It is provided with the 6th actuator 704 on first idler wheel 701 or the second idler wheel 702, is driven by the 6th actuator 704 It moves first idler wheel 701 or the second idler wheel 702 is rolled.

It is connected between 6th actuator 704 and first idler wheel 701 or the second idler wheel 702 by train of reduction gears 705.

In the present embodiment, by the way that coaming plate raw material to be arranged on the second idler wheel 702 of lower section, pass through the 5th driving Part 703 drives the first idler wheel 701 to move vertically downwards, clamps to coaming plate raw material, and then is driven by the 6th actuator 704 First idler wheel 701 rolls, by the coaming plate 1 of coaming plate Raw material processing camber；

The first idler wheel 701 and the second idler wheel 702 can be not provided with into the structure to pressure up and down simultaneously, can also be left and right to pressure etc. Mode, the 5th actuator 703, which can be set, also can be set on the first idler wheel 701 on the second idler wheel 702, the 6th actuator 704 can be set and also be can be set on the second idler wheel 702 on the first idler wheel 701；6th actuator 704 is to the second idler wheel 702 structure that can also be slowed down using other of slowing down.

By the way that rounding mechanism 7 is arranged, the rounding mechanism 7 includes the first idler wheel 701 and the second idler wheel 702, by that will enclose Board raw material is arranged between the rollers 27 and 28, drives the first idler wheel 701 that the coaming plate raw material is pressed on second idler wheel 702 On, it is rolled by the first idler wheel 701 of driving or the second idler wheel 702, circular arc sizing is carried out to coaming plate raw material；The coaming plate is former Material raw sheet i.e. round as a ball without rounding mechanism 7, the raw sheet do not have arcuate shape, the coaming plate 1 of round as a ball rear camber.

Squeeze bound edge process:

When work, coaming plate raw material is arranged first and carries out in rounding mechanism 7 round as a ball, forms the coaming plate 1 of arc, this is enclosed Plate 1 is fixed on the coaming plate fixed mechanism 3, and side plate 2 is then fixed on to the side of coaming plate 1, starts the bending mechanism 6, Folding ear 201 on the side plate 2 is subjected to bending, finally starts pressing mechanism 4, squeezes side plate 2 and coaming plate 1, it is complete to squeeze bound edge At.

First actuator 402, the second actuator 6011, third actuator 6021, fourth drive member 303 in the present embodiment It include cylinder or piston-type hydro compressing cylinder with the 5th actuator 703, it can be that cylinder is also possible to piston-type hydro compressing cylinder etc. Pressing mechanism 4 is set to carry out the actuator of same direction movement, same direction movement moves in vertical direction or in transverse direction Direction movement；Oil storage barrel is additionally provided with using piston-type hydro compressing cylinder the case where；6th actuator 704 is including stepper motor etc. The structure that idler wheel can be made to be rolled.

In addition, coaming plate fixed mechanism 3, pressing mechanism 4 and rounding mechanism 7 can be controlled by numerical control, i.e., first drives Moving part 402, the second actuator 6011, third actuator 6021, fourth drive member 303 and the 5th actuator 703 can pass through number The distance of control control piston rod movement, the 6th actuator 704 can control the quantity of stepper motor stepping angle by numerical control, in turn Control the rotation angle of idler wheel；Wherein it is possible in setting coaming plate fixed mechanism 3, the workbench of pressing mechanism 4 and rounding mechanism 7 Upper setting upper spider, upper spider squeeze the mechanism in bound edge special plane to the spiral case and protect, be arranged on upper spider and touch Shield operating case, coaming plate fixed mechanism 3, pressing mechanism 4 and rounding mechanism 7 in upper spider are counted by the touch screen operation box Control operation.
