With the passage of time, the development of processing technology has accumulated experience and technology in failures, and now it has occupied an important position in the market. Technically difficult and complex products such as impellers are also passed. A relentless effort to excel 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 relatively special, its complexity is very large, and its processing difficulty is naturally very large. If there is any error in the process of operation, it will also affect the overall processing progress and effect as a whole. Many people are very curious about the production of this product, so how is the production of impeller processing? Next, let me give you a brief introduction.

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

2. Formulate the process route. Under normal circumstances, the impeller is clamped in 4 times. The first clamping is clamped by a three-jaw chuck, and the second is clamped by a three-jaw chuck. The former can complete the impeller Drilling and rough turning, while the latter is to complete the step circle and step hole on the bottom surface of the impeller. The third clamping can use three-jaw chuck and soft jaw clamping, both of which are almost the same, and the fourth clamping is using a special clamp, which can complete the milling of the impeller to a certain extent.

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

4. Fixture selection, when drilling rough turning, use the blank as the reference, and use the three-jaw chuck for clamping. If the impeller is milled, use the impeller bottom surface and the impeller shaft hole as the positioning reference. Different methods must be used when selecting fixtures. There must be a basis, and you cannot follow blindly.

5. Impeller programming and processing. The impeller processing involved is divided into two processing methods: turning and milling. The difficulty factor of this technical operation is very high, and the program is complicated and difficult to program. It is necessary to have a technician to guide the operation.

To sum up, the above is my preliminary understanding of this product. If you want to know more, please call our Xiehe processing factory.
