Description

Intelligent metal drawing device and method based on neural network
Technical Field
The invention relates to the technical field of metal material drawing forming, in particular to an intelligent metal drawing processing device and method based on a neural network.
Background
With the development of communication technology, various industries are based on a 5G road for large data and intelligent manufacturing, however, the development of the industries is not separated from materials, industries such as industry, agriculture, military industry, semiconductor, metallurgy, aerospace and the like are closely related to alloy materials, the industries have certain requirements on the hardness, strength and plastic toughness of the materials, however, an inverted relationship exists among the strength, the hardness and the plastic toughness of the materials, the strength and the hardness of the materials can not meet the toughness of the materials, and otherwise, the strength and the hardness of the materials can not be ensured. The processing of many cast strands of material after their exit is often an important part of the process.
As a new process capable of effectively improving the organization and performance of materials at high speed, the high-energy electric pulse technology focuses on the following three aspects:
1) the high-energy electric pulse treatment of solid metal can control the microstructure evolution and performance of material, including refining crystal grains, reducing segregation and changing microstructure morphology. In the metal rolling process, by applying a directional pulse current to two ends of a processed material, the deformation resistance of the material can be quickly and effectively reduced, and the plasticity of the material can be improved.
2) The high-energy electric pulse treatment is carried out on the liquid metal in the solidification process, when the metal material is in a solid-liquid two-phase region, the high-energy electric pulse treatment can obviously improve the cast structure of the material, can accelerate the formation of crystal nucleus, and simultaneously inhibits the growth of crystal grains to obtain uniform and refined crystal grains.
In the prior art, there are many processes for roll forming metal materials using high-energy electric pulse technology, but many of them exist only in laboratory test results. For example, the prior art discloses an electro-plastic rolling method and system for deformed magnesium alloy sheets, strips and wires, which lead in instantaneous high-energy pulse current during rolling to cause the phenomenon of plasticity increase in local processing areas. The process applies laboratory experimental results (such as rolling speed and deformation) to the magnesium alloy rolling process, wherein the rolling speed needs to be adjusted manually, and the instantaneous high-energy pulse current is introduced in each pass, so that the rotating speed, the rolling extrusion force, the traction force, the pulse current frequency, the current density, the pulse width and other parameters of a motor need to be readjusted. The prior art also discloses an electro-plastic strengthening and toughening treatment method and system for the AZ91 magnesium alloy strip with high strength and toughness, wherein the process is to rapidly induce the recrystallization phenomenon by utilizing the coupling effect of the thermal effect and the non-thermal effect of high-energy pulse current during the rolling of the AZ91 magnesium alloy. The process needs to replace the rolling mill after one-pass rolling, and relevant parameters are reset. The prior art discloses an ultrahigh frequency induction heating rolling technology for a deformed magnesium alloy wire, which comprises the steps of heating the magnesium alloy wire to 250-450 ℃, and then carrying out hot rolling processing.
The initial parameters of the process method are all test results obtained from a laboratory, and all the test results are set to a certain step length by a variable control method, so that the process method has certain limitations and cannot judge whether the process is the optimal process. Meanwhile, when the material is processed by the traditional processing technology and equipment, the problems of high labor cost, uneven structure, poor quality of rolled products and the like can occur.
