Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in FIG. 1-FIG. 3, the present invention provides a method for winding and fixing a metal wire groove. The method includes: placing the wire 2 around the bottom end 22 of the wire groove 1; pressing the top of the circular punch against the wire groove At the top 21 of 1, hit the end of the round punch with a metal hammer, so that a circular depression fixing point 3 appears at the top 21 of the wire groove 1; one end of the fixing point 3 is located within the range of the top 21 of the wire groove 1, and the other end protrudes from the The top 21 of the groove 1 fixes the wire 2 in the wire groove 1; around the wire groove 1, the punch is continuously struck with a metal hammer, so that a plurality of circular concave fixing points 3 appear on the top 21 of the wire groove 1, and the whole circle of the wire 2 is all fixed. Bottom end 22 of wire slot 1.

Specifically, in the embodiment of the present invention, the wire groove 1 is preferably a copper wire groove, the wire groove 1 is divided into a top end 21 and a bottom end 22, and the bottom end 22 of the wire groove 1 is arranged between the two top ends 21 of the wire groove 1, Mainly used to place wire 2. Place the wire 2 around the bottom end 22 of the wire groove 1, then place the top of the round punch on the top 21 of the wire groove 1, hit the end of the round punch with a metal hammer, and adjust according to the actual situation. The strength and angle of the percussion, under the impact force of the circular punch, the top 21 of the wire groove 1 will be recessed downward to form a circular fixed point 3, and one side of the circular fixed point 3 is located at the top 21 of the wire groove 1. Within the range, the other side will protrude from the top 21 of the wire slot 1 and contact the wire 2 located at the bottom end 22 of the wire groove 1, and the wire 2 will be stably clamped at the bottom end 22 of the wire groove 1, so that the wire 2 will not fall off. When fixing the wire 2, the wire 2 needs to be wrapped around the bottom end 22 of the wire groove 1 as a whole, and the wire 2 is wrapped around the bottom end 22 of the wire groove 1. Multiple fixing points 3 are required to fix the wire 2 on each surface. Therefore, it is necessary to surround the wire 2. For wire groove 1, use a metal hammer to strike a circular punch to form a plurality of circular concave fixing points 3 at the top 21 of wire groove 1, so that the wire 2 is integrally fixed around the bottom end 22 of wire groove 1. The method for fixing the wire in the metal wire slot of the embodiment of the present invention has reliability when fixing the wire, the wire is not easily damaged during the fixing process, and has high processing efficiency, and can be used as a general method for fixing wires in metal wire grooves such as copper and aluminum.

Further, the depth of the wire groove 1 is 0.8mm-1.2mm, the width of the bottom end 22 of the wire groove 1 is 0.8mm-1.2mm, and the width of the top end 21 of the wire groove 1 is 1.5mm-1.8mm.
