Why should we pay attention to cylinder when buying CNC bending machine
Oil cylinder is used to load hydraulic oil, and numerical control bending machine is a kind of machine used to bend metal sheet. When we use CNC bending machine to bend materials, we must bend in the middle section. If we bend at one side, then when one cylinder touches the workpiece, the other cylinder continues to go down. Until the other cylinder touches the lower die, the two cylinders begin to pressurize. The cylinder works high at one side and low at the other, and soon CNC bending machine cylinder. It will damage and leak oil.
Secondly, try not to choose two cylinders of CNC bending machine, because such CNC bending machine working life is too short. When the workpiece is in the middle of the CNC bending machine and the cylinder is on both sides, the bending of the slider is affirmative. In addition, the reaction force produced by the inclination of the slider causes the middle of the slider to protrude outwards, which leads to inaccurate bending of the CNC bending machine.
Since two cylinders of CNC bending machine can not be selected, then three cylinders of CNC bending machine, the third cylinder in the middle, the force point is directly in place, the slider does not deform, will not protrude, fully ensure the accuracy of CNC bending machine, but also can extend the service life of equipment.
In addition to the proper selection of CNC bending machine itself, some important parts of CNC bending machine have to be adjusted reasonably, such as the press foot of CNC bending machine, which is used to press steel plate when bending. If the seal of CNC bending machine leaks, the pressure of press foot will be insufficient, and the phenomenon of steel plate skidding will occur, resulting in the damage of scissors and clippers.
In this regard, we must pay attention to check the press foot of CNC bending machine to prevent leakage of its seals. If the problem has occurred, we should replace the seals in time to ensure that the press foot of CNC bending machine has enough pressure to press the steel plate, so as to provide a good basis for the smooth completion of the bending work.
The above is why you want to buy CNC bending machine to see the specific content of the cylinder, I hope to help you.
