Abstract
A kind of ultra-high molecular weight polyethylene extruder core expander is the utility model is related to, belongs to extruder core expansion equipment technical field.The utility model mainly solves the technical problem that production cost existing for existing ultra-high molecular weight polyethylene extruder is high, extrusion die Renewal process is complicated, occupation area of equipment is big.The technical solution of the utility model is：A kind of ultra-high molecular weight polyethylene extruder core expander, including core, the core end face are provided with concave mouth, wherein：It also includes annular expander, annular expander left end face is provided with the male half coupling being engaged with core concave mouth, annular expander is along the circumferential direction uniformly provided with some bolts hole, and chamfered transition is used between annular expander left end face and annular expander lateral surface；The annular expander is bolted with core.The utility model has the advantages that production cost is low, simple to operate, reasonable in design.
Description
Technical field
The utility model belongs to extruder core expansion equipment technical field, more particularly to a kind of ultra-high molecular weight polyethylene
Extruder core expander.
Background technology
Ultra-high molecular weight polyethylene (HMW-PE) refers to linear structure polyethylene of the viscosity average molecular weigh more than 1,500,000, it
It is a kind of thermoplastic engineering plastic of excellent performance, it combines the outstanding performance of many plastics, especially in impact resistance, wear-resisting
Damage, resistant to chemical etching, self-lubrication, high in environmental protection and absorb impact property these aspect be existing plastics in peak.
Ultrahigh molecular weight polyethylene tubing description is more, and each size pipe all needs to buy the machine of dimension customized
Also therefore head mould has, and production external diameter differs the extrusion die that less tubing is also required to customize dimension respectively, and production cost
And increase；And extrusion die Renewal process is complicated, the extrusion die changed needs special warehouse to be placed, floor space
Greatly.
The content of the invention
A kind of the shortcomings that the purpose of this utility model is to overcome prior art, there is provided ultra-high molecular weight polyethylene extruder
Core expander, solve production cost height, extrusion die Renewal process existing for existing ultra-high molecular weight polyethylene extruder and answer
Technical problem miscellaneous, occupation area of equipment is big.
The utility model is achieved through the following technical solutions：
A kind of ultra-high molecular weight polyethylene extruder core expander, including core, the core end face are provided with recessed stop
Mouthful, wherein：It also includes annular expander, and annular expander left end face is convex provided with being engaged with core concave mouth
Seam, annular expander are along the circumferential direction uniformly provided with some bolts hole, and annular expander left end face expands with annular
Chamfered transition is used between exhibition device lateral surface；The annular expander is bolted with core.
Further, the external diameter of the annular expander is bigger 10~15mm than core external diameter.
The utility model installs annular expander additional on the core end face of original extruder, smaller in production external diameter difference
Tubing when, it is simple to operate, cost is low without changing extrusion die；In annular expander left end face with core concave mouth
The setting for the male half coupling being engaged, play spacing, centering；Annular expander left end face and annular expander outside
Chamfered transition is used between face, is advantageous to the circumference tilt extension of tubing.
Compared with prior art, the utility model has production cost low, simple to operate, reasonable in design etc. excellent
Point.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is enlarged drawing at the I of Fig. 1.
In figure：1- annulars expander, 2- male half couplings, 3- bolts hole, 4- cores, 5- mouth molds, 6- heads, 7- vacuum tanks.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, a kind of ultra-high molecular weight polyethylene extruder core expander in the present embodiment, including core
Mould 4, the end face of core 4 are provided with concave mouth, wherein：It also includes annular expander 1, the left-hand end of annular expander 1
Face is provided with the male half coupling 2 being engaged with core concave mouth, and annular expander 1 is along the circumferential direction uniformly provided with some bolts hole
3, chamfered transition is used between the left end face of annular expander 1 and the lateral surface of annular expander 1；The annular expander
1 is bolted with core 4.
Further, the external diameter of the annular expander 1 is bigger 10~15mm than the external diameter of core 4.
The utility model is applied to SHJS-200-25 type ultra-high molecular weight polyethylene extruders.
The course of work of the present utility model：
The male half coupling 2 in the left end face of annular expander 1 is engaged with the concave mouth on the end face of core 4 first, led to
Cross bolt to be fixed to annular expander 1 on the end face of core 4, then starting ultra-high molecular weight polyethylene extruder can be real
The extension of existing core, produce the ultrahigh molecular weight polyethylene tubing of plurality of specifications.
The utility model can be embodied without departing from the spiritual or substantive of invention in a variety of forms, so should manage
Solution, above-described embodiment is not limited to foregoing details, and should widely be explained in claim limited range, therefore falls into
Claim or change in its equivalent scope and remodeling all should be claim and covered.
