Ⅱ.Equipment USE of Hydraulic Three-Roll Symmetrical Plate Rolling Machine of Metallurgy Machine
The plate rolling machine is mainly used for bending metal sheet, a kind of general equipment, can complete the prebending of the end face of the plate, can be rolled round, arc and some conical workpiece Angle range, in petroleum, chemical industry, boiler, hydropower, shipbuilding, industrial equipment installation and machinery manufacturing industry has a wide range of applications.
The up and down movement of the upper roller adopts hydraulic transmission. Through the hydraulic pump and cylinder to achieve the straight line movement of the roller, is characterized by stability, automatic oil return when overload, maximize the protection of the equipment; When rolling the cone, the upper roll can be adjusted at will. Compared with the manual pressing down the rolling machine, it improves the efficiency and reduces the labor intensity. It is suitable for the large workload of the rolling project.
Ⅲ.Rolling principle of Hydraulic Three-Roll Symmetrical Plate Rolling Machine of Metallurgy Machine
The structure of this machine is three rolls symmetrical. The upper roller moves vertically up and down in the symmetrical position of the center of the two lower rollers, which is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston. The two lower rollers rotate, and the output gear of the reducer meshes with the lower roller gear to realize the walking of the plate. When the lower pressure of the upper roll exceeds the yield limit of the material, the rolled material will be deformed.
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.
