Embodiment 1

[0025] Example 1. Processing methods to avoid micro-defects in the bottom of sealing grooves of aluminum alloy parts, such as Figure 1 to Figure 3 As shown, the method uses the plastic deformation of metal extrusion combined with the cutting characteristics of aluminum alloy to process the groove bottom of the sealing ring in an interactive way of cutting and smoothing and micro-extrusion to avoid the occurrence of micro-defects in the bottom of the sealing groove and achieve Processing requirements for sealing grooves.

[0026] The method is to process the sealing groove through three steps of rough machining, semi-finishing and finishing, the rough machining is used to remove most of the margin of the sealing groove, and provides a processing basis for semi-finishing and finishing; Semi-finishing is to process the sealing ring by using a higher tool speed and a lower feed rate than roughing to improve the surface quality and dimensional accuracy of the sealing ring groove;...

Embodiment 2

[0034] Example 2: image 3 It is a schematic diagram of the aluminum alloy shell of a certain product. In the figure, there is a sealing ring groove with a width of 4mm and a depth of 2.6mm. Conventional tools are used for rough machining, and the machining depth of the sealing groove is 2.4mm, and the machining depth for semi-finishing is 2.55mm. Finally, the cutting and extruding tool is used to finish the final finishing of the sealing groove by smoothing and micro-extruding, reaching the technical requirements of a depth of 2.6mm and a roughness of the groove bottom of the sealing ring of 1.6.

Abstract

The invention discloses a machining method for avoiding aluminum alloy component sealing groove bottom microdefects and a cutting tool. According to the method, metal extrusion plastic deformation iscombined with the aluminum alloy cutting character, a sealing ring groove bottom is machined in the manner of alternated conduction of cutting and the finishing micro extrusion action, occurrence of the sealing groove bottom microdefects is avoided, and the sealing groove machining requirement is met. The cutting tool adopted in the method comprises a positive rake angle cutting edge and a small negative rake angle cutting edge which are arranged in a spaced manner. According to the machining method, the machining precision is high in the aluminum alloy component machining process, the microdefects of the sealing groove bottom can be avoided, the mechanical manufacturing requirement is met, and the cost caused by scrapping of shells in the later machining period due to the microdefects isreduced.

Description

technical field [0001] The invention relates to a mechanical processing method and a cutting tool, which are a processing method and a cutting tool for avoiding micro-defects at the bottom of sealing grooves of aluminum alloy parts. Background technique [0002] In the processing and assembly process of mechanical products, it is often required to install rubber sealing rings in the sealing groove to seal the internal hydraulic pressure of the casting aluminum alloy shell parts. Due to the characteristics of the casting process, casting micro-defects are usually unavoidable and distributed irregularly. According to HB963 "Specification for Aluminum Alloy Castings", casting pinholes and looseness of aluminum alloy castings are allowed according to the level. However, for cast aluminum alloy shell parts of aircraft and engines, it is required that there are no defects in the sealing groove. For aluminum alloy casting characteristics, it is difficult to meet such zero-defect ...
