Description

Technical Field

[0001] This utility model relates to the field of bicycle tube processing technology, specifically a stamping and trimming device for bicycle tube processing. Background Technology

[0002] In the bicycle manufacturing industry, tubing is the basic raw material for core components such as frames and forks. Its processing precision directly determines the structural strength, riding safety and appearance quality of the bicycle. Among them, stamping and trimming is a key process in the bicycle tubing processing flow. The cut tubing ends need to be deburred and the edges smoothed to meet the precision requirements of subsequent welding, assembly and other processes. Currently, the stamping and trimming of round bicycle tubes in the industry is mostly done using traditional manual assistance or simple semi-automatic equipment. Traditional processing methods have obvious shortcomings. Tube fixing relies on manual hand-holding or simple clamps for positioning. Operators need to be in close contact with the stamping area, which not only poses a safety risk of accidental hand injury from the cutter, but also results in uneven manual fixing force and easy positional deviation, causing the tube to shake and misalign during the stamping process, ultimately causing deviations in trimming accuracy. Some tubes need to be reworked due to uneven edges, which seriously affects production efficiency. At the same time, existing equipment lacks a dedicated limiting structure, and clamps need to be changed frequently for bicycle tubes of different diameters. The adjustment process is cumbersome and has poor adaptability.

[0003] According to the description in the patent announcement (authorization announcement number: CN212527895U) of a polyethylene pipe edge cutting device, the polyethylene pipe edge cutting device includes a "first working box, a cutting box" etc., to realize the edge cutting work.

[0004] Regarding the above description, the applicant believes the following issues exist: This polyethylene pipe trimming device uses a first working box and a cutting box to perform trimming work. When in use, the device lowers the pressure plate by a first hydraulic jack, so that the pressure roller presses the pipe tightly above the conveyor belt. However, pressing by the pressure roller alone will cause the pipe to slip, and the pressure roller cannot make close contact with the pipe surface, affecting the stability during trimming. Therefore, this device needs to be improved. Utility Model Content

The second limiting frame is disposed on the top of the pipe body, and the cutter is disposed on the top of the pipe body.

[0007] Preferably, the top of the top plate is fixedly connected to the bottom of the protective cover, and the protective cover is located around the first hydraulic cylinder, so that the first hydraulic cylinder can be protected by the protective cover.

[0008] Preferably, the movable seat is slidably connected to the periphery of the column, the top of the workbench is provided with a cutting groove, and the bottom of the cutter is slidably connected to the cutting groove, so as to facilitate the cutting of the pipe body by the cutter.

[0009] Preferably, the inner sides of the first limiting frame and the second limiting frame are in contact with the outer periphery of the pipe body, and both the first limiting frame and the second limiting frame are V-shaped. The second limiting frame is slidably connected inside the first limiting frame, which facilitates the fixing of pipe bodies of different sizes through the first limiting frame and the second limiting frame.

[0010] Preferably, connecting arms are fixedly connected to the left and right sides of the second limiting frame. The connecting arms are slidably connected inside the fixed frame, and the bottom of the cutter is in contact with the top of the pipe body, so as to ensure the stability of the movement of the second limiting frame through the connecting arms.

[0011] Preferably, the cleaning mechanism includes a support frame, which is fixedly connected to the right side of the workbench.

[0012] Preferably, the first cleaning brush is slidably connected to the top of the workbench, and the second cleaning brush is slidably connected to the cutting groove, so that the debris on the top of the workbench and in the cutting groove can be cleaned by the first and second cleaning brushes, ensuring the quality of subsequent cutting.

[0013] Compared with the prior art, this utility model provides a stamping and trimming device for processing bicycle tubing, which has the following advantages: 1. This stamping and trimming device for bicycle tubing processing, through its set stamping and trimming mechanism, when it is necessary to stamp and trim bicycle round tubing, firstly, the tubing is placed inside the first limiting frame, so that the side to be trimmed is located at the bottom of the cutter and the top of the trimming groove. After placement, the second limiting frame is moved by the second hydraulic cylinder. When the second limiting frame moves, it will cause the connecting arm to slide inside the fixed frame, so that the second limiting frame is slidably connected to the inside of the first limiting frame. Under the action of the first and second limiting frames, the stability of the tubing body is guaranteed, avoiding the dangerous operation of fixing by hand.

[0014] 2. This stamping and trimming device for bicycle tubing processing, through a cleaning mechanism, places a debris collection device on the left side of the worktable during trimming. After the tubing is stamped and trimmed, a third hydraulic cylinder drives the moving table to move to the left. The first cleaning brush on the top of the inner side of the moving table can slide on the top of the worktable to remove residual metal debris from the worktable surface. The second cleaning brush at the bottom of the moving table can slide in the trimming groove to clean the debris accumulated in the trimming groove, avoiding debris accumulation that affects the quality of subsequent processing and reducing manual cleaning time. If residual metal debris in the processing area is not cleaned in time, it will cause the tubing surface to be scratched during subsequent processing. Attached Figure Description

The stamping and trimming mechanism 2 includes a worktable 21, which is fixedly connected to the left side of the control cabinet 1. A column 22 is fixedly connected to the top of the worktable 21, a top plate 23 is fixedly connected to the top of the column 22, a first hydraulic cylinder 24 is fixedly connected to the top of the top plate 23, a movable seat 26 is fixedly connected to the bottom of the first hydraulic cylinder 24, a cutter 27 is fixedly connected to the bottom of the movable seat 26, a support seat 25 is fixedly connected to the front side of the worktable 21, a first limiting frame 28 is fixedly connected to the top of the support seat 25, a pipe body 291 is provided inside the first limiting frame 28, connecting seats 29 are fixedly connected to the left and right sides of the support seat 25, a fixing frame 292 is fixedly connected to the top of the connecting seat 29, a second hydraulic cylinder 293 is fixedly connected to the top of the fixing frame 292, a second limiting frame 294 is fixedly connected to the bottom of the second hydraulic cylinder 293, the second limiting frame 294 is provided on the top of the pipe body 291, and the cutter 27 is provided on the top of the pipe body 291.

[0021] The top plate 23 is fixedly connected to the bottom of the protective cover 4, and the protective cover 4 is located around the first hydraulic cylinder 24, so that the first hydraulic cylinder 24 can be protected by the protective cover 4.

[0022] The movable seat 26 is slidably connected to the periphery of the column 22. The top of the workbench 21 is provided with a cutting groove, and the bottom of the cutter 27 is slidably connected to the cutting groove, so as to facilitate the cutting of the pipe body 291 by the cutter 27.

[0023] The inner sides of the first limiting frame 28 and the second limiting frame 294 are in contact with the outer periphery of the pipe body 291, and both the first limiting frame 28 and the second limiting frame 294 are V-shaped. The second limiting frame 294 is slidably connected to the inside of the first limiting frame 28, so as to fix the pipe body 291 of different sizes through the first limiting frame 28 and the second limiting frame 294.

[0024] The second limiting frame 294 is fixedly connected to the left and right sides with connecting arms 295. The connecting arms 295 are slidably connected inside the fixed frame 292. The bottom of the cutter 27 is in contact with the top of the pipe body 291, so that the second limiting frame 294 can be moved stably through the connecting arms 295. Example 2

[0025] Please see Figure 1-7 Furthermore, based on Embodiment 1, the cleaning mechanism 3 includes a support frame 31, which is fixedly connected to the right side of the workbench 21. A third hydraulic cylinder 32 is fixedly connected to the right side of the support frame 31, and a moving platform 33 is fixedly connected to the left side of the third hydraulic cylinder 32. A first cleaning brush 34 is fixedly connected to the top of the inner side of the moving platform 33, and a second cleaning brush 35 is fixedly connected to the bottom of the moving platform 33.

[0026] The first cleaning brush 34 is slidably connected to the top of the workbench 21, and the second cleaning brush 35 is slidably connected to the cutting groove. This allows the first cleaning brush 34 and the second cleaning brush 35 to clean the debris on the top of the workbench 21 and in the cutting groove, ensuring the quality of subsequent cutting.

[0027] In actual operation, when this device is used to perform stamping and trimming on bicycle round tubes, the tube body 291 is first placed inside the first limiting frame 28, so that the side to be trimmed is located at the bottom of the cutter 27 and the top of the trimming groove. After placement, the second limiting frame 294 is moved by the second hydraulic cylinder 293. When the second limiting frame 294 moves, it will cause the connecting arm 295 to slide inside the fixed frame 292, so that the second limiting frame 294 is slidably connected to the inside of the first limiting frame 28. Under the action of the first limiting frame 28 and the second limiting frame 294, the stability of the tube body 291 can be guaranteed, avoiding the dangerous operation of fixing by hand. Both are V-shaped and can be in close contact with the outer periphery of the tube body 291, effectively preventing the tube from shifting or shaking during the stamping and trimming process. After the debris collection device is placed on the left side of the workbench 21 and the pipe body 291 is fixed, the first hydraulic cylinder 24 drives the movable seat 26 to move the cutter 27 up and down. The movable seat 26 is slidably connected to the periphery of the column 22. The column 22 guides the movement of the movable seat 26 and can effectively limit the lateral displacement of the movable seat 26, so that the cutter 27 always moves in the vertical direction. When the cutter 27 contacts the side of the pipe body 291 that needs to be cut, it can be cut. The cutting groove opened on the top of the workbench 21 slides with the bottom of the cutter 27 to further ensure the stability of the cutting trajectory of the cutter 27 and improve the flatness and smoothness of the cut edge of the pipe body 291. Once the trimming is complete, the second hydraulic cylinder 293 can drive the second limit frame 294 to move upward, releasing the limit on the pipe body 291 and removing it. At the same time, the third hydraulic cylinder 32 drives the moving table 33 to move to the left. The first cleaning brush 34 on the top inner side of the moving table 33 can slide on the top of the worktable 21 to remove the metal debris remaining on the surface of the worktable 21. The second cleaning brush 35 at the bottom of the moving table 33 can slide in the trimming groove to clean the debris accumulated in the trimming groove, avoiding debris accumulation from affecting the subsequent processing quality and reducing manual cleaning time. If the metal debris remaining in the processing area is not cleaned in time, it will cause the pipe surface to be scratched during subsequent processing. In this application, the first hydraulic cylinder 24, the second hydraulic cylinder 293, and the third hydraulic cylinder 32 need to be connected to the same PLC controller in the control cabinet 1 to ensure the coordinated and automated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail here.
