Question 1: What does "process flow" mean? Process flow refers to the arrangement of various processes in the production of industrial products from raw materials to finished products.
1 Picking materials - 2 Removing materials - 3 Punching - 4 Bending - 5 Welding - 6 Grinding - 7 Inspection - 8 Plastic spraying - 9 Semi-finished product inspection - 10 Warehousing.
Spraying process: spray primer → topcoat → varnish → bake (180-250℃) → quality inspection.
Machining process: blank into warehouse - blank Processing-finishing-semi-finished product inspection-installation-finished product inspection-packaging-logistics
Question 2: What is the process flow, what is the working principle? The process flow refers to the production of industrial products, from raw materials to finished products. The procedures for arranging various processes. Also called processing flow or production flow. Referred to as process. The working principle is the basic law of work.
Question 3: What is the production process 1. The production process refers to the overall process of manufacturing products by an enterprise, including process, process parameters and process formulas, etc. The operation method refers to the use of production equipment by workers to Methods for processing raw materials, parts or semi-finished products in specific production links.
2. The production process refers to the quality and quantity of starting raw materials and packaging materials required to produce a certain number of finished products, as well as the process, processing instructions, and precautions, including one or more control points during the production process. Set of documents.
3. Production technology refers to the methods and technologies of production and processing, which mainly includes technological processes and other contents. Advanced production technology is the basic guarantee for producing high-quality products and improving economic benefits. Use high technology to transform traditional equipment and production technology It is the fundamental way to improve the international competitiveness of traditional industries.
Question 4: What is the role of process flow in production? Process procedures (process flow) are the experience summarized from long-term production and scientific experiments, formulated based on specific production conditions, and continuously improved through production practice. and perfect. Having process procedures will help ensure product quality, guide production work in the workshop, facilitate planning and organizing production, and give full play to equipment utilization. Process regulations are disciplinary documents that all production personnel should strictly implement, certify and implement. Production personnel are not allowed to violate the process regulations or arbitrarily change the contents stipulated in the process regulations, otherwise it will affect product quality and disrupt production order. Hope it helps.
Question 5: What are production technology, production technology, and production process? What is the difference between these three? I personally think this is the difference. I hope it will be helpful to you.
Production technology: It is mainly a special plan prepared by the manufacturing industry in order to coordinate the rational use of effective resources and various related production technologies and focus on technical aspects to ensure that it can better play a good guiding role in the production process.
Produce Craft is a method and process in which workers use production tools to perform value-added processing or processing of various raw materials and semi-finished products, and finally turn them into finished products.
Production process (Technological process): a program that arranges various processes from raw materials to finished products. It consists of two or more business steps to complete a complete business behavior process, which can be called Process; note that it is two or more business steps.
Question 6: What is the ordinary quenching process? What is the process flow? A metal heat treatment process in which the metal workpiece is heated to a certain appropriate temperature and maintained for a period of time, and then immersed in a quenching medium for rapid cooling. Commonly used quenching media include brine, water, mineral oil, air, etc. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, measuring tools and parts that require surface wear resistance (such as gears, rolls, carburized parts, etc.). Through the combination of quenching and tempering at different temperatures, the strength, toughness and fatigue strength of the metal can be greatly improved, and the coordination between these properties (comprehensive mechanical properties) can be obtained to meet different use requirements.
In addition, quenching can also enable some special properties of steel to obtain certain physical and chemical properties. For example, quenching can enhance the ferromagnetism of permanent magnet steel and improve the corrosion resistance of stainless steel. The quenching process is mainly used for steel parts. When commonly used steel is heated above the critical temperature, all or most of its original structure at room temperature will transform into austenite. The steel is then immersed in water or oil and rapidly cooled, whereupon the austenite transforms into martensite. Compared with other structures in steel, martensite has the highest hardness. The purpose of steel quenching is to transform all or most of its structure into martensite to obtain high hardness, and then temper it at an appropriate temperature so that the workpiece has the expected performance. The rapid cooling during quenching will generate internal stress inside the workpiece. When it reaches a certain level, the workpiece will be distorted, deformed or even cracked. A suitable cooling method must be selected for this purpose. According to the cooling method, the quenching process is divided into four categories: single liquid quenching, dual medium quenching, martensite graded quenching and bainite isothermal quenching.
Important factors of quenching effect, hardness requirements and detection methods of quenched workpiece:
The hardness of quenched workpiece affects the quenching effect. The quenched workpiece generally uses a Rockwell hardness tester to test the HRC hardness. Quenched thin hard steel plates and surface-hardened workpieces can be used to test the hardness of HRA. For quenched steel plates with a thickness less than 0.8mm, shallow surface quenching workpieces and quenched steel rods with a diameter less than 5mm, a surface Rockwell hardness tester can be used to test the HRN hardness.
Question 7: What is the process flow of spinning? Blowing carding (combing) and drawing roving and spinning yarn winding
Question 8: What are the similarities between the work process and the process flow? The difference is that the workflow refers to the procedures for people to do things. For example, if your company is developing a new product, the first step is to do what, who will do it; the second step, what to do, who will do it..., at each step Among them, there are work procedures. For example, if you have completed the design drawing of a part and need to issue it, you must go through the procedures of proofreading, review, standardization review, process review, approval, etc. This is the work process.
The process flow refers to the process required for a certain part in the production and manufacturing process.
For example, if your design drawing is a sheet metal part and has been issued, the process flow is blanking - punching - bending - deburring - cleaning - cleaning - spray painting - drying Wait.
Question 9: What is the process flow of drawing frame? The main tasks of the drawing process are:
(1) Merging: combine 6-8 slivers and feed them The draw frame makes a cotton sliver. Since the thick and thin sections of each cotton sliver have the opportunity to overlap with each other, the unevenness of the long segments of the sliver is improved. The weight unevenness of raw strips is about 4.0%, and the weight unevenness of cooked strips should be reduced to less than 1% after merging.
(2) Drafting: that is, the sliver is stretched and thinned to the original level, and the condition of the fiber is improved through drafting, so that the hooked and curled fibers can be further straightened and parallel, and the small cotton bundles can be further separated into single fibers. By changing the draft ratio, the quantitative control of the cooked sliver is effectively carried out to ensure that the weight deviation and weight unevenness of the spun yarn meet national standards.
(3) Mixing: The repeated merging method is used to further mix the single fibers to ensure that the mixed cotton content of the sliver is uniform and the yarn quality is stabilized. Since the dyeing properties of various fibers are different, slivers made of different fibers are combined on the draw frame to fully mix the various fibers. This ensures that the number of fibers on the cross section of the yarn is more evenly mixed and prevents the dyeing process from occurring after dyeing. An effective means to produce color difference, especially when blending chemical fiber with cotton.
(4) Sliver forming: Place the cotton slivers produced by the draw frame into regular circles in the sliver can for easy transportation and storage for use in the next process/
