Description

Technical Field

[0001] This utility model relates to the field of sealing ring cutting technology, and in particular to a sealing ring cutting mechanism. Background Technology

[0002] Sealing rings are precision components that prevent fluid (liquid, gas) leakage and the intrusion of external impurities. Their sealing principle is based on the contact pressure generated by elastic deformation. When installed in a sealing groove, the sealing ring is squeezed and deformed, filling the microscopic gaps on the contact surface to form a sealing barrier. The sealing ring cutting mechanism is the key equipment to achieve precise forming of sealing rings. Its core is to meet the stringent requirements of high-end manufacturing fields for sealing components through the coordinated optimization of mechanical structure, drive system and intelligent control.

[0003] A search revealed Chinese patent publication number CN221818804U, which discloses a cutting device for processing sealing rings. The device includes a cutting machine, a support column fixedly connected to the outer wall of the cutting machine, two sets of fixed plates fixedly connected to the inner wall of the support column, a rotating column rotatably connected to the center of the support column, a connecting seat fixedly connected to the center of the rotating column, a connecting rod rotatably connected to the outer wall of the connecting seat, an arc plate rotatably connected to the top of the connecting rod, a moving block fixedly connected to the bottom end of the arc plate, a guide rail fixedly connected to the inner wall of the support column, and a limit component fixedly connected to the front end of the support column. This invention addresses the need for processing larger sealing ring rubber pads. During the cutting process, the limiting components are first released, and then the rotating column is rotated to make the four sets of arc plates move in all directions, thereby supporting the overall size of the support column. This avoids the need to change the cutting machine to cut larger sealing ring rubber pads. There is also the problem that the metal positioning reference surface will develop dents after long-term use, causing the cumulative positioning error to increase with production time. Currently, detachable wear-resistant pads, such as inlaid ceramic and tungsten steel pads, are used, which can be directly replaced after wear. However, traditional mechanical stamping and cutting results in a high burr rate on the cross-section. Hard tools are prone to deformation and springback when cutting elastic materials. Switching between multiple specifications relies on manual mold adjustment, which cannot meet the high-efficiency production needs of sealing rings of multiple specifications and materials. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cutting mechanism for sealing rings, which aims to improve the problems of high burr rate of cross-section caused by traditional mechanical stamping cutting, easy deformation and springback of hard tools when cutting elastic materials, and reliance on manual mold adjustment for switching between multiple specifications, which cannot meet the high-efficiency production needs of sealing rings of multiple specifications and materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sealing ring cutting mechanism, comprising a fixed frame, a worktable fixedly connected to the upper part of the inner wall of the fixed frame, a fixed block fixedly connected to the left side of the top wall of the worktable, a fixing mechanism installed on the top left side of the fixed frame, the fixing mechanism being used to fix the cutting tool and facilitate replacement, an adjustment mechanism installed on the left side of the top wall of the worktable, the adjustment mechanism being used to adapt to rubber rings of different sizes; the fixing mechanism comprises a fixing frame, the fixing frame being fixedly connected to the top left side of the fixed frame, a hydraulic rod fixedly connected to the left side of the outer wall of the fixing frame, sliding columns fixedly connected to the front and rear sides of the inner wall of the fixing frame, and a slider fixedly connected to the right end of the hydraulic rod.

Multiple clamping components are installed equidistantly on the inner sides of both the slider and the installation block.

[0008] The above technical solution involves installing clamping blocks on the inner sides of both the slider and the mounting block, and installing rubber pads on the outer sides of the clamping blocks.

[0010] The above technical solution involves installing a rubber pad on the outside of the clamping block, placing the laser cutting head inside the rubber pad, and sliding the slider to the right to cooperate with the mounting block to fix the laser cutting head.

[0011] As a further description of the above technical solution: The adjustment mechanism includes a mounting plate, which is fixedly connected at equal intervals to the left side of the top wall of the fixing block. A motor is fixedly connected to the left side of the outer wall of the mounting plate, and a limit component is installed at the output end of the motor.

[0013] As a further description of the above technical solution: The limiting component includes a turntable, which is fixedly connected to the output end of the motor. Multiple sliding grooves are equidistantly provided on the right side of the outer wall of the turntable, and a fixing column is installed in the middle of the right side of the outer wall of the turntable.

[0014] Through the above technical solution, the slide bar slides smoothly on the inner wall of the slide groove, and the sliding of the slide bar further drives the crank, so that the crank can rotate flexibly on the shaft.

[0015] As a further description of the above technical solution: Multiple rotating shafts are equidistantly rotatably connected to the right side of the outer wall of the mounting plate. A crank is rotatably connected to the end of each rotating shaft, and a slide rod is installed at the end of each crank. The slide rod is slidably connected to the inner wall of the slide groove.

[0016] The above technical solution involves multiple sliding rods sliding within the groove and moving towards the center and periphery, placing the sealing ring on the outer wall of the sliding rod, which then expands it to accommodate sealing rings of different diameters, facilitating their cutting.

[0017] As a further description of the above technical solution: A controller is installed on the left side of the outer wall of the fixed frame, and an indicator light is fixedly connected to the left side of the top wall of the controller.

During the rotation of the turntable 4051, the slide rod 406 slides along the inner wall of the slide groove 4052. The sliding of the slide rod 406 drives the crank 404 to rotate. The crank 404 rotates on the rotating shaft 403. This mechanism allows multiple slide rods 406 to slide in the slide groove 4052 and can move towards the center or the periphery. The sealing ring is fitted on the outside of the slide rod 406, and the slide rod 406 opens it to accommodate sealing rings of different diameters, which facilitates the cutting operation. Specifically, the motor 401 rotates to drive the turntable 4051. When the turntable 4051 rotates, it allows the slide rod 406 to slide on the inner wall of the slide groove 4052.

[0029] Working principle: The hydraulic rod 301 pulls the slider 304 through its telescopic movement, allowing the slider 304 to slide smoothly on the outer surface of the sliding column 303. A mounting block 306 is carefully installed in the inner space of the fixed frame 302 to ensure structural stability and functionality. Clamping blocks 3071 are firmly installed on the inner edges of both the slider 304 and the mounting block 306. Soft rubber pads 3072 are attached to the outer sides of these clamping blocks 3071. The laser cutting head 305 is securely placed inside the rubber pads 3072, ensuring it does not shift during operation. When the slider 304 slides to the right... When precisely engaged with mounting block 306, it can securely fix laser cutting head 305, ensuring the accuracy of the cutting process. When replacing parts, simply activate hydraulic rod 301, which will pull slider 304 to the left, thus easily removing laser cutting head 305. The entire operation is simple and quick, greatly improving work efficiency. This design not only achieves efficient cutting of multi-specification sealing rings, but also ensures smooth and burr-free cutting edges, significantly improving the first-pass yield. Furthermore, it can adapt to materials of different hardness, such as silicone and fluororubber, demonstrating excellent adaptability and practicality. The motor 401 drives the turntable 4051 through rotation. When the turntable 4051 starts to rotate, it can drive the slide rod 406 to slide smoothly on the inner wall of the slide groove 4052. The sliding of the slide rod 406 further drives the crank 404, so that the crank 404 can rotate flexibly on the shaft 403. This ingenious design allows multiple slide rods 406 to slide synchronously in the slide groove 4052 and can move to the center or the periphery as needed, greatly improving the flexibility and versatility of operation. When the sealing ring is put on the outer wall of the slide rod 406, the slide rod 406 can spread it evenly to accommodate sealing rings of different diameters, which provides great convenience for the cutting work and ensures the efficiency and accuracy of the cutting process.
