The difference between Hydraulic swing beam shearing machine and hydraulic guillotine shearing machine

1. The hydraulic guillotine shearing machine has higher shearing accuracy than the hydraulic swing beam shearing machine:

(1) . Take 16*3200 hydraulic swing beam shears and hydraulic guillotine shears as an example, swing beam shearing blade and guillotine shearing blade design clearance values are less than 6 wire, but swing beam shearing machine swing arm and swing frame bearing connection between the clearance can not be eliminated, clearance and edge clearance accumulation of shear accuracy errors are generally more than 10 wire, The back guide rail of the brake plate shears body is supported by 4 large bearings, and the front guide rail is pressed by 2 bearings with compression springs behind, so that there is no clearance between the front and rear guides, and the accuracy error of the addition of clearance and edge clearance is kept below 4 wires, so that the shear material is smoother and burr free.

(2). The tool rest body of the swing beam shearing machine itself is arc, it is based on the point contact of the arc to ensure the straightness of the shear material, and guillotine shearing machine’s tool rest to make vertical linear movement relative to the blade to ensure that the shear plate deformation is small, Higher straightness.

(3). Swing beam shearing machine for rest of strength and the edge is not in the same line and the distance is far, rest after a long work prone to deformation, fatigue and make knife phenomenon is relatively serious, cause shear material part incision with burrs, and brake type shearing machine for cylinder, head, the blade in the same line and make the perpendicular to the blade motion is not easy to deformation.

2. Shear Angle is adjustable

(1). The shear Angle of tilting plate shears is fixed, and the shear speed cannot be adjusted.

(2). The guillotine shearing machine realizes Angle adjustment by adjusting the oil quantity of two engineering oil cylinders connected up and down in the closed cavity quickly: the shear Angle is extended, the shear ability is increased, the shear Angle is reduced, the shear speed is accelerated, the energy and working time are saved, and the bending degree of the plate is effectively reduced.

3.QC11Y hydraulic guillotine shearing machine rectangular edge advantage

(1). Because swing beam shearing machine blade holder blade point work arc movement, so can only be used on both sides of the diamond blade; The guillotine shearing machine blade holder because do perpendicular to the lower edge of the linear movement, direct use of four edge rectangular blade, make the service life of the blade increased 1 times.

(2). It is easy to cause twisted plate when cutting with diamond blade, and the more narrow the material is, the more serious it is. Rectangular blade can avoid this defect

(3). Cylinder life: the built-in cylinder semicircle block used by swing beam shears is difficult to lubricate and not easy to repair, and the upper and lower cavities of the sluice plate shears are filled with oil without additional lubrication, thus greatly improving the service life.

4.QC11Y hydraulic guillotine shearing machine structure performance:

(1). The second generation of hydraulic guillotine shearing machine is the ideal replacement of hydraulic pendulum shearing machine;

(2). The frame adopts closed integral steel plate welding structure, which can eliminate stress by vibration (good accuracy retention);

(3). Advanced integrated hydraulic system (less faults, easy maintenance), high pressure tubing (easy maintenance, easy replacement), simple layout, good reliability, beautiful appearance;

(4). Adopt three-point support rolling guide to eliminate support gap and improve shear accuracy;

(5). The blade gap is quickly adjusted by electric, and the LCD display is accurate and convenient.

(6). Shear Angle hydraulic electric control stepless adjustment: the shear Angle increases the shear capacity increases (can be appropriate overload shear), the shear Angle decreases the shear speed up (shearing plate can reach 8~20 times per minute).(7).Electric Backgauge, LCD digital display, point fine tuning, digital display.

5.Hydraulic swing beam shearing machine illustration:

(1), the shear Angle of the hydraulic pendulum shearing machine is fixed and cannot be adjusted. The efficiency of cutting thin plate and thick plate is the same, which means that a lot of power resources and working time are wasted when cutting thin plate. For example: a QC12Y-35X2500 hydraulic plate shearing machine motor power is 55KW, shear 35mm thick sheet 4 times/minute, because the shear Angle can not be adjusted the same shear 10mm thick sheet or 4 times/minute.

(2) in order to reduce the deformation of the frame and reduce the power of the machine, the shear Angle of the pendulum shear machine usually takes the maximum value, but the larger shear Angle of the sheet will make the workpiece under the shear produce great bending deformation
