Description

[0002] The left-right bending type CNC pipe bending machine is an automated device that achieves complex spatial pipe bending by working in concert with two bending arms on the left and right. It is precisely controlled by a CNC system and can efficiently complete pipe bending operations at multiple angles and on multiple planes.

[0003] The existing CNC pipe bending machine with left and right bending does not have a cutting system, requires multiple feedings, and has low working efficiency; the existing CNC pipe bending machine with left and right bending requires multiple manual feedings, and the workpiece positioning is inaccurate, which will result in inconsistent product quality.

[0004] Existing CNC pipe bending machines with left and right bending can only complete one bending step per feeding. If multiple workpieces are to be obtained, repeated feeding is required, which complicates the operation, makes it difficult to effectively guarantee production efficiency, and slows down the overall production cycle. Each repeated feeding requires repositioning of the pipe, and manual positioning inevitably introduces errors, making it difficult to achieve consistent product quality, making it difficult to effectively control the scrap rate, and thus making it difficult to facilitate user operation.

[0030] Example 1

[0031] like Figure 1 - Figure 7 As shown, this utility model provides a technical solution: a CNC pipe bending machine with left and right bending, including a fixed platform 1 with a slide rail, a feeding device 2 slidably connected to the top of the fixed platform 1 with a slide rail, a cutting device 5 fixedly connected to the top of the fixed platform 1 with a slide rail, a bending device 3 slidably connected to one side of the fixed platform 1 with a slide rail, and a bending device 4 provided on the bending device 3 with a bending device 4.

[0033] The cutting device 5 also includes a fixing block 59, a fixing block 3 56 fixedly connected to the top of the fixing block 59, a fixing block 4 57 provided on one side of the fixing block 3 56, a cylinder clamp 58 fixedly connected to the side of the fixing block 4 57 away from the fixing block 3 56, a retainer 2 5011 fixedly connected to the bottom of the cylinder clamp 58, and a support frame 5010 fixedly connected to the bottom of the retainer 2 5011.

[0034] In this embodiment, the electric slide rail 4 51 is activated, causing the slider 52, which is slidably connected to the electric slide rail 4 51, to slide. This causes the lifting platform 53, which is fixedly connected to the slider 52, to slide on the electric slide rail 4 51. This further causes the fixture 55, which is fixedly connected to the lifting platform 53, to slide. Finally, the cutter 54, which is fixedly connected to the fixture 55, moves vertically, thereby achieving the purpose of cutting the pipe. The cutter 54 is a high-speed rotating pipe cutter in the prior art.

[0035] The cylinder clamp 58 is activated, causing the fixed block 4 57, which is fixedly connected to the output end of the cylinder clamp 58, to move until the fixed block 4 57 contacts the fixed block 3 56, thereby achieving the purpose of fixing the pipe and ensuring that the pipe will not slip during the cutting process.

[0036] Among them, the second fixture 5011 serves to fix the cylinder clamp 58, the first fixture 55 serves to fix the cutting tool 54, and the support frame 5010 serves to provide support.

[0037] Example 2

[0038] like Figure 1 - Figure 6 As shown, the bending device 3 includes an electric slide rail 31, one side of which is fixedly connected to a slider 14. A slider 35 is slidably connected to the top of the electric slide rail 31. A cylinder 32 is fixedly connected to the top of the slider 35. A connecting block 33 is fixedly connected to the output end of the cylinder 32. A fixing block 34 is fixedly connected to the side of the connecting block 33 near the output end away from the cylinder 32. A cylinder slide rail 36 is fixedly connected to the top of the electric slide rail 31. A slider 4 37 is slidably connected to the cylinder slide rail 36. A bending device 2 4 is fixedly connected to the side of the slider 4 37 away from the cylinder slide rail 36.

[0039] The bending device 2 4 includes a cylinder rotating device 41, an auxiliary clamp 42 is provided at the top of the cylinder rotating device 41, a support column 44 is rotatably connected to one side of the cylinder rotating device 41, a fixing block 2 43 is fixedly connected to the top of the support column 44, and the support column 44 and the slider 4 37 are fixedly connected to the side away from the cylinder slide rail 36.

[0040] The sliding rail fixed platform 1 includes a support platform 11, with an electric sliding rail 12 fixedly connected to the top of the support platform 11 and an electric sliding rail 2 13 fixedly connected to one side of the support platform 11. A slider 14 is slidably connected to the electric sliding rail 2 13. The feeding device 2 includes a pipe clamp 21, with a slider 22 fixedly connected to the bottom of the pipe clamp 21. The slider 22 is slidably connected to the electric sliding rail 1 12.

[0041] In this embodiment, the activation of the electric slide rail 2 13 causes the slider 14, which is slidably connected to the electric slide rail 2 13, to slide vertically, thereby causing the bending device 3, which is fixedly connected to the slider 14, to slide vertically. Furthermore, the bending device 2 4, which is mounted on the bending device 3, slides vertically. The activation of the cylinder slide rail 36 causes the slider 4 37, which is slidably connected to the cylinder slide rail 36, to slide horizontally, thereby causing the support column 44, which is fixedly connected to the slider 4 37, to slide horizontally. Furthermore, the cylinder rotating device 41, which is rotatably connected to the support column 44, moves horizontally, and simultaneously causes the fixing block 2 43, which is fixedly connected to the support column 44, to move horizontally. Finally, the auxiliary clamp 42, which is mounted on the cylinder rotating device 41, moves horizontally, thus achieving the purpose of allowing the fixing block 2 43 to bend in different directions when moved to the left or right side of the pipe.

[0042] The auxiliary clamp 42 is activated to work with the fixed block 43 to bend the pipe. The auxiliary clamp 42 is a cylinder-driven clamp in the prior art. The auxiliary clamp 42 is activated by the cylinder rotation device 41 to rotate the cylinder rotation device 41, thereby achieving the purpose of the auxiliary clamp 42 working with the fixed block 43 to bend the pipe. The cylinder rotation device 41 is implemented by a servo motor drive system in the prior art.

[0043] The activation of the electric slide rail 31 causes the slider 35, which is slidably connected to the electric slide rail 31, to slide horizontally. This, in turn, causes the cylinder 32, which is fixedly connected to the slider 35, to slide horizontally. This, in turn, causes the connecting block 33, which is fixedly connected to the cylinder 32, to slide horizontally. Finally, the fixing block 34, which is fixedly connected to the connecting block 33, slides horizontally. The activation of the cylinder 32 then causes the connecting block 33, which is fixedly connected to the cylinder 32, to move in a direction perpendicular to the horizontal, thereby achieving the purpose of bending the pipe in conjunction with the fixing block 43.

[0044] The electric slide rail 12 is activated, causing the slider 22, which is slidably connected to the electric slide rail 12, to move. This, in turn, causes the pipe clamp 21, which is fixedly connected to the slider 22, to move, thereby achieving the purpose of feeding. The pipe clamp 21 adopts a clamping and rotating system in the prior art, which can achieve bending in different directions on the same side by rotating the pipe.

[0045] Working principle:

[0046] like Figure 1 - Figure 7 As shown, the electric slide rail 4 51 is activated, causing the slider 5 52, which is slidably connected to the electric slide rail 4 51, to slide. This causes the lifting platform 53, which is fixedly connected to the slider 5 52, to slide on the electric slide rail 4 51. This further causes the fixture 1 55, which is fixedly connected to the lifting platform 53, to slide. Finally, the cutter 54, which is fixedly connected to the fixture 1 55, moves vertically, thereby achieving the purpose of cutting the pipe. The cutter 54 is a high-speed rotating pipe cutter in the prior art.

[0047] The cylinder clamp 58 is activated, causing the fixed block 4 57, which is fixedly connected to the output end of the cylinder clamp 58, to move until the fixed block 4 57 contacts the fixed block 3 56, thereby achieving the purpose of fixing the pipe and ensuring that the pipe will not slip during the cutting process.

[0048] When the pipe contacts the fixed block 43, the auxiliary clamp 42 is activated. After the auxiliary clamp 42 and the fixed block 43 clamp the pipe together, the cylinder rotation device 41 is activated. The pipe is then bent by rotating the cylinder rotation device 41. After one side is bent, the electric slide rail 13 is activated, causing the slider 14, which is slidably connected to the electric slide rail 13, to slide vertically. This causes the bending device 3, which is fixedly connected to the slider 14, to slide vertically, and further causes the bending device 4, which is mounted on the bending device 3, to slide vertically. The cylinder slide rail 36 is activated, causing the slider 47, which is slidably connected to the cylinder slide rail 36, to slide horizontally. This causes the support column 44, which is fixedly connected to the slider 47, to slide horizontally. This further causes the cylinder rotating device 41, which is rotatably connected to the support column 44, to move horizontally. At the same time, the fixing block 2 43, which is fixedly connected to the support column 44, moves horizontally. Finally, the auxiliary clamp 42 on the cylinder rotating device 41 moves horizontally, causing the fixing block 2 43 to change direction, ultimately achieving the effect of bending on both the left and right sides.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
