How to handle the malfunction of the joint punching and shearing machine of Manhart (Guangdong) CNC Machine Tool Co., Ltd?

When a joint punching and shearing machine malfunctions, the handling steps should be determined based on the specific type of malfunction. The following are some common types of faults and their handling methods:
1. * * Difficulty in threading * *:
-Check if the frame material has excessive deformation during molding. If so, adjust the molding machine to correct the molding problem.
-Confirm whether the gap between the moving knife and the fixed knife is aligned. You can use a flashlight to observe and make corresponding adjustments.
-Check if there is any deviation in the threading angle, and if necessary, adjust the angle position of the feeding platform.
2. * * Cut continuously * *:
-Check the working pressure of the hydraulic cylinder. If the pressure is insufficient, it should be adjusted to the normal range (usually 10-15 megapascals).
-Check if the blade does not fit tightly or if there is a phenomenon of slipping. If so, tighten the adjusting screws and fixing screws.
-Check if there are any foreign objects between the two blades. If there are, remove the moving blades, clean them, and reinstall them.
-If the cutting edge is damaged or not treated with electric spark, it should be disassembled for inspection and a repair plan should be developed.
-When the travel of the moving knife is insufficient, the travel time should be adjusted.
3. * * Clutch slipping or brake loosening * *:
-Clean the surface of the machine and keep it clean. Check if the gear cover and nut are tightened, or if the conical friction cone needs to be replaced.
-Adjust the braking torque, tighten the brake band, and ensure that the brake wheels are securely fixed.
-Check and adjust the clearance control of the hydraulic cylinder to be between 0.03-0.05mm.
-Maintain appropriate lubrication and add oil according to the manufacturer’s instructions.
-Adjust the oil pressure to ensure it is within the normal operating range.
-Regularly clean the filter and keep it clean.
When dealing with malfunctions in the combined punching and shearing machine, it is essential to follow the manufacturer’s provided operation and maintenance manuals and ensure the safety of operators. If the malfunction is complex or cannot be resolved on its own, it is recommended to contact professional maintenance technicians for maintenance and repair. In addition, regular preventive maintenance and upkeep of the machine can effectively reduce the occurrence of faults, improve the stability and service life of the machine.
