[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. However, it should be understood that the specific embodiments described herein are intended solely to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following descriptions to avoid unnecessary confusion regarding the concepts of the present invention.

[0023] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," and "top / bottom" and other terms indicating positions or locations are based on the positions or locations shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific manner, and therefore should not be construed as limitations of this utility model. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] like Figure 1-3 The wire drawing equipment system shown here combines centralized and decentralized water supply and cooling, including a main water supply pipeline 1, the water inlet end of the main water supply pipeline 1 is connected to the water outlet of the circulating water pool 2, and the water outlet end of the main water supply pipeline 1 is connected to the water inlet end of several water supply branch pipelines 11.

[0025] Specifically, a plurality of centralized water supply pumps 12 are provided on the main water supply pipeline 1, and the water in the circulating water pool 2 is extracted by the centralized water supply pumps 12. The centralized water supply pumps 12 can be provided with multiple spares as needed. The power of the centralized water supply pumps 12 is 30Kw.

[0026] The water outlet of the water supply branch pipe 11 is connected to the water inlet of the cooling water pipe 31 of the wire drawing equipment 3 through the booster pump 13. The power of the booster pump 13 is 2.2 Kw.

[0027] The cooling water pipeline 31 of the wire drawing equipment 3 includes a first cooling water branch pipeline 311 for supplying water to the working chamber 310 of the extrusion and stretching working area and a second cooling water branch pipeline 312 for supplying water to the rolling area of ​​the drawing reel 320. A sprinkler 313 is connected to the end of the second cooling water branch pipeline 312.

[0028] The wire 4 in the working chamber 310 of the extrusion and stretching working area passes through the working channels of the wire drawing pressure die 302 and the wire drawing sizing die 303. Lubricating material such as lubricating powder is provided in the working channels for lubrication.

[0029] The wire 4 is squeezed, stretched and deformed in the drawing pressure die 302 and the drawing sizing die 303 , generating a large amount of heat during this process, and lubricating powder is required to assist in the process.

[0030] The first water inlet end of the return water pipeline is connected to the overflow return water pipe 304 in the working chamber 310 of the extrusion and stretching working area, and the second water inlet end of the return water pipeline is connected to the return water pipe 321 of the rolling area of ​​the drawing reel 320. The water outlet end of the return water pipeline is connected to the water inlet of the circulating water pool 2.

[0031] Because of the above structure, the working principle of the utility model is:

[0032] The cooling water of the first cooling water branch line 311 is injected into the working chamber 310 through the water inlet of the working chamber 310, so that the drawing pressure die 302 and the drawing sizing die 303 are completely immersed in the coolant for cooling. The coolant is discharged through the overflow return pipe 304, taking away the heat at the same time.

[0033] Processing water pressure and flow can greatly improve the cooling effect. Configuring a machine-side booster pump is a simple and feasible way to increase water pressure and flow.

[0034] The wire 4 is wound on the drawing reel 320 , and the wire is continuously stretched by the winding of the drawing reel 320 . The cooling water is sprayed on the inner wall of the drawing reel 320 through the sprayer 313 , thereby indirectly cooling the wire 4 . The cooled cooling water is discharged through the return pipe 321 .

[0035] The utility model mainly solves the problem of insufficient water inlet pressure and flow at the wire drawing equipment end. Due to the existence of pipeline resistance, only a centralized water supply mode is adopted. The water pressure and flow of the wire drawing equipment close to the centralized water pump can be guaranteed, while the water pressure and flow of the wire drawing equipment far away from the centralized water supply pump cannot meet the cooling requirements.

[0036] The water supply mode that combines a centralized water supply pump with a decentralized booster pump on the machine side can ensure that each wire drawing equipment receives the same cooling water pressure and flow, ensuring consistent operating conditions for each wire drawing equipment and consistent product quality. It can also reduce the power and head of the centralized water supply pump.

[0037] The basic principles and main features of the utility model and the advantages of the utility model are shown and described above.

[0038] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected. The scope of protection of the present invention shall be defined by the attached claims and their equivalents.
