Uppfinnare: C Brooks Prioritet begard iron den 16 december 1958 (Storbritannien) Foreliggande uppfinning avser ett fOrfarande for behandling av lindade metallband for att avlagsna andpartier dal-dram efter reverserad valsning av bandet. Uppfinningen har till andamal att astadkomma en forbattrad procedur for att Iran sadana band och saxskilt fran hasplade band av rostfritt stAl eller annat legerat sta.l avlagsna de andpartier, vilka befinna sig i den framre och bakre anden av bandet, dà detsamma kallvalsats i ett valsverk av reverseringstyp. Inventor: C Brooks Priority Begard Iron December 16, 1958 (United Kingdom) The present invention relates to a process for treating wound metal strips to remove duct portions of dal-dram after reverse rolling of the strip. The object of the invention is to provide an improved procedure for removing such ducts and scissors separately from reels of stainless steel or other alloy steel from the duck portions which are in the front and rear ends of the belt, when the same is cold rolled in a rolling mill. of reversal type.

Dessa andpartier utgora ovalsade delar och bilda ett nodvandigt komplement till valsningen pa grund av placeringen av de hasplar, som forsatta bandet under spanning och vilka anvandas under valsningen pa vardera sidan om valsverket. Andpartierna medgiva att huvuddelen av bandet kan valsas, men nar detta ar gjort, maste desamma avlagsnas innan den ytterligare behandlingen av bandet, exempelvis mjukning, avlagsnande av valshud eller liknande, kan verkstallas. Andpartierna kunna utgora integrerande delar av bandmaterialet eller bilda separata enheter, som fastsvetsas vid andarna av bandet. I det senare fallet kunna de utgoras av annat material an bandet, ehuru det är valkant att pa nytt anvanda gamla andpartiet. These duck portions form unrolled parts and form a necessary complement to the rolling due to the location of the reels which continued the belt under tension and which are used during the rolling on each side of the rolling mill. The duck parts allow the main part of the strip to be rolled, but when this is done, they must be removed before the further treatment of the strip, for example softening, removal of roll skin or the like, can be carried out. The duct portions can form integral parts of the strip material or form separate units, which are welded to the spirits of the strip. In the latter case, they may be made of a material other than the tape, although it is optional to reuse the old duck part.

Den vanligaste metoden for avlagsnande av andpartierna frail det valsade bandet har varit att linda av den framre eller yttre amidelen frau bandet i hasplat tillstand after valsningen, avskara densamma frail den valsade delen av bandet genom maskinell skjuvning och darefter linda av det valsade materialet och Ater phhaspla detsamma pa en dorn, varvid den bakre eller inre anden avlagsnas ph liknande sat. The most common method of removing the duck portions from the rolled strip has been to unwrap the front or outer amide from the strip in a hapless state after rolling, cut the same portion from the rolled portion of the strip by mechanical shearing and then wrap the rolled material and reapply it. the same on a mandrel, in which case the ph of the rear or inner spirit is deposited similarly.

Denna metod och andra tidigare tillampade metoder aro dyrbara och tidskravande och resultera i en nAgot Overdriven behandling av ett material, vilket, atminstone dá det är fraga om band av rostfritt stAI eller annan stallegering, maste saljas sAsom en produkt av hog kvalitet och frill fan felaktigheter. This method and other previously applied methods are expensive and time consuming and result in a somewhat excessive treatment of a material which, at least in the case of stainless steel strips or other stable alloy, must be sold as a product of high quality and free from defects. .

Dessa olagenheter elimineras emellertid genom uppfinningen som i huvudsak kannetecknas av att bandrullen anbringas pa en avhaspel, att bandet matas fran denna haspel genom en skjuvningsanordning till en lindningsmaskin for den framre eller yttre anddelen eller andpartiet, att skjuvningsanordningen paverkas for att avskilja delta parti vasentligen after det att detsamma lindats av maskinen, varefter bandet fores framat in i apparater for ytterligare behandling, exempelvis mjuknings- och/eller avskalningsapparater, varvid skjuvningsanordningen Ater paverkas nar den framre anden av den inre eller bakre anddelen eller andpartiet uppndr eller vasentligen uppnar densamma i och for avskiljning av namnda andparti samt att den inre eller bakre anddelen eller andpartiet dh lindas tillbaka ph avhaspeln. However, these inconveniences are eliminated by the invention which is mainly characterized by the belt roll being mounted on a reel, the belt being fed from this reel through a shear device to a winding machine for the front or outer portion or the duct portion, the shear device being actuated to separate the delta portion substantially thereafter. that the same is wound by the machine, after which the belt is fed forward into apparatus for further treatment, for example softening and / or peeling apparatus, whereby the shearing device Ater is affected when the front end of the inner or rear end portion or the end portion changes or substantially reaches the same for separation. of said duck portion and that the inner or rear duck portion or duck portion dh is wound back ph avhaspeln.

Uppfinningen avser aven en apparat for utforande av forfarandet enligt uppfinningen vilken i huvudsak kannetecknas av att den bestar av en avhaspel foljd av en motordriven skjuvningsanordning och en lindningsmaskin for andpartiet i denna ordning, varvid maski- 2 nen har en grupp valsar, vilka aro anordnade att forma den framre eller yttre anddelen eller andpartiet av bandet till en rulle, samt drivna spannvalsar pa vane sida av kombinationen Indian motordriven skjuvningsanordning och lindningsmaskin. The invention also relates to an apparatus for carrying out the method according to the invention, which is mainly characterized in that it consists of a reel followed by a motor-driven shear device and a winding machine for the duck portion in this order, the machine having a group of rollers, which are arranged to forming the front or outer end portion or the end portion of the belt into a roll, as well as driven tension rollers on the usual side of the combination Indian motor-driven shear device and winding machine.

Ett utforingsexempel pa uppfinningen kommer nu att beskrivas med hanvisning till bifogade schematiska ritning. An embodiment of the invention will now be described with reference to the accompanying schematic drawing.

Fig. 1 askadliggar det stag under utforandet av metoden enligt uppfinningen i vilket det framre andpartiet just skall avskaras fran bandet. Fig. 1 shows the stay during the execution of the method according to the invention in which the front duck portion is just to be cut off from the belt.

Fig. 2 askadliggar det steg under processen, van i den bakre anddelen eller andpartiet just skall avskaras frail bandet. Fig. 2 ashes the step during the process, used in the rear duck part or the duck portion just to be cut from the belt.

I den askadliggjorda anordningen innefattar apparaten i foljande ordning en avhaspel 1, ett par spannvalsar 2, en maskindriven skjuvanordning 3, en lindningsmaskin 4 for den framre anddelen eller andpartiet 5, en elektrisk punktsvets- eller somsvetsanordning 6 on ett par dragande spannvalsar 7, varvid dessa enheter omfatta ingangsdelen i en mjuknings- eller avskalningslinje i en lamplig eller kan.d form (icke visad). Pa andra sidan de dragande spannvalsarna 7 kan forefinnas ytterligare ett par liknande valsar 8 (besthende om sa anskas av initiella spannvalsar i den efterfoljande mjuknings- eller avskalningslinjen), vilka, out sa onskas, tillsammans med andra valsar (icke visade) majliggora, att bandet 9 antingen befriat fran sitt framre a.ndparti 5 eller darefter genom svetsanordningen 6 forenat med den bakre anden av ett tidigare iordningstallt band 0 han formas till en nedhangande slinga 9a for att ackumulera band fore dess passage till mjukningsugnen och de kemiska reningsbaden i mjukningsoch avskalningslinj en. In the ash-damaged device, the apparatus comprises in the following order a unwinding reel 1, a pair of clamping rollers 2, a machine-driven shear device 3, a winding machine 4 for the front end part or the duct portion 5, an electric spot welding or somswelding device 6 and a pair of pulling clamping rollers 7, units comprise the input part of a softening or peeling line in a suitable or similar form (not shown). On the other hand, the pulling tension rollers 7 may be provided with a further pair of similar rollers 8 (consisting, if desired, of initial tension rollers in the subsequent softening or peeling line), which, if desired, together with other rollers (not shown) allow the strip 9 is either freed from its front end portion 5 or thereafter by the welding device 6 joined to the rear end of a previously prepared strip 0 it is formed into a hanging loop 9a to accumulate strips before its passage to the softening furnace and the chemical purification baths in the softening and peeling line. .

Lindningsmaskinen 4 for andpartierna be-star i forsta hand av ett par spannvalsar 10 far bandet, en grupp av Ire bojande valsar 11, 12, 13 och ett par vagga bildande valsar 14 anordnade ovanfor de bOjande valsarna. Samtliga valsar aro pa lampligt satt lagrade och omslutna och spannvalsarna 10 och de bojande valsarna 11, 12, 13 aro motordrivna. Det torde inses, att maskinen är avsedd att linda den yttre anddelen eller andpartiet 5 uppat fran de bojande valsarna till valsarna 14. Detta utfores vasentligen fore avklippningen av partiet 5 frail bandet 9 medelst skjuvanordningen 3. Den bojande valsen 12 Or belagen centralt Over de andra ba.da valsarna 11 och 13 for att astadkomma en triangular placering av de tre. Valsen 12 är installbar upp och ned och paverkas for att b8ja andpartiet 5 nedat i nagon man for att pabOrja lindningen av detsamma. Andpartiet erhaller upptill formen av en oppen eller los slinga (se fig. 1), som vilar pa de hada vagga bildande valsarna 14, varvid slingans form underlattar behandlingen och upplagringen av andpartiet fore anvandning pa nytt. Skjuvanordningen 3 pdverkas for att avklippa andpartiet fran bandet strax efter det att den bakre anden av andpartiet passerat darigenom. The winding machine 4 for the duck portions consists primarily of a pair of tensioning rollers 10 from the belt, a group of Irish bending rollers 11, 12, 13 and a pair of rock forming rollers 14 arranged above the bending rollers. All rollers are suitably mounted and enclosed and the tension rollers 10 and the bending rollers 11, 12, 13 are motor driven. It will be appreciated that the machine is intended to wind the outer end portion or end portion 5 upwardly from the bending rollers to the rollers 14. This is essentially performed prior to cutting the portion 5 from the belt 9 by means of the shear device 3. The bending roll 12 or coated centrally over the others both rollers 11 and 13 to achieve a triangular placement of the three. The roller 12 is installable up and down and is actuated to bend the duck portion 5 downwards in any man to begin the winding thereof. The duct portion obtains at the top the shape of an open or loose loop (see Fig. 1), which rests on the had rock forming rollers 14, the shape of the loop facilitating the treatment and storage of the duck portion before reuse. The shear device 3 is actuated to cut the duck portion from the belt shortly after the rear spirit of the duck portion has passed therethrough.

Efter lindningen och avklippningen av det yttre andpartiet aterfores den installda bojande valsen 12 till dess initiallage (se fig. 2), sa all bandet 9 med anden 5 avlagsnad passerar i en rak linje horisontellt genom gruppen av bajande valsar 11, 12, 13 for att i svetsanordningen 6 forenas med det fOregaende ban.det 9. After the winding and cutting of the outer duct portion, the installed bending roller 12 is returned to its initial position (see Fig. 2), so that all the belt 9 with the duct 5 removed passes in a straight line horizontally through the group of bending rollers 11, 12, 13 to in the welding device 6 is combined with the previous band 9.

Den inre eller bakre anddelen eller andpartiet 15 fares icke till lindningsmaskinen 4. Detta andparti avklippes, sedan den averva.- gande delen av bandet 9 passerat framat fran lindningsmaskinen fran bandet, nar den framre anden av andpartiet narmar sig skjuvningsanordningen och lindas tillbaka pa avhaspelns dorn 1, fran vilken den avdrages i sling-form for magasinering for att anvandas pa nytt. Darefter placeras en ny bandrulle pa avhaspeln for avlagsnande av andpartiet enligt vad som beskrivits osv. for att mojliggora kontinuerlig drift av mjuknings- och avskalningslinj en. The inner or rear end portion or end portion 15 is not fed to the winding machine 4. This end portion is cut off after the predominant portion of the belt 9 has passed forward from the winding machine from the belt when the front end of the end portion approaches the shear device and is wound back on the reel mandrel mandrel. 1, from which it is subtracted in loop form for storage for reuse. Then a new belt roll is placed on the reel for removing the duck portion as described and so on. to enable continuous operation of the softening and peeling line.

De beskrivna operationerna for avlagsnande av andpartiema medfora endast ringa extratid for utforandet jamfort med den lid, som vanligen tages i ansprak vid matning av en rulle berovad sina andpartier genom intra.dessektionen i kanda mjuknings- och avskalningslinjer. Detta innebar givetvis, att den tidigare namnda slingan 9a, vilken Or avsedd for ackumulering av tillracklig matning for mjuknings- och avskalningslinjen, maste uppsamla na.got extra band, men detta Or av mindre betydelse jamfort med de hanteringssvarigheter, som meta vid de tidigare godtagna metoderna for avklippning av andpartier. Ingen okning av totaltiden far passagen av bandet genom mjuknings- och avskalningslinjen per langdenhet av material under behandling beh8ver medraknas, eftersom produktens hastighet fran avhaspeln till slingan eller slingorna med latthet kan okas for att erbjuda den erforderliga extra kapaciteten. The described operations for removal of the duck portions entail only little extra time for the execution compared with the lid, which is usually used when feeding a roll deprived of its duck portions through the intra-dissection in known softening and peeling lines. This meant, of course, that the previously mentioned loop 9a, which is intended for the accumulation of sufficient feed for the softening and peeling line, must collect some extra tape, but this is of less importance compared to the handling durations measured by the previously accepted the methods for cutting duck parts. No increase in the total time the passage of the belt through the softening and peeling line per unit length of material under treatment needs to be taken into account, as the speed of the product from the unwinding to the loop or loops can be easily increased to offer the required extra capacity.

Uppfinningen Or icke begransad till den salunda sarskilt beskrivna utforingsformen pa apparaten, eftersom modifikationer Oro mojliga, utan att man avlagsnar sig fran uppfinningens ram. Exempelvis kan lindningsmaskinen konstrueras for att linda den yttre anddelen eller andpartiet nedat i stallet for uppat och tat lindning av detta andparti 3 en dorn kan mojliggoras i denna maskin i stallet for 18sa vary, om sd. onskas. Vidare kunna andra maskinformer an svetsapparater anvandas for att ftirena den framre anden ay bandet, som är berovad sitt yttre andparti yid ett tidigare iordningstallt band. The invention is not limited to the embodiment of the apparatus thus specifically described, since modifications are possible without departing from the scope of the invention. For example, the winding machine may be designed to wind the outer duck portion or duck portion down in the stall for up and down winding of this duck portion 3 a mandrel may be enabled in this machine in the stall for 18sa vary, if sd. onskas. Furthermore, other machine shapes than welding apparatus can be used to clean the front end of the belt, which is deprived of its outer end portion by a previously prepared belt.
