[0039] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0040] This application discloses an airbag inflator. (Refer to...)

[0042] In this application, the airbag workpiece is inserted horizontally into the lower punch mechanism 3, and the upper punch mechanism 4 is driven by the stamping drive mechanism 2 to insert into the lower punch mechanism 3 to stamp and cut the airbag workpiece. The workpiece end stamping assembly 42 and the lower punch mechanism 3 press together to stamp and cut the end of the airbag workpiece, and the punching assembly 43 and the lower punch mechanism 3 press together to cut and punch holes in the airbag workpiece, forming in one step. Furthermore, the workpiece end stamping assembly 42 is detachably connected to the connecting top post 41, and the punching assembly 43 is detachably connected to the workpiece end stamping assembly 42, so that the workpiece end stamping assembly 42 and the punching assembly 43 can be flexibly replaced as needed, thereby improving production efficiency and adapting to the stamping requirements of different airbag workpieces.

[0043] This application realizes the automated stamping process of airbag workpieces. The driving action of the stamping drive mechanism 2 enables the upper punch mechanism 4 to automatically insert or withdraw the lower punch mechanism 3, ensuring the accuracy and consistency of the stamping process, effectively avoiding dimensional errors and air leakage problems that may occur in manual operation, and improving the quality and production efficiency of airbag products.

[0044] Furthermore, such as Figure 2 As shown, the connecting top post 41 includes a top post body 411 that is detachably connected to the output end of the stamping drive mechanism 2, and an insertion protrusion 412 located at the bottom of the top post body 411 and engaged with the workpiece end stamping assembly 42; the side wall of the insertion protrusion 412 is provided with a protrusion insertion groove 413 for the workpiece end stamping assembly 42 to be inserted.

[0045] The top column body 411 of this application is detachably connected to the output end of the stamping drive mechanism 2, which facilitates quick replacement and maintenance. The insertion protrusion 412 at the bottom of the top column body 411 and the workpiece end stamping assembly 42 are connected by insertion to achieve precise positioning and stable connection. The protrusion insertion groove 413 on the side wall of the insertion protrusion 412 further ensures the smooth insertion and fixation of the workpiece end stamping assembly 42 in the horizontal direction, thereby improving the operation convenience and stamping accuracy of the entire stamping device, while reducing production errors and equipment failures caused by unstable connection.

[0046] Furthermore, such as Figure 2 As shown, the workpiece end stamping assembly 42 includes an upper punch stamping part 421, an upper punch retainer 422 disposed on the upper end of the upper punch stamping part 421 and detachably connected to the insertion protrusion 412, and an upper punch connector 423 passing through the upper punch retainer 422 and connected to the upper punch stamping part 421.

[0047] The upper punch stamping part 421 of this application is directly used for stamping, ensuring the direct transmission of stamping force; the upper punch retainer 422 is located at the upper end of the upper punch stamping part 421 and cooperates with the plug-in protrusion 412 through a detachable connection, which facilitates quick replacement and adjustment of the workpiece end stamping assembly 42 to adapt to the stamping requirements of different workpieces; the upper punch connector 423 passes through the upper punch retainer 422 and connects to the upper punch stamping part 421, ensuring the stability and durability of the workpiece end stamping assembly 42; this application improves stamping efficiency, reduces maintenance costs, and enhances the adaptability and reliability of the equipment.

[0048] The upper punch connector 423 is preferably a bolt.

[0049] Specifically, such as Figure 2 and Figure 3As shown, the upper punch snap-fit ​​seat 422 includes a snap-fit ​​seat body 4221, a snap-fit ​​protrusion 4222 disposed at the upper end of the snap-fit ​​seat body 4221 and used for horizontal insertion into the protrusion insertion groove 413, and a punching limiting protrusion 4223 disposed on the side wall of the snap-fit ​​seat body 4221 and used for insertion of the end of the punching assembly 43.

[0050] The snap-fit ​​flange 4222 and the snap-fit ​​base body 4221 are arranged to form a sliding insertion groove 4224 for the insertion of the insertion protrusion 412 in the horizontal direction. The punching limiting flange 4223 and the snap-fit ​​base body 4221 are arranged to form a punching limiting groove 4225 for the insertion of the end of the punching assembly 43. The snap-fit ​​base body 4221 is provided with a connecting hole 4226 that communicates with the sliding insertion groove 4224 and is used for the upper punch connector 423 to pass through.

[0051] The snap-fit ​​flange 4222 is inserted horizontally into the protrusion insertion groove 413, ensuring a sliding fit with the insertion protrusion 412 and improving the flexibility and adaptability of the workpiece end stamping assembly 42. The punching limiting flange 4223 provides an accurate horizontal insertion position for the end of the punching assembly 43, and the punching limiting groove 4225 restricts the vertical movement of the punching assembly 43, ensuring the accuracy of downward punching. The connection hole 4226 allows the upper punch connector 423 to pass through, providing a fixed connection point for the workpiece end stamping assembly 42, ensuring the stability and durability of the overall structure. This application not only improves the operational convenience and production efficiency of the stamping device, but also improves the accuracy and consistency of stamping and punching through precise positioning and limiting mechanisms.

[0052] More specifically, such as Figure 2 As shown, the upper punch stamping part 421 includes an upper punch body 4211, a limiting flange 4212 located at the lower end of the upper punch body 4211, and inclined stamping sidewalls 4213 located on both sides of the limiting flange 4212; an arc-shaped cutting groove 4214 is provided between the inclined stamping sidewall 4213 and the upper end face of the upper punch body 4211, and the punching assembly 43 is inserted into the arc-shaped cutting groove 4214 and maintains a gap with the sidewall of the arc-shaped cutting groove 4214.

[0053] The limiting flange 4212 at the lower end of the upper punch body 4211 ensures stability and positioning accuracy during the stamping process. The inclined stamping sidewalls 4213 on both sides cooperate with the arc-shaped cutting groove 4214 between the upper end face of the upper punch body 4211 to achieve arc-shaped cutting of the end of the airbag workpiece, which helps to reduce stress concentration in the airbag workpiece and improve cutting quality. The punching assembly 43 is inserted into the arc-shaped cutting groove 4214 and maintains a gap with the sidewall, ensuring flexibility and accuracy during the punching process. At the same time, the existence of the gap also helps to reduce friction and wear and extend the service life of the equipment. This application realizes efficient and accurate stamping and cutting functions, improves the working efficiency and product quality of the stamping device, and reduces maintenance costs and operating difficulty.

[0054] Furthermore, the two inclined stamping sidewalls 4213 on both sides of the limiting protrusion 4212 can simultaneously stamp and cut the ends of two airbag workpieces, which improves the working efficiency of the stamping device, reduces the processing time of a single airbag workpiece, and maintains the consistency and accuracy of the cutting, thereby improving production efficiency and reducing production costs.

[0055] In addition, such as Figure 2 As shown, the punching assembly 43 includes a punch 431, a punch fixing flange 432 disposed at the upper end of the punch 431 and used for insertion into the punching limiting groove 4225, and an inclined cutting end face 433 disposed at the lower end of the punch 431.

[0056] The punch fixing protrusion 432 at the upper end of the punch 431 is inserted into the punching limiting groove 4225 in the horizontal direction. The punching limiting protrusion 4223 and the side wall of the punching limiting groove 4225 press against the punch fixing protrusion 432 in the vertical direction, ensuring the stability and precise positioning of the punch 431 during the downward punching process. The inclined cutting end face 433 at the lower end of the punch 431 allows for inclined cutting of the airbag workpiece, which helps to reduce tearing of the airbag workpiece, improve the quality of the cutting edge, and also reduce the punching resistance required during the cutting process, thereby improving the overall punching efficiency and the processing quality of the airbag workpiece.

[0057] The inclined cutting end face 433 is preferably an inverted "V" shaped structure; the inverted "V" shaped cutting end face helps to form a clear cut during the cutting process, reducing tearing and burrs on the airbag workpiece, thereby improving the cutting quality; it helps to concentrate the cutting force, making the cutting more accurate and efficient; it may also reduce the lateral pressure on the airbag workpiece during cutting, reducing the risk of damage to the airbag workpiece.

[0058] And, as Figures 2 to 4As shown, the lower punch mechanism 3 includes a waste discharge assembly 31 connected to the base 1, a lower punch assembly 32 disposed on the waste discharge assembly 31 and used for insertion and cooperation with the upper punch mechanism 4, and a top-pressing cutting flange 33 inserted in the lower punch assembly 32; the top-pressing cutting flange 33 is used to press and cooperate with the workpiece end stamping assembly 42 and the punching assembly 43 respectively to press and cut the airbag workpiece;

[0059] The lower punch assembly 32 is provided with an end punching through hole 321 arranged vertically for inserting the workpiece end punching assembly 42, a punching through hole 322 arranged vertically for inserting the punching assembly 43, and a workpiece insertion hole 323 arranged horizontally and communicating with the end punching through hole 321 and the punching through hole 322 respectively.

[0060] The waste discharge assembly 31 of this application is connected to the base 1 for the smooth discharge of stamping waste, ensuring a clean working environment and a smooth production process. The end stamping through hole 321 and punching through hole 322 on the lower punch assembly 32 provide a precise insertion position for the workpiece end stamping assembly 42 and punching assembly 43, ensuring the accuracy of stamping and punching. The workpiece insertion hole 323 is set in the horizontal direction and connects the end stamping through hole 321 and punching through hole 322, facilitating the rapid positioning and insertion of the airbag workpiece and improving production efficiency. The top-pressing cutting flange 33 cooperates with the top-pressing of the workpiece end stamping assembly 42 and punching assembly 43 to achieve precise cutting of the airbag workpiece and ensure cutting quality. This application improves the ease of operation, production efficiency and product quality of the stamping device, while reducing the difficulty of operation and maintenance costs.

[0061] This application also discloses that the limiting flange 4212 has two workpiece insertion holes 323 on both sides for synchronous stamping and cutting of the ends of the two airbag workpieces. The two side walls of the limiting flange 4212 are respectively used to press and cooperate with the ends of the two airbag workpieces, providing stable positioning for the airbag workpieces.

[0062] Furthermore, such as Figure 3 As shown, the cross-sectional area of ​​the through holes at the lower opening ends of the end punched through holes 321 and 322 gradually increases in the direction away from the punching drive mechanism 2.

[0063] The cross-sectional area of ​​the lower opening end of the end punching through hole 321 and punching through hole 322 of this application gradually increases in the direction away from the punching drive mechanism 2, which helps to provide a smoother waste discharge path during the punching process, thereby improving the punching efficiency.

[0064] Furthermore, such as Figure 2 and Figure 3As shown, the waste discharge assembly 31 includes a waste discharge body 311 and a guide slope 312 provided on the waste discharge body 311. The guide slope 312 and the waste discharge body 311 surround each other to form a guide chute 313 for discharging workpiece waste. The guide chute 313 is connected to the bottom of the end punching through hole 321 and the punching through hole 322, respectively.

[0065] This application combines the waste discharge body 311 and the guide slope 312 to form a guide chute 313, which not only provides an effective waste discharge path, but also enhances the guiding and sliding efficiency of waste through the design of the guide slope 312. The connectivity between the guide chute 313 and the bottom of the end punching through hole 321 and punching through hole 322 ensures that the waste generated during the stamping process can be smoothly discharged from the bottom of the end punching through hole 321 and punching through hole 322, avoiding the problems of waste accumulation and blockage, thereby keeping the stamping device clean, reducing maintenance requirements, and improving the continuity and efficiency of the entire stamping process.

[0066] Specifically, such as Figure 2 As shown, the stamping drive mechanism 2 includes a power drive assembly 21 mounted on the base 1, and a manual air valve 22 connected to the power drive assembly 21.

[0067] The power drive assembly 21 of this application is responsible for providing the power required for stamping, and the manual air valve 22 is used by the operator to manually control the opening and closing of the air valve as needed, thereby achieving precise adjustment of the stamping pressure and speed; this not only improves the controllability of the stamping process, but also increases the flexibility and safety of operation, so that the stamping operation can be finely adjusted according to specific needs to adapt to different production conditions and airbag workpiece characteristics, thereby improving production efficiency and product quality.

[0068] The power drive component 21 is preferably a cylinder.

[0069] The implementation principle of an airbag compression device according to an embodiment of this application is as follows:

[0070] The airbag workpiece is inserted horizontally into the lower punch mechanism 3. The upper punch mechanism 4 is driven by the stamping drive mechanism 2 to insert into the lower punch mechanism 3 for stamping and cutting the airbag workpiece. The workpiece end stamping assembly 42 and the lower punch mechanism 3 press together to stamp and cut the end of the airbag workpiece. The punching assembly 43 and the lower punch mechanism 3 press together to cut and punch holes in the airbag workpiece, forming it in one step. The workpiece end stamping assembly 42 is detachably connected to the connecting top post 41, and the punching assembly 43 is detachably connected to the workpiece end stamping assembly 42. This allows the workpiece end stamping assembly 42 and the punching assembly 43 to be flexibly replaced as needed, thereby improving production efficiency and adapting to the stamping requirements of different airbag workpieces. This application realizes an automated stamping process for airbag workpieces. The driving action of the stamping drive mechanism 2 enables the upper punch mechanism 4 to automatically insert or withdraw from the lower punch mechanism 3, ensuring the accuracy and consistency of the stamping process, effectively avoiding dimensional errors and air leakage problems that may occur in manual operation, and improving the quality and production efficiency of airbag products.

[0071] The punch fixing protrusion 432 at the upper end of the punch 431 is inserted into the punching limiting groove 4225 in the horizontal direction. The punching limiting protrusion 4223 and the side wall of the punching limiting groove 4225 press against the punch fixing protrusion 432 in the vertical direction, ensuring the stability and precise positioning of the punch 431 during the downward punching process. The inclined cutting end face 433 at the lower end of the punch 431 allows for inclined cutting of the airbag workpiece, which helps to reduce tearing of the airbag workpiece, improve the quality of the cutting edge, and also reduce the punching resistance required during the cutting process, thereby improving the overall punching efficiency and the processing quality of the airbag workpiece.

[0072] The combination of the waste discharge body 311 and the guide slope 312 forms the guide chute 313, which not only provides an effective waste discharge path, but also enhances the guiding and sliding efficiency of waste through the design of the guide slope 312. The connectivity between the guide chute 313 and the bottom of the end punching through hole 321 and punching through hole 322 ensures that the waste generated during the stamping process can be smoothly discharged from the bottom of the end punching through hole 321 and punching through hole 322, avoiding the problems of waste accumulation and blockage, thereby keeping the stamping device clean, reducing maintenance requirements, and improving the continuity and efficiency of the entire stamping process.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
