Description

Technical Field

[0001] This utility model relates to the field of steel wire heat treatment technology, and in particular to a tool for quickly disconnecting broken wires in a continuous steel wire heat treatment production line. Background Technology

[0002] In the continuous heat treatment production line for steel wire, the ends of steel wires from different feed spools are welded together at the feed end using a welding machine to ensure continuous production. Wire breakage during production can be caused by various factors, including uneven feed spool switching, wire embedding on the feed spool flange, poor wire routing leading to wire clamping, wire inclusions in the coil, and weak welding.

[0003] To ensure product quality and production line efficiency, after a wire breaks on the production line, it must be repaired according to regulations. The wire to be repaired must first be threaded through a heating furnace that is over 20 meters long. A needle is a common auxiliary tool for threading the wire through the furnace; it is approximately 30 meters long, slightly longer than the heating furnace, and weighs over 30 kilograms.

[0004] When splicing broken wires, the steel wire to be spliced ​​is prepared at the furnace inlet. Workers fix the wire to the tip of the needle, then place the needle into the needle slot. Two workers push the needle towards the furnace outlet until the needle head reaches the outlet. A third worker then uses a tool at the furnace outlet to remove the wire from the needle, thus completing the wire splicing process inside the furnace. After splicing, because the wire cannot automatically return to its original position, it needs to be manually moved back to its original position.

[0005] Currently, needle-threading tools are bulky and heavy, resulting in wasted costs. At the same time, the method of using needles to assist in wiring has disadvantages such as slow speed, high manpower requirements, long time consumption, and complicated operation. Utility Model Content

[0023] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: As Figures 1-3 As shown, a tool for quickly cutting broken wires in a continuous heat treatment production line for steel wire includes a tool body, a first horizontal part 1 at the top of the tool body, a second horizontal part 2 at the bottom, and a first vertical part 3 and a second vertical part 4 connected between the two horizontal parts; the first vertical part 3 has a strip groove 5, and the second vertical part 4 has several strip-shaped movement grooves 6, which pass through the first horizontal part 1 and communicate with the top of the strip groove 5; wire holes 7 are provided on the left and right sides of the first vertical part 3 and the second vertical part 4.

[0025] The tool body is a hollow cuboid shape with a wall thickness of 2mm. The length of the first horizontal part 1 is less than that of the second horizontal part 2. The first horizontal part 1 is 120mm long and 23mm wide, the second horizontal part 2 is 134mm long and 23mm wide, and the height of the first vertical part 3 and the second vertical part 4 is 23mm.

[0026] The two ends of the strip groove 5 are rounded, and the top of the strip groove 5 and the junction with the positioning groove 6 are provided with a concave arc.

[0027] There are five routing slots 6 in total. The routing slots 6 are 3.5mm wide and are arranged at equal intervals of 20mm.

[0028] The first horizontal section 1, the first vertical section 3, the second horizontal section 2, and the second vertical section 4 are all connected by a circular arc transition.

[0029] A further improvement of this utility model is that the included angles between the first vertical part 3, the second vertical part 4 and the second horizontal part 2 are all 55°.

[0030] The threading holes 7 are located at the bottom of the left and right sides of the first vertical part 3 and the second vertical part 4.

[0031] Example 2: This example is a further improvement on Example 1. The main improvement is that Example 1 had some serious problems during use; however, in this example, the above-mentioned defects can be avoided. Specifically: Both the first horizontal section 1 and the second horizontal section 2 are provided with six process holes 8, and the process holes 8 are arranged at equal intervals of 20mm; the positioning groove 6 is arranged alternately with the process holes 8; in this embodiment, both the first horizontal section 1 and the second horizontal section 2 are provided with six process holes 8, which further reduces the weight of the tool.

[0032] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0033] The specific working principle of this utility model is as follows: This tool has four wire-threading holes 7 at both ends and five wire-tracking grooves 6 in the middle. The spacing of the wire-tracking grooves 6 is set to be equal to the spacing of the wires on the production line. When splicing a broken wire, at the furnace inlet, the wire to be spliced ​​is passed through the wire-threading holes of the tool and tied in place. Then, the tool's track 6 is placed on the normally produced wire on the production line. The friction between the track 6 and the normally produced wire allows the tool to pass through the furnace body while being supported by the normally produced wire. When it reaches the furnace outlet, the wire separator will block the tool. The operator uses other tools to remove the tool and pull the wire to be spliced ​​out of the furnace outlet, completing the wire-threading operation.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
