Fig. 2 is the schematic diagram of internal structure of the utility model two halves formula single head heating tube.
Fig. 3 is the surface cross-sectional view of the utility model two halves formula single head heating tube.
Specific embodiment
The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:
Please refer to Fig. 1 and Fig. 2, a kind of two halves formula single head heating tube, including heating wire 10, insulation filler 20, the first gold medal
Belong to casing 31, the second metal sleeve 32, power lead 40 and pedestal 50, the first metal sleeve 31 and the second metal sleeve 32 are
50 top of pedestal is set.First metal sleeve 31 is arranged in parallel with the second metal sleeve 32, and the first metal sleeve 31 and second
There are gap, the first metal sleeve 31 and the second metal sleeves 32 to form two-half structure, the first metal between metal sleeve 32
Casing 31 is connected to far from 50 one end of pedestal by connecting metal sleeve 33 with the second metal sleeve 32.
Heating wire 10 successively passes through inside the first metal sleeve 31, connection metal sleeve 33 and the second metal sleeve 32,
Power lead 40 penetrates pedestal 50 and connect with 10 both ends of heating wire, and pedestal 50 is extended in 40 one end of power lead.In power lead
40 extend 50 one end outer cover of pedestal equipped with insulating gum cover 41, and insulating gum cover 41 plays the role of protection power source conducting wire 40, prevents
The case where only leaking electricity in use.Insulation filler 20 is set to the first metal sleeve 31, connection metal sleeve 33
And in the second internal voids between metal sleeve 32 and heating wire 10.
When the heating wire 10 being arranged in the first metal sleeve 31 and the second metal sleeve 32 is begun to warm up, due to first
Metal sleeve 31 and the second metal sleeve 32 can be heated simultaneously, reach faster heating speed；And in the first metallic sheath
There are gap between pipe 31 and the second metal sleeve 32, when the first metal sleeve 31 and the second metal sleeve 32 it is heated have it is enough
Space expands around simultaneously, cooperates two halves formula single head heating tube with the equipment for needing to heat closer.When stopping adds
When hot, the first metal sleeve 31 compared with the second metal sleeve 32 existing heating tube compared to surface area increase, can quickly into
Row cools, and the first metal sleeve 31 and the second metal sleeve 32 can faster restore original shape, facilitate people from die hole
Middle taking-up.
And first metal sleeve 31, connection metal sleeve 33 and the second metal sleeve 32 are integrated and are made, the first metallic sheath
Pipe 31, connection metal sleeve 33 and the second metal sleeve 32 are made of seamless metal pipe.It is made into integration using seamless metal pipe,
The manufacture of two halves formula single head heating tube is facilitated to process, when seamless metal casing is straight tube, first by heating wire 10 and insulation filling
Object 20 is set in metal sleeve, then being formed seamless metal casing by molding equipment includes the first metal sleeve 31, company
Connect the structure of metal sleeve 33 and the second metal sleeve 32.Whole process is more convenient.
Insulation filler 20 is magnesia powder, and aoxidizing U.S. powder has preferable thermal conductivity and insulating properties, and can satisfy will be electric
While heat transfer caused by heated filament 10 comes out, and play preferable insulation protection.
Heating wire 10 in the first metal sleeve 31 and the second metal sleeve 32 is configured using helical structure, is increased
The contact area of heating wire 10 and insulation filler 20, can dispose longer heating wire in shorter metal sleeve length
10, so that electrical heating power can be improved, to accelerate the heating speed of two halves formula single head heating tube.
Referring to FIG. 3, the cross section of the first metal sleeve 31 and the second metal sleeve 32 is semicircle, and the first metal
The flexure plane of casing 31 and the second metal sleeve 32 is relatively distant from setting.Conveniently when in use, two halves formula single head heating tube is put
Enter into die hole, and semicircular structure can increase the contact area of two halves formula single head heating tube and die hole, improves
Heat conduction efficiency between two halves formula single head heating tube and mold.
The utility model provides a kind of two halves formula single head heating tube, and the first metal sleeve and the second metal sleeve are respectively provided with bottom
Seat top, there are gap, the first metal sleeve and the second metal sleeves to be formed between the first metal sleeve and the second metal sleeve
Two-half structure.When the heating wire being arranged in the first metal sleeve and the second metal sleeve is begun to warm up, due to the first gold medal
Belonging to casing and the second metal sleeve can be heated simultaneously, reach faster heating speed；And in the first metal sleeve and
There are gap between two metal sleeves, when the first metal sleeve and the second metal sleeve is heated enough spaces while around
It expands, cooperates two halves formula single head heating tube with the equipment for needing to heat closer.When heating is stopped, the first metallic sheath
Pipe is compared existing heating tube with the second metal sleeve and is increased compared to surface area, can quickly cool down, the first metal
Casing and the second metal sleeve can faster restore original shape, and people is facilitated to take out from die hole.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
