The equipment for removing a profiled mandrel with a helical profile from a crimped workpiece includes a body, a mounting unit, and a mechanism for removing the mandrel from the workpiece. The fixture assembly and the mechanism for removing the mandrel from the workpiece are mounted in the body. The mechanism for removing the mandrel from the workpiece is made in the form of a screw-nut pair. The nut is connected to the body by means of a locking element, and the screw is made on one side with a flange part for connection to the mandrel in the fastening assembly, and on the other side is provided with a means for its rotation. In addition, the fastening assembly includes breadcrumbs for fixing the screw of the extraction mechanism with the mandrel and a support element for the flange part of the workpiece.
The utility model belongs to the mechanical engineering industry, in particular it concerns equipment for metal forming, and can be used to remove a mandrel from a crimped workpiece.
