internal high pressure hydroforming production line
Advantages and Applications
The droforming component has light weight, good product quality, flexible product design, simple process, and has the characteristics of near-net forming and green manufacturing, so it has been widely used in the field of automotive lightweight. Through effective section design and wall thickness design, many auto parts can be formed into a single integral component with complex structure by droforming of standard tubes. This is obviously much superior to the traditional stamping and welding method in terms of product quality and simplicity of the production process. Most droforming processes require only a punch (or droforming punch) that is consistent with the shape of the part, and the rubber diaphragm on the droforming machine plays the role of the usual die, so the die cost is about 50% less than the traditional die. Compared with the traditional stamping process, which requires multiple processes, droforming can form the same part in just one step.
Compared with stamping welding parts, the advantages of pipe droforming are: saving materials, reducing weight, general structural parts can be reduced by 20% ~ 30%, shaft parts can be reduced by 30% ~ 50% : Such as car subframe, the general weight of stamping parts is 12kg, internal high pressure forming parts are 7 ~ 9kg, weight reduction of 34%, radiator support, general stamping parts weight 16.5kg, internal high pressure forming parts are 11.5kg, weight reduction of 24%; Can reduce the amount of subsequent machining and welding workload; Increase the strength and stiffness of the component, and increase the fatigue strength due to the reduction of solder joints. Compared with the welding parts, the material utilization rate is 95% ~ 98%; Reduce production costs and mold costs by 30%.
droforming equipment is suitable for manufacturing aerospace, nuclear power, petrochemical, drinking water system, pipe system, automotive and bicycle industries of complex shaped section hollow components . The main products in the automotive field are automobile body support frame, auxiliary frame, chassis parts, engine support, intake and exhaust system pipe fittings, camshaft and other parts.
