Research on the development status of hose crimping machines and pipe presses
Hydraulic hose crimping machine, pipe press machine was originally developed from a press. The early hydraulic hose crimping machine, pipe press machine was backward in technology, large in size, poor in crimping quality, and low in efficiency. At that time, the Hydraulic hose crimping machine, pipe press machine occupied a large area, about 30-40 square meters, and its working efficiency was very low. Hydraulic hose crimping machine, pipe press machine was originally introduced by several major hose manufacturers, such as NRP Corporation in the United States and GATES Corporation in the United Kingdom. With the development of hydraulic pressure towards high pressure and ultra-high pressure, the demand for Hydraulic hose crimping machine, pipe press machine is increasing, and the requirements for Hydraulic hose crimping machine, pipe press machine are getting higher and higher, such as the precision of buckle and hydraulic hose. crimping machine, pipe press machine quality and range of crimping, etc. At this time, there are manufacturers engaged in the production of crimping machines and hose supporting equipment. In foreign countries, a large number of Hydraulic hose crimping machine, pipe press machine emerged in the 1960s and 1970s. For example, Finn-Power Corporation of Finland began designing and producing crimping machines in 1969; UNIFLEX in Germany established crimping machine production lines in 1972; In the United States, CMS was established and became the domestic leader in the field of hose crimping machines. At present, the crimping press technology owned by these companies is at the leading level in the world, especially FINN_POWER in Finland and UNIFLEX in Germany.
In the early 1980s, China began to introduce foreign hydraulic hose crimping machine, pipe press machine products, but because of its high price, such as the hose connector crimping machine JB32 produced by Finland, the price is as high as 120,000 yuan, so some domestic manufacturers have launched crimping machines accordingly. product. For example, Weifang Haidatong withholding machinery developed this technology and equipment in 1994. Its main technical performance reaches the advanced level of similar foreign products, and it is now in mass production. At present, Hydraulic hose crimping machine, pipe press machine has become a series of products that can meet the needs of users working in different environments, suitable for different sizes of hoses and different styles of hose joints.
