Description

Technical Field

[0001] The utility model relates to the field of animal husbandry machinery, in particular to an annealing insulation guide wheel of a copper drawing machine. Background Art

[0002] The principle of continuous annealing copper drawing machine is to pass current through the stretched copper wire (its microstructure is damaged during stretching, and the grains are distorted and coarse). It uses its own resistance to heat to the recrystallization temperature range of copper and then quickly cools and recrystallizes to achieve the purpose of refining the grains, eliminating work hardening, and improving the electrical and mechanical properties of the wire.

[0003] The annealing device uses low-voltage, high-current annealing (maximum annealing voltage 55V, annealing current 5000A). This requires high insulation performance. Any degradation of insulation performance will affect the service life of the insulating guide pulleys and the quality of the copper wire. Therefore, each annealing device must be insulated from the machine casing. During production, the upper and lower annealing pulleys of the annealing heating device heat the stretched copper wire. The insulating guide pulley between the upper and lower annealing pulleys increases the length of the copper wire heated to ensure effective heating. The high temperature of the copper wire causes the insulating guide pulleys to heat up.

[0004] At the same time, the annealing device not only has a heating device, but also a cooling device. Cooling the annealing liquid during the production process can easily cause the insulation performance of the insulating guide wheel to decrease. During use, the insulating guide wheel temperature is too high and the insulation performance is reduced, resulting in a short service life and easy damage to the bearing. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an annealing insulating guide wheel for a copper drawing machine which can better insulate heat and electricity.

[0006] In order to solve the above technical problems, the utility model includes an inner wheel and an outer wheel, the inner wheel and the outer wheel are connected by an insulating wheel, the inner wheel passes through the shaft, the shaft and the inner wheel are rotatably connected by a bearing, the shaft is hollow inside, the inner wheel has an inner cavity, an air outlet is provided at the position of the shaft corresponding to the inner cavity, a plurality of through holes connected to the inner cavity are provided on the side of the inner wheel, one end of the shaft is connected to one end of the air supply pipe, and the other end of the air supply pipe is connected to the fan.

[0007] In order to further improve the heat dissipation effect, the outer end of the through hole is connected to the air duct, and the air outlet end of the air duct points to the side of the insulating wheel.

[0008] Preferably, the cross-section of the insulating wheel is T-shaped.

[0009] In order to prevent the copper wire from being easily detached from the outer ring of the outer wheel, the cross section of the outer wheel is Y-shaped.

[0010] Preferably, the insulating wheel is made of bakelite.

[0011] In order to dissipate heat to the inner wheel and the insulating wheel more evenly, the through holes on the same side are evenly distributed in a ring around the central axis of the inner wheel.

[0012] In order to improve the heat dissipation effect, the air duct is made of copper.

[0013] To sum up, the insulating wheel of the present invention itself has the characteristics of heat insulation and insulation, which can effectively reduce the heat transfer between the outer wheel and the inner wheel. In addition, cold air is injected into the inner cavity, and then the cold air is discharged from the through hole and the air duct and blown to the side of the insulating wheel, which can not only dissipate heat for the inner wheel, but also for the insulating wheel. The side of the insulating wheel can also be kept dry by the blowing effect, avoiding the insulation effect of the insulating wheel surface being reduced due to factors such as moisture caused by annealing liquid during the annealing process, which can effectively improve the service life of the insulating guide wheel and the service life of the bearing.

[0016] Figure 2 This is a schematic diagram of the positional relationship between the insulating guide wheel, the upper annealing wheel and the lower annealing wheel of the present invention. DETAILED DESCRIPTION

[0017] Refer to the attached Figure 1-2 The annealing insulating guide wheel of the copper drawing machine includes an inner wheel 1 and an outer wheel 2, which are connected by an insulating wheel 3. The inner wheel 1 passes through the shaft 4, and the shaft 4 is rotatably connected to the inner wheel through a bearing. The shaft 4 is hollow inside, and the inner wheel has an inner cavity 5. An air outlet 6 is provided at the position of the shaft 4 corresponding to the inner cavity. A plurality of through holes 7 connected to the inner cavity are provided on the side of the inner wheel. The outer ends of the through holes 7 are connected to an air duct 8, and the air outlet end of the air duct 8 points to the side of the insulating wheel. One end of the shaft 4 is connected to one end of the air supply pipe 9, and the other end of the air supply pipe is connected to the fan. Cold air is injected into the inner cavity through the operation of the fan, and then the cold air is discharged from the through holes and the air duct and blown to the side of the insulating wheel, which can not only dissipate heat for the inner wheel, but also dissipate heat for the insulating wheel. The side of the insulating wheel can also be kept dry and clean by the blowing action, thereby avoiding the insulation effect being reduced due to factors such as moisture or impurities caused by the annealing liquid during the annealing process on the surface of the insulating wheel.

[0018] The insulating wheel is preferably made of bakelite, which not only has good insulation and heat insulation effects, but also has good strength, low cost and easy processing.

[0019] The cross-section of the insulating wheel is T-shaped. This design can make the distance between the outer wheel and the inner wheel passing through the insulating wheel larger when the diameter of the insulating wheel is the same, and the insulation and heat insulation effect is better.

[0020] The cross-section of the outer wheel is Y-shaped, and the outer wheel and the outer ring of the insulating wheel are fixedly connected by means of a slot and fixing bolts. This design can not only ensure that the copper wire is located on the outer ring of the outer wheel and is not easy to fall off, but also facilitate the connection between the outer wheel and the insulating wheel.

[0021] The inner wheel comprises two parts arranged on both sides of the inner ring of the insulating wheel. This design allows for better assembly and facilitates installation of the insulating wheel.

[0022] The through holes on the same side are evenly distributed in a ring around the central axis of the inner wheel. This design can dissipate heat to the inner wheel and the insulating wheel more evenly.

[0023] The air duct is made of copper to improve the heat dissipation effect.

[0024] Working principle: the insulating guide wheel is located between the upper annealing wheel 10 and the lower annealing wheel 11, which can increase the heating length of the copper wire. The insulating wheel itself has the characteristics of heat insulation and insulation, which can effectively reduce the heat transfer between the outer wheel and the inner wheel. In addition, cold air is injected into the inner cavity, and then the cold air is discharged from the through hole and the air duct and blown to the side of the insulating wheel, which can not only dissipate heat for the inner wheel, but also for the insulating wheel. The side of the insulating wheel can be kept dry by blowing air, avoiding the insulation effect of the insulating wheel surface being reduced due to factors such as moisture caused by the annealing liquid during the annealing process, which can effectively improve the service life of the insulating guide wheel and the service life of the bearing.

[0025] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
