Abstract

본 발명은 용접열에 의해 익형의 날개(6)가 변형을 일으키거나 파손되는 것을 방지할 수 있는 익형 임펠러 제작방법 및 그 방법에 의한 익형 임펠러에 관한 것이다.The present invention relates to a method for manufacturing a airfoil impeller that can prevent deformation or breakage of the blade 6 of the airfoil by welding heat, and airfoil impeller according to the method.

본 발명에 따르면, 박판으로 구성된 다수개의 익형날개의 곡면부(12) 양단에 수평으로 플랜지부(16)을 형성하고, 상기 익형날개(6)의 평면부(14) 양단에 절곡편 (18)을 형성하여, 상기 절곡편(18)이 삽입결합되는 관통홈(20)이 소정의 위치에 형성된 주판(2)과 상판(4)을 상기 절곡편(18)이 관통홈(20)에 삽입되도록 상기 익형날개(6)의 양단에 결합하고, 상기 절곡편(18)을 절곡한 후, 상기 절곡편 ( 18)과 플랜지부(16)를 주판(2)과 상판(4)에 용접결합하는 것을 특징으로 하는 익형 임펠러 제작방법이 제공된다.According to the present invention, a flange 16 is formed horizontally at both ends of the curved portions 12 of the plurality of airfoil blades formed of thin plates, and the bent piece 18 is disposed at both ends of the flat portion 14 of the airfoil blade 6. To form the main plate 2 and the upper plate 4 in which the through groove 20 into which the bent piece 18 is inserted and coupled to the predetermined position is inserted into the through groove 20. After coupling to both ends of the airfoil (6), bending the bending piece 18, welding the bending piece 18 and the flange portion 16 to the main plate (2) and the upper plate (4) Provided is a method for manufacturing an airfoil impeller.
