Fasteners are indispensable industrial necessities in daily life: very small fasteners used in cameras, glasses, clocks, electronics, etc .; general fasteners for televisions, electrical products, musical instruments, furniture, etc .; for engineering, construction For bridges, large fasteners and nuts are used; for transportation appliances, airplanes, trams, and automobiles, large and small fasteners are used together. Fasteners have important tasks in industry. As long as there is industry on the earth, the function of fasteners will always be important.
There are many types of fasteners, whether they are very small fasteners for spectacles or large fasteners for large heavy electrical projects. The main purpose is to use a high degree of industrial products to form a fixed body. If the teeth often occur during use If it is not tightly attached to the teeth, the head of the fastener will break off if it is tightened too tightly, or if the tooth pattern is poor and the lock is not tight. Fasteners are "quantity products", not hand-made artworks. In mass production, they are aimed at achieving high-precision, stable quality and popular prices for consumers. The precision of fasteners is usually 6g (2nd grade, American specification "IFI" is 2A teeth), and the coarse screw used in construction engineering is 1g grade (3rd grade, "IFI" is 1A teeth).
In the industrial fastener market, the most successful exporters meet these three conditions: never export unqualified products; recognize and control non-production costs; the basis for managing production should be based on the products consumers want to buy rather than those Products that are easy to produce. ”
If Chinese companies want to export industrial fasteners to the United States, it is important to understand the differences between China and the United States. The United States is a consumer-oriented society, and many countries in the world are producer-oriented societies in my opinion. In producer-oriented society, it is often the producer who rules the buying and selling rules. In a producer-oriented society, consumers or customers passively buy products because there are more consumers than producers. Recognizing that the United States is a consumer-oriented society, Chinese manufacturers will have the greatest export opportunities. The most successful exporters in the industrial fastener market will be those: 1. Never export unqualified products; 2. Recognize and control non-production costs; 3. Produce what the consumer wants to buy, not produce those Products that are easy to produce. In a consumer-oriented society, consumers dominate the buying and selling rules. Consumers buy products based on other cognitive values, not just product prices. Consumers expect products to meet or exceed quality standards, and returns are considered unreasonable and unacceptable. Consumers hardly have to wait in line, and some consumers actually prefer more expensive products because they feel that their quality will be better, even if there is no better quality.
The vast majority of mechanical parts are made of carbon and alloy structural steel. When turning these materials, they often form band-shaped chips. In order to remove the chips from the blank, the blade needs to bear a huge load. The removed chips quickly slide out from the rake face of the blade. During the relative movement with the blade, it generates a high friction surface and forms a high temperature. Therefore, the blade material not only needs to Wear-resistant, but also to withstand high temperatures, maintain hardness at high temperatures. Therefore, for cutting such materials, P-type cemented carbide with a large proportion of TiC + TaC should be selected. Nowadays, in order to improve the cutting efficiency; the cutting speed; the feed speed is getting higher and higher, and the P-type cemented carbide blades are not competent. In the middle of the last century, people developed a layer of high hardness on the P-type hard blade, called coating. The thickness of the coating is only about 0.2% of the thickness of the blade, which can greatly improve the life of the blade and can adapt to higher cutting speeds. Over the past few decades, the coating technology has also been continuously developed, such as from a single layer to multiple layers or even nano-multilayers; the thickness has also increased from a few μm to more than a dozen μm, and even more. More and more advanced; the cemented carbide as the base material has also developed from a single isotropy to a structure with tilt performance that meets the processing requirements.
For sintered tool materials, there is a possibility of bonding and sintering wear, but the main thing is the chip bonding that is firmly bonded to the surface of the tool. The sintered material and the built-up edge are forced after the subsequent processing impact It is separated from the surface of the tool. In the process, the parts of the tool are also taken away at the same time to cause adhesion, fusion defects and damage, so the bonding and fusion of chips should be avoided as much as possible in the field processing. Of course they also affect the quality of the processed surface. Poor thermal conductivity of sintered materials is prone to damage such as thermal cracks. For continuous cutting and very stable cutting conditions, UE6005 with higher hardness and wear resistance can be further selected. At this time, the impact load is small or no, and it is easy to achieve more efficient cutting at the recommended higher cutting speed.
