What Is Hydraulic Guillotine Shearing Machine?

Hydraulic guillotine shearing machine is a kind of metal plate processing equipment that uses hydraulic drive system for shearing operation, mainly used for shearing metal plates of various thicknesses.

Compared with mechanical shearing machine, hydraulic guillotine shearing machine has the advantages of simple structure, strong shearing force, low noise and stable operation, and is suitable for mass cutting of medium and thick plates.

1. What is hydraulic guillotine shearing machine working principle?

The working principle of hydraulic guillotine shearing machine is mainly based on the hydraulic transmission system to push the knife frame up and down to complete the shearing of metal plates.

Working steps:

The whole process can be divided into the following steps.

1) Hydraulic system drive

Hydraulic pump: The motor drives the hydraulic pump to extract the hydraulic oil from the oil tank and deliver it to the hydraulic cylinder after pressurization.
Hydraulic cylinder: After the hydraulic oil enters the hydraulic cylinder, it pushes the piston to move, thereby driving the tool holder to move up and down.
Pressure control: The hydraulic system adjusts the shear force through the pressure valve to ensure that the shearing process is smooth and safe.

2) Tool holder movement and shearing process

Upper tool holder presses down in a straight line: The hydraulic cylinder pushes the upper tool holder down in a straight line in the vertical direction, and the blade fixed on the upper tool holder begins to contact the plate.
Shearing action: The upper blade is gradually pressed down, forming a shear force with the lower blade fixed on the workbench to cut the metal plate.
Shearing gap adjustment: The gap between the upper and lower blades can be adjusted by adjusting the bolt. According to the thickness of the plate, selecting an appropriate gap can ensure the shearing quality and flatness.

3) Back stop device controls the length

Back stop positioning: The position of the back stop is adjusted by the CNC system or manually to determine the length of the sheared plate.
Precision control: High-end hydraulic shearing machines are usually equipped with CNC systems. The position of the back gauge can be accurately controlled to ensure the accuracy of the shearing size.

4) Return and reset

Hydraulic return: After the shearing is completed, the hydraulic system causes the hydraulic cylinder to move in the opposite direction through the reversing valve, and the upper knife holder returns to the initial position.
Preparing for the next shearing: The back gauge device can be adjusted automatically or manually to prepare for the next shearing operation.

5) Safety and monitoring system

Overload protection: The hydraulic system is equipped with an overload protection valve to avoid equipment damage due to overload shearing.
Photoelectric protection device (optional): High-end equipment is usually equipped with a photoelectric protection device to prevent operators from misoperating in the shearing area.
Pressure and position sensor: Used to monitor the shearing force and knife holder position in real time to ensure the stability and safety of the shearing process.

Workflow summary：

Start the hydraulic pump → the hydraulic cylinder pushes the cutter head down → the upper blade cuts the plate → the hydraulic cylinder returns in the reverse direction → prepares for the next cut.
