This application discloses a method for forming a round tube of a sheet material. The sheet material whose curling length is slightly larger than the circumference of the circular sheet material tube is placed on the central axis, and the first stamping is performed to make the sheet material bend and half-wrapped on the central axis. The two ends of the bent sheet are the first straight surface and the second straight surface; the first straight surface is reversed to the first stamping for the second time, so that the first straight surface is bent and wrapped in the The surface of the central axis; carry out the third stamping opposite to the first stamping on the second straight plate surface, so that the second straight plate surface is bent and wrapped on the central axis surface, and the edge part of the second straight plate surface and the first straight plate surface lap. This forming method directly bends a whole piece of sheet material into a circular tube, and the two ends of the sheet material are automatically lapped together during the stamping process, which facilitates the subsequent stamping and riveting. Compared with the prior art, the sheet material The forming operation of the round tube is more convenient, the process is simple, and labor and time are saved. The invention also discloses a plate circular tube forming die based on the plate circular tube forming method.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for forming a round tube of a plate. It also relates to a plate circular tube forming die based on the forming method. Background technique [0002] When processing tubular structural parts such as sheet metal round tubes, the existing processing method is: firstly, the sheet material is formed into two semicircles, and then the butt edges of the two semicircles are riveted respectively, and finally formed into a round tube . The method is complicated in operation, time-consuming and labor-intensive. [0003] Therefore, how to simplify the forming operation of the plate circular tube has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide a method for forming a circular plate tube to simplify the forming operation of the circular plate t...
