Description
The application is application number 201510052337.1, on 01 30th, 2015 applying date, title " vacuum extruder pug
The divisional application of extrusion method ".
Technical field
The present invention relates to brick-making technology field more particularly to a kind of vacuum extruder pug extrusion sides with extruding runner
Method.
Background technology
It is not shunk after being sintered due to sintering heat-reserving brick, the common quality defect of appearance is fewer than other wallings very much, therefore is building
Industry is built to be more and more widely used.With sintering heat-reserving brick application and generally use, vacuum extruder
Application field also constantly expands, and relevant device rapidly develops, and the requirement of critical component molding die steps up.Generally make at present
Molding die is small there is extrusion pressure, pug mixing it is uneven the problems such as, this seriously restrict sintered perforated brick towards
Pass is tiny and the direction that is staggered is developed, and domestic vacuum extruder can't produce the sintering that pass is tiny and is staggered at present
Insulating brick, this is because the sintering heat-reserving brick of this pass is very high to former and technological requirement.It requires vacuum brick extruding
Machine has larger extrusion pressure, and pug can be made to be sufficiently mixed uniformly.If pressure is too small, the wet base intensity of extrusion with regard to low,
It is yielding when dry.It needs to design a kind of extruding runner of vacuum extruder to this, its device is allow to increase to pug
It squeezes, is uniformly mixed pug, meets the forming requirements of high quality sintering heat-reserving brick.
When vacuum extruder is worked, pug is advanced by screw reamer at head in machine barrel, in head and
Machine oral area divides extrusion forming to form mud item.Pug is inadequate in the prevalence of briquetting pressure at the time of molding, and pug mixing is uneven, from
And adobe cohesive force is caused to decline, the defects of insufficient strength, when brick bat drying easily deforms.In addition, pug squeeze out when,
Resistance and friction by head inner wall increase pug temperature, lead to pug moisture loss, mud quadrangle easily generates cracking
Phenomenon.Therefore, it is necessary to design a kind of novel lubricating and cooling to solve the problems, such as this.
In addition, since the pug in vacuum extruder machine barrel is pushed ahead by the mode that screw reamer rotates, so
Pug still rotates after head is entered, and lamination is generated so as to cause pug, in some cases, what extrusion molding was formed
Layering can result in adobe internal structure existing defects, decline adobe qualification rate.Therefore, it is necessary to design a kind of novel extruding
Agitating device reduces pug lamination.

For a kind of with the vacuum extruder pug extrusion method for squeezing runner, implement vacuum extruder such as Fig. 1 institutes that this method uses
Show, including head 25, machine barrel 24, rotatable screw reamer 21 is connected in machine barrel 24, it is fixed between machine barrel 24 and head 25
It is connected with and squeezes runner 23, squeezing runner 23 has the cavity of front and rear perforation, and the aperture of cavity is gradually reduced from middle part to both ends,
It squeezes the pug segmentation for being fixedly connected in runner 23 and being useful for carrying out pug cutting and squeezes agitating device 22；
The method includes：
Pug is pushed to extruding runner by spiral reamer, and the pug is cut into a plurality of by pug segmentation extruding agitating device
The mud item that straight line squeezes out；
The mud item that a plurality of straight line squeezes out divides the extruding stirring area for squeezing agitating device and deviating from supplied materials direction in pug
Again it is extruded to form a whole mud item；
Whole mud item sequentially via head and the core being connect with head tool and machine mouth, is formed with the hole that is evenly distributed
Mud item to be slit.
Since the aperture of cavity from middle part to both ends is gradually reduced namely forms, a middle part protrudes can accommodate more
The cavity of more pugs.Pug collects in the cavity, and stops rotating via the effect of pug segmentation extruding agitating device, and by
Segmentation is stirred.Pug collect after again through head extrusion so that the brick of formation is fine and close, intensity is high.
Said program provided by the invention, pug can be sufficiently mixed by squeezing runner 23, and mud material forming is finer and close, position
Agitating device is squeezed in squeezing the segmentation of the pug inside runner, pug mixing can be made more uniform, reduce pug and twisted by spiral
Lamination when knife squeezes out improves the quality of institute's brickmaking.
Further, as shown in Figure 2,3, pug segmentation extruding agitating device includes multiple segmentation blades 4 arranged in a crossed manner,
