Description

Technical Field

[0001] The utility model relates to the technical field of water jet cutting processing, in particular to a workpiece positioning device for water jet cutting processing. Background Art

[0002] The basic principle of water jet cutting is to use the principle of liquid supercharging to convert the mechanical energy of the power source into pressure energy through a specific device (such as a supercharging port or a high-pressure pump). The water with huge pressure energy then converts the pressure energy into kinetic energy through a small hole nozzle, thereby forming a high-speed jet. Since the speed of the water flow is extremely fast, it has great kinetic energy and can penetrate many hard materials. It can be used to cut metal materials, non-metallic materials and composite materials. It is low in cost, simple to maintain the equipment, and does not require additional cutting tools or abrasives during the cutting process. When the workpiece is processed by water jet cutting, the workpiece needs to be positioned to ensure the stability of the workpiece during cutting. In the prior art, the workpiece is fixed by side clamping. Due to the influence of the clamping force, the cut waste is not easy to fall off, resulting in the cutting part being blocked, which will interfere with the subsequent cutting and lead to low efficiency. For this reason, this application proposes a workpiece positioning device for water jet cutting to solve the above problems. Utility Model Content
