The bending machine is a kind of equipment used to make bending pipe fittings, and the die mandrel is one of the main components of the bending machine. Their setting and debugging are crucial to ensure the production efficiency and quality of the bending machine. The following I will introduce in detail the steps and precautions for setting and debugging the die mandrel of the elbow machine.
1. Mold mandrel setting
1. Measure the length and bending Angle of pipe fittings
Before setting the mold mandrel, it is necessary to measure the length of the pipe fitting and the Angle that needs to be bent. This step is very important because it affects the setting of the die mandrel and the bending quality of the pipe fitting.
2. Select the right mold mandrel
According to the length and bending Angle of pipe fittings, choose the appropriate mold mandrel. The diameter and Angle of the die mandrel should match the diameter and Angle of the pipe fitting, otherwise the bending quality will be affected.
3. Install the mold mandrel
Install the die mandrel on the bending head of the bending machine, ensuring that the die mandrel is positioned correctly and does not move or swing.
4. Adjust the position of mold mandrel
Adjust the position of the die mandrel according to the pipe length and bending Angle. The position of the die mandrel should be accurate to the millimeter to ensure the bending quality of the pipe fitting.
5. Fix mold mandrel
After adjusting the position of the mold mandrel, use screws to fix it. Make sure the die mandrel does not move or loosen, otherwise it will affect the bending quality.
Second, mold mandrel debugging
1. Adjust the bending Angle
After installing and fixing the die mandrel, debugging is required to ensure that the bending Angle of the pipe fitting meets the requirements. When adjusting the bending Angle, it can be controlled by adjusting the Angle and speed of the elbow machine. It should be noted that the Angle should be adjusted gradually to avoid excessive bending or breaking of the pipe.
2. Check the bending quality of pipe fittings
After adjusting the bending Angle, check the bending quality of the pipe fittings. The following points should be noted when checking:
- Whether the bending radius of the pipe fittings meets the requirements;
- Whether the bending Angle of the pipe fittings meets the requirements;
- Whether the bending of pipe fittings has indentation, deformation and other problems.
If it is found that the bending quality of the pipe fittings does not meet the requirements, it is necessary to readjust the mold mandrel position and bending Angle.
3. Adjust the length of mold mandrel
If the bending quality of the pipe fittings meets the requirements, but the length does not meet the requirements, the length of the die mandrel needs to be adjusted. When adjusting the length of the die mandrel, it can be controlled by increasing or decreasing the length of the mandrel.
4. Check the grinding condition of the mold core. When using the elbow, the mold core rod will gradually wear out. If the die mandrel is badly worn, a new die mandrel needs to be replaced. When checking the wear of the mold mandrel, the following points need to be noted:
- Observe whether there are scratches and cracks on the surface of the mold mandrel;
- Measure whether the diameter of the mold mandrel meets the requirements;
- Check whether the bending Angle of the mold mandrel is deformed.
It should be noted that when replacing the mold mandrel, a new mold mandrel that matches the diameter and bending Angle of the pipe should be selected.
In SUMMARY:
Setting and debugging of die mandrel of elbow machine is an important step to ensure production efficiency and quality. In the process of setting and debugging, it is necessary to pay attention to the matching of pipe length, bending Angle, mold mandrel diameter and bending Angle, as well as the accurate adjustment of mold mandrel position. In addition, it is also necessary to check the bending quality of the pipe fittings and the wear of the die mandrel, and adjust and replace it in time.
