A hard alloy tool passivation device and working method

Abstract

The invention relates to a hard alloy tool passivation device and a working method, comprising a casing, the casing is connected with a plurality of protective door driving parts, and the protective door driving parts are all connected to the protective door, which can drive the vertical movement of the protective door, and the casing The inner space is divided into multiple areas. There is also a rotatable turntable inside the shell. The turntable is equipped with multiple tool holders that can rotate around its own axis. The turntable can drive the tool holders to switch between different areas. There is a spray gun, and the spray gun is connected with the abrasive material return mechanism and the air source. The passivation device of the present invention has good safety, avoids waste of abrasive material and water resources, and has good processing quality.

Description

technical field [0001] The invention relates to the technical field of surface finishing equipment, in particular to a hard alloy tool passivation device and a working method. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] At present, the equipment used for cemented carbide sandblasting edge treatment is sandblasting machine. Due to the impact and cutting action of abrasives on the surface of the workpiece, the sandblasting machine can obtain a certain degree of cleanliness and different roughness on the surface of the workpiece. The mechanical properties are improved, and sandblasting can be divided into dry sandblasting and wet sandblasting. Wet sandblasting uses the abrasive pump as the power supply for the abrasive fluid, and uses the compressed air as the acceleration power for sandblasting. , to achieve the purpose of strengthening, cleaning, spraying...

AI Technical Summary

Problems solved by technology

[0004] The inventor found that the current wet sandblasting machine has the following defects: there is no safety protection device in the sandblasting area, and the abrasive liquid will splash outside the equipment, which will pollute the environment, cause waste of abrasives and water resources, and cause harm to the staff. There are certain safety hazards. The freedom of movement of the sandblasting nozzle is limited, which will cause uneven sandblasting area, small sandblasting coverage area, and inconsistent surface treatment effects of workpieces.
