Description

Technical Field

[0001] The utility model relates to the technical field of rubber seal processing, in particular to a punching device for rubber seals. Background Technique

[0002] A rubber seal is a material or part that prevents the leakage of fluids or solid particles from adjacent joint surfaces and prevents the intrusion of external impurities such as dust and moisture into the internal parts of machinery and equipment. The storage room temperature of rubber seals is preferably below 30°C to avoid high-temperature aging of the seals. The production of rubber seals is carried out by punching rubber raw materials with a punching device.

[0003] After retrieval, the patent with the publication number CN219788620U discloses a punching device for rubber seals. By setting a first annular cutter and a second annular cutter, the rubber raw material is punched into two seals with different shapes at one time. However, this device has the same disadvantages as the existing rubber part punching devices: the device has only one station. When punching, workers need to first place the rubber raw material on the bottom die, and then wait for the punching to be completed before taking away the punched seals. However, placing and taking rubber parts takes a relatively long time, affecting the punching efficiency. Secondly, the top punching device and the bottom die cannot be replaced, and rubber seals of different sizes and types cannot be punched, resulting in poor versatility and flexibility. Therefore, further improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a punching device for rubber seals.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A punching device for rubber seals includes a workbench and multiple groups of punching components.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0022] As Figures 1-4 shown, it relates to a punching device for rubber seals, including a workbench 1 and multiple sets of punching assemblies. Each set of punching assemblies includes two bottom dies 3 and a top punch die 8. The bottom ends of the two bottom dies 3 in each set are commonly fixed with a support plate 2. A servo motor 4 is fixed on the lower surface of the workbench 1. The top output shaft of the servo motor 4 passes through the workbench 1 and is fixedly connected with a mounting assembly 5. The support plate 2 is fixedly connected with the output shaft of the servo motor 4 through the mounting assembly 5. An L-shaped support frame 6 is fixed on the upper surface side of the workbench 1. A cylinder 7 is fixed at the top end of the L-shaped support frame 6. A clamping assembly 9 is fixed at the bottom of the telescopic end of the cylinder 7. Each top punch die 8 is fixedly connected with the telescopic end of the cylinder 7 through the clamping assembly 9.

[0023] The mounting assembly 5 includes a top plate 51 fixed at the top end of the output shaft of the servo motor 4. A screw 52 is fixed on the upper surface of the top plate 51. A perforation 21 is formed in the middle of the support plate 2. The top end of the screw 52 passes through the perforation 21 and is rotatably connected with a nut on the surface.

[0024] When installing the support plate 2, pass the screw 52 through the perforation 21 in the middle of the support plate 2, and then screw on the nut on the surface of the screw 52.

[0025] A plug rod 53 is fixed on the upper surface side of the top plate 51. A jack 22 for inserting the plug rod 53 is formed on the lower surface of the support plate 2.

[0026] When installing the support plate 2, the positioning of the support plate 2 can be achieved by inserting the insertion rod 53 into the insertion hole 22, and at this time, the support plate 2 can be driven to rotate by the servo motor 4.

[0027] The clamping component 9 includes a connecting block 91 fixed to the telescopic end of the air cylinder 7. Grooves 92 are formed on both sides of the connecting block 91. A spring 93 is fixedly connected to the inner side wall of the groove 92, and the other end of the spring 93 is fixedly connected to a clamping rod 94. An installation sleeve 81 is fixed in the middle of the upper surface of the punching die 8. The connecting block 91 can be inserted into the interior of the installation sleeve 81, and clamping holes 82 for inserting the clamping rod 94 are formed on both sides of the installation sleeve 81.

[0028] When the connecting block 91 is inserted into the interior of the installation sleeve 81, the spring 93 will squeeze the clamping rod 94 to insert into the interior of the clamping hole 82, thereby realizing the fixed connection between the connecting block 91 and the installation sleeve 81, and thus realizing the fixed connection between the punching die 8 and the telescopic end of the air cylinder 7. When disassembling the punching die 8, after squeezing the clamping rod 94 to disengage from the clamping hole 82, the installation sleeve 81 can be pulled out from the surface of the connecting block 91.

[0029] The end of the clamping rod 94 away from the spring 93 is designed with a round head. By designing the clamping rod 94 into a round head, when the clamping rod 94 is squeezed and retracted into the groove 92, the clamping hole 82 on the installation sleeve 81 is more likely to disengage from the clamping rod 94.

[0030] A double-start switch is provided on the upper surface of the workbench 1, and a controller is installed on the lower surface of the workbench 1. The air cylinder 7, the servo motor 4 and the double-start switch are all electrically connected to the controller.

[0031] In this embodiment, the controller uses an MCST2450CM start controller. After pressing the double-start switch, the air cylinder 7 and the servo motor 4 can be controlled to operate through this controller.

[0032] Working principle: Place the rubber part original on the bottom die 3 on the side close to oneself. Then, after pressing the double-start switch, the servo motor 4 first drives the support plate 2 to rotate 180°, so that the bottom die 3 with the rubber part original rotates to directly below the punching die 8. Then, the air cylinder 7 drives the punching die 8 to descend to achieve punching. When the support plate 2 rotates 180°, the punched bottom die 3 or the bottom die 3 without the rubber part original rotates to the side close to the worker. Therefore, during the punching process, the worker can take away the punched rubber part and place a new rubber part original to prepare for the next punching, realizing double-station punching. The time for taking and placing the rubber part is saved in the middle, improving the punching efficiency. When punching rubber parts of different sizes and types, the support plate 2 can be disassembled from the top of the servo motor 4, and then the support plate 2 with a different bottom die 3 is replaced. Then, the punching die 8 is disassembled and replaced from the bottom of the air cylinder 7.
