Description

Technical Field

[0002] A multi-angle servo pipe bending machine is a high-precision pipe bending device that uses a servo control system. It is mainly used for multi-angle and multi-dimensional bending of metal pipes (such as stainless steel, aluminum, and copper pipes). Through advanced servo motor drive and CNC technology, it achieves precise control of complex bending shapes and is suitable for high-requirement processing scenarios in industries such as automotive, aerospace, furniture, and HVAC (heating, ventilation, and air conditioning).

[0003] In the prior art, Chinese utility model patent CN218835712U discloses a multi-angle hydraulic pipe bending machine, including a worktable. A hydraulic cylinder is installed on the top of the worktable, and a first mounting block is fixedly provided at the output end of the hydraulic cylinder. A movable pipe wheel is rotatably connected inside the first mounting block. A mounting side plate is fixedly provided at the bottom edge of the worktable, and a bidirectional threaded rod is rotatably connected inside the mounting side plate. A rotating disk is fixedly provided at one end face of the bidirectional threaded rod, and two symmetrical threaded sleeves are threadedly connected to the outer surface of the bidirectional threaded rod. A connecting plate is fixedly provided at the top of the threaded sleeves. This design allows for convenient movement of the distance between the two fixed pipe wheels, facilitating subsequent multi-angle bending operations of steel pipes. Furthermore, this design makes it easier to handle bending operations of steel pipes of varying lengths, and allows for changing the bending angle of the steel pipe at the same distance. This pipe bending machine is simple in design, easy to operate, and readily applicable.

[0004] Problems with existing technology: The aforementioned multi-angle hydraulic pipe bending machine cannot accurately limit the movement of pipes of various thicknesses during use, resulting in a need to improve the functionality of the pipe bending machine.

[0005] Therefore, there is an urgent need for a multi-angle servo pipe bending machine. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-angle servo pipe bending machine.

[0007] The present invention solves its technical problem through the following technical solution: a multi-angle servo pipe bending machine, including a worktable and a limiting mechanism set above the worktable for limiting the pipe to be bent. The limiting mechanism includes a cylinder A, which is slidably connected to both sides of the worktable. A plurality of sliding grooves are evenly arranged on the top of the cylinder A. A plurality of insertable arc plates are slidably connected to the inner wall of the sliding grooves. A cylinder B is provided at one end of the insertable arc plate. A retaining ring is fixedly installed at one end of both the cylinder A and the cylinder B.

[0008] As a further embodiment of this utility model: a connecting mechanism is provided inside the cylinder A for connecting cylinder A and cylinder B. The connecting mechanism includes a hollow rod, one end of which is slidably connected to a round rod. A tension spring is fixedly installed at the bottom of the hollow rod, and a handle is fixedly installed on the top of the cylinder B.

[0009] As a further embodiment of this utility model: an adjustment mechanism is provided below the workbench for adjusting the support position of the pipe. The adjustment mechanism includes a side plate, which is welded to both sides of the workbench. A lateral displacement hydraulic rod is fixedly installed in the middle of the side plate. A connecting frame is fixedly installed at the extended end of the lateral displacement hydraulic rod. A slider is fixedly installed at one end of the connecting frame. A rotating shaft is rotatably connected to the middle of the slider.

[0010] As a further embodiment of this utility model: one end of the workbench is provided with an extrusion mechanism for extruding and bending the pipe. The extrusion mechanism includes a mounting frame, which is fixed to one end of the workbench by bolts. An extrusion hydraulic rod is fixedly installed at one end of the mounting frame. A push plate is fixedly installed at the extended end of the extrusion hydraulic rod. An extrusion roller is rotatably connected to one end of the push plate.

[0011] As a further improvement of this utility model: multiple support legs are provided below the workbench, and a locking caster wheel is fixedly installed at one end of each support leg.

[0012] As a further improvement of this utility model: a limiting groove is provided at the middle position of the worktable, and the slider is slidably connected to the limiting groove.

[0013] As a further improvement of this utility model: a guide rod is fixedly installed at the middle position of the cylinder A, and a telescopic rod is fixedly installed at one end of the push plate.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. One end of the tension spring is fixedly connected to the round rod, which slides along the inner wall of the hollow rod, thereby causing the cylinder B to descend elastically along the slide groove. The retaining ring is used to clamp and limit the pipe. At the same time, the cylinder B can be raised and lowered by pulling the handle, thereby adjusting the spacing of the retaining ring. This allows the multi-angle hydraulic pipe bending machine to accurately limit the pipes of various thicknesses during use, enriching the functionality of the multi-angle pipe bending machine.

[0016] 2. The connecting frame is moved by the lateral hydraulic rod, and the slider slides along the limit groove to adjust the spacing of the rotating shaft, so that the multi-angle servo pipe bending machine can meet the bending operations of pipes of various lengths;

[0017] 3. By setting up a hydraulic extrusion rod that drives the extrusion rollers through a push plate, the bending point of the pipe is extruded. By controlling the position of the extrusion rollers, the multi-angle servo pipe bending machine can perform multi-angle bending operations on the pipe, thus expanding the application range of the multi-angle servo pipe bending machine.

As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1: As Figure 1-4 As shown, a multi-angle servo pipe bending machine includes a worktable 100 and a limiting mechanism disposed above the worktable 100 for limiting the pipe to be bent. The limiting mechanism includes a cylinder A101, which is slidably connected to both sides of the worktable 100. Multiple grooves 102 are evenly cut on the top of the cylinder A101. Multiple insertable arc-shaped plates 103 are slidably connected to the inner wall of the grooves 102. The multiple insertable arc-shaped plates 103 move along the grooves 102. A cylinder B104 is welded to one end of each insertable arc-shaped plate 103. The cylinder B104 moves relative to the cylinder A101. A retaining ring 105 is bolted to one end of both cylinder A101 and cylinder B104, thereby adjusting the distance between the retaining rings 105 at both ends. The cylinder A101 is internally equipped with a connecting mechanism for connecting cylinder A101 to cylinder B104. Multiple support legs 200 are welded to the bottom of the workbench 100. One end of each support leg 200 is fixed with a locking caster wheel 300 via bolts. The multi-angle servo pipe bending machine is moved via the multiple locking caster wheels 300. The connecting mechanism includes a hollow rod 201, one end of which is slidably connected to a round rod 202. The round rod 202 slides along the inner wall of the hollow rod 201. A tension spring 203 is fixed to the bottom of the hollow rod 201 via bolts, one end of which is fixedly connected to the round rod 202. A handle 204 is fixed to the top of cylinder B104 via bolts, allowing cylinder B104 to be raised and lowered via the handle 204.

[0033] In this embodiment, one end of the tension spring 203 is fixedly connected to the round rod 202. The round rod 202 slides along the inner wall of the hollow rod 201, thereby causing the cylinder B104 to elastically descend along the slide groove 102. The retaining ring 105 clamps and limits the pipe. At the same time, the cylinder B104 can be pulled up and down by the handle 204, thereby adjusting the spacing of the retaining ring 105. This allows the multi-angle hydraulic pipe bending machine to accurately limit the pipes of various thicknesses during use, enriching the functionality of the multi-angle pipe bending machine.

[0034] Example 2: As Figure 1-5 As shown, a multi-angle servo pipe bending machine has an adjustment mechanism below the worktable 100 for adjusting the support position of the pipe. The adjustment mechanism includes side plates 301 welded to both sides of the worktable 100. A lateral displacement hydraulic rod 302 is bolted to the middle of the side plate 301. A connecting frame 303 is bolted to the extended end of the lateral displacement hydraulic rod 302. The lateral displacement hydraulic rod 302 drives the connecting frame 303 to move. A slider 304 is bolted to one end of the connecting frame 303. The slider 304 slides along a limiting groove 400. A rotating shaft 305 is rotatably connected to the middle of the slider 304. The spacing of the rotating shaft 305 is adjusted. A limiting groove 400 is cut in the middle of the worktable 100. The slider 304 is slidably connected to the limiting groove 400. The limiting groove 400 supports the slider 304. The movement trajectory of 04 is limited. One end of the workbench 100 is provided with an extrusion mechanism for extruding and bending the pipe. The extrusion mechanism includes a mounting frame 401, which is fixed to one end of the workbench 100 by bolts. One end of the mounting frame 401 is fixed with an extrusion hydraulic rod 402 by bolts. The extended end of the extrusion hydraulic rod 402 is fixed with a push plate 403 by bolts. One end of the push plate 403 is rotatably connected to an extrusion roller 404. The extrusion hydraulic rod 402 drives the extrusion roller 404 to move through the push plate 403. A guide rod 310 is fixed to the middle position of the cylinder A101 by bolts. The guide rod 310 guides the lifting trajectory of the cylinder B104. One end of the push plate 403 is fixed with a telescopic rod 410 by bolts. The telescopic rod 410 limits the movement trajectory of the extrusion roller 404.

[0035] In this embodiment, the connecting frame 303 is moved by the lateral hydraulic rod 302, and the slider 304 slides along the limiting groove 400 to adjust the spacing of the rotating shaft 305. This allows the multi-angle servo pipe bending machine to meet the bending operations of pipes of various lengths. By setting the extrusion hydraulic rod 402, the extrusion roller 404 is moved through the push plate 403 to extrude the bending part of the pipe. By controlling the position of the extrusion roller 404, the multi-angle servo pipe bending machine can perform multi-angle bending operations on the pipe, thus expanding the application range of the multi-angle servo pipe bending machine.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
