Abstract
The invention provides a hot bending molding temperature indication paste for an aluminum alloy tubular product and a bending molding method. The temperature indication paste is formed by adopting daily soap, beef tallow, vegetable oil and water through smelting and solidifying, and the temperature indication paste is changed in color when being heated to a certain temperature interval. According to the hot bending molding temperature indication paste for an aluminum alloy tubular product and the bending method using such indication paste, by coating the front surface to be bent of the aluminum alloy tubular product with the temperature indication paste, an alcohol blast burner is used for heating the coated region to be bent with flame in a bending process, a proper heating temperature interval is confirmed according to color change of the temperature indication paste, then bending molding is performed to realize hot bending molding of an aluminum alloy pipeline, a cracking risk of the tubular product caused by overlow or overhigh heating temperature is avoided, operation is simple and practicability is high.
Description
Technical field
The present invention relates to tube plastic forming field is and in particular to aluminium alloy pipe hot bending forming temperature indicator paste and use
The bending method of this temperature indicator paste.
Background technology
Tube bending forming is to be bent into tubing blank to have moulding of certain bending radius, certain angle of bend and shape
The property course of processing.With the development of computer technology and Numeric Control Technology, the bending forming realizing tubing using Numeric Control Technology is progressively
Substitute manual bend pipe.
In recent years, the bent pipe parts in the field such as space flight, space flight are using more and more extensive, the especially fortune of aluminium alloy pipe
With.Due to the structure design characteristic of space product itself, bending radius too small extremely indivedual tubing occur in production, this cannot
Using conventional numerical controlled bending of pipe equipment, and generally shape to process using artificial hot bending, that is, utilize alcohol blast burner to be curved to tubing
Pars convoluta position moves regionality and is heated to certain temperature, by manually bending, makes forming tubular product.Because heated perimeter is
Regionality, simultaneously flame for the moment mobile it is impossible to be characterized with infrared measurement of temperature one-point measurement data, suitable in bending forming process
Run jointly exhibition aluminium alloy pipe bending forming temperature range be difficult to directly perceived, simple control, usually occur heating-up temperature too low or
Too high, the problems such as causing bending pipes cracking or cannot shape.
In sum, a kind of side directly perceived, simply distinguishing the temperature range that suitable aluminium alloy pipe hot bending shapes of exploitation
Method, the bending quality that aluminium alloy pipe hot bending is shaped and reliability have very important significance.
Content of the invention
In order to solve above-mentioned technical problem, the present invention provides the temperature indicator paste that a kind of aluminium alloy pipe hot bending shapes.This
Invention employed technical scheme comprise that：
A kind of aluminium alloy pipe hot bending forming temperature indicator paste, described temperature indicator paste adopt daily soap, Adeps Bovis seu Bubali, vegetable oil and
Water, is formed by melting and solidification, when described temperature indicator paste is heated, color changes.
Further, described daily soap, the weight percent proportioning of the composition of Adeps Bovis seu Bubali, vegetable oil and water are respectively：Daily fertilizer
Soap accounts for 40～50%, and Adeps Bovis seu Bubali account for 10～20%, and vegetable oil accounts for 10～20%, and remaining is water.
Further, described temperature indicator paste normal temperature state is yellow, is heated to being suitable for the shaping of aluminium alloy pipe hot bending
Temperature range when, temperature indicator paste color from yellow is changed into black, when temperature indicator paste color by black transitions be white
When stop heating.
A kind of aluminium alloy pipe bending forming method, comprises the steps：
Step 1：By temperature indicator paste even application in aluminium alloy pipe profiled surface to be bent；
Step 2：To aluminium alloy pipe, place to be bent carries out flame heating；
Step 3：After temperature indicator paste color tips enter the temperature range being suitable for bending forming, aluminium alloy pipe is carried out curved
Bent shaping；
Step 4：The aluminium alloy pipe of bending forming after the assay was approved, wipes aluminium alloy pipe surface, erasing surface temperature instruction
Cream is it is ensured that the cleaning of aluminium alloy pipe.
Further, in described step 1, by temperature indicator paste even application at aluminium alloy pipe shaping to be bent just
Face, the area of application is more than region to be bent.
Further, in described step 2, flame heated region should strictly be controlled, it is to avoid beyond the area of application.
Further, in described step 3, temperature indicator paste color tips enter the temperature range being suitable for bending forming, when
When temperature indicator paste color from yellow is changed into black, shaping is curved to aluminium alloy pipe, when temperature indicator paste color by
When black transitions are white, stop flame heating.
Brief description
Fig. 1 uses the bending method flow chart of temperature indicator paste for the present invention；
Fig. 2 uses the aluminium alloy pipe product figure of temperature indicator paste bending forming for the present invention.
Specific embodiment
In conjunction with embodiment, accompanying drawing, the invention will be further described：
The present invention provides the temperature indicator paste that a kind of aluminium alloy pipe hot bending shapes, and this temperature indicator paste adopts daily soap, cattle
Oil, vegetable oil and water, the daily soap of the weight percent proportioning respectively 40～50% of each component, 10～20% Adeps Bovis seu Bubali, 10～20%
Vegetable oil, remaining be water.Temperature indicator paste passes through melting and solidification is formed, and normal temperature state is yellow, is heated to being suitable for aluminum conjunction
During the temperature range that golden tubing hot bending shapes, color from yellow changes, and when temperature exceeds suitably interval, color enters one
Step changes.
As depicted in figs. 1 and 2, each weight percentages of components of temperature indicator paste that the present embodiment uses is respectively for 45% day
With soap, 15% Adeps Bovis seu Bubali, 20% vegetable oil, remaining is water.
Using the aluminium alloy pipe bending forming method of this temperature indicator paste, processing step is as follows：
Step 1：By temperature indicator paste even application in aluminium alloy pipe 1 profiled surface to be bent it is desirable to coating scope 2 should comprise
Tubing front surface region to be bent.
Step 2：Using alcohol blast burner etc. to aluminium alloy pipe place to be bent carry out flame heating it is desirable to flame heating model
Enclose 3 and should not exceed coating scope 2.
Step 3：It is desirable to treat temperature after the temperature indicator paste color tips suitable temperature range of entrance coated by place to be bent
The color from yellow of degree indicator paste is changed into and is curved shaping to aluminium alloy pipe during black, when temperature indicator paste local presents
When white, should stop heating.
4th step, hot bending forming tube after the assay was approved, dips alcohol wipe the area of application using silk, removes knee
Temperature indicator paste it is ensured that product cleaning.
It should be noted that being the present invention to be schematically illustrated and illustrates above, those skilled in the art should
