Question 2: What are the standard parts? They refer to the commonly used parts (components) that have been completely standardized in structure, size, pattern and marking and produced by professional factories, such as threaded parts, keys, pins, rolling bearings and so on. Broadly speaking, it includes standardized fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. Narrow sense only includes standardized fasteners. The commonly known standard part in China is the abbreviation of standard fastener, which is a narrow concept, but it does not rule out the existence of a broad concept. In addition, there are industry standard parts, such as automobile standard parts and mold standard parts, which also belong to generalized standard parts.
Guangyi standard component
There are clear standards for mechanical parts. (The main standards used are Chinese National Standard (GB) and American Society of Mechanical Engineers Standard (ANSI /ASME), and other Japanese (JIS) and German (DIN) standards are also widely used internationally.
Mechanical parts with high degree of standardization and strong versatility in the industry are also called universal parts.
Generalized standard parts include fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and so on. , have corresponding national standards, cross-industry versatility.
Industry standard component
This concept belongs to the established statement in the industry and has no clear definition. Standard parts in the industry include mold standard parts, automobile standard parts and so on. When a product is widely used in the industry, it is a universal part; General parts standards are usually formulated by leading enterprises in the industry, and are widely accepted in the industry, making enterprise standards become de facto industry standards, which can also be called industry standard parts.
Mould standard component
Specifically, there are injection mold base, push rod and push tube, hot runner mold and so on.
Automobile standard component
There are many kinds, such as spark plugs, door locks, shock absorbers and automobile fasteners. For details, please refer to the automobile standard parts manual.
The more mature an industry is, the higher the degree of standardization and generalization is, and the more standard parts there are, the lower the industry cost is. However, it is necessary to avoid excessive standardization, which leads to monotonous product categories and low-end competition.
Question 3: How many types of standard parts are there? What do national and municipal standards mean? All items that need to correspond to the standard are standard parts, including fasteners, flanges, gaskets, bearings, pipe accessories, steel pipes, etc. And there are so many. For example, a fastener has:
External hexagon bolt, hexagon bolt, carriage bolt, expansion bolt, locking bolt, U-shaped bolt, self-tapping screw, machine screw, set screw, stud, rack, hexagon nut, nylon nut, metal locking nut, square nut, thin nut, cover nut, butterfly nut, hexagon nuts with flange, rivet nut, round nut, eyebolt, fancy nut, etc. Pipe fittings include: valves, flanges, elbows, stainless steel pipes, etc.
The national standard is the national standard, the city standard, and there is no city standard for fasteners.
Question 4: What do standard parts and non-standard parts mean? Standard parts and non-standard parts.
For example, every brick used in Gai Lou is the same, and there is a national standard, that is, standard parts.
On the contrary, it is not a unified standard, but a small batch of standard non-standard.
Question 5: What does the standard part F593C mean? F593 is not a P steel bolt, socket head cap screw and stud.
Question 6: What do you mean by non-standard? Non-standard means non-standard, and there is no national standard or industry standard to be based on; Standard parts are parts that meet the requirements of national standards and industry standards. There are common parts on the market, which can be repurchased and exchanged at will. At present, manufacturing enterprises are doing non-standard design and standard parts finalization. What else are they designing? But the mechanical principle and other design principles are the same, just combining some standard parts with non-standard parts. No big deal.
Question 7: What do you mean by a thousand standard hardware units? Yu Wenlong, a fastener consultant, thinks that a thousand standard hardware units have two meanings, one meaning is 1000 pieces, and the other meaning is 1000 bags or 1000 boxes or 1000 bags. Yu Wenlong, a fastener consultant, thinks it's best to look up relevant information yourself. Everything I got online was fake. If you don't know how to pretend, you can answer casually. It is simply false or deceptive, which will directly mislead you and even hurt you.
Question 8: What are the national standards and non-standards in standard parts? What do you mean? The national standard is the national standard.
Non-standard is a standard that is not in the national standard.
Question 9: What does standard part FD mean? FD is the wire specification and product category code.
