Problems solved by technology

[0005] (1) Segmented skin, large molds are required for the manufacture of each section, the cost is high, and it is not universal, especially when the model is replaced, even if it is a small change, a new mold must be redeveloped to manufacture The cost is high and the cycle is long
[0006] (2) Segmented skins must be spliced ​​and welded sequentially at the body welding site to form. The process is relatively complicated. In severe cases, the entire side skin is scrapped, resulting in heavy losses

Embodiment 1

[0026] Embodiment 1. A process and mold structure of an automobile integrated skin are provided.

[0027] Its automotive one-piece skin processing method includes three steps: roll forming, cutting forming, and hydroforming:

[0028] Roll Forming:

[0029] Such as figure 1 As shown, the roll forming step is a step of forming for the cross-sectional shape of the side skin. Due to the different types, models, and sizes of automobiles, the cross-sectional shape of the shell is also different. Therefore, it is necessary to set the cross-sectional shape in advance for each roll forming. According to the cross-sectional shape, set the plate roller Relevant parameters of the press (relevant parameters here refer to the relevant parameters of the cross-sectional shape of the car skin. Because the types of cars are different, the skin cross-sectional shapes are also different, so before each operation, according to the car’s The general category sets the corresponding shape of the s...

Abstract

The invention provides an automobile integrated covering method and an automobile integrated covering die structure. The automobile integrated covering method sequentially includes the following steps of rolling forming, cutting forming and pressing forming.

Description

technical field [0001] The invention relates to a process method of an automobile skin, in particular to a process method of an automobile integrated skin and a mold structure thereof. Background technique [0002] The skin on both sides of the car is an indispensable and important part of the exterior of the car. For the sake of beauty and firmness, designers often design it into a curved surface shape with ribs while satisfying the basic functional shape, which makes the overall outline change. For such sheet metal parts, in the traditional sheet metal manufacturing industry, hydraulic forming is often carried out by means of one-time forming of special molds through hydraulic equipment. [0003] However, the current conventional hydraulic equipment can only suppress boards with a length of less than 2 meters. For large vehicles such as buses and minibuses, the length of the skin on both sides is often 6-8 meters, so it must be divided into 3-4 meters. Each segment is hyd...
