Description
4§1 446 Profilen 1 insätts i anordningen, i fig. 1, så att profilens ände förs in genom griporganet 3 och läsorganet 5 fram till punkten mellan stämpeln 8 och dynan 9. När man nu lyfter stämpeln 8 uppåt med hjälp av den hydrauliska cylindern 6 såsom angives genom pilen 12, böjs profilens ände ett böjningssteg. Stämpeln 8 àterförs till nedre läget och med hydrauliska matningscylindern 2 matas profilen fram ett steg, varefter nästa böjning företas med böjcylindern 6. Medan böjning pågår kläms profilen fast av làsorganet 5. Härmed formas profilen till en cirkelformig krans ett steg i taget. Om man ytterligare brukar det till anord- ningen hörande stigningsbordet 10, som likaså böjer profilen till stigning ett steg i taget, erhåller man en skruv. För exempelvis grustransport behövs en transportskruv, som har gjorts av tillräckligt tjockt material och är tillräckligt styv,i eftersom materialet som transporteras är tungt och sliter skruven. 4§1 446 The profile 1 is inserted in the device, in Fig. 1, so that the end of the profile is inserted through the gripping means 3 and the reading means 5 up to the point between the piston 8 and the pad 9. When the piston 8 is now lifted upwards by means of the hydraulic cylinder 6 as indicated by the arrow 12, the end of the profile is bent one bending step. The piston 8 is returned to the lower position and with the hydraulic feed cylinder 2 the profile is fed one step, after which the next bending is performed with the bending cylinder 6. While bending is in progress, the profile is clamped by the locking member 5. This forms the profile into a circular ring one step at a time. If you further use the pitch table 10 belonging to the device, which also bends the profile to pitch one step at a time, a screw is obtained. For gravel transport, for example, a transport screw is needed, which has been made of sufficiently thick material and is sufficiently rigid, since the material being transported is heavy and wears the screw.
Det är klart för en fackman i branschen att uppfinningens olika utföringsformer kan variera inom ramen för de efterföljande patentkraven.It will be apparent to one skilled in the art that the various embodiments of the invention may vary within the scope of the appended claims.
Sålunda kan längden ælsteget som pà en gång böjs variera, men den är lämpligast endast några få grader, t.ex. 2-HO. »afThus, the length of the electric step which is bent at once can vary, but it is most suitable only a few degrees, e.g. 2-HO. »Af
