Abstract
A method for manufacturing a radiator without machining is called as a method for manufacturing a radiator without machining. The radiator is a steel body or a steel-aluminium combination body, and is characterized in that molten iron or molten aluminium is cast on a steel pipe to form a radiator, and the steel pipe plays a role in sealing and connecting. The steel pipe is turned with joint press threads in advance. And after casting and forming, cutting off a casting head to obtain a finished product. The radiator only has inferior products and does not produce waste products, the core making process and the raw materials, the leakage detection, the machining and other processes are saved, the radiator has light weight, large heat dissipation capacity, high connection strength and few accessories, and is particularly suitable for a steam heating system of a high-rise building.
Description
The present invention relates to the heating system installing engineering, specifically: be a kind of radiator (radiator) manufacture method in the heating system.
In existing numerous kind radiators, have: one, casting radiator: (1) aerofoil profile radiator, as: big or small 60 types, " the garden wing, square aerofoil profile "; (2) column type radiator: as two posts, four posts, five posts; Two, steel radiator: as (1) welding comb type; (2) steel serial finned type; (3) punching press wooden partition type; Three, other materials radiator: as ceramic mould, the engineering plastic type radiator.
Above all kinds radiator all has various weak points: as: big or small 60 types, weight is big, and radiating efficiency is low, this class of four posts, complex process, parts is many, investment is installed greatly.Steel string sheet is more satisfactory a kind of radiator, but because of complex process, steel string lamellar body is thin, easily gets rusty, and the string sheet life-span is long not as steel pipe; The wooden partition formula is not corrosion-resistant, and bearing capacity is low.Ceramic mould, engineering plastic type are difficult to promote because of all multifactor.
The objective of the invention is for manufacturer design that a kind of technology is simple, raw materials consumption is few, profit margin is high, again for the user provides that a kind of radiating efficiency height, bearing capacity are big, long service life, few a kind of comparatively ideal radiator---the method for making heat radiator without machining of accessory easy to assembly.
Method for making heat radiator without machining is to realize its purpose from three aspects:
1, heating installation coremaking operation and raw material have been removed from.
2, saved the machined preface of radiator.
3, the bearing capacity and the heat dissipation capacity of radiator have been improved.
Fig. 1 is a kind of single tube free processing heating radiator.Fig. 2 is the double hose free processing heating radiator.Among the figure:
(1) is the steel pipe that has the screw thread of car system connecting tube in advance; The screw thread at steel pipe two is an anti-plus thread;
(2) be to cast in radiating wing on the steel pipe with molten iron or aluminium liquid;
Connect screw thread when (3) being the radiator assembling;
(4) be that expression exempts to add connecting mode in the radiator, available silk connected;
(5) be the outer connection mode of expression free processing heating radiator, available movable joint connects.
Method for making heat radiator without machining sand casting process flow process is: join molding sand → moulding → lower Tube core → ventilation (cast aluminium) → water flowing (cast iron) → casting → cooling → sand removal → cutting is watered Rising head → quality inspection grades.
The present invention compared with prior art has the following advantages:
(1) after the cast molding, except the cutting dead head, do not carrying out machining;
(2) removed from all core manufacturing crafts, operation, (join core sand, moulding core, oven dry Lower core, clear core sand etc.);
(3) good seal performance, the bearing capacity height is applicable to the high pressure hot air heating;
(4) the free processing heating radiator raw materials consumption is few, (without core sand, core-type mold, the two-tube 50 centimeter length free processing heating radiator weight of a slice only be big 60 1/2,18.8 kilograms of calculated values comprise steel pipe weight);
(5) radiating efficiency and steel string sheet are approximate, but the life-span of radiating wing than the string length of a film, and clear up dust fall easily, good looking appearance is easily made than steel string sheet cost is low.Be not afraid of and freeze.
(6) only produce substandard products, do not produce waste product, can not produce the seepage phenomenon of other types casting radiator, the free processing heating radiator of this method manufacturing is specially adapted to heat pipe heating installation.
(7) free processing heating radiator is easy to assembly, and the accessory consumption is few in addition, and expense is low;
(8) free processing heating radiator can series, parallel, the connection in series-parallel assembling, uses that can laterally superpose also can horizontally-arranged assembling use.(can not erect use) as four column types
The production technology of free processing heating radiator can adopt multiple traditional sand casting, but also color ceramic mold casting, and the combination die cast is easy to streamline production.
Free processing heating radiator has carried out the test of steel aluminium combination, and is respond well.
Make heat pipe radiating fin with the method: the vacuum tube that adds the outer wall casting radiating wing of heat-transfer working medium promptly.
(9) the free processing heating radiator cost of equipment of this method production is few, saves core manufacturing craft equipment and machining equipment, and medium and small producer and individuality all can use this method to produce small investment, instant effect.
Claims (10)
1, a kind of free processing heating radiator manufacture method: it is characterized in that iron and steel or steel aluminium combination, is to cast in the radiator that forms on the steel pipe that has pre-threaded with molten iron or aluminium liquid.(hereinafter to be referred as method)
2, the described method steel pipe according to claim 1 plays sealing and anastomosis, and radiating wing is that molten iron or aluminium liquid cast on the steel pipe.
3, the connection screw thread according to the described method of claim 1 processes in advance, promptly can be internal thread, also can be external screw thread.
4, the connection screw thread according to the described method of claim 1 two is positive left-hand thread.
5, free processing heating radiator according to claim 1 can be made single tube and also can make two-tube or multitube radiator.
6, be that Fang Yi also can be the garden wing according to described ground of claim 1 free processing heating radiator transverse shape.
7, according to described ground of claim 1 free processing heating radiator behind casting, cut away dead head, no longer carry out machining.
8, produce the heat pipe radiator of iron and steel combination or the combination of steel aluminium according to described ground of claim 1 free processing heating radiator production technology.
9, the nipple of radiator connection according to claim 1 is positive left-hand thread (to a silk); The fishing box that connects radiator end face and connection levels.
10, can be made into the series of products of multiple Guan Jing according to the described radiator of claim 1.
