Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a CNC bending machine for aluminum plate processing that can be quickly positioned. Background Technology

[0002] A CNC bending machine is essentially a CNC bending machine mold used to bend thin plates.

[0003] A search revealed Chinese patent CN207577169U, which discloses a CNC bending machine for rapid positioning in aluminum plate processing. The machine includes a base plate, a positioning component fixedly mounted on the top of the base plate, a sleeve rod fitted on the top of the positioning component, a housing fixedly mounted on the outer side of the positioning component, clamping blocks fixedly mounted on both sides of the housing, a connecting piece fixedly mounted on the top of the housing with one end at the top of the clamping block, a screw threaded through the top of the connecting piece, guide rails fixedly mounted on the front and back surfaces of the housing, a limit sleeve fixedly mounted on the end of the guide rail away from the housing, a slider movably mounted on the top of the guide rail, a positioning rod fixedly mounted on the top of the slider, clamping blocks fixedly mounted on both ends of the positioning rod, and metal rods fixedly mounted on both sides of the housing.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Most existing bending devices are relatively simple. During use, the stretching at the outer bending point and the compression at the inner bending point of the aluminum plate often cause the bending line of the aluminum plate to deviate, thereby reducing the efficiency of the bending device. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a CNC bending machine for aluminum plate processing with rapid positioning capability. Activating the hydraulic telescopic rod moves the mounting plate downwards, causing the rack on the connecting block to move downwards, and simultaneously moving the fixing plate on the telescopic rod downwards, thus positioning the aluminum plate and preventing movement during bending. Simultaneously, the rack's movement causes gear one to rotate clockwise, which in turn causes gear two on the rotating shaft to rotate counterclockwise. Since gear two and gear three mesh, they cause the rotating rod on gear three to rotate clockwise, thereby causing the bending plate on the mounting block to bend the aluminum plate. After bending, the hydraulic telescopic rod retracts, resetting the bending plate for easy reuse.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a CNC bending machine for aluminum plate processing with rapid positioning, including a desktop, a fixed frame fixedly connected to the top of the desktop, a hydraulic telescopic rod installed on the top of the fixed frame, an installation plate fixedly connected to the output end of the hydraulic telescopic rod, and connecting blocks fixedly connected to both sides of the installation plate, with racks fixedly connected to the bottom of the two connecting blocks, a rotating shaft 1 and a rotating shaft 2 rotatably connected to the inner walls of both sides of the desktop, a gear 1 and a gear 2 keyedly connected to the two rotating shafts 1 and 2 respectively, the gears 1 and 2 meshing, a rotating rod rotatably connected to both inner walls of the desktop, two gears 3 keyedly connected to the rotating rod, the gears 3 and 2 meshing, two installation blocks fixedly connected to the outer circumference of the rotating rod, and a bending plate fixedly connected to the top of the two installation blocks.

[0008] In some embodiments, the mounting bracket is U-shaped.

[0009] In some embodiments, two telescopic rods are fixedly connected to the bottom of the mounting plate, and the bottom ends of the two telescopic rods are jointly fixedly connected to a fixing plate.

[0010] In some embodiments, each of the two telescopic rods is fitted with a telescopic spring, and the two ends of the telescopic spring are respectively fixedly connected to the telescopic rod and the fixed plate.

[0011] In some embodiments, a feeding plate is fixedly connected to the top of the desktop, and the feeding plate is located below the fixed plate.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] This invention places an aluminum plate on a feeding plate and a bending plate, then activates a hydraulic telescopic rod to move the mounting plate downwards, which in turn moves the rack on the connecting block downwards and the fixing plate on the telescopic rod downwards, positioning the aluminum plate and preventing it from shifting during bending. Simultaneously, the rack's movement causes gear one to rotate clockwise, which in turn causes gear two on the rotating shaft to rotate counterclockwise. Since gear two and gear three mesh, the rotating rod on gear three rotates clockwise, which in turn causes the bending plate on the mounting block to bend the aluminum plate. After bending, the hydraulic telescopic rod retracts, resetting the bending plate for reuse. This invention facilitates quick positioning and fixing of the aluminum plate while simultaneously bending it, improving the device's efficiency.

[0014] This invention addresses the problem that most existing bending devices are relatively simple, and during use, the stretching at the outer bend of the aluminum plate and the compression at the inner bend often cause the bending line of the aluminum plate to deviate, thus reducing the efficiency of the bending device.

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides an improved CNC bending machine for aluminum plate processing with rapid positioning capability. The technical solution of this utility model is as follows:

[0023] like Figures 1-3As shown, a CNC bending machine for rapid positioning of aluminum plates includes a desktop 1, a fixed frame 2 fixedly connected to the top of the desktop 1, a hydraulic telescopic rod 3 mounted on the top of the fixed frame 2, a mounting plate 4 fixedly connected to the output end of the hydraulic telescopic rod 3, and connecting blocks 8 fixedly connected to both sides of the mounting plate 4. A rack 9 is fixedly connected to the bottom of each of the two connecting blocks 8. A rotating shaft 12 and a rotating shaft 13 are rotatably connected to the inner walls of both sides of the desktop 1, respectively. A gear 18 and a gear 14 are keyed to both rotating shafts 12 and 13, respectively, and the gears 18 and 14 mesh with each other. A rotating rod 15 is rotatably connected to the inner walls of both sides of the desktop 1. Two gears 16 are keyed to the rotating rod 15. Gears 16 mesh with gears 14. Two mounting blocks 17 are fixedly connected to the outer circumference of the rotating rod 15. A bending plate 11 is fixedly connected to the top of the two mounting blocks 17. When the hydraulic telescopic rod 3 is activated, the mounting plate 4 moves downward, which in turn moves the rack 9 on the connecting block 8 downward. The movement of the rack 9 causes gear 18 to rotate, which in turn causes gear 14 on the rotating shaft 13 to rotate, which in turn causes the rotating rod 15 on gear 16 to rotate, which in turn causes the bending plate 11 on the mounting block 17 to bend the aluminum plate. The bending plate 11 facilitates the bending of the aluminum plate.

[0024] like Figure 1 As shown, in one embodiment, the mounting bracket 2 is U-shaped; the U-shaped design facilitates the installation of components within the device.

[0025] like Figure 1 As shown, in one embodiment, two telescopic rods 5 are fixedly connected to the bottom of the mounting plate 4, and a fixing plate 6 is fixedly connected to the bottom end of the two telescopic rods 5. The fixing plate 6 facilitates downward pressing and fixing of the aluminum plate.

[0026] like Figure 2 As shown, in one embodiment, a telescopic spring 7 is sleeved on each of the two telescopic rods 5, and the two ends of the telescopic spring 7 are fixedly connected to the telescopic rod 5 and the fixed plate 6 respectively; the setting of the telescopic spring 7 facilitates the reciprocating motion of the fixed plate 6.

[0027] like Figure 2 As shown, in one embodiment, a feeding plate 10 is fixedly connected to the top of the desktop 1, and the feeding plate 10 is located below the fixed plate 6; the feeding plate 10 facilitates the placement of aluminum plates.

[0028] The specific working method is as follows: When in use, place the aluminum plate on the feeding plate 10 and the bending plate 11, then start the hydraulic telescopic rod 3 to drive the mounting plate 4 to move downward, drive the rack 9 on the connecting block 8 to move downward, and at the same time drive the fixing plate 6 on the telescopic rod 5 to move downward, positioning the aluminum plate and preventing it from moving during bending. At the same time, the movement of the rack 9 drives the gear 18 to rotate clockwise, driving the gear 14 on the rotating shaft 13 to rotate counterclockwise. Since the gear 14 and the gear 16 mesh, the rotating rod 15 on the gear 16 rotates clockwise, thereby driving the bending plate 11 on the mounting block 17 to bend the aluminum plate. After bending, the hydraulic telescopic rod 3 retracts to reset the bending plate 11, which is easy to reuse. This achieves quick positioning and fixing of the aluminum plate, while bending the aluminum plate, improving the efficiency of the device.

[0029] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
