Description
Technical Field
[0001] This invention relates to the field of hose cutting machine technology, and particularly to a hose ring cutting machine. Background Technology
[0002] A hose cutting machine is an automated or semi-automated piece of equipment specifically designed for cutting various types of hoses, such as rubber hoses, plastic hoses, and silicone hoses. It is widely used in industrial manufacturing, automotive repair, hydraulic system assembly, and other applications.
[0003] Most hose cutting machines on the market are primarily designed for cutting hoses with an outer diameter of less than 100mm. When cutting hoses with an outer diameter greater than 100mm and multiple layers of reinforcing steel wire, conventional cutting machine blades or laser heads either cannot penetrate the steel wire layer due to the multiple layers of high-hardness steel wire braids, resulting in delamination of the hose and outward-facing steel wire breaks. Therefore, the industry still widely uses the traditional method of manually operating abrasive wheel saws for cutting. This method is not only time-consuming, labor-intensive, and inefficient, but also prone to problems such as skewed cuts, rubber burrs adhering to the cut surface, and uneven steel wire breaks. Additional manpower is required for secondary cutting correction and fine grinding, which not only prolongs the processing cycle but also significantly increases labor costs and material waste. More importantly, even after manual processing, the flatness of the cut cannot meet the precision standards of automated assembly, requiring the use of large-diameter wiring rotary joints. Summary of the Invention

The cutting assembly is movably disposed inside the main support frame. The cutting assembly includes two sets of cutting motors for cutting large-diameter multi-layer steel wire reinforced rubber tubes, and the cutting motors can rotate around the rubber tube.
[0006] Preferably, the cutting assembly further includes a sliding ring and a side opening; The slip ring is used to connect the cutting motor. The cutting motor is symmetrically distributed on the slip ring, and the slip ring can rotate with a rotation angle greater than 180 degrees and less than 190 degrees.
[0007] The side opening is formed on the slip ring, allowing a large-diameter multi-layer steel wire reinforced rubber tube to enter the interior of the slip ring from the side.
[0008] Preferably, the cutting assembly further includes an outer peripheral toothed groove, a toothed disc, and a fine-tuning telescopic seat; The outer peripheral groove is formed on the outer edge of the sliding ring and is used to mesh with the gear plate; The gear disk is used to drive the sliding ring to perform circular motion; The fine-tuning telescopic seat is used to connect the slip ring and the cutting motor.
[0009] Preferably, the main support has a limiting groove inside for guiding and limiting the rotation of the sliding ring.
[0010] Preferably, the clamping assembly includes a clamping cylinder, a positioning clamping block, and a guide post; The clamping cylinders are symmetrically distributed at the ends of the main support and are used to drive the positioning clamps to perform telescopic movements. The positioning clamp is located at the output end of the clamping cylinder and is used to clamp and position the large-diameter multi-layer steel wire reinforced rubber tube to be cut. The guide post is disposed on one side of the positioning clamp block and is used to guide and limit the movement of the positioning clamp block.
[0011] Preferably, it also includes a lifting assembly for controlling the height of the main support; The lifting assembly includes a first base and a lifting mechanism; The first base is located below the main support frame and is used to support the elevator; The lifting mechanism is located on the upper surface of the first base and is used to lift the main support frame.
[0012] Preferably, it also includes a lateral movement component for controlling the horizontal lateral position of the main support, the lateral movement component being disposed on the first base for driving the first base to move laterally.
[0013] Preferably, the lateral movement assembly includes: a drive gear, a lateral movement rack, and a lateral movement power source; The drive gear is rotatably mounted on the lower end face of the first base and meshes with the transverse rack. The transverse rack is distributed along the moving direction of the first base and is used to guide the first base. The lateral force source is located on the upper surface of the first base and is used to drive the drive gear to rotate.
[0014] Preferably, it also includes a longitudinal movement component for controlling the horizontal longitudinal position of the main support; The longitudinal movement component includes: a longitudinal movement guide rail, a second base, a moving roller, and a longitudinal movement power source; The longitudinal guide rail is used to guide the movement direction of the main support; The second base is slidably mounted on the longitudinal guide rail, and the second base is connected to the transverse rack; The movable roller is disposed on the second base and can roll along the extension direction of the longitudinal guide rail.

Detailed Implementation
[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0021] like Figure 1 - Figure 8 As shown in the figure, this embodiment proposes a hose ring cutting machine, including a main support 1, a clamping assembly 2 and a cutting assembly 3.
[0022] Specifically, the clamping component 2 is located at the front and rear ends of the main support 1 and is used to clamp and position the large-diameter multi-layer steel wire reinforced rubber hose.
[0023] Specifically, the cutting assembly 3 is movably installed inside the main support 1. The cutting assembly 3 includes two sets of cutting motors 36 for cutting large-diameter multi-layer steel wire reinforced rubber tubes, and the cutting motors 36 can rotate around the rubber tube.
[0024] In this embodiment, the cutting assembly 3 also includes a sliding ring 31 and a side opening 32.
[0025] Furthermore, the slip ring 31 is used to connect the cutting motor 36, which is symmetrically distributed on the slip ring 31, and the slip ring 31 can rotate with a rotation angle greater than 180 degrees and less than 190 degrees.
[0026] Specifically, the slip ring 31 is a ring-shaped metal frame with an outer diameter that matches the limiting groove 11 of the main support 1, and an inner diameter designed according to the maximum outer diameter of the cutting hose. The slip ring 31 serves as the mounting carrier for the cutting motor 36, and through its cooperation with the limiting groove 11, it drives the cutting motor 36 to move around the hose, achieving ring-shaped cutting. Simultaneously, the ring-shaped structure of the slip ring 31 ensures that the cutting trajectory is always perfectly circular, preventing elliptical or skewed cuts. In this embodiment, the cutting motor 36 mounted on the slip ring 31 is preferably a high-speed motor. A diamond cutting saw blade is installed at the output end of the cutting motor 36 to ensure smooth cutting of the multi-layered steel wire reinforced hose. Two sets of cutting motors 36 are distributed opposite each other on the slip ring 31. Through the high-speed rotating diamond saw blade, the steel wire reinforced layer and rubber layer of the hose are cut simultaneously. Compared to single-motor cutting, the cutting time can be halved, improving efficiency. Furthermore, the symmetrically distributed cutting motors 36 can balance the cutting force, preventing the hose from deforming due to unilateral force and ensuring a smooth cut. The maximum rotation angle of the slip ring 31 is set to be greater than 180° and less than 190°, ensuring that the two sets of cutting motors 36 can completely cover the circumference of the hose. Theoretically, since the two sets of cutting motors 36 are symmetrically distributed, a full circle cut can be completed when the two sets of cutting motors 36 rotate 180°. However, during the cutting process, the outer diameter of the hose is not the theoretical circumference, and there is also a bend in the tubing. To ensure the thoroughness of the cut, an additional angle of 0°-10° is reserved to avoid incomplete cutting, ensuring that the steel wire layer is completely cut off, eliminating the need for subsequent secondary cutting, and preventing excessive overlapping cutting areas.
[0027] Furthermore, a side opening 32 is provided on the sliding ring 31, allowing large-diameter multi-layer steel wire reinforced rubber hoses to enter the interior of the sliding ring 31 from the side. The width of the side opening 32 is slightly larger than the outer diameter of the largest cutting hose, thus ensuring that the large-diameter hose can be placed inside the sliding ring 31 from the side. As a result, the large-diameter hose can be inserted not only from the end of the sliding ring 31 but also from the side of the sliding ring 31, greatly simplifying the feeding process. It is especially suitable for large-diameter hoses that are long, heavy, and difficult to move, reducing the intensity of manual feeding. At the same time, the design of the side opening 32 of the sliding ring 31 also allows the device to directly cut the large-diameter hose during continuous production, making it suitable for continuous production processes of hoses.
[0028] In this embodiment, the cutting assembly 3 also includes an outer peripheral toothed groove 33, a toothed disc 34, and a fine-tuning telescopic seat 35.
[0029] Furthermore, the outer peripheral groove 33 is formed on the outer edge of the sliding ring 31 for meshing with the gear disk 34. The gear disk 34 is used to drive the sliding ring 31 to perform circumferential motion. In this embodiment, the outer peripheral groove 33 with a continuous tooth structure is formed at the outer peripheral edge of the sliding ring 31. The outer peripheral groove 33 meshes with the teeth of the gear disk 34 to transmit the rotational power of the gear disk 34 to the sliding ring 31. Through the high-precision characteristics of gear transmission, the rotational speed of the sliding ring 31 is ensured to be uniform, avoiding fluctuations in cutting depth due to unstable power transmission and ensuring the quality of the cut.
[0030] Specifically, the gear disk 34 is driven by a power source set in the main support 1. The power source is preferably a servo motor (not labeled in the figure). The servo motor is electrically connected to the control box 9. The gear disk 34 and the outer peripheral tooth groove 33 of the slip ring 31 mesh as a power transmission medium, converting the high torque power of the servo motor into the circular motion of the slip ring 31. The servo motor can adjust its speed through the control box 9 to adapt to the cutting requirements of rubber tubes with different thicknesses of steel wire reinforcement layers. If there are many layers of steel wire, the speed is reduced to ensure thorough cutting.
[0031] Furthermore, the fine-tuning telescopic seat 35 is used to connect the slip ring 31 and the cutting motor 36. The fine-tuning telescopic seat 35 consists of an electric telescopic shaft and a fixed plate. The electric telescopic shaft is electrically connected to the control box 9. One end of the electric telescopic shaft is fixed to the inner wall of the slip ring 31, and the other end is connected to the fixed plate. One side of the fixed plate is connected to the cutting motor 36, thereby achieving a stable connection between the cutting motor 36 and the slip ring 31. At the same time, the cutting depth of the cutting motor 36 can be fine-tuned by adjusting the length of the electric telescopic shaft to adapt to the processing requirements of hoses with different wall thicknesses.
[0032] It should be noted that the cutting assembly 3 also includes a sensor for detecting and controlling the rotation angle of the sliding ring 31, and a photoelectric outer diameter detector for detecting the circumference of the hose. Both are electrically connected to the control box 9. The photoelectric outer diameter detector is also connected to the electric telescopic shaft to control the extension and retraction of the electric telescopic shaft, thereby facilitating adjustment and control.
[0033] In this embodiment, the main support 1 has a limiting groove 11 inside for guiding and limiting the rotation of the sliding ring 31. The limiting groove 11 has an annular groove structure and is adapted to the outer periphery of the sliding ring 31 of the cutting assembly 3. Its function is to provide guidance and limit for the rotation of the sliding ring 31, to prevent the sliding ring 31 from deviating radially or axially during rotation, to ensure that the cutting motor 36 always moves along the preset trajectory of the rubber tube circumference, and to ensure the perpendicularity and flatness of the cut.
[0034] In this embodiment, the clamping assembly 2 includes a clamping cylinder 21, a positioning clamping block 22, and a guide post 23. Furthermore, the clamping cylinder 21 is symmetrically distributed at the ends of the main support 1 and is used to drive the positioning clamping block 22 to perform telescopic movements. The positioning clamping block 22 is located at the output end of the clamping cylinder 21 and is used to clamp and position the large-diameter multi-layer steel wire reinforced tubing to be cut. The guide post 23 is located on one side of the positioning clamping block 22 and is used to guide and limit the movement of the positioning clamping block 22.
[0035] Two sets of clamping cylinders 21 operate synchronously, providing clamping power to drive the positioning clamping blocks 22 to extend and retract horizontally. This enables adaptive clamping of large-diameter, multi-layer steel wire reinforced hoses. The clamping surface of the positioning clamping blocks 22 has an arc-shaped or V-shaped groove structure adapted to the outer circumference of the hose, and a wear-resistant rubber pad is attached to the surface of the groove. The wear-resistant rubber pad can directly contact the hose to be cut. The arc-shaped or V-shaped groove structure can adapt well to hoses of different diameters. At the same time, the rubber pad can prevent damage to the outer surface of the hose and enhance friction, preventing axial or circumferential sliding of the hose during cutting and ensuring stable cutting position. The guide post 23 is inserted inside the positioning clamping block 22 to guide and limit the extension and retraction movement of the positioning clamping block 22, preventing the positioning clamping block 22 from shifting due to uneven thrust of the clamping cylinders 21. This ensures that the positioning clamping blocks 22 on both sides move towards or away from the hose synchronously, ensuring that the center of the hose is coaxial with the center of the sliding ring 31, laying the positioning foundation for subsequent annular cutting.
[0036] In this embodiment, the hose ring cutter also includes a lifting assembly 4 for controlling the height of the main support 1.
[0037] The lifting assembly 4 includes a first base 41 and a lifting mechanism 42.
[0038] Furthermore, a first base 41 is positioned below the main support 1 to support the lifting mechanism 42. The lifting mechanism 42 is positioned above the first base 41 to lift the main support 1. The first base 41 supports the main support 1 via the lifting mechanism 42. In this embodiment, the lifting mechanism 42 is preferably an electric screw jack, which is electrically connected to the control box 9, and its output end is fixed to the bottom of the main support 1. Its function is to adjust the lifting height of the lifting mechanism 42 (adjustment range 0-500mm) through the control box 9 to adapt to conveyor lines or operating tables of different heights. Simultaneously, the cutting position can be adjusted according to the placement height of the hose, ensuring that operators can complete the loading without bending over or standing on tiptoe, thus improving operational convenience.
[0039] In this embodiment, the hose ring cutter further includes a transverse movement component 5 for controlling the horizontal position of the main support 1. The transverse movement component 5 is disposed on the first base 41 and is used to drive the first base 41 to move laterally.
[0040] The lateral movement component 5 includes: a drive gear 51, a lateral movement rack 52, and a lateral movement power source 53.
[0041] Furthermore, the drive gear 51 is rotatably disposed on the lower end face of the first base 41 and meshes with the transverse rack 52. The drive gear 51 is rotatably disposed on the lower end face of the first base 41 through the bearing and meshes with the transverse rack 52, converting the rotational power of the transverse power source 53 into the transverse movement power of the first base 41.
[0042] Furthermore, the transverse rack 52 is distributed along the moving direction of the first base 41 to guide the first base 41. The transverse rack 52 cooperates with the drive gear 51 to provide guidance for the transverse movement of the first base 41. At the same time, the gear and rack transmission has the characteristics of high precision and no slippage, ensuring the accuracy of the transverse position and accurately aligning the preset cutting position of the hose.
[0043] Furthermore, the lateral movement power source 53 is disposed on the upper end surface of the first base 41 and is used to drive the drive gear 51 to rotate. In this embodiment, the lateral movement power source 53 is preferably a servo motor, which is fixed on the upper end surface of the first base 41. Its output end is connected to the drive gear 51 through a coupling to provide rotational power to the drive gear 51. The speed of the servo motor is adjusted by the control box 9 to achieve uniform lateral movement of the first base 41.
[0044] In this embodiment, the hose ring cutter also includes a longitudinal movement component 6, which is used to control the horizontal longitudinal position of the main support 1.
[0045] The longitudinal movement component 6 includes: a longitudinal movement guide rail 61, a second base 62, a moving roller 63, and a longitudinal movement power source 64.
[0046] Furthermore, the longitudinal guide rail seat 61 is used to guide the movement direction of the main support 1. The top of the longitudinal guide rail seat 61 is provided with a guide rail that is compatible with the moving roller 63, which can provide guidance for the longitudinal movement of the second base 62 and ensure the linearity of the movement trajectory.
[0047] Furthermore, the second base 62 is slidably mounted on the longitudinal guide rail seat 61. The second base 62 is connected to the transverse rack 52. The second base 62 is provided with a guide rail (not labeled in the figure) that cooperates with the transverse movement of the first base 41. It can support the first base 41 and drive the entire main support 1 to move longitudinally through its own longitudinal movement. This makes it convenient to put the sliding ring 31 on the rubber tube from the side for the cutting device to enter or exit the production line, which is convenient for equipment maintenance.
[0048] Furthermore, the movable roller 63 is mounted on the second base 62 and can roll along the extension direction of the longitudinal guide rail 61. The movable roller 63 is symmetrically installed on both sides of the bottom of the second base 62 and cooperates with the guide rail of the longitudinal guide rail 61 to reduce the friction between the second base 62 and the longitudinal guide rail 61, making the longitudinal movement smoother and more precise.
[0049] Furthermore, the longitudinal motion power source 64 is disposed on the longitudinal motion guide rail seat 61 and is used to drive the moving roller 63 to roll. In this embodiment, the longitudinal motion power source 64 is preferably a stepper motor, which is used to drive the moving roller 63 to rotate. The step distance of the stepper motor is adjusted by the control box 9 to achieve precise positioning of the second base 62.
[0050] It should be noted that the longitudinal movement assembly 6 also includes a transverse movement sensor for detecting and controlling the longitudinal movement of the second base 62. The longitudinal movement sensor is electrically connected to the control box 9 and the longitudinal movement power source 64, allowing the operator to obtain longitudinal movement data in real time, thereby facilitating the adjustment and control of the longitudinal movement distance of the second base 62.
[0051] In this embodiment, an auxiliary fume hood 7 is installed on the top of the main support 1, and a main exhaust pipe 8 is inserted through the auxiliary fume hood 7. The input end of the main exhaust pipe 8 is close to the cutting point of the cutting motor 36. A control box 9 is installed on the main support 1. The auxiliary fume hood 7 is a funnel-shaped metal cover, fixed to the top of the main support 1, with the opening covering the cutting area, used to collect diffused smoke and dust generated during the cutting process that is not collected by the main exhaust pipe 8. The main exhaust pipe 8 can accurately collect a large amount of smoke and dust generated at the cutting point of the cutting motor 36, thereby protecting the respiratory health of the operator and preventing smoke and dust from adhering to the equipment components, affecting the equipment life and polluting the working environment. The control box 9 is fixed to the side of the main support 1 and has a built-in PLC controller, touch screen and electrical components to control the overall operation of the device.
[0052] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
