Pulleys are sleeved on the two rotating shafts 25, and a transmission belt is connected between the two pulleys. A stamping table 3 is installed on the base 1, and a fixed mold 4 is installed on the stamping table 3. The fixed mold 4 can be disassembled from the stamping table 3, which is convenient for replacing different molds for matching stamping. A guide rod 5 is connected to the side wall of the base 1, and a stamping part 6 is provided on the guide rod 5. The material lifting plate 22 is fitted with the top of the stamping table 3, and the end of the material lifting plate 22 close to the stamping table 3 is a slope structure. The sloped end of the material lifting plate 22 lifts the edge of the circular plate blank, thereby loosening the circular plate blank.

[0029] In this embodiment, when the circular plate blank is punched through the movable mold 8, the tooth plate 62 contacts and meshes with the spur gear 1 26, and the pulley drives the two rotating shafts 25 to rotate synchronously through the transmission belt, causing the spur gear 2 27 to push the spur gear 28 and make the picking plate 22 move away from the punching table 3. After the punching is completed, the spring 210 elastically contracts and drives the picking plate 22 to reset under the limiting action of the slide rod 29, thereby causing the inclined end of the picking plate 22 to lift the edge of the circular plate blank.

[0030] Embodiment 2

[0031] See also Figure 1-7On the basis of the first embodiment, the utility model provides a technical solution: preferably, the stamping part 6 includes a shell cover 61, a tooth plate 62 is connected to one side of the outer wall of the shell cover 61, a guide arm 63 is connected to the outer wall of the shell cover 61, a hydraulic cylinder 64 is connected to the top of the shell cover 61, a gear ring 65 is rotatably connected to the movable end of the hydraulic cylinder 64, a motor 66 is installed on the top of the outer wall of the shell cover 61, a bevel gear 67 is sleeved on the output shaft of the motor 66, the shell cover 61 is slidably connected to the guide rod 5 through the guide arm 63, an adjusting part 7 is installed on the stamping part 6 and includes a mounting block 71, the mounting block 71 is connected to the top of the outer wall of the shell cover 61, a stud 72 is movably penetrated on the mounting block 71, the stud 72 is rotatably connected to the mounting block 71, a limiting rod 73 is connected to the mounting block 71, an adjusting plate 74 is sleeved on the stud 72, the adjusting plate 74 is threadedly connected to the stud 72, and the adjusting plate 74 is threadedly connected to the stud 72. The plate 74 is slidably sleeved on the limit rod 73, and the side of the adjustment plate 74 close to the shell cover 61 is connected to the adjustment arm 75, which is movable and penetrates into the interior of the shell cover 61 and is installed with a triangular clamping arm 76. The end of the stud 72 away from the adjustment plate 74 is sleeved with a bevel gear 2. There are three adjustment parts 7, and the three adjustment parts 7 are mounted around the top of the outer wall of the shell cover 61. The bevel gears 2 in the three adjustment parts 7 are all meshed with the gear ring 65, and the bevel gear 1 67 is meshed with the gear ring 65. The triangular clamping arms 76 in the three adjustment parts 7 clamp the movable mold 8. The cavity of the movable mold 8 is aligned with the fixed mold 4. The outer wall of the movable mold 8 is provided with a clamping groove corresponding to the triangular clamping arm 76. The clamping groove on the movable mold 8 is used for limiting clamping to prevent the movable mold 8 from falling. The top of the guide rod 5 is connected to the crossbeam 9, the outer rod of the hydraulic cylinder 64 is mounted on the top of the crossbeam 9, and the inner rod of the hydraulic cylinder 64 slides through the crossbeam 9.

[0032] In this embodiment, the output shaft of the motor 66 drives the bevel gear 1 67 to rotate the gear ring 65, and synchronously drives the studs 72 on the three bevel gears 2 to rotate, so that the triangular clamp arms 76 on the adjustment arm 75 are close to each other, and then the distance between the three triangular clamp arms 76 is adjusted. The adjustment part 7 can quickly adjust to the appropriate distance to stably clamp the movable mold 8 of different diameters.

[0033] Working principle: the round plate blank is placed on the fixed die 4, the inner rod of the hydraulic cylinder 64 extends to push the shell cover 61 down, and the shell cover 61 falls vertically on the guide rod 5 through the guide arm 63, prompting the movable die 8 to punch the round plate blank. At this time, the fixed die 4 enters the inner wall of the cavity of the movable die 8, prompting the round plate blank to be punched and formed. When the shell cover 61 descends, the tooth plate 62 contacts and meshes with the spur gear 1 26, thereby driving the rotating shaft 25 to rotate through the spur gear 1 26, and the pulley drives the two rotating shafts 25 to rotate synchronously through the transmission belt, and then the spur gear 27 rotates, thereby driving the spur gear 2 8 and make the lifting plate 22 away from the punching table 3. When the movable die 8 completely punches the round plate blank, it will not come into contact with the lifting plate 22. After the punching is completed, when the inner rod of the hydraulic cylinder 64 contracts to make the movable die 8 separate from the fixed die 4, the tooth plate 62 drives the spur gear 26 to reverse and prompts the lifting plate 22 to approach the punching table 3. The spring 210 elastically contracts and drives the lifting plate 22 to reset under the limiting action of the slide bar 29, thereby prompting the inclined end of the lifting plate 22 to lift the edge of the round plate blank, thereby loosening the round plate blank, avoiding the problem of the round plate blank sticking to the mold after punching and making it inconvenient to unload.

[0034] On the other hand, the output shaft of the motor 66 drives the bevel gear 1 67 to rotate, prompting the gear ring 65 to rotate, and synchronously drives the three bevel gears 2 to rotate, thereby causing the three studs 72 to rotate synchronously. At this time, the three adjustment plates 74 approach the shell cover 61 under the limiting action of the limiting rod 73, and drive the triangular clamping arms 76 on the adjustment arms 75 to approach each other, thereby adjusting the distance between the three triangular clamping arms 76. Conversely, when the motor 66 is reversed, the distance between the three triangular clamping arms 76 can be increased. In this way, the clamping diameter between the triangular clamping arms 76 can be quickly adjusted, and the movable mold 8 of the corresponding diameter can be quickly loaded and unloaded, and the clamping groove on the movable mold 8 can be used for limiting clamping to prevent the movable mold 8 from falling. Compared with the prior art, the adjustment portion 7 of this case can be quickly adjusted to a suitable distance to stably clamp the movable molds 8 of different diameters, and also replaces the traditional threaded part installation method, which is more efficient in loading and unloading the movable mold 8 and improving the efficiency of mold replacement.
