Rolling apparatus

Abstract

The rolling apparatus is configured to execute a control content for producing a test piece by forming fixed-side streaks and moving-side streaks in a base material, and a control content for receiving an inputted positional deviation amount between groove center lines of the moving-side streaks and virtual groove center lines of the fixed-side streaks, and then for calculating and outputting a correction movement amount, based on the positional deviation amount, for use in correcting and adjusting the moving flat die at a top dead center thereof. Further, the rolling apparatus is configured to execute a control content for receiving and outputting an input of bite depths of the fixed-side streaks and moving-side streaks in the test piece.

1 . A rolling apparatus including
 a fixed flat die fixed on a base table and having a fixed-side rolling-surface section, and   a moving flat die disposed reciprocally movable along a rolling direction on the base table, the moving flat die having a moving-side rolling-surface section opposite, during rolling processing, to the fixed-side rolling-surface section,   
       the rolling apparatus comprising:
 a top-dead-center position adjusting means configured to adjust a position of a top dead center of the moving flat die along the rolling direction by manual manipulation; 
 a test-movement control means configured to execute a control content for producing a test piece having both a fixed-side streak in a groove shape based on the fixed-side rolling-surface section and a moving-side streak in a groove shape based on the moving-side rolling-surface section, the fixed-side streak and the moving-side streak being formed in a base material to be the test piece by automatically controlling both a going movement of the moving flat die that moves from the position of the top dead center along the rolling direction by a predetermined movement amount so as to cause the base material to rotate a half turn and a return movement of the moving flat die that returns to the position of the top dead center; 
 a positional-deviation-amount inputting means configured to receive an inputted positional deviation amount of the moving-side streak with respect to an appropriate position of the moving-side streak in a direction along an axis of the test piece, the appropriate position being determined, in a front elevation view of the test piece, to be a position of the moving-side streak in a state in which a center line of the groove of the moving-side streak coincides with a virtual groove center line defined by extending a center line of the groove of the fixed-side streak; and 
 a correction-movement-amount calculation controlling means configured to execute a control content for calculating a distance of the moving flat die to an appropriate position of the top dead center as a correction movement amount of the moving flat die based on the inputted positional deviation amount; 
 
       in the rolling apparatus, at least one of the fixed flat die and the moving flat die being disposed and capable of being positionally converted along an opposing direction in which the fixed-side rolling-surface section is opposed to the moving-side rolling-surface section, 
       the rolling apparatus further comprising:
 an opposing-position adjusting means configured to adjust, by manual manipulation, a relative position between the fixed flat die and the moving flat die in the opposing direction; 
 an opposing-position detecting means configured to detect the relative position between the fixed flat die and the moving flat die in the opposing direction; 
 a bite inputting means configured to receive an inputted bite depth, in a radial direction of the test piece, of the fixed-side streak and the moving-side streak formed by the test-movement control means; and 
 an adjustment-value outputting means configured to output the correction movement amount calculated by the correction-movement-amount calculation controlling means, opposing position information based on the relative position, in the opposing direction, detected by the opposing-position detecting means, and the inputted bite depth received by the bite inputting means. 
 
     
     
         2 . The rolling apparatus of  claim 1 , wherein the adjustment-value outputting means is configured to execute
 a control content for displaying the inputted bite depth received by the bite inputting means on a predetermined display section, and   a control content for sequentially displaying the opposing position information on the display section in accordance with position adjustment of the relative position in the opposing direction by the opposing-position adjusting means.   
     
     
         3 . The rolling apparatus of  claim 1 ,
 wherein the adjustment-value outputting means is configured to display a movement-amount corresponding graphic part on a predetermined display section, and   wherein the correction-movement-amount calculation controlling means is configured to execute
 a control content for producing the movement-amount corresponding graphic part in accordance with the movement amount in directions each orthogonal to the rolling direction of the moving flat die and the opposing direction in which the fixed-side rolling-surface section is opposed to the moving-side rolling-surface section, and 
 a control content for causing the adjustment-value outputting means to display the produced movement-amount corresponding graphic part.
