Tips: （This part of the passage is not the main body.）
Sheet metal shearing machine is an equipment that uses one blade to make reciprocating linear motion relative to the other blade to cut plates.
Through moving upper blade and fixed lower blade, it exerts a shear force on metal or steel plates of various thicknesses with reasonable blade clearance. Then, the plates can be shaped or separated according to the required size.
The structure of the shear machine mainly includes:
Transmission system, frame, slide block, tool holder, pressing mechanism, retaining mechanism, balancer, electrical control system, lubrication system, and other auxiliary devices (sealing ring, valve, N2 nitrogen return, etc.).
There are 3 kinds of transmission forms of sheet shearing machines: mechanical transmission, hydraulic transmission, and hydraulic mechanical combined transmission.
The appearance structure and performance function of metal sheet shearing machines are closely related to the transmission mode used.
So metal steel shearing machine is divided into 2 main types according to the transmission system: mechanical shear and hydraulic shear.
Mechanical Shearing Machine VS Hydraulic Shearing Machine
According to the working principle, we can divide shearing machines into the following two categories: Mechanical shear and Hydraulic shear.
- Mechanical shearing machine: up moving type and down driving type.
- Hydraulic shearing machine: swing beam shears and guillotine shears.
The shear thickness is less than 10 mm, it is always a mechanical shear machine. If the thickness is more than 10 mm, it is generally a hydraulic plate shearing machine.
Generally speaking, the old small shearing machines for sale in the past mainly used mechanical transmission. But with the development of technology and production, the hydraulic plate shearing machines have occupied the mainstream market. Now, most of the new shearing machines for sale use a hydraulic system.
