Description

Technical Field

[0001] This utility model relates to the field of steel wire quenching technology, specifically a quenching spray device for steel wire processing. Background Technology

[0002] Wire quenching is a heat treatment process that mainly consists of two steps. First, the wire is heated and then rapidly cooled. During the heating process, the grains of the wire expand, which plastically confines the grain boundaries in different directions, resulting in higher strength and hardness of the wire.

[0003] Currently, during the quenching process of steel wire, the heated steel wire needs to be sprayed with quenching liquid to cool it rapidly. However, the nozzles in existing quenching liquid spraying devices are usually fixed in different places, so the quenching liquid and steel wire cannot be in uniform contact, which reduces the cooling efficiency of the steel wire. To address this, we propose a quenching spraying device for steel wire processing. Utility Model Content

[0004] The purpose of this invention is to provide a quenching spray device for steel wire processing. During the steel wire quenching spraying process, the nozzle can be oscillated, so that the quenching liquid sprayed from the nozzle can come into uniform contact with the steel wire, thereby improving the cooling efficiency of the steel wire and promoting uniform cooling of the steel wire, thus improving the quenching quality. This invention solves the problem in existing steel wire quenching liquid spraying devices where the nozzles are usually fixed, resulting in uneven contact between the quenching liquid and the steel wire, which reduces the cooling efficiency of the steel wire.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quenching spray device for steel wire processing, comprising an annular tube, a fixed ring, and nozzles. The annular tube is rotatably mounted on the front surface of the fixed ring via a bearing. A plurality of nozzles are fixedly mounted in an annular array at equal intervals on the inner wall of the annular tube. An arc-shaped slider is fixedly mounted on the rear surface of the annular tube. An arc-shaped groove is provided on the front surface of the fixed ring, and the arc-shaped slider is located inside the arc-shaped groove. A spring is provided on one side inside the arc-shaped groove. A rotating motor is fixedly mounted on the upper surface of the fixed ring. A lever is fixedly connected to the end of the output shaft of the rotating motor. A lever block is fixedly mounted on the upper surface of the annular tube.

[0006] Preferably, four fixing blocks are fixedly mounted in a ring array at equal intervals on the outer surface of the fixing ring, and each of the four fixing blocks has a mounting hole on its front surface.

[0007] Preferably, an inlet pipe is fixedly connected to the outer surface of the annular tube.

[0008] Preferably, the outer surface of the lever is provided with an installation port, and a roller is rotatably installed inside the installation port.

[0009] Preferably, a buffer block is fixedly installed on the side of the outer surface of the arc-shaped slider that is away from the spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a fixed ring, bearing, annular tube, nozzle, rotating motor, lever, lever block, arc-shaped slider, arc-shaped groove, and spring, achieves the effect of allowing the nozzle to swing during the steel wire quenching spraying process. This ensures that the quenching liquid sprayed from the nozzle makes uniform contact with the steel wire, thereby improving the cooling efficiency of the steel wire and promoting uniform cooling, thus improving the quenching quality. After the heated steel wire passes through the annular tube, the quenching liquid inside the annular tube is sprayed onto the steel wire through the nozzle. The rotating motor drives the lever to rotate. After the lever and lever block come into contact, they cause the annular tube to rotate. When the lever and lever separate, the compressed spring is released, causing the arc-shaped slider to slide back to its original position. This cycle repeats, and the nozzle sprays the quenching liquid in an oscillating manner, ensuring uniform contact between the quenching liquid and the steel wire, thereby improving the cooling efficiency of the steel wire and promoting uniform cooling, thus improving the quenching quality.

[0012] 2. By setting a buffer block, the present invention can buffer the arc-shaped slider when it slides back to its original position under the action of the spring, thus avoiding strong impact and extending the service life of the arc-shaped slider.

[0013] 3. By setting up an installation port and rollers, this utility model achieves the effect of reducing the wear of the lever. The setting of rollers changes the sliding friction between the lever and the lever block into rolling friction between the lever and the rollers, thus avoiding the wear of the lever block and reducing the wear of the lever, and extending the service life of the lever.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figures 1-4 As shown, the present invention proposes a quenching spray device for steel wire processing, comprising an annular tube 1, a fixed ring 3, and nozzles 6. The annular tube 1 is rotatably mounted on the front surface of the fixed ring 3 via a bearing 2. An inlet pipe 7 is fixedly connected to the outer surface of the annular tube 1, through which quenching fluid is input into the interior of the annular tube 1. Several nozzles 6 are fixedly mounted in a ring array at equal intervals on the inner wall of the annular tube 1, through which the quenching fluid inside the annular tube 1 is sprayed out. An arc-shaped slider 11 is fixedly mounted on the rear surface of the annular tube 1, and an arc-shaped groove 15 is provided on the front surface of the fixed ring 3. The slider 11 is located inside the arc-shaped groove 15. A spring 16 is provided on one side inside the arc-shaped groove 15. A buffer block 10 is fixedly installed on the outer surface of the arc-shaped slider 11 away from the spring 16. When the arc-shaped slider 11 slides back to its original position under the action of the spring 16, the buffer block 10 can buffer the arc-shaped slider 11, avoid strong impact, and extend the service life of the arc-shaped slider 11. A rotating motor 4 is fixedly installed on the upper surface of the fixed ring 3. A lever 5 is fixedly connected to the end of the output shaft of the rotating motor 4. A lever block 12 is fixedly installed on the upper surface of the annular tube 1.

[0022] In use, the heated steel wire passes through the annular tube 1, and the quenching liquid inside the annular tube 1 is sprayed onto the steel wire through the nozzle 6. The rotating motor 4 drives the lever 5 to rotate. After the lever 5 contacts the lever block 12, it causes the annular tube 1 to rotate. When the lever block 12 separates from the lever 5, the compressed spring 16 is released, causing the arc-shaped slider 11 to slide back to its original position. This cycle repeats, and the nozzle 6 sprays the quenching liquid in an oscillating manner, which makes the quenching liquid and the steel wire come into uniform contact, thereby improving the cooling efficiency of the steel wire and promoting uniform cooling of the steel wire, thus improving the quenching quality.

[0023] Example 2

[0024] like Figures 1-4 As shown, the present invention proposes a quenching spray device for steel wire processing. Compared with the first embodiment, this embodiment further includes four fixing blocks 8 fixedly installed in a ring array at equal intervals on the outer surface of the fixing ring 3. The front surface of each of the four fixing blocks 8 is provided with mounting holes 9. The outer surface of the lever 12 is provided with a mounting port 14. A roller 13 is rotatably installed inside the mounting port 14. The roller 13 is made of rubber. When the lever 5 contacts the roller 13, the rubber roller 13 also plays a buffering role.

[0025] In this embodiment, the roller 13 transforms the sliding friction between the lever 5 and the lever block 12 into rolling friction between the lever 5 and the roller 13, thus avoiding wear on the lever block 12, reducing wear on the lever 5, and extending the service life of the lever 5.

[0026] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
