high precision hand crank press crankshaft press
In mechanical presses and hydraulic presses, when the sheet is stretched, the stretching pad is used to hold and hold the stretch members to avoid wrinkling the stretch members. In the meantime, the stretching pad is used as a feeder for returning the slider
By introducing of the world's advanced technology, our company developed MP Series Hot Forging Press. MP Series Hot Forging Press is widely used in areas of : automobile, tractors, internal combustion machinery,ship, aviation, mineral machinery, petroleum machinery, hardwares and tools.also used in the forging and precise trimming of bulk ferrous and non-ferrous metals.
This series machine has following advantages:
2.high utilization of material
5.low noise and light vibration
In mechanical presses and hydraulic presses, when the sheet is stretched, the stretching pad is used to hold and hold the stretch members to avoid wrinkling the stretch members. In the meantime, the stretching pad is used as a feeder for returning the slider, and the stretching member is sent to the conveying surface. Advanced stretching device using hydraulic or pneumatic control. The biggest difference between these two control methods is that the hydraulic pressure is greater than the pressure type. Hydraulic tension device is the force of the slider under pressure, the force from the four hydraulic cylinders through the lower slider and mandrel spread to the mold blank holder corners.
hand crank press Stretch pad After the slider reaches bottom dead center, it can be an uncontrolled return stroke, in which case the stretching pad returns with the slider. Or a controlled return, ie after reaching the preselected standstill, the stretching pad is pushed by the lift cylinder in the center of the lifting beam for a delayed return. At the same time, the end point cushioning using proportional valve control technology ensures that the tension pad returns to top dead center without vibration.
