Pressing machine, crank pressing machine, and vibration processing method in these machines

Abstract

A press, comprising: an electric motor (19) that rotates a crankshaft (13) to raise and lower a slider (11); input items include the height, position, and vibration of the slider (11) at the start and end of vibration processing; The motion data of the speed of the slider (11) during processing, the rotation angle of the crankshaft (13) in one direction during the pushing operation, and the rotation angle of the crankshaft (13) in the other direction during the return operation are input and operated by the operator. The motion data input unit (29) of input; Generate the motion pattern generating unit (63) of the motion pattern of slider (11) based on the motion data input to the motion data input unit (29); (63) the motor control unit (73) to control the electric motor (19) from the generated motion pattern.

Description

technical field [0001] The present invention relates to a press machine, a crank type press machine, and a vibratory machining method on the above-mentioned machine, which vibrate a workpiece through the cooperative action of a punch die and a die die while vibrating a slide block. Background technique [0002] There are various processing methods for press machines, and one of these processing methods is vibration processing in which a slider is vibrated to form a workpiece with a press load lower than usual. This vibratory processing is performed by, for example, alternately repeating a so-called push-in operation and a so-called return operation. Here, the so-called push-in action refers to the action of lowering the slider by rotating the crankshaft in one direction, and pushing the workpiece to the side of the female die with the punch die. Rotate to raise the slider and return the punch die upward. [0003] In addition to the servo motor that rotates the crankshaft t...

Problems solved by technology

Therefore, it takes time for the operator's input operation, and the operator's work becomes complicated

In particular, when the height position of the slider at the start of vibrating machining, which is one input item of motion data, is changed, the motion data must be greatly revised, and the work of the operator becomes more complicated.

[0008] In addition, the vibration process is performed on the workpiece by alternately repeating the push-in operation by the slider's descent and the return operation by the slider's ascent, so the machining time of the vibration process becomes longer.
