Step two: after the upper clip a is fixed, the square stamping part 35 stamps the upper clip a into the stamping groove 36, and the upper clip a is gradually bent and deformed until the upper clip a is in a U shape, then the U-shaped upper clip a slides downwards along the side wall of the bending die 37, during the downward sliding process, the supporting die 38 moves downwards synchronously under the external force, after the supporting die 38 contacts the pressing column 411, the pressing column 411 and the inverted triangle plate 412 move downwards, then the two V-shaped rods 413 start to rotate around the hinge point, then the squeezing plates 415 on the two V-shaped rods 413 move inwards synchronously after being squeezed, and the squeezing plates 415 squeeze the left and right sides of the stamped upper clip a simultaneously.

Step three: after the square stamping part 35 finishes stamping the upper clamp piece a to be machined, and when the square stamping part 35 moves upwards, the lower pressing plates 402 commonly arranged on the plurality of square stamping parts 35 contact the blanking spring rods 404, then the square stamping part 35 continues to move upwards, at this time, the lower pressing plates 402 gradually receive the downward elastic force of the blanking spring rods 404, after the elastic force of the blanking spring rods 404 gradually increases, the lower pressing plates 402 start to move downwards, meanwhile, the lower pressing columns 401 sliding through the inside of the square stamping part 35 start to move downwards, the lower pressing columns 401 extend out from the lower end of the square stamping part 35, the extended lower pressing columns 401 extrude the upper clamp piece a clamped at the lower end of the square stamping part 35, and then the extruded upper clamp piece a and the square stamping part 35 are separated from each other.

Step four: after the upper clamp piece A on the square stamping part 35 is separated, the square stamping part 35 continues to move upwards, in the process that the square stamping part 35 moves upwards, the linkage plate 285 on the connecting frame 33 contacts the lower end of the clamping triangular block 283, the lower end of the clamping triangular block 283 is a horizontal plane, therefore, the clamping triangular block 283 cannot retract into the sliding groove 282 after being subjected to external force, at the moment, the linkage plate 285 drives the vertical plate 27 to synchronously move upwards through the clamping triangular block 283 until the moving height of the vertical plate 27 exceeds the height of the machined upper clamp piece A, the electric slide block 22 continues to drive the machined upper clamp piece A to move forwards and backwards through the clamp push rod 23 until the machined upper clamp piece A is away from a machining area and then is uniformly collected.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
