After the die is qualified in trial cutting, an 89.5mm wide strip coil is installed on an automatic feeding machine, the automatic feeding machine is synchronously connected with a press machine to achieve that the feeding machine sends 79.5mm to reach the position 1 once, an upper sliding block of the press machine drives an upper die base 1 to synchronously move downwards, the upper die base drives a first punch 5 and a second punch 6 to downwards enter a first lower punching die 16 to achieve first-step punching, and the press machine achieves one-time reciprocating motion. The feeder continues to feed materials of 79.5mm to reach the position 2, the press machine drives the upper die holder 1 to synchronously move downwards, first-step punching of newly-fed materials of 79.5mm is repeatedly achieved, meanwhile, the first upper punching die 7 and the second upper punching die 8 move downwards to enter the second lower punching die 17 to achieve second-step shape punching of the initially-fed materials of 79.5mm, and the press machine achieves one-time reciprocating motion.
The feeder continues to feed 79.5mm to reach the position 3, the press machine drives the upper die to synchronously move downwards, and the first step of punching on the newly fed 79.5mm material is repeatedly realized. And the shape is punched in the second step, the third upper punch die 9 enters the third lower punch die 18 to realize the third step of punching and bending of the 79.5mm material which is initially fed, and the press machine realizes one reciprocating motion. The feeder continuously feeds 79.5mm to reach the position 4, the press machine drives the upper die to synchronously move downwards, the first step of punching, the second step of shape punching and the third step of bending are repeatedly carried out on the newly fed 79.5mm materials, meanwhile, the fourth upper die 10 enters the fourth lower die 19 to cut and separate the 79.5mm materials fed initially, and the press machine realizes one-time reciprocating motion to obtain a finished product (as shown in figures 4-6).
The press machine and the feeder select an automatic mode, the die is opened and closed circularly, and continuous stepping punching is realized, so that a finished product is discharged in one stroke, the time and the labor are saved, the cost is saved, and the production efficiency is improved.
In one embodiment, the stripping spring 25 is installed between the upper supporting plate and the stripping plate, the stripping spring 25 is compressed when the die is closed to realize punching, the upper supporting plate is driven by the upper slide block of the press to ascend after punching, the upper die and the lower die are separated, and meanwhile, the stripping spring 25 realizes stripping of the stripping plate through self resilience force. And the floating pin spring 24 is pressed against the floating pin to support the belt material to be always in a horizontal plane when the die is separated, and is compressed when the die is closed, so that the floating pin moves downwards and is not crushed. And a material guide pin spring 26, wherein the material guide pin spring 26 is pressed against the material guide pin to control the forward conveying direction of the strip material and the action on the horizontal plane when the die is separated, and the material guide pin spring 26 is compressed when the die is closed, so that the material guide pin moves downwards without being crushed. The secondary positioning punch can be ensured to ensure the quality.
The above description is only for the purpose of creating a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
