Manhart How to adjust the shearing angle of the punching and shearing machine according to different materials and thicknesses?

When adjusting the shearing angle of the punching and shearing machine according to different materials and thicknesses, you can follow the following steps to ensure shearing quality and efficiency:
1. **Understand material properties**:
– First, you need to understand the properties of different materials such as hardness, strength and plasticity. These properties will directly affect the choice of shearing angle.
2. **Determine the shearing angle range**:
– The shearing angle is usually between 0.5 degrees and 4 degrees, but the specific value should be adjusted according to the material and thickness. For example, harder or thicker materials may require a larger shearing angle to ensure effective shearing.
3. **Specific adjustment method**:
– **Adjust according to material thickness**:
– For thin plates, a smaller shearing angle is usually required to obtain a finer shearing effect and reduce burrs. For example, for thin plates with a thickness of less than 1mm, the shearing angle may be set at around 1 degree.
– For thick plates, a larger shearing angle helps to cut the material more easily, but it may also increase the generation of burrs. Therefore, it is necessary to balance and adjust according to the specific situation. For thick plates with a thickness greater than 10mm, the shear angle may need to be set between 3 and 4 degrees.
– **Adjust according to material hardness**:
– Harder materials require a larger shear angle to ensure effective shearing. This can be achieved by increasing the angle between the shear blades.
– Softer materials may require a smaller shear angle to avoid excessive deformation or tearing.
4. **Adjustment steps**:
– **Check and prepare the equipment**: Make sure the punching and shearing machine is in good working condition and prepare the material to be sheared.
– **Turn on the equipment and position**: Turn on the punching and shearing machine, place the material in the correct position, and fix it.
– **Adjust the shear angle**:
– If the equipment has the function of directly adjusting the shear angle, it can be adjusted directly through the control panel or manual adjustment mechanism.
– If there is no direct adjustment function, the shear angle can be changed indirectly by adjusting the height of the workbench or the position of the blade. This may require some trials and adjustments until the best shearing effect is found.
– **Test shearing effect**: After the adjustment is completed, use the material for test shearing to observe the quality and accuracy of the sheared surface. If necessary, the shear angle can be further fine-tuned to achieve the best effect.
5. **Precautions**:
– Before adjusting the shearing angle, be sure to turn off the power of the punching and shearing machine to ensure safety.
– Use appropriate tools and protective equipment to avoid injuries during the adjustment process.
– During the adjustment process, be patient and careful to ensure that each step is carried out in the correct order and manner.
Through the above steps and precautions, the shearing angle of the punching and shearing machine can be appropriately adjusted according to different materials and thicknesses to obtain the best shearing effect and quality.
