Description

Technical Field

[0001] This utility model belongs to the field of conductor heat treatment technology, and in particular relates to a quenching and tempering device for copper conductors. Background Technology

[0002] Copper conductors are commonly used conductive materials with many excellent properties. Copper's conductivity is second only to silver, and it is the best among all commercial metals, reaching 100%, and even 101% in the absence of oxygen. This allows copper conductors to effectively transmit current and reduce energy loss. Copper also has excellent thermal conductivity, quickly dissipating heat, which is crucial for applications requiring heat dissipation, such as heat sinks in electronic devices. Tempering refers to a dual heat treatment method of quenching followed by high-temperature tempering, aiming to give the workpiece good comprehensive mechanical properties. High-temperature tempering refers to tempering between 500-650℃. Therefore, the tempering process allows copper conductors to achieve the desired properties. However, it still has the following drawbacks in practical use:

[0003] In the process of quenching and tempering copper conductors, the quenching and tempering process involves first quenching with quenching equipment and then tempering with tempering equipment. This requires the use of multiple pieces of equipment to perform quenching and tempering separately. The quenching and tempering operation involves a long conductor transportation route and is not very convenient.

[0004] Secondly, during the heat treatment process, after each heating of the copper conductor, transport equipment is needed to remove the heated conductor and place it into a cooling water tank, which takes a long time and is quite troublesome. Utility Model Content

[0005] The purpose of this utility model is to provide a heat treatment device for copper conductors. By setting an outer fixing sleeve, a cooling component, a lifting plate and an electric push rod, it solves the problems of the inconvenience of multiple devices required for heat treatment of copper conductors, and the cumbersome operation of removing the conductor and sending it to the cooling pool after each heating.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a heat treatment device for copper conductors, comprising an outer fixing sleeve, a cooling assembly, a lifting plate, and a second electric push rod. An insulation sleeve is fixed to the inner wall of the outer fixing sleeve. An inner sleeve is fixed to the center of the bottom of the outer fixing sleeve. The second electric push rod is fixed to the center of the bottom of the outer fixing sleeve. The telescopic rod of the second electric push rod passes through the center of the bottom of the outer fixing sleeve and through the bottom end of the inner sleeve, extending into the inner sleeve. A support frame is fixed to the telescopic end of the second electric push rod. A lifting plate is provided at the top of the outer fixing sleeve. A cooling assembly is fixed through the lifting plate. The cooling assembly includes a nozzle, and the nozzle is fixed to the center of the bottom end of the lifting plate. The nozzle is located inside the insulation sleeve. During operation, the inner sleeve is fixed within the outer fixing sleeve. Water is delivered to the inner sleeve through the cooling assembly, causing the copper conductor in the inner sleeve to be heated and cooled. The top of the outer fixing sleeve is sealed by the lifting plate, and the support frame is raised and lowered by the second electric push rod to support the copper conductor.

[0008] Furthermore, an induction heating coil is fixedly installed inside the outer fixing sleeve, and both electrodes of the induction heating coil extend through the outer fixing sleeve. The induction heating coil inside the outer fixing sleeve induces heating on the copper conductor in the inner sleeve.

[0009] Furthermore, a water outlet pipe is fixedly connected to the bottom end of the inner sleeve on one side of the electric push rod two, and the water outlet pipe passes through and extends out of the bottom end of the outer fixed sleeve. An electric control valve one is fixed around the water outlet pipe below the outer fixed sleeve. The water outlet pipe discharges water from the inner sleeve, and the electric control valve one on the water outlet pipe controls the water supply.

[0010] Furthermore, the cooling assembly also includes a fixed pipe, an electrically controlled valve two, and a water supply hose. The top end of the nozzle is fixedly connected to the fixed pipe, and the top end of the fixed pipe is fixedly connected to the water supply hose. The fixed pipe passes through the lifting plate, and the electrically controlled valve two is fixedly attached to the periphery of the fixed pipe above the lifting plate. The water supply hose delivers water to the fixed pipe and then to the nozzle, and the electrically controlled valve two controls the on / off state of the water supply through the fixed pipe.

[0011] Furthermore, the lower periphery of the outer fixing sleeve is fixed with lower connecting blocks in a circular array, and each lower connecting block is fixed with an electric push rod at its top. Each electric push rod is fixed with an upper connecting block at its telescopic end. All the upper connecting blocks are fixed with the lifting plate in a circular array around the periphery, so that the electric push rod drives the lifting plate to rise and fall during operation.

[0012] Furthermore, the support frame is movably connected in the inner sleeve, and support columns are fixed in a circular array at the bottom edge of the support frame. The bottom ends of the support columns are supported at the inner bottom of the inner sleeve, providing support for the support frame within the inner sleeve.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inconvenient operation requiring multiple devices for tempering copper conductors by incorporating an outer fixed sleeve, cooling components, a lifting plate, and an electric push rod II. After the copper conductor in the inner sleeve is spray-quenched, the second electric control valve is opened to supply water to the inner sleeve for spray-quenching. After the cooling water stops boiling, the first electric control valve is opened to discharge the water through the outlet pipe, and then the first electric control valve is closed. The induction heating coil is restarted to heat the copper conductor. After heating for a certain period, the first electric push rod is restarted to drive the lifting plate to the top of the outer fixed sleeve to heat the copper conductor. After holding the conductor at that temperature for a certain period, the quenching and cooling process is repeated. Then, the first electric push rod and the top cover are activated, simultaneously driving the support frame to lift the cooled copper conductor to the top of the outer fixed sleeve. After removal, the work is complete. This makes the tempering device for copper conductors much more convenient, eliminating the need for multiple devices.

[0015] This invention solves the problem of cumbersome operation in tempering devices for copper conductors, which requires removing the conductor and placing it in a cooling tank after each heating process by setting up an outer fixed sleeve, cooling components, and a lifting plate. The copper conductor is placed inside the inner sleeve, and with the lifting plate pressing down on the top of the outer fixed sleeve, the induction heating coil is first activated to induction heat the copper conductor in the insulation sleeve. During quenching or tempering, once the copper conductor reaches the appropriate temperature, the induction heating coil is turned off, and then the second electric control valve is opened. The water delivery hose delivers water to the fixed pipe, then to the nozzle, and finally sprays it into the inner sleeve. By falling onto the copper conductor within the inner sleeve, the copper conductor is quenched or tempered, making the cooling operation during tempering much more convenient.

Specific Implementation Example 1

[0026] Please see Figure 1-3 This utility model relates to a heat treatment device for copper conductors, comprising an outer fixing sleeve 1, a cooling assembly 2, a lifting plate 3, and an electric push rod 4. An insulation sleeve 102 is fixed to the inner wall of the outer fixing sleeve 1. During operation, the outer fixing sleeve 1 holds the insulation sleeve 102 and the inner sleeve 103 within it. The inner sleeve 103 is fixed to the center of the bottom of the outer fixing sleeve 1, and during operation, the inner sleeve 103 accommodates the copper conductor being heat-treated. The electric push rod 4 is fixed to the center of the bottom of the outer fixing sleeve 1. The telescopic rod of the electric push rod 4 passes through the center of the bottom of the outer fixing sleeve 1 and through the bottom end of the inner sleeve 103, extending into the inner sleeve 103. A support frame 401 is fixed to the telescopic end of the electric push rod 4. The support frame 401 supports the copper conductor that needs to be heat-treated. During operation, the electric push rod 4 drives the support frame 401 to rise and fall, which in turn drives the copper conductor supported on the support frame 401 to rise and fall. The top of the outer fixed sleeve 1 is provided with a lifting plate 3, which closes the top of the outer fixed sleeve 1 and the inner sleeve 103. A cooling component 2 is fixedly installed inside the lifting plate 3. The cooling component 2 cools down the heat-treated copper conductor in the inner sleeve 103. The cooling component 2 includes a nozzle 201. The nozzle 201 is fixed in the center of the bottom end of the lifting plate 3. The nozzle 201 is installed inside the heat insulation sleeve 102. After the quenching or cooling water is sprayed out from the nozzle 201, the copper conductor in the inner sleeve 103 is cooled down.

[0027] Specifically, an induction heating coil 101 is fixedly installed inside the outer fixed sleeve 1, and both electrodes of the induction heating coil 101 extend through the outer fixed sleeve 1. The two electrodes of the induction heating coil 101 are connected to the output terminal of an external control device, so that the induction heating coil 101 is electrically connected to the external control device. When the outer fixed sleeve 1 is working, the induction heating coil 101 induction heats the copper conductor in the inner sleeve 103.

[0028] Furthermore, a water outlet pipe 104 is fixedly connected to the bottom end of the inner sleeve 103 on one side of the electric push rod 2 4. The bottom end of the water outlet pipe 104 is connected to the cooling and purifying water equipment. The water outlet pipe 104 passes through and extends out of the bottom end of the outer fixed sleeve 1. An electric control valve 105 is fixed around the water outlet pipe 104 below the outer fixed sleeve 1. After the water in the inner sleeve 103 is collected at the bottom, it enters the water outlet pipe 104 and is discharged into the cooling and purifying equipment.

[0029] Furthermore, the cooling assembly 2 also includes a fixed pipe 202, an electrically controlled valve 203, and a water supply hose 204. The top end of the nozzle 201 is fixedly connected to the fixed pipe 202, and the top end of the fixed pipe 202 is fixedly connected to the water supply hose 204. The fixed pipe 202 passes through the lifting plate 3. The electrically controlled valve 203 is fixed around the fixed pipe 202 above the lifting plate 3. The end of the water supply hose 204 away from the fixed pipe 202 is connected to the water supply equipment to deliver water into the fixed pipe 202, and then into the nozzle 201. The fixed pipe 202 controls the on / off supply of cooling water through the electrically controlled valve 203.

[0030] The operation process of this embodiment is as follows: During operation, the copper conductor is placed inside the inner sleeve 103. At the same time, after the lifting plate 3 presses on the top of the outer fixed sleeve 1, the induction heating coil 101 is first started to induction heat the copper conductor in the insulation sleeve 102. During quenching or tempering, after the copper conductor is heated to a suitable temperature, the induction heating coil 101 is turned off, and the second electric control valve 203 is directly opened. The water supply hose 204 delivers water to the fixed pipe 202, then to the nozzle 201, and then sprays it into the inner sleeve 103. By falling onto the copper conductor in the inner sleeve 103, the copper conductor is sprayed for quenching or tempering and cooling. Specific Implementation Example 2

[0031] Please see Figure 1-6Based on the first specific embodiment, the lower part of the outer fixed sleeve 1 is fixed with lower connecting blocks 303 in a ring array. Each lower connecting block 303 has an electric push rod 302 fixed to its top. Each electric push rod 302 has an upper connecting block 301 fixed to its telescopic end. All the upper connecting blocks 301 are fixed in a ring array around the lifting plate 3. All the electric push rods 302 are connected to the same controller to synchronously control the lifting and lowering operations. The lower connecting block 303 at the bottom of the electric push rod 302 is fixed to the outer fixed sleeve 1, supporting the bottom of the electric push rod 302 on the fixed sleeve. The upper connecting block 301 at the telescopic end of the electric push rod 302 is fixed to the lifting plate 3. During the lifting process driven by the electric push rod 302, the lifting plate 3 is driven to lift and lower.

[0032] Specifically, the support frame 401 is movably connected in the inner sleeve 103, and the bottom edge of the support frame 401 is fixed with support columns 402 in a circular array. The bottom ends of the support columns 402 are supported and set in the inner bottom of the inner sleeve 103. The support columns 402 at the bottom of the support frame 401 are supported and set in the inner bottom of the inner sleeve 103 after descending to the lower part of the inner sleeve 103, thus supporting the support frame 401 in the inner sleeve 103.

[0033] The operation process of this embodiment is as follows: First, the electric push rod 302 is activated, driving the upper connecting block 301 to rise. During this rise, the lifting plate 3 is also raised. After the lifting plate 3 has risen to a suitable height, the electric push rod 4 is activated, driving the support frame 401 to rise to its top, level with the top of the inner sleeve 103. Then, the copper conductor requiring heat treatment is placed on the support frame 401. Next, the electric push rod 4 is activated again, lowering the support frame 401 until it is supported by the support column 402 within the inner sleeve 103. The electric push rod 302 then drives the lifting plate 3 to descend to the top of the outer fixed sleeve 1. The copper conductor can then be heated by the induction heating coil 101. After heating the copper conductor for a suitable time, the electric push rod 302 is activated again, driving the lifting plate 3 to rise... After raising the height of the nozzle 201, open the second electric control valve 203 to deliver water to the inner sleeve 103, spraying and quenching the copper conductor in the inner sleeve 103. After the cooling water stops boiling, open the first electric control valve 105 to discharge the water through the outlet pipe 104, then close the first electric control valve 105 and restart the induction heating coil 101 to heat the copper conductor. After heating for a certain period of time, restart the first electric push rod 302 to drive the lifting plate 3 to descend to the top of the outer fixed sleeve 1, keeping the copper conductor warm and performing tempering operations on the copper conductor. After keeping it warm for a certain period of time, repeat the above quenching and cooling steps, then start the first electric push rod 302 and the second electric push rod 4 to raise the lifting plate 3. At the same time, the support frame 401 drives the conductor to rise to the top of the outer fixed sleeve 1, and removes it to complete the work.
