Cubic hinge press hinge beam piston component
Technical field
The utility model belongs to diamond synthesis device technical field, relates in particular to the synthetic cubic hinge press hinge beam piston component of a kind of diamond.
Background technology
Cubic hinge press is the synthetic special equipment of diamond, and existing cubic hinge press is to adopt identical six hinge beam assemblies to be formed by connecting by pin hinge.As shown in Figure 1, the press assembly is made up of hinge beam 1, piston 3 and cylinder cap 2 etc., hinge beam and working cylinder one, and piston 3 is positioned at cylinder body, piston rod passes from cylinder cap 2, because the hydraulic oil in the cylinder is very big to the rear portion active force of cylinder, in order to gain in strength, top press each part wall thickness when design is bigger in the course of work, cylinder body is long, ear is subjected to pulling force very big, and thickness is bigger, entire equipment cost height.
The utility model content
The purpose of this utility model provides a kind of stressed little, low cubic hinge press hinge beam piston component of making strength of materials requirement.
The utility model is realized above-mentioned purpose by the following technical solutions: a kind of cubic hinge press hinge beam piston component, the hinge beam is a core structure, tube end central openings, piston is positioned at the hinge beam, piston rod tapping at the bottom of the tube passes, fixed installation plug in opposite end at the bottom of the hinge beam tube, hinge beam and plug are formed cylinder body.
Piston is a hollow barrel formula structure.
The utility model does not have the cylinder cap parts owing to assemble piston and plug outside adopting in hinge beam assembly structure in assemblying, reduce investment outlay; Piston adopts anterior guiding, the rear seal form, and piston is the hollow barrel formula, piston bears very big axial force and passes to the earth by the plug at hinge beam rear portion, and simultaneously, the hinge beam also only is subjected to the effect of hydraulic oil expansive force, relative prior art and saying, pressure reduces greatly, since stressed little, make the strength of materials and require low, top press originally must be the high superior alloy steel of intensity, and the utility model adopt common iron just can, so design is light and handy, the saving material.

The specific embodiment
As shown in Figure 2, a kind of cubic hinge press hinge beam piston component, hinge beam 5 is a core structure, the tube ends 4 center drilling, piston 8 is positioned at hinge beam 5, and piston rod 4 tappings at the bottom of the tube pass, fixed installation plug 6 in 4 opposite ends at the bottom of the hinge beam tube, plug 6 centers are provided with oilhole 9, and piston 8 is a hollow barrel formula structure, and chain ear 7 axially is symmetrically fixed on the outer wall of hinge beam 5.
