[0013] 2. The stamping structure of the tapered roller cold heading machine with an adjustable stamping die is such that when the stamping head does not need to stamp the material, the stamping head and the support block need to be staggered, and the second hydraulic rod drives the rack to move, and the rack will drive the gear to rotate, thereby realizing the effect of a cyclic swinging connecting plate, and the effect of the swinging stamping head can be achieved. When the stamping head moves toward the support block, the swinging plate retracts and moves to a position away from the support block. When the stamping head and the support block are staggered, the swinging plate moves driven by the third hydraulic rod, and the material can be cut off and the material placement effect is completed. The stamping head swings back to its original position to complete the effect of stamping the tapered roller, thereby achieving the effect of improving the stamping efficiency.

The material pipe is used to guide the material and is used in conjunction with manual operation by workers. When the material needs to be stamped and cut, the raw material is inserted into the ejector block, and the third hydraulic rod is turned on to drive the collar to move. The collar will drive the connecting column to move, and the connecting column will drive the swing plate to rotate along the support rod. The swing plates are staggered and used in conjunction with the cutting ring to achieve the effect of cutting the material. When the slide hole coincides with the material trough, the tension applied by the spring will drive the ejector rod to move, and the ejector rod will squeeze the material out of the inner wall of the slide hole, and then the material is placed in the material trough to achieve the effect of placing the material.
