Abstract

The invention discloses a quick-change-type pulse current processing and laser shock foil composite microforming device capable of automatically centering and adjusting spot diameter and a method of the quick-change-type pulse current processing and laser shock foil composite microforming device, and relates to the technical field of advanced manufacturing micro-parts. The quick-change-type pulsecurrent processing and laser shock foil composite microforming device includes a laser emitting system, a space position adjustment system, a control system and a micro-part forming system. The methodcomprises the steps that first, a feature pattern set on a concave die is scanned by a three-dimensional camera, and the position of the feature pattern is compared with the position of a preset theoretical pattern to adjust the horizontal position of a three-dimensional mobile platform; then ultrasonic waves are emitted to an ultrasonic reflection platform and the total time of the whole processis calculated, the distance between the three-dimensional mobile platform and an adjustable-focus lens is calculated, then quick pressing of the device is realized by a magnetic suction device, and apulse current is applied to the two ends of foil; and finally, through pulse laser shock, impact force is generated by using explosion of plasma, and forming of the foil is realized, The accuracy ofa laser action point can be significantly improved, and the forming quality of the metal micro-parts is improved.

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 compound micro-forming device and method thereof that can automatically center and adjust the spot diameter. 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. However, since the distribution form of the laser impact force is Gaussian spatial distributio...

Problems solved by technology

However, this method only uses laser shock as a processing technology, and the pressing method is relatively complicated. It needs to rely on multiple bolts to connect and fix the clamping device. Therefore, the disassembly process after processing is relatively cumbersome, that is, two adjacent processing long cycle times
