Refer to shown in Fig. 5 and Fig. 6, the crossbeam of hydraulic press of the present invention is the convex beam of uniform strength, is different from the structure of the beam of existing any hydraulic press.The horizontal entablature 6 of " protruding " type is exactly contrary with traditional concept with the horizontal sill 1 of " protruding " type, beam is unequal in the upper size of short transverse, the load plane of beam is not all in same plane, but the stress distribution equilibrium of beam is not fully exerted the potential of material; The loading end of horizontal entablature 6 installment work cylinders is protruded downwards, make the loading end of horizontal sill 1 installment work platform protruding upward.What the distance between two horizontal planes of the bossy body of horizontal entablature 6 and horizontal sill 1 had formed framework window vertically opens a grade H, two vertical planes of bossy body have determined that the interior side clearway of the level of framework window is apart from W, and the material between two vertical planes plays a part again upper and lower horizontal column.

" protruding " type beam of uniform strength structure of the horizontal sill 1 of the present invention for raising up, the upper plane of bossy body is for installment work platform, and two convex shoulder planes are used for supporting two vertical pillars beams 2; 4, these two planes are not in same plane.The both sides vertical plane of bossy body is two vertical pillars beams 2; The medial surface of 4 bottoms provides horizontal direction " X " axle positioning datum, and makes bossy body as lower horizontal column, bears bottom level prestressed draw-bar device 72 by two vertical pillars beams 2; The prestressing force effect of the bossy body pretension all-in-one-piece horizontal direction of 4 bottom and horizontal sill 1; In two convex shoulder planes, be designed with two groups of rectangle keyways and be inlaid with positioning key, can be two vertical pillars beams 2; " Y " axle positioning datum of horizontal direction before and after 4 bottom provides; Two convex shoulder planes are two vertical pillars beams 2; 4 bottom provides vertical direction " Z " axle positioning datum, and bears vertical prestressed draw-bar device 71 by two vertical pillars beams 2; 4 with the prestressing force effect of horizontal entablature 6 and horizontal sill 1 pretension all-in-one-piece vertical direction; According to the required ejecting force of different process object, lower piercing force and hydraulic die cushion power, can be under the interior installation of horizontal sill 1 working cylinder.

Horizontal entablature 6 is " protruding " type girder construction of protruding downwards, and the lower plane of bossy body is used for installing Main cylinder, and two planes of falling convex shoulder are used for supporting two vertical pillars beams 2; 4, these two planes are not in same plane.Two vertical planes of bossy body are two vertical pillars beams 2; The medial surface at 4 tops provides left and right horizontal direction " X " axle positioning datum, and makes down bossy body as upper horizontal column, bears the horizontal prestressed draw-bar device 73 in top by two vertical pillars beams 2; The prestressing force effect of the pretension of the falling bossy body all-in-one-piece horizontal direction of 4 tops and horizontal entablature 6; In two planes of falling convex shoulder, be designed with two groups of rectangle keyways and be inlaid with positioning key, can be two vertical pillars beams 2; " Y " axle positioning datum of horizontal direction before and after 4 top provides; Two planes of falling convex shoulder are two vertical pillars beams 2; 4 top provides vertical direction " Z " axle positioning datum, and bears vertical prestressed draw-bar device 71 by two vertical pillars beams 2; 4 with the prestressing force effect of horizontal entablature 6 and horizontal sill 1 pretension all-in-one-piece vertical direction; On the lower plane of bossy body, Main cylinder is installed falling, according to different vertical nominal pressures and technique object, the quantity of cylinder is 1~6, and the arrangement of cylinder can be single 1,2,3, or is double 2,4,6, or is 3 of three rows, 5.

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, use as just column function, 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 invention; 4 are different from the structure of the column of existing any hydraulic press.Two vertical pillars beams 2; 4, be seen as asymmetrical bow-shaped structural from front, 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 by integral to itself and horizontal entablature 6 and horizontal sill 1 pretension, bear the prestressing force effect of vertical direction, and its horizontal force action of moved cross beam counter-force couple under 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, fitted with two vertical planes of horizontal lower and upper cross-member 6 and 1 bossy body as horizontal column respectively by 4 tops of two vertical pillars beams and the medial surface of 4 bottoms, by bottom level prestressed draw-bar device 72 and 73 respectively by integral the boss pretension of the end of vertical pillars beam and bottom and horizontal lower and upper cross-member 6 and 1; 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 when 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 invention, 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, make to produce prefastening force in pull bar total length by pre-load nut, 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 entirety with horizontal direction respectively in the vertical direction, form a two-way full prestressing framework for support of vertical and horizontal.

The bearing capacity requirement of and horizontal direction vertical according to hydraulic press, determine quantity and the distribution of pull bar in vertical prestressed draw-bar device 71, the horizontal prestressed draw-bar device 73 of bottom level prestressed draw-bar device 72 and top, determine the plate thickness under pull-rod nut according to the stress level of each beam.

Prestressing force design press maximum working load power and maximum allowable offset apart from design, adjust and the prestressing force of setting pull bar, pretension coefficient is 1.5, pretightning force is 1.5 times of service load; Horizontal entablature 6 and horizontal sill 1 and two vertical pillars beams 2; The cross sectional dimensions of 4 contact portions is identical, and the distortion of depth of beam direction after by compression be can not ignore, and the size of the compressed member of calculating should comprise horizontal entablature 6, horizontal sill 1 and two vertical pillars beams 2; 4 corresponding height size.

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 present invention has abandoned the traditional design method that adopts single rough bar, is not only the needs for compact structure design, but the superiority of many thin pull bars is much larger than 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 invention, 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.

The concrete structure of guide way is: guide way 51; 52 guiding side has projection, the top bilateral symmetry of projection is provided with two the first spigot surfaces, the bottom bilateral symmetry of projection is provided with two the second spigot surfaces, the extended line of the first spigot surface and the second spigot surface is all by the center of combined bidirectional prestressing force framework for support, two guide waies 51; 52 upper ends are by prestressed draw-bar fixed connection, two guide waies 51; 52 bottom is all fixedly connected by cross key and screw rod and moved cross beam 3;

Two groups of upper level pull rod device 81 comprise high strength pull bar, by 2 guide waies 51; The two ends transverse prestress of 52 upper beam is consolidated into one; By horizontal screw bolt 82 and cross key by 2 guide waies 51; 52 lower vertical guide way and moved cross beam 3 are laterally consolidated into one.

Guide way 51; 52 upper beam guide plate relies on and is loaded on leading without the wear-resisting slide plate in I place, deformed area on horizontal entablature 6, and middle and lower part vertically-guided plate relies on the wear-resisting slide plate guiding in the II place, micro-deformed area being loaded on left and right vertical pillars beam 4 and 2; The extension line of top and bottom spigot surface is all by the center of framework for support, same guide way 51; Angle α in 52 between two the first spigot surfaces is 60 °-100 °, simultaneously same guide way 51; Angle β in 52 between two the second spigot surfaces is 60 °-100 °, same guide way 51; Angle between angle in 52 between two the first spigot surfaces and two the second spigot surfaces is different.Form two " X " type compound direction systems; The length of guide way is 3 times of its stroke, for moved cross beam provides firm, planar guide body rigidity and LCS.

Combinations thereof formula two dimension prestressing framework for support, adopt Computerized three-dimensional finite element analysis software Analysis of Contact Problem method, frame overall structure is optimized to design, the distortion of frame and stress have been obtained accurately to be solved, dope stress state and the deformation tendency thereof of the structure in the course of work, optimize the structure of stress frame, determine its physical dimension under suitable strength and rigidity, material is reasonably distributed, give full play of the potentiality of material therefor.

Theory analysis shows, this rack construction has higher integral rigidity, fatigue resistance, bearing capacity and security reliability.After frame pretightening, do not crack, without repeating fastening outboard nut, pull bar is forever without wearing and tearing.When work, column bears compression and bending stress, and pull bar bears tension, and the variation amplitude of its minimum and maximum tension is only 15% of maximum load stress.Within the machine life cycle, can not produce column fracture accident, therefore extend the service life of each member, greatly reduces maintenance of equipment expense and life cycle cost.

5), the existing multi-ram forging hydraulic machine working cylinder number of axle is generally 3-5 axle, its horizontal operation cylinder is single shaft, and ability is on the low side, the product weight of shaping is little, can only carry out single horizontal parting and be shaped, and has limited the process application scope of multi-ram forging.

Refer to shown in Fig. 9, multidirectional mould Compound Extrusion hydraulic press of the present invention, is different from existing any multi-ram forging hydraulic press.The described multidirectional mould Compound Extrusion working cylinder number of axle is 7 axles, two " X " type compound direction framves of combined bidirectional prestressing force framework for support and combined type are as the carrier that the devices such as hydraulic cylinder, workbench, mould are installed, and bear whole service loads, form the body part of a multidirectional mould combined precision extrusion molding hydraulic press.
