Description

Technical Field

[0001] The utility model relates to the technical field of shaping dies, in particular to a shaping die for a shell part. Background Art

[0002] Shell parts are generally formed by bending cut plates during production. They need to be reshaped before formal welding to avoid large gaps between the plates that affect the welding effect. Therefore, a shaping die is needed.

[0003] When shaping shell parts, it is generally necessary to use tooling to perform multiple single-sided shaping on the four sides. This will not only increase the shaping time, but also increase the labor intensity of the staff. At the same time, when shaping multiple times, the subsequent shaping will also affect the previous shaping effect, thereby affecting the overall size of the product.

[0004] For this reason, a shell part shaping die is proposed. Utility Model Content
