Metal casting machining and manufacturing process

Abstract

The invention relates to a metal casting machining and manufacturing process. The process mainly comprises the following steps of raw material preparation, molding sand molding, material smelting, pouring operation, shakeout treatment, polishing operation and the like; and used casting polishing equipment comprises a bottom plate, a rotating device, a clamping device and a polishing device. The process can solve the following problems existing in existing casting grinding that a, existing casting grinding is mainly operated manually, a casting is placed on a platform in the grinding process, then a riser is aligned with a grinding wheel to be ground, the grinding depth is judged manually in the grinding mode, the grinding feeding amount is difficult to control, and the grinding quality isdifficult to guarantee; and b, a traditional casting grinding device is large in noise, severe in vibration, unstable in operation, inconvenient to adjust and operate, low in grinding efficiency, poorin grinding quality and prone to the phenomenon of incomplete grinding in the operation process; and the spraying efficiency of casting grinding can be improved.

Description

technical field [0001] The invention relates to the technical field of casting processing and manufacturing, in particular to a metal casting processing and manufacturing process. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, including steel castings, iron castings, copper castings, aluminum castings, etc. Castings are smelted liquid metals that are cast, injected, inhaled or otherwise cast The method is injected into the pre-prepared mold, and after cooling and grinding, the obtained object has a certain shape, size and performance. The casting has a wide range of uses and has been applied to hardware and the entire mechanical and electronic industries. After the casting is smelted and formed, burrs and particles often appear on the surface, which is not only unsightly, but also affects its quality in use, and the casting blank needs to be polished. [0003] However, the following problems exist in the grinding of exis...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the grinding of existing castings. a. The grinding of existing castings is mainly manual operation. It is difficult to control the grinding feed rate by manually judging the grinding depth. The environment of the grinding site is harsh, which affects the health of the grinder and is dangerous. Work-related accidents occur frequently. It is difficult to guarantee; b, the traditional casting grinding equipment has a lot of noise, strong vibration, unstable operation, inconvenient adjustment and inconvenient operation during operation, which makes the grinding efficiency low, the grinding quality is poor, and it is prone to incomplete grinding The phenomenon can improve the spraying efficiency of casting grinding
