Description

Technical Field

[0001] This application relates to the technical field of the processing of sealing strips, and in particular to an automatic sawing and bending integrated machine for sealing strips. Background Art

[0002] Sealing strips play an important role in the automotive industry and are widely used at joints such as car doors, windows, and sunroofs. By installing sealing strips, the gaps between body components are effectively filled, forming a physical barrier. The sealing strips can effectively prevent rainwater, dust, and pollutants from invading the vehicle interior through the gaps, protect the in-vehicle electronic devices and interior trim from damage, and extend the service life of the vehicle. By filling the gaps between body components, the sealing strips significantly reduce the transmission of wind noise, tire noise, and external noise during driving, improve the interior quietness of the vehicle, and optimize the driving and riding comfort.

[0003] In order to meet the installation requirements of different vehicle models or different positions, the angles of their end faces are different, and some sealing strips need to be pre-bent according to the installation standards. The common processing scheme is to divide sawing and bending into two steps and perform the processing on two processing devices respectively.

[0004] Related prior art such as the Chinese patent application "Bending Device for Automotive Sealing Strips", publication number: CN111113863A, discloses including a base plate, a reference block and a first pressing block oppositely arranged on the base plate. The opposite surfaces of the reference block and the first pressing block are standard curved surfaces. An elastic sheet is arranged between the reference block and the pressing block. One end of the elastic sheet is fixed to the base plate, and the other end of the elastic sheet is connected to a power device. The sealing strip is clamped on the elastic sheet along the length direction of the elastic sheet. The power device will drive the elastic sheet to bend and completely fit on the standard curved surface of the reference block. A second pressing block is also arranged above the reference block. The first pressing block and the second pressing block are respectively connected to the power device. The power device drives the first pressing block to horizontally move and press on the elastic sheet that fits on the standard curved surface, and the power device drives the second pressing block to vertically press on the elastic sheet and the standard curved surface.

[0005] Another example is the Chinese patent application "Integrated Die Structure for Sawing and Punching", publication number: CN117124389A, which discloses including: a support frame provided with a bearing platform, a bearing block arranged on the bearing platform, a first installation groove for installing a sealing strip is opened on the bearing block, and a first cutting groove and a second cutting groove corresponding to each other are opened on the bearing block; a motor, the output shaft of which is connected with a sawing knife for sawing the sealing strip, and the sawing knife is located in the first cutting groove or the second cutting groove; a moving unit arranged on the support frame and connected with the motor; and a punching unit including a fixed seat arranged on the support frame and two scoring knives arranged on the fixed seat. The length directions of the two scoring knives are perpendicular to each other, and a second installation groove for installing a sealing strip is opened on the fixed seat.

[0006] In the above patent application, two devices are used for sawing and bending the sealing strip. Sawing and bending are carried out on different devices respectively. Due to the precision difference between the devices and the position deviation during the workpiece transfer process, the final processing precision may be low. In the above patent application, an elastic sheet is used as the carrier for installation and bending of the sealing strip. However, this solution still has certain limitations in practical applications. The elastic sheet itself has a certain elastic restoring force. When the sealing strip needs to be bent at a large angle, the restoring force of the elastic sheet will exert a reverse force on the sealing strip, resulting in a large springback phenomenon after the sealing strip is bent. This springback will affect the forming precision of the sealing strip and may even cause the sealing strip to fail to meet the installation requirements. Summary of the Invention

[0007] The technical problem to be solved by this application is to provide an automatic sawing and bending machine for sealing strips, which can effectively improve the processing efficiency and precision of the sealing strips and solve the problem of large springback after bending the sealing strips.

[0008] The technical solution adopted by this application is as follows: an automatic sawing and bending machine for sealing strips, including a base plate. An installation seat for installing the sealing strip to be processed is arranged on the base plate. The installation seat consists of a first section, a second section and a third section connected in sequence. Both the first section and the third section are long strip-shaped block structures. The first section and the third section are respectively rotatably connected to both ends of the second section. The second section includes a plurality of vertical guide pieces connected by rotation. The sealing strip to be processed is inserted into the vertical guide pieces. A tensioning component is rotatably connected to the third section and drives the first section and the second section to bend backward. First sawing components and second sawing components are respectively arranged at both ends of the installation seat. A notch is formed on the surface of the base plate. A slider is movably installed in the notch. The first sawing component is installed on the slider. The slider moves the first sawing component to approach or move away from the installation seat.

[0009] Compared with the prior art, the advantages of this application are as follows: First, by integrating the first sawing component, the second sawing component and the bending component on the same base plate, continuous processing of sawing and bending is realized. This design avoids the positioning deviation caused by the transfer of the sealing strip in the traditional process, reduces the precision loss between processing links, and significantly improves the processing efficiency.

[0010] Secondly, the installation seat adopts a structure in which the first section, the second section and the third section are rotatably connected. Among them, the second section fixes the sealing strip through a plurality of vertical guide pieces connected by rotation. The design of low elastic restoring force between the vertical guide pieces effectively reduces the springback phenomenon after bending and ensures the forming precision of the sealing strip. The tensioning component drives the installation seat to bend in sections, which can flexibly adapt to different angle and shape bending requirements, especially suitable for the processing of sealing strips that need to be bent at a large angle.

[0011] Finally, the first sawing component is movably installed in the substrate notch through a slider. The movement of the slider drives the sawing component to approach or move away from the mounting seat, realizing the rapid adjustment of the sawing position. This structure eliminates the need for complex disassembly or repositioning, simplifies the operation process, and simultaneously ensures precise control of the sawing depth and angle. The first sawing component and the second sawing component are respectively arranged at both ends of the mounting seat, enabling simultaneous sawing of both ends of the sealing strip, reducing the processing time, and is particularly suitable for sealing strip products that require synchronous processing at both ends. The design of the notch, slider, and integrated mounting seat of the substrate reduces the overall volume of the equipment, is particularly suitable for small-scale production scenarios, and at the same time maintains the independence and maintainability of the functional modules.

[0012] In some embodiments of the present application, the second section includes a plurality of base blocks and a plurality of connecting blocks. The base block is an inverted T-shaped structural block, which includes a horizontal plate and a vertical plate. A vertical guide piece is installed at the top of the vertical plate. Adjacent two base blocks are connected by a connecting block. The connecting block has a runway-shaped structure and is erected on the horizontal plate of the base block. Both ends of the connecting block are respectively rotatably connected to two adjacent base blocks. A vertical guide piece is installed at the top of the connecting block. There is a spacing between adjacent two vertical guide pieces, and there is a gap between adjacent two horizontal plates.

[0013] The combined design of the inverted T-shaped base block and the runway-shaped connecting block enhances the mechanical stability of the second section. At the same time, through the rotational connection, flexible bending of multiple sections can be achieved. The elastic restoring force between the vertical guide pieces is low, effectively reducing the rebound of the sealing strip after bending and ensuring the forming accuracy.

[0014] In some embodiments of the present application, a forming seat is provided at the rear side of the mounting seat. The forming seat is provided with a number of standard blocks, and the standard blocks are detachably connected to the forming seat. The outer surface of the standard block constitutes the side reference plane for the bending forming of the sealing strip. The tensioning component moves to drive the sealing strip to bend backward until the sealing strip fits on the side reference plane.

[0015] The detachable standard blocks provide side reference planes with different bending angles, adapting to diverse bending requirements and enhancing the versatility of the equipment. The side reference plane serves as the bending reference, ensuring the bending fit of the sealing strip and improving the processing consistency.

[0016] In some embodiments of the present application, a pressing block connected to the downward pressure cylinder is provided on the forming seat. The structure of the pressing block is adapted to the structure of the standard block, and the pressing block is located directly above the side reference plane. The bottom surface of the pressing block constitutes the upper reference plane for the bending forming of the sealing strip. The bottom surface of the pressing block is a curved surface, and the top surface structure formed by all the vertical guide pieces fitting on the side reference plane is adapted to the bottom surface structure of the pressing block.

[0017] The cooperation of the curved pressing block and the side reference plane applies pressure in the Z-axis direction to achieve three-dimensional bending forming. At the same time, it also avoids unexpected deformation or wrinkles of the sealing strip, improving the accuracy of bending complex shapes.

[0018] In some embodiments of the present application, an embedding groove is provided at the bottom of the outer peripheral surface of the forming seat. The embedding groove is adapted to the structure of the rear end of the cross plate, and an avoidance groove is provided on the surface of the standard block corresponding to the retaining piece; when the sealing strip is attached to the side reference surface, the rear end of the cross plate of the connecting block is inserted into the embedding groove, and the retaining piece is embedded into the avoidance groove.

[0019] The embedding groove locks the cross plate of the connecting block, and the avoidance groove accommodates the retaining piece to eliminate structural interference, ensuring that the sealing strip fits perfectly with the reference surface when bent, preventing displacement deviation, and further guaranteeing the forming accuracy.

[0020] In some embodiments of the present application, the first section is an installation strip. A notch for sawing and processing by the second sawing assembly is provided in the middle of the installation strip.

A clamping strip is provided on the top surface of the installation strip along the length direction of the installation strip, and the clamping strip passes through between the two limiting walls; a pressing seat is correspondingly provided directly above the installation strip.

[0021] The notch provides a processing space for the second sawing assembly. The limiting walls and the clamping strip cooperate to fix the sealing strip, preventing the sealing strip from shifting during sawing. At the same time, the pressing seat provides additional clamping force to ensure processing stability. The setting of the limiting walls and the pressing seat also plays a role in fixing and limiting during the bending process, preventing the sealing strip from running off during the bending process.

[0022] In some embodiments of the present application, an auxiliary piece is provided at one end of the third section close to the second section. A retaining piece is provided at the rear side of the auxiliary piece. The retaining piece is arranged parallel to the auxiliary piece. The tail end of the sealing strip is installed on the auxiliary piece and is limited by the retaining piece at the rear side. A positioning seat is provided at the front side of the mounting seat, and the rear side surface of the positioning seat constitutes the blocking surface on the front side of the sealing strip; the side surfaces of the auxiliary piece and the retaining piece away from the second section constitute the auxiliary surface for sawing the tail end of the sealing strip. The auxiliary piece and the retaining piece limit the position of the tail end of the sealing strip, avoiding shaking and offset during bending or sawing; the auxiliary surface directly serves as the sawing positioning reference, simplifying the operation process and improving the end face processing accuracy.

[0023] In some embodiments of the present application, the first sawing assembly is installed on a sliding plate. The sliding plate is movably installed on the machine frame. A downward cylinder is installed on the machine frame and is connected to the sliding plate. The downward cylinder works to drive the sliding plate to move along the height direction of the machine frame; the machine frame is connected to the slider through a base. The base and the slider are rotatably connected through a vertical rotating shaft, and the machine frame is rotatably connected to the base through a horizontal rotating shaft; a slide rail is provided below the substrate along the direction of the notch. The slider is installed on the slide rail, and the slider is connected to a transverse power cylinder. The transverse power cylinder works to drive the machine frame to move along the length direction of the notch. The vertical rotating shaft and the horizontal rotating shaft provide angle adjustment in the vertical plane and the horizontal plane, and the slide rail and the transverse power cylinder achieve linear movement, adapting to different sawing positions and angle requirements, and improving processing flexibility.

[0024] In some embodiments of the present application, a plurality of first arc grooves are provided on the bottom surface of the frame. The first arc grooves are located on the outer periphery of the vertical rotating shaft, and the locking member is locked with the slider through the first arc grooves. A plurality of second arc grooves are provided on both side surfaces of the frame. The second arc grooves are located on the outer periphery of the horizontal rotating shaft, and the locking member is locked with the frame through the second arc grooves. By providing the arc grooves and the locking member, the flexibility of multi-angle adjustment is provided, and at the same time, the stability after adjustment is ensured, preventing angle deviation caused by vibration during the processing, and improving the processing accuracy. The arc grooves cooperate with the locking member to achieve rapid multi-angle adjustment and stable fixation, prevent angle deviation caused by processing vibration, and ensure sawing accuracy and repeatability.

[0025] In some embodiments of the present application, the substrate is provided with a curved track, and the tensioning assembly is located in the track and moves along the track. The tensioning assembly includes a tensioning power cylinder, which is horizontally arranged in the track and is on the same straight line as the first section, the second section, and the third section. The curved track guides the smooth movement of the tensioning assembly, and the tensioning power cylinder applies force to the mounting seat to ensure that the mounting seat moves straight backward, avoiding wrinkles in the sealing strip.

[0026] In some embodiments of the present application, an auxiliary plate is provided below the substrate. The auxiliary plate is arranged parallel to the substrate. A guide groove is provided on the auxiliary plate. A connecting plate is installed below the auxiliary plate. One end of the connecting plate is connected to a rotating shaft movably installed on the auxiliary plate, and the other end of the connecting plate is connected to a connecting rod. The rotating shaft is located at the center of the guide groove, and the connecting rod vertically passes through the guide groove and is connected to the tensioning power cylinder. The auxiliary plate and the guide groove provide additional support, and the transmission structure of the rotating shaft and the connecting rod enhances the movement stability of the tensioning assembly, reduces the overall height of the equipment, and optimizes the space utilization rate.

[0027] In some embodiments of the present application, a first cylinder is rotatably installed below the auxiliary plate. The output shaft of the first cylinder acts on the connecting plate and is movably connected to the connecting plate. An inner baffle and an outer baffle with an L-shaped cross-section are respectively provided below the auxiliary plate. Both ends of the connecting plate are respectively embedded in the inner baffle and the outer baffle.

[0028] In some embodiments of the present application, the frame is a rectangular frame structure. Two guide columns are arranged in parallel on the frame. The guide columns are passed through by a sliding plate. The downward power cylinder is installed on the frame, and the power shaft of the downward power cylinder is connected to the sliding plate. When the downward power cylinder works, it drives the sliding plate to move along the guide column. The frame adopts a rectangular frame structure and is provided with guide columns, which enhances the stability and rigidity of the structure, ensures the straightness of the first sawing assembly during movement, and improves the sawing accuracy and stability. The guide columns cooperate with the downward power cylinder to realize the straight downward pressure of the saw blade and reduce the processing vibration.

[0029] In some embodiments of the present 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 the sliding plate through an elastic assembly. The rotating motor is fixedly installed on the sliding plate. A waist-shaped hole is formed in the rear side surface of the outer cover, and the length direction of the waist-shaped hole is the height direction of the outer cover. The power shaft of the rotating motor extends into the outer cover through the waist-shaped hole and is connected to the first saw blade. A pressing plate is installed inside the outer cover, and the pressing plate is located below the first saw blade. When the outer cover moves downward until the pressing plate presses on the top surface of the sealing strip, the limit position of the movement of the outer cover is reached. At this time, the sliding plate continues to move downward, driving the rotating motor and the first saw blade to move downward to saw the sealing strip.

[0030] In the present application, through the movable connection of the outer cover, the pressing plate and the sliding plate, the pressing plate can elastically press and fix the sealing strip to be sawn, and cooperate with the subsequent sawing of the tail end of the sealing strip by the first saw blade. Moreover, the relatively movable outer cover can also provide good protection against the chips generated during sawing. The pressing plate presses and fixes the sealing strip through the elastic assembly to prevent the workpiece from displacing during sawing; the outer cover protects the chips, and the waist-shaped hole allows the saw blade to move independently downward, taking into account both safety protection and processing depth control.

[0031] In some embodiments of the present application, a mounting plate is installed on the rear side surface of the outer cover. The mounting plate is arranged parallel to the sliding plate and is connected to the sliding plate through an elastic assembly. The elastic assembly includes two parallel guide rods. A linear spring is sleeved outside the guide rods. One end of the linear spring abuts against the sliding plate, and the other end of the linear spring abuts against the mounting plate. The linear spring is in a compressed state. The outer cover is a relatively movable component with respect to the sliding plate.

[0032] In some embodiments of the present application, two parallel guide rails are arranged along the length direction of the rear side surface of the outer cover. Corresponding mounting blocks are provided on the mounting plate, and the mounting blocks are installed on the guide rails. The arrangement of the guide rails and the mounting blocks limits the movement trajectory of the outer cover relative to the mounting plate, ensures the stability and reliability of the outer cover during movement, prevents the outer cover from shifting or shaking, and at the same time reduces the wear of the outer cover.

[0033] In some embodiments of the present application, a strip-shaped mounting member is arranged in parallel on the front side of the mounting seat. A plurality of mounting holes are regularly formed along the length direction of the strip-shaped mounting member. The positioning seat can be adjustably installed on the mounting member through the mounting holes. The rear side surface of the positioning seat constitutes the front side stop surface of the sealing strip installed on the mounting seat. A sawing groove and a positioning groove are formed on the positioning seat. Two positioning pins are installed on the rear side surface of the outer cover. When the outer cover moves to the sawing position, the bottom of the positioning pin is inserted into the positioning seat, and the bottom of the first saw blade moves downward and extends into the positioning groove. The positioning seat is adjusted through multiple holes of the strip-shaped mounting member to adapt to sealing strips of different specifications.

[0034] The bottom of the positioning pin is a conical structure. The design of the positioning seat and the positioning pin provides an accurate positioning function, ensuring the accuracy of the outer cover at the sawing position. At the same time, the conical structure facilitates insertion and positioning.

[0035] In some embodiments of the present application, the front side of the outer cover is open and provided with a partition, and the partition is detachably connected to the outer cover. That is, the partition can be disassembled, so that the first saw blade is exposed, and the operator can replace the first saw blade.

[0036] In some embodiments of the present application, the second sawing assembly is installed below the substrate, and the second sawing assembly includes a second saw blade, and the top of the second saw blade protrudes from the substrate. Adding the second sawing assembly provides a double-headed sawing function, improves the versatility and processing efficiency of the equipment, can process the two end faces of the sealing strip at the same time, and reduces the processing time. Moreover, the second sawing assembly of the present application is designed below the substrate, and can be installed completely avoiding the installation position of the sealing strip, greatly reducing the floor space of the present application.

[0037] In some embodiments of the present application, the surface of the substrate is provided with a slot hole, and the second sawing assembly includes a longitudinal power cylinder. The longitudinal power cylinder drives the second saw blade to move, and the second saw blade moves within the range of the slot hole; the notch of the mounting strip is located above the slot hole. The surface of the substrate is provided with a slot hole and a longitudinal power cylinder, providing a moving space and power support for the second sawing assembly, and enhancing the flexibility and adaptability of the equipment.

[0042] The following will describe the present application in detail with reference to the accompanying drawings.

[0043] In order to make the purpose, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The automatic sawing and bending integrated machine for sealing strips, Example 1 is as Figure 1 、 Figure 2As shown in the figure: It includes a substrate 1, on which there is a mounting seat for mounting the sealing strip to be processed. The mounting seat consists of a first section 41, a second section 42, and a third section 43 that are connected in sequence. Both the first section 41 and the third section 43 are long strip-shaped block structures. The first section 41 and the third section 43 are respectively rotatably connected to both ends of the second section 42. The second section 42 includes a plurality of vertical guide pieces 47 that are rotatably connected. The sealing strip to be processed is inserted on the vertical guide pieces 47. The tensioning assembly 49 is rotatably connected to the third section 43 and drives the first section 41 and the second section 42 to bend backward. The mounting seat adopts a structure in which the first section 41, the second section 42, and the third section 43 are rotatably connected. Among them, the second section 42 fixes the sealing strip through a plurality of rotatably connected vertical guide pieces 47. The low elastic recovery force design between the vertical guide pieces 47 effectively reduces the springback phenomenon after bending and ensures the forming accuracy of the sealing strip; the tensioning assembly 49 drives the mounting seat to bend in sections, which can flexibly adapt to the bending requirements of different angles and shapes, especially suitable for the processing of sealing strips that require large-angle bending.

[0045] Both ends of the mounting seat are respectively provided with a first sawing assembly 4 and a second sawing assembly 30. By integrating the first sawing assembly 4, the second sawing assembly 30, and the bending assembly on the same substrate 1, continuous processing of sawing and bending is achieved. This design avoids the positioning deviation caused by the transfer of the sealing strip in the traditional process, reduces the accuracy loss between processing links, and significantly improves the processing efficiency at the same time. A notch 5 is opened on the surface of the substrate 1, and a slider 6 is movably installed in the notch 5. The first sawing assembly 4 is installed on the slider 6, and the slider 6 drives the first sawing assembly 4 to move closer to or away from the mounting seat. The first sawing assembly 4 is movably installed in the notch 5 of the substrate 1 through the slider 6. The slider 6 moves to drive the sawing assembly to move closer to or away from the mounting seat, realizing the rapid adjustment of the sawing position. This structure does not require complex disassembly or repositioning, simplifies the operation process, and at the same time ensures the precise control of the sawing depth and angle. The first sawing assembly 4 and the second sawing assembly 30 are respectively arranged at both ends of the mounting seat, and the two ends of the sealing strip can be sawed simultaneously, reducing the processing time, especially suitable for sealing strip products that require synchronous processing at both ends. The design of the notch 5, the slider 6, and the integrated mounting seat on the substrate 1 reduces the overall volume of the equipment, especially adapts to small-scale production scenarios, and at the same time maintains the independence and maintainability of the functional modules.

[0046] Embodiment 2, such as Figures 1 to 9As shown, the second section 42 includes a plurality of base blocks 72 and a plurality of connecting blocks 73. The base blocks 72 are inverted T-shaped structural blocks. The base block 72 includes a transverse plate 74 and a vertical plate 75. A vertical guide piece 47 is installed at the top of the vertical plate 75. Adjacent two base blocks 72 are connected by a connecting block 73. The connecting block 73 has a runway-shaped structure. The connecting block 73 is erected on the transverse plate 74 of the base block 72. Both ends of the connecting block 73 are rotatably connected to two adjacent base blocks 72 respectively. A vertical guide piece 47 is installed at the top of the connecting block 73. There is a spacing between adjacent two vertical guide pieces 47, and there is a gap between adjacent two transverse plates 74. The combined design of the inverted T-shaped base block 72 and the runway-shaped connecting block 73 enhances the mechanical stability of the second section 42. At the same time, multi-section flexible bending is realized through rotational connection. The elastic restoring force between the vertical guide pieces 47 is low, effectively reducing the rebound of the sealing strip after bending and ensuring the forming accuracy.

[0047] A forming seat 66 is arranged at the rear side of the mounting seat. The forming seat 66 is provided with a number of standard blocks 67. The standard blocks 67 are detachably connected to the forming seat 66. The outer surface of the standard block 67 constitutes a side reference surface 68 for the bending and forming of the sealing strip. The tensioning assembly 49 moves to drive the sealing strip to bend backward until the sealing strip fits on the side reference surface 68. The detachable standard block 67 provides side reference surfaces 68 with different bending angles, adapts to diversified bending requirements, and improves the versatility of the equipment; the side reference surface 68 serves as a bending reference, ensuring the bending fit degree of the sealing strip and improving the processing consistency.

[0048] A pressing block 69 connected to the downward pressure cylinder 70 is arranged on the forming seat 66. The structure of the pressing block 69 is adapted to the structure of the standard block 67. The pressing block 69 is located directly above the side reference surface 68; the bottom surface of the pressing block 69 constitutes an upper reference surface 71 for the bending and forming of the sealing strip. The bottom surface of the pressing block 69 is a curved surface, and the top surface structure formed by all the vertical guide pieces 47 that fit on the side reference surface 68 is adapted to the bottom surface structure of the pressing block 69. The curved pressing block 69 cooperates with the side reference surface 68 to apply pressure in the Z-axis direction to realize three-dimensional bending and forming. At the same time, it also avoids unexpected deformation or wrinkles of the sealing strip, and improves the accuracy of bending of complex shapes.

[0049] An embedding groove 76 is arranged at the bottom of the outer peripheral surface of the forming seat 66. The embedding groove 76 is adapted to the structure of the rear end of the transverse plate 74. An avoiding groove 77 corresponding to the retaining piece 62 is arranged on the surface of the standard block 67; when the sealing strip fits on the side reference surface 68, the rear end of the transverse plate 74 of the connecting block 73 is inserted into the embedding groove 76, and the retaining piece 62 is embedded into the avoiding groove 77. The embedding groove 76 locks the transverse plate 74 of the connecting block 73, and the avoiding groove 77 accommodates the retaining piece 62 to eliminate structural interference, ensuring that the sealing strip completely fits the reference surface during bending, preventing displacement deviation, and further guaranteeing the forming accuracy.

[0050] The first section 41 is an installation strip 44. A notch for the second sawing assembly 30 to perform sawing processing is provided in the middle of the installation strip 44.
