The front end of the outer punching top block is in a right-angle triangle shape. In addition, the front end of the outer punching top block is in a right-angle triangle shape, so the outer punching top block only punches the side wall of the pot cover to form a cutting hole, and the side wall of the part of the side wall is sunk into the inner side of the pot cover, so no waste is generated, and the cutting hole is downward.
The working principle of the invention is as follows:
Before the invention starts working, the upper die and the lower die are unfolded, a worker or a robot firstly places the pot cover 4 to be punched on the top of the pot cover positioning center seat, at the moment, the outer pressing block and the inner punching pressing block are respectively positioned on the outer side and the inner side of the pot cover 4, the side wall of the pot cover 4 is positioned between the outer pressing block and the inner punching pressing block, the outer punching pressing block and the inner pressing block are respectively positioned on the outer side and the inner side of the pot cover 4, and the side wall of the pot cover 4 is also positioned between the outer punching pressing block and the inner pressing block.
Then, the worker starts the present die, the hydraulic press drives the upper die 1 to start to descend, and the plurality of punching press punches 15 and the plurality of punching press punches 14 at the bottom of the upper die simultaneously punch the respective corresponding punching driving slider 244 and punching driving slider 234, so that the punching driving slider 244 and the punching driving slider 234 move downward, and the lower ends of the punching driving slider 244 and the punching driving slider 234 are inserted into the second inclined surface push hole and the first inclined surface push hole, respectively (the third return spring and the sixth return spring are compressed).
When the punching driving slide block 234 moves downwards, the punching driving slide block 234 drives the first horizontal slide blocks 232 and the outer pressing blocks 235 of the inner punching mechanisms 23 to slide towards the direction of the pot cover positioning center seat 22, the first horizontal slide blocks drive the first sliding connecting rods to slide inwards (the first reset springs are compressed), meanwhile, the second horizontal slide blocks 233 and the inner pressing blocks 236 slide towards the direction away from the pot cover positioning center seat 22, the second horizontal slide blocks drive the second sliding connecting rods to slide outwards (the second reset springs are compressed), the outer pressing blocks press against the side wall of the pot cover 4 outside the pot cover 4, the inner pressing blocks punch the side wall of the pot cover 4 from inside to outside, the inner pressing blocks 236 punch the holes 42 on the side wall of the pot cover 4 and press into the punching yielding holes 238 of the outer pressing blocks 235, and the outer punching mechanisms simultaneously punch the holes 42 on the side wall of the pot cover 4.
Simultaneously, the punching driving sliding block 244 also moves downwards, the punching driving sliding block 234 drives the third horizontal sliding blocks 242 and the outer punching jacking blocks 246 of the outer punching mechanisms 24 to slide towards the pot cover positioning center seat 22, the third horizontal sliding blocks drive the third sliding connecting rod to slide inwards (the fourth reset spring is compressed), the fourth horizontal sliding blocks 243 and the inner jacking blocks slide outwards (the fifth reset spring is compressed) towards the direction far away from the pot cover positioning center seat 22, the inner jacking blocks are propped against the side wall of the pot cover on the inner side, the outer punching jacking blocks punch the side wall of the pot cover from the outside to the inside, the front ends of the outer punching jacking blocks 246 punch the side wall of the pot cover, and the outer punching jacking blocks 246 press the side wall of the position of the pot cover into the punching yielding holes 248 and fracture the side wall to form cutting holes. Therefore, a plurality of inner punching mechanisms can simultaneously punch a plurality of cutting holes 41 on the side wall of the pot cover. In addition, since the front end of the outer punching top block is in a right triangle shape, the outer punching top block only punches the side wall of the pot cover to form a cut hole 41, and the side wall of the part is sunk into the inner side of the pot cover, so that no waste is generated, and the cut hole 41 is downward.
In the punching process, the upper die and the lower die are folded, and the positioning groove 13 of the upper die holder presses the whole pot cover so as to prevent the pot cover from moving when being punched.
When the upper die 1 ascends, the third reset spring and the sixth reset spring respectively drive the punching driving sliding block 234 and the punching driving sliding block 244 to ascend, and similarly, the first reset spring, the second reset spring, the fourth reset spring and the fifth reset spring also drive the respective sliding rods and the horizontal sliding blocks to slide and reset so that the outer pressing block and the inner punching pressing block are separated from the side wall of the pot cover, and the outer punching pressing block and the inner pressing block are separated from the side wall of the pot cover, so that a worker or a robot can take out the pot cover with the punched holes.
After the pot cover of the invention is punched with holes, the side wall of the pot cover is provided with a plurality of holes 42 and cutting holes 41 in a staggered and interval way.
