Description
Technical field
The utility model relate generally to heating installation is specifically related to a kind of steel radiator and the steel heating installation with this radiator.
Background technology
Existing steel radiator 200 as shown in figure 13, by steel joint part 210 on, steel joint part 220 and constitute once with a steel tubular part 230 of last steel joint part 210 and following steel joint part 220 seal weldings.Last steel joint part 210 is identical with following steel joint part 220 structures.As Figure 14 and shown in Figure 15, the outside round ladder interface section 252 of protrusion that last steel joint part 210 and following steel joint part 220 all have a housing parts 260 and the circle that outwards protrudes that forms on the following shell wall of housing parts 260 is sent out interface section 242 blue and formed on shell wall on the housing parts 260.
The manufacture process of existing steel radiator 200 is as follows:
As Figure 16 and shown in Figure 17, steel plate with certain thickness and size is struck out second housing 240, the circles that housing lower half 240 has half housing parts 241 and two circles that outwards protrude that form on the shell wall of half housing parts 241 are sent out interface section 242, two blue and outwards protruded send out interface section 242 each interval certain distances blue;
As Figure 18 and shown in Figure 19, steel plate with certain thickness and size is struck out a upper half-shell 250, the two round ladder interface sections of outwards protruding, 252, the two outside round ladder interface section 252 each interval certain distances that protrude that upper half-shell 250 has half housing parts 251 and forms on the shell wall of half housing parts 251;
As Figure 20 and shown in Figure 21, upper half-shell 240 and housing lower half 250 seal weldings are in the same place, for example by inferior arc welding, form a joint housing 270;
Figure 20 and joint housing shown in Figure 21 270 are cut open from the centre, obtained as Figure 14 and last steel joint part 210 and following steel joint part 220 shown in Figure 15, last steel joint part 210 all has a cutting mouth 245 with following steel joint part 220;
Cross section is connected with the cutting mouth 245 of last steel joint part 210 and following steel joint part 220 respectively by seal welding with the upper and lower end of the surperficial identical steel tubular part 230 of cutting mouth 245, for example, obtain steel radiator 200 as shown in figure 13 by inferior arc welding.
Being constructed as follows of steel heating installation 300 with the manufacture process of steel heating installation 300 of existing steel radiator 200 and manufacturing:
As Figure 22 and shown in Figure 23; two steel radiators 200 are overlaped; make two round ladder interface sections of outwards protruding 252 of a steel radiator 200 insert two in outwards the circles of protrusions send out interface section 242 blue of another steel radiators 200; the two round ladder interface sections 252 of outwards protruding and the circles of two outside protrusions are sent out interface section 242 blue and are matched; and the two 252 pairs of mating areas in round ladder interface section that outwards protrude that stretch into this steel radiator 200 carry out seal welding in the inside of this steel radiator 200; for example; carrying out carbon-dioxide arc welding connects; thereby; two steel radiators 200 are linked together hermetically; obtain as Figure 22 and steel heating installation 300 shown in Figure 23; wherein, the seal plug on two circles that outwards protrude that are welded on a steel radiator 200 send out interface section 242 blue and be welded on advancing on the two round ladder interface sections 252 of outwards protruding of another steel radiator 200; the steel pipe joint of giving vent to anger is not shown.
Figure 22 and steel heating installation 300 shown in Figure 23 have two steel radiators 200.Obviously, adopt said method, can make steel heating installation with two above steel radiators 200.
Existing steel radiator 200 and manufacture method thereof have following shortcoming:
It is different with the structure of round ladder interface section 252 of outside protrusion on the shell wall of the upper half-shell 250 of housing parts 260 that the circle of the outside protrusion on the shell wall of the housing lower half 240 of the last steel joint part 210 of steel radiator 200 and the housing parts 260 of following steel joint part 220 sends out interface section 242 blue, punching press housing lower half 240 needs the different diel of two covers with punching press upper half-shell 250, makes the manufacturing cost height of steel radiator 200.
To two round ladder interface sections of outwards protruding 252 of a steel radiator 200 and another steel radiator 200 two outwards the circles of the protrusions mating area of sending out interface section 242 blue carry out seal welding in the inside of this another steel radiator 200, welding quality is not easy to guarantee, with a plurality of steel radiators 200 by after dressing up a steel heating installation 300 in steel radiator 200 inner sealing soldering group, if leak at welding region generation gas, can't carry out repair welding by welding at steel radiator 200 inner sealings, can only be by carrying out repair welding in steel radiator 200 outside seals welding, because the space outerpace that the steel radiator is 200 is narrow, operate very difficult, often miss one's aim, yield rate is low;
By dressing up a steel heating installation 300 in steel radiator 200 inner sealing soldering group, the operating time is longer with a plurality of steel radiators 200, and can not accomplish needs at any time, at any time assembling, at any time the supply of material could be supplied after crossing certain hour in the time of can only order form being arranged, the shortage flexibility;
With a plurality of steel radiators 200 by after dressing up a steel heating installation 300 in steel radiator 200 inner sealing soldering group, could carry out a kind of color of integral body spray to steel heating installation 300, can not accomplish a kind of color of a steel radiator 200 sprays, a steel heating installation 300 can have multiple color.
