Stainless steel precision casting is the process of casting liquid metal into a casting cavity that is suitable for the shape of the part. After it cools and solidifies, the method of obtaining the part or blank is called casting. Obtaining castings through casting methods is called castings.

Casting structure design: ensuring its working performance and mechanical performance requirements, considering the requirements of casting technology and alloy casting performance for casting structure, the rationality of casting structure design has a great impact on the quality, productivity, and cost of castings.

Main design issues and requirements

The design of the box body should first consider the arrangement of the internal components and their relationship with the external components of the box body. For example, the shape and size of the box body should be determined for a lathe according to two requirements of equal height. In addition, the following issues should also be considered:

⑴ Meet the requirements for strength and stiffness. Ensuring strength is an important issue for box components that are subjected to high stress; But for most enclosures, the main indicator for evaluating performance is stiffness, because the stiffness of the enclosure not only affects the normal operation of transmission parts, but also affects the working accuracy of the components. The selection of fast and easy automation for casting parts is included.

⑵ Heat dissipation performance and thermal deformation issues. Friction and heating of components inside the box cause changes in the viscosity of the lubricating oil, affecting its lubrication performance; The increase in temperature causes thermal deformation of the box, especially the uneven distribution of thermal deformation and thermal stress, which has a significant impact on the accuracy and strength of the box.

⑶ Reasonable structural design. The arrangement of support points, the arrangement of reinforcement, the position of openings, and the design of connection structures should all be conducive to improving the strength and stiffness of the box.

⑷ Good craftsmanship. Including the processability of rough manufacturing, mechanical processing and heat treatment, assembly adjustment, installation and fixation, lifting and transportation, maintenance and repair, and other aspects.

⑸ Good design and low quality.
