Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, and in particular to a hydraulic pipe bending machine for excavators. Background Technology

[0002] Excavator hydraulic pipe bending machines have a wide range of applications and play a vital role in several key aspects of the excavator industry. In the manufacturing process, they are a powerful tool for mass-producing pipes that meet design specifications, precisely machining straight pipes and shaping pipe configurations to suit the connection needs of various hydraulic components, ensuring the efficient and coordinated operation of the hydraulic system. During maintenance and repair, whether it's routine wear and tear requiring pipe replacement or system upgrades necessitating layout adjustments, they can quickly create adaptable pipes according to the original or new plans, reducing downtime and maintenance costs, with significant advantages in field repair scenarios. In the experimental testing field, they are used to create samples, helping researchers study pipe performance under different working conditions, accumulating data and laying a solid foundation for optimizing excavator hydraulic system design.

[0003] Currently, electric hydraulic pipe bending machines are generally used when bending hydraulic lines of excavators. When working, the power is first turned on, and the hydraulic rod will work to generate thrust. Then, the pipe to be bent is placed on the corresponding bending mold, and the hydraulic line can be bent. After bending is completed, the equipment is operated to reset the bending components and hydraulic system, thereby realizing the bending of the hydraulic lines of excavators.

[0004] While the aforementioned equipment enables bending of excavator hydraulic lines, the fixed size of the bending die necessitates changing dies for pipes of different diameters, increasing cost and operational complexity. Frequent die changes are required when processing pipes of various diameters, wasting time and manpower. Therefore, an excavator hydraulic line bending machine is proposed to address these issues.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a hydraulic pipe bending machine for excavators, comprising a fixed block 3, a support block 5 fixedly connected to the top of the fixed block 3, a support component installed on the side of the support block 5 for supporting the hydraulic pipe during bending, a drive component fixedly connected inside the fixed block 3, an adjustment component installed at one end of the drive component, and a measuring component set on the outer periphery of the support component; the adjustment component includes a second movable block 15, the side of the second movable block 15 fixedly connected to the drive component, a cylinder 16 fixedly connected to the top of the second movable block 15, and a first movable block 14 fixedly connected to the output end of the cylinder 16. When the cylinder 16 works, it drives the first movable block 14 to move. An upper mold 8 and a lower mold 7 are fixedly connected to the sides of both the first movable block 14 and the second movable block 15. When the first movable block 14 moves, it drives the upper mold 8 to move accordingly, thereby adjusting the size of the mold, facilitating the bending of hydraulic pipes of different diameters, reducing the labor intensity of workers while improving work efficiency.

[0033] Reference Figure 1 and Figure 3 The support assembly includes a connecting block 1, the side of which is rotatably connected to the side of a support block 5. A rotating rod 4 is rotatably connected inside the support block 5. The outer periphery of the rotating rod 4 is fixedly connected to the inside of the connecting block 1. A connecting column 12 is slidably connected to the bottom of the connecting block 1. A connecting block 2 is fixedly connected to the bottom of the connecting column 12. A rotating rod 13 is rotatably connected to the outer periphery of the connecting column 12. There are two rotating rods 13, both of which are rotatably connected to the outer periphery of the connecting column 12. This allows the rotating rods 13 to rotate around the outer periphery of the connecting column 12, facilitating the rotation of the hydraulic pipeline along with the rotating rods 13 when the hydraulic pipeline is bent.

[0034] Reference Figure 1 , Figure 3 and Figure 4The driving component includes a hydraulic push rod 6, whose outer periphery is fixedly connected to the interior of the support block 5. The output end of the hydraulic push rod 6 is fixedly connected to the side of the moving block 15. When the hydraulic push rod 6 works, it drives the moving block 15 to move, thereby driving the upper mold 8 and the lower mold 7 to move under the action of the cylinder 16, thus extruding the hydraulic pipeline that needs to be bent, thereby bending the hydraulic pipeline. The measuring component includes a moving rod 11, with a measuring block 9 rotatably connected to the outer periphery of the moving rod 11. One end of the measuring block 9 is rotatably connected to the outer periphery of the connecting column 12. When the upper mold 8 and the lower mold 7 move, they push the moving rod 11 to move through the hydraulic pipeline that is being extruded, thereby causing the measuring block 9 to rotate on the outer periphery of the moving rod 11, thereby extruding the corresponding included angle according to the degree of bending of the hydraulic pipeline, and by measuring the included angle... The angle of the hydraulic pipeline bend can be determined by measurement, which facilitates angle measurement of the hydraulic pipeline during compression without removing it, thus simplifying the work and greatly improving efficiency. An elastic rope 17 is fixedly connected to the outer periphery of the moving rod 11, with one end of the rope 17 fixedly connected to the side of the connecting block 2. When the moving rod 11 moves, the elastic rope 17 is pulled up; when the hydraulic pipeline bends, the elastic rope 17 returns to its original position, thus moving the moving rod 11 back to its original position for the next measurement. A connecting plate 10 is fixedly connected to the side of the connecting block 2, with a groove 19 inside. A slider 18 is fixedly connected to the outer periphery of the moving rod 11. The groove 19 and slider 18 facilitate the movement of the moving rod 11, making the measurement work easier.

[0035] Working principle: First, when adjusting the mold for pipes of different diameters, cylinder 16 will work, driving moving block 14 to move up and down, and simultaneously driving upper mold 8 to move up and down, thereby adjusting the width between upper mold 8 and lower mold 7 according to the pipe diameter. Second, when it is necessary to read the bending angle of the hydraulic pipeline being bent, the bending hydraulic pipeline will push moving rod 11 according to the bending angle, thereby driving measuring block 9 to rotate around the outer periphery of connecting column 12. The bending angle of the hydraulic pipeline can be read by measuring the included angle between the two measuring blocks 9.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
