Description

Technical Field

[0001] This application relates to the field of sealing strip processing technology, and in particular to a sawing and bending device for sealing strips. Background Technology

[0002] Sealing strips play a vital role in the automotive industry, widely used in the joints of car doors, windows, sunroofs, and other areas. By installing sealing strips, gaps between body components are effectively filled, forming a physical barrier. Sealing strips effectively prevent rainwater, dust, and pollutants from entering the vehicle interior through these gaps, protecting electronic equipment and interior materials from damage and extending the vehicle's lifespan. By filling these gaps, sealing strips significantly reduce wind noise, tire noise, and external noise during driving, improving cabin quietness and optimizing ride comfort.

[0003] To meet the installation requirements of different vehicle models or locations, the angles of their end faces vary, and some sealing strips need to be pre-bent according to installation standards. A common processing solution is to separate sawing and bending into two steps, and perform the processing on two separate processing machines.

[0004] Related prior art, such as the Chinese patent application "Bending Device for Automotive Sealing Strips", publication number: CN111113863A, discloses a device including a substrate, a reference block and a first pressing block disposed opposite each other on the substrate, the surfaces of the reference block and the first pressing block being standard curved surfaces, an elastic sheet disposed between the reference block and the pressing block, one end of the elastic sheet being fixed to the substrate, and the other end of the elastic sheet being connected to a power device, the sealing strip being snapped onto the elastic sheet along the length direction of the elastic sheet, the power device driving the elastic sheet to bend and completely fit against the standard curved surface of the reference block, a second pressing block being disposed above the reference block, the first pressing block and the second pressing block being respectively connected to the power device, the power device driving the first pressing block to move horizontally and press against the elastic sheet fitted against the standard curved surface, and the power device driving the second pressing block to press vertically downward and act on the elastic sheet and the standard curved surface.

[0005] For example, the Chinese patent application "Integrated Saw and Punch Cutting Mold Structure", publication number CN117124389A, discloses a structure including: a support frame with a support platform, a support block on the support platform, a first mounting groove for installing a sealing strip on the support block, and a first cutting groove and a second cutting groove corresponding to each other on the support block; a motor, the output shaft of which is connected to a saw blade for sawing the sealing strip, the saw blade being located in the first cutting groove or the second cutting groove; a moving unit, located on the support frame and connected to the motor; and a punching unit, including a fixed seat on the support frame and two slicing blades on the fixed seat, the length directions of the two slicing blades being perpendicular to each other, and a second mounting groove for installing the sealing strip being provided on the fixed seat.

[0006] In the aforementioned patent application, the sawing and bending of the sealing strip were performed using two separate machines. Processing the sealing strip requires transferring it from one machine to the other, increasing workpiece transfer time and equipment preparation time, thus prolonging the overall processing time. Since processing is done on two separate machines, cumulative errors may occur. Since sawing and bending are performed on different machines, differences in precision between the machines and positional shifts during workpiece transfer may result in lower final processing accuracy. Utility Model Content

[0007] The technical problem to be solved by this application is to provide a sawing and bending device for sealing strips, which can effectively improve the processing efficiency and accuracy of sealing strips, reduce costs, and simplify operation.

[0008] The technical solution adopted in this application is as follows: a sawing and bending device for sealing strips, including a base plate, on which a mounting seat for mounting the sealing strip to be processed is provided, a power device is connected to the mounting seat and drives the mounting seat to bend backward, a first sawing component and a second sawing component are respectively provided at both ends of the mounting seat, a slot and a hole are opened on the surface of the base plate, the slot and the hole are respectively located at both ends of the mounting seat, a slider is movably installed in the slot, the first sawing component is installed on the slider, the slider moves and drives the first sawing component to move closer to or away from the mounting seat, the second sawing component is arranged below the base plate, the second sawing component includes a second saw blade and a longitudinal power cylinder, the top of the second saw blade of the second sawing component extends out of the slot, the longitudinal power cylinder moves and drives the second saw blade to move within the range of the slot.

[0009] Compared with existing technologies, the advantages of this application are that it integrates sawing and bending functions onto a single substrate, avoiding the cumbersome process of requiring two separate machines for sawing and bending in traditional processing. This integrated design significantly reduces workpiece transfer time and equipment preparation time, thereby improving overall processing efficiency. Since sawing and bending operations are completed on the same machine, the cumulative errors that may result from processing with two separate machines in the past are avoided. The automated bending function of the power unit further ensures consistent precision during processing, improving the quality of the final product.

[0010] This application utilizes a slider and slot design, allowing the first sawing assembly to move along the slider, closer to or further away from the mounting base. This design provides flexible adjustment capabilities to accommodate the processing needs of sealing strips of different lengths and specifications. Furthermore, during sealing strip installation, the first and second sawing assemblies can be positioned outwards to facilitate installation.

[0011] The second sawing component is positioned below the substrate, while the first sawing component is recessed via a slot. This design not only reduces the equipment's footprint but also optimizes the overall structural layout, making it more suitable for small-scale production scenarios.

[0012] In some embodiments of this application, the first sawing assembly is mounted on a frame, the frame is connected to a slider via a base, the base and the slider are rotatably connected via a vertical pivot, and the frame is rotatably connected to the base via a horizontal pivot.

[0013] Through multi-dimensional rotational connection of the vertical and horizontal axes, the first sawing component achieves flexible angle adjustment in both vertical and horizontal planes. This design significantly improves the adaptability of the equipment, enabling it to meet the processing needs of sealing strips of different specifications and angles.

[0014] In some embodiments of this application, a slide rail is provided below the substrate along the slot direction, the slider is mounted on the slide rail, the slider is connected to a transverse power cylinder, and the transverse power cylinder drives the frame to move along the length direction of the slot.

[0015] The design of the slide rail and lateral power cylinder allows the frame to move smoothly along the slot direction, enabling automatic feeding and retraction of the sawing components. The downward-sloping design of the slide rail not only improves the ease of operation but also optimizes the structural layout of the equipment, reduces the overall height, and enhances its compactness.

[0016] In some embodiments of this application, the frame is a rectangular frame structure with two guide columns arranged in parallel on the frame. The first sawing assembly is mounted on a slide plate, which is movably mounted on the frame. The guide columns pass through the slide plate. A downward power cylinder is mounted on the frame, and the power shaft of the downward power cylinder is connected to the slide plate. The downward power cylinder drives the slide plate to move along the guide columns.

[0017] The rectangular frame structure and guide column design enhance the stability and rigidity of the frame, ensuring the straightness of the slide during movement. The use of a downward power cylinder further improves the motion accuracy of the sawing components, ensuring the stability and reliability of the sawing process.

[0018] In some embodiments of this application, the first sawing assembly includes an outer cover and a first saw blade located inside the outer cover. The outer cover is connected to a slide plate via an elastic component. The rotary motor is fixedly mounted on the slide plate, and the power shaft of the rotary motor extends into the outer cover and is connected to the first saw blade.

[0019] The flexible component design makes the outer casing a movable part relative to the slide and rotary motor. The casing also provides protection, preventing debris from splashing and improving operational safety.

[0020] In some embodiments of this application, the rear side of the outer cover is provided with a waist-shaped hole, and the length direction of the waist-shaped hole is the height direction of the outer cover; after the outer cover moves to the sawing position, it reaches the limit position, at which time the slide can drive the rotary motor and saw blade to continue to move downward to saw the sealing strip.

[0021] The oblong hole design provides the saw blade with extra room to maneuver, allowing it to continue cutting downwards after the outer casing reaches its limit position. This design improves the flexibility of the equipment and prevents debris from splashing during processing.

[0022] In some embodiments of this application, a positioning seat is provided on the substrate, and two positioning pins are installed on the rear side of the outer cover. When the outer cover is moved to the sawing position, the bottom of the positioning pin is inserted into the positioning seat. The bottom of the positioning pin has a conical structure. The positioning seat is located on the front side of the mounting seat, and the rear side of the positioning seat forms the grid surface on the front side of the sealing strip.

[0023] The design of the locating pin and locating seat provides precise positioning, ensuring the accuracy of the outer cover in the sawing position. The tapered structure facilitates insertion and positioning, while the grid surface of the locating seat provides stable support for the sealing strip, improving sawing precision.

[0024] In some embodiments of this application, a molding seat is provided on the rear side of the mounting base, and the molding seat is equipped with a plurality of standard blocks. The standard blocks are detachably connected to the molding seat, and the outer surface of the standard blocks constitutes the side reference surface for the bending and forming of the sealing strip.

[0025] The detachable connection design of the forming base and standard block allows for quick replacement of the standard block according to different bending requirements, improving the flexibility and adaptability of the equipment. The side reference surface provides a precise bending reference, ensuring the fit and forming accuracy of the sealing strip during the bending process.

[0026] In some embodiments of this application, the forming seat is provided with a pressure block connected to the downward pressing power cylinder. The structure of the pressure block is adapted to the structure of the standard block. The pressure block is located directly above the side reference plane, and the bottom surface of the pressure block constitutes the upper reference plane for the bending and forming of the sealing strip.

[0027] The combination of the pressure block and the downward-pressing cylinder applies downward pressure to the sealing strip during bending, further improving the bending accuracy and stability. The bottom surface of the pressure block is aligned with the side reference surface, ensuring the sealing strip fits snugly during bending and preventing wrinkles or deformation.

[0028] In some embodiments of this application, the mounting base is a bendable structure, and an embedding groove is provided at the bottom of the outer peripheral surface of the forming base. The embedding groove is adapted to the rear end structure of the mounting base. When the sealing strip is attached to the side reference surface, the rear end of the mounting base is inserted into the embedding groove. The bendable mounting base design enhances the flexibility of the equipment and can adapt to bending requirements at different angles. The embedding groove design ensures the stability of the mounting base during the bending process, avoids shaking, and improves the forming quality after bending.

[0037] The present application will now be described in detail with reference to the accompanying drawings.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] A sawing and bending device for sealing strips, as described in Embodiment 1 Figures 1 to 2 As shown: A base plate 1 is included, on which a mounting seat 35 for mounting a sealing strip to be processed is provided. A power device 34 is connected to the mounting seat 35 and drives the mounting seat 35 to bend backward. A first sawing component 4 and a second sawing component 30 are respectively provided at both ends of the mounting seat 35. A slot 5 and a hole 33 are formed on the surface of the base plate 1, located at both ends of the mounting seat 35. A slider 6 is movably mounted in the slot 5. The first sawing component 4 is mounted on the slider 6. The slider 6 moves, causing the first sawing component 4 to move closer to or away from the mounting seat 35. This application, through the design of the slider 6 and the slot 5, allows the first sawing component 4 to move along the slider 6, moving closer to or away from the mounting seat 35. This design provides flexible adjustment capabilities, adapting to the processing needs of sealing strips of different lengths and specifications. The second sawing assembly 30 is disposed below the substrate 1. The second sawing assembly 30 includes a second saw blade 31 and a longitudinal power cylinder 32. The top of the second saw blade 31 extends from the slot 5. The movement of the longitudinal power cylinder 32 drives the second saw blade 31 to move within the range of the slot 33. When installing the sealing strip, the first sawing assembly 4 and the second sawing assembly 30 can be positioned outwards for easy installation. The second sawing assembly 30 is disposed below the substrate 1, while the first sawing assembly 4 is recessed through the slot 5. This design not only reduces the footprint of the equipment but also optimizes the overall structural layout, making it more suitable for small-scale production scenarios.

[0040] This application integrates sawing and bending functions onto a single substrate 1, avoiding the cumbersome process of requiring two separate machines for sawing and bending in traditional processing. This integrated design significantly reduces workpiece transfer time and equipment preparation time, thereby improving overall processing efficiency. Since sawing and bending operations are completed on the same machine, the cumulative errors that may occur with traditional two-machine processing are avoided. The automated bending function of the power unit 34 further ensures consistency of precision during processing, improving the quality of the final product.

[0041] Example 2, as Figures 1 to 5 As shown, the first sawing assembly 4 is mounted on the frame 3. The frame 3 is connected to the slider 6 via the base 2. The base 2 and slider 6 are rotatably connected via a vertical rotating shaft 7. The frame 3 is rotatably connected to the base 2 via a horizontal rotating shaft 8. Through the multi-dimensional rotational connection of the vertical and horizontal rotating shafts 7 and 8, flexible angle adjustment of the first sawing assembly 4 in both vertical and horizontal planes is achieved. This design significantly improves the adaptability of the equipment and can meet the processing requirements of sealing strips of different specifications and angles.

[0042] A slide rail 11 is provided below the base plate 1 along the direction of the slot 5. A slider 6 is mounted on the slide rail 11 and connected to a transverse power cylinder 12. The transverse power cylinder 12 drives the frame 3 to move along the length of the slot 5. The design of the slide rail 11 and the transverse power cylinder 12 allows the frame 3 to move smoothly along the direction of the slot 5, realizing automatic feeding and retraction of the sawing assembly. The downward design of the slide rail 11 not only improves the convenience of operation but also optimizes the structural layout of the equipment, reduces the overall height, and enhances compactness.

[0043] The frame 3 is a rectangular frame structure with two parallel guide posts 16 arranged on it. The first sawing assembly 4 is mounted on a slide plate 17, which is movably mounted on the frame 3. The guide posts 16 pass through the slide plate 17. A downward power cylinder 9 is mounted on the frame 3, and its power shaft is connected to the slide plate 17. The downward power cylinder 9 drives the slide plate 17 to move along the guide posts 16. The rectangular frame structure and the design of the guide posts 16 enhance the stability and rigidity of the frame 3, ensuring the straightness of the slide plate 17 during movement. The use of the downward power cylinder 9 further improves the motion accuracy of the sawing assembly, ensuring the stability and reliability of the sawing process.

[0044] The first sawing assembly 4 includes an outer cover 18 and a first saw blade 19 located inside the outer cover 18. The outer cover 18 is connected to a slide plate 17 via an elastic component 20. The rotary motor 10 is fixedly mounted on the slide plate 17, and the power shaft of the rotary motor 10 extends into the outer cover 18 and is connected to the first saw blade 19. The design of the elastic component 20 makes the outer cover 18 a movable part relative to the slide plate 17 and the rotary motor 10. The design of the outer cover 18 provides a protective function, preventing residue from splashing and improving operational safety.

[0045] The outer cover 18 has a waist-shaped hole 28 on its rear side, the length of which corresponds to the height of the outer cover 18. After the outer cover 18 moves to the sawing position, it reaches its limit position. At this point, the slide plate 17 can drive the rotary motor 10 and the saw blade to continue moving downwards to saw the sealing strip. The design of the waist-shaped hole 28 provides additional movement space for the saw blade, allowing it to continue moving downwards to saw after the outer cover 18 reaches its limit position. This design improves the flexibility of the equipment and avoids debris splashing during processing.

[0046] A positioning seat 63 is provided on the base plate 1, and two positioning pins 27 are installed on the rear side of the outer cover 18. When the outer cover 18 moves to the sawing position, the bottom of the positioning pins 27 is inserted into the positioning seat 63. The bottom of the positioning pins 27 has a conical structure. The positioning seat 63 is located on the front side of the mounting base 35, and the rear side of the positioning seat 63 forms the grid surface on the front side of the sealing strip. The design of the positioning pins 27 and the positioning seat 63 provides a precise positioning function, ensuring the accuracy of the outer cover 18 in the sawing position. The conical structure facilitates insertion and positioning, while the grid surface of the positioning seat 63 provides stable support for the sealing strip, improving the sawing accuracy.

[0048] Example 3, as Figures 1 to 5 As shown, a forming seat 66 is provided on the rear side of the mounting base 35. The forming seat 66 is equipped with several standard blocks 67, which are detachably connected to the forming seat 66. The outer surface of the standard blocks 67 forms the side reference surface 68 for bending the sealing strip. The detachable connection design between the forming seat 66 and the standard blocks 67 allows for quick replacement of the standard blocks 67 according to different bending requirements, improving the flexibility and adaptability of the equipment. The side reference surface 68 provides a precise bending reference, ensuring the fit and forming accuracy of the sealing strip during the bending process.

[0049] The forming seat 66 is provided with a pressure block 69 connected to the downward pressing power cylinder 70. The structure of the pressure block 69 is adapted to the structure of the standard block 67. The pressure block 69 is located directly above the side reference surface 68, and the bottom surface of the pressure block 69 forms the upper reference surface 71 for bending the sealing strip. The cooperation between the pressure block 69 and the downward pressing power cylinder 70 ensures that the sealing strip is subjected to downward pressure during the bending process, further improving the bending accuracy and stability. The adaptation of the bottom surface of the pressure block 69 to the side reference surface 68 ensures the fit of the sealing strip during the bending process, avoiding wrinkles or deformation.

[0050] The mounting base 35 is a bendable structure, and the bottom of the outer peripheral surface of the forming base 66 is provided with an embedding groove 76, which is adapted to the rear end structure of the mounting base 35. When the sealing strip is attached to the side reference surface 68, the rear end of the mounting base 35 is inserted into the embedding groove 76. The bendable design of the mounting base 35 enhances the flexibility of the equipment and can adapt to bending requirements at different angles. The design of the embedding groove 76 ensures the stability of the mounting base 35 during the bending process, avoids shaking, and improves the forming quality after bending.
