Description

Technical Field

[0001] The utility model relates to the technical field of gasket processing equipment, in particular to a punching device for producing sealing gaskets. Background Technique

[0002] The rubber sealing gasket has properties such as oil resistance, acid and alkali resistance, cold and heat resistance, and aging resistance. It is made by processes such as cutting, stamping or cutting, and is used for the sealing connection between pipes, and the sealing connection between machine parts of machinery and equipment. When processing the sealing gasket, it is usually necessary to cut and punch it.

[0003] By searching for a punching device for producing sealing gaskets with the publication number CN208495521U, a cooling pipe is wound outside the hydraulic cylinder. When the device operates outdoors in a high-temperature environment for a long time and the temperature of the hydraulic oil in the hydraulic cylinder rises, the self-priming pump is turned on. The self-priming pump will quickly circulate the cooling water in the water tank through the cooling pipe, thereby reducing the temperature of the hydraulic cylinder body and avoiding machine failure and punching failure caused by overheating of the hydraulic oil in the hydraulic cylinder.

[0004] However, when the device punches the sealing gasket, it is relatively cumbersome and not convenient for simultaneous center punching and cutting operations, thereby reducing the processing efficiency of the rubber sealing gasket. Therefore, improvements are needed for existing problems. Summary of the Invention

[0005] In view of the above situation, in order to overcome the current technical defects, the utility model provides a punching device for producing sealing gaskets that is easy to use. Through this device, the sealing gasket can be integrally cut and punched into shape, improving the processing efficiency of the sealing gasket production.

[0006] The technical solution adopted by the utility model is as follows: The punching device for producing sealing gaskets proposed by the present invention includes a base, a support frame, a lifting frame and a punching and forming assembly. The support frame is arranged on the base. The lifting frame is slidably arranged on the support frame and is located above the base. Two ends of the inner top wall of the support frame are symmetrically provided with tension springs. The lower ends of the tension springs are connected to the upper end of the lifting frame. A punching die base is installed on the base through bolts. The punching and forming assembly is installed on the lifting frame and corresponds to the punching die base. A press is arranged on the top of the support frame, and the output shaft of the press corresponds to the middle part of the lifting frame.

[0007] For the convenience of cutting and punching the rubber sealing ring, the punching and forming assembly includes a punching sleeve, a punching head and a pressure plate. The punching sleeve is installed in the middle of the bottom wall of the lifting frame. The punching head is installed on the lifting frame and is located inside the punching sleeve. The punching head and the punching sleeve are concentrically arranged. The two ends of the lifting frame are slidably provided with pressure rods. The pressure plate is installed at the lower end of the pressure rods. The pressure plate corresponds to the punching die base. A fixing cap is provided at the upper end of the pressure rod. A support spring is sleeved on the pressure rod. The upper and lower ends of the support spring are respectively connected to the lifting frame and the fixing cap.

[0008] For the convenience of cleaning and collecting the blanking during punching, a punching groove adapted to the punching head is provided in the middle of the punching die base. A ejecting block is slidably arranged in the punching groove. A telescopic spring is provided between the ejecting block and the bottom of the punching groove.

[0009] The beneficial effects achieved by the present utility model with the above structure are as follows: The punching device for producing sealing gaskets provided by this solution has the following advantages: The punching and forming assembly provided can cut the rubber sealing gasket synchronously when punching it. The punching groove, the ejecting block and the telescopic spring can cooperate with the punching head to eject the blanking when punching the rubber sealing gasket, so as to facilitate collection and cleaning.

[0017] As Figure 1 、 Figure 2 and Figure 3 shown, the technical solution adopted by the present utility model is as follows: The punching device for producing sealing gaskets proposed by the present invention includes a base 1, a support frame 2, a lifting frame 3 and a punching and forming assembly 4. The support frame 2 is arranged on the base 1. The lifting frame 3 is slidably arranged on the support frame 2 and is located above the base 1. A punching die base 5 is installed on the base 1 by bolts. The punching and forming assembly 4 is installed on the lifting frame 3 and corresponds to the punching die base 5. A press 6 is arranged at the top of the support frame 2, and the output shaft of the press 6 corresponds to the middle part of the lifting frame 3. Two ends of the inner top wall of the support frame 2 are symmetrically provided with tension springs 7, and the lower ends of the tension springs 7 are connected to the upper ends of the lifting frame 3. The punching and forming assembly 4 includes a punching sleeve 8, a punching head 9 and a pressure plate 10. The punching sleeve 8 is installed in the middle of the lower bottom wall of the lifting frame 3. The punching head 9 is installed on the lifting frame 3 and is located inside the punching sleeve 8. The punching head 9 and the punching sleeve 8 are concentrically arranged. Pressing rods 11 are slidably arranged at both ends of the lifting frame 3. The pressure plate 10 is installed at the lower ends of the pressing rods 11. The pressure plate 10 corresponds to the punching die base 5. Fixing caps 12 are arranged at the upper ends of the pressing rods 11. Support springs 13 are sleeved on the pressing rods 11, and the upper and lower ends of the support springs 13 are respectively connected to the lifting frame 3 and the fixing caps 12.

[0018] As Figure 2 shown, a punching groove 14 adapted to the punching head 9 is arranged in the middle of the punching die base 5. A ejector block 15 is slidably arranged in the punching groove 14, and a telescopic spring 16 is arranged between the ejector block 15 and the bottom of the punching groove 14.

[0019] During specific use, place the rubber gasket to be punched and formed on the stamping die base 5, start the press 6 to drive the lifting frame 3 to move downward, so that the lifting frame 3 drives the punching sleeve 8 and the punching head 9 to move downward accordingly. When the lifting frame 3 moves downward, the pressure plate 10 first compresses the rubber gasket. Under the support of the support spring 13, the punching sleeve 8 and the punching head 9 cut the outer shape and punch holes in the rubber gasket. The punching head 9 then performs blanking on the punching groove 14 in cooperation with the punching groove 14. After stamping is completed, the output shaft of the press 6 moves upward accordingly, and the tension spring 7 resets to drive the lifting frame 3 to move upward, so that the punching sleeve 8 and the punching head 9 move upward accordingly;

[0020] When the punching head 9 cooperates with the stamping die base 5 to punch the rubber gasket, the ejector block 15 moves into the punching groove 14 along with the downward movement of the punching head 9 for stamping. After stamping is completed, the ejector block 15 then moves the punched blank out of the punching groove 14 under the support of the telescopic spring 16 to facilitate the collection of waste materials.
