Description

Technical Field

[0001] The utility model relates to the field of cold heading dies, in particular to a cold heading die for an end cover. Background Art

[0002] The cold heading process is a process that utilizes the plastic deformation of metal under the action of external force. It usually requires the use of a mold to redistribute or transfer the metal volume to form the required parts or blanks.

[0003] When the existing cold heading die is cold heading, before the punch contacts the workpiece, the cover plate moves downward with the upper die to cover the upper opening of the cold heading forming cavity. At this time, the bar is closed by the sleeve hole and the cold heading forming cavity. Then, as the upper die continues to move downward, the punch pushes the workpiece downward in the sleeve hole until the workpiece is squeezed to the upper opening position of the cold heading forming cavity, and the cold heading forming process of the workpiece is completed.

[0004] However, after the end cover is cold headed, the upper edge of the metal end cover will be deformed and uneven due to the extrusion of the cold heading head, so the end cover after cold heading needs to be moved to a separate grinding and correction equipment for re-clamping and positioning before grinding and correction can be performed, which increases the operating procedures and reduces the overall efficiency of the processing.
