Problems solved by technology

Among them, the main technical problems of the hydraulic shearing machine are: (1) oil leakage causes environmental pollution; (2) low transmission efficiency, resulting in a large waste of energy; (3) hydraulic components such as pumps and valves are expensive, Difficult to maintain; (4) Large-scale hydraulic shears require a large flow rate of the hydraulic pump and a large volume of the fuel tank, resulting in a large system volume

The main technical problems of the pneumatic shearing machine are: (1) the system pressure is low, so it can only be used in occasions with small shearing force; (2) the gas is compressible, and the synchronous circuit cannot be used like the hydraulic shearing machine. Therefore, it cannot be used in occasions where the cutting width is large

[0005] The automation control level of the above-mentioned technical scheme is low. At the same time, due to the structural setting of the shearing machine drive device, linear guide rails are set on both sides to guide the linear motion, and the increase in the width of the tool holder is limited. When trying to make a large shearing machine, The mechanical structure of the device is relatively complex, which increases the difficulty of manufacturing, increases the manufacturing cost, and cannot guarantee the shearing accuracy
