Forming die for alloy reducing pipe and method for processing reducing pipe using same

Abstract

The invention provides a forming die for an alloy reducer pipe and a method for processing a reducer pipe through same. The die comprises a main die, wherein a secondary die is fixed in the main die in an embedding manner; a formation chamber is arranged in the secondary die, and the inlet end of the formation chamber is used for bearing a blank in a blank channel; a pushing rod die block is mounted in the blank channel; and a pushing rod is mounted on the pushing rod die block and is capable of driving the pushing rod die block to push the blank to slide from the blank channel into the formation channel so as to realize the formation of the reducer pipe. According to the forming die for the alloy reducer pipe, the die separating design is adopted; a traditional vertical formation way of the reducer pipe is replaced by a horizontal formation way through the die; the formation die is fixed to a device to avoid manual repeated dismounting, mounting and riveting of the die in formation process; the surface quality of the blank of the reducer pipe is greatly improved; the formation time of the reducer pipe is greatly reduced; 30 parts can be formed by 10min, and the formation time is reduced by 50min; the formation efficiency is increased by 83%, and thus the production efficiency is greatly improved; and the labor cost is saved.

Description

technical field [0001] The invention relates to the field of metal material processing technology, in particular to a forming die for an alloy variable diameter pipe and a method for processing the variable diameter pipe by using the same. Background technique [0002] Metal reducing pipe fittings are widely used in domestic and foreign shipbuilding and marine engineering industries. At present, the forming of reducing pipes mostly adopts three methods: pipe press forming, bar direct machining forming, and plate tailor welding forming. Among them, tailor welding reducing pipes have weld seams, the production cycle is long, and product quality is difficult to guarantee; bar machine The processing and forming of reducing pipes has low material utilization rate and is only suitable for the forming of small-sized reducing pipes; the pipe compression molding method uses pipes as raw materials, and the compressed reducing pipes can meet the standard requirements, and the material ...
