Description

Technical Field

[0001] This utility model relates to the field of glass guide rail punching technology, specifically to a bidirectional punching device for automotive door frame glass guide rails. Background Technology

[0002] Automotive window rails play a crucial role in automobiles. They not only provide sealing, waterproofing, dustproofing, sound insulation, and shock absorption, but also ensure the free and smooth raising and lowering of the door windows. To achieve both aesthetic appeal and proper window operation, the mounting position of the rails on the door must be extremely precise. Currently, the widely used automotive door frame window rails on the market are often manufactured using a punching and cutting process.

[0003] Chinese Patent Publication No. CN212703897U discloses a bidirectional punching device for automotive door frame glass guide rails, including a punching processing table, a first punching seat, and a second punching seat. A glass guide rail to be punched is placed on the horizontal centerline along the length direction of the upper surface of the punching processing table. A first groove and a second groove are respectively formed on both sides of the glass guide rail on the upper surface of the punching processing table. A first slider is slidably connected inside the first groove, and a first punching seat is welded onto the first slider. This bidirectional punching device for automotive door frame glass guide rails uses two punching seats, namely the first punching seat and the second punching seat, to punch the glass guide rail bidirectionally. Compared to the traditional method of using only one punching seat, this greatly improves the punching efficiency. Furthermore, it allows the glass guide rail to be punched to be subjected to forces from two opposing directions, which cancel each other out, ensuring the stability of the glass guide rail when fixed by the clamping mechanism.

[0004] The device uses two punching blades to cut the glass guide rails of car door frames in both directions. However, the debris generated during the cutting process accumulates on the top of the processing table, which not only interferes with subsequent punching operations but also requires workers to regularly clean the upper surface of the processing table to maintain a clean working environment. Utility Model Content

[0005] To address the aforementioned issues, a bidirectional punching device for automotive door frame glass guide rails is provided. The punching blade on the side wall of the movable seat can perform bidirectional punching on the sunroof guide rail. Simultaneously, a cleaning brush can collect the debris generated during the process through a drain hole into the inside of the collection drawer, preventing the top of the punching seat from pushing out a large amount of debris, which would affect subsequent punching operations.

[0006] To address the problems of existing technologies, this utility model provides a bidirectional punching device for automotive door frame glass guide rails, including a punching base. A support block is provided on one side of the top of the punching base. A positioning component for positioning the sunroof guide rail is movably disposed inside the support block. Screws are rotatably disposed at both ends of the side wall of the support block. A movable seat is provided on the external thread of the screw. A connecting block is provided on the side wall of the movable seat. A punching blade for punching the sunroof guide rail is disposed on the side wall of the connecting block. Cleaning brushes for cleaning debris are provided on both sides of the punching blade. Multiple drainage holes for debris to fall off are opened on the top of the punching base. A drive motor is disposed on the top of the other side of the punching base. The output shaft of the drive motor is connected to one of the screws through a coupling.

[0007] Preferably, both screws are provided with a timing pulley on their exterior, and the two timing pulleys are connected by a timing belt drive.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model provides:

[0024] A bidirectional punching device for automotive door frame glass guide rails includes a punching base 1. A support block 6 is provided on one side of the top of the punching base 1. A positioning component for positioning the sunroof guide rail is movably installed inside the support block 6. Screws 5 are rotatably installed at both ends of the side wall of the support block 6. A movable seat 4 is threaded on the outside of the screws 5. A connecting block 16 is provided on the side wall of the movable seat 4. A punching blade 14 for punching the sunroof guide rail is provided on the side wall of the connecting block 16. Cleaning brushes 13 for cleaning debris are provided on both sides of the punching blade 14. Multiple drainage holes for debris to fall off are opened on the top of the punching base 1. A drive motor 2 is provided on the top of the other side of the punching base 1. The output shaft of the drive motor 2 is connected to one of the screws 5 through a coupling.

[0025] By using the cleaning brush 13, various debris generated during the operation can be effectively collected through the drain holes and guided into the internal space of the collection drawer 7, ensuring that excessive debris does not accumulate on the top of the punching seat 1. Excessive debris accumulation may put unnecessary pressure on the surface of the punching seat 1, affecting its normal operation. Furthermore, debris accumulation may interfere with subsequent punching operations, leading to decreased punching accuracy and affecting product quality. Therefore, using the cleaning brush 13 to keep the working area clean helps maintain the cleanliness of the punching seat 1, ensuring smooth punching operations.

[0026] like Figure 3 As shown, both screws 5 are equipped with synchronous pulleys 9 on their exteriors, and the two synchronous pulleys 9 are connected by a synchronous belt 3.

[0027] The drive motor 2 drives one of the screws 5 to rotate, and at the same time works with the timing belt 3 and timing pulley 9 to drive the other screw 5 to rotate. The two screws 5 can drive the two moving seats 4 to move. The punching blade 14 on the side wall of the moving seat 4 can perform bidirectional punching work on the sunroof guide rail.

[0028] like Figure 2 As shown, the top of the punching seat 1 is provided with a placement frame 8 for placing the sunroof guide rail.

[0029] By placing the sunroof guide rail inside the placement frame 8, any unnecessary movement of the sunroof guide rail during punching operations can be effectively prevented, thus ensuring the accuracy and stability of the entire punching process.

[0030] like Figure 4 As shown, the positioning assembly includes a positioning bolt 10 threaded inside the support block 6, a top block 11 at one end of the positioning bolt 10, and an anti-slip pad 12 on the side wall of the top block 11 to increase friction with the sunroof guide rail.

[0031] By cleverly using the rotating positioning bolt 10, the top block 11 can be effectively driven to apply pressure to the sunroof guide rail. At the same time, the anti-slip pad 12 equipped on the side wall of the top block 11 will also make close contact with the sunroof guide rail and generate a squeezing effect. Through the coordinated work of the top block 11 and the anti-slip pad 12, the stability of the sunroof guide rail during the punching operation is greatly enhanced, ensuring the accuracy and safety of the entire process.

[0032] like Figure 5 and Figure 6 As shown, a limit block 15 is provided on the top of the movable seat 4, and a limit groove is provided on the top of the punching seat 1 for the limit block 15 to move.

[0033] By sliding the limit block 15 within the limit groove, the position of the movable seat 4 can be effectively prevented from shifting during movement, ensuring better stability of the entire movable seat 4 during operation.

[0034] like Figure 6 As shown, the inside of the punching seat 1 is symmetrically provided with guide blocks 17 for guiding the movement of debris, and the inside of the punching seat 1 is movably provided with a collection tray 7 for collecting debris.

[0035] Guide block 17 can accurately guide the fallen debris into the collection drawer 7, making it easier to centrally process and clean up the debris later.

[0036] Working principle: When punching the sunroof guide rail, first place the sunroof guide rail inside the placement frame 8 to prevent it from moving during punching. Then, rotate the positioning bolt 10 to drive the top block 11 to press the sunroof guide rail. At the same time, the anti-slip pad 12 on the side wall of the top block 11 also presses against the sunroof guide rail. The top block 11 and the anti-slip pad 12 make the sunroof guide rail more stable during punching. Then, the drive motor 2 drives one of the screws 5 to rotate, which works in conjunction with the timing belt 3 and timing pulley 9 to drive the other screw 5. One screw 5 rotates, and two screws 5 can drive two moving seats 4 to move. The punching blade 14 on the side wall of the moving seat 4 can perform bidirectional punching work on the sunroof guide rail. At the same time, the cleaning brush 13 can collect the debris generated during the operation through the drain hole into the inside of the collection drawer 7 to prevent the top of the punching seat 1 from pushing a large amount of debris, which would affect the subsequent punching work. The cleaning brush 13 and the punching blade 14 are both connected to the moving seat 4 by nuts and can be replaced and cleaned after a period of use.
