Cutting machine used for hardware machining and having good heat dissipation effect

Abstract

The invention relates to a cutting machine used for hardware machining and having a good heat dissipation effect. The cutting machine comprises a bottom box, a cutting piece, a rotating pipe, two bearings and two connecting boxes, wherein the shape of the connecting boxes and the shape of the bottom box are both rectangular, the cutting piece is installed on the rotating pipe, and the rotating pipe is located between the two connecting boxes; a mounting hole is formed in the side, close to the cutting pipe, of each connecting box, the rotating pipe penetrates through the mounting holes, and the rotating pipe and the mounting holes are in sliding and sealing connection; and the bearings are in one-to-one correspondence to the connecting boxes, the bearings are located between the connectingboxes and the cutting piece, an auxiliary mechanism is arranged in the bottom box, and heat dissipation mechanisms are arranged in the two connecting boxes. The cutting machine used for hardware machining and having a good heat dissipation effect achieves the function of eliminating sparks during cutting, avoids scald accidents and improves the safety. Moreover, the heat dissipation effect of thecutting piece and the rotating pipe is also promoted through the heat dissipation mechanisms.

Description

technical field [0001] The invention relates to the field of cutting machines, in particular to a cutting machine with good heat dissipation effect for metal processing. Background technique [0002] Grinding wheel cutting machine, also called grinding wheel saw, is suitable for construction, hardware, petrochemical, mechanical metallurgy and hydroelectric installation and other departments. It is a common equipment for cutting materials such as carbon element steel and element pipe. [0003] During the use of the existing grinding wheel cutting machine, the grinding wheel will generate a lot of heat, and after the heat is transferred to the main shaft, it will cause the bearing and the main shaft to bite, damage the shaft or bearing, and reduce the service life. Not only that, during the cutting process, A large number of sparks will be generated, which is prone to burn accidents and reduces safety. Contents of the invention [0004] The technical problem to be solved b...
