Description

Technical Field

[0001] This invention relates to the field of metal shearing machine tool technology, and in particular to an integrated machine and method for centering, gathering, and preventing the collapse of waste steel wire coils into a cage-type protective cutting mechanism. Background Technology

[0002] Waste steel wire coils are a large quantity of scrap metal materials generated in industrial production, construction, and manufacturing. They come from a wide range of sources and are produced in huge quantities. During use and storage, waste steel wire coils are usually loose, deformed, and have irregular cross-sections due to external forces or failure of binding. The steel wire coils are arranged in a disordered manner and cannot maintain their original tight coil shape.

[0003] The recycling and reuse of waste steel wire coils typically involves core processes such as gathering and shaping, centering and positioning, and cutting into segments for subsequent smelting, packaging, or transportation. However, existing technologies have the following prominent problems in these processes: I. Difficulty in centering and gathering loose wire coils: Existing coil clamping devices mostly use an integrated fixed cone sleeve, which achieves centering by applying pressure to the end face of the coil through the cone surfaces at both ends. This structure has a fixed cone angle and can only adapt to regular coils of specific specifications. When dealing with loose, deformed, or uneven scrap wire coils, the wire coils are difficult to automatically return to their original position during the clamping process, resulting in poor centering and easily causing clamping deviation or clamping failure.

[0004] 2. One-time clamping is not effective in straightening loose coils: Due to the loose layers of waste steel wire coils, when traditional clamping mechanisms apply pressure and clamp at one time, the steel wire coils are subjected to uneven force, and the inner steel wires cannot be synchronously gathered with the outer steel wires, resulting in insufficient shaping. There are still disorder and gaps inside the steel wire coil, which affects the stability of subsequent processing.

[0005] 3. The problem of steel wire breakage during the cutting process is prominent: When waste steel wire coils are axially sheared into sections, the steel wire itself has strong elastic energy storage. At the moment of cutting, the steel wire is easy to bounce and break apart in all directions. This not only poses a serious safety hazard, but also causes the material to scatter and be difficult to collect, requiring additional manual sorting and greatly reducing production efficiency.

[0006] Fourth, the gathering and shearing processes are fragmented, resulting in low equipment utilization: In the existing process, the gathering, shaping and shearing of waste steel wire coils are usually completed in steps on different equipment. The workpieces need to be transferred and repositioned multiple times, which is cumbersome, time-consuming, and requires a large amount of equipment space, resulting in low overall processing efficiency.

[0007] In summary, the existing technology lacks a machine tool that can adapt to the radial gathering and centering of loose waste steel wire coils, adaptive clamping of multiple specifications, and can complete the gathering positioning and shearing anti-split functions on the same shearing processing equipment. Summary of the Invention

[0008] The technical problem this invention aims to solve is: to address the issues of fragmented processes in the recycling and processing of waste steel wire coils, requiring multiple machines to complete the steps, and the easy scattering and splashing of steel wire during cutting. This invention provides an integrated machine and method for centering, centering, and preventing scattering of waste steel wire coils using a cage-like protective cutting system. By having two coaxially opposite variable working surfaces form a conical gathering surface in the first working state (axial angle < 90°), the loose waste steel wire coil is radially gathered and centered. In the second working state (axial angle > 90°), multiple sets of rods forming the variable working surfaces on both sides are interleaved and inserted to form a cage-like structure. This cage-like structure simultaneously serves as the feed guide groove for the cutting blade and a 360° external constraint to prevent the steel wire from scattering, achieving integrated continuous operation of gathering and shaping, centering and positioning, and shearing and scattering prevention on the same cutting processing equipment.

[0009] The technical solution adopted by this invention to solve its technical problem is: a waste steel wire coil centering and anti-collapse cage-type protective cutting integrated machine, comprising: frame; Two sets of horizontal cylinders are coaxially mounted on the frame and driven by a drive mechanism to move closer or further apart from each other along the axial direction. The combined rod unit is respectively disposed on the two sets of cross cylinders. Each combined rod unit consists of several rods hinged to the side wall of the cross cylinder near the end and distributed along the circumference of the cross cylinder. The rods on the same cross cylinder are evenly spaced around the axis of the cross cylinder, and the angle between each rod and the cross cylinder is adjusted by an angle adjustment mechanism so that the rods form a variable-shaped working surface. The rods on the two sets of cross cylinders are staggered in the circumferential direction, and the distance between two adjacent rods on the same cross cylinder is greater than the width of a single rod. A central shaft is coaxially arranged with two sets of horizontal cylinders. One end of the central shaft is fixedly connected to the end face of one set of horizontal cylinders, and the other end can be slidably inserted into the port of the other set of horizontal cylinders. The waste steel wire roll is mounted on the central shaft. When the central shaft is used to pick up or put down the steel wire roll, it is only necessary to pull out the sliding end of the horizontal cylinder along the axial direction to expose the central shaft and put the steel wire roll on or take it off. A cutting mechanism is mounted on the frame. The cutting blade of the cutting mechanism is a strip-shaped shearing blade, which is driven by a cutting drive to feed along a straight path and cut the steel wire coil sleeved on the central shaft. The combined rod unit has both workpiece clamping and shearing protection functions, forming the workpiece clamping and protection accessories of the shearing machine.

[0010] The all-in-one machine has a first working state and a second working state: In the first working state, the included angle between each of the rods and the cross cylinder is less than 90°, and each of the rods forms a conical working surface. When the two sets of cross cylinders approach each other, the conical working surface clamps the end face of the waste steel wire roll from both ends, and radially gathers and axially centers and positions the loose steel wire roll. In the second working state, the angle between each of the rods on the two sets of horizontal cylinders and the horizontal cylinder is greater than 90°. The rods on the two sets of horizontal cylinders are inserted into each other in an alternating manner, forming a cage-like structure that covers the outside of the waste steel wire roll. The cutting blade of the cutting mechanism feeds along the gap between the rods to perform shearing. The cage-like structure binds the steel wire from the outside to prevent the cut steel wire from breaking apart.

[0011] This solution constructs the rods at the ends of the cross cylinder as an adjustable hinged assembly. In the first working state, the same set of combined rod units encloses and forms a conical working surface, which radially gathers and axially centers the loose and deformed waste steel wire coils. In the second working state, they flip and interlock to form a cage-like structure, which simultaneously undertakes the functions of shearing feed guide and anti-breakage protection. This achieves the integrated processing of four functions—gathering and shaping, centering and positioning, shearing guidance, and anti-breakage protection—on a single shearing processing equipment. It eliminates the auxiliary time of multiple workpiece transfers and repositioning in traditional processes, and significantly improves the efficiency of waste steel wire coil shearing and recycling.

[0012] In some embodiments, an axially extending groove is formed on the outer circumferential surface of the central shaft, and the position of the groove in the circumferential direction corresponds to the position of the gap between the rods formed after the rods on the two sets of cross cylinders are inserted alternately. The width of the groove is greater than or equal to the thickness of the cutting blade, and when the cutting blade feeds along the gap between the rods, the cutting edge extends into the groove.

[0013] By creating a cutting groove on the outer circumference of the central shaft corresponding to the gap between the rods, the cutting blade can smoothly extend into the cutting groove as it feeds along the gap between the rods, allowing the blade to penetrate the entire radial thickness of the wire coil and achieve complete cutting of the wire coil.

[0014] In some embodiments, as the driving mechanism drives the two sets of horizontal cylinders to approach each other along the axial direction, it also drives the two sets of horizontal cylinders to perform small-amplitude reciprocating motion along the axial direction, so that the combined rod units on the two sets of horizontal cylinders alternately apply clamping force and releasing force to the two end faces of the waste steel wire roll, causing the loose steel wire to return to center layer by layer.

[0015] Due to long-term storage and transportation, waste steel wire coils exhibit varying degrees of looseness between layers and misalignment of the wire coils. This solution utilizes a drive mechanism that employs superimposed reciprocating motion as the cross-section approaches, causing the combined rod unit to apply periodically varying clamping force to the end face of the steel wire coil: during the clamping phase, the outer layer of steel wire is driven to retract inward; during the release phase, the inner layer of steel wire gains a small space for misalignment and rearranges under the influence of gravity and elastic restoring force; after multiple cycles, the loose steel wire gradually returns to its original position from the outside in, achieving full shaping of the steel wire coil from the surface to the core.

[0016] In some embodiments, the angle adjustment mechanism includes an angle adjustment ring slidably fitted onto the cross cylinder and a linkage rod hinged between each of the rods and the angle adjustment ring. When the angle adjustment ring slides along the axial direction of the cross cylinder, it drives each of the rods to rotate synchronously around the hinge point via the linkage rod, thereby adjusting the angle between each rod and the cross cylinder. The axial sliding of the angle adjustment ring can drive all the rods to rotate synchronously and at the same angle, achieving rapid switching of working states.

[0017] A method for centering, gathering, and preventing collapse of waste steel wire coils during cutting includes the following steps: The waste steel wire roll is placed on the central shaft, which is located between two sets of horizontal cylinders; The two sets of horizontal cylinders are driven to approach each other along the axial direction, and the included angle between each rod and the horizontal cylinder is kept less than 90°. The combined rod unit encloses and forms a conical working surface. The two sets of conical working surfaces clamp the end face of the waste steel wire roll from both ends. During the process of the horizontal cylinders approaching each other, the conical surface will gather the loose steel wires radially towards the center layer by layer, and make the axis of the steel wire roll automatically align with the axis of the horizontal cylinder. Continue to drive the two sets of horizontal cylinders to approach each other along the axial direction to a predetermined position. Adjust the included angle between each rod and the horizontal cylinder to greater than 90° through the angle adjustment mechanism. The rods on the two sets of horizontal cylinders are arranged in an alternating manner in the circumferential direction and inserted into each other to form a cage-like structure covering the outside of the waste steel wire roll. The drive cutting blade feeds linearly along the gap between adjacent rods to axially shear the waste steel wire roll. During the shearing process, the cage-like structure binds the waste steel wire roll from the outside, and the cut steel wire is intercepted by the rods to prevent it from breaking outward.

[0018] The beneficial effects of this invention are: 1. In the first working state (angle < 90°), the same combined rod unit encloses and forms a conical working surface to radially gather and axially center the loose waste steel wire coil; in the second working state (angle > 90°), it flips and interlocks to form a cage-like structure, simultaneously serving as the shearing feed guide and anti-breakage protection function. From the moment the waste steel wire coil is placed to the completion of shearing, the entire process is completed continuously on the same shearing processing equipment, eliminating the need for transfer and repositioning between different devices.

[0019] 2. The cage-like structure formed by the interlocking rods wraps and binds the entire roll of steel wire 360° from the outside before shearing occurs. When the scrap steel wire is cut, the internal bending elastic deformation is released instantly, and the breakage force is directly intercepted by the rods. The anti-breakage function requires no additional parts or costs.

[0020] 3. The feed channel of the cutting blade is formed by utilizing the geometric gap between adjacent rods after they are axially connected, thus realizing the structural reuse of guiding and clamping functions. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

They are used solely for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Example 1: like Figures 1-6 The image shown is an embodiment of the present invention, a cage-type protective cutting machine for centering, gathering and preventing collapse of waste steel wire coils, including a frame 1, two sets of horizontal cylinders 2, a combined rod unit 3, a central shaft 4, a cutting mechanism 5, a driving mechanism 6, and an angle adjustment mechanism 7. The integrated machine in this embodiment belongs to the metal shearing and processing machine tool and is used to shear and segment rolled waste metal materials.

[0032] In this embodiment, the frame 1 serves as the load-bearing foundation of the entire equipment and is constructed from welded or cast steel. Drive mechanisms 6 are symmetrically arranged on the left and right sides of the frame 1. Two sets of horizontal cylinders 2 are respectively mounted on the two sets of drive mechanisms 6, coaxially distributed at both ends of the waste steel wire roll. The two sets of drive mechanisms 6 guide the axial movement of the two sets of horizontal cylinders 2, allowing them to move closer or further apart. The drive mechanism 6 can be any one of a screw-nut mechanism, a hydraulic cylinder mechanism, or an electric push rod mechanism. The horizontal cylinder 2 is a hollow cylindrical structure, with the end closer to the waste steel wire roll as the working end and the end further away as the mounting end, which is fixedly connected to the drive end of the drive mechanism 6.

[0033] In this embodiment, the combined rod unit 3 is disposed at the working end of the cross cylinder 2. The combined rod unit 3 consists of several rods 31 hinged to the circumference of the end of the cross cylinder 2. Specifically, several hinge seats 21 are uniformly provided circumferentially on the end face of the cross cylinder 2 near the working end. The root of each rod 31 is hinged to the hinge seat 21 through a hinge shaft, so that each rod 31 can rotate around the hinge shaft in a plane perpendicular to the axis of the cross cylinder 2. The rods 31 on the same cross cylinder 2 are evenly spaced around the axis of the cross cylinder 2, and the included angle between adjacent rods 31 is equal. The rods 31 are long strips, and their length is greater than the radius of the waste steel wire coil, and they can be made of high-strength steel.

[0034] In an embodiment, such as Figures 5-6As shown, the rods 31 on the two sets of horizontal cylinders 2 are staggered in the circumferential direction: that is, the rods 31 on the left horizontal cylinder 2 and the rods 31 on the right horizontal cylinder 2 are offset from each other in the circumferential direction. At the same time, the distance between two adjacent rods 31 on the same horizontal cylinder 2 is greater than the width of a single rod 31, to ensure that the rods 31 on the two sets of horizontal cylinders 2 can be interleaved and inserted without interference after being flipped. The angle between each rod 31 and the horizontal cylinder 2 is adjusted by the angle adjustment mechanism 7. The angle adjustment mechanism 7 includes an angle adjustment ring 71 slidably fitted on the outer wall of the cross cylinder 2 and a linkage rod 72 hinged between each rod 31 and the angle adjustment ring 71. The angle adjustment ring 71 is an annular sleeve that is slidably fitted on the outer peripheral wall of the cross cylinder 2 and can slide along the axial direction of the cross cylinder 2. One end of the linkage rod 72 is hinged to the end face of the angle adjustment ring 71, and the other end is hinged to the middle or near the root of the corresponding rod 31. When the angle adjustment ring 71 slides along the axial direction of the cross cylinder 2, the linkage rod 72 drives each rod 31 to rotate synchronously around the hinge axis, thereby adjusting the included angle between each rod 31 and the cross cylinder 2. A driving component 73, such as a hydraulic cylinder / electric push rod, is provided between the angle adjustment ring 71 and the mounting end of the cross cylinder 2. The angle adjustment ring 71 is connected to the telescopic end of the driving component 73. The telescopic movement of the driving component 73 is used to move the angle adjustment ring 71 to the desired position, thereby controlling the included angle of the rod 31.

[0035] In this embodiment, the central shaft 4 is coaxially arranged with two sets of cross cylinders 2 for threading the scrap steel wire roll. One end of the central shaft 4 (e.g., the right end) is fixedly connected to the end face of one set of cross cylinders 2 (the right cross cylinder 2) (e.g., by flange bolts or welding), while the other end (the left end) is slidably inserted into the port of the other set of cross cylinders 2 (the left cross cylinder 2). The outer diameter of the central shaft 4 is slightly smaller than the inner diameter of the scrap steel wire roll so that the scrap steel wire roll can be smoothly fitted onto the central shaft 4. The central shaft 4 is made of high-strength alloy steel to withstand the cutting force during shearing and the radial pressure of the steel wire roll.

[0036] In this embodiment, the cutting mechanism 5 is mounted on the frame 1 and located above the central axis 4, for cutting the waste steel wire roll axially. The cutting blade 51 of the cutting mechanism 5 is a strip-shaped cutting blade. The cutting blade 51 is driven by the cutting drive member 52 (such as a cylinder, hydraulic cylinder, or motor screw mechanism) mounted on the frame 1 in the cutting mechanism 5 to move radially toward or away from the central axis 4 (the cutting blade 51 is mounted on the telescopic end of the cutting drive member 52). The feed direction of the cutting blade 51 is directly opposite to the axis of the central axis 4, and the feed path of the blade is aligned circumferentially with the gap between the cross rod 31. Driven by the cutting drive member 52, the cutting blade 51 feeds along a straight path, cutting each layer of steel wire in the steel wire roll layer by layer in a shearing manner. This integrated machine thus constitutes a shearing processing machine tool for cutting and segmenting waste steel wire rolls.

[0037] The all-in-one machine in this embodiment has at least a first working state and a second working state: First working state (centering state): such as Figure 2 As shown, the included angle between each rod 31 in the combined rod unit 3 and the horizontal cylinder 2 is less than 90° (preferably 30° to 60°), and the combined rod unit 3 encloses a conical working surface. After the waste steel wire roll is sleeved on the central shaft 4, the drive mechanism 6 drives the two sets of horizontal cylinders 2 to approach each other axially, and the two sets of conical working surfaces contact and clamp the end faces of the waste steel wire roll from both ends. As the horizontal cylinders 2 continue to approach, the conical working surfaces apply axial pressure and radial force to the end faces of the waste steel wire roll, gradually gathering the loose and deformed steel wires radially towards the center, while automatically aligning the axis of the steel wire roll with the axis of the horizontal cylinder 2, thus completing the centering and positioning.

[0038] During this process, the drive mechanism 6 can also drive the two sets of horizontal cylinders 2 to perform small reciprocating movements along the axial direction (amplitude of 5mm to 20mm, frequency of 0.5Hz to 3Hz), so that the combined rod units 3 on the two sets of horizontal cylinders 2 alternately apply clamping and releasing forces to the two ends of the waste steel wire roll. When clamping, the outer layer of steel wire is driven inward by the conical surface; when releasing, the inner layer of steel wire gains a small misalignment space and rearranges under the action of elastic restoring force. After multiple clamping and releasing cycles, the loose steel wire returns to its original position layer by layer from the outside to the inside, realizing the full shaping of the steel wire roll from the surface to the core.

[0039] Second working state (cage-like clamping and cutting state): as follows Figure 5 As shown, after the waste steel wire roll is gathered and centered to a predetermined degree, the angle between each rod 31 and the cross cylinder 2 is adjusted to greater than 90° (preferably 100° to 150°, at which point the tail end of the rod 31 is close to the central axis 4) by the angle adjustment mechanism 7. At this time, the rods 31 on the two sets of cross cylinders 2 flip outward. Since the two sets of rods 31 are staggered in the circumferential direction, the flipped rods 31 on the two sets of cross cylinders 2 are interlaced and inserted into each other, forming a cage-like structure that covers the outside of the waste steel wire roll.

[0040] In this cage-like structure, the gap between adjacent rods 31 extends along the axial direction of the cross cylinder 2, forming a channel for the cutting blade 51 to feed. The cutting blade 51 feeds radially and linearly along this channel, axially cutting the waste steel wire roll. During the cutting process, the cage-like structure binds the waste steel wire roll 360° from the outside, and the cut steel wire is intercepted by the rods 31 to prevent it from breaking outward.

[0041] Example 2: like Figure 1 , Figure 3 As shown, a waste steel wire roll centering and anti-collapse cage-type protective cutting integrated machine is provided. The difference between this embodiment and the first embodiment is that a knife groove 41 extending along the axial direction is provided on the outer wall of the central shaft 4.

[0042] In this embodiment, the cutting groove 41 is a strip-shaped groove formed on the outer circumferential surface of the central shaft 4, and its extension direction is parallel to the axis of the central shaft 4. The position of the cutting groove 41 on the circumferential direction of the central shaft 4 corresponds to the position of one or more gaps (i.e., channels) formed after the rods 31 on the two sets of cross cylinders 2 are inserted alternately. The width of the cutting groove 41 is greater than or equal to the thickness of the cutting blade 51, and the depth of the cutting groove 41 is greater than the feed amount of the cutting blade 51 beyond the inner hole surface of the wire coil.

[0043] The cross-sectional shape of the groove 41 can be rectangular, U-shaped or V-shaped, and in this embodiment, a rectangular groove is preferred.

[0044] In this embodiment, the cutting groove 41 is not only formed on the outer peripheral surface of the central shaft 4, but can also extend further to the end face of the cross cylinder 2. Specifically, the extension section 411 of the cutting groove 41 is provided on the working end face of the cross cylinder 2, and its circumferential position corresponds to the cutting groove 41 section on the central shaft 4. The width and depth of the extension section 411 are consistent with or smoothly transition to the cutting groove 41 section on the central shaft 4. The extension section 411 on the end face of the cross cylinder 2 is an axial groove formed on the working end face of the cross cylinder 2, forming a continuous clearance channel for the cutting blade 51 to be fed.

[0045] During the retraction, alignment, and shearing processes, the relative distance between the two sets of horizontal cylinders 2 varies depending on the width and retraction degree of the waste wire roll, and is not a fixed value. When the distance between the two sets of horizontal cylinders 2 is large, the cutting blade 51 needs to pass through the gaps in the cage-like structure's rods 31 and the radial thickness of the waste wire roll from the outside before reaching the surface of the central shaft 4. If the blade groove 41 is only located on the outer circumferential surface of the central shaft 4, the cutting blade 51 may not be able to reach the surface of the central shaft 4 at the end of the feed due to the obstruction of the end face structure of the horizontal cylinder 2, or the blade may interfere with the end face of the horizontal cylinder 2 after reaching it, resulting in the inability to completely cut the wire near the end face. By extending the blade groove 41 to the working end face of the horizontal cylinder 2, the cutting blade 51 has continuous clearance space throughout the entire feed stroke. Regardless of the axial spacing between the two sets of horizontal cylinders 2, the cutting blade 51 can smoothly enter through the extension section 411 on the end face of the horizontal cylinder 2 and further extend into the blade groove 41 section on the central shaft 4, ensuring that the cutting blade 51 can penetrate all the steel wires in the entire axial width range of the waste steel wire roll.

[0046] The feed stroke of the cutting blade 51 is set as follows: the cutting blade 51 starts to feed radially from the initial position (away from the central axis 4), passes through the gap (channel) of the corresponding rod 31 of the cage structure and the entire radial thickness of the waste steel wire roll, and finally the blade enters the blade groove 41, realizing the complete shearing of the steel wire roll.

[0047] After cutting is completed, the cutting blade 51 retracts radially to reset, the blade exits from the blade groove 41, passes through the gap between the waste steel wire roll and the cage-like structure rod 31, and returns to the initial position.

[0048] In an embodiment, such as Figure 5 As shown, the working end face of the horizontal cylinder 2 can be an inclined surface; specifically, there is an inclined angle between the working end face of the horizontal cylinder 2 and the axis of the horizontal cylinder 2, which is 5° to 30°, preferably 15°. The inclined direction of the end face is: the outer edge of the end face of the horizontal cylinder 2 is further away from the waste steel wire roll in the axial direction than the inner edge, that is, the working end face of the horizontal cylinder 2 gradually inclines towards the waste steel wire roll from the outer edge to the inner edge. The hinge seat 21 is set at the outer edge. The inclined surface makes the transition between the conical working surface and the central shaft 4 smoother.

[0049] Example 3: A cutting method for a waste steel wire coil centering and anti-collapse cage-type protective cutting integrated machine, based on Embodiment 1 and Embodiment 2, includes the following steps: Step S1. Loading: The waste steel wire coil to be processed is placed on the central shaft 4. One end (right end) of the central shaft 4 is fixedly connected to the end face of the right horizontal cylinder 2, and the other end (left end) is slidably inserted into the port of the left horizontal cylinder 2.

[0050] In practice, the two sets of horizontal cylinders 2 are first driven by the drive mechanism 6 to move in opposite directions along the axial direction, left and right, so that the left end of the central shaft 4 is pulled out from the port of the left horizontal cylinder 2. Then, the waste wire roll is placed on the central shaft 4. Finally, the drive mechanism 6 is used to drive the two sets of horizontal cylinders 2 closer together, so that the left end of the central shaft 4 is reinserted into the port of the left horizontal cylinder 2, and the waste wire roll is clamped between the two sets of horizontal cylinders 2.

[0051] Step S2. Gathering, shaping, and centering: The angle adjustment mechanism 7 adjusts the included angle between each rod 31 and the cross cylinder 2 to less than 90°, so that each rod 31 surrounds and forms a conical working surface. In this embodiment, the included angle is preferably 30° to 60°, and more preferably 45°.

[0052] The two sets of drive mechanisms 6 on both sides of the frame 1 are activated, driving the two sets of horizontal cylinders 2 to approach each other axially. The two sets of conical working surfaces (at this time, the tail ends of the rods 31 are far away from the central axis 4) contact and clamp the end faces of the waste steel wire rolls from both ends. As the horizontal cylinders 2 continue to approach, the conical working surfaces apply axial pressure and radial force to the end faces of the waste steel wire rolls, gradually gathering the loose and deformed steel wires radially towards the center, while automatically aligning the axis of the steel wire rolls with the axis of the horizontal cylinders 2, thus completing the centering and positioning.

[0053] As the two sets of horizontal cylinders 2 approach each other, the drive mechanism 6 also drives the two sets of horizontal cylinders 2 to perform small reciprocating movements along the axial direction, so that the combined rod units 3 on the two sets of horizontal cylinders 2 alternately apply clamping and releasing forces to the two ends of the waste steel wire roll. Specifically, the amplitude of the reciprocating motion is 5mm to 20mm, and the frequency is 0.5Hz to 3Hz. In the clamping stage, the conical working surface applies pressure to the end face of the steel wire roll, and the outer layer of steel wire is driven by the conical working surface to retract inward; in the releasing stage, the inner layer of steel wire obtains a small misalignment space and rearranges under the action of elastic restoring force. After multiple cycles, the loose steel wire returns to its original position layer by layer from the outside to the inside, realizing the full shaping of the steel wire roll from the surface to the core.

[0054] When the feed force of the horizontal cylinder 2 reaches the predetermined value (or the feed displacement of the horizontal cylinder 2 reaches the predetermined value), it is determined that the gathering and shaping is complete. The predetermined feed force is determined according to the specifications and materials of the waste steel wire roll, and is generally 5kN to 50kN; the predetermined feed displacement is determined according to the initial width of the waste steel wire roll and the target width after gathering.

[0055] Step S3. Cage structure is formed.

[0056] After the shaping and reshaping are completed, the following steps are used to switch and adjust the transition of the cage-like structure: First stage: The horizontal cylinder 2 remains in a fixed position, and the angle adjustment mechanism 7 drives the rod 31 to swing, causing the angle between it and the axis of the horizontal cylinder 2 to slowly rotate from 45° to 85° (close to vertical but not quite). At this time, the inner surface of the rod 31 slides smoothly along the end face of the wire coil, and the contact force gradually shifts from axial to radial. The position of the wire in the wire coil is finely adjusted as the rod 31 moves.

[0057] Second stage: The drive mechanism 6 drives the two sets of horizontal cylinders 2 to retreat slightly along the axial direction (e.g., 0.5mm to 2mm), creating a small gap between the conical working surface and the end face of the wire coil. The wire coil is released from the conical surface constraint and is in a free state. At this time, the rod 31 is basically vertical and no longer applies axial pressure to the end face of the wire coil.

[0058] Third stage: Continue to rotate the rod 31 until the angle between it and the horizontal cylinder 2 is greater than 90°, preferably more than 100°. The angle should be large enough to enclose the wire coil as needed, so that the rods 31 on both sides are inserted alternately to form a cage-like structure. At this time, the wire coil has been completely released, and the rods 31 only wrap around from the outside without generating additional compression.

[0059] Fourth stage: The drive mechanism 6 drives the two sets of horizontal cylinders 2 to move closer to each other along the axial direction again, so that the cage structure is tightly attached to the outer circumference of the wire coil, and the clamping is completed.

[0060] In this cage-like structure, the gap between adjacent rods 31 forms a channel for the cutting blade 51 to feed.

[0061] Step S4. Cutting and preventing collapse: The cutting mechanism 5 is activated, causing the cutting blade 51 to feed radially in a straight line along the gap between the rods 31, performing axial shearing on the waste steel wire coil. The feed direction of the cutting blade 51 is directly opposite to the blade groove 41 on the central shaft 4 and the extension section 411 of the blade groove 41.

[0062] The cutting blade 51 begins its radial feed from its initial position (away from the central axis 4), sequentially passing through the gaps in the cage-like structure's rods 31 and the entire radial thickness of the waste wire roll. Finally, the blade enters the blade groove 41 (including the extension section 411) and stops after reaching the predetermined depth. At this point, the cutting blade 51 has penetrated the entire radial thickness of the waste wire roll (from the outer surface to the inner surface of the inner hole), achieving complete shearing of the waste wire roll.

[0063] During the shearing process, the cage-like structure binds the waste steel wire roll from the outside 360°. The waste steel wire has already generated significant bending elastic deformation energy during winding. When cut, the constraint is released, and the elastic potential energy is released instantaneously, causing the steel wire to tend to eject and break apart outwards. However, because the cage-like structure's members 31 tightly wrap around the outside of the waste steel wire roll, the breaking force at the moment of cutting is directly intercepted by the members 31. The cut steel wire cannot eject outwards, thus eliminating safety hazards and preventing material spillage.

[0064] Step S5. Unloading: After the cutting is completed, the cutting mechanism 5 retracts radially to reset, and the cutting blade 51 exits from the blade groove 41 and returns to its initial position.

[0065] Two sets of drive mechanisms 6 drive the two sets of horizontal cylinders 2 to move away from each other axially. As the left horizontal cylinder 2 moves away from the central shaft 4, the left end of the central shaft 4 is pulled out from the port of the left horizontal cylinder 2. At the same time, as the two sets of horizontal cylinders 2 move away from each other, the included angle between each rod 31 remains unchanged or gradually decreases, and the two sets of rods 31 naturally disengage from the staggered insertion state. The sheared steel wire segment loses the restraint of the cage structure and the support of the central shaft 4, and falls freely from the central shaft 4 under the action of gravity, completing the unloading.

[0066] In this embodiment, the number of cutting mechanisms 5 can be one or more: when the waste steel wire roll needs to be cut into multiple segments, multiple cutting mechanisms 5 can be set along the circumference, and each cutting blade 51 can feed and cut along the corresponding gap at the same time, and the waste steel wire roll can be cut into multiple segments in one feed.

[0067] It should be noted that in this invention, the drive mechanism 6 (used to drive the two sets of horizontal cylinders 2 to move closer or further apart along the axial direction), the drive component 73 of the angle adjustment mechanism 7 (used to drive the angle adjustment ring 71 to slide along the axial direction of the horizontal cylinder 2), and the cutting drive component 52 of the cutting mechanism 5 (used to drive the cutting blade 51 to feed or retract radially) can all adopt conventional linear drive components in the art, such as hydraulic cylinders, pneumatic cylinders, electric push rods, or lead screw and nut mechanisms. The specific installation method, sealing structure, stroke control, and speed adjustment of the above-mentioned linear drive components are all mature technologies that can be flexibly selected by those skilled in the art according to actual load requirements. The core technical improvement of this invention does not lie in the internal structural details of a specific linear drive component, but in the mechanical coordination relationship and working state switching logic of each functional module. Therefore, the conventional structure and control method of the above-mentioned linear drive components will not be described in detail in this specification.

[0068] Furthermore, the control logic involved in this invention, such as the feed stroke control of the cross cylinder 2, the frequency and amplitude control of the reciprocating motion, the position control of the angle adjustment ring 71, and the feed speed and depth control of the cutting blade 51, can all be precisely controlled by using a programmable logic controller (PLC) or an industrial microcontroller in conjunction with displacement sensors (such as magnetostrictive displacement sensors, wire encoders, etc.). The related control algorithms and program writing are also conventional technical means in the field of automation control, and this invention does not impose any special limitations on them.

[0069] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
