step three: placing a workpiece on a lower die, starting a punch body 100, wherein a power device in the punch body 100 can drive an upper punch block 110 and an upper die to move downwards, a connecting rod 230 can drive the lower die to move towards the interior of the punch body 100, and a baffle 300 moves upwards while moving towards the interior of the punch body 100, so that the baffle 300 can block the upper die and the lower die, and after the upper die impacts downwards, the power device can drive the upper punch block 110 to move upwards to drive a driving rod 220, the connecting rod 230 and the baffle 300 to move to the original positions, so that one-time stamping is completed;
step four: after the punch body 100 is used for a period of time, the third screw 243 can be unscrewed, at this time, the fixing shell 241 can be removed from the fixing plate 210, then the screw rod 242 can be rotated, the adjusting block 249 moves out of the fixing shell 241, then the new sliding block second 247, the spring 248 and the adjusting block 249 can be replaced, the new spring 248 can be moved into the fixing shell 241 by rotating the screw rod 242, then the fixing shell 241 can be placed at the original position, the third screw 243 is screwed between the two clamping plates 245, and the position of the fixing shell 241 is fixed, so that the replacement of the spring 248 is completed.
The working principle is as follows: when the die is used, the first screw 222 and the second screw 234 are screwed out, so that the driving rod 220 can be separated from the upper punch 110, and the driving rod 220 can be separated from the connecting rod 230, so that the driving rod 220 can not block the side part of the upper punch 110, then the upper die can be fixed on the bottom surface of the upper punch 110, the fourth screw 252 and the fifth screw 262 are screwed out, then the round block 261 and the baffle plate 300 can be separated, and the inserting rod 253 can be pulled out of the fixing block 251, so that the arc-shaped rail 260 can not block the side part of the sliding seat 400, then the lower die can be fixed on the top surface of the sliding seat 400 from one side of the sliding seat 400, after the upper die and the lower die are fixed, the first screw 222 is screwed onto the upper punch 110, so that the top end of the driving rod 220 is connected with the upper punch 110, the second screw 234 is screwed onto the driving rod 220, the bottom end of the driving rod 220 is connected with the connecting rod 230, then the inserting rod 253 is reinserted into the fixing block 251, screwing the screw IV 252 to the original position, fixing the position of the inserting rod 253, screwing the screw V262 into the baffle plate 300, and connecting the round block 261 with the baffle plate 300;
placing a workpiece on a lower die, starting a punch body 100, wherein a power device in the punch body 100 can drive an upper punch block 110 and the upper die to move downwards, the upper punch block 110 can drive the top end of a driving rod 220 to move downwards through a first rotating shaft 221, the driving rod 220 can drive a connecting rod 230 to move towards the interior of the punch body 100 through a second rotating shaft 233, the connecting rod 230 can drive a baffle 300 to move towards the interior of the punch body 100 through an L-shaped rod, meanwhile, the connecting rod 230 can drive a sliding seat 400 and the lower die to move towards the interior of the punch body 100 through a fixing rod 420, when the baffle 300 moves, a round block 261 can move upwards along an arc-shaped rail 260, so that the baffle 300 moves upwards while moving towards the interior of the punch body 100, so that the baffle 300 can block the upper die and the lower die, after the upper die impacts downwards, the power device can move the upper punch block 110 upwards, so that the driving rod 220 and the connecting rod 230 can move to the original positions, and the baffle 300 is far away from the punch body 100 and moves downwards to the original position along the arc-shaped rail 260, thus completing one-time punching;
when the punch press body 100 is moved downwards, the connecting rod 230 can drive the first sliding block 246 and the second sliding block 247 to slide towards the adjusting block 249, and at this time, the second sliding block 247 can extrude the spring 248, so that the spring 248 can buffer the connecting rod 230 to buffer the punch press body 110, the screw rod 242 can be rotated according to needs, the distance between the adjusting block 249 and the second sliding block 247 can be adjusted, so as to adjust the buffer strength of the spring 248 on the connecting rod 230, after the punch press body 100 is used for a period of time, the third screw 243 can be screwed out, at this time, the connecting block 244 can be moved out between the two clamping plates 245, so that the fixing shell 241 can be taken down from the fixing plate 210, then the screw rod 242 can be rotated, so that the adjusting block 249 can be moved out of the fixing shell 241 from the opening of the fixing shell 241, and then the second sliding block 247, the spring 248 and the adjusting block 249 can be replaced, the new adjusting block 249 is connected to the fixing case 241 by rotating the screw 242, the new sliding block two 247 and the spring 248 are moved into the fixing case 241, then the fixing case 241 is placed between the two locking plates 245 and the fixing plate 210 again, the connecting block 244 is locked between the two locking plates 245 again, the sliding block one 246 is inserted into the fixing case 241, the screw three 243 is screwed between the two locking plates 245, the screw three 243 locks the position of the connecting block 244, and the position of the fixing case 241 is fixed, and the replacement of the spring 248 is completed.
