Description

Novel wet sand blasting equipment

Technical Field

The utility model belongs to the technical field of surface treatment, it is comparatively concrete, involve a novel wet sand blasting equipment.

Background

At present, in the technical field of the existing PVD vacuum coating, after the surface of a drill bit or a cutter is subjected to film treatment, the hardness and the wear resistance of the surface of the drill bit or the cutter can be improved, so that the service life of the drill bit or the cutter can be greatly prolonged, and the PVD vacuum coating technology is widely applied to the improvement of the surface performance of the drill bit or the cutter. Some products can be directly delivered from a factory after being treated by a vacuum coating technology, but some products, especially cutters, cannot be directly delivered from a factory after being treated by the vacuum coating technology, because the surface finish and roughness of the products can not meet the requirements of an end user, in order to improve the finish and roughness of the surface of the vacuum coated products, the products after being subjected to vacuum coating need to be polished, the currently used polishing treatment mode is a dry sand blasting technology, namely, dried sand is directly sprayed on the products on a workpiece after being treated by compressed air, so that the dried sand generates friction with the metal coating on the surface of the products under the action of high-pressure gas, and the metal coating on the surface of the products is polished. By adopting the dry sand blasting polishing mode, the roughness and the smoothness of the surface of the polished product are limited, and the roughness and the smoothness of the surface of some cutter products can not meet the requirements of end-use customers. At this time, if the roughness of the surface of the tool product needs to be reduced continuously to increase the smoothness of the surface of the tool product, only the sand with finer grain size and smoother surface can be used, but the sand is usually used in a large amount, and it is not practical to select the grain size of the sand finely. In addition, when the surface of a vacuum coating product is treated by adopting a dry sand blasting mode, sand moves at a high speed under the action of compressed air, and the particle size of the sand is small, so that the sand easily leaks from gaps of dry sand blasting equipment, flying sand is arranged on the periphery of the whole dry sand blasting equipment, the flying dry sand flies in the air, and workers can possibly influence respiratory tracts after working for a long time on site, and finally suffer from dust and lung.
