Forming die of copper buckle for locking copper strip

Abstract

The invention introduces a forming die of a copper buckle for locking a copper strip. The forming mould comprises an upper die holder installed on a press, and a lower die holder fixed to a machine tool; the upper die holder is provided with an upper concave die connected to and located on the upper die holder through a fixed plate, and a pressing plate is installed between the fixed plate and theupper die holder; the lower die holder is provided with a lower concave die fixed to the lower die holder through a lower template; the upper end face of the upper concave die is further fixedly provided with an upper template, and hollow sleeves are installed between the upper template and the fixed plate; the pressing plate and the upper die holder are provided with relief holes, and the hollowsleeves are fixed to the upper template by bolts; and moderate load reset springs are installed between the upper die holder and the upper template, and the upper ends of the hollow sleeves can slidably penetrate the relief holes after compression of the moderate load reset springs. According to the forming die provided by the invention, the qualification rate of products is improved, and the reliability is higher.

Description

technical field [0001] The invention relates to the production and manufacture of precision copper tubes, in particular to a copper buckle forming mold for locking copper strips, and belongs to the technical field of precision copper tube manufacturing auxiliary tools. Background technique [0002] Due to the large problems of air quality in many places, air-conditioning equipment is becoming more and more important to people's lives, and as the technology of air-conditioning equipment becomes more and more mature, in the process of producing air-conditioning The requirements for copper pipe materials are also getting higher and higher. Because the copper tubes used in air-conditioning equipment are different from ordinary copper tubes, it not only requires good thermal conductivity, but also requires good ductility and toughness, and it also needs to process threads on the inner wall, and even the wall thickness of the copper tubes There are very strict standards, so the r...
