Description

Technical Field

[0001] This invention relates to the technical field of automotive crossbeam processing, and in particular to a forming device for lightweight automotive support crossbeams. Background Technology

[0002] As the global automotive industry moves towards energy conservation and environmental protection, lightweighting has become a core technological competitive advantage for major automakers. By reducing the overall vehicle weight, fuel consumption and emissions can be effectively reduced. For new energy vehicles, lightweighting is one of the key paths to improve driving range. Against this technological backdrop, the design of thin-walled and high-strength structural components has become the mainstream trend.

[0003] As a key safety component in the vehicle body structure, the lightweight support beam is typically installed inside the door or on the side of the vehicle. Its main function is to transmit and absorb the impact force during side collisions, while also maintaining the rigidity of the door panel during opening and closing. Bending the sheet metal is an essential core process in the manufacturing of the support beam. Currently, the industry commonly uses hydraulic bending machines with specialized bending dies. However, the upper and lower die angles on traditional bending machines are usually fixed, corresponding to a specific bending angle. In actual production, because different vehicle models or different parts of the same model have varying bending angle requirements for the support beam, operators have to frequently stop the machine to change the entire set of bending dies. This die-changing operation is not only time-consuming and labor-intensive, severely impacting production efficiency, but frequent disassembly and assembly can also lead to a decrease in die positioning accuracy, thus affecting the quality of the formed workpiece. Furthermore, traditional bending equipment cannot continuously adjust the bending angle according to process requirements during processing, making it difficult to adapt to the rapid response requirements of flexible production lines. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a lightweight automotive support beam forming device, the specific technical solution of which is as follows: The present invention provides a lightweight support beam forming device for automobiles, comprising a fixed platform for supporting a sheet metal plate, a movable platform for bending the sheet metal plate, and a pressing body for pressing the bending position of the sheet metal plate. The fixed platform and the movable platform are connected to each other, and the movable platform is driven by several hydraulic cylinders. Several fixing slots are provided on both the fixed platform end face and the movable platform end face, and the fixing slots on the fixed platform and the movable platform are arranged opposite to each other. The fixed platform and the movable platform are rotatably connected by several connecting units. Each connecting unit includes a connecting frame one, a connecting frame two, and a hinge column for rotatably connecting the connecting frame one and the connecting frame two. The connecting frame one and the connecting frame two are arranged crosswise. One end of the connecting frame one and one end of the connecting frame two are respectively rotatably installed in the corresponding fixing slots on the fixed platform and the movable platform. The other end of the connecting frame one and the other end of the connecting frame two are provided with sliding columns. The sliding columns on the connecting frame one and the connecting frame two are respectively located in the corresponding fixing slots on the movable platform and the fixed platform. The end of the sliding column is provided with a guide groove, and the sliding column is slidably disposed in the guide groove.

[0005] Furthermore, one end of the guide groove is rotatably mounted on the inner wall of the corresponding fixed groove via an auxiliary shaft.

[0006] Furthermore, an arc arm is provided at the other end of the guide groove. The arc arm is coaxially arranged with the auxiliary shaft. Several arc platforms are provided at the bottom of the fixed platform and the bottom of the movable platform, corresponding to the fixed groove. The end of the arc arm extends out of the fixed groove and is slidably connected to the corresponding arc platform. Several slots are provided on the arc platform. A locking plate is slidably provided at the end of the arc arm. The locking plate is used in conjunction with the slots. The arc arm and the locking plate are connected by an elastic body.

[0007] Furthermore, several floating platforms are slidably arranged on both the fixed platform working surface and the movable platform working surface, and the floating platforms are provided with a restoring elastic force through an elastic body.

[0008] Furthermore, the pressing body includes two core columns arranged coaxially, one end of each core column is provided with a rotating shaft, and the core column can be offset on the working surface of the fixed table through the rotating shaft. The other ends of the two core columns are respectively provided with inserts and holes that cooperate with each other. Several strips are arranged on the outer wall of the core column along the circumference of the core column, and the distance between the strips and the core column is adjustable.

[0009] Furthermore, the strips are slidably arranged relative to the core column via several inclined platforms, and an adjusting sleeve is slidably sleeved on the core column. The adjusting sleeve is rotatably connected to each of the strips via a connecting arm, and the adjusting sleeve is fastened to the core column via a set screw.

[0010] Furthermore, a number of long sliding openings are provided on the fixed platform, a movable plate is slidably arranged in the long sliding openings, a long opening is provided on the movable plate, and a number of threaded grooves are provided on the inner sidewall of the long opening. A positioning plate for positioning the sheet material is provided on the movable plate, and the positioning plate is fixed on the movable plate by bolts and corresponding threaded grooves.

[0011] Furthermore, a movable frame is slidably arranged at the bottom of the movable platform, the movable end of the hydraulic cylinder is connected to the movable frame, and the movable frame and the movable platform are connected by an elastic body. Several movable plates are connected by movable frames two. Inclined platforms two are provided on one side wall of the movable frame and on the side wall of the movable frame two. A side pusher is slidably arranged between the two inclined platforms two. The sliding direction between the side pusher and the inclined platform two is inclined. The side pusher is slidably arranged on the movable platform. The sliding direction of the movable frame one is parallel to the sliding direction of the movable frame two. The sliding direction of the side pusher on the movable platform is perpendicular to the sliding direction of the movable frame one.

[0012] The beneficial effects of this invention are as follows: By employing a folding method using a fixed table and a movable table, the sheet metal is bent. This, combined with the pressing body's compression of the bent area, allows the sheet metal to be processed into a specified angle. This method is simple in structure and easy to operate. Different bending angles can be achieved by directly controlling the folding angle between the fixed and movable tables, resulting in higher controllability of the bending angle. Unlike traditional methods that can only process specific angles and require frequent mold changes, this method utilizes a connecting unit to connect the fixed and movable tables. In their natural state, the fixed and movable tables abut against each other, while during processing, they separate and avoid each other. This allows for precise control of the sheet metal processing in conjunction with the pressing body. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 8 As shown, a lightweight support beam forming device for automobiles according to the present invention includes a fixed platform 1 for supporting the plate, a movable platform 2 for bending the plate, and a pressing body 3 for pressing the bending position of the plate. The fixed platform 1 and the movable platform 2 are connected to each other, and the movable platform 2 is pushed by several hydraulic cylinders 4. Several fixing slots are provided on both the end face of the fixed platform 1 and the end face of the movable platform 2. The fixing slots on the fixed platform 1 and the fixing slots on the movable platform 2 are arranged opposite to each other. The fixed platform 1 and the movable platform 2 are rotatably connected by several connecting units 5. The connecting unit 5 includes a connecting frame 1 6, a connecting frame 2 7, and a hinge column 8 for rotatably connecting the connecting frame 1 6 and the connecting frame 2 7. The connecting frame 1 6 and the connecting frame 2 7 are arranged crosswise. One end of the connecting frame 1 6 and one end of the connecting frame 2 7 are respectively rotatably installed in the corresponding fixing slots on the fixed platform 1 and the movable platform 2. The other end of the connecting frame 1 6 and the other end of the connecting frame 2 7 are provided with sliding columns 9. The sliding columns 9 on the connecting frame 1 6 and the sliding columns 9 on the connecting frame 2 7 are respectively located in the corresponding fixing slots on the movable platform 2 and the fixed platform 1. The end of the sliding column 9 is provided with a guide groove 10, and the sliding column 9 can slide in the guide groove 10.

[0019] Specifically, both the fixed table 1 and the movable table 2 are horizontally arranged, with the fixed table 1 fixed and the movable table 2 movable relative to the fixed table 1. This changes the angle between the upper working surfaces of the fixed table 1 and the upper working surfaces of the movable table 2. When the sheet is placed on the fixed table 1 and the movable table 2, the movable table 2 can bend the sheet by moving relative to the fixed table 1. The pressing body 3 is located above the joint between the fixed table 1 and the movable table 2, and is located on the upper surface of the sheet. When the movable table 2 moves and bends the sheet, the pressing body 3 can press the bent position of the sheet, thereby performing the bending process. The hydraulic cylinder 4 provides power for the movement of the movable table 2. At the same time, depending on the extension length of the hydraulic cylinder 4 and the rotation angle of the movable table 2 relative to the fixed table 1, the sheet can be bent into different angles. That is, the bending process and the specific bending angle of the sheet can be directly limited by the movement angle of the movable table 2. This processing mode of the sheet is more direct and efficient, and the processing angle can be adjusted arbitrarily.

[0020] Several fixing slots are provided on both the end face of the fixed platform 1 facing the movable platform 2 and the end face of the movable platform 2 facing the fixed platform 1. The fixing slots on the fixed platform 1 and the fixing slots on the movable platform 2 are connected to each other to form a sealed chamber. This sealed chamber is mainly used to install the connecting unit 5. That is, initially, the fixed platform 1 and the movable platform 2 can form a docking mode without any gaps between them, and this mode will not hinder the normal movement of the movable platform 2. The connecting frame 1 6 and the connecting frame 2 7 in the connecting unit 5 are distributed in a cross pattern. At the cross position, the connecting frame 1 6 and the connecting frame 2 7 can be rotatably connected by the hinge post 8. The hinge post 8 can be located in the middle of the connecting frame 1 6 or the connecting frame 2 7 or biased towards either end. At the same time, the position of the hinge post 8 on the connecting frame 1 6 must correspond to the position on the connecting frame 2 7. Since one end of the connecting frame 1 6 and one end of the connecting frame 2 7 are respectively rotatably installed in the corresponding two fixing slots. Therefore, the end of connecting frame 6, the end of connecting frame 7, and the hinge column 8 can form a triangle. The other ends of connecting frame 6 and connecting frame 7 can guide the deformation movement of the triangle. When the cylinder 4 pushes the movable table 2 to move, the movable table 2 can drive the connecting unit 5 to move. The connecting frame 6 and connecting frame 7 in the connecting unit 5 rotate relative to each other through the hinge column 8, and the sliding column 9 slides in the corresponding guide groove 10. At this time, the angle of the included angle on the triangle where the hinge column 8 is located increases, and the movable table 2 and the fixed table 1 gradually separate from each other. At the same time, the guide of the sliding column 9 and the guide groove 10 to the connecting frame 6 and connecting frame 7 will cause the movable table 2 to gradually flip upward, so that the movable table 2 can normally push the plate to bend. When bending, the movement trajectory of the movable table 2 toward the corner of the pressing body 3 corresponds to the pressing body 3, so that the plate is bent on the pressing body 3.

[0021] In actual use, a base or mounting platform can be set at the bottom of the fixed platform 1, and the fixed end of the hydraulic cylinder 4 can be rotatably mounted on the base or mounting platform.

[0022] By using a fixed platform 1 and a movable platform 2 to fold the sheet metal, and then using a pressing body 3 to press the sheet metal at the folded position, the sheet metal can be processed into a specified angle. This method has a simple structure and is easy to operate. It can directly control the folding angle between the fixed platform 1 and the movable platform 2 to process the sheet metal at different bending angles. The bending angle is more controllable, unlike the traditional method which can only process a specific angle and requires frequent mold changes. The connecting unit 5 connects the fixed platform 1 and the movable platform 2. In the natural state, the fixed platform 1 and the movable platform 2 can abut against each other, while during processing, the fixed platform 1 and the movable platform 2 can avoid each other and separate, so that they can cooperate with the pressing body 3 to process the sheet metal, effectively improving the precision control of sheet metal processing.

[0023] Furthermore, one end of the guide groove 10 is rotatably mounted on the inner wall of the corresponding fixed groove via an auxiliary shaft 11.

[0024] When the guide groove 10 rotates in the fixed groove via the auxiliary shaft 11, the guide groove 10 has different tilt angles, which can guide the slide column 9 in different directions. The cooperation between the slide column 9 and the guide groove 10 guides the connecting frame 6 and the connecting frame 7. Therefore, by adjusting the tilt angle of the guide groove 10, the movement trajectory of the movable table 2 toward the corner of the pressing body 3 can be adjusted, which makes it convenient to process the bending position of the sheet metal into rounded corners of different curvatures.

[0025] Furthermore, an arc arm 12 is provided at the other end of the guide groove 10. The arc arm 12 is coaxially arranged with the auxiliary shaft 11. Several arc platforms 13 are provided at the bottom of the fixed platform 1 and the bottom of the movable platform 2, corresponding to the fixed groove. The end of the arc arm 12 extends out of the fixed groove and slides with the corresponding arc platform 13. Several slots are provided on the arc platform 13. A locking plate 14 is slidably provided at the end of the arc arm 12. The locking plate 14 is used in conjunction with the slots, and the arc arm 12 and the locking plate 14 are connected by an elastic body 15.

[0026] The arc platform 13 is coaxially arranged with the auxiliary shaft 11. Several slots are arranged on the arc surface of the arc platform 13. The elastic force of the elastic body 15 on the locking plate 14 can push the locking plate 14 into the corresponding slot. At this time, the slot and the locking plate 14 lock the position of the arc arm 12, thereby limiting the position of the guide groove 10. When it is necessary to adjust the tilt angle of the guide groove 10, the locking plate 14 can be moved from the corresponding slot and the arc arm 12 can be moved by the locking plate 14. Then the locking plate 14 can be locked into other corresponding slots.

[0027] Furthermore, several floating platforms 16 are slidably arranged on both the working surface of the fixed platform 1 and the working surface of the movable platform 2. The floating platforms 16 are provided with a restoring elastic force through the elastic body 2 17.

[0028] When the fixed platform 1 and the movable platform 2 move relative to each other and bend the board, the bottom surface of the board will be displaced from the upper surface of the fixed platform 1 and the upper surface of the movable platform 2. This will cause friction between the board and the fixed platform 1 and the movable platform 2, and interfere with the normal deformation of the board. To solve the above problem, the board can be placed on the floating platform 16. When the board is bent, the board can push the floating platform 16 to move on the corresponding fixed platform 1 or movable platform 2, thereby reducing friction and improving the smoothness of the board deformation.

[0029] Furthermore, the pressing body 3 includes two coaxially arranged core columns 18. One end of the core column 18 is provided with a rotating shaft 23, and the core column 18 can be offset on the working surface of the fixed table 1 through the rotating shaft 23. The other ends of the two core columns 18 are respectively provided with inserts and holes that cooperate with each other. Several strips 19 are arranged on the outer wall of the core column 18 along the circumference of the core column 18, and the distance between the strips 19 and the core column 18 can be adjusted.

[0030] The rotating shaft 23 is vertically rotatable on the base, and the core column 18 is horizontally located above the fixed platform 1. The core column 18 is aligned with the fixed platform 1 and the movable platform 2. The two core columns 18 are coaxially connected by inserts and holes, and the inserts can move within the corresponding core column 18 by electromagnetic push or other means. In use, the two core columns 18 are in a mating state, the plate is located between the core column 18 and the fixed platform 1, the movable platform 2 moves and pushes the plate to bend, and several strips 19 on the core column 18 squeeze the plate, so that the plate bends smoothly. After the plate is processed, the insert can move within the corresponding core column 18 and disengage from the hole at the end of the other core column 18. At this time, the two core columns 18 separate from each other, and the two rotating shafts 23 rotate synchronously, so that the two core columns 18 can rotate off the fixed platform 1 on the working surface of the fixed platform 1. At this time, the processed plate can be directly removed, avoiding the core column 18 from obstructing the movement of the plate when the bending angle is too large.

[0031] By utilizing the adjustable position function of several strips 19 on the core column 18, the diameter of the circle containing the strips 19 can be adjusted, thereby facilitating the adjustment of the curvature of the bending position of the plate. At the same time, it can be coordinated with the movement trajectory of the movable table 2 when the angle of the guide groove 10 is adjusted.

[0032] It should be noted that when processing plates of different thicknesses, the rotating shaft 23 can be moved in the vertical direction.

[0033] Furthermore, the slats 19 are slidably inclined relative to the core column 18 via several inclined platforms 20, and an adjusting sleeve 21 is slidably sleeved on the core column 18. The adjusting sleeve 21 is rotatably connected to each slat 19 via a connecting arm 22, and the adjusting sleeve 21 is fastened to the core column 18 via a set screw.

[0034] When adjusting the position of the adjusting sleeve 21 on the core post 18, the adjusting sleeve 21 can push several strips 19 to slide on the corresponding inclined platform 20 through several connecting arms 22. The distance between the strips 19 and the core post 18 changes, thereby changing the curvature of the bending position of the plate. After the position of the strips 19 is adjusted, the adjusting sleeve 21 can be locked on the core post 18 by the set screw.

[0035] Furthermore, a number of long sliding openings 24 are provided on the fixed platform 1, and a movable plate 25 is slidably arranged in the long sliding openings 24. A long opening 26 is provided on the movable plate 25, and a number of threaded grooves are provided on the inner side wall of the long opening 26. A positioning plate 27 for positioning the plate is provided on the movable plate 25. The positioning plate 27 is fixed to the movable plate 25 by bolts 28 and corresponding threaded grooves.

[0036] The positioning plate 27 can contact the end of the plate, thereby initially positioning the plate in the processing position and improving processing accuracy. Each threaded groove in the long opening 26 can be used with the bolt 28. Therefore, when it is necessary to change the position of the positioning plate 27, simply pass the bolt 28 through the positioning plate 27 and screw it into the different threaded grooves. When the movable table 2 moves and bends the plate, in order to avoid deformation of the plate and damage to the positioning plate 27, the positioning plate 27 needs to avoid the plate after completing its positioning work. This can be achieved by moving the movable plate 25 a small distance within the long sliding opening 24.

[0037] It should be noted that a fixing structure can be added to the floating platform 16 on the fixed platform 1 to facilitate the fixing of the positioned plate, or the plate can be pressed by the worker; the movement of the movable plate 25 within the long sliding opening 24 can be accomplished by other pushing structures.

[0038] Furthermore, a movable frame 29 is slidably installed at the bottom of the movable platform 2, and the movable end of the hydraulic cylinder 4 is connected to the movable frame 29. The movable frame 29 and the movable platform 2 are connected by an elastic body 30. Several movable plates 25 are connected by movable frame 2 31. Inclined platform 2 32 is provided on the side wall of movable frame 1 29 and the side wall of movable frame 2 31. A side pusher 33 is slidably arranged between the two inclined platforms 2 32, and the sliding direction between the side pusher 33 and the inclined platform 2 32 is inclined. The side pusher 33 is slidably arranged on the movable platform 2. The sliding direction of movable frame 1 29 is parallel to the sliding direction of movable frame 2 31, and the sliding direction of the side pusher 33 on the movable platform 2 is perpendicular to the sliding direction of movable frame 1 29.

[0039] The elastic body 30 provides elastic thrust to the movable frame 29. In its natural state, the elastic body 30 is in an elastically deformed state. When the plate needs to be processed, the hydraulic cylinder 4 extends. At this time, the hydraulic cylinder 4 and the elastic body 30 jointly push the movable frame 29 to move on the movable table 2. The movable frame 29 uses its inclined platform 2 32 to push the side pusher 33 to move. The side pusher 33 then uses the inclined platform 2 32 on the movable frame 2 31 to push the movable frame 2 31 to move, thereby making the movable frame 29 and the movable frame 2 31 move synchronously in opposite directions. The movable frame 2 31 pushes the movable frame 29 to move in opposite directions. The movable plate 25 moves within the long slide 24, thereby removing the positioning plate 27 that has completed the positioning work at the beginning of the processing. When the deformation of the elastic body 30 is large, or when the movable plate 25 moves to one end of the long slide 24, the movable plate 25 stops moving. At this time, the force provided by the hydraulic cylinder 4 to the movable frame 29 is directly transmitted to the movable table 2 and pushes the movable table 2 to move relative to the fixed table 1. The movable table 2 begins to bend the plate. In this way, a single hydraulic cylinder 4 can provide power for the positioning plate 27 to avoid and for the movable table 2 to move.

[0040] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
