Steel-plastics composite pipe suitable for tube inner diameter range 50mm-600mm, belongs to steel skeleton composite production line component assembly manufacturing field.
Background technology
CN 1281399C, title " a kind of manufacturing method of steel skeleton-plastic composite pipe ", including using plug-in weft disk
Mode provide weft steel wire to weldering net forming machine, weldering net forming machine will be from warp dispenser using Fuzzy Resistance welding
Netted steel skeleton is formed together with warp steel wire and weft steel wire weld, netted steel skeleton is continuously drawn through compounding machine
Head, composite machine head surround netted steel skeleton and receive that plastic extruder continuously supplies from side to composite machine head and is molten from the outside
The thermoplastic melted will be compounded to form pipe, traction tube in composite machine head inside and outside the thermoplastic of melting and steel skeleton
Base forms multiple tube by cooling device.Its shortcoming：It only should be mentioned that warp dispenser, but match without open warp
It send the specific technical solution of device and forms the technological means of technical solution, and well known warp adapting device is generally work
Manual dispenser is filled, not only work efficiency is low, and labor intensity is big, and formed precision is poor；Abrasion resistance properties are poor, it is impossible to right well
Steel skeleton positions, and easily goes out in production with inclined phenomenon is netted, causes network framework exposed, tubing is scrapped.Resuming production must obtain more
Part is changed, leads to cost increase.Efficiency is low.
Invention content
Purpose of design：The shortcoming in background technology is avoided, designs sizing mill in a kind of circumferential warp conveying and tubing
Structure, steel skeleton welding and internal shaping problem look for main-shaft core by front and back end locating ring, and warp is by threading wire installation, warp
Weft soldering wiring electric installation, tubing internal shaping device, interior sizing and interior cooling device, ultimately form in a kind of plastic pipe
Containing steel skeleton, there is smooth inner wall steel-plastics composite pipe.
Designing scheme：The present invention relates to one kind needed for steel skeleton net forming in a kind of steel skeleton net compound plastic pipe
" sizing mechanism in circumferential warp conveying and tubing ", purpose ensures that warp is circumferentially disposed uniform and keeps warp and tubing axle center
Parallel, weld strength is high, steel skeleton size is suitable and steel skeleton net position is relatively fixed in the pipe wall；Make resistance to rotten plastics complete
Wrap up steel skeleton simultaneously, tubing in actual use steel skeleton receive by main pressure, in production circumferential surrounding send plastics by
It squeezes out outside to inside and is formed simultaneously the smooth pipe of inner surface.The present invention is by rear alignment coil apparatus, threads wire installation, and front end is fixed
Position coil apparatus, latitude and longitude soldering wiring electric installation, tubing internal shaping device, interior sizing and the most of group of interior cooling device six
Into.

Line loop is to prevent warp long term wear rear alignment circle and damage, while prevent card line phenomenon.
2nd, wire installation is threaded：Penetration pipe both ends are fixed on the locating ring of front and back end, while tube outer wall abuts mandrel phase
Mutually against uniformly surrounding one week, tile encircles penetration pipe one week, is the two of the technical characteristic of the present invention.The purpose done so exists
In：Rear and front end locating ring distance is longer to facilitate wire guide to dock.Tile hug penetration pipe be prevent penetration pipe itself elongated and
Natural torsion phenomenon occurs
3rd, front end positioning coil apparatus：Front end locating ring and separated time slot are fixed on mandrel, and case encircles separated time slot, are of the invention
The three of technical characteristic, the purpose done so are：There is outlet hole with separated time slot in the locating ring of front end docks effect, while latitude very well
Line will not run out of separated time slot.
4th, latitude and longitude soldering wiring electric installation：Copper sheathing fixes skewback before and after slot electrode, and plate washer is all installed on mandrel, and zero
Part end face abuts, and slot electrode is mounted on each groove center alignment in copper sheathing peripheral groove, is the four of the technical characteristic of the present invention, does so
Purpose be：It is more demanding to the cooperation of each part and position relationship because warp generates welding process when passing through slot electrode, energy
Fixed slot electrode well, ensure that electric conductivity.
5th, tubing internal shaping device：Only expect seat, interior material feeding sleeve, positive wire stitcher, transition sleeve is all on mandrel, each part
End face abuts, and is the five of the technical characteristic of the present invention, the purpose done so is：Welding forming steel skeleton net needs to keep
Shape during welding must not have metaboly；Internal shaping region needs certain storing to ensure ecto-entad plastics shape pipe forward simultaneously
Base, it is impossible to run material backward.
6th, interior sizing and interior cooling device：Flange is mounted on mandrel, and spiral cooling jacket is fixed with flange, jacket of internal diameter determined
Inner circle is sleeved in spiral cooling jacket outer circle, and both ends sealing is the six of the technical characteristic of the present invention；The purpose done so is：
Make pipe material inner wall cooling uniform, leak must not seal at both ends, is formed simultaneously smooth even pipe material inner wall.
Technical solution 1：Sizing mechanism in a kind of circumferential direction warp conveying and tubing, by rear alignment coil apparatus, threading conducting wire
Device, front end positioning coil apparatus, latitude and longitude soldering wiring electric installation, tubing internal shaping device and interior sizing and interior cooling device
It forms；Rear alignment coil apparatus covers core back-end, and front end positioning coil apparatus is sleeved in the middle part of mandrel, and threading wire installation is located at rear end
It positions between coil apparatus and front end positioning coil apparatus, latitude and longitude soldering wiring electric installation is located at mandrel forepart and determines by front end
Position coil apparatus, tubing internal shaping device are located at latitude and longitude soldering wiring electric installation side, and interior sizing and cooling device are located at pipe
Into opening apparatus side in material.
Technical solution 2：Sizing mechanism method of work in a kind of circumferential direction warp conveying and tubing, warp steel wire is by Qian Dao mechanisms
It unreels and is released in station, enter penetration pipe into rear alignment circle middle ring guide string holes and out sequentially entered point by front end locating ring
Wire casing, slot electrode, the peripheral mechanism of receiving send weft and are welded into steel skeleton net, and steel skeleton net is through only material seat to positive wire stitcher holding steel
Then skeleton relative position in the pipe wall forms pipe material inner wall pipe through jacket of internal diameter determined, finally receive haulage gear load for leading
Gravitation constantly forward provide needed for steel skeleton net.
For the present invention compared with background technology, one is to ensure that warp steel wire circumferential direction is evenly arranged；Two are to ensure that steel skeleton welds
Forming process needs intensity and good conductivity；Third, during internal shaping steel skeleton steel wire will not sideslip, plastics will not run material backward；
Fourth, smooth even inner wall can be formed；Fifth, it is easy to operate, it is efficient.
