The utility model is realized by following technical scheme：
A kind of heat-shrink tube malleation pipe expander, including heater box, dilatation mold and cooling chamber, the dilatation mold include importing
Section, linkage section and sizing section, the introduction segment connect with heater box, and the sizing section connects with cooling chamber, the linkage section
Both ends are connected with introduction segment and sizing section respectively, are provided with first passage in the introduction segment, the cross section of the first passage is straight
Footpath is gradually reduced along material conveying direction；The second channel connected with first passage is provided with linkage section, the second channel is in
The diameter of cylinder and second channel is equal to the minimum diameter of first passage；It is provided with the sizing section and is connected with second channel
Third channel, the third channel in cylinder and third channel diameter be more than second channel diameter.
Further, the introduction segment is provided with external screw thread, and heater box is provided with the internal thread coordinated with external screw thread.
Further, the sizing section is provided with the positioning boss of ring-type, and the positioning boss is fixed on the outer of cooling chamber
On wall, sealing ring is provided between positioning boss and cooling chamber.
Further, vacuum chamber is provided between the heater box and cooling chamber, the sizing section is in the position of corresponding vacuum chamber
Put and offer some vacuum holes.
Further, the cooling chamber is provided with cooling water water spraying mechanism.
Beneficial effect is：Compared with prior art, a kind of heat-shrink tube malleation pipe expander, heat-shrink tube to be expanded pass sequentially through importing
Section, linkage section and sizing section, introduction segment is interior to be provided with first passage, and the second channel connected with first passage is provided with linkage section,
The diameter of second channel is equal to the minimum diameter of first passage, and linkage section seals heat-shrink tube to be expanded gas outside in introduction segment
Block, prevent it from entering sizing section, both discharged the pressure outside sizing section pipe, make uniform wall thickness, reduce inclined wall rate, reduce heating again
The loss of pressure in case, save the energy.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing, wherein：
Fig. 1 is the structural representation of heat-shrink tube malleation pipe expander in the utility model embodiment one；
Fig. 2 is the structural representation of heat-shrink tube malleation pipe expander in the utility model embodiment two.
Embodiment
Embodiment one
As shown in figure 1, a kind of heat-shrink tube malleation pipe expander, including heater box 1, dilatation mold and cooling chamber 2, the expansion
Mould includes introduction segment, linkage section and sizing section, and the introduction segment connects with heater box 1, and the sizing section connects with cooling chamber 2
Logical, the both ends of the linkage section be connecteds with introduction segment and sizing section respectively, and the introduction segment is interior to be provided with first passage 31, and described the
The cross-sectional diameter of one passage 31 is gradually reduced along material conveying direction；Second connected with first passage 31 is provided with linkage section
Passage 32, the second channel 32 are equal to the minimum diameter of first passage 31 in the diameter of cylinder and second channel 32；Institute
The third channel 33 for being provided with sizing section and being connected with second channel 32 is stated, the third channel 33 is in cylinder and third channel
33 diameter is more than the diameter of second channel 32.Heat-shrink tube to be expanded passes sequentially through introduction segment, linkage section and sizing section, due to second
The diameter of passage 32 be equal to first passage 31 minimum diameter, so linkage section by heat-shrink tube to be expanded in introduction segment outside gas
Body block is lived, and is prevented it from entering sizing section, had both been discharged the pressure outside sizing section pipe, is made uniform wall thickness, is reduced inclined wall rate, reduces again
The loss of pressure in heater box 1, save the energy.
Further, the introduction segment is provided with external screw thread 34, and heater box 1 is provided with the internal thread coordinated with external screw thread 34.
