Cold Bender
Use Skills of Cold Bender:
1. Add enough lubricating oil before use, and check whether all parts are in good condition, whether the rotation direction of the oil pump is consistent with the specified direction, and check whether there are cracks in the workpiece, pressing pad, top pad and supporting pad. Work can be started after the test operation is confirmed to be normal.
2. The operation of the steel on the bracket, and wear in the bending machine fixed frame, steel stuck in the two rolling wheels, pay attention to adjust the same level.
3. Start the pump button, control a reverse lever that oil cylinder top roller on steel, hard cylinder rod on the top roll after observation, for the first time can be bent 3 ~ 4 cm, start (left) feed forward button, make steel (left) even move forward, after putting in place to stop, measuring steel bending, meets the requirements after loosening remove the steel cylinder jacks, If not required, then control the reversing rod to make the cylinder 1000 top pressurized bending steel, top bending 1~2cm, start the backward (right) feed button, make the steel backward (right) uniform movement, stop after in place, measure the bending degree of the steel, after meeting the requirements, release the roller top of the cylinder to remove the steel, continue bending if not required, until reaching the requirements. It must be noted that the section steel is really stuck in the rolling wheel before starting the hydraulic cold bending machine.
