Description
Technical Field
[0001] This application relates to the field of automotive pipe bending technology, and in particular to an adjustable spacing limiting device for a pipe bending machine. Background Technology
[0002] Automotive piping is an important component of automobiles. Due to the compact structure of the front compartment, automotive piping needs to make way for other structures. Therefore, during automobile assembly, automotive piping, such as oil pipes, needs to be processed into different angles using bending dies or bending equipment according to different vehicle models and different layout structures to meet the requirements and placement of the parts in use.
[0003] The pipe bending machine disclosed in the prior art includes a mounting plate and a bending unit. Two bending wheel bodies are slidably connected to the mounting plate, and the bending wheel bodies have semi-grooves. The semi-grooves on the two bending wheel bodies form a pipeline groove, through which the pipe passes and extends into the pipeline groove. The bending unit is located below the bending wheel bodies and is used to make the pipe wrap around and fit into the pipeline groove. It is used to drive the bending rod to rotate. The bending unit includes a bending rod and a bending drive assembly. The bending rod has an arc-shaped groove adapted to the outer diameter of the pipe on the side near the bending wheel body. The rotation axis of the bending rod is coaxial with the central axis of the bending wheel body. The bending drive assembly is located below the bending rod and is connected to the bending rod. It is used to drive the bending rod to rotate and apply force to the pipe through the inner wall of the arc-shaped groove, so that the pipe wraps around the inner wall of the pipeline groove, thus completing the bending action.
[0004] When the aforementioned pipe bending machine bends automotive pipes, the workers install the pipes into the pipe trench, and then use the bending unit to drive the pipes to fit into the pipe trench and bend them. However, since the size of the pipe trench is fixed, it is impossible to bend automotive pipes of different diameters, which affects the processing effect of the pipe bending machine. Utility Model Content
[0005] To improve the processing effect of pipe bending machines, this application provides an adjustable spacing limit device for pipe bending machines.
[0006] This application provides an adjustable spacing limiting device for a pipe bending machine, which adopts the following technical solution: An adjustable spacing limiting device for a pipe bending machine includes a mounting plate and a limiting mechanism; The limiting mechanism includes a drive assembly, a bending wheel guide rail, and two bending wheel bodies; The bending wheel guide rail is mounted on the mounting plate, and the length direction of the bending wheel guide rail is parallel to the axial direction of the bending wheel body; The two bending wheel bodies are coaxially arranged, and the bending wheel bodies are slidably connected to the bending wheel guide rail; The main body of the bending wheel is provided with a semi-circular groove, which is located on one side of the two main bodies of the bending wheel that are close to each other, and the semi-circular grooves on the two main bodies of the bending wheel form a pipeline groove. The mounting plate is provided with a through groove, which is positioned directly opposite the pipeline groove. The drive assembly is mounted on the mounting plate and is used to drive the two bending wheel bodies to move closer or further apart.
[0007] By adopting the above technical solution, during pipe bending, the drive assembly is adjusted to drive the bending wheel bodies away from each other, and the bending wheel bodies slide along the bending wheel guide rail until the maximum distance between the two semi-circular grooves is greater than the diameter of the pipe. Then, the worker inserts the pipe through the through groove into the pipeline groove. The drive assembly is then adjusted again to drive the bending wheel bodies closer to each other, and the bending wheel bodies slide along the bending wheel guide rail until the sidewalls of the two bending wheel bodies are tightly fitted with the pipe, thus limiting the pipe. Then, the bending unit of the pipe bending machine is used to bend the pipe. The designed pipe bending machine uses an adjustable spacing limiting device. Through the two bending wheel bodies with adjustable spacing, it is convenient to limit and clamp pipes of different diameters. Combined with the bending unit, it can bend pipes of different diameters, improving the processing effect of the pipe bending machine.
[0008] Optionally, the drive assembly includes a finger cylinder, a guide rail, two guide blocks, and two linkage components; The finger cylinder is mounted on the mounting plate; The two guide blocks are respectively mounted on the chuck of the finger cylinder, and the guide blocks are located between the finger cylinder and the bending wheel body; The guide rail is mounted on the mounting plate, the length direction of the guide rail is parallel to the length direction of the curved wheel guide rail, and the guide block is slidably connected to the guide rail; The guide block and the bending wheel body are connected by the linkage component.
[0009] By adopting the above technical solution, during pipe bending, the finger cylinder is adjusted, and the two clamps of the finger cylinder drive the two guide sliders to move away from each other. The guide sliders slide along the guide rail, and through the linkage, drive the bending wheel body to move until the maximum distance between the semi-circular grooves of the two bending wheel bodies is greater than the diameter of the pipe. Then, the worker inserts the pipe through the through groove into the pipeline trench. The finger cylinder is then adjusted again, and the two clamps of the finger cylinder drive the two guide sliders to move closer to each other. The guide sliders slide along the guide rail, and through the linkage, drive the bending wheel body to move until the sidewalls of the two bending wheel bodies are tightly fitted with the pipe, achieving pipe limiting. This is then combined with the bending unit of the pipe bending machine to bend the pipe. The designed drive component facilitates the application of force to the bending wheel body, allowing the two bending wheel bodies to move closer or further apart, thereby achieving limiting clamping of pipes of different diameters. Simultaneously, the two guide sliders, in conjunction with the two bending wheel bodies, achieve multi-point limiting of the pipe, improving the pipe limiting effect.
[0010] Optionally, the linkage component includes a linkage shaft, which is mounted on the guide block. The bending wheel body has a linkage groove for inserting the linkage shaft, and the length direction of the linkage shaft is parallel to the clamping direction of the finger cylinder.
[0011] By adopting the above technical solution and designing the linkage groove, the guide slider drives the linkage shaft to move synchronously during the movement of the guide slider. Since the linkage shaft is inserted into the linkage groove, the linkage shaft drives the bending wheel body to move, realizing the mutual approach of the two bending wheel bodies, thereby realizing the limiting clamping of pipes with different diameters.
[0012] Optionally, the length direction of the linkage groove is parallel to the length direction of the curved wheel guide rail, and the length of the linkage groove is greater than the diameter of the linkage shaft.
[0013] By adopting the above technical solution, the length of the designed linkage groove is greater than the diameter of the linkage shaft, so that the guide slider drives the linkage shaft to move synchronously during the movement of the guide slider. Since the linkage shaft is inserted into the linkage groove, the linkage shaft slides along the linkage groove. When the linkage shaft slides to the point where it abuts against the bending wheel body, the linkage shaft drives the bending wheel body to move, so that the two bending wheel bodies move closer to each other, thereby realizing the limiting clamping of pipes with different diameters, ensuring the movement margin of the bending wheel body, and ensuring that the distance between the two guide sliders is greater than the minimum distance between the two bending wheel bodies.
[0014] Optionally, the drive assembly includes a compression spring, the two ends of which are respectively connected to the bend wheel body on opposite sides.
[0015] By adopting the above technical solution, the designed compression spring facilitates the application of force to the two bending wheel bodies, causing the two bending wheel bodies to tend to move away from each other, thereby facilitating the reset of the two bending wheel bodies.
[0016] Optionally, at least one of the bending wheel bodies is provided with a mounting groove, the mounting groove is located on one side of the two bending wheel bodies that are close to each other, the mounting groove is arranged along the length direction of the bending wheel guide rail, and one end of the compression spring extends into the mounting groove.
[0017] By adopting the above technical solution, the designed mounting groove facilitates the installation of the compression spring. At the same time, it facilitates reducing the minimum distance between the two bending wheel bodies, expanding the applicability of the adjustable spacing limit device for pipe bending machines.
[0018] Optionally, the two guide blocks are arranged in an arc shape at the corners near the pipeline groove, and the two guide blocks are symmetrically distributed about the pipeline groove.
[0019] By adopting the above technical solution, the corner of the guide slider is set in an arc shape, which makes it easier to increase the contact area between the guide slider and the pipeline, thereby increasing the friction between the guide slider and the pipeline and improving the limiting effect of the pipeline.
[0020] Optionally, the distance between the two guide blocks is greater than the minimum distance between the two bending wheel bodies, and the distance between the two guide blocks is less than the maximum distance between the two bending wheel bodies.
[0021] By adopting the above technical solution, the distance between the two guide blocks is greater than the minimum distance between the two bending wheel bodies and less than the maximum distance between the two bending wheel bodies, which facilitates the limiting clamping of the pipeline and improves the limiting effect of the pipeline.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The designed pipe bending machine uses an adjustable spacing limiting device. The limiting mechanism facilitates the application of force to the bending wheel body, allowing the two bending wheel bodies to move closer or further apart, thereby achieving limiting and clamping of pipes of different diameters. At the same time, two guide sliders cooperate with the two bending wheel bodies to achieve multi-point limiting of the pipe, improving the limiting effect of the pipe. In addition, it works with the bending unit to bend pipes of different diameters, improving the processing effect of the pipe bending machine. The compression spring facilitates the application of force to the two bending wheel bodies, causing the two bending wheel bodies to tend to move away from each other, thus facilitating the reset of the two bending wheel bodies.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0027] This application discloses an adjustable spacing limiting device for a pipe bending machine.
[0028] Reference Figure 1 and Figure 2 An adjustable spacing limiting device for a pipe bending machine includes a mounting plate 1 and a limiting mechanism 2. The limiting mechanism 2 includes a drive assembly 21, a bending wheel guide rail 22, and two bending wheel bodies 23. The bending wheel guide rail 22 is mounted on the mounting plate 1, and its length direction is parallel to the axial direction of the bending wheel body 23. The two bending wheel bodies 23 are coaxially arranged, and the bending wheel bodies 23 are slidably connected to the bending wheel guide rail 22. In this embodiment, the bending wheel guide rail 22 is fixed to the mounting plate 1 by countersunk bolts to prevent the countersunk bolts from protruding from the bending wheel guide rail 22, ensuring that the bending wheel bodies 23 slide along the bending wheel guide rail 22. A semi-circular groove 24 is formed on the bending wheel body 23, located on the side of the two bending wheel bodies 23 that is close to each other, and the semi-circular groove 24 is located on the side of the bending wheel body 23 that is close to the drive assembly 21. The semi-circular grooves 24 on the two bending wheel bodies 23 form a pipeline groove 25. Figure 1 The mounting plate 1 has a through groove 11, which is directly opposite the pipeline groove 25, so that the pipeline can pass through the pipeline groove 25. The drive assembly 21 is mounted on the mounting plate 1 and is used to drive the two bending wheel bodies 23 to move closer or further apart, so as to cooperate with the bending unit of the pipe bending machine to bend the pipeline. In addition, when the bending wheel body 23 in this application is connected to the external bending unit, the drive motor of the bending unit is coaxially connected to the bending wheel body 23.
[0029] Reference Figure 2and Figure 3 The drive assembly 21 includes a finger cylinder 211, a guide rail 212, a compression spring 216, two guide sliders 213, and two linkages 214. The finger cylinder 211 is mounted on the mounting plate 1. In this embodiment, the finger cylinder 211 is fixed to the mounting plate 1 by bolts. The two guide sliders 213 are respectively mounted on the clamps of the finger cylinder 211, so that the two guide sliders 213 can be moved closer or further apart by the finger cylinder 211, and the guide sliders 213 are located between the finger cylinder 211 and the bending wheel body 23. The guide rail 212 is mounted on the mounting plate 1. The length direction of the guide rail 212 is parallel to the length direction of the bending wheel guide rail 22, and the guide sliders 213 are slidably connected to the guide rail 212. In this embodiment, the guide rail 212 is fixed to the mounting plate 1 by countersunk bolts. To prevent the countersunk bolts from protruding from the guide rail 212, the guide slider 213 is ensured to slide along the guide rail 212. Furthermore, the corners of both guide sliders 213 near the pipeline groove 25 are rounded, and the two guide sliders 213 are symmetrically distributed about the pipeline groove 25. The distance between the two guide sliders 213 is greater than the minimum distance between the two bending wheel bodies 23, and less than the maximum distance between the two bending wheel bodies 23. This facilitates multi-point limiting and clamping of the pipeline by the two guide sliders 213 and the two bending wheel bodies 23. Simultaneously, the smaller distance between the two guide sliders 213 and the maximum distance between the two bending wheel bodies 23 facilitates limiting and clamping of the diameter-changing parts of the variable-diameter pipeline, thereby increasing the applicability of the adjustable-gap limiting device for the pipe bending machine.
[0030] Reference Figure 2 and Figure 4The guide slider 213 and the bending wheel body 23 are connected by a linkage 214. The linkage 214 includes a linkage shaft 2142, which is mounted on the guide slider 213. In this embodiment, the linkage shaft 2142 and the guide slider 213 are fixedly connected to facilitate synchronous movement of the linkage shaft 2142 and the guide slider 213. The bending wheel body 23 has a linkage groove 2141 for inserting the linkage shaft 2142. The length direction of the linkage shaft 2142 is parallel to the clamping direction of the finger cylinder 211, and the length direction of the linkage groove 2141 is parallel to the length direction of the bending wheel guide rail 22. The length of the linkage groove 2141 is greater than the diameter of the linkage shaft 2142. In this embodiment, the diameter of the linkage shaft 2142 is set to D, and the length of the linkage groove 2141 is set to L. L≧3D; The two ends of the compression spring 216 are respectively connected to the side of the bending wheel body 23 that is close to each other. At least one of the bending wheel bodies 23 is provided with a mounting groove 215. In this application, the mounting groove 215 can be one or two, as long as the compression spring 216 can be installed. In this embodiment, the mounting groove 215 is set as one, and the mounting groove 215 is located on the side of the bending wheel body 23 that is close to the other bending wheel body 23. The mounting groove 215 is set along the length direction of the bending wheel guide rail 22, and one end of the compression spring 216 extends into the mounting groove 215 to reduce the extension amount of the compression spring 216, so as to reduce the minimum distance between the two bending wheel bodies 23 and expand the application range of the adjustable spacing limit device for the pipe bending machine.
[0031] The implementation principle of the adjustable spacing limiting device for the pipe bending machine in this application embodiment is as follows: When bending the pipe, the finger cylinder 211 is adjusted, and the two clamps of the finger cylinder 211 drive the two guide sliders 213 to move away from each other. The guide sliders 213 slide along the guide rail 212, and the guide sliders 213 drive the linkage shaft 2142 to move synchronously. Since the linkage shaft 2142 is inserted into the linkage groove 2141, the linkage shaft 2142 slides along the linkage groove 2141. When the linkage shaft 2142 abuts against the bending wheel body 23, the linkage shaft 2142 drives the bending wheel body 23 to move until the maximum distance between the semi-arc grooves 24 of the two bending wheel bodies 23 is greater than the diameter of the pipe. Then, the operation... Personnel insert the pipe through the through groove 11 into the pipe groove 25, then adjust the finger cylinder 211. The two clamps of the finger cylinder 211 drive the two guide sliders 213 to move closer to each other. The guide sliders 213 slide along the guide rail 212, and the guide sliders 213 drive the linkage shaft 2142 to move synchronously. Since the linkage shaft 2142 is inserted into the linkage groove 2141, the linkage shaft 2142 slides along the linkage groove 2141. When the linkage shaft 2142 abuts against the bending wheel body 23, the linkage shaft 2142 drives the bending wheel body 23 to move until the side walls of the two bending wheel bodies 23 are tightly fitted with the pipe, realizing the limit of the pipe. Then, the bending unit of the pipe bending machine is used to bend the pipe.
[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
