Abstract
The invention relates to a fit-typed die-casting composite bottom pan, comprising an aluminium alloy pan body and a composite bottom sheet which is fit at the bottom of the pan body; the fit-typed die-casting composite bottom pan is characterized in that the pan is formed by the rolling and composing of a composite material sheet and a stainless steel sheet; the composite material sheet is provided with a plurality of circular concave troughs with internally inclined side wall; the bottom of the pan body is provided with a plurality of circular convex ribs which are embedded into the circularconcave troughs; after being fit, the circular concave troughs and the circular convex ribs are rabbeted with each other; the composite material sheet is made of pure aluminium or aluminium alloy or material with the linear expansion coefficient approximate to the aluminium alloy. The invention also relates to a manufacture process used for the fit-typed die-casting composite bottom pan; the manufacture process of the invention is used for preparing the fit-typed die-casting composite bottom pan by the steps as follows: composite bottom sheet preparing, die casting of aluminium alloy pan body,flap edge removing of the pan body, gold processing, fitting, surface disposing, etc. The fit-typed die-casting composite bottom pan has the advantages of firm connection of the composite bottom sheet, high thermal efficiency, good heat-resistance fatigue performance, simple manufacture process, and the like, and is a cooker which is especially suitable for being used for induction cookers.
Description
Technical field
The present invention relates to a kind of stitching type compression casting composite bottom boiler and manufacture method thereof.
Background technology
At present, the composite bottom boiler that can be used for electromagnetic oven mostly is mechanical riveted formula composite bottom boiler, because this composite bottom boiler bottom of pot body and stainless iron compound bottom sheet are by closing-up, the riveted through hole is arranged on the stainless iron compound bottom sheet, the actual effective area of metal part that its bottom produces eddy current during use is less, so the thermal efficiency is lower, and it is complicated to exist mould and parts to make, defectives such as bonding strength difference; And since the stainless iron compound bottom sheet by closing-up, so smooth inadequately bottom it, not only influence attractive in appearancely, damage is also caused on the electromagnetic oven surface easily.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind ofly be connected firmly, thermal efficiency height, the heat-resistant anti-fatigue performance is stable and simple stitching type compression casting composite bottom boiler of manufacturing process and manufacture method thereof.
The objective of the invention is to realize as follows: a kind of stitching type compression casting composite bottom boiler, comprise the aluminum alloy pan body and be pressed together on the compound bottom sheet of bottom of pot body, be characterized in that compound bottom sheet is by composite material sheet with stainless iron plate is rolling is composited, other approaching material of composite material sheet employing fine aluminium or aluminium alloy or linear expansion coefficient and aluminium alloy is made, composite material sheet is provided with oblique annular groove in some sidewalls, bottom of pot body is provided with the annular convex rib of some embedding annular grooves, is the joggle shape after the pressing between annular groove and the annular convex rib.
The manufacture method of above-mentioned stitching type compression casting composite bottom boiler may further comprise the steps:
(1) makes compound bottom sheet: a. with composite material sheet and the rolling compound bottom sheet that is compounded to form of stainless iron plate; B. the compound bottom sheet stamping-out is shaped; C. on compound bottom sheet, process annular groove;
(2) pack alloy pot body: with aluminum alloy pan body die cast;
(3) pot body deflashing and metalworking: deflashing, then the pot mouth is carried out metalworking along portion;
(4) pressing: adopt machinery that compound bottom sheet is pressed together on bottom of pot body;
(5) surface treatment: surface treatment: sandblast, spray treatment can make stitching type compression casting composite bottom boiler.
Because composite material sheet is provided with oblique annular groove in some sidewalls, the annular convex rib that is located at the aluminium alloy bottom of pot body embeds in the annular groove, compound bottom sheet is pressed together on annular groove and annular convex rib are the joggle shape behind the bottom of pot body, therefore can make compound bottom sheet very firm with being connected of pot body, what can effectively prevent compression casting composite bottom boiler takes off end phenomenon, thereby prolongs the service life of compression casting composite bottom boiler.Because composite material sheet is close with the linear expansion coefficient of pot body, so compression casting pan is subjected to the influence of hot and cold alternating action minimum, heat-resistant anti-fatigue stability is high.In addition, the compound bottom sheet among the present invention is simple in structure, convenient for production, and whole manufacturing process is also very simple, can reduce production costs greatly, improves competitiveness of product effectively.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 expression aluminum alloy pan body; 2 expression composite material sheets; The stainless iron plate of 3 expressions; 4 expression annular convex ribs; 5 representative ring connected in stars.
The specific embodiment
The invention will be further described below with reference to accompanying drawing and by embodiment.
With reference to Fig. 1, stitching type compression casting composite bottom boiler comprises aluminum alloy pan body 1 and is pressed together on the compound bottom sheet of bottom of pot body, compound bottom sheet is by composite material sheet 2 and stainless iron plate 3 rolling being composited, oblique annular groove 5 in some sidewalls is arranged on the composite material sheet 2, the annular convex rib 4 of some embedding annular grooves 5 is arranged at pot body 1 bottom, is the joggle shape between annular groove 5 and the annular convex rib 4 after the pressing.In order to improve the heat-resistant anti-fatigue stability of compression casting pan, composite material sheet 2 can adopt the approaching material of fine aluminium or aluminium alloy or other linear expansion coefficient and aluminium alloy to make.Above-mentioned compression casting composite bottom boiler can following technology manufacturing: at first make compound bottom sheet: with composite material sheet 2 and the stainless iron plate 3 rolling compound bottom sheets that are compounded to form, the compound bottom sheet stamping-out is shaped, then Vehicle Processing annular groove 5 on compound bottom sheet again; Next is a pack alloy pot body: with aluminum alloy pan body die cast; Then carry out pot a body deflashing and a metalworking: deflashing, then the pot mouth is carried out metalworking along portion; Be pressing then: adopt machinery that compound bottom sheet is pressed together on bottom of pot body; Be surface treatment at last: sandblast, spray treatment can make a kind of stitching type compression casting composite bottom boiler.
