Problems solved by technology

However, when this process cuts a laminated structure such as a resin-based composite laminate, if there is no pre-made hole on the workpiece to be processed, when the water flow penetrates the workpiece for processing, the water flow will be blocked and spread around. Ultra-high pressure water flow It will penetrate between the layers of the laminate along the direction of the laminate, causing delamination or burrs on the laminate

Abstract

The invention relates to the technical field of machining, and discloses a high pressure water cutting device. The high pressure water cutting device comprises a machine tool and a cutting head. The cutting head is fixedly installed on the machine tool; the high pressure water cutting device further comprises a pneumatic punching device, the pneumatic punching device comprises a switching component, a lifting component and a pneumatic punching component, and the switching component is fixedly installed on the machine tool; the pneumatic punching component is vertically movably arranged on themachine tool and connected with a gas source; the lifting component is fixedly installed on the machine tool and used for driving the pneumatic punching component to move up and down. The high pressure water cutting device can perform pre-punching on a part to be machined, and then, cutting is performed, so that damage to parts in the cutting process is reduced, the structure is simple, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a high-pressure water cutting device. Background technique [0002] High-pressure water cutting is a method of cutting materials using high-pressure water flow. It has the advantages of fast cutting speed, smooth incision, no dust, no thermal deformation, and less material waste. Changes will occur, so high-pressure water cutting is gradually applied to the trimming and hole making of aerospace structural parts. However, when this process cuts a laminated structure such as a resin-based composite laminate, if there is no pre-made hole on the workpiece to be processed, when the water flow penetrates the workpiece for processing, the water flow will be blocked and spread around. Ultra-high pressure water flow It will penetrate between the layers of the laminate along the direction of the laminate, causing delamination or burrs on the laminate. Contents of the inven...
