Description

Technical Field

[0001] The utility model relates to the field of punching devices, and particularly relates to a punching device for silica gel products. Background Technique

[0002] Silica gel is a granular, glassy, porous form of silicon dioxide prepared synthetically from sodium silicate. Silica gel is harder than ordinary household gel-like gelatin and agar. Silica gel products are processed products mainly made of silica gel. After many silica gel products are prepared, they need to be punched, so punching devices are used.

[0003] When the punching device punches a silica gel product, the silica gel is placed on the platform. After the air cylinder is started, the pressing structure is used to press and fix the silica gel, and then the punching operation is carried out with the punch. However, when the existing punching device is in use, although the guide rods and springs are provided in the pressing structure and can form a buffer during the pressing process, the limit blocks above each guide rod need to be installed with screws. In this way, multiple screws need to be operated, which is not convenient for the quick installation and disassembly of the limit blocks, and thus affects the quick replacement of the buffer springs. At the same time, after punching is completed, the waste materials cut off are easily attached to the lower part of the punch, which affects the normal progress of subsequent punching. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a punching device for silica gel products, which can effectively solve the problems in the background technique.

Detailed implementation manner

[0018] 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 the specific implementation manners.

[0019] As Figures 1-4 shown, a punching device for silicone products includes a fixed frame 1. A guide rail 2 is provided on the fixed frame 1, and a slider 3 is installed on the guide rail 2. A lifting seat 4 is connected to the slider 3. A lifting cylinder 5 is installed at the upper end of the fixed frame 1. A placing seat 6 is provided on the fixed frame 1. A blanking hole 7 is opened on the placing seat 6. A punching cylinder 8 and a pressing structure 9 are installed on the lifting seat 4. The lower end of the telescopic shaft of the punching cylinder 8 is connected to a punching component 10. The slider 3 is fixedly connected to the lifting seat 4, and the slider 3 is slidably connected to the guide rail 2. A mounting hole 11 is provided on the lifting seat 4, and the mounting hole 11 is connected to the cylinder shaft of the lifting cylinder 5. A supporting column 12 is provided on the fixed frame 1, and the upper end of the supporting column 12 is connected to the placing seat 6.

[0020] When using the punching device to punch silicone products, the fixed frame 1 is installed on the work station. The silicone products to be punched are placed on the placing seat 6. After starting the lifting cylinder 5, the lifting cylinder 5 drives the lifting seat 4 to descend along the guide rail 2 through the slider 3. When the pressing structure 9 contacts the silicone products and presses and fixes them, the punching cylinder 8 on the lifting seat 4 is started. Under the action of the punching cylinder 8, the punching component 10 suddenly descends, thereby punching the silicone products. The waste materials punched are discharged from the blanking hole 7, and thus the punching work of the silicone products is completed.

[0021] Through the above implementation, the pressing structure 9 includes a U-shaped frame 901, a movable rod 902, a buffer spring 903, a pressing plate 904, a connecting plate 905, a limiting insertion rod 906, a guiding rod 907, and a support spring 908. The U-shaped frame 901 is fixed to the lower end of the lifting seat 4. The movable rod 902 passes through the lower end of the U-shaped frame 901, and the movable rod 902 is fixedly connected to the pressing plate 904. The buffer spring 903 is sleeved on the lower end of the movable rod 902, and the lower end of the buffer spring 903 contacts the pressing plate 904. A circular hole is provided at the upper end of the movable rod 902. The connecting plate 905 is fixedly connected to the limiting insertion rod 906, and the limiting insertion rod 906 passes through the circular hole at the upper end of the movable rod 902. The guiding rod 907 passes through the lower end of the U-shaped frame 901, and the upper end of the guiding rod 907 is threadedly connected to the connecting plate 905. The support spring 908 is sleeved on the guiding rod 907, and the support spring 908 is located between the lower end of the U-shaped frame 901 and the connecting plate 905. By providing the pressing structure 9, the connecting plate 905 and the limiting insertion rod 906 are provided at the upper end of the movable rod 902 and used in cooperation with the guiding rod 907 and the support spring 908. While limiting and preventing the movable rod 902 from falling off, a single guiding rod 907 is used for connection and limitation. Only by operating the guiding rod 907 can the limiting insertion rod 906 be quickly removed to disassemble the movable rod 902, which is convenient for replacing the buffer spring 903. The support spring 908 provides a supporting effect on the connecting plate 905, which can prevent the connecting plate 905 from directly hitting the U-shaped frame 901 when the entire pressing structure 9 moves upward, ensuring the integrity of the relevant structure.

[0022] When punching, as the lifting seat 4 descends, the pressing plate 904 first contacts the silicone product. The lifting seat 4 drives the U-shaped frame 901 to continue descending. Since the pressing plate 904 is limited and no longer descends, the U-shaped frame 901 moves towards the pressing plate 904 and compresses the buffer spring 903 until the silicone product is firmly fixed. During this process, the guiding rod 907 rises relative to the U-shaped frame 901. Then, the punching cylinder 8 is started to perform the punching operation. After punching, the lifting seat 4 rises, the U-shaped frame 901 rises, the buffer spring 903 elongates, and the movable rod 902 drives the connecting plate 905 and the limiting insertion rod 906 to descend relative to the U-shaped frame 901. When the support spring 908 contacts the connecting plate 905, it provides a supporting effect on the connecting plate 905, thereby avoiding the connecting plate 905 from directly hitting the U-shaped frame 901. Then, the entire pressing structure 9 rises and resets. When needed, the guiding rod 907 can be quickly removed, and then after pulling out the limiting insertion rod 906, the movable rod 902 can be disassembled from the U-shaped frame 901, and then the buffer spring 903 can be replaced. The structure is simple and the operation is highly convenient.

[0023] Through the above embodiments, the punching assembly 10 includes a punching plate 1001, a connector 1002, a cavity 1003, a punch 1004, a blow hole 1005 and a one-way valve connector 1006. The punching plate 1001 is fixedly connected to the connector 1002. The cavity 1003 is formed in the punching plate 1001. The blow hole 1005 is formed in the punch 1004. The punch 1004 is fixed on the lower surface of the punching plate 1001. The cavity 1003 is communicated with the blow hole 1005. The one-way valve connector 1006 is installed on the punching plate 1001. By providing the punching assembly 10, the cavity 1003 is provided on the punching plate 1001, and the blow hole 1005 communicated with the cavity 1003 is formed in the punch 1004. The pipeline connection can be carried out by using the one-way valve connector 1006. After punching is completed, the gas blows out from the blow hole 1005 to carry out the blanking work of the waste material, preventing the waste material from adhering to the lower end of the punch 1004 and avoiding affecting the subsequent punching operation.

[0024] When punching, after the punching cylinder 8 operates, the connector 1002 drives the punching plate 1001 to descend. After the punch 1004 contacts the silicone product, the punching operation is carried out until the lower end of the punch 1004 passes through the blanking hole 7. Subsequently, the compressor at the air source is started, and the compressed gas enters the cavity 1003 through the pipeline and the one-way valve connector 1006, and finally blows out from the blow hole 1005. The blown gas can act on the waste material attached to the lower end of the punch 1004 and not falling off, ensuring that the waste material does not adhere to the lower end of the punch 1004 and guaranteeing the normal progress of subsequent punching.
