Description
Technical field
The present invention relates to a kind of technical field of the multiple end of heat of alusil alloy compression casting pan.
Background technology
Traditional aluminium alloy stretches pot and alusil alloy compression casting pan for the ease of using on electromagnetic oven, usually need be on bottom of pot body be multiple the compound bottom sheet of energy magnetic conducting and heating, thereby reach the effect of multi-functional use.Traditional technological means of the multiple end has at present:
1. adopt the riveted joint cold-press process to carry out the multiple end, promptly on the pot body, make the structure of column, make cavernous structure on the compound bottom sheet, adopt the technology of colding pressing, compound bottom sheet and pot body consolidation.The shortcoming of this technology is that the thermal efficiency is low, forms the space because cause easily between compound bottom sheet and the aluminum pot, and the heat conduction is descended.
2. employing hot-pressing technique, directly compound with carrying out HTHP after pot body and the multiple base plate heating, but need serve as adhesive at a kind of metal of adding between pot body and the multiple base plate, and the compound time is long especially, generally need 5min～30min, production efficiency is low, the cost height.
3. adopt the strike-on technology, the strike-on production technology in the similar Stainless steel pressure cooking-vessel the bottom of a pan, adopt the above friction press of 1000T to feel secure, its compound principle is to weld after utilizing the friction press instant impact to cause the material faying face to produce high temperature, belongs to the friction welding technology category.Also have, its friction press equipment price costliness, the standing charges height, every equipment investment is all more than 1,000,000 yuan, and annual maintenance cost also needs more than the hundreds of thousands unit, and some little factories do not have strength, are difficult to realize producing in batches.
These technological means of multiple end are not very desirable, need do further improvement.
Summary of the invention
At the bottom of the compound pot that primary technical problem to be solved by this invention provides a kind of practicality rational in infrastructure, manufactures easily, production efficiency is high.
Manufacture method at the bottom of the compound pot that another technical problem to be solved by this invention provides a kind of practicality rational in infrastructure, manufactures easily, efficient is high.
The present invention solves the technical scheme that above-mentioned primary technical problem adopts: at the bottom of a kind of compound pot, it includes bottom of pot body and answers the compound bottom sheet of using at the end, compound bottom sheet covers and is fixed on the bottom of pot body, it is characterized in that bottom of pot body and compound bottom sheet apparent surface form the lines of cooperation respectively, by first hot-extrusion method, cooling means makes compound bottom sheet produce the atom Diffusion Welding and compound being fixed as one with the crystal boundary face that combines in the bottom of a pan under the interaction of heat and extruding force again.
Described lines adopts the wire drawing lines.
Described lines is to adopt 80～100 purpose abrasive bands that wire drawing is carried out on its surface, is distributed in the steel disc of whole compound usefulness and needs on the compound surface, the bottom of a pan.
Improve, described bottom of pot body is distributed with air discharge duct again, is convenient in the extrusion process residual gas be discharged, and makes the multiple end smooth, reduction in the numbers of seconds.
Preferably, described air discharge duct is to be communicated with by the air discharge duct of a plurality of concentric annular distribution and a plurality of radially-arranged air discharge duct to constitute.
At last, described air discharge duct width is at 0.8～1mm, and the degree of depth is at 0.5～0.8mm.
The present invention solves the technical scheme that above-mentioned another technical problem adopts: the manufacture method at the bottom of a kind of compound pot, it is characterized in that: the composite surface of bottom of pot body produces lines and air discharge duct, accordingly, the composite surface of compound bottom sheet also produces the cooperation lines, the pot body is heated at least more than 400 ℃, heat compound bottom sheet more than at least 600 ℃, then compound bottom sheet and bottom of pot body are fitted with aspect relative engagement mode according to lines, adopt hot extrusion mode consolidation, normal temperature cooling down gets final product.
The technical scheme that described another technical problem adopted is: need to heat on the hot extrusion composite die, usually the temperature of mould should be controlled between 200～300 ℃, keeping pot and composite sheet not to cool off too soon before firmly compound, so that influence bond strength between the two.
Described its specific pressure of hot extrusion mode is controlled at 50～80Kg/mm
2Scope, 2～10 seconds time, the time is short more good more.
The nature cooling is adopted in described cooling.
Described vent groove configuration is referring to top description.
Compared with prior art, the invention has the advantages that: the pot body is before heat is compound, the composite surface of pot body need carry out drawing pattern to be handled, the composite surface of compound bottom sheet also needs to carry out drawing pattern to be handled, in the time of necessary in conjunction with vent groove configuration, and both are before heat is compound, after its silking is placed in the same way, diffusion reaction takes place in the molecule of two kinds of metals mutually under HTHP, thereby fused on the crystal boundary face of two kinds of metals is one, increased both compound firmness so greatly, and the production efficiency height, production cost reduced.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Anticipate as shown in the figure, at the bottom of a kind of compound pot and manufacture method, composite surface at the bottom of pot body 1 of aluminium matter produces wire drawing lines 1.1, as improvement, before wire drawing, composite surface at the bottom of pot body 1 of aluminium matter can also produce air discharge duct 3, air discharge duct is to be communicated with by the air discharge duct 3.1 of 4 concentric annular distribution and 4 radially-arranged air discharge ducts 3.2 to constitute, 4 radially-arranged air discharge ducts 3.2 present the even characteristic distributions of circumference, the design of air discharge duct width is at 0.8～1mm, depth design is at 0.5～0.8mm, certainly, air discharge duct also can be designed to the layout of other shapes, as radiation profile of concentric or the like, lines 1.1 adopts the vertical bar drawing pattern, the wire drawing lines is finished on the wire drawing machine with 80～100 purpose abrasive bands, be distributed in border circular areas, accordingly, the composite surface with compound bottom sheet 2 of using the same method also produces and cooperates vertical bar wire drawing lines 2.1, be distributed in border circular areas, the pot body is heated at least more than 400 ℃, heat compound bottom sheet more than at least 600 ℃, under the usual conditions, the temperature in the compound bottom sheet contact the bottom of a pan, it is higher that the tapping temperature of actual compound bottom sheet can consider that the cooling situation adds again, the heating upper limit is to guarantee that at the bottom of the compound pot be limit smoothly, the technical staff can come choose reasonable according to own working condition and material property, can not make compound bottom sheet material or bottom of pot body too softening, then compound bottom sheet 2 and bottom of pot body 1 are fitted according to lines relative engagement mode, its basic demand is that the wire drawing lines must be placed in the same way, adopt hot extrusion mode consolidation, in hot pressing, compound specific pressure is controlled at 50～80Kg/mm
2Scope, within 5～10 seconds with compound bottom sheet 2 with after bottom of pot body 1 combines, with the hydraulic press more than several kilotons directly with both consolidations, naturally cooling gets final product then, the production efficiency height, make compound bottom sheet 2 be compounded in bottom of pot body 1 like this, constituted compound pot, be convenient on electromagnetic oven, use by the texture structure that cooperates.
