Description

Technical Field

[0001] The present invention relates to the field of alloy processing, and more specifically, to a heat treatment device for producing copper-chromium-zirconium alloy contact wires for high-speed railways. Background Art

[0002] Copper-chromium-zirconium alloy contact wires are mainly composed of elements such as copper, chromium, and zirconium. Due to their high strength, high conductivity, and good comprehensive performance, copper-chromium-zirconium alloy contact wires are widely used in the catenary of high-speed electrified railways and need to be processed through multiple processes such as forging, hot rolling, heat treatment, and cold rolling. In order to improve the strength and hardness of the contact wires, quenching treatment is usually carried out on the contact wires.

[0003] In the prior art, in order to improve the quenching efficiency, a quenching device is usually used to continuously quench the contact wires. For example, a Chinese patent with the publication number CN221166637U discloses a high-strength and high-conductivity copper wire rapid quenching device. This device alternately quenches the high-strength and high-conductivity copper wires by setting multiple quenching plates. When taking and loading materials, the quenching device body can continue to work without stopping, improving the working efficiency of the quenching device.

[0004] When the existing wire quenching device is working, continuous quenching treatment can improve the quenching efficiency to a certain extent. However, in the actual operation process, a certain amount of quenching liquid will adhere to the wire surface, which will not only cause additional loss of the quenching liquid, but also increase the processing cost of wire quenching. Moreover, the adhesion of the quenching liquid on the wire surface will also have an adverse impact on the subsequent processing of the wire, and additional processes are required to clean the quenching liquid on the contact wire surface, thus increasing the workload of contact wire quenching.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 to 9 , a heat treatment device for producing copper-chromium-zirconium alloy contact wires for high-speed railways, including a liquid collection tank 11 and a contact wire 12. An installation groove 13 is provided on the outer surface of the contact wire 12. A connecting plate 21 is fixedly connected to the inner surface of the liquid collection tank 11. A rotating sleeve 40 is fixedly connected to the upper side of the connecting plate 21. A second fixing rod 27 is rotatably connected inside the rotating sleeve 40;

[0035] A wave component is provided on the upper side of the connecting plate 21. The wave component includes a sleeve 32 fixedly connected to the outer surface of the upper end of the connecting plate 21. A traction plate 33 is fixedly connected to the inner surface of the sleeve 32. The outer surface of the traction plate 33 is inclined. A guide block 34 is slidably connected to the outer surface of the upper end of the traction plate 33. A first fixing rod 20 is fixedly connected to the outer surface of the upper end of the guide block 34. The lower side of the outer surface of the first fixing rod 20 is in movable contact with the inner surface of the sleeve 32. A tray 19 is fixedly connected to the upper ends of both the first fixing rod 20 and the second fixing rod 27. The tray 19 is in rotational contact with the inner surface of the installation groove 13.

[0036] The upper end outer surface of the liquid collecting tank 11 is open. The number of the connecting plates 21 is two and they are symmetrically distributed. The outer surface of the tray 19 is arc-shaped. The number of the installation grooves 13 is two and they are symmetrically distributed. The number of the trays 19 is several and they are distributed in a parallel array. The tray 19 is used for traction and conveying of the contact wire 12.

[0037] By adopting the above technical solution, during the production and processing of the copper-chromium-zirconium alloy contact wire 12, in order to improve the wear resistance and mechanical properties of the copper-chromium-zirconium alloy contact wire 12, the contact wire 12 needs to be quenched. During operation, the heated contact wire 12 is conveyed at a uniform speed. The liquid collecting tank 11 supports the rotating sleeve 40 through the connecting plate 21, and the rotating sleeve 40 rotatably supports the second fixing rod 27. The tray 19 at the upper end of the second fixing rod 27 is engaged in the installation groove 13 on the surface of the contact wire 12. The tray 19 cooperates with the installation groove 13 to tractionally support the contact wire 12. During the conveying process of the contact wire 12, it is cooled and quenched by the coolant, and the tray 19 is driven to rotate. A first fixing rod 20 is fixedly connected to the lower end of the tray 19 at the front end. The connecting plate 21 movably supports the first fixing rod 20 through the sleeve 32. When the tray 19 drives the first fixing rod 20 to rotate, it will drive the guide block 34 on its lower side to rotate synchronously. The lower end of the guide block 34 will be in sliding contact with the outer surface of the traction plate 33 under the gravity of the contact wire 12 and the tray 19. The traction plate 33 is inclined, so the first fixing rod 20 will reciprocate up and down inside the sleeve 32. During the movement of the first fixing rod 20, it will drive the tray 19 to move up and down, so that the front end of the contact wire 12 can be driven to wave through the tray 19. Through the wave of the contact wire 12, the coolant on its surface can be shaken off, so that the residual coolant on the surface of the contact wire 12 can be effectively reduced, and further the waste of the coolant can be effectively reduced, and further the heat treatment cost of the contact wire 12 can be effectively reduced.

[0038] Such as Figure 3 And Figure 5As shown in the figure, a spraying assembly is provided at the upper end of the liquid collecting tank 11. The spraying assembly includes a fixing frame 14 fixedly connected to the outer surface of the upper end of the liquid collecting tank 11. A liquid storage tank 15 is fixedly connected to the outer surface of the upper end of the fixing frame 14. A connecting pipe 46 is fixedly connected to the outer surface of the lower end of the liquid storage tank 15. A spraying pipe 47 is fixedly connected to the lower end of the connecting pipe 46. Nozzles 48 are fixedly connected to the lower side of the outer surface of the spraying pipe 47 in an embedded manner.

[0039] The spraying pipe 47 is in an arc shape. A refrigeration plate 22 is fixedly connected to the inner surface of the liquid storage tank 15. A return pipe 17 is fixedly connected to the outer surface of the right end of the liquid storage tank 15. The lower end of the return pipe 17 communicates with the inside of the liquid collecting tank 11. A water pump 26 is fixedly connected to the lower end of the return pipe 17.

[0040] The fixing frame 14 is in a U-shaped structure. Curtain shields 16 are fixedly connected to the front and rear ends of the outer surface of the fixing frame 14. The curtain shields 16 are made of flexible materials. Ventilation grilles 18 are provided on the left and right ends of the outer surface of the fixing frame 14. The number of the refrigeration plates 22 is several groups and they are distributed in parallel up and down.

[0041] By adopting the above technical solutions, the liquid collecting tank 11 supports the liquid storage tank 15 through the fixing frame 14. When quenching the contact wire 12, the coolant inside the liquid storage tank 15 enters the inside of the spraying pipe 47 through the connecting pipe 46, and then sprays out from the nozzles 48 on the surface of the spraying pipe 47 onto the surface of the contact wire 12, so that the contact wire 12 can be continuously quenched. The spraying pipe 47 is in an arc shape, so that multiple groups of nozzles 48 can spray the coolant at different angles to quench and cool the contact wire 12. The excess coolant drips from the surface of the contact wire 12 and will be collected inside the liquid collecting tank 11. At the same time, the water pump 26 is started, and the coolant inside the liquid collecting tank 11 is transported to the inside of the liquid storage tank 15 through the water pump 26 and the return pipe 17. The refrigeration plate 22 inside the liquid storage tank 15 can effectively cool the coolant, so that the temperature of the coolant can be maintained within an appropriate range, and further improve the quenching quality of the contact wire 12. The curtain shields 16 on the surface of the fixing frame 14 can play a certain sealing effect on both ends of the fixing frame 14, so that the outward splashing of the coolant can be effectively reduced, and further reduce the loss of the coolant. The ventilation grilles 18 on the surface of the fixing frame 14 contribute to the circulation of the gas inside the fixing frame 14, so that it is beneficial to the dissipation of the heat inside the fixing frame 14.

[0042] Such as Figure 5 And Figure 8As shown in the figure, an expansion component is provided inside the liquid collection tank 11. The expansion component includes a bracket 35 fixedly connected to the inner surface of the front end of the liquid collection tank 11. A placement groove 36 is formed on the outer surface of the upper end of the bracket 35. A bladder 37 is fixedly connected to the inner surface of the placement groove 36. A liquid absorption cotton 39 is fixedly connected to the inner surface of the bladder 37. The inner surface of the liquid absorption cotton 39 is in sliding contact with the outer surface of the contact wire 12.

[0043] The bladder 37 is circular ring-shaped. A cavity 38 is provided inside the bladder 37. The cavity 38 is filled with a thermally expandable gas. The number of the liquid absorption cottons 39 is several groups and they are distributed in a circular array. The liquid absorption cotton 39 is arc-shaped. An overflow hole 49 is formed through the lower end of the inner surface of the placement groove 36. The liquid absorption cotton 39 is made of an elastic material.

[0044] By adopting the above technical solution, in order to further reduce the residue of the coolant on the surface of the contact wire 12, the contact wire 12 is passed through the middle of the bladder 37. The placement groove 36 formed on the surface of the bracket 35 is used to support the bladder 37. The liquid absorption cottons 39 distributed in a circular array are provided inside the bladder 37. During the continuous transportation of the contact wire 12, the liquid absorption cottons 39 will continuously slide-contact with the surface of the contact wire 12, so as to adsorb and recover the residue of the coolant on the surface of the contact wire 12, and thus can effectively improve the recovery effect of the coolant. An appropriate amount of thermally expandable gas is filled in the cavity 38 inside the bladder 37. During the process of the liquid absorption cotton 39 being in close contact with the surface of the contact wire 12, the residual heat of the contact wire 12 will be transferred to the inside of the bladder 37 through the liquid absorption cotton 39, and the thermally expandable gas inside the cavity 38 will expand due to heat, so that the volume of the bladder 37 gradually increases. Through the expansion of the bladder 37, the liquid absorption cotton 39 can be more closely attached to the surface of the contact wire 12, and thus can further improve the recovery effect of the coolant. When the contact wire 12 fluctuates, since the tray 19 will only move downward by a certain distance, the contact wire 12 will squeeze the lower liquid absorption cotton 39. The liquid absorption cotton 39 is made of an elastic material and can produce a certain amount of elastic deformation. At this time, the coolant adsorbed inside the liquid absorption cotton 39 will be discharged into the placement groove 36 under the action of pressure and discharged into the liquid collection tank 11 through the overflow hole 49 on the lower side of the placement groove 36, and thus can further improve the recovery quality of the coolant, which helps to reduce the loss of the coolant. By providing the expansion component, not only can the liquid absorption cotton 39 be used to absorb the coolant on the surface of the contact wire 12, but also the expansion of the bladder 37 can make the liquid absorption cotton 39 more closely attached to the surface of the contact wire 12, and the contact wire 12 can squeeze the liquid absorption cotton 39 through fluctuations, and thus can effectively improve the absorption effect of the coolant on the surface of the contact wire 12, and at the same time helps to realize the recycling of the coolant.

[0045] As Figure 3 and Figure 6As shown in the figure, a cooling component is provided inside the inner side of the tray 19 located inside the fixing frame 14. The cooling component includes a through hole 30 opened on the upper surface of the tray 19. The inside of the tray 19 is hollow. A guiding plate 29 is fixedly connected to the inner surface of the tray 19. A mesh hole 28 is opened on the lower side of the outer surface of the tray 19. The number of the mesh holes 28 is several groups and they are distributed in a circular array.

[0046] By adopting the above technical solution, during the spray quenching process of the contact wire 12, in order to avoid that the coolant cannot fully contact the inside of the installation groove 13, a cooling component is provided inside the inner side of the tray 19. During the spraying process of the coolant, part of the coolant will enter the inside of the tray 19 through the through hole 30 on the surface of the tray 19, and under the guiding action of the guiding plate 29, it will flow towards the edge of the tray 19. Then the coolant flows out of the tray 19 through the mesh hole 28 on the surface of the tray 19. During the conveying process of the contact wire 12, the tray 19 will continuously rotate, so that the coolant can be discharged into the inside of the installation groove 13, and the inside area of the installation groove 13 is quenched by the coolant, thereby effectively improving the quenching quality of the contact wire 12 and enabling the contact wire 12 to be uniformly quenched.

[0047] As Figure 1 shown in the figure, a shaking component is provided inside the liquid collecting box 11. The shaking component includes a material receiving plate 31 fixedly connected to the inner surface of the liquid collecting box 11. The lower side of the material receiving plate 31 is arc-shaped and is located below the contact wire 12. The number of the material receiving plates 31 is two groups and they are distributed in parallel. A limiting plate 44 is fixedly connected between the two groups of material receiving plates 31.

[0048] A runner 42 is fixedly connected to the outer surface of the fixing rod two 27. A dial 43 is fixedly connected to the outer surface of the runner 42. A stop block 45 is fixedly connected to the outer surface of the lower end of the limiting plate 44. The outer surface of the dial 43 is in sliding contact with the outer surface of the stop block 45. The material receiving plate 31 is made of an elastic material.

[0049] By adopting the above technical solution, during the spray quenching process of the contact wire 12, some coolant will remain on the surface of the material receiving plate 31. The material receiving plate 31 is located below the contact wire 12, and the coolant on its surface can come into contact with the lower side area of the contact wire 12. Thus, the lower side area of the contact wire 12 can be quenched by the coolant. During the rotation of the second fixed rod 27, it will drive the runner 42 to rotate synchronously. The runner 42 will drive the paddle 43 to perform a circular motion. During the movement of the paddle 43, it will come into contact with the stopper 45. Through the stopper 45, the limit plate 44 can be driven to move horizontally. During the movement of the limit plate 44, it will pull the material receiving plate 31. The material receiving plate 31 is made of an elastic material and can produce a certain degree of elastic deformation. Through the swing of the material receiving plate 31, the coolant on its surface can be discharged. Moreover, the swing of the material receiving plate 31 will drive the coolant to fully contact the lower surface of the contact wire 12, thereby effectively improving the quenching processing quality of the contact wire 12.

[0050] Usage method: When quenching the contact wire 12, the tray 19 is clamped in the mounting groove 13 on the surface of the contact wire 12. The contact wire 12 is traction-supported by the tray 19 in cooperation with the mounting groove 13. During the movement of the contact wire 12, it will drive the tray 19 to rotate synchronously. The coolant inside the liquid storage tank 15 enters the spray pipe 47 through the connecting pipe 46, and then is sprayed out from the nozzles 48 on the surface of the spray pipe 47 onto the surface of the contact wire 12, so that the contact wire 12 can be continuously quenched. During the movement of the first fixed rod 20, it will drive the tray 19 to move up and down, so that the front end of the contact wire 12 can be driven to fluctuate by the tray 19. Through the fluctuation of the contact wire 12, the coolant on its surface can be shaken off. During the continuous transportation of the contact wire 12, the absorbent cotton 39 will continuously slide-contact the surface of the contact wire 12, so that the residual coolant on the surface of the contact wire 12 can be adsorbed and recovered. Through the expansion of the bladder 37, the absorbent cotton 39 can be more closely attached to the surface of the contact wire 12, thereby further improving the recovery effect of the coolant. The coolant adsorbed inside the absorbent cotton 39 will be discharged into the placement groove 36 under the action of pressure and discharged into the liquid collection tank 11 through the overflow hole 49 on the lower side of the placement groove 36, thereby further improving the recovery quality of the coolant. Through the swing of the material receiving plate 31, the coolant on its surface can be discharged. Moreover, the swing of the material receiving plate 31 will drive the coolant to fully contact the lower surface of the contact wire 12, thereby effectively improving the quenching processing quality of the contact wire 12.
