Description
Technical field
The invention belongs to the cooker manufacture technology field, specifically is a kind of machining technology of redriving aluminum alloy pan.
Background technology
In the prior art, redriving aluminum alloy pan is a compound redriving piece on the aluminium matter semi-finished product the bottom of a pan.This pan except the thermal efficiency and life-span than traditional pan improves to some extent, the more important thing is applicable to new kitchen range such as electromagnetic ovens.
The technology of present compound redriving piece is more complicated all, is applied to a lot of big machineries, and for example pressure remains on the press of bar up to a hundred, and the dwell time is very long, and pressurize often.So just can obtain meeting the redriving aluminum alloy pan of quality standard, and in the process of pressurize, deviation very easily appears in default working process parameter, makes the constant product quality that obtains poor.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the present invention proposes a kind of new machining technology of redriving aluminum alloy pan, and concrete technical scheme is as follows:
A kind of machining technology of redriving aluminum alloy pan comprises step:
1) stretches for the first time: choose a pot body sheet shape blank and stretch, obtain the blank of pot body;
2) compound redriving piece on the bottom of a pan: the redriving piece strike-on is arrived the bottom of a pan lower surface;
3) stretching for the second time: step 2) a pot body that obtains stretches once more according to designing requirement, makes a pot body reach design thickness and height;
4) subsequent treatment: the pot body is carried out the pot mouth be carried out to and spray treatment, obtain finished product with a pot body;
Described step 2) may further comprise the steps in:
2.1) just weld redriving piece: get redriving piece, earlier redriving piece spot welding is fixed on a pot body bottom surface, again the following table facing sand hair and the sandblast of redriving piece;
2.2) the strike-on process: earlier bottom of pot body up left-hand thread be positioned on the high frequency heater, startup high frequency heater makes redriving piece and bottom of pot body temperature rise to 450～550 ℃, the duration is 5～60 seconds;
Again bottom of pot body up left-hand thread be positioned on the strike-on machine, carry out strike-on, make a redriving piece and a pot body strong bonded.
The material of pot body is the pot body of aluminium alloy, 304 stainless steels or 430 stainless iron materials in the described step 1); Described step 2) redriving piece is 430 stainless iron redriving pieces in;
Pot body for 304 stainless steels and 430 stainless iron materials also adds the strike-on product of layer of aluminum in the middle of bottom of pot body and 430 stainless iron redriving pieces.
Also will clear up the pot surface after step 1) finishes: with the mass ratio of dilution is that 1: 30 sodium hydroxide solution cleans, and is in rare nitric acid of 150 with the mass ratio that dilutes again.
Described step 2.2) in, on the high frequency heater, the voltage of high frequency heater is that 10000V, cathode current are that 1.2A is anode current 9.5A.
Described step 2.2) in, what the strike-on machine was selected for use is that 1000-1300 ton strike-on machine, strike-on time are 1.7 seconds.
In the described step 4), press mouth earlier, make pot mouthful moulding, the car limit then of pot body; Again the bottom of a pan Vehicle Processing moulding of pot body pot body; Carry out a pot body spraying at last, obtain finished product.
Compared with prior art, the steady quality of simple, less demanding, the product of technology of the present invention to equipment.For the product that makes, thermal conductivity height, energy savings; The pot body is slim and graceful, easy to use; Easy cleaning, the not sticking end, fuel-efficient.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
Among the figure, aluminum alloy pan pot body (1), stainless iron redriving piece (2), finished product (3).
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
In this example, blank is selected 6mm aluminium alloy aluminium flake for use, and redriving piece is selected 430 stainless iron redriving pieces for use.Technical process is as follows:
1) stretches for the first time: select for use 6mm aluminium alloy aluminium flake to stretch, stretch and highly arrive 30mm.
2) surface clean: being that 1: 30 sodium hydroxide solution cleans with the mass ratio of dilution after the moulding, is in rare nitric acid of 150 with the mass ratio that dilutes again.
3) just weld redriving piece: select the i.e. 430 stainless iron redriving pieces of 0.5mm stainless iron redriving piece for use, clean up; Aluminum alloy pan pot body and the spot welding of stainless iron redriving piece are fixed, one facing sand hair and the sandblast of stainless iron redriving piece;
4) strike-on process: aluminum alloy pan bottom of pot body left-hand thread up is positioned on the high frequency heater, and voltage arrives 10000V, cathode current 1.2A, anode current 9.5A, the stainless iron redriving piece is rapidly heated, and makes aluminum alloy pan bottom of pot body temperature rise to 450-550 ℃, and the duration is 50-60 second;
Again the aluminum alloy pan bottom of pot body up left-hand thread be positioned on the 1000-1300 ton strike-on machine, adjust 1.7 seconds strike-on time, carry out strike-on.Make stainless iron redriving piece and aluminum alloy pan pot body strong bonded.
5) aluminum alloy pan pot body succeeding stretch: the attenuation of pot body, high elongation is to 41mm
6) subsequent treatment: press mouth to make the moulding of aluminum alloy pan pot body pot mouth, car limit then.The bottom of a pan Vehicle Processing moulding of aluminum alloy pan pot body (1) pot body.The spraying of pot body obtains finished product.
This technology also is applicable to the pot body of 304 stainless steels and 430 stainless iron materials, just adds the strike-on product of layer of aluminum in the middle of bottom of pot body and the 430 stainless iron redriving pieces.
