Abstract

The invention provides a spinning forming device structure for metal thin-walled cylindrical workpieces, which can solve the problems of inability to guarantee working precision and low processing efficiency in traditional one-by-one spinning methods, and at the same time, unload the workpieces after the spinning processing is completed. It includes a mandrel and a spinning die. The spinning die includes a forming die and a bead roller. The mandrel runs through the shaft hole of the forming die. The forming die is fastened to the mandrel by a positioning fastening device, and the mandrel is connected to the main shaft of the machine tool through transmission. , during spinning, the forming mold rotates with the mandrel under the drive of the main shaft of the machine tool, and the outer periphery of the forming mold is provided with a forming surface. The outer peripheral surface of the machine is a beading profile matching the entire forming surface, and the beading roller is parallel to and facing the axis of the forming die.

Description

technical field [0001] The invention relates to the field of spinning die structure, in particular to the field of spinning forming of metal thin-walled cylindrical work, in particular to a spinning forming die structure of metal thin-walled cylindrical workpiece. Background technique [0002] Spinning is to fix the flat or hollow blank on the mold of the spinning machine. While the blank is rotating with the main shaft of the bed, the blank is pressed with a spinning wheel or a driving rod to cause local plastic deformation. Under the joint action of the feed motion of the rotary wheel and the rotational motion of the blank, the local plastic deformation is gradually extended to the entire surface of the blank, and it is closely attached to the mold. The spinning process carried out under normal temperature conditions is called cold spinning. . Spinning products have a variety of shapes. Through spinning, various tasks such as forming, reducing diameter, closing, back seal...
