Helical blade forming machine

Abstract

The invention relates to a forming machine, and in particular relates to a helical blade forming machine which comprises a base, wherein the upper part of the left side of the base is sequentially provided with a helical blade draught device, a helical blade and shaft rotating device from left to right, the upper part of the right side of the base is provided with a helical blade and shaft supporting device matched with the helical blade and shaft rotating device, and a helical blade screw pitch regulating device is arranged on the base between the helical blade and shaft rotating device and the helical blade and shaft supporting device. The helical blade forming machine has a simple structure and a reasonable design, and is simple and convenient for welding and forming a helical blade, thereby labor intensity of workers is reduced, forming quality of the helical blade is ensured and production efficiency is increased.

Description

Technical field: [0001] The invention relates to a forming machine, in particular to a spiral blade forming machine. Background technique: [0002] At present, for the spiral blades with smaller diameters, the steel strips are directly rolled out. For the spiral blades with larger diameters and thicknesses, due to the greater force and deformation of the spiral blades during the winding process, the discs are usually unloaded first. , and then weld a plurality of discs together, and finally use the reverse chain to pull axially, hammer the worker to make the spiral blade with the required pitch, and then weld it on the spiral blade shaft. The whole production process is complicated and troublesome, and the labor intensity of the workers is high. The size of the screw pitch is not easy to control, the local stress of the helical blade is large, the quality of the produced helical blade is not high, and the production efficiency is low.
