| Processing efficiency of tube expanding machine
Selection of pipe expanding hot expansion tubes of production skills, thermal expansion tube steel tube two step push pipe expander cone die swell skills, intermediate frequency induction heating skills, hydraulic skills, skills and reasonable, low energy consumption, low construction investment, raw materials and goods standard broad adaptability, flexible simple low adaptability in batch process, replace the steel pipe industry traditional drawing skills. Because it is difficult to deal with the supply of large-caliber steel pipes in recent years, the hot expansion pipe has become the main commodity source of the shortage of large-caliber steel pipes, which solves the serious supply situation of large-caliber steel pipes in the market. The fine rolling process of ENLARging the diameter of steel pipe by oblique rolling or RAFting can increase the steel pipe in a short time and produce special seamless pipe with standard cost, low cost and high production efficiency, which is the development trend of the world's pipe rolling scope.
At present, various types of variable diameter steel pipes are used in industrial and agricultural production fields. For example, a car fuel tank is one of them. This variable diameter steel pipe is made by cold working an equal diameter steel pipe by kneading and expanding. For a long time, steel tube expansion is processed by choosing punch or hydraulic press, but there are many problems in this method. For example, the impulse and speed are difficult to control, and the rupture rate of the tube expander is very high. According to the production needs, combined with the actual situation, choose hydraulic technology to develop a new type of hydraulic pipe expanding machine.
In order to improve the production capacity of pipe expander and increase economic benefits, many companies are committed to improving the operation of pipe expander. The new pipe expander selected so far adds two main hydraulic cylinders on the original basis, so that the promotion operation is changed from the original two steps to one step. A set of roller clamping equipment is added to make the material preparation operation more simple and greatly save time. Through the improvement of pipeline expansion machine, further improve the structure and operation function of pipeline expansion machine, with low capital, high power, stable operation, simple operation, convenient maintenance and other characteristics, can meet the company's production requirements and functions, reduce capital, improve economic benefits.
Tube expanding machine is the main equipment for making steel pipe, welcome the consultation of steel pipe industry!
