Abstract

The invention discloses a micro deep drawing automation device and method of driving a flyer to load a sheet through pulse laser. The micro deep drawing automation device comprises a laser generating system, an automatic forming system and a control system, wherein a laser generating device is composed of a laser controller, a laser transmitter and an optical fiber, and the automatic forming system is composed of an end cover, a focusing lens cone, a machine body, a micro deep drawing work table, a three-dimensional movable clamp, a base, a magnetic field varying device, a rotating disc multi-station device, a restraint layer-flyer integrating sheet, a storage device of the restraint layer-flyer integrating sheet and a recovery device of the restraint layer-flyer integrating sheet. The micro deep drawing automation device utilizes the pulse laser as a power source, carries out conversion between light energy and mechanical energy through a restraint layer-flyer integrating sheet device, and automatically drives the flyer to load the sheet through the pulse laser. The automatic forming system is relatively independent, the machining accuracy is free of external disturbance, and personal errors are avoided. A laser optical path and the micro deep drawing work table are both contained inside the machine body, and the safety of experiment operation is improved.

Problems solved by technology

However, the current device using laser-driven flyer micro-forming technology cannot continuously pulse laser-driven flyer micro-forming, and its mass production is only the forming of multiple dies under one pulse impact, which is not a rapid and continuous mass production in the true sense. Production, and because the workpiece and fixtures need to be re-clamped after a laser shock forming in this device and method, it is bound to bring human errors due to manual operations and affect the processing accuracy

Moreover, the open laser light path also has certain potential safety hazards
