High-pressure water descaling device and method for forge piece

Abstract

The invention discloses a high-pressure water descaling device for a forge piece. The high-pressure water descaling device comprises a spraying assembly and a flexible detection assembly, the spraying assembly comprises a spraying box with the front side and the bottom open, and the spraying box is used for conducting high-pressure spraying operation on the forge piece entering the spraying box so as to conduct descaling. The flexible detection assembly is arranged on the front side of the spraying box and comprises two rigid parts which directly face each other and are vertically arranged, springs sleeve the two rigid parts, the upper portions of the springs protrude out of the top ends of the rigid parts by a certain length to form free parts, an area where the forge piece passes is formed between the free parts of the two springs, and the forge piece passes through the space between the free parts of the two springs and then enters the spraying box to be sprayed. The invention further discloses a descaling method. The high-pressure water descaling device and method for the forge piece solve the problem of removing an oxide skin on the surface of the forge piece, have the advantages of stability and high efficiency, and fill the equipment blank of the high-pressure water descaling device in the forging field.

Description

Technical field [0001] The present invention belongs to the field of forgings, and more particularly to a forgings of high pressure water density devices and methods. Background technique [0002] When the metal material is thermoplastic molding such as forging, it is often necessary to heat and insulate at 1100 to 1300 ° C. Under this heating conditions, the surface of the forgings form a layer of dense oxide (scales), if the mode forging is not cleared Pressed in forgings, there will be sparp and pits after the surface of the forgings, resulting in the final forgings fail to meet the accuracy, roughness, etc., while also increase the difficulty of subsequent machining; Inside the parts in the access, the forging will become a waste; the additional oxide is high hardness. It not only increases the consumption of deformation energy, but also accelerates the wear of forging and reducing the service life of forging. At present, the demand for the surface quality of the forgings is ...

Problems solved by technology

[0003] High-pressure water descaling technology is a widely used scale removal process. It has a good removal effect on ordinary carbon steel materials with relatively regular shapes (round bars and sheets). When descaling, usually round bars or sheets Fix it on the conveyor belt, and use the conveyor belt to transport the material to the descaling room for automatic descaling. This method can be carried out in batches and has a high degree of automation, but it is mainly for the stage of mass production after the forging is formed, and for the heating of the forging. There is no high-pressure water descaling device for forgings in the test stage before and after forming. If the traditional conveyor belt method is still used for high-pressure water descaling, one is because if the forging is large in size, the conveyor belt required is too large, and the other is large forgings. Generally, it will not be mass-produced, and there is no need for conveyor belt automation to achieve mass production. The third is that some special-shaped forgings are complex in shape and cannot be fixed with a conveyor belt. For forging, the transfer time should not be too long. If you use a conveyor belt, you need to use a gripping device such as a manipulator to put the forging on the conveyor belt, and then hold it for forging after descaling. This process takes too long, so it needs to be designed A high-pressure water descaling device and method before forging die forging, used to solve the problem of descaling the surface of forgings after heating and before forming, so as to improve the surface quality of forgings
