Description

Hinge beam structure of cubic apparatus press

Technical Field

The invention belongs to the technical field of manufacturing of cubic presses, and particularly relates to a hinge beam structure of a cubic press.

Background

At present, most of synthetic equipment for superhard materials such as synthetic diamond in China is a cubic hydraulic press, as shown in figures 1 to 3, the first 6X 6MN hinge type' cubic hydraulic press special for synthetic diamond in China is designed and developed in 1964, and the foundation is laid for industrial production of the superhard materials in China. However, the development of technical equipment in the abrasive grinding tool industry lags behind other industries for a long time, the structure of the hinge beam 1 of the key part of the cubic press is basically not changed for more than 50 years, the hinge beam 1 manufactured by the casting process or the forging process adopts a structure of 10 hinge lugs of 2 × 2 and 3 × 2 on the periphery of the cylinder body 12, namely, ten hinge lugs of four hinge lugs 11 and six hinge lugs 13 in total, the whole structure is complex, the difficulty is brought to ensuring and improving the processing precision, the hinge beam is integrally assembled on the base 3 during assembly, and two adjacent hinge beams 1 are hinged with each other.

Chinese patent document, No. CN102580619B, discloses a hinge beam of cubic press and its manufacturing method, the hinge beam of cubic press includes a cylinder body and ears, the joint between the outside of the cylinder body and the ears is provided with ridges, the ears are provided with grooves matching with the ridges, and the two are welded. Compared with the prior art, the hinge beam of the cubic press manufactured by the invention has light weight and long service life, and can meet the requirement of synthesizing the cubic press by a large cavity.

At present, the number of the hinge beam lugs is large, and the distance is small. If a casting process is adopted for manufacturing a blank, each hinge lug can be poured, but due to the structural characteristics that the size of the hinge beam is greatly different and the limitation of the casting process, casting defects are easy to form, and in addition, the casting strength is not high enough to forge the beam, so that the service life of the cast hinge beam is short, and the condition of beam interruption occurs occasionally.

If the forging process is adopted to manufacture the blank, the strength of the hinge beam can be improved by more than 2 times, but the existing hinge lug is thin and small in interval due to the limitation of the forging process, and each lug is difficult to forge respectively. The defects of more material to be removed, large material waste and low processing efficiency caused by forging and blank making are overcome. The industrial requirements of manufacturing the high-strength hinge beam by adopting the forging blank-making process and prolonging the service life of the cubic press are greatly limited. Along with the continuous increase of cubic press working cylinder bore, the cutting degree of difficulty of cylinder body four sides hinge auricle increases, and the material is cut the weight and is up to several tons, causes very big waste.

Preferably, the cylinder body, the two single-hinge lugs and the two double-hinge lugs are manufactured by adopting an integral casting process to form integral forming connection.

Preferably, the cylinder body, the two single-hinge lugs and the two double-hinge lugs are machined by integrally forging blanks firstly and then cutting the two single-hinge lugs and the two double-hinge lugs.

The invention has the following beneficial effects: the hinge beam structure of the cubic press which is continuously used for more than 50 years is improved creatively on the whole, and the structure of 10 hinge lugs of 2 multiplied by 2 and 3 multiplied by 2 on the periphery of the existing cylinder body is changed into the structural form of 6 hinges of 1 multiplied by 2 and 2 multiplied by 2; therefore, the number of the hinge lugs is reduced, the design stress strength is equivalent, only the machining allowance is left for a single hinge lug blank, the distance between the double hinge lugs is larger, and the single hinge lug blank can be easily and directly manufactured during forging and blank manufacturing. If a casting blank manufacturing process is adopted, the casting defects can be reduced due to the reduction of the hinge lugs and the optimization of the structural size. The hinge lug has no large cut material, so that the processing amount is reduced, and the material is greatly saved.

On the other hand, as the six hinge beam structures of the cubic press are mutually hinged through the pin shafts, the number of hinge lugs is reduced, the stress sectional area of the lugs is not reduced, the strength and the rigidity of the six hinge beam structures are not influenced, on the premise of fully ensuring the strength, the complex structure of the existing hinge beam is simplified, the processing difficulty is effectively reduced, the material consumption is greatly reduced, the processing efficiency is improved, and efficient green manufacturing is realized.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 4 to 6, a hinge beam structure of a cubic press comprises a cylinder body 24, wherein the cylinder body surface positioned on the outer side is a cylinder body non-connecting surface during assembly, the cylinder body surface positioned on the inner side is a cylinder body connecting surface, two single hinge lugs 22 and two double hinge lugs 23 are arranged on the cylinder body connecting surface, the single hinge lugs 22 and the double hinge lugs 23 are alternately arranged around the circumferential direction, the central connecting line of the two single hinge lugs 22 is perpendicular to the central connecting line of the two double hinge lugs 23, connecting pin shaft holes 21 with corresponding positions are arranged on the single hinge lugs 22 and the double hinge lugs 23, and the size between the two double hinge lugs 23 is matched with the size of the single hinge lugs 22.

The connection relationship among the cylinder body 24, the two single-hinge lugs 22 and the two double-hinge lugs 23 can be integrally formed and connected in a mode of integral casting process manufacturing; the integrally formed connection may also be formed by first integrally forging the blank and then cutting out the two single hinge tabs 22 and the two double hinge tabs 23.

As shown in figure 6, the invention is integrally located on the base 4 during assembly, six hinge beam structures 2 are symmetrically arranged at the top and the bottom respectively, then four hinge beam structures are arranged around the circumference in the middle, and the single hinge lugs 22 of the hinge beam structures 2 are inserted into the double hinge lugs 23 of the adjacent hinge beam structures 2 and connected through the pin shafts 24, so that the integral cubic press main body is assembled.

The hinge beam structure 2 reduces the number of the hinge lugs, has equivalent design stress strength, only leaves processing allowance for the blank of the single hinge lug 22, has larger distance between the double hinge lugs 23, and can ensure that the blank is easy to be directly made during forging and blank making. If a casting blank manufacturing process is adopted, the casting defects can be reduced due to the reduction of the hinge lugs and the optimization of the structural size. The hinge lug has no large cut material, so that the processing amount is reduced, and the material is greatly saved.

On the other hand, because the six hinge beam structures 2 of the cubic press are mutually hinged through the pin shafts 24, the number of the hinge lugs is reduced, the stress sectional area of the lugs is not reduced, and the strength and the rigidity of the lugs are not influenced.

The hinge beam structure of the cubic press which is continuously used for more than 50 years is improved creatively on the whole, and the structure of 10 hinge lugs of 2 multiplied by 2 and 3 multiplied by 2 on the periphery of the existing cylinder body is changed into the structure form of 6 hinges of 1 multiplied by 2 and 2 multiplied by 2.
