Description

Technical Field

[0001] The invention relates to the technical field of spin forming, and in particular to a spin forming machine which is easy to position. Background Art

[0002] The spinning machine is a metal plastic forming device. Its equipment and molds are relatively simple. It manufactures various rotating workpieces through plastic deformation.

[0003] For example, Chinese patent CN113857322B discloses a CNC spinning machine, which makes a metal circular plate blank rotate together with a mold core by pressing, and controls the roller feed and applies pressure to make the blank close to the mold core and gradually deform until the spinning is completed.

[0004] However, in order to ensure the uniformity of the finished product, the center of the metal circular plate blank needs to coincide with the center of the mold core, but it is difficult for the spinning machine to automatically center the metal circular plate blank; at the same time, for some inward-converging rotating workpieces, their mold cores are mostly composed of multiple identical petal-shaped modules. After molding, the mold core and the molded workpiece need to be taken out, and then the petal-shaped modules need to be taken out one by one, which makes the overall demolding more inconvenient.
