Specific Description:
steel rod straightening machine
1. Steel rod straightening machine a kind of straightening machine that can straighten different kinds of steels. Main Features Of Equipment
2.7 roll straightening machine adopts optimized hyperbolic and deep-shallow concave composite roll system, which absorbs the advantages of 2 roll and multiple oblique roll straightening machine, at the same time conquers the disadvantage of the two. The precision is high.
3.The principle of rolls against pressing with controllable loading turns the rigid frame is a flexible frame which ensure the necessary pressure imposed on the bar thus enlarge the Plastic range of bar, the result is better straightening precision and little damage to the machine.
4.Main drive adopts AC frequency conversion driving device with stepless speed regulation, constant torque output at base speed, and constant power output above base speed.
5.There is hydraulic station in the Hydraulic system which uses
constant pressure pump as power source. The accumulator can be used for quick oil filling, and the overload unloading adopts a direct acting overflow valve which plays the role of pressure buffer.
