Description

Technical Field

[0001] This utility model relates to the field of profile technology, and in particular to a lightweight high-strength aluminum alloy profile. Background Technology

[0002] Aluminum alloy profiles possess advantages such as lightweight, high strength, corrosion resistance, and ease of processing, and are widely used in aerospace, automotive, construction, and shipbuilding industries. Lightweight aluminum profiles help reduce the overall weight of structures, thereby reducing resource consumption and environmental pollution. This is of great significance for achieving green manufacturing and promoting sustainable development. Developing a lighter, higher-strength aluminum alloy profile has significant practical application value and market prospects.

[0003] In existing lightweight aluminum alloy profiles, reinforcement is achieved by adding ribs to the profiles during the lightweighting process. However, the simple ribs have limited reinforcement and support between the profiles, resulting in poor deformation resistance when the two-layer lightweight aluminum alloy profiles are assembled together. Therefore, we propose a lightweight high-strength aluminum alloy profile. Utility Model Content

[0004] The main objective of this invention is to provide a lightweight, high-strength aluminum alloy profile. By incorporating D-shaped grooves and U-shaped rib grooves at the profile base plate and profile backing plate respectively, weight reduction is achieved. The two sets of plates of the profile base plate and profile backing plate are welded together to form a composite base plate. Simultaneously, the two sets of composite base plates are welded and supported by a rib reinforcement mechanism to form the aluminum alloy profile plate. This invention effectively ensures the strength of the basic structure while reducing weight. Furthermore, the main support plate and secondary support plate of the rib reinforcement mechanism form a triangle through obliquely inserted rib plates. The structure features a stable support system where the bottom of the inclined reinforcing plate is inserted into the inclined groove of the main support plate, and the top of the plate abuts against the secondary support plate, enhancing the connection's strength. The reverse inclined support plate of the inclined reinforcing plate is welded to the profile lining plate with a flattened corner, forming an auxiliary support. This, together with the main and secondary support plates, constitutes a multi-directional force-bearing system. When the profile is under stress, the groove structure of the composite base plate and the three-dimensional support of the lining mechanism work together to effectively disperse stress, enabling the profile to be lightweight while possessing excellent high-strength deformation resistance, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lightweight, high-strength aluminum alloy profile includes a profile base plate, a profile liner plate, and a rib reinforcement mechanism. The rib reinforcement mechanism includes a main support plate, a secondary support plate, an inclined rib plate, and a reverse inclined support plate. The profile liner plate is welded and fixed to the double-plate surfaces of the profile base plate. An inclined rib plate is welded obliquely between the main support plate and the secondary support plate, and a reverse inclined support plate protrudes from the lower inclined surface of the central plate of the inclined rib plate. The main support plate is welded between the double-plate surfaces of the profile liner plate, and the secondary support plate is welded to the profile liner plate on one side of the main support plate. The reverse inclined support plate is welded to the profile liner plate below the secondary support plate.

[0007] Furthermore, the lower plate of the anti-sloping support plate is integrally formed with a flattened corner head, and the flattened corner head is welded to the profile liner plate.

[0008] By adopting the above technical solution, the anti-sloping support plate is firmly welded to the profile backing plate with a larger contact surface of the flattened corner head.

[0009] Furthermore, the inclined reinforcing plate has an integrally formed lifting plate portion at the upper plate head away from the anti-inclined support plate, which abuts against the inclined plate surface of the secondary support plate, and the lifting plate portion is welded to the secondary support plate at a set of plates of the profile liner plate.

[0010] By adopting the above technical solution, the inclined stiffener plate rests against the inclined surface of the secondary support plate with the lifting plate part, and then the secondary support plate and the lifting plate part can be welded together at the profile lining plate of the same group for connection.

[0011] Furthermore, a slanted groove is recessed on one side of the main support plate, and the bottom corner of the slanted reinforcing plate is inserted into the slanted groove.

[0012] By adopting the above technical solution, the main support plate can be firmly welded to the bottom corner of the inclined stiffening plate by using the oblique joint groove.

[0013] Furthermore, the back plate surface of the main support plate away from the oblique joint groove is provided with back rib grooves, and the groove depth of the back rib grooves is less than the plate thickness of the main support plate. The upper and lower plates of the main support plate are integrally formed with arc-shaped foot plates, and the main support plate is pressed between the two sets of plates of the profile liner plate by the arc-shaped foot plates and welded.

[0014] By adopting the above technical solution, a back rib groove is opened at the main support plate to form a concave rib position, which ensures the strength of the plate body while reducing weight. The two ends of the main support plate can be welded at the profile lining plate with large arc foot plates.

[0015] Furthermore, a D-shaped groove is provided through the side plate of the profile substrate, and a U-shaped rib groove is arranged on the surface of the profile liner on one side of the profile substrate.

[0016] By adopting the above technical solution, the inclined plate surface of the profile substrate is opened with D-shaped grooves to reduce weight. At the same time, the groove cavity of the D-shaped groove forms a rib groove position to ensure the strength of the plate. Similarly, the profile backing plate is opened with U-shaped rib grooves to reduce weight and also ensure the strength of the plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model achieves weight reduction by setting D-shaped grooves and U-shaped rib grooves on the profile base plate and profile liner plate respectively. The two sets of plates of the profile base plate and profile liner plate are welded together to form a combined base plate. At the same time, the two sets of combined base plates are welded together with a rib mechanism to form an aluminum alloy profile plate. This allows the aluminum alloy profile plate of this utility model to effectively ensure the strength of the basic structure while reducing weight.

[0019] Furthermore, the main support plate and the secondary support plate of the lining mechanism form a triangular stable support structure through the inclined rib plate. The bottom of the inclined rib plate is inserted into the inclined groove of the main support plate, and the top of the inclined rib plate abuts against the secondary support plate, which enhances the firmness of the connection. The reverse inclined support plate of the inclined rib plate is welded to the profile lining plate with the flattened corner head to form an auxiliary support, thus forming a multi-directional force system with the main support plate and the secondary support plate. When the profile is under stress, the rib groove structure of the composite base plate and the three-dimensional support of the lining mechanism work together to effectively disperse stress, so that the profile has excellent high strength and deformation resistance while being lightweight.

Detailed Implementation

[0025] like Figure 1-3As shown, a lightweight high-strength aluminum alloy profile includes a profile base plate 1, a profile liner plate 2, and a reinforcing rib mechanism 5. The reinforcing rib mechanism 5 includes a main support plate 6, a secondary support plate 7, an inclined reinforcing rib plate 9, and a reverse inclined support plate 10. The profile liner plate 2 is welded and fixed to the double-plate surfaces of the profile base plate 1. An inclined reinforcing rib plate 9 is obliquely welded between the main support plate 6 and the secondary support plate 7. A reverse inclined support plate 10 protrudes from the lower inclined surface of the central plate of the inclined reinforcing rib plate 9. The main support plate 6 is welded between the double-plate surfaces of the profile liner plate 2. The secondary support plate 7 is welded to the profile liner plate 2 on one side of the main support plate 6. The reverse inclined support plate 10 is welded to the profile liner plate 2 below the secondary support plate 7.

[0026] The anti-sloping support plate 10 has a flattened corner head 11 integrally formed on the lower plate body, and the flattened corner head 11 is welded to the profile liner plate 2.

[0027] By adopting the above technical solution, the anti-sloping support plate 10 is firmly welded to the profile liner plate 2 with the larger contact surface of the flattened corner head 11.

[0028] Among them, the inclined reinforcing plate 9 has an integrally formed lifting plate part 13 at the upper plate head away from the anti-inclined support plate 10, which abuts against the inclined plate surface of the secondary support plate 7, and the lifting plate part 13 is welded to the secondary support plate 7 at a set of plates of the profile liner plate 2.

[0029] By adopting the above technical solution, the inclined stiffener 9 rests against the inclined surface of the sub-support plate 7 with the lifting plate part 13, and then the sub-support plate 7 and the lifting plate part 13 can be welded together at the profile liner 2 of the same group for connection.

[0030] Among them, a slanted groove 8 is recessed on one side of the main support plate 6, and the bottom slanted rib corner of the slanted rib plate 9 is inserted into the slanted groove 8 at an angle.

[0031] By adopting the above technical solution, the main support plate 6 can be firmly welded to the bottom corner of the inclined stiffening plate 9 by using the oblique joint groove 8.

[0032] Among them, the back plate surface of the main support plate 6 away from the oblique joint groove 8 is provided with back rib grooves 12, and the groove depth of the back rib grooves 12 is less than the plate thickness of the main support plate 6. The upper and lower plates of the main support plate 6 are integrally formed with arc-shaped foot plates, and the main support plate 6 is pressed between the two sets of plates of the profile liner plate 2 with the arc-shaped foot plates.

[0033] By adopting the above technical solution, a back rib groove 12 is opened at the main support plate 6 to form a concave rib position, which ensures the strength of the plate body while reducing weight. The two ends of the main support plate 6 can be welded at the profile liner plate 2 with large arc foot plates.

[0034] Wherein, a D-shaped groove 3 is provided through the side plate surface of the profile substrate 1, and a U-shaped rib groove 4 is arranged on the surface of the profile liner 2 on one side of the profile substrate 1.

[0035] By adopting the above technical solution, the inclined plate surface of the profile substrate 1 is opened with D-shaped grooves 3 to reduce weight. At the same time, the groove cavity of the D-shaped grooves 3 forms a rib groove position to ensure the strength of the plate. Similarly, the profile liner plate 2 is opened with U-shaped rib grooves 4 to reduce weight, which can also ensure the strength of the plate.

[0036] It should be noted that this utility model is a lightweight high-strength aluminum alloy profile. After lightweight design by setting D-shaped grooves 3 and U-shaped rib grooves 4 on the profile base plate 1 and profile liner plate 2 respectively, the two sets of plates of the profile base plate 1 and profile liner plate 2 can be welded together to form a combined base plate for the aluminum alloy profile. Subsequently, a number of rib mechanisms 5 can be arranged between the profile liner plates 2 to connect and form the aluminum alloy profile. After the main support plate 6 and the secondary support plate 7 of the rib mechanism 5 are fitted and welded with inclined insert rib plates 9, the inclined insert rib plates 9 abut against the inclined surface of the secondary support plate 7 with their lifting plate parts 13. Then, the secondary support plate 7 and the lifting plate parts 13 can be welded together at the same set of profile liner plates 2 for connection. Furthermore, the main support plate 6 has large arc-shaped foot plates at both ends that can be welded to the profile liner plate 2. When this type of aluminum alloy profile plate is under stress, the combined base plate composed of the profile base plate 1 and the profile liner plate 2 is reinforced by internal rib grooves after being stressed, making the combined base plate less prone to deformation under stress. At the same time, the main support plate 6 supports the rib mechanism 5 between the combined base plates. The secondary support plate 7 is connected to the main support plate 6 and the profile liner plate 2 by welding with the inclined rib plate 9. The inclined rib plate 9 has a reverse inclined support plate 10 pressing on the profile liner plate 2 below the secondary support plate 7 to form an auxiliary lightweight support structure, effectively ensuring that the aluminum alloy profile plate of this utility model is not easily deformed after being stressed and has good stress resistance and deformation strength.
