Device for descaling by high-pressure water

Abstract

The invention discloses a device for descaling by high-pressure water, comprising a high-pressure water convey device, a shield, a left baffle closing device, a right baffle closing device, a charge-discharge roller way, a centring device, and an oxide scale collecting device, wherein the high-pressure water convey device is located at the left side of the shield; a trolley is located on a rail; a nozzle is installed at the outlet end of a high-pressure water tube; the shield is a cover body with respectively open left end, right end and bottom; the left and right baffle closing devices are located at the left and right ends of the shield respectively, for closing the openings at the left and right ends of the shield; the centring device is located in front of the shield; and the oxide scale collecting device is placed below the shield. The device for descaling by high-pressure water disclosed by the invention can efficiently remove the oxide scale on the inner surface of a tube blank, and increase the quality of the forged inner surface of the tube; the high labour intensity of manual descaling is avoided; the descaling working efficiency of the tube blank and the forging production efficiency of the tube are increased; the oxide scale removal effect is good; and the actual problems in a radial forging production are solved.

Description

technical field [0001] The invention belongs to the technical field of radial forging production, more specifically, the invention relates to a high-pressure water descaling equipment for the inner surface of a tube blank produced by radial forging. Background technique [0002] When producing pipes by radial forging, due to the requirements of the process, the oxide skin on the inner surface of the tube blank due to heating and oxidation must be removed first. Due to the high temperature required for forging the tube blank, there are many scales in the heated tube blank, which are difficult to remove. If the scale is not removed, it will have a serious impact on the quality of subsequent radial forging production. Domestic forging usually removes the oxide skin on the inner surface of the pipe manually, which is labor-intensive, low in efficiency, and poor in oxide skin removal effect. Contents of the invention [0003] The technical problem to be solved by the present i...

Problems solved by technology

Due to the high temperature required for forging tube blanks, there are many scales in the heated tube blanks, which are difficult to remove. If the scales are not removed, it will seriously affect the quality of subsequent radial forging production.

Domestic forging usually removes the scale on the inner surface of the pipe manually, which is labor-intensive, low in efficiency, and poor in scale removal effect.
