Description

Technical Field

[0001] This utility model relates to the field of pipe bending technology, specifically to a pipe bending device for processing bicycle frames with anti-slip function. Background Technology

[0002] Pipe bending technology is a process that uses physical deformation to process straight pipes into bends of specific angles and shapes. It is widely used in pipeline systems, machinery manufacturing and other fields. The pipe bending device is the core equipment for realizing pipe bending. It applies pressure to the pipe through a mold and controls the deformation trajectory with a guide mechanism, so that the pipe bends according to the predetermined requirements. It can accurately control parameters such as bending angle and radius, ensuring processing accuracy and quality and improving production efficiency.

[0003] Chinese utility model patent CN216095760U discloses a pipe bending device and a pipe bending machine, which includes "a frame, a limiting member, and a pipe bending mechanism. The limiting member is set on the frame and abuts against one side of the heating tube for limiting. The pipe bending mechanism is set on the frame and located on the side of the limiting member away from the feeding direction of the heating tube. It includes a mold core, a moving mold wheel, and a first power component that drives the moving mold wheel to rotate around the axis of the mold core, with the mold core abutting against the side of the heating tube away from the limiting member. The moving mold wheel is rotatably connected to the first power component, and the heating tube is accommodated between the mold core and the moving mold wheel." However, this pipe bending device is difficult to effectively constrain the processing position of the pipe, requiring manual adjustment by the user. This can easily lead to displacement deviation of the pipe during processing, which not only reduces the dimensional accuracy of the product but also causes bending angle errors due to positional loss of control, thus directly affecting production quality and yield. Utility Model Content

[0004] The purpose of this invention is to provide a bending device for processing bicycle frames with anti-slip function, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending device for processing bicycle frames with anti-slip function, comprising a support assembly, a drive assembly fixedly installed at the bottom of the support assembly, and a limit assembly fixedly installed at the top of the support assembly; The support assembly includes a frame, a fixed bracket is slidably mounted on the bottom of the frame, and a first base is fixedly mounted on the top of the fixed bracket by welding. Four screws are threaded on the top of the first base, and a first nut is threaded on the outer surface of each screw. The drive assembly includes a motor that is fixedly mounted on the inner wall of a fixed bracket by welding. A rotating rod is rotatably mounted on the top of the motor, and the motor and the rotating rod constitute a rotating structure. A connecting arm is fixedly mounted on the outer surface of the rotating rod, a connecting rod is fixedly mounted on the top of the connecting arm, and a moving mold wheel is fixedly mounted on the outer surface of the connecting rod. The limiting component includes a second base that is fixedly installed on the top of the frame by welding. The top of the second base has a slot, and four threaded rods are fixedly installed on the top of the second base. A second nut is threaded onto the outer surface of each threaded rod, and the same cover plate is fitted onto the outer surface of each threaded rod.

[0006] The beneficial effects of this utility model are as follows: by tightening the second base and the cover plate with the threaded rod and the second nut, the pipe is clamped and the displacement of the pipe is restricted. At the same time, the rough surface strip on the inner wall of the second base and the cover plate can further prevent the clamped pipe from shifting during pipe bending, thereby reducing the processing accuracy and processing efficiency.

[0007] To provide stable support during pipe bending operations in the device: The configuration is further defined as follows: the first base and the frame are fixedly connected by screws and a first nut, and the frame, together with the fixed bracket, forms a support structure.

[0008] By adopting the above technical solution, the stability of the device during the pipe bending process is ensured, and support is provided for the device.

[0009] To minimize pipe damage during the bending process: A further configuration is provided: a membrane core is fixedly installed on the top of the rotating rod.

[0010] By adopting the above technical solution, the membrane core can minimize the damage to the outer surface of the tube caused by bending during the processing.

[0011] To limit pipe displacement and prevent processing deviations: The design further includes: five sets of rough-surface strips are fixedly installed on the inner walls of both the slot and the cover plate.

[0012] By adopting the above technical solution, several rough-surfaced strips fixedly installed on the inner wall of the slot and cover plate can prevent the pipe from sliding during processing.

[0013] To achieve the constraint of pipe materials: The second base and the cover plate are further configured to form a clamping structure via a threaded rod and a second nut.

[0014] By adopting the above technical solution, the pipe placed between the cover plate and the second base can be clamped and held by the threaded rod and the second nut to limit its displacement, and the rough surface belt can be used to prevent it from sliding.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0019] Please see Figures 1 to 4 A bending device for processing bicycle frames with anti-slip function includes a support component 1, a drive component 2 fixedly installed at the bottom of the support component 1, and a limit component 3 fixedly installed at the top of the support component 1. The support component 1 includes a frame 11, a fixed bracket 12 is slidably mounted on the bottom of the frame 11, and a first base 13 is fixedly mounted on the top of the fixed bracket 12 by welding. Four screws 14 are threaded on the top of the first base 13, and a first nut 15 is threaded on the outer surface of each screw 14. The drive assembly 2 includes a motor 21 that is fixedly installed on the inner wall of the fixed bracket 12 by welding. A rotating rod 22 is rotatably installed on the top of the motor 21, and the motor 21 and the rotating rod 22 form a rotating structure. A connecting arm 23 is fixedly installed on the outer surface of the rotating rod 22. A connecting rod 24 is fixedly installed on the top of the connecting arm 23. A moving mold wheel 25 is fixedly installed on the outer surface of the connecting rod 24. The limiting component 3 includes a second base 31 that is fixedly installed on the top of the frame 11 by welding. The top of the second base 31 has a slot 32. Four threaded rods 34 are fixedly installed on the top of the second base 31. A second nut 35 is threadedly installed on the outer surface of each threaded rod 34. The same cover plate 36 is fitted on the outer surface of each threaded rod 34.

[0020] In this embodiment, as Figure 2 As shown, the first base 13 and the frame 11 are fixedly connected by screws 14 and first nuts 15, and the frame 11, together with the fixed bracket 12, forms a support structure.

[0021] In this embodiment, as Figure 3 As shown, a membrane core 26 is fixedly installed on the top of the rotating rod 22.

[0022] In this embodiment, as Figure 4 As shown, five sets of rough-surface strips 33 are fixedly installed on the inner walls of both the slot 32 and the cover plate 36.

[0023] In this embodiment, as Figure 4 As shown, the second base 31 and the cover plate 36 form a clamping structure through the threaded rod 34 and the second nut 35.

[0024] The working process of this bicycle frame bending device with anti-slip function is as follows: First, the user needs to place the pipe to be processed inside the slot 32, then pass the pipe through the gap between the moving mold wheel 25 and the diaphragm core 26, and then adjust its length. After the length is adjusted, the user can put the cover plate 36 on the outer surface of the four threaded rods 34, and then tighten the second base 31 and the cover plate 36 by rotating the four second nuts 35. With the rough surface strip 33 fixedly installed on the inner wall of the second base 31 and the cover plate 36, the pipe clamped between the second base 31 and the cover plate 36 is prevented from making errors due to sliding displacement. Then, the motor 21 is started by an external electrical control device. The motor 21 will drive the rotating rod 22 to rotate. The connecting arm 23, which is fixedly installed on the outer surface of the rotating rod 22, will also rotate with the rotating rod 22. The connecting rod 24 is fixedly installed on the top of the connecting arm 23, and the moving mold wheel 25 is fixedly installed on the outer surface of the connecting rod 24. Therefore, the motor 21 will drive the moving mold wheel 25 to rotate together. In conjunction with the membrane core 26 fixedly installed on the top of the rotating rod 22, the damage to the pipe is minimized during the pipe bending process. After the device has finished processing, the user only needs to rotate the second nut 35, which is threaded on the outer surface of each threaded rod 34, in the opposite direction to separate the second base 31 and the cover plate 36, thereby taking out the pipe between the second base 31 and the cover plate 36.
