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

[0022] Example:

[0023] See also Figure 1-5 A bending device for the production of stainless steel sheet metal stamping parts includes a frame and a bending table 1 fixedly installed on the frame. The middle part of the bending table 1 is set as a stamping bending position and a bending vertical surface 2 is provided at the stamping bending position. A conveyor belt 3 with multiple sliding card slots 4 evenly distributed is provided on the bending table 1. A reciprocating bending structure is provided at the stamping bending position. The reciprocating bending structure includes a bending block 15 that can be reciprocated and a clamping mechanism. The bending block 15 is adapted to the bending vertical surface 2. The bending block 15 and the clamping mechanism are driven reciprocally up and down by a driving mechanism. It also includes two groups of bending distance adjustment structures arranged on both sides of the conveyor belt 3 at the stamping bending position.

[0024] The two eccentric wheels 11 are rotatably connected to each other on the fixed frame 10, and the eccentric sides of the two eccentric wheels 11 are provided with sliding shafts 14. The two sliding shafts 14 are sleeved with lifting bars 12. The lifting bars 12 are provided with two horizontal limit grooves 13 that slide with the sliding shafts 14 horizontally slidingly matched. The bending block 15 is fixedly installed at the bottom of the lifting bar 12. The top of the lifting bar 12 is fixedly connected with a vertical guide frame 16 that slides with the vertical guide of the frame. The pressing mechanism is fixedly installed at the bottom of the vertical guide frame 16. A driving member that drives the two eccentric wheels 11 to rotate is provided on the fixed frame 10. Through the driving member, it is easy to drive the two eccentric wheels 11 to rotate. When the two eccentric wheels 11 rotate, the lifting bar 12 is driven to lift and lower back and forth. Through the cooperation of the horizontal limit grooves 13, the sliding shafts 14 and the vertical guide frame 16, the lifting bar 12, the bending block 15 and the pressing mechanism can perform vertical lifting movement as a whole.

[0025] Specifically, the driving component includes a bending motor 17 fixedly mounted on the fixed frame 10. The output shaft of the bending motor 17 is connected to the two eccentric wheels 11 through a synchronous belt 18. In addition, the fixed frame 10 is also rotatably connected to two guide wheels 19 that slide and cooperate with the synchronous belt 18. When the bending motor 17 is started, the two eccentric wheels 11 are driven to rotate simultaneously through the cooperation of the synchronous belt 18 and the guide wheel 19.

[0026] Specifically, the clamping mechanism includes a top plate 20 fixedly mounted on the bottom of the vertical guide frame 16, and a plurality of sliding columns 22 are vertically slidably fitted on the top plate 20, a pressure plate 21 is fixedly mounted on the bottom of the plurality of sliding columns 22, and a limiting block 24 is fixedly mounted on the top of the plurality of sliding columns 22, and a spring 23 is sleeved on the plurality of sliding columns 22, and the two ends of the spring 23 are respectively fixedly connected to the top plate 20 and the pressure plate 21. Through the elasticity of the spring 23, the pressure plate 21 is pressed when it first contacts the stainless steel sheet metal. As the stamping and bending proceeds, the top plate 20 moves downward synchronously, and then the spring 23 is further compressed, thereby ensuring the smooth progress of the stamping and bending.

[0027] Specifically, the bending and distance adjustment structure includes a mounting base 6 that can be pushed horizontally toward the side of the conveyor belt 3. The mounting base 6 is connected to a limiting roller 7 that rotates toward the upper side of the conveyor belt 3. The mounting base 6 is fixedly connected to the frame through a driving cylinder 8. A guide column 9 that slides horizontally with the frame is fixedly installed on the mounting base 6. By extending and retracting the output shaft of the driving cylinder 8, the mounting base 6 can be fed toward the side of the conveyor belt 3, thereby facilitating the limiting of the stainless steel sheet metal workpiece by the limiting roller 7. The setting of the guide column 9 facilitates the guidance of the mounting base 6 and increases the stability of the bending and distance adjustment.

[0028] Specifically, a conveyor motor 5 for driving the conveyor belt 3 to rotate is fixedly mounted on the frame. By starting the conveyor motor 5, the conveyor belt 3 can be driven to rotate.

[0029] During use, the conveyor belt 3 is started, and stainless steel sheet metal workpieces are continuously placed into multiple slide troughs 4 from one side of the conveyor belt 3. When the stainless steel sheet metal workpiece on the front side moves to the stamping and bending position, the distance of the stainless steel sheet metal workpiece extending out of the bending facade 2 can be adjusted by two bending distance adjustment structures. Then the driving mechanism drives the bending block 15 and the clamping mechanism to press down and move up and down at the same time. While pressing down, the stainless steel sheet metal workpiece is first pressed, and the stainless steel sheet metal workpiece is stamped and bent through the cooperation of the bending block 15 and the bending facade 2. Then, as the conveyor belt 3 is conveyed, the stainless steel sheet metal stamping parts after bending and stamping automatically fall out from the other side.
