It includes: an aluminum profile stretching mechanism that stretches the aluminum profile at both ends; and an aluminum profile auxiliary straightening mechanism positioned above the stretching mechanism that compresses the aluminum profile on both sides. In this utility model, the stretching mechanism and the auxiliary straightening mechanism work synchronously. Axial stretching eliminates longitudinal bending, and lateral compression corrects torsional deformation. The synergistic effect of both not only shortens the step-by-step straightening process time but also greatly improves the thoroughness of straightening, ensuring straightening accuracy and efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile production and processing equipment, and in particular to an automatic aluminum profile straightening machine. Background Technology

[0002] Aluminum profiles are alloy materials with aluminum as the main component. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, the mechanical properties and application fields of the industrial aluminum profiles produced are different depending on the proportion of alloys added. During the production and processing of aluminum profiles, they often undergo different degrees of twisting, resulting in bending or stretching deformation. Therefore, straightening machines are one of the most frequently used machines in aluminum profile processing.

[0003] A search revealed Chinese Patent Publication No. CN107661911A, which discloses an automatic aluminum profile straightening machine. The machine includes a frame with a guide rail rack and a fixing device and a moving device respectively mounted on the guide rail rack. The moving device is equipped with a gear and a hydraulic cylinder with a drive gear. Both the fixing and moving devices are equipped with clamping devices, each including a U-shaped frame. Rubber pads are placed on both the upper and lower sides of the U-shaped frame, and pressure sensors are mounted on the rubber pads. An infrared sensor is located inside the U-shaped frame, and a camera is mounted on one side of the moving device. A smart ruler is mounted on the frame. However, when using this technology, the U-shaped frame blocks both ends of the aluminum profile during fixing, limiting the total length of the profile. More importantly, this technology only uses a clamping cylinder to hold and stretch the aluminum profile at both ends, resulting in poor straightening performance and high pressure on a single drive component. Therefore, an automatic aluminum profile straightening machine is provided to address these problems. Utility Model Content

The embodiments of this utility model will be described below based on its overall structure.

[0025] Reference Figures 1 to 4 In this embodiment of the utility model, an automatic aluminum profile straightening machine includes:

[0026] Aluminum profile stretching mechanism 1 stretches the aluminum profile at both ends;

[0027] The aluminum profile auxiliary straightening mechanism 2 is set above the aluminum profile stretching mechanism 1, and the aluminum profile auxiliary straightening mechanism 2 extrudes the aluminum profile on both sides.

[0028] The aluminum profile stretching mechanism 1 includes a support base 11, an operating table 12 fixedly connected above the support base 11, and the operating table 12 is fixedly connected to the support base 11 above by four sets of support feet provided below. Four sets of vertical fixing plates 13 are symmetrically fixedly connected above the operating table 12. Each set of vertical fixing plates 13 is fixedly connected to a set of first electric telescopic rods 14 on its side. Two sets of upper moving seats 15 are symmetrically slidably connected above the operating table 12. The movable end of each pair of first electric telescopic rods 14 is fixedly connected to the side of an upper moving seat 15. Two sets of second electric telescopic rods 16 with opposite directions are fixedly connected to the inner side of each set of upper moving seats 15. The movable end of each second electric telescopic rod 16 is fixedly connected to an aluminum profile clamping plate 17. Four sets of positioning sliding grooves 18 are symmetrically opened above the operating table 12. Two sets of connecting rod sliding grooves 19 that extend through to the bottom of the operating table 12 are symmetrically opened above the operating table 12.

[0029] The above scheme is adopted: when the first electric telescopic rod 14 extends or retracts, it pushes the upper moving seat 15 to move laterally along the operating table 12, and the aluminum profile is stretched in both directions through two sets of symmetrically arranged upper moving seats 15; the second electric telescopic rod 16 drives the aluminum profile clamping plate 17 to move in opposite directions to clamp the end of the profile.

[0030] The aluminum profile auxiliary straightening mechanism 2 includes a drive motor 21, which is installed inside the operating table 12. A rotating disk 22 is rotatably connected below the operating table 12. The movable end of the drive motor 21 passes through the bottom of the operating table 12 and is fixedly connected to the rotating disk 22. Two symmetrically distributed rotating arms 23 are rotatably installed at the bottom of the rotating disk 22 via a rotating shaft. Two sets of side sliding plates 24 are symmetrically arranged above the operating table 12. Multiple sets of pressure rollers 25 are rotatably connected inside the opposite side of each side sliding plate 24. Sliding blocks that are adapted to the positioning sliding groove 18 are fixedly connected below each of the two sets of side sliding plates 24, so that the side sliding plates 24 are slidably connected above the operating table 12. A connecting rod 26 is fixedly connected below the side sliding plate 24. The connecting rod 26 passes through the connecting rod sliding groove 19 and is rotatably connected to the rotating arm 23. The two ends of the rotating arm 23 are rotatably connected to the connecting rod 26 and the rotating disk 22, respectively.

[0031] Using the above scheme: when the drive motor 21 drives the rotating disk 22 to rotate, the two sets of side sliding plates 24 move synchronously towards each other along the positioning sliding groove 18 through the linkage of the rotating arm 23 and the connecting rod 26. After the pressure roller 25 contacts the side wall of the aluminum profile, it achieves lateral straightening of the profile by rolling and pressing. The crank-connecting rod mechanism of the rotating arm 23 converts the rotational motion of the rotating disk 22 into the linear displacement of the side sliding plate 24. The positioning sliding groove 18 ensures the linear displacement accuracy of the side sliding plate 24. The connecting rod sliding groove 19 provides longitudinal movement space for the connecting rod 26.

[0032] The working principle of this utility model is as follows: First, the second electric telescopic rod 16 drives the aluminum profile clamping plate 17 to move in opposite directions to clamp and fix the two ends of the aluminum profile. Then, the first electric telescopic rod 14 pushes the two sets of upper moving seats 15 to move in opposite directions along the operating table 12, and the axial straightening of the aluminum profile is achieved through symmetrical stretching action.

[0033] At the same time, when the drive motor 21 drives the rotating disk 22 to rotate, the rotational motion is converted into two sets of side sliding plates 24 moving synchronously towards each other along the positioning sliding groove 18 through the crank connecting rod mechanism of the rotating arm 23 and the connecting rod 26. After the multiple sets of pressure rollers 25 on the inner side of the side sliding plate 24 contact the side wall of the aluminum profile, they generate uniform lateral extrusion force on the profile through rolling pressure to eliminate bending deformation.

[0034] The positioning sliding groove 18 constrains the movement trajectory of the side sliding plate 24 through the sliding block, ensuring the linear motion accuracy during the stretching and straightening process. The connecting rod sliding through groove 19 provides longitudinal guidance for the lifting and lowering movement of the connecting rod 26, ensuring the transmission stability between the rotating arm 23 and the side sliding plate 24.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
