Automatic seam welding of foreign steel drums in the application and the absorption of the situation

Other expenses, a total of 1.5 million yuan or more, such high costs are prohibitive for the majority of cooperage plant. Localization of the introduction of welding machine sales in 1981, Sinopec Corporation, East China branch of science and technology personnel, refer to the relevant technical information abroad,[link widoczny dla zalogowanych], for the factory production line equipped with a 1 Barrel Taiwan-made drums fully automatic seam welder, and later the United Kingdom The welding machine, 2 sets of re-designed and manufactured. Despite the late date put into normal production, but in exploring the development of our own automatic welding machine has accumulated a lot of useful experience. Since then, many domestic research institutes and professional factory welder made a lot of foreign research and investigation work, the feasibility for the development of domestic welder provides an important basis. It is in this work, based on October 1986 in Nanjing Mining Machinery Factory After a thorough analysis and appraisal, summed up the development work of domestic experience and lessons learned, and the Shanghai Cooperation welding plant proposed digestion and absorption of imported technology solutions welder , Allium immediate concern about the leadership and support. After two years of hard work,[link widoczny dla zalogowanych], dated 1988, lO prototype factory, delivery and Shanghai and Jiangsu diameter Barrel plant use, in June 1989 for a 250-FN-made drums fully automatic seam welder adopted by the organization's identification of China National Packaging Corporation,[link widoczny dla zalogowanych], also began small batch production. Development of automatic seam welder and localization taken a welcome step. FN 250 drums of a capacity of 250 KVA automatic seam welder. Using single-phase AC power supply, the production capacity of 600 pcs / hour, the technical indicators have reached the level of similar foreign welder. Barrel plants under both the facts of extensive use of hot-rolled plates,[link widoczny dla zalogowanych], electric control part of the design has been improved to make up for only the original prototype welding cold rolled plate, hot plate welding of bad domestic shortcomings. Degree of machine-made to 1OO%. Conclusions and Recommendations 1. Strengthen sector management, all domestic manufacturing facilities have the ability to not repeat the introduction, in order to save foreign exchange and domestic packaging machinery industry to promote technological progress. 2. Buy technology, buy less equipment, engage in joint co-production. Can take the lead by the Packaging Corporation, a set of domestic manufacturing of several advantages of welding equipment manufacturers and Barrel,[link widoczny dla zalogowanych], a common external. Enable us to seek foreign partners, give full play to their strengths, to shorten the gap with foreign countries, to open the international market. 3. Supporting the introduction of equipment work. Now the introduction of equipment utilization is not high, to welding, for example, only about 30%, due to the following process is not complete by the constraints. Force should be organized to carry out work on the development of domestic equipment. 4. Rapid development, the development situation of China's steel drum for automatic welding seam. In particular, shall meet: @ low power consumption, capacity control 150kVA) ~ Right; ② wide scope, the diameter range 360 to 600, adjust easily and quickly; @ domestic cold and hot plates can apply; ④ productivity 300 / at about : ⑤ equipment price control in 25 ~ 3O million to small and medium enterprises Barrel affordability.
