1. Advantage
鈼?The use of integrated valve block hydraulic system has the advantages of simple structure, stable operation, reliable performance, and convenient maintenance and repair.
鈼?nbsp;This machine continues the shearing principle of the mechanical guillotine shearing machine. The edges of the sheared material are smooth and free of burrs, and the plate is not easy to deform.
鈼?nbsp;Because of the rectangular blade, the blade has no bevel, and the four corners are all 90 degrees, so the blade can be used on all sides, which doubles the life of the shear blade.This machine can achieve the purpose of improving work efficiency by reducing the degree of shearing angle
2. Working principle
Oil pump start: The oil pump starts, starts to supply oil, and the hydraulic oil returns to the oil tank.
Shearing: While the main hydraulic oil flows into the pressure cylinder, it flows into the upper cavity of the left cylinder, and the hydraulic oil in the lower cavity flows into the upper cavity of the right cylinder. Because the area of the lower cavity of the left oil cylinder is equal to the area of the upper cavity of the right oil cylinder, the tool holder can shear downward simultaneously. The oil in the lower cavity of the oil cylinder flows into the accumulator.
Return stroke: The oil in the pressure cylinder quickly flows back to the oil tank due to the reaction force of the spring, and the hydraulic oil in the upper cavity of the oil cylinder is pushed up by the hydraulic oil stored in the accumulator and returns to the original path and flows into the oil tank.
3. Hydraulic guillotine shears to adjust the cutting angle
The shear angle becomes smaller: the oil supply of the oil pump flows into the series cavity of the two oil cylinders through the combined action of the solenoid valve. Because the hydraulic oil in the upper cavity of the left oil cylinder cannot flow back to the oil tank, there is no action, and the right oil cylinder is directed by the hydraulic oil. Moving downwards, the right side of the tool post will descend accordingly, so that the shearing angle becomes smaller.
The shear angle becomes larger: the action of the corresponding solenoid valve causes the hydraulic oil in the lower cavity of the left cylinder and the upper cavity of the right cylinder to flow back to the tank. The accumulator pushes the right cylinder to move upwards, but the left cylinder cannot move at the moment, and the right side of the tool post follows the right The oil cylinder is raised to increase the shear angle.Shearing Machine price
