Abstract

The invention relates to the magnetic rheo-gas cell flexible polishing tool. The said polishing tool comprises a gas cell with a polishing cloth in its front as the work face; an interlayer is in front of the said gas cell, which is filled with the magnetic rheological liquor; the said gas cell is equipped in the retainer; the said retainer is on the drive shaft with one or several pairs of electrical magnets at its front end; the said drive shaft socket joints a sleeving; the said sleeving and the drive shaft gas-tight joint; the said sleeving has outside gas entrance port and the overflow valve; the drive shaft in the sleeving opens the airflow channel that connects the said air cell. The flexibility of the polishing tool head can be controlled online, the contacting area of polishing is big, and the curve face polishing has high efficiency, well adaptation to the curvature change, which can be profiling remembered.

Description

(1) Technical field [0001] The invention relates to a mold curved surface polishing tool used in conjunction with a machine tool with a power head, especially for automatic polishing of mold curved surfaces, and is suitable for the occasion of realizing automatic polishing technology. (2) Background technology [0002] 65% of the surface of the mold cavity is a curved surface, of which 40% is a free-form surface. The service objects of the mold industry include automobile cover parts, motorcycle cover plastic parts, household appliances such as TV sets, washing machines, and air conditioners, and telecommunications products such as mobile phone cases and car lamp cases. Molds in these industries, especially plastic molds, have high requirements on the surface roughness of the cavity, and some of them need to meet the mirror surface requirements. Therefore, curved surface polishing has become an indispensable process link. According to statistics, polishing accounts for 10% o...
