Introduction to Working Principle

This machine adopts a gate-type structure for the movement of the upper blade holder. The upper blade holder is supported by multiple rollers, driven by an oil cylinder to move downwards in a straight line, and then driven by a return cylinder to lift the upper blade holder and complete the cutting action.

 Rotate the upper support eccentric shaft to push the upper tool holder and compress the middle support spring to adjust the blade clearance. Shear angle adjustment is achieved by changing the relative position of the two oil cylinder pistons.

1.Material pressing: First, the foot switch sends an electrical signal to the electrical system to control the action of the hydraulic valve. The hydraulic oil enters the material pressing cylinder under the control of the hydraulic valve and first drives the material pressing cylinder to press the sheet metal.

2. Cutting: After the hydraulic oil pressure in the system rises to a certain value, the oil cylinder drives the upper tool holder to perform the cutting action.

3. Return journey: Under the control of the electrical system, the hydraulic valve opens the unloading circuit of the hydraulic system and unloads. The pressure cylinder returns under the tension of the spring. At the same time, the high-pressure nitrogen gas in the nitrogen accumulator injects the hydraulic oil stored in the accumulator into the return cylinder. The piston of the return cylinder then lifts the upper knife holder until the top dead center, and the machine returns to the state before cutting.

4. Shear angle adjustment: The hydraulic chambers of two shear cylinders are connected in series, and the electrical system controls the discharge or filling of hydraulic oil into the series pipeline to achieve the adjustment of shear angle increase and decrease.

 Reducing the cutting angle can shorten the cutting stroke when cutting thin plates, thereby improving production efficiency and reducing deformation during thin plate cutting.

 Increasing the shear angle can ensure smooth shearing of thick plate materials.
