Description

Technical Field

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

[0002] Copper-chromium-zirconium alloy contact wire is mainly composed of copper, chromium, zirconium and other elements. Due to its high strength, high conductivity and good comprehensive performance, copper-chromium-zirconium alloy contact wire is widely used in high-speed electrified railway contact network. It needs 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 wire, the contact wire is usually quenched; In the prior art, in order to improve the quenching efficiency, quenching equipment is usually used to continuously quench the contact wire. For example, Chinese patent publication number CN221166637U discloses a high-strength and high-conductivity copper wire rapid quenching device. The device alternately quenches the high-strength and high-conductivity copper wire by setting a plurality of quenching plates. When taking and loading materials, the quenching device body can continue to work without stopping, thereby improving the working efficiency of the quenching device.

[0003] When the existing wire quenching device is working, the quenching efficiency can be improved to a certain extent by continuously performing quenching treatment. However, in the actual operation process, a certain amount of quenching liquid will adhere to the surface of the wire, which will not only cause additional loss of quenching liquid, but also increase the processing cost of wire quenching. In addition, the adhesion of quenching liquid on the surface of the wire will also have an adverse effect on the subsequent processing of the wire. An additional process is required to clean the quenching liquid on the surface of the contact wire, which will increase the workload of contact wire quenching. Summary of the invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 9 A heat treatment device for producing copper-chromium-zirconium alloy contact wire for high-speed railway, comprising a liquid collecting box 11 and a contact wire 12, wherein the outer surface of the contact wire 12 is provided with a mounting groove 13, the inner surface of the liquid collecting box 11 is fixedly connected with a connecting plate 21, the upper side of the connecting plate 21 is fixedly connected with a rotating sleeve 40, and the inner side of the rotating sleeve 40 is rotatably connected with a fixing rod 27; A wave assembly is provided on the upper side of the connecting plate 21, and the wave assembly 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, and the outer surface of the traction plate 33 is inclined, and a guide block 34 is slidably connected to the outer surface of the upper end of the traction plate 33, and a fixed rod 20 is fixedly connected to the outer surface of the upper end of the guide block 34, and the lower side of the outer surface of the fixed rod 20 is in movably contact with the inner surface of the sleeve 32, and the upper ends of the fixed rod 20 and the fixed rod 27 are fixedly connected to the tray 19, and the tray 19 is in rotational contact with the inner surface of the mounting groove 13.

[0021] The outer surface of the upper end of the liquid collecting box 11 is open, the connecting plates 21 are in two groups and are symmetrically distributed, the outer surface of the tray 19 is arc-shaped, the mounting grooves 13 are in two groups and are symmetrically distributed, the trays 19 are in several groups and are distributed in a parallel array, and the trays 19 are used to pull and transport the contact line 12.

[0022] By adopting the above technical scheme, in the production and processing process 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 collecting box 11 lifts and supports the rotating sleeve 40 through the connecting plate 21, and the rotating sleeve 40 is used to rotationally support the fixed rod 27. The tray 19 at the upper end of the fixed rod 27 is engaged in the mounting groove 13 on the surface of the contact wire 12. The contact wire 12 is pulled and supported by the tray 19 and the mounting groove 13. The contact wire 12 is cooled and quenched by the coolant during transportation, and the tray 19 is driven to rotate. The lower end of the tray 19 at the front end is fixedly connected to the fixed rod 20, and the connecting plate 21 is connected through the sleeve. 32 is a movable support for the fixed rod 20. The tray 19 drives the fixed rod 20 to rotate and at the same time drives the guide block 34 on the lower side to rotate synchronously. Under the action of the gravity of the contact line 12 and the tray 19, the lower end of the guide block 34 will slide in contact with the outer surface of the traction plate 33. The traction plate 33 is inclined, so the fixed rod 20 will slide back and forth up and down inside the sleeve 32. The fixed rod 20 will drive the tray 19 to move up and down during the movement, so that the front end of the contact line 12 can be driven by the tray 19 to fluctuate. The fluctuation of the contact line 12 can shake off the coolant on its surface, thereby effectively reducing the residual coolant on the surface of the contact line 12, and then effectively reducing the waste of coolant, and then effectively reducing the heat treatment cost of the contact line 12.

[0023] like Figure 3 and Figure 5As shown, a spray assembly is provided at the upper end of the liquid collecting tank 11, and the spray assembly includes a fixing frame 14 fixedly connected to the outer surface of the upper end of the liquid collecting tank 11, the upper outer surface of the fixing frame 14 is fixedly connected to the liquid storage tank 15, the lower outer surface of the liquid storage tank 15 is fixedly connected to a connecting pipe 46, the lower end of the connecting pipe 46 is fixedly connected to a spray pipe 47, and the lower side of the outer surface of the spray pipe 47 is embedded and fixedly connected to a nozzle 48.

[0024] The spray pipe 47 is arc-shaped, the inner surface of the liquid storage tank 15 is fixedly connected to the refrigeration plate 22, the outer surface of the right end of the liquid storage tank 15 is fixedly connected to the return pipe 17, the lower end of the return pipe 17 is connected to the inside of the liquid collecting tank 11, and the lower end of the return pipe 17 is fixedly connected to the water pump 26.

[0025] The fixing frame 14 is in a U-shaped structure, and the front and rear ends of the outer surface of the fixing frame 14 are fixedly connected with curtains 16, and the curtains 16 are made of flexible material. The left and right ends of the outer surface of the fixing frame 14 are provided with ventilation grilles 18, and the number of the refrigeration plates 22 is several groups and is distributed in parallel up and down.

[0026] By adopting the above technical solution, the liquid collecting tank 11 supports the liquid storage tank 15 through the fixing frame 14. When the contact wire 12 is quenched, the coolant inside the liquid storage tank 15 enters the spray pipe 47 through the connecting pipe 46, and then sprays from the nozzle 48 on the surface of the spray pipe 47 to the surface of the contact wire 12, so that the contact wire 12 can be quenched continuously. The spray pipe 47 is in an arc shape, so that multiple groups of nozzles 48 can spray coolant at different angles to quench and cool the contact wire 12. Excess coolant drips from the surface of the contact wire 12 and collects in the liquid collecting tank 11. At the same time, the water pump 26 is started and operated, and the water pump 2 6 and the return pipe 17 transport the coolant in the collecting tank 11 to the inside of the liquid storage tank 15. 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, thereby improving the quenching quality of the contact line 12. The curtain 16 on the surface of the fixing frame 14 can have a certain sealing effect on both ends of the fixing frame 14, thereby effectively reducing the splashing of the coolant outward, thereby further reducing the loss of the coolant. The ventilation grille 18 on the surface of the fixing frame 14 helps the circulation of gas inside the fixing frame 14, which is beneficial to the dissipation of heat inside the fixing frame 14.

[0027] like Figure 5 and Figure 8As shown, an expansion component is provided on the inner side of the liquid collecting box 11, and the expansion component includes a bracket 35 fixedly connected to the inner surface of the front end of the liquid collecting box 11, and a placement groove 36 is provided on the outer surface of the upper end of the bracket 35. A capsule 37 is fixedly connected to the inner surface of the placement groove 36, and a liquid absorbent cotton 39 is fixedly connected to the inner surface of the capsule 37. The inner surface of the liquid absorbent cotton 39 is in sliding contact with the outer surface of the contact line 12.

[0028] The sac 37 is in a circular ring shape, and a cavity 38 is provided inside the sac 37. The cavity 38 is filled with thermal expansion gas. The number of the absorbent cotton 39 is several groups and distributed in a ring array. The absorbent cotton 39 is in an arc shape. An overflow hole 49 is opened through the lower end of the inner surface of the placement groove 36. The absorbent cotton 39 is made of elastic material.

[0029] By adopting the above technical scheme, in order to further reduce the residual coolant on the surface of the contact line 12, the contact line 12 is passed through the middle of the capsule 37, and the placement groove 36 opened on the surface of the bracket 35 is used to support the capsule 37. The inner side of the capsule 37 is provided with a ring-shaped array of absorbent cotton 39. During the continuous transportation of the contact line 12, the absorbent cotton 39 will continue to slide in contact with the surface of the contact line 12, so that the coolant remaining on the surface of the contact line 12 can be adsorbed and recovered, thereby effectively improving the recovery effect of the coolant. The cavity 38 inside the capsule 37 is filled with an appropriate amount of thermal expansion gas. During the process of the absorbent cotton 39 being in contact with the surface of the contact line 12, the residual heat of the contact line 12 will be transferred to the inside of the capsule 37 through the absorbent cotton 39, and the thermal expansion gas in the cavity 38 will expand due to the heat, thereby gradually increasing the volume of the capsule 37. The expansion of the capsule 37 can make the absorbent cotton 39 and the surface of the contact line 12 fit more closely, thereby further improving High cooling liquid recovery effect. When the contact line 12 fluctuates, the tray 19 will only move downward a certain distance, which will cause the contact line 12 to squeeze the absorbent cotton 39 on the lower side. The absorbent cotton 39 is made of elastic material and can produce a certain degree of elastic deformation. At this time, the coolant adsorbed inside the absorbent cotton 39 will be discharged into the placement groove 36 under the action of pressure, and discharged to the inside of the collecting box 11 through the overflow hole 49 on the lower side of the placement groove 36, thereby further improving the recovery quality of the coolant and helping to reduce the loss of coolant. By setting an expansion component, not only can the absorbent cotton 39 be used to absorb the coolant on the surface of the contact line 12, but the expansion of the capsule 37 can make the absorbent cotton 39 and the surface of the contact line 12 fit more closely, and the fluctuation of the contact line 12 can squeeze the absorbent cotton 39, thereby effectively improving the absorption effect of the coolant on the surface of the contact line 12, and helping to achieve the recycling of the coolant.

[0030] like Figure 3 and Figure 6As shown, a cooling assembly is provided on the inner side of the tray 19 located inside the fixed frame 14, and the cooling assembly includes a through hole 30 opened on the upper surface of the tray 19, the interior of the tray 19 is hollow, and a guide plate 29 is fixedly connected to the inner surface of the tray 19, and mesh holes 28 are opened on the lower side of the outer surface of the tray 19, and the number of the mesh holes 28 is several groups and distributed in a ring array.

[0031] By adopting the above technical scheme, during the spray quenching process of the contact wire 12, in order to prevent the coolant from being unable to fully contact the inside of the installation groove 13, a cooling component is arranged on the inner side of the tray 19. During the spraying process, 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 flow to the edge of the tray 19 under the guidance of the guide plate 29, and then the coolant will flow out to the outside of the tray 19 through the mesh 28 on the surface of the tray 19. During the transportation of the contact wire 12, the tray 19 will continue to rotate, so that the coolant can be discharged into the inside of the installation groove 13, and the internal area of ​​the installation groove 13 is quenched by the coolant, thereby effectively improving the quenching quality of the contact wire 12, so that the contact wire 12 can be evenly quenched.

[0032] like Figure 1 As shown, a shaking assembly is provided on the inner side of the liquid collecting box 11, and the shaking assembly includes a receiving plate 31 fixedly connected to the inner surface of the liquid collecting box 11, and the lower side of the receiving plate 31 is arc-shaped and located on the lower side of the contact line 12. The number of the receiving plates 31 is two groups and they are distributed in parallel, and a limiting plate 44 is fixedly connected between the two groups of receiving plates 31.

[0033] The outer surface of the fixing rod 27 is fixedly connected with a rotating wheel 42, the outer surface of the rotating wheel 42 is fixedly connected with a paddle 43, the outer surface of the lower end of the limiting plate 44 is fixedly connected with a stopper 45, the outer surface of the paddle 43 is in sliding contact with the outer surface of the stopper 45, and the receiving plate 31 is made of elastic material.

[0034] By adopting the above technical scheme, during the spray quenching process of the contact line 12, part of the coolant will remain on the surface of the receiving plate 31. The receiving plate 31 is located at the lower side of the contact line 12, and the coolant on its surface can contact the lower area of ​​the contact line 12, so that the lower area of ​​the contact line 12 can be quenched by the coolant. The fixed rod 27 will drive the rotating wheel 42 to rotate synchronously during the rotation, and the rotating wheel 42 will drive the paddle 43 to make a circular motion. The paddle 43 will contact the block 45 during the movement, and the limit plate 44 can be driven to move in the horizontal direction through the block 45. The limit plate 44 will pull the receiving plate 31 during the movement. The receiving plate 31 is made of elastic material and can produce a certain degree of elastic deformation. The coolant on its surface can be discharged through the swing of the receiving plate 31, and the swing of the receiving plate 31 will drive the coolant to fully contact with the lower surface of the contact line 12, thereby effectively improving the quenching quality of the contact line 12.

[0035] Instructions for use: When the contact wire 12 is quenched, the tray 19 is engaged in the mounting groove 13 on the surface of the contact wire 12. The tray 19 cooperates with the mounting groove 13 to pull and support the contact wire 12. The contact wire 12 will drive the tray 19 to rotate synchronously during the movement. The coolant inside the liquid storage tank 15 enters the spray pipe 47 through the connecting pipe 46, and then is sprayed from the nozzle 48 on the surface of the spray pipe 47 to the surface of the contact wire 12, so that the contact wire 12 can be quenched continuously. The fixing rod 20 will drive the tray 19 to move up and down during the movement, so that the front end of the contact wire 12 can be driven to fluctuate through the tray 19. The coolant on its surface can be shaken off through the fluctuation of the contact wire 12, and the contact wire 12 absorbs the coolant during the continuous transportation process. The liquid cotton 39 will continuously slide in contact with the surface of the contact line 12, so that the coolant remaining on the surface of the contact line 12 can be adsorbed and recovered. The expansion of the capsule 37 can make the liquid absorbent cotton 39 and the surface of the contact line 12 fit more closely, thereby further improving the recovery effect of the coolant. The coolant adsorbed inside the liquid absorbent cotton 39 will be discharged into the placement groove 36 under the action of pressure, and discharged into the collecting 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. The coolant on its surface can be discharged by the swing of the receiving plate 31, and the swing of the receiving plate 31 will drive the coolant to fully contact with the lower surface of the contact line 12, thereby effectively improving the quenching processing quality of the contact line 12.
