Abstract
The machining process specification is the main technical document guiding the production of theworkshop, the important materials for production preparation and management preparation, the basic basis for the construction or expansion of the factory and theworkshop, and the exchange and promotion of advanced experience. The correct process schedule can ensure the quality of the product and obtain high productivity and economic benefits, and the production can be balanced and smooth.
The parts given in this paper are cooling oil pipes,which are one of the typical parts in hydraulic transmission systems. Provides an important path for cooling the hydraulic system circuit. Through the analysis of the parts drawings, trainyourself to establish the correct processing ability for the product, complete the processing and assembly process. Itwill also enableyou to further deepenyour understanding of the theoryyou have learned and learn to use the knowledgeyou have learned to analyze and solve practical problems.
This design has carried out a detailed analysis of the processing procedures of the cooling oil pipe. The machining process routewas formulated, and the machining allowance, cutting amount, machining allowance, processing time, machining, etc.were calculated in detail, and the processing equipmentwas selected. Through this design, master the analysis of the machining process of the parts, the preparation of the process cards and the steps. Learn to apply manuals, standards, specifications and more. Recognize the importance of processes in machine building. Understand the selection rules of tools, product quality, accuracy, life and other attributes and materials, reduce costs, and most importantly improve production experience.
