Description

Technical Field

[0001] The utility model belongs to the technical field of preformed rods, in particular to a preformed rod that can be stably clamped. Background Art

[0002] For the processing and production of preform rods, such as in the wire drawing process, it is necessary to use a hoist to lift the preform rods vertically. The stability of the preform rods is required to be high during the wire drawing process. However, since the preform rods are long and have a large weight, and the preform rods are a cylindrical structure with a smooth surface, only the top of the preform rod can be lifted. This is not conducive to controlling the stability of the preform rods, which will affect the subsequent wire drawing.

[0003] At the same time, during the preform feeding process of the wire drawing equipment, the preform needs to be adjusted multiple times to ensure that the preform is in a completely vertical and centered state. However, the positioning effect of existing tooling fixtures is poor, or other tools are required to assist, which is not conducive to operation.

[0004] Therefore, designing a preform that is easy to position and conveniently and stably clamped is a problem that needs to be solved by those skilled in the art. Utility Model Content
