Through a specially designed cutting tool and positioning mechanism, it allows adjustment of cutting parameters according to the tube specifications, ensuring a clean, burr-free cut. The device features an automated feed system that controls cutting speed and depth, reducing material waste. Some models are also equipped with dust removal and cooling devices, improving working environment safety and tool life. It is widely used in machinery manufacturing and other fields to meet diverse tube cutting needs.

[0003] According to a published disclosure (Publication No.: CN119407865A), a torque-driven rubber core tube positioning and cutting device includes: a frame and a cutting mechanism. A turntable is rotatably connected to the frame below the cutting mechanism. The frame is equipped with a shifting mechanism. The turntable has four working surfaces on its side.

[0004] However, the above-mentioned applications have problems such as poor cutting effect and poor material transmission effect. Therefore, a torsion rubber core tube cutting device is proposed. Utility Model Content

[0005] This invention proposes a torsion rubber core tube cutting device, which solves the problems of poor cutting effect and poor material transmission effect in related technologies.

[0006] According to one aspect, at least one embodiment of this disclosure provides a torque-driven rubber core tube cutting device, comprising: a machine body, a support foot pad fixedly connected to the bottom of the machine body, a door panel slidably connected to the inner side of the machine body, a handle fixedly connected to the side of the door panel, a worktable fixedly connected to the inner side of the machine body, a gantry frame fixedly connected to the top of the worktable, a feeding rack fixedly connected to the side of the machine body, and an automatic feeding mechanism provided inside the machine body; The automatic feeding mechanism includes a motor, the bottom of which is fixedly connected to the inner side of the machine body. A threaded rod is fixedly connected to the end of the motor output shaft. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A connecting rod is fixedly connected to the circumferential surface of the threaded sleeve. A displacement plate is fixedly connected to the end of the connecting rod away from the threaded sleeve. A rotating shaft is fixedly connected to the end of the threaded rod away from the motor. The end of the rotating shaft away from the threaded rod is rotatably connected to the inner side of the machine body.

[0007] For example, in at least one embodiment of the present disclosure of a torque-driven rubber core tube cutting device, the device further includes: a slide rail is provided on the side of the machine body, and there are two slide rails, which are symmetrical to each other along the vertical central axis of the door panel. This ensures that the door panel slides smoothly along a fixed trajectory during opening and closing, avoiding shaking or deviation, thereby ensuring the safety and reliability of the equipment operation.

[0008] The side of the door panel is fixedly connected with two slide bars, which are symmetrical about each other along the vertical central axis of the door panel to ensure that the door panel moves in a straight line during sliding, avoiding jamming or wear due to deviation, and improving the stability of the device operation.

[0009] The number of support feet is set to several and they are symmetrical to each other along the vertical central axis of the machine body. The width of the slide bar is equal to the width of the slide rail, which can evenly bear the weight of the machine body and internal mechanism and avoid the device tilting due to the shift of the center of gravity.

[0010] The top of the displacement plate and the bottom of the feeding rack are provided with arc grooves. The arc grooves on the top of the displacement plate and the arc grooves on the bottom of the feeding rack are concentric. The shaft tube is a cylindrical structure. The curved surface of the arc groove matches the shape of the outer surface of the shaft tube. It can form a stable support through multi-point contact, avoiding the shaft tube from shaking, shifting or rolling during the feeding process due to the support surface not fitting properly, and ensuring that the shaft tube axis is consistent with the movement direction of the cutting device.

[0011] According to another aspect, at least one embodiment of this disclosure also provides a torque-driven rubber core tube cutting device, comprising: a hydraulic cutting mechanism, the hydraulic cutting mechanism including a half gear, the inner side of the half gear being fixedly connected to the circumferential surface of a rotating shaft, a slider being slidably connected to the inner side of the machine body, a rack being fixedly connected to the side of the slider, the half gear and the rack meshing with each other, a spring being fixedly connected to the bottom of the rack, the end of the spring away from the rack being fixedly connected to the inner side of the machine body, a hydraulic tank being fixedly connected to the top of the gantry frame, and the gantry... A return spring is fixedly connected to the top of the gantry. A hydraulic plate is fixedly connected to the end of the return spring away from the gantry. A cutter bar is fixedly connected to the bottom of the hydraulic plate. A cutting blade is fixedly connected to the end of the cutter bar away from the hydraulic plate. The side of the cutting blade is slidably connected to the side of the gantry. A water tank is fixedly connected to the side of the gantry. A U-shaped plate is fixedly connected to the side of the rack. A water supply plate is fixedly connected to the end of the U-shaped plate away from the rack. A water pipe is fixedly connected to the top of the water tank. The end of the water pipe away from the water tank is fixedly connected to the top of the hydraulic tank.

[0012] For example, in at least one embodiment of the present disclosure, a torque rubber core tube cutting device is provided, which further includes: two springs are provided and are symmetrical to each other along the vertical central axis of the rack, which can ensure that the rack is subjected to uniform force during up and down movement, avoid the rack tilting or jamming due to force on one side, and thus ensure the stability of the meshing between the half gear and the rack; and several return springs are provided and are arranged in a circumferential array on the top of the gantry.

[0013] The gantry frame has two sliding grooves on its side, which are symmetrical about each other along the vertical central axis of the gantry frame. The cutting blade is fixedly connected to two sliding bars on its side, which are also symmetrical about each other along the vertical central axis of the cutting blade. This ensures that the blade bar is always perpendicular to the axis of the shaft tube during the cutting process, and avoids tilting of the cutting surface or the generation of burrs due to lateral offset.

[0014] The water tank has slide rails on its side. Several slide rails are arranged in a linear array on the side of the water tank. The linear array of slide rails ensures that the U-shaped plate maintains a straight movement when it is raised and lowered, preventing sealing failure or liquid leakage due to guide deviation.

[0015] The side of the gantry is located on the displacement trajectory of the displacement plate, and the top of the worktable is located on the displacement trajectory of the cutting blade. This ensures that the displacement plate moves along a preset straight line, avoiding deviation due to inertia or external force, and ensures that the blade tip is strictly perpendicular to the surface of the shaft tube when the cutting blade descends, avoiding dimensional deviations caused by oblique cutting.

[0016] The working principle and beneficial effects of this utility model are as follows: 1. This utility model achieves unmanned continuous operation and significantly improves production efficiency through the coordinated operation of components such as threaded rods, connecting rods, and displacement plates within the automatic feeding mechanism. The concentric design of the displacement plate and the arc groove of the feeding rack ensures precise positioning of the shaft tube, preventing offset and ensuring consistent cutting dimensions. Its rotating shaft is linked with the hydraulic cutting mechanism, allowing the feeding and cutting actions to be naturally synchronized, simplifying the control logic. This mechanism has a compact structure, high reliability, and is compatible with shaft tubes of different specifications, making it highly practical.

[0017] 2. In this utility model, the interplay of components such as the half-gear, rack, and U-shaped plate within the hydraulic cutting mechanism achieves synchronized cutting and feeding, reducing energy consumption. The hydraulic tank and return spring work together to ensure smooth downward and return of the cutting blade, guaranteeing cutting accuracy. The water supply plate provides water cooling synchronously with the rack's movement, extending tool life. The guide structure of the slide groove and slide bar ensures cutting perpendicularity. The combination of mechanical and hydraulic design simplifies the system structure, improves cutting efficiency and equipment reliability, and adapts to the needs of automated shaft and tube processing.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-5 As shown, a torque rubber core tube cutting device according to an embodiment of the present disclosure is illustrated, comprising: a body 1, a support foot pad 2 fixedly connected to the bottom of the body 1, a door panel 3 slidably connected to the inner side of the body 1, a handle 4 fixedly connected to the side of the door panel 3, a workbench 5 fixedly connected to the inner side of the body 1, a gantry frame 6 fixedly connected to the top of the workbench 5, a feeding rack 7 fixedly connected to the side of the body 1, and an automatic feeding mechanism 8 provided inside the body 1. The automatic feeding mechanism 8 includes a motor 81, the bottom of which is fixedly connected to the inner side of the machine body 1. A threaded rod 82 is fixedly connected to the end of the output shaft of the motor 81. A threaded sleeve 83 is threadedly connected to the circumferential surface of the threaded rod 82. A connecting rod 84 is fixedly connected to the circumferential surface of the threaded sleeve 83. A displacement plate 85 is fixedly connected to the end of the connecting rod 84 away from the threaded sleeve 83. A rotating shaft 86 is fixedly connected to the end of the threaded rod 82 away from the motor 81. The end of the rotating shaft 86 away from the threaded rod 82 is rotatably connected to the inner side of the machine body 1.

[0026] In some examples, the machine body 1 is provided with two slide rails on its side, which are symmetrical about each other along the vertical central axis of the door panel 3. This ensures that the door panel 3 slides smoothly along a fixed trajectory during opening and closing, avoiding shaking or deviation, thereby ensuring the safety and reliability of the equipment operation.

[0027] The side of the door panel 3 is fixedly connected with two slide bars, which are symmetrical about each other along the vertical central axis of the door panel 3. This ensures that the door panel 3 moves in a straight line during sliding, avoids jamming or wear due to deviation, and improves the stability of the device operation.

[0028] The number of support feet 2 is set to be several, and they are symmetrical to each other along the vertical central axis of the body 1. The width of the slide bar is equal to the width of the slide rail, which can evenly bear the weight of the body 1 and the internal mechanism, and avoid the device from tilting due to the shift of the center of gravity.

[0029] The top of the displacement plate 85 and the bottom of the feed rack 7 are provided with arc grooves. The arc grooves on the top of the displacement plate 85 and the arc grooves on the bottom of the feed rack 7 are concentric. The shaft tube is a cylindrical structure. The curved surface of the arc groove matches the shape of the outer surface of the shaft tube. It can form a stable support through multi-point contact, avoiding the shaft tube from shaking, shifting or rolling during the feeding process due to the non-fitting support surface, and ensuring that the shaft tube axis is consistent with the movement direction of the cutting device.

[0030] For example, such as Figures 1-5 As shown, the staff remotely controls the switch of motor 81. Motor 81 is the power source. After motor 81 starts, the output shaft drives the threaded rod 82 to rotate. The threaded sleeve 83, which is threaded to the threaded rod 82, generates linear displacement due to rotation. Through the connecting rod 84, it pushes the displacement plate 85 to move along the set trajectory. The concentric arc groove of the top of the displacement plate 85 and the bottom of the feed rack 7 precisely clamps the shaft tube, ensuring the stability of the shaft tube axis during the feeding process.

[0031] like Figures 1-5The diagram illustrates a torque-driven rubber core tube cutting device according to another embodiment of this disclosure, comprising: a hydraulic cutting mechanism 9, which includes a half gear 91, the inner side of which is fixedly connected to the circumferential surface of a rotating shaft 86; a slider 92 slidably connected to the inner side of a body 1; a rack 93 fixedly connected to the side of the slider 92; the half gear 91 and the rack 93 meshing with each other; a spring 94 fixedly connected to the bottom of the rack 93; the end of the spring 94 away from the rack 93 fixedly connected to the inner side of the body 1; a hydraulic tank 95 fixedly connected to the top of a gantry frame 6; and a reset mechanism fixedly connected to the top of the gantry frame 6. Spring 96, the end of the return spring 96 away from the gantry frame 6 is fixedly connected to a hydraulic plate 97, the bottom of the hydraulic plate 97 is fixedly connected to a knife bar 98, the end of the knife bar 98 away from the hydraulic plate 97 is fixedly connected to a cutting blade 99, the side of the cutting blade 99 is slidably connected to the side of the gantry frame 6, the side of the gantry frame 6 is fixedly connected to a water tank 910, the side of the rack 93 is fixedly connected to a U-shaped plate 911, the end of the U-shaped plate 911 away from the rack 93 is fixedly connected to a water supply plate 912, the top of the water tank 910 is fixedly connected to a water pipe 913, the end of the water pipe 913 away from the water tank 910 is fixedly connected to the top of the hydraulic tank 95.

[0032] In some examples, the following are also included: two springs 94 are provided and are symmetrical to each other along the vertical central axis of the rack 93, which can ensure that the rack 93 is subjected to uniform force during up and down movement, and avoid the rack 93 tilting or jamming due to force on one side, thereby ensuring the stability of the meshing between the half gear 91 and the rack 93. Several return springs 96 are provided and are arranged in a circumferential array on the top of the gantry 6.

[0033] The side of the gantry frame 6 is provided with two sliding grooves, which are symmetrical about each other along the vertical central axis of the gantry frame 6. The side of the cutting blade 99 is fixedly connected with two sliding strips, which are symmetrical about each other along the vertical central axis of the cutting blade 99. This ensures that the blade shank 98 is always perpendicular to the axis of the shaft tube during the cutting process, and avoids the cutting surface from tilting or producing burrs due to lateral offset.

[0034] The side of the water tank 910 is provided with slide rails. There are several slide rails arranged in a linear array on the side of the water tank 910. The linear array of slide rails can ensure that the U-shaped plate 911 maintains a straight movement when it is raised and lowered, and prevents sealing failure or liquid leakage due to guide deviation.

[0035] The side of the gantry 6 is located on the displacement trajectory of the displacement plate 85, and the top of the worktable 5 is located on the displacement trajectory of the cutting blade 99. This ensures that the displacement plate 85 moves along a preset straight line, avoiding deviation due to inertia or external force, and ensures that the blade tip is strictly perpendicular to the surface of the shaft tube when the cutting blade 99 descends, avoiding dimensional deviations caused by oblique cutting.

[0036] For example, such as Figures 1-5 As shown, when the automatic feeding mechanism 8 is running, the rotating shaft 86 drives the half gear 91 to rotate, meshing with the rack 93 to move it upwards. The spring 94 is compressed and stores energy. At the same time, the rack 93 drives the U-shaped plate 911 and the water supply plate 912 to move, and the water pipe 913 transports water from the water tank 910 to the hydraulic tank 95. The hydraulic tank 95, under pressure, drives the hydraulic plate 97, the cutter bar 98, and the cutting blade 99 to descend, cutting the shaft tube. After cutting, the half gear 91 disengages, the spring 94 resets, driving the rack 93 to move downwards, the hydraulic tank 95 is depressurized, and the reset spring 96 causes the hydraulic plate 97 to rise, resetting the cutting blade 99, completing one cutting cycle.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
