Condition, increases the quantity of roller 52, repeats one by one herein.
Cavity volume 20 also has the second opening 28, and the second opening 28 is arranged on rubber sheath 12 of the harness 10 in cavity volume 20
Harness passage 14 after progress path on, it is dynamic in next step to carry out further to advance to allow harness 10 to be pierced by cavity volume 20
Make, such as penetrate another rubber sheath threader being set up in parallel with the rubber sheath threader 200 in Fig. 3 (in figure not
Show), another rubber sheath to be threaded then placed in the rubber sheath threader.
As shown in Figures 3 and 4, rubber sheath threading device 200 further includes air flue 30, and air flue 30 is connected with cavity volume 20, for
Air-flow 40 is filled with cavity volume 20.Air flue 30 includes the first air flue 32 and the second air flue 34, and the first air flue 32 and the second air flue 34 are distinguished
The first module 22 and the second module 24 are arranged at, and the first air flue 32 and 34 respective one end of the second air flue are connected with cavity volume 20,
So that air-flow 40 is filled with cavity volume 20.Wherein, the first air flue 32 and 34 respective one end 321 connected with cavity volume 20 of the second air flue and
341 are set towards the harness passage 14 of the rubber sheath 12 in cavity volume 20, so that entering the air-flow 40 of cavity volume 20 from air flue 30
It can be filled with harness passage 14, so that rubber sheath 12 is expanded along perpendicular to the direction of harness passage 14, then make harness
The internal diameter r of passage 14 becomes larger, until the outside diameter R more than harness 10.The inner wall 201 of cavity volume 20 and the rubber sheath 12 in cavity volume 20
Harness passage 14 outer surface 141 between be equipped with gap 90, so that rubber sheath 12 is filled with harness passage 14 in air-flow 40
When, it can leave along the space expanded perpendicular to the direction of harness passage 14.
As shown in figure 5, rubber sheath threading device 200 further includes sealing block 60, sealing block 60 is used for the second opening 28
Sealing, and the second opening 28 can be opened after mobile relative to 28 movement of the second opening.
The method threaded using above-mentioned rubber sheath threading device to rubber sheath is included：
Cavity volume 20 is provided, rubber sheath 12 to be threaded is positioned in cavity volume 20；
Air-flow 40 is provided and is filled with cavity volume 20 from air flue 30, is pressed with forming an expansion in the harness passage 14 of rubber sheath 12
Strong P, so that rubber sheath 12 is expanded outwardly along perpendicular to the direction of harness passage.Wherein, P=nRT/V, n are gas flow, and R is
Gas constant, T are gas temperature, and V is cavity volume space.Further, n=airflow inlets flow-air stream outlet flow.
In the case that the architectural features such as shape, size in rubber sheath 12 are identical, the hardness of rubber sheath 12 is bigger, its
Required expansion pressure P is also bigger, otherwise smaller.For example, utility model people is learnt by experiment, expansion hardness is 56HA's
Expansion pressure needed for rubber sheath is 0.7MPa.
For the present embodiment, R, T, V are constant, and the variable for influencing to expand pressure P is only n.It is in the following, hard to expand
Spend exemplified by the rubber sheath 12 for 56HA, the air-flow 40 needed for different phase advanced to how to determine harness 10 enters cavity volume 20
Flow illustrate：
Harness 10 penetrates cavity volume 20 from the first opening 26, does not penetrate harness passage 14.Since harness 10 is opened into cavity volume 20
Begin, harness 10 plays the role of closure to the first opening 26, after air-flow 40 enters cavity volume 20, is only capable of opening from harness 10 and first
It is lost in gap between mouth 26, since the gap between the opening of harness 10 and first 26 is very small, it is lost in from the gap
Air-flow can be ignored.That is, gas vent flow is almost nil.Therefore, when the airflow inlet flow of air-flow 40
During >=PV/RT, you can expand rubber sheath 12 so that harness 10 runs through.
Harness 10 is penetrated in the harness passage 14 of expansion, not completely through harness passage 14 (as shown in Figure 5).Harness 10 is right
The closure of first opening 26 is with last stage, and therefore, airflow inlet flow >=PV/RT can continue to the expansion of rubber sheath 12
, harness 10 can continue on.
Harness passage 14 (as shown in Figure 6) of the harness 10 completely through expansion.Closure of the harness 10 to the first opening 26 is same
On last stage, therefore, airflow inlet flow >=PV/RT can continue to the expansion of rubber sheath 12, and harness 10 can continue on.
The above-mentioned stage, i.e., before harness 10 is moved to and closes on the second opening 28, in order to avoid entering the gas in cavity volume 20
Stream 40 is lost in from the second opening 28, and sealing block 60 is in the position of 28 sealing of the second opening all the time.
Harness 10, which marches to, closes on the second opening 28.If harness 10 needs further to advance to carry out next step action, example
Another rubber sheath threader (not shown) being set up in parallel with the rubber sheath threader 200 in Fig. 3 is such as penetrated,
Then run through another rubber sheath to be threaded for placing in the rubber sheath threader, then move sealing block 60 to open the
Two openings 28.The stage, closure of the harness 10 to the first opening 26 is same on last stage, and similarly, it is pierced by from the second opening 28
Closure also played to the second opening 28 the effect (as shown in Figure 7) of harness 10, after the entrance cavity volume 20 of air-flow 40, be only capable of from line
It is lost in the gap 80 between gap and the opening of harness 10 and second 28 between the opening of beam 10 and first 26, due to harness
10 and first opening 26 between gap and harness 10 and second opening 28 between gap 80 it is very small, therefore, from these
The air-flow that gap is lost in can be ignored.That is, gas vent flow is almost nil.Therefore, airflow inlet flow >=
PV/RT can continue to rubber sheath 12 and expand, and harness 10 can continue on.
By above-mentioned analysis, using the utility model implement the rubber sheath threading device that provides to rubber sheath into
Row threading, it is only necessary to keep the stability of air-flow 40, you can ensure the stability of the expansion air pressure P in harness passage 14, so that
The expansion stability of rubber sheath 12 is improved.At the same time, it is only necessary to which the air flow rate for entering cavity volume is controlled by, you can realize
Adjusting to the expanded dimension of rubber sheath, simplifies technological process.
The rubber sheath threading device that the utility model embodiment provides, expands rubber sheath using air pressure, phase
Expand apparatus compared with manual operation, more efficient, the stress of rubber sheath evenly, expands stability higher, can avoid apparatus
The expansion action directly contacted with rubber sheath, so as to avoid the infringement to rubber sheath, it is ensured that the performance of rubber sheath.
Embodiment in the utility model is only used for illustrating the utility model, does not form to right
Limitation, other substantially equivalent replacements that those skilled in that art are contemplated that, in scope of protection of the utility model
It is interior.
