Introduction to the knowledge of mechanical parts processing that we don’t know

The processing of mechanical parts is an important work content for the mechanical processing plant. It has become one of the operating content of the mechanical processing plant. The previous editor has introduced the related content of mechanical processing for everyone, but those are only small There is still a lot of knowledge waiting for us to understand and learn, because the knowledge contained in it is very rich, and only by continuous learning can we continuously deepen our understanding, so let’s expand on it in detail below. 1. The production process refers to the process of transforming raw materials or semi-finished products into products. It includes the following aspects: The technical preparation process refers to the market research and forecasting, the identification of new products, and the process design before the product is put into production. And standardization review and other content. Process regulations are the process of compiling a reasonable and correct process into technical documents used to guide production, and the specifics are turned into text descriptions. Auxiliary production refers to normal auxiliary production activities, and these production activities are for the smooth progress of production activities. The production service process includes the organization, transportation, storage and storage of raw materials, as well as the sales and packaging of products. 2. The process here refers to the cutting of parts. It contains many processes. Each process includes station, step, and knife, etc., and the division is based on the location and continuity of the work. In the process, the process step is the basic unit that constitutes the process. What is a knife? To put it simply, it is to cut off the margin on the processed surface of the workpiece, but the cut off margin cannot be too much. If it cannot be done at one time, it can be carried out in several steps. In the process, a processing position is called a station. In most cases, the workpiece is only installed once in a process, but sometimes, it may be installed multiple times. 3. The formulation of the process regulations includes the requirements, steps and requirements of the process regulations. Generally speaking, it should be economical and reasonable. The steps of formulating process regulations are: first determine the machine tool used in each process, clamping method, measurement method, machining allowance, cutting amount and working hours quota, etc., and then record these contents in a certain form to make a mechanical processing process card , So that the operator can refer to it. However, the parts are different, so the structure size, accuracy requirements and surface roughness are also different, and the processing technology is also different. There may be several processing schemes, but one of them is definitely suitable. We have to choose. In the selection, it should be able to meet all the technical requirements of the parts, so it must go through a process of repeated modification and gradual improvement, and finally become mature and reasonable.
