Metal bar polishing device

Abstract

The invention discloses a metal bar polishing device which comprises a metal bar clamping device, a metal bar fixing frame, a left polishing machine and a right polishing machine. The metal bar clamping device comprises an installation frame, a pneumatic chuck and a 180-degree rotating air cylinder which drives the pneumatic chuck to rotate on the installation frame. The left polishing machine isfixed to a left lifting frame, the left lifting frame is fixed to an output shaft of a left lifting air cylinder, the left lifting air cylinder is fixed to an output shaft of a left side push air cylinder, the left side push air cylinder is fixed to an output shaft of a left linear actuator, the right polishing machine is fixed to an output shaft of a right side push air cylinder, the right side push air cylinder is fixed to an output shaft of a right linear actuator, the left polishing machine polishes the top face of a metal bar, the right polishing machine polishes the side face of the metal bar, the 180-degree rotating air cylinder enables the bottom face of the metal bar to be upward, and face turning is facilitated for polishing. The structure is simple, the polishing degree can be adjusted, and therefore the surface polishing effect of different metal bars is ensured.

Description

technical field [0001] The invention relates to the technical field of grinding and polishing equipment, in particular to a grinding device for grinding the surface of a metal bar. Background technique [0002] Before forging, heat treatment or rolling, the metal surface needs to be polished. The main purpose is to remove the oxide layer and burrs on the surface of the metal rod, and to make the roughness of the metal surface meet the specified requirements. When polishing , in addition to the need to control the supply of the grinding machine to change the grinding degree of the metal rod surface due to the process requirements, more importantly, it is necessary to further process the roughness of the metal surface to increase the flatness of the metal surface. In the reference document, the application No.: 201621257624.2, Name: An end grinder for special-shaped pipes and rods, which can only grind the two ends of metal rods, but cannot automatically grind the top and bott...
