Description

Technical Field

[0001] This invention relates to the field of CNC radial axial ring rolling machine technology, and in particular to a high-performance CNC radial axial ring rolling machine core roller dual-station mechanism and its adjustment method. Background Technology

[0002] The CNC radial axial ring rolling machine is a CNC equipment integrating mechanics, electronics, hydraulics, and instrumentation. It is mainly used for rolling forgings such as bearing rings, gear rings, flanges, wheel hubs, thin-walled barrel shapes, wind power flanges, and high-diameter flanges. The CNC radial axial ring rolling machine rolls the ring-shaped workpiece using a mandrel. The mandrel is a component that can position and compress the ring-shaped workpiece, causing it to gradually expand. The thickness of the ring-shaped workpiece can be controlled during the processing.

[0003] In existing ring rolling machines, the mandrel typically has only a single station. When processing ring-shaped workpieces of different heights, it is often necessary to change mandrels of different specifications or use shims to adjust the height of the mandrel. This adjustment method is not only cumbersome and inefficient, but frequent disassembly and assembly of the mandrel also accelerates the wear of the mandrel and its supporting structure, shortening the service life of the mandrel. To address this, some ring rolling machines have set multiple rolling zones along the axial direction of the mandrel and use hydraulic cylinders to drive the mandrel to rise and fall to switch between different stations, thus adapting to the processing needs of ring-shaped workpieces of different heights without changing the mandrel. However, the above solution still has many shortcomings in practical applications: the lack of precise guidance during the mandrel lifting process makes it difficult to ensure the coaxiality of the mandrel lifting, affecting processing accuracy; the lifting device often uses a single-sided hydraulic cylinder drive, resulting in uneven force and easily causing the mandrel to skew; the transmission method of the drive mechanism has limited precision, making it difficult to meet the requirements of CNC systems for precise control. In addition, the position locking device after the mandrel is raised and lowered can usually only achieve unidirectional limit and cannot withstand the huge radial extrusion force on the mandrel during the ring rolling process, causing the mandrel to deviate during the processing and affecting the rolling quality of the ring workpiece; and the drive mechanism is exposed to a large amount of metal chips and cutting fluid generated during the ring rolling process for a long time, which is prone to wear failure and affects the service life of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a high-performance CNC radial axial ring rolling machine core roller dual-station mechanism and its adjustment method, which can realize automated dual-station switching and precise adjustment of the core roller. It has the advantages of high precision, high stability and high reliability, and effectively solves the technical problems in the prior art, such as the inability of the core roller to be conveniently rolled in dual stations, the easy wear of the core roller and its support structure when adjusting the height, the need for frequent replacement of the core roller when processing ring workpieces of different heights, and the insufficient reliability of locking after the core roller is raised and lowered.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a high-performance CNC radial axial ring rolling machine core roller dual-station mechanism, comprising a core roller, a fixed shaft, a mounting base plate, a baffle, a cover plate, a lifting device, and a fixing device. The surface of the core roller is movably connected to the interior of the fixed shaft. The mounting base plate is movably connected to the surface of the core roller. The baffle is fixedly connected to the top of the mounting base plate, and the cover plate is fixedly connected to the top of the baffle. Movable holes are respectively provided on the mounting base plate and the cover plate. The fixed shaft drives the core roller to slide through the two movable holes to the mounting base plate and the cover plate. Lifting devices are respectively provided on the left and right sides of the top of the mounting base plate. Each lifting device includes a slider, a first support block, a lifting rod, a second support block, a gear, and a motor. Trapezoidal grooves are symmetrically provided on the mounting base plate. The slider is slidably connected to the trapezoidal grooves. One end of the slider is fixedly connected to the first support block, and the lifting rod is movably connected to the surface of the first support block. The top of the lifting rod is movably connected to the second support block, which is fixedly connected to the fixed shaft. The top of the slider is fixedly connected to multiple mating blocks, the surface of which meshes with the gear for transmission. The top of the gear is fixedly connected to the motor. The lifting device is used to drive the fixed shaft to move the core roller up and down in the vertical direction. The fixed device is provided on both the front and rear sides of the fixed shaft. The fixed device includes an L-shaped block, a locking block, a hydraulic column, and a square block. The L-shaped block is fixedly connected to the fixed shaft. The locking block is movably connected to the surface of the L-shaped block. The top of the L-shaped block is fixedly connected to a hydraulic housing. The hydraulic column is movably connected inside the hydraulic housing. The locking block is fixedly connected to the square block, which is inserted into the hydraulic column. The L-shaped block, the locking block, and the square block cooperate to form a bidirectional limit on the fixed shaft, so as to lock the fixed shaft after the core roller moves to the target height.

[0006] Furthermore, the hydraulic column is electrically connected to a first infrared sensor, and the square block has multiple circular slots inside. Each of the multiple circular slots is equipped with a second infrared sensor. When the first infrared sensor senses any of the second infrared sensors, the hydraulic column extends into the corresponding circular slot.

[0007] Furthermore, the plurality of circular grooves are evenly distributed along the height direction of the square block.

[0008] Furthermore, a protective shell is fixedly connected to the top of the motor, and the top of the protective shell is fixedly connected to the bottom of the cover plate.

[0009] Furthermore, the slider is trapezoidal in shape, and the inner wall of the trapezoidal groove is in close contact with the surface of the slider.

[0010] Furthermore, a ring is fixedly connected to the top of the core roller surface, and a groove is provided inside the fixed shaft, with the surface of the ring in close contact with the inner wall of the groove.

[0011] This invention also provides a high-performance dual-station adjustment method for CNC radial axial rolling mill core rollers, employing the aforementioned high-performance CNC radial axial rolling mill core roller dual-station mechanism, comprising the following steps: S1. Start the motor to drive the gears to rotate; S2. The gear drives the slider to slide along the trapezoidal groove through meshing with the mating block. S3. The slider drives the lifting rod to move through the first support block, and the lifting rod drives the fixed shaft to move in the vertical direction through the second support block, so that the fixed shaft drives the core roller to rise and fall synchronously. S4. When the core roller moves to the target height, the first infrared sensor inside the hydraulic column moves with the fixed shaft to be opposite to the second infrared sensor inside the corresponding circular groove on the square block. The hydraulic column extends into the corresponding circular groove and locks the fixed shaft.

[0012] Furthermore, the plurality of circular grooves are evenly distributed along the height direction of the square block, and each circular groove corresponds to a different working height of the core roller.

[0013] Compared with the prior art, the beneficial technical effects of the present invention are as follows: This invention achieves automated dual-station switching and precise height adjustment of the core roller through the rotational engagement of the core roller and the fixed shaft, the vertical sliding of the core roller along the moving holes on the mounting base plate and cover plate driven by the fixed shaft, and the coordinated operation of symmetrically arranged lifting devices on the left and right sides and fixed devices on the front and rear sides. Regarding transmission accuracy, the lifting device uses a motor-driven gear and mating block meshing transmission to drive the slider along a trapezoidal groove. The slider drives the fixed shaft through a first support block, a lifting rod, and a second support block, causing the core roller to rise and fall synchronously. Compared to traditional belt drives, the gear meshing transmission method eliminates slippage loss and transmission delay, resulting in high transmission efficiency and fast response speed, meeting the precision control requirements of CNC systems and avoiding the problem of decreased transmission accuracy caused by the loosening of traditional belts after long-term use. In terms of guiding accuracy and vibration resistance, by setting a trapezoidal groove that matches the shape of the slider and ensuring close contact between the inner wall of the trapezoidal groove and the surface of the slider, the trapezoidal structure achieves centering guidance while eliminating the mating gap during slider sliding, effectively reducing slider wobbling caused by rolling vibration. The mounting base and cover plate feature dual upper and lower movable holes that simultaneously guide the fixed shaft and mandrel, ensuring coaxiality during mandrel lifting and lowering. This prevents tilting of the mandrel during long-distance lifting and lowering, thereby improving the rolling accuracy of the ring-shaped workpiece. In contrast, existing technologies using ordinary flat grooves have clearances and cannot achieve the same level of vibration-resistant guidance. Regarding locking reliability and load-bearing capacity, the fixed shaft is equipped with fixing devices on both the front and rear sides. These devices utilize L-shaped blocks, locking blocks, and square blocks to form a bidirectional limit on the fixed shaft, simultaneously restricting both horizontal and vertical displacement. The hydraulic column provides greater driving force than traditional electric push rods, capable of withstanding the enormous radial extrusion force generated during mandrel rolling. Furthermore, the first infrared sensor within the hydraulic column and the second infrared sensors within multiple circular grooves on the square blocks automatically sense and position the mandrel, automatically locking it when it reaches the target height. This precise limiting avoids the problems of existing unidirectional insertion structures being unable to withstand large loads and the low efficiency of manual adjustment, ensuring the rolling quality of the ring-shaped workpiece.

[0014] This invention utilizes a protective shell, with its top fixedly connected to the bottom of a cover plate. This shell encloses the motor and gears, effectively preventing the large amounts of metal debris and cutting fluid generated during ring rolling from entering the drive mechanism. This avoids wear and jamming on the meshing surfaces of the gears and mating blocks due to foreign object intrusion, significantly extending the service life of the drive mechanism. Furthermore, symmetrical lifting devices are installed on the left and right sides of the top of the mounting base plate. Driven synchronously by two motors, both sides of the fixed shaft and the mandrel are simultaneously subjected to force and raised and lowered synchronously. This avoids uneven load on the fixed shaft and tilting of the mandrel caused by unilateral drive, ensuring smooth operation during mandrel lifting. The ring on the top surface of the mandrel is in close contact with the inner wall of the groove inside the fixed shaft, resulting in low frictional resistance and smooth rotation when the mandrel rotates inside the fixed shaft, reducing rotational wear and further extending the mandrel's service life.

[0015] In summary, this invention achieves high-precision, high-stability, and high-reliability automatic adjustment of the mandrel position through the synergistic effect of various structures, including gear meshing transmission, trapezoidal groove tight guidance, upper and lower double moving holes bidirectional guidance, L-shaped block bidirectional limiting, hydraulic column high-load drive, infrared sensor automatic positioning, protective shell for dust and chip prevention, and double-sided symmetrical synchronous lifting. It effectively solves the technical problems in the prior art, such as the inability of the mandrel to be conveniently used for dual-station rolling, the easy wear of the mandrel and its support structure when adjusting the height, the need for frequent replacement of the mandrel when processing ring workpieces of different heights, and the insufficient reliability of locking after the mandrel is raised or lowered.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1 like Figures 1 to 7 As shown, the high-performance CNC radial axial rolling machine core roller dual-station mechanism of this embodiment 1 includes a core roller 1 and a fixed shaft 2. The surface of the core roller 1 is movably connected to the interior of the fixed shaft 2. A mounting base plate 3 is movably connected to the surface of the core roller 1. A baffle 4 is fixedly connected to the top of the mounting base plate 3. A cover plate 5 is fixedly connected to the top of the interior of the baffle 4. The interiors of both the baffle 4 and the cover plate 5 are movably connected to the surface of the core roller 1. Lifting devices 6 are provided on the left and right sides of the top of the mounting base plate 3. Fixing devices 7 are provided on the front and rear sides of the fixed shaft 2.

[0024] Among them, such as Figure 2 and Figure 4 As shown, the lifting device 6 includes a slider 601. The surface of the slider 601 is movably connected to the right side of the mounting base plate 3. A first support block 602 is fixedly connected to the left side of the top of the slider 601. A lifting rod 603 is movably connected to the surface of the first support block 602. A second support block 604 is movably connected to the inside of the top of the lifting rod 603. The left side of the second support block 604 is fixedly connected to the right side of the fixed shaft 2. By setting up the lifting device 6, the fixed shaft 2 can be moved up and down, thereby causing the fixed shaft 2 to drive the core roller 1 to move up and down, realizing the positioning of the core roller 1 on ring-shaped workpieces of different heights.

[0025] In this embodiment, as Figure 4 As shown, a mating block 8 is fixedly connected to the top of the slider 601. Multiple mating blocks 8 are evenly distributed on the top of the slider 601. Gears 9 are in close contact with the surfaces of the multiple mating blocks 8. A motor 10 is fixedly connected to the top of the gears 9, and a protective shell 11 is fixedly connected to the top of the motor 10. The top of the protective shell 11 is fixedly connected to the bottom of the cover plate 5. By setting up the mating blocks 8, gears 9, motor 10, and protective shell 11, the motor 10 can drive the gears 9 to rotate. The cooperation between the gears 9 and the mating blocks 8 enables the fixed shaft 2 to drive the core roller 1 to adjust its height.

[0026] In addition, such as Figure 2 and Figure 6As shown, a trapezoidal groove 15 is provided at the top inside the mounting base plate 3. The slider 601 is trapezoidal in shape, and the interior of the trapezoidal groove 15 is slidably connected to the surface of the slider 601. The inner wall of the trapezoidal groove 15 is in close contact with the surface of the slider 601. By setting the trapezoidal groove 15 and making the slider 601 trapezoidal, the slider 601 can move better inside the trapezoidal groove 15, allowing the slider 601 to drive multiple mating blocks 8 to move and the lifting rod 603 to move through the trapezoidal groove 15.

[0027] like Figure 5 As shown, the fixing device 7 includes an L-shaped block 701. The rear side of the L-shaped block 701 is fixedly connected to the front side of the fixing shaft 2. A locking block 702 is movably connected to the left side of the surface of the L-shaped block 701. A hydraulic housing 703 is fixedly connected to the top left side of the L-shaped block 701. A hydraulic column 704 is movably connected inside the hydraulic housing 703. A square block 705 that cooperates with the hydraulic column 704 is fixedly connected to the left side of the locking block 702. By setting the fixing device 7, the fixing shaft 2 can be fixed to the square block 705 after the fixing shaft 2 drives the core roller 1 to move a certain height.

[0028] And, as Figure 5 As shown, a first infrared sensor 12 is electrically connected inside the hydraulic column 704. A circular groove 13 is formed inside the square block 705, and multiple circular grooves 13 are evenly distributed within the square block 705. A second infrared sensor 14 is installed inside each of the multiple circular grooves 13. By setting the first infrared sensor 12, the multiple circular grooves 13, and the second infrared sensors 14, after the first infrared sensor 12 senses the second infrared sensor 14, the first infrared sensor 12 will drive the hydraulic column 704 to move into the interior of the circular groove 13, thereby causing the fixed shaft 2 to adjust the height of the core roller 1 and then fix it in place.

[0029] At the same time, such as Figure 6 As shown, both the interior of the mounting base plate 3 and the interior of the cover plate 5 have movable holes 16. The fixed shaft 2 drives the core roller 1 to slide through the two movable holes 16 and slide into the interior of the mounting base plate 3 and the interior of the cover plate 5. By providing the movable holes 16, the height of the core roller 1 driven by the fixed shaft 2 can be adjusted vertically through the movable holes 16.

[0030] Preferred, such as Figure 7 As shown, a ring 17 is fixedly connected to the top of the surface of the core roller 1, and a groove 18 is formed inside the fixed shaft 2. The surface of the ring 17 is in close contact with the inner wall of the groove 18. By setting the ring 17 and the groove 18, the core roller 1 is rotatably connected by the ring 17 inside the groove 18. The close contact between the ring 17 and the groove 18 makes the rotation effect better.

[0031] In this embodiment 1, the high-performance CNC radial axial ring rolling machine core roller dual-station mechanism requires adjusting the height of the core roller 1 when processing ring workpieces of different heights. When upward adjustment is needed, two motors 10 are activated. The operation of the two motors 10 causes two gears 9 to rotate towards their opposite ends. The rotation of the two gears 9 drives multiple mating blocks 8 to move towards their opposite ends, which in turn drives two sliders 601 to move towards their opposite ends. The movement of the two sliders 601 causes two lifting rods 603 to move towards their opposite ends, which in turn drives the fixed shaft 2 upward and moves the core roller 1 upward. During the movement of the fixed shaft 2, the L-shaped block 701 moves vertically, and the movement of the L-shaped block 701 causes the hydraulic column 704 to move vertically. During the movement of the hydraulic column 704, the first infrared sensor 12 and multiple second infrared sensors 14 will sense each other. After moving to the height required by the user, the first infrared sensor 12 will drive the hydraulic column 704 to move into the interior of the circular groove 13, thereby fixing the core roller 1 driven by the fixed shaft 2 to the locking block 702. When it is necessary to adjust the height downward, the first sensor will drive the hydraulic column 704 to move out of the interior of the circular groove 13, and then the two motors 10 will rotate in opposite directions, causing the two gears 9 to rotate in opposite directions and the multiple mating blocks 8 to rotate in opposite directions. The movement of the multiple mating blocks 8 will cause the two sliders 601 to move in opposite directions and the two lifting rods 603 to move in opposite directions. The movement of the two lifting rods 603 will cause the fixed shaft 2 to move downward and the core roller 1 to move downward.

[0032] Example 2 The high-performance CNC radial axial rolling mill core roller dual-station adjustment method of this embodiment 2 is characterized by employing the high-performance CNC radial axial rolling mill core roller dual-station mechanism, including the following steps: S1. Start motor 10 to drive gear 9 to rotate; S2, gear 9 drives slider 601 to slide along trapezoidal groove 15 through meshing with mating block 8; S3. The slider 601 drives the lifting rod 603 to move through the first support block 602. The lifting rod 603 drives the fixed shaft 2 to move in the vertical direction through the second support block 604, so that the fixed shaft 2 drives the core roller 1 to rise and fall synchronously. S4. When the core roller 1 moves to the target height, the first infrared sensor 12 inside the hydraulic column 704 moves with the fixed shaft 2 to be opposite to the second infrared sensor 14 inside the corresponding circular groove 13 on the square block 705. The hydraulic column 704 extends into the corresponding circular groove 13 to lock the fixed shaft 2.

[0033] The circular grooves 13 are evenly distributed along the height direction of the square block 705, and each circular groove 13 corresponds to a different working height of the core roller 1.

[0034] In summary, the high-performance CNC radial axial ring rolling machine core roller dual-station mechanism and its adjustment method of the present invention achieve automated dual-station switching and precise height adjustment of the core roller through the rotational cooperation between the core roller and the fixed shaft, the vertical sliding of the core roller along the moving holes on the mounting base plate and cover plate driven by the fixed shaft, and the coordinated cooperation of the lifting devices symmetrically arranged on the left and right sides and the fixing devices arranged on the front and rear sides. The lifting device adopts motor-driven gear and meshing block transmission, combined with the tight contact between the trapezoidal slide groove and the slider and the bidirectional guiding structure of the upper and lower double moving holes, effectively reducing transmission gap and processing vibration, and ensuring the coaxiality and stability of the core roller lifting. The fixing device uses L-shaped blocks, clamping blocks and square blocks to form a bidirectional limit on the fixed shaft, combined with the large driving force of the hydraulic column and the automatic sensing and positioning of the infrared sensor, which can reliably lock the core roller raised to the target height, preventing deviation caused by huge radial extrusion force during processing.

[0035] This invention enables convenient switching between dual workstations, rapid and precise adjustment of the core roller height, low wear on the core roller and support structure, universal processing of ring-shaped workpieces of different heights, and reliable locking after the core roller is raised or lowered. It has the technical effects of high precision, high stability, and high reliability in automatic adjustment of the core roller workstation.

[0036] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.

Start the motor (10) to drive the gear (9) to rotate; S2, the gear (9) drives the slider (601) to slide along the trapezoidal groove (15) through meshing with the mating block (8); S3. The slider (601) drives the lifting rod (603) to move through the first support block (602), and the lifting rod (603) drives the fixed shaft (2) to move in the vertical direction through the second support block (604), so that the fixed shaft (2) drives the core roller (1) to rise and fall synchronously. S4. When the core roller (1) moves to the target height, the first infrared sensor (12) inside the hydraulic column (704) moves with the fixed shaft (2) to be opposite to the second infrared sensor (14) inside the corresponding circular groove (13) on the square block (705). The hydraulic column (704) extends into the corresponding circular groove (13) to lock the fixed shaft (2).

8. A high-performance CNC radial axial ring rolling machine core roller dual-station adjustment method as described in claim 7, characterized in that, The multiple circular grooves (13) are evenly distributed along the height direction of the square block (705), and each circular groove (13) corresponds to a different working height of the core roller (1).
