Manhart What is the principle of the punching and shearing machine for straight steel?

The principle of the punching and shearing machine for straight steel can be summarized as follows:
1. **Overview of working principle**:
– The punching and shearing machine mainly drives a pair of relatively moving dies (or shear blades) through a hydraulic or mechanical transmission system to perform shearing operations.
– When working, the straight steel (or other metal materials) is first placed on the workbench of the machine, and then pressed down to the working part through the transmission part.
2. **Detailed process**:
– **Transmission part**: responsible for guiding the punching and shearing machine to move up and down.
– **Working part**: Contains punches and dies, which are fixed on the upper and lower templates of the punching and shearing machine respectively.
– **Shearing process**: When the lower template descends, the punch and die contact and cut the straight steel through shearing force. At the same time, the design of the die also determines the shape and accuracy of the cutting.
3. **Structural composition**:
– The punching and shearing machine is mainly composed of a fuselage, a hydraulic system (or an electric system), a transmission system, a shearing die, a safety protection device, etc. Among them, the electric punching and shearing machine also controls the punching and shearing of the machine through a foot switch, and can perform 30 punching and shearing actions in one minute.
4. **Application scenarios**:
– Punching and shearing machines are widely used in metal material processing, light industrial production and construction, and can punch and shear a variety of metal materials such as angle steel, channel steel, steel plate, square steel, I-beam, etc.
Summary: Punching and shearing machines use hydraulic or mechanical transmission systems, as well as punches and dies in the working part, to accurately shear straight steel. Its high efficiency and precision make it an important tool in the manufacturing industry.
