Description
Technical field
The utility model relates to the plastic extruder screw rod, and especially a kind of single screw rod is moulded the screw rod that wooden extruder is used, and specifically a kind of screw unit can separately be made, and promptly forms the box-like single screw rod of the wooden dedicated set of moulding of monoblock type screw rod after the assembling.
Background technology
At present, the mode that the screw rod of domestic and international single screw extrusion machine all adopts the 38CrMoAlA nitrated steel of whole processing to carry out nitrogen treatment is made, its cementation zone (being wearing layer) thickness only has 0.40～0.70mm, wearing and tearing to screw rod are more serious, if after the cementation zone wearing and tearing, the wearability of screw rod is just very poor, reduce service life greatly, may wear to the plasticizing quality that to a certain degree has a strong impact on material and the extruded velocity of material, the whole screw rod that applying unit has to more renew causes the serious waste of material.
Summary of the invention
The purpose of this utility model is the just necessary integral replacing in case part is worn and torn at existing extruder screw existence, thereby cause the problem of serious waste, but design a kind of screw rod of local replacing wearing part, use cost can descend significantly moulds the box-like single screw rod of wooden dedicated set.
The technical solution of the utility model is:
A kind of box-like single screw rod of wooden dedicated set of moulding, it is characterized in that it is by mandrel 1, some screw units 2, end retaining element 3,4 form, end retaining element 3,4 is installed in two ends of mandrel 1, and some screw units 2 are installed in retaining element 3 successively, on the mandrel 1 between 4, it is circumferentially by keyway arrangements 5 location, and it is axially by described retaining element 3,4 location.
Screw unit 2 comprises reverse screw elements, strong mixing elements, build and press delivery element, weak mixing elements, plastify an element or an above combination of elements in element, weak plasticizing element, the Solid Conveying and Melting element by force.
Key in the described keyway arrangements 5 is an involute shape, and correspondingly described groove also is an involute shape.
Described mandrel 1 is the high strength alloy steel element, high-quality high-speed tool steel or the cemented carbide components of described screw unit 2 for handling through integral quenching.
The utlity model has following advantage:
Screw element of the present utility model quenches through overall vacuum, its integral hardness high conformity, even when part has been worn and torn on the surface, its wearability is still very high, to improve its service life more than 10 times, mandrel adopts high strength alloy steel, can bear very high moment of torsion, can give full play to the comprehensive advantage of high abrasion and high moment of torsion by this combination; Even may wear to the degree of need changing in addition, if change the more serious subelement of wearing and tearing (only account for about 20% of whole screw element length usually, or weight about 10%), can recover original high abrasion and high life again.
The utility model also can be saved the maintenance time of equipment greatly, increases the service time of equipment, reduces the maintenance cost of equipment, reduces raw-material consumption, improves the stability and the reliability of equipment, and economic results in society are very remarkable.
Screw unit of the present utility model can be used as accessory and sells separately, and compound mode is flexible and changeable, can make up according to arts demand, is particularly conducive to the experimental study of extrusion process.
Description of drawings

The specific embodiment
Following structure drawings and Examples are further described the utility model.
Shown in Fig. 1～4.
A kind of special-purpose building block system list screw rod that is used for nylon and magnetic powder material, mainly by mandrel 1, screw unit 2 (comprises reverse screw elements 202, strong mixing elements 203, build and press delivery element 204, weak mixing elements 205, strong plasticizing element 206, weak plasticizing element 207, Solid Conveying and Melting element 208), end retaining element 3,4 is formed its medial end portions retaining element 3,4 are installed in two ends of mandrel 1, end retaining element 3 is equivalent to screw head, and end retaining element 4 is equivalent to sealing shroud, and they also play simultaneously and make the screw element 2 that is installed on the mandrel 1 carry out the function of axial location.Each screw unit 2 is installed on the mandrel 1 between the retaining element 3,4 successively, and it is circumferentially by involute shape keyway arrangements 5 location, and it is axially as previously mentioned by described retaining element 3,4 location.
Mandrel 1 can adopt the high strength alloy steel manufacturing, and screw unit 2 can adopt high-quality high-speed tool steel or carbide alloy manufacturing, handles through integral quenching.
From Fig. 1, in 3 as can be seen, screw rod of the present utility model is made up of multiple screw element, wherein mandrel 1 is used to install screw element 2 and transmits moment of torsion, sealing shroud 4 is used for the sealing of screw rod tail, Solid Conveying and Melting element 208 is used for the conveying of raw and cold material, weak plasticizing element 207 is used for the heating and the compression of material, strong plasticizing element 206 is used for material and further heats, compression and fusing, weak mixing elements 205 is used for the mixing of fused materials and the not further fusing of fused materials, build and press delivery element 204 to be used for the forced conveyance of fused materials, strong mixing elements 203 is used for the complete homogenizing of fused materials and disperses, reverse screw elements 202 is used to improve the density of material, and screw head 3 compresses screw element 2 and is assembled into an integral body.
The value volume and range of product of above-mentioned screw element 2 can increase and decrease as required during concrete enforcement, for example can utilize mandrel 1 to add strong mixing elements 203 in the screw element 2, build and press delivery element 204, weak mixing elements 205, strong plasticizing element 206, weak plasticizing element 207, Solid Conveying and Melting element 208 are overlapped to form one and are used to mould wooden moulding and extrude the bolt special of extruding with plastic-aluminum combined core material plasticizing.
In a word; no matter how the kind of screw element and quantity increase and decrease, which kind of circumferential locate mode screw element and mandrel adopt; all be considered to be equivalence of the present utility model and replace so long as screw element 2 and mandrel 1 separately made and change split type easily (building block system) screw rod, and belong to the row of protection domain of the present utility model.
