At present, steel pipe has been one of the widely used steels in national infrastructure construction. However, in many domestic factories, the degree of automation of mechanical equipment for the production of steel pipes is still not high, and many production links rely on manual labor, which is not only high labor intensity, low efficiency, but also quite dangerous, especially in the feeding section of the production line. The continuous production of steel belt is the main function of the feeding section, and the automatic shearing equipment of steel belt is an important equipment for the automation of the feeding system, which can greatly reduce the labor intensity of workers and improve the production efficiency.

The steel belt feeding section, leading the tail of the strip because the quality is unqualified, so need to be cut again after welding, take the lead in tail of shear is semi-automatic or purely human, mostly need artificial on-site operation, poor working conditions, labor intensity is big, need the number 1 ~ 3 people, also has certain risk, efficiency is low. Therefore, there is an urgent need for a shearing equipment and shearing method that can realize automatic shearing of steel strip, so as to reduce production cost and risk factor without manual operation and provide a good working environment.

Technical implementation elements:

The utility model provides a kind of steel with automatic cutting device and cutting method, in order to improve the shearing quality of steel strip, to reduce production costs, reduce labor intensity, improve production efficiency and production quality play an important role, and implement without manual operation, to reduce the production cost and reduce the risk, to provide a good working environment.

The utility model provides a steel belt automatic shearing device, which mainly includes: main drive screw, shearing machine box body, shearing tool set, bearing seat, roller, track, hydraulic power system, control system, etc.

Shear box is composed of plate welding, shearing machine box body upper part has a positive plate for steel strip through the gap, set in shear machine box body gaps have close to switch, proximity switch connected to the control system, control system based on proximity switch detects the steel belt belt speed and the detection time determine the timing of the steel band shearing.
