[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0042] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Please refer to Figures 1-6 An embodiment of this utility model provides a device for cutting off excess material from a bent tube, comprising:

[0044] Workbench 1;

[0045] The clamping mechanism 2 is set on the workbench 1 and is used to clamp the bent pipe 7 and make both ends of the bent pipe 7 extend out of the clamping mechanism 2.

[0046] The first driving mechanism 3 is set on the workbench 1 and is connected to the clamping mechanism 2 for driving the bent pipe 7 clamped by the clamping mechanism 2 to rotate.

[0047] The support mechanism 4 is located on one side of the clamping mechanism 2 and is used to support the large end 72 of the bend 7 when the excess material of the small end 71 of the bend 7 is removed, and to release the support of the large end 72 when the excess material of the large end 72 of the bend 7 is removed.

[0048] The cutting mechanism 5 is located on one side of the clamping mechanism 2 and is used to cut off the excess material from the bent pipe 7.

[0049] The second drive mechanism 6 is mounted on the worktable 1 and is connected to the cutting mechanism 5 for transmission. It is used to drive the cutting mechanism 5 to move along the x-axis and y-axis directions respectively. The x-axis direction is the direction in which the cutting mechanism 5 moves closer to or further away from the clamping mechanism 2, and the y-axis direction is perpendicular to the x-axis direction.

[0050] In this embodiment, when removing excess material from both ends of the bend 7, the bend 7 is first clamped and fixed by the clamping mechanism 2, and then the clamping mechanism 2 is driven by the first driving mechanism 3 to rotate the bend 7 so that the large end 72 of the bend 7 faces the cutting mechanism 5; then the cutting mechanism 5 is driven by the second driving mechanism 6 to move and align with the large end 72 of the bend 7, and then moves towards the bend 7 to remove excess material from its large end 72; at this time, the outer diameter of the bend 7 gradually decreases in the direction away from the cutting mechanism 5, and the bend 7 is fixed and stable in the clamping mechanism 2.

[0051] After the excess material at the large end 72 is removed, the first drive mechanism 3 drives the clamping mechanism 2 to rotate the bent tube 7, so that the small end 71 of the bent tube 7 faces the cutting mechanism 5. At this time, the support mechanism 4 supports the large end 72 of the bent tube 7 to prevent the bent tube 7 from sliding in the clamping mechanism 2 due to the outer diameter of the bent tube 7 gradually increasing in the direction away from the cutting mechanism 5, thus ensuring the stability of the bent tube 7 when the excess material at the small end 71 is removed. At the same time, the second drive mechanism 6 drives the cutting mechanism 5 to move and align with the small end 71 of the bent tube 7. Then the cutting mechanism 5 moves toward the bent tube 7 to remove the excess material at its small end 71.

[0052] The scrap removal device of this application realizes the automatic removal of scrap material at both ends of the bend 7, which is convenient to operate, has high processing efficiency, and ensures the processing quality of the bend.

[0053] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the first drive mechanism 3 includes a base plate 31 disposed above the worktable 1, and an indexing head motor 33 disposed inside the worktable 1, which drives the base plate 31 to rotate via an indexing head 32.

[0054] In this embodiment, the indexing head motor 33 drives the base plate 31 to rotate through the indexing head 32, and the base plate 31 drives the bent tube 7 held by the clamping mechanism 2 to rotate. The rotation angle is precise, ensuring that the excess material at the small end 71 and the large end 72 of the bent tube 7 is accurately removed.

[0055] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the clamping mechanism 2 includes a lower module 21 and an upper module 22, and a mold cavity 23 matching the contour of the bent pipe 7 is provided between the lower module 21 and the upper module 22.

[0056] A first bracket 24 is fixedly installed on the top surface of the workbench 1 on one side of the seat plate 31; a clamping cylinder 25 is fixedly installed on the first bracket 24 above the seat plate 31, a transmission plate 26 is fixedly connected to the bottom end of the clamping cylinder 25, a transmission shaft is fixedly installed on the bottom surface of the transmission plate 26, and the transmission shaft is rotatably connected to the top plate 27 through a bearing; a first guide sleeve 28 is fixedly installed on both sides of the clamping cylinder 25 on the first bracket 24, and a first guide rod 29 is slidably sleeved inside the first guide sleeve 28, and the bottom end of the first guide rod 29 is fixedly connected to the transmission plate 26;

[0057] The lower module 21 is fixedly mounted on the top surface of the base plate 31. Vertical second guide rods 210 are fixedly mounted on both sides of the top surface of the base plate 31 on the lower module 21. The upper module 22 is fixedly mounted on the bottom surface of the top plate 27 directly above the lower module 21. Second guide sleeves 211 are fixedly mounted on both sides of the upper module 22 on the top plate 27. The second guide sleeves 211 are slidably sleeved with the second guide rods 210 in a corresponding manner.

[0058] In this embodiment, when clamping the bent pipe 7, the top plate 27 is first moved upward by the clamping cylinder 25, and the top plate 27 causes the upper mold 22 to separate from the lower mold 21; then the bent pipe 7 is placed into the mold cavity 23 of the lower mold 21; then the top plate 27 is moved downward by the clamping cylinder 25, and the top plate 27 causes the upper mold 22 to close with the lower mold 21, thereby fixing and clamping the bent pipe 7; the mold cavity 23 has a high degree of fit with the bent pipe 7 and a large contact area, which avoids the problem of deformation of the bent pipe 7 caused by clamping, and the clamping effect is good.

[0059] In a preferred embodiment, such as Figure 3 and Figure 4 As shown, the support mechanism 4 includes a vertical plate 41 and a support plate 42;

[0060] The vertical plate 41 is fixedly installed on one side of the lower module 21, and the side of the vertical plate 41 closest to the lower module 21 is the mounting surface; two parallel slide rails 43 are fixedly installed on the mounting surface, and slide blocks 44 are slidably connected to the outer sides of the two slide rails 43; guide plates 45 are symmetrically arranged on both sides of the slide blocks 44 on the mounting surface; guide grooves 46 are provided on the guide plates 45; the guide grooves 46 include a straight section parallel to the slide rails 43 and an arc section that turns away from the lower module 21.

[0061] Support plate 42 is supported on the large end 72 of the bend 7; support plate 72 is perpendicular to slide rail 43, and a rotating seat 47 embedded between two guide plates 45 is fixedly connected to one side of it; rotating seat 47 is located on the side of slide 44 near the arc segment, one end of rotating seat 47 is rotatably connected to slide 44 through a first shaft, and the two ends of the first shaft are respectively sleeved with first guide wheels 48 embedded in the guide groove 46 on the same side; the other two sides of rotating seat 47 are respectively provided with second guide wheels 49 embedded in the guide groove 46 on the same side; a drive cylinder 410 is provided on the side of slide 44 away from rotating seat 47 to drive it to slide along slide rail 46.

[0062] In this embodiment, when the small end 71 is trimmed of excess material, the support plate 42 supports the large end 72 of the bent tube 7 to prevent the bent tube 7 from sliding in the mold cavity 23.

[0063] When removing excess material from the large end 72, the drive cylinder 410 drives the slide block 44 to slide along the slide rail 43, separating the support plate 42 from the large end 72 of the bend 7. When the second guide wheel 49 enters the arc section of the guide groove 46, the rotating seat 47 rotates outward, driving the support plate 42 to rotate outward. At this time, the support plate 42 avoids the large end 72 of the bend 7, preventing interference when removing excess material from the large end 72. The support effect is good, ensuring the stability of the bend 7 when removing excess material from the small end 71.

[0064] In a preferred embodiment, such as Figure 2 and Figure 5 As shown, the second drive mechanism 6 includes two parallel first guide rails 61 fixedly mounted on the top surface of the worktable 1, the first guide rails 61 being parallel to the y-axis direction; a lower slide plate 62 is slidably connected to the top of the two first guide rails 61, a first lead screw 63 is parallelly mounted between the two first guide rails 61, a first transmission block 64 is threaded onto the first lead screw 63, the first transmission block 64 is fixedly connected to the lower slide plate 62, and a first motor that drives the first lead screw 63 to rotate is fixedly mounted inside the worktable 1;

[0065] Two parallel second guide rails 65 are fixedly installed on the top surface of the lower slide plate 62, and the second guide rails 65 are parallel to the x-axis direction; the top of the two second guide rails 65 is slidably connected to the upper slide plate 66, and a second lead screw 67 is arranged parallel between the two second guide rails 65. The second lead screw 67 is threadedly sleeved with a second transmission block 68, and the second transmission block 68 is fixedly connected to the upper slide plate 66. A second motor 69 that drives the second lead screw 67 to rotate is fixedly installed at one end of the lower slide plate 62.

[0066] In this embodiment, the cutting mechanism 5 is disposed on the top surface of the upper slide plate 66. The first motor drives the first lead screw 63 to rotate, which can move the cutting mechanism 5 in the y-axis direction; the second motor 69 drives the second lead screw 67 to rotate, which can move the cutting mechanism 5 in the x-axis direction. This adjusts the position of the cutting mechanism 5 so that it is aligned when cutting off the excess material at the small end 71 or the large end 72, and moves the cutting mechanism 5 toward the bend 7 to complete the removal of excess material, thus realizing the automatic removal of excess material from the bend 7.

[0067] In a preferred embodiment, such as Figure 2 and Figure 6 As shown, the cutting mechanism 5 includes a spindle 51, a cutter head 52, and a drive motor 53;

[0068] The main shaft 51 is parallel to the x-axis direction, and two frame plates 54 are rotatably connected to it via bearings. The two frame plates 54 are fixedly installed on the top surface of the upper slide plate 66, and two slide rods 55 parallel to the main shaft 51 are fixedly installed on the frame plates 54.

[0069] The cutter head 52 is fixedly mounted on one end of the spindle 51. A protective cover 56 is provided on the outer periphery of the cutter head 52. The protective cover 56 is slidably connected to two slide rods 55. A buffer spring 57 is sleeved on the slide rods 55 between the protective cover 56 and the support plate 54.

[0070] A second bracket 58 is fixedly installed on the top surface of the upper slide plate 66, and a drive motor 53 is fixedly installed on the top of the second bracket 58. The drive motor 53 drives the main shaft 51 to rotate through a pulley and a belt.

[0071] In this embodiment, the drive motor 53 drives the spindle 51 to rotate, thereby driving the cutter head 52 to rotate at high speed. When the cutter head 52 approaches the bend 7, it cuts off the remaining material, which is effective for cutting off the remaining material at the small end 71 or the large end 72 of the circle. The protective cover 56 blocks the cut-off remaining material, avoiding the problem of the remaining material splashing and causing injury to people, thus ensuring high safety.
