Description

Technical Field

[0001] This utility model relates to the technical field of profile extrusion forming equipment, and in particular to an online shaping equipment suitable for extruding profiles with complex cross-sections. Background Technology

[0002] Currently, online forming is used to shape extruded profiles. Generally, online forming equipment is installed at the outlet of the extrusion equipment. Due to the influence of extrusion process conditions and die structure, aluminum alloy may experience uneven flow rate during extrusion, resulting in insufficient flatness such as warping and wavy profiles in the extrusion direction. However, existing online forming equipment has poor adjustability, is prone to material blocking, and is difficult to adapt to the online forming process of the above-mentioned extrusion forming process. Furthermore, it is difficult to adapt to the online forming of profile products with different cross-sectional shapes and irregular structural features. Utility Model Content

This allows for shaping without damaging the local irregular cross-sectional features of the profile, thus adapting to profile components with different cross-sectional shapes and sizes. Simultaneously, the first lifting component adjusts the overall height of the shaping mechanism in the vertical direction, including the upper and lower roller groups, to adjust the height of the profile channel between the upper and lower roller groups. The second lifting component adjusts the vertical distance between the upper and lower roller groups relative to the lower roller groups, thereby adjusting the vertical opening of the profile channel between the upper and lower roller groups, providing more space for profile extrusion and solving material blocking problems that may occur during the extrusion shaping process. It features flexible control and strong adaptability.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0044] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0045] Aluminum alloys are increasingly widely used in aerospace, rail transportation, automotive, and construction industries due to their advantages such as high specific strength, good corrosion resistance, and high recyclability. Aluminum alloy extruded profiles, as an important type of aluminum alloy structural component, account for a considerable proportion.

[0046] The extrusion process of aluminum alloy profiles is usually carried out at high temperatures. After the profile is extruded from the extrusion equipment, it remains at a high temperature. Due to the softening of the material, the profile is affected by the flow rate determined by the die design and its own weight, and will inevitably deform to some extent during the continuous extrusion process. Offline shaping is usually required before the product leaves the factory to ensure product quality. However, offline shaping is usually performed after the parts have cooled to room temperature, requiring relatively large shaping forces, which may even damage the profile, and is also relatively inefficient.

[0047] Currently, extruded profiles are shaped online. Online shaping equipment is typically installed at the outlet of the extrusion equipment. Due to the influence of extrusion process conditions and die structure, aluminum alloys may experience uneven flow rates during extrusion, resulting in insufficient flatness such as warping and wavy lines in the extrusion direction. However, existing online shaping equipment has poor adjustability, is prone to material blocking, and is difficult to adapt to the online shaping process of the aforementioned extrusion forming process. Furthermore, it is difficult to adapt to the online shaping of aluminum alloy profiles with different cross-sectional shapes and irregular structural features.

[0048] Therefore, this utility model proposes an online forming device suitable for extruding complex cross-section profiles, so as to adapt to the online forming of aluminum alloy profile products with different cross-sectional shapes and irregular structural features. On the one hand, it avoids damage to the irregular structural features of complex cross-section profiles, and on the other hand, it avoids the occurrence of material blocking problems.

[0049] like Figures 1 to 3 As shown, the online shaping device of this utility model includes a shaping mechanism and a lifting mechanism.

[0050] The shaping mechanism of this utility model includes at least one upper roller group 100 and at least one lower roller group 200. The number of upper roller group 100 and lower roller group 200 can be set to one or more, depending on the shaping process requirements. The more upper roller group 100 and lower roller group 200 there are, the better the shaping effect.

[0051] In this embodiment, two sets of upper roller assembly 100 and two sets of lower roller assembly 200 are each used as examples.

[0052] like Figure 2As shown, in this embodiment, the upper roller group 100 and the lower roller group 200 are arranged in a vertical direction. The upper roller group 100 is located above the lower roller group 200. A profile channel is formed between the lower roller group 200 and the lower roller group 200 for the extruded profile to pass through. After the profile is extruded by the extrusion equipment, it passes through the profile channel between the upper roller group 100 and the lower roller group 200 to achieve shaping.

[0053] In this embodiment, the longitudinal direction is set as the forward direction of profile extrusion, while the transverse direction is perpendicular to the longitudinal and vertical directions. In this embodiment, the two sets of upper roller groups 100 and the two sets of lower roller groups 200 are arranged at intervals along the longitudinal direction so that the profile channel also extends along the longitudinal direction.

[0054] When multiple sets of upper roller group 100 and lower roller group 200 are respectively provided, the multiple sets of upper roller group 100 are arranged at intervals along the longitudinal direction, and the multiple sets of lower roller group 200 are arranged at intervals along the longitudinal direction.

[0055] In this embodiment, the upper roller assembly 100 includes multiple upper roller bodies 110, and the lower roller assembly 200 includes multiple lower roller bodies 210. The axes of the upper roller bodies 110 and the lower roller bodies 210 extend laterally, and both the upper roller bodies 110 and the lower roller bodies 210 are rolled. In this embodiment, the outer peripheral surfaces of the upper roller bodies 110 and the lower roller bodies 210 contact the top and bottom surfaces of the profile, respectively, and the profile is shaped by the rolling upper roller bodies 110 and the lower roller bodies 210.

[0056] In this embodiment, the upper roller body 110 and the lower roller body 210 are individually adjustable and can move laterally. According to the cross-sectional shape of the profile product, by adjusting the position of the upper roller body 110 and the lower roller body 210 in the lateral direction, the rollers can avoid conflict with special structures such as ribs and reinforcing bars on the profile cross-section. This allows for shaping without damaging the local irregular cross-sectional features of the profile, thereby adapting to profile components with different cross-sectional shapes and sizes.

[0057] When adjusting the upper roller body 110 and the lower roller body 210, several adjacent upper roller bodies 110 or several lower roller bodies 210 can be stacked together in the horizontal direction. The width of each upper roller body 110 in the upper roller group 100 and each lower roller body 210 in the lower roller group 200 can be the same or different.

[0058] In some embodiments, the upper roller body 110 in the upper roller group 100 and the lower roller body 210 in the lower roller group 200 can be staggered along the longitudinal direction to expand the range of the profile shaping effect in the longitudinal direction. When the number of the upper roller group 100 and the lower roller group 200 is set to one, the profile can also be effectively shaped.

[0059] In this embodiment, multiple upper roller bodies 110 on each upper roller group 100 are arranged coaxially in the horizontal direction, and multiple lower roller bodies 210 on each lower roller group 200 are arranged coaxially in the horizontal direction. This facilitates the installation and adjustment of the upper roller bodies 110 and the lower roller bodies 210, and also makes the structure of the equipment more compact and reasonable.

[0060] Furthermore, the upper roller assembly 100 and the lower roller assembly 200 are arranged opposite each other in the vertical direction, so that when the profile is being shaped, the upper roller body 110 and the lower roller body 210 can both act on the same part of the profile, thereby improving the shaping effect.

[0061] The upper roller assembly 100 of this utility model includes an upper spindle 120, and upper roller bodies 110 are rotatably mounted on the upper spindle 120. The number of upper spindles 120 can be set to one or more. When one upper spindle 120 is set, all upper roller bodies 110 on the upper roller assembly 100 are mounted on the same upper spindle 120, and the upper roller bodies 110 are adjustablely slidable along the axial direction of the upper spindle 120. When multiple upper spindles 120 are set, the multiple upper roller bodies 110 on the upper roller assembly 100 are respectively mounted on multiple upper spindles 120, and each upper spindle 120 is fixed on a sliding arm. The position of the upper roller body 110 in the lateral direction can be adjusted by moving the sliding arm.

[0062] The lower roller assembly 200 includes a lower spindle 220, and the lower roller body 210 is rotatably mounted on the lower spindle 220. The quantitative relationship between the lower roller body 210 and the lower spindle 220 is the same as described above.

[0063] The lifting mechanism in this embodiment includes a first lifting component 300 and a second lifting component 400. The first lifting component 300 is used to drive the entire shaping mechanism to move in the vertical direction, while the second lifting component 400 drives the upper roller group 100 to move in the vertical direction relative to the lower roller group 200.

[0064] This invention uses a first lifting component 300 to adjust the overall height of the forming mechanism in the vertical direction, which includes an upper roller group 100 and a lower roller group 200, to adjust the height of the profile channel between the upper roller group 100 and the lower roller group 200. A second lifting component 400 is used to adjust the vertical distance between the upper roller group 100 and the lower roller group 200, thereby adjusting the vertical opening of the profile channel between them. This provides more space for profile extrusion, solves the material blocking problem that may occur during the extrusion forming process, and features flexible control and strong adaptability.

[0065] The second lifting component 400 can simultaneously drive all the upper roller groups 100 to move up and down together. At this time, one or more second lifting components 400 can be set. The number of second lifting components 400 corresponds one-to-one with the number of upper roller groups 100. Multiple second lifting components 400 can individually drive multiple upper roller groups 100 to move up and down, so that the profile channel can contract in a funnel shape. During operation, the opening height of the profile channel at the end closer to the extrusion equipment should be larger. Then, the opening height of the profile channel gradually decreases along the extrusion forward direction to achieve gradual shaping of the profile.

[0066] Specifically, the shaping mechanism in this embodiment includes a first lifting frame 500 and a second lifting frame 600. The lower roller assembly 200 and the second lifting component 400 are respectively installed on the first lifting frame 500, and the upper roller assembly 100 is installed on the second lifting frame 600. The first lifting component 300 is drivenly connected to the first lifting frame 500 to drive the first lifting frame 500 to move in the vertical direction, and the second lifting component 400 is drivenly connected to the second lifting frame 600 to drive the second lifting frame 600 to move in the vertical direction.

[0067] In this embodiment, when the first lifting component 300 drives the first lifting frame 500 to move up and down, it also drives the lower roller group 200, the second lifting component 400, the second lifting frame 600 and the upper roller group 100 to move up and down together, so as to realize the overall lifting and adjustment of the shaping mechanism. When the second lifting component 400 drives the second lifting frame 600 to move up and down, it also drives the upper roller group 100 installed on the second lifting frame 600 to move up and down together.

[0068] When there are multiple second lifting components 400, there are multiple second lifting frames 600. Multiple upper roller groups 100 are respectively installed on multiple second lifting frames 600, and multiple second lifting components 400 respectively drive multiple second lifting frames 600 to lift.

[0069] When one second lifting assembly 400 is provided, one second lifting frame 600 is provided, and each upper roller assembly 100 is installed on the same second lifting frame 600.

[0070] The second lifting frame 600 is slidably mounted on the first lifting frame 500 to improve the stability of the installation.

[0071] Furthermore, the online cosmetic surgery device also includes a support base 700, a first lifting assembly 300 mounted on the support base 700, and a first lifting frame 500 mounted on top of the first lifting assembly 300. In some other embodiments, the first lifting frame 500 may slide with the support base 700 to improve the stability of the installation.

[0072] In this embodiment, a mounting platform 800 is provided below the support base 700. A plurality of evenly distributed connectors are connected between the bottom of the support base 700 and the top of the mounting platform 800. The connectors are adjustable in the vertical direction to adjust the posture of the support base 700 so that the initial position of the forming mechanism matches the extrusion equipment. The connectors can be a screw and nut structure or an existing telescopic rod.

[0073] The specific structure of the first lifting component 300 and the second lifting component 400 can be a hydraulic linear drive structure, a pneumatic linear drive structure, or a linear motor drive structure, etc. The linear drive structure is an existing conventional device, and those skilled in the art can find it in the existing market according to their needs, so it will not be described in detail here.

[0074] The online cosmetic surgery device of this embodiment provides the following four implementation methods:

[0075] Implementation Method 1:

[0076] When used for online shaping of extruded aluminum alloy profiles with ribs in the middle of the cross section, such as Figure 4 As shown, the profile cross-section has multiple ribs of different heights, widths, and shapes at different locations. If a single long roller is used, the irregular structure of the profile cross-section will be damaged, severely affecting the dimensional accuracy of the cross-section. Using the online shaping equipment of this embodiment, during implementation, the upper roller 110 and lower roller 210 of appropriate width are reasonably distributed horizontally, ensuring that each upper roller 110 and lower roller 210 is in tangential contact with the flat portion of the profile, without contacting the protruding ribs. This achieves shaping while avoiding damage to the shape and dimensional accuracy of the irregular cross-section structure.

[0077] Implementation Method Two:

[0078] When used for online forming of extruded aluminum alloy profiles with flanged ends and ribbed middle sections, such as Figure 5 As shown, the profile cross-section has flange structures of a certain height at both ends in the horizontal direction, while the shape and position of the rib structure in the middle of the cross-section also change. During implementation, the width and position of the upper roller body 110 are adjusted accordingly and reasonably distributed in the horizontal direction to avoid contact with the flanges at both ends and the ribs in the middle, thus avoiding damage to the shape and dimensional accuracy of the irregular cross-section structure.

[0079] Implementation Method 3:

[0080] like Figure 6As shown, due to the influence of extrusion process conditions and mold structure, aluminum alloys may experience uneven flow rates during extrusion, resulting in insufficient flatness issues such as warping and wavy profiles. The line forming equipment in this embodiment allows for the vertical adjustment of the forming mechanism as a whole and the upper roller assembly 100 individually. During implementation, if the profile warps vertically, the upper roller assembly 100 can be moved upwards to provide more space for extrusion, allowing the profile to pass smoothly through the forming equipment and preventing material blockage. After the profile head has successfully passed through the forming mechanism, the upper roller assembly 100 can be moved downwards to contact the profile and achieve the forming purpose.

[0081] Example 4:

[0082] like Figure 7 As shown, in contrast to the situation in Embodiment 3, the profile collapses downwards after extrusion. During implementation, the profile collapses downwards in the vertical direction. At this time, the entire shaping mechanism can be moved downwards, and the upper roller assembly 100 can be moved upwards appropriately to provide more space for the profile extrusion, so that the profile can pass through the shaping mechanism smoothly and avoid the problem of material blocking. After the profile head passes through the shaping mechanism smoothly, the entire shaping mechanism can be moved upwards, and the upper roller assembly 100 can be moved downwards appropriately to make it contact the profile and achieve the shaping purpose.
