摘要： A die cushion controller uses position control to position die cushion members for placement of a metal sheet. A pressing process starts and the upper die is lowered. When a position detector detects a position at which the upper die touches the sheet metal, the die cushion controller switches over from position control to pressure control and applies a preset pressure to the sheet metal. When the position detector detects that the upper die has risen to a preset position, the die cushion controller clears the positional deviation accumulated in position control to zero, then moves the die cushion members to preset positions and holds them there.

摘要： Die cushion control device that implements die cushion control while making a switch between position control and pressure control by using servomotors, and reduces the impact caused by a collision between a press axis and a die cushion axis during position control. Die cushion members are controlled by servomotors Md. The changeover switch is connected to the “a”-side, to thereby control the position (velocity) of the servomotors Md by commands from a numerical controller and control the position of the die cushion members. During position control, the output torque of the servomotors Md is limited by torque limit means. During position control, even if the press axis hits the die cushion members due to erroneous setting, wrong operation or the like, the servomotors Md merely output only a limited torque or less, so that impact force is reduced, which prevents damage to the die cushion members and the press axis. During press operation, when a position detector detects that the press axis moves downward to reach a predetermined position, the changeover switch is connected to the “b”-side, to thereby implement pressure control.
摘要翻译：模具缓冲控制装置，通过使用伺服电动机进行位置控制和压力控制之间的切换，实现模具缓冲控制，并且减少在位置控制期间由冲压轴和模具缓冲轴之间的碰撞引起的冲击。模具缓冲构件由伺服电机Md控制，转换开关连接到“a”侧，从而通过来自数字控制器的命令来控制伺服电机Md的位置（速度），并控制模具缓冲构件的位置。在位置控制期间，伺服电动机Md的输出转矩由转矩限制装置限制。在位置控制期间，即使由于错误的设定，错误的操作等而使按压轴碰到模具缓冲部件，伺服电动机Md只输出有限的转矩或更小的扭矩，从而减小冲击力，从而防止对模具的损坏缓冲构件和压轴。在按压操作期间，当位置检测器检测到按压轴向下移动到达预定位置时，转换开关连接到“b”侧，从而实现压力控制。

摘要： An ‘interval’ in which the synchronization status between the movable axes subject to synchronous control is monitored, an equation between the movable axes in the ‘interval’, and an ‘allowable displacement’ for the positional relationship obtained with this equation and the actual positional relationship are set in advance. The ‘start condition’ and ‘termination condition’ for synchronous status verification processing are set with the master position and the like. When the start condition for synchronous status verification processing is satisfied, it is detected whether or not the actual position and the position obtained with the equation are within the range of the allowable displacement based on the position of the movable axes. If not within the range of the allowable displacement, operation set as ‘operation to be executed when the allowable displacement is exceeded’ is executed.

摘要： A servomotor in a numerical controller is controlled by automatically switching to either pressure control or position control in association with the command which is smaller from among a command obtained by performing pressure feedback control and a command obtained by performing position feedback control. When switched to pressure control while moving according to a movement command, the output of the movement command is terminated halfway, and the command in the next block is executed, and pressure control of the next command is immediately started. As a result, a wasteful time is eliminated, and a cycle time of the operation can be shortened

摘要： The numerical controller has function to switch between pressure control and position control, and comprises a numerical control unit and a servo control unit. While the servo control unit is controlling pressure, a servo position deviation amount corresponding to current actual speed of a control axis is set in the servo control unit. After the servo control unit switches to position control from pressure control, a number of pulses required for deceleration and stopping is output to an acceleration/deceleration processing unit of the numerical control unit according to an acceleration/deceleration time constant which is preset. The acceleration/deceleration processing unit outputs a moving amount for each distribution period to the servo control unit.
