[0027] Please refer to Figures 1-5 The utility model provides an embodiment: an automatic deburring household electrical appliance sheet metal part stamping die, including fixed disc 111, the fixed disc 111 below fixedly arranged with support seat 117, and support seat 117 one side top vertical setting has stamping part 110, the fixed disc 111 top rotation setting has rotating disc 112; turnover assembly 200, turnover assembly 200 ring type evenly distributes in rotating disc 112 top, wherein one turnover assembly 200 sets up just below stamping part 110, rotating disc 112 away from stamping part 110 forty-five degree direction setting has edge removing device 120, turnover assembly 200 includes rectangular die 210, rectangular die 210 one side setting has L bracket 211, two L bracket 211 inside rotation setting has movable template 212, movable template 212 bottom and rectangular die 210 parallelly and closely, L bracket 211 one side setting has driving motor 214, for driving movable template 212 overturn, edge removing device 120 front setting has controller, edge removing device 120 top setting has polishing part 122, edge removing device 120 inside setting has conveying belt 121;

[0028] For conveying sheet metal parts, the stamping part 110 moves downward, cooperates with the movable template 212, and can quickly complete stamping. The punch hole below the sheet metal part forms burrs. The driving motor 214 is set to start rotating one hundred and eighty degrees in advance, drives the sheet metal part inside the movable template 212 to overturn and fall off. The fallen sheet metal part falls onto the conveying belt 121 above the burr removing device 120. At this time, the burrs of the sheet metal part are upward, and the conveying belt 121 drives the sheet metal part to be conveyed to the polishing part 122 inside. The polishing part 122 directly polishes the burrs from above, which can realize the coherent connection of the stamping and burr removing processes, reduce the sheet metal part circulation time, speed up the overall production rhythm, reduce the labor cost and time cost of separately collecting and transporting the burr removing sheet metal parts, improve the production efficiency, and accurately remove the burrs to help ensure the size accuracy of the sheet metal parts and meet the subsequent assembly and other use requirements;

[0029] The rotating disc 112 is connected with the indexing rotary cylinder 115 below, and the indexing rotary cylinder 115 indexes the rotation angle by forty-five degrees. The rotating disc 112 ensures that each overturning assembly 200 rotates at a directional angle. After each stamping, it is directly rotated by forty-five degrees to overturn and enter above the burr removing device 120, ensuring that the feeding, stamping, and overturning continue to proceed.

[0030] Further, the movable template 212 is internally provided with a discharging punch hole 213, the rectangular die 210 is internally provided with a hole groove, the fixed disc 111 is internally provided with a discharging groove 116, and the discharging groove 116 and the rectangular die 210 are internally connected, and the supporting seat 117 is provided with a guide groove 114 on one side. The guide groove 114 is arranged below the discharging groove 116 and is inclined downward to the outside. After stamping, the waste falls downward through the discharging punch hole 213, and finally falls onto the guide groove 114 through the rectangular die 210 and the discharging groove 116 inside. The sheet metal part is affected by the inclination angle of the guide groove 114, and finally slides and collects to produce waste on one side.

[0031] Further, the rotating disc 112 is provided with a power slip ring 113 at the top center, which provides power for the driving motor 214. In the rotating state, it remains relatively static to provide energy for the driving motor 214.

[0032] In summary, the automatic deburring household appliance sheet metal stamping die disclosed in the embodiments of the present application can quickly complete stamping by the cooperation of the stamping part 110 and the movable die plate 212 when in use, and the punch hole below the sheet metal forms burrs, the driving motor 214 is set to start rotating 180 degrees in advance to drive the sheet metal inside the movable die plate 212 to overturn and fall off, the fallen sheet metal falls onto the conveying belt 121 above the edge removing device 120, the burrs of the sheet metal are upward at this time, the conveying belt 121 drives the sheet metal to be conveyed to the polishing part 122, and the polishing part 122 directly polishes the burrs from above. After stamping, the waste falls downward through the blanking punch hole 213, and finally falls into the guide chute 114 through the rectangular die 210 and the discharge chute 116, and the sheet metal is affected by the inclination angle of the guide chute 114 and finally slides to one side to collect and generate waste.
