Further, a dog hole is offered on the outside of the middle section part of the guide head.
Further, the cross section of the dog hole is circle, and the diameter of round dog hole and the diameter ratio in cylinder middle section are
1:10~20, the depth of round dog hole are the 1/15~1/10 of the diameter in cylinder middle section.The size of dog hole will meet hook simultaneously
It exerts a force during insertion, and the excessive volume in cylinder middle section cannot be occupied, influence its whole shape and stability, and beautiful
Property.
Further, the length ratio of the taper leading portion, cylinder middle section and cylinder back segment three is 1:1:3.Guarantee as far as possible
Cylinder back segment in insertion heat exchanger tube is sufficiently connect with it, is unlikely to pitch, be influenced the course；In the taper leading portion of front, cylinder
For section on the basis of meeting guide function, operation is convenient in shortening length, saving space as far as possible.
Further, the angle of the anti-dropout clamping steel wire bending is 30 ° -120 °.Anti-dropout clamping steel wire can be curved
Various angles are presented in folding, flexibly stretch in heat exchanger tube, while playing snap action.
Further, one section between the two neighboring inflection point of anti-dropout clamping steel wire is on the vertical plane of central axes
Projection width is 1~1.2 times of the internal diameter of heat exchanger tube.The projection width of anti-dropout clamping steel wire, which is equal to or is slightly more than, to change
The internal diameter of heat pipe also guarantees to realize and its clamping so that it is fully stuck in heat exchanger tube even if there is the case where steel wire bent
The effect of；But guarantees that clamping force is unlikely to excessive again simultaneously, after use, taken from heat exchanger tube 3 with hook holder guided tooling
When getting off, it will not block.
The utility model has the advantages that a kind of guided tooling of heat exchanger tube poling of the utility model has following compared with prior art
Advantage: using this tooling, and centering is easy during poling, and heat exchanger tube is not easy to block, and can greatly improve poling speed, improves work
Make efficiency.
Detailed description of the invention
Fig. 1 is the guided tooling structural schematic diagram of the utility model；
Fig. 2 is conventional poling schematic diagram；
Fig. 3 is the utility model for poling overall structure diagram.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of guided tooling of heat exchanger tube poling, is made of, anticreep guide head 4, anti-dropout clamping steel wire 5
Fall the tail end face that clamping steel wire 5 is welded in guide head 4.
The front section of guide head 4 is cone, is taper leading portion；Middle section part is cylindrical, is cylinder middle section, outer diameter
It is identical as the outer diameter of heat exchanger tube 3；Tail portion is cylindrical, is cylinder back segment, and outer diameter is 0.1~0.5mm smaller than the internal diameter of heat exchanger tube 3,
Preferably 0.1mm, to guarantee that tail portion can be inserted into heat exchanger tube 3.The length ratio of taper leading portion, cylinder middle section and cylinder back segment three
For 1:1:3.
The cylinder middle portion of guide head 4 is separately equipped with a dog hole 6, uses hook holder guided tooling from heat exchange after being used to poling
