Embodiment 1

[0016] A method for mechanical processing of zinc castings, comprising the steps of:

[0017] (1) First heat the zinc casting to 650-700°C and maintain it for 15-25 minutes;

[0018] (2) Rapidly cool down the temperature of the zinc casting to 300-350°C within half a minute, and maintain it in the temperature range of 400-450°C for 10-15 minutes;

[0019] (3) After the zinc casting is heated rapidly to 500-600°C within half a minute, mechanical processing is carried out within the temperature range of 500-600°C.

Abstract

The invention provides a method for mechanical processing of zinc castings, which relates to the technical field of mechanical processing, comprising the following steps: (1) heating the zinc castings to 650-700°C and maintaining them for 15-25 minutes; The temperature of the zinc casting is rapidly cooled to 300-350°C within half a minute, and maintained in the temperature range of 400-450°C for 10-15 minutes; (3) The zinc casting is then rapidly heated to 500-600°C within half a minute After that, machining is carried out in the temperature range of 500‑600 °C. In the present invention, the present invention completely releases the stress inside the casting through rapid cooling and heating of the zinc casting, which can effectively prevent the casting from breaking during processing; at the same time, the mechanical processing is carried out at a temperature of 500-600°C, because the casting as a whole is in the In the high heat state and the hardness of the zinc casting is greatly reduced, the heat generated locally during machining is negligible and will not cause deformation damage to the casting.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a mechanical processing method of a zinc casting. Background technique [0002] Zinc casting is a general term for alloys mainly composed of iron, carbon and silicon. In these alloys, the carbon content exceeds the amount that can be retained in austenitic solid solution at the eutectic temperature. [0003] In order to apply zinc castings to mechanical parts, it is also necessary to machine the zinc castings. The existing machining methods for zinc castings have the following technical problems: [0004] 1. It is carried out at room temperature. Due to the generation of local heat during processing, the zinc castings will be deformed to a certain extent when processing the zinc castings; [0005] 2. The internal stress release of the casting is not complete, the generated torsion force is large, and it is easy to break during the processing. For example, the ordi...
