Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, specifically a pipe bending machine for producing shower columns. Background Technology

[0002] Shower columns are a common bathroom fixture, typically consisting of an upper curved pipe and a lower straight pipe, used to provide a showering function. During the manufacturing process of shower columns, a pipe bending machine is used to bend the pipes to meet the bending requirements of the shower column production process, thus shaping the pipes to conform to the production requirements of the shower column.

[0003] For example, patent CN221817079U discloses an aluminum tube bending machine, including an operating table. When the operator needs to bend aluminum tubes of different sizes, the aluminum tube can be placed inside the cylinder. Then, the operator can move four round rods on the surface of the cylinder inward, so that the surface of the arc-shaped abutment plate at the bottom of the round rod can clamp the aluminum tube. At the same time, the surface of the round rod has multiple insertion holes. When the operator determines the position of the round rod, the operator can move the pull plate to drive the insertion rod through the insertion hole inside the fixing block and insert it into the insertion hole on the surface of the round rod to fix and limit the round rod. When bending the aluminum tube, although the above case can clamp and limit the aluminum tube well by using the arc-shaped abutment plate to clamp the aluminum tube, it also restricts the vertical displacement of the aluminum tube. As a result, when removing the aluminum tube, the arc-shaped abutment plate needs to be loosened and the aluminum tube pulled out, which is not convenient for quickly removing the tube.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing pipe bending machine used in shower column production. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe bending machine for shower column production, so as to solve the problem mentioned in the above-mentioned case in the background art that uses an arc-shaped abutment plate to clamp the aluminum pipe. Although it can clamp and limit the aluminum pipe well, it also restricts the vertical displacement of the aluminum pipe. As a result, when removing the aluminum pipe, the arc-shaped abutment plate needs to be loosened and the aluminum pipe pulled out, which is not convenient for quickly removing the pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe bending machine for producing shower columns, comprising a workbench, a drive motor mounted on the bottom of the workbench via a bracket, a support platform mounted on one side of the workbench, a rotating column rotatably connected to the support platform, and a fixed bending block fixedly connected to the top of the rotating column; a transmission shaft mounted on the output end of the drive motor, the transmission shaft rotatably connected to the support platform, a U-shaped block mounted on the outer wall of the transmission shaft, and a rotating bending block mounted on one side inside the U-shaped block; and a removal mechanism for quickly removing the shower column is provided on the workbench.

[0007] Furthermore, the extraction mechanism includes an electric push rod, which is fixedly connected to the worktable via a fixing block. A connecting plate is installed at the output end of the electric push rod, and a rack is installed on one side of the connecting plate. A first gear is fixedly connected to the rotating column, and the rack meshes with the first gear.

[0008] Furthermore, the workbench is provided with an auxiliary mechanism for assisting in the removal of the shower column. The auxiliary mechanism includes a transmission rod, which is rotatably connected to the inside of the workbench. A second gear is installed on the top of the transmission rod, and the second gear meshes with a rack.

[0009] Furthermore, a first bevel gear is installed on the outer wall of the transmission rod, and a second bevel gear meshes with one side of the first bevel gear. A bidirectional lead screw is fixedly connected inside the second bevel gear. The bidirectional lead screw is rotatably connected to the inside of the worktable. Clamping blocks are threaded to both ends of the outer wall of the bidirectional lead screw, and the clamping blocks are slidably connected to the inside of the worktable.

[0010] Furthermore, a movable block is slidably connected inside one side of the U-shaped block, and a locking pin is movably connected between the movable block and the U-shaped block. Both the movable block and the U-shaped block have slots corresponding to the positions of the locking pins.

[0011] Furthermore, an angle plate is installed on one side of the support platform, and a threaded hole is provided on the angle plate, with a threaded rod connected to the inside of the threaded hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This shower column production pipe bending machine starts the electric push rod when the shower column pipe needs to be removed. The meshing of the rack and the first gear drives the rotating column to rotate, so that the fixed bending block rotates to the appropriate position to facilitate the removal of the pipe. At the same time, the movement of the rack will also drive the second gear, the transmission rod, the first bevel gear and the second bevel gear to rotate, which in turn causes the bidirectional lead screw to rotate, realizing the opposite or opposite movement of the clamping blocks, releasing the clamping blocks to assist in the removal of the pipe.

[0014] Furthermore, by adjusting the position of the locking pin in the slot, the position of the moving block within the U-shaped block can be changed, thereby altering the bending position of the shower column pipe to meet more processing requirements. The angle plate and threaded rod installed on the support platform can limit the rotation angle of the U-shaped block by placing the threaded rod in different threaded holes, effectively improving the accuracy of pipe bending.

[0015] Furthermore, the shower column pipe is placed between the fixed bend and the rotating bend, and the drive motor is started. The drive shaft drives the U-shaped block and the rotating bend to rotate, thus bending the pipe. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 and Figure 6The present invention provides the following technical solution: a pipe bending machine for producing shower columns, comprising a workbench 1, a drive motor 2 mounted on the bottom of the workbench 1 via a bracket, a support platform 3 mounted on one side of the workbench 1, a rotating column 8 rotatably connected to the support platform 3, and a fixed bending block 5 fixedly connected to the top of the rotating column 8; a transmission shaft 7 mounted on the output end of the drive motor 2, the transmission shaft 7 rotatably connected to the support platform 3, a U-shaped block 4 mounted on the outer wall of the transmission shaft 7, and a rotating bending block 6 mounted on one side inside the U-shaped block 4; a removal mechanism for quickly removing the shower column is provided on the workbench 1; the removal mechanism includes an electric push rod 10, the electric push rod 10 fixedly connected to the workbench 1 via a fixing block, a connecting plate mounted on the output end of the electric push rod 10, a rack 11 mounted on one side of the connecting plate, and a first gear 12 fixedly connected to the rotating column 8, the rack 11 and the first gear 12 meshing with each other.

[0025] When using, such as Figure 1 and Figure 2 As shown, first, place the shower column on the side of the fixed bend block 5, making it abut against the rotating bend block 6, and place one end of the shower column on the top of the sliding block, so that one end of the shower column abuts against the sliding block. Then, start the drive motor 2 mounted on the bottom of the workbench 1 via the bracket. After the drive motor 2 starts, its output end drives the transmission shaft 7 to rotate, so that the transmission shaft 7 is rotatably connected to the inside of the support platform 3, as shown. Figure 4 and Figure 5 As shown, a U-shaped block 4 is installed on the outer wall of the drive shaft 7, and a rotating bend 6 is installed on one side inside the U-shaped block 4. A rotating column 8 is rotatably connected to the support platform 3, and a fixed bend 5 is fixedly connected to the top of the rotating column 8. Therefore, when the drive shaft 7 rotates, it drives the U-shaped block 4 to rotate, and the U-shaped block 4 rotates synchronously with the bend 6, bending the shower column pipe placed between the fixed bend 5 and the rotating bend 6. When it is necessary to remove the shower column, as... Figure 2 and Figure 3 As shown, since the electric push rod 10 is fixedly connected to the workbench 1 via a fixed block, when the electric push rod 10 is started, the extension and retraction of its output end will drive the connecting plate to move. The rack 11 installed on one side of the connecting plate will move accordingly. Since the first gear 12 is fixedly connected to the rotating column 8, the rack 11 and the first gear 12 mesh with each other. Therefore, the movement of the rack 11, through meshing with the first gear 12, drives the first gear 12 to rotate, thereby causing the rotating column 8 to rotate. When the rotating column 8 rotates, the fixed bend 5 fixed at its top will also rotate, so that the non-arc side of the fixed bend 5 faces the shower column. At this time, the shower column is not limited by the fixed bend 5 and the rotating bend 6, and it can be easily removed.

[0026] Example 2: Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 Based on Embodiment 1, an auxiliary mechanism is also disclosed, the specific structure of which is as follows:

[0027] The auxiliary mechanism includes a transmission rod 15, which is rotatably connected to the inside of the workbench 1. A second gear 13 is mounted on the top of the transmission rod 15, and the second gear 13 meshes with the rack 11. A first bevel gear 14 is mounted on the outer wall of the transmission rod 15. A second bevel gear 16 meshes with one side of the first bevel gear 14. A double-acting screw 17 is fixedly connected inside the second bevel gear 16. The double-acting screw 17 is rotatably connected to the inside of the workbench 1. Clamping blocks 18 are threaded to both ends of the outer wall of the double-acting screw 17 and are slidably connected to the inside of the workbench 1. A moving block 9 is slidably connected to one side of the U-shaped block 4. A locking pin 22 is movably connected between the moving block 9 and the U-shaped block 4. Both the moving block 9 and the U-shaped block 4 have slots corresponding to the positions of the locking pin 22. An angle plate 19 is mounted on one side of the support platform 3. A threaded hole 21 is provided on the angle plate 19, and a threaded rod 20 is threadedly connected inside the threaded hole 21.

[0028] After rack 11 moves, as Figure 2 and Figure 3 As shown, since the rack 11 and the second gear 13 mesh with each other, the movement of the rack 11 will drive the second gear 13 to rotate. Since the second gear 13 is fixedly connected to the transmission rod 15, the second gear 13 will drive the transmission rod 15 to rotate. Figure 3 As shown, a first bevel gear 14 is installed on the outer wall of the transmission rod 15. A second bevel gear 16 meshes with one side of the first bevel gear 14. A double-acting screw 17 is fixedly connected inside the second bevel gear 16. The double-acting screw 17 is rotatably connected to the inside of the worktable 1. Therefore, when the transmission rod 15 rotates, it drives the first bevel gear 14 to rotate. The first bevel gear 14, through meshing with the second bevel gear 16, drives the second bevel gear 16 to rotate. The second bevel gear 16 drives the double-acting screw 17 to rotate. Since clamping blocks 18 are threaded to both ends of the outer wall of the double-acting screw 17 and are slidably connected to the inside of the worktable 1, when the double-acting screw 17 rotates, because the threads at both ends are in opposite directions, the two clamping blocks 18 will make linear movements toward or away from each other inside the worktable 1, thereby clamping or releasing the shower column pipe. When removing the shower column pipe, the clamping blocks 18 can be released to assist in removing the shower column pipe. Figure 4 and Figure 5As shown, a movable block 9 is slidably connected inside one side of the U-shaped block 4, and a locking pin 22 is movably connected between the movable block 9 and the U-shaped block 4. Both the movable block 9 and the U-shaped block 4 have slots corresponding to the positions of the locking pin 22. By adjusting the position of the locking pin 22 in the slots, the position of the movable block 9 within the U-shaped block 4 can be changed, thereby altering the bending position of the shower column pipe and meeting more processing requirements, such as... Figure 4 and Figure 5 As shown, since an angle plate 19 is installed on one side of the support platform 3, and a threaded hole 21 is provided on the angle plate 19, and a threaded rod 20 is threadedly connected inside the threaded hole 21, by placing the threaded rod 20 inside different threaded holes 21, the U-shaped block 4 can abut against the threaded rod 20 when rotating, which can limit the rotation angle of the U-shaped block 4 and improve the accuracy of pipe bending.
