Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum profile processing technology, specifically to an aluminum profile straightening device. Background Technology
[0002] After aluminum profiles are extruded, problems such as bending and twisting may occur. It is necessary to apply tensile force through equipment such as hydraulic straighteners, roller straighteners, and tension straighteners to eliminate internal stress through plastic deformation.
[0003] Chinese patent CN217550804U discloses an aluminum profile straightening machine, including a support frame, a clamping frame, a support block, a fixing component, an adjusting component, and several clamping blocks. The clamping frame is connected to the support frame; the fixing component is used to fix the clamping frame to the support frame; the support block is fixedly connected to the clamping frame; the adjusting component includes an adjusting bracket; the adjusting bracket is rotatably connected to the clamping frame; several clamping blocks are rotatably connected to the adjusting bracket and located directly above the support block. By operating the adjusting bracket, the adjusting bracket drives the clamping blocks to move, and the several clamping blocks approach the surface of the aluminum profile, so that the multiple clamping blocks move and fit against the surface of the aluminum profile to fix the irregular aluminum profile. However, this straightening machine still has the following problems:
[0004] 1. The straightening machine needs to grasp both ends of the aluminum profile and stretch it to straighten the aluminum profile. This will cause the two ends of the aluminum profile to be squeezed and deformed. However, manually inserting pads into the ends of the aluminum profile for support will reduce the straightening efficiency of the aluminum profile.
[0005] 2. When the straightening machine stretches the aluminum profile, it needs to hold it for a certain period of time, which puts a large load on the drive structure of the straightening machine and can easily reduce the service life of the drive structure.
[0006] Based on this, the present invention designs an aluminum profile straightening device to solve the above problems. Utility Model Content

[0016] Furthermore, the auxiliary positioning components are provided in two sets and symmetrically distributed on the front and rear sides of the right end of the movable support frame. The two auxiliary positioning components work together to position the aluminum profile between them.
[0017] Furthermore, the auxiliary positioning component includes a pressure rod and a second push rod. The end of the housing of the second push rod is hinged to the movable support frame, the middle part of the pressure rod is rotatably connected to the movable support frame, and the lower end of the pressure rod is hinged to the output end of the second push rod.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 An aluminum profile straightening device includes a base 1 and a movable support frame 3;
[0032] The movable support frame 3 is provided in two sets and symmetrically distributed on both sides of the base 1. The movable support frame 3 can be horizontally moved on the base 1 through the sliding component.
[0033] The movable support frame 3 is equipped with an inner support fixing mechanism 5, which includes an end clamping mechanism 51, an inner support mechanism 52, and an auxiliary positioning component 53. The end clamping mechanism 51 is used to clamp and fix the aluminum profile 7 vertically, and the inner support mechanism 52 is used to support the aluminum profile 7 from the inside to prevent the end of the aluminum profile 7 from deforming due to the clamping of the end clamping mechanism 51. The auxiliary positioning component 53 is used to limit the end of the aluminum profile 7 so that the inner support mechanism 52 can accurately extend into the inside of the aluminum profile 7 to achieve the support effect.
[0034] A one-way movement locking mechanism 6 is also provided between the base 1 and the movable support frame 3 to control the movable support frame 3 to move in only one direction at a time, thereby reducing the load on the moving components when stretching the aluminum profile 7.
[0035] In this utility model, when the aluminum profile 7 is moved between the two movable support frames 3, the end of the aluminum profile 7 is positioned by the auxiliary positioning component 53, the inner support mechanism 52 extends into the inner side of the end of the aluminum profile 7 to achieve the inner support effect of the end of the aluminum profile 7, and then the end clamping mechanism 51 clamps and fixes the end of the aluminum profile 7. The two movable support frames 3 move in a direction away from each other to perform the straightening operation of the aluminum profile 7, and the one-way movement locking mechanism 6 makes the movable support frame 3 move only in one direction at a time, sharing the load of the sliding component.
[0036] In this invention, the inner support mechanism 52 automatically extends into the inner side of the aluminum profile 7 before straightening to achieve the inner support function of the aluminum profile 7, preventing the two ends of the aluminum profile from being squeezed and deformed by the auxiliary positioning component 53, and automatically resets after straightening, effectively improving the straightening efficiency of the aluminum profile 7. The one-way moving locking mechanism 6 can reduce the load on the sliding component and increase its service life.
[0037] The sliding assembly includes a slide rail 2 and pulleys 4. The slide rail 2 is fixedly installed on the base 1. The front and rear sides of the movable support frame 3 are rotatably mounted with pulleys 4 for rolling along the slide rail 2 via bearings. The pulleys 4 on both sides of the movable support frame 3 are connected by shafts. A power source is provided inside the movable support frame 3 to drive the pulleys 4 to rotate. The power source can be an electric motor.
[0038] The end clamping mechanism 51 includes a support block 511, a pressure block 512, and a downward pressure drive assembly. The support block 511 is vertically slidable at the lower end of the movable support frame 3 by a limiting structure, such as a slide rail slider limiting structure. The support block 511 can be driven vertically by a hydraulic cylinder. The downward pressure drive assembly is installed at the upper end of the movable support frame 3. The drive end of the downward pressure drive assembly is fixedly connected to the pressure block 512 and is used to control the pressure block 512 to press against the support block 511 to achieve the clamping and fixing effect on the end of the aluminum profile 7.
[0039] Both the upper end of the support block 511 and the lower end of the pressure block 512 are provided with toothed structures to increase the clamping effect on the aluminum profile 7.
[0040] The pressure block 512 is composed of multiple pressure plates. When the pressure plates are damaged, only the damaged pressure plates need to be replaced to maintain the clamping effect of the support block 511 and the pressure block 512 on the aluminum profile 7, reducing the cost of use. The number of pressure plates can be increased or decreased according to the width of the aluminum profile 7, increasing the flexibility of the device.
[0041] The downward pressure drive assembly includes a rotating shaft 513, a connecting plate 514, a crossbar 515, and a first push rod 516. The rotating shaft 513 is rotatably mounted on the upper end of the movable support frame 3 via bearings.

The end of the housing of the first push rod 516 is hinged to the movable support frame 3, and the output end of the first push rod 516 is hinged to the crossbar 515. The rotating shaft 513 is fixedly connected to the pressure block 512.
[0042] The inner support mechanism 52 includes a horizontal pushing component and a pad 527. The horizontal pushing component is installed at the lower end of the movable support frame 3. The driving end of the horizontal pushing component is fixedly connected to the pad 527. The pad 527 is adapted to the inner cavity of the aluminum profile 7, and the end of the pad 527 is set as a frustoconical shape that is easy to insert into the aluminum profile 7.
[0043] The horizontal pushing assembly includes a motor 521, a drive shaft 522, a first gear 523, a push plate 524, a first rack 525, and a bracket 526. The bracket 526 is fixedly installed on the inner bottom of the movable support frame 3. The push plate 524 is slidably connected to the top of the bracket 526. One end of the push plate 524 near the support block 511 is fixedly connected to the pad block 527.
[0044] The motor 521 is fixedly connected to the side wall of the movable support frame 3. The output end of the motor 521 is fixedly connected to the drive shaft 522. The first gear 523 is fixedly connected to the drive shaft 522. The lower end of the push plate 524 is fixedly installed with the first rack 525. The first gear 523 and the first rack 525 are meshed together.
[0045] The auxiliary positioning components 53 are provided in two sets and symmetrically distributed on the front and rear sides of the right end of the movable support frame 3. The two auxiliary positioning components 53 cooperate to position the aluminum profile 7 between them.
[0046] The auxiliary positioning component 53 includes a pressure rod 531 and a second push rod 532. The end of the housing of the second push rod 532 is hinged to the movable support frame 3, the middle part of the pressure rod 531 is rotatably connected to the movable support frame 3, and the lower end of the pressure rod 531 is hinged to the output end of the second push rod 532.
[0047] In this utility model, when the aluminum profile 7 moves between the two movable support frames 3, the aluminum profile 7 is first blocked by the pressure rod 531 on one side, and then the pressure rod 531 on the other side moves, so that the two pressure rods 531 cooperate to position the aluminum profile 7 between them; the support block 511 moves vertically upward to lift the aluminum profile 7, and the motor 521 drives the first gear 523 to rotate through the drive shaft 522, so that the push plate 524 drives the pad block 527 to insert from the end of the aluminum profile 7 into the inside of the aluminum profile 7 under the cooperation of the first gear 523 and the push plate 524, so as to achieve the effect of internal support for the aluminum profile 7. Then the first push rod 516 pushes the crossbar 515, so that the rotating shaft 513 drives the pressure block 512 to flip downward until the aluminum profile 7 is clamped by the support block 511 and the pressure block 512. The two movable support frames 3 move in a direction away from each other to perform the straightening operation of the aluminum profile 7.
[0048] The unidirectional movement locking mechanism 6 includes a second gear 61, a second rack 62, a ratchet assembly, and a control assembly. The second rack 62 is fixedly mounted on the base 1, and the second gear 61 is fixedly mounted on the shaft between the pulleys 4. The second gear 61 and the second rack 62 are meshed together. Two sets of ratchet assemblies are mounted on the inner wall of the movable support frame 3 and symmetrically distributed on both sides of the second gear 61. The two sets of ratchet assemblies are used to limit the rotation of the second gear 61 in the clockwise and counterclockwise directions, respectively. The control assembly is mounted on the inner side of the movable support frame 3 and switches the limiting effect of the two sets of ratchet assemblies on the second gear 61.
[0049] The ratchet assembly includes a fixed plate 65, a spring 66, and a ratchet block 67. The fixed plate 65 is fixedly connected to the inner wall of the movable support frame 3. One end of the ratchet block 67 is rotatably connected to the inner wall of the movable support frame 3. The other end of the ratchet block 67 is engaged with the second gear 61. A spring 66 is fixedly installed between the fixed plate 65 and the ratchet block 67.
[0050] The control component includes a rotary cylinder 63 and an eccentric protrusion 64. The rotary cylinder 63 is fixedly connected to the side wall of the movable support frame 3. An eccentric protrusion 64 for actuating ratchet blocks 67 is fixedly installed at the output end of the rotary cylinder 63. The eccentric protrusion 64 is located between two ratchet blocks 67.
[0051] In this invention, when the movable support frame 3 moves, the second gear 61 rotates synchronously with the pulley 4 and rolls on the second rack 62. When the second gear 61 rotates in an unrestricted direction, it pushes the ratchet block 67 toward the fixed plate 65. When the second gear 61 wants to rotate in another direction, it is locked and restricted by the ratchet block 67, thus achieving a one-way movement control effect on the movable support frame 3. The movable support frame 3 can maintain the same position when straightening the aluminum profile 7. By cooperating with the ratchet block 67, the second gear 61, and the second rack 62, the load of the power source of the pulley 4 is shared, thereby increasing the service life of the power source. At the same time, by controlling the rotation of the eccentric protrusion 64 through the rotary cylinder 63, the ratchet block 67 on one side can be pressed against the fixed plate 65, changing the rotatable direction of the second gear 61.
