Problems solved by technology
Since the edge of the metal bottom blank is only bent once in the prior art, burrs will be generated at the edge of the processed bottom blank, which often cuts the user's fingers and causes certain personal injury to the user; and , the exposed burrs affect the appearance of the vessel and reduce the grade of the vessel; in addition, in the prior art, the edge of the metal bottom blank is usually bent by manual operation of the bending tool, and the bending tool is heavy and difficult to operate , so the labor intensity of the operator is increased, and the processing efficiency is low. The shape of the bent edge of the processed product is completely determined by the proficiency of the operator, so the consistency of the processed product is poor and the quality is unstable.

The invention discloses a method for hemming a metal base blank of an enamel dish. The method comprises the steps that a first hemming position and a second hemming position on the edge of the metal base blank are determined; the metal base blank is made to be in the rotating state; a first hemming device hems the edge of the rotating metal base blank at the first hemming position, and a first bent edge is formed on the edge on the metal base blank; a second hemming device hems the edge of the rotating metal base blank with the first bent edge for the second time at the second hemming position, and a second bent edge connected with the first bent edge is formed on the edge of the metal base blank. The method is easy to implement, practicable and high in operability and improves hemming efficiency, no burrs exist on the exposed edge of the machined metal base blank, no personal injuries are caused to users, the enamel dish is safer to use and is attractive in appearance, the level of the machined enamel dish is improved, and the quality reliability of the machined enamel dish is good.
Description
technical field [0001] The invention relates to the technical field of enamelware production methods, in particular to a method for curling the metal bottom blank of the enamelware. Background technique [0002] Enamel ware is widely used in daily life. It is formed by stamping and stretching a metal bottom blank to form a basin or bowl shape, and coating and firing enamel on both sides of the metal bottom blank. In the prior art, after the pot-shaped or bowl-shaped vessel is formed by punching and stretching the metal bottom blank, the edge of the metal bottom blank needs to be bent. Since the edge of the metal bottom blank is only bent once in the prior art, burrs will be generated at the edge of the processed bottom blank, which often cuts the user's fingers and causes certain personal injury to the user; and , the exposed burrs affect the appearance of the vessel and reduce the grade of the vessel; in addition, in the prior art, the edge of the metal bottom blank is usu...
