Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic press material return, in particular to an automatic induction material return device for a hydraulic press. Background Art

[0002] The operating principle of a hydraulic press is based on Pascal's law, which states that pressure in a closed system is transmitted evenly in all directions. When pressure is applied to a liquid, it is transmitted to every point throughout the system. In a hydraulic press, a hydraulic pump pumps fluid into a master cylinder, generating pressure that is then evenly transmitted to smaller slave cylinders. Due to the difference in area, the slave cylinders generate greater force, thus completing the work.

[0003] When the hydraulic press completes pressing the material, it usually needs to be returned. However, the existing devices mainly use manual material return, which has low installation efficiency. Some automatic material return devices cannot return materials of various shapes, and have high limitations. Utility Model Content
