Description
Technical field
The utility model relates to distributor, and especially a kind of hydraulic press main allocated equipment, belongs to metal forming machinery field.
Background technology
Hydraulic press take water as the hydraulic press of working media, in mechanical engineering, be mainly used in Forging Technology.Distributor is the key equipment in operating system of water press, by controlling the turnover of water under high pressure, controls hydraulic press moved cross beam, the various stroke using workbench and speed.Distributor is different with role according to position, is divided into main allocated equipment, mobile assignment device etc., wherein main allocated equipment allotment hydraulic press water under high pressure workflow to, it is maximum in each distributor that each parts of main allocated equipment bear pressure.
Main allocated equipment is made up of valve seat, main valve, pressure-relief valve, guide rod, regulating sleeve, spring, seal receptacle etc., regulating sleeve is run through on guide rod top, be provided with the spring around guide rod in regulating sleeve, by the compression of spring, loosen, drive the open and close of pressure-relief valve and the main valve be connected with guide rod bottom.Regulating sleeve screws in seal receptacle, and seal receptacle is arranged on valve seat, and there is the passage that hoists of main valve and pressure-relief valve valve seat inside.As shown in Figure 2, the external diameter of regulating sleeve is generally 65 millimeters to original main allocated equipment regulating sleeve, wall thickness is 5.5 millimeters; Adopt split production, the weld seam that welding process produces is stress tender spots.Operationally, because spring is repeatedly compressed, loosens, regulating sleeve top continues to be subject to spring-force driven dual, and the commissure of regulating sleeve top and spring chamber sidewall easily occurs fatigue damage, causes main allocated equipment top to be ftractureed, and occurs the phenomenon that spring flies in all directions.
Utility model content
The utility model technical issues that need to address are to provide a kind of hydraulic press main allocated equipment, can strengthen the bearing strength of main allocated equipment, prevent main allocated equipment top from ftractureing, eliminate safe hidden trouble.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of hydraulic press main allocated equipment, comprise guide rod, regulating sleeve, seal receptacle, described regulating sleeve is formed in one, and arrange the spring chamber being loaded with spring in regulating sleeve, spring chamber external diameter is 75 millimeters, and wall thickness is 10.5 millimeters, and internal diameter is 54 millimeters; The upper surface of spring chamber and the side angle of cut are circular arc drift angle, and the top of spring chamber is provided with the guide rod hole with its concentric; Regulating sleeve outer wall bottom is provided with the screw thread coordinated with seal receptacle;
Between described spring top and the upper surface of spring chamber and circular arc drift angle place is provided with buffer unit; Regulating sleeve top is also provided with gripping mechanism.
The further improvement of technical solutions of the utility model is: the radius of described spring chamber circular arc drift angle is 5 millimeters.
The further improvement of technical solutions of the utility model is: described buffer unit is rubber sheet gasket or block rubber.
The further improvement of technical solutions of the utility model is: described gripping mechanism comprises cutting ferrule one, cutting ferrule two, cutting ferrule one is closely looped around on guide rod hole outer wall, cutting ferrule two be closely looped around on spring chamber outer wall, be connected by bolt between cutting ferrule one and cutting ferrule two.
Owing to have employed technique scheme, the technological progress that the utility model obtains is:
A kind of hydraulic press main allocated equipment, can strengthen the bearing strength of main allocated equipment, prevent main allocated equipment top from ftractureing, eliminate safe hidden trouble.The regulating sleeve of hydraulic press distributor directly processes with round steel, the top of the regulating sleeve of integral manufacturing and spring chamber sidewall be one inherently, need not again by being welded to connect top and spring chamber sidewall, there is cracking in the junction avoiding regulating sleeve top and spring chamber sidewall; The upper surface of spring chamber and the side angle of cut are circular arc drift angle, the transition of circular arc drift angle connects, and to be moved spring chamber sidewall by regulating sleeve upper bands, the chamber end face of spring intracavity and local, junction, chamber side need to bear instantaneous stress, transition arc drift angle the local stress of having disperseed junction is set, microgroove even ftractures to prevent junction from occurring, enhances the intensity of regulating sleeve; Spring chamber sidewall external diameter is set to 75 millimeters, wall thickness is 10.5 millimeters, internal diameter is 54 millimeters, wall thickness increases, the cross-sectional area of spring chamber sidewall increases, regulating sleeve upper bands move spring chamber sidewall power strengthen cross section on pressure less, add the ability to bear of spring chamber sidewall, the intensity of regulating sleeve.
Between spring top and the upper surface of spring chamber and circular arc drift angle place is provided with buffer unit; Reduce the instantaneous stress that regulating sleeve receives.Regulating sleeve top is also provided with gripping mechanism, gripping mechanism comprises cutting ferrule one, cutting ferrule two, cutting ferrule one is closely looped around on guide rod hole outer wall, cutting ferrule two be closely looped around on spring chamber outer wall, be connected by bolt between cutting ferrule one and cutting ferrule two, the gripping mechanism that main allocated equipment installs additional, further increases the instantaneous stress born of main allocated equipment regulating sleeve, and the bearing strength of main allocated equipment is increased.
