Description

Technical Field

[0001] This utility model relates to the technical field of copper wire processing equipment, and in particular to a copper wire drawing oil return pipe. Background Technology

[0002] In traditional wire drawing processes, drawing oil is typically delivered via a direct current method. However, when the temperature of the drawing oil rises to a certain level, its viscosity also increases. This increased viscosity directly leads to increased friction during the drawing process. Excessive friction can damage the copper rod, thereby affecting its quality and reducing its performance. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a copper wire drawing oil return pipe.

[0004] The technical solution of this utility model is implemented as follows:

[0005] This utility model provides a copper wire drawing oil return pipe, and a coolant flow channel is installed below the return pipe;

[0006] The return oil pipeline includes:

[0007] The oil inlet area is located at the first end of the oil return pipe;

[0008] An oil outlet area is located at the second end of the return oil pipe, and the portion of the return oil pipe near the oil outlet area has an oil outlet pipe.

[0009] A cooling zone is located between the first and second ends of the return oil pipe, and the portion of the return oil pipe in the cooling zone is equipped with several baffle groups arranged sequentially along its length.

[0010] The baffle assembly includes a serrated baffle and several straight baffles. The serrated baffle is installed near the oil inlet area, and the several straight baffles are installed near the oil outlet area. The several straight baffles include a type I straight baffle and a type II straight baffle that are equidistantly and alternately arranged. The type I straight baffle is fixedly connected to the left side wall of the return oil pipe and extends to the right side for a predetermined length, while the type II straight baffle is fixedly connected to the right side wall of the return oil pipe and extends to the left side for a predetermined length.

[0011] The advantages or beneficial effects of the above technical solutions include at least the following:

[0012] By adding a coolant flow channel at the bottom of the return oil pipe, the temperature inside the return oil flow channel can be effectively reduced, thus effectively cooling the drawing oil. Furthermore, by using serrated baffles in the baffle assembly, copper powder can be effectively filtered out, thereby blocking these copper powder particles and ensuring the purity of the drawing oil. At the same time, the design of the straight baffles allows the drawing oil to circulate in an S-shaped flow path within the return oil pipe. This design not only increases the residence time of the drawing oil in the return oil flow channel but also helps to further improve the cooling effect. Attached Figure Description

[0027] Reference Figure 1 and Figure 2 A copper wire drawing oil return pipe 10 is provided, with a coolant flow channel 20 installed below the return pipe 10. The coolant flow channel 20 continuously pumps and discharges coolant, creating a low temperature inside the coolant flow channel 20. The temperature of the drawing oil in the return pipe 10 is conducted to the bottom of the return pipe 10, and the high temperature is carried away through the coolant flow channel 20 to cool the drawing oil in the return pipe 10.

[0028] Furthermore, the return oil pipeline 10 includes:

[0029] Oil inlet area 11 is located at the first end of return oil pipe 10, such as Figure 5 As shown, the drawing oil is poured in from above the oil inlet area 11;

[0030] The oil outlet area 12 is located at the second end of the oil return pipe 10, and the portion of the oil return pipe 10 near the oil outlet area 12 has an oil outlet pipe.

[0031] Cooling zone 13 is located between the first end and the second end of return oil pipe 10. The drawing oil is cooled by passing through cooling zone 13 from oil inlet zone 11 and finally discharged from oil outlet zone 12. Furthermore, a number of baffle groups 14 are installed in the part of return oil pipe 10 in cooling zone 13, arranged sequentially along its length.

[0032] The baffle assembly 14 includes a serrated baffle 141 and several straight baffles 142. The serrated baffle 141 is installed near the oil inlet area 11, and the drawing oil will first pass through the serrated baffle 141. The several straight baffles 142 are installed near the oil outlet area 12, and the several straight baffles 142 include a type I straight baffle and a type II straight baffle arranged at equal intervals and alternately. The type I straight baffle is fixedly connected to the left side wall of the return oil pipe 10 and extends to the right side for a predetermined length. The type II straight baffle is fixedly connected to the right side wall of the return oil pipe 10 and extends to the left side for a predetermined length, such as... Figure 3 As shown, the first type of flat baffle 142 and the second type of flat baffle 142 cause the drawing oil to flow in an S-shaped path, which greatly increases the residence time of the drawing oil in the return oil pipe 10 and increases the cooling efficiency.

[0033] Specifically, the upper part of the serrated partition 141 has a serrated structure, which allows the drawing oil to pass through the serrated partition 141 without overflowing the top of the partition. Figure 6 As shown, when the drawing oil passes through the serrated baffle 141, the drawing oil with a higher liquid level will first pass through the serrated gap, while the drawing oil with a lower liquid level will form a vortex below the serrated baffle 141 due to the flow velocity difference, causing the copper powder remaining in the drawing oil to settle at the bottom. As a further improvement, the return oil pipe 10 is provided with a recess 131 near the serrated baffle 141. The recess 131 is located in the direction of the serrated baffle 141 near the oil inlet area 11. Furthermore, the return oil pipe 10 also has an upwardly extending baffle area 132 in the direction of the recess 131 near the oil inlet area 11 to collect copper powder, making the copper powder sedimentation area more concentrated and facilitating the cleaning of copper powder.

[0034] The return oil pipe 10 adopts overflow flow. After the drawing oil is injected into the oil inlet area 11, it will accumulate in the oil inlet area 11. When it accumulates to a certain height, it overflows the serrated baffle 141 and moves forward. Preferably, in the baffle group 14, the distance between the serrated baffle 141 and the straight baffle 142 is X1, and the distance between the straight baffles 142 and the distance between two adjacent baffle groups 14 are all X2; where X1>X2> X1, thereby increasing the flow distance of the drawing oil after passing through the baffle, forming a buffer zone, and reducing the flow rate of the drawing oil, such as Figure 5 As shown.

[0035] Based on further improvements to the above structure, the return oil pipeline 10 satisfies the following formula: H1=H2; where H1 is the height of the return oil pipe 10 and H2 is the height of the baffle assembly 14, which can prevent the drawing oil from splashing onto the cover plate 16 during the flow process, and ensure that personnel will not be splashed by the drawing oil when opening the cover plate 16 for inspection.

[0036] Furthermore, the baffle assembly 14 is detachably installed inside the return oil pipe 10. The bottom wall of the return oil pipe 10 has several slots 15, and the baffles of the baffle assembly 14 can be inserted into the slots 15 for easy cleaning by the staff. A receiving groove 143 is provided on the surface of the baffle, and an elastic roll 1431 is installed in the receiving groove 143. One end of the elastic roll 1431 is embedded in the baffle, and the other end is curled and extends into the receiving groove 143, so that the middle part of the elastic roll 1431 extends out of the receiving groove 143. The inner wall of the slot 15 has a snap-fit ​​groove 151, and the middle part of the elastic roll 1431 can be inserted into the snap-fit ​​groove 151. The elastic roll 1431 can firmly fix the baffle in place, and when the user removes the baffle, due to the elastic deformation of the elastic roll 1431, the user can remove and install the baffle effortlessly.

[0038] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
