Description

Technical Field

[0001] This invention relates to the field of spring forming technology, specifically to a method and apparatus for forming springs for automotive panoramic sunroof windshields. Background Technology

[0002] Panoramic sunroofs are widely used in various car models and have become a standard feature in high-end car configurations. In current technology, panoramic sunroofs are generally equipped with a wind deflector, which is installed on the guide rail of the panoramic sunroof. The existing wind deflector usually requires the use of springs during installation. The wind deflector springs are usually made of metal materials with a certain amount of elastic deformation. The springs also have narrow and wide sections. The method of processing such springs is to first punch the narrow and wide sections of a thin plate, and then transport the thin plate to a bending mechanism for bending.

[0003] Patent publication number CN111451726A discloses a method for forming spring sheets for automotive electronics, including a stamping die and a center die. A strip positioning component A and a strip positioning component B are mounted on the upper end of the stamping die, and are symmetrically welded to both ends of the stamping die. A strip is placed on the end face of the stamping die between the strip positioning components A and B. This invention proposes a method for forming spring sheets for automotive electronics where the spring steel strip has a certain pre-tension force in its free state. This pre-tension force can eliminate some of the working stress during use. The method employs staggered tooling, with both sides set to an arc shape. During forming, the arc angle on both sides is made smaller than the product size. The straight section in the middle is lengthened to achieve the required size. The stress of the stainless steel spring steel strip itself after forming is utilized, and a pre-tension force is already present even when not in use, improving the stability of the forming process.

[0004] However, the above-mentioned method cannot punch the spring sheet according to the different forming requirements of the narrow and wide plate portions at both ends of the spring sheet, as well as the different forming requirements of the spring sheet length. It also cannot adjust the bending angle according to the different bending requirements of the spring sheet forming. Furthermore, the step-by-step forming efficiency is low, the workpiece has a long flow time between each process, the processing efficiency is low, continuous stamping cannot be achieved, and the production capacity cannot be met. Therefore, a forming method and forming device for automotive panoramic sunroof windshield mesh spring sheet is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a molding method and molding apparatus for a windshield mesh spring for a panoramic sunroof of an automobile, and to solve the following technical problems:

[0006] It is impossible to punch the spring according to the different forming requirements of the narrow and wide plate sections at both ends of the spring and the different forming requirements of the spring length. It is also impossible to adjust the bending angle according to the different bending requirements of the spring forming. Furthermore, the step-by-step forming efficiency is low, the workpiece has a long flow time between each process, the processing efficiency is low, continuous stamping cannot be achieved, the production capacity cannot be met, and the processing efficiency is low.

[0013] The mounting base has a first arc-shaped groove, a scale is provided on the first arc-shaped groove, and a pointer is fixedly installed on the bending plate, with the end of the pointer away from the bending plate passing through the first arc-shaped groove.

[0014] The conveying and straightening mechanism includes a conveying chamber, in which multiple conveying rollers are rotatably installed.

[0015] A first electric telescopic rod is fixedly installed on the top wall of the conveying chamber. A mounting frame is fixedly installed at the bottom of the first electric telescopic rod, and a guide roller is rotatably installed on the mounting frame.

[0016] The workbench has an installation slot. The fixing mechanism includes a toothed ring, which is rotatably installed in the installation slot.

The first toothed plates and the two second toothed plates are slidably installed on the top of the toothed ring. A second gear is rotatably installed between the first toothed plates and the toothed ring, with both sides of the second gear meshing with the first toothed plates and the toothed ring respectively.

[0017] The bottom of the workbench is provided with a second arc-shaped groove, and an operating rod is fixedly installed on the bottom of the toothed ring. The end of the operating rod away from the second arc-shaped groove passes through the second arc-shaped groove.

[0018] A molding method for a molding device for a windshield mesh spring sheet for a panoramic sunroof of an automobile includes the following steps;

[0019] Step 1: When the forming device for the spring sheet needs to be used to form the spring sheet, first place the sheet material to be processed into the conveying chamber, then start the first drive motor and the first electric telescopic rod. The first electric telescopic rod drives the mounting frame to move downward, and at the same time drives the guide roller to move downward until the bottom of the guide roller contacts the top of the sheet material. Then, the first drive motor drives the conveying roller to rotate, causing the sheet material to move between the conveying roller and the guide roller. At the same time, the conveying roller and the guide roller straighten the sheet material.

[0020] Step 2: After the sheet material is conveyed to the support platform by the conveying and straightening mechanism, the second drive motor is started to drive the bidirectional threaded rod to rotate, thereby adjusting the distance between the two moving frames and the distance between the two cutting blades. This allows for adjustment of the distance between the two cutting blades according to the sheet material length required for spring forming.

[0021] Step 3: After adjusting the distance between the two moving frames, start the second electric telescopic rod to adjust the distance between the two punching blocks, and then start the first cylinder to drive the punching blocks and the cutting blade to move downwards simultaneously.

[0022] Step 4: When the punching block and cutting blade move downwards, the fixing rod first contacts the upper surface of the plate and fixes the position of the plate. Then, as the punching block and cutting blade continue to move downwards, the spring is compressed until the punching block and cutting blade have finished punching the plate. Then, the first cylinder can drive the punching block and cutting blade to move upwards, and at the same time drive the fixing rod to move upwards.

[0023] Step 5: Start the second cylinder to move the push plate closer to the worktable, and push the punched sheet onto the worktable.

[0024] Step 6: Rotate the toothed ring in the mounting slot using the operating lever, which in turn drives the second gear to rotate. This causes the first and second toothed plates to move towards the center of the worktable until the two limit plates and two rollers contact the four sides of the plate. This completes the adjustment of the plate's position, placing it in the center of the worktable and ensuring that the bottom surface of the plate's sides is in contact with the top surface of the bent plate.

[0025] Step 7: Start the bidirectional cylinder to drive the racks on both sides to move away from each other, thereby driving the first gear to rotate. The first gear drives the bending plate to flip towards the material, thereby achieving the side bending of the material.

[0026] Step 8: When the bending plate rotates, it moves the pointer. The bending angle of the bending plate can be marked by the position of the pointer on the scale, which is convenient for bending the plate at different angles according to the needs.

[0027] Step 9: After the spring sheet is formed, the operating lever drives the limit plate and roller to reset, and then the bidirectional cylinder drives the bending plate to reset. When the second cylinder pushes the next punched sheet onto the worktable, it pushes out the previous formed spring sheet. This cycle repeats to achieve continuous forming.

[0028] The beneficial effects of this invention are:

[0029] (1) In this invention, the first drive motor drives the conveying roller to rotate, thereby driving the plate to move on the conveying roller. At the same time, the guide roller and the conveying roller cooperate to straighten the plate. The first electric telescopic rod drives the guide roller to move downward, which is beneficial to adjust the distance between the guide roller and the conveying roller according to the thickness of the plate, and facilitates the guide roller and the conveying roller to convey and straighten plates of different thicknesses.

[0030] (2) In this invention, the second drive motor drives the bidirectional threaded rod to rotate, thereby driving the two movable frames to move on the support platform, thereby adjusting the distance between the two cutting blades, which is beneficial to punching the spring sheet according to the forming requirements of different lengths by using the cutting blades;

[0031] (3) In this invention, the distance between the two punching blocks is adjusted by setting a second electric telescopic rod, which is beneficial to adjust the distance between the two punching blocks in a timely manner according to the forming requirements of the different widths of the narrow plate and the wide plate at both ends of different spring pieces;

[0032] (4) In this invention, the position of the plate is fixed at the same time as the plate is punched by the cooperation of the fixing rod and the spring, which is beneficial to the position stability of the plate during punching, avoids the plate from shifting during punching and causing poor punching effect, and further ensures the forming effect of the spring.

[0033] (5) In this invention, the first drive motor and the second cylinder are driven by the electronic cam system set in the control box, which drives the plate to step from the conveying and straightening mechanism in the X direction. Then, the plate after punching is pushed to the worktable by the push plate, thereby realizing the product stepping from the X and Y directions, reducing the flow time of the workpiece between each process, and finally realizing the continuous stamping production of the product, improving the forming and processing efficiency of the spring sheet.

[0034] (6) In this invention, the toothed ring is rotated in the mounting groove by the set operating rod, and the toothed ring drives the second gear to rotate, so that the first toothed plate and the second toothed plate drive the two limit plates and the two rollers to move towards the center of the worktable, thereby adjusting the position of the plate and placing the plate in the center of the worktable, realizing the correction of the plate position, which is beneficial to the bending of the plate and avoids the inaccurate bending position of the plate.

[0035] (7) In this invention, the first gear is rotated by a bidirectional cylinder, and the bending plate is flipped towards the material to achieve side bending of the material. The bending angle of the bending plate can be marked by the pointer on the scale, which is conducive to bending the material at different angles according to the requirements and to realizing the production of springs with different curvatures.

[0068] A molding method for a molding device for a windshield mesh spring sheet for a panoramic sunroof of an automobile includes the following steps;

[0069] Step 1: When the forming device for the spring sheet needs to be used to form the spring sheet, first place the sheet material to be processed into the conveying chamber 11, then start the first drive motor 12 and the first electric telescopic rod 14. The first electric telescopic rod 14 drives the mounting frame 15 to move downward, and at the same time drives the guide roller 16 to move downward until the bottom of the guide roller 16 contacts the top of the sheet material. Then, the first drive motor 12 drives the conveying roller 13 to rotate, causing the sheet material to move between the conveying roller 13 and the guide roller 16, and causing the sheet material to step in the X direction from the conveying straightening mechanism. At the same time, the conveying roller 13 and the guide roller 16 straighten the sheet material.

[0070] Step 2: After the sheet material is conveyed to the support table 21 by the conveying and straightening mechanism 1, the second drive motor 215 is started to drive the bidirectional threaded rod 23 to rotate, thereby adjusting the distance between the two moving frames 24, so that the distance between the two cutting blades 27 can be adjusted, which is convenient to adjust the distance between the two cutting blades 27 according to the sheet material length required for spring forming.

[0071] Step 3: After the distance between the two moving frames 24 is adjusted, start the second electric telescopic rod 210 to adjust the distance between the two punching blocks 212, and then start the first cylinder 25 to drive the punching blocks 212 and the cutting blade 27 to move downwards simultaneously.

[0072] Step 4: When the punching block 212 and the cutting blade 27 move downwards, the fixing rod 28 first contacts the upper surface of the plate and fixes the position of the plate. Then, as the punching block 212 and the cutting blade 27 continue to move downwards, the spring 29 is compressed until the punching block 212 and the cutting blade 27 have finished punching the plate. Then, the first cylinder 25 can drive the punching block 212 and the cutting blade 27 to move upwards, and at the same time drive the fixing rod 28 to move upwards.

[0073] Step 5: Start the second cylinder 213 to drive the push plate 214 to move closer to the worktable 31, and push the punched sheet onto the worktable 31 through the push plate 214.

[0074] Step 6: Drive the toothed ring 41 to rotate in the mounting groove 313 by operating lever 410, and at the same time drive the second gear 42 to rotate, so that the first toothed plate 44 and the second toothed plate 45 move towards the center of the worktable 31 until the two limit plates 46 and the two rollers 48 contact the four sides of the plate respectively, and the position of the plate is adjusted so that the plate is located in the center of the worktable 31 and the bottom surface of the side of the plate is in contact with the top surface of the bending plate 39.

[0075] Step 7: Start the bidirectional cylinder 32 to drive the rack 35 away from each other through the mounting rods 34 on both sides, thereby driving the first gear 37 to rotate. The first gear 37 drives the bending plate 39 to flip towards the material, thereby achieving the side bending of the material.

[0076] Step 8: When the bending plate 39 rotates, it drives the pointer 311 to move. The bending angle of the bending plate 39 can be marked by the position of the pointer 311 on the scale 310, which is conducive to bending the plate at different angles according to the needs.

[0077] Step 9: After the spring sheet is formed, the operating lever 410 drives the limiting plate 46 and roller 48 to reset. Then, the bidirectional cylinder 32 drives the bending plate 39 to reset. When the second cylinder 213 pushes the next punched sheet onto the worktable 31, the product can be moved from the X and Y directions. At the same time, the previously formed spring sheet is ejected. This cycle repeats to achieve continuous forming.

[0078] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

9. The forming method of the forming device for the windshield mesh spring sheet of a panoramic sunroof for automobiles according to claim 8, characterized in that, Includes the following steps; Step 1: When the forming device of the spring sheet needs to be used to form the spring sheet, first place the plate to be processed into the conveying chamber (11), then start the first drive motor (12) and the first electric telescopic rod (14), drive the mounting frame (15) to move downward through the first electric telescopic rod (14), and at the same time drive the guide roller (16) to move downward until the bottom of the guide roller (16) and the top of the plate are in contact. Then drive the conveying roller (13) to rotate through the first drive motor (12), drive the plate to move between the conveying roller (13) and the guide roller (16), and at the same time straighten the plate through the conveying roller (13) and the guide roller (16). Step 2: After the sheet material is conveyed to the support platform (21) by the conveying and straightening mechanism (1), the second drive motor (215) is started to drive the bidirectional threaded rod (23) to rotate, thereby adjusting the distance between the two moving frames (24) and the distance between the two cutting blades (27), so that the distance between the two cutting blades (27) can be adjusted according to the length of the sheet material required for the spring sheet forming. Step 3: After the distance between the two moving frames (24) is adjusted, start the second electric telescopic rod (210) to adjust the distance between the two punching blocks (212), and then start the first cylinder (25) to drive the punching blocks (212) and the cutting blade (27) to move downwards at the same time; Step 4: When the punching block (212) and the cutting blade (27) move downwards, the fixing rod (28) first contacts the upper surface of the plate and fixes the position of the plate through the fixing rod (28). Then, as the punching block (212) and the cutting blade (27) continue to move downwards, the spring (29) is compressed until the punching block (212) and the cutting blade (27) have finished punching the plate. Then, the first cylinder (25) can drive the punching block (212) and the cutting blade (27) to move upwards, and at the same time drive the fixing rod (28) to move upwards. Step 5: Start the second cylinder (213) to drive the push plate (214) to move closer to the worktable (31), and push the punched plate onto the worktable (31) through the push plate (214); Step 6: Drive the toothed ring (41) to rotate in the mounting groove (313) by operating lever (410), and drive the second gear (42) to rotate, so that the first toothed plate (44) and the second toothed plate (45) move towards the center of the worktable (31) until the two limit plates (46) and the two rollers (48) contact the four sides of the plate respectively, and the position adjustment of the plate is completed, so that the plate is located in the center of the worktable (31), and the bottom surface of the side of the plate is in contact with the top surface of the bending plate (39); Step 7: Start the bidirectional cylinder (32) to drive the rack (35) to move away from each other through the mounting rods (34) on both sides, thereby driving the first gear (37) to rotate. The first gear (37) drives the bending plate (39) to flip towards the plate, thereby achieving the side bending of the plate. Step 8: When the bending plate (39) is rotated, the pointer (311) is moved. The bending angle of the bending plate (39) can be marked by the position of the pointer (311) on the scale (310), which is conducive to bending the plate at different angles according to the needs. Step 9: After the spring sheet is formed, the limit plate (46) and roller (48) are reset by the operating lever (410), and then the bidirectional cylinder (32) drives the bending plate (39) to reset. When the second cylinder (213) pushes the next punched plate onto the worktable (31), the previous formed spring sheet is ejected. The cycle repeats to achieve continuous forming.
