方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a welding wire winding spool (hereinafter abbreviated as a cage spool) for winding a welding wire in a cage shape with double flanges formed by combining metal wire rods. It relates to a method for processing the winding start end of welding wire (hereinafter referred to as wire) into a locking structure, in particular, a method that allows the wire to be easily and reliably locked to the winding drum of a car spool, and which is further formed by cutting the wire. Using a sharp cutting edge, a locking structure that does not cause cuts or the like to the outer peripheral surface of the winding drum or the winding wire itself during wire locking or subsequent wire winding is easily fabricated. The present invention relates to a method for processing the starting end of a welding wire winding.

されている。[Prior Art] A cage spool is a spool element a, which is formed by bending a single metal wire (usually a steel wire) 1, as shown in FIG. A plurality of b, c... are arranged in a circular shape,
The radial rims of adjacent spool elements are joined together to form a spool with both flanges, and it is inexpensive, lightweight, and has sufficient strength.
Furthermore, it has the advantage of being easy to recover as a metal resource after use, so its use is expanding as an alternative to conventional wooden spools and plastic spools. The surface of this spool is coated with a rust-preventing insulating coating from the viewpoint of rust prevention and insulation.

に係止しておかなければならない。 By the way, when winding wire around a car spool, the wire winding start end must be locked to the winding drum, but if the wire winding start end is not fully locked and the wire is wound, During use, when the remaining amount of wire winding becomes small, the winding start end tends to come off, and the winding wires become entangled with each other due to springback etc., increasing the pull-out resistance, or the end of the wire that comes off may become attached to the base material. There is also a risk of injury due to contact with. Therefore, the starting end of the wire winding must be securely locked onto the spool.

It is not possible to repurpose the method (such as a method for latching a car spool) as it is, but it is necessary to devise a unique latching structure that takes into account the unique structure of the car spool. Furthermore, the leading edge of the wire has a sharp edge that has been cut with a knife, cutter, etc., and the work is complicated, so grinding (polishing) of the edge is not performed. If the edge comes into strong contact with the spool winding drum during locking, there is a problem that the rust-proof insulation coating on the surface of the winding drum will be torn and lose its insulation properties, causing the wire to shoot. If the wire comes into strong contact with its own outer peripheral surface, the copper plating will be damaged and the wire will rust.

At the same time, by bending the leading end of the wire constituting the hook part again in the same plane as the U-turn and in a direction away from the slit groove, a bent part is formed on the leading end side. The gist of this method is to extract the processed winding start end from the slit.

下して使用時に「シヨート」を起す。 The first possible locking structure for the wire winding start end that is locked to the winding trunk wire of the car spool is as follows.
For example, as shown in FIGS. 3 and 4, the tip of the wire W is bent into a hook shape and locked. That is, the third
In the figure, the tip of the wire W is bent from the inside of the winding drum constituting wire 2 to the outer circumferential side of the winding loop to be locked to the winding drum constituting wire 2. However, in such a locking structure, spring back etc. There is a problem in that when a force in the direction of arrow A is applied, the locking portion easily comes off from the wire rod 2 constituting the winding drum. Moreover, the sharp edge part Wp of the wire W may protrude to the outer circumference of the winding loop, but in that case, the edge part Wp will strongly contact the surface of the next layer winding wire W2 , damaging the copper plating layer. This will cause the wire to rust. Fig. 4 also shows that the tip of the wire W is bent toward the center of the winding drum to form a substantially triangular loop along the cast. Part) Wp and loop start point
In addition to setting the narrowest winding drum component wire passing gap A between Ws and Ws, consideration has been given so that the entrance angle α of the loop end point Wp to the loop start point Ws is an acute angle.
The tip of the wire can be easily locked to the wire rod 2, and once locked, it will not easily come off. That is, if the passage gap A is made smaller than the diameter of the wire rod 2 constituting the winding drum, the wire rod 2 is pushed from outside the passage gap A to the inside of the loop at the time of locking (or the entire wire W is pushed to the left in the figure). (pulling in the direction), the loop end side Wb of the wire W is elastically deformed and displaced as shown by the chain line in the figure, and the gap A widens accordingly, and the winding drum constituent wire 2 enters into the loop. . Then, the loop end side Wb released from the pushing force by the wire rod 2 returns to its original state, narrows the passage gap A, and prevents the wire rod 2 from coming off. This locking method has already been patented by the applicant (Japanese Patent Application No. 58-53019), and is excellent in terms of ease of locking the start end of the wire winding and prevention of separation. However, in this locking structure, the outer peripheral surface of the wire rod 2 constituting the winding drum is the loop end point.
As the Wp enters and locks into the loop by being rubbed against the sharp edges of the wire, the anti-rust insulation coating on the surface of the wire is damaged, and the insulation of the winding trunk is reduced, resulting in " Wake up "Shyoto".
そこで本発明は、この様な防錆絶縁被覆の損傷

得るものである。 Therefore, the present invention can be fabricated into a locking structure for the starting end of a wire winding, which can solve the problem of "short circuit" caused by damage to the rust-proof insulation coating.

つき損傷」という問題を生ずる余地もない。 FIG. 5 is an explanatory diagram showing a typical example of a locking structure processed and formed according to the present invention. That is, FIG. 5 is an explanatory diagram illustrating a locking structure that achieves the above object. Basically, the tip of the wire W is bent into a hook shape toward the winding center direction, and the wire W is wound in the same manner as the example shown in FIG. A locking portion is constituted by a non-closed loop-shaped hook portion that leaves a passage gap A for the body-constituting wire 2. Then, the leading end Wp of the wire W passes through the narrowest part constituting the passing gap A, and an S-shaped bent part is extended in a direction away from the passing gap A. That is, the tip of the wire that constitutes the opening wall H on one side of the narrowest part is formed by the gently curved back surface of the wire itself, and the sharp wire edge Wp is retracted to a position where it does not come into contact with the wire 2 forming the winding drum. . Therefore, in the locking step performed in the same manner as shown in FIG.
The opening wall H formed by a gentle curve only comes into contact with the outer circumferential surface of the wire rod 2 constituting the winding drum, and there is no possibility that the wire rod 2 will come into contact with or be rubbed by the edge portion Wp. As a result, the rust-proof insulating coating on the surface of the wire rod 2 is not damaged, and it is possible to reliably prevent problems with shoots caused by damage to the coating on the winding trunk. Moreover, the leading edge Wp of the wire is retracted and extended in the axial direction of the wound wire, and is not exposed to the outer periphery of the initial layer of the wound wire. There is no possibility of causing the problem of "damage due to copper plating on the surface of the layer-wound wire."

脱を防止する構造とするものでも構わない。 In this way, the opening wall H on one side constituting the passage gap A of the wire rod 2 constituting the winding drum is constituted by the gently curved back surface of the wire W itself, and the edge portion Wp is retracted from the passage gap A. Other locking structures are also possible as long as they have these features. For example, Fig. 6 shows the wire with the leading end Wp retracted to the inside of the loop, Figs. 7 and 8 show the loop-shaped hook part formed into a substantially perfect circle, and Fig. 9 shows the above-mentioned hook part. It is shown that it is formed into a substantially rectangular shape. Furthermore, FIG. 10 is an example in which the entrance angle α explained in FIG. Such a locking structure is also possible because the portion serves as a pushing guide for the wire rod 2 constituting the winding drum and functions to guide the wire rod constituting the winding drum 2 in the direction of the passage gap A. Furthermore, in the above-mentioned examples, the winding drum constituting wire 2
A structure in which the passing gap A is made narrower than the outer diameter of the wire 2 from the beginning and the gap A is forcefully widened and locked using the elasticity of the wire W has been shown.
In addition, the passage gap A may be made wider than the outer diameter of the wire 2. In this case, after the wire 2 is engaged, the loop is pushed from the outer circumferential side by appropriate means in a direction to narrow the passage gap A. The structure may be such that the wire rod 2 is deformed to prevent the wire rod 2 from coming off.

たものにすぎない。 An example in which the present invention is applied to a method of processing the welding wire winding start end of the locking structure described above will be described in detail below. In this example, the case of processing into the locking structure shown in FIG. 5 will be exemplified.
The locking structure shown in the figure can also be processed in the same manner as in this example. First, FIG. 11 shows that due to the rotation of the wire feeding roller 5 (and the rotation of the spool itself),
This diagram schematically shows a state in which a predetermined amount of wire W has been wound around a spool, and the wire tip processing device 6 is installed in front of the feeding roller 5, and is retracted toward the back side of the page when winding the wire. . This tip processing device 6 includes a support member 8, a first bending member 9, and a second bending member 9.
It is composed of a set of bending members 10, and the support member 8 has a tongue-like protrusion 11 for forming a locking loop and a recess 12 for forming a passage gap A at its lower end, as shown in FIG. A convex portion 13 for retraction of the leading edge Wp of the wire is formed, and a slit groove 15 in the shape of a horizontal groove is formed passing through these convex portions. Further, the first bending member 9 is disposed so as to be movable in an oblique direction (direction intersecting the longitudinal direction of the slit groove 15) along the left-hand inclined surface 11a of the tongue-like convex portion 11 in the figure, and the second bending member 10 has a tip shape that meshes with the recess 12 for forming the passage gap A, and is arranged so as to be movable in the direction of the recess 12 (in the direction intersecting the inclined surface). The forming process of the winding start end using this device is carried out in the following procedure. That is, at the end of winding on a certain spool, for example, the first
The tip processing device 6 in Fig. 1 is advanced from the retracted position to the welding wire side (in the penetrating direction of the paper in Fig. 11),
Insert the wire W into the slit groove 15 and insert it into the inner part 14.
and cut the wire W at the chain line X position. At this time, as shown in FIG. 13, the tip of the wire W is made to protrude a certain length forward from the open end of the slit groove 15 in the longitudinal direction. This protruding length l is determined according to the length of the loop that forms the locking structure at the winding start end by the subsequent bending process. Next, as shown in FIG. 14, the first bending member 9 is advanced in the direction of arrow a along the left inclined surface 11a of the tongue-shaped convex portion 11, and the wire W protruding outside the slit groove 15 is guided through the bending member 9. (at this point, the wire W is gripped by the feeding roller 5 and prevented from moving backward), the wire W is pushed from the tip of the slit groove 15 toward the inclined surface 11a. The wire is bent like a turn to form a hook portion on the center side of the wire winding. Subsequently, the second bending member 10 is advanced in the direction of arrow b, and the second bending member 10 is pressed while pressing the tip of the wire W protruding obliquely downward of the tongue-shaped convex portion 11 toward the passing gap forming recess 12. When the wire W is press-fitted into the passing gap forming recess 12, as shown in FIG. A bent portion that is folded back from the tip of the bending member 10 along the outer surface of the evacuation convex portion 13 at the tip end of the wire, and bent in a direction away from the passage gap of the winding wire of the spool (in a direction away from the slit groove 15). can be formed in the same plane as the hook part. After the molding is completed, as shown in FIG. 16, the first bending member 9 and the second bending member 10 are retracted in the direction of the arrows, and the support member 8 is further retracted in the direction of the paper, and the wire is pulled out from the slit groove 15. , it may be removed from the tip processing device 6. The winding start end processing method of the present invention can be automatically formed by adopting the above-mentioned apparatus and procedure, and this can be changed as appropriate depending on the difference in the locking structure. The above embodiments are merely representative examples.
