Intelligent plastic forming process method and intelligent plastic forming equipment used for same

Abstract

The invention discloses an intelligent plastic forming process method and intelligent plastic forming equipment used for the same. The process method sequentially comprises the steps that three-dimensional modeling and plastic deformation digital simulation are conducted, an automatic programming system with a machine learning function is adopted for completing analysis and programming of the forming step of a forge piece, a steel ingot is heated, closed-die upsetting is conducted on the steel ingot, and plastic forging forming is conducted by squeezing a blank on an intelligent plastic forming hydraulic machine through rolling tools. According to the equipment, intelligent manipulators installed on the intelligent plastic forming hydraulic machine drive intelligent pressing heads to rotate around the axes in the horizontal direction or the vertical direction, and wedging angles larger than zero degree are formed by the squeezing surfaces of the rolling tools on the intelligent pressing heads and the surface of the forge piece; a supporting device can drive the forge piece to rotate and move; a sensing system can obtain data of the temperature of the forge piece, the pressure of the rolling tools on the forge piece and the forge piece metal flowing displacement and send the data to a control system; the control system controls actions of all components. According to the intelligent plastic forming process method and the intelligent plastic forming equipment used for the same, the forging precision is high, materials are saved, no special molds are needed, the forging flexibility is high, and the cost is low.

Description

technical field [0001] The invention relates to a metal forming process and its used forming equipment, in particular to an intelligent plastic forming process and its used intelligent plastic forming equipment. Background technique [0002] Any large-scale energy conversion requires high reliability, large and super-large pressure vessels, such as nuclear power and thermal power; super-large pressure vessels in marine oil and gas storage and transportation systems; titanium alloy pressure shells for missiles and rockets; submarine hyperbaric chambers Walls, torpedo tubes and various missile launching devices, as well as large, medium and small natural gas cylinders, etc. are all important pressure shell shell parts, too numerous to mention. Shell (or pressure shell) refers to a large-scale forged structural member with a wall thickness-to-radius ratio of less than 10%, non-casting, welding-limited (a small number of welds allowed) that withstand internal and external pressu...

AI Technical Summary

Problems solved by technology

[0005] It can be seen that the traditional heavy-duty free forging is difficult to form and manufacture large and super-large shells due to insufficient precision, serious material waste, long manufacturing cycle, and low product rate; g
