The device includes a laser emitting system, a control system and micro part forming system; the laser emission system is used to generate laser light, and the control system is used to control the work of the forming device; the micro-forming system is used for workpiece forming; the micro-part forming system includes a pressing plate, a cavity and a supporting platform; The magnetic suction device is used to realize the rapid compression of the device, and then the metal foil is punched through the cylinder, and then the pulse laser is used as the energy source, and the plasma explosion is used to generate the impact force, so as to realize the forming of the foil, and finally the part is punched through the cylinder. The ejection and cylinder reset and the rolling material of the coil device realize the rapid replacement of workpieces, and at the same time, the die replacement device can be used to realize the rapid replacement of dies; the invention can complete the forming of metal micro parts at one station.

Description

technical field [0001] The invention relates to the technical field of advanced manufacturing micro-parts, in particular to a quick-change pulse current processing and laser shock foil composite replaceable die micro-forming device and method thereof. Background technique [0002] With the rapid development of today's productivity, especially in the field of aerospace and automobile manufacturing, the requirements for the strength and manufacturing accuracy of micro-parts with micro-features are also getting higher and higher, so a high-precision, high-quality micro-forming Process to ensure the precision of workpiece forming. Laser shock microforming is a processing method that uses laser energy as the shock source to instantly cause plastic deformation of the workpiece, which can form micro parts with better quality and higher precision. [0003] Relevant studies have shown that electroplastic effects can be produced on metal materials by applying pulse currents to them. ...

AI Technical Summary

Problems solved by technology

However, this method only uses laser shock as a processing technology. Due to the limitation of the structure of the device itself, it is impossible to efficiently replace the die, and the pressing method is relatively complicated, and it needs to rely on multiple bolts to connect and fix the clamping device. , so the disassembly process after the processing is completed is relatively cumbersome, that is, the interval between two adjacent processing cycles is relatively long
