Release date:2014-05-26 stem:http://www.broswright.comThe roof panel roll forming machine lifespan can be developed to a longer period by making estimation of the friction coefficient in the metal roll forming operations. The test mainly consists of compressing the roof panel roll forming machine lifespan at different ratios with flat and smooth tools. At the same time, the final height and final internal diameter of the product need to be measured to get the idea of roof panel roll forming machine lifespan. During compression, to be more specific, the internal and external diameters will change according to the roof panel roll forming machine lifespan and the friction condition on the interface. Hence, roof panel roll forming machine lifespan curves might not change a lot in the internal diameter with respect to the compression ratio that is characterized by the friction coefficient. The roof panel roll forming machine lifespan test is simulated with physical properties of the cold forging steel with yield stress of more than one hundred MPa and the geometrical dimensions of steel roll forming machine in proportion to six. It is a truth universally acknowledged that the lubricant used in the roof panel roll forming machine lifespan test is molybdenum, which is widely used in cold metal forming processes.
