[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A punching device for forged flanges, such as Figure 1 - Figure 4As shown, the system includes a base 1, a support frame 2 fixedly connected to the top of the base 1, a slider 3 slidably connected to the inner wall of the support frame 2, a punching mechanism 5 at the bottom of the slider 3, the punching mechanism 5 including a hydraulic cylinder 51, a punch 52 fixedly connected to the telescopic end of the hydraulic cylinder 51, an annular air cylinder 53 fixedly connected to the outer wall of the hydraulic cylinder 51, a one-way valve at the top of the annular air cylinder 53, an annular piston 54 slidably connected to the inner wall of the annular air cylinder 53, a support rod 55 fixedly connected to the bottom of the annular piston 54, the support rod 55 being fixedly connected to the telescopic end of the hydraulic cylinder 51, an air jet head 56 fixedly connected to the bottom of the annular piston 54 via a bellows, and the air jet head 56 being fixedly connected to the telescopic end of the hydraulic cylinder 51, a lead screw 4 for driving the slider 3 to move is provided inside the support frame 2, and a servo motor for driving the lead screw 4 to rotate is provided inside the support frame 2.

[0026] In this embodiment, the slider 3 is moved by rotating the drive screw 4 driven by a servo motor, so as to facilitate the adjustment of the distance from the center of the punching mechanism 5 when punching. The extension and retraction of the hydraulic cylinder 51 drives the punch 52 to sink, so as to facilitate the punching of the corresponding flange. When the punch 52 has finished punching, when the hydraulic cylinder 51 drives the punch 52 to rise, the extension and retraction end of the hydraulic cylinder 51 will drive the support rod 55 to rise and lift the annular piston 54 in the annular air cylinder 53, so that the air in the annular air cylinder 53 is compressed and sprayed out at high speed from the position of the punch 52 and sprayed towards the punching position on the flange, so as to facilitate the removal of chips and avoid the problem that chips accumulate between the punch 52 and the flange, which would increase the resistance of the punch 52 and affect the stamping effect.

[0027] like Figure 3 As shown, preferably, a turntable 6 is rotatably connected to the inner wall of the base 1 for placing the flange. The inner wall of the turntable 6 has a through groove for allowing the punch 52 to sink below the flange during stamping. A gear ring 61 is fixedly sleeved on the outer wall of the turntable 6. A drive wheel 62 is meshed with the outer wall of the gear ring 61. A stepper motor for driving the drive wheel 62 to rotate is fixedly connected inside the base 1.

[0028] In this embodiment, when the flange is punched for the first time and the angle needs to be changed for subsequent punching, the servo motor drives the drive wheel 62 to rotate, and the meshing gear ring 61 drives the turntable 6 to rotate. This facilitates the angle switching of the flange above through the turntable 6, avoiding excessive time spent on calibrating the angle position during continuous punching and improving processing efficiency.

[0029] like Figure 2As shown, preferably, clamping assemblies 7 are respectively provided on both sides of the turntable 6. The clamping assemblies 7 are used to clamp the flange. The clamping assemblies 7 consist of a pressure plate 71, a pressure block 72, and a cylinder 73. The pressure plate 71 is hinged to the top of the base 1. The pressure block 72 is hinged to the end of the pressure plate 71 near the top of the turntable 6. The cylinder 73 is fixedly connected to the top of the base 1 and is used to lift the end of the pressure plate 71 away from the top of the turntable 6. The end of the cylinder 73 that contacts the pressure plate 71 is arc-shaped, and the pressure plate 71 and its corresponding position are provided with grooves.

[0030] In this embodiment, by setting the cylinder 73 to lift one end of the pressure plate 71, the pressure block 72 hinged to the other end of the pressure plate 71 presses against the top of the flange on the turntable 6, thereby improving the stability and accuracy of the flange processing.

[0031] In use, the forging flange punching device of this utility model places the flange to be processed in the center on the top of the turntable 6. Cylinders 73 on both sides of the turntable 6 lift one end of the pressure plate 71, causing the pressure block 72 hinged to the other end of the pressure plate 71 to press against the top of the flange on the turntable 6, thus improving the stability of the flange processing. A servo motor drives the drive screw 4 to rotate, driving the slider 3 to move, facilitating adjustment of the position of the punching mechanism 5 from the center during punching. The hydraulic cylinder 51 extends and retracts, causing the punch 52 to descend, facilitating punching of the corresponding flange. When the punch 52 punches... After the hole is completed, when the hydraulic cylinder 51 drives the punch 52 to rise, the extension end of the hydraulic cylinder 51 will drive the support rod 55 to rise and lift the annular piston 54 in the annular air cylinder 53, so that the air in the annular air cylinder 53 is compressed and sprayed out at high speed from the position of the punch 52 and sprayed towards the punched position on the flange to facilitate the removal of chips. When the flange is punched for the first time and it is necessary to change the angle for subsequent punching, the servo motor drives the drive wheel 62 to rotate, and the meshing gear ring 61 drives the turntable 6 to rotate, so as to facilitate the angle switching of the flange above through the turntable 6.
