The circular can blank to be formed is placed on a conveying belt of a production line, a cylinder body of the cylinder is fixed on a rack, a push rod of a driving cylinder moves downwards to enable the driving shaft to drive two side plates to move downwards, the distance between the two side plates is small due to the tensile force action of a first reset spring and a second reset spring, the push rod can be inserted into the circular blank conveniently, when the lower ends of the side plates abut against the conveying belt, a pressing block moves downwards relative to the side plates to compress the second reset spring, the two connecting plates move towards two sides under the action of a first guide surface and a second guide surface, the first reset spring is stretched to enable the distance between the two side plates to be increased until the blank is supported to be in an appointed shape, after the driving shaft is driven to reset by the cylinder, the two side plates move towards each other under the action of the first reset spring and the second reset spring, the distance between the.

In the above square can forming device, a limiting plate is fixedly arranged at the lower end of the driving shaft.

The limiting plate is used for providing limit limiting of the maximum forming external tension, so that the consistency of products is improved.

In the above-mentioned one of the square can forming apparatuses, the number of the expansion units is three, and the expansion units are equally spaced on the driving shaft.

The expansion components are conveniently arranged at the upper part, the middle part and the lower part of the tank body, so that the stress is uniform in the blank forming process, and the top and the bottom which are easy to deform irregularly are well limited and controlled.
