Embodiment

[0022] A method for producing spare tire compartment parts of an automobile needs to go through four processes of drawing, shaping and punching, trimming and punching, and flanging and shaping.

[0023] The molds required for the drawing process such as figure 1 As shown, it consists of a drawing lower die, a blank holder and a drawing upper die. The drawing lower die is composed of a binder plate 1, a lower template 2, and a drawing punch core 3. The drawing upper die is composed of a die core 4 Composed of the upper die base 5, there are 6-8 drawing guide plates between the drawing die and the blank holder for guidance and connection, and there are 6-8 drawing guide plates between the drawing die and the drawing lower die and 4 drawn guide pillars are used as guides and connections.

[0024] The molds required for the shaping and punching process are as follows: figure 2 As shown, it is composed of a shaping lower mold and a shaping upper mold. The shaping lower mold is c...

Abstract

The invention relates to a method for producing an automobile spare tire cabin part. The method for producing the automobile spare tire cabin part comprises four process steps of drawing, sizing piercing, trimming piercing and flanging sizing, the principle of motion of the four process steps is same, the principle of motion is that when a press presses down with rated pressure, an upper pad and a lower pad press a sheet stock tightly, a punch-matrix is used for drawing a flat sheet to a bottom state, the press is lifted, the lower pad ejects the part, and the part is taken out. When the part is produced, a sheet or a semi-finished part in a previous step is put on a male die of a die set in the current process step, and pressing is performed with set pressure, so a semi-finished product is obtained; and then, after stamping in the flanging sizing process step, a qualified finished product part is obtained. Compared with the prior art, the die disclosed by the invention has the advantages that the cost is reduced, the efficiency is improved, the stability is high and the like.

Description

technical field [0001] The invention relates to a method for producing parts, in particular to a method for producing parts of an automobile spare tire compartment. Background technique [0002] The spare tire compartment is an integral part of the car, and its production can only be completed through multiple processing procedures. At present, many spare tire compartment parts production methods use five processes to make parts, which reduces the stamping efficiency and makes the company The cost has increased substantially. Contents of the invention [0003] The object of the present invention is to provide a method for producing spare tire compartment parts in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A method for producing spare tire compartment parts of an automobile needs to go through four processes of drawing, shaping and punchin...
