Description

Fremgangsmåte ved fremstilling av stempelmaskin, Procedure in the manufacture of a stamp machine,

f.eks. forbrenningsmotor. e.g. internal combustion engine.

Som bekjent omfatter en forbrenningsmotor følgende hoveddeler: Sylinder av støpejern eller lettmetall med innpresset sylinderforing, veivhus rried veivaksel samt stempel med stempelstang. Sylinderen må alltid bearbeides nøyaktig for å settes fast på veivhuset, som vanligvis er todelt for innmontering av veivakselen. Det er her-under av den største betydning at sylinde-rens sentralakse kommer til å stå absolutt loddrett mot veivakslens sentralakse. Dette maskinbearbeidings- og monteringsarbeide må gjøres med den største nøyaktighet og blir av den grunn alltid kostbart. As you know, an internal combustion engine comprises the following main parts: Cylinder made of cast iron or light metal with a pressed-in cylinder liner, crankcase rried crankshaft and piston with piston rod. The cylinder must always be precisely machined to fit onto the crankcase, which is usually two-piece for fitting the crankshaft. It is of the greatest importance here that the central axis of the cylinder will be absolutely vertical to the central axis of the crankshaft. This machining and assembly work must be done with the utmost precision and is therefore always expensive.

Foreliggende oppfinnelse angår en fremgangsmåte ved fremstilling av en stempelmaskin, f. eks. en forbrenningsmotor, som gjør fremstillingen av motoren i høy grad enklere og billigere. Fremgangsmåten i henhold til oppfinnelsen kjenne-tegnes ved at sylinderen, (eller sylindrene) som støpes i ett stykke med veivhuset, støp-es om sylinderforing og rammelagerforinger som samtlige er bearbeidet på forhånd, hvoretter de bevegelige deler i motoren føres inn i sylinder og veivhus nedenfra idet veivarmen som er delt klemmes fast på veivakseldelene på hensiktsmessig måte etter at disse er ført inn gjennom rammelagerne. The present invention relates to a method for manufacturing a stamp machine, e.g. an internal combustion engine, which makes the manufacture of the engine much simpler and cheaper. The method according to the invention is characterized by the fact that the cylinder (or cylinders) which are cast in one piece with the crankcase, are cast around the cylinder liner and frame bearing liners, which have all been machined in advance, after which the moving parts in the engine are introduced into the cylinder and crankcase from below as the split crankcase is clamped onto the crankshaft parts in an appropriate manner after these have been fed in through the frame bearings.

På vedføyete tegning er det vist et eksempel dels på hoveddelen av en motor som er fremstillet ved fremgangsmåten i henhold til oppfinnelsen og dels en anord-ning for utførelse av støpe-fremgangsmåten i henhold til oppfinnelsen. Fig. 1 viser et lengdesnitt gjennom en ensylindret motor med de bevegelige deler montert inn. Fig. 2 viser liknende snitt gjennom samme motor, dreiet 90° i forhold til fig. 1. Fig. 3 viser i sideriss, delvis i snitt, kjerneverktøyet for støpningen av motoren. Fig. 4 viser samme verktøy sett dreiet 90° i forhold til fig 3. Fig. 5 viser et tverrsnitt etter linjen V—V i fig. 4. The attached drawing shows an example partly of the main part of an engine which has been produced by the method according to the invention and partly of a device for carrying out the casting method according to the invention. Fig. 1 shows a longitudinal section through a single-cylinder engine with the moving parts fitted inside. Fig. 2 shows a similar section through the same engine, rotated 90° in relation to fig. 1. Fig. 3 shows in side view, partly in section, the core tool for casting the engine. Fig. 4 shows the same tool rotated 90° in relation to Fig. 3. Fig. 5 shows a cross-section along the line V—V in Fig. 4.

Støpingen av motoren kan enten fore-tas etter tremodell i sand eller i stålkokille. The casting of the engine can either be done according to a wooden model in sand or in a steel mould.

Motoren i henhold til fig. 1 og 2 er tenkt støpt med det verktøy som er vist i fig. 3, 4 og 5, som kjerne. Delen 1 er en sylindrisk dor som er avpasset etter sylinderforingen 2. Delen 3 er montert sammen med doren 1. I delen 3 er det boret et hull med nødvendig passing for monterings-bolten 4. Videre gjør delen 5 i fig. 4 tjene-ste som kjerne for motorens avgasskanal. The engine according to fig. 1 and 2 are intended to be cast with the tool shown in fig. 3, 4 and 5, as core. Part 1 is a cylindrical mandrel that is adapted to the cylinder liner 2. Part 3 is mounted together with mandrel 1. In part 3, a hole is drilled with the necessary fit for the mounting bolt 4. Furthermore, part 5 in fig. 4 serves as the core for the engine's exhaust duct.

Sylinderforingen 2 og rammelagret 7 og 8 for veivakslen 6 samt kjernen 5 an-bringes på verktøyet i henhold til fig. 3 og legges inn i en sandform eller stålkokille, som ved støping gir motoren den utvendige form og godstykkelse som ønskes, slik som vist i fig. 1 og 2. Rammelagrene kan enten utgjøres av bronsebøssinger eller av stål-bøssinger, hvor det senere presses inn kule-lager. Etter at støpemetallene er størknet, trekkes bolten 4 i fig. 3 og kjernen 5 i fig. 4 ut. Derpå trekkes kjerneverktøyet i fig. The cylinder liner 2 and the frame bearing 7 and 8 for the crankshaft 6 and the core 5 are placed on the tool according to fig. 3 and is placed in a sand mold or steel mould, which, when cast, gives the motor the desired external shape and material thickness, as shown in fig. 1 and 2. The frame bearings can either consist of bronze bushings or steel bushings, where ball bearings are later pressed in. After the casting metals have solidified, the bolt 4 in fig. 3 and the core 5 in fig. 4 out. Then pull the core tool in fig.

3 ut. 3 out.

Etter denne operasjon er det oppnådd en motorsylinder med sylinderforing samt veivhus med rammelager, hvor samtlige deler inntar helt nøyaktig stilling i forhold til hverandre. After this operation, an engine cylinder with a cylinder liner and a crankcase with a frame bearing have been obtained, where all parts occupy a completely precise position in relation to each other.

Veivhuset er ikke delt men er åpent nedover for innmontering av de bevegelige hoveddeler av motoren. The crankcase is not divided but is open downwards for fitting the main moving parts of the engine.

Når åpningen i veivhuset er bearbeidet, blir stemplet 9 med veivstangen 10, hvis veivstangtapp 11 bærer to veivarmer 12 og 13, ført inn gjennom veivhuset. Deretter skyves veivakseltappene 6 inn i vedkommende rammelager 7 og 8 og føres inn i hull i vedkommende veivarmer 12 og 13. Disse veivarmer er hensiktsmessig delt med hver sin sliss 14, hvorved det blir mulig å spenne armene fast på vedkommende veiv-akseltapp 6, f. eks. ved hjelp av skruer 15. Det kan også tenkes annen fastlåsing enn ved hjelp av skruer. When the opening in the crankcase has been machined, the piston 9 with the crank rod 10, whose crank pin 11 carries two crank heaters 12 and 13, is brought in through the crankcase. The crankshaft journals 6 are then pushed into the respective frame bearings 7 and 8 and inserted into holes in the respective crank warmers 12 and 13. These crank warmers are suitably divided with each having its own slot 14, whereby it becomes possible to fasten the arms onto the relevant crankshaft journal 6, f e.g. by means of screws 15. It is also possible to think of other locking than by means of screws.

Fremgangsmåten i henhold til oppfinnelsen egner seg selvsagt også for støping av mere enn en sylinder sammen med veivhuset, og også for en motor med bare ett rammelager. The method according to the invention is of course also suitable for casting more than one cylinder together with the crankcase, and also for an engine with only one frame bearing.
