Abstract

The utility model relates to a segment sleeve barrel spiral arc extruding hollow tailing omnidistant screw blade, which is composed of an arc spiral screw blade whose stress surface is a concave, a segment sleeve barrel matched with the front end of the main shaft of the screw blade, the jack of the spiral screw blade hollow pull tail end, etc. The utility model has the advantages of simple structure, convenient installation and operation and manufacture, favorable mixing effect, high work efficiency, easy dismounting, convenient maintenance and wide range of application, the extruding pushing action is enhanced, and the utility model is favorable to extending the service life of the main shaft of the screw blade and the spiral screw blade.

Description

A kind of sections telescopic screw cambered surface extruded hollow hangover whole process is stirred leaf

The utility model belongs to a kind of spiral and stirs crowded propelling unit.

Existingly stir that to squeeze many in the device be to adopt spiral to stir the leaf performance to stir crowded progradation.Particularly the big calculon in rural area (watt) factory use stir mud press brick (watt) equipment, be that the spiral that adopts stirs leaf and stirs the mud machine basically.This class is stirred the subject matter that the machine that squeezes exists: the one, and it is biplanar that spiral stirs leaf, and this leaf that stirs squeezes the chamber and stirs and push through in the journey stirring, and the power that advances of extruding is less forward, and discharging speed is slower; The 2nd, it is directly to be fixed on to stir on the leaf main shaft that spiral stirs leaf, because it is long to stir the stroke that squeezes the chamber, the root that stirs the leaf main shaft accepts that the stirring of import raw material is stressed to be advanced stressed much smaller than stirring stirring, the extruding that the leaf spindle nose accepts grog, stir the leaf spindle nose amplitude of oscillation at work and strengthen, to all being affected in its service life and discharging effect; The 3rd, maintenance difficult after stirring leaf or stirring leaf main shaft damage distortion, be removed the whole leaf main shaft that stirs can keep in repair, and is very inconvenient.

The purpose of this utility model is at the problems referred to above, and a kind of spiral that provides stirs leaf and directly is not fixed on and stirs on the leaf main shaft, stirs the positive a kind of sections telescopic screw cambered surface extruded hollow hangover whole process for the spill cambered surface of work of leaf and stirs leaf.

The method that the utility model is finished is to stir leaf according to spiral to stir crowded stressed less at raw material import position, stirring outlet position, crowded chamber, from small to large, increase the thickness that spiral stirs leaf to the different stress conditions that grog stirs, squeese pressure is bigger, and heat treatment in addition, to improve its mechanical strength and hardness; Simultaneously leaf is stirred on the plane and change that work is positive to be the cambered surface of spill, the extruding progradation of stirring leaf with enhancing into; The leading portion that spiral stirs leaf is fixed on and stirs on the sections sleeve of leaf spindle nose adapted, and all the other departments are hollow hangover, during work, and stirs the leaf main brass and uses; The root that stirs the leaf main shaft has the slotting ear that stirs the jack adapted of leaf tail end with spiral, and the spiral when helping work stirs leaf and main shaft run-in synchronism better, and guarantees the stressed effect of hollow hangover part.Before the work, if the sections sleeve set that originally stirs leaf at the front end that stirs the leaf main shaft, the jack sleeve that stirs the leaf tail end is on the slotting ear that stirs leaf main shaft root, pusher whole process such as propelling are finished and are stirred material, push in the work of can starting shooting.During maintenance, as long as take off sections sleeve and the stock key that has nut that stirs location, leaf main shaft top, this device can be withdrawn from.

The utility model has the advantages that: simple in structure, make, install, use all very convenient; The sections sleeve with stir applying mechanically of leaf main shaft leading portion, help increasing the diameter that stirs leaf main shaft back segment, increase the intensity stir the leaf main shaft, reduce and stir the amplitude of oscillation of leaf main shaft leading portion when work, make it running steadily, prolong the service life of stirring the leaf main shaft; According to the omnidistance stressed rule from small to large of leaf of stirring, increase stir leaf be subjected to force intensity and hardness, help prolonging the service life of stirring leaf, prolong ten times or more than existing equipment its service life; The driving surface that spiral stirs leaf is the spill cambered surface, has strengthened the extruding progradation greatly, stir squeeze effective, high efficiency; It is easy, easy to maintenance to dismantle; Can be common to all kinds of crowded equipment that stir, widely applicable, market outlook are good.

Accompanying drawing 1 is an agent structure scheme drawing of the present utility model, and Fig. 2 is the installation site scheme drawing.

Most preferred embodiment of the present utility model is: the leading portion that spiral stirs leaf (3) is fixed on and stirs on the sections sleeve (1) of leaf main shaft (5) leading portion adapted, the bearing surface (2) that spiral stirs leaf is the spill cambered surface, spiral stirs the jack (4) and slotting ear (6) adapted that stirs leaf main shaft root of the hollow hangover end of leaf, there is the location stock key (7) of band nut on sections sleeve and the top of stirring leaf main shaft adapted, and stirring crowded chamber (9) and stir the leaf main shaft and being installed in respectively on the support (10) of inlet point (8) arranged.

Claims (1)

1. A kind of sections telescopic screw cambered surface extruded hollow hangover whole process is stirred leaf, comprise that spiral stirs leaf, it is characterized in that the leading portion that spiral stirs leaf (3) is fixed on and stirs on the sections sleeve (1) of leaf main shaft leading portion adapted, the bearing surface (2) that spiral stirs leaf is the spill cambered surface, the back segment that spiral stirs leaf is hollow hangover, and its hollow hangover end has and the jack (4) that stirs the slotting ear adapted of leaf main shaft root.
