Fixed, efficiently solve and former mould in muscle pipe production process because of the bonding of material and the major defect problem of certain material can only be selected,
Overcome prior art restriction on material selects.
Embodiment 2
As Fig. 2, Fig. 3 and Fig. 4 jointly shown in, this utility model additionally provides the spiral of a kind of improvement and moulds muscle pipe and produce dress
Putting, its structure is substantially the same manner as Example 1, but on the basis of embodiment 1, continues to have done following many improvement:
In embodiment 1, although mould the body after muscle and molding and the most jointly extrude, but there will be because material itself is asked
Topic, is sometimes difficult to so that body is firmly combined with moulding muscle surface, still can produce and mould muscle and body separating phenomenon during use,
Thus cause moulding muscle tube failure.
In order to solve above-mentioned technical problem, utility model people of the present utility model has done further investigation and lot of experiments, from
And carried out following concrete improvement, overcome above-mentioned defect, achieve the most excellent technique effect.
Being provided with in guide road 6 for the notcher 11 of fluting on body, notcher 11 has one and stretches to body shaping cover 3
The fluting portion 1101 of inner chamber and the communicating passage 1103 in inner chamber and guide road 6 of communicating pipe body-shaping set 3, carried at body
Cheng Zhong, first tube surfaces is processed a groove by fluting portion 1101, and material enters in groove by communicating passage 1103 simultaneously,
Along with the rotation of rotary sleeve 2, form spiral at tube surfaces and mould muscle, but so formed mould muscle and traditional handicraft and enforcement
The muscle of moulding formed in example 1 compares, and moulds the combination of muscle and body not only on its surface, but embeds in body, moulds making of muscle pipe
It is greatly improved by performance, and moulds muscle disengaging very difficult with body, substantially prolongs the service life moulding muscle pipe.
So that material is entered the inner chamber of body shaping cover 3 smoothly by guide road 6, prevent material heap on notcher 11
Long-pending, notcher 11 is provided with burden-guiding cone 1102, and burden-guiding cone 1102 is positioned at guide road 6, the bottom surface of burden-guiding cone 1102 and notcher
11 offset, material can enter communicating passage 1103 smoothly through the shunting of burden-guiding cone 1102, it is to avoid mould in muscle forming process
Produce tomography or bubble.
Wherein, notcher 11 is fixedly installed on end cap 10, can be convenient for changing different notchers 11, with satisfied difference
The muscle pipe of moulding of specification produces.Rotary sleeve 2 is provided with pin-and-hole, and pin-and-hole is arranged at the second end opening position in guide road 6, notcher 11
Being provided with alignment pin 1104, alignment pin 1104 is suitable with pin-and-hole so that notcher 11 forms support in guide road 6, it is to avoid
Notcher 11 is deformed by material impact so that mould muscle spiral on body smooth and smooth, and product stability is high, further
Improve the product quality moulding muscle pipe.
It addition, in actual production process, there is also a difficult problem, it is simply that when mould muscle pipe only need a certain bar therein or
Person guide road 6, without the guide road 6 that other are unnecessary, namely moulds muscle pipe requirement and moulds muscle quantity less than guide road 6
During quantity, it is necessary to change other set device, add use cost.
For this technical barrier, utility model people continues through further investigation, thus overcomes this defect, the most such as
Under: as it is shown in figure 5, arrange the baffle plate 12 in closure guide road 6 on end cap 10, this baffle plate 12 has suitable with tubular form
Offer correction groove 1001 on surface, and baffle plate 12, baffle plate 12 is similarly provided at the suitable alignment pin of pin-and-hole 1104, can
To utilize original pin-and-hole, and this structure can also improve the intensity of baffle plate 12.
In moulding muscle pipe forming process, utility model people finds, after guide road 6 uses baffle plate 12 closure, and moulding of molding
Muscle tube-surface can produce undulatory defect.For this defect, nitrogen can be passed through in the guide road 6 after closure so that guide
Forming malleation in road 6, its pressure need not be too high, slightly above normal atmosphere, usually the standard atmosphere of 1.1-1.2 times
Pressure, now produce to mould muscle tube-surface smooth, further increase the product quality moulding muscle pipe.
As it has been described above, this utility model provides a kind of spiral moulds muscle pipe process units, described device is by unique knot
Structure design and the improvement of many specific structural details, such that it is able to obtain many useful technique effects, moulding muscle Manifold technology neck
Territory has a good application prospect and industrial production potential.
The purposes that should be appreciated that these embodiments is merely to illustrate this utility model and is not intended to limit of the present utility model
Protection domain.Additionally, it will also be appreciated that after having read technology contents of the present utility model, those skilled in the art can be right
This utility model makees various change, amendment and/or modification, and all these equivalent form of value falls within right appended by the application equally and wants
Within seeking the protection domain that book is limited.
