detailed description

In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode and in conjunction with the accompanying drawings.

A toggle-type flying shear machine adopts an up-and-down symmetrical structure design, and consists of a frame 1, a first toggle 2, a first connecting piece 3, a first push block 4, a first motor 5, a second toggle 6, a first Three toggles 7, the first scissors assembly 8, the first guide beam 9, the second scissors assembly 10, the second guide beam 11, the second motor 12, the second push block 13, the fourth toggle 14, the second connector 15. The fifth toggle lever 16, the sixth toggle lever 17, the first lead screw 18 and the second lead screw 19 are composed. The frame 1 is fixedly installed on the ground. The ear is hinged, the other end of the first toggle 2 is hinged with the lug on the first connecting piece 3, and the two ends of the second toggle 6 are hinged with the lifting lug on the first connecting piece 3 and the first push block 4 respectively, The left and right sides of the first push block 4 are respectively installed in the guide rails on the frame 1, the first push block 4 is screwed with the first leading screw 18, the first motor 5 is fixedly installed on the frame 1, and the first motor 5 The output shaft is connected with the first lead screw 18, the two ends of the third toggle 7 are hinged with the first connecting piece 3 and the lifting lugs on the first scissor assembly 8 respectively, and the first scissor assembly 8 is installed on the first guide beam 9 In the guide groove, the first guide beam 9 and the second guide beam 11 are fixedly installed on the frame 1, the second scissor assembly 10 is installed in the guide groove of the second guide beam 11, and the two ends of the sixth toggle 17 are respectively Hinged with the lifting lugs on the second scissors assembly 10 and the second connector 15, the two ends of the fourth toggle 14 are respectively hinged with the lifting lugs on the second push block 13 and the second connector 15, and the second push block 13 The left and right sides are respectively installed in the guide rails on the frame 1, the second push block 13 is threadedly connected with the second leading screw 19, the second motor 12 is fixedly installed on the frame 1, the output shaft of the second motor 12 is connected with the first Two leading screws 19 are connected, and the two ends of the fifth toggle 16 are hinged with the second connecting piece 15 and the lifting lug on the frame 1 respectively.
