我国首台20MN成型板冲压油压机于一九八七年三月三十一日在太重试制成功。经过总装试动,证明这台压机达到了设计要求。 20MN成型板冲压油压机为通用单动油压机,可以用来完成压弯、压筋、浅拉伸校平、局部成型及冲裁等冷冲压工艺,适用于长度不超过四米、宽度不超过二米、厚度四至十六毫米的大型板冲压件生产,对较厚板也可用于热压成型,特别适合于铁道车辆板件与汽车复盖件的冲压生产。设备由压机本体、液压传动和电气控制装置等组成。其中压机本体采用了优化设计的框架结构,工作走台采用了液压锁紧,液压传动采用了组合锥阀,压机工作时通过压力吨位显示,使压机在加压过程中可随肘
China’s first 20MN forming plate stamping hydraulic press on March 31, 1987 in too heavy trial success. After the assembly trial move to prove that this press has reached the design requirements. 20MN forming plate stamping hydraulic press is a universal single-action hydraulic press, which can be used for cold stamping process such as bending, crimping, shallow drawing, partial forming and blanking. It is suitable for length less than four meters and width less than two meters , The thickness of four to sixteen millimeters of large-scale production of sheet metal stamping, the thicker plate can also be used for hot-forming, especially suitable for rail vehicle panels and automotive cover pieces of stamping production. Equipment from the press body, hydraulic transmission and electrical control devices and other components. The main body of the press adopts the frame structure with optimized design. The working platform adopts the hydraulic locking, the hydraulic transmission adopts the combination cone valve, the pressure is displayed by the pressure tonnage when the press is working, so that the press can press the elbow
