Manhart How to ensure the shearing quality of the punching and shearing machine?

To ensure the shearing quality of the punching and shearing machine, a series of steps and precautions need to be followed. Here are some key points, presented in a clear structure:
I. Material preparation
1. **Material selection**: Select the appropriate material according to the shearing requirements to ensure that the material’s strength, toughness and ductility meet the requirements.
2. **Material cleaning**: Clean the surface of the steel plate mesh to ensure that the shearing line is clear and free of impurities or oil.
3. **Material placement**: The steel plate mesh needs to be leveled and aligned with the shearing line to avoid offset or deformation during the shearing process.
II. Tool selection and adjustment
1. **Tool selection**: Select a shearing blade section shape that matches the profile section to ensure shearing quality.
2. **Tool adjustment**:
– Adjustment of the upper and lower blade spacing: completed through the knob on the top of the machine, determined according to the thickness and type of the material.
– Blade slope adjustment: Adjust the slope pitch between the upper and lower blades to ensure a straight cut.
3. Parameter setting
1. **Shearing speed**: Set the appropriate shearing speed according to the type and thickness of the material to avoid problems caused by too fast or too slow.
2. **Shearing length**: When trying to cut, the shearing length should not exceed 15mm to facilitate subsequent adjustments.
4. Operation process
1. **Operator**: Must be proficient in the safe operation specifications of the punching and shearing machine, and ensure that one person is responsible for command when two or more people operate.
2. **Operation process**:
– Make sure the power is turned off and the equipment is stable before cutting.
– After turning on the power, start the machine according to the operating procedures and pay attention to the shearing process.
– After the shearing is completed, turn off the power in time and clean the equipment.
5. Maintenance and care
1. **Tool maintenance**: Regularly check, grind and replace the tool to ensure the sharpness and integrity of the tool.
2. **Equipment cleaning**: Keep the mold and workpiece clean to avoid the influence of impurities or oil on the shearing quality.
6. Quality inspection
1. **Shearing surface quality**: Check whether the cut after shearing is flat, burr-free, and tear-free.
2. **Dimensional accuracy**: Use a standard template or ruler to measure the size after shearing to ensure that it meets the preset value.
By implementing the above steps and precautions, the shearing quality of the punching and shearing machine can be ensured. In actual operation, it is necessary to comprehensively consider multiple aspects such as materials, tools, parameter settings, operation processes, and quality inspections to achieve the best shearing effect.
