Description

Technical Field

[0001] The utility model relates to the technical field of automobile sheet metal bending, and more particularly to an automobile sheet metal bending device. Background Art

[0002] In the current automotive manufacturing industry, sheet metal bending devices face a common technical challenge. Due to the diverse shapes, sizes, and materials of automotive sheet metal parts, bending operations often require the selection of pressure plates of different specifications and shapes based on the characteristics of the workpiece. This diverse demand requires operators to perform a tedious disassembly and assembly process when replacing pressure plates, which not only consumes a lot of time but may also affect bending accuracy due to improper installation of the pressure plates. At the same time, the interchangeability between different pressure plates is poor, and storage and management are relatively difficult, which seriously affects production efficiency.

[0003] In addition, the existing sheet metal bending device also faces many inconveniences when adjusting the position of the pressure plate. The operator needs to frequently adjust the horizontal position, vertical height and pressure of the pressure plate according to the bending requirements of different sheet metal parts. However, the existing fixing and adjustment mechanisms are often complex in structure, cumbersome to operate, and the adjustment accuracy is difficult to guarantee. This not only increases the labor intensity of the workers, but also easily leads to problems such as inadequate adjustment or unreliable fixation, thereby affecting the bending quality and reducing the practicality and production efficiency of the equipment.
