specific Embodiment approach
[0020] Such as figure 1 It is a specific embodiment of the present invention, which specifically includes the following steps: S1, forming the pump core 1 by blanking the sheet material, and the end of the pump core 1 is extruded to form an annular notch 11;
[0021] S2. Insert the pump core 1 into the tooling fixture of the machine tool, and the annular notch 11 is located on the outside of the tooling fixture;
[0022] S3. Take two rolling knives 2 and align them with the inner walls on both sides of the same annular notch 11, and feed the two rolling knives 2 to the inside of the annular notch 11 synchronously, and the fixture drives the pump core 1 Rotating, the two rolling cutters 2 simultaneously roll and grind the inner walls of the inner sides of the annular notch 11 .
[0023] In the present invention, during the rotation process of the pump core 1 driven by the fixture, two rolling cutters 2 are used to roll and polish the two inner sidewalls of the annular notch 11...
