Abstract
The present invention relates to a kind of production of carrier pug and moulding process, including the web plate being disposed vertically with mud extraction direction, the mud inlet end of the web plate is provided with block, the block is identical with the shape of web plate, the section of the block and web plate is into disc structure, the centre position of the block and web plate is provided with the sphere of projection, and marginal portion is plane；Equally distributed hole is provided with the web plate；Mud section passes through block and web plate extrusion molding.The present invention is compact-sized, reasonable, it is easy to operate, by changing structure of blocking, in the center section of block using sphere block and web plate, edge is blocked using plane and web plate, middle mud volume too bulky grain is so effectively avoided easily in the aggregation of block center section, has more been aggravated the mud extraction pressure of center section, has been made extrusion pug pressure distribution uniform.
Description
Technical field
The present invention relates to carrier pug production technical field, especially a kind of carrier pug production and forming method.
Background technology
Due to state five, the requirement of state six is constantly lifted, and present carrier wall thickness develops to thin-walled, wall thickness 0.2mm to 0.17mm
Even accomplish 0.10mm.Requirement more and more higher to pug, the formula and technical process of the selection product of raw material are to first have to solve
Certainly, formula good again but in actual production, then advanced equipment cannot guarantee that in pug do not have large granular impurity and big
Grain raw material or stiff block etc..This directly influences the extrusion molding of carrier.
In carrier extrusion molding because the thinner mud section for also requiring extrusion of wall thickness is uniform, shaping so just can guarantee that
Product is unlikely to deform, and forming defect is few.
Conventional way is that pugging operation is blocked in pug mill or extruder stack shell plus together, and the mesh number of block is not according to
It needs to be determined that, (product wall thickness is thinner, and required block mesh number is bigger) block keeps off one block of multi hole surface web plate and fuselage again below together
It is fixed together.
The advantages of Normal practice is：Bulky grain is intercepted, ensures shaping not plug-hole, pug densification, increases retrospective, but also
It is to have the disadvantage that：
1st, mud extraction pressure is uneven, pug lack of homogeneity, and the middle fast pressure of mud extraction is small, shows as loose surrounding among pug
It is relatively compact, it is unfavorable for the extrusion molding of carrier.
According to Bernoulli equation：
P+1/2 ρ v2+ ρ gh=constants
Height where the flow velocity g acceleration of gravity h of the P pressure ρ fluid density v fluids points
Flow velocity eminence pressure is low, and flow velocity lower pressure is high.
2nd, block fragile：Middle mud volume is big.Blocking, center section is easy to wear, and broken among general block, surrounding is blocked
Net or good, it is necessary to frequent draping
3rd, efficiency is low：Plug-hole bulky grain is easily assembled among screen cloth, reduces extruded velocity.
The content of the invention
The shortcomings that the applicant is directed in above-mentioned existing production technology, there is provided a kind of carrier pug production and forming method,
So as to.
The technical solution adopted in the present invention is as follows：
A kind of carrier pug production and forming method, including the web plate being disposed vertically with mud extraction direction, the one of the web plate
End is provided with block, and the block is identical with the shape of web plate, and the section of the block and web plate is described to block into disc structure
The centre position of net and web plate is provided with the sphere of projection, and marginal portion is plane；Equally distributed hole is provided with the web plate
Hole；Mud section passes through block and web plate extrusion molding.
Beneficial effects of the present invention are as follows：
The present invention is compact-sized, reasonable, easy to operate, and by changing structure of blocking, ball is used in the center section of block
Face is blocked and web plate, and edge is blocked using plane and web plate, so effectively avoids middle mud volume too bulky grain and holds
Easily in the aggregation of block center section, the mud extraction pressure of center section is added, makes extrusion pug pressure distribution uniform.
Brief description of the drawings

Fig. 2 is the structural representation that the present invention blocks.
Fig. 3 is the structural representation of web plate of the present invention.
Fig. 4 is the sectional view of mud section of the present invention.
Wherein：5th, mud section；6th, block；7th, web plate；8th, sphere；9th, hole.
Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is illustrated.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present embodiment carrier pug production and forming method, including with mud extraction side
To the web plate 7 being disposed vertically, one end of web plate 7 is provided with block 6, and block 6 is identical with the shape of web plate 7, block 6 and web plate 7
Section into disc structure, the centre position of block 6 and web plate 7 is provided with the sphere 8 of projection, and marginal portion is plane；Net
Equally distributed hole 9 is provided with plate 7；Mud section 5 passes through block 6 and the extrusion molding of web plate 7.
The present invention uses brand-new block mode, has guidance quality to pug, is provided simultaneously with the place to go bulky grain of traditional handicraft
Function.
Using mud material forming method of the present invention, resulting pug uniformity is more preferable, and can be carried out according to actual condition
Adjustment.
Using mud material forming method of the present invention, centre position pug crosses extrusion force when blocking 6 forward, also by sphere 8
Shearing force outside sensing, reduce middle mud extraction speed, add mud extraction speed on side,
According to Bernoulli equation：
P+1/2 ρ v2+ ρ gh=constants
Height where the flow velocity g acceleration of gravity h of the P pressure ρ fluid density v fluids points
Flow velocity eminence pressure is low, and flow velocity lower pressure is high.
By reasonably configure block arc range and with sphere 8 block 6, it becomes possible to adjust " side " " in " mud extraction speed
Degree is consistent, i.e., " side " " in " unanimously namely pug uniformity is consistent for pressure.
6 life-spans of blocking are longer, and 6 centre of blocking more efficient extrudes pug.
Because block 6 is cambered, plug-hole bulky grain is not easy to assemble among screen cloth, most of under the effect of pug extrusion force
Grain can be moved to screen periphery position, have substantially no effect on extruded velocity.
As Figure 1-4, empirical equation：
R=(1- (Δ 3- Δs 4) * D/2
L：
Select continuous maximum difference in Δ 1, Δ 2, Δ 3, Δ 42 points.It is Δ 2, the difference of Δ 3 maximum in this example, then takes
2nd, the distance in midpoint to the mud section center of circle between 3 is radius L1.Sphere handing-over linear diameter is obtained multiplied by 2D/B
B：Mud section diameter
D:Web plate diameter
L：Sphere joins linear diameter
R：Net diameter
Δ 1, Δ 2, Δ 3, Δ 4 are the pug density value of 1,2,3,4 point of extrusion pug end face and the percentage of overall average
Deviation.
Name two mud section density test examples：
Comparative example：
Empirical equation is calculated (known D=205mm B=205mm)
R=(1- (Δ 3- Δs 4)) * D/2=97mm
According to measuring and can be calculated L=102mm
Example：
Above description is explanation of the invention, is not the restriction to invention, limited range of the present invention is referring to right
It is required that within protection scope of the present invention, any type of modification can be made.
