Release date:2014-05-26  stem:http://www.broswright.com

The 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.

At the same time, due to the axial and radial symmetries, the roof panel roll forming machine lifespan simulation has to be made with one quarter of the ring and two types of elements should be used to model the contact element. This is mainly because the cross section of the initial roof panel roll forming machine lifespan model and the number of solution time steps can be applied at the flat tool’s points. The results of the roof panel roll forming machine lifespan and friction simulation are supposed to change in a parallel configuration, which can be obtained by the computational steel roll forming machine model in an accurate manner. The roof panel roll forming machine lifespan test simulation results are in agreement with previous results in the case of maximum friction, which indicates that barreling effect of roof panel roll forming machine lifespan is not correctly modeled for high friction values. Calibrations curves can be obtained by numerical method have a better prediction for steel roll forming machine and are less sensitive for higher friction coefficients in the process of the cold forging. The prescribed displacement of roof panel roll forming machine lifespan can be applied to the punch in order to consider the hardening friction between punches mainly based on the lubrication conditions and tools’ finishing surface. The equivalent stress field within the roof panel roll forming machine lifespan can be obtained and compared to the macro etching section even in the darker regions and the most stressed regions.
