[0057] Example 2:

[0058] Control method of hydraulic system for automatic adjustment and compensation device of guide rail of zigzag multi-blade shearing machine:

[0059] An even number of double-output shaft double-acting hydraulic cylinders 1 are installed on the adjusting seat 8. On the same side, they not only have a tensioning effect but also a lifting effect. The coordinated control of the first bidirectional hydraulic control check valve group 5-1, the second bidirectional hydraulic control check valve group 5-2, the first reversing control valve group 6-1, and the second reversing control valve group 6-2 enables the adjusting seat double-output shaft double-acting hydraulic cylinder 1 to achieve a working state of pure tensioning or pure lifting, or a balanced state in which tensioning and lifting act simultaneously.

[0060] Example 3:

[0061] Under the action of the double-output shaft double-acting hydraulic cylinder 1, the adjusting seat 8 moves to fit the fixed seat 10 and forms a gap with the movable guide rail 9 below.

The coordinated control of the fifth bidirectional hydraulic control check valve group 5-5, the sixth bidirectional hydraulic control check valve group 5-6, the fifth reversing control valve group 6-5, and the sixth reversing control valve group 6-6 can realize the working state of pure tensioning or pure lifting of the fixed-base double-output shaft double-acting hydraulic cylinder 7 on the movable guide rail 9 in the vertical direction, or the balanced state of tensioning and lifting acting simultaneously.

[0064] Example 5:

[0065] After the position of the adjusting seat 8 changes, a gap is formed between the mating surface of the adjusting seat 8 and the movable guide rail 9. Under the action of the fixed seat double-output shaft double-acting hydraulic cylinder 7, the contact gap between the movable guide rail 9 and the guide rail surface of the scissor slide is adjusted, so as to achieve the purpose of adjusting the guide rail gap of the zigzag high-efficiency multi-blade shearing machine.

[0066] Example 6:

[0067] Pressure sensors monitor the pressure status of each control cylinder. Through program control, when the pressure drops below the monitored value, each accumulator and control valve group will activate to replenish the pressure in a timely manner, ensuring that each control cylinder is in a relatively balanced state.
