What are the requirements of the hydraulic press for the column

Because the use of hydraulic press is generally more, it is also very large for the damage to the column. Therefore, when we choose a hydraulic press, we should also choose a good column, and choosing a good column is a very important parameter. So what are the requirements of the hydraulic press for the column? Here is to introduce the requirements of the hydraulic press for the column.

First, repeated deep stress is too large, that is, fatigue damage is generally referred to, and the place of repeated load should be calculated, and the repeated force of high strength for a long time will produce cracks

Second, the stress concentration area, in the place where the bending moment is larger, mainly at the nut connecting the lower beam

Load and centrifugal force; The damage of the column will not be suddenly broken by force, it is after hundreds of thousands of times of repeated force, and then a crack is generated, extending from the crack

Fourth, because there is no typical load scheme, the most effective calculation method for fatigue design has brought difficulties, in the calculation of the bearing capacity of the column, a large part of it is based on experience, so it is detailed and clear when explaining to technical personnel.
