Working principle of bending machine

The bending machine mainly generates pressure through the hydraulic system and transmits it through the mold to ultimately obtain the desired material shape. Its usage is as follows:

Firstly, connect the power supply, turn on the key switch on the control panel, and then press the oil pump start button. At this point, you can hear the sound of the oil pump turning.

Travel adjustment is crucial. When using a bending machine, attention must be paid to adjusting the travel, and a test drive must be conducted before bending. When the upper mold of the bending machine descends to the bottom, there must be a gap of plate thickness, otherwise it will cause damage to the mold and machine. There are two ways to adjust the itinerary: electric quick adjustment and manual fine adjustment.

The selection of bending slots generally requires choosing slots with a width 8 times the thickness of the board. For example, when bending a 4mm sheet metal, a slot of about 32 should be selected.

Rear material adjustment usually includes electric quick adjustment and manual fine adjustment, similar to the method of a shearing machine.

Press the foot switch to start bending. Unlike the shearing machine, the bending machine can be released at any time. Release the foot switch to stop the bending machine, and then press it again to continue the downward movement.

The operating principle of the bending machine is:

Connect the power supply, turn on the switch device on the control panel, and then turn on the oil pump. At this point, the oil pump rotates and the machine has not yet started operating.

Before carrying out bending work, it is necessary to test whether there is a gap distance of approximately one board thickness between the upper mold and the bottom. Proper testing can ensure that the mold machine is not damaged.

Choose a slot width that is approximately 8 times the thickness of the sheet, for example, when bending a sheet with a thickness of 5 millimeters, the slot width should be around 40 millimeters.

Press the foot switch to start running the machine, relying on the force of the foot to operate. When the foot is released, the machine will stop, and press it again to continue running.
