Description

Technical Field

[0001] This utility model relates to the field of car window guide rail processing technology, specifically a stamping device for processing car window guide rails that can prevent loosening. Background Technology

[0002] Window rails are grooves or ridges made of metal or other materials that support, fix, and guide moving devices or equipment and reduce their friction. Window rails are manufactured using molds.

[0003] For example, the window guide rail processing mold disclosed in announcement number "CN220611840U" has the following characteristics: In actual operation, the sheet material to be stamped is placed on the top of the lower mold, and then the hydraulic cylinder is activated to control the upper mold to perform the stamping operation. However, the sheet material is not fixed during this process. This means that if the sheet material is accidentally touched before the upper mold contacts and presses it, it is very likely to become skewed and loose. Therefore, we propose a stamping device for processing window guide rails that can prevent loosening. Utility Model Content

[0004] The purpose of this invention is to provide a stamping device for processing car window guide rails that can prevent loosening, 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 stamping device for processing a car window guide rail that can prevent loosening, comprising a base, a stamping mechanism provided on the top of the base, and a driven component for temporarily fixing the sheet metal on the top of the base. The driven component includes a fixing frame, which is fixed to the top of the base. The top of the fixing frame is penetrated by a round tube and slidably connected to the round tube. A return spring is fixed to the bottom of the round tube, and the end of the return spring away from the round tube is fixed to the inner wall of the fixing frame.

[0006] Preferably, a suction cup is fixed to the top of the circular tube, and a circular hole is opened at the top of the circular tube. The circular tube communicates with the suction cup through the circular hole at the top. A movable disk is connected to a piston on the inner wall of the circular tube. The interior of the circular tube at the bottom of the movable disk is the lower cavity, and the interior of the circular tube at the top of the movable disk is the upper cavity. A connecting rod is fixed to the bottom of the movable disk. The connecting rod passes through the bottom of the circular tube and is connected to the piston of the circular tube. The bottom of the connecting rod is fixed to the inner wall of the fixing frame. A connecting frame is fixed to the top of the base. A horizontal tube is fixed to the inner wall of the connecting frame. A connecting disk is connected to a piston inside the horizontal tube. A push rod is fixed to the front of the connecting disk. The push rod passes through the horizontal tube and is connected to the piston of the horizontal tube. The push rod passes through the connecting frame and is slidably connected to the connecting frame. A contact plate is fixed to the end of the push rod away from the connecting disk. The interior of the horizontal tube at the front of the connecting disk is the front cavity, and the interior of the horizontal tube at the back of the connecting disk is the rear cavity. The front cavity communicates with the upper cavity through an air pipe one, and the rear cavity communicates with the lower cavity through an air pipe two. The cavity is connected. When the sheet material is placed on the suction cup, pushing the sheet material pushes the contact plate, causing the contact plate to move towards the side closer to the connecting frame with the push rod. The push rod moves the connecting plate inside the horizontal tube. At this time, the front cavity draws gas from the upper cavity through the air pipe, causing the suction cup to adhere to the sheet material, effectively preventing the sheet material from tilting and loosening when touched. When the stamping mechanism stamps the sheet material, pressing the sheet material downwards, the sheet material moves downwards along with the suction cup and the round tube. At this time, the moving plate moves upwards inside the round tube to supply air to the suction cup, causing the suction cup to no longer adhere to and fix the sheet material, thus releasing the sheet material and avoiding affecting the normal processing operation of the sheet material. After the stamping is completed, the stamping mechanism resets. After the stamped guide rail is removed, the suction cup is no longer touched. Under the action of the return spring, the round tube moves upwards. At this time, the moving plate moves downwards inside the round tube, and the lower cavity can supply gas to the rear cavity through the air pipe, pushing the connecting plate, push rod, and contact plate to reset, completing the device reset.

[0007] Preferably, a fixing block is fixed to the top of the base, the fixing block is penetrated by a support rod and slidably connected to the support rod, a connecting spring is fixed to the inner wall of the fixing block, and the end of the connecting spring away from the fixing block is fixed to the support rod. The support rod can work with the round tube and suction cup to lift the sheet metal and prevent the sheet metal from tilting during stamping.

[0008] Preferably, the stamping mechanism includes a lower die, which is fixed to the top of the base. A support frame is fixed to the top of the base, and a hydraulic cylinder is fixed to the bottom of the support frame. The output shaft of the hydraulic cylinder is fixed to the upper die, and a guide rod is fixed to the top of the upper die. The guide rod passes through the support frame and is slidably connected to the support frame. The upper die is driven to move downward by the hydraulic cylinder, and the lower die can be used to perform stamping operations on the sheet metal. The guide rod allows the upper die to move more stably.

[0009] Preferably, the top of the fixing frame is provided with a circular groove, which is adapted to the suction cup. When the plate is pressed and moved downward, the suction cup can be embedded in the circular groove to avoid affecting the normal stamping.

[0010] Compared with the prior art, this utility model provides a stamping device for processing car window guide rails that can prevent loosening, which has the following beneficial effects:

[0011] 1. This anti-loosening stamping device for processing car window guide rails works by pushing a sheet metal plate onto a suction cup. The plate pushes a contact plate, causing it to move towards the connecting frame along with a push rod. The push rod moves the connecting plate within the horizontal tube. Simultaneously, the front chamber draws gas from the upper chamber through an air pipe, causing the suction cup to hold the sheet metal in place. This effectively prevents the sheet metal from tilting or loosening upon contact. During the stamping operation, as the plate metal is pressed downwards, it moves downwards along with the suction cup and the round tube. At this time, the moving plate moves upwards within the round tube, supplying air to the suction cup, causing it to release the sheet metal and prevent interference with normal processing.

[0012] 2. The anti-loosening stamping device for processing car window guide rails, after the stamping is completed, the stamping mechanism resets. After the stamped guide rail is removed, the suction cup is no longer abutted. Under the action of the reset spring, the round tube moves upward. At this time, the moving plate moves downward in the round tube. The lower chamber can then supply gas to the rear chamber through the air pipe, pushing the connecting plate to reset with the push rod and the abutment plate, thus completing the device reset.

[0021] like Figures 1-7 As shown, this utility model provides a technical solution: a stamping device for processing a car window guide rail that can prevent loosening, including a base 1, a stamping mechanism 2 provided on the top of the base 1, and a driven component 3 for temporarily fixing the plate material on the top of the base 1.

[0022] The driven component 3 includes a fixed frame 31, which is fixed to the top of the base 1. The top of the fixed frame 31 is penetrated by a circular tube 32 and slidably connected to the circular tube 32. A return spring 33 is fixed to the bottom of the circular tube 32, and the end of the return spring 33 away from the circular tube 32 is fixed to the inner wall of the fixed frame 31. A suction cup 34 is fixed to the top of the circular tube 32, and a circular hole is opened in the top of the circular tube 32, through which the circular tube 32 communicates with the suction cup 34. A movable disk 35 is piston-connected to the inner wall of the circular tube 32. The lower cavity 36 is located inside the circular tube 32 at the bottom of the movable disk 35, and the upper cavity 37 is located inside the circular tube 32 at the top of the movable disk 35. A connecting rod 38 is fixed to the bottom of the movable disk 35. Connecting rod 38 passes through the bottom of round tube 32 and is connected to the piston of round tube 32. The bottom of connecting rod 38 is fixed to the inner wall of fixed frame 31. A connecting frame 39 is fixed to the top of base 1. A horizontal tube 310 is fixed to the inner wall of connecting frame 39. A connecting plate 311 is connected to the piston inside the horizontal tube 310. A push rod 312 is fixed to the front of connecting plate 311. Push rod 312 passes through horizontal tube 310 and is connected to the piston of horizontal tube 310. Push rod 312 passes through connecting frame 39 and is slidably connected to connecting frame 39. An abutment plate 313 is fixed to the end of push rod 312 away from connecting plate 311. The front cavity 314 is located inside the horizontal tube 310 on the front of connecting plate 311. The back cavity 314 is located inside the horizontal tube 310 on the back of connecting plate 311. The interior of tube 310 is a rear cavity 315. The front cavity 314 is connected to the upper cavity 37 via air pipe 316, and the rear cavity 315 is connected to the lower cavity 36 via air pipe 317. When the plate is placed on the suction cup 34, pushing the plate pushes the contact plate 313, causing the contact plate 313 to move with the push rod 312 towards the side closer to the connecting frame 39. The push rod 312 moves the connecting plate 311 within the horizontal tube 310. At this time, the front cavity 314 draws gas from the upper cavity 37 via air pipe 316, causing the suction cup 34 to hold the plate in place, effectively preventing the plate from tilting and loosening when touched. The stamping mechanism 2 then performs a stamping operation on the plate, pressing it downwards. During operation, the plate moves downward along with the suction cup 34 and the round tube 32. At this time, the moving disk 35 moves upward inside the round tube 32 to supply air to the suction cup 34, so that the suction cup 34 no longer adheres to and fixes the plate, thereby releasing the plate and avoiding affecting the normal processing operation of the plate. After the stamping is completed, the stamping mechanism 2 resets and the stamped guide rail is removed. The suction cup 34 is no longer resisted. Under the action of the reset spring 33, the round tube 32 moves upward. At this time, the moving disk 35 moves downward inside the round tube 32, and the lower cavity 36 can supply gas to the rear cavity 315 through the second air pipe 317, pushing the connecting disk 311 to reset along with the push rod 312 and the contact plate 313, thus completing the device reset.

[0023] A fixing block 4 is fixed to the top of the base 1. The fixing block 4 is penetrated by the support rod 5 and is slidably connected to the support rod 5. A connecting spring 6 is fixed on the inner wall of the fixing block 4. The end of the connecting spring 6 away from the fixing block 4 is fixed to the support rod 5. The support rod 5 can work with the round tube 32 and the suction cup 34 to lift the plate and prevent the plate from tilting during stamping.

[0024] The stamping mechanism 2 includes a lower die 21, which is fixed to the top of the base 1. A support frame 22 is fixed to the top of the base 1, and a hydraulic cylinder 23 is fixed to the bottom of the support frame 22. The output shaft of the hydraulic cylinder 23 is fixed to the upper die 24, and a guide rod 25 is fixed to the top of the upper die 24. The guide rod 25 passes through the support frame 22 and is slidably connected to the support frame 22. The upper die 24 is driven to move downward by the hydraulic cylinder 23, and the lower die 21 can be used to stamp the sheet metal. The guide rod 25 makes the upper die 24 move more stably. A circular groove 7 is opened on the top of the fixed frame 31. The circular groove 7 is adapted to the suction cup 34. When the sheet metal is pressed and moved downward, the suction cup 34 can be embedded in the circular groove 7 to avoid affecting the normal stamping.

[0025] Based on the above implementation method, the sheet metal to be stamped is placed on the top of the lower die 21. At this time, the sheet metal is on the suction cup 34 and the support rod 5. After the position of the sheet metal is adjusted, the sheet metal is pushed to move towards the side closer to the contact plate 313. This causes the sheet metal to push the contact plate 313, along with the push rod 312, towards the side closer to the connecting frame 39. The push rod 312 moves the connecting plate 311 within the horizontal tube 310. At this time, the front cavity 314 draws gas from the upper cavity 37 through the air pipe 316, causing the suction cup 34 to hold the sheet metal in place. This effectively prevents the sheet metal from tilting and loosening when it is touched. When the stamping mechanism 2 performs the stamping operation on the sheet metal and pushes the sheet metal downwards... The sheet metal, along with the suction cup 34 and the round tube 32, moves downwards. At this time, the moving plate 35 moves upwards inside the round tube 32 to supply air to the suction cup 34, so that the suction cup 34 no longer adheres to and fixes the sheet metal, thereby releasing the sheet metal and avoiding affecting the normal processing operation of the sheet metal. After the stamping is completed, the stamping mechanism 2 resets and the stamped guide rail is removed. The suction cup 34 is no longer resisted. Under the action of the reset spring 33, the round tube 32 moves upwards. At this time, the moving plate 35 moves downwards inside the round tube 32, and the lower cavity 36 can supply gas to the rear cavity 315 through the second air pipe 317, pushing the connecting plate 311 to reset along with the push rod 312 and the contact plate 313, thus completing the device reset.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
