DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 A metal bending device in this embodiment includes a box body 1, and the inner bottom wall of the box body 1 is movably connected with a collection box 7. When the workpiece is bent, the waste chips generated by the bending will fall into the collection box 7 for collection, avoiding the need for secondary cleaning. Four bases 8 are fixed to the bottom of the box body 1, and two placement components for supporting the workpiece are fixed to the inner bottom wall of the box body 1. The placement components are composed of two fixing springs 2 and a stabilizing plate 3. The two fixing springs 2 are fixed to the inner bottom wall of the box body 1, and the stabilizing plate 3 is connected to the two The top of a fixing spring 2 is fixed, and an inner bottom wall of the box body 1 is provided with a movable groove adapted to the stabilizing plate 3. A rubber pad is fixed on the top of the stabilizing plate 3. The rubber pad can increase the friction between the stabilizing plate 3 and the workpiece, so that the workpiece will not be offset during bending, so as to ensure the stability of the workpiece during bending. A working box 4 is fixed on the inner top wall of the box body 1, and a pressing mechanism 5 that penetrates the inner cavity of the box body 1 is fixed to the inner cavity of the working box 4. The pressing mechanism 5 can press the workpiece down and fix it, and a bending component 6 for bending the workpiece is fixed to the bottom of the working box 4.

[0023] In this embodiment, after the workpiece is clamped and fixed by the pressing mechanism 5 and the stabilizing plate 3, the workpiece is bent by the bending assembly 6, thereby achieving a good fixing effect and making the bending process more stable.

[0024] See also Figure 3-4 In order to achieve a good fixing effect, the pressing mechanism 5 in this embodiment includes a servo motor 501 fixed to the inner bottom wall of the working box 4, and the output shaft of the servo motor 501 is fixed with a driving gear 502. A rotating shaft 503 located on the right side of the driving gear 502 is rotatably connected between the front and rear side walls of the working box 4. The rotating shaft 503 is rotatably connected to the inner cavity of the working box 4 through a bearing, and a driven gear 504 meshing with the driving gear 502 is fixed to the outer surface of the rotating shaft 503. Two fixing components 505 that penetrate the inner cavity of the box body 1 are fixed to the top of the working box 4, and a movable hole for the fixing component 505 to move is opened at the bottom of the working box 4. The normal operation of the fixing component 505 can be guaranteed by opening the movable hole, and the fixing component 505 will not be disturbed by the working box 4 during the movement, thereby affecting the normal use of the device.

[0025] It should be noted that the two fixed components 505 are composed of a guide rod 5051, a telescopic rod 5052, a tooth plate 5053 and a pressure plate 5054. The guide rod 5051 is fixed to the inner top wall of the working box 4. The guide rod 5051 can limit the moving direction of the tooth plate 5053 so that the tooth plate 5053 can only be driven to move up and down, preventing the tooth plate 5053 from being driven to rotate when it is engaged with the driving gear 502. The tooth plate 5053 is movably connected to the outer surface of the guide rod 5051, and the two tooth plates 5053 are respectively engaged with the driving gear 502 and the driven gear 504. The telescopic rod 5052 is fixed to the inner top wall of the box body 1, and the pressure plate 5054 is fixed to the tooth plate 5053 and the bottom of the telescopic rod 5052.

[0026] It can be understood that the telescopic rod 5052 is composed of a sleeve rod and a moving rod. The sleeve rod is fixed to the top of the pressure plate 5054, and the moving rod is fixed to the top of the working box 4. One end of the moving rod passes through and extends to the inside of the sleeve rod. One end of the outer side of the moving rod is fixedly connected to a first limit block located inside the sleeve rod. A first through hole compatible with the moving rod is provided on one side of the sleeve rod. By providing the first limit block, the moving rod is prevented from being separated from the sleeve rod during movement.

[0027] In this embodiment, the driving gear 502 and the driven gear 504 rotate in opposite directions, driving the two tooth plates 5053 to descend at the same time and driving the pressure plate 5054 to move toward the workpiece, and finally pressing down to clamp the workpiece, achieving the purpose of good fixing effect and more stable during bending.

[0028] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0029] The working principle of the above embodiment is:

[0030] The workpiece is placed parallel to the two stabilizing plates 3 so that the bending point of the workpiece is located directly below the bending assembly 6. The servo motor 501 is then started. The output shaft of the servo motor 501 rotates while driving the driving gear 502 to start rotating. The driving gear 502 meshes with the driven gear 504 while rotating, and drives the rotating shaft 503 to start rotating. At this time, the driving gear 502 meshes with the driven gear 504 and rotates in opposite directions. When rotating, it meshes with the two tooth plates 5053 at the same time. Since the tooth plates 5053 are restricted by the guide rods 5051, The tooth plate 5053 can only be driven to move vertically up and down. When moving, the tooth plate 5053 will drive the pressure plate 5054 to move downward. At the same time, the pressure plate 5054 is restricted by the telescopic rod 5052. When the pressure plate 5054 is driven to contact the top of the workpiece, it continues to move. When the fixing spring 2 is squeezed, the downward pressure stops. The fixing spring 2 pushes the stabilizing plate 3 upward to squeeze, and the pressure plate 5054 is used to clamp the workpiece, thereby completing the fixation. Subsequently, the workpiece is bent by pressing down through the bending assembly 6, thereby achieving the purpose of a good fixing effect.
