Description

Technical Field

[0001] This utility model relates to the field of copper alloy processing technology, and in particular to a rapid cooling and solidification device for copper alloys. Background Technology

[0002] Copper alloys are alloys made of pure copper as the base material and one or more other elements added. Common copper alloys are divided into three main categories: brass, bronze, and cupronickel. In the production of copper alloys, the raw materials are usually placed in a crucible in a directional solidification furnace for melting. Then, the raw materials are cast into copper alloy molds through the crucible to obtain copper alloy ingots with low gas inclusion content, high mechanical properties, and good machinability.

[0003] Currently, some copper alloys are smelted and cast by pouring the molten metal from the crucible into a mold. After casting, the end cap is opened for natural cooling. However, natural cooling is slow and uneven, which may lead to a decrease in the quality of the copper alloy.

[0004] Therefore, to address the current issue that some copper alloys are smelted and cast by pouring the molten metal from the crucible into a mold, followed by natural cooling after casting, but which is slow and uneven, potentially leading to a decrease in copper alloy quality, a rapid cooling and solidification device for copper alloys can be designed. This device consists of a cooling box, a water tank, a water pump, a mounting shell, and a cooling fan. Activating the water pump allows water from the water tank to be transported to the cooling box through suction and outlet pipes. The water then carries away the heat from the mold body and flows back to the mounting shell through a return pipe. After being cooled by the cooling fan, it flows back to the water tank, creating a circulation that rapidly cools and solidifies the copper alloy. Utility Model Content

[0005] To overcome the current problem that some copper alloys are smelted and cast by pouring the molten metal from the crucible into a mold, and then opening the end cap for natural cooling after casting, which is slow and uneven, potentially leading to a decrease in the quality of the copper alloy.

[0006] The technical solution of this utility model is as follows: a copper alloy rapid cooling and solidification device, including a smelting device; the smelting device includes a directional solidification furnace, a water tank is connected to the left side of the smelting device, mounting frames are connected to the bottom left and right sides of the directional solidification furnace, a mounting plate is connected to the top of the mounting frame, a mold body is set inside the mounting plate, a cooling box is connected to the bottom of the mounting plate, the cooling box is located outside the mold body, a water pump is installed on the top rear side of the water tank, a suction pipe is connected to the suction end of the water pump, the other end of the suction pipe is located at the top bottom of the water tank, a discharge pipe is connected to the discharge end of the water pump, the other end of the discharge pipe is located on the right side of the cooling box, a return pipe is located on the left side of the cooling box, the other end of the return pipe is located on the top left side of the water tank, a mounting shell is connected to the top of the water tank, the mounting shell is located outside the return pipe, and four cooling fans are installed on the front and rear sides of the mounting shell.

When the water in the return pipe passes through the mounting shell, the cooling fans on the front and rear sides are aligned, and the cooling fans can cool the water in the return pipe. The cooled water can then flow back to the inside of the water tank, ensuring the efficiency of subsequent cooling of the copper alloy.

[0009] Preferably, the top left and right sides of the mounting plate are connected to rotating seats, the top of the rotating seats is connected to a rotating rod, and the top of the rotating rod is connected to a rotating plate.

[0010] Preferably, a threaded seat is connected to the inner top of the rotating plate, and a threaded rod is connected to the internal thread of the threaded seat.

[0015] 1. By setting up a cooling box, water tank, water pump, mounting shell, and cooling fan, the water pump is started, which can transport water from the water tank to the cooling box through the suction pipe and the outlet pipe. The water can carry away the heat of the mold body and flow to the mounting shell through the return pipe. After being cooled by the cooling fan, it flows back to the water tank, thus forming a circulation, which can play a role in the rapid cooling and solidification of copper alloy.

The top of the water tank 7 is connected to the mounting shell 12, which is located outside the return pipe 11. Four cooling fans 13 are installed on both the front and rear sides of the mounting shell 12. After the copper alloy is cast, the water pump 8 is started. The water pump 8 can transport the water inside the water tank 7 to the cooling box 6 through the suction pipe 9 and the outlet pipe 10. After passing through the mold body 5, the water flows back to the inside of the water tank 7 through the return pipe 11, thus forming a circulation. The water can quickly carry away the heat of the mold body 5, so that the copper alloy can be cooled and solidified quickly. When the water in the return pipe 11 passes through the mounting shell 12, the cooling fans 13 on both the front and rear sides are aligned. The cooling fans 13 can cool the water in the return pipe 11. The cooled water can then flow back to the inside of the water tank 7, ensuring the efficiency of subsequent cooling of the copper alloy.

[0024] Please see Figures 4-5 In this embodiment, an annular groove 14 is provided on the top of the mounting plate 4, and a sealing ring 15 is provided inside the annular groove 14. The sealing ring 15 is located at the lower end of the mold body 5. Rotary seats 16 are connected to the left and right sides of the top of the mounting plate 4. A rotating rod 17 is connected to the top of the rotating seat 16. A rotating plate 18 is connected to the top of the rotating rod 17. A threaded seat 19 is connected to the inner side of the top of the rotating plate 18. A threaded rod 20 is threadedly connected inside the threaded seat 19. A knob 21 is connected to the upper end of the threaded rod 20, and a pressing plate 22 is connected to the lower end of the threaded rod 20. The groove 14 facilitates the installation of the sealing ring 15. The mold body 5 is placed on the mounting plate 4, and then the rotating plate 18 is rotated to the upper end of the mold body 5 via the rotating seat 16. The knob 21 is turned, and the knob 21 drives the threaded rod 20 to rotate. The threaded rod 20 is acted upon by the thread of the threaded seat 19, which drives the pressing plate 22 to move downward. The pressing plate 22 can then press against the mold body 5, and the mold body 5 can then press against the sealing ring 15. The sealing ring 15 can then seal the moisture in the cooling box 6, preventing moisture from overflowing.

[0025] Please see Figures 1-2 In this embodiment, a water inlet pipe 23 is provided at the upper back of the water tank 7, and a drain pipe 24 is provided at the lower back of the water tank 7. A control panel 25 is installed on the right side of the front of the smelting device 1. The control panel 25 is electrically connected to the water pump 8. The drain pipe 24 facilitates the drainage of the water tank 7, and the water inlet pipe 23 facilitates the filling of the water tank 7. After the water in the water tank 7 has been used for a long time, the water can be replaced through the water inlet pipe 23 and the drain pipe 24. The control panel 25 can control the water pump 8.

[0026] During operation, the mold body 5 is placed on the mounting plate 4. Then, the rotating plate 18 is rotated to the upper end of the mold body 5 via the rotating seat 16. The knob 21 is turned, causing the threaded rod 20 to rotate. The threaded rod 20, acted upon by the threaded seat 19, moves the pressing plate 22 downwards. The pressing plate 22 then presses against the mold body 5, which in turn presses against the sealing ring 15. The sealing ring 15 seals the moisture in the cooling box 6, preventing moisture leakage. After the mold body 5 is fixed in place, the melting device 1 can be started to melt and cast the copper alloy. After the copper alloy casting is completed... The water pump 8 is started, and the water pump 8 can transport the water inside the water tank 7 to the cooling box 6 through the water suction pipe 9 and the water outlet pipe 10. After passing through the mold body 5, the water flows back to the inside of the water tank 7 through the return pipe 11, thus forming a circulation. The water can quickly carry away the heat of the mold body 5, so that the copper alloy can be cooled and solidified quickly. When the water in the return pipe 11 passes through the mounting shell 12, the cooling fans 13 on the front and rear sides are aligned, and the cooling fans 13 can cool the water in the return pipe 11. The cooled water can then flow back to the inside of the water tank 7, ensuring the efficiency of subsequent cooling of the copper alloy.

[0027] Through the above steps, by setting up a cooling box 6, a water tank 7, a water pump 8, a mounting shell 12, and a cooling fan 13, and starting the water pump 8, the water pump 8 can transport the water inside the water tank 7 to the cooling box 6 through the water suction pipe 9 and the water outlet pipe 10. The water can carry away the heat of the mold body 5 and flow to the mounting shell 12 through the return pipe 11. After being cooled by the cooling fan 13, it flows back to the water tank 7, thus forming a circulation. This can play a role in the rapid cooling and solidification of copper alloys, which solves the problem that some existing copper alloys are melted and cast by pouring the molten metal in the crucible into the mold for casting. After casting, the end cover is opened for natural cooling. However, natural cooling is slow and uneven, which may lead to a decrease in the quality of the copper alloy.
