Background technology
Existing thermosetting machine barrel is mostly that, using hot jacket interference fit, centre plus dividing plate, this technology outer liner is non-disconnectable
Unload, and sealing effectiveness is bad, easily causes oil leak, inside can not be cleaned completely, when there is oil leakage phenomenon, can only entirely bushing weldering
Extremely, manufacturability extreme difference；Due to there was only a dividing plate in the middle of simultaneously, fluid mobility is bad, and temperature control is poor；In addition, screw rod is adopted
38CrMoAlA materials are used, in processing thermosetting plastics, this screw rod is not wear-resistant, and some producers use high abrasion nut stem material instead,
But its cost is extremely high.
As can be seen here, such screw mechanism need to improve, to increase its every performance, reduces cost, to meet life
The need for product.
The content of the invention
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of dismantled and assembled wear-resistant thermosetting machine
Barrel screw mechanism, its processing, convenient disassembly, anti-wear performance is good, good sealing effect, easy cleaning, low cost.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of dismantled and assembled wear-resistant thermosetting machine barrel screw mechanism, it includes screw rod, the barrel outside screw rod and sets
In the nozzle of screw tip, the nozzle head is provided with spray orifice；Two sections of bushings being set up in parallel, institute are additionally provided with outside the barrel
State between barrel and bushing to be detachably connected；The outside of the nozzle is provided with nozzle and cap, and the nozzle and cap sleeve are located at expects
The outside of cylinder one end and between barrel to be threadedly coupled；The outer surface of the barrel is provided with helical groove, the barrel and two
Refractory seals part is equipped between section bushing.
Preferred scheme, for holding screw is connected between the barrel and bushing, preferably interior hexagonal holding screw.
Further preferred scheme, the helical groove is two sections and is set up in parallel that two sections of bushings are respectively arranged on two
The outside of section helical groove.
Scheme still more preferably, the outside of the barrel offers four sealed grooves, the refractory seals part
In four sealed grooves, and four sealed grooves are respectively arranged on two sections of two ends of bushing.
The refractory seals part is fluorine rubber seal element.
Wear resistant spray nozzle borehole jack is provided with inside the spray orifice, the nozzle borehole jack is wolfram steel set.
The screw rod end face homogenizing zone heap is welded with high-wear-resistant alloy.
By using above technical scheme, a kind of dismantled and assembled wear-resistant thermosetting machine barrel screw mechanism of the utility model with it is existing
There is technology to compare, its advantage is：
1st, mechanism's barrel outside car has two sections of helical grooves, is beneficial to fluid and flows through, and area is flowed through greatly, to whole section of barrel
Temperature control it is more accurate.
2nd, the outer car of barrel has four sections of seal grooves, and mounted inside has resistant to elevated temperatures viton seal ring, and sealing ring is unlikely to deform,
Good sealing effect, not easy oil leakage.
3rd, screw rod end face homogenizing zone built-up welding high abrasion dual alloy, improves the wearability of screw rod, while not needing whole again
Nut stem material is changed, and has saved precious materials, has saved cost.
4th, wear resistant spray nozzle borehole jack is provided with inside nozzle head aperture, increased nozzle its wearability, extended it and use the longevity
Life.
5th, the mode that is detachably connected is used between barrel and bushing, processing, dismounting, installation are more convenient, and are allowed to be more easy to clearly
Wash.
6th, bushing is set using two-part, and processing and dismounting are more convenient.
