Description

Technical field [0001] The invention relates to an arc bending system for an automobile luggage rack, in particular to an arc bending machine for an automobile luggage rack and a method for processing the luggage rack, and belongs to the technical field of automobile parts processing equipment. Background technique [0002] With the development of the automobile industry, the demand for car luggage racks is also increasing. The backward processing equipment and processing methods in the past can no longer meet the requirements of the modern automobile industry for the production batch and product quality of automobile luggage racks. In the past, the outdated process of punching and forming was usually used. Due to the instability of aluminum materials, defects such as cracks and breaks often occurred during the stamping process. The scrap rate was high and the output was low. At the same time, some products with large bending arcs cannot be used. One-time forming needs to be div...
