Abstract

The invention discloses a machining process method of a rubber workpiece step surface. The method includes the following steps of firstly, machining an annular end face shear mark on the outer end face of a circular platy rubber blank workpiece through a hollow drill bit, wherein the depth of the end face shear mark is equal to the height of a small-diameter section of the workpiece to be machined, and the diameter of the end face shear mark is equal to the diameter of the small-diameter section of the workpiece to be machined; secondly, machining an annular circumferential shear mark on the outer circumferential face of the blank workpiece through a tool which rotates relative to the blank piece, wherein the mark bottom of the circumferential shear mark and the mark bottom of the end face shear mark coincide; thirdly, removing an annular body, disengaged from the blank workpiece, between the end face shear mark and the circumferential shear mark. In the whole process, the whole unnecessary part of the blank workpiece can be smoothly cut off, and therefore the rubber workpiece step surface is rapidly machined, and the method has the advantages of being low in cost and short in cycle and is quite suitable for machining and producing small batches of workpieces.

Description

technical field

[0001] The invention relates to a processing method for the step surface of a rubber workpiece. Background technique

[0002] For some workpieces of rubber materials, such as figure 1 The rubber gasket shown includes an annular gasket body 11, and the outer peripheral surface of the gasket body 11 has a stepped surface. Since the rubber is soft and easy to deform, the forming of the stepped surface must take into account the influence of errors caused by these factors. Therefore , the traditional processing and forming method mainly adopts vulcanization processing, and abrasive tools need to be made during vulcanization processing, the production cost is high, the cycle is long, and it is not suitable for single-piece and small-batch production. Contents of the invention

[0003] The purpose of the present invention is to provide a processing method for the step surface of rubber workpieces, which is used to solve the problems of high cost and long cycle c...
