In the process of press installation , it should be noted that the four adjustment nut for the table of the contour, so that the machine has a better basis for the adjustment of precision. In the pressurized state, the living wall with the activities of the beam connected parts fasten into a whole, at the same time, also the cylinder and the upper part of the beam is fastened. And then tighten the lock nut below the table as far as possible (in the case of no load), so that the next step can be adjusted precision work.
In the precision adjustment, the lower plane of the movable beam is perpendicular to the piston rod (single piece of machining accuracy is guaranteed, and at the same time, in the pressurized state, locked and integrated into a whole), so that the movable beam is flat and parallel to the work surface Deviation, can reflect the piston center line on the work surface of the vertical situation. Therefore, the movable beam can be left in the middle position, and the parallelism deviation is measured first.
Before adjustment, loosen the four locking nuts on the upper beam. Use the dial gauge to check the parallelism of the plane under the beam and the front and back of the plane on the table. If it is not required, tighten or loosen the front (left) two adjustment nuts, or the rear (right) adjustment nuts under pressure, and adjust the adjustment again until it meets the requirements. Before and after (left and right) parallelism meet the requirements, and then use the above method to adjust the left and right (before and after) parallelism. To be in the middle position to meet the requirements, but also check the activities of the beam in the dagger under the two positions of parallelism is in line with the requirements. When it is found that the parallelism between the upper and lower positions exceeds the requirements, and the measurement data in the opposite direction, should consider checking the assembly and checking the activities of the beam and other parts of the accuracy of a single piece to meet the requirements.
After the parallelism check is completed, check whether the movable beam of the movable beam meets the requirements. When the request is not met. The adjustment method is the same as the method of adjusting the parallelism until it meets the requirements. Similarly, when the accuracy of the vertical adjustment of the accuracy and parallelism of the accuracy contradictions, and the value is greater than the specified value, should check the assembly quality and inspection activities such as parts of the beam quality.
Parallelism and verticality are in line with the requirements, should lock the lock nut, at the same time, check in the case of no load Whether the adjustment nut with the beam fit, should not be loose. If the loosening is found, the accuracy adjustment is unreliable and the accuracy should be readjusted. Precision adjustment is reasonable,which is one of the main measures to extend the service life of the press to prevent unnecessary wear and tear of . So the accuracy of the press should be regularly checked, regular adjustment is necessary.
Similarly, the quality is the premise described above, in the purchase of presses ，we should pay attention to brand effect, choose large brands, high reputation of the production manufacturers, such as Zhengzhou Haloong Machinery Manufacturing Co., Ltd. focused on the production and development of presses excellent enterprise.
