Advanced Mechanical Punching Machines

Mechanical punching machines not returning to their original position is a common problem, which can be caused by various factors. Here are some possible reasons and corresponding solutions summarized:

1. Overload protection device triggered
Mechanical punching machines are usually equipped with overload protection devices. If the load they are subjected to during operation exceeds the design limit, the overload protection device will automatically activate, causing the punch to be unable to return to its original position. In this case, it is necessary to check whether the working load of the mechanical punch exceeds the specified range and take measures to reduce the load or adjust the operating mode.
2. Mold issues
Unreasonable or damaged mold design may also cause the punch to fail to return to its original position. Check the condition of the mold, and if any problems are found, it may be necessary to replace the mold with a new one or repair the existing mold.
3. Power and control system issues
The problem of the punching machine not returning to its original position may be caused by unstable power supply or control system failure. Firstly, ensure that the power supply is functioning properly and check if there are any malfunction indicator lights on the control panel. If problems are found, professional electrical maintenance personnel may be required to inspect and repair them.
4. Wear or damage to mechanical components
If the mechanical components of a mechanical punch press, such as cams, sliders, etc., are worn or damaged, it may also cause the mechanical punch press to not return to its original position. For example, a faulty cam may cause the skateboard to not move. In this case, it is necessary to check whether the cam is worn, damaged, or contaminated, and replace or adjust it accordingly.
5. Hydraulic system malfunction
For hydraulic transmission mechanical punching machines, hydraulic system failures such as high oil temperature, insufficient oil pressure, or malfunctioning relief valves may also cause it to fail to return to its original position. Check the hydraulic oil volume, pipelines, and valves for blockages or leaks, and promptly clean or replace damaged components.
6. Improper mechanical assembly
Improper mechanical assembly may also result in the mechanical punch not returning to its original position. For example, machining accuracy errors in synchronous wheels or gear racks may result in inaccurate pulse equivalent settings in motion control cards, leading to misalignment. In addition, a mechanical structure with high resistance at a certain point may also cause the punch to fail to return to its original position. Check the assembly of the mechanical structure and adjust or reassemble it if necessary.
7. Interference issues

In some cases, electromagnetic interference within the equipment, mutual interference between equipment in the workshop, or improper grounding during equipment installation may also result in the mechanical punch not returning to its original position. Check the grounding status of the equipment, use an oscilloscope to monitor the pulse frequency to determine the time of interference occurrence, and remove or move the pulse signal away from the interference source.

Through the above inspection and maintenance steps, the problem of mechanical punch not returning to its original position can be effectively diagnosed and solved. If self handling is ineffective, it is recommended to contact professional maintenance personnel for inspection and repair.
