Description

Hinge beam of hexahedral top hydraulic press

Technical Field

The utility model relates to the technical field of synthetic hydraulic presses for artificial diamonds, in particular to a hinge beam of a hexahedral top hydraulic press.

Background

In the field of synthetic diamond, a hexahedral hydraulic press is a machine for generating high pressure in synthetic diamond, the hexahedral hydraulic press is assembled by 6 hinge beams with the same structure and size through pin shafts, in the working process, a hydraulic cylinder is gradually pressurized through oil holes, the maximum pressure can reach 110Mpa, each ear of the hinge beams and the pin shafts bear great interaction force, in actual production, damage such as cracking and fracture (obtained through stress analysis of the whole machine) is found to occur to 2 ears, because the pin shafts are made of non-rigid materials, elastic deformation and plastic deformation phenomena exist in the interaction of the pin shafts and the pin shaft holes, and then the stress of 3 ears 2 is greatly reduced compared with the stress under the condition that the pin shafts are assumed to be rigid, and the 3 ears bear main acting force, so that the failure is frequent, the space of the hinge beams is limited, and the problems can not be solved by a method of simply increasing the thickness of each ear.

Disclosure of Invention

The utility model aims to provide a hinge beam of a hexahedral hydraulic press, which solves the problems in the prior art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the hinge beam of the hexahedral top hydraulic press comprises hinge beam bodies, wherein connecting lugs are arranged on the hinge beam bodies, pin shafts are arranged between the hinge beam bodies, and the adjacent hinge beam bodies are connected through the pin shafts; the connecting lugs comprise ears and single ears.

Optionally, bolts are connected to two ends of the pin shaft in a threaded manner, and through holes are formed in the bolts.

Optionally, the thickness of the single ear is 28-30cm.

Optionally, the thickness of the ears is 15-17cm.

Optionally, the distance between the ears is 30-33cm.

Compared with the prior art, the utility model has the beneficial effects that:

1. according to the utility model, the connecting lugs are changed into the single lug and the double lugs, the traditional double lugs and the traditional triple lugs are thinner in the fixed connecting area, the pressure required to be born by the single lug is overlarge, the thickness of the single lug and the double lugs is increased, the pressure required to be born is larger, the space required to be compared with the difference between the double lugs and the triple lugs is not large, and the use is not influenced.

2. According to the utility model, liquid nitrogen is injected into the through hole, and the liquid nitrogen is gasified and discharged from the through hole at the other end, so that the diameter of the pin shaft is reduced due to the effect of thermal expansion and cold contraction, and the assembly difficulty of the pin shaft and the pin shaft hole is reduced.

Detailed Description

In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description will refer to the specific implementation, structure, characteristics and effects according to the present utility model with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1 to 3, a hinge beam of a hexahedral top hydraulic press comprises hinge beam bodies 1, wherein connecting lugs 2 are arranged on the hinge beam bodies 1, pin shafts 3 are arranged between the hinge beam bodies 1, and the adjacent hinge beam bodies 1 are connected through the pin shafts 3; the connecting ear 2 includes a binaural 21 and a monaural 22.

Through changing connector lug 2 into monaural 22 and ears 21, in fixed connection region, traditional ears 21 and three ears, the thickness of ear is thinner, and the pressure that single ear needs to bear is too big, and the thickness of monaural 22 and ears 22 increases, can bear the pressure more, and the space contrast that needs is little in ears 21 and three ears difference moreover, can not influence the use.

The two ends of the pin shaft 3 are connected with bolts 4 in a threaded manner, and through holes 5 are formed in the bolts 4;

when the pin shaft 3 is installed or disassembled, liquid nitrogen is injected into the through hole 5, and the liquid nitrogen is gasified and discharged from the through hole 5 at the other end, so that the diameter of the pin shaft 3 is reduced due to the expansion and contraction effect, and the assembly difficulty of the pin shaft 3 and the pin shaft hole is reduced.

Specifically, the thickness of the single ear 22 is 28-30cm

Specifically, the thickness of binaural 21 is 15-17cm.

Specifically, the distance between the ears 21 is 30-33cm.

The present utility model is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present utility model.
