Description

Technical Field

[0001] The present invention relates to the field of wire cutting technology, and in particular to a winding structure and method for a single-wire slicer drum. Background Art

[0002] Machine tools are used to process parts in two broad categories: plastic materials and hard and brittle materials. Machine tools for processing plastic materials are general-purpose metal cutting machines with a wide range of performance capabilities. Machine tools for processing hard and brittle parts are specialized machines (excluding EDM machines) that use diamond tools. These machines also include specialized machines for machining hard and brittle parts with diamond wire tools and slicing capabilities.

[0003] The cutting range of these slicing machines includes hard and brittle materials such as NdFeB magnetic materials, ferrite magnetic materials, ceramics, crystals, semiconductors, gemstones, quartz, glass, crystal, precious stones, and cemented carbide. Currently, diamond wire slicers are mostly used to cut these materials.

[0004] The cutting roller (also known as a roller in the industry) for multi-wire cutting has multiple winding grooves cut axially along its surface. The spacing between adjacent winding grooves is not specific, but is molded and manufactured according to the size requirements of the material being cut. Because different cutting requirements require different dimensions, winding the wire onto the cutting roller can only be done manually, which is extremely cumbersome. For a skilled worker, winding the wire once can take at least four hours. Furthermore, wire breakage is a common problem during the cutting process for various reasons. Each time the wire breaks, the diamond wire must be manually rewound onto the cutting roller, seriously affecting work efficiency.

[0005] In addition, when the multi-wire cutting machine is winding the wire onto the drum (i.e., the cutting roller), since the diamond wire on the bobbin is generally arranged in an axial spiral, the position of the wire outlet on the bobbin is constantly changing during the winding process. The bobbin needs to continuously move along with the winding position on the drum, that is, the bobbin needs to track the wire outlet position of the drum in real time. This requires the provision of multiple cooperating components such as a motor and a lead screw that can drive the bobbin to continuously move. Not only is the structure more complicated, it also leads to troublesome assembly and high cost. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a winding structure for a single-wire slicer drum with a simple and reasonable structure, easy assembly and low cost in view of the current status of the existing technology.

[0007] The second technical problem to be solved by the present invention is to provide a winding structure for a single-wire slicer drum that can quickly complete winding and improve work efficiency in response to the current status of the existing technology.

[0008] The third technical problem to be solved by the present invention is to provide a winding method for the winding structure of the above-mentioned single-wire slicer drum in response to the current status of the existing technology. This method can quickly complete the winding and improve work efficiency.

[0009] The present invention solves at least one of the above technical problems by adopting a technical solution: a winding structure of a single-wire slicer drum, comprising a frame, a drum and a bobbin, wherein the drum is rotatably arranged on the frame, and the bobbin is rotatably arranged on one side of the drum, characterized in that: it also includes

[0010] a guide wheel assembly, provided on the frame and located in front of the drum, comprising a first positioning guide wheel capable of positioning the outlet position of the drum, a second positioning guide wheel capable of positioning the return position of the drum, and a plurality of wheels for guiding the cutting line between the first positioning guide wheel and the second positioning guide wheel to form a cutting area; the lower edge of the first positioning guide wheel is aligned with the upper edge of the drum, and the lower edge of the second positioning guide wheel is aligned with the lower edge of the drum; and

[0011] A floating guide wheel is rotatably and reciprocatingly mounted on the frame, the floating guide wheel being located at the rear of the drum and having its swing axis perpendicular to the drum axis;

[0012] The roller is arranged on the frame so as to be reciprocatingly movable along its axial direction. The bobbin is arranged below the guide wheel and its axial direction is in the same direction as that of the roller and the floating guide wheel.

[0013] The winding structure of the above-mentioned single-wire slicer drum also includes a bracket and a swinging body, the bracket is arranged on the frame; the swinging body is arranged on the bracket so as to be able to swing back and forth, and the swinging axis of the swinging body is perpendicular to the axial direction of the drum; the floating guide wheel is rotatably arranged on the swinging body and swings synchronously with the swinging body, and the rotation axis of the guide wheel is parallel to the axial direction of the drum in a static state.

[0014] As an improvement, the winding structure of the single-wire slicer drum further includes a support arm assembly, the upper portion of which is adjustable up and down and arranged on the swinging body, the lower portion of which extends toward the drum, and the guide wheel rotatably arranged on the lower portion of the support arm assembly. The guide wheel is generally made of plastic material. After a period of use, the friction of the cutting line can easily cause the wire groove on the guide wheel to deepen, resulting in the position of the cutting line being unable to be located in the same horizontal plane as the swinging centerline of the swinging body and the upper edge of the drum, affecting the winding accuracy. With the above structure, the support arm assembly is movably arranged on the bracket up and down. After the depth of the guide groove on the guide wheel changes, the height of the guide wheel can be adjusted in real time, so that the position of the cutting line is always located in the same horizontal plane as the swinging centerline of the swinging body and the upper edge of the drum, thereby maintaining the winding accuracy.

[0015] To facilitate assembly, the support arm assembly includes a connecting arm and a top plate. The connecting arm is formed into an L shape. The vertical part of the L-shaped connecting arm is constrained on the swing body. The horizontal part of the L-shaped connecting arm extends toward the roller and is used to install the guide wheel. The top plate can be adjusted up and down and is arranged above the swing body and the side is connected to the connecting arm.

[0016] In order to facilitate the upward and downward adjustment of the position of the guide wheel, an adjustment component capable of lifting the top plate up and down is connected between the top plate and the swing body, and the adjustment component is threadedly connected between the top plate and the swing body.

[0017] Preferably, the adjustment assembly includes an elastic member and an adjustment screw. The elastic member is positioned between the top of the oscillating body and the top plate, ensuring that the top plate maintains an upward movement. The top plate has a through-hole extending vertically therethrough. Correspondingly, a threaded hole is formed in the top wall of the oscillating body. The adjustment screw passes through the through-hole and its lower end is threadedly engaged in the threaded hole. The upper portion of the adjustment screw has a circumferentially arranged retaining ring that abuts against the upper wall of the top plate. Turning the adjustment screw allows for fine-tuning of the guide wheel's vertical position to meet the required guide wheel height, and is convenient to operate.

[0018] The elastic member comprises a spring and a push rod. A slot for accommodating the spring is defined in the top wall of the swinging body. The spring is positioned within the slot, with its lower end abutting the inner bottom wall of the slot. The push rod's lower end is connected to the spring's upper end and concealed within the slot. The push rod's upper end abuts the lower wall of the top plate, thereby maintaining a tendency for the top plate to move upward relative to the swinging body. The elastic members are arranged in at least two groups, preferably four groups, surrounding the periphery of the adjustment screw.

[0019] Preferably, the adjustment assembly further includes a set screw extending vertically through the adjustment screw. The set screw passes through the adjustment screw and its lower end is connected to the bottom wall of the threaded hole. The upper end of the set screw is exposed above the adjustment screw and includes a stopper that abuts against the top wall of the adjustment screw to limit upward movement of the adjustment screw. The set screw is longer than the adjustment screw. When assembled, the set screw defines an adjustment range located above the adjustment screw and allowing for upward adjustment of the adjustment screw. This set screw prevents the top plate from detaching from the swinging body due to over-adjustment of the adjustment screw, thereby improving assembly stability.

[0020] To facilitate assembly, two connecting arms are arranged parallel to each other on either side of the swinging body. The connecting arms are fastened to the sidewalls of the swinging body via screws. The guide wheel is rotatably connected between the lower ends of the two connecting arms. The guide wheel is rotatably connected between the two connecting arms via a guide wheel shaft and corresponding bearings. This rotatable connection structure is a conventional rotating wheel mounting structure and will not be described in detail here.

[0021] In each of the above solutions, the bracket is provided with a rotating shaft extending forward and backward, and the rear wall of the swinging body is provided with a shaft hole extending forward and into which the front portion of the rotating shaft is inserted. The inner wall of the shaft hole and the rotating shaft are rotatably engaged via a bearing, and a cover is further provided on the rear side of the shaft hole to seal the bearing in the shaft hole. The above structure is used to achieve reciprocating swinging of the swinging body.

[0022] Preferably, the wire spool is mounted on the machine frame so that it can move back and forth via an assembly rack. The assembly rack has a horizontally arranged support plate on its upper portion. The bracket is mounted on this support plate and extends vertically through its lower portion. The support plate and the bracket have openings in the upper portion corresponding to the guide wheel for the cutting wire to pass through, and the openings are elongated holes. This structure can guide the cutting wire and prevent it from being tangled.

[0023] The bobbin comprises a pay-off and take-up spool arranged side by side, each of which is capable of reciprocating along the axial direction of the drum. The frame is further provided with a first drive member for driving the drum to rotate, a second drive member for driving the drum to reciprocate along the axial direction, and a third drive member for driving the bobbin to rotate along the axial direction. The drum is mounted on the frame for axial reciprocal movement via a screw rod and a nut pair.

[0024] The frame of the present invention is further provided with a fourth drive member capable of driving the roller to reciprocate perpendicularly to its axial direction. The roller is mounted on the frame for reciprocal movement perpendicularly to its axial direction via a screw and nut assembly. The fourth drive member and corresponding movement structure allow the tension of the cutting line to be varied by moving the roller perpendicularly to its axial direction after winding is completed, thereby pre-setting tension on the cutting line.

[0025] A winding method for the winding structure of the single-wire slicer drum is characterized by:

[0026] When winding the wire onto the drum: align the middle of the pay-off drum with the floating guide wheel, and the cutting wire extending from the pay-off drum passes around the top edge of the floating guide wheel, and then passes around the first positioning guide wheel, the other wheels of the guide wheel assembly, and the second positioning guide wheel in sequence, and is fixed on the drum near the first end; the drum is moved axially while rotating, and the cutting wire is wound from the first end to the second end of the drum. During this process, the floating guide wheel continuously swings, and its swing center line is kept in the same horizontal plane as the upper edge of the drum, so as to keep the cutting wire wound onto the drum from being backed off, until the amount of wire stored on the drum meets the requirements, and the cutting wire on the pay-off drum is cut and fixed on the drum near the second end;

[0027] When recycling the waste wire on the drum: the cut wire near the second end of the drum is fixed on the take-up drum, and then the take-up drum is rotated. At the same time, the drum moves back and forth along the axial direction, and the cut wire on the drum is continuously wound along the axial direction of the take-up drum until the recycling is completed.

[0028] Compared with the prior art, the advantages of the present invention are: the present invention has a simple and reasonable structure, is easy to assemble, and has low cost. By adopting the structure and method of the present invention to wind the wire onto the drum or to recycle the waste wire on the drum, the winding can be automatically completed by the rotation and movement of the drum in coordination with the rotation of the bobbin, without the need for manual winding. The winding can be completed quickly in 1-2 hours, which greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0038] In the present invention, directional words such as "up", "down", "left", "right" and "side" are used, but these directional words only indicate relative position relationships and are not limited to absolute directions. For example, "up" and "down" are not limited to directions opposite to or consistent with the direction of gravity.

[0039] The structure of this embodiment is mainly used in cutting wire slicers in the field of single-wire cutting.

[0040] like Figures 1 to 8As shown, the winding structure of the single-wire slicing machine drum in this embodiment includes a frame 1, a drum 2, a bobbin 3, a bracket 4, an oscillating member 5, a floating guide wheel 6, and a guide wheel assembly a. The drum 2 is rotatably mounted on the frame 1 and arranged horizontally. The bobbin 3 is rotatably mounted on the rear side wall of the frame 1 and positioned below the drum 2. The guide wheel assembly a is mounted on the frame 1 and positioned in front of the drum 2. The guide wheel assembly a includes a first positioning guide wheel 1a for positioning the wire outlet position on the drum 2, a second positioning guide wheel 2a for positioning the wire return position on the drum 2, and a plurality of wheels for guiding the cutting wire 10 between the first positioning guide wheel 1a and the second positioning guide wheel 2a to form a cutting area 3a. The lower edge of the first positioning guide wheel 1a is aligned with the upper edge of the drum 2, and the lower edge of the second positioning guide wheel 2a is aligned with the lower edge of the drum 2. The bracket 4 is mounted on the rear side of the frame 1 and positioned above the bobbin 3. The upper end of the bracket 4 is positioned higher than the drum 2. The swinging member 5 is mounted on the front side of the bracket 4, capable of reciprocating perpendicular to the axis of the drum 2. The bracket 4 is provided with a rotating shaft 41 extending forward and backward. The rear wall of the swinging member 5 defines a shaft hole 50 extending forward and receiving the front portion of the rotating shaft. The inner wall of the shaft hole 50 is rotatably engaged with the rotating shaft 41 via a bearing 100. A cover 501 is also provided on the rear side of the shaft hole 50, which seals the bearing 100 within the shaft hole 50, enabling the reciprocating oscillation of the swinging member 5. A floating guide wheel 6 is rotatably mounted on the swinging member 5 and oscillates synchronously with the swinging member 5. The axis of the floating guide wheel 6 is parallel to the axis of the drum 2.

[0041] In this embodiment, the floating guide wheel 6 is mounted on the swinging body 5 via a support arm assembly 7. The upper portion of the support arm assembly 7 is vertically adjustable on the swinging body 5, while the lower portion of the support arm assembly 7 extends toward the drum 2. The floating guide wheel 6 is rotatably mounted on the lower portion of the support arm assembly 7. The floating guide wheel 6 is generally made of a plastic material. After a period of use, friction from the cutting line 10 can easily cause the wire groove 61 in the floating guide wheel 6 to deepen, causing the cutting line 10 to lose alignment with the swing centerline of the swinging body 5, affecting winding accuracy. With the above-described structure, the support arm assembly 7 is vertically movably mounted on the bracket 4. As the depth of the guide groove 61 in the floating guide wheel 6 changes, the height of the floating guide wheel 6 can be adjusted in real time, thereby ensuring that the cutting line 10 is always aligned with the swing centerline of the swinging body 5 and maintaining winding accuracy.

[0042] like Figure 4 、 5As shown, the support arm assembly 7 comprises a connecting arm 71 and a top plate 72. The connecting arm 71 is L-shaped. The vertical portion 711 of the L-shaped connecting arm 71 is constrained to the swinging body 5. The transverse portion 712 of the L-shaped connecting arm 71 extends toward the drum 2 and is used to mount the floating guide wheel 6. The top plate 72 is vertically adjustable above the swinging body 5 and is connected to the side of the connecting arm 71. An adjustment assembly 8 is connected between the top plate 72 and the swinging body 5 to enable the top plate 72 to be raised and lowered. The adjustment assembly 8 is threadedly connected between the top plate 72 and the swinging body 5. Two connecting arms 71 are arranged parallel to each other on either side of the swinging body 5. The connecting arms 71 are fastened to the side walls of the swinging body 5 via screws 200. The floating guide wheel 6 is rotatably connected between the lower ends of the two connecting arms 71. The floating guide wheel 6 is rotatably connected between the two connecting arms 71 via a guide wheel shaft and corresponding bearings. This rotatable connection structure is similar to a conventional rotating wheel mounting structure and will not be described in detail here. The cutting line 10 at the top edge of the floating guide wheel 6, the swing center line of the swing body 5 and the upper edge of the drum 2 are located in the same plane.

[0043] Specifically, such as Figure 5 As shown, the adjustment assembly 8 includes an elastic member 81, an adjustment screw 82, and a positioning screw 83. The elastic member 81 is disposed between the top of the swinging body 5 and the top plate 72, and maintains the upward movement of the top plate 72. The top plate 72 has a through hole 721 extending vertically therethrough. Correspondingly, a threaded hole 51 is formed on the top wall of the swinging body 5. The adjustment screw 82 passes through the through hole 721 and its lower end is threadedly connected to the threaded hole 51. The upper portion of the adjustment screw 82 has a circumferentially arranged retaining ring 821 that abuts against the upper wall of the top plate 72. Turning the adjustment screw 82 allows for fine-tuning of the vertical position of the floating guide wheel 6 to meet the required height of the floating guide wheel 6, and is easy to operate. The elastic member 81 comprises a spring 811 and a push rod 812. A slot 52 for accommodating the spring 811 is defined on the top wall of the swinging member 5. The spring 811 is positioned within the slot 52, with its lower end abutting against the inner bottom wall of the slot 52. The push rod 812, with its lower end connected to the upper end of the spring 811, is concealed within the slot 52. The upper end of the push rod 812 abuts against the lower wall of the top plate 72, thereby maintaining an upward movement of the top plate 72 relative to the swinging member 5. Four sets of elastic members 81 are arranged around the periphery of the adjusting screw 82. The adjusting screw 82 extends vertically through the adjusting screw 82. A positioning screw 83 passes through the adjusting screw 82 and its lower end is threadedly connected to the bottom wall of the threaded hole 51. The upper end of the positioning screw 83 protrudes above the adjusting screw 82 and includes a stopper 831 that abuts against the top wall of the adjusting screw 82, thereby limiting its upward movement. The length of the positioning screw 83 is greater than that of the adjusting screw 82. When assembled, the positioning screw 83 has an adjustment range 832 located above the adjusting screw 82 and allowing the adjusting screw 82 to move upward. The positioning screw 83 prevents the top plate 72 from separating from the swinging body 5 when the adjusting screw 82 is over-adjusted, thereby improving assembly stability.

[0044] like Figure 2 As shown, the bobbin 3 of this embodiment is mounted on the rear side wall of the frame 1 so that it can move back and forth axially along the drum 2. The frame 1 is also provided with a third drive member 20, which is a motor, capable of driving the bobbin 3 to rotate in a set direction when the cutting line is being recovered. After a period of use, the performance of the cutting line 10 deteriorates and requires regular replacement. The above structure facilitates the recovery of waste line. The bobbin 3 is mounted on the frame 1 so that it can move back and forth via an assembly rack 9. The assembly rack 9 is connected to the frame 1 at the front and rear ends by transversely arranged guide rails 91. The upper portion of the assembly rack 9 has a horizontally arranged support plate 92. The bracket 4 is mounted on this support plate 92 and extends vertically through the lower portion. The support plate 92 and the upper portion of the bracket 4 have openings 921 and 923 for the cutting line 10 to pass through, corresponding to the floating guide wheel 6. This structure guides the cutting line 10 and prevents it from becoming disorganized.

[0045] In this embodiment, the motor 20 at the end of the bobbin 3 applies a pull-back force to the cutting line on the bobbin 3 when the line is being fed onto the drum 2. When the line is being unthreaded, the motor at the end of the drum 2 applies a pull-back force to the cutting line on the drum 2. The two bobbins 3 are used for thread feeding and unthreading, respectively.

[0046] When the cutting wire 10 on the bobbin 3 is wound onto the drum 2 using the winding structure of this embodiment, the bobbin 3 rolls, and the drum 2 rotates and continuously moves in the axial direction. Figure 6 As shown, after the cutting line 10 on the bobbin 3 passes through the floating guide wheel 6, the floating guide wheel 6 swings back and forth perpendicular to the axial direction of the drum 2 under the traction of the direction-changing force of the cutting line 10, thereby balancing the tension change of the cutting line 10 caused by the different outlet positions on the bobbin 3. Since the cutting line 10 at the top edge of the floating guide wheel 6 is always colinear with the swing center line of the swing body 5 during the swinging process, it can ensure that the position of the cutting line 10 after passing the floating guide wheel 6 is constant, so that the bobbin 3 can track the outlet position of the drum 2 in real time while remaining axially stationary.

[0047] The wire spool 3 of this embodiment may include a pay-off spool 31 and a take-up spool 32 arranged side by side, each of which can move back and forth along the axial direction of the drum 2. The frame 1 is also provided with a first drive member 1b for driving the drum 2 to rotate, a second drive member 2b for driving the drum 2 to reciprocate along the axial direction, and a third drive member 20 for driving the wire spool 3 to rotate along its axial direction. The drum 2 is mounted on the frame 1 so as to be reciprocable along the axial direction via the matching structure of a screw rod and a nut pair. The frame 1 is also provided with a fourth drive member 4b that can drive the drum 2 to reciprocate in a direction perpendicular to its axial direction. The drum 2 is mounted on the frame 1 so as to be reciprocable in a direction perpendicular to its axial direction via the matching structure of a screw rod and a nut pair. The fourth drive member 4b and the corresponding moving structure are provided so that the tightness of the cutting line can be changed by moving the drum 2 perpendicular to its axial direction after winding is completed, thereby pre-setting tension on the cutting line.

[0048] In this embodiment, the axial directions of the first and second positioning guide wheels 1a, 2a are aligned with the axial direction of the drum 2. A differential axial displacement exists between the first and second positioning guide wheels 1a, 2a, thereby maintaining a constant spacing c between the outgoing and return wires on the drum 2. This spacing c is preferably 5-10 mm. With this structure, although the outgoing and return wires continuously reciprocate axially on the drum during operation, this spacing prevents crossover and breakage of the outgoing and return wires, which could result from wire breakage.

[0049] The winding method of the winding structure of the single-wire slicer drum in this embodiment is as follows:

[0050] When winding the wire onto the drum: Figure 2As shown, the middle part of the pay-off drum 31 is aligned with the floating guide wheel 6, and the cutting line 10 extending from the pay-off drum 31 passes around the top edge of the floating guide wheel 6, and then passes around the first positioning guide wheel 1a, the other wheels of the guide wheel assembly a, and the second positioning guide wheel 2a in sequence, and is fixed on the drum 2 near the first end (right end); the drum 2 is made to reciprocate along the axial direction while rotating, and the main body of the drum 2 moves in the direction indicated by the arrow, and the cutting line 10 is wound from the first end (right end) of the drum 2 to the second end (left end). In this process, since the diameters of the pay-off drum 31 and the drum 2 are different and the diameter of the pay-off drum 31 is continuously reduced, the drum 2 moves axially each time. The distance and the rotation speed of the drum 2 are variables. It is sufficient to ensure that the length of the cutting line wound on the drum 2 and the cutting line discharged from the pay-off reel 31 are consistent in each rotation cycle of the drum 2; the floating guide wheel 6 continuously swings, keeping its swing center line and the upper edge of the drum 2 in the same horizontal plane, so as to keep the cutting line wound on the drum 2 from being backed up, until the amount of line stored on the drum 2 meets the requirements, the cutting line 10 on the pay-off reel 31 is cut and fixed on the drum 2 near the second end (left end); after the winding is completed, the drum 2 is moved forward in a direction perpendicular to its axial direction, tightening the cutting line to preset tension on the cutting line, and the data of the preset tension can be read by a sensor linked to the cutting line;

[0051] When recycling the waste wire on the drum: Figure 8 As shown, the cutting line 1 near the second end (left end) of the drum 2 is fixed on the wire take-up reel 32, and then the wire take-up reel 32 is rotated. At the same time, the drum 2 moves back and forth in the axial direction, and the main body of the drum 2 moves in the direction indicated by the arrow. In this process, since the diameters of the wire take-up reel 32 and the drum 2 are different and the diameter of the wire take-up reel 32 is constantly increasing, the distance of each axial movement of the drum 2 and the speed of the drum 2 are variables. It is sufficient to ensure that the cutting line discharged by the drum 2 is consistent with the length of the cutting line wound on the wire take-up reel 32 after each rotation of the drum 2 until the recovery is completed.

[0052] In the above winding and waste wire recycling process, only the right end is used as the first end and the left end is used as the second end for explanation, but it should be pointed out that the right end can also be used as the second end and the left end as the first end. The principle and method of use are the same as the above process and will not be repeated here.

[0053] The cutting wire in this embodiment is a diamond wire, but the structure of the present invention itself is not restricted by the cutting wire. As long as the wire harness with cutting capability adopts the structure of this embodiment, the cutting function described in the present invention can be realized in principle.
