[0002] A flange, also known as a flange convex disc or a flange, is a part used for connecting pipes to each other and is used for connecting between pipe ends. During the flange processing, a punching operation is required, so a punching device needs to be used.

[0003] Since a large number of holes need to be punched in the flange, generally multiple punching heads are provided in the existing flange punching devices. Although this method can effectively improve the punching efficiency, currently the punching heads are generally fixed on the punching device, and it is difficult to adjust the distance between the multiple punching heads. Different diameters of flanges require holes to be punched at different positions, resulting in a narrow range of applications for the existing flange punching devices. Summary of the Utility Model

[0004] In order to overcome the above defects, the utility model provides a punching device for flange processing, which solves the problem that it is difficult to adjust the distance between multiple punching heads in the existing flange punching devices and the range of applications is narrow.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A punching device for flange processing, including a top plate, an electric push rod is arranged on the top plate, one end of the electric push rod is fixedly connected with a box body, a worm is rotatably connected to the box body, a worm gear is meshed with the worm, a connecting shaft is fixedly connected to the worm gear, one end of the connecting shaft is fixedly connected with a turntable, four inclined slots are opened on the turntable, four T-shaped punching rods are arranged on the turntable, a cross slot is opened on the box body, and four columns are fixedly connected to the bottom of the top plate, and one ends of the four columns are fixedly connected with a bottom plate.

[0006] As a further scheme of the utility model: A three-jaw self-centering chuck is fixedly connected to the top of the bottom plate, and a storage cylinder is arranged on the three-jaw self-centering chuck.

[0010] As a further solution of the present utility model: The box body is located at the top of the storage cylinder, and all four T-shaped punching rods are slidably connected to the box body.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For this flange processing punching device, by setting the worm, worm wheel, inclined groove, T-shaped punching rod and cross groove, when it is necessary to change the distance between the four T-shaped punching rods, rotate the turning handle to drive the worm, worm wheel, connecting shaft, turntable and inclined groove to rotate. Under the guiding action of the inclined groove, the T-shaped punching rod cooperates with the limiting action of the cross groove, so that the four T-shaped punching rods approach or move away from each other, thereby changing the distance between the four T-shaped punching rods. By repeating the punching operation again, holes with different distances can be punched, and it can be adjusted according to the flange body with different diameters, improving the versatility of the device.

[0013] 2. For this flange processing punching device, by setting the baffle, screw and storage cylinder, when the T-shaped punching rod contacts the flange body, the flange body can be punched.

[0020] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0021] As Figures 1-5 shown, the present utility model provides a technical solution: a punching device for flange processing, including a top plate 1, an electric push rod 4 is arranged on the top plate 1, one end of the electric push rod 4 is fixedly connected with a box body 5, a worm 9 is rotatably connected to the box body 5. Due to the presence of the worm 9, the worm 9 cooperates with a worm gear 11 and has a self-locking function, which can lock the distance between the T-shaped punching rods 15 and improve the processing stability. One end of the worm 9 is fixedly connected with a turning handle 10. Due to the presence of the turning handle 10, the turning handle 10 facilitates the staff to rotate the worm 9, thereby improving the operation convenience. Four T-shaped punching rods 15 are evenly distributed on the turntable 12.

[0022] The worm 9 meshes with the worm gear 11. A connecting shaft 13 is fixedly connected to the worm gear 11. One end of the connecting shaft 13 is fixedly connected with a turntable 12. Four inclined slots 14 are formed in the turntable 12. A flange body 8 is arranged inside a storage cylinder 7, and a die plate 19 is fixedly connected inside the storage cylinder 7.
