Discussion On The Function And Operation Instructions Of The Mandrel Of The Pipe Bender

During the bending process, the mandrel mainly plays the role of supporting the inner wall of the bending radius of the conduit and preventing its deformation. At present, domestic pipes are bent on machine tools. If mandrel is not used, its quality is difficult to guarantee. There are many forms of mandrel, such as cylindrical mandrel, universal single, double, three and four ball head mandrel, directional single and multi ball head mandrel, etc.

When the mandrel of the small pipe bender is far away from the tangent point and in the backward position, it will not be able to fully stretch the data on the outside of the bend, so the position of the mandrel will cause a great rebound, which may reduce the complete angle or increase the radius. If the radius becomes larger, it can advance to the tangent point. Adjust the setting of the mandrel. If the pipe is constantly broken, it is clarified that the data is too hard, and the too hard data cannot be fully stretched. The pipe with complete annealing can be used to deal with the problem.

The so-called Springback Control refers to the possibility of changing back to the original shape after the elbow is processed and formed. The springback will reduce or increase the bending degree according to the bending radius of the elbow. Generally, if the bending degree is smaller, the springback will be smaller. The influence of springback pressure die position and pressure has different radius.

The pipe of small pipe bender will be twisted or folded. The reason for this may be that the data is too hard, so the inner diameter cannot be shrunk during bending. This phenomenon can be handled by inserting a mandrel.

When operating the pipe bender, be sure to ensure that the equipment is in the correct grounding state, do not connect the voltage exceeding the specified voltage range, and do not stop plugging when it is charged. Generally, experienced equipment maintenance engineers will do a good job in this detail, involving maintenance specifications and safe operation methods.

The following points should be avoided when using the pipe bender correctly:

1. Plug and unplug after the equipment is stopped. Do not touch the wires and cables blindly to avoid pulling off.

2. Not enough hard objects to stop hitting the switch and encoder.

3. You can't hit the display with a sharp object.

4. Place the electrical box in a ventilated center to avoid stopping operation in an environment with corrosive gas.

5. The equipment shall be kept clean, especially there shall be no sundries in the sliding groove of the sliding block and clamping block.

6. The equipment shall be cleaned and inspected regularly, and the pipe bender shall be maintained in time. The power supply shall be cut off before operation.

These are some of the reasons that affect the service life of the pipe bender. Try to avoid these problems in the daily use of the pipe bender. Reducing the wear of the pipe bender can prolong the service life of the machine!
