Efficient grinding device for metal bar

Abstract

The invention discloses an efficient grinding device for a metal bar. The grinding device comprises a hollow shell. A cavity is formed inside the shell. Multiple extending-and-contracting rods are arranged in the shell. Friction sheets are arranged on ends, facing the cavity, of the extending-and-contracting rods. A to-be-ground bar penetrates through the middle of the cavity so that the outer edge of the to-be-ground bar can be touched by the friction sheets. A driving mechanism is arranged at an end of the to-be-ground bar. The to-be-ground bar can be driven to do translational movement along the length direction of the to-be-ground bar or rotate around the axial direction of the to-be-ground bar by the driving mechanism. The extending-and-contracting rod in the highest position is a hollow rod, and a water diversion pipe is arranged inside the hollow rod. A water spraying pipe is connected to the bottom of the water diversion pipe, and the water spraying pipe extends to the exteriorof the hollow rod. A water storage tank is arranged at the bottom of the shell. Water drainage holes are formed in the wall between the shell and the water storage tank. The water storage tank is connected with the water diversion pipe through a main conduit. A water pump is arranged on the main conduit. By means of the efficient grinding device for the metal bar, the grinding effect of the surface of the metal bar can be improved.

Description

technical field [0001] The invention relates to a grinding device, in particular to a high-efficiency metal rod grinding device. Background technique [0002] After the metal parts are made into blanks, they generally need to be processed later, such as turning, grinding, milling, punching, etc. Among them, after the rough machining of the metal bar, the blank needs to be ground externally. The existing grinding generally uses a single-directional friction plate to grind the blank. This grinding method not only has low grinding efficiency, but also often leads to insufficient grinding Uniformity will affect the grinding effect; in addition, a large amount of dust will be generated during the grinding process, and the existence of dust will adversely affect the quality of the surface of the blank. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency metal bar grinding device, which can improve the grinding effect of the sur...
