MOTOR DRIVE POWDER MOLDING MACHINE AND ITS CONTROL DEVICE

PROBLEM TO BE SOLVED: To provide a motor powder molding machine which can improve the followability of a drag at the acceleration/deceleration of a cope, and its control device.SOLUTION: In a control device 50 of this motor drive powder molding machine 1, the control device 50 controls moving speeds of a cope (UR) 30 and a drag (Ll) 20 of the motor drive powder molding machine 1 for performing proportional molding, and has drag target speed setting means for acquiring an actual speed of the cope (UR) 30, multiplying a prescribed speed ratio with the actual speed of the cope (UR) 30, and setting a target speed of the drag (Ll) 20. The drag target speed setting means performs at least either of correction for correcting a speed ratio to a large value compared with the case of constant speed movement at the acceleration of the cope (UR) 30, and correction for correcting the speed ratio to a small value compared with the case of the constant speed movement at the deceleration of the cope (UR) 30.SELECTED DRAWING: Figure 2 【課題】上型の加減速時に下型の追従性を向上させることができるモータ駆動粉末成形機及びその制御装置を提供する。【解決手段】実施形態に係るモータ駆動粉末成形機１の制御装置５０は、比例成形を行うモータ駆動粉末成形機１の上型（ＵＲ）３０及び下型（ＬＩ）２０の移動速度を制御する制御装置５０であって、上型（ＵＲ）３０の実速度を取得して、上型（ＵＲ）３０の実速度に所定の速度比を乗算して下型（ＬＩ）２０の目標速度を設定する下型目標速度設定手段を有し、下型目標速度設定手段は、上型（ＵＲ）３０の加速時には定速移動時に比べて速度比を大きな値に補正する、及び、上型（ＵＲ）３０の減速時には定速移動時に比べて速度比を小さな値に補正する、のうちの少なくとも一方の補正をする。【選択図】図２
