The flat forging press manufacturer tells you that the sudden load loss of the press refers to the sudden decrease or disappearance of the deformation resistance of the material in the process of cold stamping, blanking, trimming, and blanking, which causes the body of the single-row press to produce greater shock and vibration. Flat forging press manufacturers tell you that in severe cases, the anchor rod will break, or even the beam will break, and the foundation will be damaged. So, how to solve the load loss of the press? Shall we go to the punch factory?
1. Reduce the storage of liquid elastic energy. The flat forging press manufacturer tells you that the elastic energy of the liquid storage tank is proportional to the height of the liquid in the working cylinder. Therefore, the backing plate can be thickened between the working table and the lower die of the press, so that the working stroke of the movable beam moves upward, and the liquid level of the working cylinder is reduced. In addition, a movable block is added between the piston of the working cylinder and the movable beam, that is, when the idle stroke of the press of the press factory drops, the piston and the movable beam descend together. The flat forging press manufacturer tells you that after touching the workpiece, the piston first returns and rises before pressurizing. At this time, the hydraulic cylinder assists the work, and the movable pad is inserted between the piston and the movable beam. When working, the piston descends again, and the movable crossbeam is pressed down by the spacer block to carry out punching loading, trimming and other processes to reduce the solvent in the upper cavity of the working cylinder.
2. The flat forging press manufacturer tells you another way to release energy, that is, when the press suddenly loses load, part of the high-pressure liquid in the working cylinder is quickly discharged from the side to reduce the released energy. When the liquid pressure is higher, this method is more effective, but the corresponding electro-hydraulic control valve should have higher sensitivity and should not cause large vibrations in the side drain pipeline.
3. Absorb energy and vibration. There is no cushion under pressure. The flat forging press manufacturer tells you that when the material is about to be cut, the moving parts will contact the pressure pad at the moment of cutting, so energy will be consumed on the pressure pad. The cushion can be a hydraulic shock absorber or a gas-liquid shock absorber. The flat forging press manufacturer tells you that because the resistance of the cushion to the movable beam is after the shear force reaches a certain value, there is no need to increase the pressure of the press.
The above is the method that the Flat forging press manufacturer told you to solve the load loss of the press. I don’t know if everyone knows it. There are more news and information. Please continue to pay attention to the website. We will update the relevant information from time to time for your reference.
