Abstract
The utility model discloses a casement shunt during solid powder column shaping is used, including outer lane and center bevel, the outer lane is circular ring shaped structure, and center part is a center bevel, and outer lane and center bevel pass through splice bar fixed connection, form an overall structure, the center bevel hole is the toper through -hole. When the propellant material passed through conical hole in the mould, the material advanced the tip play from the conical hole main aspects, and the material is by further compression to the closely knit degree of center part material has been improved. Have bigger shaping area and press scaling, have better effect to improving the shaping quality.
Description
Technical field
The utility model is related to spiral pressure stretch manufacture field, and more particularly to a kind of solid column shaping is shunted with hollow type
Device.
Background technology
At present, civilian spiral companding shaping solid column still adopts needle frame device, and the punch block being installed in mould is to use
In a device for being molded hollow powder column, the mould pin for simply below installing punch block is changed into after the shorter taper tail cone of length just
For shaping solid powder column.Because punch block core is solid, the disadvantage for certainly existing is the powder column central part for molding
Position packing is poor, and particularly when the solid column being relatively large in diameter is molded, core packing is very poor.In addition, for shaping very
In mould it is that punch block is not installed during the hollow medicinal strip of minor diameter, therefore, it is impossible to realize the shaping of the solid column of minor diameter.
Utility model content
The purpose of this utility model is to provide a kind of solid column shaping hollow type current divider, and it is solid that solution is molded
The problem of powder column centre packing difference, especially when the solid column being relatively large in diameter is molded, core packing is very poor
Problem.
The technical solution of the utility model is：Hollow type current divider is used in a kind of solid column shaping, it is characterised in that：Including
Outer ring and center cone, outer ring is circular ring, and centre is a center cone, and outer ring and center cone are fixed by dowel
Connection, forms an overall structure；Center cone endoporus is conical through-hole.
Preferably, also including ring-type muscle 22, ring-type muscle 22 is located between outer ring 1 and center cone 3, by straight muscle respectively with outward
Circle 1 and center cone 3 connect.
Preferably, towards mould inner cone direction, small end is towards after mould at the big end of the inner conical surface 31 of center cone
Cone direction.
Preferably, the section of ring-type muscle and straight muscle is drops streamlined.
Preferably, the longitudinal section of the male cone (strobilus masculinus) of center cone is in streamlined.
Beneficial effect：The utility model has round taper hole due to center, when propellant material passes through cone in mould
Kong Shi, material from the big end of round taper hole enter it is little bring out, material is further compressed, so as to improve the closely knit of centre material
Degree.Under the same conditions, compared with punch block structure, hollow type current divider due to without central solid portion and center for circle
Taper, with bigger shaping area compression ratio, has more preferable effect for Forming Quality is improved, and is particularly capable of achieving
More than 300mm major diameters solid column is molded.
Description of the drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the A-A profiles of Fig. 1.
In figure：1. outer ring, 21. straight muscle, 22 ring-type muscle, 23. straight muscle, 3. center cone, 31. center cone inner conical surfaces, 32. centers
Cone male cone (strobilus masculinus).
Specific embodiment
To make the purpose of this utility model, content and advantage clearer, specific embodiment of the present utility model is made
Describe in further detail.
As depicted in figs. 1 and 2, the utility model provide solid column shaping use hollow type current divider, by the first straight muscle 21,
The straight muscle 23 of ring-type muscle 22 and second connects outer ring 1 and center cone 3 to form an entirety；
Outer ring 1 and center cone 3 are necessary structures, and outer ring is the circular ring consistent with punch block, and centre is one
Individual center cone, ring-type muscle 22 be located between outer ring 1 and center cone 3, by the first straight muscle 21 and the second straight muscle 23 respectively with outer ring 1
It is connected with center cone 3, the quantity of ring-type muscle 22 is 1 (only as example, but not limited to this).When shaping small diameter it is solid
During powder column, ring-type muscle can be not provided with, outer ring 1 is directly connected to by straight muscle 21 and forms an entirety with center cone 3.First straight muscle 21
Circumferentially it is uniformly distributed with the second straight muscle 23, quantity arranges according to mould size reasonable and (is disposed as 4 herein, but not only limits
In this), the first straight muscle 21 be able to can also be differed with the quantity of the second straight muscle 23 with identical, and can not be on the same line.
The effect of outer ring 1 has been fixation, and outer ring 1 is arranged at mould inner cone (expansion segment) and rear cone (converging portion)
Between, and be fixed by inner cone and rear cone.
Straight muscle 21, ring-type muscle 22 and the straight Main Function of muscle 23 have been connection functions, in order to reduce the resistance to spice, section
Make drops streamlined.
The male cone (strobilus masculinus) 32 of center cone is also in streamlined, also for the resistance reduced to spice.
The big end of the inner conical surface 31 of center cone towards inner cone direction, small end towards rear cone direction, because there is cone at center
Hole, when spice in mould pass through round taper hole when, from the big end of round taper hole enter it is little bring out, spice is further compressed, so
Be conducive to improving the packing of centre spice, such that it is able to realize the shaping of the major diameter powder column of more than diameter 300mm.
Under the same conditions, compared with punch block structure, hollow type current divider is due to without central solid portion, having
Bigger shaping area compression ratio, has more preferable effect for Forming Quality is improved.The device is gone back compared with needle frame device
There is a benefit to can be to avoid the occurrence of the punch block trace for running through, can preferably avoid powder column from occurring the feelings for rupturing during storage
Condition.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from the utility model know-why, some improvement and deformation can also be made, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
