Abstract
The present invention relates to aluminium product technical field, especially aluminum product hot extrusions to form Frotteurism CAE analysis method；It includes design extrusion die, selects friction model, and technological parameter is arranged, and inputs physical function parameter；Influence of the different Frotteurisms to extrded material maximum temperature size is minimum, since the heat that contact friction generates can outwardly be scattered and disappeared completely by mold in forming process;Mold stress maximum value is both present at extrded material outflow lower die mold hole work belt under differentiated friction state, with the increase of friction factor, mold stress maximum value also increases with it, mold stress size can be reduced by improving extrusion die surface lubrication state, to achieve the purpose that reduce crack of die probability, improve mold Acceptable life, entreprise cost is reduced.
Description
Technical field
The present invention relates to aluminium product technical field, especially aluminum product hot extrusions to form Frotteurism CAE analysis method.
Background technique
Industrial aluminium hot extrusion technique and mold design are section quality and the important guarantee for improving die life, and are rubbed
The factor is to measure the important technical parameter of Frotteurism in hot extrusion process, to industrial aluminium product quality, Life of Die for Extruding Aluminium Alloy
It is all had a major impact with enterprises production efficiency.Currently, Experience Design extrusion die still leans on mostly in the industrial aluminium processing enterprise in China
Tool, so that the mold production cycle is longer, die trial causes cost too high repeatedly, and extrded material product quality is also difficult to ensure.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of analysis method, sets in industrial aluminium extrusion process and mold
CAE technology is used in meter, it can be with the mechanics such as extrded material shape and various places inside stress, strain in real-time simulation forming process
The distribution situation of field amount, helps to realize the time update and feedback of molding technique parameter and mold design.
The technical solution of the present invention is as follows:
Aluminum product hot extrusion forms Frotteurism CAE analysis method, it is characterised in that: it includes design extrusion die, selection friction
Technological parameter is arranged in model, inputs physical function parameter.
Specifically, carrying out CAE analysis in the design extrusion die to its hot extrusion molding process, calculating lower die die hole
Locate land length, while utilizing Pro/E software building profile extrusion die.
Specifically, using normal friction factor model in the selection friction model.
The invention has the benefit that influence of the different Frotteurisms to extrded material maximum temperature size is minimum, at
Since the heat that contact friction generates can outwardly be scattered and disappeared completely by mold during type;Under differentiated friction state mold by
Power maximum value is both present at extrded material outflow lower die mold hole work belt, and with the increase of friction factor, mold stress is maximum
Value also increases with it, and mold stress size can be reduced by improving extrusion die surface lubrication state, to reach reduction mould
The purpose for having cracking probability, improving mold Acceptable life reduces entreprise cost.
Specific embodiment
It is described further With reference to embodiment:
Aluminum product hot extrusion forms Frotteurism CAE analysis method, it includes design extrusion die, selects friction model, and work is arranged
Skill parameter inputs physical function parameter.
In the design extrusion die, CAE analysis is carried out to its hot extrusion molding process, calculates work belt at lower die die hole
Length, while utilizing Pro/E software building profile extrusion die.
Normal friction factor model is used in the selection friction model.
The above embodiments and description only illustrate the principle of the present invention and most preferred embodiment, is not departing from this
Under the premise of spirit and range, various changes and improvements may be made to the invention, these changes and improvements both fall within requirement and protect
In the scope of the invention of shield.
Claims (3)
1. aluminum product hot extrusion forms Frotteurism CAE analysis method, it is characterised in that: it includes design extrusion die, and selection rubs
