What is the reverse stretching process of 2000 tons hydraulic press?

 

Stretching as one of the main processes of stamping, has been widely used, especially in the field of auto parts forming, often used in the stretching process and anti-stretching process, below we use 2000 tonsHydraulic pressAs an example, the machine reverse stretching process is introduced.

2000-ton hydraulic press reverse stretching is also called reverse stretching, which refers to the process of reverse stretching the stretched workpiece in the previous process, turning the inner side of the workpiece into the outer side and making its outer diameter smaller. The reverse stretching method can increase the radial tensile stress and has a good effect on preventing wrinkling. It is also possible to increase the stretch coefficient of re-stretching.

 

　　2000吨液压机做拉伸工艺时采用的是主油缸加下顶缸结构，主油缸将拉伸材料的边压住，然后由下顶缸进行往上顶，使工件完成反拉伸工艺，本结构液压机经济实惠，性价比高，客户前期投资成本少，回本周期短，具体技术方案可以咨询山东众友重工丁经理13562463338（同微信号），免费提供详细技术方案。

 

　　我们生活中常见的拉深制品比如脸盆、铝锅、饭盒、汽车油箱、汽车覆盖件等都需要用到金属件拉伸液压机。金属件拉伸液压机主要用于板材的深拉伸工艺，其中双动拉伸液压机拥有内外两个活动横梁：拉伸动梁和压边动梁，工作时两者可以同时快速下降，模具靠近时开始慢速下降进行合模，然后开始保压。
