Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, and particularly relates to a servo hydraulic press for preventing leakage in the production of automobile interior parts. Background Art

[0002] A hydraulic press is a machine that uses liquid hydrostatic pressure to process products such as metals, plastics, rubbers, woods, and powders. It is commonly used in the pressing and forming process. During the process of pressing and forming products, a hydraulic press generally uses a hydraulic cylinder as the driving component. A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and makes a linear reciprocating motion (or swinging motion). Its structure is simple and its operation is reliable. When using it to achieve reciprocating motion, a speed reduction device can be omitted, and there is no transmission gap, and the motion is stable. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] However, in the prior art, traditional hydraulic presses usually use simple sealing rings at the interfaces to solve the problem of hydraulic oil leakage. However, under the long-term friction of the hydraulic rod, the sealing rings are worn, resulting in hydraulic oil leakage. At the same time, the sealing parts are vulnerable parts. Therefore, if the sealing parts cannot be replaced quickly when replacing them, the working efficiency of the hydraulic press will be affected. Summary of the Utility Model

[0038] Working principle:

[0039] In use, first install the seal to the upper cover 59 in the sealing mechanism 5. A round hole 52 is provided in the upper cover 59. At this time, quickly connect the ring 56 to the round hole 52, and at the same time snap the sealing ring 54 into the corresponding slot. In the circular slot in the upper cover 59, there is also a slot. At this time, install the outer retaining ring 57 and the inner retaining ring 58 into the slot. First, insert the hydraulic column 6 into the circular slot. After the hydraulic column 6 is installed, install the hydraulic column 6 and the piston 7 into the cylinder block 1. Then place the upper cover 59 above the retaining ring 510 and align the upper cover 59 with the retaining ring 510. After the upper cover 59 is aligned, press and fit the upper cover 59 and the retaining ring 510, forcing the sealing block 55 on the retaining ring 510 to contact the ring 56, and at the same time the top ring 53 fits the sealing ring 54. After the retaining ring 510 and the seal on the upper cover 59 are fitted, use the quick-connect mechanism 4 to install the upper cover 59 on the retaining ring 510.

[0040] A hook plate 41 is fixed on the upper cover 59, and a fixing plate 43 is fixed on the retaining ring 510. Therefore, by rotating the pull plate 45 on the fixed block 47, the pull plate 45 is forced to drive the pull rod 42 to move. At this time, slide the pull rod 42 into the hook plate 41. At this time, rotate the pull plate 45 in the reverse direction. Under the rotation of the pull plate 45, the pull rod 42 is forced to drive the hook plate 41 to move, thereby forcing the upper cover 59 to move synchronously. And the quick-connect mechanism 4 is arranged in a circular array along the central axis of the cylinder block 1. Therefore, the upper cover 59 is driven to move by the quick-connect mechanism 4, forcing the upper cover 59 to closely adhere to the retaining ring 510. A limiting groove 46 is provided on the pull plate 45, and a limiting block 44 is fixed on the fixing plate 43. Therefore, the limiting groove 46 of the pull plate 45 is stuck on the limiting block 44 to fix the pull plate 45, so as to fix the pull plate 45, making the quick-connect mechanism 4 continuously fix the upper cover 59 and the retaining ring 510.
