Description

Technical Field

[0001] This application relates to the field of pipe bending equipment technology, and in particular to a front feeding mechanism for a pipe bending machine. Background Technology

[0002] An automotive pipe bending machine is a specialized piece of equipment used in the automotive manufacturing and repair industry. Its main function is to bend metal pipes into specific shapes and angles to meet the processing requirements of automotive parts. Its working principle is primarily achieved through the coordinated action of a hydraulic system, a control system, and bending dies. The hydraulic system provides power, the control system controls the bending angle and precision, and the bending die determines the shape of the bent pipe. During operation, the pipe is placed inside the machine, and the bending machine's dies and servo system ensure the accuracy and stability of the bending process.

[0003] An integrated head for a pipe bending machine is disclosed in the prior art, comprising a base plate, a rotating disk rotatably connected to the base plate, the rotating disk being coaxial with and offset from a heating cylinder, and a rotating unit connected to the base plate, the rotating unit being connected to the rotating disk for driving the rotating disk to rotate; a bending assembly disposed on the base plate near the rotating disk, the bending assembly being used to bend pipes and to clamp and release the pipes; and a telescopic unit, one end of the telescopic unit being connected to the bending assembly and the other end being connected to the rotating disk, for driving the bending assembly toward or away from the rotating disk.

[0004] Regarding the aforementioned technologies, after the pipeline loses the positional constraint of the rear feeding unit, it needs to be clamped by the bending assembly, then pulled out of the heating cylinder by the telescopic unit, and then the bending assembly is retracted to complete the bending process of the pipeline. The telescopic unit mainly includes a telescopic cylinder, a fixing bar, and a sliding bar to achieve sliding guidance. However, due to the large mass of the bending assembly, in actual use, the unilateral load-bearing can cause the bending unit to vibrate, affecting the bending quality of the automotive pipeline. Utility Model Content

[0005] In order to reduce the impact of bending unit vibration on the bending quality of automotive pipes while completing the pre-feeding of the pipe, this application provides a pre-feeding mechanism for a pipe bending machine.

[0006] The technical solution for the front feeding mechanism of a pipe bending machine provided in this application is as follows:

[0007] A front feeding mechanism for a pipe bending machine includes a rotary table and a bending assembly, and further includes:

[0008] At least three guide support rods are provided, and the guide support rods are perpendicularly connected to the rotating disk.

[0009] A connecting plate with a clearance hole is provided. The connecting plate is connected to the bending assembly. The guide support rod passes through the connecting plate and is slidably connected to the guide support rod.

[0010] A driving component, which is connected to the bending assembly and the connecting disc, to allow the connecting disc to slide axially along the guide support rod.

[0011] By adopting the above technical solution, when the automotive pipe on the coil separates from the coil itself, the automotive pipe inside the heating cylinder loses the conveying from the rear feeding unit. At this time, a front feeding method is required. That is, the automotive pipe is first clamped and fixed by the bending assembly, and then the driving component applies force to the connecting plate, causing the connecting plate to slide along the axial direction of the guide support rod. While the connecting plate slides, it drives the automotive pipe to move through the bending assembly, thus realizing the front feeding of the automotive pipe. The designed front feeding mechanism of the pipe bending machine can realize the rotation of the bending assembly by means of the rotating plate, which can cooperate with the connecting plate and the guide support rod to realize the bending processing of the automotive pipe. The guide support rod can realize the stability of the connecting plate during horizontal lateral movement. The connecting plate can realize the connection of the bending assembly. The driving component can make the connecting plate slide along the axial direction of the guide support rod, avoiding the shaking caused by the weight of the bending assembly during movement, thus ensuring the quality of the automotive pipe bending processing.

[0012] In one specific implementation, multiple reinforcing ribs are connected between the connecting disc and the bending assembly.

[0013] By adopting the above technical solution, the designed reinforcing ribs can further improve the stability of the connection between the bending assembly and the connecting disc.

[0014] In one specific implementation, a position limiting frame is further included, the position limiting frame being located on the side of the connecting plate away from the rotating plate, and the position limiting frame being connected to the end of the guide support rod away from the rotating plate.

[0015] By adopting the above technical solution, the designed position limiting frame can connect and fix multiple guide support rods to form a whole, further ensuring the stability of the connecting plate during horizontal lateral movement.

[0016] In one specific implementation, the drive includes:

[0017] A drive shaft, the two ends of which are connected to the rotating disk and the position limiting frame respectively, and the axial direction of the drive shaft is consistent with the axial direction of the guide support rod;

[0018] Rotate the nut, which is threaded onto the drive shaft and rotatably connected to the connecting disc;

[0019] A drive motor is connected to the bending assembly, and the axial direction of the drive motor's rotation shaft is consistent with the axial direction of the guide support rod.

[0020] A timing belt is simultaneously fitted onto the rotating nut and the output shaft of the drive motor.

[0021] By adopting the above technical solution, the designed drive component can drive the rotating nut to rotate via a synchronous belt through a drive motor. The rotating nut, in conjunction with the transmission shaft, can realize the reciprocating movement of the connecting disc along the axial direction of the wire support rod, thereby achieving the horizontal lateral movement of the bending assembly.

[0022] In one specific implementation, the connecting plate is equipped with multiple linear bearings, and the guide support rod is disposed through the sliding cavity of the linear bearing.

[0023] By adopting the above technical solution, the designed linear bearing can reduce the resistance when the connecting disc slides along the axial direction of the guide support rod, and ensure the smoothness of the connecting disc during sliding.

[0024] In one specific implementation, a plurality of graphite copper sleeves are mounted on the connecting plate, and the guide support rod is disposed through the sliding cavity of the graphite copper sleeve.

[0025] By adopting the above technical solution, the designed graphite copper sleeve can reduce the resistance when the connecting plate slides along the axial direction of the guide support rod, and ensure the stability of the connecting plate during sliding.

[0026] In one specific implementation, the connecting plate is equipped with a plurality of ball splines, and the guide support rod is disposed through the sliding cavity of the ball splines.

[0027] By adopting the above technical solution, the designed ball spline can reduce the resistance when the connecting disc slides along the axial direction of the guide support rod, and ensure the stability of the connecting disc during sliding.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The designed front feeding mechanism of the pipe bending machine uses a rotating disc to cooperate with the connecting disc and guide support rod to realize the rotation of the bending assembly, thereby realizing the bending process of automotive pipes. The guide support rod can ensure the stability of the connecting disc during horizontal movement. The connecting disc can connect the bending assembly. The driving component can make the connecting disc slide along the axial direction of the guide support rod, avoiding vibration caused by the weight of the bending assembly during movement, thus ensuring the quality of automotive pipe bending.

[0030] 2. The designed front feeding mechanism of the pipe bending machine can drive the rotating nut to rotate via a synchronous belt through a drive motor. The rotating nut, in conjunction with the transmission shaft, can realize the reciprocating movement of the connecting plate along the axial direction of the guide rod, thereby realizing the horizontal lateral movement of the bending assembly.

[0031] 3. The designed front feeding mechanism of the pipe bending machine, through ball splines, can reduce the resistance when the connecting plate slides along the axial direction of the guide support rod and ensure the stability of the connecting plate during sliding.

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This application discloses a front feeding mechanism for a pipe bending machine.

[0038] Reference Figure 1 A front feeding mechanism for a pipe bending machine includes a rotating disk 1, a bending assembly 2, guide support rods 3, and a connecting disk 4. The rotating disk 1 is rotatably connected to the main body of the pipe bending machine, and the rotation axis of the rotating disk 1 is horizontally arranged. There are at least three guide support rods 3, which are welded or bolted to the rotating disk 1. The axis of the guide support rods 3 is horizontally arranged and perpendicular to the rotating disk 1. The multiple guide support rods 3 are distributed in a near-annular pattern to form a cavity for the heating cylinder to pass through. The connecting disk 4 has clearance holes for the heating cylinder to pass through. The guide support rods 3 pass through the connecting disk 4, and the connecting disk 4 can slide back and forth along the axial direction of the guide support rods 3. The bending assembly 2 is welded or bolted to the connecting disk 4.

[0039] Reference Figure 1Specifically, in order to improve the stability of the connection between the connecting disc 4 and the bending assembly 2, multiple reinforcing ribs 6 are also included. The reinforcing ribs 6 are welded and fixed to the connecting disc 4 or bolted together, and the reinforcing ribs 6 are welded and fixed to the bending assembly 2 or bolted together. In this application, the reinforcing ribs 6 can be cuboid, triangular, or other shapes, as long as they can enhance the connection stability between the connecting disc 4 and the bending assembly 2. In this embodiment, the reinforcing ribs 6 are triangular.

[0040] Reference Figure 1 In order to connect multiple guide support rods 3 to form a force-bearing whole, a position limiting frame 7 is also included. The position limiting frame 7 is located on the side of the connecting plate 4 away from the rotating plate 1, and the position limiting frame 7 is welded or bolted to the end of the guide support rod 3 away from the rotating plate 1.

[0041] Reference Figure 2 Furthermore, in order to improve the smoothness of sliding and reduce sliding resistance during the axial reciprocating sliding of the connecting disc 4 along the guide support rod 3, and to extend the service life of the guide support rod 3 and the connecting disc 4, a plurality of sliding friction damping components 8 are embedded in the connecting disc 4. The number of sliding friction damping components 8 is the same as the number of guide support rods 3. In some embodiments of this application, the sliding friction damping component 8 is preferably a linear bearing, and the guide support rod 3 is disposed through the sliding cavity of the linear bearing. In other embodiments of this application, the sliding friction damping component 8 is preferably a graphite copper sleeve, and the guide support rod 3 is disposed through the sliding cavity of the graphite copper sleeve. In other embodiments of this application, the sliding friction damping component 8 is preferably a ball spline, and the guide support rod 3 is disposed through the sliding cavity of the ball spline.

[0042] Reference Figure 3To drive the connecting disc 4 to slide back and forth along the axial direction of the guide support rod 3, the front feeding mechanism of the pipe bending machine also includes a driving component 5. The driving component 5 is connected to the bending assembly 2 and the connecting disc 4. Specifically, the driving component 5 includes a drive shaft 51, a rotating nut 52, a drive motor 53, and a synchronous belt 54. The drive shaft 51 passes through the connecting disc 4 and is offset from the connecting disc 4 along its own radial direction. The two ends of the drive shaft 51 are welded and fixed to the rotating disc 1 and the position limiting frame 7, respectively. The axial direction of the drive shaft 51 is consistent with the axial direction of the guide support rod 3. The rotating nut 52 is threaded. Connected to the drive shaft 51, and the rotating nut 52 is rotatably connected to the connecting plate 4. The drive motor 53 is bolted to the bending assembly 2, and the circumferential direction of the drive motor 53's rotating shaft is consistent with the axial direction of the guide support rod 3. The synchronous belt 54 is simultaneously sleeved on the rotating nut 52 and the output shaft of the drive motor 53, thereby transmitting the power of the drive motor 53 to the rotating nut 52. As the rotating nut 52 rotates, it rotates around the drive shaft 51 and moves along the axial direction of the drive shaft 51, while simultaneously driving the connecting plate 4 to move, thereby causing the connecting plate 4 to slide along the axial direction of the guide support rod 3.

[0043] The implementation principle of the front feeding mechanism of a pipe bending machine according to an embodiment of this application is as follows: When the automotive pipe on the material roll separates from the material roll itself, the automotive pipe in the heating cylinder loses the conveying of the rear feeding unit. At this time, a front feeding method is required. That is, the automotive pipe is first clamped and fixed by the bending assembly 2, and then the driving component 5 applies force to the connecting plate 4, so that the connecting plate 4 slides along the axial direction of the guide support rod 3. While the connecting plate 4 slides, it drives the automotive pipe to move through the bending assembly 2, thus realizing the front feeding of the automotive pipe. The rotating plate 1 can cooperate with the connecting plate 4 and the guide support rod 3 to realize the rotation of the bending assembly 2, thereby realizing the bending processing of the automotive pipe. The guide support rod 3 can realize the stability of the connecting plate 4 when moving horizontally. The connecting plate 4 can realize the connection of the bending assembly 2. The driving component 5 can make the connecting plate 4 slide along the axial direction of the guide support rod 3, avoiding the shaking caused by the weight of the bending assembly 2 during movement, thereby ensuring the quality of the automotive pipe bending processing.

[0044] 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.
