弧線下調式卷闆機

該機型結構式為四輥弧線下旋式，上下輥為主傳動，通過減速機與上下輥連接，為卷制闆材提供扭矩；下輥作垂直升降運動，通過液壓缸内的液壓油作用于活塞而獲得，以便夾緊闆材，以液壓傳動；在下輥的兩側設有側輥并沿着弧線作傾斜運動，實現闆材彎曲。

The machine adopts the four—roller structu re with the upper roller as the main drive．Both upwa rd and downwa rd movement Th rough hyd rauIic moto rs powe red．The lOwer roller makes ve rtial movements and imposes a force on the piston throuah the hyd raulic oil in the hyd raulic cylinder SO as to clamp the plate tight．Side rollers are arranged On the two sides of the lides of the lower roller，and make inclining movement aIona the gulde rail，and provide drive through the screw，the nut，the worm and the lead screw．The adVantage Of the machine is that the preliminary bending and rolling of the top ends 0f the plates can be conducted on the same machine.

四輥弧線下調式卷闆機特點
闆材無須調頭，端部預彎及卷圓可以在同一台設備上進行。
