces of long sheet metal are arranged on the left and the right sides vertically; the two pieces of short sheet metal are arranged opposite and separated between the two pieces of long sheet metal in such a manner that one short sheet metal is arranged above the other one; a hollow frame is formed between the two pieces of short sheet metal; and the size of the hollow frame is guaranteed to be approximately in accordance with the position of the blanking parts of the inner plates of the sidewalls on the automobile door. By adopting the tailor-welded sheet metal, a large hole is formed in the center of the inner plates of the sidewalls during blanking, so as to ensure that sheet metal can not be wasted. Therefore, the utility model can improve the utilization ratio of material, and greatly save material.

Description

A kind of vehicle side-wall inner-plate welding part

Technical field

The utility model belongs to the auto body technology.

Background technology

In Automobile manufacturing, manufacturing to the side-wall inner-plate plate is to be welded into side-wall inner-plate welding part with four plates earlier, see Fig. 2, and then carry out blanking, finished product 1 behind the blanking as shown in Figure 1, the macropore at finished product center is the car door position of reserving on the motorcar body (car door is again by fit on vehicle bodies such as hinges).As can be seen from Figure 2, four plates forming the welding part be about each block length plate 2, the centre is each short slab material 3 relatively up and down, they are welded into a complete welding plate without any hole.And as can be seen from Figure 1, during blanking, the plate at center will be stamped, and like this, stock utilization is lower, has only about 66%, is unfavorable for the reduction of cost of product.

Summary of the invention

The purpose of this utility model is the deficiency at the prior art existence, proposes a kind of improved vehicle side-wall inner-plate welding part, to improve the degree of utilization of material.

The technical solution of the utility model is as follows:

A kind of vehicle side-wall inner-plate welding part, it is welded together by four plates, two block length plates vertically are positioned at the right and left, two blocks of short slab material one on the other, and relatively separately, about between the two block length plates, with about the welding of two block length plates, reserve an empty frame between two blocks of short slab material up and down, and will guarantee the position of this sky frame and the car door size and the position consistency of size and side-wall inner-plate blanking finished product.

Adopt above-mentioned welding plate, when blanking, the macropore that forms the side-wall inner-plate center does not just need to waste plate, and the degree of utilization that can improve material like this reaches 81%, widely saving in material.

The specific embodiment

Referring to Fig. 2, this vehicle side-wall inner-plate welding part is welded together by four plates, and two block length plates 2 vertically are positioned at the right and left, and two blocks of short slab material 3 arrange one on the other, and about between the two block length plates 2.Two blocks of short slab material 3 separate up and down relatively, reserve an empty frame 4 between them, the car door size and the position consistency of the size of this sky frame 4 and position and side-wall inner-plate blanking finished product.

Claims (1)

1. vehicle side-wall inner-plate welding part, described welding spare is welded together by four plates and constitutes, two block length plates vertically are positioned at the right and left, two blocks of short slab material one on the other, and about between the two block length plates; It is characterized in that: described two blocks of short slab material up and down separate relatively, reserve an empty frame between them, the car door size and the position consistency of the position of this sky frame and size and side-wall inner-plate blanking finished product.
