Embodiment

[0036] see Figure 1 to Figure 4 , in the present embodiment, the milling method of AF1410 steel large complex structural parts after quenching comprises the following steps,

[0037] 1. If Figure 4 As shown, design the special tooling 7 for milling. To prevent the part web 5 from vibrating during processing, the parts are pressed together by positioning the process lug 1 and the part web 5 at the same time, such as figure 1 shown.

[0038] 2. Choose a five-axis machine tool, and the five-axis machine tool should have a high-pressure cooling system. Parts and tooling 7 are placed on the machine tool.

[0039] 3. Since the hardness of the part material is above HRC50, in order to prevent the tool from chipping, or even the cutting edge falls off in a large area, choose the YW-type cemented carbide tool with HRC90-92.

[0040] 4. If figure 1 As shown, according to the characteristics of different regions of the part, different lengths of tools are selected for partition pro...

Abstract

The invention belongs to the technical field of mechanical processing, and particularly relates to a milling method of AF1410 steel large-sized complex structural parts after quenching. The milling method realizes the precision, high efficiency and low-cost processing of the AF1410 steel large-sized complex structural parts through a process method combining large cutting depth radial layering andsmall cutting depth axial layering. By means of the method, the service life of a cutter can reach 10-20 hours, and the wear and the machining cost of the cutter are greatly reduced; and meanwhile, the vibration of the cutter is effectively inhibited, the processing efficiency and the part quality are improved, and the precision and low loss milling machining of the material parts after quenchingstrengthening is realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a quenching and milling method for a large complex structural part of AF1410 steel. Background technique [0002] AF1410 steel, also known as 16Co14Ni10Cr2Mo steel, is affected by the internal structure change and part structure after quenching. Some large-scale, complex structure and strict assembly requirements of the finished parts of this material are different in three dimensions after quenching and strengthening. The degree of uncontrollable deformation causes the parts to fail to meet the requirements of the three-dimensional drawing. In order to solve this problem, the most direct and controllable way is to subvert the traditional process plan and implement the process strategy of quenching and strengthening before milling the parts. However, the hardness of AF1410 steel is greatly improved after quenching and strengthening, usually above HRC50,...
