The Supply Margin Of The C Frame Press

his transmission system is small, simple structure, the pressure can automatically increase or decrease according to the required work force, reducing the power consumption, but by the maximum working force of the hydraulic press and the maximum working speed to determine the pump and its transmission motor capacity. This type of transmission system for small and medium-sized hydraulic press, but also useful pump direct drive large (such as 120000 kN) free forging hydraulic press. Pumps - Accumulator drives have one or a group of accumulators in this drive system.C Frame Press

When the high-pressure working fluid supplied by the pump has a margin, it is stored by the accumulator, and when the supply amount is insufficient, it is supplied by the accumulator. The use of such a system can be used according to the average amount of high pressure working fluid pump and motor capacity, but because the working fluid pressure is constant, hydraulic jack, power consumption is large, and the system links, the structure is more complex. This drive system is used for large hydraulic presses, or with a set of transmission system drive several hydraulic press.C Frame Press

In the vertical four-leg free forging hydraulic press, the cylinder is fixed in the upper beam, the plunger is connected with the movable beam, and the movable beam is guided by the column, and moves up and down under the pressure of the working fluid. There are tables on the beam that can be moved back and forth. Install the anvil and the anvil separately under the movable beam and the work surface. The working force is borne by the upper and lower beams and columns. The use of pump - accumulator driven large and medium free forging press often used three working cylinders to get three levels of work force. The cylinder also has a counterweight and return cylinder that exerts a force upward.C Frame Press

Before the circuit breaker is ready for operation, check each part of the circuit breaker once. Such as the various parts of the solid bolts are strong, the transmission part is normal, the magnet face rust-free grease is wiped, so as not to affect the system action value.C Frame Press
