Among this technical scheme, when punching press the disc, utilize automatic feeding mechanism to place the disc on the lower mould, then hydraulic cylinder action drives drift downstream, drift and disc contact to press and move disc downstream, disc and supporting bench contact utilize the recess that the drift lower extreme set up to make the disc warp, until contact each other between drift, lower mould and the backup pad, accomplish the punching press, form the tooth embryo. In the pressing process, the first spring contracts, and after the punching is finished, the first spring resets to jack the tooth blank upwards, so that the blanking is facilitated. The punching machine only punches the circular truncated cone structure on the disc, does not punch the circular truncated cone structure, and needs to be transferred to another punching machine for subsequent operation. This device can automatic feeding, reduces the burden, raises the efficiency.

Further, automatic feeding mechanism includes the support, the support upper end fixed mounting has the level to set up to push away the material cylinder, support one side is provided with the feed cylinder, fixed mounting has the material loading cylinder in the feed cylinder, the piston rod of material loading cylinder upwards sets up and fixed mounting has the bearing plate, the one end that the feed cylinder is close to the lower mould extends to the direction of being close to the lower mould and is provided with the connecting plate.

Thus, the feeding cylinder drives the disc to move, so that the disc positioned at the top is positioned on the outer side of the cylinder, the pushing cylinder moves to push the disc to the connecting plate, the disc is pushed to the lower die to be continuously pushed, and then the feeding cylinder moves by the same stroke, so that the disc positioned at the top is positioned on the outer side of the cylinder. When first spring was in the extension state, connecting plate and lower mould upper surface were located the coplanar, made things convenient for the material loading, raise the efficiency.

Furthermore, the upper surface of the lower die is concave to form a blind hole, the blind hole is arranged on one side, away from the charging barrel, of the through hole, a second spring is arranged in the blind hole, a positioning pin is fixedly mounted at the upper end of the second spring, and the positioning pin is in up-and-down sliding fit in the blind hole.

Therefore, the positioning pin is arranged, when the pushing cylinder acts, the disc is pushed to the position of the positioning pin for positioning, and the stamping precision is improved. When punching press, the drift compresses the locating pin, and under the second spring action, the locating pin can get into in the blind hole, avoids producing the influence to the punching press.

Further, the blind hole is provided with 3 and follows perforation circumference distributes the setting.

Thus, the disc feeding can be better positioned.

Furthermore, the material pushing cylinder is a multi-stage cylinder.

Thus, the space can be more reasonably utilized.
