The main wheel set (42) then drives the second chassis (431) to slide backward, so that the upper and lower second pressing wheels (434) can position the two wings of the steel plate on the other side of the pressing section steel. , in this way, one pre-arching mechanism (4) cooperates with the two shaping mechanisms (2) to form a three-point pressing state, so that it can pre-arch the profiled steel wheel and repeatedly adjust the output shaft of the power cylinder (10) in small amounts. The amount of extension of the end (101) is formed into an arc through repeated pressure back and forth, allowing the section steel to gradually bend to the required arc curvature.

It can be seen from the above actions that the front end of the screw unit (12) corresponds to the bearing seat (14) of the machine (1), forming a straight section without screw teeth, which mainly provides the screw unit (12) with the ability to The pre-arch mechanism (4) screwed at the end is pulled forward to achieve the effect of pre-arch.
