Description

Technical Field

[0001] The invention relates to the technical field of copper rod straightening, in particular to a five-wheel continuous casting copper rod straightening device. Background Art

[0002] With the development of the global economy and the advancement of industrial technology, the non-ferrous metal processing industry is also developing continuously. As one of the important industrial raw materials, copper is widely used in the fields of electrical, electronic, construction, transportation, etc. Among them, copper rod is an important basic material for the manufacture of wires and cables, and its quality and performance directly affect the quality of the final product.

[0003] Five-wheel continuous casting is one of the common methods for processing copper rods. By pouring molten metal into the groove on the casting wheel and sealing it with a steel belt, the molten metal is cooled and formed in the groove. As the casting wheel rotates, the formed copper rod is output at the position where the groove and the steel belt are separated, thereby realizing the continuous casting of the copper rod. Since the shape of the casting wheel is circular, the output copper rod is in an arc shape. Before subsequent cutting, stamping and other processing procedures, the copper rod needs to be straightened. The traditional straightening method is to use a roller to directly roll the arc surface of the copper rod to change the copper rod from an arc to a straight line. However, due to the limitation of the arc shape of the copper rod, cracks are easily generated on the inner side of the arc due to extrusion, which affects subsequent processing.

[0060] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0061] like Figures 1 to 4 As shown, a five-wheel continuous casting copper rod straightening device of the present invention comprises:

[0062] The conveying cylinder 100 is composed of a horizontal part and an arc part;

[0063] The shaping unit 200 is located in the arc-shaped portion of the conveying cylinder 100 and is used for extruding and leveling the copper rod;

[0064] The preliminary straightening unit 300 is located in the horizontal part of the conveying cylinder 100 and is used for performing preliminary straightening treatment on the copper rod;

[0065] The precise straightening unit 400 is located in the horizontal part of the conveying cylinder 100 and is used to precisely straighten the copper rod that has completed the preliminary straightening;

[0066] Among them, the shaping unit 200 can squeeze part of the material on the outer side of the arc of the copper rod toward the inner side of the arc, so that it can help to achieve the uniform material distribution of the material inside the copper rod, avoid the phenomenon in the traditional way that when the arc-shaped copper rod is directly straightened, the inner side of the arc will directly have cracks due to less material, and achieve uniform distribution of materials on both sides of the arc of the copper rod. Of course, for the convenience of understanding, it can also be determined that when the copper rod is straightened, there is more material on the outer side of the arc, and the material on the outer side serves as a fulcrum to stretch and break the material on the inner side of the arc. Therefore, the shaping unit in this case The shaping unit 200 is one of the important structures for realizing uniform straightening of the copper rod. The shaping unit 200 includes a plurality of rolling groups, which are distributed in an arc shape in the arc portion of the conveying cylinder 100, and the curvature of the arc distribution gradually decreases along the conveying direction of the copper rod. The rolling group is composed of two U-shaped wheels 201, and the axes of the two U-shaped wheels 201 are in an angle state, and the angle openings thereof are upward, that is, the axes of the two U-shaped wheels 201 are distributed in a V shape, and the openings of the V shape are upward, and the curvature of the inner wall of the U-shaped wheel 201 gradually decreases along the upward axis direction of the U-shaped wheel 201. The U-shaped wheel 201 is rotatably mounted on the inner wall of the arc portion of the conveying cylinder 100 through the support column 202. When the copper rod passes through the conveying cylinder 100 and passes through the conveying cylinder 100 in sequence, the opening of the arc-shaped inner wall on one side of the copper rod is tilted upward or downward, rather than horizontally to the left or right as in the traditional structure. The U-shaped wheel 201 of this shape can assist in squeezing the material on the outer side of the arc portion of the copper rod, further achieving the purpose of evenly distributing the copper rod. The U-shaped wheel 201 is rotatably mounted on the inner wall of the arc portion of the conveying cylinder 100 through the support column 202. When the copper rod passes through the conveying cylinder 100 and passes through the conveying cylinder 100 in sequence, the opening of the arc-shaped inner wall on one side of the copper rod is tilted upward or downward, rather than horizontally to the left or right as in the traditional structure. When the shaping unit 200, the preliminary straightening unit 300 and the precise straightening unit 400 are used, the copper rod is sequentially subjected to the pre-straightening treatment, the preliminary straightening treatment and the precise straightening treatment. When the copper rod passes through the gap between the two U-shaped wheels 201 in the rolling group, due to the shape of the U-shaped wheel 201, the outer side of the arc-shaped part of the copper rod can be deformed toward the inner side of the arc-shaped part, that is, part of the material on the outer side of the copper rod moves toward its inner side, thereby achieving the material leveling of the copper rod, which is convenient for the copper rod to have enough material inside to allow it to deform during subsequent straightening, thereby avoiding the generation of cracks;During the rolling process of the copper rod by the U-shaped wheel 201, since the multiple rolling groups are distributed in an arc shape and their curvature gradually decreases, the multiple rolling groups can gradually transform the copper rod from an arc shape to a straight shape during the rolling process. This step can be defined as a pre-straightening treatment. The copper rod will not produce cracks during the deformation process. The copper rod processed by the shaping unit 200 will be transported to the position of the preliminary straightening unit 300 and undergo a preliminary straightening treatment. During this process, the straightness of the copper rod is improved, and its shape gradually transforms into a cylindrical shape. The density at different positions on the cross section of the copper rod is more uniform. When the copper rod passes through the position of the precise straightening unit 400, the precise straightening unit 400 performs precise straightening processing on the residual small variable bending position on the copper rod. When the copper rod is output to the outside of the conveying cylinder 100, the copper rod completes the straightening work. By adopting the above straightening method, when the copper rod is deformed, there is enough material inside to allow it to deform, thereby avoiding cracks on the inside of the copper rod when it is deformed, improving the quality of the copper rod, and through multi-step straightening processing, the straightness of the copper rod can be improved, making it convenient to make the density of different positions on the copper rod more uniform, which is convenient for subsequent processing. ;

[0067] Since the cross-sectional shape of the copper rod is irregular when it is processed by the shaping unit 200, in order to make the copper rod cylindrical and improve the straightness of the copper rod, the copper rod needs to be specially straightened. Specifically, Figures 5 and 6 As shown, the preliminary straightening unit 300 comprises:

[0068] The first rotating ring 301 is rotatably mounted on the inner wall of the conveying cylinder 100;

[0069] A plurality of support shafts 302 are distributed in an annular shape on the first rotating ring 301, and a connecting arm 303 is fixed on each support shaft 302. The end of the connecting arm 303 away from the support shaft 302 is rotatably provided with a rolling wheel 304 for straightening the copper rod;

[0070] Among them, multiple rolling wheels 304 are distributed in a ring shape around the axis of the first rotating ring 301. When the copper rod passes through the gaps between the multiple rolling wheels 304, the rolling wheels 304 are squeezed and contacted with the outer wall of the copper rod. At this time, the first rotating ring 301 is rotated, and the first rotating ring 301 will drive the multiple rolling wheels 304 to perform circular motion around the copper rod. At this time, the multiple rolling wheels 304 roll the outer wall of the copper rod, and the copper rod gradually deforms into a cylindrical shape, and the material inside the copper rod is more uniform. Due to the use of circular rolling, the outer wall of the copper rod can be straightened, thereby achieving comprehensive straightening of the copper rod.

[0071] During the process of the preliminary straightening unit 300 performing preliminary straightening on the copper rod, in order to facilitate the subsequent precise straightening work of the precise straightening unit 400, it is necessary to measure the position of the small deformation remaining on the copper rod, so it is necessary to further improve the structure of the preliminary straightening unit 300, such as Figure 7 As shown, the connecting arm 303 is composed of an oil chamber 305 and a movable plate 306;

[0072] The oil chamber 305 is curved in shape, one end of the oil chamber 305 is fixed on the support shaft 302, and the other end of the oil chamber 305 faces the axis direction of the first rotating ring 301. The oil chamber 305 is hollow inside and stores oil.

[0073] One end of the movable plate 306 is used to mount the rolling wheel 304, and the other end of the movable plate 306 is slidably inserted into the end of the oil chamber 305;

[0074] Among them, a pressure gauge 307 for detecting the oil pressure in the oil chamber 305 is provided on the oil chamber 305. When multiple rolling wheels 304 perform rolling and straightening processing on the copper rod at the same time, if there is a small deformation on the copper rod, then the protruding position of the small deformation will generate additional thrust on the rolling wheel 304. At this time, the oil pressure in the oil chamber 305 detected by the corresponding pressure gauge 307 will be different from the oil pressure detected by the pressure gauge 307 at other positions. In this way, the position of the small deformation remaining on the copper rod can be located, which is convenient for the subsequent precise straightening unit 400 to perform precise straightening processing on the position of the small deformation on the copper rod.

[0075] After the copper rod is straightened by the preliminary straightening unit 300, since the first rotating ring 301 on the preliminary straightening unit 300 only rotates in one direction, the rolling wheels 304 on the first rotating ring 301 only roll the copper rod in one direction of the copper rod circumference, which will cause the copper rod to twist and deform. In order to prevent this phenomenon from happening, Figure 2 As shown in the figure, the number of preliminary straightening units 300 is set to two groups, and the first rotating rings 301 on the two groups of preliminary straightening units 300 rotate in opposite directions, and the rolling wheels 304 on the two groups of first rotating rings 301 exert opposite forces on the copper rod along its circumferential direction, thereby achieving the offsetting work of the forces, ensuring that the copper rod will not be deformed in the subsequent direction along itself, thereby improving the quality of the copper rod.

[0076] like Figure 5 As shown, the preliminary straightening unit 300 further includes a synchronization ring 308, which moves laterally along the axis direction of the first rotating ring 301;

[0077] Each support shaft 302 passes through the first rotating ring 301 and the synchronous ring 308. The support shaft 302 and the first rotating ring 301 are rotatably connected to each other. The outer wall of the support shaft 302 on the side of the first rotating ring 301 facing the synchronous ring 308 is provided with a thread. The support shaft 302 and the synchronous ring 308 are threadedly connected to each other. The relative movement of the synchronous ring 308 and the first rotating ring 301 can drive multiple support shafts 302 to rotate synchronously, thereby driving multiple rolling wheels 304 to rotate synchronously. When the copper rod initially passes through the first rotating ring 301, The multiple rolling wheels 304 can be separated from each other by controlling the position of the synchronization ring 308 to avoid collision between the copper rod and the end face of the rolling wheel 304. When straightening, the synchronization ring 308 can control the multiple rolling wheels 304 to contact with the copper rod. Since the synchronization ring 308 can control the positions of the multiple rolling wheels 304, the straightening pressure of the rolling wheel 304 on the copper rod can be adjusted, and the setting of the synchronization ring 308 can ensure that the center point position of the multiple rolling wheels 304 remains unchanged, thereby achieving a centering effect on the multiple rolling wheels 304 and the copper rod.

[0078] like Figure 1 and Figure 5 As shown, the preliminary straightening unit 300 further includes:

[0079] A plurality of guide rails 309 are distributed in a ring shape around the axis of the first rotating ring 301. The length direction of the guide rails 309 is along the axis direction of the first rotating ring 301. The guide rails 309 are fixed on the inner wall of the conveying cylinder 100.

[0080] A moving ring 310 is located between the plurality of guide rails 309, and the moving ring 310 is slidably connected to the guide rails 309, and the synchronizing ring 308 is rotatably installed in the moving ring 310;

[0081] A plurality of first oil cylinders 311 are fixed on the conveying cylinder 100, and the movable end of the first oil cylinder 311 is connected to the movable ring 310. Specifically, the first oil cylinder 311 can be fixed on the outer wall of the conveying cylinder 100, and a plurality of holes are opened on the conveying cylinder 100. The positions of the holes correspond to the positions of the movable ring 310. A connecting plate is arranged at the movable end of the first oil cylinder 311, and the connecting plate is connected to the outer wall of the movable ring 310 through the hole. In this way, when the first oil cylinder 311 is extended or retracted, it will push the movable ring 310 to move synchronously, and the guide rail 309 guides the movable ring 310. The movable ring 310 synchronously drives the synchronous ring 308 to move, so as to provide power for the movement of the rolling wheel 304 and provide extrusion force for the rolling of the copper rod by the rolling wheel 304. Since the first rotating ring 301 needs to rotate, the synchronous ring 308 will rotate in the movable ring 310.

[0082] Since the position of the small deformation on the copper rod after the preliminary straightening treatment can be located at any position in the circumferential direction of the copper rod, it is necessary to enable the precise straightening unit 400 to have the straightening function for the copper rod at any position, such as Figure 8 and Fig. 9 As shown, the precision straightening unit 400 includes:

[0083] The second rotating ring 401 is rotatably mounted on the inner wall of the conveying cylinder 100. Two telescopic rods 402 are relatively arranged on the inner wall of the second rotating ring 401. The two telescopic rods 402 are collinear, and the telescopic direction of the telescopic rods 402 is along the radial direction of the second rotating ring 401.

[0084] A pressing block 403, mounted on a telescopic rod 402, is used to press the copper rod;

[0085] A support block 404 is mounted on another telescopic rod 402, and a groove is provided in the middle of the support block 404, and the groove corresponds to the pressing block 403;

[0086] Among them, when the position of the remaining small deformation on the copper rod moves to between the pressure block 403 and the support block 404, the second rotating ring 401 is rotated to make the protruding position of the small deformation face the pressure block 403, the two telescopic rods 402 are extended, the pressure block 403 squeezes the copper rod, and the support block 404 lifts the copper rod. The grooves on the pressure block 403 and the support block 404 cooperate to extrude and straighten the position of the small deformation on the copper rod, thereby realizing precise straightening of the copper rod; since the second rotating ring 401 can rotate in the conveying cylinder 100, it can perform comprehensive and precise straightening of the copper rod.

[0087] like Fig. 9 As shown, the precise straightening unit 400 further includes:

[0088] The adjusting ring 405 is rotatably mounted on the inner wall of the second rotating ring 401. Two inclined grooves 406 are provided on the adjusting ring 405. A sliding column 407 is slidably arranged in each inclined groove 406. The two sliding columns 407 are respectively connected to the movable ends of the two telescopic rods 402.

[0089] The second oil cylinder 408 is used to provide power for the rotation of the adjusting ring 405. The fixed end of the second oil cylinder 408 is rotatably mounted on the inner wall of the second rotating ring 401, and the movable end of the second oil cylinder 408 is rotatably mounted on the adjusting ring 405. When the second oil cylinder 408 is extended or retracted, it will push the adjusting ring 405 to rotate in the second rotating ring 401. Along the length direction of the inclined groove 406, the distance between the inclined groove 406 and the axis of the second rotating ring 401 gradually changes. In this way, when the adjusting ring 405 rotates, the adjusting ring 405 can push the sliding column 407 to move along the radial direction of the second rotating ring 401 through the inclined groove 406, and the telescopic rod 402 performs a telescopic movement, and the two telescopic rods 402 move synchronously, thereby keeping the midpoint position of the line between the pressing block 403 and the supporting block 404 fixed, avoiding the bending of the copper rod when the midpoint position is offset, and improving the straightening effect.

[0090] Since the copper rod is in a continuous conveying state in the precision straightening unit 400, the precision straightening unit 400 needs to move synchronously and keep relatively still with the copper rod when straightening the copper rod. Figure 8 In the structure shown, the second rotating ring 401 slides in the conveying cylinder 100, and the precise straightening unit 400 also includes:

[0091] The annular tooth groove 409 is provided on the inner wall of the second rotating ring 401. A plurality of first gears 410 are meshedly arranged in the annular tooth groove 409. The annular tooth groove 409 synchronously blocks the first gears 410.

[0092] A plurality of connecting rods 411 are respectively mounted on the plurality of first gears 410, and the cross-section of the connecting rods 411 is a prismatic shape;

[0093] A plurality of sliding sleeves 412, the sliding sleeves are arranged on the plurality of connecting rods 411, the sliding sleeves 412 are rotatably mounted on the inner wall of the conveying cylinder 100, and the sliding sleeves 412 are connected to the first gear 410 via a spring 413;

[0094] A plurality of second gears 414 are respectively mounted on the plurality of sliding sleeves 412;

[0095] The inner gear ring 415 is rotatably mounted on the inner wall of the conveying cylinder 100, and the second gear 414 is meshedly connected with the inner gear ring 415;

[0096] A first motor 416 is fixed to the inner wall of the conveying cylinder 100 and is used to provide power to a second gear 414;

[0097] The retaining edge 417 is fixed on the inner wall of the conveying cylinder 100 and is used to position the second rotating ring 401;

[0098] The inner gear ring 415 and the retaining edge 417 are respectively located on both sides of the second rotating ring 401. The spring 413 can provide an elastic thrust for the second rotating ring 401 with the help of the first gear 410 and the ring tooth groove 409, so that the second rotating ring 401 contacts the retaining edge 417. When the pressing block 403 and the supporting block 404 straighten the copper rod, due to the friction between the pressing block 403, the supporting block 404 and the copper rod, the copper rod will push the second rotating ring 401 to move horizontally. At this time, the second rotating ring 401 and the copper rod are relatively stationary, and the elastic thrust is The spring 413 undergoes elastic deformation, and the connecting rod 411 slides on the sleeve 412. By utilizing the shape characteristics of the connecting rod 411, the connecting rod 411 and the sleeve 412 can always maintain a transmission state. The first motor 416 can drive multiple second gears 414 and the inner gear ring 415 to rotate synchronously. The second gear 414 can drive the second rotating ring 401 to rotate through the sleeve 412, the connecting rod 411, the first gear 410 and the annular tooth groove 409, thereby providing power for the direction adjustment work of the pressure block 403 and the support block 404.

When the second motor 506 is running, it will drive the first bevel gear 502, the second bevel gear 503, the transmission shaft 504 and the transmission wheel 505 to move synchronously. Due to the structural setting of the first bevel gear 502 and the two second bevel gears 503, the two transmission wheels 505 can rotate synchronously in opposite directions, so that the two first rotating rings 301 in the two groups of preliminary straightening units 300 rotate synchronously in opposite directions.
