The strength of the straight cylinder can body is enhanced.

Collapsible forming is a process of forming a specific structure of a mold. The main part of the die forming is formed by splicing 12 independent angle surface sliding blocks, the top cone of the die part moves up and down, the inclined surface of the top cone and the inclined surface of the sliding block push the sliding block to expand radially on a fixed track, and the polygonal solid geometric structure shape with 24 angle surfaces is formed for the can body of the cylindrical shell. The mechanism of the die is mechanically driven, so that the mechanism of the die can move according to the design requirement to complete the expansion and contraction action, and a certain force is applied to the tinplate metal by the expansion and contraction force, the tinplate metal can stably change the shape and the size of the tinplate metal within the parameter range, and the connection among the mass points is not damaged.

After the slide block expands along the track in the radial direction, a gap distance is formed between the slide block and an adjacent slide block, so that the metal of the cylindrical can is extended to form another 12 angular surfaces with the side length of 5.8mm and the diagonal side size of 65.8mm +/-0.2. The inclined surface of the tip cone pushes the slide block to expand radially, and the corners of the side edges of the slide block enable 24R 1 convex ribs to be formed in the transition between the polygonal corner surfaces. After the expansion forming is in place, the tip cone retreats, the annular spring on the sliding block contracts, so that the sliding block retreats to the middle of the mold along the fixed track, and the formed cylinder barrel-shaped container body with the polygonal shell-shaped geometric structure is removed from the mold. The working steps of forming the polygonal geometry of the can body are completed. ) And fifthly, the can body and the bottom cover are sealed and seamed together through a double seaming machine, and at the moment, the three-piece can with the polygonal can body with the geometric structure and the shape required by the design is formed.
