2), the column of existing hydraulic press is mostly independently 4 solid or hollow circles or rectangular configuration, or is multilayer stacked plate type structure, or is frame-type box structure.Their common trait is, as just column function, use, be supported between lower and upper cross-member (for vertical hydraulic press) or front and back crossbeam (for horizontal hydraulic machine), bear compression (for prestressed structure) or tension (for non-prestressed structure), can not bear horizontal direction or horizontal service load.The integral multi-layered stacked plate type having or integral slab frame hydraulic press, although allow the working cylinder at the horizontal direction mounting flange supporting type of column part, but owing to being subject to the restriction of this type structure, the service load of the horizontal direction can bear is only 1/5 of vertical direction.
Refer to shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4 the vertical pillars beam 2 of special tectonic of the present utility model; 4 are different from the structure of the column of existing any hydraulic press.Two vertical pillars beams 2; 4, from front, be seen as asymmetrical bow-shaped structural, be asymmetrical " H " type structure from the side.Concrete, vertical pillars beam 2; 4 comprise two beam of uniform strengths and sleeve, and two beam of uniform strengths are by sleeve transverse splicing, and the cross section of the beam of uniform strength is rectangle, and its inner side is plane, and outside has protuberance.The cross-sectional area that the beam of uniform strength is positioned at the part of protuberance top from up to down increases gradually, and the cross-sectional area that the beam of uniform strength is positioned at the part of protuberance below from up to down reduces gradually, and sleeve and axis thereof are in horizontal direction between two beam of uniform strengths.As vertical pillars function, it is the hollow rectangular cross section in middle part on overall height; By two vertical pillars beams 2; 4 bottoms of 4 and 4 tops are bearing between two convex shoulder planes and two convex shoulder planes of horizontal entablature 6 of horizontal sill 1, by vertical prestressed draw-bar device 71, itself and horizontal entablature 6 and horizontal sill 1 pretension are integral, bear the prestressing force effect of vertical direction, and its horizontal force action of moved cross beam counter-force couple under the angle moment of flexure under service load, eccentric load; Two vertical pillars beams 2; On 4 bottom and top horizontal plane, be all designed with two groups of rectangle keyways and be inlaid with positioning key, by horizontal entablature 6 and horizontal sill 1 and vertical pillars beam 2; 4 are embedded in together securely, and the upper and lower horizontal gird 6 and 1 of conduct is at " Y " of front and back horizontal direction axle positioning datum.
As vertical beam function, two vertical pillars beams 2; 4 is hollow variable cross-section bow beam structure, by 4 tops of two vertical pillars beams and the medial surface of 4 bottoms, fitted with horizontal lower and upper cross-member 6 as horizontal column and two vertical planes of 1 bossy body respectively, by bottom level prestressed draw-bar device 72 and 73, respectively the boss pretension of the end of vertical pillars beam and bottom and horizontal lower and upper cross-member 6 and 1 is integral; Middle part between each side vertical pillars beam, by circle or rectangle cylindrical shell 21 transverse splicings, in order to the horizontal operation cylinder with cylinder bottom support to be installed, and allows to bear the service load of larger horizontal direction; According to different horizontal nominal pressures and technique object, the quantity of cylinder can be a single action hydraulic cylinder, or a compound pair of hydrodynamic cylinder pressure, or the above hydraulic cylinder of two rows.
3), the hydraulic press of conventional tension cylindricality formula, integral multi-layered stacked plate type or integral slab frame hydraulic press, their common trait is, frame is non-prestressed structure, bears unidirectional amplitude alternate stress during work, fatigue resistance is low.Although some hydraulic presses have adopted prestressed structure, mostly be the vertical hydraulic press of independent vertical direction, or the one direction prestressed structure of the horizontal hydraulic machine of horizontal direction; What have combines a vertical prestressed stand and a horizontal prestressed stand, has formed multi-ram forging hydraulic press, but because its power system can not seal, causes frame and mould again and again to damage.And to be subject to the restriction of this type structure, the service load of the horizontal direction can bear be only 1/3 of vertical direction.
Refer to shown in Fig. 1 and Fig. 2, the two-way full prestressing system of vertical and horizontal of the present utility model, is different from the prestressing force mode of existing any hydraulic press.The two-way full prestressing system of vertical and horizontal, in vertical prestressed draw-bar device 71, the horizontal prestressed draw-bar device 73 of bottom level prestressed draw-bar device 72 and top, pull bar diameter is all between 160～280mm, according to the pretightning force of design code and pre-tension method, by pre-load nut, make to produce prefastening force in pull bar total length, simultaneously to horizontal entablature 6, horizontal sill 1 and two vertical pillars beams 2; 4 apply preload pressure, thereby by horizontal entablature 6 and horizontal sill 1 and two vertical pillars beams 2; 4 are closely consolidated into an integral body with horizontal direction respectively in the vertical direction, form a two-way full prestressing framework for support of vertical and horizontal.

No matter whole frame is the stressed internal force balance system that is of vertical direction or horizontal direction, and it is upper that load force can not be delivered to basis, has guaranteed the safety and reliability of the two-way carrying of frame.
The utility model has been abandoned the traditional design method that adopts single rough bar, be not only the needs for compact structure design, but the superiority of many thin pull bars is much larger than in only with a rough bar: available less hydraulic pre-tightening cylinder, distinguish every pull bar of pretension; Can, by hollow column cross sectional shape, arrange symmetrically and evenly Duola's bar, stress equalization; Pull rod screw root mismachining tolerance is little, and the bending stress impact of generation is less; Because cross-sectional area is little, material structure and heat treatment performance good uniformity, can give full play to the mechanical property of material; Processing and manufacturing and easy for installation.
4), the operation of conventional hydraulic machine moved cross beam all relies on the blade fin face that column provides to lead, in the same plane of so-called " X " spigot surface in identical angle, and moved cross beam guiding length is similar to its stroke.Under service load, due to the transverse curvature distortion of column, the length that is easy to make originally lead deflects with regard to very short moved cross beam, and guiding accuracy can not be guaranteed.
Refer to shown in Fig. 7 and 8, two " X " type compound direction systems of combined type of the present utility model, are different from the guidance mode of existing any hydraulic press, comprise two guide waies that size structure is identical and front and back are symmetrical 51; 52.
