Car line stampings, metal stamping parts products springback problem, to master the five methods
Development of modern society more and more quickly, convenient transportation is more and more, the car is now one of the most common means of transport, so the demand of auto line stamping is also very big, the car line stamping parts production, the design will meet product springback problem, is very headache, the author summarizes some experience, and everyone to share: a, car line stamping material: the complex structure of the bus parts, these parts are made from different materials stamping or take other technology, and the intensity of automobile stamping parts by the different pipeline of sheet metal stamping, plate yield strength is big, the easier the springback problem;
Stamping parts raw material thickness: thick material itself will have an impact on the forming and springback phenomenon change, plastic deformation difficult products, product springback become smaller;
Three, mould blank-holder force: mould blank-holder force has very important role in product forming, through appropriate adjustment, can improve the internal stress distribution of the material, can make the product drawing more fully, so that the springback decrease;
Four, car line stamping shape: shape more complex product in the subsequent process generally increase the plastic process, prevent the forming of the springback, so when they need to consider the design characteristics of the special product, considering springback remedial process;
Five, the product drawing: reasonable design product drawing, can effective allocation of material feeding resistance, increase plastic products, uniform pressure distribution can make the springback smaller.
