Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing die cores, in particular to a wire drawing die core for steel wires. Background Art

[0002] The wire drawing die core usually refers to various dies for drawing metal wires, as well as wire drawing dies for drawing optical fibers. All wire drawing dies have a hole of a certain shape in the center, which can be round, square, octagonal or other special shapes. When the metal is pulled through the die hole, its size becomes smaller and even its shape changes. When drawing soft metals (such as gold and silver), a steel die is sufficient, and there can be multiple holes of different diameters on the steel die.

[0003] Generally, a certain thrust will be generated when the steel wire passes through the wire drawing die core. In order to prevent the wire drawing die from moving, the wire drawing die core needs to be fixed with a fixing device. In the wire drawing process, the wire drawing die core will also generate a lot of heat. In order to prevent overheating and mold expansion, it will not only affect the diameter of the steel wire drawing and fail to achieve the expected effect, but may also cause the mold to break.

[0004] For this purpose, we propose a wire drawing die core for steel wire. Utility Model Content

[0005] The main purpose of the utility model is to provide a wire drawing die core for steel wire. By installing the wire drawing die core into a fixing device, the position of the wire drawing die core can be fixed so that the position of the wire drawing die core will not move during the wire drawing process. In addition, in conjunction with a water inlet pipe and a spray device, a layer of cooling water mist can be sprayed on the steel wire before it enters the wire drawing die core. In addition, in the subsequent wire drawing process, the heat generated can be reduced to avoid expansion of the wire drawing die core during the process, which can effectively solve the problems in the background technology.

[0022] A water inlet pipe 9 is provided on the top of the fixing device 3, one side of the water inlet pipe 9 is fixedly connected and communicated with one end of a spray device 10, and the water spraying end of the spray device 10 is located above the feed port of the wire drawing die core 1; a mounting base 8 is provided on the bottom of the fixing device 3, one side of the fixing device 3 is fixedly connected with one side of a limit block 6, a hole 7 is provided inside the limit block 6, and the hole 7 is communicated with the discharge port of the wire drawing die core 1;

[0023] The fixing device 3 is provided with a first through slot 5, a second through slot 17, and a third through slot 16, the first through slot 5, the second through slot 17, the third through slot 16 and the cavity 18 are connected to each other, and the first through slot 5, the second through slot 17, and the third through slot 16 are provided at two locations opposite to each other; a pull rod 15 is movably installed inside the first through slot 5 and the second through slot 17, and a spring 14 is sleeved on the outer side of the pull rod 15, and the spring 14 is provided inside the second through slot 17;

[0024] One end of the spring 14 is fixedly connected to the inner wall of the second through groove 17, the other end of the spring 14 is fixedly connected to one end of the connecting plate 13, and the connecting plate 13 is movably arranged inside the second through groove 17, one end of the pull rod 15 is fixedly connected to one end of the connecting plate 13, and the other end of the pull rod 15 is provided with a pull ring 4, and the pull ring 4 is located inside the first through groove 5; one end of the connecting plate 13 away from the pull rod 15 is fixedly connected to one end of the connecting rod 12, and one end of the connecting rod 12 away from the connecting plate 13 is provided with a clamping block 11, and the connecting rod 12 and the clamping block 11 are movably arranged inside the third through groove 16 and the cavity 18.

[0025] It should be noted that the utility model is a wire drawing die core for steel wire. First, the wire drawing die core 1 is inserted into the cavity 18 in the fixing device 3.
