Description
Technical field
The utility model relates to the stress metal forming field, especially a kind of driven roller supporting and adjusting device of overlarge type ring rolling machine of machining large cylinder forgings.
Background technology
Along with the fast development of key areas technical equipments such as China's nuclear reactor, petrochemical industry, wind-power electricity generation, Aero-Space, the demand of large-scale cartridge type forging is grown with each passing day, simultaneously size, performance and the material of ring are all had higher requirement.But it is high that this large-scale shell ring requires capacity of equipment, and the production difficulty is bigger.
Existing Ring Rolling Machine equipment is the vertical or horizontal single chassis structure that is no matter, promptly embracing roller, driven roller, core roller one end is unsettled by the frame support other end, because the following shortcoming of the above-mentioned Ring Rolling Machine ubiquity of this cantilever structure: poor rigidity, when rolling, the unsettled side distortion of each roller is big, is unfavorable for improving rolling power; Roll axis and transmission shafts are to all not parallel, transmission system all need dispose steering mechanism, steering mechanism has then limited the raising of rolling power, while transmission system complexity, increased the cost on equipment and basis, as the horizontal type structure that roll is vertically arranged, make roll-force be subjected to the restriction of bevel gear modulus to be difficult to improve.Because above-mentioned limitation, to roll over the ring apparatus maximum rolling force at present both at home and abroad and be no more than 600 tons, the ring weight of production, specification are little, highly generally less than 1 meter, only are used for the manufacturing of products such as bearer ring, gear ring, flange, wheel hub.Therefore the production of present large-scale cartridge type forging also has to rely on large-scale hydraulic press to carry out flat-die forging to solve, and this explained hereafter work efficiency is low, poor dimensional precision, and the forging utilization rate is lower, needs heating for multiple times, and energy consumption is big, and the forging manufacturing cost is higher.
For this reason, the applicant has applied for the patent application that application number is 201010186082.5, name is called overlarge type ring rolling machine, this ring rolls frame adopts the open top roll housing of being made up of fore side frame, transmission side frame, cross member, and machine frame at two sides all adopts integrally closed casting, good rigidly; Its core roller, driven roller, an armful roll axis are and are horizontally disposed with, two end supports, driven roller is arranged between fore side frame and the transmission side frame bottom, the core roller is arranged at the driven roller top between transmission side frame and the fore side frame, embraces roller and is arranged at the driven roller both sides; Extract out also to be provided with and take out roller mechanism in order to be inserted in core roller in the ring when the loading and unloading, during loading and unloading, extract the assembling of core roller out by taking out roller mechanism, after the ring lifting, again core roller assembling is sent between the machine frame at two sides, finished being connected of the assembling of core roller and core roller feed mechanism.
This overlarge type ring rolling machine is owing to adopt two-shipper shelf structure, roll horizontally disposed, driven roller, core roller, embraces roller all by two end supports, good rigidly, the rolling power that can bear is big, ring product specification, weight that can be rolling be big, and scope is wide, can adapt to large-scale shell ring and make requirement.Compare with existing hydraulic press open die forging machining large shell ring, the working (machining) efficiency height is rolled over ring time weak point continuously, and the heating number of times is few, and energy savings reduces loss; The machining accuracy height significantly reduces the following process surplus, improves stock utilization, reduces manufacturing cost; Rolling ratio is big, spreading continuously, and the forging distortion evenly can reduce the generation of forge crack and growing up of crystal grain, and the ring performance is good; Compare with forging, impact, vibrations and noise are little.
This ultra-large type radially bottom roll of driven roller assembling arrangement form and the plate mill of Ring Rolling Machine is assembled similar, its mounting structure, roll change mechanism all can adopt the form of the bottom roll assembling of plate mill, but because ring weight is mainly supported by driven roller, therefore the driven roller load-bearing requires to be far longer than the bottom roll of plate mill, the assembling of corresponding driving roller is compared with the assembling of plate mill bottom roll, structure is big, weight is big, therefore the space between driven roller assembling and the frame is narrow and small, the Ring Rolling Machine fore side also needs to reserve installing space and activity space for taking out roller mechanism simultaneously, therefore fore side frame outer space is narrow and small equally, when adopting the bottom roll roll change mechanism that has plate mill now to carry out roll change, operation easier is big.
For this reason, in the above-mentioned application drive roller shaft bearing of driven roller by two ends through adjusting pad by the slide support fixation, fix by spacing between slide and the frame, be provided with the driven roller assembling lifting mechanism that is made of four lifting hydraulic cylinders that are fixed in frame between drive roller shaft bearing and the frame, the lifting Position of Hydraulic Cylinder is corresponding with four jiaos of driven roller assembling bottoms respectively.During roll change, the cardan axis locking of power transmission shaft, coupling propeller shaft is by being fixed in the enclasp device locking positioning of transmission side frame, remove spacing the fixing between slide and the frame, pull out slide then, old driven roller assembling is hung and new driven roller assembling is hung to slide by driving, push slide then, new driven roller assembling is installed.
But because the axis height of new and old driven roller assembling is inconsistent, just need before and after roll change, driven roller be assembled lifting by lifting mechanism, then by the adjusting pad adjustment with the axis Height Adjustment of new and old driven roller assembling to connect axis height consistent location, i.e. roll change absolute altitude position.After finishing new driven roller installation, also need to assemble by lifting mechanism lifting driven roller once more, make driven roller assemble by the adjustment adjusting pad and meet rolling absolute altitude requirement.Because the frame bottom space is narrow and small, and the adjustment of adjusting pad all needs manually to carry out, and is difficult to once adjust to the right place, therefore operate loaded down with trivial details, waste time and energy, poor stability.Can certainly be realized by the upper-lower position adjusting device that setting connects an enclasp device, but the frame bottom space is narrow and small, especially outside the transmission side frame, the drive unit of position regulator can't be arranged near the enclasp device, can't directly drive enclasp device by drive unit, can only link by linkage etc., it is low that therefore difficulty, mechanism's complexity, reliability be set.

Below in conjunction with drawings and Examples the utility model is further specified.
The driven roller supporting and adjusting device of overlarge type ring rolling machine of the present utility model is formed the driven roller assembling by driven roller 31 and two ends drive roller shaft bearing 32 thereof, and described driven roller assembling is arranged between fore side frame 12 and transmission side frame 11 bottoms; The assembling of described driven roller is supported by adjustable for height rolling bracing or strutting arrangement, and axially the fixing to position limiting structure by detachable shaft of driven roller assembling; Be provided with by fore side frame 12 outsides through the track 15 of the framework window of fore side frame 12, framework window that cross member 13 extends to transmission side frame 11 and the slide 4 that is slidingly matched with track 15; Transmission side frame 11 is provided with the enclasp device of coupling propeller shaft 14, described rolling bracing or strutting arrangement is arranged between driven roller assembling and the slide 4 or also supports drive roller assembling between driven roller assembling and the frame, perhaps is arranged between slide 4 and the frame and through slide 4 supports drive roller and assembles; Described slide 4 is provided with the roll change bracing or strutting arrangement of constant height, and the driven roller axis height setting when driven roller assembling supported by the roll change bracing or strutting arrangement is the roll change absolute altitude; Described axle 14 enclasp devices that connect are fixed in transmission side frame 11, and the described level height that connects axle 14 enclasp devices is fixed and corresponding with the roll change absolute altitude; In addition, the driven roller supporting and adjusting device also is provided with the driven roller assembling is switched on rolling bracing or strutting arrangement and roll change bracing or strutting arrangement switching mechanism between the two.
When rolling ring, the driven roller assembling is supported by rolling bracing or strutting arrangement, axially fix by the axial limiting structure, the axial float of driven roller when having avoided rolling, rolling bracing or strutting arrangement adjustable height, after the driven roller wearing and tearing, make the driven roller assembling satisfy the requirement of rolling absolute altitude all the time by the height of adjusting rolling bracing or strutting arrangement, satisfy and roll the ring requirement.During roll change, the driven roller assembling switches to change into by the roll change bracing or strutting arrangement by switching mechanism to be supported, because roll change bracing or strutting arrangement location constant height, spacing between corresponding driving roll bearing seat 32 contact-making surfaces and its bearing axis is also constant, with driven roller axis height setting at this moment is the roll change absolute altitude, the roll change absolute altitude is constant, need not before and after roll change, manually to adjust by adjusting adjusting pad 41, also need not to be provided with the upper-lower position adjusting device of enclasp device, be placed into the driven roller assembling on the roll change bracing or strutting arrangement and dismantling the assembling of axial limiting structure rear-guard action roller and can pull out, the lifting of convenient new and old driven roller assembling with slide 4.When newly rod was installed, new driven roller assembling can slip into slide 4, and driven roller homalocephalus 36 can directly insert and connect axle 14 formation connections.Therefore during the driven roller roll change, can finish the conversion of driven roller absolute altitude easily by the conversion between the two cover bracing or strutting arrangements, easy to operate, roll change efficient height, the roll change process is safe and reliable, and mechanism is simple.
According to the difference of the set-up mode of rolling bracing or strutting arrangement, the set-up mode of axial limiting structure is also different, and when being arranged between driven roller assembling and the frame as rolling bracing or strutting arrangement, the axial limiting structure also is arranged between driven roller assembling and the frame; When rolling bracing or strutting arrangement was arranged between slide 4 and the frame, the axial limiting structure was arranged between driven roller assembling and the frame or between slide 4 and the frame.
When rolling bracing or strutting arrangement be arranged at driven roller assembling or slide 4 with frame between the time, because ring 10 weight are mainly supported by driven roller 31, the weight and the roll-force of ring 10, driven roller assembling all are passed to frame by rolling bracing or strutting arrangement, therefore be the stability that guarantees to support when rolling and the dispersion of bearing capacity, the total volume of rolling bracing or strutting arrangement all need to be provided with enough greatly.Under the narrow and small prerequisite of frame bottom space, in order rolling bracing or strutting arrangement to be arranged at driven roller assembling or slide 4 with between the frame, with regard to the structure that needs change frame bottom or the strong point that a plurality of dispersions are set etc., must cause the complicated of mechanism, to reduce system reliability, and adopt the mode meeting that disperses the strong point because the degree of regulation of influence of rolled absolute altitudes such as the fit clearance of each strong point, synchronism difference.
Therefore, best, described rolling bracing or strutting arrangement is arranged between driven roller assembling and the slide 4, is provided with circumferential position limiting structure between described drive roller shaft bearing 32 and the slide 4.Circumferentially position limiting structure can limit the displacement that driven roller assembles any horizontal direction, therefore can reduce the dynamic load that driven roller displacement, vibration etc. form rolling bracing or strutting arrangement, improve the stability that driven roller supports ring 10, when adjusting absolute altitude, play the effect of guiding simultaneously.At this moment, accordingly, the axial limiting structure can be arranged between slide 4 and the frame, the fixing by circumferential position limiting structure between slide 4 and the drive roller shaft bearing 32 and the common formation of the axial limiting structure between slide 4 and the frame to the driven roller assembling, but in order to reduce matching relationship, enhancing is to the fixed effect of driven roller assembling, strengthen the stability of strutting system of driven roller to ring 10, best, the axial limiting structure directly is arranged between driven roller assembling and the frame, also is between drive roller shaft bearing 32 and the frame.The axial limiting structure can be a structure arbitrarily, and is spacing as step, draw-in groove is spacing, baffle plate is spacing, bolt connection etc., and bolt connects relatively, and step is spacing, draw-in groove is spacing, baffle plate is spacing can control automatically by oil cylinder.
Above-mentioned circumferential position limiting structure can the insertion by boss 43 and groove 44 cooperates, is provided with guiding mechanism such as guide pillar between driven roller assembling and slide or other modes are realized.Concrete, described driven roller assembling is circumferentially spacing fixing by inserting the boss 43 and groove 44 formations that cooperate with slide 4, and described boss 43 tops are provided with the cavity of indent; Described rolling bracing or strutting arrangement is fixed in the cavity, and described rolling bracing or strutting arrangement links to each other with the bottom land of cavity bottom, groove 44 respectively.The cooperation deflection of boss 43 and groove 44 is little, permissible load is bigger, and can realize above-mentioned indent cavity easily.Above-mentioned rolling bracing or strutting arrangement is promptly adjusted driven roller assembling and is highly made the driven roller 31 top roll line position consistency of different size, be the mechanism of supports drive roller assembly weight, ring 10 weight, roll-force when rolling ring simultaneously, driven roller 31 tip positions are constant, corresponding ring 10 bottom level are constant, can be conveniently to the monitoring of ring 10 wall thickness.Rolling bracing or strutting arrangement can be hydraulic cylinder, screw mandrel, cylinder isoline driving mechanism.During work, by straight line driving mechanism driven roller is assembled jack-up, the driven roller assembling breaks away from the roll change bracing or strutting arrangement; During roll change, the straight line driving mechanism withdrawal is placed into the driven roller assembling on the roll change bracing or strutting arrangement.When rolling bracing or strutting arrangement adopts above-mentioned straight line driving mechanism, the driven roller assembling is switched on rolling bracing or strutting arrangement and roll change bracing or strutting arrangement switching mechanism between the two can directly be made of above-mentioned straight line driving mechanism.But owing to rolling when ring, weight that need be by rolling bracing or strutting arrangement supports drive roller assembling, ring 10 and bear roll-force, the device specification is big, is unfavorable for installing, be the support force that guarantees straight line driving mechanism, system consumption is big.And when adopting cylinder, hydraulic cylinder, because pressure oscillation causes rolling absolute altitude fluctuation, influence machining accuracy easily; And the employing screw body, the fit clearance of screw body is big, influences machining accuracy.
Support for simplified structure, assurance precision, reinforcement, described rolling bracing or strutting arrangement is absolute altitude adjusting pad 41 preferably, and is corresponding, and need be provided with independently switching mechanism this moment.Therefore, concrete, described rolling bracing or strutting arrangement is an absolute altitude adjusting pad 41, and described cavity is the adjusting pad chamber 45 that adapts with adjusting pad 41 sizes; Described adjusting pad 41 bonds are in adjusting pad chamber 45, and described groove 44 bottom lands are provided with cambered surface supporting pad 42; Insert groove 44 with boss 43, described adjusting pad 41 contacts with groove 44 bottom lands by the supporting pad 42 that inserts in the adjusting pad chamber 45; Described switching mechanism is the driven roller assembling lifting mechanism that is arranged between driven roller assembling and the frame or between driven roller assembling and the slide 4.Because lifting mechanism only needs to bear the weight of driven roller assembling when switching bracing or strutting arrangement, can be hydraulic cylinder, leading screw, jack etc., be provided with for convenience and operation, concrete, described lifting mechanism is four lifting hydraulic cylinders 49 that are fixed in frame, and described lifting hydraulic cylinder 49 positions are corresponding with four jiaos of driven roller assembling bottoms respectively; Described driven roller assembling bottom all is positioned at outside the slide 4 for four jiaos.Lifting mechanism can be arranged between slide 4 and the driven roller assembling, but this set-up mode can increase the difficulty that is provided with of fluid pressure line, increases the structural complexity of slide 4, and therefore best is arranged between driven roller assembling and the frame.
When rolling ring, driven roller assembles by rolling support construction supports, and rolling absolute altitude requirement is satisfied in the driven roller assembling; During roll change, by the assembling of lifting mechanism lifting driven roller, the slide 4 that slides then makes the supporting surface of rolling bracing or strutting arrangement and drive roller shaft bearing 32 stagger, after putting down driven roller assembling by lifting mechanism, the driven roller assembling is supported by the roll change bracing or strutting arrangement, and the axis constant height makes things convenient for roll change.
In order to adapt to the driven roller of different size, adjusting pad 41 is generally multilayer bond structure, though be provided with circumferentially spacingly between driven roller assembling and the slide 4, has the adjusting pad 41 stable hidden danger that differ from equally.Therefore adjusting pad 41 is arranged in the adjusting pad chamber 45 that adapts with its size, by contacting with adjusting pad 41 in the supporting pad 42 insertion adjusting pad chambeies 45, can guarantees the stability of sandwich construction under the load-bearing condition simultaneously.Supporting pad 42 adopts the cabochon supporting surface that possesses from bit function, can guarantee the good supporting condition.
The bond of adjusting pad 41 simultaneously in order to reduce the integral thickness of slide 4, makes structure further compact for convenience, and described boss 43 is arranged at slide 4, and described groove 44 is arranged at drive roller shaft bearing 32 bottoms.
When rolling bracing or strutting arrangement is arranged between driven roller assembling and the slide 4, the adjustable range lower limit of rolling bracing or strutting arrangement is subjected to the restriction of slide 4 and roll change bracing or strutting arrangement overhead height, in order to guarantee that adjustable range just needs to increase installing space, therefore the Compact Design that is unfavorable for equipment also is unfavorable for improving the stability of strutting system of rolling bracing or strutting arrangement.For fear of restriction to rolling bracing or strutting arrangement adjustable range, best, described rolling bracing or strutting arrangement is arranged between driven roller assembling and the slide 4, and described switching mechanism is the driven roller assembling lifting mechanism that is arranged between driven roller assembling and the frame or between driven roller assembling and the slide 4; Described drive roller shaft bearing 32 position corresponding with the roll change bracing or strutting arrangement is provided with the chamber of dodging of roll change bracing or strutting arrangement.Same as above, best described switching mechanism is to be arranged between driven roller assembling and the frame.
When rolling ring, driven roller assembles by rolling support construction supports, and the roll change bracing or strutting arrangement is positioned at dodges the chamber, and rolling absolute altitude requirement is satisfied in the driven roller assembling; During roll change, by lifting mechanism lifting driven roller assembling, slip slide 4, the roll change bracing or strutting arrangement with dodge the chamber and stagger, put down the driven roller assembling by lifting mechanism then, the driven roller assembling is by the support of roll change bracing or strutting arrangement, the axis constant height makes things convenient for roll change.
Concrete, described roll change bracing or strutting arrangement is a supporting pin 46, the described chamber of dodging is the pilot hole 47 that adapts with supporting pin 46 cross sections; Described supporting pin 46 tops are higher than the maximum height of rolling bracing or strutting arrangement, and described pilot hole 47 degree of depth are poor greater than rolling bracing or strutting arrangement maximum height and minimum constructive height.Described supporting pin 46 tops are higher than the maximum height of rolling bracing or strutting arrangement, have guaranteed that when roll change no matter the actual height driven roller assembling of rolling bracing or strutting arrangement all can be by supporting pin 46 supports; Rolling bracing or strutting arrangement maximum height and minimum constructive height poor, also promptly adjust the sliding stroke of supporting pin 46 in pilot hole 47 in the stroke at whole rolling absolute altitude, therefore pilot hole 47 degree of depth poor greater than rolling bracing or strutting arrangement maximum height and minimum constructive height, guaranteed that supporting pin 46 can not contact with at the bottom of pilot hole 47 holes in whole rolling absolute altitude adjustment stroke, thereby guaranteed that the driven roller assembling can be supported by rolling bracing or strutting arrangement when rolling.Therefore no matter why rolling bracing or strutting arrangement height is worth, and when rolling or adjustment driven roller assembling absolute altitude, all can cooperate with the formation guiding of pilot hole 47 by supporting pin 46.
Stable for what guarantee to support, described slide 4 is provided with at least four supporting pins 46, drive roller shaft bearing 32 respectively corresponding two supporting pins 46 at described driven roller assembling two ends.
Above-mentioned roll change bracing or strutting arrangement can be supporting constructions such as platform, piece also, but is unfavorable for the densification of structure.Also can be above-mentioned boss 43 itself, but this mode need manually to take out adjusting pad 41 before the driven roller assembling is put down, to guarantee contacting of boss 43 tops and groove 44 bottom lands, operation inconvenience.
Location when supporting by supporting pin 46 for further assurance is correct, guarantee the cooperation of circumferential position limiting structure, be provided with and the corresponding to supported hole 48 of pilot hole 47 cross sections, distribution and quantity, described supported hole 48 degree of depth are poor less than supporting pin 46 overhead heights and rolling bracing or strutting arrangement maximum height.When roll change, support supporting pin 46 tops and contacting at the bottom of supported hole 48 holes by 46 pairs of driven roller assemblings of supporting pin.When rolling bracing or strutting arrangement height is maximum, the difference in height minimum of rolling bracing or strutting arrangement and supporting pin 46, supported hole 48 degree of depth are poor less than this minimum constructive height, just can guarantee that the driven roller assembling breaks away from rolling bracing or strutting arrangement; Supporting pin 46 overhead heights are constant, and therefore along with the reduction of rolling bracing or strutting arrangement height, the difference in height of rolling bracing or strutting arrangement and supporting pin 46 increases, and can guarantee that the driven roller assembling breaks away from rolling bracing or strutting arrangement this moment equally.Therefore no matter why rolling bracing or strutting arrangement height is worth, and during roll change, the top of supporting pin 46 all can form support with contact at the bottom of supported hole 48 holes.
For further handled easily, described fore side frame 12 arranged outside have the haulage gear of slide 4, and described haulage gear links to each other by removably connecting with slide 4.Removably connecting can be by connections such as herringbone support, connecting rods, also can be that latch connects, bolt connects, link up with connection etc.Certainly haulage gear also can be arranged on the slide 4, but this moment unfavorable structure compactness.
Connect axle 14 enclasp devices to be provided with that the position sets according to supporting pin 46 apical side heights be that the roll change absolute altitude of driven roller assembling is determined, by be oppositely arranged a pair of hold piece 51 tightly and drive oil cylinder 52 form.During roll change, the driven roller assembling is supported by supporting pin 46, and slip between the machine frame at two sides with slide 4, driven roller homalocephalus 36, to connect axle 14 coaxial, can directly driven roller homalocephalus 36 be inserted connect and form being connected of driven roller 31 and transmission mechanism in the axle 14, after finishing being connected of slide 4 and frame, unclamp and hold piece 51 tightly, lift the driven roller assembling by lifting mechanism, slip slide 4 makes supporting pin 46 and pilot hole 47 aim at, put down the installation that the driven roller assembling can be finished the driven roller assembling by lifting mechanism, easy, quick.
