Basic knowledge of die fitter
Introduction to the bench The fitter is the method of machining by hand. 2. The characteristics of the bench has three major advantages, flexible processing, processing complicated shape and high precision parts, small investment), two big weaknesses (low production efficiency and the intensity of labor and processing quality is not stable). (1) working flexibly in a machine that is not suitable for machine processing, especially in the maintenance of mechanical equipment, the work of the fitter is satisfactory. (2) for processing complicated shape and high precision parts skilled bench can work out better than modern machine tool parts processing precision and the bright and clean, can work out the shape of even modern machine tool will not be able to process the complex parts, such as high precision measuring tool, mould, beginning complex, etc. (3) the equipment and equipment used for the processing of small fitter are cheap and convenient to carry. The production efficiency is low, the labor intensity is large
4. The fitter species along with the development of mechanical industry, the widening scope of work bench, professional division of labor is more thin, so is divided into ordinary fitter fitter (assembly fitter), repair bench, die locksmith tools (bench) and so on. (1) the general fitter (assembly bench) is mainly engaged in the assembly and adjustment of machinery or parts, and the clamping of some parts. (2) the repairman mainly engages in the maintenance of various kinds of machinery and equipment. (3) tool fitter (tool manufacturing fitter) is mainly engaged in the production of moulds, tools, measuring tools and samples. 5. Fitter basic operation skills including line, chisel cut cut cut (), sawing, drilling, reaming, counter boring, reaming, tapping and set of silk, straightening and bending, riveting, scraping, grinding, and basic measuring skills and simple heat treatment, etc. Either fitter, first of all should grasp the fitter in all kinds of basic operation skills, and then according to different division of labor further study to grasp the good parts of the bench processing and assembly of products and equipment, repair and other skills. Fitter skills require strengthening basic skill practice, strict requirement, standard operation, practice and innovation. Basic operation skills are the basis of production, is the basis for the machinist's professional skills, therefore, must first master, can be achieved step by step in the future work with ease, with ease.
The work of the fitter is very extensive. There are main lines, machining parts, assembly, equipment maintenance and innovation. (1) underline the parts before processing. (2) the processing parts of the mechanical method is not suitable or cannot solve the parts and all kinds of worker, clamp, measuring tool and a variety of special equipment manufacturing, such as to be done through bench work. (3) assembly of good machining parts according to the technical requirements for components, precision machinery parts assembly and final assembly, making it a complete machine. (4) the maintenance of mechanical equipment in the process of using a case of damage, failure or use for a long time to the bench after losing the use of precision parts for maintenance and repair. (5) to improve the productivity and quality of the products, the innovation and improvement of tools and processes are also important tasks for the workers. In short, the fitter is an indispensable part of the machinery manufacturing industry.
