Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile reprocessing, specifically an automatic shaping device for aluminum profile straightening machine. Background Technology

[0002] In the reprocessing of aluminum profiles, industrial aluminum profiles have strict requirements for straightness and torsion. When excessive twisting or other defects occur, reprocessing is required to correct them. Currently, the industry generally adopts a manual-assisted basic fixture operation mode, where workers manually place or insert the aluminum profile into the fixture, and then shape it after it is fixed by the fixture.

[0003] When manually inserting aluminum profiles, precise alignment with the fixture positioning points is required, which is time-consuming and labor-intensive, especially for long profiles. Single-person operation is prone to positioning errors. Furthermore, the fixture fixation relies on hydraulic presses or screw clamping mechanisms, which not only increases the cost of equipment purchase and maintenance, but also causes production line downtime due to hydraulic pipeline leaks, screw jamming, and other malfunctions. The fixture has a fixed height and only rotational freedom, which means that aluminum profiles must be inserted from a position higher than the frame or platform. Otherwise, they will interfere with the platform during rotation and shaping. For profiles with large curvature, the insertion difficulty increases significantly. After shaping, the profiles must be manually removed from the fixture. If rework is required, manual loading, fixing, and shaping are necessary again. The entire process is cumbersome and seriously restricts the improvement of production efficiency. Utility Model Content

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] As attached Figure 1 To be continued Figure 4 As shown:

[0029] This utility model provides an automatic shaping device for aluminum profile straightening machine, including a straightening machine 1, a track platform 2, a first lifting component 3, a gantry trolley 4, a second lifting component 5, a telescopic bracket 8, and a pad support structure. The pads and notches, as well as the pads and the gantry trolley, form a square iron frame, thereby fixing the clamps on all four sides. The mechanical limiting and fixing of the clamps is achieved by cooperating with the pads, replacing the traditional hydraulic / screw clamping system and preventing the clamps from shifting.

[0030] As attached Figure 1 To be continued Figure 3 As shown: The straightening machine 1 is installed at the end of the track platform 2. Its rotating end has a notch (iron frame structure, with high-strength steel material on the inside). The gap between the inner wall of the notch and the outer circumference of the first mold 304 is ≤0.5mm, which is used for four-sided limiting clamping. It achieves mechanical limiting and fixing of the fixture by cooperating with the pad block, replacing the traditional hydraulic / screw clamping system. The back of the rotating end has a through groove 10, which communicates with the notch and has a built-in ejection actuator 6 (cylinder driven) for ejecting the aluminum profile from the fixture and demolding it after shaping.

[0031] The track platform 2 is laid along the X-axis on the feeding side of the straightening machine 1. The flatness of the platform surface is ≤0.1mm / m, and it is used to support aluminum profiles and moving parts of the equipment. A positioning plate 11 is provided at one end near the straightening machine 1, perpendicular to the X-axis, for end positioning when feeding aluminum profiles, to ensure the positional accuracy of the clamps.

[0032] As attached Figure 1 To be continued Figure 3 As shown: The first lifting assembly 3 is fixed to the top of the rotating end of the straightening machine 1, and includes a first lifting actuator 301, a first mold base 302, a first guide rod 303 and a first mold 304.

[0033] The first lifting actuator 301 is installed vertically along the Z-axis, and its output end is connected to the first mold base 302 to drive it to move up and down. It can be one of a servo electric cylinder, hydraulic cylinder or pneumatic cylinder.

[0034] Two first guide rods 303 are symmetrically distributed on the first mold base 302, and their upper ends pass through the upper wall of the notch groove.

[0035] The first mold 304 is detachably installed at the bottom of the first mold base 302. It is provided with a through groove that is compatible with the aluminum profile, and it can achieve the "lifting-lowering" action as it rises and falls.

[0036] As attached Figure 1 To be continued Figure 4 As shown: The gantry trolley 4 is mounted on the track platform 2. The bottom of the trolley is connected to the track via rollers. The gear driven by the servo motor moves along the rack and pinion to move the second lifting assembly 5 above the aluminum profile.

[0037] The second lifting assembly 5 is installed on the crossbeam of the gantry trolley 4 and includes a second lifting actuator 501, a second mold base 502, a second guide rod 504 and a second mold 503.

[0038] The second lifting actuator 501 is installed vertically, and its output end is connected to the second mold base 502 to drive it to move up and down. It adopts a servo electric cylinder, hydraulic cylinder or pneumatic cylinder of the same specification as the first lifting actuator 301.

[0039] Two second guide rods 504 are installed on the second mold base 502, and their upper ends pass through the crossbeam of the gantry trolley 4 to ensure lifting stability;

[0040] The second mold 503 is detachably installed at the bottom of the second mold base 502 and is coaxial with the first mold 304. It is adapted to the other end of the aluminum profile and works with the first mold 304 to realize the two ends of the aluminum profile being fitted together. The groove of the second mold 503 adopts a non-through design. After the profile is inserted into place, it pushes the aluminum profile to move towards the first mold 304.

[0041] As attached Figure 1 To be continued Figure 4As shown: The telescopic bracket 8 is installed on the side of the gantry trolley 4 away from the straightening machine 1 via the connecting frame 7. It includes a telescopic actuator 801, a support plate 802, and a guide rod 803. The telescopic actuator 801 can be one of a servo electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. The telescopic actuator 801 is installed along the X-axis, and its output end is connected to the support plate 802. The support plate 802 is used to place the pad and can move along the X-axis under the drive of the telescopic actuator 801. The guide rod 803 ensures that the straightness of the support plate 802 movement is ≤0.05mm / m. The shape and size of the pad can be customized according to processing needs. The mechanical limiting and fixing of the fixture is achieved by the cooperation between the gantry trolley 4 and the pad, replacing the traditional hydraulic / screw clamping system.

[0042] As attached Figure 1 To be continued Figure 2 As shown, the pad support structure employs methods such as first lifting and then translating to insert into the notch slot, or rotating to insert into the notch slot. If the pad support structure uses a rotating insertion method, it includes a rotating bracket 9 mounted on the right side of the rotating end of the straightening machine 1, which consists of a rotary actuator 902 and a swing arm 901. One end of the swing arm 901 is connected to the output shaft of the rotary actuator 902, and the other end holds the pad. Rotation can feed the pad from the through slot 10 into the notch slot, supporting the bottom of the first mold 304. The rotary actuator 902 uses a stepper motor.

[0043] Working principle: Place the aluminum profile on the track platform 2, with the end close to the positioning plate 11 to complete the initial positioning.

[0044] The gantry trolley 4 moves along the X-axis to above the aluminum profile. The second lifting actuator 501 drives the second mold 503 to descend along the Z-axis and insert into the inner hole at one end of the aluminum profile. Simultaneously, the first lifting actuator 301 drives the first mold 304 to rise along the Z-axis until it is aligned with the other end of the aluminum profile. The gantry trolley 4 moves the aluminum profile to the rotating end of the straightening machine 1. The first mold 304 descends and inserts into the inner hole at the other end of the aluminum profile, completing the two-end take-off.

[0045] The first lifting actuator 301 drives the first mold 304 to rise, lifting the aluminum profile and separating it from the track platform 2; the swing arm 901 of the rotating bracket 9 rotates, sending the pad from the through groove 10 into the notch groove, located at the bottom of the first mold 304; at the same time, the support plate 802 of the telescopic bracket 8 moves the pad horizontally and inserts it, located under the second mold 503; the first mold 304 descends, its bottom pressing on the pad, and the inner wall of the notch groove clamps the first mold 304 from all four sides, completing the fixation. The rotating end of the straightening machine 1 drives the first mold 304 and the second mold 503 to rotate, correcting the deformation of the aluminum profile.

[0046] After the shaping is completed, the first mold 304 rises, removes the pad, and then falls down to let the aluminum profile fall onto the track platform 2; the actuator 6 pushes the aluminum profile out of the mold, and the gantry trolley 4 drives the second mold 503 to detach from the aluminum profile; the operator manually checks the shaping accuracy of the aluminum profile on the track platform 2, and unqualified products can be directly re-shaped by the gantry trolley 4 without secondary feeding.

[0047] The embodiments of this utility model are given for the purpose of illustration and description. Although the embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model.
