Abstract

Disclosed is a hinge beam for a hinged cubic hydraulic press. A lug portion of the hinge beam is formed by combining a thick tab with a thin tab. The hinge beam is characterized in that concave surfaces are arranged on two lateral faces of the thick tab, and concave surfaces are arranged on the inner lateral faces of the thin tab. The tabs are designed more reasonably, effective through quenching for heat treatment can be achieved, tab processing amount and part assembly difficulty are decreased, the weight of a workpiece is reduced, and product cost is reduced.

Description

A kind of hinge type cubic hydraulic press hinge beam

Technical field

The utility model relates to a kind of hinge beam of hinge type cubic hydraulic press.

Background technology

The hinge type cubic hydraulic press is mainly used in the extra-high tension unit of synthesis of artificial diamond, and six oil cylinders of its main frame are contained in respectively in six cross hinge beams, through pin the hinge beam are hinged into a space body; Piston in the oil cylinder simultaneously to the center pressurization, forms the square pressure cavity of six pressurizeds by electrical equipment and HYDRAULIC CONTROL SYSTEM, in work on hand oil cylinder and the press that the hinge beam formula of revealing all the details connects in the hinge type cubic hydraulic press; Hinged between its hinge beam is that the auricle cross-articulation of the varying number that caused by two kinds of variable thickness forms; Promptly be three auricles and two auricles or four auricles and three cross-articulation such as auricle, requirement on machining accuracy is very high between the auricle, but existing thick auricle is big and thick; With φ 650mm cylinder diameter press is example; Its thick auricle thickness is about 150 mm, causes effectively through hardening of heat treatment, and material can not fully effectively utilize; The safety coefficient of equipment reduces, and descend to service life; And the assembly difficulty of this thick auricle is also high, the workpiece Heavy Weight, and cost is high.

The utility model content

The purpose of the utility model is to overcome the shortcoming of prior art, and another kind of hinge beam is provided, and can satisfy the effective through hardening of heat treatment, so that the design of hinge type cubic hydraulic press is more reasonable; Support, protection to hinge beam bottom are stronger, reduce auricle processing capacity and part assembly difficulty; Alleviate workpiece weight simultaneously, reduce product cost, make the hinge type cubic hydraulic press that more large-tonnage and high accuracy arranged, build good easily more economically platform for the process exploitation of the big cavity of superhard material.

The technical scheme of the utility model is: the ear of hinge beam part is combined by thick auricle and thin auricle, is equipped with concave surface on the two sides of said thick auricle, thin auricle medial surface be provided with concave surface.

Concave surface place thickness on the two sides of said thick auricle be same model do not have the thick auricle thickness of concave surface 60%～95%.

The concave surface place thickness of the medial surface of said thin auricle be same model do not have the thin auricle thickness of concave surface 60%～95%.

The advantage of the utility model: the thickness of (1) single auricle reduces, effectively through hardening during heat treatment, and it is higher to make the strength ratio of same model specification hinge beam not have concave surface auricle ear; Make the hinge type cubic hydraulic press that more large-tonnage and high accuracy arranged; (2) weight of the hinge beam of its equality strength, comparable size is lighter, has reduced product cost; (3) reduce the auricle processing capacity, reduced the difficulty of assembling; (4) built more economically for the process exploitation of the big cavity of superhard material, good platform easily.

Description of drawings

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is described further.

Embodiment: referring to Fig. 1 front view, Fig. 2 vertical view:

Present embodiment is a φ 650mm cylinder diameter hinge type cubic hydraulic press hinge beam

Referring to accompanying drawing:

Hinge beam 1 is combined with thin auricle 3 by thick auricle 2.

Be provided with concave surface 2-1,2-2 in the two sides of thick auricle 2, concave surface 3-1 arranged at the medial surface that approaches auricle 3;

The shape of side concave surface 2-1,2-2 and 3-1 is consistent.

Thickness is 118mm at the side concave surface place of thick auricle 2; Be same model do not have the thick auricle thickness of concave surface 150mm about 78.5%.

The concave surface place thickness of the medial surface of thin auricle is 71mm; Be same model do not have the thin auricle thickness 83mm of concave surface about 85.5%.
