[0001] The application belongs to the technical field of aluminum profile processing, and particularly relates to a straightening device for aluminum profile production. BACKGROUND

[0002] In the aluminum profile production and processing process, due to factors such as extrusion molding process, uneven cooling speed, external force in the transportation and storage process, the aluminum profile is prone to deformation phenomena such as bending and twisting, which seriously affects the subsequent processing and use of the aluminum profile and the overall quality of the product. At present, the existing aluminum profile straightening equipment on the market is mainly divided into two categories: manual straightening equipment and semi-automatic straightening equipment.

[0003] The manual straightening equipment needs the operator to correct the deformed part of the aluminum profile by means of experience through hammering, wrenching and other ways. This straightening method not only has high labor intensity and low straightening efficiency, but also depends on the technical level of the operator for the straightening accuracy, and it is difficult to guarantee the stability of the straightening quality, and it is also easy to cause damage to the surface of the aluminum profile, forming defects such as dents and scratches.

[0004] Although the semi-automatic straightening equipment reduces manual operation to a certain extent, when clamping the aluminum profile, the clamping force is not properly controlled, which easily leads to deformation of the clamping part of the aluminum profile. In the subsequent use process, the deformed part needs to be cut off, thereby causing waste. Or because of unstable clamping, the aluminum profile deviates during the force straightening process, affecting the straightening accuracy. SUMMARY

Wherein, the base 1 as the bearing foundation of the whole device, the end fixing assembly 2 and the end support assembly 3 device are installed on the base 1, and the two work together to ensure that the aluminum profile 5 maintains an ideal stress state during straightening.

[0021] The end fixing assembly 2 is used for fixing the end of the aluminum profile 5, and the end fixing assembly 2 comprises a clamping mechanism 21 for clamping the aluminum profile 5 and a limiting mechanism 22 for limiting the transverse position of the aluminum profile 5. Among them, the clamping mechanism 21 is provided with two, two clamping mechanisms 2 are arranged along the center line of the cross section of the aluminum profile 5 symmetrically, which ensures uniform distribution of clamping force and ensures completion of the shape of the end of the aluminum profile 5. The clamping mechanism 21 comprises a clamping part, and the end of the aluminum profile 5 is clamped through the relative movement of the clamping part.

[0022] In the aluminum profile 5 conveying and positioning stage, the limiting mechanism 22 is in a vertical state, which can accurately limit the aluminum profile 5 and ensure that the aluminum profile 5 is in a preset straightening position, so as to avoid inaccurate straightening position caused by position deviation of the aluminum profile 5; after the straightening of the aluminum profile 5 is completed, the limiting mechanism 22 is in a avoiding state, which will not hinder the conveying of the aluminum profile 5, ensuring the continuity of the straightening operation and further improving the work efficiency.

[0023] The end support assembly 3 is specially used for internally supporting the aluminum profile 5 to prevent internal concave deformation during straightening and ensure that the cross-sectional shape of the profile is perfect. The end support assembly 3 comprises a connecting plate 31 and a support core 32, the support core 32 is arranged on the connecting plate 31, and the axis of the support core 32 is collinear with the axis of the aluminum profile 5 to be straightened, and the support core 32 can be inserted into the inner hole of the aluminum profile 5 to be straightened.

[0024] The end fixing assembly 2 and the end support assembly 3 work cooperatively to form a complete straightening guarantee system from external clamping and fixing to internal support and protection. Specifically, the support core 32 of the end support assembly 3 is collinear with the axis of the aluminum profile 5 and can be accurately inserted into the inner hole of the aluminum profile 5 to realize internal support, and the clamping mechanism 21 uniformly applies clamping force through the symmetrically distributed clamping parts to prevent the end of the hollow aluminum profile 5 from being concave during the stretching process, thereby causing waste of the profile and further improving the straightening quality of the aluminum profile.

[0025] Based on the above-mentioned aluminum profile straightening device, an aluminum profile straightening method is provided, which comprises the following steps: S1: conveying and positioning The aluminum profile 5 to be straightened is conveyed to the straightening area through the conveying frame 4, in the conveying process of the aluminum profile 5, the limiting mechanism 22 is in a vertical state, limiting the side surface of the aluminum profile 5, fixing the position of the aluminum profile 5 at a preset straightening position, and ensuring that the two ends of the aluminum profile 5 are aligned with the centers of the two machine bases 1; S2: clamping and fixing When the aluminum profile 5 reaches the preset straightening position, the two oppositely arranged clamping parts in the clamping mechanism 21 move towards the aluminum profile 5 until the clamping parts are in close contact with the surface of the aluminum profile 5, thereby achieving clamping and fixing of the two ends of the aluminum profile 5; S3: inner core support The support core 32 of the end support assembly 3 is inserted into the interior of the aluminum profile 5, and the interior of the aluminum profile 5 is supported by the support core 32 to prevent the end of the aluminum profile 5 from being deformed inwardly during the stretching and straightening process. S4: stretching and straightening The driving mechanism drives the clamping mechanism 21 to move to the longitudinal two sides of the aluminum profile 5, straightens the aluminum profile 5, and realizes the straightening of the aluminum profile 5.

[0026] S5: release and reset When the straightening of the aluminum profile 5 is completed, the clamping part moves away from the aluminum profile 5 to release the clamping of the aluminum profile 5; at the same time, the support core 32 moves away from the aluminum profile 5 to pull out the support core 32 from the inner hole of the aluminum profile 5; at the same time, the limiting mechanism 22 rotates and switches to the avoiding state to avoid the limiting mechanism 22 from hindering the subsequent movement of the aluminum profile 5.

[0027] Further, in some embodiments, the base 1 is provided in a C-shaped frame structure, and the opening of the C-shaped structure faces the aluminum profile 5, facilitating the entry and exit of the aluminum profile 5 and the installation and arrangement of various components. The base 1 is provided with two, and the center axes of the two bases 1 are collinear, ensuring that the stress on both ends of the aluminum profile 5 remains consistent and avoiding deformation caused by uneven stress.

[0028] Specifically, the base 1 includes a shell 11, a partition plate 16, an avoiding groove 14 for accommodating the limiting mechanism 22, and a sliding rail 15 for guiding the sliding of the clamping mechanism 21.

[0029] The shell 11 is a hollow structure, and an installation cavity is formed inside. The partition plate 16 is fixedly installed inside the shell 11, and the transmission mechanism is arranged in the installation area surrounded by the partition plate 16 and the shell 11. The end support assembly 3 is connected with the partition plate 16, the support core 32 can pass through the positioning hole pre-processed on the partition plate 16 and smoothly insert into the inner hole of the aluminum profile 5 to be straightened.

[0030] The avoiding groove 14 is opened on the side of the shell 11 close to the aluminum profile 5, and the avoiding groove 14 corresponds to the position of the limiting mechanism 22, ensuring that the limiting mechanism 22 does not affect the conveying of the aluminum profile 5 during the straightening process.

[0031] The sliding rail 15 is fixedly installed in the working area of the shell 11, and the sliding rail 15 is arranged in parallel with the transmission mechanism. The clamping mechanism 21 is in sliding cooperation with the sliding rail 15, ensuring that the clamping mechanism 21 can stably move along the sliding rail 15.

[0032] Further, in some embodiments, the transmission mechanism is used to drive the clamping mechanism 21 to longitudinally stretch the aluminum profile 5, each set of transmission mechanism includes a transmission screw rod 12 and a drive motor 13, the drive motor 13 is a servo motor, fixed to the inner side of the partition plate 16, the output end is connected with the transmission screw rod 12 through the shaft coupling, the rotation speed and the rotation angle of the transmission screw rod 12 can be accurately controlled; and one end of the transmission screw rod 12 is connected with the inner wall of the shell 11 through the bearing, the other end passes through the partition plate 16 and is connected with the drive motor 13, the transmission screw rod 12 is threadedly connected with the clamping mechanism 21, when rotating, the transmission screw rod 12 can drive the clamping mechanism 21 to slide along the slide rail 15, thereby realizing the longitudinal movement of the clamping mechanism 21.

[0033] As shown in Figures 3-6 some embodiments, the clamping mechanism 21 further includes a sliding plate 211 and a first telescopic rod 212, wherein the first telescopic rod 212 is arranged between the sliding plate 211 and the clamping part, and serves to connect the two, at the same time, the first telescopic rod 212 also serves to drive the clamping part to move in the direction of approaching or moving away from the aluminum profile 5.

[0034] The sliding plate 211 is threadedly connected with the transmission screw rod 12 in the transmission mechanism, and the sliding plate 211 stably slides along the slide rail 15.

[0035] The clamping part is a clamping jaw 213, the clamping jaw 213 is fixed to the movable end of the first telescopic rod 212, the clamping jaw 213 and the clamping surface of the aluminum profile 5 are provided with a flexible pad 214 made of nitrile rubber or polyurethane, which not only ensures the clamping stability, but also avoids damaging the surface of the aluminum profile 5, and at the same time, can increase the friction between the clamping surface and the surface of the aluminum profile 5 during the straightening operation.

[0036] As shown in Figures 7-8 some embodiments, the limiting mechanism 22 includes a limiting plate 221, a connecting rod 222 and a drive rod 223. Specifically, the drive rod 223 is installed in the internal cavity of the shell 11, which ensures its smooth and reliable operation. One end of the connecting rod 222 is hinged with the drive rod 223, and the other end is rigidly fixedly connected with the limiting plate 221 through welding.

[0037] During the work process, when the drive rod 223 rotates under the action of the external power source, it can drive the connecting rod 222 to make accurate circular motion around the hinge point, so as to realize the smooth switching of the limiting plate 221 between the vertical positioning state and the horizontal avoiding state through the transmission of the connecting rod 222, and ensure the accurate positioning and smooth conveying of the aluminum profile 5 during the straightening process.

[0038] As shown in Figures 1-5As shown, in some embodiments, the end support assembly 3 further comprises a guide roller 34 and a second telescopic rod 33. Among them, the guide roller 34 is arranged outside the partition plate 16, and the guide roller 34 is reliably connected with the bottom of the support core 32, and the guide roller 34 can flexibly rotate around its own axis, and plays a guiding and supporting role.

[0039] At the same time, the second telescopic rod 33 is arranged between the connecting plate 31 and the partition plate 16 as a driving component, the fixed end of the second telescopic rod 33 is fixedly connected with the inner side wall surface of the partition plate 16, and the movable end is connected with the connecting plate 31, and through the telescopic movement of the second telescopic rod 33, the connecting plate 31 can be effectively driven to drive the support core 32 to move linearly along the horizontal direction to approach or away from the aluminum profile 5 to be straightened. In particular, the axis of the support core 32 needs to be completely collinear with the axis of the aluminum profile 5 to be straightened during installation, so as to ensure the straightening accuracy, and a conical guide section is further designed at the front end of the support core 32, and the conical structure can effectively guide the aluminum profile 5 to be smoothly inserted into the inner hole of the aluminum profile 5.

[0040] As shown in the figure, Figures 1-2 In some embodiments, a conveying frame 4 is further included, which is arranged between the two machine bases 1 and is used to convey the aluminum profile 5 before and after straightening. During the straightening process, when the transmission mechanism drives the clamping mechanism 21 to drive the aluminum profile 5 to be longitudinally stretched, the surface of the aluminum profile 5 can be separated from the surface of the conveying roller, so as to avoid the interference of the conveying roller friction with the straightening.

[0041] The specific implementation process of the present application is as follows: S1: conveying and positioning The aluminum profile 5 to be straightened is placed on the conveying frame 4, and the conveying frame 4 conveys the aluminum profile 5 to the straightening area between the two C-shaped machine bases 1; during the conveying process of the aluminum profile 5, the drive rod 223 of the limiting mechanism 22 is started, the drive rod 223 drives the limiting plate 221 to be in a vertical state through the connecting rod 222, the limiting plate 221 limits the two sides of the aluminum profile 5, and fixes the position of the aluminum profile 5 at the preset straightening position, so as to ensure that the two ends of the aluminum profile 5 are aligned with the centers of the two machine bases 1; S2: clamping and fixing When the aluminum profile 5 reaches the preset straightening position, the first telescopic rod 212 of the clamping mechanism 21 is started, the first telescopic rod 212 drives the two oppositely arranged clamping jaws 213 to move towards the aluminum profile 5, until the flexible pad 214 on the clamping jaw 213 is in close contact with the surface of the aluminum profile 5, so as to realize the clamping and fixing of the two ends of the aluminum profile 5; S3: inner core support The second telescopic rod 33 of the end support assembly 3 is activated, and the second telescopic rod 33 pushes the connecting plate 31 to move towards the aluminum profile 5. The connecting plate 31 drives the support core 32 to pass through the partition 16 and insert into the interior of the aluminum profile 5. During the insertion of the support core 32, the guide roller 34 guides the movement of the support core 32 to ensure that the support core 32 can be accurately inserted into the inner hole of the aluminum profile 5. The support core 32 supports the interior of the aluminum profile 5 and prevents the end of the aluminum profile 5 from undergoing concave deformation during the subsequent stretching and straightening process. S4: Stretching and Straightening Two drive motors 13 are started simultaneously, driving the transmission screw 12 to rotate. Since the slide plate 211 is connected to the transmission screw 12 and slides with the slide rail 15, the transmission screw 12 drives the slide plate 211 to move along the slide rail 15 to both longitudinal sides of the aluminum profile 5. The slide plate 211 drives the first telescopic rod 212 and the gripper 213 to move synchronously, thereby applying longitudinal tension to the aluminum profile 5 and straightening it, thus achieving the straightening of the aluminum profile 5. During the stretching and straightening process, the surface of the aluminum profile 5 briefly leaves the surface of the conveyor frame 4 to avoid the conveyor frame 4 from hindering the stretching deformation of the aluminum profile 5 and ensuring the straightening effect. S5: Release and reset After the aluminum profile 5 is straightened, the drive motor 13 is turned off, causing the transmission screw 12 to stop rotating and the slide plate 211 to stop moving. Then, the first telescopic rod 212 is activated, causing the first telescopic rod 212 to drive the gripper 213 to move away from the aluminum profile 5, releasing the grip on the aluminum profile 5. At the same time, the second telescopic rod 33 is activated, causing the second telescopic rod 33 to drive the connecting plate 31 and the support core 32 to move away from the aluminum profile 5, pulling the support core 32 out of the inner hole of the aluminum profile 5. Finally, the drive rod 223 is activated, and the drive rod 223 drives the limiting plate 221 to rotate through the connecting rod 222, retracting the limiting plate 221 into the clearance groove 14 to prevent the limiting plate 221 from obstructing the subsequent movement of the aluminum profile 5. S6: Repeated Operation The straightened aluminum profile 5 is conveyed out of the straightening area by the conveyor frame 4, and the next aluminum profile 5 to be straightened is conveyed to the preset straightening position. The above steps S1 to S5 are repeated to realize the continuous straightening operation of multiple aluminum profiles 5.
