Abstract
The utility model discloses a centrifugal wind wheel with an improved blade, which comprises a diversion ring, a blade plate and blades, wherein the diversion ring consists of a body, a diversion nozzle and an arc-shaped diversion neck; a base which is integrally formed with the diversion ring is arranged on the diversion ring; one end of the base is stopped at the extension surface of the inner surface of the diversion nozzle; the other end is stopped at the surface of the body in a radial direction; a projected head is arranged on the base; the blades are parallel with the welding end surface of the diversion ring and the axial end surface of the body; the projected head is inserted into a front mold core cavity of the blades; and the blades are welded with the end surface corresponding to the diversion ring, the body and the base through ultrasonic waves. On one hand, the arc-shape of the diversion neck joint part of the blades and the diversion ring is changed into a plane so that the height of the blades is relatively reduced; on the other hand, the base is arranged on the diversion neck, the projected head is arranged on the base, and the projected head is inserted into the front mold core cavity, so the centrifugal wind wheel can be welded by the existing ultrasonic welding machine. The utility model overcomes the defects that the existing ultrasonic welding machine has small welding energy and can not be used for welding in the prior art.
Description
Technical field
The utility model relates to a kind of centrifugal wind wheel of centrifugal blower.
Background technique
Present prior art, a kind of centrifugal wind wheel comprises baffle liner, leaf body plate and blade, and leaf body plate and blade are one-body molded to be made, described baffle liner is by body, water conservancy diversion mouth and be positioned at the water conservancy diversion mouth and the arc water conservancy diversion neck of body intersection constitutes, and the part of blade and the welding of water conservancy diversion neck is curved.Existing problems are: especially big to diameter, and the wind wheel that the wind wheel axial length is big, because the curved part of blade is highly big, blade and baffle liner are used present ultrasonic welding machine and can not be welded.
Summary of the invention
The purpose of this utility model is: a kind of centrifugal wind wheel that improves blade is provided, and it can overcome deficiency of the prior art effectively, can use present ultrasonic welding machine welding.
The utility model is achieved in that a kind of centrifugal wind wheel that improves blade, comprise baffle liner, leaf body plate and blade, leaf body plate and blade are one-body molded to be made, the other end of blade and baffle liner welding, described baffle liner is by body, water conservancy diversion mouth and be positioned at the water conservancy diversion mouth and the arc water conservancy diversion neck of body intersection constitutes, its special way is: have on baffle liner and the integrated base of baffle liner, extended surface, the other end that base one end terminates in water conservancy diversion mouth internal surface terminates in the surface radially of body, and a plush copper is arranged on the base; Described blade is parallel with the axial end of body with the welding end surface of baffle liner; Plush copper is inserted in the preceding mold core cavities of blade, blade and baffle liner opposing end faces, and body and base be connected together with ultrasonic welding.
The centrifugal wind wheel of described improvement blade, its special way is: institute's plush copper is by on the axial end that extends to body on the base.
The centrifugal wind wheel of described improvement blade, its special way is: the body of baffle liner has two stiffening ribs with the both sides at the relative position of blade, and the radial outside of blade is positioned at two stiffening ribs and constitutes groove.
The centrifugal wind wheel of described improvement blade, its special way is: the body of baffle liner has two stiffening ribs with the both sides at the relative position of blade, and the radial outside of blade is positioned at two stiffening ribs and constitutes groove; Described plush copper is positioned at the part on the axial end of body, is positioned at groove.
A kind of centrifugal wind wheel that improves blade of the utility model, owing to adopt this spline structure, the water conservancy diversion neck anastomosis part arc with blade and baffle liner changes the plane on the one hand, reduces blades height relatively; On the other hand, at the water conservancy diversion neck portion base is set, plush copper is set on the base, plush copper is inserted in the preceding mold core cavities; Can use present ultrasonic welding machine to weld.Overcome in the prior art, because of the ultrasonic welding machine that uses at present, welding energy is little, the defective that can not weld.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of centrifugal wind wheel that improves blade, comprise baffle liner 2, leaf body plate 1 and blade 3, leaf body plate 1 and blade 3 one-body molded making, the other end of blade 1 and baffle liner 2 welding, described baffle liner 2 is by body 21, water conservancy diversion mouth 22 and be positioned at 23 one-tenth of the arc water conservancy diversion neck structures of water conservancy diversion mouth and body intersection, as shown in Figure 3, on baffle liner 2, have and baffle liner 2 integrated bases 4, extended surface, the other end that base 4 one ends terminate in water conservancy diversion mouth 22 internal surfaces terminates in the surface radially of body 21, and a plush copper 41 is arranged on the base 4;
Described blade 3 is parallel with the axial end of body 21 with the welding end surface of baffle liner 2;
Institute's plush copper 41 is by extending on the axial end of body 21 on the base 4.
As Fig. 3, Fig. 4, shown in Figure 5, the body 21 of baffle liner 2 has two stiffening ribs 211 with the both sides at blade 3 relative positions, and the radial outside of blade 3 is positioned at two stiffening ribs 211 and constitutes groove 212.Two stiffening ribs 211 play the effect of reinforcement protection blade 3 and body 21 welds.
Described plush copper 41 is positioned at the part on the axial end of body 21, is positioned at groove 212.
