Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aluminum profile production and processing technology, and specifically relates to a straightening device for aluminum profile production. Background Technology
[0002] During the production of aluminum profiles, bending and deformation often occur due to the effects of processes such as extrusion and cooling, which seriously affects the subsequent use of the aluminum profiles. Therefore, straightening devices are needed to straighten the aluminum profiles to ensure their straightness and dimensional accuracy.
[0003] Problems with existing technology:
[0004] Existing aluminum profile straightening devices typically use rollers or similar conveying structures to transport aluminum profiles to the straightening area. However, during the straightening process, these structures often cannot be properly concealed or avoided, potentially hindering or supporting the profiles during straightening and affecting the straightening effect. This results in uneven straightening of the aluminum profiles and reduced product quality. Furthermore, the repositioning of the conveying structure in some devices is not convenient, impacting the overall efficiency of the device. Utility Model Content
[0005] The purpose of this invention is to provide a straightening device for aluminum profile production, which enables the aluminum profile to directly contact the top of the workbench, completely eliminating the interference of rollers on the support of the aluminum profile, making the bottom of the aluminum profile uniformly stressed, significantly improving the straightening flatness, and fundamentally ensuring the straightening quality.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] A straightening device for aluminum profile production includes a workbench with an installation groove inside. A movable frame is slidably installed inside the installation groove. Multiple first springs are evenly arranged at the bottom of the movable frame, and the bottom ends of the first springs are connected to the inner bottom wall of the installation groove. Multiple rollers for moving aluminum profiles are evenly arranged at the top of the movable frame, and the tops of the rollers extend outside the workbench. A hidden mechanism is provided inside the installation groove to drive the rollers to retract into the installation groove when straightening the aluminum profile.
[0008] The multiple rollers are connected by a sprocket and chain drive mechanism;
[0009] A straightening box is provided on the top of the workbench, and two first hydraulic cylinders are provided on the top of the straightening box. The output shafts of the two first hydraulic cylinders extend into the straightening box and a first straightening plate is fixed thereon.
[0010] The concealed mechanism includes two mounting ears that extend to the outside of the straightening box and are located on both sides of the first straightening plate. A top rod is fixed to the bottom of the mounting ears, and the bottom end of the top rod extends into the mounting groove and is provided with a first inclined sliding surface. The top of the movable frame is provided with a through-hole directly below the top rod.
[0011] The top of the mobile frame is provided with a first sliding groove on both sides of the insertion hole. A first slider is slidably installed inside the first sliding groove, and a spring is fixed to one side of the first slider and fixed to the inner wall of the first sliding groove.
[0012] A locking block is fixed between the tops of the two first sliders and slides in contact with the inner wall of the mounting groove. A second inclined sliding surface is provided on one side of the top of the locking block and slides in contact with the first inclined sliding surface. A locking groove that cooperates with the locking block is provided on the inner side of the mounting groove and below the locking block.
[0013] Two second hydraulic cylinders are fixed on both sides of the straightening box, and a second straightening plate is provided between the output shafts of the two second hydraulic cylinders and extending into the straightening box.
[0014] The technical effects achieved by this utility model are as follows:
[0015] The motor, sprocket, and chain in this invention work together to automatically transport the aluminum profile to the straightening area, thereby improving the continuity of the production process and work efficiency.
[0016] This invention features a design where, during the straightening process, when the first hydraulic cylinder drives the first straightening plate downwards, the mounting lugs simultaneously press down the push rod. The push rod, in conjunction with the inclined sliding surface of the locking block, causes the moving frame to precisely retract the rollers into the mounting groove. At this point, the aluminum profile directly contacts the top of the workbench, eliminating interference from the rollers' support and ensuring uniform force distribution on the bottom of the aluminum profile, thus improving straightening flatness and guaranteeing straightening quality. When the locking block moves down with the moving frame to the locking slot position, the push rod and the inclined sliding surface of the locking block engage the locking block, achieving stable positioning of the moving frame and ensuring the push rod can smoothly pass through the insertion hole, avoiding obstruction to the straightening action of the first straightening plate and allowing the straightening process to proceed without interference. After straightening is complete, the first straightening plate moves upwards, causing the push rod to disengage from the insertion hole. The spring in the first sliding groove drives the first slider to disengage the locking block from the locking slot, and the first spring then pushes the moving frame and rollers back to their original positions. The entire unlocking and resetting process requires no additional operation, is highly automated, simplifies operation steps, and improves the ease of use and work pace of the equipment.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0024] like Figures 1-2 As shown, a straightening device for aluminum profile production includes a workbench 1, an installation groove 2 is provided inside the workbench 1, a movable frame 3 is slidably installed inside the installation groove 2, a plurality of first springs 4 are equidistantly arranged at the bottom of the movable frame 3, and the bottom end of the first springs 4 is connected to the inner bottom wall of the installation groove 2, a plurality of rollers 5 for moving aluminum profiles are equidistantly arranged at the top of the movable frame 3, an opening is provided at the top of the workbench 1 corresponding to the rollers 5, and the rollers 5 extend to the outside of the workbench 1 through the opening, and a hidden mechanism is provided inside the installation groove 2 for driving the rollers 5 to retract into the installation groove 2 when straightening the aluminum profile;
[0025] Multiple rollers 5 are connected by sprockets and chain drive mechanisms, and the movable frame 3 is equipped with a motor connected to one of the rollers 5;
[0026] A straightening box 6 is provided on the top of the workbench 1. Two first hydraulic cylinders 7 are provided on the top of the straightening box 6. The output shafts of the two first hydraulic cylinders 7 extend into the straightening box 6 and are fixed with a first straightening plate 8. Two second hydraulic cylinders 16 are fixed on both sides of the straightening box 6. A second straightening plate 17 is provided between the output shafts of the two second hydraulic cylinders 16 and extends into the straightening box 6.
[0027] According to the above structure, the motor, in conjunction with the sprocket and chain, can drive the roller 5 to rotate, and the roller 5 can drive the aluminum profile to move, thus moving the aluminum profile to the straightening area; the first spring 4 is provided so that when the moving frame 3 is forced to move down, the moving frame 3 can be reset through the first spring 4, which increases the practicality of the equipment;
[0028] like Figures 2-4 As shown, the concealed mechanism includes two mounting ears 9 extending to the outside of the straightening box 6 on both sides of the first straightening plate 8. A top rod 10 is fixed to the bottom of the mounting ear 9. The bottom end of the top rod 10 extends into the mounting groove 2 and is provided with a first inclined sliding surface. The top of the movable frame 3 is provided with a through insertion hole 11 directly below the top rod 10. The top of the movable frame 3 and both sides of the insertion hole 11 are provided with first sliding grooves 12. A first slider 13 is slidably installed inside the first sliding groove 12. A spring is fixed to one side of the first slider 13 and is fixed to the inner wall of the first sliding groove 12. A locking block 14 is fixed between the tops of the two first sliders 13 and slides in contact with the inner wall of the mounting groove 2. A second inclined sliding surface is provided on one side of the top of the locking block 14 and slides in contact with the first inclined sliding surface. A locking groove 15 is provided on the inner side of the mounting groove 2 and below the locking block 14 to cooperate with it.
[0029] According to the above structure, when straightening the aluminum profile, the first hydraulic cylinder 7 is activated, which drives the first straightening plate 8 to move downward. The first straightening plate 8 presses and straightens the aluminum profile. At the same time, the first straightening plate 8 drives the push rod 10 to move downward through the mounting ear 9. The push rod 10 contacts the locking block 14 and presses the locking block 14 downward. The downward movement of the locking block 14 drives the moving frame 3 to move downward. The moving frame 3 drives the roller 5 to move downward, so that the roller 5 moves into the mounting groove 2 and the aluminum profile contacts the top of the workbench 1. Then, during the downward movement, when the locking block 14 aligns with the locking groove 15, the first inclined sliding surface at the bottom of the push rod 10 cooperates with the second inclined sliding surface at the top of the locking block 14, driving the locking block 14 to move to one side, so that the locking block 14 moves to the locking block 14. Inside, at this time, the locking block 14 is located on one side of the top rod 10 and is limited. At the same time, the bottom end of the top rod 10 continues to move through the insertion hole 11 to avoid affecting the downward straightening of the first straightening plate 8. When the first straightening plate 8 moves upward, it drives the top rod 10 to move upward, so that the top rod 10 is disengaged from the insertion hole 11 and the restriction on the locking block 14 is lifted. Through the elastic force of the spring, the first slider 13 is pushed to move. The first slider 13 drives the locking block 14 to disengage from the slot 15. Then, through the elastic force of the first spring 4, the moving frame 3 and the roller 5 are reset, which facilitates the continued conveying of the aluminum profile. The structure is simple and easy to operate. It avoids the influence of the roller 5 on the aluminum profile, improves the flatness of the bottom straightening of the aluminum profile, and improves the straightening effect.
[0030] The working principle of this utility model is as follows: When it is necessary to straighten the aluminum profile, the motor connected to the roller 5 is started first. The motor drives multiple rollers 5 to rotate through the sprocket and chain transmission mechanism. The aluminum profile is placed on the roller 5. The rotation of the roller 5 drives the aluminum profile to move and conveys the aluminum profile to the straightening area in the straightening box 6.
[0031] Next, the first hydraulic cylinder 7 and the second hydraulic cylinder 16 are activated. The output shaft of the first hydraulic cylinder 7 extends, driving the first straightening plate 8 to move downward and press and straighten the top of the aluminum profile. At the same time, the first straightening plate 8 moves downward, driving the mounting ear 9 to move downward. The mounting ear 9 drives the push rod 10 to move downward. The bottom end of the push rod 10 enters the mounting groove 2. The first inclined sliding surface of the push rod 10 contacts the second inclined sliding surface of the locking block 14 and squeezes the locking block 14 to move downward. The locking block 14 drives the first slider 13 to slide in the first sliding groove 12. At this time, the spring in the first sliding groove 12 is compressed. The locking block 14 moves downward and drives the moving frame 3 to move downward. The moving frame 3 compresses the first spring 4. The roller 5 moves downward with the moving frame 3 and retracts into the mounting groove 2 through the opening on the worktable 1. After losing the support of the roller 5, the aluminum profile contacts the top of the worktable 1.
[0032] When the locking block 14 moves down to align with the slot 15, under the continued cooperation of the first inclined sliding surface of the push rod 10 and the second inclined sliding surface of the locking block 14, the locking block 14 moves to one side and enters the slot 15 to limit the locking block 14. The bottom end of the push rod 10 passes through the insertion hole 11 and continues to move down to ensure that the first straightening plate 8 can smoothly press and straighten the aluminum profile.
[0033] At the same time, the second hydraulic cylinders 16 on both sides of the straightening box 6 are activated. The output shaft of the second hydraulic cylinder 16 extends, driving the second straightening plate 17 to move to both sides of the aluminum profile to straighten the sides of the aluminum profile.
[0034] After straightening is completed, the output shafts of the first hydraulic cylinder 7 and the second hydraulic cylinder 16 are retracted. The first hydraulic cylinder 7 drives the first straightening plate 8 to move upward. The first straightening plate 8 drives the push rod 10 to move upward through the mounting ear 9. The bottom end of the push rod 10 is pulled out from the insertion hole 11 and no longer applies pressure to the locking block 14. At this time, the spring compressed in the first slide groove 12 restores its elasticity and pushes the first slider 13 to move. The first slider 13 drives the locking block 14 to move out of the slot 15, releasing the limitation on the locking block 14.
[0035] Subsequently, the movable frame 3 moves upward and resets under the elastic force of the first spring 4. The movable frame 3 drives the roller 5 to move upward, and the roller 5 extends to the outside of the worktable 1 through the opening, waiting for the next transfer of aluminum profiles.
[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
