Abstract
The utility model relates to the field of ventilating equipment. A centrifugal fan blade comprises a blade body and a guide ring, the blade body is formed by connecting of a blade bottom plate and blades, the guide ring is welded with the blades in a fixed mode through an ultrasonic wave, positioning blocks are arranged on the guide face of the guide ring, inner baffles are arranged on the inner sides of the positioning blocks, and the positioning blocks and the inner baffles are connected with the guide ring wholly. Grooves which are supplied for the positioning blocks to be inserted are arranged on the blades, the number of the blades is seven or nine, and welding wires which are connected with the guide ring wholly are arranged on the guide ring along the edges of the positioning blocks. The centrifugal fan blade has the advantages that the structure is novel, the guide ring and the blades can be rapidly and accurately welded, and firmness of connection is high.
Description
Technical field
The utility model relates to the ventilation equipment field, relates in particular to a kind of centrifugation blade.
Background technique
Centrifugation blade is product commonly used in the ventilation equipment field, and centrifugation blade comprises leaf body and baffle liner, and the leaf body is connected and composed by leaf base plate and blade one, fixes in the groove on the positioning block insertion blade on the baffle liner and by ultrasonic welding.The soldering point Search and Orientation was cumbersome when the deficiency that existing centrifugation blade exists was baffle liner and blade ultrasonic welding, and because the yield rate that the factors such as the fastness of welding and positional accuracy cause processing reduces.
Summary of the invention
The purpose of this utility model is the defective that exists in order to solve existing centrifugation blade, and a kind of novel structure is provided, and baffle liner and blade can weld fast and accurately, and the high centrifugation blade of degree of being connected firmly.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of centrifugation blade comprises leaf body and baffle liner, and the leaf body is connected and composed by leaf base plate and blade, and baffle liner and blade pass are crossed ultrasonic welding and fixed; The guide face of baffle liner is provided with positioning block, and the inboard of positioning block arranges internal baffle, and positioning block and internal baffle all are connected as a single entity with baffle liner; Blade is provided with the groove that inserts for positioning block, and described blade is seven or nine, and the edge along positioning block on the described baffle liner is provided with the weld bond that is connected as a single entity with baffle liner.
As preferably, described weld bond is made of mutually discrete two-part, and wherein a part of weld bond surrounds into U-shaped along the edge of positioning block, and open end is in the outside of baffle liner; The inner of another part weld bond is in the weld bond of U-shaped and towards the outer end of positioning block, and the outer end of another part weld bond is on the edge in the baffle liner outside; The fastness that the weld bond of above-mentioned this structure connects is higher, and weld bond all is in the outside of internal baffle, on the impact of the arc guide face of baffle liner inboard, guarantees guide face air intake water conservancy diversion using effect when preventing ultrasonic welding by internal baffle.
Adopted a kind of centrifugation blade of above-mentioned technological scheme, edge along positioning block on the baffle liner is provided with the weld bond that is connected as a single entity with baffle liner, only needing the fusion welding line that baffle liner and blade are fixedly linked when baffle liner and blade ultrasonic welding gets final product, easy to process and degree of being connected firmly is high, also can not affect designing shape and the structure of baffle liner and blade.The advantage of this centrifugation blade is novel structure, and baffle liner and blade can weld fast and accurately, and degree of being connected firmly is high.

Fig. 2: the schematic diagram of baffle liner among the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing 1 and Fig. 2 embodiment of the present utility model is made a detailed explanation.
A kind of centrifugation blade as depicted in figs. 1 and 2 comprises leaf body and baffle liner 3, and the leaf body is connected and composed by leaf base plate 1 and blade 2, and baffle liner 3 and blade 2 are fixed by ultrasonic welding.Blade 2 is seven or nine.The guide face of baffle liner 3 is provided with positioning block 32, and the inboard of positioning block 32 arranges internal baffle 33, and positioning block 32 and internal baffle 33 all are connected as a single entity with baffle liner 3.Blade 2 is provided with the groove that inserts for positioning block.
Edge along positioning block 32 on the baffle liner 3 is provided with the weld bond 31 that is connected as a single entity with baffle liner 3.Weld bond 31 is made of mutually discrete two-part, and wherein a part of weld bond 312 surrounds into U-shaped along the edge of positioning block 32, and open end is in the outside of baffle liner 3.The inner of another part weld bond 311 is in the weld bond 312 of U-shaped and towards the outer end of positioning block 32, the outer end of another part weld bond 311 is on the edge in baffle liner 3 outsides, and another part weld bond 311 can be that straight line also can be many straight lines of segmentation.Weld bond 31 all is in the outside of internal baffle 33, on the impact of the arc guide face of baffle liner 3 inboards, guarantees guide face air intake water conservancy diversion using effect when preventing ultrasonic welding by internal baffle 33.
