The return middle part 22 is arranged between the forming part 21 and the return end part 23 and is used to transition the connection between the forming part 21 and the return end part 23. The forming part 21 is used to drive the slider 1 to the position where the stamping die is performing stamping on the stamping material strip 6. The return end part 23 is used to drive the slider 1 to return to its position. The return middle part 22 is used to transition the slider 1 from the stamping position to the return position. The forming part 21, the return middle part 22, and the return end part 23 are integrally formed. A feeding pad 3 is provided at the bottom of the slider 1. The feeding pad 3 is mounted on the lower die 5. Balls 31 and / or rollers 32 are rollingly connected to the feeding pad 3. The slider 1 rolls with the feeding pad 3 through the balls 31 and / or rollers 32, thereby converting the sliding friction between the slider 1 and the lower die 5 into rolling friction, thereby providing a basis for achieving high-speed feeding.

[0036] refer to Figure 6 A fixed plate 54 is arranged on the upper side of the slider 1, and the stamping strip 6 is arranged between the slider 1 and the fixed plate 54. The fixed plate 54 is installed on the lower die 5. The stamping strip 6 is between the upper side of the slider 1 and the lower side of the fixed plate 54. The fixed plate 54 is used to stabilize the position of the stamping strip 6, so that the slider 1 can drive the position of the stamping strip 6 more stably, thereby making the feeding more stable.

[0037] refer to Figure 2 and Figure 6 The lower die 5 includes a lower base plate 51, a lower pad 52, and a lower mold plate 53. The lower pad 52 is mounted on the lower base plate 51, and the lower mold plate 53 is mounted on the lower pad 52. The feed pad 3 can be mounted on the lower base plate 51. Slide grooves that match the movement range of the slider 1 can be provided on the lower pad 52 and the lower mold plate 53, so that the slider 1 can move back and forth on the lower die 5. The fixing plate 54 can be mounted on the lower mold plate 53.

[0038] refer to Figure 2 and Figure 6 The fixed plate 54, the slider 1, and the feeding pad 3 are all provided with channels through which the driving rod 2 can pass. Similarly, the lower seat plate 51 and the lower template 53 are also provided with channels through which the driving rod 2 can pass, thereby avoiding interference with the driving rod 2.

[0039] refer to Figure 2 、 Figure 6-Figure 8 In order to further increase the feeding speed, a first spherical bearing 11 and a second spherical bearing 12 are installed in the slider 1 through an axis to match the driving rod 2. The first spherical bearing 11 and the second spherical bearing 12 are respectively distributed on both sides of the driving rod 2 and roll friction with the side of the driving rod 2, so that the friction generated between the driving rod 2 and the slider 1 during driving is rolling friction, which further provides a basis for high-speed feeding.

[0040] refer to Figure 2-Figure 5 In order to realize the synchronous feeding of the stamping material strip 6 when the slider 1 is displaced, a material digging assembly is provided in the slider 1, and the material digging assembly includes a material digging block 41 and a material digging spring 42. A first spring groove 13 is provided in the slider 1, and one end of the material digging spring 42 is against the bottom end of the first spring groove 13, and the material digging block 41 is abutted on the other end of the material digging spring 42. A material digging slope 411 is provided on the material digging block 41, and the material digging slope 411 cooperates with the positioning hole of the stamping material strip 6. The material digging block 41 feeds the stamping material strip 6 through the material digging slope 411, so that when the slider 1 moves to the stamping forming position (that is, when it moves to the left), the digging of the material digging block 41 The top of the material slope 411 is in the positioning hole of the stamping material strip 6 and the straight surface of the high side of the material tapping slope 411 extending into the positioning hole of the stamping material strip 6 is used to push the stamping material strip 6 to move to the left and reach the stamping and forming position, thereby feeding the material. Then the slider 1 starts to move from the stamping and forming position toward the return position (that is, when moving to the right). At this time, the material tapping block 41 uses the material tapping slope 411 and with the cooperation of the material tapping spring 42 to achieve retraction (that is, the material tapping block 41 moves downward). When the slider 1 reaches the return position, the material tapping slope 411 of the material tapping block 41 slides into the positioning hole of the stamping material strip 6 again, thereby continuously cycling back and forth.

[0041] refer to Figure 2 and Figure 3 In order to adapt to the high-speed feeding environment, a shock-absorbing pad 43 is installed at the bottom of the spring groove, and one end of the material-moving spring 42 close to the bottom of the first spring groove 13 rests on the shock-absorbing pad 43.

[0042] refer to Figure 1 and Figure 2In order to further cooperate with the high-speed feeding environment and avoid the situation where the slider 1 is not in place and gets stuck due to the rapid reciprocating motion, a second spring groove 14 is opened at one end of the slider 1, and a booster spring 15 is installed in the second spring groove 14. One end of the booster spring 15 is against one end of the slider 1, and the other end of the booster spring 15 is against the side of the slide groove on the lower template 53 of the lower mold 5, thereby providing a pre-thrust for the slider 1 through the booster spring 15 to ensure that the slider 1 will not interfere with the drive rod 2 during a long period of high-speed movement.
