Guiding arm for wire bobbin winder.

[Detailed Description of the Invention]

The laying arm of a wire drum The present invention is a laying arm of the wire drum provided with roller guy 1 for a wire, and relates to the thing of the form currently formed with a plurality of forming rollers which curve formation of the roller guide concerned was carried out according to predetermined 3 order music victory, and are arranged at the above-mentioned wire drum. The laying arm which has the above-mentioned form is publicly known from the Federal Republic of Germany patent No. 2814143 specification. This laying arm has a forming roller of two rows, and connection arrangement of each of this roller of each other is carried out so that one guidance way for the wire which runs between both sequences within each sequence may be formed. However, this laying arm is expensive and the wear which is different according to that variously different load size will produce it on each roller again. The wire drum of the form stated to the beginning carries out laying arm Forget improvement of the subject of the present invention, and it is a thing exact by cost slight in comparison with little wear of which mechanism 7in wire system a' offer is done. This subject is solved by the means which was indicated in the 1st paragraph of the range of the claim according to the present invention and which it has feature 2, and the advantageous point by Lo present invention is that only rotation friction is formed by a small number of rollers. % and it is in it -- it is that of laying of the wire which exceeds still more publicly known Distraction wire thickness not on Kicking but on a thicker wire -- it is suitable for 8. In this case, it is possible to suit the load size and state of roller diameter 2 versatility. The thing of each roller to do for mutual interval Bi change regulation is also possible. in this case, especially an advantageous thing -- this interval -- the range of others [ the big range of the curvature of the 06th curve concerned ] -- also depending -- it is carrying out by small To < Si and it more nearly satisfactorily than guide The begging of this The. Since it is satisfactorily [ through Serra of a wire ] possible, according to the present invention, it is advantageous, if its distance is kept and it is arranged from the 6 order music victory concerned as the guide member for a wire is densely different on the roller between each roller at the that [ of the 6th above-mentioned curve ], and One side. Prevention of the splashes blank of a wire becomes more certain by this. A laying arm is formed for it being the same as the above as a pipe, and this pipe has Notch, A roller is few in that die surface 2 Or more respectively in this Notch (in this notch Within limits, attained also by being made to be engaged so that distance may be maintained from a wire or a pipe wall part on both sides of a roller.). It is this present invention about friction with a strong 70-pipe wall in which according to the embodiment of this laying arm it is simple, and is especially obtained in positive Lecture which met the object, and is rather used abundantly with the conventional device, therefore the laying pipe quickly worn out. It is also possible to exchange for the new laying arm boiled and depended. It is the perspective view of a laying arm in which two examples by the present invention are shown in the drawing, and Drawing 1 was formed as a pipe, The transverse cross section and Drawing 4 which Drawing 2 showed in the range of the laying A-Mobi roller with which the fragmentary longitudinal cross-section of the laying arm of Drawing 1 and Drawing 3 were formed as a pipe are a perspective view showing the laying arm by another example. In upper edge 2 which as for tubular laying arm 1 of the wire drum which is not illustrated was supported movably so that rotation to the wire drum was possible, The Distraction(ed) wire which carries out Running ON from a rolling passage is received, and by [ its ] carrying out A Miyoshi curvilinear passage, it fabricates to an endless ring wound strip, and Runaway this wound strip from lower end part 3 of arm 1. Eight forming rollers 4 continued and distributed to the full length as shown in Drawing 1 are allocated by laying arm 1 which has an inside diameter of 40 mm. An inside I b point interval of each of that roller is for 250 to 300 mm. In this case, the smallest interval is used in the maximum curvature range of the laying pipe concerned. within the limits of each roller 4 -- laying arm 1 -- the -- taking -- a side -- respectively -- one -- A shot of a beggar 5 and roller 4 is engaged by play in this Notch (- To (refer to Drawing 2 and the 6th figure).) In this case, wire fly cloudy weather-IQ= place by which laying should be carried out - It is a steel wire of the diameter of 1 and 22 Tomorrow. Since it is sealed, and is supported movably by 1 This ball bearing 7, this axis 6 inserts in this case, it is formed as an axis and it is being fixed by Nut 8 on axis 6, each roller 4 is easily exchangeable. This fixed mechanism is provided with hole 9 of one each of clamp 10 of V type which is twisted around laying arm 1 and is being fixed by welding joint 11, and is supported by the both sides of 1 Each leg. suitable [ in @6 ] at lubricous Is the center of ball bearing 7 -- it passes passage 2 and is carried out by grease nipple 12. Cooling of wire 13 adjoins roller 4 and a To blow off injection nozzle (not shown) performs a cooling medium according to a required grade in the movement direction of wire 13 in Notch 5. When wire 13 passes laying arm 1, it is supported only to roller 4 (refer to the 2nd figure). in this case, Tube division which forms a laying arm -- a maintenance of roller 4 sake -- work and Up -- it works simultaneously 1 This for positive cover of a wire, and guidance of a cooling medium by a case. According to the predetermined Miyoshi curve, curve formation is [ publicly known ] possible for this laying arm beforehand by the existing model. and Notch 5 is beforehand decided for roller 4 of laying arm 1, is formed in 1 Each place, and comes out after that -- clamp 10 for roller 4 is bound tight simply on Ah ' Beam. receiving curve altitude 14 or the axis-of-rotation line of roller 4 by next -- The -- positioning of the clamp 10 is performed by being made to be located perpendicularly (Drawing 3). The conditions that roller 4 is allocated in the place where the Miyoshi curve has the greatest curvature in the part of this The by this are fulfilled. Ball bearing 7 is loaded by this only in a radial direction, and a long life becomes possible by it. The number and size of low 24 are adjusted according to each load extent caused corresponding to the thickness and speed of a wire each time. As for laying arm IVcm, clamp 10 is touched after positioning. In being special, when it carries out as [ adjust / even afterwards / the position of each roller 4 ], it is the advantageous case of being alike, the long hole by which it was attached so that regulation on clamp 10 or laying arm 1 of this The was possible, and this was formed in clamp 10 -- penetrating two times -- a lei -- a globefish -- it may be simply performed by at least one attachment screw displaced within arm 1. comprise pipe 15 with which laying arm 1' was straightly prolonged in another example shown in Drawing 4, and upper end part 2' of this pipe 15 is combined so that a wire drum and rotation are possible -- a leg -- a plurality of arms 16 in which length regulation is possible are attached to pipe 15 so that revolution is possible. Clamp 10' of V type which Kaoru holding roller 4 is allocated in the free end section of each arm 16. This clamp 10' is combined with arm 16 via ball joint 17, and roller 4 can be adjusted in all the arbitrary directions by this. Regulation formation of the 3 order music victory of a request is first carried out by suitable revolution of each arm 16, height, and length regulation. In this case, at the time of a laying start, about a wire, satisfactorily, since it is possible, it is [ a through set and ] advantageously, If the 5th curve concerned takes between each roller 4 and a direction board is arranged to a side (its distance is kept and this direction board is arranged from the 3rd above-mentioned curve in a precedent so that the outside tube-like portion of laying arm 1 may be so, and each roller may be reached densely.) This direction board is attached to clamp 10', and works simultaneously also for position fixation of laying arm 1'. The advantageous point of the example of Drawing 4 is that conformity formation is easily possible on the 6th curve that is different in various laying arms. International tone Loss
