frame type hydraulic pressFrame structure, good rigidity of the fuselage. The slider is guided by four corners and eight sides, with high adjustment accuracy and strong anti-deflection load capacity. Local slider down speedFast working surface, large working surface, anti-stretching function of upper sliding block and lower hydraulic pad, wide process range, can complete stretching, blanking, bending, flanging, etc. of metal sheetProcess. Especially suitable for the automotive industry, steel ring, body, axle housing, land, doors and other parts. So what is the downward speed of the frame hydraulic press related?
Rapid decline:
The lower oil cavity of the oil cylinder is directly connected to the oil tank, and the oil tank of the lower oil cavity and the oil of the upper oil tank are supplemented to the upper oil cavity. This process depends on the weight of the slider to drop, fast.
Slow Descent:
Lower oil cavity to go through the support valve after shu oil tank. (The support valve prevents the slider from sliding down)
At this time, the high-pressure oil coming from the upper oil chamber downward of the slider exceeds the pressure of the support valve and then goes downward, so it is slow.
When the sliding block of the frame hydraulic press is lowered into the working state by its own weight, the downward speed of the sliding block is related to the pressure of the master cylinder. If it is a valveless servo hydraulic systemsystem, the greater the pressure, the faster the downward speed. If it is an overflow valve, overflow, the speed slows down.
When the upper die of the frame hydraulic press is in contact with the lower die, it has an effect on the downward speed. If the die has a bottom dead center, the slider will stop. The new technology is the use of Kehui's opening.Reluctance servo motor drives the hydraulic pump, realizes the valveless servo hydraulic system, intelligent automatic numerical control, high efficiency and energy saving, high reliability.
