[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a punching device for rubber products includes a punching device main body 1. A punching lower die 2 is fixedly installed on the working platform of the punching device main body 1. An installation block 3 is fixedly installed at the front end of the punching device main body 1. A fixing component 4 is movably installed on the installation block 3. The fixing component 4 is composed of a connecting column 10, a square rod 11, a fixing spring 12, a connecting plate 13, an annular plate 14, a telescopic plate 16, an inner arc plate 17 and an outer arc plate 18. The square rod 11 is fixedly installed inside the connecting column 10. The fixing spring 12 is sleeved on the square rod 11. The connecting plate 13 is fixedly installed at the upper end of the connecting column 10. The annular plate 14 is fixedly installed at the inner end of the connecting plate 13. There are several telescopic plates 16 and they are all movably installed on the annular plate 14. The inner arc plate 17 is fixedly installed at the inner end of the telescopic plate 16. The outer arc plate 18 is fixedly installed at the outer end of the telescopic plate 16. When punching a rubber gasket, the annular plate 14 on the fixing component 4 can be moved upward first, so that the annular plate 14 is disengaged from the punching lower die 2. Then, the rubber gasket is placed on the upper end of the punching lower die 2, and at the same time, the position of the rubber gasket to be punched is located directly above the material discharge hole 8. Then, the telescopic plate 16, the inner arc plate 17 and the outer arc plate 18 are pushed inward, so that the inner arc plate 17 moves above the rubber gasket. Then, the annular plate 14 is released. At this time, under the elastic force of the fixing spring 12, the annular plate 14 will move downward, and finally the inner arc plate 17 will press on the rubber gasket, and at this time the rubber gasket is fixed. Then, the air cylinder 6 can be started, so that the punching upper die 7 is pushed downward, and finally the punching upper die 7 will complete the punching of the rubber gasket. By setting the installation block 3 at the front end of the punching device main body 1 and setting the fixing component 4 on the installation block 3 and making them cooperate with each other, the fixing component 4 can not only fix the rubber gasket with regular shape, but also fix the rubber gasket with irregular shape, so that the versatility of the punching device is better.

[0021] Furthermore, a material discharge groove is formed on the working platform of the punching device main body 1. A waste material hopper 5 is placed below the material discharge groove on the punching device main body 1. An air cylinder 6 is fixedly installed on the punching device main body 1. A punching upper die 7 is fixedly installed on the telescopic rod of the air cylinder 6. The punching lower die 2 is located below the punching upper die 7. A material discharge hole 8 is formed on the punching lower die 2. When punching, the telescopic rod of the air cylinder 6 will push the punching upper die 7 downward, so that the punching upper die 7 and the punching lower die 2 can cooperate to complete the punching of the rubber gasket, and the waste material punched down will fall into the waste material hopper 5 through the material discharge hole 8 and the material discharge groove formed on the working platform.

[0022] Furthermore, a square hole 9 is formed in the mounting block 3, and the square hole 9 penetrates the mounting block 3 up and down. A guide rail groove 19 is formed in the connecting column 10 on the fixing assembly 4. The connecting column 10 is movably sleeved on the mounting block 3 through the guide rail groove 19. A square rod 11 is fixedly installed in the guide rail groove 19, and the square rod 11 simultaneously passes through the square hole 9 formed in the mounting block 3. A fixing spring 12 is located below the mounting block 3. Both the connecting plate 13 and the annular plate 14 are located above the punching lower die 2. A plurality of through grooves 15 are formed in the annular plate 14, and the through grooves 15 penetrate the annular plate 14 inside and outside. A telescopic plate 16 is movably installed in the through groove 15. An inner arc plate 17 is located inside the annular plate 14, and an outer arc plate 18 is located outside the annular plate 14. When it is necessary to move the annular plate 14 upward so that the annular plate 14 is separated from the punching lower die 2, the connecting column 10 can be pushed upward. At this time, the square rod 11 will move upward in the square hole 9, and the fixing spring 12 will be compressed by the connecting column 10 and the mounting block 3. During the upward movement of the connecting column 10, it will drive the annular plate 14 to move upward through the connecting plate 13. The telescopic plate 16 can slide inside and outside in the through groove 15. After the rubber gasket is placed on the upper end of the punching lower die 2, moving the telescopic plate 16 can adjust the position of the inner arc plate 17. When the inner arc plate 17 is above the rubber gasket, if the connecting column 10 is released at this time, under the elastic force of the fixing spring 12, the inner arc plate 17 can press on the rubber gasket, thereby fixing the rubber gasket on the upper end of the punching lower die 2.
