Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending machine technology, specifically to an aluminum alloy profile bending machine. Background Technology
[0002] A bending machine is a type of metal processing machinery primarily used to plastically deform metal sheets, strips, tubes, or other metal profiles under pressure, thereby forming specific angles and shapes. Bending machines are widely used in manufacturing, particularly in metal structures, shipbuilding, automotive, aerospace, construction, furniture, and many other industries, where they are indispensable equipment.
[0003] When using a bending machine, short sheets can be bent by hand. However, for longer sheets, which are typically metal and possess excellent flexibility, manual handling only allows gripping of the edges. Without support, the sheet will bend, making it difficult to align the edges with the bending cutter. Therefore, we propose an aluminum alloy profile bending machine. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical scheme of the utility model will be described clearly and completely below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0022] Referring to Figures 1 to 6 , the utility model provides a kind of technical scheme: a kind of aluminum alloy profile bending machine, including rack 1, rack 1 top is equipped with mounting beam 12, first telescopic mechanism 11 is equipped in the middle part of mounting beam 12 vertically downwards, first telescopic mechanism 11 bottom is connected with mounting frame body 9, and mounting frame body 9 is horizontally arranged;
[0023] Bending cutter 8 is installed below mounting frame body 9, and bending cutter 8 can be a plurality of interval setting cutter, of course, it can also be an integral cutter, forming die 5 is equipped below bending cutter 8, and forming die 5 bending cutter 8 matching and is installed on rack 1, and mounting frame body 9 is driven to realize up and down by first telescopic mechanism 11, so that bending cutter 8 is placed in forming die 5 or elevated to above forming die 5;
[0024] As Figure 1 And Figure 2As shown, in order to make the mounting frame body 9 more stable, a guide mechanism is arranged at both ends of the mounting frame body 9, which includes a first guide rail 10 arranged on both sides of the rack 1, the first guide rail 10 is perpendicular to the mounting frame body 9, and the two ends of the mounting frame body 9 are slidably arranged on the first guide rail 10 through a sliding block, so that the two ends of the mounting frame body 9 can be supported by the first guide rail 10.
[0025] Further, as shown in Figure 1 and Figure 2 , a support frame 7 is arranged on one side of the forming die 5, which is located outside the rack 1, and the side of the support frame 7 close to the forming die 5 is rotatably connected with the rack 1. The specific installation method is as follows, as shown in Figure 1 and Figure 4 , both ends of the support frame 7 are provided with a support arm 3 extending towards the forming die 5, and a rotating shaft 14 parallel to the forming die 5 is arranged at the end of each support arm 3. During installation, the rotating shaft 14 is rotatably arranged in the support base 2, and then the two support bases 2 are arranged at both ends of the forming die 5, and finally the support bases 2 are arranged on the rack 1;
[0026] Then, a placing plate 6 is arranged on the top of the support frame 7, as shown in Figure 1 , when the placing plate 6 is horizontally placed, the placing plate 6 is flush with the surface of the forming die 5. The bottom of the support frame 7 is provided with a telescopic driving device, as shown in Figure 4 , which includes a driving seat 19 arranged below the support frame 7, and the bottom of the driving seat 19 is rotatably connected with a second telescopic mechanism 13, and the bottom of the second telescopic mechanism 13 is rotatably arranged on a support beam 4, and the two ends of the support beam 4 are fixed with the rack 1. Under the driving of the telescopic driving device, the placing plate 6 rotates around the forming die 5, that is, when the second telescopic mechanism 13 telescopes, it drives the support frame 7 to rotate, thereby driving the placing plate 6 to rotate. The driving seat 19 vertically extends downward, which can increase the upward stroke of the second telescopic mechanism 13;
[0027] It should be noted that the rotating shaft 14 is coaxially arranged with the forming die 5, so that the placing plate 6 can rotate around the forming die 5 when the placing plate 6 rotates. As shown in Figure 6 , in actual use, the plate material (such as Figure 6 indicated by arrow A) needed to be folded is placed on the placing plate 6, the edge of the plate material is placed on the top of the forming die 5, and then the first telescopic mechanism 11 is controlled to drive the press-bending cutter 8 to descend, so that the edge of the plate material is pressed into the forming die 5, thereby bending the edge of the plate material;
[0028] But because the length of the plate is long, in order to avoid the deformation of the plate in the pressing process, the placement plate 6 at this time highlights its role, that is, the placement plate 6 is driven by the second telescopic mechanism to rotate with the plate when the edge is bent, that is, the placement plate 6 and the plate rotate synchronously, when the plate is bent, the placement plate also rotates with the plate, as shown in Figure 6 , so that the rotating plate is always placed on the surface of the placement plate 6, so that the plate can be supported, preventing the edge of the placement plate 6 from deforming.
[0029] Further, as shown in Figure 3 , the forming die 5 away from the support frame 7 side is provided with a material blocking mechanism, the material blocking mechanism includes a linear drive module 17 vertically arranged with the forming die 5, the linear drive module 17 top is provided with a strip-shaped seat 18 parallel to the forming die 5, the strip-shaped seat 18 top is provided with a baffle 15, the baffle 15 and the forming die 5 are parallel;
[0030] The strip-shaped seat 18 bottom is slidably installed on the second guide rail 16 through the sliding block, the second guide rail 16 is parallel to the linear drive module 17, the second guide rail 16 and the linear drive module 17 are both installed on the top of the rack 1. The linear drive module 17 can drive the baffle 15 to move closer to or away from the forming die 5, thereby changing the distance between the baffle 15 and the forming die 5. After the plate is placed on the placement plate 6, the side edge of the plate is first abutted against the baffle 15, at which time the plate can be edge-bent, and the baffle 15 plays a positioning role.
[0031] Based on the above embodiment, as shown in Figure 4 , an angle sensor 20 is arranged at the end of one of the rotating shafts 14, the angle sensor 20 is arranged on the rack 1 through a sensor support, the angle sensor 20 is connected with a controller, and the controller is connected with the first telescopic mechanism 11, the second telescopic mechanism 13 and the linear drive module 17 respectively;
[0032] The controller is a PLC logic controller or a host computer. The controller can control each component to operate according to the set steps, thereby realizing intelligent control. Because the edge-bending operation must be performed according to specific steps each time, under the control of the controller, the baffle 15 is driven by the linear drive module 17 to control the distance between the baffle 15 and the forming die 5 according to the edge-bending steps, so that the plate can be positioned each time when the plate abuts against the baffle 15;
[0033] Because the bending angle of the plate is fixed each time, the angle sensor 20 can monitor the rotation angle of the placement plate 6 in real time, so that the placement plate 6 can hold the plate each time during the edge-bending operation, and the plate is always uniformly stressed.
[0034] Based on the above embodiments, it needs to be further explained that the first telescopic mechanism 11 and the second telescopic mechanism 13 are both hydraulic cylinders, and the linear drive module 17 is a belt linear drive module, a lead screw linear drive module or a linear motor.
[0035] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
