Description

Technical Field

[0001] This utility model relates to the field of aluminum rod straightening technology, and in particular to a hollow aluminum rod straightening device with a protective structure. Background Technology

[0002] Straightening hollow aluminum bars significantly improves their straightness and dimensional accuracy, making them more suitable for engineering requirements and thus enhancing the quality of the final product. By removing internal stress, the straightening process enhances the structural stability of the aluminum bars, reducing the risk of deformation or breakage during use. The improved surface quality makes subsequent processing, such as welding and cutting, smoother.

[0003] Chinese patent CN219683634U discloses a stretching device for easy stretching and straightening, belonging to the field of aluminum rod processing technology. It includes a worktable and an aluminum rod. Two sets of symmetrically designed isolation baffles are fixedly installed on the top of the worktable. A first stretching roller and a second stretching roller are rotatably connected between the two sets of isolation baffles via rotating shafts, and the rotating shafts of the first and second stretching rollers are connected by a transmission belt. This invention, through the straight channel formed by the first and second stretching rollers, can achieve an efficient straightening effect on the aluminum rod. Furthermore, through the speed difference between the first and second stretching rollers, the aluminum rod is simultaneously conveyed and stretched and straightened in segments. Compared with existing technologies, by heating the aluminum rod and then gradually straightening it in segments, residual stress in the aluminum rod can be effectively removed, while the strength of the stretching and straightening devices required can be reduced, ensuring that the physical properties of the aluminum rod remain unchanged.

[0004] However, this technical solution may cause injury to operators due to debris during use. In existing technologies, protective covers are usually used to protect the parts being processed. The protective covers are made of transparent material, which allows for clear observation of the internal processing conditions and facilitates timely adjustments by the operators. However, the fine debris generated during processing will adhere to the inner wall of the protective cover, affecting its visibility. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a hollow aluminum rod straightening device with a protective structure. This invention aims to improve upon the existing technology where protective covers are used to protect the processing parts and allow operators to observe clearly, but the fine debris generated during processing can adhere to the inner wall of the protective cover, affecting the clarity of observation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A hollow aluminum rod straightening device with a protective structure includes a base, a protective cover fixedly connected to the top of the base, a second motor mounted on the inner wall of the protective cover, a rotating disk fixedly connected to the drive end of the second motor, two first connecting rods fixedly connected to the inner wall of the rotating disk, and a second connecting rod rotatably connected to the other end of each of the first connecting rods, two cleaning rings slidably connected to the inner wall of the protective cover, and the other end of the second connecting rod rotatably connected to the outside of the cleaning rings, and a drive assembly fixedly connected to the inner wall of the base for driving the straightening structure to a defined position.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a motor, the drive end of which is fixedly connected to a gear ring, and two gear plates are slidably connected to the inner wall of the base, with the outer sides of the two gear plates meshing with the outside of the gear ring.

[0010] As a further description of the above technical solution:

[0011] A connecting plate is fixedly connected to the top of each of the two toothed plates, and a straightening plate is fixedly connected to the top of each of the two connecting plates.

[0012] As a further description of the above technical solution:

[0013] A motor is mounted on the outside of the base, and a rotating shaft is rotatably connected to the inner wall of the base.

[0014] As a further description of the above technical solution:

[0015] The drive end of the motor is fixedly connected to the outside of the rotating shaft, and a rotating ring is fixedly connected to the other end of the rotating shaft.

[0016] As a further description of the above technical solution:

[0017] A fixed straightener is installed on the top of the base, and multiple telescopic columns are fixedly connected to the top of the base.

[0018] As a further description of the above technical solution:

[0019] A lifting plate is fixedly connected to the top of the multiple telescopic columns, and a multiple straightening rollers are fixedly connected to the bottom of the lifting plate.

[0020] As a further description of the above technical solution:

[0021] The rotating ring is movably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to the outside of the lifting plate.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) This utility model uses the position change of two connecting rods to drive the position of two cleaning rings to change left and right, thereby cleaning the observation area from the side. By regularly cleaning the protective cover, its transparency can be ensured, which makes it easy for operators to monitor the processing process in real time and promptly discover and deal with potential problems.

[0024] (2) The present invention uses the mutual approach of two connecting plates to drive the mutual approach of two straightening plates. The lateral limit helps to prevent the material from shifting or twisting in the width direction. The lifting plate drives multiple straightening rollers to change position, thereby cooperating with the fixed straightener to limit the displacement of the longitudinal straightening mold, which can prevent the material from being overstretched or compressed in the longitudinal direction, so that the product is more in line with the required longitudinal dimensions.

[0025] In summary, the present invention has advantages such as cleaning the protective cover for observation and improving the straightening effect. Attached Figure Description

[0033] Example

[0034] like Figures 1 to 2 As shown, this embodiment provides a hollow aluminum rod straightening device with a protective structure, including a base 1. A protective cover 15 is fixedly connected to the top of the base 1, and the base 1 supports and fixes the position of the protective cover 15. A second motor 16 is installed on the inner wall of the protective cover 15, and the protective cover 15 supports and fixes the installation position of the second motor 16. A rotating disk 17 is fixedly connected to the drive end of the second motor 16. When the second motor 16 is started, the rotation of the drive end of the second motor 16 drives the rotating disk 17 to rotate. Two connecting rods 18 are fixedly connected to the inner wall of the rotating disk 17. The rotation of the rotating disk 17 drives the two connecting rods 18 to rotate around the center of the rotating disk 17. The other end of each of the two connecting rods 18 is rotatably connected to a second connecting rod 19 (as shown in the attached figure). Figure 2 Link 18 is a telescopic rod; its rotation causes one end of link 219 to change position. Two cleaning rings 20 are slidably connected to the inner wall of the protective cover 15, providing support and fixing the position of the two cleaning rings 20. The other end of link 219 is rotatably connected to the outside of the cleaning rings 20; the position of link 219 changes the position of the cleaning rings 20.

[0035] Reference Figures 3 to 5The inner wall of base 1 is fixedly connected to a drive assembly for driving the straightening structure to a defined position. Base 1 supports and fixes the position of the drive assembly. The drive assembly includes a motor 2, and a gear ring 3 is fixedly connected to the drive end of motor 2. When motor 2 is started, the position of the drive end of motor 2 changes, causing the gear ring 3 to rotate. Two gear plates 4 are slidably connected to the inner wall of base 1, and base 1 supports and fixes the position of the two gear plates 4. The two gear plates 4 are externally meshed with the outside of the gear ring 3 (as shown in the attached diagram). Figure 5 The positional change of the toothed ring 3 causes the two toothed plates 4 to move closer or further apart. A connecting plate 5 is fixedly connected to the top of each of the two toothed plates 4; the positional change of the toothed plates 4 causes the position of the connecting plates 5 to change accordingly. A straightening plate 6 is fixedly connected to the top of each of the two connecting plates 5; the positional change of the connecting plates 5 causes the position of the straightening plates 6 to move closer or further apart, thereby fixing the straightened position in the lateral direction.

[0036] A rotating shaft 8 is rotatably connected to the inner wall of the base 1. The base 1 supports and fixes the rotating shaft 8, which is used to connect and transmit rotation. A motor 7 is mounted on the outside of the base 1. The drive end of the motor 7 is fixedly connected to the outside of the rotating shaft 8. When the motor 7 is started, the rotation of the drive end of the motor 7 drives the rotating shaft 8 to rotate. A rotating ring 9 is fixedly connected to the other end of the rotating shaft 8. The rotation of the rotating shaft 8 drives the rotating ring 9 to rotate. A connecting rod 10 is movably connected inside the rotating ring 9. The rotation of the rotating ring 9 causes the inner wall of the connecting rod 10 to rotate around the center of the rotating ring 9. A fixed straightener 14 is fixedly connected to the top of the base 1. The base 1 supports and fixes the fixed straightener 14.

[0037] The top of the base 1 is fixedly connected to multiple telescopic columns 11 (as shown in the attached figure). Figure 3 The base 1 provides support and fixation for the multiple telescopic columns 11, which help maintain the stability of the lifting plate 12 during lifting and lowering, and provide support when the lifting plate 12 remains stationary. The lifting plate 12 is fixedly connected to the top of the multiple telescopic columns 11, and the telescopic columns 11 provide support for the lifting plate 12. Multiple straightening rollers 13 (as shown in the attached figure) are fixedly connected to the bottom of the lifting plate 12. Figure 5 The straightening roller 13 rotates during operation, and the aluminum tube at the extrusion center straightens the aluminum tube. The straightening plate 6 and the outer end of the fixed straightener 14 are both existing technologies that can straighten small aluminum tubes by approaching the extrusion. The other end of the connecting rod 10 is rotatably connected to the outside of the lifting plate 12. The position change of one end of the connecting rod 10 drives the lifting plate 12 to rise and fall, thereby controlling the straightening scale from the longitudinal position.

[0038] Work steps

[0039] Step 1: Start motor 2 (16). The positional change of the drive end of motor 2 (16) causes the rotating disk 17 to rotate. The rotation of the rotating disk 17 causes one end of the two connecting rods 18 to rotate around the center of the rotating disk 17. The rotation of the two connecting rods 18 causes one end of the two connecting rods 19 to change position. The positional change of the two connecting rods 19 causes the two cleaning rings 20 to change position left and right, thereby cleaning the observation area from the side. During the processing, the inner wall of the protective cover 15 is easily contaminated with fine debris, which affects the operator's observation of the internal processing conditions. By regularly cleaning the protective cover 15, its transparency can be ensured, allowing the operator to monitor the processing process in real time and promptly identify and deal with potential problems.

[0040] Step 2: When using, pull the aluminum rod to be straightened through the small hole on the outside of the protective cover 15 to a position close to the lateral position limit. Start motor 2. The rotation of the drive end of motor 2 drives the gear ring 3 to rotate. The rotation of gear ring 3 drives the two gear plates 4 to move closer to each other. The movement of the two gear plates 4 drives the two connecting plates 5 to move closer to each other. The movement of the two connecting plates 5 drives the two straightening plates 6 to move closer to each other. The lateral limit helps to prevent the material from shifting or twisting in the width direction, ensuring its dimensional accuracy in the plane.

[0041] The aluminum rod is continuously pushed, gradually approaching the longitudinal position limit. The rotation of the drive end of motor 7 drives the rotating shaft 8 to rotate, which in turn drives the rotating ring 9 to rotate. The rotation of the rotating ring 9 causes one end of the connecting rod 10 to rotate around its center. This positional change of the connecting rod 10 causes the other end of the connecting rod 10 to rise or fall, thereby causing the lifting plate 12 to move multiple straightening rollers 13. This works in conjunction with the fixed straightener 14 to limit the displacement of the longitudinal straightening die, preventing excessive stretching or compression of the material in the longitudinal direction, thus ensuring the product meets the required longitudinal dimensions. Here, the fixed straightener 14 and the straightening plate 6 contain multiple rollers in existing technology. The straightening rollers 13 are the rollers mentioned above. The aluminum rod is straightened using rotating rollers, and the straightening amount is controlled by adjusting the gap and angle of the rollers. This method is suitable for continuous production lines and can achieve high-efficiency straightening operations.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
