Description
Technical field
The utility model relates to machinery fields, more particularly to are packed for the processing mold of hard tube, especially a kind of production rank
The monolithic tank cold-punching mold of terraced wall thickness.
Background technique
With the demand of domestic market, inhalator jar is using more and more extensive.Inhalator jar is in process, cold using formed punch
Punch forming.When filling due to inhalator jar, need the oral area of inhalator jar to need enough pressure-bearings, prevent aluminium pot oral area from deforming and drawing
Play leakage.In the prior art, it is substantially uniform up and down to produce inhalator jar wall thickness manufactured by the molding die of inhalator jar, exists
Following disadvantage: if (1) aluminium pot oral area needs to reach pressure-bearing, lower wall thickness can only all thicken simultaneously on can body, thus waste aluminium flake.
(2) wall thickness of inhalator jar is consistent, since pressure is not buffered, can reduce the service life of mold.(3) oral area intensity is inadequate, can
It can will cause and oral area deformation is caused to cause to reveal when envelope fills, therefore, a kind of monolithic tank cold-punching mold producing ladder wall thickness will
Possess good market prospects.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of ladder wall thickness of producing
Monolithic tank cold-punching mold, it is easy to use, save a large amount of cost.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
The utility model provides a kind of monolithic tank cold-punching mold for producing ladder wall thickness, by mold core, mold core Air blowing valve, outer
Circle, inner ring, formed punch and formed punch Air blowing valve are constituted, the mold core be it is inverted T shaped, top set is embedded in the inner ring chamber, head
For indent disc, edge is circular arc wedge angle, is coaxially arranged with model hole on the mold core shaft core position, the mold core that is nested is blown
Air valve, model hole is coaxially arranged on the inner ring shaft core position, and the model hole inlet is equipped with entrance circular angle and transition
Section, changeover portion inlet angle are to be further added by with vertical line at 2 ° of draft angles, and in following distance into 5 ° with vertical line
The head sizes of ladder wall thickness profile angle, the formed punch are bigger than punch body portion size, and be nested punching on the formed punch shaft core position
Head Air blowing valve.
As a kind of optimal technical scheme of the utility model, the outer ring is made of mould steel, and the inner ring is by wolfram steel
Composition.
As a kind of optimal technical scheme of the utility model, the ladder wall thickness shaping position in the inner ring chamber is according to aluminium
The thickness of the length of tank and aluminium flake determines.
As a kind of optimal technical scheme of the utility model, the mold core Air blowing valve and the formed punch Air blowing valve are equal
For class cone.
The utility model beneficial effect achieved is: the utility model has the advantages of simple structure, cheap, and practicability
By force, aluminium flake is shifted onto inside inner ring by formed punch, is shifted onto after withstanding mold core, formed punch continues impact extrusion forward, and aluminium flake can be with punching
Head outer wall and inner ring internal chamber wall are squeezed extensions, since inner ring internal chamber wall is transition angle, therefore in the wall thickness meeting of transition position tank body
Gradually thinning with the extruding forward of formed punch, until the wall thickness of tank body will be almost the same when straightway, after the completion, mold core is blown
Air valve and the movement of formed punch Air blowing valve, tank body is demoulded, and is entered back into track and is carried out next step processing, by being turned over below
Side processing after, higher pressure can be born than conventional aluminium tank mouth portion, at the same also avoid due to pressure-bearing it is inadequate caused by leakage,
The quality level of monolithic tank is effectively improved, and reduces the manufacturing cost of aluminium pot, has saved a large amount of cost, uses simple side
Just, there are good economic benefit and social benefit, be suitble to promote the use of.

Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment: as shown in Figs. 1-2, the utility model provides a kind of monolithic tank cold-punching mold for producing ladder wall thickness, by
Mold core 1, mold core Air blowing valve 5, outer ring 2, inner ring 4, formed punch 3 and formed punch Air blowing valve 6 are constituted, the mold core 1 be it is inverted T shaped, on
Portion's set is embedded in 4 chamber of inner ring, and head is indent disc, and edge is circular arc wedge angle, same on 1 shaft core position of mold core
Axis is provided with model hole 7, and be nested the mold core Air blowing valve 5, is coaxially arranged with model hole 7, institute on 4 shaft core position of inner ring
7 inlet of model hole is stated equipped with entrance circular angle and changeover portion, changeover portion inlet angle is with vertical line into 2 ° of draft angles, and
Following distance is further added by with vertical line into 5 ° of ladder wall thickness profile angles, and the head sizes of the formed punch 3 compare punch body
Portion's size is big, and be nested formed punch Air blowing valve 6 on 3 shaft core position of formed punch.
In order to make this kind produce the monolithic tank cold-punching mold of ladder wall thickness, easy to use, work efficiency is high, the outer ring 2
It is made of mould steel, the inner ring 4 is made of wolfram steel, and the ladder wall thickness shaping position in 4 chamber of inner ring is according to the length of aluminium pot
The thickness of degree and aluminium flake determines that the mold core Air blowing valve 5 is class cone with the formed punch Air blowing valve 6.
When the utility model is used, being shifted aluminium flake inside inner ring 4 by formed punch 3, shift onto after withstanding mold core 1, rushes
First 3 continue impact extrusion forward, and aluminium flake can be squeezed extension with 3 outer wall of formed punch and 4 internal chamber wall of inner ring, since 4 internal chamber wall of inner ring is
Transition angle, thus the wall thickness of transition position tank body can be gradually thinning with the extruding forward of formed punch 3, until when straightway, tank
The wall thickness of body will be almost the same, and after the completion, mold core Air blowing valve 5 and formed punch Air blowing valve 6 act, and tank body is demoulded, is entered back into
Track carries out next step processing, by the way that higher pressure can be born than conventional aluminium tank mouth portion after carrying out flange processing below,
Simultaneously also avoid due to pressure-bearing it is inadequate caused by leakage, effectively improve the quality level of monolithic tank, and reduce aluminium pot
Manufacturing cost.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
