Precision metal stamping parts manufacturers, how to solve the material rebound + the overall solution of precision stamping parts

Hardware is one of the manufacturers of precision metal stamping parts. For now, our country's automobile mold industry is developing rapidly, but the talents and skills of mold designers have not kept up. As far as the rebound is a headache, no one dares to say that he can perfectly solve the rebound problem, but this problem has always existed, and it is a topic that we need to discuss. Xiaoshuo has been engaged in the mold design industry for many years, and has summarized some experience for your reference: 　　1. Material The structure of the car is complex, and there are many kinds of parts. There are many stamping parts of different strengths on the car body, from ordinary plates to high-strength plates. Different yield strength, the greater the yield strength of the sheet, the easier it is to rebound. 2. When the material thickness is formed, the material thickness has a great influence on the molding. With the change of the material thickness, the springback phenomenon will change accordingly, mainly because the plastic deformation becomes difficult with the change of the material thickness. , Resulting in smaller rebound. 3. The springback of products with different product shapes is also different. Products with complex shapes will basically undergo a step to prevent springback due to improper forming. Some special products are more prone to springback, such as U-shaped products. In the analysis and forming, it is necessary to think about springback compensation.　　4. Product blank holder force 　　 blank holder force plays a vital role in forming. By properly adjusting the blank holder force, the direction of movement of the material can be adjusted and the internal stress distribution of the material can be improved. The increase of blank holder force can make the product drawing more fully, especially the part side wall and the R angle position. If the forming is sufficient, the internal and external stress difference will increase, thereby reducing the springback. 5. Drawbeads Drawbeads are commonly used in today's processes. A reasonable setting of the drawing position can effectively change the direction of material movement and effectively distribute the feed resistance on the pressing surface, thereby improving the material formability. Setting drawbeads on parts that are prone to springback will make the parts more fully formed, the stress distribution will be more uniform, and the springback will be reduced. Hardware, 15 years of focus on precision metal stamping parts manufacturers, 5000 square meters production workshop, hundreds of precision processing production equipment, more than 20 Ru0026D and design engineers, monthly 100+ sets of mold processing capacity and daily production capacity of 3 million punching times, stamping accuracy can be Up to 0.01mm, 16 quality inspection layers are strictly checked. It can quickly solve the urgent problem of time when choosing hardware stamping processing, solve the problem of stamping accuracy, and solve the problem of production quality. For 15 years, I have been conscientious and dedicated to the results of your needs for the results of work!
