A processing method of a two-side top press wedge

Abstract

The application provides a processing method of two-face top press wedge, and belongs to the field of presses. The method is as follows: a cylindrical blank is cut into sub-blanks of equal size, and then the sub-blanks are processed into wedges, and the wedges can form a wedge assembly after being spliced together; the diameter size of the cylindrical blank is increased by twice the processing allowance in the radial direction based on the diameter size of the wedge assembly; the processing allowance in the radial direction includes a cutting allowance Δ2, wherein L is the slit width when the cylindrical blank is cut into sub-blanks, and θ is half of the central angle corresponding to each sub-blank. The application fully considers the processing allowance that needs to be left during the processing of the cylindrical blank, especially the processing allowance that needs to be left due to the influence of the slit after the cylindrical blank is cut into sub-blanks, greatly improves the calculation accuracy of the processing allowance, reduces material waste and improves processing efficiency.
