Advantages and characteristics of four-column hydraulic press forming technology


1. Reduce quality and save data. For typical parts such as car engine brackets and radiator brackets, hydroforming parts are 20% to 40% lighter than stamping parts; for hollow stepped shaft parts, the weight can be reduced by 40% to 50%.



2. Reduce the number of parts and molds and reduce mold costs. Hydroforming parts generally only require one set of molds, while most stamping parts require multiple sets of molds. The hydroformed engine bracket parts were reduced from 6 to 1, and the radiator bracket parts were reduced from 17 to 10.










3. It can reduce the amount of welding for subsequent machining and assembly. Taking the radiator bracket as an example, the heat dissipation area is increased by 43%, the number of solder joints is reduced from 174 to 20, the number of processes is reduced from 13 to 6, and the productivity is increased by 66%.



4. Improve the strength and stiffness, especially the fatigue strength. For example, the stiffness of the hydroformed radiator bracket can be increased by 39% in the vertical direction and 50% in the horizontal direction.



5. Reduce production costs. According to the statistical analysis of used hydroformed parts, the production cost of hydroformed parts is evenly reduced by 15% to 20% compared with stamping parts, and the cost of molds is reduced by 20% to 30%.
