Description

Technical Field

[0001] This utility model relates to the field of aluminum profile production technology, specifically a straightening device for aluminum profile production. Background Technology

[0002] Aluminum profiles refer to aluminum materials formed by extruding aluminum alloys. They are widely used in construction, transportation, machinery, electronics and other fields. Aluminum profiles have advantages such as being lightweight, high-strength, corrosion-resistant and easy to process. Common aluminum profiles include aluminum alloy frames, aluminum alloy doors and windows, and aluminum alloy railings. The production process of aluminum profiles usually includes steps such as melting and casting, extrusion, heat treatment and surface treatment. Depending on different application requirements, aluminum profiles can undergo surface treatments such as anodizing, electrophoretic coating, and spraying to improve their corrosion resistance and aesthetics.

[0003] CN220111982U discloses a straightening device for aluminum profile production, including a conveyor belt and a support column. A straightening chamber is fixedly connected to the top of the support column. The conveyor belt passes through the interior of the straightening chamber. An anti-deformation limiting component is installed on the straightening chamber. An electric heating plate is fixedly connected to the inner wall of the straightening chamber. A hydraulic cylinder is fixedly connected to the upper surface of the straightening chamber, and a straightening pressure plate is fixedly connected to the output end of the hydraulic cylinder. This invention uses a drive motor to drive a bidirectional threaded screw to rotate. The rotation of the bidirectional threaded screw causes the limiting adjustment frames on both sides to move closer to the sides of the aluminum profile, ultimately limiting the sides of the aluminum profile. During the straightening process, this prevents the aluminum profile from deforming to both sides, ensuring the quality and effect of the straightening process.

[0004] The aforementioned patent addresses the shortcomings of existing straightening devices where the straightening top plate straightens aluminum profiles as they pass over the conveyor belt. Because the aluminum profiles are subjected to unidirectional pressure during straightening, they are prone to deformation on both sides due to the pressure, ultimately resulting in poor processing quality. This application provides another solution to address the problems raised in the aforementioned patent. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a straightening device for aluminum profile production, which has the advantage of good straightening effect. It solves the problem that in existing straightening devices, the straightening top plate straightens the aluminum profile while it is passing over the conveyor belt. Since the aluminum profile is subjected to unidirectional pressure at this time, the aluminum profile is easily deformed on both sides due to the pressure during the straightening operation, which ultimately leads to poor processing effect of the aluminum profile.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a straightening device for aluminum profile production, comprising a base plate and a rectangular frame and a support plate fixedly installed on the surface of the base plate, wherein a straightening mechanism is provided between the base plate and the rectangular frame;

[0007] The straightening mechanism includes a first hydraulic cylinder fixedly mounted on one side surface of a support plate, a push plate fixedly mounted on the end of the first hydraulic cylinder away from the support plate, a second hydraulic cylinder fixedly mounted on the upper surface of the inner cavity of the rectangular frame, a U-shaped connecting frame fixedly mounted on the bottom of the second hydraulic cylinder, a first connecting shaft rotatably mounted on the inner side of the U-shaped connecting frame, a second connecting shaft rotatably mounted on the inner side of the rectangular frame, straightening rollers fixedly mounted on the surfaces of both the first and second connecting shafts, and a tapered groove formed on the surface of the straightening rollers. A first replacement component is provided between the second hydraulic cylinder and the U-shaped connecting frame, and a second replacement component is provided between the second connecting shaft and the rectangular frame.

[0008] Furthermore, the first connecting shaft and the second connecting shaft correspond to each other, and the straightening roller on the first connecting shaft corresponds to the straightening roller on the corresponding second connecting shaft.

[0009] Furthermore, the first replacement component includes a connecting column fixedly installed at the bottom of the second hydraulic cylinder. The connecting column has an annular groove on its surface and a retaining ring fixedly installed on its surface. The U-shaped connecting frame has a round hole on its surface and a strip cavity inside the U-shaped connecting frame. A spring is fixedly installed inside the strip cavity. A round rod located inside the strip cavity is fixedly installed at one end of the spring. A connecting plate extending through to the outer surface of the U-shaped connecting frame is fixedly installed on the surface of the round rod. A retaining plate is fixedly installed at the bottom of the connecting plate, and a retaining groove is formed on the surface of the retaining plate.

[0010] Furthermore, the surface of the U-shaped connecting frame is provided with a strip-shaped hole that communicates with the strip-shaped cavity, and the connecting plate is located inside the strip-shaped hole.

[0011] Furthermore, the diameter of the circular hole is adapted to the diameter of the connecting post.

[0012] Furthermore, the second replacement component includes a horizontal groove formed on the opposite side surface of the rectangular frame and a vertical groove connected to the horizontal groove. The diameter of the second connecting shaft is adapted to the inner width of the horizontal groove and the vertical groove. Four baffles are fixedly installed on the surface of the second connecting shaft, with each pair of baffles forming a group and respectively close to both ends of the second connecting shaft.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The straightening device for aluminum profile production has two sets of corresponding straightening rollers on a rectangular frame. Conical grooves are opened on the surface of the straightening rollers. When in use, the aluminum profile can be placed in the conical grooves, and the two sets of straightening rollers are used to apply pressure to straighten the aluminum profile. At the same time, the internal slope of the conical grooves can prevent deformation on both sides of the aluminum profile, which greatly improves the straightening effect of the aluminum profile.

[0015] 2. The straightening device for aluminum profile production has a first replacement component between the second hydraulic cylinder and the U-shaped connecting frame, and a second replacement component between the second connecting shaft and the rectangular frame. During use, the straightening roller can be replaced so that the straightening roller can be adapted to different aluminum profiles. Attached Figure Description

Straightening rollers 11 are fixedly installed on the surfaces of both the first connecting shaft 8 and the second connecting shaft 9. A conical groove 12 is formed on the surface of the straightening roller 11.

[0026] A first replacement assembly is provided between the second hydraulic cylinder 6 and the U-shaped connecting frame 7. A first connecting shaft 8 and a second connecting shaft 9 correspond to each other. A straightening roller 11 on the first connecting shaft 8 corresponds to a straightening roller 11 on the corresponding second connecting shaft 9. The first replacement assembly includes a connecting post 13 fixedly installed at the bottom of the second hydraulic cylinder 6. An annular groove 14 is formed on the surface of the connecting post 13. A retaining ring 15 is fixedly installed on the surface of the connecting post 13.

A spring 18 is fixedly installed on the part, and a round rod 19 located in the strip cavity 17 is fixedly installed on one end of the spring 18. A connecting plate 20 extending through to the outer surface of the U-shaped connecting frame 7 is fixedly installed on the surface of the round rod 19. A clamping plate 21 is fixedly installed at the bottom of the connecting plate 20. A clamping groove 22 is opened on the surface of the clamping plate 21. A strip hole 23 communicating with the strip cavity 17 is opened on the surface of the U-shaped connecting frame 7. The connecting plate 20 is located in the strip hole 23, which facilitates the movement of the connecting plate 20 on the U-shaped connecting frame 7.

[0028] The working principle of the above embodiments is as follows:

[0029] In use, the aluminum profile is placed on the straightening roller 11 on the second connecting shaft 9, so that the aluminum profile is stuck into the conical groove 12. The second hydraulic cylinder 6 is activated, which drives the U-shaped connecting frame 7, the first connecting shaft 8, and the straightening roller 11 on the first connecting shaft 8 to move downward, so that the straightening roller 11 on the first connecting shaft 8 comes into contact with the aluminum profile, thus squeezing the aluminum profile. At the same time, the conical groove 12 can limit the aluminum profile and prevent the aluminum profile from deforming during the straightening process. The push plate 5 is moved by the first hydraulic cylinder 4 to apply pressure to one end of the aluminum profile, pushing the aluminum profile to move between the two sets of straightening rollers 11, thereby straightening the aluminum profile.

[0030] When the straightening roller 11 needs to be replaced, the clamping plate 21 is moved to separate it from the connecting column 13, and the U-shaped connecting frame 7 can be removed from the first hydraulic cylinder 6. The round hole 16 on the surface of the U-shaped connecting frame 7 on the other specification straightening roller 11 is aligned with the connecting column 13, so that the connecting column 13 passes through the round hole 16, so that the retaining ring 15 contacts the surface of the U-shaped connecting frame 7, and the annular groove 14 is located inside the U-shaped connecting frame 7. Then the clamping plate 21 is moved so that the clamping groove 22 and the annular groove 14 mesh with each other. The round rod 19 and the clamping plate 21 are pulled by the spring 18, so that the clamping plate 21 can be in close contact with the connecting column 13. When replacing the second connecting shaft 9 and the straightening roller 11, the second connecting shaft 9 can be removed from the rectangular frame 2 along the horizontal groove 24 and the vertical groove 25. Then the other specification straightening roller 11 and the second connecting shaft 9 can be inserted into the vertical groove 25 along the horizontal groove 24. The baffle 26 is used to limit the second connecting shaft 9.
