Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a wire rod attachment device that supplies and fixes a wire to an iron core block formed by overlapping plate-shaped iron cores.

[Background technology]

Conventionally, when a wire made of lead wire is fixed to an iron core block as a spacer, an adhesive is used for the bonding. The iron core block is made by stacking E-shaped plate-shaped iron cores. However, since adhesive is used, drying equipment is required, making the equipment large-scale.
There is also the problem of foul odors and pollution. Furthermore, there is a problem that an adhesive is required, which increases the cost.

[Purpose of invention]

The purpose of this invention is to provide a wire rod attachment device that can efficiently fix wire rods without using adhesives, eliminates the need for drying equipment, eliminates bad odors, and reduces costs.

[Disclosure of the invention] This invention uses a press to press the wire against the end face of the plate-shaped core of the core block, thereby deforming the wire so that it penetrates into the overlapping surface of each core and fixing the wire. . Therefore, the wire can be fixed without using adhesive.

Embodiment An embodiment of this invention is shown in FIGS. 1 to 4. In the figure, reference numeral 1 denotes a placement stand on which the iron core block 2 is placed. The iron core block 2 is made up of a plurality of E-shaped plate-shaped iron cores 2a stacked one on top of the other, and is arranged facing upward. A wire feeding device 3 feeds the wire 4 onto the iron core block 2, and is composed of a rotatable drum 5 on which the wire 4 is wound, and a pair of feed rollers 6 that feed the wire 4 while sandwiching it therebetween. The wire rod 4 is made of lead wire. Above the placement table 1, there are installed an elevating chuck device 7 that grips the tip of the wire 4 and supplies it onto the core block 2, and a press machine 8 that presses the wire 4 against the core block 2. 9 is a cutting device installed near the placement table 1, and an upper cutting blade 9a that moves up and down.
and a fixed lower cutting edge 9b.

Operation: The wire rod 4 is fed out from the drum 5 by the feeding roller 6 and fed above the iron core block 2 on the placement table 1. The feed roller 6 can adjust the feed amount and can accommodate wire diameters of 0.8φ to 1.6φ. The wire rod 4 fed onto the core block 2 is gripped by an elevating chuck device 7, and in this state is cut into a fixed size by a cutting device 9. The cut wire rod 4 of fixed size is lowered by the elevating chuck device 7, and the wire rod 4 is moved to the iron core block 2.
Supplied on top. Thereafter, the wire rod 4 is pressed against the iron core block 2 by a press machine 8. As a result of this pressing, the wire rod 4 is deformed as shown in FIG. 2, and is press-fitted into the overlapping surface of each core 2a of the core block 2, thereby being fixed to the core block 2.

In this way, since the wire rod 4 is fixed by pressing, no adhesive is required, and therefore no drying equipment is required, and space can be saved. Moreover, since it is compact, this wire rod attachment device can be made into a unit and incorporated into the equipment process. Furthermore, since no adhesive is used, bad odors can be eliminated, and there is no need for adhesives, resulting in lower costs.

Note that this invention can be applied not only to lead wire but also to solder feeding, etc. In addition to the E-shaped core block 2, it can also be used for T-shaped core blocks or core blocks made by stacking plate cores of various shapes.

[Effect of idea]

The wire rod attachment device of this invention can efficiently fix wire rods without using adhesives, and has the effect of saving space by eliminating the need for drying equipment, eliminating bad odors, and reducing costs.
