Description
Technical field
The utility model belongs to mold in shaper technical field more particularly to a kind of sizing of nylon tube.
Background technology
In nylon tube processing technique field, it is sometimes desirable to which, by nylon tube bend fixing, nylon tube sizing at present, which uses, first will
Straight nylon tube bending, then shapes in a mold again.When nylon tube is bent, it be easy to cause pipeline in bending part and shrivels, not only
It is beautiful to influence product, but also oily sectional area can be caused to become smaller, increases the flow resistance in oil circuit.In order to avoid above-mentioned phenomenon
Generation, sizing is repeatedly vulcanized using multiple bending, repeatedly cools down and heats vulcanization, not only need more multi-mould in this way, cause
The waste of the energy, but also production efficiency can be reduced, increase cost of goods manufactured.
Utility model content
The technical problems to be solved in the utility model be just to provide one kind can effectively avoid bending part shrivel, manufactured product
Appearance looks elegant, oil stream dynamic resistance are small, energy saving, production efficiency is high, mold in the simple nylon tube sizing of working procedure.
In order to solve the above technical problems, the technical solution adopted in the utility model is：Including helical spring, in the spiral
The sizing internal thread that spring inner is provided with has the first draw ring in the helical spring end set, is set on the sizing internal thread
It is equipped with the first bail being fixedly connected with first draw ring.
Its additional technical feature is：
The helical spring is one, the other end of the helical spring is provided with the second draw ring, in the sizing
The second bail being fixedly connected with second draw ring is provided on internal thread；
The helical spring is two, which is serially connected.
Mold compared with prior art, has the following advantages in nylon tube sizing provided by the utility model：First, by
In including helical spring, in the sizing internal thread that the helical spring is internally provided with, have in the helical spring end set
One draw ring is provided with the first bail for being fixedly connected with first draw ring on the sizing internal thread, will sizing internal thread and
Helical spring is inserted into nylon tube, and the internal diameter for making spring outside coil diameter and nylon tube is of substantially equal, and during bending, helical spring is to Buddhist nun
Imperial pipe plays certain supporting role, and it is deflated in bending part to avoid nylon tube, and sizing internal thread is fixed after nylon tube bending using iron wire
Type internal thread certain styling since self-characteristic plays avoids nylon tube recovery, after vulcanization is shaped, passes through internal thread of shaping
Helical spring is pulled out, more convenient to use, manufactured nylon tube oil hinders small, good appearance, not only increases production efficiency, drops
Low production cost, and saved the energy, the helical spring and sizing internal thread of pull-out can be used for multiple times after stretching；Second,
Since the helical spring is one, the other end of the helical spring is provided with the second draw ring, in the sizing internal thread
On be provided with the second bail being fixedly connected with second draw ring, the first draw ring and the second draw ring when drawing helical spring
Helical spring is acted on simultaneously, avoids helical spring damage, extends the service life of helical spring；And it is being inserted into spiral
It is more convenient during spring；Third, since the helical spring is two, which is serially connected, when
When needing the nylon length of tube of bending longer, when being more than 1 meter such as length, if using a helical spring, in nylon tube bending
Rear coil springs pull out resistance it is larger, be easy to cause helical spring draw it is bad, the service life of helical spring is shortened, using two
Helical spring is sleeved on sizing internal thread, and the opposite side of two helical springs is held out against, in bending, two springs and a spring
Role is identical, and after sulfidization molding, two helical springs are pulled out in both directions respectively, and it is small to pull out resistance.

Specific embodiment
It is former to the structure and use of mold in the sizing of the utility model nylon tube with reference to the accompanying drawings and detailed description
Reason is described in further details.
As depicted in figs. 1 and 2, mold includes helical spring 1 in the sizing of the utility model nylon tube, in helical spring 1
The sizing internal thread 2 that portion is provided with has the first draw ring 3 in 1 end set of helical spring, is provided with and first on sizing internal thread 2
The first bail 4 that draw ring 3 is fixedly connected.As shown in Figure 5 and Figure 6, sizing internal thread 2 and helical spring 1 are inserted into nylon tube 5
In, make 1 outer diameter of helical spring and the internal diameter of nylon tube 5 of substantially equal, during bending, helical spring 1 plays certain branch to nylon tube 5
Support acts on, and it is deflated in bending part to avoid nylon tube 5, sizing internal thread 2 using iron wire, shape after 5 bending of nylon tube internal thread 2 due to
Self-characteristic plays certain styling, avoids nylon tube recovery, after vulcanization is shaped, by internal thread 2 of shaping by spiral bullet
Spring pulls out, more convenient to use, and manufactured nylon tube oil resistance is small, and good appearance not only increases production efficiency, reduces production
Cost, and the energy has been saved, the helical spring of pull-out can be used for multiple times after being stretched with internal thread of shaping.
As shown in figure 3, helical spring is one, the other end of helical spring 1 is provided with the second draw ring 6, in sizing
The second bail 7 being fixedly connected with the second draw ring 6 is provided on silk 2, first draw ring 3 and second when drawing helical spring 1
Draw ring 6 acts on helical spring 1 simultaneously, avoids helical spring 1 and damages, extends the service life of helical spring；And
It is inserted into more convenient during helical spring.
As shown in figure 4, helical spring 1 is two, this two helical springs 1 are serially connected, when needing bending
When nylon length of tube is longer, when being more than 1 meter such as length, if using a helical spring, in nylon tube bending rear coil springs
Pull out resistance it is larger, be easy to cause helical spring draw it is bad, the service life of helical spring is shortened, using as shown in Figure 4 two
Root helical spring is sleeved on sizing internal thread, and the opposite side of two helical springs 1 is held out against, in bending, two springs and one
Spring role is identical, and after sulfidization molding, two helical springs are pulled out in both directions respectively, and it is small to pull out resistance.
The scope of protection of the utility model is not limited solely to above-described embodiment, as long as structure and the utility model nylon tube
Mould structure is same or similar in sizing, just falls the range protected in the utility model.
