封头拉伸流程图
Large head hydraulic pressThe flow chart of stretching motion is shown in the above figure. State 1 is the initial position of the hydraulic press. State 2 is that the stretching slider and the holder slider quickly approach the workpiece together under the drive of the stretching cylinder. State 3 is that the stretching slider does not move. The holder slider moves down the holder ring to press the workpiece. State 4 is that the holder slider does not move (with holder force). State 5 is that the stretching slider and the holder slider move back to push the holder back to lift the workpiece.
The process flow is as follows: the initial position of the hydraulic press → the stretching slider and the pressing slider are quickly lowered together → the pressing slider is quickly lowered separately → the pressing slider is pressurized → the stretching slider is downward to stretch the workpiece → the pressure holding delay and pressure relief → the pressing slider is returned → the lifting rotating device is lifted up → (after the workpiece is removed) the lifting rotating device is returned. The ejection starting time of the jack-up rotary device can be excited by the position set in the return stroke of the slider to increase the working frequency.
Shandong Zhongyou Heavy Industry Machine Tool Co., Ltd. can customize various tonnage cold/hot pressing head stretching hydraulic presses according to the actual needs of customers. The body of the head stretching hydraulic press adopts a four-column or pre-tightened split frame structure. General forming parts of the head stretching hydraulic press with four column, simple structure, economical and practical, four column oriented. The head part with high precision requirements adopts prestressed frame structure and is guided by four-angle and eight-sided plane guide rail, which has high guiding precision and strong anti-deflection load capacity.
