Bottom oil way mechanism of cylinder body of hinge beam of six-face top hydraulic machine

Abstract

The invention discloses a bottom oil way mechanism of a cylinder body of a hinge beam of a six-face top hydraulic machine. The bottom oil way mechanism is an important component in manufacturing of hydraulic machine equipment. The oil way mechanism is optimally designed so that a rear stopper (4) can serve as an independent oil way mechanism to directly supply oil to the interior of a work cylinder (2). Two steps are arranged in the circumferential direction of the rear stopper (4), and the safety of the rear stopper (4) in an ultra-high-pressure environment is improved. A conical stopper (5) with two ends designed to be double-sharp-corner-shaped conical faces is made of a metal pipe material and replaces an oil seal and a rubber ring for sealing, the pressure durability and the pressure resistance of a hydraulic oil pipeline are improved, and equipment faults generated due to blockage of an oil way are reduced. An oil containing groove (8) is additionally formed in the work cylinder direction of the rear stopper (4), so that the problem about suction after a piston (1) moves to a limiting position is solved. The bottom oil way mechanism is novel in design, simple in structure, capable of effectively improving the manufacturing quality of the six-face top hydraulic machine equipment and prolonging the service life of the six-face top hydraulic machine equipment and capable of obviously improving the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of six-sided-top hydraulic press equipment manufacturing, and mainly relates to an oil circuit mechanism at the bottom of a hinge beam cylinder body of a six-sided top hydraulic press. Background technique [0002] The oil circuit mechanism at the bottom of the hinge beam is an important component of the six-sided top hydraulic press. The operation of the press is composed of oil supply through the oil circuit mechanism at the bottom of the hinge beam. The hydraulic oil pushes the piston to move and squeeze the pyrophyllite block to complete the work. The oil circuit mechanism The back plug, three-way valve block and cone plug on the top are important oil circuit components; the working pressure of the hydraulic press is ≥80Mpa. Due to the ultra-high pressure in the working environment, there are strict requirements on the sealing of hydraulic pipe fittings and hydraulic valve parts. The material performance...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the present invention designs an oil circuit mechanism at the bottom of the hinged beam cylinder block of a six-sided top hydraulic press. The design idea of ​​the present invention is: 1. Change the rear blocking structure in the oil circuit mechanism so As an independent oil circuit mechanism, the plug directly supplies oil to the working cylinder. At the same time, two steps are designed in the circumferential direction of the back plug to improve the safety of the back plug in an ultra-high pressure environment and solve the problem of leakage and seepage of the cast hinge beam. 2. Change the seal of the hydraulic oil pipeline in the prior art from an oil seal or a rubber ring seal to a metal pipeline double-pointed cone surface seal, improve the pressure resistance and pressure resistance of the hydraulic oil pipeline, and reduce the risk of Equipment failure caused by blockage of oil circuit and valve parts; 3. Change the length of the cone plug, and correspondingly increase the length and size of the matching hole on the back plug and the three-way valve block and the taper plug, and reduce the matching gap to solve the problem of installation The cone plug is easy to deflect during the process, and the installation and operation are difficult
