Description
Technical field
The present invention relates to fastening bolt technical field more particularly to a kind of fastening bolts.
Background technique
Fastening bolt is one kind of machine components, the cylindrical threaded fastener of adapted nut, by head and screw rod
(having externally threaded cylindrical body) a kind of fastener dimerous, need to cooperate with nut, have for being fastenedly connected two
The part of through-hole, this type of attachment claim to be bolted, and can screw off nut from bolt, and can make the two parts point
It opens, therefore being bolted is to belong to be detachably connected, advanced bolt is high-end machine-building sheet, and effect can be " 4 two groups for meaning
It is very heavy ", the bolt output value only accounts for a few percent of machinery industry on surface, and substantially, it brings the additional of key member and equipment
Value wants much higher, and for many years, Chinese bolt is after the growth of continuous double figures, and negative growth occurs in bolt industry within 2012, on year-on-year basis
Decline 1.5% or so, main cause are market demand deficiencies, and especially bolt is after by international anti-dumping, export sales
Volume moves towards brand operation in decline situation, bolt Market competition.
Nearly 10 years, Chinese bolt development speed attracting people's attention while enabling developed country be shocked, also allowed them
It was found that a novel big market, trans-corporation enters in single file.When inner bolt enterprise of state feel to survive on the market suddenly as
When this is difficult, strong rival is in full flourish, the market of China Today bolt, and some middle-size and small-size bolt enterprises are a large amount of
Common standard part is manufactured, there is no really core competitiveness is brought for enterprise, is limited by the conditions such as raw material, human cost instead
Variation, grade low-intensity or 8.8 grades are to 12.9 grade high-strength bolts, the production technology level of Chinese bolt from 4.8 grades to 6.8
It will be measured big inexpensive substantially close to advanced international standard, the predominantly special type of common standard part and low, middle class, heterotypic bolt.Generally
Include and be full of leading market for low-grade product, top grade, high-precision, high-strength bolt have sub-fraction to still need to import, product into
The ratio difference of mouthful unit price and bid is away from about 6 times or more, it is seen then that and Chinese bolt industry is still industry in development, " greatly without strong ",
" fat without strong ", it is larger with the gap of the U.S., Japan, South Korea and China Taiwan, and lack from technological service to the machine of solution
Tool fastening schemes, realize product, design, manufacture and management digitlization, the greenization of product and manufacturing process, it is reported that, in
The development of state's bolt is increasing by the pressure of resource and environment, and the important channel for alleviating resource constraint is development green system
It makes, the development of bolt, one period will also continue to actively push forward towards the direction of brand operation from now on, promote bolt project development
It is comprehensive.
Current bolt effect is single, and when bolt is fixed, ability after needing to dismantle the fixture nut at screw rod end
Bolt is screwed out from bolt head, but in a practical situation, it is difficult to carry out the dismounting of bolt in many cases, is the operation of worker
It makes troubles.
