Copper castings have excellent thermal conductivity, wear resistance and corrosion resistance, so they meet the special requirements of specific industrial applications. Centrifugal casting is an important process for the production of copper castings.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1 According to an embodiment of the present invention, a technical solution is provided: a high-efficiency centrifugal casting device for copper castings, comprising a long strip component 1 arranged along a first direction, a cylindrical body 2 with openings at both ends, and three baffles. Figure 1In the figure, the first direction is the left-right direction, and the machine body 2 is movably sleeved on the outside of the long strip component 1 along the first direction and rotatable around its own axis; three baffles are fixedly arranged on the outside of the long strip component 1 at intervals along the first direction, and the three baffles include a circular middle plate 3 and two end plates 4 respectively arranged on both sides of the middle plate 3, and the gap between the outer edge of the middle plate 3 and the inner wall of the machine body 2 is matched. It can be understood that the gap between the outer edge of the middle plate 3 and the inner wall of the machine body 2 should be as small as possible, while ensuring that the middle plate 3 can slide along the first direction inside the machine body 2, the casting copper liquid inside the machine body 2 is avoided from being retained, and the two end plates 4 are both detachably fixedly connected to the long strip component 1. When the machine body 2 moves along the first direction, it can form a forming cavity 6 with an adjacent middle plate 3 and an end plate 4.

[0036] In the above scheme, when the machine body 2 moves to the left side of the long strip component 1, a relatively closed forming cavity 6 can be formed between the end plate 4 on the left and the middle plate 3. By rotating the machine body 2, the cast copper liquid is cooled in the forming cavity 6 and forms a copper tube. When it is necessary to produce the next copper tube, it is only necessary to move the machine body 2 to the right side of the long strip component 1 so that a relatively closed forming cavity 6 is formed between the machine body 2 and the end plate 4 on the right and the middle plate 3. At this time, the machine body 2 can be quickly put into the production of the next copper tube. Since the middle plate 3 will prevent the copper tube that has been formed in the forming cavity 6 from moving synchronously with the machine body 2 during the process of the machine body 2 moving to the right, the copper tube will remain on the left side of the long strip component 1, so that the copper tube can be taken out of the forming cavity 6 more conveniently, killing two birds with one stone and helping to improve production efficiency. In addition, in order to facilitate the removal of the copper tube from the long strip component 1, the two end plates 4 can be detachably fixedly connected to the long strip component 1. Preferably, the two end plates 4 can be fixed to the long strip component 1 by means of pins 5.

[0037] Example 2: See Figure 2 , the main difference from the first embodiment lies in the number of middle plates 3. In this embodiment, two middle plates 3 are provided. The two middle plates 3 and the two end plates 4 respectively form a first baffle group and a second baffle group. The machine body 2 has a first processing position and a second processing position on the long strip component 1. The molding cavity 6 is composed of a first molding cavity and a second molding cavity. When the machine body 2 is in the first processing position, its first end is enclosed with the first baffle group to form a first molding cavity. When the machine body 2 is in the second processing position, its second end is enclosed with the second baffle group to form a second molding cavity. By combining two independent middle plates 3 and two end plates 4 to form two baffle groups, the distance between the two processing positions in the first direction can be increased, so that when the operator removes the copper pipe from one of the processing positions, the heat radiation of the other processing position to the operator can be reduced.

[0038] In order to improve the airtightness between the outer edge of the middle plate 3 and the inner wall of the body 2, in this exemplary embodiment, the inner wall of the body 2 is protruded with an annular protrusion 7, and the protrusion 7 is tightly against the middle plate 3 in the first baffle group when the body 2 is in the first processing position, and the protrusion 7 is tightly against the middle plate 3 in the second baffle group when the body 2 is in the second processing position. After such arrangement, whether in the first processing position or the second processing position, the protrusion 7 can be tightly fitted with the protrusion 7 of the body 2, improving the airtightness of the molding cavity 6 to prevent the outflow of copper liquid. In order to allow the middle plate 3 to be better inserted into the body 2 from both ends of the body 2, the outer edges of the two middle plates 3 are both provided with an outer conical surface, and the protrusion 7 is provided with an inner conical surface adapted to the outer conical surface, and the middle plate 3 is fitted and tightly against the inner conical surface of the protrusion 7 through the outer conical surface, so that the middle plate 3 can be more accurately inserted into the body 2 from the openings at both ends of the body 2.

[0039] In order to reduce the resistance during the rotation of the machine body 2, in this embodiment, the end plate 4 includes a cylindrical portion 40 and an annular plate 41. The cylindrical portion 40 is slidably mounted on the elongated component 1, and the middle plate 3 and the elongated component 1, and the cylindrical portion 40 and the annular plate 41 are rotatably connected via bearings 8.

[0040] Example 3: See Figures 3 to 6 On the basis of the second embodiment, in this exemplary embodiment, the internal structure of the long strip component 1 is provided with a feeding channel, and the feeding channel connects the molding cavity 6 with the external environment. Preferably, the feeding channel includes a left feeding channel 9 connected to the first molding cavity and a right feeding channel 10 connected to the second molding cavity. A feeding nozzle 11 is rotatably connected to the long strip component 1 between the left feeding channel 9 and the right feeding channel 10. The feeding nozzle 11 has a connecting channel 39 connecting the feeding channel with the external environment, so that the connecting channel 39 is connected to the left feeding channel 9 or the right feeding channel 10 by rotating the feeding nozzle 11. In specific implementation, the feeding channel is not only convenient for introducing the external casting copper liquid into the molding cavity 6, but also can discharge the air in the molding cavity 6 during the casting process, thereby improving the quality of the copper casting. By providing a rotatable feeding nozzle 11, the feeding nozzle 11 can be selectively connected to the left feeding channel 9 or the right feeding channel 10, thereby achieving the purpose of adding casting copper liquid to the left feeding channel 9 or the right feeding channel 10 alone.

[0041] It is understandable that the above-mentioned feeding channel is not necessary. In some embodiments, a copper block can be placed in the body 2 in advance, and then the copper block in the body 2 can be heated until it melts by electromagnetic induction heating. In this way, there is no need to set up a feeding channel.

[0042] In order to realize the rotational connection between the feeding nozzle 11 and the elongated component 1, in the present embodiment, one end of the feeding nozzle 11 is configured as a spherical structure, and a connecting hole adapted to the end of the feeding nozzle 11 is provided on the elongated component 1, and the feeding nozzle 11 is rotationally matched with the connecting hole of the elongated component 1 through the spherical structure.

[0043] In order to facilitate the discharge of materials in the feeding channel, in this embodiment, the left feeding channel 9 and the right feeding channel 10 both include a straight section 12 and a tapered section 13. The straight section 12 is the same length as the molding cavity 6. The tapered section 13 connects the straight section 12 with the feeding nozzle 11. The straight section 12 is provided with an elongated liquid leakage slit 14 of the same length as the straight section 12. The casting copper liquid first enters the tapered section 13 through the feeding nozzle 11 and flows along the inclined surface of the tapered section 13. The inclined surface of the tapered section 13 can accelerate the casting copper liquid and reduce the accumulation of the casting copper liquid. When the casting copper liquid flows into the straight section 12, the elongated liquid leakage slit 14 of the straight section 12 can make the casting copper liquid uniformly discharged into the body 2, so as to ensure the uniform thickness of the produced copper tube and improve the quality of the copper tube.

[0044] In order to further prevent the casting copper liquid from accumulating in the straight section 12, in this embodiment, the long strip component 1 is made of non-metallic material (such as ceramic), and an electromagnetic induction coil 15 is wound around the outside of the long strip component 1 located in the straight section 12. The electromagnetic induction coil 15 is used to heat the casting copper liquid flowing through the straight section 12, thereby improving the fluidity of the casting copper liquid and reducing the accumulation of the casting copper liquid in the straight section 12.

[0045] In order to facilitate the rotation of the feeding nozzle 11, in this embodiment, a plurality of handles 16 are fixedly provided on the feeding nozzle 11, and the plurality of handles 16 are arranged along the circumference of the feeding nozzle 11. The feeding nozzle 11 can be rotated more labor-savingly by the handles 16.

[0046] Example 4: See Figures 3 to 6On the basis of the third embodiment, in this exemplary embodiment, the efficient centrifugal casting equipment for copper castings also includes a support assembly, which includes two support rods 17, a first screw rod 18, two nuts 19 and a linkage rod 20. The two support rods 17 are arranged between the adjacent middle plate 3 and the end plate 4 and are respectively located on both sides of the long strip component 1; the first screw rod 18 is provided with external threads with opposite rotation directions at both ends and is rotatably arranged in the feeding channel, and the first screw rod 18 is driven to rotate by a first motor 21 or other methods known to those skilled in the art; the two nuts 19 are respectively threadedly matched with the two ends of the first screw rod 18; the two nuts 19 of the linkage rod 20 are respectively connected to the two ends of the support rod 17 through a linkage rod 20, and the linkage rod 20 and the nut 19 as well as the linkage rod 20 and the support rod 17 are rotatably connected, and the long strip component 1 is provided with a sliding hole 22 for the linkage rod 20 to move. In the specific implementation, after the copper tube is formed, the first motor 21 drives the first screw rod 18 to rotate, driving the two support rods 17 to move away from each other until the two support rods 17 support the inner wall of the copper tube. At this time, the body 2 is moved to the other end of the long strip component 1, which can reduce the contact resistance between the body 2 and the copper tube, and prevent the copper tube from falling, thereby achieving stable disassembly of the copper tube.

[0047] In order to realize the movement of the body 2 along the first direction, in this exemplary embodiment, the copper casting high-efficiency centrifugal casting equipment also includes a frame 23 and a slide 24, the slide 24 is slidably connected to the frame 23 along the first direction and is used to support the body 2, and the frame 23 is provided with a first driving device for driving the slide 24 to move along the first direction. Specifically, the slide 24 is slidably connected to the frame 23 through two guide rails 25, and the first driving device includes a second motor 26 and a second screw rod 27, the second screw rod 27 is arranged along the first direction and is rotatably connected to the frame 23 through a bearing, the second screw rod 27 is threadedly matched with the slide 24, and the second motor 26 is installed on the frame 23 and is used to drive the first screw rod 18 to rotate. In the specific implementation, the second motor 26 drives the second screw rod 27 to rotate, and the second screw rod 27 drives the slide 24 and the body 2 on the slide 24 to move along the first direction. Of course, as long as the movement of the body 2 along the first direction can be realized, there is no particular restriction on the specific structural form of the first driving device.

[0048] In order to realize the rotation of the machine body 2 around its own axis, in this exemplary embodiment, a second driving device for driving the machine body 2 to rotate around its own axis is installed on the slide 24. Specifically, the second driving device includes two sets of axles arranged on both sides of the machine body 2, each set of axles includes a shaft body 28 rotatably connected to the slide 24 through a bearing 8 seat and two wheels 29 arranged at both ends of the shaft body 28, the two wheels 29 support the machine body 2 and are in rolling contact with the outer wall of the machine body 2, and a third motor 30 is installed on the slide 24, the output end of the third motor 30 is fixedly connected to a driving gear 31, and the middle part of the shaft body 28 is fixedly provided with a driven gear 32 meshing with the driving gear 31. In specific implementation, the third motor 30 drives the axle to rotate, and the axle drives the machine body 2 to rotate around itself. Of course, as long as the rotation of the machine body 2 around its own axis can be realized, there is no special restriction on the specific structural form of the second driving device.

[0049] In this exemplary embodiment, the frame 23 is provided with two end support parts for supporting the two ends of the long strip component 1, and the two end support parts are detachably connected to the frame 23. Specifically, each support part includes a support plate 33 and a first plug rod 34 and a second plug rod 35 provided on the support plate 33. Two first plug rods 34 are provided, and the frame 23 is provided with a first plug hole 36 corresponding to the two first plug rods 34; the second plug rod 35 is a multi-prism structure, and the end of the long strip component 1 is provided with a second plug hole 37 adapted to the shape of the second plug rod 35. In specific implementation, when the copper tube at the left end of the long strip component 1 needs to be disassembled, the end support part at the left end of the long strip component 1 can be disassembled to facilitate the disassembly of the copper tube. On the contrary, when the copper tube at the right end of the long strip component 1 needs to be disassembled, the end support part at the right end of the long strip component 1 can be disassembled to disassemble the copper tube.

[0050] When the end support portion at any end of the long strip component 1 is removed, all the pressure of the long strip component 1 will act on the end support portion at the other end, which is likely to cause pressure loss of the support portion. Based on this problem, in this exemplary embodiment, the copper casting high-efficiency centrifugal casting equipment also includes a middle support portion, which provides additional upward support force to the middle part of the long strip component 1 when one of the end support portions does not support the long strip component 1. Specifically, the middle support portion is a lifting ring 38 arranged in the middle of the long strip component 1, and the lifting ring 38 can be connected to the lifting equipment through a lifting rope. When the end support portion at any end of the long strip component 1 is removed, an upward pulling force can be applied to the middle support portion through the lifting equipment, thereby balancing part of the gravity of the long strip component 1 in turn, and reducing the pressure of the long strip component 1 on the end support portion at the other end.

[0051] Working principle: In the process of casting copper tubes, the first driving device is first started to move the slide 24 and the machine body 2 above it to the left side of the long strip component 1. At this time, the machine body 2, the left end plate 4 and the middle plate 3 together form the first forming cavity. Subsequently, the casting copper liquid is injected into the left feeding channel through the feeding nozzle 11, and the copper liquid flows into the first forming cavity along the channel. Then, the second driving device is started to make the machine body 2 start to rotate. Under the action of centrifugal force, the casting copper liquid is rapidly cooled in the first forming cavity and gradually forms a copper tube. After the copper tube is formed, the first driving device translates the machine body 2 to the right side of the long strip component 1 again. At this time, the machine body 2, the right end plate 4 and the middle plate 3 form the second forming cavity. In the process of the machine body 2 moving to the right, the middle plate 3 effectively prevents the already formed copper tube from moving with the body, ensuring that the copper tube remains stably on the left side of the long strip component 1. After that, use a lifting device to lift the middle part of the long strip component 1, remove the end support part on the left side, and then remove the left end plate 4, so that the formed copper tube can be easily taken out, completing the entire casting process.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
