Machining method of horn-shaped seal head

Abstract

The invention provides a machining method of a horn-shaped seal head. The machining method comprises machining steps including material selection, scribing, blanking, stamping, part taking, groove machining and grinding and acid pickling. The overall cold stamping is realized through preset clearance cooperation of an existing stamping machine and a stamping die, the machined seal head has good size and shape consistency, the accuracy requirement of a foreign power spinning machine is met, a curved surface machined through the stamping die is smooth, the curved surface of the seal head and the round section of a lower straight barrel are in smooth transition, the condition of scrapping caused by edges and marks and even cracking of the seal head in the machining process of the strong spinning machine is avoided, and the scrappage is very low; meanwhile, an ordinary operator of the stamping machine can master the machining method after a little training, the technical requirements for the operator are lower, the production efficiency is remarkably improved, and the delivery term is greatly shortened.

Description

technical field [0001] The invention relates to a manufacturing process of a head, in particular to a processing method of a trumpet-shaped head. Background technique [0002] The head is mainly used as a support for stirring equipment or sewage treatment equipment. It is usually in the shape of a trumpet. The large open end at the bottom is welded to the base, and the small open end at the top is welded to the above stirring equipment or sewage treatment equipment. At present, the main method of domestic production of the head is to rely on the spinning of foreign strong spinning machines. The heads produced by strong spinning machines have higher precision, but the investment in equipment is relatively large, especially when it is necessary to process different specifications and sizes. When sealing the head, it is necessary to replace different fixtures and numerical control programming, so the operator’s operating skills are required to be high; in addition, during the w...

Problems solved by technology

At present, the main method of domestic production of the head is to rely on the spinning of foreign strong spinning machines. The heads produced by strong spinning machines have higher precision, but the investment in equipment is relatively large, especially when it is necessary to process different specifications and sizes. When sealing the head, it is necessary to replace different fixtures and numerical control programming, so the operator’s operating skills are required to be high; in addition, during the working process of the strong rotary machine, due to contact with the extrusion wheel, there are wheel marks on the finished head, Excessive contact pressure will also cause the head to crack, so the scrap rate is high during batch processing, and equipment maintenance is difficult. At the same time, production efficiency is greatly reduced and the delivery period is extended.
