Description

Technical Field

[0001] This invention relates to the field of bending device technology, specifically to a multi-point synchronous bending device for an electro-galvanized steel plate control panel frame and its usage method. Background Technology

[0002] The electro-galvanized steel plate center console frame is the core load-bearing structural component of the automotive center console. It is made from electro-galvanized steel plate through stamping, welding and other processes. The electro-galvanized layer forms anti-corrosion protection and improves the corrosion resistance of the steel plate. At the same time, the structural strength and rigidity of the plate support the installation and fixation of various electrical appliances, trim parts and functional components of the center console. It also ensures the structural stability of the center console under vehicle driving and collision conditions. It is a core basic component of automotive interior that takes into account protection, support and structural reliability.

[0003] The multi-point synchronous bending device for the electro-galvanized steel plate center console frame is a special forming equipment designed for the structural characteristics and bending processing requirements of the electro-galvanized steel plate center console frame. It can realize the synchronous and precise force application and forming of multiple bending parts in the frame processing, effectively match the material characteristics of the electro-galvanized steel plate, avoid coating damage and plate deformation, ensure the dimensional accuracy, structural strength and coating integrity of the bending parts of the center console frame, improve the overall processing efficiency and forming quality of the frame, and adapt to the process requirements of its mass production.

[0004] Due to the unique adhesion characteristics of the coating, electro-galvanized steel sheets are susceptible to stress during the synchronous bending process of the center console frame. If the sheet is not properly fixed, displacement and stretching can easily occur, leading to coating cracking and peeling. This directly affects the overall structural strength and reliability of the electro-galvanized steel center console frame. Therefore, a multi-point synchronous bending device and its application method for electro-galvanized steel center console frames are proposed to address these issues. Summary of the Invention

A second fixing die is fixedly connected to the rear end of the anti-detachment slider.

[0008] As a further optimization of the present invention, the driving component includes a frame, the bottom end of the frame is fixedly connected to the top end of the base plate, the rear end of the frame is fixedly connected to a slide cylinder, and through holes are provided on the inner sides of both the frame and the slide cylinder.

[0009] As a further optimization of the present invention, the slide cylinder is slidably connected to a slide column, the inner side of the frame is fixedly connected to the cylinder body of the electric hydraulic cylinder, the front end of the slide column is fixedly connected to the rear end of the push plate, and the end of the piston rod of the electric hydraulic cylinder is fixedly connected to the rear end of the push plate.

[0010] As a further optimization of the present invention, a double-threaded rod is rotatably connected to the inner side of the first bending die, a limit hole is opened on the inner side of the first bending die, the upper and lower ends of the double-threaded rod extend out of the outer side of the first bending die, and the outer side of the double-threaded rod is threadedly connected to the threaded hole of the positioning component.

[0011] As a further optimization of the present invention, the threaded hole is formed inside the push block, a guide rod is slidably connected inside the limiting hole, the guide rod is fixedly connected to one end of the push block, and a gripper is fixedly connected to the front end of the push block.

[0012] As a further optimization of the present invention, the gripper is located at the front end of the first bending die, and a galvanized frame blank is clamped on one side of the gripper.

[0013] As a further optimization of the present invention, the rear end of the second bending die is fixedly connected to a wheel frame, and a roller is rotatably connected to the inner side of the wheel frame. Both the wheel frame and the roller are embedded in the built-in groove, which is opened at the front end of the push plate, and the rear end of the roller is in contact with the rear end of the built-in groove.

[0014] As a further optimization of the present invention, the end of the first spring away from the crossbar is fixedly connected to the inside of the rail groove, and the crossbar is slidably connected to the inside of the rail groove through the rail block.

[0015] As a further optimization of the present invention, the base is fixedly connected to the top of the base plate, the first fixing mold and the first bending mold are aligned front to back, and the second fixing mold and the second bending mold are aligned front to back.

[0016] Multi-point synchronous bending device for electro-galvanized steel plate center console frame and its usage method;

[0017] Step 1: When positioning the galvanized frame blank, place the galvanized frame blank at the front end of the first bending die, and align the middle of the galvanized frame blank with the middle of the first bending die. By operating the double threaded rod, the double threaded rod is rotatably connected inside the first bending die. Since the double threaded rod is threadedly connected to the threaded hole, the rotation of the double threaded rod will simultaneously drive the upper and lower positioning components to move. According to the setting of the double threaded rod, the positioning components will move towards the galvanized frame blank at the same time. The push block drives the guide rod to move, and the guide rod slides inside the limiting hole. The threaded hole will simultaneously drive the jaws to move. The upper jaw and the lower jaw will simultaneously squeeze the upper and lower ends of the galvanized frame blank. The front end of the galvanized frame blank protrudes from the front end of the jaws, so that the center of the galvanized frame blank is aligned with the center of the first bending die, thus completing the positioning of the galvanized frame blank.

[0018] Step 2: When bending the galvanized frame blank, the electric hydraulic cylinder is activated to drive the push plate forward. The push plate drives the sliding column to move. The sliding column slides inside the frame body and the slide cylinder. The push plate drives the first bending die and the galvanized frame blank to move forward simultaneously. When the rear end of the first fixed die contacts the front end of the galvanized frame blank, and the rear end of the second fixed die contacts the front end of the galvanized frame blank, the middle part of the galvanized frame blank is bent by the cooperation of the first bending die and the first fixed die. The two ends of the galvanized frame blank are bent by the cooperation of the second fixed die and the second bending die. The two ends of the galvanized frame blank are displaced due to bending. Through friction, the second bending die and the second fixed die at both ends are displaced. The second bending die drives the crossbar to move. The crossbar slides inside the rail groove through the rail block. The crossbar presses against the first spring. The second fixed die drives the anti-detachment slider to move. The anti-detachment slider slides inside the anti-detachment groove. The anti-detachment slider presses against the second spring.

[0019] Step 3: During the bending process, the movement of the second bending die will drive the wheel frame and roller to move simultaneously. The wheel frame and roller slide inside the built-in groove. Since the roller is in contact with the rear end of the built-in groove, the roller rotates due to friction. The roller rotates inside the wheel frame.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the device can achieve precise positioning of the galvanized frame blank by setting the first bending mold, double threaded rod and gripper, ensuring that the middle part of the galvanized frame blank and the middle part of the first bending mold, and the center of the galvanized frame blank and the center of the first bending mold can be precisely aligned, providing a stable guarantee for the subsequent bending process of the galvanized frame blank, effectively preventing the galvanized frame blank from shifting or misaligning during the bending process, ensuring the accuracy of the bending process, and thus helping to improve the overall processing quality and reliability of the electro-galvanized steel plate center console frame;

[0022] 2. In this invention, by setting a first bending mold, a first fixing mold and a second bending mold, the device can achieve precise bending of the middle and both ends of the galvanized frame blank, effectively preventing the coating from cracking and peeling due to stress tension during the bending process of the galvanized frame blank, while ensuring the stability of the bending process, and ensuring the overall structural strength and reliability of the final electro-galvanized steel plate central control panel frame.

[0023] 3. In this invention, the second bending die, wheel frame, and built-in groove effectively reduce the friction force when the second bending die moves, provide effective support for the second bending die, prevent the second bending die from moving backward when subjected to reaction force, ensure the safety of the crossbar and the second bending die, and further improve the stability of the bending process of the galvanized frame blank, thus helping to ensure the bending processing quality and the structural reliability of the electro-galvanized steel plate central control panel frame.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0043] Please see Figures 1-10 The present invention provides a technical solution:

[0044] A multi-point synchronous bending device for an electro-galvanized steel plate center console frame and its usage method include a base plate 1, a drive assembly 2, a bending assembly 3 installed at the front end of the drive assembly 2, a positioning assembly 4 installed inside the bending assembly 3, a movable assembly 5 installed inside the positioning assembly 4, and a fixing assembly 6 installed at the upper end of the base plate 1. The bending assembly 3 includes a push plate 31, a first bending mold 32 fixedly connected to the front end of the push plate 31, and a rail groove 36 opened inside the push plate 31. The movable assembly 5 includes a first spring 51, a crossbar 52 fixedly connected to one side of the first spring 51, a rail block 53 fixedly connected to the top of the crossbar 52, and a second bending mold 54 fixedly connected to the other side of the crossbar 52. The fixing assembly 6 includes a base 61, a first fixing mold 62 fixedly connected to the inner side of the base 61, an anti-detachment groove 63 opened inside the base 61, second springs 64 fixedly connected to both the left and right sides of the first fixing mold 62, an anti-detachment slider 65 fixedly connected to one side of the second spring 64, and a second fixing mold 66 fixedly connected to the rear end of the anti-detachment slider 65.

[0045] As a further implementation of this solution, the drive assembly 2 includes a frame 21, the bottom of which is fixedly connected to the top of the base plate 1, and a slide cylinder 22 is fixedly connected to the rear end of the frame 21. Both the frame 21 and the slide cylinder 22 have through holes on their inner sides. Through the above settings, a stable sliding installation base is provided for the slide column 23, ensuring the guidance of the slide column 23 during the sliding process, indirectly improving the stability of the push plate 31 movement, and thus providing support for the smoothness of the bending process of the galvanized blank 7, helping to ensure the bending accuracy.

[0046] As a further implementation of this solution, a sliding column 23 is slidably connected to the inner side of the sliding cylinder 22, and the inner side of the frame 21 is fixedly connected to the cylinder body of the electric hydraulic cylinder 24. The front end of the sliding column 23 is fixedly connected to the rear end of the push plate 31, and the end of the piston rod of the electric hydraulic cylinder 24 is fixedly connected to the rear end of the push plate 31. Through the above settings, the push plate 31 and subsequent connecting parts can be moved forward smoothly, ensuring that the force applied during the bending of the galvanized frame blank 7 is stable and the displacement is accurate, avoiding the bending deviation and coating damage of the galvanized frame blank 7 due to unstable movement, and ensuring the bending processing quality.

[0047] As a further implementation of this solution, a double-threaded rod 33 is rotatably connected to the inner side of the first bending die 32. A limit hole 34 is opened on the inner side of the first bending die 32. The upper and lower ends of the double-threaded rod 33 extend out of the outer side of the first bending die 32. The outer side of the double-threaded rod 33 is threadedly connected to the threaded hole 41 of the positioning component 4. Through the above settings, a core structural support is provided for the precise positioning of the galvanized frame blank 7. The rotation of the double-threaded rod 33 can drive the related components to move synchronously, ensuring that the center and middle part of the galvanized frame blank 7 are precisely aligned with the center of the first bending die 32, laying a stable foundation for subsequent bending processing and preventing bending misalignment.

[0048] As a further implementation of this solution, the threaded hole 41 is opened inside the push block 42, and the guide rod 43 is slidably connected inside the limiting hole 34. The guide rod 43 is fixedly connected to one end of the push block 42, and the front end of the push block 42 is fixedly connected to the gripper 44. Through the above settings, the movement of the push block 42 can be precisely limited, ensuring that the gripper 44 can uniformly squeeze the upper and lower ends of the galvanized frame blank 7, thereby achieving precise positioning of the galvanized frame blank 7, improving the stability of the positioning operation, and avoiding positioning offset from affecting the subsequent bending quality.

[0049] As a further implementation of this solution, the gripper 44 is located at the front end of the first bending die 32, and the galvanized frame blank 7 is clamped on one side of the gripper 44. Through the above setting, the galvanized frame blank 7 is firmly clamped at the upper and lower ends, realizing the precise positioning of the galvanized frame blank 7, ensuring that the galvanized frame blank 7 is precisely aligned with the center and middle part of the first bending die 32, preventing the galvanized frame blank 7 from shifting or misaligning during the bending process, ensuring the accuracy of the bending process, and helping to improve the processing quality of the center console frame.

[0050] As a further implementation of this solution, a wheel frame 55 is fixedly connected to the rear end of the second bending die 54, and a roller 56 is rotatably connected to the inner side of the wheel frame 55. Both the wheel frame 55 and the roller 56 are embedded in the inner groove 35, which is opened at the front end of the push plate 31. The rear end of the roller 56 fits against the rear end of the inner groove 35. Through the above arrangement, the friction force when the second bending die 54 moves can be effectively reduced, a stable support can be formed for the second bending die 54, and the second bending die 54 can be prevented from moving backward under the reaction force, ensuring the safety of the crossbar 52 and the second bending die 54. At the same time, the stability of the bending process of the galvanized blank 7 is improved, and the coating damage is avoided during the bending process.

[0051] As a further implementation of this solution, the end of the first spring 51 away from the crossbar 52 is fixedly connected to the inside of the rail groove 36, and the crossbar 52 is slidably connected to the inside of the rail groove 36 through the rail block 53. Through the above arrangement, stable guidance and limit are provided for the movement of the crossbar 52, ensuring that the crossbar 52 can move synchronously and smoothly with the second bending die 54 and form uniform compression on the first spring 51, avoiding the impact of the crossbar 52's movement and offset on the bending accuracy of both ends of the galvanized frame blank 7, thereby ensuring the integrity of the coating and the reliability of the skeleton structure;

[0052] As a further implementation of this solution, the bottom end of the base 61 is fixedly connected to the top end of the base plate 1. The first fixed mold 62 is aligned with the first bending mold 32, and the second fixed mold 66 is aligned with the second bending mold 54. Through the above settings, it is ensured that the first fixed mold 62 can accurately cooperate with the first bending mold 32 to achieve bending in the middle of the galvanized frame blank 7, and the second fixed mold 66 can accurately cooperate with the second bending mold 54 to achieve bending at both ends of the galvanized frame blank 7. This ensures the accuracy of multi-point synchronous bending of the galvanized frame blank 7, avoids problems such as bending misalignment and coating cracking, and ensures the structural strength and reliability of the center console frame.

[0053] Workflow: When positioning the galvanized blank 7, place it at the front end of the first bending die 32, aligning the middle of the blank with the middle of the first bending die 32. Operate the double-threaded rod 33, which is rotatably connected inside the first bending die 32. Since the double-threaded rod 33 is threaded into the threaded hole 41, its rotation simultaneously moves the upper and lower positioning components 4. Based on the thread configuration of the double-threaded rod 33, the positioning components 4 move towards the galvanized blank 7. The push block 42 moves the guide rod 43, guiding... The rod 43 slides inside the limiting hole 34, which serves to limit the movement of the push block 42. The threaded hole 41 will simultaneously drive the jaw 44 to move. The upper jaw 44 and the lower jaw 44 will simultaneously squeeze the upper and lower ends of the galvanized frame blank 7. The front end of the galvanized frame blank 7 protrudes from the front end of the jaw 44, so that the center of the galvanized frame blank 7 is aligned with the center of the first bending die 32, thereby achieving the positioning effect of the galvanized frame blank 7. This positioning operation not only achieves the positioning effect of the middle part of the galvanized frame blank 7, but also provides stability for the bending of the galvanized frame blank 7, preventing the galvanized frame blank 7 from being misaligned during bending due to displacement.

[0054] When bending the galvanized billet 7, the electric hydraulic cylinder 24 is activated to move the push plate 31 forward. The push plate 31 moves the sliding column 23, which slides inside the frame 21 and the slide cylinder 22, improving the stability of the push plate 31's movement. The push plate 31 moves the first bending die 32 and the galvanized billet 7 forward simultaneously. When the rear end of the first fixed die 62 contacts the front end of the galvanized billet 7, and the rear end of the second fixed die 66 contacts the front end of the galvanized billet 7, the cooperation of the first bending die 32 and the first fixed die 62 achieves the effect of bending the middle of the galvanized billet 7. The cooperation of the second fixed die 66 and the second bending die 54 achieves the effect of bending both ends of the galvanized billet 7. At this time, the galvanized billet 7... The two ends will be displaced due to bending. The friction force of the galvanized frame blank 7 will simultaneously drive the second bending mold 54 and the second fixing mold 66 at both ends to move. At this time, the second bending mold 54 drives the crossbar 52 to move. The crossbar 52 slides in the rail groove 36 through the rail block 53. The crossbar 52 presses against the first spring 51. The second fixing mold 66 drives the anti-detachment slider 65 to move. The anti-detachment slider 65 slides in the anti-detachment groove 63. The anti-detachment slider 65 presses against the second spring 64. The above principle can prevent the coating from cracking and peeling due to the stress stretching during the bending process of the galvanized frame blank 7, and ensure the overall structural strength and reliability of the final electro-galvanized steel plate center console frame.

[0055] During the bending process, the movement of the second bending die 54 drives the wheel frame 55 and roller 56 to move simultaneously. The wheel frame 55 and roller 56 slide inside the built-in groove 35. Since the roller 56 is in contact with the rear end of the built-in groove 35, the roller 56 rotates due to friction. The rotation of the roller 56 inside the wheel frame 55 not only reduces the friction when the second bending die 54 moves, but also, through the support of the wheel frame 55 and roller 56, ensures that the second bending die 54 will not move backward under the action of reaction force when it extrudes the galvanized blank 7. This ensures the safety of the crossbar 52 and the second bending die 54 and improves the stability of bending the galvanized blank 7.

Push block (42) drives guide rod (43) to move. Guide rod (43) slides inside limit hole (34). Thread hole (41) will drive jaw (44) to move at the same time. Upper jaw (44) and lower jaw (44) will simultaneously squeeze the upper and lower ends of galvanized frame blank (7). The front end of galvanized frame blank (7) protrudes from the front end of jaw (44), so that the center of galvanized frame blank (7) is aligned with the center of first bending die (32) front and back, thus completing the positioning of galvanized frame blank (7). Step 2: When bending the galvanized frame blank (7), start the electric hydraulic cylinder (24) to drive the push plate (31) to move forward. The push plate (31) drives the slide column (23) to move. The slide column (23) slides inside the frame body (21) and the slide cylinder (22). The push plate (31) drives the first bending die (32) and the galvanized frame blank (7) to move forward at the same time. When the rear end of the first fixed die (62) contacts the front end of the galvanized frame blank (7), and the rear end of the second fixed die (66) contacts the front end of the galvanized frame blank (7), the middle part of the galvanized frame blank (7) is bent by the cooperation of the first bending die (32) and the first fixed die (62). (66) The galvanized frame blank (7) is bent at both ends by the cooperation of the second bending die (54). The two ends of the galvanized frame blank (7) are displaced due to the bending. The friction force simultaneously drives the second bending die (54) and the second fixed die (66) at both ends to move. The second bending die (54) drives the crossbar (52) to move. The crossbar (52) slides in the rail groove (36) through the rail block (53). The crossbar (52) squeezes the first spring (51). The second fixed die (66) drives the anti-detachment slider (65) to move. The anti-detachment slider (65) slides in the anti-detachment groove (63). The anti-detachment slider (65) squeezes the second spring (64). Step 3: During the bending process, when the second bending die (54) moves, it will drive the wheel frame (55) and roller (56) to move simultaneously. The wheel frame (55) and roller (56) slide inside the built-in groove (35). Since the roller (56) is in contact with the rear end of the built-in groove (35), the roller (56) will rotate due to friction. The roller (56) rotates inside the wheel frame (55).
