Abstract
The utility model discloses a kind of Novel barrel, comprise machine barrel body (1), lining (2) and junction of the edges of two sheets of paper screw (3), described lining (2) is set in the both sides of machine barrel body (1), and is fixed by junction of the edges of two sheets of paper screw (3).Novel barrel of the present utility model, structure is simple, easy to manufacture, has taken into account the wearability of difficulty of processing and machine barrel, has met the requirement of big L/D ratio unit to latter end machine barrel high-wearing feature.
Description
Technical field
The utility model relates to a kind of Novel barrel.
Background technology
In prior art, extruder barrel is as the core component of extruder, act on most important, and one of development trend of current large-size extruder namely: the draw ratio of unit strengthens gradually, the application scenario of extruder has no doubt been widened in the increasing of unit draw ratio, but also exacerbate the wearing and tearing of extruder latter end machine barrel, this just has higher requirement to the wearability of extruder latter end machine barrel.
Utility model content
The purpose of this utility model is to provide a kind ofly has taken into account the wearability of difficulty of processing and machine barrel, meets the Novel barrel of big L/D ratio unit to the requirement of latter end machine barrel high-wearing feature.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of Novel barrel, comprise machine barrel body (1), lining (2) and junction of the edges of two sheets of paper screw (3), described lining (2) is set in the both sides of machine barrel body (1), and is fixed by junction of the edges of two sheets of paper screw (3).
The lining (2) that described lining (2) adopts two joints isometric.
The inside heap of described lining (2) is welded with hard, wear-resistant alloy.
Described lining (2) is mounted and dismounted by hoisting screw (4).
A kind of Novel barrel of the utility model, structure is simple, easy to manufacture, has taken into account the wearability of difficulty of processing and machine barrel, has met the requirement of big L/D ratio unit to latter end machine barrel high-wearing feature.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of Novel barrel of the utility model.
Fig. 2 is the side view of a kind of Novel barrel of the utility model.
In figure: 1, machine barrel body; 2, lining; 3, junction of the edges of two sheets of paper screw; 4, hoisting screw.
Detailed description of the invention
As depicted in figs. 1 and 2, Novel barrel, comprise machine barrel body 1, lining 2 and junction of the edges of two sheets of paper screw 3, lining 2 is set in the both sides of machine barrel body 1, and fixed by junction of the edges of two sheets of paper screw 3, lining 2 is mounted and dismounted by hoisting screw 4, Novel barrel of the present utility model, do not adopt the structure of overall lining, and the lining 2 adopting two joints isometric is set in machine barrel body 1 both sides by dimensional fits, cut to lengthen helical pitch (screw rod helical pitch is about 300mm) left and right of lining 2, lining 2 inner built-up welding hard, wear-resistant alloy, screw rod end section by screw rod hold up thus play a supporting role, service life be before 2-3 not with bush structure doubly, the property easy to assemble of lining 2 makes once bush inside wearing and tearing are excessive, repair welding alloy can be dismantled again or more renew cover, do not need to change whole joint machine barrel, save cost, shorten the cycle.
Claims (4)
1. a Novel barrel, is characterized in that: comprise machine barrel body (1), lining (2) and junction of the edges of two sheets of paper screw (3), described lining (2) is set in the both sides of machine barrel body (1), and is fixed by junction of the edges of two sheets of paper screw (3).
2. a kind of Novel barrel according to claim 1, is characterized in that: the lining (2) that described lining (2) adopts two joints isometric.
