Strength Analysis Method of Mosaic Forging Die Based on Uneven Temperature and Stress Distribution

Abstract

The invention discloses a method for analyzing the strength of an inlaid forging die based on uneven temperature and stress distribution. The specific steps are as follows: 1) Preliminary analysis of the forming process of the forging in DEFORM, according to the stress and temperature distribution of different parts of the die, in UG Divide the forging die into several pieces and assemble an inlaid mould; 2) Perform the forming analysis of the forging in DEFORM to obtain the stress and temperature distribution of different inserts; 3) Establish the mechanical analysis in ANSYS WORKBENCH, and complete the DEFORM direction through the interface ANSYS WORKBENCH data transfer to realize stress and temperature mapping of different inserts; 4) Based on the above uneven temperature and stress distribution mapping results, set the contact and heat transfer relationship between different inserts, and run mechanical analysis and calculation; 5) According to mechanical and temperature analysis As a result, the way of dividing the inserts can be further optimized, jump to 2). The invention solves the problem that the inhomogeneous distribution of temperature and stress cannot be considered in the analysis of the current mosaic type hot forging die, which leads to the distortion of the mechanical boundary conditions of the die and the unreliable simulation results.

Description

technical field [0001] The invention relates to the technical field of metal hot forging, in particular to a method for analyzing the strength of an inlaid forging die based on uneven temperature and stress distribution. Background technique [0002] Hot die forging has the advantages of high forming precision and stable forging quality. When using an integral hot forging die, due to the uneven temperature and stress distribution and the harsh service conditions of the die, the die is prone to local collapse and cracking defects, and the overall repair cost is extremely high. . The mould-inlay can solve this problem very well: according to the temperature and stress of different parts of the mold, different materials are used for different inserts, which solves the strength problem of the mold on the one hand, and greatly reduces the cost of mold manufacturing and production costs. maintenance costs. The mosaic mold also has the advantages of high manufacturing precision, ...
