Deep Drawing Double Action Hydraulic Press 500 Ton Capacity Large Flow Rate

YZ32-200Ton Sheet Metal Deep Drawing Hydraulic Press Machine for headcover can also be used for rectification, pressing, packing, pressing and pressing, as well as for shaft parts, profile calibration, buckling, pressing and assembling, as well as sheet parts bending, debating, setting, stamping, sleeving, stretching, plastic materials pressing process, such as stamping, bending, flanging thin stretching, etc. It can also be used for correcting, pressing, plasticizing, etc. Material products and powder products are also called universal hydraulic press because of their wide range of applications.

The working principle of each cylinder of headcover hydraulic press is almost the same. Taking a manual Jack as an example, the jack is actually the simplest cylinder. By means of manual booster stem (hydraulic manual pump), hydraulic oil enters the cylinder through a one-way valve. At this time, the hydraulic oil entering the cylinder can no longer retreat because of the reason of the single valve, forcing the cylinder rod upward, and then continuously making the hydraulic oil enter the hydraulic cylinder, thus continuously rising, turning over the hydraulic valve to make the hydraulic oil return to the tank in the time of falling. This is the simplest way. Slightly operating principle, the other are improved on this basis, the principle of cylinder and cylinder is basically the same.

Headcover hydraulic press's empty and return journey can be high-speed, and the speed of operation journey can be adjusted according to the need. When switching from operation journey to return journey actively, it can be controlled by stroke orientation or hydraulic press effect force, and it can also be switched after a predetermined effect force is applied. Operating forms include active stroke, single stroke and inch movement. The hydraulic press can be equipped with blank initiative feeding, workpiece initiative transmission between workstations and forging initiative unloading organization. The number of ejectors in the worktable can be regarded as single or multiple units to equip. Filling valves are used in large and medium-sized hydraulic presses. The cylinders of these equipments are large and only supplied by oil pumps. The downward speed is too slow, which affects the output power. An upper tank is set on the top of the press. A filling valve is installed between the upper tank and the upper chamber of the cylinder. When the piston is lowered, the filling valve opens and the oil of the upper tank is directly filled into the upper chamber of the cylinder. When pressurized, the filling valve closes and is pressurized by the oil pump. . When the piston rises, the filling valve opens and the oil in the upper chamber of the cylinder returns to the upper tank.

The filling valve of headcover hydraulic press can also set pre-open pressure and has reliable sealing function. It is widely used in forging and pressing machinery of hydraulic press. It can make the cylinder of hydraulic press play the effect of rapid filling and discharging oil. At high pressure and large flow rate, it can play the effect of unloading and avoid unloading impact. Filling liquid is usually used as suction and discharging valve between hydraulic pressure and oil tank, and it is a rapid postponement of large press. When it comes to time, the cylinder needs a lot of oil to make up for it, so it is advisable to absorb oil from the tank; when slowly entering pressure, it is necessary to avoid the oil from the reverse of the cylinder to the tank; when reversing, the oil can be discharged back from the cylinder to the tank. Processing is exquisite, fine height, no leakage, excellent pressure-holding function, itself to slow down the spool, can effectively reduce the sound and vibration. It is widely used in high-speed punch, press, injection machine and other machines.
