Description

Technical Field

[0001] The invention relates to the technical field of auxiliary tooling for wheel production, and in particular to an auxiliary tooling for welding a rim strip. Background Art

[0002] The initial raw materials of the rim are all strip-shaped thin plates. When making the rim, it is usually necessary to first roll the strip into a round shape and then perform positioning welding at the joint. Existing strip welding is usually performed by manual clamping. The manual clamping method is prone to the following problems: 1. Axial misalignment (such as Figure 1 1. The end face is misaligned (as shown in the figure), resulting in uneven and scrapped wheel rims in the subsequent molding process; 2. The end face is misaligned (as shown in the figure Figure 2 As shown), the subsequent process will crack and be scrapped; 3. The placement position is misplaced (as shown Figure 3 As shown in the figure, the amount of upsetting is uneven, resulting in crack expansion and scrap.
