AI Technical Summary
In existing progressive die structures, when there are too many punches, there is insufficient space, and the springs cannot effectively reset the punches, resulting in low stamping efficiency.
It adopts a structure with multiple split switching rods and a movable base. The punching and resetting of the punch are controlled by the movement of the movable plate, which saves the installation space of the upper die and ensures the resetting function of the spring.
This allows for the installation of more punches within a limited space, improving stamping efficiency and ensuring effective punch reset, while reducing weight and material requirements.

[0023] The utility model is further described below in combination with the drawings.
[0024] As Figures 1-7 shown, a blade concentrated stamping split switching device of the utility model, including upper die holder 1 and multiple punch 12, the top of upper die holder 1 is equipped with multiple cover plates 2, each cover plate 2 is embedded in the long groove of upper die holder 1 and is fixed to form long channel, each channel is equipped with a movable plate 3, the bottom of each movable plate 3 is equipped with multiple grooves 4, the lower of movable plate 3 is multiple split switching connecting rods 5, each split switching connecting rod 5 corresponds a groove 4. Figure 3 As
[0025] The bottom of all split switching connecting rods 5 is fixed with the base 11 in overall receiving cushion block 6, the base 11 slides in the channel of overall receiving cushion block 6 along the axis direction parallel to split switching connecting rod 5, the top of each punch 12 is fixed with base 11, the bottom of overall receiving cushion block 6 is fixed with stamping blade block 7, the lower of stamping blade block 7 is template 8, the template 8 is equipped with notch 9, and the notch 9 is matched with stamping blade block 7.
[0026] As Figure 8 shown, all punch 12 is evenly connected on base 11.
[0027] The height of base 11 is less than the height of the channel of overall receiving cushion block 6, and the height difference distance D of both.
[0028] In working state, the movable plate 3 is located at the first position, and the top of all split switching connecting rods 5 abuts with the bottom surface of movable plate 3 body, so that movable plate 3 pushes all split switching connecting rods 5 to move downward during stamping. In non-working state, the movable plate 3 moves from the first position to the second position, and the top of each split switching connecting rod 5 corresponds to a groove 4 one by one, so that movable plate 3 cannot push all split switching connecting rods 5 to move downward during stamping.
[0029] The upper die holder 1 is provided with a cavity in which the whole receiving cushion block 6 moves up and down.
[0030] The stamping blade block 7 and the whole receiving cushion block 6 are pressed and fixed at the bottom of the upper die holder 1 by the bolts 10 at the bottom, which pass through the through holes of the stamping blade block 7 and the whole receiving cushion block 6 in sequence.
[0031] The depth of the groove 4 is consistent with the height difference distance D.
