Description

Technical Field

[0001] This utility model relates to sheet metal processing equipment, and more particularly to a three-roll forming device for flared thin-walled open tubes. Background Technology

[0002] Thin-walled open tubes are important components in mechanical design. The conventional manufacturing process using sheet metal typically involves blanking, rounding, welding, flaring, and cutting. This conventional process involves numerous steps and requires various equipment and molds, resulting in high manufacturing costs. For thin-walled flared open tubes, the traditional manufacturing process requires specialized equipment, including laser cutting machines, rounding machines, welding machines, and flaring forming machines, involving blanking, rounding, welding, flaring, and cutting. Without flaring forming equipment, processing is very difficult.

[0003] Furthermore, existing conventional three-roll plate bending machines have some drawbacks. For example, Chinese patent CN213495799U discloses a three-roll plate bending machine, which includes a base, a first support plate and a second support plate fixed on the base, two drive rollers, and a drive assembly for driving the drive rollers. Although the detachable connection between the fixed assembly and the central shaft, the cooperation between the baffle and the rebound spring, and the setting of the push plate and push rod all facilitate the unloading of the three-roll plate bending machine, the following shortcomings still exist in the use of the machine: 1. The baffle needs to be repeatedly fixed with locking bolts before and after processing, which is cumbersome, results in long downtime, and low production efficiency; 2. The drive rollers are not easy to disassemble, making later maintenance and replacement inconvenient. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a three-roll forming device for flared thin-walled open tubes, which saves equipment costs, labor costs, shortens the manufacturing cycle, and improves product quality.

[0005] The purpose of this utility model is achieved as follows:

[0006] A three-roll forming apparatus for flared thin-walled tubes includes a worktable, a side plate A fixedly connected to the top wall of the worktable, and a side plate B also fixedly connected to the top wall of the worktable, wherein the side plate B and the side plate A are symmetrically distributed about the worktable. The apparatus further includes:

[0007] An automatic disengagement assembly includes a mounting plate fixedly connected to the top wall of the workbench. Symmetrically distributed guide rails are fixedly connected to the top wall of the mounting plate. A square guide block is slidably connected to the inner wall of the guide rail. A flipping plate is fixedly connected to the outer wall of the square guide block. A linkage plate is fixedly connected to the outer wall of the flipping plate. A rotating seat B is fixedly connected to the outer wall of the linkage plate. A rotating seat A is fixedly connected to the top wall of the mounting plate. A cylinder is rotatably connected to the outer wall of the rotating seat A, and the output end of the cylinder is rotatably connected to the rotating seat B.

[0008] The slide plate is slidably connected to the flip plate and the outer wall of side plate A. The slide plate, side plate A and the outer walls of side plate B are all fixedly connected with evenly distributed bearing seats.

[0009] The component is designed for easy disassembly and is located on the inner wall of the bearing housing.

[0010] Adjustment components are located on the top wall of the skateboard.

[0011] Furthermore, the easy-to-disassemble component includes a linkage rod fixedly connected to the inner wall of the bearing seat, a drive plate fixedly connected to the outer wall of the linkage rod, and uniformly distributed drive rods fixedly connected to the outer wall of the drive plate. The drive rods are slidably connected to a rotating roller through a drive groove.

[0012] Furthermore, the adjustment assembly includes an adjustment screw rotatably connected to the top wall of the slide plate, a positioning plate threadedly connected to the outer wall of the adjustment screw, and an adjustment handle fixedly connected to the top wall of the adjustment screw.

[0013] Furthermore, a connecting rod is fixedly connected to the outer wall of the linkage rod on the left side, a driven gear is fixedly connected to the outer wall of the connecting rod, and a driving gear is also fixedly connected to the outer wall of the connecting rod, and the driving gear meshes with the driven gear.

[0014] Furthermore, a support frame is fixedly connected to the outer wall of the workbench, a base is fixedly connected to the outer wall of the support frame, a drive motor is fixedly connected to the top wall of the base, a drive pulley is fixedly connected to the output end of the drive motor, a driven pulley is driven by the drive pulley through the belt body, and the driven pulley is fixedly connected to the drive gear.

[0015] Furthermore, both the flip plate and the top wall of side plate A are fixedly connected to the positioning plate.

[0016] Furthermore, a groove is provided on the outer wall of the top roller, and a boss is provided on the outer wall of the bottom roller.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention redesigns the upper and lower rollers, setting a boss on the upper roller and a corresponding groove on the lower roller. This eliminates the need to purchase specialized flaring and forming equipment, and also eliminates the need for welding, flaring, and cutting processes, thus saving the parts manufacturing cycle, improving parts quality, and reducing parts manufacturing costs.

[0019] This invention provides a stable and smooth sliding track for the square guide block by setting a guide rail. The square guide block drives the flipping plate to move and flip at the same time, thereby driving the drive plate to drive the drive rod to disengage from the drive groove. Its movement trajectory is to move to the right first and then flip. No manual operation is required, which simplifies the operation process and reduces the time wasted due to frequent operation of locking bolts. This makes the whole processing process more continuous, significantly reduces downtime, and improves production efficiency. It solves the problem of the existing technology where the baffle needs to be fixed by locking bolts repeatedly before and after processing, which is cumbersome, has long downtime, and low production efficiency.

[0020] This invention connects the bearing seat and the roller by having a drive rod slide into the drive groove of the roller. This eliminates the need for complex tools or tedious alignment operations, greatly improving the assembly efficiency of the equipment and reducing the time and labor costs required for installation. It also facilitates later maintenance and replacement. Furthermore, the unified design avoids the cost of modifying the equipment design. The rollers are interchangeable, solving the problem in the prior art where the drive roller is inconvenient to disassemble, thus hindering later maintenance and replacement.

Example 1

[0032] See Figure 1-8 , Figure 1 A schematic diagram of a three-roll forming device for flaring thin-walled open tubes is shown. As shown, the three-roll forming device for flaring thin-walled open tubes according to this invention includes a worktable 1, a side plate A8 fixedly connected to the top wall of the worktable 1, and a side plate B9 also fixedly connected to the top wall of the worktable 1. The side plate B9 and the side plate A8 are symmetrically distributed about the worktable 1. The device also includes:

[0033] The automatic disengagement assembly includes a mounting plate 23 fixedly connected to the top wall of the worktable 1. Symmetrically distributed guide rails 22 are fixedly connected to the top wall of the mounting plate 23. Square guide blocks 24 are slidably connected to the inner walls of the guide rails 22. A flipping plate 10 is fixedly connected to the outer wall of the square guide blocks 24. A linkage plate 21 is fixedly connected to the outer wall of the flipping plate 10. A rotating seat B26 is fixedly connected to the outer wall of the linkage plate 21. A rotating seat A25 is fixedly connected to the top wall of the mounting plate 23. A cylinder 27 is rotatably connected to the outer wall of the rotating seat A25, and the output end of the cylinder 27 is rotatably connected to the rotating seat B26. The mounting plate 23 is fixed to the top wall of the worktable 1. The symmetrically distributed guide rails 22 on it provide sliding guidance for the square guide block 24. The square guide block 24 is fixedly connected to the flip plate 10. When the cylinder 27 is activated, since one end of the cylinder 27 is rotatably connected to the rotating seat A25 and the other end is rotatably connected to the rotating seat B26, and the rotating seat B26 is fixed on the linkage plate 21 (the linkage plate 21 is connected to the flip plate 10), the extension and retraction movement of the cylinder 27 will drive the flip plate 10 to slide along the guide rail 22 to achieve the corresponding action. This can assist subsequent components such as the rotating roller 20 to perform corresponding disengagement operations, and facilitate the handling of the processed thin-walled open tube.

[0034] The slide plate 12 is slidably connected to the outer wall of the flip plate 10 and the side plate A8. The slide plate 12, the side plate A8 and the outer wall of the side plate B9 are all fixedly connected with evenly distributed bearing seats 16.

[0035] The component is designed for easy disassembly and is located on the inner wall of the bearing housing 16.

[0036] The adjustment component is located on the top wall of the slide plate 12.

[0037] The easy-to-disassemble component includes a linkage rod 15 fixedly connected to the inner wall of the bearing seat 16, a drive plate 17 fixedly connected to the outer wall of the linkage rod 15, and evenly distributed drive rods 18 fixedly connected to the outer wall of the drive plate 17. The drive rods 18 are slidably connected to a rotating roller 20 through a drive groove 19. When the rotating roller 20 needs to be disassembled, it is only necessary to push the rotating roller 20 to drive the drive groove 19 to slide along the drive rod 18 and then move the drive rod 18 to complete the disassembly, which facilitates the replacement, maintenance and other operations of the rotating roller 20.

[0038] The adjustment assembly includes an adjustment screw 13 rotatably connected to the top wall of the slide plate 12. A positioning plate 11 is threadedly connected to the outer wall of the adjustment screw 13, and an adjustment handle 14 is fixedly connected to the top wall of the adjustment screw 13. When the adjustment handle 14 is rotated, the adjustment screw 13 will rotate accordingly. Due to the threaded connection between the adjustment screw 13 and the positioning plate 11, the positioning plate 11 will move up and down along the adjustment screw 13. Since the flip plate 10 and the top wall of the side plate A8 are both fixedly connected to the positioning plate 11, the position of the positioning plate 11 can be adjusted to change the height and other positional states of the slide plate 12 and other related components, thereby adjusting the position of the rollers 20 and other components connected to the slide plate 12 to adapt to the flaring processing requirements of thin-walled open tubes of different specifications.

[0039] A connecting rod 30 is fixedly connected to the outer wall of the left-side linkage rod 15. A driven gear 28 is fixedly connected to the outer wall of the connecting rod 30. A driving gear 29 is also fixedly connected to the outer wall of the connecting rod 30. The driving gear 29 meshes with the driven gear 28. The driven gear 28 is rotated through the core of the driving gear 29, which in turn meshes with the connecting rod 30 to rotate, thereby driving the linkage rod 15 to rotate.

[0040] A support frame 2 is fixedly connected to the outer wall of the workbench 1. A base 3 is fixedly connected to the outer wall of the support frame 2. A drive motor 4 is fixedly connected to the top wall of the base 3. A drive pulley 5 is fixedly connected to the output end of the drive motor 4. A driven pulley 6 is driven by the drive pulley 5 through the belt body 7. The driven pulley 6 is fixedly connected to the drive gear 29. The output end of the drive motor 4 drives the drive pulley 5 to rotate, which in turn drives the driven pulley 6 to rotate through the belt body 7, which in turn drives the drive gear 29 to rotate.

[0041] The top walls of the flip plate 10 and the side plate A8 are both fixedly connected to the positioning plate 11, and the flip plate 10 and the side plate A8 provide fixed support for the positioning plate 11.

[0042] In this embodiment, a groove 32 is provided on the outer wall of the top roller 20, and a boss 31 is provided on the outer wall of the bottom roller 20. As the roller 20 continues to rotate, the boss 31 continuously applies radial pressure to the thin-walled open tube from the inside of the tube and the groove 32 from the outside of the tube. During the cyclic rotation of the roller 20, the tube wall material of the thin-walled open tube gradually deforms and extends along the shape of the boss 31 and the groove 32, and the opening of the tube is slowly expanded. This is a key step in achieving flaring. In this way, the shape of the tube gradually changes to the flared shape, realizing the operation of flaring thin-walled tube.

[0043] Working principle:

[0044] This utility model provides a three-roll forming device for flared thin-walled open tubes. In use, the mounting plate 23 is fixed to the top wall of the workbench 1. The symmetrically distributed guide rails 22 on the plate provide sliding guidance for the square guide block 24. The square guide block 24 is fixedly connected to the flip plate 10. When the cylinder 27 is activated, since one end of the cylinder 27 is rotatably connected to the rotating seat A25 and the other end is rotatably connected to the rotating seat B26, and the rotating seat B26 is fixed on the linkage plate 21 (the linkage plate 21 is connected to the flip plate 10), the extension and retraction of the cylinder 27 will drive the flip plate 10 to slide along the guide rail 22 to achieve the corresponding action. This can assist subsequent components such as the rotating roller 20 in performing corresponding disassembly operations, and facilitate the handling of the processed thin-walled open tubes. When the rotating roller 20 needs to be disassembled, it is only necessary to push the rotating roller 20 to drive the drive groove 19 to slide along the drive rod 18 and then move it out of the drive rod 18 to complete the disassembly, which facilitates the replacement and maintenance of the rotating roller 20.

[0045] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
