Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Referring to Fig. 1 and Fig. 2, a surface finishing method based on flow field constrained hydrodynamic abrasive flow mainly includes the following steps:

[0023] a. On the structured surface 2 of the processed workpiece 4, the constrained module 5 is arranged through the fixture, and the constrained module 5 and the structured surface 2 of the processed workpiece 4 constitute the flow channel 3 of the liquid-solid two-phase abrasive flow;

[0024] b. Connect the flow channel 3 with the abrasive particle flow circulation system;

[0025] c. Start the abrasive particle flow circulation system. Under the constraint of the shape of the flow channel 3, a flow field-constrained hydraulic abrasive flow of high-speed circulating flow is formed in the flow channel 3 to impact the structured surface 2 of the workpiece 4. Erosion micromachining.

[0026] In the above a...

Abstract

The invention relates to based on flow field bound type liquid operated abrasive particle flow finishing method. It includes the following steps: allocating bound module by clamp on work piece structuring surface to form liquid solid two phase abrasive particle flow passage; connecting the passage with the abrasive particle flow circulating system; starting up abrasive particle flow circulating system; forming flow field bound type liquid operated abrasive particle flow in passage to process erosion micro cutting for the work piece structuring surface. The invention can effectively process the structuring surface finishing with small size and special structure.

Description

(1) Technical field [0001] The invention relates to a structured surface finish processing method of mechanical parts, in particular to a method capable of realizing structured surface finish processing of mechanical parts by using a flow field-constrained hydraulic abrasive grain flow without using a polishing tool. (2) Background technology [0002] The surface composed of grooves, grooves, holes, prisms, pyramids, narrow slits and other special-shaped surfaces and flat or curved surfaces is called a structured surface. For example, precision injection molds, in order to ensure the quality of injection molding, not only have extremely high requirements on the surface roughness of the mold surface involving the surface of the injection molded parts, but also have high requirements on the surface roughness of the injection runner. [0003] A large number of structured surfaces exist in the field of mold manufacturing. In mold processing, in order to eliminate the traces left...
