Craft is short for arts and crafts. Usually refers to the practical art of daily necessities and decorations with obvious aesthetic factors after artistic treatment in external form. It is based on the existence of "craft" and "art". Technology refers to the work, methods and skills of making materials or semi-finished products into finished products through artistic processing; Art refers to the art of shaping a visible plane or three-dimensional image with certain substances, so that people can appreciate it through vision; Arts and crafts refers to the art of making various articles with the methods and techniques of artistic modeling design and color decoration. Craft originated from the time when human beings began to make tools, which is the direct evidence of human origin. Marx pointed out in Das Kapital: "The technological society reveals the dynamic relationship between man and nature, the direct production process of man's life, and the direct production process of man's social living conditions and the resulting spiritual concepts." Most handicrafts are directly created by working people and are one of the basic forms of people's artistic creation. As an art, it was separated from handicraft production and formed as an independent department. Gorky said in Literature: "The founders of art are potters, blacksmiths, goldsmiths, weavers, painters and tailors, generally speaking, craftsmen. Their exquisite works delight us, and they fill the museum. " It can be seen that craft is a beautification skill activity for modeling and decoration of handmade products, and it is a craft culture directly related to material production formed in history.
Question 2: What does the process equipment include? Process equipment includes reactors, towers, heat exchangers, containers, heating furnaces, pumps, etc.
Generally speaking, tooling is something exclusive to a product. For example, in the stamping workshop, the mold belongs to the tooling (the mold can only produce the corresponding stamping parts) and the oil press belongs to the equipment (the oil press can hold different molds for production); Welding fixture for welding belongs to tooling (welding fixture can only be used for a certain welding assembly), and electrode holder belongs to equipment (electrode holder can be used as long as it is suitable).
Fixture is a kind of fixture, which is not only used for welding, but also useful in machining. Many times, when you need to assemble several parts and ensure their accurate positioning, you need to use it.
The design of the fixture should be closely related to the product, because the fixture is specially designed for some products, and it is necessary to ensure that the production does not interfere, the positioning is accurate, and the operator is convenient to operate.
Simply put, it is a tool for clamping workpieces.
Fixture is a kind of special equipment or tool, which is used to clamp or position the workpiece in machining to meet certain technological requirements.
Question 3: What are the process specifications of the process equipment? It is a technical document to guide the construction. Generally, it includes the following contents: the process route of parts processing, the specific processing content of each process, the basic cutting quantity, the man-hour quota, and the equipment and process equipment used.
Process equipment refers to various tools used in product manufacturing. Including cutting tools, fixtures, molds, measuring tools, checking tools, auxiliary tools, fitter tools and workstation appliances. , called tooling.
Question 4: What are the technological equipment in machinery manufacturing? Mechanical manufacturing is divided into several stages:
Blanking stage:
If a special blank is needed, a casting or forging process is needed. This requires a foundry, and the traditional process is turning sand. Coke oven, electric furnace, air hammer or large hydraulic press are often used in forging workshop, of course, cold heading machine can also be used;
Mechanical processing stage:
Then there is mechanical processing, which is traditionally nothing more than turning, milling, planing, grinding and clamping. Now many enterprises have introduced CNC machining centers, which can replace turning, milling, planing and other processes. If it is a sheet metal part, you need shearing machine, bending machine, stamping equipment, punching machine and so on.
Heat treatment stage:
After the mechanical processing is completed, if there are requirements for the hardness of metal materials, heat treatment is needed. Heat treatment equipment includes electric furnace, salt furnace and quenching tank;
Surface treatment stage:
Finally, the surface treatment stage requires pickling first, and then plastic spraying, painting, electroplating, bluing or anodizing can be carried out.
For standard parts, skeleton production line is usually used for mass production.
Question 5: In the process of mechanical manufacturing, what does process equipment (tooling) mean? Process equipment referred to as "tooling" refers to all kinds of tools, fixtures, measuring tools, molds, auxiliary tools, station appliances, etc. Achieve the requirements of the process specification. The purpose of using process equipment; Some are essential for manufacturing products, some are to ensure processing quality, some are to improve labor productivity, and some are to improve working conditions.
Question 6: What is process equipment? Process equipment is a general term for processes and equipment in various labor processes, and it is a necessary condition for completing a product.
Technology is a method and process in which workers use production tools to value-add or process various raw materials and semi-finished products, and finally make them into finished products.
Equipment is the general name of artificial materials and material materials that can be used for a long time in production and basically maintain the original physical form and function in repeated use.
Question 7: What does advanced manufacturing technology mainly include? 1. rapid prototyping technology. Representative product: 3D printer.
2. NC manufacturing and interoperability: NC layout and blanking: NC cutting; Computer aided analysis and simulated pouring; Computer aided process planning.
3. Computer integrated manufacturing system
4. Concurrent engineering. And the synthesis of design.
Wait a minute.
Question 8: Who made the list of process equipment? What are the requirements? The process and tooling are determined according to the actual situation of each company. Each company's equipment, personnel quality, processing procedures are different, and the technology and tooling equipment used are also different. Process is the guarantee of quality, and the general company's process is not open.
Question 9: What are the fixtures in machinery? Tooling, also known as fixture, has many kinds and different functions, but it is mainly used to fix the parts to be processed. So as to facilitate accurate machining and low-precision and small-error drilling.
Question 10: What are the classifications of tooling? What is the definition of assembly tooling and where is it used? In addition to the machine itself, it can also help the workpiece to clamp, accurately locate and fasten firmly, and ensure the machining accuracy. Machining curves and surfaces. Fixtures and adjustment auxiliary tools that are helpful for workpiece assembly and positioning. Special testing tools that can't be detected by conventional measuring tools. Auxiliary tools that can improve work efficiency, etc., all belong to tooling. All types of work have universal and special fixtures, and the range of fixtures is too wide. There are special books and manuals that will give complete answers. This place is full of crap. Don't be serious.
