The shearing machine belongs to the category of linear shearing machines, which are mainly used for cutting the straight edges of metal sheets of various sizes. It is widely used in various industrial sectors such as steel rolling, automobiles, aircraft, ships, tractors, bridges, electrical appliances, instruments, boilers, pressure vessels, etc. There are many types of shears, which includes:
1. Flat-blade shears: good shearing quality, small distortion, but large shearing force and large energy consumption. More mechanical transmission. The upper and lower cutting edges of the shearing machine are parallel to each other, and are often used for hot shearing of blooms and slabs in rolling mills.
2. Oblique blade shearing machine: The upper and lower blades of the shearing machine are at an angle. Generally, the upper blade is inclined, and the inclination angle is generally 1°~6°. The shearing force of the inclined blade shearing machine is smaller than that of the flat blade shearing machine, so the motor power and the weight of the whole machine are greatly reduced, and the practical application is the most. This type of shearing machine includes two types: hydraulic transmission and mechanical transmission according to the movement form of the tool rest.
