The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Referring to figs. 1 through shown in Figure 3, a kind of Multi-stage ram mould structure, formed by upper baffle plate 1 and lower baffle plate 2, described upper baffle plate 1 is fixedly connected with multistage drift 3, described lower baffle plate 2 is connected with counterdie fixed head 5 by connecting bolt 4, be provided with two bottom plates 6 between described lower baffle plate 2 and counterdie fixed head 5, described counterdie fixed head 5 inside be disposed with interior movable punching cover 7, in movable punching cover 8 and outer movable punching cover 9, are provided with punching cover driving shafts 10 in the middle of described interior movable punching cover 7.
Further, described multistage drift 3 becomes stepped connecting to form successively by one-level drift 301, secondary drift 302 and three grades of drifts 303, described one-level drift 301 and secondary drift 302 are provided with bending distortion inclined-plane 304, are provided with several drift pins 305 on described three grades of drifts 303.
Further, described interior movable punching cover 7, in movable punching cover 8 and outer movable punching cover 9 belows be respectively arranged with that interior band lacks resilient sleeve 11, middle band lacks resilient sleeve 12 and lacks in addition resilient sleeve 13, also be provided with drift pin hole 14 on described outer movable punching cover 9.
Further, be provided with slide block 15 between described two bottom plates 6, described slide block 15 is connected with slide block back-moving spring 16, described back-moving spring 16 is fixedly connected with sliding block spring fixed head 17, described sliding block spring fixed head 17 also is fixedly connected with counterdie fixed head 5, and described slide block 15 also is connected with punching cover driving shaft 10.

The operation principle of the present embodiment is as follows:
When making workpiece, it uses step as follows:
When the multistage drift 3 of step 1) was stamped down to the plane that reaches counterdie fixed head 5, punching cover driving shaft 10 was not subject to the strength effect, keeps motionless, so it is motionless that slide block 15 also keeps, interior movable punching cover 7 tops are stressed, because slide block 15 supports, also keep motionless, as shown in Figure 4.
Step 2) multistage drift 3 continues downward punching presses, core contacts with punching cover driving shaft 10, and drive it and move downward, during 10 motion of punching cover driving shaft, by with the conjunction surface of slide block 15, with slide block 15 to the both sides extruding, when multistage drift 3 moves to bending distortion inclined-plane 304, movable punching cover 8 belows during slide block 15 moves to, as shown in Figure 5.
The multistage drift 3 of step 3) continues downward punching press, interior movable punching cover 7 is due to the support that lacks slide block 15, being out of shape 304 bottoms, inclined-plane by bending moves downward, during motion, bending distortion inclined-plane 304 will play the bending effect, when movable punching overlaps 8 in the secondary drift 302 of multistage drift 3 moves to, slide block 15 moves to the below of outer movable punching cover 9, as shown in Figure 6.
The multistage drift of step 4) 3 continues downward punching presses, and interior movable punching cover 7 continues to move downward, and during secondary drift 302 drives, movable punching cover 8 moves downward, and drift pin 19 arrives 14 tops, drift pin hole, as shown in Figure 7.
The multistage drift 3 of step 5) continues downward punching press, in movable punching cover 7 and in movable punching cover 8 move downward, drift pin 19 pours in drift pin hole 14, slide block 15 continues to move to both sides, when slide block 15 moved to counterdie fixed head 5 below fully, three grades of drifts 303 of multistage drift 3 flushed with counterdie fixed head 5, and multistage drift 3 continues downward punching press, complete whole step, as shown in Figure 8.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
