One, hydraulic plate shearing machine blade turn
Adjust the upper tool rest to zero degree by using the shear Angle smaller button, then remove the table guide plate to loosen the screw fixing the lower blade, take out the lower blade in order, then loosen the screw fixing the upper blade, take out the upper blade in order, and then turn over each blade, successively install the blade, and then install the blade. Check whether the interface between the blades is smooth and flat. Finally, fix all the blade screws and install the guide plate
On the can.
Two, how to replace the hydraulic plate shears pipe seals?
First, put the tool rest of the hydraulic plate shearer to the bottom dead point, then cut off the power supply of the machine tool, loosen the pipe of the oil infiltration part and take out the bad seal, and then paint a layer of butter in the joint groove, and then install the new seal into the groove, tighten the pipe, and finally reset the hydraulic plate shearer with oil, and enter the normal use.
Three, hydraulic shears do not produce working pressure?
- Check whether the positive and negative rotation of plate shearing motor and oil pump is correct.
- Clean the spool of the safety relief valve of plate shearer.
- Two four-way solenoid valve of the hydraulic system of the plate shearer is cleaned.
Four, hydraulic shears tool rest return speed is slow
- Fill the plate shears with oil again.
- Check whether there are signs of oil seepage and oil leakage at the connecting parts of the plate shears.
- Check the nitrogen pressure in the accumulator of plate shears (normal nitrogen pressure is 4-5mpa,
