            How to adjust the parallelism of four column hydraulic press?

            When the piston assembly of four column hydraulic press works, there are two different kinds of vibration. This may be due to a fault in the balance circuit of the equipment. For four column hydraulic press, how to solve it quickly and effectively? In order to adjust the parallelism of the hydraulic press, it is necessary to adjust the parallelism between the slide block and the worktable by adjusting the nut of the upper crossbeam to adjust the accuracy of the machine. Next, adjust the device to the pressurized state, fix the connection part of the movable beam and the movable beam, and then connect the whole beam. At this time, the connection between the oil cylinder and the upper beam must also be fixed. In this case, the locking nut must be tightened under the hydraulic press table as far as possible, so that the parallelism of the hydraulic press can be judged from the parallelism between the lower surface of the movable beam and the piston rod. More accurate results can be obtained by using the press only in two vertical states.
            In the opinion of experts, it is not complicated and difficult to adjust the parallelism of four column hydraulic press. To successfully complete the task, you only need to acquire relevant expertise. In addition, when adjusting the parallelism of the hydraulic press, a certain pressure is required in the adjustment process. Therefore, after removing the mold, the slider can not slide down, and pressure resistant parts of the same level should be placed.
            Before adjusting the four column hydraulic press table, loosen the four lock nuts on the upper beam. The dial indicator first checks the parallelism between the bottom plane of the movable beam and the front and rear (left and right) planes of the table. If not, pressurize and tighten or loosen the two front (left) adjusting nuts or the two rear (right) adjusting nuts until
            The measurement and adjustment meet the requirements. Once the front and back (left and right) parallelism meets the requirements, please use the above method to measure and adjust the left and right (front and back) parallelism. After the middle position meets the requirements, check whether the parallelism of the movable beam at two positions below the dagger meets the requirements. If the parallelism deviation of the vertical position exceeds the requirements, and the direction of the measured data is opposite, please check the assembly status and check whether the accuracy of individual items such as movable beam meets the requirements.
