What are the main aspects of the shear accuracy of the hydraulic shears?

The shear precision of hydraulic shears is extremely high, which is mainly reflected in the following aspects:

CNC Shearing Machine

(1) The rear guide rail of the knife holder body of the hydraulic guillotine shearing machine is supported by 4 large bearings, and the front guide rail is pressed by 2 bearings with compression springs on the back, so that there is no play between the front and rear guide rails. The accuracy error of the gap addition is kept below 4 wires, so the sheared material is smoother and free of burrs.

(2) The hydraulic guillotine shearing machine tool holder moves vertically and linearly relative to the lower blade to ensure that the shearing plate has small distortion and more accurate straightness.

(3) Hydraulic guillotine shears are not prone to deformation because the cylinder, tool rest, and blade are in the same straight line and move perpendicular to the lower blade.

4. The windings and iron core of the linear motor are directly exposed to the air, so the heat can be discharged into the air in time, and the temperature will not rise too high even if it runs for a long time.

The disassembly steps of the CNC shearing machine blade:

1. Start the hydraulic shearing machine, adjust the cutting angle to 1, 0°, and adjust the blade gap to the maximum value of 0, 48mm;

2, Anhui Yongya waits for the hydraulic shearing machine tool post to run up and down for several rounds, shut down the machine tool, and disconnect the main power supply of the hydraulic shearing machine;

3. Remove the protective fence of the hydraulic shears, the pressure cylinder (note that there is hydraulic oil overflow) and the knife seat cover;

4. Remove the lower blade of the hydraulic shearing machine first: loosen all the installation screws of the lower blade, and use a long wooden square to press the lower blade firmly on the back side of the machine tool to prevent the lower blade from falling backwards or slipping off. Remove the screws on the lower blade. , And then pull out the lower blade from the side of the hydraulic shear;

5. Disassemble the upper blade of the hydraulic shearing machine: loosen all the mounting screws of the upper blade, insert two suitable wooden squares between the workbench and the upper blade, and firmly press the upper blade, and remove the screws on the upper blade. Then slowly loosen the pad into the wood square, and at the same time pull out the upper blade from the side of the hydraulic shearing machine.
