[0002] A wire press is a necessary tool for conducting wire connection pressing in the basic construction and maintenance of power lines in the power industry. Wire presses are divided into hydraulic wire presses, large-tonnage wire presses (presses), insulating terminal wire presses, split-type wire presses of crimping pliers, and hand-operated hydraulic wire presses. During operation, the workpiece to be pressed is placed in the pressing die within the crimping pliers, and the moving mechanism moves the crimping pliers to the appropriate position to be pressed.
