Abstract
The utility model relates to a special combined mold for an elliptical or melon seed-shaped single or dual-metal integral finned tube, which is composed of an upper mold sheet group 2, a lower mold sheet group 2', an upper mold cover 1 and a lower mold cover 1', wherein one end of the upper mold sheet group and the lower mold sheet group forms a semi-elliptical shape or a melon seed shape, the other end forms a planar shape, and the upper mold cover and the lower mold cover form an n shape; the quantity of mold sheets of the upper mold sheet group and the lower mold sheet group corresponds to that of fins of a finned tube 3, the semi-elliptical or melon seed-shaped ends of the upper mold sheet group and the lower mold sheet group are orderly inserted between each upper fin and each lower fin of the finned tube, the upper mold cover and the lower mold cover are covered on the other end and are arranged under a press, and then an elliptical or melon seed-shaped finned tube is formed by one-step pressing. The combined mold has the advantages of simple and convenient production, high work efficiency and low manufacture cost and ensures the quality of the finned tube.
Description
The utility model relates to a kind of particular manufacturing craft of producing various coolers with finned tube, is specifically related to a kind of ellipse or the single, double metal integral finned tube of melon seeds shape special combination mould.
The used finned tube of transformer forced oil-circulation forced air cooler has circular single, double metal integral finned tube and oval around chip, casing fin tube at present.The former rings radiating effect because of its parent tube for the circular big face of windage that causes.Though latter's windage is little, because of around sheet, overlap the machining process complexity, two kinds of Metal Contact thermal resistances greatly also influence radiating effect.For overcoming above-mentioned weak point, now designed the single, double metal integral finned tube of a kind of ellipse or melon seeds shape.This finned tube windage is little, and distinguished and admirable area is big, and thermal contact resistance is little, thereby has improved radiating effect, has reduced the manufacturing cost of cooler, and the power of motor of exhaust system is also corresponding to be reduced, and has reached purpose of energy saving.But still there is not the particular manufacturing craft of producing this cast at present.
The purpose of this utility model is to provide a kind of special combination mould of producing ellipse or the single, double metal integral finned tube of melon seeds shape.
The utility model is achieved in that a kind of ellipse or the single, double metal integral finned tube of melon seeds shape special combination mould, and it comprises: upper and lower matrix group and upper and lower die cap.Upper and lower matrix group one end is ellipse or melon seeds shape, the other end is a planar shaped, upper and lower die cap is " " shape, the matrix number of upper and lower matrix group is corresponding with the fin number of finned tube, its half elliptic or melon seeds shape end insert between upper and lower each fin of finned tube successively, the other end covers, following die cap, places under the press, once is pressed into ellipse or melon seeds shape finned tube.
Assembling die of the present utility model uses, and finned tube quality simple, convenient, compacting is good, low cost of manufacture, and operating efficiency is good, is a kind of special combination mould of producing ellipse or the single, double metal integral finned tube of melon seeds shape.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is an embodiment schematic diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model being done one describes in detail:
Shown in Fig. 1-2, the utility model is a kind of ellipse or the single, double metal integral finned tube of melon seeds shape special combination mould.It by upper and lower matrix group 2,2 ' and upper and lower die cap 1,1 ' form.Upper and lower matrix group 2,2 ' one end are half elliptic or melon seeds shape, and the other end is a planar shaped, and upper and lower die cap 1,1 ' is " " shape.
As shown in Figure 3, during use, upper and lower matrix group 2,2 ' half elliptic or melon seeds shape end are inserted 5 of finned tube 3 each fins successively, the other end covers upper and lower horizontal lid 1,1 ' place one or more (according to press pressure size) under the press, once is pressed into ellipse or melon seeds shape finned tube.Defeat on footpath, 5 ends of fin and parent tube 6 because of matrix, so fin 5 is injury-free, and make footpath, the end, parent tube, fin all becomes ellipse or melon seeds shape.
Embedding must be tighter between fin because of the matrix after the compacting, can look by image pattern 1, place left and right top board 4,4 ' in upper and lower matrix group 2,2 ' both sides, upper and lower matrix group 2,2 ' and top board 4,4 ' contact-making surface be the inclined-plane, drive top board 4,4 ' separately with hydraulic press with matrix group 2,2 '.
The single, double metal integral finned tube of the ellipse of this assembling die production or melon seeds shape can be used for the various coolers that systems such as machinery, air-conditioning, electric power, petrochemical industry use.
