The principle of internal high pressure forming technology, the principle of internal high pressure forming is to press the tube blank into the mold cavity through internal pressure and axial force to form the required workpiece. For parts with bending axes, the tube blank needs to be pre-bent into a shape close to the part, and then pressed into shape.
The advantages and application of internal high-pressure molding technology, the internal high-pressure molding parts are light in weight, good product quality, flexible product design, simple process, and has the characteristics of near-net molding and green manufacturing, so it has been widely used in automobile lightweight. Through effective cross-sectional design and wall thickness design, many automotive parts can be made into a single integral part with complex structure from standard pipes through internal high-pressure molding. This is clearly superior to the traditional stamping welding method in terms of product quality and production process simplicity. Most hydroforming operations only require a punch (or hydroforming punch) that conforms to the shape of the part. The rubber diaphragm on the hydroforming machine acts as a common mold, resulting in a mold cost that is about 50% lower than traditional molds. Compared to traditional stamping, which requires multiple steps, hydroforming can form the same part in one step.
Compared with stamped welded parts, the advantages of pipeline hydroforming are: saving materials and reducing weight, general structural parts can be reduced by 20% ~ 30%, and shaft parts can be reduced by 30% ~ 50%: such as automobile subframe, general stamping parts weigh 12kg, internal high-pressure molded parts weigh 7-9kg, and weight 34%. Processing capacity and assembly welding workload; improve the strength and rigidity of the components, and improve the fatigue strength due to the reduction of solder joints. Compared with stamping and welding parts, the material utilization rate is 95% ~ 98%, and the production cost and mold cost are reduced by 30%.
The above article content is for all friends to introduce the relevantInternal high pressurePoints to understand. Friends can read it carefully. Of course, there is still a lot of information related to internal high pressure. We will continue to update later. There are still places you don't understand that you can come to consult at any time. Then when you purchase, we also suggest that you find regular and powerful manufacturers. In this case, the price is also guaranteed. The enterprise has effectively guaranteed the usability of the internal high pressure, so it is all trustworthy. If consumers want to buy this type of product, remember to shop around. This is an era of information technology. There is no need for everyone to go to the market and work hard. You can directly search for relevant manufacturers on the Internet.
