then the punch mechanism 4 stops punching and rises, at this time, the punching column 403 automatically moves downwards due to inertia and the accumulated force of the connecting spring 402, at this time, the formed product in the feed opening a12 is pushed downwards, and then the force of pushing the punching column 403 downwards is conveniently applied to the formed product, so that the outer side surface of the formed product can be well ground by the grinding ring 11 which is matched with the rotation, the grinding quality and efficiency are improved, meanwhile, the formed product in the feed opening a12 is pushed downwards, the formed product can well fall into the feed opening b19 from the feed opening a12 and then is discharged, the blockage in the later period is avoided, then, one-time punching is completed, and then, the operation is continued as shown above, and therefore, a series of operations are completed.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
