Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a device, method and storage medium for casting copper tubes or aluminum tubes. Background Art

[0002] In the field of metal pipe manufacturing, copper tubes and aluminum tubes are widely used in many industries such as refrigeration, power transmission, and building decoration due to their excellent thermal conductivity, electrical conductivity, and relatively light mass. At present, for the manufacturing of copper tubes or aluminum tubes in the industry, the two traditional methods of continuous casting and rolling and hot extrusion are generally adopted.

[0003] The continuous casting and rolling process is to continuously cast the liquid metal into a billet and then immediately perform rolling deformation to obtain the tubes of the required specifications. Although this method realizes the continuity of the production process to a certain extent and improves the production efficiency, it has many significant disadvantages. From the perspective of equipment investment, the continuous casting and rolling production line needs to be equipped with many complex and expensive equipment such as large furnaces, continuous casters, and rolling mills. The upfront capital investment is extremely huge, which poses an insurmountable financial threshold for many small and medium-sized enterprises and restricts their entry into this production field. In terms of floor area, the continuous casting and rolling production line usually requires a large area of factory buildings to arrange various equipment and reserve sufficient space for material storage, transportation, and equipment maintenance and operation, resulting in a large factory floor area and increasing the enterprise's land cost and construction cost. Moreover, the production process of continuous casting and rolling is relatively long. From the melting, casting, rolling of raw materials to subsequent finishing and other links, each step requires precise control. Any problem in any link may affect the quality of the final product, which not only increases the difficulty of production management but also makes the production cycle relatively long and difficult to quickly respond to the market's demand for product diversification and rapid delivery. The hot extrusion process is to apply pressure to the heated metal billet to make it pass through a die with a specific shape to obtain tubes with the required cross-sectional shape and size. The hot extrusion method also faces the problems of huge investment and large floor area. Hot extrusion equipment usually has a large tonnage and a complex structure, and the equipment purchase cost is high. In addition, auxiliary equipment such as heating furnaces and die change devices need to be equipped, further increasing the equipment investment. Moreover, hot extrusion production requires a large operating space to place equipment, load and unload billets, and collect products, etc., resulting in a large floor area. In the production process, hot extrusion needs to first heat the metal billet to an appropriate temperature and then perform extrusion operations. Subsequent annealing, straightening and other processing procedures may also be required. The production process is relatively cumbersome, and the production efficiency is limited to a certain extent. It is also more suitable for large-scale production models.

[0004] With the continuous change of market demand, customers' requirements for the specifications, quality, and delivery time of copper or aluminum tube products are becoming increasingly diverse. Due to inherent defects such as large investment, extensive land occupation, and long production processes, traditional continuous casting and rolling and hot extrusion methods are difficult to meet the production mode of small batches, multiple varieties, and rapid response to market demand. Summary of the Invention

[0046] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0047] Embodiment 1

[0048] As Figure 1 shown, a device for casting copper or aluminum pipes, the device includes:

[0049] Mounting seat 1; the mounting seat 1 is a mounting plate, which is a metal plate with a cuboid structure in this embodiment and is installed at the bottom of the concrete floor slab during use.

[0050] Driver 2, arranged on the mounting seat 1; in this embodiment, the driver 2 is a cylinder, which is vertically installed at the bottom of the mounting seat 1 by screws, and its output shaft faces downward.

[0051] Mold center sleeve 3, arranged on the output shaft of the driver 2 and moving synchronously with the output shaft of the driver 2;

[0052] As Figure 1 、 5, as shown in Figures 6 and 7, the die center sleeve 3 is installed in the die outer sleeve 4, which includes a first sleeve 301, a plug 302 and a second sleeve 303. The first sleeve 301 is fixedly connected to the output shaft of the driver 2, the plug 302 is fixedly connected to the bottom of the first sleeve 301, and the second sleeve 303 is connected to the first sleeve 301 through the plug 302 and is placed inside the die outer sleeve 4. This design of the die center sleeve 3 enables the die center sleeve 3 to move up and down along the output shaft direction under the drive of the driver 2, and then control the connection and disconnection between the die outer sleeve 4 and the smelting and casting furnace 5 through the plug 302, so as to realize the injection of copper liquid or aluminum liquid and the discharge of copper solution or aluminum solution in the die outer sleeve 4. The second sleeve 303 is movably placed inside the die outer sleeve 4, and the outer diameter of the second sleeve 303 is smaller than the inner diameter of the die outer sleeve 4 (the difference between the outer diameter of the second sleeve 303 and the inner diameter of the die outer sleeve 4 is the wall thickness of the copper pipe or aluminum pipe). The second sleeve 303 can move up and down inside the die outer sleeve 4 following the first sleeve 301. Since the second sleeve 303 is movably placed inside the die outer sleeve 4, when the driver 2 drives the first sleeve 301 to move upward and the plug 302 is separated from the connection port 12, at this time the second sleeve 303 also moves upward, and then the copper solution or aluminum solution enters into the die outer sleeve 4 through the connection port 12 on the smelting and casting furnace 5, that is, between the second sleeve 303 and the die outer sleeve 4.

[0053] The die outer sleeve 4 is sleeved on the die center sleeve 3, communicates with the smelting and casting furnace 5, and the connection and disconnection between the die outer sleeve 4 and the smelting and casting furnace 5 are controlled through the die center sleeve 3;

[0054] As Figure 1 , 5 , 6 and 7 show that the die outer sleeve 4 is used to match the die center sleeve 3, and its specific structure is as Figure 7 shown. When in use, a circulation channel for the copper solution or aluminum solution is formed through the gap between the inner wall of the die outer sleeve 4 and the outer wall of the second sleeve 303. An opening is provided at the bottom of the die outer sleeve 4, and this opening is used for the copper solution or aluminum solution to be pulled out of the die outer sleeve 4 by the traction rod 8 after solidifying into a pipe body inside the die outer sleeve 4. The smelting and casting furnace 5 in this embodiment includes two melting furnaces, both of which are used for melting raw material copper or raw material aluminum. The two melting furnaces are located on the left and right sides of the die outer sleeve 4, and both are provided with connection ports 12. The connection ports 12 of the two melting furnaces are on the same horizontal line and are oppositely arranged, and are uniformly connected and disconnected through the plug 302.

[0055] The crystallizer 6 is arranged on the die outer sleeve 4 and is used for preliminarily cooling the copper solution or aluminum solution in the die outer sleeve 4;

[0056] As Figure 1As shown, the crystallizer 6 of this embodiment is installed on the die outer sleeve 4 and is used to preliminarily cool the copper solution or aluminum solution so that it begins to solidify to form a preliminary copper pipe or aluminum pipe shape. The design of the crystallizer 6 can effectively control the cooling rate to ensure that a uniform pipe wall structure is formed during the solidification of the copper solution or aluminum solution.

[0057] The traction rod 8 is arranged at the bottom of the die outer sleeve 4 and is used to adhere to the preliminarily cooled copper solution or aluminum solution.

[0058] As Figure 1 shown, the traction rod 8 is movably installed inside the bottom of the die outer sleeve 4 and its up and down movement is controlled by a traction machine 9. It is used to adhere to the preliminarily cooled copper solution or aluminum solution. As the copper solution or aluminum solution solidifies and the pipe body is formed, the traction rod 8 can firmly hold the pipe body. The material of the traction rod 8 needs to have good heat resistance and wear resistance to ensure a stable working state under high temperature and friction environments. This embodiment is made of high-temperature-resistant stainless steel material, which improves the adhesiveness and wear resistance to the copper solution or aluminum solution.

[0059] The traction machine 9 is connected to the traction rod 8 and is used to traction the traction rod 8 adhered to the copper solution or aluminum solution.

[0060] As Figure 1 shown, when the preliminarily cooled copper solution or aluminum solution adheres to the traction rod 8, the traction machine 9 starts to work. By driving the traction rod 8 to move downward, it drives the copper solution or aluminum solution adhered to it to move downward together. The driving force of the traction machine 9 needs to be strong enough to ensure that during the solidification of the copper solution or aluminum solution, it can overcome its gravity and the friction force with the inner wall of the die outer sleeve 4 and smoothly pull the pipe body out of the die outer sleeve 4. During the downward movement of the copper solution or aluminum solution, the crystallizer 6 continues to cool it so that it gradually solidifies into a copper pipe or aluminum pipe with a certain strength and hardness.

[0061] As Figure 1 、 5 As shown in FIGS. 6 and 7, during use, first evenly put the raw material copper or raw material aluminum into two melting furnaces, start the melting and casting furnace 5 to heat the raw material copper or raw material aluminum until it is completely melted to form copper liquid or aluminum liquid. At this time, the driver 2 is in the initial state, and the plug 302 of the die center sleeve 3 tightly seals the two connection ports 12 on the melting and casting furnace 5 to prevent the copper liquid or aluminum liquid from flowing into the die outer sleeve 4 when not ready.

[0062] When the copper liquid or aluminum liquid reaches the appropriate temperature and fluidity, the driver 2 starts to operate, and its output shaft pushes the mold center sleeve 3 to move upward as a whole. As the mold center sleeve 3 moves upward, the plug 302 gradually separates from the connection port 12. At this time, under the action of pressure, the copper liquid or aluminum liquid is injected into the mold outer sleeve 4 through the connection port 12 simultaneously. At this time, the crystallizer 6 preliminarily cools the copper solution or aluminum solution, and then adheres to the traction rod 8. At the same time, the tractor 9 starts to work. It drives the traction rod 8 to move downward, driving the copper solution or aluminum solution adhered to it to move downward together. During the movement, the crystallizer 6 continuously cools the copper solution or aluminum solution preliminarily, causing it to start solidifying into a preliminary shape of a copper tube or an aluminum tube. As the copper solution or aluminum solution continues to move and cool, it gradually solidifies into a copper tube or an aluminum tube with a certain strength and hardness.

[0063] When the copper tube or aluminum tube solidifies to a certain length, the cutting component 10 starts to work to cut the copper tube or aluminum tube pulled out by the traction rod 8. The cut copper tube or aluminum tube can be collected and processed as needed, while the traction rod 8 continues to move downward under the drive of the tractor 9 until it is ready for the next cutting process.

[0064] As an optional embodiment of the present invention, optionally, the driver 2, the mold center sleeve 3, the mold outer sleeve 4, the crystallizer 6, and the traction rod 8 are arranged on the same central axis.

[0065] As Figure 2 shown, this design ensures the synchronism and stability of each component during the operation of the device, improving the accuracy and efficiency of the casting process. The driving force of the driver 2 is directly transmitted to the mold center sleeve 3 through the central axis, and the mold center sleeve 3 then drives the mold outer sleeve 4, the crystallizer 6, and the traction rod 8 to start synchronously, achieving the coordination of the entire casting process. At the same time, this setting method is also beneficial to reducing the floor area of the device, making the device more compact and reasonable.

[0066] As an optional embodiment of the present invention, optionally, the smelting and casting furnace (5) includes two melting furnaces. The mold outer sleeve (4) is arranged between the two melting furnaces, and connection ports (12) are relatively arranged on both melting furnaces. The connection ports (12) cooperate with the mold center sleeve (3) to control the on-off between the mold outer sleeve (4) and the two melting furnaces.

[0067] As Figure 2As shown, connection ports 12 are provided on both melting furnaces. The mold outer sleeve 4 is connected to the two melting furnaces respectively through these two connection ports 12. During the casting process, when there is the same copper liquid or aluminum liquid in the two melting furnaces, casting can be carried out synchronously, improving the casting efficiency. At the same time, the setting of the two melting furnaces can also ensure that when one of the melting furnaces fails or needs maintenance, the other melting furnace can still continue to work, ensuring the continuity and stability of production. The setting of the two melting furnaces also makes the integrity of the cast copper tubes or aluminum tubes better and the quality more stable.

[0068] When the four raw materials added to the two melting furnaces are copper, then copper tubes are finally manufactured. If the four raw materials added to the two melting furnaces are aluminum, then aluminum tubes are finally manufactured.

[0069] As an alternative embodiment of the present invention, optionally, the mold center sleeve 3 includes:

[0070] A first sleeve 301, arranged on the driver 2;

[0071] As Figure 1 、 4 As shown in FIGS. and 6, the mold center sleeve of this embodiment is made of a high-temperature resistant and stable metal material, such as high-temperature alloy steel, to ensure its stability and durability in a high-temperature environment. The first sleeve 301, as the main supporting part of the mold center sleeve 3, is fixedly connected to the output shaft of the driver 2 to ensure that the mold center sleeve 3 can move up and down accurately and stably along the output shaft direction. The first sleeve 301 of this embodiment is of a cylindrical structure and is movably sleeved on the upper part of the mold outer sleeve 4 and can move up and down freely within the upper part of the mold outer sleeve 4.

[0072] A plug 302, arranged at the end of the first sleeve 301 and located on the connection port 12, for controlling the on-off of the connection port 12;

[0073] As Figure 6 As shown in FIG., the plug 302 of this embodiment is of a conical structure, and its longitudinal section is of a trapezoidal structure and can be fully matched with the connection port 12 on the two melting furnaces to ensure that when the mold center sleeve 3 moves upward, the plug 302 can tightly seal the connection port 12 to prevent copper liquid or aluminum liquid from flowing into the mold outer sleeve 4 when not ready. At the same time, this design of the plug 302 can also smoothly disengage from the connection port 12 when the mold center sleeve 3 moves downward, enabling the copper liquid or aluminum liquid to be smoothly injected into the mold outer sleeve 4. In addition, the material of the plug 302 also needs to have good heat resistance and wear resistance to ensure a stable working state under high-temperature and friction environments. This embodiment is made of a high-temperature resistant and relatively hard alloy material, improving its service life and stability.

[0074] The second sleeve 303 is disposed on the first sleeve 301 through a plug 302 and is disposed inside the die outer sleeve 4.

[0075] As Figure 6 shown, the second sleeve 303, the plug 302 and the first sleeve 301 are integrally formed. Such a design not only simplifies the structure of the die center sleeve 3, but also improves its overall stability and durability. The second sleeve 303 and the die outer sleeve 4 serve as the flow channels for the copper solution or the aluminum solution. The outer diameter of the second sleeve 303 matches the specifications of the copper pipe or the aluminum pipe, ensuring that the cast copper pipe or aluminum pipe has precise dimensions and a uniform wall thickness. At the same time, the gap between the outer wall of the second sleeve 303 and the inner wall of the die outer sleeve 4 is appropriate, which not only ensures the smooth flow of the copper solution or the aluminum solution, but also avoids problems such as uneven wall thickness or leakage of the copper solution or the aluminum solution caused by too large a gap.

[0076] As an alternative embodiment of the present invention, optionally, the diameter of the second sleeve 303 is smaller than the inner diameter of the die outer sleeve 4, and the diameter of the first sleeve 301 is larger than the inner diameter of the die outer sleeve 4.

[0077] As Figure 1 and 6 shown, such a design enables the second sleeve 303 to move freely inside the die outer sleeve 4, while the first sleeve 301 plays a role in stabilizing and supporting, preventing the die center sleeve 3 from shifting or shaking during the up and down movement. At the same time, the outer diameter of the first sleeve 301 is larger than the inner diameter of the bottom section of the die outer sleeve 4, and the outer diameter of the first sleeve 301 is smaller than the inner diameter of the top section of the die outer sleeve 4, which can also slightly scrape and clean the inner wall of the die outer sleeve 4 when the die center sleeve 3 moves downward, avoiding casting defects caused by the residue of the copper solution or the aluminum solution.

[0078] As an alternative embodiment of the present invention, optionally, the device further includes a cooling component 7 for cooling the copper pipe or the aluminum pipe again.

[0079] As Figure 1 shown, the cooling component 7 in this embodiment is an air-cooling device, which is installed below the die outer sleeve 4 and is in direct contact with the drawn copper pipe or aluminum pipe for quickly cooling and solidifying it. The cooling component 7 is designed with an efficient heat dissipation fan and heat sink structure, and by means of forced convection, the heat on the surface of the copper pipe or aluminum pipe is quickly taken away, thereby accelerating its cooling and solidifying process. This design not only improves the cooling efficiency of the copper pipe or aluminum pipe, but also helps to maintain the shape stability and dimensional accuracy of it. At the same time, the cooling component 7 can also adjust its cooling intensity and wind speed according to actual needs to adapt to the cooling requirements of copper pipes or aluminum pipes of different specifications and materials.

[0080] As an alternative embodiment of the present invention, optionally, the device further includes a cutting member 10 for cutting the copper or aluminum tube drawn out by the towing rod 8.

[0081] As Figure 1 shown, the cutting member 10 of this embodiment is a mechanical cutting knife, which is installed below the towing machine 9 and maintains a certain contact pressure with the drawn copper or aluminum tube. When the copper or aluminum tube solidifies to a certain length, the cutting member 10 starts to work, and the mechanical cutting knife is used to quickly and accurately cut the copper or aluminum tube. The design of the cutting member 10 adopts a high-precision cutting mechanism and a stable transmission structure, ensuring the stability and accuracy of the cutting process. At the same time, the cutting member 10 can also adjust its cutting speed and cutting pressure according to actual needs to adapt to the cutting requirements of copper or aluminum tubes of different specifications and materials. This design not only improves the cutting efficiency but also helps to maintain the flatness of the cutting surface and the accuracy of the dimensions.

[0082] Embodiment 2

[0083] As Figure 8 shown, a method for casting copper or aluminum tubes, the method includes the device for casting copper or aluminum tubes as described above;

[0084] The method further includes:

[0085] S1. Place the raw material aluminum or raw material copper in the melting and casting furnace 5 and heat it to melt to form copper liquid or aluminum liquid;

[0086] S2. Use the driver to drive the mold jacket so that the plug on the mold jacket is separated from the connection port, and the copper liquid or aluminum liquid enters the mold jacket through the connection port and adheres to the towing rod. At the same time, the towing machine drives the towing rod to move downward;

[0087] S3. The crystallizer cools the copper liquid or aluminum liquid adhering to the towing rod, so that the copper liquid or aluminum liquid is initially solidified to form a tube body of copper solution or a tube body of aluminum solution;

[0088] S4. The towing machine continues to move downward, and the initially solidified tube body of copper solution or aluminum solution is cooled again by the cooling member to solidify the tube body into a copper tube or an aluminum tube.

[0089] As Figures 1 to 4As shown, it should be noted that in step S1, the raw materials aluminum and copper are heated at high temperature in the melting and casting furnace 5 and gradually melted to form copper liquid or aluminum liquid. During this process, the heating temperature and time need to be strictly controlled to ensure that the raw materials can be completely melted and the composition of the copper liquid or aluminum liquid is uniform. In step S2, the driver 2 starts to work, and its output shaft pushes the entire mold outer sleeve 4 (or more precisely, the mold center sleeve 3, because the mold outer sleeve 4 is fixed while the mold center sleeve 3 moves under the drive of the driver 2) upward. As the mold center sleeve 3 moves upward, the plug 302 gradually separates from the connection port 12. At this time, under the action of pressure, the copper liquid or aluminum liquid is injected into the mold outer sleeve 4 through the connection port 12 simultaneously. At the same time, the tractor 9 also starts to work. It drives the traction rod 8 to move downward, providing a downward pulling force for the copper liquid or aluminum liquid that is about to enter the mold outer sleeve 4, which helps the copper liquid or aluminum liquid adhere better to the traction rod 8 and prepares for the subsequent formation of the pipe body. In step S3, when the copper liquid or aluminum liquid enters the mold outer sleeve 4, the crystallizer 6 immediately cools it preliminarily. During this process, the crystallizer 6 controls the cooling rate and cooling time to make the copper liquid or aluminum liquid start to solidify and form a preliminary copper pipe or aluminum pipe shape. It should be noted that the cooling effect of the crystallizer 6 directly affects the wall structure and quality of the copper pipe or aluminum pipe, so it must be precisely designed and controlled. In step S4, as the tractor 9 continues to move downward, the preliminarily solidified copper pipe or aluminum pipe body is pulled out of the mold outer sleeve 4 and is cooled again by the cooling component 7. During this process, the cooling component 7 quickly takes away the heat on the surface of the copper pipe or aluminum pipe through forced convection, thereby accelerating its cooling and solidification process. Finally, the copper pipe or aluminum pipe that has been cooled and solidified reaches the required strength and hardness and can be cut and collected by the cutting component 10.

[0090] As another alternative embodiment of the present invention, optionally, the method further includes:

[0091] S5. Using the cutting component 10 to cut the copper pipe or aluminum pipe pulled out by the traction rod 8.
