Light bus side wall outer plate skin and forming process and forming equipment thereof

Abstract

The invention discloses a light bus side wall outer plate skin and a forming process and forming equipment thereof. The side wall outer plate skin comprises a left side skin, a right side rear skin and a right side front skin; the left side skin, the right side rear skin and the right side front skin are all integrally-formed plates and are provided with a plurality of horizontally-extending waist lines, the modularization thought is innovated, the rolling and stamping mode forming technology is adopted, namely, a whole set of rolling device is developed according to the section of the side wall outer plate skin, the side wall outer plate skin of an automobile body is rolled, a whole rolling device is used for rolling the side wall outer plate skin of the automobile body, after the skin is cut according to different lengths of the automobile body, a wheel arch position, a door edge position and a rear departure angle position are formed through a developed stamping die; and the forming process of rolling and stamping effectively solves the splicing problem of the side wall skin, avoids the investment of large dies, realizes the production of vehicle types with different lengths, reduces the welding deformation, improves the working efficiency, and reduces the labor intensity.

Description

technical field [0001] The invention relates to the technical field of passenger car production, in particular to a light passenger car side wall outer panel skin and its forming process and forming equipment. Background technique [0002] With the impact of high-speed rail, private cars and shipping, and the intensified competition in the bus industry, domestic excellent bus companies are paying more and more attention to the research on segmented markets; especially with the continuous improvement of people's living standards and the integration of urban and rural areas With rapid development, the demand for light buses in the passenger car segment has grown steadily; therefore, light buses will serve as a new growth point in the passenger car field, and it is particularly important to improve the manufacturing capacity of light buses. [0003] As the appearance and structural components of the bus, the side panel skin of the bus is a very important part of the car, which ...
