Problems solved by technology

[0002] Flanges are important connecting parts, and they are used in a huge number of practical projects. The existing manufacturing process of flanges is directly cutting and drilling square billets or round billets, and the processing time is long. In addition, the existing manufacturing process The central through hole of the flange needs to be cut out by a lathe. The lathe tool wears a lot, and because the central through hole of the flange is large, there are more scraps cut out, resulting in a very low yield of square billets and round billets. It is not conducive to the full utilization of raw materials and the reduction of flange costs

Abstract

The invention discloses a flange manufacturing technology. The technology comprises the steps of raw material thick-wall steel pipe re-inspection, forming of pipe blanks through cutting, heating, forging through a punch press, heat treatment, cutting and drilling, and marking and packaging. Thick-wall steel pipes serve as raw materials, and flange finished products are obtained after cutting, heating and forging, heat treatment, cutting and drilling. Compared with a traditional flange manufacturing technology, the technology remarkably improves the yield of the raw materials, greatly reduces generation of waste, effectively reduces the turning workload, prolongs the service life of a lathe cutter, and helps flange production enterprises to improve economic benefits.

Description

technical field [0001] The invention relates to the field of flange manufacturing, in particular to a flange manufacturing process. Background technique [0002] Flanges are important connecting parts, and they are used in a huge number of practical projects. The existing manufacturing process of flanges is directly cutting and drilling square billets or round billets, and the processing time is long. In addition, the existing manufacturing process The central through hole of the flange needs to be cut out by a lathe. The lathe tool wears a lot, and because the central through hole of the flange is large, there are more scraps cut out, resulting in a very low yield of square billets and round billets. It is not conducive to the full utilization of raw materials and the reduction of flange costs. Contents of the invention [0003] In view of the problems existing in the background technology, the object of the present invention is to provide a flange manufacturing process,...
