Die-casting aluminum alloy, aluminum alloy die casting and manufacturing method of aluminum alloy die casting

Abstract

The invention provides a die-casting aluminum alloy, an aluminum alloy die-casting part and a manufacturing method of the aluminum alloy die-casting part, relates to the technical field of aluminum alloy machining, and solves the problems that part structures have defects, and connection between shafts and connection between shafts and pipes cannot be achieved through structural improvement. The problems that defects exist in the machining sequence, and abrasion of a cutter cannot be reduced and the machining time cannot be shortened by integrating the machining sequence are solved. The invention discloses a die-casting aluminum alloy, an aluminum alloy die-casting piece and a manufacturing method of the aluminum alloy die-casting piece. The part body is of a step-shaped structure, and the part body is formed in a die-casting mode. Through the arrangement of the groove A, when the interior of the groove A is in contact with the outer wall of the shaft, auxiliary fixing of the shaft can be achieved, and therefore the connecting strength is improved; through planning of machining steps, the groove A is machined at first, then the threaded hole and the through hole are machined after the groove A is machined, at the moment, drilling of a part of aluminum alloy materials can be reduced, and therefore the machining cost and tool abrasion can be reduced.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy processing, and more particularly, particularly relates to a die-casting aluminum alloy, an aluminum alloy die-casting part and a manufacturing method thereof. Background technique [0002] When the shaft and the tube are connected and connected, a connecting device needs to be used. This connecting device mainly realizes two functions: one is connection and the other is transmission. [0003] For example, application number: CN202010697127.9, the present invention discloses a die-casting aluminum alloy, an aluminum alloy die-casting part and a manufacturing method thereof. The die-casting aluminum alloy comprises 9.5 to 12 mass % of Si, 0.3 to 1.0 mass % of Si Fe, 0.15 to 0.35 mass % of Mg, and the balance of AI and inevitable impurities. The die-casting aluminum alloy of the invention has excellent thermal conductivity and castability, and is suitable for manufacturing aluminum alloy die...
