by the feed-back control of the duty ratio according to the oscillations of the movable plate, the movable plate can be controlled to oscillate in the proper phase and at the proper oscillation angle.
通过根据可移动板的振动对占空比的反馈控制,可控制可移动板以在适当的相位和适当的振动角振动。
provided is an oscillating device, which can adjust the oscillation angle and the phase of a movable plate easily with a simple constitution.
提供一种振动设备,其可通过简单的构成轻易地调节可移动板振动角和相 位。
by controlling the wedge block and springs, its punches and movable plate blocks achieve the horizontal punch movement.
该模具的凸模和活动凹模镶块分别在斜楔和楔形滑块作用下水平相向运动完成沖裁。
as the angle grinder adopts the machine shell equipped with the transparent detection hole, the movable plate can be disassembled for direct adjustment installation after a motor is damaged.
