Description

Technical Field

[0001] This utility model belongs to the field of tube cutting technology, specifically, it relates to a multi-line rotary cutting machine for tube processing and cutting. Background Technology

[0002] With the widespread application of electronic ceramics, optical glass, quartz materials, and high-precision tubular workpieces in the field of precision manufacturing, material slicing and processing equipment is developing towards higher efficiency, higher precision, and higher stability. Especially when processing tubular materials with small outer diameters, thin walls, or brittle materials, the processing equipment must not only ensure dimensional accuracy but also take into account rotational stability, cutting uniformity, tangential tension control, and heat dissipation capabilities.

[0003] Existing multi-wire cutting technology is mainly used for planar cutting of hard and brittle materials such as crystalline silicon and sapphire. These technologies typically use parallel arrangement of multiple wires to improve cutting efficiency, but their structural design is mainly for planar materials. When cutting cylindrical, especially hollow tubular workpieces, in a dynamic rotating state, there are obvious structural adaptation problems, making it difficult to meet actual process requirements.

[0004] Specifically, most multi-wire cutting equipment currently employs a fixed workpiece and static feed working mode. When attempting rotary cutting, even with designs that coordinate workpiece rotation with multi-wire cutting, the following key technical obstacles remain:

[0005] 1. The clamping and rotary drive mechanisms are separated, lacking integrated control: The clamping fixtures commonly used in existing equipment are mostly static structures, which are difficult to coordinate with the rotary drive mechanism. This can lead to problems such as workpiece eccentricity, jumping or slipping during rotation, which in turn affects the thickness uniformity and concentricity during the cutting process.

[0006] 2. Mismatch between the cutting line spatial path and the geometry of cylindrical workpieces: Most multi-wire devices use planar rollers to form a wire mesh tangent, which is difficult to adapt to the circumferential cutting requirements of tubular workpieces. In addition, the fixed angle of the wire makes it difficult to achieve coplanar contact between the wire mesh and the rotating tube wall, resulting in deviation of the wire entry position and uneven wire load.

[0007] Therefore, existing multi-wire cutting devices have shortcomings in terms of structural adaptability, clamping and rotation linkage capability, tangent alignment accuracy, and wire tension path management, making them unable to effectively support the cutting of high-precision, fragile tubular materials under rotation. Therefore, there is an urgent need to develop a multi-wire cutting machine capable of workpiece rotation drive, synchronous multi-wire cutting, and closed-loop tension control of the cutting wires, thereby improving the application adaptability and processing quality of multi-wire cutting technology in the processing of precision tubular materials. Utility Model Content

[0008] To address the problems of inability to achieve simultaneous rotation and cutting in existing technologies, including poor processing accuracy, stress concentration, and uneven slicing, this invention provides a multi-wire rotary cutting machine suitable for slicing tubular workpieces. This device achieves efficient coordination between workpiece rotation and multi-wire cutting by constructing an integrated tube rotation drive mechanism, a multi-wire coplanar cutting structure, a full-path tension control system, and a closed-loop take-up and unload architecture. This effectively improves cutting uniformity and processing stability. The structure enhances the adaptability and processing efficiency of multi-wire cutting technology in the processing of thin-walled, high-precision tubes.

[0009] This utility model provides a multi-wire rotary cutting machine for tube processing and slicing, including a frame, a tube worktable and a roller system; the frame has an upper and lower layer structure; the roller system is located on the upper layer of the frame and includes multiple rollers and a third drive motor to drive the rollers to rotate, the cutting wire is wound on the multiple rollers, and the area below the cutting wire is used as a cutting area;

[0010] The tube workbench is located on the lower layer of the frame and includes a lifting system for raising the tube to the cutting area and a tube installation assembly. The tube installation assembly includes a tooling bar for installing the tube, a first drive motor for rotating the tooling bar, a tube support, and a clamping mechanism. The clamping mechanism includes rotatable top blocks located at both ends of the tube support, the top blocks abutting against and clamping the tooling bar at both ends.

[0011] In a preferred embodiment, the tube is further fitted onto the outer peripheral surface of the tooling bar, and a limiting structure is provided at the junction of the top material block and the tooling bar. The limiting structure includes grooves at both ends of the tooling bar and protrusions on the top material block for embedding into the grooves.

[0012] In a preferred embodiment, the pipe support is further provided with symmetrical mounting hole pairs at both ends, and a bearing is installed in each pair of mounting holes. Each tooling bar is arranged between the mounting holes at both ends of the pipe support. One end of the top material block is a rod, and a flange is provided at the other end near the tooling bar. The rod of the top material block is nested in the corresponding bearing.

[0013] In a preferred embodiment, the clamping mechanism further includes a locking wrench, a top force block, and a nut. The top force block is located outside the top material block at one end of the tooling bar. The top force block is a T-shaped screw structure, with its top plate end abutting against the end face of the top material block and the corresponding bearing at the end. The screw portion of the T-shaped screw extends outward through the mounting hole of the tube support and is sequentially fitted with a nut and a locking wrench.

[0014] In a preferred embodiment, the tube mounting assembly further includes a timing belt, a drive wheel, and driven wheels. The driven wheels are located on the rod of the top block at the other end of the tooling bar. The first drive motor is mounted on the tube support, and its output shaft is connected to the drive wheel. The drive wheel is connected to the two driven wheels via the timing belt.

[0015] In a preferred embodiment, the system further includes a take-up and unwinding system symmetrically arranged on both sides of the lower structure of the frame. The take-up and unwinding system includes a spool and a wheel assembly. The wheel assembly is arranged to guide the cutting wire out from the spool on one side of the take-up and unwinding system, sequentially winding around the cutting path formed by the wheel assembly and the roller system, and then winding it up on the opposite spool.

[0016] In a preferred embodiment, the wheel assembly further includes a first guide wheel, a tension wheel, and a second guide wheel, wherein the first guide wheel and the second guide wheel are disposed on the side of the second support frame, wherein the first guide wheel is located above the spool on the same side, and the second guide wheel is disposed on the first support frame.

[0017] In a preferred embodiment, the take-up and undo system further includes a second drive motor, the output shaft of which is connected to the bobbin.

[0018] In a preferred embodiment, the second guide wheels on both sides of the take-up and release system are located at the same installation height and are arranged diagonally.

[0019] In a preferred embodiment, the pipe workbench further includes a workbench support, which is installed on the inner bottom surface of the lower structure of the frame; the workbench support has a lifting system mounting seat, and the lifting system is installed in the lifting system mounting seat of the workbench support.

[0020] The beneficial effects of this utility model are:

[0021] First, the multi-wire rotary cutting machine for tube processing and slicing of this utility model addresses the problems existing in the multi-wire cutting equipment, such as the inability to achieve simultaneous workpiece rotation and cutting, separation of clamping and rotation drive structures, and geometric mismatch between the cutting line path and the surface of the cylindrical workpiece. By setting up a tube worktable and integrating the lifting system and the tube installation assembly, which includes a first drive motor and a clamping mechanism, the tube can continuously rotate around its own axis while being stably clamped, and simultaneously contact the multi-wire cutting area, forming continuous slicing processing in a dynamic rotation state. This solves the problem that existing cutting equipment only supports static cutting and cannot achieve rotation processing. The clamping mechanism, through its structural limiting and rotary transmission linkage design, combined with the symmetrical positioning of the tube end, ensures the tube remains axially stable and free from relative slippage during rotation. Simultaneously, the linkage transmission between the synchronous belt and the driving / driven wheels achieves reliable and efficient torque transmission, avoiding the rotational slippage caused by tooling bars and smooth outer walls in traditional friction clamps. By using multiple rollers arranged in a non-coplanar triangular structure, the cutting wire forms an inclined winding surface in space, achieving surface-to-surface contact with the rotating tube wall. This effectively prevents wire entry angle offset, skipped wires, and wire wear, solving the technical problem of traditional guide rollers making it difficult for the tangent to be coplanar with the cutting surface, thus improving the bonding efficiency and cutting uniformity of multi-wire cutting. The wire feeding and take-up system is located on the left and right sides of the lower layer of the frame, including symmetrically arranged spools, guide roller groups, and a tensioning mechanism. The cutting wire is released from one spool, guided, passes around the tensioning roller, enters the roller system to form the cutting area, and is finally retrieved and wound from the opposite side, forming a closed-loop tensioning path structure. This structure can continuously adjust the line tension to adapt to workpiece disturbances or changes in line speed, solving the hidden dangers of non-closed tension paths and uncontrolled line tension in existing devices.

[0022] Secondly, in the preferred implementation, this utility model sets a U-shaped pipe support in the pipe installation assembly, with symmetrical mounting holes at both ends. The top block is inserted into the hole and clamps the tooling bar, which realizes rapid positioning and stable clamping of the pipe, improving vibration resistance and adaptability. The combination of the top block, nut and locking wrench enables the clamping device to have a quick adjustment and locking function, preventing loosening of the clamp. In addition, by setting a driven wheel on the top block rod at one end of the tooling bar, and cooperating with the first drive motor, drive wheel and synchronous belt installed on the pipe support to form a rotary drive structure, it is effectively ensured that the pipe is not eccentric or shaking during rotation and that the torque is transmitted evenly.

[0023] Third, in the preferred implementation, this utility model sets the second guide wheels on both sides of the take-up and release system at the same installation height and arranged diagonally, so that the cutting wire can form a symmetrical and stable spatial conductor path when it crosses both sides, effectively preventing the cutting wire from being misaligned, intersecting, or having inconsistent wrap angles before being introduced into the roller system, thereby improving the consistency of multi-wire introduction and the overall uniformity of the cutting surface.

[0024] Fourth, in the preferred implementation, the outer envelope surface formed by the three rollers of this utility model is provided with a spiral groove extending along the axial direction, so that multiple cutting wires can be evenly distributed along a preset spiral path and embedded in the groove during the winding process. This structure not only effectively prevents the cutting wires from sliding or misaligning laterally during high-speed movement, but also guides the cutting wires to build a stable spiral cutting surface with a constant spacing and trajectory.

[0025] Fifth, in the preferred embodiment, the roller of this utility model adopts a hollow metal roller structure and is provided with a wear-resistant coating or ceramic spray coating on its surface, which improves its surface hardness and wear resistance. During the high-speed winding operation of the cutting line, it effectively reduces wear and heat accumulation caused by friction and extends the service life of the roller.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions of this application, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] The directional terms such as above, below, left, right, front, and back used in this application are based on the positional relationships shown in the attached drawings. Different attached drawings may result in different positional relationships, therefore they should not be interpreted as limitations on the scope of protection.

[0035] In this application, the terms "installation," "connection," "interlocking," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, or a connection that allows communication between components. They can also refer to a direct connection or an indirect connection through an intermediate medium. They can refer to the internal connection of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0036] In the process of multi-wire cutting of high-precision tubular workpieces such as electronic ceramics and quartz glass, this application found that the tubular material itself has typical structural characteristics such as hollowness, thin walls, small outer diameter, and high brittleness. This causes a series of problems to be exposed when processing such workpieces using traditional fixed-workpiece, static-feed multi-wire cutting methods, such as cutting stress concentration, local heat accumulation due to constant tangent entry point, machining eccentricity, and mismatch between the cutting path and the tube wall geometry, which seriously affect the cutting accuracy and finished product quality. To address this, this application proposes a multi-wire rotary cutting machine for tube material processing. By introducing an integrated clamping-rotation-feed mechanism on the cutting platform, the tube material can enter the cutting area in a rotating state, achieving synchronous multi-wire cutting. In addition, through innovative tangent guide structure and arrangement angle, the device described in this application can effectively improve the fit between the tangent and the tube wall, achieve dynamic coplanar matching between the cutting path and the tube geometry, and improve cutting quality and processing stability by combining a closed-loop tension control system and a high-efficiency chip removal and heat dissipation module, thus solving the adaptability bottleneck of existing multi-wire cutting equipment when processing tubular workpieces.

[0037] Example 1

[0038] As per the instruction manual Figure 1 A multi-wire slicing machine for tube processing includes a frame 1, a tube worktable 2, a take-up and undo system 3, and a roller system 4. The frame 1 has a double-layer structure; the upper layer houses the cutting execution components, and the lower layer houses the auxiliary transmission and control mechanisms. A through-hole opening is provided between the upper and lower layers for the tube to pass through. The roller system 4, located within the upper layer of the frame 1, is the core cutting component of this multi-wire slicing machine. The take-up and undo system 3 is symmetrically positioned on the left and right sides below the roller system 4 within the lower layer of the frame 1. Each side has a bobbin, a tension control unit, and a guide wheel assembly to form a complete take-up and undo channel. The cutting wire emerges from the spool of the take-up and unwind system 3 on one side, passes through the guide mechanism, and enters the roller system 4. It winds around multiple rollers to form a multi-wire parallel cutting area, enabling simultaneous multi-faceted cutting of the tube. After passing through the rollers, the cutting wire is retrieved from the take-up and unwind system 4 on the opposite side, achieving closed-loop guidance and ensuring the cutting wire remains taut and runs smoothly. The tube worktable 2 is located in the lower structure of the frame 1, directly below the roller system 4. The tube worktable 2 includes a lifting system and a rotating system that drives the tube to be processed. The tube and the rotating system are integrally mounted on the lifting system. During operation, the tube passes through the opening between the upper and lower structures via the lifting system, enters the cutting area, and is raised to the height of the cutting wire. Simultaneously, it rotates synchronously under the action of the rotating system, achieving slicing.

[0039] As per the instruction manual Figure 2 In the implementation of this application, the upper-layer architecture of rack 1 is as follows: Figure 2The first support frame 10 shown, the lower structure of the rack 1 is as follows: Figure 2 The second support frame 11 shown together constitutes the basic load-bearing and installation platform of the entire machine. The first support frame 10 and the second support frame 11 employ reinforcing ribs and rigid corner connections to construct a high-strength platform, ensuring that the structure does not deform during high-speed cutting, thereby maintaining cutting accuracy. Both the first support frame 10 and the second support frame 11 are rectangular frames, with the first support frame 10 aligned along one side of the second support frame 11. The two frames are rigidly connected by high-strength bolts, and diagonal reinforcing ribs are installed at each connection node to suppress lateral and torsional deformation.

[0040] The roller system 4 includes at least three rollers 40 and a third drive motor 41 connected to them. (See attached instruction manual.) Figure 3 As shown, three rollers 40 are arranged in a triangle along the axial direction, with their central axes parallel to each other, forming a non-coplanar support structure at three spatial points. The outer envelope of this non-coplanar support structure is the winding surface of the cutting line. The first support frame 10 has corresponding mounting holes on both sides according to the arrangement of the three rollers 40. Each mounting hole contains a bearing, and both ends of each roller 40 are mounted in the corresponding mounting holes and rotatably connected to the bearings. A third drive motor 41 is installed at the same end of each of the three rollers 40, driving the rollers 40 to rotate.

[0041] Furthermore, roller 40 is a hollow metal roller structure with a wear-resistant coating or ceramic spraying on its surface to improve the wear resistance and tensile strength at the contact point between the cutting line and the roller. On the outer envelope formed by the three rollers 40, a spiral groove is formed along the axial direction, and this spiral groove is a continuous winding path.

[0042] In the implementation of this application, the take-up and release system 3 also includes a second drive motor 30. A mounting plate is provided on each of the left and right sides of the bottom of the second support frame 11, and a second drive motor 30 is fixedly mounted on each mounting plate. Since the take-up and release system 3 has a symmetrical structure design, one side will be used as an example for explanation. The output shaft of the second drive motor 30 passes through the mounting plate and connects to the corresponding spool 31. The central axes of the second drive motor 30 and the spool 31 are arranged horizontally, realizing active take-up and release control of the cutting wire.

[0043] The tension control unit includes a tensioning wheel 33 and a swing arm mechanism. The swing arm mechanism includes a swing arm body and a return spring. The swing arm body is a rigid connecting arm made of high-strength aluminum alloy or structural steel. One end of the swing arm body is connected to the side of the second support frame 11 via a pivot, allowing it to swing within a certain angle range around the pivot. The other end is equipped with the tensioning wheel 33, which moves with the rotation direction of the swing arm to adjust the length and tension of the cutting line. The length of the swing arm body is set according to the installation space and tension accuracy requirements. One end of the return spring is fixed to the middle or near the bottom of the swing arm body, and the other end is fixed to the second support frame 11. The return spring always pulls the swing arm downwards or backwards, ensuring that the swing arm body always applies tension in the direction of the cutting line.

[0044] The guide wheel assembly of the take-up and undo system 3 includes a first guide wheel 32 and a second guide wheel 34. The first guide wheel 32 is installed on the side of the second support frame 11 and above the corresponding spool 31. The central axis of the first guide wheel 32 intersects perpendicularly with the central axis of the spool 31, forming a first guide turning point. After the cutting wire exits from the spool 31, it wraps around the first guide wheel 32 at an approximately 90° wrap angle, completing the direction change. After the cutting wire is led out from the first guide wheel 32, it enters the tension wheel 33 area and completely wraps around the tension wheel 33 at a 180° wrap angle. The tension wheel is installed at the end of the swing arm mechanism to actively absorb line length fluctuations and maintain a constant tension state. The second guide wheel 34 is installed on the first support frame 10, located below the bottom of the cutting envelope structure formed by the three rollers 40. Its mounting axis is set to have a certain inclination angle relative to the horizontal plane, and this inclination angle is tangent and coplanar with the triangular cutting envelope surface formed by the three rollers 40. After the cutting line wraps around the second guide roller 34 at a 90° angle, it is naturally guided into the roller system to form the cutting surface. The second guide roller 34 plays a role in direction correction, path fine-tuning, and layer transition, so that the cutting line enters the spatial cutting surface formed by the three rollers 40 precisely.

[0045] Figure 2 The arrows indicate the direction of movement of the cutting wire. The cutting wire exits from the spool 31, and its path includes a 90° wrap angle around the first guide roller 32, a 180° wrap angle around the tension roller 33, and another 90° wrap angle around the second guide roller 34, finally entering the inclined triangular cutting surface formed by the three rollers 40, forming a spiral winding path. After cutting, it enters the take-up and unwinding system on the other side for symmetrical recovery. It should be noted that in this application, the second guide rollers 34 on both sides of the take-up and unwinding system 3 are arranged diagonally on the same mounting surface to ensure that the cutting wire does not cross or experience tension fluctuations in the crossing structure.

[0046] As per the instruction manual Figure 4The pipe loading workbench includes a workbench support 20, a lifting system 21, and a pipe loading assembly 22. The workbench support 20 is mounted on the bottom surface of the second support frame 11 and is located on the symmetrical center lines of both sides of the take-up and unwinding system 3. The workbench support 20 is provided with a lifting system mounting seat, in which the lifting system 21 is mounted. The pipe loading assembly 22 is mounted on top of the lifting end of the lifting system 21.

[0047] Specifically, the lifting system 21 includes a servo motor, a coupling, a ball screw, a screw nut seat, a bearing seat with bearings, a linear guide rail, and a slider. The servo motor is fixed to the lower outer side of the worktable support 20, and its output shaft is connected to the ball screw via the coupling. The coupling, ball screw, screw nut seat, and bearing seat with bearings are located in the lifting system mounting base of the worktable support 20. Both ends of the ball screw are supported in the lifting system mounting base by the bearing seats with bearings, converting the rotational motion of the servo motor into linear propulsion. The screw nut seat is sleeved on the screw, and ball bearings are rotatably connected to the screw. One side of the screw nut seat is connected to one side of the slider, and the other side of the slider is slidably connected to the guide rail inside the lifting system mounting base. The servo motor drives the ball screw to rotate, and the rotation of the ball screw drives the slider fixed on the screw nut seat to move up and down along the guide rail inside the lifting system mounting base.

[0048] As per the instruction manual Figure 5-6The pipe installation assembly 22 includes a pipe support 228, a pipe 224, a pipe clamping assembly, a first drive motor 225, a synchronous belt 226, a driven pulley 227, and a drive pulley. The pipe support 228 is a U-shaped frame with symmetrical mounting holes at both ends for mounting the pipe clamping assembly. Each pair of mounting holes contains a bearing. The bottom of the U-shaped structure is connected to the top of the ball screw of the lifting system 21 by screws or keys. The pipe clamping assemblies are symmetrically arranged on both sides of the pipe support 228. Each clamping assembly is located in the through holes at both ends of the support 228. The pipe clamping assembly includes a locking wrench 220, a lifting block 221, a lifting block 222, and a tooling bar 223. Taking the pipe clamping assembly on one side as an example, the tooling rod 223 is disposed between the mounting holes at both ends of the U-shaped structure. The tooling rod is made of elastic material with cut resistance. The outer circumferential surface of the tooling rod 223 is coated with an adhesive layer. The pipe 224 is fitted onto the outer circumferential surface of the tooling rod 223 for fixation. Ejector blocks 222 are provided in the mounting holes at both ends of the U-shaped structure. Two ejector blocks 222 are clamped at both ends of the tooling rod 223. The tooling rod 223 has grooves at both ends, and the ends of the ejector blocks 222 that contact the tooling rod 223 have protrusions. The grooves at both ends of the tooling rod 223 are engaged by the protrusions of one ejector block 222, preventing slippage between the ejector blocks 222 and the tooling rod 223 during the rotation driven by the first drive motor 225. A flange is provided at one end of the ejector block 222 closest to the tooling rod 223, and a rod is provided at the other end. The rod of the ejector block 222 is nested in a corresponding bearing to achieve rotational support.

[0049] A lifting block 221 is provided on the outer end face of the top material block 222 located at one end of the tooling bar 223. The lifting block 221 is a T-shaped screw structure, and its top plate end abuts against the end face of the top material block 222 and the corresponding bearing. The screw part of the T-shaped screw extends to the outside through the mounting hole of the pipe support 228, and is fitted with a nut and a locking wrench 220 in sequence. By tightening the nut and the locking wrench 220, the rotation axis of the lifting block 221 is kept collinear with the central axis of the top material block 222 and the tooling bar 223, so as to realize the axial locking and fixing of the top material block 222 and the tooling bar 223 and the quick disassembly and replacement of the pipe 224 to be processed.

[0050] A driven wheel 227 is fitted onto the rod of the top block 222 located at the other end of the tooling bar 223. A first drive motor 225 is mounted at the bottom of the tube support 228, and its output shaft is connected to the drive wheel via a coupling. The drive wheel is positioned between the two driven wheels 227. A synchronous belt is wound around the drive wheel and the two driven wheels 227. The first drive motor 225 drives the drive wheel to rotate, which in turn drives the two driven wheels 227 to drive the top block 222, tooling bar 223, and tube 224 to achieve synchronized rotation.

[0051] In this implementation, to ensure that the cutting wires and the tube material do not deform, burn, or suffer material damage due to frictional heat during high-speed cutting, the multi-wire slicing machine for tube material processing also includes a cooling system 5. The cooling system 5 is installed on the first support frame 10 and located above the tube material cutting area. The cooling system 5 includes a cooling nozzle assembly, a fluid supply pipeline, a solenoid valve, a liquid storage tank, a cooling controller, and a mounting plate. The mounting plate is installed on the upper structural beam of the first support frame 10, and is securely connected to the frame structure by screws or welding to form an independent support interface. Each nozzle in the cooling nozzle assembly is evenly distributed along the bottom of the mounting plate and fixed to the mounting plate using threaded connectors or snap-fit ​​quick-release seats. Each nozzle has a liquid inlet, connected to the fluid supply pipeline via a hose, with the nozzle outlet facing downwards towards the cutting area. The fluid supply pipeline uses a pressure-resistant high-temperature hose or a metal corrugated pipe, with one end connected to the liquid inlets of multiple nozzles and the other end converging to the solenoid valve. Preferably, a "T-type splitter" or "distribution manifold" is used to split and connect a single fluid supply line to multiple nozzles. Each branch is equipped with a throttle valve or flow limit port to allow for individual flow regulation of each nozzle. The fluid supply pipeline is arranged along the back of the mounting plate and is fixed with pipe clamps or clips to prevent loosening due to vibration.

[0052] The storage tank is mounted on frame 1 and connected to the inlet of the solenoid valve via a fluid delivery hose. The storage tank stores coolant or connects to an external coolant circulation system. The solenoid valve is mounted on the mounting plate or near the storage tank, with its inlet connected to the tank outlet and its outlet connected to the fluid supply line. It is also connected to the signal port of the cooling controller via a signal line for remote on / off control. The solenoid valve receives on / off signals from the cooling controller and controls the liquid flow under set conditions, enabling switching between intermittent and continuous spray modes. The cooling controller connects to the solenoid valve and motor system, outputting control commands via a signal line to receive temperature sensor or time-based logic trigger commands to start or stop the spraying action. The cooling controller allows setting parameters such as spray interval, spray duration, and automatic start / stop conditions, and supports PLC or HMI integration, allowing it to be integrated into the overall equipment control system.

[0053] In the implementation of this application, in order to realize the automatic monitoring and response of loading, positioning or unloading of pipe workpieces after slicing, the multi-line rotary cutting machine for pipe processing and slicing also includes a transfer induction plate and a transfer sensor to realize the identification and feedback of a key position of the pipe in the lifting path.

[0054] Specifically, the transplanting induction plate is installed on the pipe support 228, using a metal sheet, reflective sheet, or magnetic sheet as the target trigger. The transplanting sensor is mounted on the frame 1, its position precisely arranged according to the detection purpose, ensuring that it can pass through the set sensing point during the lifting stroke. It uses a photoelectric sensor, Hall sensor, or inductive proximity switch, paired with the transplanting induction plate, to provide non-contact detection capability. The transplanting sensor is connected to the main control system of the equipment to provide position signal input. In this application, two sets of transplanting sensors and transplanting induction plates are provided, one set for sensing the rising point of the lifting system 21, and the other set for sensing the falling point of the lifting system 21. When the lifting system 21 moves the pipe 224 up or down, the induction plate moves accordingly. When the induction plate passes through the detection area where the transplanting sensor is located, the sensor triggers a signal output. After receiving the trigger signal, the main control system performs the following operations: determines whether the tube has reached the designated processing position (e.g., the cutting surface); determines whether the lifting has reached the upper or lower limit, triggering an emergency stop or protection; determines whether the workpiece has been processed and moved to the transfer position, and links the robot or feeding mechanism to unload the material.

[0055] The working principle of the multi-wire slicing machine for tube processing and slicing in this application is as follows:

[0056] The cutting wire exits from the spool 31 on one side of the take-up and unwinding system 3, passing sequentially around the first guide roller 32, the tension roller 33, and the second guide roller 34 to form a segmented guide path. Through the elastic action of the swing arm mechanism, the tension roller 33 applies continuous tension to the cutting wire, achieving automatic tension adjustment and maintaining stable cutting wire operation. After being led out by the second guide roller 34, the cutting wire enters the roller system 4 and winds around the triangular outer envelope formed by three rollers 40 in a spiral path. The rollers 40 are driven to rotate unidirectionally by the third drive motor 41, causing the cutting wire wound on their surface to form a continuously rotating multi-line cutting surface. The tube 224 is mounted on the tube support 228 via a tube clamping assembly, and the tube support 228 is mounted on the lifting end of the lifting system 21. The lifting system 21 consists of a servo motor, coupling, ball screw, and other components, driving the tube 224 to rise and fall vertically with the slide table and accurately enter the cutting wire winding area. After the material is raised to the correct position, the first drive motor 225 starts, driving the drive wheel to rotate via the synchronous belt 226, which in turn drives the driven wheel 227 to rotate, thus causing the top block 222, tooling bar 223, and tube 224 to rotate synchronously as a whole. At this time, the tube 224 and the cutting wire in dynamic cutting state form a spiral contact in space, achieving efficient and uniform slicing. The cut wire enters the opposite side of the take-up and unwinding system 3 and is wound up on the spool 31, forming a complete closed loop. This ensures the continuous and efficient repetitive operation of the cutting wire, adapting to continuous processing requirements.

As shown in Table 1:

[0062] This utility model discloses a multi-wire rotary cutting machine for tube processing and slicing. By integrating a tube worktable, it achieves the integration of the lifting system and the tube installation components. The tube is stably clamped and continuously rotates around its own axis under the action of the first drive motor and clamping mechanism, synchronously contacting the multi-wire cutting area to form continuous slicing processing in a dynamic rotating state, solving the problem of traditional equipment only being able to cut statically. The clamping mechanism adopts a U-shaped tube support structure with symmetrical mounting holes at the ends. A top force block, nut, and locking wrench enable quick positioning and locking. The drive wheel, driven wheel, and synchronous belt provide a reliable rotary drive, ensuring axial stability and balanced torque during tube rotation. Multiple rollers are arranged in a non-coplanar triangular pattern, with spiral grooves on the outer envelope, allowing the cutting wires to wrap evenly and embed into the grooves, forming a stable spiral cutting surface. This effectively avoids lateral slippage, skipping, and wear of the cutting wires, while improving bonding efficiency and cutting uniformity. The rollers are made of hollow metal shafts with wear-resistant coatings or ceramic spraying treatment to improve wear resistance and heat dissipation performance, extending service life. The wire feeding and take-up system is symmetrically positioned on both sides of the lower layer of the frame. It forms a closed-loop tensioning path through spools, guide rollers, and a tensioning mechanism. The wire is released from one side, guided and tensioned, then wound around a roller before being retracted to the opposite side for winding. Continuous tension adjustment ensures stable wire speed and avoids the risk of tension runaway. Furthermore, the second guide rollers are diagonally symmetrically arranged at the same height, effectively preventing misalignment or interference of the cutting wires before they are introduced, further improving the consistency of multi-wire introduction and the overall quality of the cut surface. This comprehensively optimizes the dynamic rotation of the workpiece, path matching, and machining accuracy control during multi-wire cutting. In addition, an integrated cooling system is installed above the cutting area, using directional spray from nozzles to cool the wires, suppressing high-temperature accumulation, reducing wire wear, and improving the continuity of the cutting process and the quality of the slices.
