Abstract
A kind of coiled composite tube part and process units thereof.Mainly solve existing high density polyethylene (HDPE) socket pipe member cost of production high, cannot mass-produced problem by variation of ambient temperature affects greatly when producing.It is characterized in that: described high-density polyethylene layer (1) is built-in with spiral glass band (2), process units comprises glass band swelling device (9), and is provided with glass band feed mechanism (13) and shearing device (6) between glass band swelling device (9) and Wound Dies (4).This coiled composite tube adds enhancing glass on the basis of original pure plastic pipe, adds the ring stiffness of pipe fitting, and easily process, cost of production is low simultaneously.
Description
Technical field
The utility model relates to plastic tube manufacture field, specifically be a kind of coiled composite tube part and process units thereof.
Background technique
The steel band reinforced spiral ripple pipe of socket joint can have easy construction, to features such as environmental suitability are strong, there is very wide application prospect.But due to high density polyethylene (HDPE), with seasonal temperature and tube wall thickness change, shrinkage is different, and therefore the size of socket pipe member can present certain change, brings difficulty to assembled in situ.At present, the production of pipe fitting mainly contains mold injection and extrudes winding two kinds of modes, and mould production precision is high, the fine setting of carrying out size by technique, but die manufacturing cost is higher, is suitable only for the production of small-sized pipe fitting; Extrude the winding mode of production simple, can the pipe fitting of production plurality of specifications, but size cannot adjust, the shrinking law of high density polyethylene (HDPE) can only be found out by a large amount of tests, carry out the careful design of Wound Dies, but the size impact that the change of this method to ambient temperature causes cannot be eliminated.For above-mentioned reasons, high density polyethylene pipe part is caused to widely apply.
Summary of the invention
In order to overcome existing high density polyethylene (HDPE) socket pipe member cost of production high, produce time cannot mass-produced deficiency by variation of ambient temperature affects greatly, the utility model provides a kind of coiled composite tube part and process units thereof, this coiled composite tube adds enhancing glass on the basis of original pure plastic pipe, add the ring stiffness of pipe fitting, easily processing simultaneously, cost of production is low.
The technical solution of the utility model is: a kind of coiled composite tube part, comprises high-density polyethylene layer, and described high-density polyethylene layer is built-in with spiral glass band.
A kind of process units of described coiled composite tube part, comprise Wound Dies, Wound Dies outside is provided with hold down gag and extrusion neck ring mold, also comprises glass band swelling device, and is provided with glass band feed mechanism and shearing device between glass band swelling device and Wound Dies.
Described glass band feed mechanism comprises the push rolls screwdown gear be positioned at above glass band and the push rolls drive unit be positioned at below glass band.
Described push rolls screwdown gear and push rolls drive unit include running roller, and running roller outer surface is enclosed with rubber friction cover.
The utility model has following beneficial effect: owing to taking such scheme, the high-density polyethylene layer inside of coiled composite tube part is equipped with glass band, this glass band is that the polyethylene of fiberglass reinforced infiltrates band, can be combined with each other completely with high-density polyethylene layer, stop steel band and polyethylene can only form coated temporary Complex Problem by physical action on surface, while stable plumbing dimensions, add the ring stiffness of pipe fitting.This process units adds sending to of glass band and shearing device, makes the winding of glass band be tending towards automation, and structure is simple, and easy to operate, cost of production is low.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By shown in Fig. 1 to Fig. 3, a kind of coiled composite tube part, comprise high-density polyethylene layer 1, described high-density polyethylene layer 1 is built-in with spiral glass band 2, described glass band 2 is that a kind of polyethylene of fiberglass reinforced infiltrates band, can be combined with each other completely, stopped steel band and polyethylene can only form coated temporary Complex Problem by physical action on surface with high-density polyethylene layer 1, while stable plumbing dimensions, add the ring stiffness of pipe fitting.
A kind of process units of described coiled composite tube part, comprise Wound Dies 4, Wound Dies 4 outside is provided with hold down gag 3 and extrusion neck ring mold 5, glass band 2 is wound around thereon by Wound Dies 4, high density polyethylene (HDPE) is extruded to glass band 2 surface by extrusion neck ring mold 5, then by hold down gag 3 compacting.Glass band 2 is wrapped on glass band swelling device 9, and be provided with glass band feed mechanism 13 and shearing device 6 between glass band swelling device 9 and Wound Dies 4, wherein shearing device 6 is positioned at Wound Dies 4 side, glass band feed mechanism 13 is positioned at glass band swelling device 9 side.Described glass band feed mechanism 13 comprises push rolls screwdown gear 7 and push rolls drive unit 8, and wherein push rolls screwdown gear 7 is positioned at above glass band 2, and push rolls drive unit 8 is positioned at below glass band 2.Described push rolls screwdown gear 7 and push rolls drive unit 8 include running roller 12, and running roller 12 outer surface is enclosed with rubber friction cover 11, increases the frictional force on running roller 12 and glass band 2 surface.
When producing, first Wound Dies 4 is heated, after reaching uniform temperature, high density polyethylene (HDPE) is extruded from extruding membrana oralis 5, Wound Dies 4 is wound around 1 ~ 2 circle, then start glass and be wound around control system, when needing first to be between push rolls screwdown gear 7 and push rolls drive unit 8 one end of glass band when changing glass band.After control switch is opened, push rolls screwdown gear 7 compresses running roller 12 downwards under the effect of running roller pressure cylinder 10, when being pressed to a certain degree, touches position limit switch, drive motor is started working, under the rubbing action of rubber friction cover 11, drive glass band 2 to travel forward.Because rod wheel 12 has certain radian, glass band can be made to travel forward under the state of relatively straight elevator, cross shearing device 6, directly with the hot high density polyethylene (HDPE) compound be wound around.Push rolls screwdown gear 7 is provided with timer, push rolls drive unit 8 is equipped with speed probe, just can calculates now glass band by the rotating speed that measures and time and whether there is the firm compound of high density polyethylene (HDPE) in enough length and winding process.Then push rolls screwdown gear 7 lifts, and pinch roller device 3 is depressed simultaneously.Pinch roller screwdown gear is equipped with speed probe, and measure the rotating speed of pinch roller device 3, when reaching setting value, shearing device 6 starts action, the glass band that instantaneous trip is being wound around.Then high density polyethylene (HDPE) continues, to after coated 2 ~ 3 circles of glass band, to be cooled, then taken off by pipe fitting by mould emptier, can complete the production of composite pipe fitting by cooling unit to composite pipe fitting and Wound Dies.
