Product Description

Production Descreption

Introduction of straightening machines
Series JY straightening machines are high-efficiency machines which are mainly used to straighten precisely and calender metal bars peeled. They can use special curve between the two straightening rolls to straighten and calender bars. The equipment contains main machines, cooling lubricant system , electrical system, transfer system and auxiliary machines. (The pictures are as below.)


Technical Parameter
 

1.Application

The seven roll straightener is used to straighten the bending of bar or tube created in the rolling process. It has obvious effect  in solving bar head or tail bending, eliminating slight ellipticity and removing oxide scale. The material of bar or tube includes Carbon tool steel, carbon structural steel, alloy tool steel, alloy structural steel, spring steel, stainless steel, bearing steel, titanium chromium nickel alloy etc..
 

2.Main Technical Performance Of Equipment

2.1 specification: φ25~80×2000~8000
2.2 yield strength: ≤880N/mm²
2.3 original curvature: ≤5‰(5/m)  Total bending ≤30‰
2.4 Straightening precision: ≤1‰(1/m)
2.5 Straightening speed: 12~20m/min(CVT)
2.6 Max straightening force: 300KN
2.7 straightening roll:

1. size: φ250×380 φ200×290
2. Arrangement: 2-2-2-1
3. Central distance: 520~580mm

2.8 others:

1. floor area: about 8×3.5×2.5m
2. Motor capacity: about 100kw
3. Air consume: 20m³/h
4. Feeding direction: left feeding
5. Standard height of machine: +990(lower roll down surface)
6. Precision measurement: conventional method

 

3.Main Features Of Equipment

3.1 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.
3.2 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.
3.3 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.
3.4 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.
