Description

Technical Field

[0001] The present application relates to the field of automotive parts processing, and more particularly to a four-column hydraulic press for automotive parts processing. Background Art

[0002] A four-column hydraulic press, also known as a hydraulic press, is a machine using liquid pressure transmission made based on Pascal's law. It processes products such as metals, plastics, and rubbers by using the static pressure of hydraulic oil pumped by an oil pump, and is commonly used in the pressing process and press forming in automotive parts processing.

[0003] The patent document with the publication number CN218463032U discloses a four-column hydraulic press for automotive parts processing, including a workbench. Four sliding channels are provided on the upper end surface of the workbench. When in use, through the four spring pressing devices provided, when using the four-column hydraulic press to process automotive parts and it is necessary to replace the lower mold of the parts, by pulling the pressing block, the pressing block drives the spring fixing block to slide in the installation groove under the action of the slider, compressing the pressure spring, so that the pressing block disengages from the lower mold. Only by pulling the two spring pressing devices apart can the lower mold be taken out from the workbench. Then, place a new lower mold on the workbench and adjust it to the appropriate position. After that, release the spring pressing device, and under the action of the pressure spring, the pressing block will squeeze and fix the side of the new lower mold, achieving the purpose of facilitating the replacement of the lower mold.
