Abstract
The invention relates to a pipe-penetrating guiding head for a heat exchanger, which comprises a main body, wherein a guiding rod is mounted in the main body in a penetrating form; one end of the guiding rod is in threaded connection with a nut; and a rubber pipe is sleeved on one end of the main body. The pipe-penetrating guiding head for the heat exchanger has a simple structure and is convenient to mount; when the pipe-penetrating guiding head is placed into a heat exchange pipe, the tail part of the pipe-penetrating guiding head is opened by utilizing a cone at one end of the guiding rod; the rubber pipe can be compressed along an axial direction and expanded along a radial direction, a frictional force is increased and the rubber pipe is prevented from slipping off, so that the pipe-penetrating guiding head is difficult to fall off during a pipe-penetrating process; and meanwhile, the interior of the heat exchange pipe is prevented from being abraded.
Description
Technical field
The present invention relates to heat exchanger tube assembling field, relate in particular to a kind of leading head for through pipe of heat-exchanger.
Background technology
In the prior art, because the specification of heat exchanger constantly increases, cause heat exchanger inner tube bank length and weight constantly to increase, when adopting conventional method to install, because deadweight produces distortion, causing can't normal mounting in the lifting process for heat exchanger tube.Therefore can only will put into housing after tube sheet, the deflection plate assembling first, then carry out the blind operation of wearing, but because between each deflection plate, or have certain distance between deflection plate and tube sheet, and heat exchanger tube can't enter corresponding pore fast and accurately in the poling process, and there is error in assembling, cause the pore decentraction on the deflection plate, greatly improve rework rate, reduced production efficiency, affected manufacturing schedule.
Summary of the invention
The applicant provides a kind of leading head for through pipe of heat-exchanger simple in structure, easy for installation for above-mentioned existing shortcoming, has fast and accurately advantage of poling.
The technical solution adopted in the present invention is as follows:
A kind of leading head for through pipe of heat-exchanger comprises main body, and the installation guide rod is run through in the inside of main body, and an end of guide rod is connected with nut thread, also is set with rubber tube in an end of main body.
Its further technical scheme is:
One end of described main body is cone, and the other end has " ten " font groove;
One end of described guide rod is cone.
Beneficial effect of the present invention is as follows:
The present invention is placed heat exchanger tube, utilize the cone of guide rod one end that afterbody of the present invention is strutted, but because the rubber tube axial compression, be radially expanded, increasing friction force prevents slippage, make its difficult drop-off in the poling process, can prevent the inner appearance wearing and tearing of heat exchanger tube simultaneously.The cone of knife bar one end has reduced the contact area between heat exchanger tube and tube sheet, the baffle plate, has improved the poling accuracy rate, has reduced work difficulty.

Fig. 3 is the structural representation of guide rod of the present invention.
Fig. 4 is structural representation of the present invention.
Fig. 5 is that the present invention is at the structural representation of the course of work.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 4, the present invention includes main body 2, an end of main body 2 is cone, and the other end has " ten " font groove.As shown in Figure 2, run through installation guide rod 4 in the inside of main body 2, as shown in Figure 3, an end of guide rod 4 is cone.Such as Fig. 1, shown in Figure 4, an end of guide rod 4 is threaded with nut 1, also is set with rubber tube 3 in an end of main body 2.
Specific works process of the present invention is as follows:
As shown in Figure 5, the present invention who assembles is inserted in the heat exchanger tube 5, the conical end of main body 2 and heat exchanger tube 5 one ends fit tightly, this moment, moving leader 4 strutted afterbody of the present invention by guide rod 4, but the rubber tube axial compression, be radially expanded, increasing friction force prevents slippage.After strutting, rubber tube 3 props up the internal face of heat exchanger tube 5.Because an end of guide rod 1 has screw thread, and nut 1 is tightened, and prevents that guide rod 4 from moving.Nut 1 has also effectively avoided guide rod 4 to slip into the situation of heat exchanger tube 5 inside.
In the poling process, the cone of guide rod 4 of the present invention contacts first the hole body edge, then slowly advances along the conical surface to enter hole body, and heat exchanger tube is slipped in the pore, bore a hole complete after, unclamp nut 1, knock guide rod 4 and extract the present invention.
The present invention is placed heat exchanger tube, utilize the cone of guide rod one end that afterbody of the present invention is strutted, but because the rubber tube axial compression, be radially expanded, increasing friction force prevents slippage, make its difficult drop-off in the poling process, can prevent the inner appearance wearing and tearing of heat exchanger tube simultaneously.The cone of knife bar one end has reduced the contact area between heat exchanger tube and tube sheet, the baffle plate, has improved the poling accuracy rate, has reduced work difficulty.
More than describing is explanation of the invention, is not that limited range of the present invention is referring to claim to the restriction of invention, and in the situation of basic structure of the present invention, the present invention can do any type of modification.
