Description

Technical Field

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

[0002] A sealing diaphragm sheet is a thin film used for isolation, sealing and pressure transmission. It is usually made of materials such as metal, rubber, plastic, etc., and has good elasticity, corrosion resistance and high temperature resistance. Some diaphragm sheets need to be punched during use.

[0003] In the prior art, a punching device for producing a sealing diaphragm sheet proposed in the publication number CN220279869U includes a base. An installation seat is arranged on the top of the base. A connecting groove is opened on the top of the installation seat. An air supply ring is embedded at the inner wall edge of the connecting groove. A plurality of air outlets are opened on the inner wall of the air supply ring. Both ends of the air supply ring are hermetically communicated with an air inlet pipe. Connectors are arranged at the ends of the two air inlet pipes through the installation seat. A diaphragm sheet is arranged inside the connecting groove. Two driving mechanisms are arranged on the top of the base. The beneficial effect of the utility model is that when a user moves the moving rod, the damping rod will touch the diaphragm sheet and then fix the diaphragm sheet. When the damping rod contracts, it will not affect the downward movement of the stepping motor, and at the same time, the diaphragm sheet can be fixed. After the user finishes drilling, air is sent into the air supply ring through the air inlet pipe connected externally, and then the air supply ring discharges air through the air outlets so as to blow the debris in the installation seat into the circular groove and discharge it from the device.

[0004] After the application fixes and punches the diaphragm sheet, at this time, an external air inlet pipe can be communicated with the air inlet pipe of the device, and the air supply ring discharges air through the air outlets, so as to blow the debris into the circular groove and discharge it from the device. However, this application needs to connect an external air pipe to the device, which results in a certain amount of time being consumed for connecting the pipeline and detecting its air tightness during installation, thus affecting the progress of punching the sealing diaphragm sheet.

[0025] Refer to Figures 1-5 , a punching device for producing a sealing diaphragm disclosed by the present utility model includes a base 1, a stamping table 2 is fixedly connected to the middle of the top side of the base 1, an annular groove 3 is opened on the top side of the stamping table 2, an avoidance hole 4 is opened in the middle of the top side of the stamping table 2, a transfer groove 5 is opened on the inner bottom side of the stamping table 2, the transfer groove 5 is communicated with the avoidance hole 4, a discharge groove 6 is opened on the outer peripheral wall of the stamping table 2, the discharge groove 6 is communicated with the transfer groove 5, an air injection component 7 is connected to the outer peripheral wall of the stamping table 2, and a stamping component 8 is arranged above the stamping table 2.

[0026] In this embodiment, when in use, at this time, the diaphragm is placed on the stamping table 2, and the edge is clamped in the arranged annular groove 3, so as to achieve the effect of preliminary positioning. Subsequently, the diaphragm is stamped by the stamping component 8. Then, while the stamping component 8 is stamping, air will be injected into the transfer groove 5 through the air injection component 7. The avoidance hole 4 is used for the waste chips after stamping to be discharged into the transfer hole. At the same time, the waste chips are discharged from the discharge groove 6 through the injection of air by the air injection component 7, so as to achieve the effect of quickly removing the waste chips.

[0027] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the air injection component 7 includes two support plates 9, the two support plates 9 are respectively fixedly installed at both ends of the top side of the base 1, sliding grooves 10 are opened on the sides of the two support plates 9 close to each other, a push plate 11 is slidably connected between the two sliding grooves 10, cavity covers 12 are fixedly connected to the top side of the base 1 in the two sliding grooves 10, a piston piece 13 is slidably connected to the inner top side of the cavity cover 12, a piston rod 14 is fixedly connected to the top side of the piston piece 13, the top end of the piston rod 14 extends upward and is fixedly connected to the bottom side of the push plate 11, and the piston rod 14 is slidably connected to the cavity cover 12.

[0028] In this embodiment, the provided support plate 9 is used to support the driving member. The provided chute 10 allows both ends of the push plate 11 to be slidably connected to the two chutes 10 respectively, enabling the push plate 11 to slide between the two support plates 9. Subsequently, the piston rod 14 can be driven to move up and down. When the push plate 11 moves downward, it will drive the piston rod 14 to move downward, and then drive the piston piece 13 to move downward in the cavity cover 12, thereby conveying the air in the cavity cover 12 into the transfer groove 5, blowing the punching debris in the transfer groove 5 towards the discharge groove 6, and then sending out the waste chips for easy cleaning.

[0029] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, an air injection pipe 15 is connected to the side of the cavity cover 12. The air injection pipe 15 is arranged in an arc shape, and the end of the air injection pipe 15 extends into the punching table 2 and is communicated with the transfer groove 5.

[0030] In this embodiment, when the air in the cavity cover 12 is conveyed outwards, the air injection pipe 15 will be used as a transmission component, enabling the air to enter the air injection pipe 15, and then being conveyed from the air injection pipe 15 into the transfer groove 5. Then, the punching debris falling into the transfer groove 5 is blown towards the discharge groove 6 through air injection, achieving the effect of facilitating the cleaning of the debris.

[0033] In a further preferred embodiment of the present utility model, as Figure 5 shown, the middle part of the bottom side of the push plate 11 is fixedly connected with a punch 19. The outer peripheral wall of the punch 19 is slidably connected with an annular frame 20. A downward pressure spring 21 is connected between the top side of the annular frame 20 and the bottom side of the push plate 11.

[0034] In this embodiment, when the hydraulic rod 18 drives the push plate 11 to descend, the punch 19 will be driven to descend. When the punch 19 reaches the diaphragm, the bottom side of the annular frame 20 will press on the diaphragm, thereby achieving the positioning effect. The provided annular frame 20 can completely enclose and position the periphery of the diaphragm during punching by the punch 19, preventing the diaphragm from deforming when the punch 19 punches, thus affecting the production quality of the diaphragm. When the punch 19 starts punching the diaphragm, the waste chips of the diaphragm during punching are pushed from the avoidance groove into the transfer groove 5, and at the same time, the piston rod 14 and the piston piece 13 will be driven to perform a piston motion, and then the waste chips are blown out into the discharge groove 6 by injecting air. When the hydraulic rod 18 moves upward, the annular frame 20 and the piston piece 13 will be driven to move upward, so that the air in the cavity cover 12 is inhaled through the air injection pipe 15, and at the same time, the return spring will drive the annular frame 20 to return to its original position.
