As far as we know, a high quality product depends on the excellent design and especially relies on the reliable assurance of the good manufacturing. The good manufacturing has a direct relationship with the perfect processing technologies. Only when people choose the proper processing technologies, the product with the high degree of accuracy will be manufactured. Thus the production cost will be reduced and the production efficiency will be enhanced. Because there are so many kinds of water pump components and their structures are rather complex, it is not easy to control their processing technologies and qualities. Especially for the production model with various breeds and small amount, the working procedure is so concentrated that more comprehensive professional knowledge is needed.
The water pump components have very complex structures. The cast parts account for over 80 percent. They include iron casting, steel casting and stainless steel casting. There are a few shaft parts, only including carbon steel, chrome steel and stainless steel. Because there is water flow passage, the proper position of the flow passage should be found when people consider the base face for positioning the clamp. Or else, it will have a bad effect on the flow passage between pumping chamber and impeller and the quality of the product. Therefore, in order to ensure the accuracy of the components, the relevant clamping should be designed and the technological process will be arranged properly.
In the follow passage, something about the manufacturing technologies about the water Pump components will be introduced in detail. What comes first is about the clamping of the workpiece. Before the people begin to work, they must get familiar with the product design document, process file and technological equipment. Then when people install the holding fixture on the desktop, the locating surface should be cleared and meanwhile the relative position should be found properly. What’s more, the force to fasten the workpiece should be suitable. The working point of the clamping force must be through the supporting surface and near to the working surface. Next, it is about the requirements for the processing. According to the rules about the technology, material, accuracy, knife tool and so on in the document, the operator should select the proper process route and cutting data. Besides, for the size having the tolerances, it should be processed according to the middle tolerance during the process. The burr produced in the working procedure should be removed in the corresponding procedure. In addition, in the cutting process, if there is some abnormal sound, it is better to stop the cutting and check the system carefully. Only the qualified workpiece can be entered the next procedure.
In conclusion, it is reported that a lot of problems about the water pump component are related with the bad manufacturing technologies. From this point, the importance of the technology can not be overlooked. Although the manufacturing technologies are changeable, there are still rules. The main principle to set the technology is as follow: grab the key point-select the standard properly; seize the keystone-adopt the suitable assurance; decide the method-choose the right process route.
