Embodiment Construction

[0023] The following description sufficiently illustrates specific embodiments of the invention to enable those skilled in the art to practice them.

[0024] like figure 1 Shown, is the front view of armor plate among the present invention; As figure 2 Shown, is the top view of armor plate among the present invention; As image 3 Shown is a schematic diagram of the structure of the armor plate fixed into a frame structure.

[0025] Due to the large length of the armor plate 1, distortion will occur during the quenching process, and this distortion is difficult to correct. In the present invention, after a single large armor plate 1 is formed, two armor plates 1 are welded together to form a single frame structure, which increases the rigidity of the parts, and increases the deformation direction when the frame structure is quenched. Constraints to control the deformation of the part. After a period of natural aging after the heat treatment of the frame structure, the over...

Abstract

The invention discloses a method for controlling the quenching deformation of a bending forming part of a large-scale armor plate. The method comprises the steps of connecting two formed armor platesthrough a tie bar, and welding to form a framework structure member; putting the framework structure member into a heating furnace, and carrying out heat treatment. The method provided by the invention effectively solves the technical problem that the large-scale armor plate is deformed during a quenching process so as to be incapable of being corrected.

Description

technical field [0001] The invention relates to an anti-deformation method for a large armor plate, in particular to a method for controlling the quenching deformation of a large armor plate bent formed part. Background technique [0002] At present, in the domestic manufacturing industry, there are often relatively large curved formed parts that require quenching heat treatment. The shape of the parts is relatively large in length and width, and there are arc formed parts with a certain angle in the length direction. Due to the high hardness required after the parts are formed, it is often in the range of 360-410HB. [0003] The main defect after heat treatment is twisting and deformation. Generally, the deformation is more than 7mm. The deformed parts cannot be corrected due to high hardness and high elasticity. After quenching, the angular size of the parts cannot be guaranteed. Now, the quenching of small shaped armor parts is carried out by pressure quenching on the qu...
