GuangYuan · GuangZhiYuan Technology Sensing Heating Equipment Process Due to the continuous increase in cutting pressure during forming, the thickness of the metal is increased, while the area is constantly shrinking, and the final outer metal is severely wrinkled, and the folded metal is in pressure The frictional resistance between the front circles and the fins increases, and the tissue metal flows into the concave mode, and finally the pull-up force is increased, and the strip-bound pressure stress makes it disabled. The induction heating equipment uses the following methods for the above problems, according to the plastic forming theory, the metal "less fierce, more wrinkles".
1. The material stack caused by external wrinkles, the rupture of the internal metal flow caused by the internal metal flow, and the feed resistance is adjusted by adding a puller in the outside, so that the internal material flows smoothly.
2, the grid in the corner portion is severely deformed, and the inside adjacent grids are almost unchanged, thereby determining the rupture herein is due to local expansion, need to be eliminated by adding process incisions. Through the appropriate pressure size, the rupture caused by excessive pressure can be eliminated to effectively eliminate the rupture caused by the inside of the part due to the outer metal wrinkles, but the rupture of the internal factor of the parts is generally required to be modified. Partial rounded and tilt angles to avoid.
Process incision is a common process method in the process of automobile covering parts, induction heating through the finite element numerical simulation of automobile mask frame parts, except that the pressure brakes are too large, the external metal wrinkles and internal florescence It will cause internal metals to create rupture, for the uncertainty of the process incision, the opening position and size need to be reasonable, the linear process incision is more effective than the round curved process incision is more effective than the round curved process incision, and the process incision is required. Pay attention to the radial tear at the corner, can be avoided with a large arc corner transition, ultimately obtaining a suitable process parameter by simulation, and is effective verification in production.
