锻压设备经常处于强烈的冲击振动条件下工作,设备上的大型铸锻件往往会产生意外的损坏。但这些大型零件的加工周期长,需用重型加工设备,加之毛坯定货难等困难。因此为了保证正常生产,就不得不用大量的资金储备各种大件的备件。实际上这些备件有的很长时间(有的达20年之久)用不上,资金大量积压。为解决这一问题,目前最适用的办法就是采用维修的办法。下面介绍我厂的一些实例。 1.2500吨热模锻压力机曲轴裂纹的修理
Forging equipment often in a strong shock and vibration conditions, equipment, large castings and forgings often have unexpected damage. However, these large parts of the long processing cycle, the need to use heavy processing equipment, combined with the rough ordering difficult and so difficult. Therefore, in order to ensure normal production, we have to use a lot of money to reserve a variety of large spare parts. In fact, some of these spare parts have been used for a long time (some up to 20 years old), with a large backlog of funds. To solve this problem, the most suitable method at present is to adopt the method of maintenance. Here are some examples of my plant. Repair of 1.2500 Tons Hot Die Forging Press Crankshaft Crack
