[0002] Metal processing is a core process in the manufacturing industry. The efficiency and quality of metal processing will greatly affect the development of the manufacturing industry. For subsequent processing operations, it is usually necessary to process the metal raw materials. The usual processing methods include: flame cutting, water cutting, wire cutting and traditional saw blade cutting, etc. Saw blade cutting is a common way to rough process the plate. It belongs to cold cutting. It usually uses a ring-shaped endless band saw blade as the saw tool. It is a saw machine that wraps around two saw wheels and makes a unidirectional continuous linear motion to saw metal plates.

[0003] Mechanical cutting is the most common cutting method in this field. It has obvious effects in cutting aluminum, cast iron, steel, etc., and is more suitable for pipes and bars. However, with the continuous improvement of industrial requirements, general cutting equipment can no longer meet the cutting accuracy required now. In addition, this method is more harmful to saw blades, which often leads to a shorter service life of saw blades. At the same time, it can also cause the band saw blade to break, which will affect the personal safety of surrounding operators. Summary of the invention

The feedback diaphragm is respectively located on both sides of the band saw blade.

When encountering materials with greater rigidity, the vibration generated by the band saw blade will increase, and the amplitude of the vibration will also increase and be transmitted to the feedback diaphragm. The feedback diaphragm will transmit the vibration to the elastic switch. When the elastic switch is subjected to sufficient force, a trigger signal will be transmitted, thereby adjusting the operating speed of the lifting motor, so that the lifting speed of the lifting motor is reduced, reducing the risk of the band saw blade breaking, and at the same time ensuring that the end face of the metal raw material is neat.

When encountering harder metal materials, the cutting motor rotates faster, and vice versa. The water outlet speed of the pressure pump is controlled. The higher the temperature, the faster the water outlet speed of the pressure pump, and vice versa, the slower the water outlet speed of the pressure pump, thereby saving energy consumption and extending the service life of the band saw blade.
