Description

Technical Field

[0001] This invention relates to the field of copper tube processing equipment technology, specifically to a fully automatic integrated preparation device for refining and shaping copper tube materials. Background Technology

[0002] Grain refinement refers to a treatment method to improve the properties of materials, thereby enhancing their toughness and strength. Chinese Patent Publication No. CN212238643U discloses a fully automated integrated preparation device for grain refinement and forming of metallic materials, including an automated rotation system, an automated mold changing system, an extrusion forming system, and an automated mold locking device. The extrusion forming system is located at one end of the automated rotation system, the automated mold locking device is located on one side of the extrusion forming system, and the automated mold changing system is located at the bottom of the extrusion forming system. This device allows for grain refinement and improved toughness in metals previously only suitable for casting, enabling one-time extrusion forming. The fully automated process can complete a series of processing steps in a very short time, with minimal drop in material temperature, eliminating the need for reheating and heat preservation. This saves time, increases efficiency, conserves energy, and allows for the production of high-strength workpieces that were previously impossible to process through plastic forming.

[0003] In existing technologies, the fully automatic integrated preparation device for refining and forming copper tube materials involves using an electromagnetically stirred and vibrated copper tube to refine the grains before inserting it into a hollow ball mill sleeve. The rotating hollow ball mill sleeve and the intermittent tapping of the rubber block further refine the inner diameter of the copper tube, eliminating defects. However, because the connection between the rubber plate and the connecting shaft is via a nut, replacing the rubber plate after prolonged tapping requires specialized tools, making it inconvenient. Furthermore, the connection between the connecting shaft and the rotating spindle is fixed, preventing adjustment of the distance between them. When the outer diameter of the copper tube is too large, the rotating spindle causes the connecting shaft to rotate, contacting and impacting the copper tube, potentially damaging it or the equipment. This compromises the safety and applicability of the equipment. Therefore, a fully automatic integrated preparation device for refining and forming copper tube materials is proposed to meet these needs. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an integrated preparation device for fully automatic copper tube material grain refinement and forming. It features convenient adjustment of the rubber block position according to different copper tube outer diameters, increasing ease of use and facilitating rubber block replacement. This solves the problems of inconvenient use where the connection between the rubber plate and the connecting shaft is via a nut, requiring specialized tools for replacement when the rubber plate ages or is damaged due to prolonged impact; and the fixed connection between the connecting shaft and the rotating spindle, preventing adjustment of the distance between them. Furthermore, when the outer diameter of the copper tube is too large, the rotating spindle causes the connecting shaft to rotate, contacting and impacting the copper tube, resulting in damage to the copper tube or the equipment.

[0005] (II) Technical Solution To achieve the goal of facilitating the adjustment of the rubber block position according to different copper tube outer diameters, thereby increasing the ease of use of the equipment and making it easier to replace the rubber block, the present invention provides the following technical solution: A fully automated integrated preparation device for copper tube material grain refinement and forming includes a main body with a top cover, a hollow ball mill sleeve and a rotating spindle mounted on the main body, a rubber plate mounted on the rotating spindle, and a telescopic mechanism for adjusting according to the outer diameter of the copper tube mounted on the rotating spindle. The telescopic mechanism is connected to a clamping mechanism for rotating and changing components, which contacts the hollow ball mill sleeve. A collection mechanism for suction and collecting grinding debris is mounted on the main body. When the main body is in use, the copper tube is fitted onto the hollow ball mill sleeve and rotated... The rotation of the main shaft drives the rubber plate to rotate. When the rubber plate comes into contact with the copper tube during rotation, it strikes the copper tube and then contacts the hollow ball mill sleeve, thus facilitating the repair of defects in the inner diameter of the copper tube and achieving grain refinement. During this process, the distance between the rubber plate and the rotating main shaft can be adjusted by the telescopic mechanism when grinding copper tubes of different sizes, so that the rubber plate always strikes the copper tube during the rotation of the main shaft, ensuring the inner diameter repair process of the copper tube. In addition, when the rubber plate needs to be replaced or maintained, it can be done by loosening the clamping mechanism, which improves the ease of use of the equipment.

[0006] Preferably, the telescopic mechanism includes a connecting shaft seat, which is mounted on the rotating main shaft. A telescopic shaft plate is slidably mounted on the connecting shaft seat. The connecting shaft seat has a sliding groove and multiple locking holes, which are in contact with the sliding groove. A locking block is movably mounted in one of the locking holes. A sliding shaft is mounted on the locking block. The sliding groove is adapted to the sliding shaft. A limit block is mounted on the sliding shaft. The sliding shaft and the limit block are slidably mounted on the telescopic shaft plate. The telescopic mechanism refers to the mechanism where, when it is necessary to adjust the distance between the rubber plate and the rotating main shaft, pulling the locking block causes the sliding shaft and the limit block to slide on the telescopic shaft plate. After the locking block disengages from the locking hole, the sliding shaft slides in the sliding groove, causing the telescopic shaft plate to slide on the connecting shaft seat. After sliding to the appropriate position, the locking block is released, and the locking block automatically falls into the locking hole to complete the fixation of the mechanism, thereby facilitating the adjustment of the distance between the rubber plate and the rotating main shaft.

[0007] Preferably, the telescopic shaft plate has a sliding hole, and the sliding shaft is slidably installed in the sliding hole. The sliding hole restricts the movement of the sliding shaft, and the sliding shaft can only slide within the sliding hole.

[0008] Preferably, the telescopic shaft plate has a sliding cavity, and the limiting block is slidably installed in the sliding cavity. The sliding cavity is in contact with the sliding hole, and the sliding cavity restricts the movement of the limiting block. The limiting block can only slide in the sliding cavity.

[0009] Preferably, a compression spring is movably sleeved on the sliding shaft. One end of the compression spring is mounted on the limiting block, and the other end of the compression spring is mounted on the telescopic shaft plate. By setting the compression spring, when the locking block is released, the limiting block is driven to slide back to its original position under the reset action of the compression spring, thereby causing the locking block to automatically fall into the locking hole to complete the fixation, thus improving the automation level of the structure.

[0010] Preferably, the clamping mechanism includes a threaded rod, a rotating hole on a telescopic shaft plate, the threaded rod being rotatably installed in the rotating hole, a limiting groove on the telescopic shaft plate, a sliding block being slidably installed in the limiting groove, the sliding block being threaded onto the threaded rod, a clamping block being installed on the sliding block, the clamping block contacting the rubber plate, and a rotating screw block being installed on the threaded rod, the rotating screw block contacting the telescopic shaft plate. The clamping mechanism refers to the mechanism where, when the rubber plate needs to be replaced or maintained, rotating the rotating screw block causes the threaded rod to rotate within the rotating hole, thereby causing the sliding blocks to move away from each other, thus causing the clamping block to loosen the rubber plate. For reinstallation, rotating the rotating screw block in the opposite direction allows the rubber plate to be installed.

[0011] Preferably, the sliding block has a threaded hole, and the threaded rod is threaded into the threaded hole. By setting the threaded hole, the sliding block can be driven to slide in a direction away from or close to each other when the threaded rod rotates. It should be noted that the threaded holes on the two sliding blocks are in opposite directions.

[0012] Preferably, the collection mechanism includes an air inlet located on the top cover and adapted to the hollow ball mill sleeve. A connecting pipe is installed on the air inlet, and a collection box is installed on the connecting pipe. The collection box is installed on the top cover and has a connecting hole. The connecting pipe is installed in the connecting hole, and a fan is installed on the collection box. The fan is located on the top side of the connecting pipe. The working principle of the collection mechanism is that when the top cover is closed, the fan is started, and the grinding debris generated in the hollow ball mill sleeve flows through the air inlet, through the connecting pipe, and into the collection box to complete the collection process, which facilitates the continuous grain refinement and repair process.

[0013] Preferably, a limiting cover is installed on the top cover, with the air intake located inside the limiting cover. The limiting cover is adapted to the hollow ball mill sleeve. By setting the limiting cover, when the top cover is placed on the main body of the equipment, the limiting cover exactly covers the hollow ball mill sleeve, ensuring a tight connection between the connecting pipe and the hollow ball mill sleeve, while restricting the movement of the copper pipe. Preferably, a movable cover is movably installed on the collection box. The movable cover is located on one side of the connecting pipe. The movable cover facilitates the cleaning of the abrasive debris collected in the collection box, further improving the ease of use of the structure.

[0014] Compared with the prior art, the present invention provides an integrated preparation device for fully automated copper tube material grain refinement and forming, which has the following beneficial effects: 1. This invention, through the setting of a telescopic mechanism, enables the adjustment of the distance between the rubber block and the rotating spindle according to the outer diameter of the copper tube when grinding and repairing defects on the inner diameter surface of the copper tube to further refine the grains. This ensures that the copper tube is always being patted by the rubber plate during the rotation of the hollow ball mill sleeve, ensuring the safety of the equipment and facilitating the treatment of defects on the inner diameter surface of copper tubes of different sizes, thereby improving the wide applicability of the equipment.

[0015] 2. By setting up a clamping mechanism, the rubber sheet can be replaced while ensuring its normal operation. When the rubber sheet needs to be replaced, the clamping blocks can be moved away from each other by rotating the screw block to slide and release the rubber sheet, thus improving the ease of use of the structure.

[0016] 3. By setting up a collection mechanism, during the rotation of the hollow ball mill sleeve, the defective grinding debris on the inner diameter of the copper tube flows through the cavity of the hollow ball mill sleeve, passes through the connecting pipe, and enters the collection box for collection. This facilitates the continuous grinding process. At the same time, the setting of the bottom movable box facilitates the cleaning of grinding debris, further improving the practicality of the structure. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1-6A fully automated integrated preparation device for refining and forming copper tube materials includes a main body 1, a top cover 8 mounted on the main body 1, a hollow ball mill sleeve 2 and a rotating spindle 3 mounted on the main body 1, a rubber plate 4 mounted on the rotating spindle 3, a telescopic mechanism 5 for adjusting according to the outer diameter of the copper tube mounted on the rotating spindle 3, a clamping mechanism 6 for rotating and changing components connected to the telescopic mechanism 5, the clamping mechanism 6 contacting the hollow ball mill sleeve 2, and a collection mechanism 7 for suction and collecting grinding debris mounted on the main body 1. When the main body 1 is in use, the copper tube is fitted onto the hollow ball mill sleeve 2. The rotating spindle 3 drives the rubber plate 4 to rotate. When the rubber plate 4 comes into contact with the copper tube during rotation, it strikes the copper tube and contacts the hollow ball mill sleeve 2, thus facilitating the repair of defects in the inner diameter of the copper tube and achieving grain refinement. During this process, the telescopic mechanism 5 adjusts the distance between the rubber plate 4 and the rotating spindle 3 when grinding copper tubes of different sizes, ensuring that the rubber plate 4 always strikes the copper tube during the rotation of the rotating spindle 3, thus ensuring the inner diameter repair process of the copper tube. In addition, when the rubber plate 4 needs to be replaced or maintained, it can be done by loosening the clamping mechanism 6, which improves the ease of use of the equipment.

[0021] Reference Figure 1-3 In this invention, the telescopic mechanism 5 includes a connecting shaft seat 501, which is mounted on the rotating main shaft 3. A telescopic shaft plate 502 is slidably mounted on the connecting shaft seat 501. The connecting shaft seat 501 has a sliding groove 503 and multiple locking holes 504, which are in contact with the sliding groove 503. A locking block 505 is movably mounted in one of the locking holes 504. A sliding shaft 506 is mounted on the locking block 505. The sliding groove 503 is adapted to the sliding shaft 506. A limiting block 507 is mounted on the sliding shaft 506. The sliding shaft 506 and the limiting block 507 are slidably mounted. Mounted on the telescopic shaft plate 502, the telescopic mechanism 5 refers to the mechanism that, when it is necessary to adjust the distance between the rubber plate 4 and the rotating main shaft 3, pull the locking block 505 to drive the sliding shaft 506 and the limiting block 507 to slide on the telescopic shaft plate 502. After the locking block 505 disengages from the locking hole 504, the sliding shaft 506 slides in the sliding groove 503, causing the telescopic shaft plate 502 to slide on the connecting shaft seat 501. After sliding to the appropriate position, release the locking block 505, and the locking block 505 will automatically fall into the locking hole 504 to complete the fixation of the mechanism, thereby facilitating the adjustment of the distance between the rubber plate 4 and the rotating main shaft 3.

[0022] Reference Figure 1-3 In this invention, a sliding hole 508 is provided on the telescopic shaft plate 502, and the sliding shaft 506 is slidably installed in the sliding hole 508. The sliding hole 508 restricts the movement of the sliding shaft 506, and the sliding shaft 506 can only slide within the sliding hole 508.

[0023] Reference Figure 1-3In this invention, a sliding cavity 509 is provided on the telescopic shaft plate 502, and a limiting block 507 is slidably installed in the sliding cavity 509. The sliding cavity 509 is in contact with the sliding hole 508. The sliding cavity 509 restricts the movement of the limiting block 507, and the limiting block 507 can only slide within the sliding cavity 509.

[0024] Reference Figure 1-3 In this invention, a compression spring 510 is movably sleeved on the sliding shaft 506. One end of the compression spring 510 is installed on the limiting block 507, and the other end of the compression spring 510 is installed on the telescopic shaft plate 502. By setting the compression spring 510, when the locking block 505 is released, the limiting block 507 is driven to slide back to its original position under the reset action of the compression spring 510, thereby causing the locking block 505 to automatically fall into the locking hole 504 to complete the fixation, thus improving the automation level of the structure.

[0025] Reference Figure 1-4 In this invention, the clamping mechanism 6 includes a threaded rod 601, a rotating hole 602 on a telescopic shaft plate 502, the threaded rod 601 being rotatably installed in the rotating hole 602, a limiting groove 603 on the telescopic shaft plate 502, a sliding block 604 being slidably installed in the limiting groove 603, the sliding block 604 being threaded onto the threaded rod 601, a clamping block 605 being installed on the sliding block 604, the clamping block 605 being in contact with the rubber plate 4, and a rotating screw block 607 being installed on the threaded rod 601, the rotating screw block 607 being in contact with the telescopic shaft plate 502. The clamping mechanism 6 refers to the mechanism that when the rubber plate 4 needs to be replaced or maintained, rotating the rotating screw block 607 causes the threaded rod 601 to rotate in the rotating hole 602, thereby causing the sliding blocks 604 to slide away from each other, thereby causing the clamping block 605 to loosen the rubber plate 4. When reinstalling, rotating the rotating screw block 607 in the opposite direction can realize the installation of the rubber plate 4.

[0026] Reference Figure 1-4 In this invention, the sliding block 604 is provided with a threaded hole 606, and the threaded rod 601 is threadedly installed in the threaded hole 606. By setting the threaded hole 606, the sliding block 604 is driven to slide in a direction away from or close to each other when the threaded rod 601 rotates. It should be noted that the threaded holes 606 on the two sliding blocks 604 are in opposite directions.

[0027] Reference Figure 1-6In this invention, the collection mechanism 7 includes an air inlet 701, which is located on the top cover 8 and is adapted to the hollow ball mill sleeve 2. A connecting pipe 702 is installed on the air inlet 701, and a collection box 703 is installed on the connecting pipe 702. The collection box 703 is installed on the top cover 8 and has a connecting hole 704. The connecting pipe 702 is installed in the connecting hole 704, and a fan 705 is installed on the collection box 703. The fan 705 is located on the top side of the connecting pipe 702. The working principle of the collection mechanism 7 is that when the top cover 8 is closed, the fan 705 is started, and the grinding debris generated in the hollow ball mill sleeve 2 flows through the air inlet 701, through the connecting pipe 702, and into the collection box 703 to complete the collection process, which facilitates the continuous grain refinement and repair process.

[0028] Reference Figure 1-6 In this invention, a limiting cover 706 is installed on the top cover 8, and the air intake 701 is located inside the limiting cover 706. The limiting cover 706 is adapted to the hollow ball mill sleeve 2. By setting the limiting cover 706, when the top cover 8 covers the main body 1 of the equipment, the limiting cover 706 just covers the hollow ball mill sleeve 2, ensuring a tight connection between the connecting pipe 702 and the hollow ball mill sleeve 2, while restricting the movement of the copper pipe.

[0029] Reference Figure 1-6 In this invention, a movable cover 707 is movably installed on the collection box 703. The movable cover 707 is located on one side of the connecting pipe 702. The movable cover 707 facilitates the cleaning of the grinding debris collected in the collection box 703, further improving the ease of use of the structure.

[0030] When the main body 1 of the equipment is in use, the copper tube is fitted onto the hollow ball mill sleeve 2. The rotating spindle 3 drives the rubber plate 4 to rotate. When the rubber plate 4 rotates and comes into contact with the copper tube, it taps the copper tube against the hollow ball mill sleeve 2, thus facilitating the repair of defects in the inner diameter of the copper tube and achieving grain refinement. During this process, the telescopic mechanism 5 adjusts the distance between the rubber plate 4 and the rotating spindle 3 when grinding copper tubes of different sizes, ensuring that the rubber plate 4 always taps the copper tube during the rotation of the spindle 3, guaranteeing the inner diameter repair process of the copper tube. In addition, when the rubber plate 4 needs to be replaced or maintained, it can be done by loosening the clamping mechanism 6, improving the ease of use of the equipment. The telescopic mechanism 5 refers to the mechanism that adjusts the distance between the rubber plate 4 and the rotating spindle 3 when necessary. When the distance is reached, pulling the locking block 505 causes the sliding shaft 506 and the limiting block 507 to slide on the telescopic shaft plate 502, so that the locking block 505 disengages from the locking hole 504. Then, the sliding shaft 506 slides in the sliding groove 503, causing the telescopic shaft plate 502 to slide on the connecting shaft seat 501. After sliding to the appropriate position, the locking block 505 is released, and it automatically falls into the locking hole 504, completing the fixation of the mechanism. This facilitates adjusting the distance between the rubber plate 4 and the rotating main shaft 3. The sliding hole 508 restricts the movement of the sliding shaft 506, which can only slide within the sliding hole 508. The sliding cavity 509 restricts the movement of the limiting block 507, which can only slide within the sliding cavity 509. This is achieved by compressing the spring 510. The mechanism is designed so that when the locking block 505 is released, the limiting block 507 slides back to its original position under the reset action of the compression spring 510, thereby causing the locking block 505 to automatically fall into the locking hole 504 for fixing, thus improving the automation level of the structure. The clamping mechanism 6 refers to the mechanism used when the rubber plate 4 needs to be replaced or maintained. By rotating the rotating screw block 607, the threaded rod 601 rotates within the rotating hole 602, causing the sliding blocks 604 to slide away from each other, thereby causing the clamping block 605 to release the rubber plate 4. For reinstallation, rotating the rotating screw block 607 in the opposite direction allows the rubber plate 4 to be installed. The threaded hole 606 allows the sliding blocks 604 to slide in directions away from or closer to each other when the threaded rod 601 rotates. It should be noted that the threaded holes 606 on the two sliding blocks 604 are in opposite directions. The working principle of the collecting mechanism 7 is that when the top cover 8 is closed, the fan 705 is started, and the grinding debris generated in the hollow ball mill sleeve 2 flows through the suction port 701, through the connecting pipe 702, and into the collecting box 703 to complete the collection process, which facilitates the continuous grain refinement and repair process. The setting of the limiting cover 706 ensures that when the top cover 8 is on the main body 1, the limiting cover 706 is exactly on the hollow ball mill sleeve 2, ensuring a tight connection between the connecting pipe 702 and the hollow ball mill sleeve 2, while restricting the movement of the copper pipe. The setting of the movable cover 707 facilitates the cleaning of the grinding debris collected in the collecting box 703, further improving the ease of use of the structure.
