Ⅳ.Operating rules of Hydraulic Three-Roll Symmetrical Plate Rolling Machine of Metallurgy Machine

Operation and use of the winding machine staff should understand the structure of the machine, and have some electrical common sense, switch on the main power supply (leakage circuit breaker is required) no-load operation (winter oil pump motor idling 10-20min before normal work). And check whether the components on the equipment operate normally. Check whether the anchor bolt is firm, check whether the screw bolt is loose, if the rolled plate is gas cutting material, should first remove the gas cutting metal slag, solder joints and accessories, to ensure the normal service life of the roll.

(1) Check before operation

1. Check each lubrication point interface.

2. Start the hydraulic motor, check whether the pressure is normal, pay attention to whether the rotation direction of the motor is correct, whether the voltage is normal, operate the manual valve handle, lift the upper roll (pay attention to the upper position of the lead screw fulcrum), make the upper roll and the lower roll parallel, the error is not greater than 0.3-2mm..

(2) Operation process

1. Send the plate between the upper and lower rollers.

2. Adjust the plate so that the edge of the plate is parallel to the lower roller. According to the accuracy requirements, the error should not exceed 1-2mm.

3. Roll the template, operate the manual valve handle, press down with the upper roll, and observe the pressure in the process of rolling.

4. Start the main motor, start winding, working on both sides of the winding machine shall not be anyone, in order to prevent the winding workpiece out of the accident, so that the motor anyway turn, after several times of pressure anyway turn, complete the winding.

5. Material removal: turn off the main motor, start the hydraulic circuit, make the upper roll rise to the removal position, press the manual valve handle, pull down the live support, fine tune the press bar downward, take out the winding workpiece, and then restore to the original position.
