Description

Technical Field

[0001] The invention relates to the technical field of grabbing mechanisms, and in particular to a full-automatic grabbing mechanism used on a wire drawing die. Background Art

[0002] A wire drawing die is a tool used in the metal pressure processing process. It uses external force to force the metal through the die, so that the cross-sectional area of ​​the metal is compressed and finally obtains the desired cross-sectional area shape and size. Wire drawing dies are usually made of high-hardness materials such as hard metal or diamond to withstand the high pressure and wear generated by the metal wire during the wire drawing process. There is a circular hole in the center of the wire drawing die, and the size of the hole determines the diameter of the metal wire passing through the die.

[0003] Since the wire drawing die has a hole in the center, the existing gripping mechanism may not be accurately positioned during the gripping process, affecting the subsequent use accuracy and service life of the wire drawing die. During the gripping process, if the gripping force is too large or the gripping method is improper, the die may be damaged, especially the center hole area used for wire drawing processing.

[0004] Existing gripping mechanisms mostly use clamps to grab the outside of the mold, which cannot ensure that the installation process can be accurately aligned after grabbing, resulting in the wire drawing dies colliding with each other during installation, reducing the wire drawing accuracy and the service life of the mold.
