Abstract

The invention discloses a conical dual-machine-barrel unit with an embedded high-wear-resistant base material. The conical dual-machine-barrel unit comprises a machine barrel extrusion section outer sleeve, a conical wear-resistant sleeve structure with the high-wear-resistant base material, a high-intensity screw and a machine barrel rear section. The dual-machine-barrel unit with the embedded high-wear-resistant base material can be used for extruding materials, is suitable for extruding of highly filled materials, and is rapid and convenient to replace and low in cost. Compared with the prior art, the conical dual-machine-barrel unit has the effects that the abrasion resistance of machine barrels is improved obviously, a wide range of materials can be adopted, the production cost is reduced and the like.

Description

Inlay the cone double machine barrel of high abrasion base material
Technical field
The present invention relates to the two parts of extruding of cone, is a kind of cone double machine barrel that is applicable to plastic extrusion, is specially adapted to the wear-resisting cone double machine barrel of high inserts.
Background technology
Present cone double machine barrel, can not meet the use of some high fill materials, causes the extruding zone serious wear to machine barrel, has reduced the plasticizing of material and the output of extruder, affects the quality of article of manufacture, and it changes whole machine barrel, causes cost high.
Summary of the invention
The problems of the prior art to be solved by this invention are: because existing cone double machine barrel base material wears no resistance in the time using high fill material, service life is short, and spent material narrow range is changed machine barrel cost high in the short time, cause production cost high.Now also have and do wear-resistingly in machine tube inner wall spraying bimetallic alloy, but in the process using, alloy-layer has obscission, and to improving wear-resisting DeGrain.
The present invention is for solving the aforementioned problems in the prior, the technical scheme adopting is in existing machine barrel, to inlay high abrasion base material, high abrasion resisting material is done to tapered 8 word covers and machine tube inner wall and closely cooperate, make to bore double machine barrel in use not easy to wear, be more suitable for high fill material and extrude.Using identical material in the situation that, the machine barrel of inlaying high abrasion resisting material, approximately improves 1.5-2 service life doubly, and inlays high abrasion base material difficult drop-off raising the cost 20% in the situation that than former machine barrel.
The cone double machine barrel of inlaying high abrasion base material of the present invention, comprises machine barrel extruding zone overcoat, high abrasion base material taper wear-resistant sleeve structure, high-strength screw, machine barrel back segment; It is characterized in that: in extruding zone overcoat, inlay high abrasion base material taper wear-resistant sleeve structure, 8 word covers and machine tube inner wall that high abrasion base material taper wear-resistant sleeve structure is taper closely cooperate; Described machine barrel extruding zone overcoat rear end is provided with screw hole; Cylinder extruding zone overcoat adopts high-strength screw to be connected with machine barrel back segment by screw hole, greatly reduces costs, and it is quick, convenient to connect.Improved the service life of machine barrel, also improved the plasticizing of material and the quality of product, after wearing and tearing, only needed dismounting high-strength screw newly inlay high abrasion tapered sleeve in long-time use procedure, it is quick, convenient to change, and greatly reduces costs.
The described machine barrel of inlaying high abrasion base material can meet extruding of material, the extruding of more applicable high inserts, and change fast, convenient, cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of inlaying the cone double machine barrel of high abrasion base material
Fig. 2 be inlay high abrasion base material cone double machine barrel side view
Detailed description of the invention
How further illustrate the present invention below in conjunction with accompanying drawing realizes.
As shown in Figure 1, inlay the cone double machine barrel of high abrasion base material, comprise machine barrel extruding zone overcoat 1, high abrasion base material taper wear-resistant sleeve structure 2, high-strength screw 3, machine barrel back segment 4; It is characterized in that: in extruding zone overcoat 1, inlay high abrasion base material taper wear-resistant sleeve structure 2; 8 word covers and machine tube inner wall that high abrasion base material taper wear-resistant sleeve structure 2 is taper closely cooperate; Described machine barrel extruding zone overcoat 1 rear end is provided with screw hole; Cylinder extruding zone overcoat 1 adopts high-strength screw 3 to be connected with machine barrel back segment 4 by screw hole, greatly reduces costs, and it is quick, convenient to connect.
The present invention and prior art contrast, its effect is the wearability that has significantly improved machine barrel, spent material is wide, has reduced the characteristics such as production cost.
