Description

Technical Field

[0001] This utility model relates to the technical field of cane manufacturing equipment, and in particular to a punching device for an irregularly shaped nine-hole tube. Background Technology

[0002] Currently, canes are a walking aid, typically used to help people with mobility impairments walk.

[0003] The current punching process for cane tubing requires transferring the tubing between multiple punching machines (first positioning → transfer to the side punching station → then transfer to the vertical punching station). Each transfer results in the loss of the positioning reference, and the cumulative tolerance leads to out-of-tolerance positional accuracy of the nine holes and the side holes, resulting in a low finished product qualification rate. Furthermore, side punching and vertical punching must be performed in separate steps: first, the tubing is fixed to the side punching die manually or by a robot to complete the single-sided punching; then, it is re-clamped before vertical punching. The process changeover and idle time account for a high proportion of the time, and with traditional fixtures that only rely on external clamping of the tubing wall, radial slippage or torsion of the tubing is prone to occur during vertical punching.

[0004] Therefore, a punching device for irregularly shaped nine-hole tubes is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a punching device for irregularly shaped nine-hole tubes. This invention innovatively decouples the constraints of traditional multi-station processing, achieving simultaneous three-dimensional spatial operation of positioning, side punching, and vertical punching. While the positioning plug fixes the inside of the tube, side punches A and B punch horizontally, simultaneously combining with the upper and lower punches in the upper and lower dies of the stamping mechanism. This completes the processing of nine main holes and side holes in a single stroke.

The aluminum tube orientation device 2, conveying device, control device 6, and punching device 7 are all mounted on the worktable 3. A blanking slide 8 for receiving the tube 9 is provided on one side of the punching device 7. The blanking slide 8 is fixedly connected to the worktable 3. The aluminum tube orientation device 2 can adjust the axial angle of the tube 9 to ensure that the ribbed aluminum tube enters the subsequent work station in a preset direction. The punching device 7 in this invention includes a linear guide rail B701, a servo motor B702, a slide block B703, a positioning side punching mechanism 704, and a stamping mechanism. The worktable 3 in this invention serves as the supporting base of the entire machine, integrating the aluminum tube orientation, conveying, chamfering, and punching devices 7 to ensure the spatial positioning accuracy of each work station.

[0047] The conveying device of this utility model includes a conveying frame 4, which is fixedly connected to the workbench 3. Multiple pneumatic grippers 401 for gripping and conveying the tubes 9 are installed on the conveying frame 4. The oriented aluminum tubes can be gripped by the pneumatic grippers 401 and transferred to the chamfering station and the punching station in sequence.

[0048] In this invention, the linear guide rail B701 is fixedly mounted on the workbench 3. The servo motor B702 is connected to one side of the linear guide rail B701.

The push frame 7044 is disposed on the positioning seat 7043, and a positioning plug 704 for positioning and inserting the pipe 9 is mounted on the push frame 7044. 5. And the side punch assembly; the side punch assembly includes a side push block 704412 and a middle push block 70441. The side push block 704412 is fixedly connected to the left and right sides of the push frame 7044, and the middle push block 70441 is fixedly connected to the middle position of the push frame 7044. A side punch block A7046 is provided on one side of the side push block 704412, and a side punch block B7047 is provided on the left and right sides of the middle push block 70441. A side punch head A70461 is installed on the side punch block A7046, and a side punch head B70471 is installed on the side punch block B7047. The side punch head A70461 and the side punch head B70471 are respectively located on the left and right sides of the positioning plug 7045, and the side punch head A70461 and the side punch head B70471 are arranged opposite to each other. The hydraulic cylinder A7041 and push rod 7042 provide horizontal thrust to drive the push frame 7044 to move as a whole. The positioning plug 7045 can be inserted into the inner hole of the tube 9 to form radial rigid support for the tube 9 and prevent displacement of the tube 9 during punching. The side punching assembly of this utility model (including side push block 704412, middle push block 70441 + side punching block A7046, side punching block B7047) can decompose the thrust of the hydraulic cylinder A7041 into multi-directional horizontal punching force. When the push frame 7044 is driven by the hydraulic cylinder A7041, the middle push block 70441 and the side push block 704412 move simultaneously. The middle push block 70441 inserts between the two side punching blocks B7047, pushing the side punching blocks B7047 apart so that the two side punching blocks B7047 move outward. At the same time, the side push block 704412 drives the side punching block A7046 to move inward. The side punching head A70461 and the side punching head B70471 punch holes on the left and right sides of the pipe 9.

[0049] The stamping mechanism in this invention is located on one side of the positioning side stamping mechanism 704. The stamping mechanism is used to simultaneously punch holes at the top and bottom of the tube 9. The stamping mechanism includes a lower die holder 705 and an upper die holder 710. The lower die holder 705 is fixedly mounted on the worktable 3. A lower die base 708 is provided on the lower die holder 705, and an upper die base 709 is provided above the lower die base 708. A hydraulic cylinder B706 is installed at the bottom of the lower die holder 705. The output end of the hydraulic cylinder B706 is driven and connected to a push rod 707. The push rod 707 is connected to the bottom of the lower die base 708. The components are interconnected; an upper mold frame 710 is provided above the lower mold frame 705, and an oil cylinder C711 is installed on the upper mold frame 710. A pressure rod 712 is driven and connected to the output end of the oil cylinder. The pressure rod 712 is connected to the upper mold base 709. In this utility model, an arc-shaped groove 7081 for placing the pipe 9 is opened on the lower mold base 708. Multiple lower punches 7091 are installed in the arc-shaped groove 7081. Multiple upper punches 7082 are installed at the bottom of the upper mold base 709. The positions of the upper punches 7082 and the lower punches 7091 correspond to each other. In this invention, the arc-shaped groove 7081 of the lower die base 708 fits the outer contour of the tube 9 and has a built-in lower punch 7091 (fixed type). The hydraulic cylinder C711 drives the pressure rod 712 to press down, thereby causing the upper die base 709 to move downward, which in turn causes the upper punch 7082 to move vertically to punch the top of the tube 9. At the same time, the hydraulic cylinder B706 drives the upper die base 709 to move upward, and the lower punch 7091 punches the bottom of the tube 9. This invention can perform upper and lower punching on the tube 9 in conjunction with side punching: the hydraulic cylinders A7041, B706 and C711 are synchronously triggered by the control device 6, which can realize the three-dimensional coordinated punching function of horizontal side punching + vertical counter punching.

[0050] The chamfering device 5 of this utility model includes a linear guide rail A501, a servo motor A502, a slide A503, a chamfering machine 504, and a support frame 506. The linear guide rail A501 and the support frame 506 are both fixedly connected to the workbench 3. The servo motor A502 is installed on one side of the linear guide rail A501. The slide A503 is slidably connected to the linear guide rail A501. The chamfering machine 504 is fixedly connected to the slide A503. This utility model can simultaneously chamfer both ends of the aluminum tube by chamfering the chamfering device 5, removing burrs and providing a guide bevel for punching.

[0051] The working principle of this utility model is as follows:

[0052] Tube 9 (aluminum tube) is conveyed from the automatic feeding device 1 to the aluminum tube orientation device 2. The orientation device 2 first selects the direction for the aluminum tube, then chamfers both ends of the ribbed aluminum tube and punches holes, completing the processing. The oriented aluminum tubes are then sequentially moved to subsequent workstations by a transport mechanism, where both sides are chamfered. Next, a punching die completes the processing of nine holes in one pass. The other side is also punched, ensuring the accurate relative position of each hole. The equipment utilizes automated orientation selection, rapid chamfering, and accurate one-pass punching to achieve stable processing and high efficiency.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
