double-acting sheet stretching hydraulic pressUse
Mainly used in the deep drawing process of plates, such as the manufacture of various containers and large automobile covers,
双动拉伸液压机的主要结构特点是有内外两个活动横梁，拉伸动梁装在里面，压边动梁装在外边。在进行双动拉伸的时候，拉伸动梁和压边动梁可一起快速下降，接近工件时改为慢速下降，当压边动梁压住工件四周时，压边动梁不在下降而变为保压状态。此时，拉伸动梁继续下行进行拉伸。拉伸工艺完成后，拉伸动梁可实现保压延时、卸压和快速回程，压边动梁相应也卸压和快速回程，然后液压垫和顶杆将工件顶出
In addition to the hydraulic pad (ejector) and ejector rod, the stretching hydraulic press is also equipped with a mobile workbench to facilitate the replacement of large molds.
The double-action stretching hydraulic press can also connect the stretching and edge-holding moving beams into one body through positioning pins or pull rods to realize single action. At this time, the pressing force will make the sum of the two.
