Background technique

At present, in the process of insulating glass processing, the spacers used are mainly divided into two types, one is the flexible warm edge spacer, and the other is the non-flexible spacer, and the non-flexible spacer needs to be bent or spliced into the insulating glass. According to the shape, the non-flexible spacer is divided into metal spacer, non-metal spacer, metal and non-metal composite spacer according to the material. For the non-flexible spacer, the domestic industry standard thickness is 6.5mm, and the common width is 5.5mm. ——26.5mm, the width span is wide, and there is a deviation between the British/American size and the domestic spacer width standard in foreign countries. For spacers with different widths, cutter heads with corresponding widths are required to fold out spacer frames with qualified corners. Otherwise, it will cause problems such as out-of-tolerance, deformation, and damage of the bending corner. Although the current spacer bending machine cutter heads in the market have different shapes and sizes, and the structure is divided into integrated and split handles, they are suitable for different widths. The spacer bars are the corresponding configuration of "one piece, one knife". For this reason, a bending machine needs to be equipped with a large number of cutter heads of different widths to meet the needs of users for processing spacer bars of different widths. The equipment user is a production cost input, and the tool change operation also brings extra work and time-consuming to the operator, reducing the output efficiency. In view of the above problems, it is necessary to improve the relevant mechanisms of the bending machine.
