High-pressure water-jet progressive forming is a new type of metal sheet forming technology. Its forming principle is to spray a water column with a certain jet pressure onto the metal sheet to cause local plastic deformation. Under the control of the computer, the high-pressure water column moves along a given path, and the parts are processed step by step until they are finally formed. High-pressure water jet progressive forming technology processing technology sheet has many advantages: 1. Realize the moldless forming of metal sheet, save the time of designing and manufacturing mold costs, very suitable for processing and prototype development of small batch products; 2.

When the sheet is formed, the contact surface is liquid-solid, no friction, no lubrication, and the pressure distribution on the contact surface is more uniform, so the surface quality of the part is better.

In high-pressure water jet incremental forming, initially, the high-pressure water column is perpendicular to the surface of the metal sheet. As the forming progresses, the angle between the high-pressure water column and the surface of the plate to be processed becomes smaller and smaller, especially when forming a large-angle side wall or straight wall workpiece, this phenomenon reduces the impact of the high-pressure water column on the workpiece. The size of the striking force affects the forming efficiency and accuracy, and even cannot be formed. In order to solve the problem, in the forming process, the water gun that sprays out the high-pressure water column is required to be able to tilt and rotate at a certain angle, so that the high-pressure water column jet that it sprays out is basically perpendicular to the surface of the workpiece, so that the jet energy can be fully utilized. The forming efficiency and precision are guaranteed.
