Problems solved by technology

However, this method can only adjust the size of the laser spot acting on the workpiece, but cannot change the shape of the laser spot. This method is difficult for some complex microbending parts to be impact formed.
However, the laser shock bending forming technology still has defects such as low forming controllability and low workpiece clamping accuracy.

According to the device, accurate clamping of workpieces is achieved through the workpiece clamping device, the laser incremental shock forming accuracy is guaranteed, and masks in different shapes are used for changing the shapes of laser spots so as to adapt to workpiece shock incremental forming of any shape or requirement. The device is high in accuracy and automation degree and wide in application range, and accurate shock forming of the multiple workpieces can be achieved.

Description

technical field [0001] The invention relates to the field of laser shock forming, in particular to a device and method for progressive bending of metal foil plates based on laser shock. Background technique [0002] The forming technology of sheet metal has always occupied a very important position in the manufacturing industry. The traditional sheet metal forming technology utilizes the characteristics of metal plastic forming to achieve the purpose of deformation by applying pressure to the sheet metal. Under the action, it is realized by means of molds. The design of the mold is complex, the manufacturing cycle is long, the dependence between the molds is large, and the cost is high. It is difficult for the traditional forming method to meet the current market demand for single-room small batches and multiple varieties. In this context, a new moldless technology - laser shock forming has received widespread attention. Laser shock forming is a new moldless technology that...
