Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic press working platforms, in particular to an anti-eccentric load hydraulic press working platform. Background Art

[0002] The four-column hydraulic press work platform is a mechanical equipment that uses the static pressure of hydraulic oil delivered by the oil pump to process metal, plastic, rubber, wood, powder and other products.

[0003] During the use of the existing four-column hydraulic press, the steel pipe to be straightened needs to be placed on the hydraulic platform for straightening. When the hydraulic plate squeezes the steel pipe downward, the operator needs to hold the steel pipe to cooperate with the straightening process. The safety factor of this process is too low, and the operator is very likely to cause safety accidents during the process of holding the steel pipe. At the same time, the fixing force provided by the manual support method is relatively limited, which affects the normal straightening quality of the steel pipe. Therefore, improvements are needed;

[0004] The existing patent (publication number: CN210280266U) discloses a four-column hydraulic press, comprising a hydraulic platform and four supporting columns vertically and parallelly arranged on the hydraulic platform. The upper ends of the four supporting columns are fixedly connected to a supporting plate, a hydraulic cylinder is provided on the upper surface of the supporting plate, and a hydraulic cylinder output end is connected to a hydraulic rod. One end of the hydraulic rod passes through the supporting plate and is connected to the hydraulic plate. A pre-positioning platform is provided on one side of the hydraulic platform. The horizontal height of the upper surface of the pre-positioning platform is equal to the horizontal height of the upper surface of the hydraulic platform. A rotating groove is provided on the upper surface of the pre-positioning platform. A rotating disk is provided for rotating in the rotating groove. The upper surface of the rotating disk is symmetrically provided with a fixed plate and a movable plate for cooperating in squeezing and fixing steel pipes. A driving and moving component for driving the movable plate to move relative to the fixed plate is provided on the upper surface of the rotating disk. A rotating driving component for driving the rotating disk to rotate is provided on the pre-positioning platform. The utility model provides a four-column hydraulic press with high safety factor, mechanized positioning of steel pipes and simple and convenient operation.

[0005] In response to the above problems, the existing patents have provided solutions. However, when the existing four-column hydraulic press working platform is in use, although its own structure has the function of preventing unbalanced loading, the hydraulic oil inside it will deteriorate during long-term use, and the impurities inside it may clog the hydraulic valves and oil pipes, affecting the normal flow of the hydraulic oil, causing the oil cylinders to work asynchronously and produce unbalanced loading. However, the existing four-column hydraulic press working platform does not have a hydraulic oil auxiliary detection structure, which makes the user's hydraulic oil quality detection process more cumbersome, and the four-column hydraulic press working platform is in a shutdown state during detection, so that the hydraulic oil inside it is in a static state, resulting in the hydraulic oil sampled by the user at a fixed position being not comprehensive enough and unable to help the user determine the quality of the hydraulic oil. The existing patents cannot solve this problem, so it is not conducive to user use.
