i 146499in 146499
Opfindelsen omhandler et apparat til smedning af krumtap-aksler af den i krav l's indledning angivne art, der er kendt fra beskrivelserne til fransk patent nr. 994 026 og dettes tillægspatenter nr. 56 233 og 61 415.The invention relates to an apparatus for forging crankshafts of the kind specified in the preamble of claim 1, which is known from the disclosures of French Patent Nos. 994,026 and its Additional Patents Nos. 56,233 and 61,415.
I de kendte apparater anvendes der kraftige donkrafte til at kunne modstå separationskraften imellem de øvre og de nedre sænker, hvilken kraft modvirker den af smedepressen udøvede kraft.In the known apparatus, powerful jacking is used to withstand the separation force between the upper and lower lowers, which counteracts the force exerted by the forging press.
Opfindelsen har til formål at udnytte skråfladerne til ud -øvelse af separationsmodkraften. Dette opnås ifølge opfindelsen ved en konstruktion af den i krav l's kendetegnende del angivne art.The invention has for its object to utilize the inclined surfaces for exercising the separation counter-force. This is achieved in accordance with the invention by a construction of the kind specified in claim 1.
Herved udnyttes den lodrette kraftkomposant imellem skråfladerne til at modstå separationskraften og den vandrette kraftkomposant til at fremkalde den vandrette forskydning af slæderne. Smedepressens kraftudøvelse udnyttes fuldt ud, og man kan nøjes med svage donkrafte, der ikke skal udøve et permanent fastklemningstryk på sænkerne, men kan tjene til ved smedningens begyndelse at fastholde de øvre sænkebærere i en nederste stilling, hvorefter skråfladerne overtager udøvelsen af den lodrette kraftkomposant .Hereby, the vertical force component between the inclined faces is utilized to withstand the separation force and the horizontal force component to induce the horizontal displacement of the slides. The forging press power is fully utilized and weak jacking is required, which is not to exert a permanent clamping pressure on the lowers, but can serve to hold the lower submersible in a lower position at the beginning of the forging, after which the inclined surfaces take over the exercise of the vertical power pouch.
Opfindelsen forklares nærmere nedenfor i forbindelse med tegningen, hvor: fig. 1 viser de virkende kræfter imellem skråfladerne på en travers 0g på en tilsvarende slæde i apparater af den omhandlede art, og fig. 2 og 3 er længdesnit igennem apparatet ifølge opfindelsen henholdsvis før og under smedningen.The invention is further explained below in connection with the drawing, in which: FIG. 1 shows the acting forces between the inclined surfaces of a traverse 0g on a corresponding sled in apparatus of the kind in question, and fig. 2 and 3 are longitudinal sections through the apparatus according to the invention before and during forging respectively.
Som vist på fig. 1 udøver i apparater af den omhandlede art 2 U6499 en skråflade 47 på apparatets travers mod skråfladen 65 på den overfor liggende sænkebærer en skråt rettet kraft F^, hvis vandrette komposant H bevirker sænkebærerens vandrette bevægelse. Derimod overføres den lodrette komposant til pressens nedre bærebjælke over sænkebærerne og apparatets stativ. Denne lodrette komposant, hvis værdi er af samme størrelsesorden som den vandrette komposants, har derfor ingen nyttig virkning. I sænkebærerne er de nedre sænker og de øvre sænker holdt på plads af donkrafte . Disse ligger an mod undersiden af traversen, som overfører sit reaktionstryk direkte til pressens bevægelige travers og således søger at modvirke dennes sænkning.As shown in FIG. 1, in apparatus of the type 2 U6499, an inclined surface 47 on the traverse of the apparatus against the inclined surface 65 of the opposite lower carrier exerts an oblique directed force F1, whose horizontal component H causes the horizontal movement of the lower carrier. In contrast, the vertical component is transmitted to the lower support beam of the press over the lower supports and the apparatus stand. Therefore, this vertical component, whose value is of the same order of magnitude as the horizontal component, has no useful effect. In the lower carriers, the lower lowers and the upper lowers are held in place by jacking. These abut the underside of the traverse, which transmits its reaction pressure directly to the movable traverse of the press and thus seeks to counteract its lowering.
Selv om virkningerne af donkraftene ikke er særlig fremtrædende ved den i fransk patent nr. 994 026 beskrevne frie fibrering, vil de ved fibromatricering blive meget store, og deres sum svarer til det maksimale tryk, der er nødvendigt for emnets stukning.Although the effects of the jackets are not very prominent in the free fibration described in French Patent No. 994 026, they will be very large in fibromatization and their sum corresponds to the maximum pressure required for the workpiece cracking.
Ifølge opfindelsen erstattes virkningen af donkraftene af den lodrette komposant V, der overføres fra traversens skråflader til de overfor liggende skråflader på de øvre sænkebærere.According to the invention, the effect of the jacking is replaced by the vertical component V, which is transferred from the inclined surfaces of the traverse to the opposite inclined surfaces on the upper lower supports.
Denne udformning er vist på fig. 2, der viser apparatet ifølge opfindelsen i åben stilling - før fibrering - og fig. 3, der viser apparatet i lukket stilling - afslutning af fibre-ringen .This embodiment is shown in FIG. 2 showing the apparatus according to the invention in the open position - before fibrating - and fig. 3, showing the apparatus in the closed position - termination of the fiber ring.
Apparatet har en sokkel 41, der hviler på en bjælke 42 i en almindelig smedepresse; to slæder 43 0g 43', der hviler på styreflader 44 og 44' på sokkelen 41; en øvre travers 45, der er fast forbundet med en bevægelig travers 46 i pressen; to øvre sænkebærere 63 og 63', der bæres under traversen 45 af to donkrafte 64 og to donkrafte 64', der kan forskyde sig i forhold til traversen 45 parallelt med dennes skråflader 47 og 47' ved hjælp af to skråflader 65 og to skråflader 65'. Dette ophængningssystem kan også udformes på anden måde.The apparatus has a socket 41 resting on a beam 42 in a conventional forging press; two carriages 43 and 43 'resting on guide surfaces 44 and 44' on base 41; an upper traverse 45 fixedly attached to a movable traverse 46 in the press; two upper lowering carriers 63 and 63 'carried under the traverse 45 by two jack 64 and two jack 64' which can displace relative to the traverse 45 parallel to its sloping surfaces 47 and 47 'by two sloping surfaces 65 and two sloping surfaces 65 '. This suspension system can also be designed differently.

Nedenfor betegner: a) "apparatets øverste del" enheden A med de af fibro- matriceringsapparatets elementer, der er fastgjort til den øvre travers 45; b) "apparatets nederste del" enheden B med de af appa ratets elementer, der bæres af sokkelen 41; c) "lukket stilling" den stilling, alle apparatets ele menter indtager efter afslutning af fibromatrice-ringen; d) "åben stilling" apparatets og alle dets elementers stilling før fibrering med traversen 46 hævet maksimalt.Below: a) the "upper part of the apparatus" means the unit A with those of the elements of the fibrometer which are attached to the upper traverse 45; (b) the "lower part of the apparatus" means the unit B having the elements of the apparatus carried by the base 41; c) "closed position" means the position that all the elements of the apparatus occupy after the end of the fibromat ring; d) "open position" means the position of the apparatus and all of its elements prior to vibration with the traverse 46 raised maximum.
Før smedning står apparatet i åben stilling. De øvre sænke-bærere 63 og 63' er adskilt et stykke, svarende til stuk-ningsbevægelsen for en krumtaparm.Before forging, the appliance is in the open position. The upper lowering carriers 63 and 63 'are spaced apart, corresponding to the crank movement of a crank arm.
Sænkebærerne 63 og 63' kan forskyde sig i forhold til den øvre travers 45 parallelt med skråfladerne 47 og 47', hvilken symmetriske adskillelsesbevægelse for de to sænkebærere medfører en nedadgående bevægelse i forhold til traversen 45. Det er denne relative sænkning af de øvre sænke-bærere i dette øjeblik, som tillader - under fibromatrice-ringen - den relative sænkning af den øvre travers 45 i forhold til de øvre sænker 55 og 57 og bevirker således den symmetriske nærmelse af sænkerne til hinanden og dermed stukningen af krumtaparmene. Ikke viste indstillelige ansatser bestemmer i forhold til den øvre travers den nederste stilling af de øvre sænkebærere 63 og 63' og som følge heraf deres oprindelige afstand fra hinanden.The lowering supports 63 and 63 'can displace with respect to the upper traverse 45 parallel to the sloping surfaces 47 and 47', which symmetrical separation movement of the two lower carriers results in a downward movement relative to the traverse 45. It is this relative lowering of the upper lowering 45 carriers at this moment which allow - during the fibromatising ring - the relative lowering of the upper traverse 45 relative to the upper lowers 55 and 57, thus effecting the symmetrical proximity of the lowers to each other and thus the cranking of the crank arms. Adjustable positions not shown, in relation to the upper traverse, determine the lower position of the upper lower carriers 63 and 63 'and, as a result, their original distance from each other.
Donkraftene 64 og 64' trykker mod ansatserne ved begyndelsen af smedningen.The jacks 64 and 64 'press against the stakes at the beginning of the forging.
U6499 4U6499 4
Slæderne 43 og 43' adskilles også fra deres lukkestilling i samme udstrækning som de øvre sænkebærere 63 og 63', idet de ved afslutningen af deres bevægelse rammer nogle ikke viste ansatser på sokkelen 41.The carriages 43 and 43 'are also separated from their closing position to the same extent as the upper lower carriers 63 and 63', at the end of their movement hitting some not shown abutments on the base 41.
Under lukningen af apparatet hviler emnet 48 på de nedre sænker 34 og 36, traversen 46 sænkes, idet den medtager enheden A, indtil de øvre sænker 55 og 57 kommer til anlæg mod de nedre sænker 54 og 56 og fastklemmer emnet. De øvre sænkebærere 63 og 63' kommer samtidigt til anlæg mod slæderne 43 og 43', og en central sænke 50 kommer til anlæg mod en ambolt 51. Tværkiler 70 og 71 forhindrer enhver indbyrdes vandret bevægelse mellem henholdsvis slæderne 43 og 43' og sænkebærerne 63 og 63'. I denne startstilling for smedningen er donkraftene 64 og 64's tryk mod sænkebærerne 63 og 63' rigeligt stort til at forhindre de øvre sænker 55 og 57 i at løfte sig fra de nedre sænker 54 og 56. Den øvre travers 45 fortsætter sin nedadgående bevægelse fra det øjeblik, stukningen er igangsat, donkraftene 64 og 64' slækkes, og alene pressens lodrette tryk på skråfladerne sikrer de øvre sænkers anlæg mod de nedre sænker med et tryk, der er tilstrækkeligt til i ethvert øjeblik at modvirke de åbningskræfter, der udøves af det smedede metal. Fastkilingen mellem de øvre sænke-bærere 63 og 63' og slæderne 43 og 43' tilvejebringer med-bringningen af disse under stukningsbevægelsen. Resten af bevægelserne,omfattende forskydningen af krumtapbugten og afslutningen af fibromatriceringen, sker som beskrevet for det i franske patent nr. 994 026 med de to tilhørende tillægspatenter angivne apparat.During closure of the apparatus, the blank 48 rests on the lower recesses 34 and 36, the traverse 46 is lowered, including the unit A until the upper recesses 55 and 57 abut the lower recesses 54 and 56 and clamp the blank. The upper lower carriers 63 and 63 'simultaneously come into contact with the carriages 43 and 43', and a central lower 50 comes against a anvil 51. Crossers 70 and 71 prevent any horizontal movement between the carriages 43 and 43 'and the lower carriers 63 respectively. and 63 '. In this forging position, the pressure of the jack 64 and 64 against the lower supports 63 and 63 'is sufficiently large to prevent the upper lowers 55 and 57 from lifting from the lower lowers 54 and 56. The upper traverse 45 continues its downward movement from it. the moment the jamming is started, the jacks 64 and 64 'are extinguished, and only the vertical pressure of the press on the inclined surfaces ensures the abutment of the upper lowers with the pressure sufficient to counteract at any moment the opening forces exerted by the forged metal. The wedge between the upper lowering carriers 63 and 63 'and the carriages 43 and 43' provides for the carrying of these during the jamming movement. The remainder of the movements, including the displacement of the crank bay and the termination of the fibromatization, are carried out as described for the apparatus disclosed in French Patent No. 994 026 with the two appended patent.
Når fibromatriceringen er færdig, er apparatet "lukket".When the fibromatization is complete, the apparatus is "closed".
De øvre sænker 55 og 57 ligger an mod den centrale sænke 50 og de nedre sænker 54 og 56 mod ambolten 51. Derefter aktiveres donkraftene 64 og 64' til at trække sænkebærerne 63 og 63' opefter. Dette tjener til at blokere disse i anlæg mod sænken 50. Den bevægelige travers 46 hæves og medtager den øverste del af apparatet. De øvre sænkebærere 146499 5 63 og 63' frigøres fra slæderne 43 og 43' og de øvre sænker 55 og 57, og sænken 50 frigøres fra emnet 48.The upper lowers 55 and 57 abut the central lower 50 and the lower lowers 54 and 56 against the anvil 51. Thereafter, the jacks 64 and 64 'are activated to pull the lower supports 63 and 63' upwards. This serves to block these against abutment 50. The movable traverse 46 is raised and includes the upper portion of the apparatus. The upper lower carriers 14 and 63 'are released from the carriages 43 and 43' and the upper lowers 55 and 57, and the lower 50 is released from the workpiece 48.
Tilbage er da kun at trække emnet ud af apparatet, som, når sænkerne er adskilt, er klar til en ny smedningscyklus..The only thing left to do is pull the workpiece out of the appliance, which, when the counters are separated, is ready for a new forging cycle.
Den løftehøjde, der er nødvendig for at kunne trække den nederste del af apparatet ud fra pressen ved hjælp af spillet, er ved denne udførelsesform væsentlig mindre end den, der er nødvendig til gennemførelse af denne operation ved de i fransk patent nr. 994.026 omtalte apparater. Dette forhold tillader med den samme presse at anvende et apparat, der kan smede krumtaparme med større dimensioner end det er muligt med de konventionelle smedeapparater .In this embodiment, the lifting height necessary to be able to pull the lower part of the apparatus out of the press is substantially smaller than that required for carrying out this operation in the apparatus referred to in French Patent No. 994,026. . This ratio allows, with the same press, to use an apparatus capable of forging crank arms of larger dimensions than is possible with the conventional forging apparatus.
Fibromatriceringen kræver stukningskræfter, der er meget større end de, der er nødvendige til fri fibrering, og som kræver hjælpedonkrafte 58 med stort tryk, og pladsbehovet bliver derfor stort i dette tilfælde. Som vist på fig. 2 og 3 kan donkraftene 58 indmonteres i slæderne 43 eller 43'.The fibromatrication requires tensile forces much greater than those required for free fibrillation and requiring high pressure auxiliary forces 58, and the space requirement therefore becomes large in this case. As shown in FIG. 2 and 3, the jack 58 can be mounted in the carriages 43 or 43 '.
