[0002] CNC bending machines are engineering machines that precisely control the bending process of metal sheets through a CNC system. They are widely used in high-precision sheet metal processing in industries such as automobiles, aerospace, and shipbuilding. They use molds to bend cold metal sheets and achieve multi-axis linkage control through a CNC system, supporting automatic angle compensation, pressure adjustment, and speed control.

[0003] The bottom of the movable beam of the CNC bending machine is equipped with a bending die. When the equipment is not in use, the movable beam of the CNC bending machine provides poor protection for the die. The bending die is exposed to the outside and is easily damaged by external factors, which will affect its strength during subsequent bending.

[0004] Therefore, a movable beam structure for a CNC bending machine is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a movable beam structure for a CNC bending machine. This structure solves the problem that when the movable beam of a CNC bending machine has a bending die installed at the bottom, the protective effect of the movable beam on the die is poor, leaving the bending die exposed and susceptible to damage from external factors, which affects its strength during subsequent bending.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a movable beam body, with a connecting seat integrally formed on the outer side of the movable beam body. An installation groove is formed at the bottom of the movable beam body. A protective mechanism is provided on the front side of the movable beam body. The protective mechanism includes a rotating shaft, a gear, a guard plate, a connecting plate, a guide groove, a fixing groove, a toothed groove, and a guide block.

A guide groove is formed on the outer side of the connecting plate. A fixing groove is formed on one side of the connecting plate. A toothed groove is formed on one side of the inner cavity of the fixing groove. A guide block is welded and fixed to the front side of the movable beam body.

[0007] Preferably, the guide block is slidably connected to the guide groove, and the inner wall of the guide groove is in contact with the outer wall of the guide block.

[0008] Preferably, the gear is placed inside the fixed groove, the gear meshes with the groove, and two rotating shafts are provided.

[0009] Preferably, a transmission mechanism is provided on the back of the movable beam body. The transmission mechanism includes a synchronous pulley, a lifting wheel, a worm gear, a fixed plate, a motor, and a worm. The other ends of the two rotating shafts are fixedly connected to synchronous pulleys, and one end of one of the rotating shafts is fixedly connected to a worm gear. A fixed plate is welded and fixed to the back of the movable beam body. A motor is fixedly connected to the top of the fixed plate. One end of the output shaft of the motor is fixedly connected to a worm gear. The lifting wheel is fixedly connected to the back of the movable beam body.

The mounting frame is fixedly connected to the back of the movable beam body, the protective cover is provided on the top of the mounting frame, and bolts are inserted through the outer side of the mounting frame.

[0013] Compared with the prior art, this utility model provides a movable beam structure for a CNC bending machine, which has the following beneficial effects:

[0014] 1. By setting up the guard plate, the bending mold at the bottom of the movable beam body can be protected when not in use. The gears on the two rotating shafts rotate and mesh with the tooth groove, driving the two connecting plates to move synchronously, thereby pushing down the guard plate, so that the guard plate protects the bending mold and prevents the bending mold from being damaged by bumps when not in use.

[0015] 2. When the guard plate needs to be moved, simply start the motor. The worm gear drives the worm wheel to rotate, which in turn drives one shaft to rotate. The two shafts are connected by a synchronous pulley and a synchronous belt to achieve synchronous rotation, which better drives the guard plate to move and achieves precise transmission.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This embodiment of a CNC bending machine movable beam structure includes a movable beam body 1, a connecting seat 2 integrally formed on the outer side of the movable beam body 1, an installation groove 3 opened at the bottom of the movable beam body 1, a protective mechanism provided on the front side of the movable beam body 1, the protective mechanism including a rotating shaft 4, a gear 5, a guard plate 6, a connecting plate 7, a guide groove 8, a fixing groove 9, a toothed groove 10, and a guide block 11, a rotating shaft 4 is rotatably connected through one side of the movable beam body 1, a gear 5 is integrally formed at one end of the rotating shaft 4, a guard plate 6 is provided on the front side of the movable beam body 1, a connecting plate 7 is integrally formed on the top of the guard plate 6, a guide groove 8 is opened on the outer side of the connecting plate 7, a fixing groove 9 is opened on one side of the connecting plate 7, a toothed groove 10 is opened on one side of the inner cavity of the fixing groove 9, and a guide block 11 is welded and fixed on the front side of the movable beam body 1.

[0024] By setting the guard plate 6, the bending mold at the bottom of the movable beam body 1 can be protected when not in use. The gears 5 on the two rotating shafts 4 rotate and mesh with the tooth groove 10, which drives the two connecting plates 7 to move synchronously, thereby pushing the guard plate 6 down, so that the guard plate 6 protects the bending mold and prevents the bending mold from being damaged by bumps when not in use.

[0025] Furthermore, the guide block 11 is slidably connected to the guide groove 8, and the inner wall of the guide groove 8 is in contact with the outer wall of the guide block 11.

[0026] Furthermore, gear 5 is placed inside the fixed groove 9, gear 5 meshes with the tooth groove 10, and there are two rotating shafts 4.

[0027] To ensure more precise transmission, a transmission mechanism is provided on the back of the movable beam body 1. The transmission mechanism includes a synchronous pulley 12, a lifting wheel 13, a worm gear 14, a fixed plate 15, a motor 16, and a worm 17. The other ends of the two rotating shafts 4 are fixedly connected to the synchronous pulley 12, and one end of one of the rotating shafts 4 is fixedly connected to the worm gear 14. A fixed plate 15 is welded and fixed to the back of the movable beam body 1. A motor 16 is fixedly connected to the top of the fixed plate 15. One end of the output shaft of the motor 16 is fixedly connected to the worm 17. The lifting wheel 13 is fixedly connected to the back of the movable beam body 1.

[0028] When the guard plate 6 needs to be moved, simply start the motor 16, which drives the worm gear 17 to rotate the worm wheel 14, thereby driving one shaft 4 to rotate. The two shafts 4 are connected by the synchronous pulley 12 and the synchronous belt to achieve the effect of synchronous rotation of the two shafts 4, which can better drive the guard plate 6 to move and achieve the effect of precise transmission. The setting of the worm gear 17 and the worm wheel 14 can play a self-locking role to prevent the shaft 4 from rotating on its own, and better fix the position of the guard plate 6. The equipment needs to be inspected and maintained regularly.

[0029] Furthermore, the two synchronous pulleys 12 are connected by a synchronous belt, and the outer side of the lifting wheel 13 is in contact with the synchronous belt.

[0030] Furthermore, the worm gear 14 is meshed with the worm 17, and a protective mechanism is provided on the back of the movable beam body 1.

[0031] Furthermore, the installation mechanism includes a mounting frame 18, a protective cover 19, and bolts 20. The mounting frame 18 is fixedly connected to the back of the movable beam body 1. A protective cover 19 is provided on the top of the mounting frame 18. Bolts 20 are inserted through the outer side of the mounting frame 18. The protective cover 19 is fixedly connected to the mounting frame 18 by bolts 20. The protective cover 19 can protect the transmission components.

[0032] The working principle of the above embodiment is as follows: When not in use, the bending mold at the bottom of the movable beam body 1 is protected by the guard plate 6. The gears 5 on the two rotating shafts 4 rotate, and the gears 5 mesh with the tooth grooves 10, driving the two connecting plates 7 to move synchronously, thus pushing down the guard plate 6. This protects the bending mold from impact damage when not in use. When the guard plate 6 needs to be moved, simply start the motor 16, which drives the worm gear 17 to rotate the worm wheel 14, thereby rotating one of the rotating shafts 4. The two rotating shafts 4 are connected by a synchronous pulley 12 and a synchronous belt, achieving synchronous rotation and better driving the guard plate 6 to move, achieving precise transmission. The worm gear 17 and worm wheel 14 also have a self-locking effect, preventing the rotating shafts 4 from rotating on their own and better fixing the position of the guard plate 6. The equipment requires regular inspection and maintenance.
