Electric forging press is a machine that changes the shape of metal, mainly for metal and mechanical cold working. Forging presses include plate rolling machines, shearing machines, punches, presses, hydraulic presses, hydraulic presses, bending machines, etc.
How to maintain the electric forging press?
1. External overall inspection.
Thoroughly clean the outside of the forging press, check whether all the fastening screws are loose, whether all parts are safe, and whether there is welding, cracking or deformation. There should be safety warning signs on the fuselage.
2. Trial run check.
After the forging press rotates, check for air leakage, and at the same time, check for abnormal vibration of the machine, and perform full lubrication as required. Carefully observe for collisions, friction and stagnation. Is there any abnormal sound? Use power machinery to drive low-speed operation and observe the operation status of each part.
Inspection and adjustment of forging parts
3. Carry out the pressure test of the whole machine.
The pressure used in the test is 1.25 times the working pressure. Check that the piston extends to the maximum working stroke. Hold the pressure for 15 minutes. The value of the pressure gauge reading should not exceed 4% of the test pressure. No leakage; after all pressure is removed, the pointer of the pressure gauge returns to the “0” position, the parts should not be damaged, there should be no significant deformation of the pull rod, and no moving parts are stuck. etc.
