Technical Field

The utility model relates to a welding tool, in particular to a hot plate welding tool.

Background

In a sheet metal stamping progressive die, in order to ensure smooth feeding of a material belt, the material belt is usually required to be floated to a certain height. When the continuous die is used for production, the cylinder sheet metal part is usually used for cutting off a fixed knife edge, but the blanking clearance of the fixed knife edge is smaller, and the cylinder part is difficult to accurately and rapidly pass through the fixed knife edge, so that the stability of the cylinder part when the continuous die is used for production is poor, and the production efficiency is lower. In actual production, a single-step die is often used for producing the cylindrical part, but the production efficiency is low, and the die manufacturing cost is high.

For the existing automobile left back door hinge mounting plate mold, there is a need for an automobile mold capable of solving the above problems to improve the stamping quality of the workpiece. The labor force of workers is consumed, the fastening force is low, and the quality is affected due to inaccurate positioning or deformation of objects; and in the disassembly process, the process is complicated, the workload is large, and the forming quality and the manufacturing progress of the parts are affected.
