Description

Technical Field

[0001] This application relates to the field of cutting equipment technology, and more specifically, to a rubber seal ring cutting device. Background Technology

[0002] Rubber seals are used to connect parts such as bearings, effectively preventing lubricant leakage and the intrusion of foreign objects. The manufacturing process of rubber seals involves multiple steps, including cutting and vulcanization. First, the rubber raw material is processed into long rubber hoses. These hoses are then manually cut into preliminary rubber seals of appropriate length using a handheld cutting tool. Next, these preliminary rubber seals undergo vulcanization to solidify. The vulcanized rubber seals can be further processed as needed, such as through heat fusion welding, to enhance their strength and sealing performance, forming the final rubber seal. However, manual cutting has several drawbacks: it is tedious and time-consuming, failing to meet the demands for efficient and rapid operation, thus affecting work efficiency. Furthermore, manual cutting is difficult to achieve in terms of precision and consistency, potentially resulting in inconsistent cut lengths of the preliminary rubber seals, which in turn affects the normal use of the product. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a rubber sealing ring cutting device, including a worktable and a cutting box vertically mounted on the top of the worktable. A heating wire assembly is mounted on the cutting box and is laterally positioned inside the cutting box, moving within it. A box cover is driven onto the worktable and vertically covers the top of the cutting box. The box cover moves up and down from the top of the cutting box. By simultaneously moving the heating wire assembly and the box cover towards and squeezing a long rubber hose placed laterally on the top of the cutting box, the contact area between the long rubber hose and the heating wire assembly is softened by high temperature. Under the pressure of the box cover, the long rubber hose is thermally cut, thereby obtaining a preliminary rubber sealing ring.

[0004] Preferably, the heating wire assembly includes a heater, which is electrically connected to an external power source. The heater has multiple cutting lines that contact a long rubber hose. The cutting lines are neatly distributed on the heater, and each cutting line is electrically connected to the heater. Adjacent cutting lines do not contact each other.

[0005] Preferably, the top of the workbench is vertically formed with a support column, which is located on one side of the cutting box. A first cylinder is provided on the top of the support column, which vertically penetrates the support column. One end of the first cylinder is connected to the box cover for driving. Multiple pressure plates are formed on the box cover. The pressure plates are neatly arranged at the bottom of the box cover along the length of the box cover, and there is a gap between adjacent pressure plates. The first cylinder drives the box cover and the pressure plates to rise and fall on the top of the cutting box.

[0006] Preferably, multiple lifting cylinders are vertically arranged between the cutting box and the heating wire assembly, and the lifting cylinders are all neatly distributed inside the cutting box, with the top of the lifting cylinders being drivenly connected to the heating wire assembly.

[0007] Preferably, the heating wire assembly has sliders formed on it, and the sliders are located on both sides of the heating wire assembly, and the sliders move synchronously with the heating wire assembly. The cutting box has grooves formed on it, and the grooves are located on both sides inside the cutting box, and the grooves and sliders slide together.

[0008] Preferably, a movable stage is provided on the top of the workbench, and the movable stage is vertically located on one side of the cutting box and movable on one side of the cutting box. A second cylinder is provided on the side of the workbench, and the second cylinder passes through the workbench laterally. One end of the second cylinder is driven to the movable stage, and the movable stage is driven to move by the second cylinder, thereby causing the movable stage to move laterally back and forth on one side of the cutting box.

[0009] Preferably, the movable platform is provided with a gripper, which is laterally located on one side of the movable platform and moves synchronously with the movable platform. A third cylinder is provided on the other side of the movable platform, which laterally passes through the movable platform and one end of the third cylinder is drivenly connected to the gripper.

[0010] Preferably, a slide rail assembly is provided between the worktable and the movable table, and the slide rail assembly is located laterally on the top of the worktable. The slide rail assembly moves in coordination with the worktable. The bottom of the movable table is connected to the slide rail assembly, and the movable table and the slide rail assembly move in the same direction. By providing the slide rail assembly, the second cylinder drives the movable table to move laterally back and forth on one side of the cutting box more smoothly.

[0011] Preferably, a first arc-shaped groove is formed on one side of the cutting box, and the first arc-shaped groove extends horizontally through the cutting box. A long rubber hose is placed horizontally in the first arc-shaped groove. A second arc-shaped groove is formed on the box cover to engage with the first arc-shaped groove. The second arc-shaped groove is located on both sides of the box cover, and the second arc-shaped groove contacts the top of the long rubber hose placed horizontally in the first arc-shaped groove.

[0012] Preferably, the top of the workbench is provided with a support platform, which is vertically located on the other side of the cutting box. The top of the support platform is formed with an inwardly shaped support groove for supporting long rubber hoses. The top of the workbench is formed with a material discharge channel, which vertically penetrates the workbench. One end of the material discharge channel is connected to the inside of the cutting box. The bottom of the workbench is placed on the material discharge box, and the opening of the material discharge box is connected to the other end of the material discharge channel. The material discharge box is connected to the inside of the cutting box through the material discharge channel.

[0013] In summary, the beneficial effects of this application are as follows:

[0014] When the long rubber hose is placed horizontally on top of the cutting box, the heating wire assembly begins to heat up and moves towards the hose simultaneously with the lid. This continues until the heating wire assembly and lid are in contact with the hose. The area where the hose contacts the heating wire gradually softens under the heat. At this point, the lid continues to move towards the hose and apply pressure, cutting the hose at the point of contact and producing a preliminary rubber sealing ring. After the hose is completely cut, the heating wire assembly and lid return to their initial positions. This thermal cutting method, using the heating wire assembly and lid in conjunction, replaces manual hand-held cutting tools, improving cutting efficiency and overall precision. It effectively solves the drawbacks of manual cutting: manual operation is cumbersome and time-consuming, failing to meet the demands of high-efficiency and rapid operation, thus affecting work efficiency. Furthermore, manual cutting is difficult to achieve in terms of precision and consistency, potentially resulting in inconsistent cut lengths of the preliminary rubber sealing rings, which can affect the normal use of the product.

[0026] A rubber seal cutting device, see Figures 1 to 6The system includes a workbench 1 and a cutting box 2 vertically mounted on top of the workbench 1. A heating wire assembly 3 is mounted on the cutting box 2 and is laterally positioned inside the cutting box 2, moving within it. A lid 4 is driven onto the workbench 1 and vertically covers the top of the cutting box 2. The lid 4 rises and falls from the top of the cutting box 2. By simultaneously moving the heating wire assembly 3 and the lid 4 towards and squeezing a long rubber hose 5 positioned laterally on top of the cutting box 2, the contact point between the long rubber hose 5 and the heating wire assembly 3 is softened by high temperature. Under pressure from the lid 4, the long rubber hose 5 is thermally cut to obtain a preliminary rubber sealing ring 23. In this embodiment, the initial positions of the lid 4 and the heating wire assembly 3 are as follows: the lid 4 is located at the top of the cutting box 2, and the lid 4 and the cutting box 2 do not contact each other, and the heating wire assembly 3 is located at the bottom of the cutting box 2; when the long rubber hose 5 is placed horizontally on the top of the cutting box 2, the heating wire assembly 3 starts to heat up and moves towards the long rubber hose 5 placed horizontally on the top of the cutting box 2 simultaneously with the lid 4, until the heating wire assembly 3 and the lid 4 respectively contact the long rubber hose 5. The contact area between the long rubber hose 5 and the heating wire gradually softens under the heat of the heating wire. At this time, the lid 4 continues to move towards the long rubber hose 5 and apply pressure to it, so that the contact area between the long rubber hose 5 and the heating wire can be cut to obtain the initial rubber sealing ring 23. After the long rubber hose 5, which is placed horizontally on the top of the cutting box 2, is cut, the heating wire assembly 3 and the lid 4 simultaneously return to their initial positions. When it is necessary to cut the remaining part of the long rubber hose 5, simply place the remaining part of the long rubber hose 5 horizontally on the top of the cutting box 2, and then repeat the above steps. The above steps can complete a new round of cutting work. In this embodiment, the heating wire assembly 3 and the box cover 4 cooperate to perform thermal cutting instead of manual hand-held cutting tools to cut the long rubber hose 5. This not only improves the cutting efficiency, but also has a higher overall cutting accuracy. It effectively solves the drawbacks of manual cutting: manual operation is not only cumbersome and time-consuming, but also cannot meet the needs of efficient and fast operation, affecting work efficiency. Moreover, manual cutting is difficult to achieve accuracy and consistency, which may result in inconsistent cutting lengths of the initial rubber sealing ring 23, thus affecting the normal use of the product.

[0027] The heating wire assembly 3 includes a heater 301, which is electrically connected to an external power source. The heater 301 has multiple cutting lines 302 that contact the long rubber hose 5. These cutting lines 302 are neatly distributed on the heater 301 and are electrically connected to it. Adjacent cutting lines 302 do not contact each other. In this embodiment, the heater 301 is powered by an external power source, generating heat. The heater 301 then transfers this heat to the cutting lines 302, causing them to heat up. This heat softens the contact area between the long rubber hose 5 and the cutting lines 302. Under the pressure of the lid 4, the long rubber hose 5, placed horizontally at the top of the cutting box 2, is finally thermally cut. The gap between adjacent cutting lines 302 is related to the cutting length of the long rubber hose 5, so the gap needs to be set according to the actual site conditions. This embodiment does not impose specific limitations on this gap.

[0028] A support column 6 is vertically formed on the top of the workbench 1, and the support column 6 is located on one side of the cutting box 2. A first cylinder 7 is provided on the top of the support column 6, and the first cylinder 7 vertically penetrates the support column 6. One end of the first cylinder 7 is driven and connected to the box cover 4. A plurality of pressure plates 8 are formed on the box cover 4. The pressure plates 8 are neatly arranged at the bottom of the box cover 4 along the length direction of the box cover 4, and there is a gap between adjacent pressure plates 8. The first cylinder 7 drives the box cover 4 and the pressure plates 8 to rise and fall on the top of the cutting box 2. In this embodiment, when the first cylinder 7 drives the box cover 4 and the pressure plates 8 to descend on the top of the cutting box 2, the adjacent pressure plates 8 press against the cut surface. The cutting lines 302 are brought into contact with and pressurized at the two sides of the softened area, thereby thermally cutting the long rubber hose 5 placed horizontally on the top of the cutting box 2 to obtain a preliminary rubber sealing ring 23 of a certain length. At this time, the cutting lines 302 are all located in the gap between adjacent pressure plates 8 to avoid gaps, while the pressure plates 8 pass through the gap between adjacent cutting lines 302. Through the above design, not only can the interference between the cutting lines 302 and the pressure plates 8 be prevented, but the preliminary rubber sealing ring 23 adhering to the cutting lines 302 can also be cleaned by the pressure plates 8, which effectively improves the practicality of this embodiment.

[0029] Multiple lifting cylinders 9 are vertically arranged between the cutting box 2 and the heating wire assembly 3, and the lifting cylinders 9 are all neatly distributed inside the cutting box 2. The top of the lifting cylinder 9 is driven to the heating wire assembly 3. In this embodiment, the heating wire assembly 3 is moved by the lifting cylinder 9, thereby causing the heating wire assembly 3 to rise and fall inside the cutting box 2.

[0030] The heating wire assembly 3 has a slider 10 formed on it, and the slider 10 is located on both sides of the heating wire assembly 3. The slider 10 moves synchronously with the heating wire assembly 3. The cutting box 2 has a sliding groove 11 formed on it, and the sliding groove 11 is located on both sides inside the cutting box 2. The sliding groove 11 and the slider 10 slide in cooperation. In this embodiment, the cooperation between the sliding groove 11 and the slider 10 makes the lifting cylinder 9 drive the heating wire assembly 3 to move up and down inside the cutting box 2 more smoothly, and there will be no positional deviation, which would affect the normal operation.

[0031] A movable stage 12 is provided on the top of the workbench 1, and the movable stage 12 is vertically located on one side of the cutting box 2. The movable stage 12 moves on one side of the cutting box 2. A second cylinder 13 is provided on the side of the workbench 1, and the second cylinder 13 passes through the workbench 1 laterally. One end of the second cylinder 13 is driven to the movable stage 12. The movable stage 12 is driven to move by the second cylinder 13, thereby causing the movable stage 12 to move laterally back and forth on one side of the cutting box 2.

[0032] The moving platform 12 is provided with a gripper 14, which is laterally located on one side of the moving platform 12 and moves synchronously with the moving platform 12. A third cylinder 15 is provided on the other side of the moving platform 12 and extends laterally through the moving platform 12. One end of the third cylinder 15 is driven to the gripper 14. In this embodiment, the gripper 14 is driven by the third cylinder 15 to open and close on the side of the moving platform 12, so that the gripper 14 can clamp and limit the thickness of the remaining part of the long rubber hose 5. With the cooperation of the second cylinder 13 and the moving platform 12, the remaining part of the long rubber hose 5 that needs to be cut is placed laterally on the top of the cutting box 2.

[0033] A slide rail assembly 16 is provided between the worktable 1 and the movable stage 12. The slide rail assembly 16 is located laterally on the top of the worktable 1, and the slide rail assembly moves in coordination with the worktable 1. The bottom of the movable stage 12 is connected to the slide rail assembly, and the movable stage 12 and the slide rail assembly move in the same direction. By providing the slide rail assembly 16, the second cylinder 13 drives the movable stage 12 to move laterally back and forth on one side of the cutting box 2 more smoothly.

[0034] The cutting box 2 has a first arc-shaped groove 17 formed on one side, and the first arc-shaped groove 17 extends horizontally through the cutting box 2. The long rubber hose 5 is placed horizontally in the first arc-shaped groove 17. The box cover 4 has a second arc-shaped groove 18 formed on it, which engages with the first arc-shaped groove 17. The second arc-shaped groove 18 is located on both sides of the box cover 4, and the second arc-shaped groove 18 contacts the top of the long rubber hose 5 placed horizontally in the first arc-shaped groove 17. In this embodiment, the first arc-shaped groove 17 and the second arc-shaped groove 18 cooperate with each other to simultaneously limit the bottom and top positions of the long rubber hose 5 placed horizontally at the top of the cutting box 2, which can effectively prevent the long rubber hose 5 from shifting position during the cutting process, thereby affecting the normal cutting operation.

[0035] The workbench 1 is topped with a support platform 19, which is vertically positioned on the other side of the cutting box 2. The top of the support platform 19 has an inwardly formed support groove 20 for supporting a long rubber hose 5. A material discharge channel 21 is formed on the top of the workbench 1, vertically penetrating the workbench 1, with one end connected to the interior of the cutting box 2. The bottom of the workbench 1 is placed on a material discharge box 22, the opening of which is connected to the other end of the material discharge channel 21. The material discharge box 22 is connected to the interior of the cutting box 2 via the material discharge channel 21. In this embodiment, by providing the support platform 19 and the support... The groove 20 can support and limit the remaining part of the long rubber hose 5 after it is cut, which is placed horizontally at the top of the cutting box 2. This prevents the remaining part of the long rubber hose 5 from hanging on the workbench 1 due to lack of support, which would affect the subsequent cutting of the remaining part of the long rubber hose 5. The pre-finished rubber sealing ring 23 after thermal cutting can fall into the dropping box 22 through the dropping channel 21 for collection. This makes it convenient for workers to collect the pre-finished rubber sealing ring 23 and transport it to the next processing step, reducing the labor intensity of workers and effectively improving the practicality of this embodiment.

[0036] The above embodiments are merely explanations of this application and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
