Description

Technical Field

[0001] The utility model relates to an extrusion molding device, in particular to an extrusion molding device for aluminum profiles with complex cross-sections, and belongs to the technical field of aluminum profile processing. Background Art

[0002] Aluminum extrusion is based on the principle of plastic deformation of metals. An aluminum billet, heated to a suitable temperature, is placed into the barrel of an extruder. The extrusion rod then applies immense pressure, forcing the billet through a specifically shaped die hole. This creates an aluminum profile that conforms to the die's exit shape. During this process, the billet undergoes plastic deformation, and the metal particles within it rearrange under pressure, ultimately forming the desired profile structure.

[0003] In the prior art, the utility model with application number 202323258123.9 discloses an aluminum profile extrusion forming device. In order to solve the problem that the aluminum profile is prone to shaking during feeding, affecting the feeding efficiency and the feeding stability is poor, the servo motor and the rotating plate cooperate to drive the limiting wheel to limit the transportation of the aluminum profile on the placement plate, thereby avoiding the shaking of the aluminum profile during the feeding process to reduce the feeding efficiency and improve the feeding stability.

[0004] Similar to the above application, there are still some deficiencies:

[0005] Before pushing the aluminum profile, it needs to be supported by a curved placement plate. During pushing, the sliding friction between the aluminum profile and the aluminum profile will cause certain wear. In addition, during the positioning of the aluminum profile, the use of the limit mechanism needs to be actively adjusted, which makes positioning inconvenient.

[0006] Therefore, a complex cross-section aluminum profile extrusion forming device is designed to optimize the above problems. Utility Model Content

[0034] Example 1

[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, this embodiment proposes an extrusion forming device for aluminum profiles with complex cross-sections, including an extrusion bin 1, a mounting frame 101 fixed to the side of the extrusion bin 1 close to the feed port, and a hydraulic cylinder 102 horizontally fixed to the end of the mounting frame 101. Cross bars 2 are symmetrically installed on both sides of the feed port on the extrusion bin 1, and a first conveying roller 3 is evenly rotated and installed between the two groups of cross bars 2. Extrusion rollers 4 are vertically installed at both ends of the first conveying roller 3, and a spacing adjustment mechanism 5 for controlling the movement of the extrusion rollers 4 is provided between the two groups of cross bars 2.

[0036] During the extrusion of aluminum profiles, a cylindrical aluminum rod is first placed on top of the first conveyor roller 3, and the spacing adjustment mechanism 5 is used to control the extrusion rollers 4 at both ends of the first conveyor roller 3 to move toward each other, fit on both sides of the cylindrical aluminum rod, and extrude the aluminum profile to a limited position. Then, the hydraulic cylinder 102 is started to apply thrust from the end of the aluminum rod, and the aluminum rod is squeezed from the feed port to the inside of the extrusion bin 1 for extrusion molding. During the movement of the aluminum rod, the extrusion roller 4 and the first conveyor roller 3 rotate and convey the aluminum rod, reducing the friction resistance between the aluminum rod and the first conveyor roller 3, thereby reducing the wear of the aluminum rod.

[0037] Example 2

[0038] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0039] like Figure 2 As shown, as a preferred embodiment, on the basis of the above-mentioned embodiment, further, the shape of the squeezing roller 4 is dumbbell-shaped, and the surfaces of the squeezing roller 4 and the first conveying roller 3 are smooth.

[0040] The dumbbell-shaped extrusion roller 4 can increase the contact area with the cylindrical aluminum profile, ensuring the stable position of the aluminum rod, and the smooth surfaces of the extrusion roller 4 and the first conveying roller 3 further reduce the wear on the aluminum rod.

[0041] like Figure 2 、 Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the spacing adjustment mechanism 5 includes a fixed rod 501, a first slide rod 502, a vertical plate 503, a bidirectional screw 504 and a rotating component 6, the fixed rod 501 is attached to the inner side of the cross bar 2, and the tops of the two groups of fixed rods 501 are evenly and vertically installed with vertical plates 503, the vertical plates 503 are located between the two groups of first conveying rollers 3, the extrusion roller 4 is rotatably installed on the inner side of the vertical plates 503, the first slide rod 502 is evenly fixed between the two groups of cross bars 2, the first slide rod 502 is slidably connected to the fixed rod 501, and a bidirectional screw 504 is rotatably installed between the two groups of cross bars 2 near the feed port of the extrusion bin 1, the two ends of the bidirectional screw 504 are respectively threadedly connected to the fixed rod 501, and a rotating component 6 for controlling the rotation of the bidirectional screw 504 is provided between the ends of the cross bars 2.

[0042] After the aluminum rod is placed on top of the first conveyor roller 3, the rotating assembly 6 will be controlled to drive the rotation of the bidirectional screw 504. During the rotation of the bidirectional screw 504, the two sets of fixed rods 501 will be controlled to move toward each other, and then the extrusion roller 4 on the vertical plate 503 will be controlled to contact the surface of the aluminum rod, forming an extrusion limit on the side of the aluminum rod.

[0043] like Figure 2 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, three groups of first sliding rods 502 are provided, and the distances between adjacent first sliding rods 502 are the same.

[0044] During the movement of the vertical plate 503 , the plurality of first sliding rods 502 can ensure the horizontal and stable movement of the vertical plate 503 .

[0045] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the rotating assembly 6 includes a support plate 601, a rack 603, a gear 604 and a reset member, the support plate 601 is arranged in parallel in front of the feed port of the extrusion bin 1, and a rack 603 is vertically installed at the middle position of the bottom of the support plate 601, and a gear 604 meshing with the rack 603 is fixed at the middle position of the bidirectional screw 504, and a reset member is provided between the two ends of the bottom of the support plate 601 and the mounting frame 101.

[0046] During the placement of the aluminum rod, downward pressure will be applied to the support plate 601, and the support plate 601 controls the downward movement of the rack 603. During the downward movement, the rack 603 will drive the gear 604 to rotate, thereby controlling the rotation of the bidirectional screw 504, and pressing down the reset part during the downward movement of the support plate 601. When the aluminum rod and the support plate 601 are separated, the reset of the support plate 601 can be controlled.

[0047] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, a second conveying roller 602 is provided on the top of the supporting plate 601 along the length direction, and the second conveying roller 602 is rotatably connected to the supporting plate 601.

[0048] Due to the arrangement of the second conveying roller 602 , the aluminum rod will not come into direct contact with the support plate 601 . The movement of the aluminum rod will drive the rotation of the second conveying roller 602 , and no sliding friction will be generated between the aluminum rod and the support plate 601 .

[0050] When the supporting plate 601 moves downward, the return spring 605 is pressed downward. After the pressure on the top of the supporting plate 601 is lost, the return spring 605 controls the return of the supporting plate 601.

[0051] Example 3

[0052] The following further describes the solutions in Example 1 and Example 2 in conjunction with specific working methods, as described below:

[0053] When the aluminum profile is extruded, the cylindrical aluminum rod is first placed on the top of the first conveyor roller 3. The aluminum rod will exert downward pressure on the second conveyor roller 602 on the top of the support plate 601. When the support plate 601 moves downward, the return spring 605 is pressed downward, and the support plate 601 controls the downward movement of the rack 603. The rack 603 drives the gear 604 to rotate during the downward movement, thereby controlling the rotation of the bidirectional screw 504. During the rotation of the bidirectional screw 504, the two sets of fixed rods 501 are controlled to move toward each other, thereby controlling the contact between the extrusion roller 4 on the vertical plate 503 and the surface of the aluminum rod. , forming an extrusion limit on the side of the aluminum rod. At this time, the bottom and side of the aluminum rod are all limited. Then, the hydraulic cylinder 102 is started to apply thrust from the end of the aluminum rod, and the aluminum rod is squeezed from the feed port to the inside of the extrusion bin 1 for extrusion molding. During the movement of the aluminum rod, the extrusion roller 4 and the first conveyor roller 3 rotate and convey the aluminum rod to reduce the friction resistance between the aluminum rod and the aluminum rod, thereby reducing the wear of the aluminum rod. After the aluminum rod completely enters the interior of the extrusion bin 1, as the hydraulic cylinder 102 resets, the reset spring 605 at the bottom of the support plate 601 controls the automatic reset of the support plate 601.

[0054] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
