Wherein, above-described each part the first elastic component 25, the second elastic component 235 and third elastic component 236 are selected as bullet
Spring.
The course of work of the utility model is as follows:
It requires (inner bead or outer crimping) to replace curling mechanism 24 according to the crimping of can first, then puts can
It sets in locating slot 121 and the open end of can is arranged upward, start that lower die 1 is driven to move down.
When lower die 1 moves down, each outer bracer 233 can contact first with can bottom；Second elastic component 235, which starts to be pressurized, to be received
Contracting and lower die 1 is when continuing to move down, connecting plate 232 will drive the outer bracer 233 of each part and slide upwards relative to mounting plate 231, because
Cooperation between first lozenges 2331 and the second lozenges 2341, so that the outer bracer 233 of each part can be directed away from guide pad
The directions of 234 center lines is mobile until the outer bracer 233 of each part is abutted with the inside of can side wall, during this, third elasticity
Part 236 is also pressurized contraction；When the second elastic component 235 is shunk completely and lower die 1 continues to move down, the first elastic component 25 starts
It is pressurized and shrinks, so that the outer bracer 233 of each part abuts stronger with can side wall, and curling mechanism 24 is started relatively
In the sliding downwards of internal model briquetting component 23 until the opening end in contact of curling mechanism 24 and can is to carry out crimping work.
After the completion of curling mechanism 24, upper mold 2 is moved up, at this point, the first elastic component 25, the second elastic component 235 and
Three elastic components 236 start to reset, and during which, can be controlled respectively by the cooperation between the second elastic component 235 and third elastic component 236
The direction of part outer bracer 233 towards close 234 center line of guide pad is mobile to prevent bracer 233 outside each part and carry out inner bead work
The can of work is connected together.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
