Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0023] Embodiments of the present utility model:

[0024] like Figure 1-Figure 3 As shown, a shearing and punching integrated device includes a base 10, a punching assembly, and a shearing assembly. The base 10 is provided with a punching slot 5 and a shearing slot. The base 10 is cast by cast iron or welded by steel plates. The base 10 has a certain weight to ensure stability during use. At the same time, the device is not a large-scale equipment and is relatively small in size.

[0025] The punching assembly includes a punching cylinder 2, a punching support plate 3, a punching lower die 4, and a punching upper die 15. The punching notch 5 is a C-shaped opening that passes through the front and back, which is convenient for loading and unloading operations and for observation during operation. In other embodiments, it can also be set to a rectangular opening or a circular opening. The punching cylinder 2 is arranged on the upper side of the base 10 and the piston rod of the punching cylinder 2 penetrates the punching notch 5. The punching upper die is connected to the piston rod of the punching cylinder 2 by transmission. The punching upper die 15 includes a die core with a conical head. The punching lower die 4 and the punching upper die are arranged opposite to each other in the up and down directions. The center of the punching lower die 4 is provided with a clearance hole 16 to make way for the punching upper die 15 when it moves downward. The punching support plate 3 is arranged in the punching notch 5 to support the workpiece to be processed. The punching support plate 3 is flush with the upper end surface of the punching lower die 4. When force is applied downward, it can pass through the plate or profile to be processed, thereby punching out a structure of a hole. The punching cylinder 2 is a spring return hydraulic cylinder, that is, a return spring is arranged on the piston, and the principle of this cylinder is prior art.

[0026] The shearing assembly includes a shearing cylinder 11, a movable shearing plate 8, and a fixed shearing plate 6. The movable shearing plate 8 and the fixed shearing plate 6 are staggered in the front-rear direction and can generate shearing force when they move relative to each other. The shearing cylinder 11 is arranged on the upper side of the base 10, and the piston rod of the shearing cylinder 11 is transmission-connected with the movable shearing plate 8, and the movable shearing plate 8 and the fixed shearing plate 6 are both located in the shearing notch.

[0027] The shear notch is a rectangular opening that passes through from front to back. The shear notch is spaced apart from the punching notch 5. The shear notch is provided with a movable shear plate 8 and a fixed shear plate 6. The shear notch is provided with a guide plate 7 for guiding the lifting movement of the movable shear plate 8. The fixed shear plate 6 is connected to the guide plate 7 by bolts.

[0028] The upper part of the fixed shear plate 6 is provided with a V-shaped notch, and the lower part of the movable shear plate 8 is provided with a V-shaped convex part. When cutting a tube, the tube is placed in the V-shaped notch, and the movable shear plate 8 is driven by the shear cylinder 11 to move downward and cut the tube by the shear force between the movable shear plate 8 and the fixed shear plate 6. The shear cylinder 11 is also a spring return hydraulic cylinder, which can be quickly reset upward after processing is completed.

[0029] A support slat 12 is also provided on one side of the base 10. The support slat 12 is horizontally arranged, and its two ends are connected to the base 10 by bolts. A support notch is provided in the middle of the support slat 12, and its angle is consistent with that of the V-shaped notch, but the difference is that the size of the support notch is smaller; the support notch is used to support the workpiece, and the V-shaped notch is used to position it. A slat 13 and a screw 14 are installed on one side of the base 10. The support slat 12 is located below the installation slat 13, and the two are arranged in parallel. The screw 14 is threadedly assembled on the installation slat 13, and the lower end of the screw 14 is an abutment portion, which is used to abut against the workpiece to be processed during operation.
