What aspects the high speed of shearing machine is reflected in?

The high-speed Swing Beam Shear is developed and produced on the basis of the original ordinary hydraulic gate shearing machine, and the shearing speed is nearly 2 times higher than that of the ordinary shearing machine. This fast shearing machine is suitable for the thin plate shearing process with a thickness of 6 to 16mm, and the maximum shearing length can reach 4000mm. Compared with ordinary hydraulic gate shears, at a shear angle of 3°, the speed can reach 10 times per minute when cutting a plate with a total length of 4000mm, and the speed can reach more than 40 times per minute when cutting in sections. What is the high speed of the high-speed shearing machine: In addition to the metal shearing speed is much faster than the ordinary shearing machine, the shearing machine has the following advantages:

First, the cutting quality is greatly improved, and the cutting burrs are less;

Second, the shear stress is small, effectively reducing the deformation of the sheared sheet;

Third, in the process of high-speed shearing, the time of extrusion wear of the blade is reduced, the durability of the blade is relatively increased, and the service life of the blade is improved;

Fourth, during the high-speed shearing process, the instantaneous deformation of the fuselage is small, and the shearing accuracy is effectively improved, which can reach ±0.05mm per meter. the

Due to the fast working speed of the shearing machine, high wear resistance and wear resistance requirements are put forward on the hydraulic cylinder. The numerical control shearing machine is particularly careful in the design of the hydraulic cylinder, and specially adopts No. 45 steel quenching and tempering treatment, and the inner hole is finely bored and extruded. The strength of the inner surface of the cylinder is improved; the piston rod is also quenched and tempered with No. 45 steel, and the surface is plated with nickel and phosphorus to improve wear resistance.

Due to the fast shearing speed of the hydraulic high-speed shearing machine, the temperature of the oil circuit of the hydraulic system also rises rapidly. Generally, the control range of the hydraulic oil temperature of the shearing machine is 45 to 55 degrees Celsius. If the oil temperature is too high, the thinning of the hydraulic oil will directly affect the cutting. This is one of the reasons why many domestic shearing machine manufacturers cannot produce high-speed shearing machines.
