Description

A cutting device with safety protection function

technical field

The invention relates to the technical field of cutting equipment, in particular to a cutting equipment with a safety protection function.

Background technique

The methods of gate removal include grinding wheel cutting, sawing, hammering, shearing, flame cutting, etc. Because grinding wheel cutting has the advantages of wide application range, high efficiency, flat cutting surface and small residual roots, grinding wheel cutting is mostly used in the gate removal process. The technical level of gate cutting machines in our country is still relatively backward. Most of the gate cutting machines on the market are manual cutting machines, and the representative ones are hand-operated grinding wheel cutting machines and pedal grinding wheel cutting machines. More advanced is the semi-automatic grinding wheel cutting machine driven by hydraulic pressure, the grinding wheel can be lifted up and down, and the workbench can move back and forth, left and right.

So far, most domestic investment casting manufacturers still use manual fixed grinding wheel cutting machines. Operators wear protective clothing, masks, heat-insulating gloves and other equipment to cut workpieces. There is no dust removal device during the cutting process, and there are quite a lot of dust and impurities in the workshop. , The working environment in the workshop is very harsh and the pollution is very serious. The cutting process has great potential harm to the human body. First of all, when the casting is cut by hand on the high-speed rotating grinding wheel, the vibration of the workpiece is very severe, which will cause indirect damage to the hands; secondly, if the worker is not skilled in cutting, the grinding wheel may be damaged and the grinding wheel may be broken, and the high-speed moving grinding wheel fragments will directly damage the The human body; the final cutting process produces a large amount of smoke and dust that spreads to the entire workshop. Workers inhale free silica dust for a long time, which will cause silicosis and other related occupational diseases. A large amount of smoke and dust are generated when the grinding wheel cutting machine is working. Silica powder and ground metal powder. These powders will be harmful to the human body if they are inhaled by the human body. Therefore, the existing casting gate cutting equipment does not take protective measures against the smoke and flying debris generated during the cutting process. Therefore, we propose a cutting equipment with safety protection functions.
