Description
Technical field
The present invention relates to bead structures of small shaped tank and preparation method thereof, especially punching press button bottom curling and sealing method.
Background technique
The bottom cover curling and sealing method of the barrel cage of the prior art mostly uses seaming assembly machine to form, and principle is：First by bucket bottom
Top is put on ladle body, then uses two chuck clampings, and is pushed up ladle body and bucket bottom and rotated together, then crimping briquetting roller by getting on.Make
Along idler wheel groove profile curvilinear crimp, after idler wheel top ladle body completely, crimping has been basically formed, and is finally used for bucket bottom top and ladle body edge
Two amendment idler wheels make crimping become required shape by up, crimping being compressed, and eliminate rebound.Such method is main
It is the seaming for round barrel cage.And irregular can is during seaming, and since four sides are not rounded, seaming position every bit and tank
Body centre distance all differs, and seaming roller cannot move in a circle, so the idler wheel of round can circles, the volume of can body rotation
Envelope mode is not suitable for the seaming of irregular can.For example, the seaming of the more small special-shaped box such as chewing gum box, using irregular can seaming
Machine, it is necessary to be that can body is stationary, and sealing roller does the structure type of forming movement.There are two types of basic for irregular can profiling seaming
Pattern, one is pot pattern, another kind is non-pot pattern.This two ways makes the design of seaming roller and requires more
Complicated, production more difficulty, since turn curvature changes greatly, but also inertial change of the seaming roller at this increases severely, sternly
Important place affects seaming quality, also limits the raising of production capacity.Also be easy to appear seaming is tight, precision not enough, corrugate,
Crimping runs over and injure, ruptures etc. the phenomenon that not meeting quality standard.Therefore, general small-sized irregular can mostly uses greatly mould punching seaming
Molding technique.
The mould punching seaming of the irregular can body and tank bottom (top) of the prior art all uses double seam, technology letter
Single, defect is poor sealing, easy to leak, it is impossible to be used in it is required that the higher canister of leakproofness.
Summary of the invention
The object of the present invention is to provide a kind of five layers of bead structure of small-sized three pieces irregular can and its curling and sealing methods, it utilizes mould
Tool punching press crimping changes the bead structure of the prior art, effectively improves the sealing performance of crimping, and producer
Method is simple, high production efficiency.
The small-sized five layers of bead structure of three pieces irregular can of the present invention, the can body rim roll 11 including same model board making, tank
Bottom rim roll 21, the can body rim roll 11 coat 21 curls inward 90 of tank bottom rim roll.；Form the can body rim roll layer being arranged successively
215 layers of tank bottom of rim roll layer 114-- of 213-- can body of rim roll layer of 212-- tank bottom of rim roll layer of 111-- tank bottom total five-layer structure.
Above-mentioned five layers of bead structure of small-sized three pieces irregular can, with the board making can body and tank bottom of 0.2--0.3mm thickness,
The length of its can body rim roll 11 is 4.5--5.5mm, and the length of tank bottom rim roll is 3.5--4.5mm.
Above-mentioned five layers of bead structure of small-sized three pieces irregular can, with the board making can body and tank bottom of 0.23mm thickness, tank
The length of body rim roll 11 is 5mm, and the length of tank bottom rim roll 21 is 4mm.
The curling and sealing method of above-mentioned small-sized five layers of bead structure of three pieces irregular can, it is characterised in that include the following steps：
1. the plate cutting for choosing 0.2--0.3mm thickness is cut；Can body and tank bottom are made respectively；
2. the length of the end pre-bending is 0.8--1.2mm by the end pre-bending of can body rim roll 11；By tank bottom rim roll 21
End pre-roll, the length of the end pre-roll are 0.8--1.2mm；
It is placed on bed die 3. tank bottom is placed in can body, the root of tank bottom rim roll 21 and the root of can body rim roll 11 are located at together
On one horizontal line；
4. tank bottom, can body are carried out one time punching molded；Punching press upper mold is wiring dit, the die cavity of the wiring dit
For the union of semi arch and rectangle, the diameter of semi arch is 2.1mm, and rectangle is 2.1 × 1.05mm；
5. step 4. on the basis of carry out two times punch molding again；The two times punch upper mold is linear mould.
Using above-mentioned five layers of bead structure of small-sized three pieces irregular can, its sealing performance is greatly enhanced compared with prior art,
Humidity resistance can be effectively improved, thus in protecting box food safety.Using molding curling and sealing method of the invention, crimping is not
It can generate " iron tongue ", tight inside crimping, and production method is simple, high production efficiency.

Specific embodiment
Invention is described in further detail with reference to the accompanying drawing：
As shown in Fig. 1, Fig. 2, Fig. 3, the small-sized five layers of bead structure of three pieces irregular can of the present invention, including same model plate system
The can body 1 and can body rim roll 11 of work, tank bottom 2 and tank bottom rim roll 21.When 1 He of board making can body with 0.2--0.3mm thickness
When tank bottom 2, the length of can body rim roll 11 is 4.5--5.5mm, preferably 5mm；The length of its tank bottom rim roll is 3.5--
4.5mm, preferably 4mm.The can body rim roll 11 coats 21 curls inward 90 of tank bottom rim roll.；Form the can body volume being arranged successively
Edge layer 111-- tank bottom rim roll layer 212-- tank bottom rim roll layer 213-- can body rim roll layer 114-- tank bottom layer 215 is total to five-layer structure.Such as
This bead structure, crimping inside tight, effectively improves the leakproofness of seaming structure.The can body rim roll 11 is rolled up with tank bottom
The inside turnup of edge 21, therefore observable flange is not had in can body bottom, the whole decoration result of can body is not by bottom cover crimping
It influences, appearance is also beautiful.
The curling and sealing method of above-mentioned small-sized five layers of bead structure of three pieces irregular can：
Tank bottom and can body are made first, in accordance with the prior art.
As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6,
The first step：By the end 11a pre-bending of can body rim roll 11, the length of end 11a pre-bending is 0.8--1.2mm；By tank
The end 21a pre-roll of bottom rim roll 21, the length of end 21a pre-roll are 0.8--1.2mm；As shown in Figure 3, Figure 4.
Second step：Tank bottom 2 is placed in can body 1 and is placed on bed die, root 21b and the can body rim roll 11 of tank bottom rim roll 21
Root 11b is located in same horizontal line；As shown in Figure 4.
Third step：Tank bottom, can body are carried out one time punching molded；Punching press upper mold is wiring dit, the wiring dit
Die cavity be semi arch and rectangle union, the radius R of semi arch is 2.1mm, and rectangle long side A is 2.1, and broadside B is
1.05mm；As shown in Figure 5.
4th step：It carries out two times punch molding again on the basis of third step, crimping is compressed, eliminate rebound.This two
Secondary punching press upper mold is linear mould.As shown in fig. 6, obtaining bead structure shown in Fig. 7 using linear mould shown in fig. 6.Certainly
It can obtain different linear by changing linear mould, meet the needs of client, such as Fig. 8 according to client to linear requirement
It show flat linear.
