Box - Pressing Mode Of H Frame Press

In this drive system there is one or a group of accumulators. 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. This 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, the 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 drive system to drive several hydraulic press.H Frame Press Structural type by the direction of force to distinguish between the hydraulic machine has two vertical and horizontal. Most hydraulic press is vertical, hydraulic press is more horizontal with horizontal. According to the structure type, the hydraulic machine has the double column, the four pillars, the eight pillars, the welding frame and the multi-layer steel strip winding frame and so on, the medium and the small vertical hydraulic press also uses the C type frame type. C-type hydraulic press on three sides open, easy to operate, but poor rigidity. Stamping with the welding frame hydraulic machine rigid, open before and after, but left and right closed.H 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.H Frame Press
