Problems solved by technology

For large fan impellers, the wheel cover has a large size and thick thickness, and the material of the wheel cover has high yield strength. If the integral molding is adopted, the production cost of the mold will be too high, and the production cycle of the mold will be long, and the precision of the mold will be low. Difficult to guarantee, if the spinning machine is used for forming, the requirements for the equipment are too high, and the conventional spinning machine cannot process

Embodiment Construction

[0026] Embodiments of the present invention are further described below in conjunction with accompanying drawings:

[0027] Such as figure 1 As shown, the wheel cover 1 is spliced ​​by four wheel cover parts 2. The wheel cover part 2 is in the shape of a fan ring, and is formed by multiple segmental pressing along the arc direction. The wheel cover 1 is then combined with the wheel The cover 2 and 3 are spliced ​​and formed and meet the requirements. The specific process includes the following steps:

[0028] ① According to the wheel cover parts to be formed, make a flat material 2 times;

[0029] ②Profiling of the plate through the molding die: place half of the wheel cover part 2 on the molding die, and align one end of the wheel cover part 2 with the edge of the molding die, and press the wheel cover part 2 The part placed on the mold is molded until it reaches the qualified size, and then the wheel cover part 2 is rotated along the arc direction, and the press works to p...

Abstract

The invention provides a segmented profiling technology for forming a draught fan wheel cover and belongs to the technical field of draught fan manufacturing. The segmented profiling technology for forming the draught fan wheel cover solves the problems that an existing large-sized draught fan wheel cover is high in production cost, complicated in production and the like. According to the segmented profiling technology for forming the draught fan wheel cover, a first wheel cover body is formed by splicing four wheel cover components, each wheel cover component is in a fan ring shape and is formed through repeated segmented profiling in the arc direction, the first wheel cover body and a second wheel cover body are spliced to form the draught fan wheel cover, and requirements are met. The segmented profiling technology for forming the draught fan wheel cover has the advantages of simplifying the mold design in the manufacturing technology, lowering the production cost, improving the precision of the product, being wide in application range and the like.

Description

technical field [0001] The invention belongs to the technical field of fan manufacturing, and relates to a segmented profiling process, in particular to a segmental profiling process for forming a fan wheel cover. Background technique [0002] The impeller is a key component of the fan, and its structural accuracy directly affects the overall performance of the fan. Most of the wheel covers in the fan impeller are arc-shaped, and the forming mainly depends on the overall molding of the mold or the spinning machine. For large fan impellers, the wheel cover has a large size and thick thickness, and the material of the wheel cover has high yield strength. If the integral molding is adopted, the production cost of the mold will be too high, and the production cycle of the mold will be long, and the precision of the mold will be low. It is difficult to guarantee that if the spinning machine is used for forming, the requirements for the equipment are too high, and the conventional...
