Mold movement and freedom of forging equipment is inconsistent ring gear, deformation characteristics of the ring parameters within the limits lower dead point, forging equipment can be divided into the following four forms: 1, limiting forging force forms: direct drive hydraulic slide block hydraulic machine. 2, quasi-stroke limit means: hydraulic drive crank linkage of hydraulic machine. 3, stroke limit means: crank, connecting rod and slide mechanism drives the wedge mechanical presses. 4, energy restriction mode: use screw press and friction screw mechanism. Heavy aviation hydraulic forging heat test in order to obtain high accuracy should be taken to prevent overloading the lower dead point, control the speed and position of the mold. Since these will be on forging tolerances, shape accuracy and die life affected. Another ring gear production, in order to maintain accuracy, attention should also adjust the slider guide clearance to ensure rigidity, adjust the lower dead point and use measures such as subsidies gear. Luoyang Super League forging Forging Co., tells you the level of analysis: Chinese forging industry in the introduction, digestion and absorption of foreign technology developed on the basis on the inside after years of technological development and transformation ring bracket, the industry leader in technology level, including process design, forging technology, heat treatment technology, machining technology, product testing and other aspects have been improved greatly. (1) process design of advanced thermal processing commonly used by manufacturers of computer simulation technology, computer-aided process design and virtual technology to improve the process design and product manufacturing capabilities. Introduction and application DATAFOR, GEMARC / AUTOFORGE, DEFORM, LARSTRAN / SHAPE and THERMOCAL and other simulation programs, computer design and implementation process of thermal processing control.
