Description

Technical Field

[0001] The invention relates to the technical field of automobile longitudinal beam stamping, in particular to a high-precision stamping forming process of an automobile right longitudinal beam based on lateral calibration. Background Art

[0002] The car longitudinal beam is one of the most important load-bearing components in a car and a key part of the frame. It mainly bears the weight of the car body and withstands the impact of the road. If there is a problem or damage to the right longitudinal beam of the car, it may affect the vehicle's handling, safety and stability. Damage to the longitudinal beam may cause the vehicle to become unstable, shake and other problems during driving, affecting the driving experience. Damage to the longitudinal beam may affect the structural integrity of the vehicle and increase the risk of injury in an accident.

[0003] However, the traditional automobile longitudinal beam forming device lacks the calibration transmission function. When transmitting the metal sheet, it cannot effectively drive the sheet to be accurately placed in the center of the mold, resulting in deviations during the stamping process, affecting the stamping quality of the product. In addition, it is difficult to continuously detect defects on the sheet surface during the feeding process, causing potential problems in the quality inspection of the longitudinal beam after stamping.

[0004] For example, if there are defects in the sheet metal during feeding (such as dents, cracks, etc.), and they cannot be detected and adjusted in time, these defects may further expand during the stamping process, and eventually lead to quality problems in the longitudinal beam. Therefore, it is necessary to update and improve the above conditions to ensure that the sheet metal can be accurately positioned during the transmission and stamping process to avoid deviations and the occurrence of unqualified products. Summary of the invention

[0005] The purpose of the present invention is to provide a high-precision stamping process for a right longitudinal beam of an automobile based on lateral calibration, so as to solve the problem in the prior art of lacking calibration transmission and continuous plate defect detection functions, which easily leads to quality problems in the longitudinal beam after forming.

[0033] A visual inspection machine 20 is fixedly installed on the top of the operating table 1. It should be noted that the visual inspection machine 20 is an existing device, which is used to detect whether there are defects on the surface of the plate to be stamped. The top of the side walls of the operating table 1 and the stamping workbench 18 are fixedly connected with an alignment frame 21, and the interior of the alignment frame 21 is slidably connected with a calibration plate 22. The outer side of the alignment frame 21 is fixedly connected with an electric push rod 3 15, and the output end of the electric push rod 3 15 is fixedly connected to the side wall of the calibration plate 22.

[0034] The turning assembly 5 includes a plurality of support plates 501 and a plurality of connecting rails 502 . The support plates 501 and the connecting rails 502 are fixedly connected to the top and the bottom of the shaft sleeve 4 , respectively. The support plates 501 are arranged in the corresponding guide grooves 2 .

[0035] Two partitions are fixedly connected to the top of the inner wall of the operating table 1, and electric push cylinder 1 503 and electric push cylinder 2 504 are fixedly installed on the side walls of the partitions. The output ends of electric push cylinder 1 503 and electric push cylinder 2 504 are fixedly connected with drive blocks 505, and the drive blocks 505 are slidably connected in the corresponding connecting rails 502. Multiple groups of installation grooves are opened on one side of the support plate 501, and suction cups 506 are fixedly installed in the installation grooves. The suction cups 506 can realize the functions of automatic adsorption and automatic desorption of the plate. A baffle 507 is fixedly connected to the bottom of the side wall of the support plate 501.

[0036] During the specific setting, the plate is placed on the top of the operating table 1, and the suction cup 506 adsorbs and fixes the surface of the plate, and then the electric push cylinder 1 503 and the electric push cylinder 2 504 cooperate with the connecting track 502 through the corresponding driving block 505, so as to realize the synchronous rotation of the shaft sleeve 4 on the outside of the rotating shaft 1 301 and the rotating shaft 2 302. During the rotation, the shaft sleeve 4 drives the correspondingly connected support plate 501 on the top to rotate. When the top support plate 501 of the shaft sleeve 4 on the outside of the rotating shaft 1 301 drives the plate to turn over synchronously, the visual inspection machine 20 performs the first image acquisition on the surface of the plate. When the top support plate 501 of the shaft sleeve 4 on the outside of the rotating shaft 1 301 drives the plate to approach the top support plate 501 of the shaft sleeve 4 on the outside of the rotating shaft 2 302, the suction cup 506 set on the side wall of the support plate 501 adsorbs and fixes the other side of the plate, so as to realize the turning over of the plate. At this time, the visual inspection machine 20 performs the second image acquisition on the plate, and then analyzes the two image acquisitions. The specific plate surface damage analysis process is as follows:

[0037] A photo of the plate surface is obtained through the camera of the visual inspection machine 20, the collected plate image is enlarged into a pixel grid image, and the collected pixel grid image is marked as an initial pixel grid image, and the pixel grid of the initial pixel grid image is marked as n, where n is a positive integer greater than 1, and image processing is performed on the initial pixel grid image to obtain the pixel grid grayscale value of the initial pixel grid image, and the pixel grid grayscale value is marked as HDm, and the pixel grid grayscale value threshold HDmax is obtained through the storage module, and the pixel grid grayscale value HDm is compared with the pixel grid grayscale value threshold HDmax. When the pixel grid grayscale value HDm is lower than the pixel grid grayscale value threshold HDmax, the number is marked as T1, and the number of pixel grid grayscale values ​​HDm not lower than the pixel grid grayscale value threshold HDmax is marked as T2;

[0038] The pixel grid image overlap rate CH is obtained through the formula CH=Ti / n, and the pixel grid image overlap rate threshold CHmax is obtained through the storage module. The pixel grid image overlap rate CH is compared with CHmax. When the pixel grid image overlap rate CH is lower than CHmax, it means that there is no defect on the surface of the plate. When the pixel grid image overlap rate CH is higher than CHmax, it means that there is a defect on the surface of the plate.

[0039] Embodiment 2: Electric push rods 8 are fixedly installed at the four corners of the bottom inner wall of frame 7, and the material dividing assembly includes a support rack 601 and a support rack 602. Support rack 602 is fixedly installed on the top of support rack 601, and the output end of the electric push rod 8 is fixedly connected to the bottom of support rack 601.

[0040] A cover shell 603 is fixedly installed on the top of the support rack 1 601 and the support rack 2 602. A through slot 604 is opened on the top of the cover shell 603. A threaded rod 1 605 is movably connected to the inside of the through slot 604 through a bearing. A slider 606 is slidably connected to the through slot 604. A push plate 607 is fixed to the top of the slider 606 by bolts. A motor for driving the threaded rod 1 605 to rotate is fixedly connected to the outer wall of the cover shell 603.

[0041] The upper surfaces of the support frame 1 601 and its top cover shell 603 are penetrated with limited slots 9 on both sides, the inner side wall of the frame 7 is fixedly connected with a bracket 10, the top of the bracket 10 is movably connected with a rotating rod 11 through a bearing, the outer side of the rotating rod 11 is sleeved and fixed with a sleeve 12, the bottom of the side wall of the rotating rod 11 is fixed with a driving rail 13 by electric welding, the top of the bracket 10 is fixedly connected with an electric push rod 2 14, the output end of the electric push rod 2 14 is fixedly connected with a convex block, the convex block is slidably connected in the driving groove provided at the bottom of the driving rail 13, the side wall of the sleeve 12 is fixed with a support 16 by spot welding, the support 16 is movably connected with an abutting roller 17 through a bearing, the top of the bottom plate 100 is fixedly installed with a stamping workbench 18, and the top of the stamping workbench 18 is installed with a lifting stamping table 19. It should be noted here that the function of the stamping workbench 18 is to place the plate, and the lifting stamping table 19 is used for stamping the plate placed on the top of the stamping workbench 18.

[0042] In the specific setting, when the plate has surface defects after inspection, the electric push rod 1 8 drives the support rack 1 601 and the support rack 2 602 to rise synchronously until the support rack 1 601 is at the same height as the operating table 1, and the top plate 23 on the top of the operating table 1 pushes the plate into the top of the cover 603 on the top of the support rack 2 602, and then the push plate 607 pushes the plate to the designated storage area

[0043] When the plate has no surface defects after inspection, the electric push rod 18 drives the support rack 1 601 and the support rack 2 602 to rise synchronously until the top cover 603 of the support rack 1 601 is consistent with the height of the operating table 1. The top plate 23 on the top of the operating table 1 pushes the plate to the top of the top cover 603 of the support rack 1 601 under the action of the threaded rod 2, and the support rack 1 601 drives the plate to descend until the contact roller 17 passes through the limit groove 9 provided in the support rack 1 601 and its top cover 603. At this time, the support rack 1 601 and its top cover 603 are consistent with the height of the stamping workbench 18;

[0044] Then, the electric push rod 14 is started, and the electric push rod 14 pushes the driving rail 13 to deflect. The driving rail 13 drives the rotating rod 11 and the sleeve 12 to deflect synchronously. During the deflection process, the sleeve 12 drives the abutment roller 17 to deflect through the support 16. The abutment rollers 17 on both sides of the plate simultaneously perform laterally calibrate the edge of the plate. Then, the threaded rod 605 drives the push plate 607 to move, and the push plate 607 pushes the plate to the top of the stamping workbench 18. During this process, the abutment roller 17 rotates in a circle under the action of the sliding of the plate, and the position of the plate to be stamped is further lateralized by the calibration plate 22 arranged on the side wall of the stamping workbench 18. After the position is calibrated, the punching head at the bottom of the lifting stamping table 19 punches the plate into the right longitudinal beam of the car. By performing multiple lateral position calibrations on the plate, precise stamping of the plate is achieved.
