Abstract
Description
Technical Field
[0001] The utility model relates to the field of metal forming, in particular to a five-axis pipe bending tool. Background Art
[0002] Steel pipes are widely used as load-bearing components in five-axis machining equipment. Due to their large size and thick walls, traditional manufacturing processes typically involve welding three sections of steel pipe together. This method suffers from low strength and the risk of breakage during use. Therefore, existing processes have gradually shifted to single-stage bending of steel pipes to improve strength and stability.
[0003] In existing technology, some five-axis pipe bending fixtures cannot be quickly changed while processing steel pipes. This significantly reduces production efficiency, prolongs equipment downtime, and reduces output per unit time. Furthermore, this increases labor costs, requiring workers to expend more time and energy loading and unloading steel pipes. Furthermore, it affects product quality stability, making it difficult to ensure consistent bending parameters after each change. This also limits production flexibility. Therefore, a five-axis pipe bending fixture has been proposed to address these issues. Utility Model Content

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] Reference Figures 1 to 3 The utility model provides an embodiment of a five-axis equipment pipe bending tool, comprising a folding plate 1 and a lower base plate 6. The folding plate 1 is an important component of the entire bending tool. It is usually made of high-strength metal material and has sufficient hardness and stability. By playing the bending function, the head and the bending part of the workpiece are subjected to force at the same time through the left and right levers, which plays the role of bending and preventing deformation. The bottom of the folding plate 1 contacts the top of the lower base plate 6, and the lower base plate 6 can provide support force for the folding plate 1. The top of the folding plate 1 is fixedly connected with a slider 2, and the slider 2 can be driven to move by moving the folding plate 1. The right side of the rear end of the folding plate 1 is fixedly connected with a steel pipe cover 3. The steel pipe cover 3 seals one end of the workpiece to prevent liquid from flowing out. A movable groove 9 is opened on the top of the lower base plate 6. The outer side of the slider 2 is slidably connected to the inside of the movable groove 9. The slider 2 moves in the inside of the movable groove 9, so that the workpiece is positioned, and the bending angle of the workpiece can be controlled.
[0032] The top rear end of the lower base plate 6 is provided with a mounting groove 11, which can fix the subsequent workpiece inside. The inside of the mounting groove 11 is fixedly connected to the steel pipe guide mechanism 5, which guides the deformation of the steel pipe through the contoured groove in the steel pipe guide mechanism 5. The top of the steel pipe guide mechanism 5 is fixedly connected to the upper baffle 4, which can prevent the workpiece from moving up and down. The upper baffle 4 and the steel pipe guide mechanism 5 are both provided with multiple bolt holes 10. Bolts installed inside the bolt holes 10 can fasten the upper baffle 4 and the steel pipe guide mechanism 5 to each other. The splicing design makes the replacement and placement of workpieces more convenient. Operators can quickly adapt to steel pipes of different specifications, thereby improving the flexibility and efficiency of the production line. It reduces equipment downtime, thereby improving overall production efficiency.
[0033] The right side of the lower base plate 6 is fixedly connected with a locking mechanism 7, and the locking mechanism 7 can lock the workpiece to prevent deformation. The right side of the locking mechanism 7 is fixedly connected with a steel pipe cover plate 2 8, and the steel pipe cover plate 2 8 can seal the other end of the steel pipe to prevent liquid outflow. A plurality of limiting grooves 13 are provided on the left side of the top of the folding plate 1. The limiting groove 13 can add subsequent workpieces therein. An extrusion groove 12 is provided on the right side of the folding plate 1. The interior of the extrusion groove 12 is coupled with a steel pipe 19, and the extrusion groove 12 can place the steel pipe 19 therein. The outside of the steel pipe 19 contacts the front end of the steel pipe guide mechanism 5, and the steel pipe 19 is deformed by guiding the steel pipe 19 through the profiling groove in the steel pipe guide mechanism 5. The left end of the steel pipe 19 is slidably connected to the inside of the locking mechanism 7, and the locking mechanism 7 can prevent the steel pipe 19 from internal deformation during processing.
[0034] Reference Figure 3 and Figure 4 Rosin water is poured into the interior of the steel pipe 19, and a ball 14 is movably connected to the interior of the limiting groove 13. The ball 14 can roll inside the limiting groove 13, and a plurality of oil holes 15 are opened on the outside of the ball 14, and the oil holes 15 can throw out the lubricating oil. The right side of the steel pipe 19 contacts the left side of the steel pipe cover plate 28, and the steel pipe cover plate 28 can prevent the rosin water inside the steel pipe 19 from being exposed. The left side of the steel pipe 19 contacts the front end of the steel pipe cover plate 13, and the steel pipe cover plate 28 and the steel pipe cover plate 13 can prevent the rosin water inside the steel pipe 19 from being exposed. A special mechanism is used to lock the two ends of the steel pipe 19, combined with the design of pouring rosin water during the bending process, which effectively prevents deformation caused by stress concentration during the bending process. This design ensures the stability of the assembly surface throughout the entire processing process and avoids the problem of secondary deformation during subsequent machining;
[0035] The interior of the limiting groove 13 is fixedly connected with a sealing component that prevents multiple lubricating oils from leaking. The sealing component includes multiple fixing rings 16. The outside of the fixing ring 16 is fixedly connected to the inside of the limiting groove 13. The fixing ring 16 can be fixed inside the limiting groove 13. The top of the fixing ring 16 is fixedly connected with a spring 17. At the same time, the spring 17 on the top of the fixing ring 16 has an extrusion effect. The top of the spring 17 is fixedly connected with a sealing gasket 18. The spring 17 can squeeze the sealing gasket 18 so that the sealing gasket 18 can be inside the limiting groove 13 to prevent the lubricating oil from leaking. The outside of the sealing gasket 18 contacts the inner top of the limiting groove 13, and the inner top of the limiting groove 13 has a limiting groove to prevent the sealing gasket 18 from falling off. The material of the sealing gasket 18 is rubber. The rubber material can enable the sealing gasket 18 to achieve a filling effect in the inside of the limiting groove 13, and then achieve a tight fit.
[0036] The pipe bending tooling, through the high-precision bending mechanism and fixture design, can ensure that the bending angle is controlled between 89° and 90°, significantly improving the processing accuracy of the bent pipe and meeting the high-standard assembly requirements. At the same time, by reducing the welding process and related labor costs and adopting a one-time bending process, material waste and production costs are reduced. At the same time, the modular design of the tooling makes maintenance and replacement of parts more convenient, further reducing long-term operating costs. Through high-precision bending and anti-deformation design, the strength and stability of the final product are significantly improved, reducing after-sales service and rework caused by product quality problems, improving customer satisfaction, and the tooling is not only suitable for the manufacture of five-axis machining equipment, but can also be widely used in multiple industries such as automobiles, aerospace, and construction, with strong market adaptability and promotion value.
[0037] Working principle: When the steel pipe 19 needs to be processed, the folding plate 1 plays a bending function. Through the left and right levers, the head and the bending part of the steel pipe 19 are subjected to force at the same time, which plays a role in bending and preventing deformation. Secondly, the steel pipe 19 is placed inside one end of the steel pipe guide mechanism 5, and the deformation of the steel pipe is guided by the profiling groove. At the same time, the upper baffle 4 is designed to prevent the steel pipe 19 from moving up and down. At the same time, by adding rosin water to the inside of the steel pipe 19, deformation caused by stress concentration during the bending process is effectively prevented. This design ensures the stability of the assembly surface during the entire processing process and avoids the problem of secondary deformation during subsequent machining. After adding rosin water, the two ends of the steel pipe 19 are sealed with steel pipe cover plate 2 8 and steel pipe cover plate 1 3 to prevent the internal liquid from flowing out. At this time, the slider 2 is moved by pushing the folding plate 1, and the slider 2 will be restricted by the moving groove 9 during the movement. The shape of the moving groove 9 is a right angle, and the steel pipe 19 is placed in the extrusion groove 12 when it is in a straight shape. When the folding plate 1 moves, it can squeeze the steel pipe 19, causing the steel pipe 19 to bend and then complete the bending. The steel pipe 19 is locked by the locking mechanism 7 to prevent internal deformation.
[0038] When it is necessary to apply lubricating oil to the surface of the steel pipe 19, the lubricating oil is first placed inside the limiting groove 13, and the lubricating oil can be contaminated by the ball 14 inside the limiting groove 13, and a plurality of oil holes 15 are opened on the surface of the ball 14, through which the lubricating oil enters the inside of the oil holes 15, and when the steel pipe 19 is bent, the ball 14 can apply the internal lubricating oil to the surface of the steel pipe 19. During processing, the surface of the lubricating oil steel pipe 19 forms a smooth film, which greatly reduces the friction coefficient between the steel pipe 19 and the bending mold, which makes the bending process smoother and reduces the force required for bending. At the same time, the lubricating oil inside the limiting groove 13 will spill out during bending, and the lubricating oil can be controlled inside the limiting groove 13 by the sealing gasket 18, and the limiting groove 13 at the top end of the limiting groove 13 can support the sealing gasket 18 through the spring 17, so that the sealing gasket 18 is in a tight state, thereby achieving a better sealing effect.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
