JPS5913517A - Treatment of tail end of wire rod - Google Patents

Abstract

PURPOSE:To eliminate the need of special fixing means, by reduction rolling the tail end of a wire rod to make it have the radius of curvature smaller than the coiling radius, and allowing the wire rod to coil around a spool, etc. by means of its coiling nature caused by the rolling. CONSTITUTION:The tail end 14a of a wire rod 14, to be coiled by a spool 12 or on the coiled wire rod, is reduction rolled to give a coiling nature to the tail end 14a by passing it through a group 16 of rolling rolls and a group 18 of feeding rolls. The tail end 14a is formed to have the radius of curvature smaller than the radius of coiling. Thus the tail end 14b of the rolled wire rod 14 coils around the spool 12 or around the wire rod coiled already because of the rigidity of the work-hardened tail end 14b, and that eliminates the need of special fixing means.

Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a method for processing the end of a wire rod to be wound in a thin winding manner, and in particular, the starting end of the wire rod is placed on a spool with #4y,
Bamboo also relates to a method of attaching a winding terminal to a winding line trunk.

It is necessary to attach the wire rod to be wound on the wire winding machine to the spool at the beginning and end of the wire, and to attach the end of the wire onto the wire that has already been wound. In the case of a thin wire body with a diameter of 5 to 1.0 mm, the ends of the wire rods were held in place by tacking them with adhesive tape, such as Bell I & However, with this method of attaching wire ends using adhesive tape, the work is cumbersome as the adhesive tape, which has been cut by an inch, must be peeled off when the wire rod is fed from the wire rod roll to the 7th wire rod process. There is a risk that the part on which this adhesive tape is pasted will become dirty, and if there is moisture on the surface of the wire, the adhesive tape will fail to attach, and if left for a long time, the connection will be damaged. The problem was that the layer tape would peel off. Furthermore, if the wire rod has strong rigidity, it is difficult to suppress it with adhesive tape, and it is necessary to use special fixing means.

The object of the invention is to provide a wire end treatment method that can easily and reliably suppress even a highly rigid wire without using any special fixing means! i! The purpose is to provide two meetings.

The detailed description will be made with reference to all the drawings showing the implementation steps of the present invention.
4 shows a method of processing the end-of-volume terminal 14a of Volume 4 in an inventive manner. After winding all the wire feathers 14 on the spool 12, the winding end end 14a'z is grasped and passed to the processing roller group 16 and the second feeding row group 18. The processing roller group 16 includes a movable roller 22 that moves forward and backward by a cylinder 20, and fixed rollers 24, 24' that sandwich the end winding end 14a and f by the advancement of this oJ cutting roller.
The movable roller 22 is moved forward and backward by a cylinder. In addition, the feeding roller group 18
consists of a fixed roller 28 and a roller 30, and the movable roller 30 is moved forward and backward by a cylinder 32.When passing the winding end 14ai through the processing roller group 16 and the feeding roller group 18, The movable rollers 22, 30' (z
Dotted line position in Figure 1 [itl'il: Retreat, Volume P:
After the terminal 14a has passed through the feeding roller group 18-i, the moving rollers 22 and 30 are advanced to the solid line position in FIG.
In this way, after passing the winding end 148 of the spool 14 through the processing roller group 16 and the feeding roller group 18, the spool 12 is moved in the winding direction. The fixed roller 24 of the processing roller group rotates to
, 24' and the fixed roller 28 of the feeding roller group are rotated in the direction of the arrow, and the winding end 14a is subjected to surface reduction processing by the force roller group 16 while smoothing out the curves.

Figure 2 shows the winding end 14 which has been subjected to surface reduction processing in this way.
The side of b is 1t; I'l is shown. The winding end 14a is provided with a radius of curvature smaller than the winding radius Ro. This radius of curvature can be adjusted by fully adjusting the distance between the fixed rollers 24.degree. 24' (the distance between the Ell flora 22 in the circumferential direction). Therefore, the volume ending terminal 14
When a exits through these roller groups 16 and 18,
The radius of curvature is smaller than the winding radius R8, and since it is work hardened and given rigidity by surface reduction processing, it will not be unraveled by winding around the wire rod 14 wound on the school 12 due to its own oil impregnation. .

Note that the linear speed of the rollers 24, 24', and 30 is 2
The speed should be slow, about m/min. 'l: Linear speed due to school 12 is roller 24, 24', 30
The linear velocity is approximately 90X. The reason is that the curved line created by processing roller #16 is pulled by school 12 and becomes straight. This is to prevent this.

'i7ζ, in the first row, reference numeral 34 is a looper that absorbs the sagging sound of the transmission and synchronizes the school 12 and the rollers f4f' 16 and 18 to 4.

On the above-mentioned side, the process for the end of the volume is described, but it is also possible to process the beginning of the volume in the same way. Additionally, the feeding roller group 18 is necessary when the wire 114 is thick, but may be omitted when the wire 14 is thin.

According to the non-inventive method, as mentioned above, since the wire end is subjected to surface reduction processing so as to have a radius of curvature smaller than the winding radius, the wire end is bent on the wire or has already formed on the wire.
The line 4"l' is placed on top of the inserted wire so that the wire ends can be reliably tightened without the need for any special fixing means, and the trench can be secured.
In addition, it is easy to unroll the legs in the next step, and there is no fixing means on the acid phase surface, making it easy to transport.Moreover, the ends of the legs may unravel during transportation, further contaminating the scraping. This makes handling easier.
