As time goes by, the development of processing technology continues to accumulate experience and technology through failures, and now it has occupied an important position in the market. Technically difficult and complex process products such as impellers are also passed Relentless effort comes through in experience. The impeller is the core part of the centrifugal air compressor. To a certain extent, it can convert the mechanical energy of the motor into air kinetic energy and increase the pressure of the output air. However, the structure of this product is quite special, its complexity is very high, and its processing is naturally very difficult. If any errors occur during the operation, it will also affect the overall processing progress and effect. Many people are very curious about the production of this product, so what is the process of impeller processing? Next, let me briefly introduce it to you.

1. Pattern analysis. Before processing, we need to analyze the pattern, analyze its structure, number of parts, degree of distortion, etc., and provide a better plan to a certain extent. In general, the degree of blade distortion is relatively high, and the processing difficulties are the blade surface, flow path surface and blade root fillet. It is very easy to make mistakes at this node, so we have to use small tools for processing, although the efficiency is relatively low. , but errors can be avoided during processing.

2. Develop a process route. Under normal circumstances, the impeller is clamped in 4 times. In the first clamping, it is clamped by a three-claw chuck, and in the second clamping, it is clamped by a three-claw chuck. The former can complete the impeller. Drilling and rough turning, and the latter is to complete the step circle and step hole on the bottom of the impeller. For the third clamping, you can use a three-jaw chuck and soft jaw clamping, both of which are similar. For the fourth time, a special clamp is used, which can complete the impeller milling process to a certain extent.

3. The selection of blank is very important. It has the characteristics of high strength, high hardness and corrosion resistance, but its cutting performance is relatively poor and the dimensional accuracy is not easy to control, so you must be careful during processing.

4. Clamp selection. When drilling and rough turning, use the blank as the benchmark and use a three-jaw chuck for clamping. If the impeller is milled, use the impeller bottom surface and the impeller shaft hole as the positioning benchmark. Different methods must be used when selecting the clamp. You must have some basis and cannot follow blindly.

5. Impeller programming and processing. The impeller processing involves two processing methods: turning and milling. The difficulty of this technical operation is very high. The program is complex and difficult to program. There must be technical personnel to guide you during the operation.

In summary, the above is the editor’s preliminary understanding of this product. If you want to know more, please call our Xiehe processing manufacturer.
