Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1-2, which illustrate a preferred embodiment of the present invention.
The embodiment provides a curling machine for a lower cover of an expansion water tank, which comprises a frame 1, wherein a curling platform 10 is fixedly arranged on the left side of the top of the frame 1, a curling inner pressing wheel 4 is fixedly arranged on the right side of the top of the curling platform 10, a hydraulic oil cylinder 11 is arranged on the frame 1 and positioned on the right side of the curling platform 10, a piston rod of the hydraulic oil cylinder 11 is connected with a speed reducer 6, an output shaft of the speed reducer 6 is connected with a curling outer pressing wheel 3, and the driving end of the speed reducer 6 is connected with a driving motor 2;
the hemming outer pressing wheel 3 is a concave wheel, and the wheel width of the hemming inner pressing wheel 4 is matched with the groove width of the hemming outer pressing wheel 3.
Supporting legs 12 are fixedly arranged on the periphery of the bottom of the rack 1.
The frame 1 is provided with a turnover cylinder 8, and a piston rod of the turnover cylinder 8 is hinged with the lower end face of the hemming platform 10.
A table-board cylinder 9 is arranged on the machine frame 1, and a piston rod of the table-board cylinder 9 is hinged with the lower end face of the curling platform 10.
