Description

Motion filament clamper and cutting association system

The filament that relate generally to of the present invention is reeled and cast continuously on rotation devices for taking-up by progressive forming processing technology.More specifically, the invention provides one by light wire pliers to the reel of the rotation on flywheel, cutting filament lead-out wire and by filament wound to wheel on equipment and method.

Vitreous or amorphous alloy has its unique physical characteristic to have great technical meaning compared with the performance forming with the polycrystalline of these alloys.The casting of the nature of glass structure particularly forming with the elongated band of filament or suitable book has guaranteed effectively in the iron core of the heavy duty detergent to power transformation device, to go or do other purposes.Some recent development casting non-crystal matter or glassy metal band are in 4332848 li of commentaries of United States Patent (USP).

As well-known in this specialty, nature of glass alloy promptly quenches or is cooled to solid noncrystalline solid-state from liquid state, generally has the degree of crystallinity that is less than about 50%.Quenching occurs in high cooldown rate, and 10 ⁶℃/sec the order of magnitude.Ribbon is to be generally expressed on a high speed cooling surface and to form through the limits nozzle of jet pipe by the molten alloy of self-pressurization in future container.Owing to preventing a large amount of crystallizations, require to be exceedingly fast geothermal transfer, the filament of casting must be book.

The filament of casting is fitly wound up in the storage wheel or rolling wheel of same Casting Equipment coordination, so that the latter is processed into transformer core or analog is necessary.But because casting speed is general high to approximately 1000 to 2000 meters per second, the starting of neat winding process is difficult.Therefore, the front part of high speed filament must be captured in the time that it leaves the cooling surface of quick rotation in the time of flight, then transmits and clamps on tape feed roller, is finally wrapped on wheel.Such typical device formerly by the people such as Smith (SMITH) 4116394 li of United States Patent (USP)s and by people such as Bo Gesi (BOGGS) in 4239187 li of explanations of United States Patent (USP).Reason it will be appreciated that because casting process carries out with fast speed very continuously at whole duration of work.Must realize fast and correctly clamper or promptly gather the coiling amount of filament.

Up to now, clamper filament is generally taked pivotally filament clamping part to the clamp mechanism in storage wheel, so that the form of rotating together with storage wheel (seeing Smith's 394 patents).Clamping part comprises the movable clamping tool forming together with a cutting edge with a clamping area, and this movable cutting edge matches with the upper static cutting edge of wheel.In the time driving, clamping tool is that device must rotate on pivot, and is pasting wheel and vising filament.Match device cut filament simultaneously and draw by force line end at the filament of foundry goods one side of two cutting edges.

But disadvantageously, Smith's device is providing normal failure on necessary clamping and cutting action reliably to filament.In the time not supplying with suitable cutting action, the lead-out wire of filament is just pulled back on reel and destroys filament wound.In other situations, cutting action is just to occur early than clamper action rather than with clamper action rather than with clamper action simultaneously.In the time that this thing happens, filament just slips away between clamping tool and wheel, becomes soon a glob of of winding.Any failure above all can cause that casting process and cleaning procedure are deadlocked, and causes very large loss.Past, because the pause that is forced to of casting process declines productivity ratio, has become the business-like significant obstacle of amorphous metal casting technique.In addition, insecure cutter sweep of Smith is difficult for proofreading and correct.Many tests, as if strengthen the active force of fixture upper spring, provide between two cutting edges and mate preferably, and sharpen cutting edge, all failed for increasing reliability.Metal ribbon, because its characteristic is very tough, just contributes to pull open two cutting edges, therefore ribbon pinching between two cutting edges and not cutting.In other situations, cutting action can, prior to constant clamping action part second, make the ribbon in the situation that stretching tight quite tightly be drawn pine, causes winding process to be out of order.The complexity that multi-part mechanism increases has also increased production cost and the general requirement of safeguarding.And, in the time that reel rotates with friction speed, the clamping force of the clamping tool being provided by spring can not compensating action in the different rotatory force that is fixed on the clamping tool in enable possition.Thereby, in previous device, must accurately arrange time of loosening, loosening up is occurred in identical speed at every turn.Otherwise clamping tool arrives and clamps filament or too early, or too late.This just places contact point to such an extent that leave optimum position, and in optimum position, filament is settled to such an extent that contact with reel by carrying device, and in these cases, clamper and dissection can be made mistakes, and cause casting process to be out of order.Therefore must and cut lead-out wire in the rolling wheel of hand winding filament to rotation or storage wheel time, establish one and provide the clamper of larger reliability and the equipment of cutting and method.

So primary and foremost purpose of the present invention is to provide a kind of equipment and method, to improve, hand primer is reeled casting silk on the storage wheel of rotating and the reliability of cutting filament lead-out wire.

It is less and cutting edge is not matched that another object of invention is to provide parts, and not too complicated clamper and cutting equipment, to improve reliability and to maintain smooth running.

Another object of the present invention is to provide a self-compensating clamper and cutting equipment for the variation of rolling wheel rotary speed, to the clamping force that is proportional to rolling wheel rotary speed is provided, filament is made to suitable clamper and cutting action.

Another object of the present invention is to provide a simple mechanism.The filament of casting with clamper, on the rotation storage wheel of flight, then cuts the lead-out wire of filament.

A further object of the present invention is to provide a kind of method and apparatus, and wherein in the time that storage wheel is rotated, cutting action relies in company with filament being had constant and having the single blade freely of the device of forcing clamper action to occur on filament.

The other object of invention, advantage and other novelty somes show in the following description, a part of become clearly according to analysis below for the people who is skilled in technique or along with working of an invention can be understood.The object of invention and advantage can realize and obtain with the various means that particularly point out in subordinate claim and combination thereof.

In order to reach the above-mentioned object with other, and with object of the present invention is consistent as described below, the casting silk of advancing for clamper, to the rolling wheel of rotation, then excises the lead-out wire of filament and the equipment having improved is provided.Clamper and cutting equipment comprise that is installed to obtain the parts that are combined of the clamper of rotating with rolling wheel and cutting.Parts comprise that has a free cutter sweep, the movable clamper arm of for example blade, and cutting edge is placed on rolling wheel axle, and installs to the side of clamper arm in the face of filament direct of travel.Clamper arm grips filament at first securely, and has moved to the position of dissection at firm grip rear knife edge.

Drive unit is used for making clamper arm from the position of unlatching of leaving rolling wheel to closed position, and in this position, clamper arm engages in clamper with the filament on axle.In closing position, clamper arm is used for the filament of advancing to be clamped on the rolling wheel of rotation, thereby filament wound is stored to taking turns above and entering in reel.

In addition, as if a such device of device matching relative to two brush rolls of also anti-phase rotation is used for pasting the cutting edge finedraw lead-out wire of clamper arm in the time that rolling wheel rotates, its effect is to guarantee only after filament is clamped on rolling wheel securely, forcibly, just to cut.Due to this effect, just obtain safe clamper and cutting action successfully to make winding process start to carry out, equally also successfully reduce the downtime of casting, in the time using the device of previous technology, shutdown is common.

More preferably drive unit comprises a gearshift that is applicable to clamper arm to move to from enable possition closing position, and a centrifugal weight also comprises that a folder treats device or parts, to resist displacement weight, releasedly clamper arm is fixed on to enable possition.And drive unit and then comprise a starting drive, such as lever, for loosening hold assembly, so that the weight of license displacement moves to closing position by clamper arm from enable possition, thereby vises filament and it is clamped on reel.

Invent the aspect into one deck, according to its object and meaning, disclose filament that a clamper advances or analog to the rolling wheel rotating, the method for then cutting filament lead-out wire.The first step is from the casting surface of the rapid movement above wheel shaft and through rolling wheel tension and pull-out filament.A pliers of two counterrotating brush roll compositions receives filament and can be used as this purpose.Filament is after the drop-down rolling wheel excessively of tensioned state, by making filament generation clamper by the method that the parts that clamper and cutting are combined drive filament to be meshed with wheel.Next step is the action of pasting free cutting edge finedraw.The action of this towing can be provided by for example identical with conveyer for filament being pulled through to rolling wheel conveyer.When wheel turns and drive clamper and the cutting edge of cutting part enters while engaging with filament lead-out wire, towing causes cutting action.And, favourable have be, cutting action filament soundly and forcibly clamp after on wheel, just provide, to guarantee that winding process starts steadily.

Along with following description, other the object that the present invention also has has just become apparent for those professional and technical personnel.Below show and described a most preferred embodiment of the present invention, simply as the explanation that is most appropriate to a mode carrying out invention.As carried out this most preferred embodiment, invention can have other different embodiments, and its some details are allowed and done various, the significantly modification of form aspect, do not depart from the present invention.So accompanying drawings and description are all regarded common explanation as and are not restricted.

Now, at length, with reference to most preferred embodiment of the present invention, follow accompanying drawing that its example is described.

With reference to Fig. 1, it represents an amorphous metal continuous casting system [10], can (1) cast filament by it; (2) in the time of flight, capture filament; (3) strain filament and be sent on rolling wheel; And (4) by filament wound in reel.As illustrated, the alloy of melting comes out to the cooling surface or cylinder [14] of rapid movement from spinning head [12] extrusion, to form filament [16], along with casting process, filament [16] is conventionally captured and strained by the specified carrying device of reference numerals [18].In three positions of Fig. 1 and Fig. 2, filament transmission is also wound up on the rolling wheel [20] of rotation.

Turntable [21] is also with another one rolling wheel [20a] (see figure 2), and after the process that uses rolling wheel [20] to reel completes, turntable [21] indexing is with location rolling wheel [20a] filament of reeling.

As illustrated, carrying device [18] comprises two opposition counterrotating brush roll [22], and composition one pliers receives filament [16].It is upper that brush roll [22] is contained in framework [24], and be connected to (not shown) on the CD-ROM drive motor of associated brush roll.Brush roll [22] rotates to move than independent filament speed fast, so that filament constantly crosses and slippage, thus desired tension situation when remaining on filament [16] and advancing.Tension makes the filament between brush roll [22] and casting surface [14] eliminate harmful loosening and swing.Result is that the mode that filament can be clamped down on is arranged on the axle of rolling wheel [20], goes with being wound up in reel in order to clamper.

The element of above-mentioned carrying device [18] can be generically and collectively referred to as spiral head [28].Spiral head [28] is by two tubular supporting bars [30] vertical support, and support bar [30] can vertically slide by the inner pipeline of transfer member [32].The upper end of support bar [30] is fixed to that cam follow-up part [34] is upper, and cam follow-up part [34] has a rolling drawing bearing, follows the trail of in order to the cam profile [36] of the cam disc [38] that supports along U-shaped framework [40].

Transfer member [32] can cross framework by common cylinder (not shown) or any other the drive unit in known technology and flatly drive.In the time that transfer member [22] was crossed framework driving, cam follow-up part [34] is above followed the trail of towards position B at cam profile [36], as shown in perspective view (Fig. 1), cause like this tubular supporting bar [30] vertically to slide, and swimmingly by transfer member [32], to make spiral head [28] towards rolling wheel [20] and in rolling wheel [20] top motion (Fig. 2).Then,, after filament [16] is pulled through rolling wheel [20], in the time that cam follow-up part [34] is followed the tracks of cam profile [36] downwards, spiral head [28] just drives downwards.This causes, and filament [16] is firm to be also placed on the wheel hub [42] of rolling wheel [20] forcibly.In this position, brush roll [22] rotates continuously with the form of overrun, to suitably strain filament [16] finedraw lead-out wire suitably to cut, this will at length discuss below.

Be pulled through rolling wheel [20] and pull down at filament [16], thereby after contacting securely with wheel hub [42], relying on spiral head [28], clamper of the present invention and cutter sweep [50] just start (seeing Fig. 3 and Fig. 4).Clamper and cutter sweep [50] first provide the clamper action of a clamper filament [16] to rolling wheel [20], then provide a cutting action to cut to the filament lead-out wire from rolling wheel, thereby make coiling action stably avoid being destroyed by lead-out wire.

As illustrated, clamper and cutter sweep [50] comprise that one is contained in the inner clamper of rolling wheel [20] body [53] above and cuts the parts [52] that are combined, and clamper and cutting part [52] comprise a movably clamper arm [56] linking with turning cylinder [57].Nobelium position arm [56] comprises a free cutting edge [58], and its contiguous clamper arm is in the face of spool or the coiling surface [42] of filament [16] direct of travel one side, and side placed on it (noting Fig. 4,5 and 6).Clamper arm [56] is also equipped with the lower surface of an arc, in order to firmly to embed and to vise filament [16] in the groove of corresponding wheel hub [42].

Drive unit rotates rotating shaft [57], and makes clamper arm [56] from the enable possition (being shown in the dotted line of Fig. 4) of wheel hub [42] of leaving rolling wheel [20] to closing position (being shown in solid line), and there, clamper arm engages in clamper.In closing position, clamper arm [56] gets on to rolling wheel [20] for firmly also vising forcibly filament [16].As shown in the figure, drive unit also comprises that as if one the such displacement facility of centrifugal weight [59], be applicable to clamper arm [56] to produce a self-compensating closing force, to permit the operation of successfully doing clamper and cutting without adjusting in the wide velocity interval of rolling wheel [20] rotation.Weight [59] is slidably mounted in to be justified in hole [60], and it is upper that cylindrical hole [60] is radially stretched over rolling wheel [20] in body [53], like this, in the time that rolling wheel [20] rotates, leaves rolling wheel [20] and outwards moves justifying weight in hole [60] with centrifugal force.Closed clamper arm [56] is exactly to use this centrifugal force, and this is undertaken by weight [59] being connected to turning cylinder [57] with cable wire [61].

As shown in Figure 4 and Figure 6, one end of cable wire [61] be wrapped in drive clamper arm [56] turning cylinder [57] around, cable wire [61] other end is connected with weight [59].In the time that centrifugal weight [59] leaves rolling wheel [20] and outwards moves in cylindrical hole [60], it pulls cable wire [61] to be connected to the one end on turning cylinder [57].Like this, cable wire [61] is just converted to the torque for turning cylinder [57] at the upper centrifugal force producing of weight [59] when rolling wheel [20] is rotated.Turning cylinder [57] successfully rotates in bearing block [57a].The rotation of consequent turning cylinder [57] is arrived rolling wheel [20] for closed clamper arm [56] by filament [16] pincers.

Drive unit also comprises a hold assembly [62], and parts [62] comprise the groove [64] that can decontrol the clamper arm in enable possition that holds clamper arm [56].

Further again, drive unit also comprise one by mark from the specified common actuating mechanism of number [66].Actuating mechanism [60] is applicable to loosen hold assembly [62] so that license centrifugal weight [59] outwards moves cylindrical hole [60] is inner.And turning cylinder [57] is rotated, and cause clamper arm to move and enter closing position (as shown in accompanying drawing solid line), particularly, starting drive comprises that one is utilized pin [74] to be contained in the screwed pipe [68] on stand [76], screwed pipe bar [70] and control stick [72].When wanting filament wound on rolling wheel [20] time, to drive screwed pipe [68], drive screwed pipe bar [70] and control stick [72] (is dotted) forward to enable position (representing with solid line) around pivot from enable possition.In enable position, control stick [72] is encountered clamping element [62], and it is rotated around pin [78], thereby clamper arm [56] is released from groove, then just outwards motion in cylindrical hole of centrifugal weight [59], this motion is drawn cable wire [61] from turning cylinder [57], thereby causes that turning cylinder [57] rotates, and it (represents) for embedding filament [16] and clamping filament [16] to rolling wheel [20] clamper arm [56] with solid line from enable possition (dotting) along arrow A direction to closing position.

As shown in Figure 3 and Figure 4, actuating mechanism [66] is to be placed in along the time controlled position on rolling wheel [20] rotation approach top to run into above and decontrol hold assembly.This just guarantees when rolling wheel [20] is during in one run-on point, clamper arm [56] closure and vise filament, and in that, the free cutting edge [58] of cutting arm is to put a coiling surface or spool [42] above, and leaves filament (seeing Fig. 5 A).Therefore, clamper of the present invention and cutter sweep [50] originally only provide a clamper action, and clamping filament [16] gets on to rolling wheel [20].

Advantageously, do not resemble prior art actuating device of the spring, the power of being supplied with closed clamper arm by centrifugal weight [59] is directly proportional to the velocity of rotation of rolling wheel [20].For example, in the time that rolling wheel [20] does not turn, centrifugal closing force is zero.Certainly install conveniently and safely again the enable possition that, this license clamper arm [56] is held parts [62] embedding at it.Know that light spring [79] can be used for the inner centrifugal weight [59] of displacement cylindrical hole [60], in the time again installing clamper arm [56] operation to antigravity.And because provided closing force is proportional to the velocity of rotation of rolling wheel [20], rolling wheel [20] rotates sooner, be added to power on clamper arm [56] by centrifugal weight [59] and cable wire [61] just larger.Like this, centrifugal weight [59] compensates and offsets and tries hard to make clamper arm [56] directly to come out to the rotatory force of enable possition from rolling wheel [20].The rotatory force that these opposing clamper arms [56] are closed increases along with velocity of rotation just.And, being provided by centrifugal weight [59], the closing force increasing in the time that rolling wheel velocity of rotation increases is used for closed clamper arm [56] quickly.Like this, even in a very large velocity interval, the present invention guarantees to provide the action of suitable clamper and before free cutting edge contact filament, clamps filament [16] to rolling wheel [20] get on (attention Fig. 5 A).

But, after clamper, when wheel [20] is in the time that the direction of arrow of Fig. 5 A-5C is rotated further, filament lead-out wire [80] by spiral head [28], rotate brush roll [22] and move the cutting edge [58] (Fig. 2 and Fig. 5 are combined and seen) that is pasting clamper arm [56] to.This is the filament lead-out wire [80] from rolling wheel [20] for cut-out, thereby the unlikely destruction filament of lead-out wire [16] is wound up on wheel reposefully.The filament head [80] cutting draws the roller [22] through rotating and throws on one side.

Summarize in fact, owing to having used principle of the present invention, narrate out many benefits.Particularly, in the process in the time that the storage wheel [20] that the filament of advancing [16] is wound up into rotation gets on, provide a single mechanism to complete respectively clamper and two functions of cutting.Advantageously, the present invention includes the part of minimal number, thereby more reliable and lessization take, and provide the mechanism of separation to complete separately the function of clamper and cutting.In addition, device [50] originally firmly, forcibly by filament [16] pincers to rolling wheel [20] above, then cuts off filament lead-out wire [80], to guarantee reposefully, trouble-freely to reel filament.Also should admit, due to the cutting edge that does not need to match, avoid adjusting cutter irregular working improper and that cause thus.Due in the time that rolling wheel [20] merely rotates to reel filament, the brush roll [22] of rotation forces finedraw pasting the cutting edge of clamper arm [56], has guaranteed the function of cutting by equipment of the present invention and method.

Introduced a most preferred embodiment of the present invention by illustration and text description above, it is not confirmed as perfect, does not intend invention to be restricted to disclosed specific open type yet.By above technology, may do various modifications and conversion.Select and describe embodiment for the principle and the practical application thereof that illustrate best invention, thereby these professional those skilled in the art can will be invented for various embodiment.And do various conversion to be applicable to desired special purposes.In the time explaining according to just, legal, the rational width of subordinate claim of the present invention, all these improvement and conversion are all in the present invention the scope by subordinate claim defined.
