What is a casting

Casting of liquid metal casting to the shape of parts with the corresponding casting cavity, casting to be cooled to solidify, in order to obtain parts or rough method called casting. Casting method is called casting casting.

Casting structural design: to ensure its work performance and mechanical performance requirements, taking into account the casting process and alloy casting performance requirements on the casting structure, cast structure design is reasonable or not, casting quality, productivity and cost have a great impact.

Design of the main issues and design requirements

Box design must first consider the layout of the parts of the box and the external parts of the box, such as the lathe according to two top requirements to determine the box shape and size, in addition to the following issues should be considered:

⑴, to meet the strength and stiffness requirements. Satisfying strength is an important issue for box parts with large forces, but for most cases, the primary criterion for evaluating performance is stiffness, since the rigidity of the box affects not only the normal operation of the drive components, but also the Working precision. Casting pieces fast easy excellent automation selection has included.

⑵, structural design and reasonable. Such as the arrangement of the fulcrum, the arrangement of the ribs, the location of the openings and the design of the connecting structure, etc., are favorable for improving the strength and rigidity of the box.

Thermal performance and thermal deformation. Friction heating of the parts of the box makes the viscosity of the lubricating oil change, which affects its lubrication performance; The temperature rise causes the box body to have the heat distortion, especially the temperature distribution and the thermal deformation, the box precision and the strength are very big influences.

⑶, process is good. Including rough manufacturing, machining and heat treatment, assembly adjustment, installation of fixed, hoisting transport, maintenance, repair and other aspects of the process.

⑷, thermal performance and thermal deformation. Friction heating of the parts of the box makes the viscosity of the lubricating oil change, which affects its lubrication performance; The temperature rise causes the box body to have the heat distortion, especially the temperature distribution and the thermal deformation, the box precision and the strength are very big influences.

⑸, shape is good, small quality.
