How to adjust the blade gap and backgauge parameters of the CNC shearing machine for sheet metal

Reading Time: 3 minutes

After buying the metal plate CNC shearing machine for a long time, you need to adjust the blade gap of the shearing machine. If you don’t know, you can adjust it according to the introduction of the editor. Let’s take a look.

  1. Remove the blade and clean it piece by piece.
  2. The blade can be used on all four sides, and the one that has been selected can be installed tightly. And check the straightness of the blade in the horizontal and vertical directions.
  3. Remove the upper blade and clean it piece by piece. In the same way, the blade can be used on all sides, and the selected one side is tightly installed. And check the straightness of the blade in the horizontal and vertical directions.
  4. The upper blade is fixed and cannot be adjusted. We adjust the blade gap of the shearing machine by adjusting the lower blade.
  5. Find the left and right screws of the lower blade to increase the clearance, generally on the outermost side.
  6. ​​Find the two set screws on the left and right of the lower blade to push the lower blade to narrow the gap. There is a locking backup nut on it. Generally on the inside.
  7. Loosen the left and right four bolts on the lower blade table.
  8. The upper blade will be lowered to the proper position by manual turning, and the operator will start adjustment at the blanking area of ​​the shearing machine.
  9. Use a feeler gauge to roughly adjust to 0.5 mm from the unoccupied part of the left hand and upper blade.
  10. Manually turn the blade to the middle position and adjust it to 0.5 mm.
  11. Manually turn the blade upward to move the blade up to the right position where the upper and lower blades are not disengaged. The middle position is roughly adjusted to 0.5 mm.
  12. Manually turn the upper blade to the proper position and start fine adjustment.
  13. Use the feeler gauge to fine-tune from the part where the blades of the left hand and the upper and lower blades are not occluded until the feeler gauge can enter three wires and five wires can not enter.
  14. Manually turn the blade up to the middle position and start fine-tuning until the feeler gauge can enter three wires and five wires cannot enter.
  15. Manually turn the blade up to the position where the upper and lower blades are not disengaged on the right side and start fine-tuning until the feeler gauge can enter three wires and five wires can not enter.
  16. The above is fine-tuned for the new car to the point that the feeler gauge can enter three wires and five wires can not enter.

The method of adjusting the parameters of the sheet metal CNC shearing machine machine tool:
Metal plate CNC shearing machine machine tools are mainly used for shearing thickness of steel plate materials. Commonly used shearing machines are divided into three types: flat shear, rolling shear and vibration shear. Shears with a cutting thickness of less than 10mm are mostly mechanically driven, and those with a thickness greater than 10mm are hydraulically driven. The following is the specific method of adjusting the parameters.

1.The size of the metal plate CNC shearing machine machine tool is mainly related to the back gauge. If you want to have an accurate size, you should adjust the back gauge of the shearing machine, so as to avoid problems and protect the equipment. Normal operation and use, to have a good use effect.


2.The adjustment of the baffle of the metal plate CNC shearing machine machine tool is realized through the CNC panel. Therefore, its automatic adjustment mainly depends on whether the CNC panel is set properly and whether the operation is in place. The general operation is to click on the data input, enter the back gauge data, and then press the automatic and then press the start, so that the back gauge can be automatically in place.

3.If the steel plate is cut by the metal plate CNC shearing machine, the cutting thickness is related to the gap of the steel plate. If the steel plate gap is 1 to 3 mm, the adjustment amount is 1 to 2 mm, and if it is 4 to 10 mm, the adjustment amount is 3 to 5 mm. According to the specified shearing thickness, adjust the shear gap of the shearing machine. It is not allowed to cut two different specifications and different materials at the same time. The cut sheet requires a flat surface, and it is not allowed to cut narrow sheets that cannot be compacted. Correct adjustment and use of equipment are required.
