Description

Efficient spinning machine

Technical Field

Background

Spinning is a metal processing technology without cutting processing, which integrates the technological characteristics of forging, extrusion, stretching, bending, ring rolling, transverse rolling, rolling extrusion and the like. The spinning forming of the spinning machine is a process of propping a metal cylinder blank, a flat blank or a prefabricated blank against a spinning machine mandrel by a tail jack, driving the mandrel and the blank to rotate by a main shaft, simultaneously extruding a material on the rotating mandrel by a spinning wheel from one side of the blank, and enabling the material to generate continuous plastic deformation point by point, thereby obtaining hollow rotator parts in various busbar shapes.

In the spinning process, especially in the thin plate spinning process, if the spinning pass or the spinning tool, the speed and the like are not well controlled, the material is easy to wrinkle, and under the condition of a certain thickness of the material, an appropriate working fillet radius value of the spinning roller, namely an R value, is adopted for preventing wrinkling. In the spinning process, a spinning ring moving along the surface of the material is formed at the contact position of the spinning wheel and the material, and the spinning ring is kept until the edge of the material, so that the material at the edge is relatively stable and is not easy to wrinkle. The wheel with small R value is easier to form the spinning ring, while the wheel with large R value is difficult to form the spinning ring, so that the material is very easy to wrinkle. If the R value is too small, the pulling force of the spinning ring on the material during spinning is too large, and the material is extremely easy to thin and crack; also, if the R value is too large, the thinning of the material is reduced, and a relatively smooth product surface is obtained, but the material is liable to wrinkle and the product is not well adhered to the mold, and the defect of diameter expansion is liable to be caused, so that a suitable spinning wheel is required to be selected according to the shape, thickness and other characteristics of the workpiece.
