Manufacturing technique of automobile skylight frame

Abstract

The invention discloses a manufacturing technique of an automobile skylight frame. The manufacturing technique comprises the following steps: 1, manufacturing two single components at the opposite side of the automobile skylight frame through a progressive die A; 2, manufacturing another two single components at the opposite side of the automobile skylight frame through a progressive die B; 3 fixing the four single components which are manufactured in step 1 and step 2 onto a workbench of full-automatic welding equipment, and then the four single components are spliced to an integral automobile skylight frame; and 4, welding adjacent two single components of the four single components through the full-automatic welding equipment respectively so as to manufacture the integral type automobile skylight frame. The manufacturing technique uses the progressive dies to process split manufacturing and full-automatic welding equipment to weld, on the basis of guaranteeing overall strength of the skylight frame, the utilization rate of raw materials is greatly improved, the manufacturing is high-efficient, and machines and manpower are saved.

Description

technical field [0001] The invention relates to the manufacturing field of auto parts, in particular to a manufacturing process of an automobile sunroof frame. Background technique [0002] At present, the top of many cars, especially cars, is equipped with a sunroof, and the sunroof frames used to connect and install the sunroof glass are mostly integral quadrilateral metal frames. For the manufacture of automobile sunroof frames, after comprehensively considering the cost of stamping dies, the specifications of stamping machine tools and other manufacturing cost factors, the conventional manufacturing process usually uses a whole piece of metal sheet as a raw material, and performs successive manufacturing processes. Each manufacturing process The manufacture of part of the sunroof frame structure is completed through small and medium-sized stamping dies, so as to finally complete the manufacture of the entire automobile sunroof frame. [0003] Adopting the manufacturing ...

AI Technical Summary

Problems solved by technology

[0003] Adopting the manufacturing process of the above-mentioned automobile sunroof frame will inevitably lead to an extremely low effective utilization rate of metal sheets as raw materials, often less than 20%, and the larger the frame, the lower the utilization rate of raw materials; using the above-mentioned manufacturing process of the automobile sunroof frame generally needs to be divided into Four or five manufacturing processes complete part of the manufacturing respectively, and finally complete the overall manufacturing together. The number of operators and stamping machine tools required is large, and the transmission of parts needs to be completed between successive manufacturing processes. The positioning of the workpiece needs to be completed in the process, which is time-consuming and labor-intensive, and the manufacturing efficiency is not high
