Welding ring product flatness control process

Abstract

The invention discloses a welding ring product flatness control process which involves a voltage controller and a heating coil. The process is characterized in that a wire is heated to be surrounded into a circle, and the surrounded circle is cut off to fall down into a constant temperature mold barrel, is punched by a punch pin in the constant temperature mold barrel and flattened, and falls intoa container from the constant temperature mold barrel. By means of the process, the disqualification ratio of welding rings is effectively reduced, and the yield is improved and can be improved by 2%about.

Description

technical field [0001] The invention belongs to the technical field of brazing, in particular to a process for controlling the flatness of welding ring products. Background technique [0002] The flatness of the welding ring produced by the existing process has a failure rate of about 5%. It is difficult to rely on sorting in the later stage, and it is not easy to pass the inspection manually. The welding ring with unqualified degree is removed, and the production efficiency is low; the welding ring is not flat: the unqualified ratio is high, resulting in high production costs and a waste of manpower; when the welding ring is flattened, it will lead to unqualified use by customers and cause serious welding problems in the later stage. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a production process capable of improving the flatness rate of welding rings. [0004] In order to achieve ...
