Description
Technical field
The present invention relates to a kind of compression casting composite bottom boiler and die cast manufacturing process thereof.
Background technology
At present, the composite bottom boiler that can be used for electromagnetic oven mostly is and adopts the mechanical riveted formula composite bottom boiler of machinery with stainless iron egative film and the extrusion modling of pot body, because this composite bottom boiler bottom of pot body has the riveted nail, the riveted through hole is arranged on the stainless iron egative film, the actual effective area of metal part that its bottom produces eddy current is less, so it is complicated to exist mould and parts to make, the thermal efficiency is lower, defectives such as bonding strength difference; And the out-of-flatness of stainless iron egative film not only influences attractive in appearancely, and also can cause damage to the electromagnetic oven surface.Thus, notification number is that the Chinese utility model patent of CN201015535Y discloses a kind of compression casting composite bottom boiler, and it is to have blind hole on the stainless iron compound bottom sheet, when die casting pot body and compound bottom sheet is merged.Because it is to rely on the projection of the aluminium liquid formation that is filled in the blind hole that compound bottom sheet and pot body are linked together, if compound bottom sheet is thinner, then the degree of depth of blind hole is more shallow, and the bonding strength between compound bottom sheet and the pot body is just low; If compound bottom sheet is thicker, then there is the high shortcoming of production cost undoubtedly.In addition, the compound bottom sheet of this composite bottom boiler mainly relies on the projection that forms in the blind hole with being connected of pot body, because the thermal coefficient of expansion of aluminium alloy and stainless iron differs, this composite bottom boiler is under hot and cold alternating action, and the heat-resistant anti-fatigue performance is lower, can influence its service life undoubtedly; And its compound bottom sheet is a tabular, and reliability of positioning was poor after compound bottom sheet was put into compression mod, and its waster rate is higher.
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 manufacturing process is simple, compression casting composite bottom boiler that the finished product rate is high and die cast manufacturing process thereof.
The objective of the invention is to realize as follows: a kind of compression casting composite bottom boiler, comprise aluminum alloy pan body and stainless iron compound bottom sheet, be characterized in that the stainless iron compound bottom sheet is provided with some fasteners, stainless iron compound bottom sheet periphery is provided with the flange that coats pot body lower periphery, and aluminum alloy pan body bottom and stainless iron compound bottom sheet are cast into one by die casting machine.
Fastener of the present invention is the stud shape, can the rule or be located at brokenly on the stainless iron compound bottom sheet.
Fastener of the present invention also can be netted and be located on the stainless iron compound bottom sheet.
Fastener of the present invention also can be hole flanging limit shape, can the rule or be located at brokenly on the stainless iron compound bottom sheet.
The manufacturing process of above-mentioned compression casting composite bottom boiler may further comprise the steps:
(1) makes compound bottom sheet:, fastener is welded on the stainless iron compound bottom sheet with the drawing of stainless iron compound bottom sheet;
(2) place the stainless iron compound bottom sheet: the stainless iron compound bottom sheet is put into compression mod cover half die cavity;
(3) die casting: behind the die casting machine matched moulds, with temperature is that 600-700 ℃, injection ratio pressure are that the liquid aluminium alloy of the molten condition of 20-80Mpa is filled into die cavity with the jet velocity of 20-60m/s, loading time is 0.02-0.07S, after treating that aluminium liquid is full of die cavity, be one by the die casting machine die cast with pot body and above-mentioned stainless iron compound bottom sheet;
(4) surface treatment: after treating the compression casting pan cooling, remove the overlap on the pot body, carry out sandblast, spray treatment again, can make compression casting composite bottom boiler.
Because this compression casting pan pot body and stainless iron compound bottom sheet are cast into one, any space that molten aluminum liquid can be filled on the stainless iron compound bottom sheet when die casting forms an integral body, the fastener that also will be located at simultaneously on the stainless iron compound bottom sheet is fused into one with pot body bottom, therefore the stainless iron compound bottom sheet is very firm with being connected of pot body, need not to adopt thicker stainless iron compound bottom sheet, can control the cost of product effectively, and compression casting pan can not be affected under hot and cold alternating action yet, and heat-resistant anti-fatigue stability is high.In addition, because stainless iron compound bottom sheet periphery has the flange that coats pot body lower periphery, and it can be positioned on the compression mod cover half when die casting reliably, improves the sealing of compression mod die cavity simultaneously, can prevent effectively that aluminium liquid from flowing to the compound bottom sheet back side, thereby improve the yield rate of product; And the flange on the stainless iron compound bottom sheet also enlarged the effective area that the bottom produces the metal part of eddy current, thereby improved the thermal efficiency of compression casting pan.In addition, the fastener 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.
