When a high-speed punch press is in a state of high-speed operation and high torque for a long time during the punching operation, the crankshaft of the high-speed punch press is inevitably worn. Continuous high-speed punching equipment has a very high operating frequency. The small radial clearance between the crankshaft head and the bearing is crucial to the engine performance. If the clearance changes abnormally, it may cause the crankshaft head to wear more or even break, which in turn causes a series of problems such as increased engine vibration, increased noise, and increased fuel consumption. This common faults of high-speed punch presses must be dealt with in time, otherwise small problems may turn into major faults. Let's briefly analyze what Repair solutions for high-speed punch press crankshaft wear are.
Repair solutions for high-speed punch press crankshaft wear need to be determined according to specific circumstances. Generally speaking, the more serious the damage to the crankshaft, the more difficult and expensive it is to repair.
1. Case 1: There are slight wear and scratches on the crankshaft surface
Repair solution: Repair the crankshaft by grinding or polishing.
2. Case 2: The crankshaft is seriously worn
Repair solution: Carbon-based polymer composite materials can be used for repair
3. Case 3: There are cracks and deformations in the crankshaft
Repair solution: Welding repair, high-temperature welding repair, this method will make the steel body brittle and there are risks. Traditional welding repair is prone to hidden dangers, which may aggravate the thermal stress of the journal, change the material structure, and greatly reduce the original toughness and high strength of the crankshaft;
Apply nanopolymer material technology to repair the crankshaft, which is a new type of high-performance carbon fiber polymer with high bonding strength, good comprehensive mechanical properties, corrosion resistance, and easy molding. Repair the crankshaft. This method is almost harmless to the material and structure of the shaft, and is a relatively reliable method.
If the crankshaft is too seriously damaged, it may be necessary to replace it with a new crankshaft, because such problems are generally difficult to solve with simple repair methods. Moreover, poor repair methods may aggravate the problem, affect the strength and stability of the crankshaft, and may affect the safety of the engine;
The above are some Repair solutions for high-speed punch press crankshaft wear. A lot of new knowledge and a lot of Experience in repairing high-speed punch presses are discovered and accumulated in the daily use of punch presses and in punch press production operations. There are often many reasons for the occurrence of failures. Sometimes when we troubleshoot, we do not find the real cause of the failure, which leads to subsequent failures. After the punch press has a problem, we must find out the cause and repair it, and pay attention to more communication and record maintenance experience.
