Problems solved by technology

[0002] The traditional processing technology of the spiral blade is to use a flame cutting machine to cut the steel plate into arc plates of different sizes, then weld the arc plates into flanges, and finally use the stretching method to make spiral flanges. This process obtains The spiral blade itself has multiple welds, which has a great influence on its own structural strength, and its durability is not high, so it is necessary to improve the traditional processing technology

Abstract

The invention discloses a seamless spiral blade machining method. The seamless spiral blade machining method comprises the following steps that S1, a steel plate is cut into a blade base material meeting the width and length dimension requirements, or the blade base material meeting the width and length dimension requirements is directly customized; S2, the blade base material is put into a circling forming machine to be formed and circled, a blade base circle flange is obtained, and the diameter of the blade base circle flange is equal to the diameter of a circle formed by unfolding the spiral blade; and S3, the blade base circle flange is put into a spiral blade forming machine for spiral forming, and the spiral blade is obtained. The spiral blade machined through the steps adopts a cold bending technology, a heating link is omitted, the hardness of the steel plate is guaranteed, meanwhile, the material quality is also guaranteed, the whole finished spiral blade is free of welding seams, any position of the finished spiral blade can reach the flaw detection standard, the durability degree is obviously improved, and the spiral blade is not prone to being bent and distorted.

Description

technical field [0001] The invention relates to the technical field of spiral blade processing, in particular to a seamless spiral blade processing method. Background technique [0002] The traditional processing technology of the spiral blade is to use a flame cutting machine to cut the steel plate into arc plates of different sizes, then weld the arc plates into flanges, and finally use the stretching method to make spiral flanges. This process obtains The spiral blade itself has multiple welds, which has a great influence on its structural strength, and its durability is not high, so it is necessary to improve the traditional processing technology. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a seamless spiral blade processing method. [0004] The technical scheme of the present invention is as follows: a method for pr...
