Abstract

DC60 (13/11/15) This invention aims to provide a highly responsive crest / contour control function to the press. That gives the response of the device folded down Slower than that of the device folds up even under the condition That makes the folding force rolled down to action In making this objective effective Before starting ironing Both the upward and downward folding force will act and the force that comes together. Caused by rolling force That fits well with the balance rolling force will act on the shock absorber of the ball tapping the workpiece. At the start of the ironing moment, the downward force is maintained while the force changes with the fold upward. And the forces that come together Which consists of the folding force (folding force) as specified, will be performed on the chokes of the rolling piece to be rolled At the end of ironing, the upward folding force returns to the Status before starting ironing And the force that comes together with the downward force It is composed of a folded force that fits together with a balanced rolling force. Will be done with the chokes of the rolling piece in that state will end the rolling Revised Invention Summary 11/11/2015 This invention aims to provide a highly responsive crest / contour control function to the press. That gives the response of the device folded down Slower than that of the device folds up even under the condition That makes the folding force rolled down to action In making this objective effective Before starting ironing Both the upward and downward folding force will act and the force that comes together. Caused by rolling force That fits well with the balance rolling force will act on the shock absorber of the ball tapping the workpiece. At the start of the ironing moment, the fold force is maintained while the force changes with the fold up. And the forces that come together Which consists of the folding force (folding force) as specified, will be performed on the chokes of the rolling piece to be rolled At the end of ironing, the upward folding force returns to the Status before starting ironing And the force that comes together with the downward force It is composed of a folded force that fits together with a balanced rolling force. Will be done with the chokes of the rolling piece in that state will end the rolling -------------------------------------------------- ------- This invention aims to have the function of building control. Crown / shape High responsiveness to the press That gives the response of the device folded down Slower than that of the device folds up Even if under the conditions That makes the folding force rolled down to action In making this objective effective Before starting ironing Both the upward and downward folding force will act and the force that comes together. Caused by rolling force The balance is applied to the shock of the ball rolling the workpiece. At the start time of ironing, the downward force is maintained while the folding force is changed. And the forces that come together Which consists of the folding force (folding force) as specified, will be performed on the chokes of the rolling piece to be rolled At the end of ironing, the upward folding force returns to the Status before starting ironing And the force that comes together with the rolling force The balance is applied to the chokes of the rolling mill in that state, it will end the rolling.

Claims (3)

1. A method for smoothing of rolled metal products, which is done by using an ironing machine with a folding device. Is the building up of the folding force And the down device creates the downward force and where the downward device responds more slowly. Compared with the aforementioned folding device, the method of smoothing rolled metal products. Where there is a characteristic that Before starting ironing There will be both the folding force up and the folding force down and the folding force is equal to the rolling force balance. In a form that is strong together To deal with the chokes of Roll the workpiece, then at the start time of rolling The fold force is maintained at the level of the downward folding force in the Ironing as required. And in the meantime It causes a change in the folding force and makes the folding force of the ball rolling the workpiece in the required rolling. Come to act on the chokes of the workpiece in the form of force together, during the rolling will be rolled to maintain the folding force of the rolling workpiece in the rolling as specified by the method to control the folding force. And after At the end of ironing Will cause Change in folding force Iron That fits well with the balance rolling force To act on the chokes of the rolled workpiece in the form of force, together with the folding force and finish rolling of smooth rolled metal products. 2. Rolling method of smooth rolled metal products As set out in claim 1, where there is a characteristic that is to be rolled with an extruder, where the press is further assembled with an upper roller. And a pair of bottom and one pair of lower and upper supports That supports the rolling mill in order, having a structure in which Hydraulic cylinder fold up Which is a piece to create a folding device for the upper body press And the aforementioned bottom Will be built into the protruding block. Which it will extend into Inside the frame of the press And the hydraulic hose is stationary It is connected to the hydraulic control valve. Of the hydraulic cylinder folded up, and besides, it will have a structure in which Hydraulic cylinder fold down That creates the device Folds down for the ball to press the top part. Will be built into the roller's shock absorber, upper support and adjustable structure And with hydraulic hoses That separated freely Also connected to the control valve Hydraulic fold of the hydraulic cylinder 3. Rolling method of smooth rolled metal products As stated in Clause 2, there is a characteristic that by measuring the built-in hydraulic pressure of the hydraulic cylinder folded down. Or in the hydraulic hose that goes into the said cylinder And by using the measured value as the basis for the control of the upward force, the bending force acting on the chokes of the workpiece rollers is set to the specified value.
