The Working Principle And Precautions Of The Shearing Machine

The main function of a shearing machine

The main function is in the metal processing industry, which is a machine that uses one blade to perform reciprocating linear motion relative to another blade to shear sheet metal. It uses a moving upper blade and a fixed lower blade, adopts reasonable blade gaps, and applies shear force to various thicknesses of metal sheet metal, causing the sheet metal to fracture and separate according to the required size.

The Shearing Machine

Working principle of shearing machine

RAYMAX shearing machine can ensure the straightness and parallelism requirements of the shearing surface of the sheet metal after cutting, and minimize the distortion of the sheet metal as much as possible to obtain high-quality workpieces. The upper blade of the cutting board is fixed on the tool holder, and the lower blade is fixed on the workbench. Rolling steel ball is installed on the workbench to prevent scratches when the sheet metal slides on it. The backgauge is used for fixing the sheet metal, and its position is adjusted by a motor. The pressing cylinder is used to press the sheet metal tightly to prevent it from moving during shearing. Safety fences are safety devices to prevent work-related accidents. The return journey usually relies on nitrogen gas, which has a fast speed and low impact.

Precautions for using a shearing machine

1. Start the shearing machine and idle for several cycles to ensure that under normal conditions, different thicknesses of plates can be cut from thin to thick.

2. When trying to cut plates of different thicknesses, it is necessary to adjust the gap between different blades. If the corresponding blade gap is not adjusted, it will affect the durability of the blade.

3. During the shearing process, turn on the pressure gauge switch and observe the pressure value of the oil circuit. When shearing a 12mm plate, the pressure should be less than 20MPa.

4. If there is a sound during operation, the vehicle should be stopped for inspection.

5. When operating the shearing machine, the temperature of the oil tank should be raised to less than 60 degrees Celsius. If it exceeds 60 degrees Celsius, the machine should be shut down and rested.
