Description

Technical Field

[0001] This application relates to the field of automotive parts processing equipment technology, and in particular to a side-wrapping mechanism for an airbag mounting plate. Background Technology

[0002] In automotive safety systems, airbags, as a core component of passive safety systems, directly impact the safety of occupants. When a collision occurs, airbags must deploy precisely and instantly to effectively reduce the impact on occupants through cushioning. The airbag mounting plate, as a crucial component for supporting and securing the airbag, determines the stability and assembly precision of the airbag installation through the quality of its side edge processing. If the bending angle of the side edge deviates or the dimensions do not meet design standards, the airbag may become loose or shifted after installation, preventing it from deploying properly in a collision and significantly weakening its safety protection effect.

[0003] Currently, the automotive parts manufacturing industry commonly uses a combination of punch presses and molds to achieve precise forming of the side edges of airbag mounting plates. This process involves using a mold to precisely position the material sheet, and then using a punch press to apply pressure to plastically deform the side edges of the sheet, thereby obtaining a standard workpiece that meets design requirements.

[0004] Reference Figure 1 A standard workpiece for common airbag mounting plates is integrally formed from a mounting base plate 01, a connecting part 02, and an edge-wrapping part 03. The mounting base plate 01 has openings 011 of various specifications distributed on it to avoid other parts and to install connecting bolts. The connecting part 02 is inclinedly set on one side of the mounting base plate 01 and connected to the side wall of the base plate. The edge-wrapping part 03 is located on the other side of the mounting base plate 01, and its lower end, which has been bent, points downwards from the mounting base plate 01.

[0005] However, due to the complex shape and structure of the airbag mounting plate, existing single stamping equipment exhibits significant shortcomings in side edge processing. Because it cannot precisely bend complex shapes in one operation, multiple clamping and positioning operations are often required. This not only significantly extends the processing cycle and reduces production efficiency, but also accumulates positioning errors due to repeated clamping, making it difficult to meet the bending accuracy of the side edge. This directly affects product quality and the subsequent airbag assembly compatibility, making it difficult to meet the automotive industry's demands for high-precision and high-efficiency parts production. Utility Model Content

[0006] To improve the efficiency of processing and mounting plate side edge wrapping, this application provides a side edge wrapping mechanism for airbag mounting plates.

[0007] The side-wrapping mechanism for an airbag mounting plate provided in this application adopts the following technical solution:

[0008] A side-sealing mechanism for an airbag mounting plate includes a lower template and an upper template. The lower template has a support base for placing the workpiece to be stamped. A first groove is formed on one side of the lower template near the support base, extending perpendicular to the length of the support base. A movable plate is slidably disposed within the first groove. An inner abutment is provided at one end of the movable plate near the support base. A second groove is formed on the top of the movable plate parallel to the length of the first groove, and an inner abutment is slidably disposed within the second groove. The outer pressure block is inserted and connected. A driving block is provided at one end of the moving plate away from the support base. The driving block and the outer pressure block are provided with inclined side panels on opposite sides. The tops of the two inclined side panels extend in opposite directions. A lower pressure seat is provided on the upper template between the driving block and the outer pressure block. Both sides of the lower pressure seat are provided with inclined push panels that cooperate with the inclined side panels. When the upper template is pressed down, the inclined push panels on both sides of the lower pressure seat push the inner abutment block and the outer pressure block to slide relative to each other through the inclined surface until the inner abutment block and the outer pressure block clamp the edge part to form a shape.

[0009] By adopting the above technical solution, when stamping the side edge of the airbag mounting plate, the workpiece to be stamped is placed on the support base, and the upper template is driven to press down. During this process, the inclined push panels on both sides of the lower press base push the drive block and the outer pressure block to slide in opposite directions through the inclined surfaces. The sliding of the drive block drives the inner abutment block to slide in the same direction, thereby realizing the relative sliding between the inner abutment block and the outer pressure block until the inner abutment block and the outer pressure block clamp and form the edge. This is because the inclined surfaces of the inclined side panel and the inclined push panel cooperate to convert the vertical downward force of the upper template into the horizontal relative motion force of the inner abutment block and the outer pressure block, thereby completing the clamping and forming of the edge in one go, eliminating the need for multiple clamping and positioning, improving the work efficiency of processing the side edge of the mounting plate, improving the bending accuracy of the side edge, and enhancing the product quality and subsequent airbag assembly compatibility.

[0010] Optionally, a reset clamp is provided on each of the two side walls of the lower pressure seat adjacent to the outer pressure block. The reset clamp includes a support part and a plug-in part. One end of the support part is connected to the side wall of the lower pressure seat, and the plug-in part is vertically connected to the other end of the support part. The two plug-in parts are arranged opposite to each other. A plug-in guide groove is provided on the side wall of the outer pressure block parallel to the inclined side panel. The top of the plug-in guide groove extends to the top wall of the outer pressure block. The plug-in part is inserted from the top opening of the plug-in guide groove and slides with the plug-in guide groove.

[0011] By adopting the above technical solution, after the side edge stamping of the airbag mounting plate is completed, the upper template rises and drives the lower pressure seat to rise. The insertion part of the reset clamp slides in the insertion guide groove and pushes against its upper inner side wall, so that the outer pressure block slides synchronously away from the inner block and automatically resets to the initial position, which facilitates the next edge-sealing operation. There is no need to manually adjust the position of the outer pressure block, which improves the working efficiency and automation of the side edge-sealing mechanism and reduces the error and time cost caused by manual intervention.

[0012] Optionally, the top surface of the mobile plate is provided with multiple parallel supporting slide plates, which are parallel to the length direction of the second slide groove, and the bottom of the outer pressure block is slidably mounted on the multiple supporting slide plates.

[0013] By adopting the above technical solution, the supporting slide plate can support the sliding outer pressure block, reduce the friction between the outer pressure block and the moving plate, and make the outer pressure block slide more smoothly in the second slide groove, which helps to improve the operational stability and working efficiency of the airbag mounting plate side edge wrapping mechanism.

[0014] Optionally, a calibration rod is provided on the side wall of the outer pressure block, and a proximity switch for docking the calibration rod is provided on the lower template.

[0015] By adopting the above technical solution, it is convenient to calibrate the precise position of the outer pressure block before each stamping process, ensuring that the outer pressure block can accurately cooperate with the inner abutment block during the stamping process, thereby improving the processing accuracy and forming quality of the side edge of the airbag mounting plate.

[0016] Optionally, a guide groove is provided in the first slide groove, and a slider is slidably disposed in the guide groove. The slider is connected to the moving plate. An elastic reset member is provided in the guide groove, and the two ends of the elastic reset member are respectively connected to the inner end wall of the guide groove and the side wall of the slider.

[0017] By adopting the above technical solution, the sliding of the slider in the guide groove provides a stable guide for the movement of the moving plate, which helps to improve the accuracy and quality of the edge clamping and forming. After the edge stamping of the airbag mounting plate is completed, the upper template rises, driving the lower pressure seat to rise. At this time, the elastic reset component can assist the moving plate in sliding in the first slide groove, which facilitates the reset of the device and its reoperation, and helps to improve the working efficiency of processing the edge of the mounting plate.

[0018] Optionally, a positioning rod is vertically provided at the bottom of the upper template, and a positioning hole is provided on the support base to be inserted into the positioning rod. When the upper template is pressed down, the bottom end of the positioning rod passes through the opening on the mounting base plate and is inserted into the positioning hole.

[0019] By adopting the above technical solution, the positioning rod slides precisely through the opening on the mounting plate during the pressing of the upper template and engages with the positioning groove on the top of the support base, thereby limiting the workpiece in the lateral direction, reducing the risk of workpiece displacement during stamping, improving the processing accuracy of the side edge of the airbag mounting plate, and thus improving product quality and the subsequent assembly compatibility of the airbag.

[0020] Optionally, a pressure plate is provided between the lower platen and the upper platen, and a vertically arranged elastic telescopic member is connected between the pressure platen and the upper platen. The bottom end of the positioning rod slides through the pressure platen and slides in cooperation with it.

[0021] By adopting the above technical solution, during the descent of the upper template, the pressure template first contacts the mounting base and presses it against the support seat, so that the workpiece is further longitudinally limited on the basis of the lateral limit of the positioning rod, which improves the stability of the side edge of the mounting plate. At the same time, the elastic telescopic component provides a buffer for the pressure template, reducing the possibility of workpiece damage caused by hard contact during side edge stamping.

[0022] Optionally, the bottom of the pressing template is provided with multiple mating grooves, and the top of the support base is provided with multiple mating protrusions, the mating protrusions and the mating grooves are corresponding one to one and are inserted into each other.

[0023] By adopting the above technical solution and utilizing the interlocking fit between the mating protrusion and the mating groove, the positioning accuracy between the pressure plate and the support base can be further enhanced during the processing, and the accuracy of the side edge processing position of the airbag mounting plate can be improved, thereby improving product quality.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When stamping the side edge of the airbag mounting plate, the workpiece to be stamped is placed on the support base, and the upper template is driven to press down. During this process, the inclined push panels on both sides of the lower press base push the drive block and the outer pressure block to slide in opposite directions through the inclined surfaces. The sliding of the drive block causes the inner abutment block to slide in the same direction, thereby realizing the relative sliding between the inner abutment block and the outer pressure block until the inner abutment block and the outer pressure block clamp and form the edge. This is because the inclined surfaces of the inclined side panel and the inclined push panel cooperate to convert the vertical downward force of the upper template into the horizontal relative motion force of the inner abutment block and the outer pressure block, thereby completing the clamping and forming of the edge in one go, without the need for multiple clamping and positioning, improving the work efficiency of processing the side edge of the mounting plate, improving the bending accuracy of the side edge, and enhancing the product quality and subsequent airbag assembly compatibility.

[0026] 2. After the side edge stamping of the airbag mounting plate is completed, the upper template rises and drives the lower pressure seat to rise. The insertion part of the reset clamp slides in the insertion guide groove and pushes against its upper inner side wall, so that the outer pressure block slides synchronously away from the inner block and automatically resets to the initial position, which facilitates the next edge-sealing operation. There is no need to manually adjust the position of the outer pressure block, which improves the working efficiency and automation of the side edge-sealing mechanism and reduces the error and time cost caused by manual intervention.

[0027] 3. The supporting slide plate can support the sliding outer pressure block, reduce the friction between the outer pressure block and the moving plate, and make the outer pressure block slide more smoothly in the second slide groove. This helps to improve the operational stability and working efficiency of the side edging mechanism of the airbag mounting plate. Attached Figure Description

[0036] The following is in conjunction with the appendix Figures 2-6 This application will be described in further detail.

[0037] This application discloses a side-wrapping mechanism for an airbag mounting plate.

[0038] Reference Figure 2 and Figure 3 An airbag mounting plate side edge wrapping mechanism includes a lower template 1, an upper template 2, and a pressing template 3. The upper template 2 is located directly above the lower template 1. A support seat 4 for placing the workpiece to be stamped is fixedly installed on the lower template 1. The pressing template 3 is installed at the bottom of the upper template 2 and is used to press the top wall of the mounting plate 01 against the support seat 4 when the upper template 2 is pressed down.

[0039] Reference Figure 3 , Figure 4 and Figure 5 A vertically arranged elastic telescopic member 5 connects the pressing template 3 and the upper template 2. The elastic telescopic member 5 can be a gas spring or a nitrogen spring. In this embodiment, a nitrogen spring is used as an example. Its two ends are respectively assembled and connected to the pressing template 3 and the upper template 2. A vertical positioning rod 21 is also fixedly provided at the bottom of the upper template 2. The support base 4 has a positioning hole 41 that is inserted and engaged with the positioning rod 21. The positioning rod 21 slides through the pressing template 3 and is in sliding engagement with the pressing template 3. During the side edge stamping process of the airbag mounting plate, the bottom end of the positioning rod 21 passes through the opening 011 of the mounting base plate 01 and is inserted into the positioning hole 41.

[0040] Reference Figure 4 and Figure 6 In order to improve the docking accuracy between the pressing template 3 and the support base 4 during the processing, the bottom of the pressing template 3 is provided with multiple docking grooves 31, and the top of the support base 4 is fixedly provided with multiple docking protrusions 42. The docking protrusions 42 and the docking grooves 31 correspond one to one and are inserted into each other.

[0041] Reference Figure 3 and Figure 4 The lower template 1 has first sliding grooves 11 on both sides of the support base 4. The first sliding grooves 11 are arranged along the length direction perpendicular to the support base 4, and a movable plate 6 is slidably arranged in each first sliding groove 11. A guide groove 111 is formed in the first sliding groove 11, and a slider 1111 and an elastic reset member 1112 are arranged in the guide groove 111. The elastic reset member 1112 can be a compression spring or a nitrogen spring. In this embodiment, a nitrogen spring is used as an example. The two ends of the nitrogen spring are fixedly connected to the inner end wall of the guide groove 111 and the side wall of the slider 1111, respectively. The nitrogen spring has good elasticity and buffering performance. When the upper template 2 is pressed down, the nitrogen spring is compressed, which plays a role in buffering and energy storage; when the upper template 2 is raised, the nitrogen spring releases energy and pushes the movable plate 6 to reset.

[0042] Reference Figure 4An inner abutment block 61, made of metal, is fixedly installed at one end of the mobile plate 6 near the support base 4. Its shape is designed according to the shape of the edge binding part 03. The inner abutment block 61 is used to abut the edge binding part 03 from the inside during the edge binding process, playing a role in positioning and initial shaping. A drive block 62 is fixedly installed at the other end of the mobile plate 6 away from the support base 4.

[0043] Reference Figure 4 The top of the movable plate 6 is parallel to the length direction of the first slide groove 11 and has multiple supporting slide plates 63 and a second slide groove 64. The supporting slide plates 63 and the second slide groove 64 are staggered and fixed to the movable plate 6. The second slide groove 64 is recessed into the top wall of the movable plate 6, and an outer pressure block 7, which is inserted into the inner abutment block 61, is slidably disposed within the second slide groove 64. The outer pressure block 7 is also made of metal and is inserted into the inner abutment block 61. The bottom of the outer pressure block 7 is slidably supported on the multiple supporting slide plates 63. The supporting slide plates 63 support the outer pressure block 7 and reduce the sliding resistance of the outer pressure block 7, making the sliding of the outer pressure block 7 smoother.

[0044] Reference Figure 4 A nitrogen spring is also installed in each of the second slide grooves 64. Its size matches the second slide groove 64, and its two ends are respectively fixedly connected to the inner end wall of the second slide groove 64 and the side wall of the outer pressure block 7 located in the second slide groove 64.

[0045] Reference Figure 2 , Figure 4 and Figure 5 The drive block 62 and the outer pressure block 7, located on the same side of the support base 4, are both fixedly provided with inclined side panels 621 on opposite sides, and the tops of the two inclined side panels 621 extend in opposite directions. The upper template 2 is fixedly provided with a lower pressure seat 22 between each set of drive blocks 62 and outer pressure blocks 7. The two sides of the lower pressure seat 22 are fixedly provided with inclined push panels 221 in conjunction with the inclined side panels 621.

[0046] Reference Figure 3 When the upper template 2 is pressed down, the lower pressing seat 22 descends accordingly. The inclined push panels 221 on both sides of the lower pressing seat 22 push the drive block 62 and the outer pressing block 7 to slide in opposite directions through the inclined surfaces. The sliding of the drive block 62 causes the inner abutment block 61 to slide in the same direction, thereby realizing the relative sliding between the inner abutment block 61 and the outer pressing block 7 until the inner abutment block 61 and the outer pressing block 7 clamp and form the edge-wrapping part 03. This is because the inclined surfaces of the inclined side panel 621 and the inclined push panel 221 cooperate to convert the vertical downward force of the upper template 2 into the horizontal relative movement force of the inner abutment block 61 and the outer pressing block 7, thereby realizing the edge-wrapping operation.

[0047] Reference Figure 4 and Figure 5To ensure accurate repositioning of the outer pressure block 7, repositioning clamps 8 are fixedly installed on both side walls of the lower pressure seat 22 adjacent to the outer pressure block 7. Each repositioning clamp 8 includes a support portion 81 and a insertion portion 82. One end of the support portion 81 is fixedly mounted on the side wall of the lower pressure seat 22, and the insertion portion 82 is vertically fixed to the other end of the support portion 81. Two insertion portions 82 on the same lower pressure seat 22 are arranged opposite each other, and an insertion guide groove 71 is formed on the side wall of the outer pressure block 7 parallel to the inclined side panel 621. The top of the insertion guide groove 71 extends to the top wall of the outer pressure block 7. The insertion portion 82 is inserted through the top opening of the insertion guide groove 71 and slides in cooperation with it. When the upper template 2 rises, the insertion portion 82 pushes against the upper inner side wall of the insertion guide groove 71, causing the outer pressure block 7 to slide synchronously toward the side away from the inner abutment block 61, thus achieving automatic repositioning of the outer pressure block 7.

[0048] Reference Figure 4 To determine whether the reset position of the outer pressure block 7 is accurate, a calibration rod 9 is fixedly installed on the side wall of the outer pressure block 7. A proximity switch 91 that aligns with the calibration rod 9 is installed on the lower template 1. When the outer pressure block 7 is reset, the calibration rod 9 aligns with the proximity switch 91, which indicates that the reset position of the outer pressure block 7 is accurate, and the subsequent side edge processing of the workpiece can continue.

[0049] The implementation principle of the side edging mechanism for an airbag mounting plate according to an embodiment of this application is as follows: When processing the side edging of the airbag mounting plate, the workpiece to be stamped is first placed on the support base 4. Then, the upper template 2 is pressed down, and the die presses the mounting base plate 01 onto the support base 4. At the same time, the positioning rod 21 is inserted into the opening 011 of the mounting base plate 01 and into the positioning hole 41 on the support base 4, ensuring the accurate positioning of the upper template 2 and the lower template 1.

[0050] As the upper template 2 is pressed down, the lower pressure seat 22 also descends. Its inclined push panel 221 pushes the drive block 62 and the outer pressure block 7 to slide relative to each other, so that the inner abutment block 61 and the outer pressure block 7 clamp and shape the edge part 03.

[0051] After processing, the upper template 2 rises, the reset clamping plate 8 drives the outer pressure block 7 to reset, and the nitrogen spring pushes the moving plate 6 to reset. The entire process, through the coordinated work of various components, achieves efficient and precise side edge processing, avoids problems caused by multiple clamping, improves production efficiency and product quality, and represents a significant improvement and enhancement compared to existing technologies.

[0052] 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.
