Chain walking all-in-one machine integrating functions of chain feeding guiding, stamping and chain discharging and operation method thereof

Technical Field

The invention relates to a chain walking all-in-one machine, in particular to a chain walking all-in-one machine integrating functions of chain feeding guiding, impressing and chain discharging and an operation method thereof.

Background

With the continuous deepening of the manufacturing industry in China and the assistance of the intelligent and diligent national characteristics of China, various industries are struggling to catch up with the foreign manufacturing industry level of the strong country. Taking the hoist chain industry as an example, under the continuous guidance of the national industrial policy, the whole industry chain is developing vigorously, and the summary is briefly described from the past, the present and the future.

First, the chain industry in the past. Several decades ago, the manufacture of hoisting chain equipment and hoisting chains was mainly concentrated in developed countries such as de-mei days, and the main advantages are that the whole industrial chain (such as steel, heat treatment, surface treatment and the like) starts early, the mechanization degree of the equipment is high, the product standard is used as a guide, and the products are always sold around the world. The 80 th generation of China is improved and opened, the original creators of the first generation of village and town enterprises start to make low-grade chains such as fishing net chains, bundling chains, antiskid chains and the like by hands, old production lines, old equipment and old molds which are eliminated in developed countries abroad are gradually introduced, manual and semi-automatic production is realized, and the technical key points, the production process, the quality management and other factors are gradually mastered, so that the comprehensive guarantee is provided for the development of the later industrial chains.

Second, the current chain industry. From the middle of the 90 s, the self-manufactured imitation equipment in China is formed by eliminating foreign old equipment and improving the structure and the like through surveying and mapping, and the chain industry in China gains a rapid development due to the characteristics of low price, excellent performance, simple maintenance and the like of the imitation equipment, and the product manufacturing gradually transits from a low-grade (30-60 grade) chain to a medium-grade (70-80 grade) chain. Meanwhile, chain equipment in China is developed towards a higher level from imitation abroad, and is more and more close to foreign high-end equipment in aspects of automation, modularization, refinement, operation simplicity, running cost, start-up rate and the like, and some chain equipment surpasses. And the potential head of an external outlet, namely the whole chain production line or a single machine outlet, is stronger and stronger.

According to incomplete statistics, the annual demand of the global low-grade chains is about 5 million T, the annual demand of the national manufacturing quantity accounts for 70%, the annual demand of the medium-grade chains is about 3 million T, and the annual demand of the national manufacturing quantity accounts for 90%; however, the global annual demand of high-grade chains (more than 100 grades and carbon-permeable chains) with high added value and high profit rate is about 1 ten thousand T, the manufacturing amount of China is about 500T, and the percentage is 5%, and the main reason of the phenomenon is that the high-grade chains in China are unscientific in production process, cause unstable performance and difficultly meet the technical requirements of standard specifications no matter according to the national GB/T20947 standard or the international ISO3077 standard.

And thirdly, the future industrial trend. With the development of the human society and the technological level, the demand of products is certainly to be developed to a higher level, and the demand of the hoisting chain is also certainly to be larger and larger in the future, wherein the demand is partially dependent on the conversion of medium-grade chains. Meanwhile, with the degradation of the population dividend of China, the limitation of policies such as land use, environmental protection and the like and the improvement of cost, the low-level and medium-level chain production is bound to be transferred to the developing China such as southeast Asia (which can be obviously seen from the trend of chain equipment exported by people), the low-level and medium-level market competition is certainly more violent, and the industrial advantages and prospects of China face severe challenges. In conclusion, how to get to the high point of industry and how to get to a cake with high-grade chains is an urgent task in front of us.
