A plurality of pneumatic cylinders 14 are disposed on the clamping body 11 below the pressing portion 132 , and each has a cylinder shaft 141 . A main slide plate 15 is to utilize two swing arms 151 to pivot with the clamping platform body 11, and it can be driven by a power source (not shown in the figure), so that the main slide plate 15 does a left and right swing movement relative to the clamping platform body 11 (with reference to FIG. 2 direction as the benchmark). Several female folder groups 16 are fixedly arranged on the main slide plate 15, and it has a cylindrical body 161, is provided with a hollow room 162 in the center of the cylindrical body 161, and a female folder guide rod 163 is exactly located in this hollow room 162, the A row of gear segments 164 is provided at the bottom end of the female clip guide rod 163 , and the female clip 165 is pivotally mounted on the axis of a gear 166 meshing with the gear row segments 164 . A secondary slide plate 17 is located between the clamping platform body 11 and the main slide plate 15, and the secondary slide plate is also pivotally connected with the swing arm 151. In addition, several pivotable bearing seats 171 are provided on the secondary slide plate 17, each bearing The seat 171 has a groove 172 . A plurality of opening rockers 18 are pivotally arranged in the groove 172, and the controlled part 181 at one end close to the clamp body 11 is sandwiched between the pressing part 132 and the cylinder shaft 141, while the other end is a U-shaped frame holding part 182, the female clip guide rod 163 is located in the U-shaped frame holding part 182, and is limited by the second retaining ring 183, so that the female clip guide rod 163 of the female clip group 16 is limited in the position except by the left and right swing of the main slide plate 15 In the frame holding part 182, it can move up and down by the seesaw movement of the opening rocker 18, so that the female clip 165 can be opened and closed.

When the cutting device cuts the continuous wire into blanks of appropriate length, the opening cam 12 just rotates to the low point. At this time, the cylinder shaft 141 of the pneumatic cylinder 14 also drives the controlled part 181 and the roller of the opening rocker 18 at the same time. The pressing part 132 of the seat 13 moves upwards, because the opening rocker 18 is pivotally arranged in the groove 172 of the auxiliary slide plate 17, so when the controlled part 181 moves upwards, the frame holding part 182 drives the female clip guide rod 163 downwards , so that the female clamp 165 clamps the blank. At this time, the power source drives the main slide 15, the auxiliary slide 17 and the clamping platform body 11 to perform a swing movement, and the blank is clamped from the cutting device to the first stamping die set. When the first stamping die set starts stamping, the opening cam 12 turns to the high point, which will forcefully drive the pressing part 132 and the controlled part 181 to move downward, and then the frame holding part 182 will drive the female clip guide rod 163 upward, Let the female clip 165 release the blank, and then use the power source to drive the main slide 15 and the auxiliary slide 17, and bring the female clip 16 back to the cutting device to perform the second clamping action. Of course, the semi-finished product is punched from the first stamping. The clamping actions from the die set to the second stamping die set and from the second stamping die set to the third stamping die set are performed simultaneously.

It can be seen from the clamp table structure of the conventional forging parts forming machine above that the main slide 15, the auxiliary slide 17 and the clamp body 11 are pivotally connected by the swing arm 151, because the combined weight of the main slide 15 and the auxiliary slide 17 is relatively large. It is heavy, so when doing left and right swing movements, its inertial effect is large, which will cause a large loss to the copper lining of the swing arm 151 pivot and other parts. The action of clamping is not smooth, thus affecting the overall forging rate.
