Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal bending auxiliary devices with adjustable angles, and in particular to an adjustable sheet metal bending auxiliary device. Background Technology

[0002] Sheet metal parts are widely used in many industries, such as automobile manufacturing, electronic equipment, and architectural decoration. In these applications, sheet metal parts often need to be bent to meet different shape and functional requirements. For example, in automobile body manufacturing, many parts such as doors and engine hoods are made from sheet metal parts through bending and other processes. The accuracy and quality of the bending directly affect the overall structural strength and appearance quality of the car body. In the field of electronic equipment, the bending quality of sheet metal parts such as chassis and shells is also related to the assembly accuracy and heat dissipation performance of the equipment.

[0003] Traditional manual bending methods rely heavily on workers' experience and skills, using simple tools such as bending pliers to bend sheet metal parts. This method is not only labor-intensive but also makes it difficult to guarantee the accuracy of the bending angle. Different workers operating the same part, or even the same worker operating it at different times, can produce significant errors, making it difficult to meet the production requirements of high-precision sheet metal parts. Using ordinary fixed-angle bending dies can ensure the consistency of the bending angle to a certain extent, but the dies have poor versatility. When it is necessary to unload the bent sheet metal parts, manual pushing and picking are required, which often poses safety hazards. Therefore, an adjustable-angle sheet metal bending auxiliary device is proposed to solve the above problems. Utility Model Content
