Machining method of conical round steel pipe

Abstract

The invention provides a machining method of a conical round steel pipe. Four V-shaped notches are symmetrically cut at one end of a selected basic round steel pipe to form a closing-in part of the conical round steel pipe. The four V-shaped notches are contracted through an outer sleeve, a wedge and a hammer. The four V-shaped notches are welded together through a welding gun, and thus the required conical round steel pipe is obtained. The machining method of the conical round steel pipe is simple and practical, and the method can be implemented with only a small quantity of common tools. By the adoption of the machining method of the conical round steel pipe, the conical round steel pipe does not need to be purchased or customized in advance. By manufacturing the conical round steel pipe personally, the project cycle can be shortened, and the construction cost can be reduced. According to the machining method of the conical round steel pipe, the standard conical round steel pipe can be manufactured in advance according to requirements, and the non-standard conical round steel pipe with arbitrary angles can also be manufactured so as to meet the field installation requirements, so that emergent installation needs are met; and a production channel of a conical round steel pipe product is provided, and the problems of high energy consumption and pollution in the construction industry are solved to a certain extent.

Description

technical field [0001] The invention relates to a manufacturing process of a variable-diameter steel pipe, in particular to a processing method for a tapered circular pipe. Background technique [0002] In the construction steel structure system, it is often necessary to use conical circular steel pipes to connect two steel pipes with different diameters. Under normal circumstances, this kind of tapered round steel pipe needs to be pre-ordered and specially made by the manufacturer according to the technical requirements put forward by the user. The special tapered round steel pipe increases the project cost, and on the other hand, it also delays the project cycle due to the long scheduled time. In addition, some special-sized conical circular steel pipes are sometimes used in construction, which requires temporary procurement to break the budget. Temporary procurement of these special-shaped conical circular steel pipes not only prolongs the production cycle, but also incr...

Problems solved by technology

The special tapered round steel pipe increases the project cost, and on the other hand, it will delay the project cycle due to the long scheduled time

In addition, some special-sized conical round steel pipes are sometimes used during construction, and it is necessary to break the budget for temporary purchase. Temporary purchase of these special-shaped conical round steel pipes will not only prolong the production cycle, but also increase the construction cost
