Reasons for different pressures on both sides of the bending machine
First of all, if it is an external reason, for example, there is a heavy object near the bending machine, which affects the uneven force on the sliders on both sides of the working cylinder. At this time, we only need to remove the heavy object and re-install the two working cylinder sliders of the bending machine. A return to normal movement will solve the problem. It should be noted that some users often do not pay attention to the cleaning and maintenance of the bending machine when using the bending machine, which is wrong. Before using the bending machine, we need to ensure that there is no foreign matter in the body of the bending machine, and always pay attention to the working condition of the bending machine, which can effectively reduce the uneven pressure on both sides of the bending machine.
The second reason for the uneven pressure on both sides of the bending machine is the most common situation, which is caused by the machine itself. The main reason is that the two working cylinders are pressurized at both ends of the slider, which causes the working center of gravity of the bending machine to be biased to the middle, and the working center of gravity of the bending machine is biased to the middle, which will cause uneven stress on both sides of the bent product. Uneven force will naturally affect the molding of the product and subsequent work.
Solution of different pressure on both sides of bending machine
For this reason, it is generally necessary to use "deflection compensation and pressure compensation" to solve it. The specific operation is to place a deformation amount opposite to the direction of force deformation on the worktable between the slider and the upper die of the bending machine to realize the variable compensation of the slider and the worktable, and to promote the working cylinder sliders on both sides of the bending machine. The pressure distribution is more uniform. In addition, deflection compensation can also be realized by hydraulic compensation and mechanical compensation. These methods are very common solutions, and there will be corresponding prompts in the manufacturer's manual for the specific operation of the bending machine.
