Problems solved by technology

Since the blade itself is already closed and formed at one time, when it is installed in the fan, it can only be welded on the outer edge of the blade. Greater force, so the blades are very easy to open welding, which will cause unnecessary danger and cause unnecessary losses to the country and people

Embodiment Construction

[0010] Concrete steps of the present invention are:

[0011] a. First, use a plate rolling machine to press the steel plate into an arc with a hook at the front end, as the working surface, weld the reinforcing rib on the concave surface of the working surface, and the hook at the front end of the arc-shaped working surface is a Li-shaped solid body;

[0012] b. Then assemble the working surface on the front and rear discs of the impeller, fix it by spot welding first, adjust the position, and then weld all the contact parts of the working surface and the impeller in all directions, that is, on the double All surfaces are welded;

[0013] c. Then weld the arc-shaped non-working surface to the working surface and the front and rear discs of the impeller, so that the working surface and the non-working surface are combined into an airfoil-like blade.

[0014] There is wear-resistant material on the surface of the blade.

[0015] The finished shape of the blade of the present i...

Abstract

The invention relates to a method for producing fan blade wheel, wherein it comprises: a, first using rolling machine to compress the steel plate into arc shape whose front end has hook, as the working surface, and the concave of working surface is welded with strengthen bar; b, mounting the working surface at the front and back discs of blade wheel, to be fixed by point welding, then adjusting position to weld all contact parts between the working surface and the blade wheel, that welding two surfaces of them; c, welding the arc non working surface on the working surface and the front and back discs of blade wheel. The invention blade has the shape as the wing of plane, which comprises a blade working surface, a non working surface, a strengthen bar and the solid at the end of working surface.

Description

Technical field: [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a manufacturing process of a fan impeller. Background technique: [0002] At present, fans are widely used in all walks of life, especially large-scale fans. However, the manufacturing process of the blades of the existing wind surface impeller is: firstly, all the blades are welded on the outside, and then welded on the inside the fan. Since the blade itself is already closed and formed at one time, when it is installed in the fan, it can only be welded on the outer edge of the blade. Greater force, so the blade is very easy to open welding, thereby causing unnecessary danger, causing unnecessary losses to the country and the person. Invention content: [0003] In order to solve the above problems, the present invention provides a manufacturing process of a fan impeller that can increase multiple welding points. [0004] Concrete steps of the present inv...
