Straightening machine is a metalworking process used to correct size inadequacies of rolled, drawn or extruded ferrous and non-ferrous materials. It is a form of rolling in which material is alternately bent around a number of sets of work rollers. The bends cause the material to stretch and compress above and below its yield point in a way that reduces internal stresses and homogenizes those that cannot be removed.
There are several different types of metal straightening machines. These machines vary in the number of work rollers, their diameters and the distance between the center of each set of work rollers. Each type of straightening machine has its own advantages and disadvantages. For example, a five-roll straightening machine has a greater capacity for deformation than a three-roll straightener. However, a five-roll straightening machines also has a higher operating cost due to the need for a greater amount of power to move the rolls.
The straightening machine design must be matched to the material and process requirements in order to achieve effective and consistent results. The specifications for a straightener must be carefully defined in order to properly specify the equipment required for a given application. This ensures that the straightener will be able to deliver high production efficiencies and improve product quality.
In addition, the equipment must be correctly sized for the desired production speeds and line conditions. For example, the maximum straightening force, pinch roll pressures, drag brake strength and work roll depth settings must be selected carefully in order to ensure the desired production speed and straightness.
Besides these factors, the straightening machine must also be designed to handle the specific characteristics of the material being processed. For example, if the machine is being used to straighten copper tubes, it must be designed with a large number of plastic cyclic deflections in order to avoid any residuals in the tube. Similarly, if the straightener is being used to straighten solid bars or hollow profiles, it must be designed according to the specific needs of that particular application in order to achieve optimum results.
In addition, the straightening machine must be easy to operate and maintain. This will minimize downtime and maintenance costs and will allow the operator to focus on the production of quality products. MKES has a wide range of straightening machines to suit the needs of any steel or metal industry. These are engineered by expert engineers using the latest technology and top grade raw materials. The range includes straightening machines for angles, channels, flats and I-beams. These machines are ideal for straightening any rolled, drawn or extruded metals in cold condition.
