CLASS IN NTERNATIONAL SWEDISH B 21 d7 c: 4/02 PATENT AND REGISTRATION AGENCY Ans. 4778 1959 on 2015 1959Harlin en drawing AB GOTAVERKEN, GOTEBORG Machine for producing corrugated, bent or otherwise designed building elements from flat materials TJppfinnare: NV Svensson and BNA Svenson stone units of coarse material, as there may be tal am at shots in ships, the very handling of the amnet in the machine involved certain responsibilities.

Foreliggande uppfinning avser en med ett fast bord och en mot och frail detta rorlig 15- pare forsedd maskin avsedd att av plana amnen framstalla korrugerade, bockade eller pa annat satt utformade byggnadselement, foretr5desvis delar av skott till fartyg, vid vilken maskin bordet resp. loparen, vardera är for-sett med en kring sin langdaxel vridbar, valsformad verktygshallare uppbarande en uppsattning verktyg omfattande ,stampel och dyna. The present invention relates to a machine equipped with a fixed table and a movable 15-pair machine intended to produce corrugated, bent or otherwise designed building elements from planar blanks, preferably parts of bulkheads for ships, at which machine the table resp. the runner, each is provided with a, roll-shaped tool holder rotatable about its long axis, carrying a set of tools comprising, piston and pad.

Maskiner som astadkomma de 8nskade ombockningar i materialet utan att detta be-hover vandas flera ganger under bearbetningsproceduren are tidigare kanda. Vid dylika maskiner aro bockningsyerktygen utformade direkt i en grey cylinder som relativt sin infastning är vridhar, sa -att, maskinen kan Andras genom en enkel omstallning. Dynan anordnas dt vid ett tillfalle i nedre och vid nasta arbetsoperation i den Ovre cylindern, varvid samtidigt stampeln pa motsvarande satt byter plats. Machines which produce the desired bends in the material without the need to be used several times during the machining procedure are previously known. In such machines, the bending tools are designed directly in a gray cylinder which, relative to its attachment, is rotatable, so that the machine can be changed by a simple adjustment. The pad is arranged there in a case in the lower and in the next working operation in the upper cylinder, whereby at the same time the piston in a corresponding manner changes place.

Om nu bockningsverktygen aro utformade direkt i eylindern, har man ingen m5jlighet att ta hansyn till forslitning eller byte av verktyg som betingas av olika onskad form hos arbetstycket. Uppfinningens andamal Or att med bibehallande av tillfredsstallande upplagring av bockningsverktygen astadkomma en maskin som undviker de ovannamnda olagenheterna helt och hallet darigenom att vardera verktygshallarens tvarsnittsyta begransas ,av en vasentligen 180° av cankretsen tackande eirkelbage s‘amt av tva. 90' mot var andra staende kordor inom gamma cirkelbaglinjes forlangning, och att mot kordorna svarande plan i vardera hallaren aro utformade som fasten for som utbytbara enheter utforda verktyg. If the bending tools are now designed directly in the cylinder, it is not possible to take into account the wear or replacement of tools which are conditioned by different desired shape of the workpiece. The object of the invention is to, while maintaining a satisfactory storage of the bending tools, provide a machine which completely avoids the above-mentioned imperfections by limiting the cross-sectional area of each tool holder by a substantially 180 ° of the cancerous circle or two. 90 'to each other standing cords within the length of the gamma circular backline, and to the planes corresponding to the cords in each hall are designed as fasteners for as interchangeable units to challenge tools.

A bifogade ritning visas sasom exempel schematiskt uppfinningen sadan den tillampas yid en maskin far bockning av skottplatar till fartyg, varvid amnet bearbetas pa sadant satt, att korrugeringar i form av halva sexhorningar erhalles. Figur 1 visar ett snitt genom den verksamma delen av maskinen enligt uppfinningen, varvid det nedre verktyget Si verksamt som stampel och det iivre som dyna. Figur 2 visar samma snitt, men med verktygen omstallda 90°, sa att denna gang det nedre verktyget Or verksamt so-rn dyna och det ovre som stampel. The accompanying drawing schematically shows the invention as an example so that it is applied to a machine for bending bulkheads to ships, the workpiece being processed in such a way that corrugations in the form of half hexagons are obtained. Figure 1 shows a section through the active part of the machine according to the invention, the lower tool Si acting as a punch and the upper one as a pad. Figure 2 shows the same section, but with the tools turned 90 °, so that this time the lower tool is effective as a pad and the upper as a punch.

Maskinen kan Tara av godtyckligt I och for sig kant slag, t. ex. med ett fast undre ho-rd och en ovre lapare, som är rorlig fran och mot detta. En. sadan lopare styres i gejder utriled sina andkanter och paverkas vanligen hydrauliskt. I det har aktuella fallet, dar maskinen Sr avsedd far bearbetningskott- platar till f artyg kan oppningen och alltsa verktygets Iangd vara 15 -meter eller mer. Saclan plat liar dessutom avsevard tjocklek, och det blir darfor fraga om myeket stora krafter. Bordet ,anordnas lampligen under och loparen ovanfor oppningen, men det Or naturligtvis inget som hindrar att det omvanda forhallandet kan intraffa. Dessa huvuddelar, som lake ha nagot direkt inflytande pa sjalva uppfinningen ha lake visats, utan de kmma som sagt utforas pa godtyckligt i och for sig kant salt. Pa ritningen betecknar 1 det fasta bordet och 2 den mot och Iran detta rorliga loparen. I var och en av dessa delar ar monterad en verktygshallare 3 rasp. 4 i form av en cylinder, vilka var och en uppbara en uppsattning verktyg, som aro 1511 utbytbara I Or astadkomman- 2— — de av olika utseende pa korrugeringen. Verktygshallaren 3 resp. 4 är vridbart monterad i sin infastning -vid bordet resp. loparen. Utmed ungefar halften av cylinderns omkrets aro verktyg i form av stampel 11 och dyna 9 anbragta i 900 iabordes vinkel. Dessa verktyg stracka sig Over hela cylinderns nyttiga langd. Dynan 9 ar utformad som ett rannforrnat stycke, och kan yarn forsett med ett utbytbart mothall 10, genom vilket det ar mojligt att hegransa djupet pa bockningen. Stampeln 11 ar oeksa sa utford att den latt kan bytas och dr farsedd med en speciell toppdel 12, som kan ersattas. Den andra halften av resp. cylinderns omkrets dr ograverad och ligger i en efter cylinderdiametern a-vpassad ra.nnformad urtagning i bordet rasp. loparen sa att cylindern stodes utefter hela sin langd. Genom en omstallning av cylindern i 900 kan salunda vilket corn heist av verktygen bringas I verksaint ldge, varvid samtidigt den diametralt motsatta ytan i cylindern anligger mot sitt stod. Man gar vid bearbetningen ut frail ett planat amne och eftersom dynan antingen ãr verksam i overcylindern och stampeln i undereylindern eller amvant kan amnet under hela bearbetningsproceduren foras utan -vandningar genom maskinen. The machine can Tara of any per se edge type, e.g. with a fixed lower ho-rd and an upper lapar, which is movable from and towards this. One. such runners are guided in guides out of their duck edges and are usually hydraulically actuated. In the present case, where the machine is intended for machining cutting plates for vessels, the opening and thus the length of the tool can be 15 meters or more. Saclan plat also has a considerable thickness, and it is therefore a question of very large forces. The table, is suitably arranged below and the runner above the opening, but this Of course there is nothing to prevent the converted relationship from occurring. These main parts, which have had a direct influence on the invention itself, have been shown, but the ones which are said to be carried out on arbitrarily per se edge salt. In the drawing, 1 denotes the fixed table and 2 the counter and Iran this movable runner. A tool holder 3 rasp is mounted in each of these parts. 4 in the form of a cylinder, each of which carries a set of tools which are 1511 interchangeable in order to provide the different appearance of the corrugation. Tool holder 3 resp. 4 is rotatably mounted in its mounting - at the table resp. loparen. Along about half of the circumference of the cylinder are tools in the form of a punch 11 and a pad 9 arranged at an angle of 900 degrees. These tools extend over the entire useful length of the cylinder. The pad 9 is designed as a flow-shaped piece, and can be provided with a replaceable counter stop 10, through which it is possible to examine the depth of the bend. The piston 11 is so challenged that it can be easily replaced and fitted with a special top part 12, which can be replaced. The other half of resp. the circumference of the cylinder is unengraved and lies in a groove-shaped recess in the table which is adapted to the cylinder diameter. the runner said that the cylinder stood along its entire length. By a rearrangement of the cylinder in 900, the corn heist of the tools can be brought into operation, whereby at the same time the diametrically opposite surface of the cylinder abuts against its stand. During machining, a flat workpiece is removed and since the pad is either active in the upper cylinder and the piston in the lower cylinder or amvan, the workpiece can be passed through the machine without irrigation during the entire machining procedure.
