Description

technical field [0001] The invention belongs to the field of automation, and relates to a digital twin-based casting and forging dual-control forming system and a parameter optimization method. Background technique [0002] At present, a single casting or forging method is difficult to meet the production needs of some precision parts with complex shapes and high performance requirements. Casting and forging technology is mainly used in the production of non-ferrous metals with low melting points. For ferrous metals, the casting and forging equipment and technology are still immature, and there are still many areas that need to be improved. For example, the selection and control of forming process parameters is the key to realize the advantages of casting and forging dual control technology, which has a great impact on product performance, production cycle and manufacturing cost, but the traditional process parameter setting method relies on the experience of process personn...

Problems solved by technology

For example, the selection and control of forming process parameters is the key to realize the advantages of casting and forging dual control technology, which has a great impact on product performance, production cycle and manufacturing cost, but the traditional process parameter setting method relies on the experience of process personnel and based on The enumeration method of the test leads to high cost, low efficiency, long cycle and large blindness of parameter setting, which is often difficult to achieve in the face of a large number of process parameter combinations

At the same time, the casting and forging double-controlled forming process includes the flow of high-temperature metal solution, solidification and plastic deformation, which are complex with each other in material and heat transfer, deformation and phase transformation. There are many process parameters and the process parameters are related to each other. The relationship between process parameters and product quality is highly nonlinear, strongly coupled and time-varying, so it is extremely difficult to control process parameters
