In the utility model, the lifting assembly 40 includes a rotating shaft 41, a driving motor 42 and an eccentric wheel 43. The driving motor 42 can drive the rotating shaft 41 to rotate, drive the eccentric wheel 43 to rotate, and because the eccentric wheel 43 is accommodated in the lifting frame 31, the eccentric wheel 43 can drive the lifting frame 31 to move up and down when rotating, thereby realizing the up and down reciprocating movement of the upper cutter 30. Compared with the cylinder drive method, the embodiment of the utility model adopts the driving motor 42 as the power source, and uses the eccentric wheel 43 to convert the rotary motion of the rotating shaft 41 into the lifting motion of the lifting frame 31, which is helpful to achieve long-term stable shearing. The shearing frequency can be controlled by adjusting the speed of the driving motor 42, which is simple and convenient.

[0040] In the embodiment of the utility model, the mounting frame 10 can be assembled by welding or screwing the first mounting plate 11, the second mounting plate 12 and the guide column 13. The first mounting plate 11 and the second mounting plate 12 are arranged at intervals up and down, and can be strip-shaped, plate-shaped, etc. The guide column 13 is connected between the first mounting plate 11 and the second mounting plate 12. One or more guide columns 13 can be provided as needed. When there are multiple guide columns 13, the multiple guide columns 13 are arranged at intervals along the length direction of the first mounting plate 11.

[0041] The upper cutter 30 and the lower cutter 20 are arranged opposite to each other in the vertical direction. The upper cutter 30 has a second cutting edge facing downward, and the upper cutter 30 has a first cutting edge facing upward. When the first cutting edge and the second cutting edge are aligned, an object such as a metal plate can be cut. The first cutting edge and the second cutting edge can be straight, arc-shaped or other shapes, and can be specifically designed according to the shape of the cut to be sheared.

The limited space can be square. The outer peripheral surface of the eccentric wheel 43 fits the upper and lower inner walls of the limited space. The limited frame is connected to the upper cutter 30 through a connecting rod. When the eccentric wheel 43 rotates, it can drive the limited frame to move up and down, thereby driving the upper cutter 30 to move up and down.

[0044] See also Figure 1 , Figure 2 and Figure 4 In some possible embodiments, the driving motor 42 is disposed on the second mounting plate 12 and is located in the middle position of the second mounting plate 12 .

[0045] In this embodiment, the drive motor 42 is arranged in the middle of the mounting frame 10.

[0051] See also Figure 1 and Figure 4 In some possible embodiments, the upper surface of the first mounting plate 11 adjacent to the discharge side is inclined downward to form a material guiding slope 111 , and the material can slide down through the material guiding slope 111 after being sheared.

[0052] See also Figures 1 to 4 In some possible embodiments, the shearing head 1 also includes a rotary drive assembly 50, which is used to drive the mounting frame 10 to rotate around a vertical axis.

[0053] The rotary drive assembly 50 may be a power device such as an electric motor or a hydraulic rotary motor that can output a rotary motion.

[0054] See also Figure 5 In the second aspect, the utility model also provides a swing shearing device, including a feeding component 2, an edge cutting component 3, a punching component and a shearing head 1, the feeding component 2 is used to convey the metal strip along a first horizontal direction; the edge cutting component 3 is arranged on the discharge side of the feeding component 2, and is used to cut the edge of the metal strip; the punching component is arranged on the discharge side of the edge cutting component 3, and is used to punch holes in the metal strip; the shearing head 1 is arranged on the discharge side of the punching component, and the metal strip passes between the first cutting edge and the second cutting edge.

[0055] In this embodiment, the feeding assembly 2 is used to convey materials along the first horizontal direction to complete the loading of parts. The feeding assembly 2 can be a roller conveyor, a feeding robot, etc. The edge cutting assembly 3 is used to shear the edge of the metal plate. There is no restriction on the shape of the edge shearing, such as Figure 5The V-shaped shearing is shown, but it can also be a fan-shaped or other shape. The punching assembly is used to punch holes in the metal plate, and the shearing head 1 is set at the end to shear the metal plate into a certain length. When the shearing head is working, the rotary drive assembly 50 drives the mounting frame 10 to rotate around the vertical axis to achieve swing shearing.
