Description

Technical Field

[0001] The utility model relates to the field of hydraulic press accessories, and specifically relates to a two-way flange for the end of a hydraulic pipeline of a hydraulic press. Background Technique

[0002] A hydraulic press is a two-way flange for the end of a hydraulic pipeline of a hydraulic press that uses liquid as the working medium.

[0003] The publicly disclosed Chinese patent No. CN211738330 discloses an elbow flange for a hydraulic pipeline of a hydraulic press, which includes a steering block in a cuboid structure, and an L-shaped flow cavity is arranged inside the steering block; flange plates are fixedly arranged on the end faces of the steering block at both ports of the flow cavity; a circular ring protrusion is arranged on the side of the flange plate opposite to the steering block, and a clamping groove that cooperates with the circular ring protrusion is coaxially arranged at the port of the flow cavity; a first clamping groove is arranged on the outer side wall of the circular ring protrusion along the circumferential direction, and a first sealing ring is arranged between the inner wall of the first clamping groove and the inner wall of the clamping groove. During the use of the utility model, even if vibration causes the connection between the flange plate and the end face of the steering block to become loose, the circular ring protrusion can only move axially along the clamping groove. During the axial movement of the circular ring protrusion, the first sealing ring is still pressed between the circular ring protrusion and the inner wall of the clamping groove. Therefore, the first sealing ring can still ensure the sealing of the flow cavity and will not cause hydraulic oil leakage. However, the following problems still exist in the actual use of this patent:

[0004] The elbow flange for the hydraulic pipeline of the hydraulic press is connected through the flange plate and the end face of the steering block. However, during use, only a single-direction connection is made between the flange plate and the steering block through bolts. During the operation of the hydraulic press, the vibration is likely to cause the bolts at the connecting flange to become loose. When the oil pressure is relatively high, it is still easy for hydraulic oil to leak from the gap between the flanges, resulting in a decrease in the hydraulic oil pressure and posing a safety hazard to the connection of the flange at the end of the hydraulic pipeline. Therefore, the practicality of this two-way flange of the hydraulic pipeline is relatively poor.

[0005] A two-way flange for the end of a hydraulic pipeline of a hydraulic press is proposed to solve the problems mentioned above. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a two-way flange for the end of a hydraulic pipeline of a hydraulic press, so as to solve the problem proposed in the above background technology that at present, the elbow flange for the hydraulic pipeline of the hydraulic press is connected through the connection between the flange plate and the end face of the steering block. However, during use, only a single-direction connection is made between the flange plate and the steering block through bolts. During the operation of the hydraulic press, the vibration generated is likely to cause the bolts at the connection flange to become loose. In the case of relatively high oil pressure, it is still easy for hydraulic oil to leak from the gap between the flanges, resulting in a decrease in the hydraulic oil pressure and posing a safety hazard to the connection of the flange at the end of the hydraulic pipeline. Therefore, the practicality of the two-way flange of the hydraulic pipeline is relatively poor.
