Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, specifically a sheet metal transition support frame. Background Technology

[0002] Automotive body panels refer to the spatially shaped surface or internal parts made of thin metal sheets that cover the engine, chassis, and form the cab and body. They can be divided into three categories according to function and location: external body panels, internal body panels, and frame body panels. They are both decorative parts and enclosed, thin-shell load-bearing components. They generally include front and rear bumpers, doors, front fenders, hoods, and trunk lids. They differ from general stamped parts in terms of process design, mold processing, equipment selection, and quality control (dimensional tolerances, shape accuracy, part rigidity, surface quality). Automotive body panels are an important component of automobiles.

[0003] The production process of automotive exterior body panels involves uncoiling steel coils, leveling with a leveling machine, and stamping with a press to achieve the final shape. A certain distance is usually reserved between the leveling machine and the press to prevent interference between the press's three-axis crossbar and the leveling machine when clamping the material. Therefore, to ensure that the leveled sheet metal smoothly enters the press's worktable for stamping, a transition support rack needs to be installed within the reserved space between the leveling machine and the press to support and guide the sheet metal.

[0004] Traditional material support racks only provide support and guidance, and cannot be universally applicable to sheet metal of different sizes, resulting in poor versatility. Furthermore, due to the movement trajectory of the clamping crossbar, they typically only support the middle of the sheet metal, which can easily cause the sides of the sheet metal to sag and bend, leading to stamping quality problems. Utility Model Content

[0005] To address the problem that traditional sheet metal support racks are not versatile and typically only support the middle of the sheet metal, which can easily cause the sides of the sheet metal to sag and bend, resulting in a decrease in stamping quality, this utility model provides a sheet metal transition support rack.

[0006] This utility model is achieved through the following technical solution:

[0007] A sheet material transition support frame includes a first support frame, with several rows of vertical flow strip fixing brackets installed in the middle of the first support frame, and a row of flow strip flipping brackets that can be rotated outwards installed on both sides of the first support frame. Each row of flow strip fixing brackets and each row of flow strip flipping brackets are equipped with a flow strip that can support and guide the sheet material at the upper end. Several flipping cylinders are rotatably installed on the first support frame, and the telescopic ends of the flipping cylinders are rotatably connected to the flow strip flipping brackets.

[0008] A further improvement of this utility model is that the first support frame is positioned and installed with perforated fixing blocks on both sides, and the cylinder body of the tilting cylinder is provided with a central trunnion that is rotatably connected to the perforated fixing blocks.

[0009] A further improvement of this utility model is that a fixed hinge seat is positioned and installed on the first support frame, and a flip hinge seat that is rotatably connected to the fixed hinge seat is connected and installed at the lower end of the flow bar flip bracket; a cylinder connecting seat that is rotatably connected to the telescopic end of the flip cylinder is connected and installed on one side of the upper end of the flow bar flip bracket.

[0010] A further improvement of this utility model is that the flow bar includes a horizontal longitudinal roller mounting rod, on which several rollers are rotatably mounted.

[0011] A further improvement of this invention is that the roller is a bearing structure.

[0012] A further improvement of this utility model is that the roller mounting rod adopts an aluminum profile structure, and its upper part has a slot for embedding the roller, with connecting shafts for connecting and installing the roller passing through both sides of the slot.

[0013] A further improvement of this utility model is that the connecting shaft is made of bolts, and one end of it is screwed on by a nut.

[0014] A further improvement of this utility model is that the outer ring of the roller is provided with a rubber layer.

[0015] A further improvement of this utility model is that it also includes a second support frame; a reduction motor and a reversing gearbox connected to the reduction motor are installed in the middle of the second support frame, and screw jacks that support and connect to the first support frame are installed at its four corners respectively. The reversing gearbox is connected to the screw jacks through a drive shaft.

[0016] A further improvement of this utility model is that the geared motor is connected to the reversing gearbox via a flexible coupling.

[0017] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0018] This sheet metal transition support frame is installed between the leveling machine and the press. It supports the sheet metal via flow bars, providing temporary storage and preventing interference between the press's three-axis crossbar and the leveling machine when clamping the sheet. The flexible flipping brackets on both sides of the flow bars reliably support sheet metal of varying widths, preventing wider sheets from sagging or bending. When the clamping crossbar clamps the sheet, the retracting cylinder controls the flow bar flipping brackets to rotate outward, thus avoiding obstruction of the clamping crossbar's movement and preventing damage from impacts. The overall structure is simple, combining reliable sheet metal support with obstruction of the clamping crossbar, making it highly practical. Attached Figure Description

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] like Figure 1-5As shown, this utility model discloses a sheet material transition support frame, including a first support frame 2. Several rows (front-back direction) of vertical flow strip fixing brackets 18 are installed in the middle of the first support frame 2. A row (front-back direction) of flow strip flipping brackets 14 that can be flipped outward are rotatably installed on both sides of the first support frame 2. Each row (front-back direction) of flow strip fixing bracket 18 and each row of flow strip flipping brackets 14 is equipped with a flow strip 1 that can support and guide the sheet material (front-back). Several flipping cylinders 7 are rotatably installed on the first support frame 2. The telescopic ends of the flipping cylinders 7 are rotatably connected to the flow strip flipping brackets 14.

[0028] This device is installed between the leveling machine and the press. The flow bar 1 supports the sheet metal, providing temporary storage and preventing interference between the press's three-axis crossbar and the leveling machine when clamping the sheet. Furthermore, the flexible rotation of the flow bar flipping brackets 14 on both sides allows for reliable support of sheet metal of varying widths, preventing wider sheets from sagging or bending. When the clamping crossbar clamps the sheet, the retracting cylinder 7 controls the flow bar flipping brackets 14 to rotate outward, thus avoiding obstruction of the clamping crossbar's movement and preventing damage from impacts. The overall structure is simple, combining reliable sheet metal support with obstruction of the clamping crossbar, making it highly practical.

[0029] There are three fixed brackets 18 for each column of flow bar and three flipping brackets 14 for each column of flow bar.

[0030] The first support frame 2 has perforated fixing blocks 11 positioned on both sides, and the tilting cylinder 7 has a central trunnion rotatably connected to the perforated fixing blocks 11. A fixed hinge seat 17 is positioned on the first support frame 2, and a tilting hinge seat 16, rotatably connected to the fixed hinge seat 17, is connected to the lower end of the flow bar tilting bracket 14. A cylinder connecting seat 15, rotatably connected to the telescopic end of the tilting cylinder 7, is connected to one side of the upper end of the flow bar tilting bracket 14. This allows the tilting cylinder 7 to flexibly tilt the flow bar tilting bracket 14.

[0031] like Figure 4 As shown, the flow bar 1 includes a horizontal longitudinal (front-to-back) roller mounting rod 20, on which several rollers 19 are rotatably mounted. The rollers 19 are bearing structures to ensure smooth support and guidance of the sheet metal. The roller mounting rod 20 is made of aluminum profile, with a slot at its upper part for mounting the rollers 19. Connecting shafts for connecting and mounting the rollers 19 are threaded through both sides of the slot. The connecting shafts are bolted, with one end screwed on by a nut. The lower part of the roller mounting rod 20 is connected to the upper end of the flow bar flipping bracket 14 and the upper end of the flow bar fixing bracket 18 via T-bolts. The flow bar 1 has a simple overall structure, is easy to implement, and the rollers 19 and roller mounting rod 20 are easy to assemble, disassemble, and replace.

[0032] The outer ring of roller 19 is equipped with a rubber layer. This provides support for the sheet material, increases static friction, prevents slippage, and avoids wear on the sheet material.

[0033] This sheet material transition support also includes a second support frame 4; a reduction motor 10 and a reversing gearbox 9 connected to the reduction motor 10 are installed in the middle of the second support frame 4, and screw jacks 5, which support the first support frame 2, are installed at its four corners. The reversing gearbox 9 is connected to the screw jacks 5 via a drive shaft 6. The reduction motor 10 drives the first support frame 2 to rise and fall through the reversing gearbox 9 and the four screw jacks, which can realize the flexibility of sheet material support and realize the convenience of use.

[0034] The geared motor 10 is connected to the reversing gearbox 9 via a flexible coupling 3. This allows for tolerance of deviations and ensures the accuracy of power transmission.

[0035] The screw jack 5 is equipped with an encoder 8 on one side for precise control of the lifting stroke of the screw jack 5.

[0036] The flow bar flipping bracket 14 is equipped with a limit switch 12 to limit the clamping crossbar and achieve interlocking. When the flow bar flipping bracket 14 does not flip outward, the clamping crossbar acts on the limit switch 12 and stops, avoiding collision and improving the safety of use.

[0037] The second support frame 4 is equipped with a switch fixing plate 13, which has upper and lower limit switches to limit the upper and lower limit positions of the first support frame 2 to prevent damage to the screw jack 5.

[0038] This sheet metal transition support frame is installed between the leveling machine and the press. It supports the sheet metal via flow bars 1, providing temporary storage and preventing interference between the press's three-axis crossbar and the leveling machine when clamping the sheet. Furthermore, the flexible flipping supports 14 on both sides of the flow bars reliably support sheet metal of varying widths, preventing wider sheets from sagging or bending. When the clamping crossbar clamps the sheet, the retracting cylinder 7 controls the flow bar flipping supports 14 to rotate outward, thus avoiding obstruction of the clamping crossbar's movement and preventing damage from impacts. The overall structure is simple, combining reliable sheet metal support with obstruction of the clamping crossbar, making it highly practical.
