[0002] The main function of a flanging machine is to fold or roll the edges of metal materials using rollers and pressure plates to enhance the structural strength and sealing of the product.
[0003] When flanging cylindrical workpieces, the workpiece is first fixed on a fixture, and the motor drives the fixture and workpiece to rotate synchronously so that the flanging roller flanging the edge of the workpiece. The flanging roller rubs against the workpiece for a long time, and the surface temperature rises, which causes the workpiece to become out of round at the flanging position, the roller surface to wear, and the hardness to decrease. Workers need to replace the roller every once in a while. In order to maintain the flanging quality, one end of the roller is fixed inside the bearing. The disassembly process is time-consuming and laborious, which reduces production efficiency.
[0004] Therefore, it is necessary to provide a new pressure roller device for flanging machines to solve the above problems. Utility Model Content
[0005] The technical problem solved by this utility model is to provide a pressure roller device for a flanging machine that reduces roller wear and improves production efficiency.
[0006] To solve the above-mentioned technical problems, the present invention provides a pressure roller device for a flanging machine, comprising: a worktable, on which slide rails are symmetrically mounted, and a mounting box is slidably connected to the surface of the slide rails; a groove is provided in the center of the side wall of the mounting box, and a support rod and a fixing sleeve are slidably connected inside the groove; the fixing sleeve and the slider are threadedly connected to a screw respectively; a first bearing seat is installed at one end of the fixing sleeve, and an upper pressure roller is rotatably connected inside the first bearing seat; a support rod is rotatably connected inside the slider, and a plurality of through holes are provided on the side wall of the support rod; a limiting rod is fixedly connected to the side wall of the fixing sleeve, and the limiting rod is slidably connected to the through holes; a fixing plate is fixedly connected to one end of the support rod, and a plurality of second bearing seats are circumferentially mounted on the side wall of the fixing plate, and a lower pressure roller is rotatably connected inside the second bearing seats.
[0007] Preferably, drive motors are mounted on the surfaces of both the workbench and the mounting box, and the output shaft of the drive motor is connected to a screw.
[0008] Preferably, the bottom end of the mounting box is fixedly connected to a first fixing block, and the first fixing block is threadedly connected to the screw located at the bottom end of the workbench.
[0009] Preferably, two screws are symmetrically installed inside the mounting box, and these screws are aligned with the sliding groove.
[0010] Preferably, the side wall of the mounting box is symmetrically provided with slots, and a plurality of second fixing blocks are installed at the edge of the side wall of the fixing plate. The interior of the second fixing block is slidably connected to a locking block with one end in a hemispherical shape, and the locking block is slidably connected to the slot. The interior of the second fixing block is equipped with a first spring, and one end of the first spring is connected to the second fixing block.
[0011] Preferably, the second fixing block and the second bearing seat are in one-to-one correspondence, one of the second fixing blocks is slidably connected to the slide groove, and the slide groove has a funnel-shaped cross-section.
[0012] Preferably, a gear is fixedly connected to the side wall of the support rod, and an arc-shaped limiting strip is fixedly connected to the top of the slider, with the elastic limiting strip abutting against the gear; a rack box is installed inside the mounting box, and a rack is slidably connected inside the rack box, with the rack meshing with the gear; multiple second springs are installed inside the rack box, and the second springs are connected to the side wall of the rack.
[0013] Compared with related technologies, the pressure roller device for flanging machines provided by this utility model has the following advantages: This utility model provides a pressure roller device for a flanging machine. After the workpiece is flanged, the drive motor corresponding to the fixed plate operates, driving the slider, the support rod, and the fixed plate to move downwards. As the support rod continues to move downwards, it first disengages from the limiting rod, then the gear contacts the rack, and the rack pushes the gear to rotate clockwise, causing the fixed plate to rotate on the side wall of the mounting box, thus disengaging the newly used lower pressure roller from the slide groove. When processing another workpiece, as the slider pushes the fixed plate upwards, the fixed plate does not rotate due to the presence of the limiting rod. This allows the fixed plate to rotate 120° during its downward movement while one lower pressure roller processes a workpiece, enabling the replacement of another lower pressure roller to process the next workpiece. The lower pressure rollers are used alternately, avoiding excessive temperature caused by prolonged use of a single lower pressure roller, reducing wear, and extending the service life of the lower pressure roller. When one of the lower pressure rollers becomes too worn to be used, it is moved to the fixed plate, so that the qualified lower pressure roller is aligned with the slide groove. During the downward movement of the lower pressure roller, the downward movement distance of the fixed plate is controlled to prevent the support rod from disengaging from the limit rod, so that the lower pressure roller can continue to be used to process the workpiece. After the workpiece is processed, the damaged lower pressure roller on the surface of the fixed plate is replaced, thereby improving production efficiency. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Please refer to... Figures 1 to 6 , Figure 1 A schematic diagram of a preferred embodiment of the pressure roller device for a flanging machine provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the mounting box. Figure 3 for Figure 1 The top view of the internal structure of the mounting box shown; Figure 4 for Figure 2 The top view of the internal structure of the fixed block shown; Figure 5 for Figure 2 The diagram shows an enlarged view of the structure at point A. Figure 6 for Figure 5The diagram shows a side view of the gear structure. A pressure roller device for a flanging machine includes a worktable 1, with slide rails 2 symmetrically mounted on the surface of the worktable 1. A mounting box 4 is slidably connected to the surface of the slide rails 2. A groove 5 is provided in the center of the side wall of the mounting box 4. A support rod 91 and a fixing sleeve 11 are slidably connected inside the groove 5. The fixing sleeve 11 and a slider 10 are threadedly connected to a screw 31. A first bearing seat 71 is mounted on one end of the fixing sleeve 11, and an upper pressure roller 7 is rotatably connected inside the first bearing seat 71. To facilitate the sliding of the support rod 91 and the fixing sleeve 11 inside the groove 5, the upper pressure roller 7 and the lower pressure roller 8 move up and down, facilitating the processing of workpieces by the upper pressure roller 7 and the lower pressure roller 8.
[0017] The slider 10 is internally connected to a support rod 91, and the side wall of the support rod 91 is provided with multiple through holes 92. The side wall of the fixed sleeve 11 is fixedly connected to a limiting rod 12, and the limiting rod 12 is slidably connected to the through holes 92. One end of the support rod 91 is fixedly connected to a fixed disk 9, and the side wall of the fixed disk 9 is annularly mounted with multiple second bearing seats 81, and the lower pressure roller 8 is rotatably connected inside the second bearing seats 81. When the surface of one of the lower pressure rollers 8 is worn too much, the lower pressure roller 8 used can be replaced by rotating the fixed disk 9. The fixed disk 9 drives the support rod 91 to rotate inside the slider 10, and the lower pressure roller 8 on the side wall of the fixed disk 9 rotates to replace the lower pressure roller 8 used. After the workpiece is processed, the damaged lower pressure roller 8 on the surface of the fixed disk 9 is replaced to improve production efficiency.
[0018] Both the workbench 1 and the mounting box 4 are equipped with drive motors 3, and the output shaft of the drive motor 3 is connected to a screw 31. The bottom end of the mounting box 4 is fixedly connected to a first fixing block 41, which is threadedly connected to the screw 31 located at the bottom end of the workbench 1. In order to facilitate the rotation of the drive motor 3, the drive motor 3 drives the screw 31 to rotate, and using the principle of helical transmission, pushes the mounting box 4 to slide on the surface of the guide rail 2.
[0019] Two screws 31 are symmetrically installed inside the mounting box 4. The screws 31 are aligned with the slide groove 5. By controlling the direction of the drive motor 3, the direction of the screws 31 in the mounting box 4 is adjusted, thereby driving the upper pressure roller 7 and the lower pressure roller 8 to move along the slide groove 5 respectively.
[0020] The mounting box 4 has symmetrical slots 6 on its side wall. Multiple second fixing blocks 13 are installed at the edge of the side wall of the fixing plate 9. The interior of the second fixing block 13 is slidably connected to a hemispherical locking block 15. The locking block 15 is slidably connected to the slot 6. A first spring 14 is installed inside the second fixing block 13. One end of the first spring 14 is connected to the second fixing block 13. When one of the lower pressure rollers 8 is aligned with the upper pressure roller 7, the two second fixing blocks 13 are aligned with the slot 6. The first spring 14 extends and pushes the locking block 15 into the interior of the slot 6. During the up-and-down movement of the fixing plate 9, the locking block 15 moves up and down along the slot 6, thereby increasing the stability of the up-and-down movement of the fixing plate 9.
[0021] The second fixing block 13 corresponds one-to-one with the second bearing seat 81. One of the second fixing blocks 13 is slidably connected to the slide groove 5. The slide groove 5 has a funnel-shaped cross-section. In order to facilitate the rotation of the fixing plate 9 and the clamping block 15 to squeeze the side wall of the slide groove 5, since the slide groove 5 has a funnel-shaped cross-section and the side wall of the slide groove 5 is inclined, it is easy to squeeze the clamping block 15, which has a spherical end, into the interior of the second fixing block 13, so that the second fixing block 13 is separated from the slide groove 5, which facilitates the rotation of the fixing plate 9.
[0022] A gear 18 is fixedly connected to the side wall of the support rod 91, and a limiting strip 17 with an arc-shaped side wall is fixedly connected to the top of the slider 10. The elastic limiting strip 17 abuts against the gear 18. A rack box 16 is installed inside the mounting box 4, and a rack 19 is slidably connected inside the rack box 16, with the rack 19 meshing with the gear 18. Multiple second springs 20 are installed inside the rack box 16, and the second springs 20 are connected to the side wall of the rack 19. When the slider 10 drives the fixed plate 9 and the support rod 91 to move downward, the support rod 91 disengages from the limiting rod 12. As the support rod 91 continues to move downward, the gear 18 contacts the rack 19, and the rack 19 pushes the gear 18 to rotate clockwise. Since the direction of rotation of the gear 18 is opposite to the curvature of the limiting strip 17, and the side wall of the limiting strip 17 is arc-shaped, it is convenient for the gear 18 to slide from the side wall of the limiting strip 17. The rotation of the gear 18 drives the gear 19 to rotate clockwise. When the fixed disk 9 rotates, the thrust of the gear 18 on the rack 19 is less than the resistance experienced by the rack 19, causing the rack 19 to drive the gear 18 to rotate clockwise. When the gear 18 and the fixed disk 9 rotate to 120°, the rack 19 disengages from the gear 18, and the other lower pressure roller 8 aligns with the slide groove 5. When the slider 10 pushes the gear 18 upward, the gear 18 contacts the rack 19. At this time, the rack 19 wants to push the gear 18 to rotate counterclockwise. Since the direction of the gear 18 is opposite to the curvature of the limiting strip 17, the rotational resistance of the gear 18 increases, and the thrust of the gear 18 on the rack 19 is greater than the resistance experienced by the rack 19, causing the rack 19 to move into the rack box 16 and compress the second spring 20. The rack 19 separates from the gear 18, allowing the gear 18, the support rod 91, and the fixed disk 9 to move upward in a straight line without rotating.
[0023] The working principle of the pressure roller device for the flanging machine provided by this utility model is as follows: When flanging the workpiece, the drive motor 3 is turned on and the direction of the drive motor 3 is controlled, thereby adjusting the direction of the screw 31 in the mounting box 4, which respectively drives the upper pressure roller 7 and the lower pressure roller 8 to move along the slide groove 5, which facilitates the processing of the workpiece. At this time, the support rod 91 slides on the side wall of the limiting rod 12, and the limiting block 15 slides inside the slot 6, which increases the stability of the up and down movement of the fixed plate 9 and prevents the fixed plate 9 from rotating. After the workpiece processing is completed, the drive motor 3 corresponding to the upper pressure roller 7 operates, driving the fixed sleeve 11, the limiting rod 12, and the upper pressure roller 7 to move to the top; the drive motor 3 corresponding to the fixed disk 9 operates, driving the slider 10, the support rod 91, and the fixed disk 9 to move downwards; as the support rod 91 continues to move downwards, the support rod 91 first disengages from the limiting rod 12, and then the gear 18 contacts the rack 19. The rack 19 pushes the gear 18 to rotate clockwise. Since the direction of rotation of the gear 18 is opposite to the curvature of the limiting rod 17 at this time, and the side wall of the limiting rod 17 is arc-shaped, it is convenient for the gear 18 to slide from the side wall of the limiting rod 17. The rotation of the gear 18 drives the fixed disk 9 to rotate. The disc 9 drives the limiting block 15 to rotate and press against the side wall of the mounting box 4. Since one end of the limiting block 15 is hemispherical, it is convenient for the limiting block 15 to enter the interior of the second fixing block 13 to compress the first spring 14, which facilitates the rotation of the fixing disc 9 on the side wall of the mounting box 4, so that the newly used lower pressure roller 8 is misaligned with the slide groove 5. At this time, the thrust of the gear 18 on the rack 19 is less than the resistance received by the rack 19, so that the rack 19 drives the gear 18 to rotate clockwise. When the gear 18 and the fixing disc 9 rotate to 120°, the rack 19 disengages from the gear 18, the other lower pressure roller 8 aligns with the slide groove 5, the through hole 92 aligns with the limiting rod 12, and the limiting block 15 enters the interior of the slide groove 5 and the slot 6.When processing another workpiece, as the slider 10 pushes the gear 18 upward, the gear 18 contacts the rack 19. At this time, the rack 19 attempts to push the gear 18 to rotate counterclockwise. Since the rotation direction of the gear 18 is opposite to the curvature of the limiting strip 17, the rotational resistance of the gear 18 increases. The pushing force of the gear 18 on the rack 19 is greater than the resistance experienced by the rack 19, causing the rack 19 to move into the rack housing 16 and compress the second spring 20. The rack 19 then separates from the gear 18, facilitating the processing of the gear... The wheel 18, the support rod 91, and the fixed disk 9 move upward in a straight line without rotating. As the support rod 91 moves upward, the limiting rod 12 passes through the through hole 92, increasing the stability of the fixed disk 9's movement. When one of the lower pressure rollers 8 processes a workpiece, the fixed disk 9 rotates 120° during its downward movement to replace it with another lower pressure roller 8 to process the next workpiece. The lower pressure rollers 8 are used alternately to avoid overheating caused by prolonged use of a single lower pressure roller 8, thus slowing down wear and extending their service life. When one of the lower pressure rollers 8 becomes too worn to be used, it is rotated to the fixed disk 9, aligning a qualified lower pressure roller 8 with the slide groove 5. During the downward movement of the lower pressure roller 8, the downward movement distance of the fixed disk 9 is controlled to prevent the support rod 91 from disengaging from the limiting rod 12, allowing this lower pressure roller 8 to continue processing workpieces. After the workpiece processing is completed, the damaged lower pressure roller 8 on the surface of the fixed disk 9 is replaced, improving production efficiency.
