Description
Technical field
The utility model is related to tubing, and in particular to a kind of wear-resisting calibration sleeve of segmented.
Background technology
At present, plastic pipe production uses vacuum sizing box sizing, and production PVC typically uses the side of external diameter sizing
Method, its calibration sleeve material is generally using copper alloys such as tin bronze or brass, and structure uses the calibration sleeve with pre-cooler.
Due to copper softer, it is easy to that abrasion can be produced because occurring friction with tubing during calibration sleeve use,
Cause the surface irregularity of plastic pipe, product quality is substantially reduced, so that calibration sleeve must not be changed infrequently, cause to be produced into
This raising.The usual solution to this problem is to change the material of calibration sleeve into stainless steel by copper alloy in the prior art.
Because the hardness of stainless steel is higher than copper alloy, copper alloy is substantially better than in terms of wearability, along with stainless steel is closed than copper
Golden cheaper, can so substantially reduce the replacement frequency of calibration sleeve, reduce production cost；But thus produce again
The problem of new, because the heat conductivility of stainless steel is substantially not so good as copper alloy, if whole calibration sleeve all changes stainless steel into, produce
Pipe workpiece quality out can equally be deteriorated.This problem exists always in the prior art, and those skilled in the art are often trapped in
Carried out in different materials selection face a difficult choice among.
Utility model content
For the deficiency in the presence of prior art, the utility model proposes a kind of production that both can guarantee that plastic pipe
Quality, and abrasion can be reduced, the wear-resisting calibration sleeve of segmented of production cost is reduced.
A kind of wear-resisting calibration sleeve of segmented, including tubular body, the side wall of body are provided with some inlet openings, and it is special
Levy and be：The body is divided into before and after internal diameter identical two sections, and leading portion body is detachably connected whole into one with back segment body
Body, the leading portion body is internally formed coaxial cylindrical cavity with back segment body；The leading portion body is made up of copper alloy, institute
Back segment body is stated to be made of stainless steel；The height of the back segment body accounts for the 15%~40% of whole body height.
As optimization, the height of the back segment body accounts for the 20%~30% of whole body height.
Further, the leading portion body is connected with back segment body by screw thread or flange.
Further, the back segment body can be arranged in pairs or groups and be connected with a variety of various sizes of leading portion set body phases.
Further, the inlet opening is slit pore or small sircle hole.
Compared with prior art, the utility model has the following advantages：
1st, the utility model employs the segmented calibration sleeve of leading portion copper back segment stainless steel, has both maintained leading for leading portion body
It is hot, it is ensured that the quality of production of tubing, the wearability of back segment body is strengthened again, is reduced the abrasion of calibration sleeve, is reduced
The cost of replacing；
2nd, the utility model uses segmentation structure, the consistent wall of specification that same back segment body can be used for various material
The production for the plastic pipe that thickness differs, only need to change various sizes of leading portion body, back segment body can with general, such one
Carry out calibration sleeve without replacing completely, reduce production cost.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
In figure, 1- leading portion bodies, 2- back segment bodies, 3- inlet openings, 4- connecting portions.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment：
A kind of wear-resisting calibration sleeve of segmented, as shown in figure 1, including tubular body, the side wall of body is provided with some
Inlet opening 3, the body is divided into before and after internal diameter identical two sections, with one section of close mouth mold for leading portion, and another section is back segment, preceding
The section back segment body 2 of body 1 is detachably connected into an entirety, and the leading portion body 1 is internally formed coaxial with back segment body 2
Cylindrical cavity；The leading portion body 1 is made up of copper alloy, and the back segment body 2 is made of stainless steel；The back segment body 2
Height account for the 15%~40% of whole body height.
Inventor has found that in use, the abrasion condition of different parts is simultaneously differed calibration sleeve in production practices,
It weares and teares the calibration sleeve second half section mostly occurred and passed through after tubing is hardened through cooling.In general, close to calibration sleeve afterbody 1/3
The position abrasion of left and right starts to become obvious, weares and teares more serious closer to afterbody.In this programme, due to the more appearance of back segment body
Easily it is worn, and the requirement to thermal conductivity does not have leading portion body high, therefore back segment body uses stainless steel.If after stainless steel
The height of section body is too small, then does not have obvious abrasion resistant effect；If the height of back segment body is excessive, influence whether that tubing is cold
But effect.So, by using appropriate height stainless steel back segment body segmented calibration sleeve, both maintain leading portion
The thermal conductivity of body, it is ensured that the quality of production of tubing, strengthens the wearability of back segment body again, reduces the mill of calibration sleeve
Damage, reduce the cost of replacing.Copper alloy refers to the Cu alloy material that brass, tin bronze etc. can be used for manufacture calibration sleeve herein.
Make further optimization to such scheme, the height of the back segment body 2 accounts for the 20%~30% of whole body height.
Consider in terms of the quality of production, wearability and production cost, effect is used when back segment body height is in the proportion
Fruit is preferably.
The leading portion body 1 is connected through a screw thread with back segment body 2.For example in Fig. 1, close to leading portion on back segment body 2
One end of body 1 is provided with connecting portion 4, and the inner side of connecting portion 4, which is provided with internal thread, the leading portion body 1, corresponds to connection
The position in portion 4 is provided with external screw thread.In addition, front and rear sections body can also be connected by means such as flanges, be allowed as long as can play
Front and rear sections body can align exactly when connecting, and will not occur dislocation, bias.
The back segment body 2 mutually can arrange in pairs or groups and be connected with a variety of various sizes of leading portion bodies 1.Segmentation structure is determined
Footpath covers the production that can be used for the various material such as plastic pipe that the consistent wall thickness of PVC, PE, PPR equal-specification differs, and only needs to change
Various sizes of leading portion body；A kind of back segment body can correspond to a kind of specification, for the unlike material pipe of same specification
For the manufacture of material, back segment body can be with general, and so calibration sleeve reduces production cost without replacing completely.
The inlet opening 3 is slit pore.In addition or small sircle hole, if can reach make pipe outer surface with
Lubricating water film is formed between calibration sleeve inner surface.
Preferred embodiment of the present utility model is the foregoing is only, on protection domain of the present utility model is not limited in
Embodiment is stated, every technical scheme for belonging to the utility model principle belongs to protection domain of the present utility model.For this
For the technical staff in field, some improvement carried out on the premise of principle of the present utility model is not departed from, these improvement
It should be regarded as protection domain of the present utility model.
