Description

Technical Field

[0001] This utility model relates to the field of profile shaping tooling technology, specifically to a multi-roller adjustable aluminum profile online shaping device. Background Technology

[0002] Due to their large width-to-thickness ratio and low rigidity, long aluminum profiles formed by extrusion often have excessive gaps and deformation after extrusion, which makes them unacceptable. Therefore, a straightening process is required to meet the dimensional accuracy requirements of the profiles.

[0003] Current aluminum profile manufacturing processes increasingly feature thinner walls, longer cantilever lengths, more complex cross-sectional shapes, and stricter tolerance requirements. Referring to patent CN110614294A, this patent addresses the problem of low overall yield and high overall manufacturing costs caused by the current offline straightening process for long and large aluminum profiles by employing an online thermal straightening fixture. However, this patent still has the following drawbacks: it cannot simultaneously achieve straightening in multiple directions, such as simultaneously straightening bending, twisting, and warping of the aluminum profile.

[0017] Figure 2 This is a schematic diagram of the structure of the present invention and the base plate A;

[0018] Figure 3 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0020] like Figures 1 to 3 As shown, a multi-roller adjustable aluminum profile online shaping device mainly includes a mounting frame 1, a shaping roller 2, and a translation and lifting assembly 3.

[0021] like Figures 1 to 3 As shown, the mounting frame 1 includes a base plate 1b, a mounting frame body 1c, and an extension frame 1d. The mounting frame body 1c is a gantry structure, with its lower end fixedly mounted on the base plate 1b. The channel formed by the mounting frame body 1c and the base plate 1b creates a profile channel 1a for the profile B to pass through from front to back. The extension frame 1d is connected to the lower part of the base plate 1b. The base plate 1b has a seat plate connecting hole 1b1. The sliding roller table at the outlet of the aluminum profile extrusion press has a seat plate A, which has mounting holes corresponding to the seat plate connecting hole 1b1. Therefore, the base plate 1b and the seat plate A can be fixedly connected by the first connecting bolt, thereby mounting the mounting frame 1 on the sliding roller table to achieve online shaping. The base plate 1b and the mounting frame body 1c, as well as the extension frame 1d and the base plate 1b, are all detachably mounted. If the shaping device needs to be disassembled, simply unscrew the first connecting bolt at the connection between the base plate 1b and the seat plate A to separate the mounting frame 1 from the sliding roller table, which is simple and convenient. In this embodiment, the extension frame 1d can be installed on the slide roller table via the second connecting bolt, making the installation structure more stable and reliable.

[0022] like Figures 1 to 3 As shown, the translation and lifting assembly 3 is mounted on the crossbeam of the mounting frame body 1c and can move up, down, left, and right. The translation and lifting assembly 3 includes a base 3a and a worm gear assembly. The mounting frame 1 is equipped with a left-right extending base slide rail 1e and a screw 6 adapted to the base slide rail 1e. The base 3a is slidably mounted on the corresponding base slide rail 1e and forms a screw-nut kinematic pair with the corresponding screw 6. One end of each screw 6 is equipped with an adjusting nut 5 to control its rotation. The left and right sliding of the base 3a can be achieved by adjusting the nut 5.

[0023] The worm gear assembly includes a worm 3c and a worm wheel. A worm sleeve 3b is mounted on a base 3a, and a worm wheel mounting box 3d is provided on the worm sleeve 3b. The worm 3c is movably inserted into the worm sleeve 3b, and the worm wheel is rotatably mounted in the worm wheel mounting box 3d, forming a worm gear kinematic pair with the worm 3c. One end of the worm wheel extends out of the worm wheel mounting box 3d and is connected to a handle 3e. Rotating the handle 3e allows the worm 3c to move up and down. In this embodiment, a locking bolt 3f is also provided to assist in fixing the worm 3c. A mating nut 3g that is threadedly engaged with the locking bolt 3f is welded to the worm wheel mounting box 3d. A locking groove 3c1 with the same extension direction as the worm 3c is formed on the worm 3c. The inner end of the locking bolt 3f passes through the mating nut 3g and abuts against the locking groove 3c1.

[0024] like Figures 1 to 3 As shown, each translation and lifting assembly 3 has a straightening roller 2 rotatably mounted at its end near the profile channel 1a. Specifically, the straightening roller 2 is rotatably mounted at one end of the worm gear 3c near the profile channel 1a. The straightening roller 2 includes a vertically extending plane straightening roller 2a with its axis extending vertically and a horizontally extending plane straightening roller 2b with its axis extending horizontally. At least one pair of vertically extending plane straightening rollers 2a and at least one pair of horizontally extending plane straightening rollers 2b are distributed in the upper part of the profile channel 1a, and at least one pair of horizontally extending plane straightening rollers 2b are distributed in the lower part of the profile channel 1a. See also Figure 3 The horizontal straightening roller 2b can straighten the horizontal surface of profile B, while the vertical straightening roller 2a can straighten the vertical surface of profile B. By adjusting the positions of the vertical straightening roller 2a and the horizontal straightening roller 2b, profiles B of different widths and thicknesses can be straightened. Furthermore, the multi-roller straightening structure increases the contact area, thereby improving the straightening quality of profile B.

[0025] In this embodiment, a pair of horizontal plane straightening rollers 2b and a pair of vertical plane straightening rollers 2a are sequentially arranged from front to back on the upper part of the profile channel 1a. Both the horizontal plane straightening rollers 2b and the vertical plane straightening rollers 2a located on the upper part of the profile channel 1a are mounted on the crossbeam of the mounting frame body 1c. A pair of horizontal plane straightening rollers 2b and a pair of fixed straightening rollers 2d are sequentially arranged from front to back on the lower part of the profile channel 1a. Both the fixed straightening rollers 2d and the horizontal plane straightening rollers 2b located on the lower part of the profile channel 1a are mounted on the extension frame 1d. Each fixed straightening roller 2d is rotatably mounted on the extension frame 1d via a fixed mounting base 4, and the rotation axis of each fixed straightening roller 2d is parallel to the rotation axis of the horizontal plane straightening roller 2b. The fixed straightening rollers 2d can serve as a straightening reference surface for the bottom surface of profile B, offering high reliability. The outer circumference of each vertical plane straightening roller 2a, each horizontal plane straightening roller 2b, and each fixed straightening roller 2d is covered with felt. The straightening roller 2 has soft contact with the profile B, which can reduce the tearing stress on the profile B and improve the straightening success rate.

[0026] Furthermore, each worm gear 3c equipped with a horizontal straightening roller 2b has a roller mounting sleeve 3c2 at its end near the profile channel 1a. The shaft of each horizontal straightening roller 2b is rotatably mounted on the corresponding roller mounting sleeve 3c2; the shaft of each vertical straightening roller 2a is coaxially and rotatably inserted into the end of the corresponding worm gear 3c near the profile channel 1a. The installation method of the horizontal straightening roller 2b and the vertical straightening roller 2a is stable and reliable.

[0027] The working process of this utility model is as follows:

[0028] 1. After profile B is extruded from the die by the aluminum profile extrusion press, it is conveyed to the profile channel 1a by the fixed rollers on the sliding roller table;

[0029] 2. Tighten the adjusting nut 5, and the screw 6 will drive the base 3a to slide along the base slide rail 1e, thereby moving the vertical plane straightening roller 2a and the horizontal plane straightening roller 2b to the appropriate position.

[0030] 3. Based on the deformation range of profile B, turn handle 3e to adjust worm gear 3c to a suitable height so that vertical plane straightening roller 2a and horizontal plane straightening roller 2b contact the surface of profile B;

[0031] 4. According to the specifications and dimensions of profile B, continue to adjust the worm gear 3c through handle 3e so that the vertical plane straightening roller 2a and the horizontal plane straightening roller 2b apply compressive stress to the profile B to squeeze and reset it;

[0032] 5. After the positions of all vertical plane straightening rollers 2a and horizontal plane straightening rollers 2b are confirmed, the worm gear 3c is then fixed by tightening the locking bolts 3f.

[0033] 6. After extrusion, adjust the worm gear 3c by using handle 3e to move the vertical plane straightening roller 2a and the horizontal plane straightening roller 2b away from the profile B.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
