Water-jet cutting machine

Abstract

The invention relates to a waterjet cutter which is characterized in that the waterjet cutter comprises a front and back moving frame with a vertical guide rail, a left and right moving frame which is connected with the vertical guide rail and is provided with a transverse guide rail, a waterjet cutting head which is arranged on the transverse guide rail in a left and right moving way and a workpiece bearing platform which is arranged under the waterjet cutting head. A support base comprises an inner support base and an external support base. Two ends of the inner support base are wrapping edges for wrapping the back front end and the bottom front end of the left and right moving frame. The external support base comprises a sloping plate and a turned-over edge which is arranged on the two ends of the sloping plate and turns inwards along the wrapping edges on the two ends of the inner support base. A protective cover plate is arranged between the inner support base and the external support base. The protective cover plate comprises a sloping cover plate, a turned-over edge angle plate which is arranged on the upper end of the sloping cover plate and a turned-over edge flat slab which is arranged on the lower end of the sloping cover plate. Compared with the prior art, the waterjet cutter has the advantages that back-washing water and sands during the workpiece processing can be prevented from polluting the guide rails, the swing amplitude of a waterjet cutting spray-head is small so that the mechanical processed workpiece precision cannot be influenced.

Description

Technical field: [0001] The invention relates to a stone or ceramic tile processing device. Background technique: [0002] Existing water jet cutting machines are generally composed of a front and rear moving frame with a vertical ball guide rail, a left and right moving frame with a horizontal ball guide rail connected to the vertical ball guide rail, and a left and right movement set on the horizontal ball guide rail. The waterjet cutting head is composed of a workpiece carrier set under the waterjet cutting head. In order to prevent the horizontal ball guide rail on the left and right moving frame above the workpiece carrier from being polluted by splashed water and sand during workpiece processing, the water The horizontal ball guide rail connected to the knife cutting head is set on the top of the left and right moving frame. Although such a setting can effectively prevent the horizontal ball guide rail on the left and right moving frame located above the workpiece carr...

[0002] Existing water jet cutting machines are generally composed of a front and rear moving frame with a vertical ball guide rail, a left and right moving frame with a horizontal ball guide rail connected to the vertical ball guide rail, and a left and right movement set on the horizontal ball guide rail. The waterjet cutting head is composed of a workpiece carrier set under the waterjet cutting head. In order to prevent the horizontal ball guide rail on the left and right moving frame above the workpiece carrier from being polluted by splashed water and sand during workpiece processing, the water The horizontal ball guide rail connected to the knife cutting head is set on the top of the left and right moving frame. Although such a setting can effectively prevent the horizontal ball guide rail on the left and right moving frame located above the workpiece carrier from being affected by the back splash when the workpiece is processed Water and sand pollution, however, prolongs the distance from the support point connecting the waterjet cutting head and the horizontal ball guide to the nozzle of the waterjet cutting head. Under the action of external force and its own mechanical vibration force, the nozzle moves along the support point The amplitude of the swing is increased, which seriously affects the accuracy of the workpiece processed by the machine
