Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe bending mechanisms, and in particular to a stainless steel pipe bending mechanism. Background Technology

[0002] Stainless steel pipe bending mechanism is a mechanical device specially designed for processing stainless steel and similar metal materials. Its main function is to bend stainless steel pipes and their fittings.

[0003] Chinese patent document CN221414584U discloses a stainless steel pipe bending mechanism, including a bending device, light-duty wheels, heavy-duty wheels, and a main wheel. The light-duty wheels are positioned above the bending device, and a pulley is fitted below them. A first transmission belt is fitted onto the surface of the pulley, and the main wheel is fitted onto the surface of the first transmission belt. A convex ring is fixedly connected to the surface of the main wheel, and a pulley is fitted below it. This stainless steel pipe bending mechanism utilizes a main wheel to drive a set of light-duty wheels, and a small motor drives another set of light-duty wheels via pulleys. All light-duty wheels are simultaneously fitted with pulleys. Using a force transmission method, when the stainless steel pipe enters the first set, it is transmitted to the main wheel by the light-duty wheels at both ends. Because the main wheel and the other light-duty wheels are not on the same horizontal plane, when the stainless steel pipe is transmitted, the convex ring on the main wheel, in conjunction with the heavy-duty wheel and a light-duty wheel, bends the stainless steel pipe into a helical spring shape.

[0004] The existing technology has the following problems:

[0005] Although the above-mentioned utility model can bend stainless steel pipes into a spiral spring shape, the position of the pulley is fixed and cannot be moved, so it can only bend steel pipes of a single diameter, resulting in poor applicability. In addition, the belt connecting multiple transmission pulleys leads to low transmission efficiency. Utility Model Content

[0012] Preferably, the upper part of the slide rod is movably connected to a disassembly mechanism, the disassembly mechanism including a connecting rod, the connecting rod being fixedly connected to the middle part of the upper part of the inner cavity of the slide rod, a limiting rod being fixedly connected to the middle part of the connecting rod, a locking block being slidably connected to both the left and right ends of the limiting rod, a connecting block being fixedly connected to the opposite side of the two locking blocks, a slider being fixedly connected to the upper part of the opposite side of the two connecting blocks, and a compression spring being fixedly connected to the middle part of the opposite side of the two locking blocks.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 - Figure 7 As shown, a stainless steel pipe bending mechanism includes a workbench 1, a conveying mechanism 2 movably connected to the middle of the inner cavity of the workbench 1, a slide rail 4 fixedly connected to the bottom of the left side of the inner cavity of the workbench 1, a clamping mechanism 3 movably connected to the upper surface of the slide rail 4, a slide rod 8 slidably connected to the upper part of the right side of the workbench 1, a base plate 9 fixedly connected to the lower part of the outer periphery of the slide rod 8, and a sleeve roller 5 slidably sleeved on the outer periphery of the slide rod 8.

[0029] The conveying mechanism 2 includes a motor 21, the output end of which is fixedly connected to a drive wheel 22. The middle part of the upper surface of the drive wheel 22 is rotatably connected to the middle part of the upper part of the worktable 1. Belts 26 are slidably connected to the upper and lower sides of the outer periphery of the drive wheel 22. Driven wheel 24 is rotatably connected to the left side of the middle part of the upper part of the worktable 1. Driven wheel 25 is rotatably connected to the right side of the middle part of the upper part of the worktable 1. The left part of the drive wheel 25 located inside the upper belt 26 is slidably connected to the left side of the outer periphery of the driven wheel 24. The right part of the drive wheel 25 located inside the lower belt 26 is slidably connected to the right side of the outer periphery of the driven wheel 25. Conveying rollers 23 are fixedly connected to the middle part of the upper part of the drive wheel 22, driven wheel 24, and driven wheel 25.

[0030] It should be noted that the workbench 1 is used to place and process steel pipes, the slide bar 8 is used to bend the steel pipes in conjunction with the base plate 9 and the sleeve roller 5, and the base plate 9 is used to support the sleeve roller 5. The conveying mechanism 2 is mainly used to convey stainless steel pipes horizontally on the workbench 1. After the motor 21 starts, its output end drives the drive wheel 22 to rotate. The drive wheel 22 drives the driven wheel 24 and driven wheel 25 to rotate synchronously through the belt 26. The drive wheel 22 connects the driven wheel 24 and driven wheel 25 through the belt 26, realizing the transmission of power. The drive wheel 22, driven wheel 24 and driven wheel 25 are all fixedly connected to the middle of the upper part of the drive wheel 22, driven wheel 24 and driven wheel 25. When the belt 26 moves, the conveying roller 23 rotates accordingly, thereby effectively and smoothly conveying the stainless steel pipes on the workbench 1.

[0031] like Figure 2 As shown, the clamping mechanism 3 includes a support plate 33. The lower surface of the support plate 33 is slidably connected to the right side of the upper surface of the slide rail 4. A second motor 31 is fixedly connected to the rear side of the upper surface of the slide rail 4. A threaded rod 32 is fixedly connected to the output end of the second motor 31. The outer circumference of the threaded rod 32 is threadedly connected to the middle part of the support plate 33. Clamping rollers 34 are rotatably connected to both the left and right sides of the upper middle part of the support plate 33.

[0032] It should be noted that the clamping mechanism 3 is mainly used to clamp and fix the stainless steel pipe in conjunction with the conveyor roller 23 for subsequent bending operations. After the motor 2 31 is started, its output end drives the threaded rod 32 to rotate. Since the outer circumference of the threaded rod 32 is threadedly connected to the middle of the support plate 33, the support plate 33 will move closer to or further away from the conveyor roller 23 along the slide rail 4. The clamping roller 34 on the upper part of the support plate 33 moves accordingly. When the clamping roller 34 contacts the stainless steel pipe, the stainless steel pipe can be clamped and fixed by adjusting the position of the support plate 33.

[0033] like Figure 3 and Figure 5 As shown, a rotating mechanism 6 is movably connected to the right side of the workbench 1. The rotating mechanism 6 includes a motor 61. The output end of the motor 61 is fixedly connected to a drive gear 62. A driven gear ring 63 is rotatably connected to the upper surface of the right side of the inner cavity of the workbench 1. The inner cavity of the driven gear ring 63 meshes with the drive gear 62. Multiple tooth grooves 64 are opened on the lower part of the outer periphery of the slide rod 8. The outer periphery of the driven gear ring 63 meshes with the tooth grooves 64.

[0034] It should be noted that the rotating mechanism 6 is mainly used to drive the slide bar 8 and its base plate 9 and roller 5 to rotate, thereby realizing the bending operation of the stainless steel tube. After the motor 3 61 starts, its output end drives the driving gear 62 to rotate. The driving gear 62 meshes with the driven gear ring 63, so the driven gear ring 63 will rotate accordingly. Since the outer circumference of the driven gear ring 63 meshes with the tooth groove 64 on the lower part of the outer circumference of the slide bar 8, the slide bar 8 will rotate following the rotation of the driven gear ring 63. In this way, when the stainless steel tube is fixed by the clamping mechanism 3, the bending operation of the stainless steel tube can be realized by driving the rotating mechanism 6.

[0035] like Figure 6 and Figure 7 As shown, a disassembly mechanism 7 is movably connected to the upper part of the slide rod 8. The disassembly mechanism 7 includes a connecting rod 74, which is fixedly connected to the middle of the upper part of the inner cavity of the slide rod 8. A limit rod 75 is fixedly connected to the middle of the connecting rod 74. A locking block 71 is slidably connected to both the left and right ends of the limit rod 75. A connecting block 72 is fixedly connected to the opposite side of the two locking blocks 71. A slider 73 is fixedly connected to the upper part of the opposite side of the two connecting blocks 72. A compression spring 76 is fixedly connected to the middle of the opposite side of the two locking blocks 71.

[0036] It should be noted that the disassembly mechanism 7 is mainly used to facilitate the disassembly and replacement of the sleeve roller 5 on the slide bar 8. When it is necessary to disassemble the sleeve roller 5, the two sliders 73 can be pushed to move them towards each other, causing the connecting block 72 to drive the locking block 71 to compress the compression spring 76. At this time, the locking block 71 will disengage from the slot on the slide bar 8, thus allowing the sleeve roller 5 to be disassembled from the slide bar 8. The design of the connecting rod 74 and the limiting rod 75 makes the disassembly mechanism 7 more stable and reliable, and less prone to damage. The upper part of the slider 73 has a groove to facilitate the movement of the locking block 71, making the movement of the locking block 71 smoother and less prone to jamming.

[0037] like Figure 3 and Figure 4 As shown, a limiting groove 65 is provided on the right side of the upper part of the worktable 1, and the lower part of the outer periphery of the slide rod 8 is slidably connected to the inside of the limiting groove 65.

[0038] It should be noted that the limiting groove 65 is used to limit the movement trajectory of the slide bar 8, making the slide bar 8 more stable during rotation and less prone to deviation.

[0039] like Figure 2 and Figure 4 As shown, two grooves 35 are provided on the rear side of the upper left side of the worktable 1, and the outer periphery of the lower part of the clamping roller 34 is slidably connected to the inside of the groove 35.

[0040] It should be noted that the groove 35 is used to limit the movement range of the clamping roller 34, making the clamping roller 34 more stable during movement and less prone to deviation.

[0041] like Figure 3 and Figure 5 As shown, the upper part of the driven gear 25 passes through the middle part of the driven gear ring 63.

[0042] It should be noted that the upper part of the driven wheel 25 passes through the middle part of the driven gear ring 63, so that the rotating mechanism 6 and the conveying mechanism 2 do not interfere with each other, and the driven gear ring 63 can simultaneously mesh with the tooth groove 64 on the driving gear 62 and the slide bar 8, thereby realizing the transmission of power and the rotation of the slide bar 8.

[0043] The working principle of this utility model is as follows: First, the steel pipe is placed between the conveying roller 23 and the clamping roller 34. Motor 2 31 is started, driving the threaded rod 32 to rotate, causing the support plate 33 to move the clamping roller 34 towards the conveying roller 23. This allows the clamping roller 34 to cooperate with the conveying roller 23 to clamp the steel pipe. Then, motor 1 21 is started, driving the drive wheel 22 to rotate, causing the two belts 26 to drive the driven wheels 24 and 25 to rotate simultaneously. This causes the conveying roller 23 to move the steel pipe to the right. After the steel pipe reaches the appropriate position, motor 3 61 is started, driving the drive gear 62 to rotate. The drive gear 62 drives the driven gear ring 63 to rotate, which in turn drives the slide bar 8 to rotate. The rotation of the slide bar 8 causes the sleeve roller 5 to bend the steel pipe. When the diameter of the steel pipe is not suitable for the sleeve roller 5, the two sliders 73 are pushed, causing the locking block 71 to move towards each other, disengaging it from the sleeve roller 5. Then, the sleeve roller 5 is removed and replaced with a suitable one.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
