[0033] Working principle:

[0034] In the actual working process, rotating the pitch-adjusting hand wheel 3-2 can drive the pitch-adjusting screw 3-1 connected thereto to rotate, and drive another set of pitch-adjusting screws 3-1 to rotate simultaneously through the pitch-adjusting transmission shaft 3-4 and the bevel gear pair 3-5, thereby driving the forming assembly installed therewith to move laterally along the linear guide pair 4, so as to achieve the purpose of adjusting the spacing between the first forming assembly 5 or the second forming assembly 6, and the operation process is simple, fast and convenient;

[0035] In addition, in the actual working process, the above-mentioned driving motor is started to drive the spline shaft 2-5 to rotate, and then drive the active sprocket 2-2 matched with its spline to rotate. Under the action of the transmission chain, the rotating active sprocket 2-2 can drive the lower pressure wheel shaft 5-13 in the first forming component 5 and the second forming component 6 to rotate, and then perform bending and forming operations on the aluminum strip when it is transmitted forward; when the spacing adjustment screw 3-1 in the spacing adjustment component 3 rotates, it can drive the corresponding forming component to move, and when the forming component moves, it can drive the movable mounting seat 2-4 installed thereon to move synchronously. Since the active sprocket 2-2 is rotationally connected with the movable mounting seat 2-4 and the active sprocket 2-2 is splined with the spline shaft 2-5, when the forming component moves, it can ensure that the second transmission pair composed of the active sprocket 2-2, the driven sprocket and the chain in the rotating drive component 2 moves synchronously with the corresponding forming component, and then drive the corresponding lower pressure wheel shafts 5-13 in the forming component to rotate synchronously, so as to achieve the purpose of not affecting the normal operation of the first forming component 5 and the second forming component 6 before and after the spacing adjustment.
