DETAILED DESCRIPTION
[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0023] like Figure 1-Figure 3 As shown, an aluminum tube bending device that is convenient for controlling the bending angle includes a workbench 1, a cylinder 101 and a top block 102, the cylinder 101 is fixedly assembled on the upper side of the workbench 1, the top block 102 is fixedly assembled on the working part of the cylinder 101, two slide grooves 103 located in the same straight line are symmetrically arranged in the middle of the workbench 1, the workbench 1 is assembled and connected with a slide rod 104 in the slide groove 103, the slide rod 104 is slidably connected with two sliders 105, a working groove 106 is opened on one side of the slide groove 103, a limiting mechanism is hinged on one side of the two sliders 105, the limiting mechanism is located on one side of the working groove 106, the limiting mechanism is used to limit the sliders 105 to move the same distance inward or outward at the same time and keep the two sliders 105 symmetrically arranged, a rotating seat 107 is rotatably connected to the upper side of the slider 105, a rotating connection mechanism is provided between the rotating seat 107 and the slider 105, and a positioning mechanism is provided above the rotating seat 107;
[0024] The positioning mechanism includes an arc groove 201 , a positioning cover 202 and a bolt 203 . The arc groove 201 is provided on the upper side of the rotating seat 107 , and the positioning cover 202 and the rotating seat 107 are connected by the bolt 203 .
[0025] The technical solution of this embodiment is adopted, and the working groove 106 is used to make the limiting mechanism slide in the working groove 106 of the workbench 1. When working, the aluminum tube is first placed in the arc groove 201 of the positioning mechanism, and then the position to be bent is aligned with the middle of the top block 102, and then the bolt 203 is tightened to fix the aluminum tube in the arc groove 201 and the positioning cover 202. The extension length of the cylinder 101 is calculated according to the angle at which the aluminum tube is to be bent, so as to control the extension of the cylinder 101. During the extension process of the cylinder 101, the relative position of the aluminum tube and the rotating seat 107 remains unchanged, and the rotating seat 107 deflects with the aluminum tube as the aluminum tube is bent. At the same time, the rotating seat 107 slides toward the middle, and the slider 105 slides on the slide rod 104. The limiting mechanism ensures that the slider 105 slides toward the middle, so that the bending position of the aluminum tube will not be offset.
[0026] Reference Figure 1 : The limiting mechanism includes two connecting rods 301, a movable seat 302 and a limiting bar 303. The connecting rod 301 is hinged between the slider 105 and the movable seat 302. The movable seat 302 and the top block 102 are located on the same straight line. The two connecting rods 301 are arranged symmetrically. The limiting bar 303 is located on both sides of the movable seat 302, and the limiting bar 303 is fixedly connected to the workbench 1.
[0027] In this embodiment, the moving seat 302 moves vertically in the limit bar 303. When the slider 105 moves, it also drives the connecting rod 301 to move, and the connecting rod 301 drives the moving seat 302 to move. Since the moving seat 302 moves on the center line, the two connecting rods 301 are symmetrically arranged and have the same length. Therefore, when the moving seat 302 moves, it in turn acts on the connecting rod 301, so that the connecting rod 301 drives the slider 105 to move the same distance inward or outward at the same time.
[0028] Reference Figure 2-Figure 3 : The rotating connection mechanism includes a rotating shaft 401, a threaded rod 402, a nut 403 and a nut groove 404. The rotating shaft 401 is fixedly connected to the upper side of the slider 105, the threaded rod 402 is vertically arranged above the rotating shaft 401, the nut 403 is threadedly connected to the threaded rod 402, the nut groove 404 is opened on the upper side of the rotating seat 107, the nut 403 is located in the nut groove 404, and the rotating seat 107 is rotatably connected to the rotating shaft 401.
[0029] In this embodiment, the nut 403 is located in the nut groove 404, which prevents the nut 403 from directly contacting the outside and thus becoming loose.
[0030] Reference Figure 2-Figure 3 : A push block 501 is fixedly connected to the lower side of the top block 102, the upper side of the movable seat 302 is flush with the lowest point of the arc groove 201, the side of the push block 501 abuts against the side of the movable seat 302, and the upper side of the push block 501 is flush with the upper side of the movable seat 302.
[0031] In this embodiment, the push block 501 is used to push the moving seat 302 to move, to prevent the moving seat 302 from being stuck when the connecting rod 301 drives the moving seat 302 to move. In this case, the top block 102 pushes the aluminum tube and the moving seat 302 to move at the same time.
[0032] Reference Figure 3 A positioning groove 502 is provided in the middle of the push block 501, and the positioning groove 502 and the cylinder 101 are located on the same straight line.
[0033] In this embodiment, the positioning groove 502 is used to facilitate the alignment of the bending position of the aluminum material with the positioning groove 502, thereby facilitating the bending of the aluminum material without aligning the bending position with the middle of the top block, thereby reducing the difficulty of alignment.
[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
