[0001] The application relates to the field of bending machines, in particular to a feeding structure of a numerical control plate bending machine. BACKGROUND

[0002] The numerical control plate bending machine is a device for accurately bending metal plates by using digital control technology, which is mainly used for bending various metal plates (such as steel plates, aluminum plates, copper plates, etc.) according to the pre-set angle, length and shape. Through accurate control of the bending process, various complex sheet metal structures such as case shells, automobile parts and industrial equipment shells can be manufactured.

[0003] When the existing plate is fed to the bending position of the bending machine, the plate is generally supported by a support, and the plate is pushed to move along the upper surface of the support into the bending machine. However, when some plates are subjected to multi-angle bending processing, the placement position of the plate needs to be manually adjusted, so that the plate is placed in the bending machine in different directions, which makes the operation time-consuming and laborious, and affects the overall processing efficiency of the plate, thereby increasing the overall processing time of the plate.

[0004] For the above-mentioned related technology, the inventor believes that the plate bending process has the defect that the plate placement angle is not convenient to adjust, therefore, a feeding structure of a numerical control plate bending machine is proposed to solve the above problems.

DETAILED DESCRIPTION

[0018] The following will be described in detail in combination with the drawings Figs. 1-3 The application will be further described in detail.

[0019] This application discloses a feeding structure for a CNC sheet metal bending machine. (Refer to...) Figs. 1-3 A feeding structure for a CNC sheet metal bending machine includes a feeding bracket 1. A support plate 5 is fixedly installed at the bottom of the feeding bracket 1. An electric telescopic rod 6 is provided at the top center of the support plate 5. A connecting plate 7 is installed at the output end of the upper surface of the electric telescopic rod 6. A grooved wheel 8 is rotatably installed on the top edge of the connecting plate 7. Several limiting slots 9 are opened on the outer surface of the grooved wheel 8. A placement plate 10 is welded to the upper surface of the limiting slots 9. A support frame 11 is fixedly installed at the bottom edge of the connecting plate 7. A servo motor 12 is installed inside the support frame 11. A movable support plate 13 is installed above the connecting plate 7 at the output end of the upper surface of the servo motor 12. A limiting lever 14 is welded to the top edge of the movable support plate 13. The outer diameter of the limiting lever 14 is smaller than the distance between the two sides of the inner wall of the limiting slot 9. One side of the outer surface of the limiting lever 14 is located inside the limiting slot 9. The limiting slot 9 and the limiting lever 14 are engaged with each other. A guide component is also provided on the upper surface of the support plate 5, which also provides guidance and support for the placement plate 10.

[0020] By activating the electric telescopic rod 6, the placement plate 10 is moved upward, allowing it to pass between the two fixed plates 3, thereby lifting the sheet material. Simultaneously, the servo motor 12 is activated to drive the movable support plate 13 to rotate. This rotation causes the limit lever 14 to rotate circumferentially, allowing the limit lever 14 to engage with the limit slots 9 at different positions. This causes the limit lever 14 to drive the grooved wheel 8 to rotate intermittently, which in turn causes the intermittently rotating placement plate 10 to adjust the angle of the sheet material on its upper surface. This allows different sides of the sheet material to be placed inside the bending machine for processing, demonstrating the angle adjustment effect of the sheet material during bending.

[0021] Reference Fig. 2 The guide assembly includes a guide bracket 15, which is fixedly installed on the upper surface of the support plate 5 near the outer surface of the electric telescopic rod 6. A guide groove 16 is provided at the top edge of the guide bracket 15. Several guide support plates 17 are welded to the bottom edge of the placement plate 10 into the guide groove 16. The cross-section of the guide support plate 17 is an arc structure. The bottom of one side of the guide support plate 17 is located inside the guide groove 16. The guide groove 16 and the guide support plate 17 are interlocked.

[0022] By causing the rotating placement plate 10 to move along the inside of the guide groove 16, the guide bracket 15 supports the moving guide bracket 17, keeping the placement plate 10 in a stable state during movement, thus demonstrating the support effect of the guide bracket 15 on the placement plate 10.

[0023] Reference Fig. 1 and Fig. 2Several long support rollers 2 are rotatably installed on the top of the feeding bracket 1. Fixed plates 3 are symmetrically fixed on the top of the feeding bracket 1. Several short support rollers 4 are rotatably installed between the feeding bracket 1 and the fixed plates 3. By placing the processed board on the upper surface of the feeding bracket 1, the board is pushed to move along the upper surfaces of the long support rollers 2 and the short support rollers 4, so that the long support rollers 2 and the short support rollers 4 move the board above the placement plate 10, demonstrating the supporting effect of the long support rollers 2 and the short support rollers 4 on the board.

[0024] The implementation principle of the feeding structure of a CNC sheet metal bending machine according to an embodiment of this application is as follows: The sheet metal to be processed is placed on the upper surface of the feeding bracket 1, and the sheet metal is pushed along the upper surfaces of the long support roller 2 and the short support roller 4 to a position above the placement plate 10. The electric telescopic rod 6 is activated to move the placement plate 10 upwards, allowing it to pass between the two fixed plates 3, thereby lifting the sheet metal. Simultaneously, the servo motor 12 is activated to rotate the movable support plate 13, causing the movable support plate 13 to rotate and drive the limit lever 14 to rotate circumferentially. The limit card is inserted into the limit card slot 9 at different positions, causing the limit lever 14 to drive the groove wheel 8 to rotate intermittently. This, in turn, causes the intermittently rotating placement plate 10 to adjust the angle of the upper surface of the sheet metal intermittently, allowing different sides of the sheet metal to be placed inside the bending machine for processing. The input terminals of the electric telescopic rod 6 and the servo motor 12 are both electrically connected to the output terminal of the external power supply. Compared with the prior art, this solution has the effect of facilitating the adjustment of the bending position when the sheet metal is loaded, improving the multi-angle processing efficiency of the sheet metal, and solving the problem of inconvenience when adjusting the placement angle of the sheet metal.
