[0003] In the prior art including the aforementioned patents, water cooling or air cooling methods are commonly used. However, water has a large specific heat capacity, but its cooling speed is relatively slow compared to salt water at room temperature. Furthermore, it is prone to freezing at low temperatures, affecting the cooling effect and normal operation of the equipment. Air has a small specific heat capacity, limited cooling capacity, and the slowest cooling speed, making it difficult to meet the requirements for rapid cooling in the production of automotive chassis fastener wires. Therefore, it is necessary to design a wire drawing cooling device for automotive chassis fastener wire production with a fast cooling speed. Utility Model Content

[0004] The purpose of this invention is to provide a wire drawing and cooling device for automotive chassis fastener wire production, in order to solve the problem of slow water and air cooling speeds at room temperature mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire drawing and cooling device for automobile chassis fastener wire production, comprising a base, a support frame mounted on the top of the base, a drive motor fixedly connected to the top of the support frame, a drive wheel fixedly connected to the output shaft of the drive motor via a coupling, a telescopic rod mounted on the internal bearing of the support frame, a housing fixedly connected to the top of the base, a fastening base mounted on the inner wall bearing of the housing, a cooling assembly installed inside the housing, a connecting shaft fixedly connected to one side of the fastening base, a wire drawing roller fixedly connected to the outer wall of the connecting shaft, a cooling base mounted on one side of the wire drawing roller, a conduit fixedly connected to the outer wall of the cooling base, and an adjustment assembly mounted on the top of the base.

[0006] Furthermore, one end of the telescopic rod is connected to another drive wheel, and the drive wheel is connected to the other drive wheel via belt drive. The outer wall of the housing is provided with a wire drawing hole.

[0007] Furthermore, the other end of the telescopic rod is engaged with the fastening base, and the fastening base is fixed with bolts.

[0008] Furthermore, the cooling assembly internally includes a compressor, a condenser, a throttle valve, an evaporator, a brine tank, a brine pump, pipes, and a control box. The compressor is installed inside the chassis, a condenser is installed on one side of the compressor, a throttle valve is installed on one side of the condenser, an evaporator is installed on the inner wall of the chassis, a brine tank is fixedly connected to the inner wall of the chassis, a brine pump is installed on one side of the outer wall of the brine tank, a pipe is fixedly connected to the output end of the brine pump, and a control box is installed on the outer wall of the chassis.

[0009] Furthermore, the compressor, condenser, throttle valve, evaporator, brine tank, and brine pump are interconnected by pipes, and the output end of the pipes is connected to a conduit.

[0010] Furthermore, the adjustment assembly includes a slide rail, an adjustment frame, a retrieval rod, a retrieval rocker, and a pad. The top of the base is fixedly connected to the slide rail, the adjustment frame is slidably mounted on the top of the slide rail, the retrieval rod is mounted at the center of the adjustment frame, the retrieval rocker is mounted on one side of the bottom of the adjustment frame, and the pad is fixedly connected to the top of the adjustment frame.

[0011] Furthermore, the recovery rocker arm is connected to the lower part of the recovery rod via a belt, the pad is located below the drawing roller, and bolt fastening rings are provided on the four inner rods of the adjustment frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the wire drawing and cooling device for automobile chassis fastener wire production is reasonable and has the following advantages:

[0013] (1) The wire drawing process of the upper automobile chassis fastener wire is cooled by the designed cooling component. The cooling process is carried out by brine cooling. After a series of treatments inside the cooling component, the temperature of the contact position on the upper part is reduced, thereby cooling the temperature after wire drawing. The brine has a large specific heat capacity, can absorb more heat while its own temperature rises relatively little, and its freezing point is lower than that of pure water. It can remain liquid at a lower temperature, so it can reduce the temperature of the wire more quickly, improve the cooling efficiency, and help improve production efficiency. After the brine cooling operation, the wire structure can be made finer and more uniform, thereby improving the strength, toughness and hardness of the wire and other mechanical properties, meeting the strict requirements of automobile chassis fasteners for wire quality. At the same time, compared with air cooling and other methods, brine cooling can quickly cool the surface of the wire, reduce the contact time and reaction degree between the wire and oxygen in the air, reduce the possibility of surface oxidation, help maintain the smoothness and quality of the wire surface, and reduce the surface treatment process in subsequent processing.

[0014] (2) The wire drawing position can be adjusted by adjusting the components. The height of the pad can be adjusted by adjusting the adjustment frame, thereby adjusting the gap between the wire drawing roller and the pad, thereby controlling the wire drawing diameter. By adjusting the wire drawing process, the diameter and shape of the wire can be precisely controlled to meet the high-precision size requirements of automotive chassis fasteners. Different types of fasteners may require different specifications of wire. Adjustable wire drawing can ensure that the size deviation of the produced wire is within a very small range, improving the consistency and interchangeability of the product. At the same time, by reasonably adjusting the wire drawing parameters, the wear and load of the equipment can be reduced, the service life of the equipment can be extended, and the maintenance cost and downtime of the equipment can be reduced.

[0023] Example 1:

[0024] A wire drawing and cooling device for automotive chassis fastener wire production includes a base 1, a support frame 2 mounted on the top of the base 1, a drive motor 3 fixedly connected to the top of the support frame 2, a drive wheel 4 fixedly connected to the output shaft of the drive motor 3 via a coupling, a telescopic rod 5 mounted on the internal bearing of the support frame 2, a housing 6 fixedly connected to the top of the base 1, a fastening base 7 mounted on the inner wall bearing of the housing 6, a cooling assembly 8 installed inside the housing 6, a connecting shaft 9 fixedly connected to one side of the fastening base 7, a wire drawing roller 10 fixedly connected to the outer wall of the connecting shaft 9, a cooling base 11 mounted on one side of the wire drawing roller 10, a conduit 12 fixedly connected to the outer wall of the cooling base 11, and an adjustment assembly 13 mounted on the top of the base 1.

[0025] The above structure uses a designed cooling component 8 to cool the wire drawing process of the upper automobile chassis fasteners. The cooling process is carried out by salt water cooling. After a series of treatments inside the cooling component 8, the temperature of the contact position on the upper part is reduced, thereby cooling down the temperature after wire drawing.

[0026] Furthermore, one end of the telescopic rod 5 is connected to another drive wheel 4, and the drive wheel 4 is connected to the other drive wheel 4 via belt drive. The outer wall of the housing 6 is provided with a wire drawing hole, and the other end of the telescopic rod 5 is engaged with the fastening base 7, which is fixed by bolts.

[0027] The above structure is connected by a belt for transmission, and the telescopic rod 5 is fixed by the fastening base 7, which facilitates the installation of the original wire drawing material.

[0028] Furthermore, the cooling assembly 8 includes a compressor 801, a condenser 802, a throttle valve 803, an evaporator 804, a brine tank 805, a brine pump 806, a pipe 807, and a control box 808. The compressor 801 is installed inside the casing 6. The condenser 802 is installed on one side of the compressor 801, and the throttle valve 803 is installed on one side of the condenser 802. The evaporator 804 is installed on the inner wall of the casing 6. The brine tank 805 is fixedly connected to the inner wall of the casing 6. The brine pump 806 is installed on one side of the outer wall of the brine tank 805. The output end of the brine pump 806 is fixedly connected to the pipe 807. The control box 808 is installed on the outer wall of the casing 6. The compressor 801, condenser 802, throttle valve 803, evaporator 804, brine tank 805, and brine pump 806 are interconnected through the pipe 807, and the output end of the pipe 807 is connected to the conduit 12.

[0029] The above-mentioned structure, after being cooled with brine, can make the wire structure more compact and uniform, thereby improving the mechanical properties of the wire such as strength, toughness and hardness, and meeting the strict requirements of automotive chassis fasteners for wire quality.

[0030] Furthermore, the internal components of the adjustment assembly 13 include a slide rail 1301, an adjustment frame 1302, a recovery rod 1303, a recovery rocker arm 1304, and a pad 1305. The slide rail 1301 is fixedly connected to the top of the base 1. The adjustment frame 1302 is slidably mounted on the top of the slide rail 1301. The recovery rod 1303 is mounted at the center of the adjustment frame 1302. The recovery rocker arm 1304 is mounted on one side of the bottom of the adjustment frame 1302. The pad 1305 is fixedly connected to the top of the adjustment frame 1302. The recovery rocker arm 1304 is connected to the lower part of the recovery rod 1303 via a belt. The pad 1305 is located below the drawing roller 10. Bolt fastening rings are provided on the four rods inside the adjustment frame 1302.

[0031] The above structure allows for precise control of the wire diameter and shape by adjusting the wire drawing process.

[0032] Working principle: When in use, first, the unprocessed wire is installed on the outside of the telescopic rod 5, and the telescopic rod 5 is fixed by the fastening base 7. The wire drawing part of the machine box 6 is heated to facilitate the wire drawing process. The wire is passed through the wire drawing hole on the machine box 6 and through the gap between the wire drawing roller 10 and the pad 1305 for wire drawing.

[0033] Secondly, the cooling base 11 is slidably installed with the drawing roller 10, and the conduit 12 is connected to the cooling assembly 8. The low-temperature brine in the bottom brine cooling is passed into the conduit 12, and the cooling base 11 is used for cooling treatment. The designed cooling assembly 8 is used to cool the wire drawing process of the upper automobile chassis fastener wire. The brine cooling method is used for cooling treatment. After a series of treatments inside the cooling assembly 8, the temperature of the contact position on the upper part is reduced, thereby reducing the temperature after drawing. The brine has a large specific heat capacity, can absorb more heat while its own temperature rises relatively little, and its freezing point is lower than that of pure water. It can remain liquid at a lower temperature, so it can reduce the temperature of the wire more quickly, improve the cooling efficiency, and help improve production efficiency. After the brine cooling operation, the wire structure can be made finer and more uniform.

[0034] Finally, the wire drawing position can be adjusted by adjusting component 13, and the height of pad 1305 can be adjusted by adjusting bracket 1302, thereby adjusting the gap between wire drawing roller 10 and pad 1305, thereby controlling the wire drawing diameter. By adjusting the wire drawing process, the diameter and shape of the wire can be precisely controlled to meet the high-precision dimensional requirements of automotive chassis fasteners. The wire after drawing is recycled by using recovery rocker 1304 to drive recovery rod 1303.
