[0002] Aluminum alloy extruded profiles are increasingly widely used in fields such as battery box base plates for new energy vehicles. However, when the cross-sectional width of the extruded profile is wide or the wall thickness is thin, the profile is prone to warping along the width direction during extrusion and quenching due to uneven cooling and residual stress release in different parts of the cross-section. In severe cases, the flatness can exceed, for example, 2 mm / m, affecting the subsequent machining, assembly and use of the extruded profile. Utility Model Content

[0023] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a shaping fixture, which includes a plurality of rollers 1 arranged on the upper and lower sides of the extruded profile 8, and the plurality of rollers 1 on the upper and lower sides of the extruded profile 8 are distributed sequentially along the length direction of the extruded profile 8.

[0024] At least one roller 2 is fitted on each roller shaft 1; the axial dimension of the roller 2 is smaller than the width of the extruded profile 8, and the axial position of each roller 2 on the corresponding roller shaft 1 can be independently adjusted to adjust the contact position between the roller 2 and the extruded profile 8 in the width direction.

[0025] The position of at least one of the rollers 1 located above the extruded profile 8 is adjustable in the vertical direction to adjust the gap between adjacent upper and lower rollers 2.

[0026] All the rollers 1 of the forming fixture are divided into upper and lower groups, respectively arranged on the upper and lower sides of the extruded profile 8. The upper rollers 1 are arranged sequentially along the length of the extruded profile 8, and the lower rollers 1 are also arranged sequentially along the length of the extruded profile 8. The lower rollers 1 can support the extruded profile 8 from below, and the rollers 2 on them can form a lower positioning reference for the extruded profile 8 in the vertical direction.

[0027] At least one roller 2 is mounted on each roller shaft 1, and the roller shaft 1 is used to support the roller 2. At least one of the roller shaft 1 and roller 2 can rotate relative to the frame 3 described later. In some scenarios, the roller 2 also needs to drive the extruded profile 8 to move forward. In this case, the roller shaft 1 and roller 2 need to be fixedly connected. The roller shaft 1 is driven to rotate by a drive structure, and the roller shaft 1 drives the roller 2 connected to it to rotate together.

[0028] Each roller 2 can be independently adjusted in axial position relative to its corresponding roller shaft 1. The specific adjustment method is not limited; once adjusted to the correct position, the axial position of the roller 2 relative to its corresponding roller shaft 1 can be fixed.

[0029] The axial dimension of roller 2 (i.e., the length of roller 2 along the direction of roller shaft 1) is designed to be smaller than the width of extruded profile 8. For example, if the width of extruded profile 8 is greater than or equal to 200 mm, the axial length of roller 2 can be set to, for example, 40 ± 10 mm.

[0030] Thus, multiple rollers 1 are arranged on the upper and lower sides of the extruded profile 8, and the multiple rollers 1 on the upper and lower sides of the extruded profile 8 are distributed sequentially along the length direction of the extruded profile 8. By adjusting the axial position of the roller 2 on the corresponding roller 1, the contact position between the roller 2 and the extruded profile 8 in the width direction can be flexibly adjusted to meet the shaping requirements of the deformed area of ​​the extruded profile 8. This method has several advantages: First, the roller 2 can only contact the deformed area in the width direction of the extruded profile 8, that is, the warped part, concentrating the roller pressure on the warped part, improving the correction efficiency, and avoiding the problem of insufficient local correction force caused by the pressure being dispersed when the roller 2 is too long and in full contact with the extruded profile 8; Second, it avoids the possibility of new deformation caused by unnecessary roller pressure on non-deformed areas, and at the same time reduces the travel resistance of the extruded profile 8 when passing through; Third, it can reduce the restriction on the contour shape of the surface of the extruded profile 8, and the surface of the extruded profile 8 can be arranged with extrusion ribs, weight reduction grooves, etc. as needed. The rollers 2 can avoid these structures and only contact the deformation area that needs to be shaped. The shaping fixture can be applied to more specifications of extruded profiles 8, which is conducive to improving the versatility of the shaping fixture. Fourthly, when necessary, multiple rollers 2 distributed along the length of the extruded profile 8 can be set to correspond to the same deformation area of ​​the extruded profile 8, so that the extruded profile 8 can be subjected to multiple roller pressures during continuous passage, ensuring the shaping effect. Fifthly, the gap between the rollers 2 in the vertical direction can be flexibly adjusted to adapt to profiles with different wall thicknesses, and it is also conducive to controlling the magnitude of the roller pressure, avoiding excessive pressure at one time, which would cause new deformation or damage to the extruded profile 8.

[0031] Overall, the shaping fixture of this utility model can shape the deformation of the extruded profile 8, such as warping, thereby improving the pass rate of the extruded profile 8. In addition, the shaping fixture has high flexibility and can be applied to the shaping of deformation at different parts of the extruded profile 8, as well as to the shaping of extruded profiles 8 of different specifications.

[0032] like Figure 1As shown, optionally, the forming fixture also includes a frame 3, a first lifting frame 4, and a first lifting adjustment mechanism 5. The roller 1 located above the extruded profile 8 is an upper roller 11, and the roller 2 on the upper roller 11 is an upper roller 21. Each upper roller 11 is provided with a first lifting frame 4 and a first lifting adjustment mechanism 5. The upper roller 11 is installed on the first lifting frame 4. The first lifting frame 4 is slidably connected to the frame 3 in the vertical direction. The first lifting adjustment mechanism 5 is connected to the frame 3 and the first lifting frame 4 respectively to drive the first lifting frame 4 to drive the corresponding upper roller 11 to rise and fall.

[0033] The frame 3 serves as the supporting skeleton of the entire forming fixture. It can be made of welded or cast steel with sufficient strength and rigidity. The frame 3 can be formed with the help of the frame of the extrusion production line described later, which will not be elaborated here.

[0034] The method by which the first lifting frame 4 and the frame 3 are slidably connected in the vertical direction is not limited. For example, the frame 3 is provided with a guide rail extending in the vertical direction, and the first lifting frame 4 is provided with a slider that cooperates with the guide rail. The smoothness of the first lifting frame 4 moving in the vertical direction is achieved through the sliding connection between the slider and the guide rail.

[0035] The structural form of the first lifting and adjusting mechanism 5 is not a limitation and will be explained in conjunction with specific embodiments later.

[0036] As described above, the upper roller shaft 11 and the first lifting frame 4 can be relatively fixed, that is, there is no relative rotation between the upper roller shaft 11 and the first lifting frame 4. For example, the first connecting piece passes through the first lifting frame 4 and is connected to the upper roller shaft 11. Alternatively, the upper roller shaft 11 and the first lifting frame 4 can be relatively rotatable. For example, the upper roller shaft 11 is connected to the first lifting frame 4 through a bearing.

[0037] Thus, the first lifting frame 4 and the frame 3 are slidably connected in the vertical direction, which helps to ensure the smoothness and guiding accuracy of the lifting movement, avoids the skewness of the upper roller 11 during the lifting process, and improves the stability and consistency of the extruded profile 8. The first lifting frame 4 is driven to lift by the first lifting adjustment mechanism 5, which makes it easier to adjust the position of the upper roller 11 in the vertical direction, which helps to improve the convenience and ease of operation of adjusting the position of the upper roller 11 in the vertical direction.

[0038] like Figure 1 As shown, optionally, the first lifting adjustment mechanism 5 includes a first lead screw 51, a first nut 52 and a first driving member 53. The first lead screw 51 is arranged in the vertical direction and is rotatably mounted on the frame 3. The first nut 52 is sleeved on the first lead screw 51 and connected to the first lifting frame 4. The first driving member 53 is connected to the first lead screw 51 and is used to drive the first lead screw 51 to rotate so as to drive the first lifting frame 4 to lift.

[0039] The frame 3 is equipped with an upper bearing seat and a lower bearing seat. The two ends of the first lead screw 51 are respectively mounted in the upper and lower bearing seats via bearings, allowing the first lead screw 51 to rotate freely relative to the frame 3 while restricting its axial displacement. The outer surface of the first lead screw 51 is provided with an external thread, which can be a trapezoidal or rectangular thread to improve load-bearing capacity and transmission efficiency. The inner surface of the first nut 52 is provided with an internal thread that matches the external thread of the first lead screw 51. The first nut 52 is fitted onto the first lead screw 51 and threadedly engages with it. The first nut 52 can be fixedly connected to the first lifting frame 4, for example, by bolts or welding; or it can be integrally formed with the first lifting frame 4. When the first lead screw 51 rotates, the first nut 52 moves along the axial direction (i.e., vertically) of the first lead screw 51, thereby driving the first lifting frame 4 connected to it to rise and fall, realizing the raising and lowering of the upper roller shaft 11 and its upper roller wheel 21 connected to the first lifting frame 4.

[0040] The first drive component 53 can be located at the top or bottom of the frame 3 for easy operation. The first drive component 53 and the first lead screw 51 can be connected by a coupling, gear drive, or belt drive. When the first drive component 53 outputs rotational motion, it drives the first lead screw 51 to rotate. The rotational motion of the first lead screw 51 is converted into the lifting and lowering of the first lifting frame 4 through the first nut 52, thereby realizing the lifting and lowering of the upper roller 21. By controlling the rotation direction and number of rotations of the first drive component 53, the position of the upper roller 21 in the vertical direction can be adjusted, and the contact force between the upper roller 21 and the deformation area of ​​the extruded profile 8 can be adjusted, that is, the pressure on the extruded profile 8 can be adjusted.

[0041] Thus, the first lead screw 51 and the first nut 52 can form a lead screw and nut pair. The lead screw and nut pair has the characteristics of smooth transmission and relatively accurate positioning, which is conducive to ensuring the accuracy and stability of the position adjustment of the upper roller 21 in the vertical direction. In addition, the lead screw and nut pair also has a self-locking characteristic, which is conducive to the reliable maintenance of the position of the upper roller shaft 11 in the vertical direction, ensuring its extrusion force with the extruded profile 8.

[0042] Of course, it should be understood that, in order to further enhance the reliability of the position holding of the upper roller 11, the first lifting adjustment mechanism 5 can also be equipped with a locking structure for locking the rotational position of the first lead screw 51. The locking structure can adopt relevant technologies, such as a friction clutch disposed between the first lead screw 51 and the first driving member 53. When adjustment is required, the friction clutch engages, and the first driving member 53 drives the first lead screw 51 to rotate. After adjustment, the friction clutch disengages, and the lead screw is pressed by the friction plate and cannot rotate freely.

[0043] like Figure 1As shown, optionally, the first driving component 53 includes either a first adjusting handwheel 531 or a first driving motor.

[0044] When the first driving component 53 uses the first adjusting handwheel 531, the first adjusting handwheel 531 is fixedly installed at the upper or lower end of the first lead screw 51. The operator drives the first lead screw 51 to rotate by turning the handwheel clockwise or counterclockwise, which in turn drives the first lifting frame 4 and the upper roller shaft 11 to rise and fall via the first nut 52. The first adjusting handwheel 531 can be equipped with scale markings so that the operator can intuitively understand the adjustment amount. The manual adjustment method is simple in structure and low in cost, suitable for scenarios requiring frequent and flexible adjustments based on actual conditions, such as in small-batch production or debugging stages.

[0045] When the first driving component 53 uses a first driving motor, the output shaft of the first driving motor is connected to the first lead screw 51 via a coupling, gear transmission, or belt transmission. The first driving motor can be a servo motor or a stepper motor. Electric drive offers high adjustment precision, fast response speed, and easy integration with the control system of the entire production line, making it suitable for mass automated production scenarios.

[0046] In some scenarios, simply adjusting the position of the upper roller 11 in the vertical direction may not be sufficient to meet all shaping needs. For example, when the wall thickness of the extruded profile 8 is large or the warping is severe, the positions of the rollers 1 on the upper and lower sides of the extruded profile 8 in the vertical direction can be adjusted separately, providing greater flexibility in adjustment.

[0047] like Figure 1 As shown, optionally, the forming fixture also includes a second lifting frame 6 and a second lifting adjustment mechanism 7; the roller 1 located below the extruded profile 8 is a lower roller 12, and the roller 2 on the lower roller 12 is a lower roller 22; one or more lower rollers 12 are installed on the second lifting frame 6; the second lifting frame 6 is slidably connected to the frame 3 in the vertical direction, and the second lifting adjustment mechanism 7 is connected to the frame 3 and the second lifting frame 6 respectively to drive the second lifting frame 6 to drive all the lower rollers 12 to lift synchronously.

[0048] The second lifting frame 6 and the first lifting frame 4 are arranged similarly, as are the second lifting adjustment mechanism 7 and the first lifting adjustment mechanism 5. For example, the second lifting adjustment mechanism 7 includes a second lead screw 71, a second nut 72, and a second driving member 73. The second lead screw 71 is arranged vertically and rotatably mounted on the frame 3. The second nut 72 is sleeved on the second lead screw 71 and connected to the second lifting frame 6. The second driving member 73 is connected to the second lead screw 71 and is used to drive the second lead screw 71 to rotate, thereby raising and lowering the second lifting frame 6. The second driving member 73 includes either a second adjusting handwheel 731 or a second drive motor. Further details are omitted here.

[0049] In some scenarios, each second lifting frame 6 is equipped with only one lower roller shaft 12, and the position of each lower roller shaft 12 can be adjusted independently in the vertical direction, thus providing high flexibility in use. For example, when the extruded profile 8 warps downward, the lower roller shaft 12 can be driven to move upward through the second lifting adjustment mechanism 7, applying upward roller pressure to the lower convex point of the warped part from below, complementing the pressure applied by the upper roller shaft 11, enabling the forming fixture to handle more types of warping shapes.

[0050] like Figure 1 As shown, in some scenarios, multiple lower roller shafts 12 are installed on the second lifting frame 6. For example, all lower roller shafts 12 are installed on the same second lifting frame 6. In this case, all lower roller shafts 12 are raised and lowered synchronously in the vertical direction. The positions of all lower roller shafts 12 in the vertical direction are usually flush, so that all lower roller shafts 12 together form a support surface for supporting the extruded profile 8.

[0051] Optionally, the relative positions of the lower roller 12 and the second lifting frame 6 in the length direction of the extruded profile 8 are adjustable.

[0052] In some scenarios, the lower roller shaft 12 and the second lifting frame 6 do not need to rotate relative to each other. In this case, for example, the second lifting frame 6 is provided with a connecting hole. The connecting piece passes through the connecting hole along the axial direction of the lower roller shaft 12 and is connected to the lower roller shaft 12. By adjusting the relative position of the connecting piece and the connecting hole, such as switching the connecting hole, the position of the lower roller shaft 12 in the length direction of the extruded profile 8 can be adjusted. The side wall of the second lifting frame 6 near the lower roller shaft 12 can also be provided with a receiving groove. The receiving groove extends along the length direction of the extruded profile 8, such as the positive X-axis direction in the figure. The receiving groove is a blind groove. The end of the lower roller shaft 12 is arranged in the receiving groove. The bottom wall of the receiving groove in the Y-axis direction is provided with the above-mentioned connecting hole, such as an oval hole, and / or, multiple connecting holes are distributed sequentially along the X-axis direction.

[0053] In some scenarios, the lower roller shaft 12 and the second lifting frame 6 need to rotate relative to each other. In this case, the lower roller shaft 12 can be equipped with a mounting base. The lower roller shaft 12 is rotatably mounted on the mounting base and connected to the second lifting frame 6 through the mounting base. The relative positions of the mounting base and the second lifting frame 6 in the length direction of the extruded profile 8 are adjustable. The position of the mounting base can be adjusted by using the above-mentioned connecting holes and connectors. That is, the lower roller shaft 12 is connected to the connector through the mounting base, which will not be described in detail here.

[0054] In this way, the position of the lower roller 12 along the length of the extruded profile 8 can be adjusted as needed, achieving flexible adjustment of the support point of the lower roller 12. Operators can adjust the installation position of the lower roller 12 along the length direction according to the specific location of the warping of the extruded profile 8, thereby achieving positional adjustment of the upper roller 11 and lower roller 12 along the length of the extruded profile 8. This allows for coordinated adjustment of the upper and lower rollers 11 and 12 along the length of the extruded profile 8, ensuring that the upper and lower rollers 22 are aligned with the same deformation area of ​​the extruded profile 8, guaranteeing effective coordination of pressure and support. For example, for extruded profiles 8 of different thicknesses, adjacent upper rollers 11 and lower rollers 12 can be spaced at different distances along the X-axis. This allows the forming fixture to be applied to the forming of extruded profiles 8 with different wall thicknesses and degrees of warping, improving the versatility and applicability of the forming fixture.

[0055] like Figure 1 As shown, optionally, the roller 1 on the upper side of the extruded profile 8 is an upper roller 11, corresponding to the same width segment 82 to be shaped of the extruded profile 8, and multiple upper rollers 11 are distributed sequentially in the length direction of the extruded profile 8.

[0056] The same width segment 82 to be shaped refers to a specific area in the width direction of the extruded profile 8, which is the location of warping deformation. For example, when the width of the extruded profile 8 is 200mm, the warping deformation may be concentrated in the range of 100mm to 120mm in the width direction, and this range of 100mm to 120mm is a width segment 82 to be shaped. Corresponding to the width segment 82 to be shaped, a plurality of upper rollers 11 are arranged sequentially along the length direction (X-axis direction) of the extruded profile 8, and the upper rollers 21 on these upper rollers 11 are all aligned with the width segment 82 to be shaped.

[0057] If multiple upper rollers 11 distributed along the X-axis correspond to different width segments 82 to be shaped, the shaping fixture will only roll each width segment 82 to be shaped of the extruded profile 8 once. For areas with severe warping, a single roll may not be enough to completely correct the deformation.

[0058] Thus, as the extruded profile 8 passes continuously along its length, it will pass through each upper roller 11 in sequence, thereby undergoing multiple roller presses. Each roller press will cause a certain amount of plastic deformation in the warped area, and the accumulation of multiple roller presses can achieve sufficient correction of the warped area.

[0059] Optionally, along the conveying direction of the extruded profile 8, the positions of multiple upper rollers 11 arranged corresponding to the same width section 82 to be shaped are gradually lowered in the vertical direction, so as to apply increasing roller pressure to the width section 82 to be shaped when the extruded profile 8 passes through the corresponding multiple upper rollers 11.

[0060] like Figure 1 and Figure 2 As shown, exemplarily, the plurality of upper rollers 11 include a first upper roller 111, a second upper roller 112, a third upper roller 113, and a fourth upper roller 114, etc., wherein the first upper roller 111, the second upper roller 112, and the third upper roller 113 are arranged corresponding to the same width segment 82 to be shaped, and are arranged sequentially along the conveying direction of the extruded profile 8. The first upper roller 111 is located at the upstream end, and its position is the highest, that is, the gap between the upper roller 21 on the first upper roller 111 and the adjacent lower roller 22 is the largest, and the roller pressure applied to the extruded profile 8 is the smallest. The second upper roller 112 is located downstream of the first upper roller 111, and its position is slightly lower than that of the first upper roller 111. That is, the gap between the upper roller 21 on the second upper roller 112 and the adjacent lower roller 22 is reduced, and the roller pressure applied to the extruded profile 8 is increased. The third upper roller 113 is located downstream of the second upper roller 112, and its position is the lowest. That is, the gap between the upper roller 21 on the third upper roller 113 and the adjacent lower roller 22 is the smallest, and the roller pressure applied to the extruded profile 8 is the largest. The fourth upper roller 114 can be arranged corresponding to another width segment 82 to be formed, or it can be used as a spare roller 1, and its position can be set as needed.

[0061] Thus, through this gradually decreasing arrangement, the roller pressure exerted on the extruded profile 8 by the rollers 2 gradually increases as it passes through the first upper roller shaft 111, the second upper roller shaft 112, and the third upper roller shaft 113. This increasing roller pressure causes the warped portion of the extruded profile 8 to undergo initial plastic deformation during the first roller press, further deformation during the second roller press, and finally achieve the desired shaping during the third roller press. The deformation amount during each roller press is controlled within a small range, avoiding damage to the profile caused by excessive pressure in a single application.

[0062] Optionally, the shaping fixture also includes a sliding seat. The roller 2 is mounted on the roller shaft 1 via the sliding seat. The roller shaft 1 is provided with a guide structure extending along the axial direction. The sliding seat is sleeved on the roller shaft 1 and slidably connected with the guide structure. The sliding seat is provided with a threaded connection hole. Fasteners pass through the threaded connection hole, are threadedly connected to the threaded connection hole, and abut against the roller shaft 1.

[0063] For example, the guide structure can be a keyway extending axially along the roller shaft 1, with a key or protrusion on the inner side of the sliding seat that mates with the keyway; the guide structure can also be a guide rail or plane extending axially along the roller shaft 1, with a slider or plane on the inner side of the sliding seat that mates with the guide rail or plane. Guided by the guide structure, the sliding seat can slide smoothly along the axial direction of the roller shaft 1 without rotation or deflection.

[0064] The threaded connection hole extends radially along the sliding seat, penetrating its sidewall. The fastener can be a set screw or bolt, its tip passing through the threaded connection hole and abutting against the outer surface of roller 1. When adjusting the axial position of roller 2, first loosen the fastener, disengaging its tip from the surface of roller 1. Then, slide the sliding seat axially along roller 1 to the target position. Finally, tighten the fastener, pressing its tip against the surface of roller 1, locking the sliding seat in that axial position through friction. The contact surface between the fastener and roller 1 can be flat or curved to reduce damage to the roller 1 surface.

[0065] This makes it easier to adjust the position of roller 2 on the corresponding roller shaft 1.

[0066] Optionally, all rollers 1 are arranged between the quenching zone and the interrupted sawing zone of the extrusion production line.

[0067] The quenching zone refers to the area where the extruded profile 8 is rapidly cooled by a cooling medium (such as air cooling, water mist, or spray) after extrusion. The interrupted sawing zone refers to the area where the continuously extruded profile 8 is cut into segments according to a predetermined length.

[0068] Thus, after quenching and cooling but before being cut by the interrupt saw, the extruded profile 8 directly enters the forming fixture for online forming. The extruded profile 8 has just finished quenching and retains residual heat (e.g., a temperature of approximately 80°C). The material is in a hot-to-warm transition state, with relatively low yield strength and good plasticity. Applying roller pressure at this time most easily produces controllable plastic deformation, effectively eliminating warping. Simultaneously, since the profile has not yet been cut and is still in a continuous extrusion state, the forming fixture can continuously and uninterruptedly level the profile, synchronizing with the extrusion production line cycle.

[0069] In this way, the shaping device can shape the extruded profile 8 on the extrusion production line, thereby improving the production efficiency of the extrusion production line.

[0070] Optionally, the surface of roller 2 is covered with an elastic layer.

[0071] An elastic layer covers the outer circumferential surface of the roller 2. When the roller 2 contacts the extruded profile 8, the elastic layer directly contacts the surface of the extruded profile 8, rather than directly contacting the metal body of the roller 2. The elastic layer can be made of a material with good elasticity and wear resistance. For example, the elastic layer can be made of polyurethane, which has excellent elasticity, wear resistance, and oil resistance, and can maintain good shape recovery during repeated rolling processes, making it less prone to permanent deformation. The thickness of the polyurethane layer can be set according to actual needs, for example, it can be set to 3mm to 8mm. The elastic layer can also be made of rubber materials, such as natural rubber, nitrile rubber, or silicone rubber, etc. Rubber materials have good elasticity and cushioning properties, and are relatively inexpensive.

[0072] Taking an extruded alloy made from 6063-T5 aluminum alloy as an example, used for manufacturing the base plate of a battery box, its cross-sectional width is 350mm and its wall thickness is 2.0mm. After extrusion and air-cooling quenching, the profile undergoes warping deformation along its width due to uneven cooling of different parts of the cross-section. The initial flatness exceeds 2mm / m, failing to meet the flatness requirements of downstream machining and assembly. The shaping fixture of this invention is installed at the extrusion press roller conveyor, located between the quenching zone and the interrupted sawing zone. The roller 2 has a diameter of 80mm and an axial length of 40mm. The surface temperature of the extruded profile 8 after air-cooling quenching is approximately 80°C. It is continuously conveyed to the shaping fixture by the discharge roller conveyor at a speed of 8m / min. The flattened profile continues to be conveyed forward and sawn in the interrupted sawing zone. Five equally spaced measurement points are selected along the width of the profile, and the flatness at each measurement point is measured using a feeler gauge and a ruler. Measurement results show that the maximum warpage of the profile after leveling is 0.35 mm / m, which is far below the flatness standard (≤0.5 mm / m) required for downstream machining and assembly, indicating a good shaping effect.

[0073] An embodiment of this utility model also provides an extrusion production line, which includes the shaping tooling described in the above embodiment.

[0074] The components of the extrusion production line have been described previously. Exemplarily, the extrusion production line, along the conveying direction of the extruded profile 8, sequentially includes an extruder, a quenching zone, a forming fixture, and an interrupted sawing zone. The extruder is used to extrude heated aluminum alloy ingots to form extruded profiles 8 with the desired cross-sectional shape. The quenching zone, located downstream of the extruder, is used to rapidly cool the extruded profile 8, allowing the aluminum alloy to obtain a supersaturated solid solution. The forming fixture, located downstream of the quenching zone and upstream of the interrupted sawing zone, is used to continuously level the quenched extruded profile 8 online, eliminating warping deformation caused by uneven cooling. The interrupted sawing zone, located downstream of the forming fixture, is used to cut the continuously extruded profile 8 into segments of predetermined length.

[0075] This extrusion production line has all the beneficial effects of this forming fixture, which will not be elaborated here.

[0076] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
