Description

-1 - DK 171035 B1-1 - DK 171035 B1

Opfindelsen angår en slibeindretning ifølge indledningen til krav 1, således som den fx. er vist i DE-offentliggørelsesskrift 30 36 490.The invention relates to a grinding device according to the preamble of claim 1, such as for example. is disclosed in DE publication publication 30 36 490.

Ved den kendte udformning bestod opgaven i at føre slibeskiven i en enkelt indstilling hen til de til slibning bestemte flader på snittekniven og at s overlade den yderligere indstilling af slibeskiven til en fjeder. Til dette formål behøves en stærk fjeder. For at føre slibeskiven efter slibningen til hvilestillingen, skal kraften fra fjederen overvindes over en forholdsvis lang vej ved hjælp af en håndbetjent skruespindel.In the known design, the task consisted in guiding the grinding wheel in a single setting to the surfaces for grinding the cutter and thus leaving the further adjustment of the grinding wheel to a spring. For this purpose a strong spring is needed. In order to guide the grinding wheel after grinding to the rest position, the force of the spring must be overcome over a relatively long way by means of a hand operated screw spindle.

Opfindelsen har til hensigt at forenkle og lette tilbageføringen af slibe-io skiven efter slibningen. Til dette formål skal der anvendes en forspændt og i sin fjedring begrænset fjeder, hvis fjederstrækning kun er tilstrækkelig til at udvirke efterindstillingen af slibeskiven, medens den strækning, som er nødvendig for at bringe slibeskiven til hvilestilling, ikke skal gennemløbes mod fjederkraften.The invention intends to simplify and facilitate the return of the abrasive to the disc after the abrasive. For this purpose, a pre-tensioned and limited spring must be used, the spring stretch of which is only sufficient to effect the resetting of the grinding wheel, while the distance necessary to bring the grinding wheel to a rest position must not be passed against the spring force.

is Ifølge opfindelsen foreslås det til dette formål, at fjederen dels støtter sig mod en med den længdeforskydelige akse fast forbundet planflade og dels mod en med gevindbolten fast forbundet plan flade, hvor der på gevindbolten er anbragt et anslag, som begrænser udslaget af fjederen i forhold til lasken.In accordance with the invention, it is proposed for this purpose that the spring is partly supported on a plane surface fixedly connected to the longitudinal axis and partly against a flat plane fixedly connected to the threaded bolt, where a stop is arranged on the threaded bolt which limits the impact of the spring in relation to the to the bottle.

Ved en hensigtsmæssig udformning rækker gevindbolten gennem den ao med den længdeforskydelige akse fast forbundne planflade, som atter er aksialt forskydelig på gevindbolten mellem to anslagsflader. Yderligere ejendommeligheder ved opfindelsen fremgår af de afhængige krav 3 og 4.In a suitable design, the threaded bolt extends through the ao with the longitudinally displaceable axis flat surface, which is again axially displaceable on the threaded bolt between two abutment surfaces. Further features of the invention are apparent from the dependent claims 3 and 4.

Et udførelseseksempel forklares ved hjælp af tegningen.An exemplary embodiment is explained by means of the drawing.

En snitteskive 1, som roterer i et snittehus 2 med sidevægge 3, er forsynet 2s med knive 4, som samvirker med en ikke vist modkniv.A cutting disc 1, which rotates in a cutting housing 2 with side walls 3, is provided 2s with knives 4 which cooperate with a counter knife not shown.

På en konsol 5, som er fast forbundet med en sidevæg 3, står et lejehus 6, som har en i forhold til snitteskiven 1 akseparallel boring 7. I denne boring er en akse 8 lejret længdeforskydeligt. På denne akse er der på den ene side drejeligt lejret en slibeskive 9 ved hjælp af to kuglelejer 10. Med den anden ende af ao aksen 8 er der fast forbundet en laske 11, som har en planflade 12 og en boring 13.On a bracket 5, which is firmly connected to a side wall 3, stands a bearing housing 6 which has an axis parallel to the cutter disc 1 in this bore. In this bore, an axis 8 is mounted longitudinally displaceable. On this axis, on one side, a grinding wheel 9 is rotatably mounted by means of two ball bearings 10. With the other end of the axis 8 there is firmly connected a groove 11, which has a flat surface 12 and a bore 13.

En gevindbolt 14 rækker gennem boringen 13, der er lejret drejeligt og dermed længdeforskydeligt i et gevind i et fremspring 15 på lejehuset 6. Fremspringet 15 er på sin frie ende 16 slidset op og kan spændes ved hjælp af en 35 knebelskrue 17. Med gevindbolten 14 er der forbundet et håndsving 18, som på en mod fremspringet 15 vendende side har en planflade 19. En skive 20 støtter sig mod planfladen 19, og en yderligere skive 21 mod en stift 22, som går gen- - 2 - DK 171035 B1 nem gevindbolten 14. Mellem skiven 20 og planfladen 12 er der indlagt en af tallerkenfjedre dannet, forspændt fjederpakke 23.A threaded bolt 14 extends through the bore 13 which is pivotally mounted and thus longitudinally displaceable in a thread in a projection 15 of the bearing housing 6. The projection 15 is slit open at its free end 16 and can be tightened by means of a threaded screw 17. With the threaded bolt 14 there is connected a crank 18 which, on a side facing the projection 15, has a flat face 19. A washer 20 supports against the flat surface 19, and a further washer 21 against a pin 22 which extends easily. the threaded bolt 14. Between the washer 20 and the flat surface 12 is inserted one of plate springs formed, biased spring package 23.

I hvilestillingen er slibeindretningen rykket så meget tilbage, at endefladen af slibeskiven 9 omtrent befinder sig på højde med indersiden af sidevæg-5 gen 3. For at bringe slibeindretningen i arbejdsstilling løsnes knebelskruen 17, og gevindbolten 14 forskydes ved hjælp af håndsvinget 18 så meget, at den på den længdeforskydelige akse 8 lejrede slibeskive 9 med sin endeflade berører den til slibning bestemte kniv 4. Gevindbolten 14 drejes herpå yderligere så meget, at det svarer til den ønskede afslibning af kniven 4. Fjederen 23 spændes to først med denne størrelse, hvorhos skiven 21 løfter sig fra stiften 22. Med fremadskridende afslibning mindskes spændingen af fjederpakken 23 atter, indtil mellemlægsskiven 21 ligger an mod stiften 22. Slibningen er hermed afsluttet, og slibeskiven 9 kan med håndsvinget 18 drejes tilbage uden kraftudfoldelse til hvilestillingen.In the resting position, the grinding device is retracted so much that the end surface of the grinding wheel 9 is approximately at the level of the inside of the side wall 5. To bring the grinding device into working position, the screw screw 17 is loosened and the threaded bolt 14 is displaced by the hand crank 18 that the abrasive disc 9 mounted on the longitudinally displaceable axis 8 with its end surface touches the knife 4 for grinding 4. The threaded bolt 14 is then further rotated so that it corresponds to the desired grinding of the knife 4. The spring 23 is first tensioned two with this size, the disc 21 lifts from the pin 22. With progressive abrasion, the tension of the spring package 23 is reduced again until the intermediate disc 21 abuts the pin 22. The abrasion is hereby terminated and the abrasive disc 9 can be turned back by the crank 18 without force exertion to the rest position.
