Method for manufacturing can body of deep-drawn square two-piece can

The embodiment of the invention discloses a method for manufacturing a can body of a deep-drawn square two-piece can. The method comprises the steps that S1, a raw material plate is punched into an oval sheet material; S2, the sheet material is subjected to blank punching to form an oval blank can; S3, the blank can is stretched to form a square can with four filleted corners; the outer side of afemale die of a die which is stretched into the square can extends downwards to form a guide structure with an edge pressing die; the height of the square can is greater than that of the blank can; and S4, the square can is subjected to diameter-expanding and trimming to form the can body . The guide structure composed of the female die and the edge pressing die is adopted when the square can is formed through stretching, material flowing at the time of forming filleted corner parts can be guided, protrusions are restrained, and cracking of the filleted corner part can further be avoided. 本申请实施例公开了一种深冲方形二片罐的罐体制造方法，包括：
