Shear forming, also referred as shear spinning, is similar to metal spinning. In shear spinning the area of the final piece is approximately equal to that of the flat sheet metal blank. The wall thickness is maintained by controlling the gap between the roller and the mandrel. In shear forming a reduction of the wall thickness occurs.

A material ejection mechanism for a semi-shear forming mold and a semi-shear forming mold
This utility model provides a material ejection mechanism for a semi-shear forming mold and a semi-shear forming mold, belonging to the field of mold technology. The material ejection mechanism includes an inner ejector block, which is movably disposed within the forming cavity, and the direction of movement of the inner ejector block is along the opening and closing direction of the mold. A force transmission rod is provided on the inner ejector block, one end of which penetrates through the top of the forming cavity; an elastic element is also provided between the bottom of the inner ejector block and the forming cavity. This mechanism can assist in the ejection of the semi-shear forming mold, thereby reducing product defects in semi-shear forming processing and improving the product qualification rate.
