Abstract

The invention discloses a metal hose forming device and a forming method thereof. The metal hose forming device comprises a workbench, and a rolling mechanism, a steel pipe rounding mechanism, a lubricating mechanism, a first shallow wave forming mechanism, a second shallow wave forming mechanism, a third shallow wave forming mechanism, a dense wave forming mechanism and a high-pressure cleaning mechanism which are sequentially arranged on the workbench from left to right, continuous precision forming of the metal corrugated pipe is achieved, a multi-pass mutually-staggered spinning die is adopted for shallow wave forming of a pipe blank, the three-roller planet wheel rolling technology is adopted for dense wave forming, and the metal corrugated pipe forming device has the advantages of being high in production efficiency and good in forming quality. The axes of the three rolling dies are parallel to the axis of the corrugated pipe and are evenly distributed around the axis of the corrugated pipe by 120 degrees, and therefore the corrugated pipe can be gripped in conveniently.

Description

technical field [0001] The invention relates to the technical field of metal hose manufacturing, in particular to a metal hose forming device and a forming method thereof. Background technique [0002] Corrugated metal hose (English name Corrugated metal hose) is one of the metal hose series products. Corrugated metal hose (hose for short) is a high-quality flexible pipe in modern industrial pipelines. Fatigue and high pressure, good temperature resistance, corrosion resistance, strong sealing and many other characteristics, much longer life than other hoses (rubber hose, plastic hose). It is widely used in aviation, aerospace, petroleum, chemical, steel, electric power, papermaking, construction, rubber, textile printing and dyeing, medicine, food, transportation and other industries. With the development of modern industry, the demand for high-quality, high-performance corrugated metal hoses will increase. [0003] The traditional metal hose forming method is subject to ...
