Description

Technical Field

[0001] This utility model belongs to the technical field of quenched conductive wheels, specifically relating to a quenched conductive wheel processed from welded strips. Background Technology

[0002] The quenching conductive wheel is a key component used in contact resistance heating quenching processes. It is mainly used for surface strengthening of metal workpieces. Its core principle is to apply electricity to the workpiece through contact wheel, using contact resistance to generate high temperature to heat the workpiece surface, followed by rapid cooling to achieve quenching.

[0003] However, the current quenched conductive wheel generates instantaneous high temperature when in continuous contact with the welding strip, and the quenched conductive wheel is prone to overheating and deformation.

[0004] Therefore, a method for processing quenched conductive wheels using welding strips is proposed. Summary of the Invention

[0005] This invention provides a quenched conductive wheel for welding strip processing, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a quenching conductive wheel for welding strip processing, including a carbon brush assembly and a conductive wheel. The carbon brush assembly is located below the conductive wheel. A copper drive shaft is disposed at the center of the outer side wall of the conductive wheel. A copper guide wheel is disposed at one end of the copper drive shaft. Welding strip is wound around the outer side wall of the copper guide wheel. The carbon brush assembly includes: a fixed frame located directly below the conductive wheel and a support arm hinged to the outer side wall of the fixed frame; a spring disposed between the fixed frame and the support arm; a graphite brush disposed at one end of the support arm; and a guide wheel cooling assembly disposed at one side of the copper guide wheel.

[0007] Furthermore, the guide wheel cooling assembly includes a collection cover located on one side of the copper guide wheel. A mating cavity is formed on the outer wall of one side of the copper guide wheel. A copper inner plate is embedded and fixed inside the mating cavity. A U-shaped cooling channel is provided inside the copper inner plate. A drain channel and a liquid inlet channel are provided inside the copper inner plate. The drain channel is located on one side of the liquid inlet channel.

[0008] Furthermore, a drain pipe is provided on one side of the outer wall of the copper inner plate at a position connected to one end of the drain channel, and an insulating coolant input pipe is rotatably connected at the center of one side of the outer wall of the copper inner plate at a position connected to the inlet channel.

[0009] Furthermore, a liquid collection pipe is provided at the bottom of the collection hood, and a circular groove is provided on the outer side of one side of the collection hood near the outer side of the drain pipe.

[0010] Furthermore, the insulating coolant inlet pipe passes through the collection cover, and one end of the insulating coolant inlet pipe is connected to an external pump, and insulating coolant is introduced into the inside of the insulating coolant inlet pipe;

[0011] Furthermore, the two ends of the U-shaped cooling channel are respectively connected to one end of the drain channel and one end of the inlet channel;

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention, through its interconnected inlet channel, U-shaped cooling channel, and outlet channel, allows insulating coolant to flow inside the copper guide wheel, thereby carrying away the overheated heat from the copper guide wheel and cooling it down. This prevents the copper guide wheel from overheating and deforming. The collection cover collects the discharged coolant, avoiding the problem of coolant splashing out at high speed due to centrifugal force and being unable to be collected.

[0014] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1-4 This utility model embodiment proposes a welding strip processing quenching conductive wheel, including a carbon brush assembly 1 and a conductive wheel 2. The carbon brush assembly 1 includes a fixing frame 11 located directly below the conductive wheel 2. A support arm 12 is hinged to the outer wall of the fixing frame 11. A graphite brush 14 is provided on one side of the outer wall of the support arm 12 close to the side of the conductive wheel 2. A spring 13 is provided between the support arm 12 and the fixing frame 11.

[0023] By pulling the support arm 12 by the spring 13, the graphite brush 14 is pressed against the conductive wheel 2, and DC current is input into the conductive wheel 2. The current is transmitted to the copper wire wheel 4 through the copper drive shaft 3, forming a closed circuit.

[0024] A copper drive shaft 3 is provided at the center of one side of the outer wall of the conductive wheel 2. A copper guide wheel 4 is provided at one end of the copper drive shaft 3. A welding strip 5 is wound on the outer side wall of the copper guide wheel 4. When the welding strip 5 comes into contact with the high-speed rotating copper guide wheel, the contact resistance generates instantaneous high temperature, thereby realizing metal recrystallization (quenching).

[0025] The guide wheel cooling assembly 6 includes a collection cover 61 located on one side of a copper guide wheel 4. A mating cavity 63 is formed on the outer wall of one side of the copper guide wheel 4. A copper inner disc 62 is embedded and fixed inside the mating cavity 63. The inner copper disc 62 has a U-shaped cooling channel 64 inside, and a drain channel 65 and an inlet channel 69 inside. The drain channel 65 is located on one side of the inlet channel 69. A drain pipe 66 is provided on the outer wall of one side of the copper inner disc 62 at a position connecting to one end of the drain channel 65. Furthermore, a drain pipe 66 is located on the outer wall of one side of the copper inner disc 62. An insulating coolant inlet pipe 67 is rotatably connected at the central position and the position connected to the liquid inlet channel 69. A liquid collection pipe 68 is provided at the bottom of the collection cover 61, and a circular groove is opened on one side of the outer wall of the collection cover 61 near the outer side of the drain pipe 66. The insulating coolant inlet pipe 67 passes through the collection cover 61, and one end of the insulating coolant inlet pipe 67 is connected to an external liquid pump. Insulating coolant is introduced into the interior of the insulating coolant inlet pipe 67. The two ends of the U-shaped cooling channel 64 are respectively connected to one end of the drain channel 65 and the liquid inlet channel 69.

[0026] In use, an external pump injects insulating coolant into the insulating coolant inlet pipe 67. Since the insulating coolant inlet pipe 67 is rotatably connected to the copper inner disc 62, the insulating coolant can still be injected into the copper inner disc 62 when the copper inner disc 62 and the copper guide wheel 4 rotate synchronously. The insulating coolant flows inside the copper inner disc 62 and the copper guide wheel 4, sequentially entering the inlet channel 69, the U-shaped cooling channel 64 and the drain channel 65, and finally being discharged through the drain pipe 66. The flowing insulating coolant carries away the overheated heat on the copper guide wheel 4, thereby cooling the copper guide wheel 4 and preventing it from overheating and deforming.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
