四柱液压机可用来进行薄板的拉伸、弯曲、成型等工艺。可进行落料、校正、压装、冲裁。适用于航空、汽车、拖拉机、机床、仪表、化工等行业。
结构特点:
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,压边动梁先下降,当压边动梁不在下降而变为保压状态。此时,拉伸动梁快速下行,接近工件时改为慢速进行拉伸。拉伸工艺完成后, 拉伸动梁可实现保压延时、缷压和快速回程,压边动梁相应也缷压回程,然后顶出缸将工件顶出。完成一个工作周期,是个 小型液压机。
产品简介:
四柱液压机的控制系统设有调整、半自动、连续循环三种工作方式。半自动和连续循环适于单动和双动拉伸两种工艺,在单动工艺中分6300KN和10300KN二种力级。液压控制系统采用了插装阀集成块。其高压泵采用 斜轴式变量泵,并设有液压油过滤、加热、冷却系统。电气控制系统采用了可编程序控制器,多种故障报警指示器和非接触式安全保护控制装置的红外光幕控制器可根据用户需要配备下液压垫、打料装置移动工作台、冲裁缓冲装置、光栅安全装置。
Product Profile:
The control system of four-column hydraulic press has three working modes: adjustment, semi-automatic and continuous circulation. Semi-automatic and continuous cycle are suitable for single-acting and double-acting stretching processes. There are 6300KN and 10300KN force levels in single-acting process. The cartridge valve integrated block is used in the hydraulic control system. Its high-pressure pump adopts oblique-axis variable displacement pump, and has hydraulic oil filtration, heating and cooling system. The electric control system adopts programmable logic controller. Infrared light curtain controllers of various fault alarm indicators and non-contact safety protection control devices can be equipped with hydraulic cushion, feeding device mobile worktable, blanking buffer device and grating safety device according to user's needs.
