How does the gantry shearing machine work?

Gantry shearing machine is a precision cutting equipment widely used in the field of metal processing. The working principle and mode can be summarized as follows:

Structural composition

• Longmen structure: As the main support of the entire equipment, it can withstand high-power servo motors and high-speed movement, ensuring the stability and accuracy of the equipment.
• Workbench: used to place metal materials to be processed and fix them with pliers or other devices to ensure that they do not move during the processing.
• Numerical Control System: The core that controls the entire equipment, responsible for calculating fixed parameters or graphics input and generating corresponding programs.
• Control system: Execute the program instructions generated by the CNC system into the equipment, and achieve various cutting operations through components such as motors, hydraulic cylinders, etc.
• Transmission system: Generally, a hydraulic transmission system is used, which delivers hydraulic oil to the hydraulic cylinder through an electric pump, thereby driving the up and down movement of the scissor arm.
• Scissor arm and blade: The upper and lower scissor arms move up and down through the scissor holder, allowing the blade to clamp the metal sheet for cutting. The upper cutting edge is usually inclined, while the lower cutting edge is straight, and the two are cut alternately under the pressure of the hydraulic cylinder.

Working principle of gantry shearing machine

• Input parameters or graphics: The operator inputs parameters or graphics such as the size and shape of the metal material to be processed through the CNC system.
• Program generation: The numerical control system calculates based on input parameters or graphics and generates corresponding control programs.
• Execution instructions: The control system receives program instructions generated by the CNC system and drives the scissor arm to move up and down through components such as hydraulic cylinders driven by motors.
• Cutting operation: During the working process, place the metal sheet that needs to be cut on the scissor arm, lower the scissor arm through the hydraulic system, and clamp the metal sheet with the blade. Then, the hydraulic system provides sufficient pressure to allow the blade to cut the metal sheet.
• Safety protection: In order to ensure the safety of operators, gantry shearing machines are usually equipped with safety protection devices such as safety gratings and emergency stop buttons. When the operator enters a dangerous area or in case of an emergency, the safety protection device will send a signal to stop the cutting action.

Applicable materials

• Scrap metal: The gantry shearing machine can effectively process lightweight steel materials, steel bars, steel plates, nickel plates, round steel, steel pipes, scrap copper, scrap steel, scrap iron, lightweight metal structural components, etc. These scrap metals can be processed by gantry shearing machines and cut into specifications suitable for reuse, thereby achieving resource recycling.
• Plastic non-ferrous metals: including stainless steel, aluminum alloys, copper materials, etc. These materials need to maintain their original physical properties and surface quality during the processing, and the gantry shearing machine can meet these requirements with its precise shearing ability and good processing effect.
• Large dismantling site materials: such as car shells, large lightweight materials, etc. At scrap car dismantling sites and other places, gantry shearing machines can efficiently process these large metal structural components, cutting them into small pieces that are easy to handle and transport.
• Metals with specific shapes and structures, such as color steel tiles, bicycle racks, motorcycle racks, scrap car iron sheets, hydraulic oil drums, refrigerator iron sheets, TV casings, angle steel, channel steel, etc.

Characteristics and advantages

• Efficiency: The gantry shearing machine can efficiently complete the cutting and processing of various shapes of metal materials, meeting the needs of the production line.
• Accuracy: Through precise control of the CNC system, the precision and consistency of cutting can be ensured.
• High degree of automation: Some gantry shearing machines have functions such as automatic loading, feeding, and discharging, reducing manual operations and improving production efficiency.
• High safety: equipped with safety protection devices, effectively ensuring the safety of operators.

In summary, the gantry shearing machine plays an important role in the field of metal processing through its precise structure and efficient working principle. It is also widely used in the processing of furnace materials in factory casting workshops and metal cutting in the mechanical construction industry. It can not only improve processing efficiency and reduce production costs, but also reduce the generation of waste and achieve the maximization of resource utilization.
