" convex " type beam of uniform strength structure of the horizontal sill of the present invention 1 for raising up, the upper plane of bossy body is used for erector's station, and two convex shoulder planes are 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; Medial surface bottom 4 provides " X " axle positioning datum of horizontal direction, 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 bottom of 4 and the bossy body pretension all-in-one-piece horizontal direction of horizontal sill 1; 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; The bottom of 4 provides " Y " axle positioning datum in anterior-posterior horizontal direction; Two convex shoulder planes are two vertical pillars beams 2; The bottom of 4 provides " Z " axle positioning datum of vertical direction, 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; Ejecting force needed for different process object, lower piercing force and hydraulic die cushion power, working cylinder under can installing in horizontal sill 1.
Horizontal entablature 6 is " convex " type girder construction protruded downwards, and the lower plane of bossy body is for installing Main cylinder, and two planes of falling convex shoulder are 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 " X " axle positioning datum in left and right horizontal direction, 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; 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; The top of 4 provides " Y " axle positioning datum in anterior-posterior horizontal direction; Two planes of falling convex shoulder are two vertical pillars beams 2; The top of 4 provides " Z " axle positioning datum of vertical direction, 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; Fall bossy body lower plane on Main cylinder is installed, 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 be three row 3,5.
2), the column of existing hydraulic press is mostly independently 4 solid or hollow circles or rectangular configuration, or is multi-laminate plank frame, 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), the service load of horizontal direction or transverse direction can not be born.The integral multi-layered stacked plate type had or integral slab frame hydraulic press, although allow the working cylinder at the horizontal direction mounting flange supporting type of column part, but due to the restriction by this type structure, the service load of the horizontal direction that 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 structures being different from the column of existing any one hydraulic press.Two vertical pillars beams 2; 4, being seen as asymmetrical bow-shaped structural from front, is 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 be plane inside it, outside has protuberance.The cross-sectional area of the part that the beam of uniform strength is positioned at above protuberance from up to down increases gradually, and the cross-sectional area of the part that the beam of uniform strength is positioned at below protuberance 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 and 4 tops of 4 are bearing between two convex shoulder planes of horizontal sill 1 and two convex shoulder planes of horizontal entablature 6, by vertical prestressed draw-bar device 71 by itself and horizontal entablature 6 and horizontal sill 1 pretension integral, bear the prestressing force effect of vertical direction, and angle moment of flexure under service load, its horizontal force action of moved cross beam counter-force couple under eccentric load; Two vertical pillars beams 2; The bottom of 4 and top level 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 as " Y " axle positioning datum of upper and lower horizontal gird 6 and 1 in anterior-posterior horizontal direction.
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 bottom level prestressed draw-bar device 72 and 73 respectively by integral for the boss pretension of the end of vertical pillars beam and bottom and horizontal lower and upper cross-member 6 and 1 by 4 tops of two vertical pillars beams and the medial surface of 4 bottoms; Middle part between the vertical pillars beam of every side, by circular or rectangular cylinder 21 transverse splicing, in order to install with the horizontal operation cylinder of cylinder bottom support, and allows the service load bearing larger horizontal direction; According to different horizontal nominal pressures and technique object, the quantity of cylinder can be a single acting hydraulic cylinder, or a compound pair of hydrodynamic cylinder pressure, or the hydraulic cylinder that two rows are above.
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, and bear unidirectional amplitude alternate stress during work, fatigue resistance is low.Although some hydraulic presses have employed 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, constitutes multi-ram forging hydraulic press, but can not close due to its power system, causes frame and mould again and again to damage.And being subject to the restriction of this type structure, the service load of the horizontal direction that can bear is 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 one 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 pretightning force and the pre-tension method of design code, make pull bar total length produces prefastening force by pre-load nut, simultaneously to horizontal entablature 6, horizontal sill 1 and two vertical pillars beams 2; 4 apply preload pressures, thus 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, according to the plate thickness under the stress level determination pull-rod nut of each beam.
Pre-stress design presses maximum working load power and the maximum allowable offset prestressing force apart from design, adjustment and setting pull bar, and pretension coefficient is 1.5, and namely 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, depth of beam direction by compression after distortion can not ignore, calculating should be comprised horizontal entablature 6, horizontal sill 1 and two vertical pillars beams 2 by the size of compression element; The corresponding height size of 4.
No matter whole frame is that vertical direction or the stressed of horizontal direction are internal force balance system, and load force can not be delivered on basis, ensure that the safety and reliability of the two-way carrying of frame.
The present invention has abandoned the traditional design method of the single rough bar of employing, be not only the needs for compact structure design, but the superiority of many thin pull bars is much larger than only using a rough bar: available less hydraulic pre-tightening cylinder, respectively the every root pull bar of pretension; By hollow column cross sectional shape, Duola's bar can be arranged symmetrically and evenly, 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 uniformity good, the mechanical property of material can be given full play to; Processing and manufacturing and easy for installation.
4), blade fin face that the operation of conventional hydraulic machine moved cross beam all relies on column to provide leads, and so-called " X " spigot surface is in the same plane of identical angle, and moved cross beam guiding length is similar to its stroke.Under service load, due to the lateral bending deformation of column, be easy to guiding length is originally deflected with regard to very short moved cross beam, guiding accuracy can not be guaranteed.
Refer to shown in Fig. 7 and 8, two " X " type compound direction system of combined type of the present invention, is different from the guidance mode of existing any one hydraulic press, comprises the identical and guide way 51 of front and back symmetry of two size structures; 52.
The concrete structure of guide way is: guide way 51; The guiding side of 52 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 all by the center of combined bidirectional prestressing force framework for support, two guide waies 51; Prestressed draw-bar fixed connection is passed through in 52 upper ends, two guide waies 51; The bottom of 52 all by cross key and screw rod and moved cross beam 3 fixedly connected;
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; The lower vertical guide way of 52 and moved cross beam 3 are laterally consolidated into one.
Guide way 51; The upper beam guide plate of 52 relies on and is loaded on leading without the wear-resisting slide plate in deformed area I place on horizontal entablature 6, and middle and lower part vertically-guided plate relies on the wear-resisting slide plate guiding in the place of Light deformation district II be loaded on left and right vertical pillars beam 4 and 2; The extension line of top and bottom spigot surface 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 in 52 between two the first spigot surfaces is different from the angle between two the second spigot surfaces.Form two " X " type compound direction system; The length of guide way is 3 times of its stroke, that provide firm a, rigidity for moved cross beam with planar guide body that is LCS.
Combinations thereof formula two dimension prestressing framework for support, adopt Computerized three-dimensional finite element analysis software Analysis of Contact Problem method, design is optimized to frame overall structure, the distortion of frame and stress are obtained solve accurately, 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, gives 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 the need to repeating fastening outboard nut, pull bar is forever without wearing and tearing.During work, column bears compression and bending stress, and pull bar bears tension, and the change amplitude of its minimum and maximum tension is only 15% of maximum load stress.Can not produce column fracture accident within the machine life cycle, therefore the service life of each component extend, and 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, and its horizontal operation cylinder is single shaft, and ability is on the low side, and the product weight of shaping is little, can only carry out single horizontal parting and be shaped, limit 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 one multi-ram forging hydraulic press.The described multidirectional mould Compound Extrusion working cylinder number of axle is 7 axles, combined bidirectional prestressing force framework for support and two " X " type compound direction frame of combined type are as the carrier installing the devices such as hydraulic cylinder, workbench, mould, and bear whole service load, namely form the body part of a multidirectional mould combined precision extrusion molding hydraulic press.
