Booster-and-framework-integrated cold isostatic press without ultrahigh-pressure pipelines

Abstract

The invention relates to a booster-and-framework-integrated cold isostatic press without ultrahigh-pressure pipelines, which comprises an ultrahigh-pressure cylinder and a piston booster. The cold isostatic press is characterized in that the booster fixedly clings to a semicircular beam of a framework through a fixing frame to form a whole; the ultrahigh-pressure cylinder of the booster is connected with a lateral oil passage orifice of the semicircular beam through a pin with an oil hole; an oil passage of the semicircular beam is communicated with an oil passage of a connecting block; the oil passage of the connecting block is communicated with a vertical oil passage at the bottom of the cylinder; and the vertical oil passage is communicated with an ultrahigh-pressure vessel. By fixedly connecting the ultrahigh-pressure booster and the semicircular beam into a whole and omitting ultrahigh-pressure pipelines, the booster can have a larger overall dimension and a higher efficiency; and the horizontal passage at the bottom of the cylinder is eliminated, thereby ensuring better stressing and higher safety. In addition, the booster has no axial connection structures, so that the ultrahigh-pressure cylinder is hardly subjected to axial force, and the pin connected with the semicircular beam can not be shorn to cause an accident.

Description

technical field [0001] The invention belongs to a cold isostatic press, in particular to a cold isostatic press without an ultra-high pressure pipeline in which a supercharger and a frame are integrated. Background technique [0002] The working pressure of the cold isostatic press is very high, and some even reach 600Mpa, so the ultra-high pressure oil supply generated by the supercharger must pass through a complicated pipeline system, which is not only costly, but also very unsafe. The applicant (ZL 2004 20028968.7) discloses a cold isostatic press with an integral reciprocating supercharger without an ultra-high pressure pipeline. The side of the lower end cover of the main cylinder of the cold isostatic press is in contact with the reciprocating The two ultra-high pressure oil cylinders of the press are respectively connected to the two ends of the lower end cover of the main cylinder of the cold isostatic press through the left key pin and right key pin embedded in the...

AI Technical Summary

Problems solved by technology

When the supercharger is loosened to the connection, the left key pin and the right key pin will be subject to a large axial shear stress, which will be damaged and cause an accident

In addition, the supercharger is connected to the bottom of the cylinder, and it is inconvenient to lift and lower, which is not conducive to frequent cleaning of the bottom of the cylinder, and it is inconvenient to maintain.
