[0002] Stamping is the most common and largest-scale component production process in the automotive manufacturing industry. Taking the cab as an example, especially for commercial vehicles, hundreds or even thousands of large and small body panels need to go through multiple stamping, welding, and painting processes to complete. For automakers with a complex range of vehicle models, the shapes and types of large body panel stamping parts required to construct different cabs also vary. These stamping parts are generally stored using customized workstation equipment, leading to an increased investment in workstation equipment and significant pressure on inventory and logistics management.

[0029] like Figure 1-6 As shown, a universal storage device for large covered stamped parts for commercial vehicles includes a U-shaped frame base and a limiting mechanism.

[0030] Multiple limiting mechanisms are respectively set at different positions on the U-shaped frame base; different types of stamped parts are set on the U-shaped frame base, and the limiting mechanisms dynamically adjust the limits;

[0031] The limiting mechanism includes a movable side limiting mechanism, a flexible side limiting mechanism, a fixed bottom limiting mechanism, a movable bottom limiting mechanism, and a flip-type side limiting mechanism; the movable bottom limiting mechanism and the fixed bottom limiting mechanism are located above the bottom of the U-shaped frame base, the movable side limiting mechanism and the flexible side limiting mechanism are located on the left side of the U-shaped frame base and face the center; the flip-type side limiting mechanism is located on the right side of the U-shaped frame base and faces the center.

[0032] The movable side-limiting mechanism includes a side U-shaped beam 6, a fixed shaft 7, and flipping rods 8. The side U-shaped beam 6 is located on the left side of the U-shaped frame seat, and the fixed shaft 7 is mounted on the side U-shaped beam 6. Several flipping rods 8 are equidistantly arranged and rotatably connected to the fixed shaft 7. Preferably, both ends of the side U-shaped beam 6 are connected to two columns 1 on the left side. The flipping rods 8 are made of steel bars and are connected to the fixed shaft 7 through sleeves. Rotating the flipping rods 8 towards the center of the device increases or decreases the limiting effect by flipping them. When removing the part, the limiting effect can be removed by manually flipping the flipping rods 8. The length of the flipping rods 8 is less than the depth of the side profile of the stamped part, and their spacing is greater than the maximum width when several identical stamped parts are stored at the same time.

[0033] The flexible side limiting mechanism includes a second side U-shaped beam 9, an elastic device 10, a first flip-back limiting device 12, and a first flip-locking device 11. The second side U-shaped beam 9 is rotatably mounted on the left side of the U-shaped frame seat, and the first flip-locking device 11 and the first flip-back limiting device 12 are provided on the second side U-shaped beam 9. One end of the elastic device 10 is connected to one side of the U-shaped frame seat, and the other end is connected to the second side U-shaped beam 9. Preferably, both ends of the second side U-shaped beam 9 are connected to the two columns 1 on the left side through movable shafts. The elastic device 10 is an air spring, two in number, respectively set between the left column 1 and the second side U-shaped beam 9, which provides pressure for the flipping of the second side U-shaped beam 9. The first flip-back limiting device 12 is a rigid block, set on the column 1 and located on the second side U-shaped beam, which prevents the second side U-shaped beam 9 from flipping downwards. The first flip-locking device 11 is a combination of steel nails, locking nuts, and positioning holes on the column 1 to fix the second side U-shaped beam 9. Of course, a handle 13 can also be installed on the side U-beam 2 9; when removing the part, use the handle to flip the side U-beam 2 9 upwards to detach it from the side of the stamped part, and at the same time insert the steel nail into the locking nut and the positioning hole on the column 1 to fix the side U-beam 2 9; after the above actions are completed, the stamped parts can be removed one by one. In the working state, the flexible side limiting mechanism must be exactly against the side of the stamped part, and at this time the air spring stroke must not reach the upper limit.

[0034] The fixed bottom limiting mechanism includes an inverted U-shaped beam 14, which is positioned above the bottom of the U-shaped frame base. Several limiting blocks 16 are mounted on the inverted U-shaped beam 14, and these limiting blocks 16 are equidistantly spaced. Preferably, both ends of the inverted U-shaped beam 14 are welded to the base plate 2, and the limiting blocks are made of steel, serving to support and separate the stamped parts.

[0035] The movable bottom limiting mechanism includes a fixed base 19, a movable shaft 18, a buckle 17, and an inverted U-shaped beam 15. The fixed base 19 is located above the bottom of the U-shaped frame base. The inverted U-shaped beam 15 is connected to the fixed base 19 via the movable shaft 18 and is limited by the buckle 17. Several limiting blocks 16 are provided on the inverted U-shaped beam 15. The limiting blocks 16 are equidistantly arranged. Preferably, both ends of the inverted U-shaped beam 14 are connected to the two fixed bases 19 via the movable shaft 18. The buckle 17 is a triangular buckle, which switches the inverted U-shaped beam 15 between vertical and inverted states. Similarly, the limiting blocks are made of steel blocks, thus realizing the bottom limiting function for different types of stamped parts.

[0036] The flip-type side limiting mechanism includes an L-shaped beam 20, a buffer pad, a flip-back limiting device 21, and a flip-locking device 22. The L-shaped beam 20 is rotatably mounted on the right side of the U-shaped frame seat, and the flip-locking device 22 and the flip-back limiting device 21 are mounted on the U-shaped frame seat. A buffer pad is provided at the end of the L-shaped beam 20. Preferably, the two ends of the L-shaped beam 20 are of unequal length, which can adjust the distance between the stamped part and the frame. The L-shaped beam 20 is positioned between the two columns 1 on the right side and flips towards the center of the device. The flip-back limiting device 21 is a limiting block, which is positioned on the outside of the two columns 1 on the right side to prevent the L-shaped beam 20 from flipping outward. The flip-locking device 22 is a detachable T-shaped rod structure, which can be used to lock the L-shaped beam 20 in the flip position. The buffer pad is made of polyurethane strip. Different types of stamped parts can be limited by switching different flipping modes. Several toothed grooves are arranged on the polyurethane strip. The depth of the toothed grooves is greater than the depth of the flow channel of the stamped parts, and the width of the polyurethane grooves is greater than the maximum width when several stamped parts of the same type are stored at the same time.

[0037] The U-shaped frame base includes a base plate 2, columns 1 and base 3; at least four bases 3 are provided with columns 1, and at least the bottom of the columns 1 are provided with base plates 2.

[0038] The U-shaped frame base is also equipped with crane hooks 4. Preferably, there are four crane hooks 4, which are located on the outside of the column 1.

[0039] The U-shaped frame base is also provided with forklift holes 5. Preferably, the forklift holes 5 are located at the bottom of the base plate 2.

[0040] Taking the side panel as an example:

[0041] When storing the Type A side panel, the movable bottom limiting mechanism of the device is in an upright state, and together with the fixed bottom limiting mechanism, it abuts against the bottom of several side panels. The flipping locking device of the flipping side limiting mechanism is opened, and the flipping side limiting mechanism flips towards the center of the device, abutting against the right end of the side panel. The flexible limiting mechanism achieves flexible contact and pressing between the flexible limiting end and the left side of the side panel through the thrust of the air spring, and the movable side limiting mechanism abuts against the left side of the side panel.

[0042] When storing the Type B side panel, the movable bottom limiting mechanism of the device is in an upright state, and together with the fixed bottom limiting mechanism, it abuts against the bottom of several side panels. The flip-type limiting mechanism's flip locking device is closed, the flip-type side limiting mechanism abuts against the right end of the side panel, the flexible limiting mechanism achieves flexible contact and pressing between the flexible limiting end and the left side of the side panel through the air spring thrust, and the movable side limiting mechanism abuts against the left side of the side panel.

[0043] When storing the C-shaped side panel, the movable bottom limiting mechanism of the device is in a folded-down state, and together with the fixed bottom limiting mechanism, it abuts against the bottom of several side panels. The flip-type limiting mechanism's flip locking device is closed, the flip-type side limiting mechanism abuts against the right end of the side panel, the flexible limiting mechanism achieves flexible contact and pressing between the flexible limiting end and the left side of the side panel through the air spring thrust, and the movable side limiting mechanism abuts against the left side of the side panel.

[0044] This device enables the universal storage of different types of side panel panels by switching between different combinations of limiting mechanisms. Simultaneously, these various limiting mechanisms ensure the stability and safety of the device regardless of whether it is under empty or fully loaded transport conditions.
