Description
Technical field
The present invention relates to metal can preparation process fields, more particularly to a kind of swollen type moulding process of special-shaped metal can.
Background technique
Special-shaped metal three-piece can is one of common metal tank, at present abnormal shape metal three-piece can usually using swollen pattern have at
Type, moulding process are as follows: printing tinplate aniseed → cutting printing aniseed is at small tablet → small tablet Cheng Yuan → welding → weld seam
Outer (interior) coating drying → swollen type → tank mouth flange → capping of (interior) coating → weld seam, molding critical process are swollen type outside, due to
Swollen pattern tool is composed of many blocks, has gap between swollen type mold block and block, can body after swollen type is caused to have different journeys
The trace of degree seriously affects can body appearance, and applicant designs a kind of swollen type moulding process of novel special-shaped metal can thus.
Summary of the invention
In order to solve problem above, the present invention provides a kind of special-shaped metal can swollen type moulding process, using secondary swollen type work
Skill is formed by the above moulding process, and can body surface is smooth, not the open defect as caused by mold, to greatly improved
Product quality, for this purpose, the present invention provides a kind of special-shaped metal can swollen type moulding process, the specific steps are as follows:
1) need to print tinplate aniseed according to required processing metal can；
2) aniseed printed handle at circle after being cut into small tablet, cylinder is formed by welding later, after the completion of welding
Weld seam coating is carried out according to actual needs, later dries weld seam coating；
3) carry out swollen type for the first time using corresponding swollen pattern tool according to the case where required molding special-shaped metal can, swollen pattern tool by
The gaps such as the swollen pattern tool of respective numbers were composed around tank body center line one week, were formed after the completion of swollen type for the first time swollen for the first time
Type tank body after molding forms tank surface and has nicking defect, and the shoulder of tank mouth has pit defect；
4) mold is rotated into respective angles, makes smooth position of the die clearance after can body for the first time swollen type, due to swollen for the first time
Tank body height reduces corresponding height after type molding, then mold is vertically moved to mold when highly making second of swollen type accordingly
Shoulder be just overlapped with can body shoulder after swollen type for the first time, after completing two above operation, carry out second of swollen type and eliminate the
The vertical line and shoulder pit defect of can body, can body become smooth after primary swollen type；
5) tank mouth flange is carried out to second of swollen type tank body after molding and capping handles to obtain required special-shaped metal can.
Further improvement of the present invention, weld seam coating is external coating or inside and outside equal coating, coating in weld seam in step 2
Determined according to metal can actual operation requirements, some metal cans do not need interior coating.
Further improvement of the present invention, swollen pattern tool is whole to be composed of 16 pieces of swollen pattern tools, applicant's specific implementation
It is middle to be combined into swollen pattern tool entirety using 16 pieces of swollen pattern tools.
Further improvement of the present invention, swollen pattern tool rotates integrally 12.5 degree in step 4, makes die clearance in can body the
Smooth position after primary swollen type, can body height reduces 8.5mm after swollen type for the first time, longitudinally moves mold before second of swollen type
Dynamic 8.5mm, so that the shoulder of mold is just overlapped with can body shoulder after swollen type for the first time when second of swollen type, the application exists
It gets application in actual production, mold rotation is in production with upper angle and the mobile above distance.
A kind of special-shaped swollen type moulding process of metal can of the present invention, using secondary swollen type technique, specifically: printing tinplate is big
Material → cutting printing aniseed is dried at outer (interior) coating of (interior) coating → weld seam outside small tablet → small tablet Cheng Yuan → welding → weld seam
It is dry → for the first time swollen type → mold rotate by a certain angle, mold longitudinal movement certain distance → second of swollen type → tank mouth flange →
Capping, wherein mold rotation angle is determined by mold block number, and mold longitudinal movement distance is determined by can body height.By above at
The tank body of type technological forming, can body surface is smooth, not the open defect as caused by mold.

Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
The present invention provides a kind of special-shaped swollen type moulding process of metal can, using secondary swollen type technique, by the above moulding process at
Type, can body surface is smooth, not the open defect as caused by mold, so that product quality greatly improved.
A kind of swollen type moulding process of special-shaped metal can of the present invention, the specific steps are as follows:
1) need to print tinplate aniseed according to required processing metal can；
2) aniseed printed handle at circle after being cut into small tablet, cylinder is formed by welding later, after the completion of welding
Carry out according to actual needs outer (interior) coating of weld seam (explanation: coating is determined according to metal can actual operation requirements in weld seam, some
Metal can does not need interior coating), weld seam coating is dried later；
3) first is carried out using the swollen pattern tool of correspondence as depicted in figs. 1 and 2 according to the case where required molding special-shaped metal can
Secondary swollen type, swollen pattern tool is whole to be composed of 16 pieces of swollen pattern tools, and swollen pattern tool is by gaps such as the swollen pattern tools of respective numbers
It was composed around tank body center line one week, after forming first time as shown in Figures 2 and 3 swollen type molding after the completion of swollen type for the first time
Tank body, due to swollen pattern tool mold in metal jug forming it is two pieces adjacent between have certain gap, this is resulted in the
After primary swollen type, semi-finished product can body surface has nicking defect, and the shoulder of tank mouth has pit defect, does not meet can body
Appearance requirement；
4) mold is rotated 12.5 degree, makes smooth position of the die clearance after can body for the first time swollen type, due to first time swollen type
Tank body height after molding reduces 8.5mm, then mold is vertically moved 8.5mm, so that the shoulder of mold is rigid when second of swollen type
Good and can body shoulder coincidence after swollen type for the first time after completing two above operation, carries out second of swollen type elimination swollen type for the first time
The vertical line of can body and shoulder pit defect afterwards, can body become smooth as shown in Figure 5；
5) tank mouth flange is carried out to second of swollen type tank body after molding, tank body after processing as shown in fig. 6, carry out capping processing again
Obtain the special-shaped metal can as needed for Fig. 7.
The above described is only a preferred embodiment of the present invention, being not the limit for making any other form to the present invention
System, and made any modification or equivalent variations according to the technical essence of the invention, still fall within present invention model claimed
It encloses.
