Abstract
The invention relates to an extruding machine, in particular to an extruding machine for producing metal materials. Aiming at the prior extruding machine with the limit extrusion force and limit production specifications and most of extruding machines adopting a transmission mode that hydrostatic presses provide extrusion force , the invention provides the extruding machine with a mechanical structure and a stressing theory different from the prior extruding machine. The extruding machine adopts a theory that the self weight g (the weight is an arithmetic product of the mass of an object anda local acceleration of gravity) of a pressing mechanism is actively introduced and utilized as extrusion force; gigantic weight is used for ensuring the normal extrusion of extrusion stock so as to effectively break through the limit extrusion force and limit production specifications of the prior extruding machine; and tension columns and beams of the prior extruding machine are canceled under avertical extrusion condition so that the hydrostatic presses do not directly provide extrusion force any more, and the number of the hydrostatic presses is easily combined to provide heavier weight for extrusion. The manufactured extruding machine can produce metal materials produced by the prior extruding machine, and the related extrusion mechanism can be also applied to a metal forge press.
Description
Technical field
The present invention relates to extruder, particularly produce the extruder that metal material is used.
Background technology
Extruder can be divided into conventional hydraulic extruder and hydrostatic extruder by pressuring method, is divided into machine driving extruder and hydraulic drive extruder by the kind of drive; Wherein the machine driving extruder is divided into reciprocating type crank connecting link extruder and continous way extruder (contain CONFORM, continuous casting-Lian squeeze, rolling-Lian squeeze three kinds of continous way extruders) again; The hydraulic drive extruder comprises pump-accumulator transmission, the direct transmission of pump, three kinds of hydraulic drive extruders of booster transmission again.The common mechanical equivalent of light feature of these extruders is: by extruder frame is fixed on the Equipment Foundations, under the effect of machinery or hydraulic coupling, with the stress of the internal mechanical construction package of extruder as the conduction person of extruding force or finally hold the receptor and reach the whole stressed poised state of extruder, thereby force extrusion billet to be deformed into required form.These stressed assemblies can be extruder frame (containing extruder crossbeam and tension force post etc.); Comprise that also assemblies such as recipient, mould are all bearing because the stress that blank or extrusion axis conduction are come.That is to say, guarantee the stressed mechanism of action of extruding of the whole extruder mechanism (not containing Equipment Foundations) of extruding function operate as normal, irrelevant substantially with the gravity that this mechanism is suffered.That is to say that this extruder also can ordinary production in the situation of gravitate not, the gravity of whole extruder mechanism self is not the necessary condition that extrusion process is normally carried out.
At present, the extruding force of extruder can reach 200MN～250MN fully, and the imagination of design 350MN～600MN extruder is arranged.Because have only large-size extruder could produce bigger width, more heavy in section light metal muscle wallboard (also placing hope on the appearance of other new technologies certainly) is arranged, this is the development of technology such as human space flight and aviation, space station, shipbuilding, rolling stock, motorbus, magnetic suspension train, urban light rail vehicle, to the inevitable requirement that light body engineering material proposes, be the human wisdom selection of seeking more speed with low energy consumption of pursuing.
But the volume that increases existing type extruder simply might not be produced more heavy in section extruded product by the successful extruder that makes, because after the extruding force of conventional extruder reaches more than the 200MN, its desired hydraulic press must have high performance, its needed frame must have high load-bearing capacity, such frame, its column, front-axle beam, back rest load are all near the limit of manufacture difficulty.
Summary of the invention
The objective of the invention is to propose a kind of different with the machine construction principle of existing extruder extruder, use the extruder of manufacturing of the present invention can produce the existing fertile metal material of extruder with the stressed principle of extruding; Also can produce the metal material that existing extruder can not be produced, promptly effectively break through existing extruder fertile extruded product limit specification of institute and limit extrusion force, thereby produce the extruded product of wideer cross section specification.The pressing mechanism of Chu Xianing is convenient in order to explain explanation in this manual, unless indicate material character, all uses ferrous materials (extrusion billet can be various metal materials), but also can be other material that substitutability is arranged.The extrusion process that relates in this explanation, the term of extrusion equipment are as the criterion with " metal extrusion press " (metallurgical industry publishing house).
Extruder involved in the present invention still as existing extruder, has fundamentals such as recipient, extrusion axis, mould, die holder.
But different with existing extruder is, extruder involved in the present invention, and the source of its extruding force and gravity have greatest relation, can be described as a kind of with the source of pressing mechanism self gravitation as the power of carrying out normal extrusion.The rack construction of this extruder such as accompanying drawing 1, shown in Figure 2.We can see that the gravity g of weight G is the source (quality that g equals weight multiply by local acceleration of gravity) of extruding force from figure, and the action direction of gravity g is exactly the direction of extruding force.Liftable support column 4 is supported on rigid support face 5 tops, is to stablize and regulate extrusion axis 3 for the whole machine balancing that keeps frame to move up and down, and this requirement is depended in its concrete installation site.Suitably regulate the height of this support column in when extruding, whole gravity g of weight G can press upper holder block 1, and drive extrusion axis 3 and move downward, thereby set up stable extrusion process.
In order to express easily, the bottom of weight G and the rectangle part that extrusion axis directly contacts are referred to as upper holder block 1, and upper holder block 1 is the part of weight G.Support the mechanism of extrusion die, be referred to as lower lock block 2 among the present invention, for explaining conveniently, and it is motionless to think that lower lock block 2 is fixed on the rigid body position, and this rigid body can suppose it is the object of the huge earth character of the earth or other quality.Just formed the position relation and the stressed relation of upper holder block 1 → extrusion axis 3 → recipient and mould 6 → extrusion billet and extruded product 7 → lower lock block 2 so from top to down, what wherein balance each other with gravity g is that lower lock block is to the power of accepting of mould and recipient and the support force of support column 4.
In sum, the gravity g of weight G is essential condition or the necessary condition that gravity-type extruder extrusion process is normally carried out.
The outstanding advantage of this gravity pressure mo(u)ld bottom half extruder is the frame (containing tension force post and crossbeam) that no longer needs the traditional vertical extruder huge, and because huge extruding force is that weight G provides, the hydraulic press that weight is risen and falls do not need to do resemble the conventional extruder huge.Because a plurality of hydraulic presses rise weight and fall, obviously directly apply extruding force and come easily than one, two hydraulic cylinder.The cube of 10 * a 10 * 10m is ferrous materials fully, and its quality will be 7800 tons so; The cube of 12 * a 12 * 12m is ferrous materials fully, and its quality will be 13478 tons so; 20 * 20 * 20m cube is ferrous materials fully, and quality will be 62400 tons so, and with its core component weight G as extruder involved in the present invention, its extruding force is 620MN to the maximum, needs 7～8 100MN hydraulic presses to control lifting.
If change the mutual alignment relation of recipient, extrusion axis, mould certainly, extruder so involved in the present invention obviously can carry out extrusion processes such as forward extrusion, oppositely extruding, quiet liquid extruding; If blank directly is placed between the upper and lower briquetting, as accompanying drawing 5, shown in Figure 6, extruder so involved in the present invention will become the forging press that utilizes gravity to forge and press, but not old-fashioned free-falling hammer forging press, because here it is being controlled upper and lower motion by hydraulic mechanism.But it is different again directly to promote the forging press that forging hammer forges with present ubiquitous hydraulic press, because this machine is directly to utilize gravity g to carry out the metal material forging and pressing.
In fact also can with extruder involved in the present invention by vertical become horizontal, as accompanying drawing 3, Fig. 4, shown in Figure 7.Here need the horizontal framework front end and the pressure transfer of whole extruder are integrated, mechanical stress when its horizontal framework of such extruder still will bear extruding, the extruder of Zhi Zaoing remains the extruder that the present invention relates to like this, remain feasible, but simple not as vertical.
No matter be vertical or horizontal extruder, in the present invention, recipient, extrusion axis, mould, blank will constitute the space of sealing and just can push, particularly horizontal extruder also must pressure transfer 8, press matchmaker 11 and transmit the spaces that the axle 12 of gravity constitutes sealing downwards and just can push.
