Description

Technical Field

[0001] The utility model relates to the technical field of micro-cutting machines, in particular to a multi-wire cutting micro-cutting machine and a jade micro-cutting machine. Background Art

[0002] The micro-cutting machine uses the hardness and wear resistance of the cutting wire. The rotation of the wire drum drives the cutting wire to contact the object to be cut, and the object is cut by scraping. Since the cutting process will generate significant heat, coolant must be sprayed to ensure the quality of the cut object and the service life of the cutting wire.

[0003] Micro-cutting machines are widely used in the cutting and processing of hard materials such as stone, glass, and silicon wafers due to their high efficiency and precision. Micro-cutting machines are particularly effective in situations that require high precision and quality, such as jade processing. Since the shape of natural jade is usually irregular, micro-cutting machines process it into specific sizes and shapes, usually into squares, to meet the processing needs of further processing of jewelry or artworks.

[0004] The micro-cutting machine in the prior art uses a single cutting line to cut the object to be cut, and is unable to achieve simultaneous cutting of the object to be cut. This defect is particularly evident in the processing of jade products. The jade needs to be cut into small cubes first and then processed subsequently. Single-line cutting requires multiple reversing adjustments, which not only prolongs the processing time but also reduces production efficiency. Secondly, the cutting line of the existing micro-cutting machine needs to approach the object to be cut while rotating, which increases the complexity of the cutting mechanism design and the load of the cutting mechanism, which not only affects the stability of the cutting mechanism operation, but also makes maintenance and repair work complicated and difficult. Furthermore, the object to be cut is adhered to the tooling plate in advance, and the tooling plate is then fixed to the micro-cutting machine equipment by screws. This connection method requires a large amount of disassembly and assembly work, which is not only time-consuming, but also increases the workload of the operator. In addition, frequent disassembly and assembly operations may also cause wear of the screws and damage to the tooling plate, affecting the processing accuracy and the service life of the equipment. Utility Model Content

[0005] In order to improve the cutting efficiency and processing stability of a micro-cutting machine, the present application provides a multi-wire cutting micro-cutting machine and a jade micro-cutting machine.

[0006] In the first aspect, the utility model provides a multi-wire cutting micro-cutting machine adopts the following technical solution:

[0007] A multi-wire cutting micro-cutting machine includes a frame, a wire winding and unwinding mechanism, a cutting mechanism, a cutting wire, and a workbench. The wire winding and unwinding mechanism is assembled on one side of the frame and is used for winding and unwinding the cutting wire. The cutting mechanism is assembled on the other side of the frame. The cutting mechanism includes at least two sets of wire rollers, and the two sets of wire rollers are arranged at intervals. The cutting wire is wound around adjacent two sets of wire rollers. The cutting wire is wound around the wire rollers at intervals along the axial direction of the wire rollers for multiple turns to form a cutting area. The workbench is used for clamping the object to be cut and moves back and forth towards the cutting area.

[0008] Preferably, there are three sets of wire rollers, the axes of the three sets of wire rollers are parallel, and the centers of the three sets of wire rollers are arranged in a triangular shape.

[0009] Preferably, the connecting line of the centers of the two sets of wire rollers is parallel to the tabletop of the frame. The workbench is assembled on the tabletop of the frame and is located below the cutting mechanism.

[0010] Preferably, multiple sets of annular grooves are formed on the outer ring wall of the wire roller, and the multiple sets of annular grooves are arranged at equal intervals along the axial direction of the wire roller. The cutting wire is located in the annular grooves.

[0011] Preferably, the cutting mechanism includes a rotating motor. The wire roller is rotatably assembled with the frame, and the rotating end of the rotating motor is connected to the wire roller through a belt pulley and a belt for transmission.

[0012] Preferably, the cutting mechanism further includes a support member. The support member is assembled with the frame and is located on the axial side of the wire roller away from the frame. One end of the wire roller away from the frame is rotatably assembled with the support member.

[0013] Preferably, there are two sets of wire winding and unwinding mechanisms, and the two sets of wire winding and unwinding mechanisms are arranged vertically and offset. The wire winding and unwinding mechanism includes a winding and unwinding motor and a winding and unwinding cylinder. The winding and unwinding motor is assembled with the frame and is used for rotating the winding and unwinding cylinder. The cutting wire is wound around the winding and unwinding cylinder.

[0014] Preferably, it further includes a guide wheel group and a reversing wheel group. The two sets of wire winding and unwinding mechanisms are respectively an upper wire winding and unwinding mechanism and a lower wire winding and unwinding mechanism. The guide wheel group is arranged between the upper wire winding and unwinding mechanism and the cutting mechanism and is used for guiding the cutting wire. The reversing wheel group is arranged between the cutting mechanism and the lower wire winding and unwinding mechanism and is used for reversing the cutting wire.

[0015] Preferably, the workbench includes a tooling plate and a suction cup. The tooling plate is used for adhering the object to be cut. The tooling plate is magnetically connected to the suction cup. One end of the tooling plate facing downwards has a protruding pin, and the suction cup is provided with a jack for assembling with the pin.

[0016] In a second aspect, a jade micro-cutting machine provided by the present utility model adopts the following technical solution:

[0017] A jade micro-cutting machine includes the above-mentioned multi-wire cutting micro-cutting machine, and the multi-wire cutting micro-cutting machine is used for processing jade.

[0018] The beneficial effects of the present utility model are as follows:

[0019] Through the multi-wire cutting design, the cutting wires can act on the object to be cut simultaneously, improving the cutting efficiency and shortening the processing cycle. The two wire rollers are arranged at intervals, and the cutting wires are wound multiple times to form a stable cutting area, which helps to improve the cutting accuracy and ensure the processing quality. Secondly, three wire rollers arranged in a triangle make the cutting wires more evenly stressed during cutting. Compared with the arrangement of two wire rollers, the cutting wires wound on the wire rollers arranged in a triangle are more stable in tension, thus ensuring the cutting quality. Compared with the arrangement of four wire rollers in a square, the lower roller arranged in a triangle can save the winding path of the cutting wire and reduce the number of wire rollers, which can reduce the wear between the cutting wire and the wire roller to a certain extent and reduce the ineffective loss of the cutting wire.

[0020] The cutting mechanism drives the cutting wire, and the workbench drives the object to be cut to move towards the cutting wire in the cutting area, decomposing the processing actions, simplifying the driving mechanism, reducing the load of the driving mechanism, arranging the motion structures separately, reducing the failure rate, improving the stability of the equipment operation, and at the same time, reducing the difficulty of maintenance and repair.

[0021] Through the magnetic adsorption workbench, when the tooling plate is assembled with the suction cup, the plug is inserted into the jack. As the tooling plate approaches the suction cup, the tooling plate is adsorbed on the suction cup, thus completing the loading and clamping of the object to be cut. After cutting, the tooling plate is removed and a new tooling plate with the object to be cut adhered to it is loaded. By means of magnetic adsorption, the replacement efficiency is improved.

[0037] Embodiment 1: As Figure 1-9 shown, a multi-wire cutting micro-cutting machine includes a frame 1, a wire winding and unwinding mechanism 2, a cutting mechanism 3, a cutting wire 4, and a workbench 5. The wire winding and unwinding mechanism 2 is assembled on one side of the frame 1 and is used for winding and unwinding the cutting wire 4. The cutting mechanism 3 is assembled on the other side of the frame 1. The cutting mechanism 3 includes at least two sets of wire rollers, and the two sets of wire rollers are arranged at intervals. The cutting wire 4 is wound around adjacent two sets of wire rollers. The cutting wire 4 is wound around the wire rollers at intervals along the axial direction of the wire rollers for multiple turns to form a cutting area. The workbench 5 is used for clamping the object to be cut and moves back and forth towards the cutting area.

[0038] It is worth mentioning that the cutting wire 4 is wound around the wire winding and unwinding mechanism 2, the wire rollers of the cutting mechanism 3, and the wire winding and unwinding mechanism 2 in sequence to form a closed loop. Thus, when the wire winding and unwinding mechanism 2 rotates to drive the cutting wire 4 to wind and unwind, the cutting wire 4 moves back and forth on the wire rollers. When the cutting wire 4 moving back and forth contacts the object to be cut, the object to be cut is cut. Through the multi-wire cutting design, the cutting wire 4 can act on the object to be cut simultaneously, greatly improving the cutting efficiency and shortening the processing cycle. The two sets of wire rollers are arranged at intervals, and the cutting wire 4 is wound around for multiple turns to form a stable cutting area, which helps to improve the cutting accuracy and ensure the processing quality. Secondly, the cutting mechanism 3 drives the cutting wire 4, and the workbench 5 drives the object to be cut to move towards the cutting wire 4 in the cutting area, decomposing the processing actions, simplifying the driving mechanism, reducing the load of the driving mechanism, arranging the motion structures separately, reducing the failure rate, improving the stability of the equipment operation, and at the same time, reducing the difficulty of overhaul and maintenance.

[0039] In terms of the specific structural arrangement of the online rollers, there are three groups of rollers. The axes of the three groups of rollers are arranged in parallel, and the centers of the three groups of rollers are arranged in a triangle. With the three groups of rollers arranged in a triangle, when the cutting wire 4 is cutting, the force is more evenly distributed. Compared with the arrangement of two groups of rollers, the cutting wire 4 wound around the rollers arranged in a triangle has a more stable tension, thus ensuring the cutting quality. Compared with the arrangement of four groups of rollers in a square, the lower rollers arranged in a triangle can save the winding path of the cutting wire 4, and reduce the number of rollers. To a certain extent, it can reduce the wear between the cutting wire 4 and the rollers, and reduce the ineffective loss of the cutting wire 4.

[0040] In the structural arrangement of the workbench 5 and the cutting structure, the connecting line of the centers of the two groups of rollers is parallel to the tabletop of the frame 1. The workbench 5 is assembled on the tabletop of the frame 1 and is located below the cutting mechanism 3. By moving the workbench 5 up and down, the object to be cut on the workbench 5 is brought closer to the cutting wire 4, thus completing the cutting of the object to be cut.

[0041] Specifically, the three groups of rollers are the first roller 3011, the second roller 3012, and the third roller 3013 respectively. The connecting line of the centers of the first roller 3011 and the third roller 3013 is parallel to the tabletop of the frame 1. The centers of the first roller 3011 and the third roller 3013 are on the same horizontal line. The second roller 3012 is located between the third roller 3013 and the third roller 3013 and above them, thus forming a triangular arrangement.

[0042] To further improve the force stability and uniformity of the cutting wire 4, the three groups of rollers are arranged in an isosceles triangle or an equilateral triangle. To increase the effective cutting length, when the three groups of rollers are arranged in an isosceles triangle, the base length of the isosceles triangle is greater than the waist length of the isosceles triangle. The base of the isosceles triangle is the distance between the centers of the first roller 3011 and the third roller 3013. The arrangement of the isosceles triangle or the equilateral triangle makes the tension distribution of the cutting wire 4 on each roller more uniform, thus enhancing the overall force stability, reducing the vibration during the cutting process, contributing to improving the uniformity and smoothness of the cutting surface, and enhancing the processing quality. Secondly, the uniform force distribution helps to reduce the wear amount between the roller and the cutting wire 4, and reduce the maintenance cost.

[0043] To improve the stability of the cutting wire 4 wound around the roller, multiple groups of annular grooves 3014 are opened on the outer ring wall of the roller. The multiple groups of annular grooves 3014 are arranged at equal intervals along the axis of the roller. The cutting wire 4 is located in the annular grooves 3014. The design of the annular grooves 3014 enables the cutting wire 4 to be accurately positioned during winding, reduces the offset of the cutting wire 4 during the cutting process, enhances the stability of the cutting wire 4, and improves the cutting accuracy.

[0044] In order to reduce the situation where the resistance of the take-up and pay-off mechanism 2 increases when the cutting wire 4 is wound around the online roller for multiple turns, resulting in the cutting wire 4 being under tension and prone to breakage, the cutting mechanism 3 includes a rotating motor 302. The wire roller is rotationally assembled with the frame 1. The rotating end of the rotating motor 302 and the wire roller are driven by a belt pulley and a belt. Specifically, the cutting mechanism 3 includes a driving belt pulley, a driven belt pulley 304, and a synchronous belt 305. The driving belt pulley is axially connected to the rotating end of the rotating motor 302. The fixed end of the rotating motor 302 is connected to the frame 1. The driven belt pulley 304 is axially connected to one end of the wire roller close to the frame 1. Of course, each group of wire rollers is axially connected with a driven belt pulley 304. The belt is sleeved on the outer ring walls of multiple groups of driven belt pulleys 304 and the driving belt pulley, for transmitting the torque of the rotating motor 302 to drive the wire roller to rotate synchronously. Through belt drive, the torque of the rotating motor 302 can be distributed more evenly, reducing the excessive tension generated by the cutting wire 4 when wound for multiple turns and reducing the risk of the cutting wire 4 breaking. Secondly, multiple groups of wire rollers are connected by the synchronous belt 305, ensuring the synchronous rotation of all wire rollers, thus ensuring the uniform cutting of the cutting wire 4.

[0045] Among them, in order to adjust the synchronous belt 305, the frame 1 is initially provided with a vertical long slot. The fixed end of the rotating motor 302 is connected to the long slot through screws and nuts. By adjusting the vertical position of the rotating motor 302, the synchronous belt 305 can be tensioned, thereby adjusting the tension of the cutting wire 4 to make the cutting process more controllable.

[0046] In order to improve the stability of the rotation of the wire roller, the cutting mechanism 3 further includes a support member. The support member is assembled with the frame 1 and is located on the axial side of the wire roller away from the frame 1. One end of the wire roller away from the frame 1 is rotationally assembled with the support member. Specifically, the support member includes a connecting rod 3061 and a support plate 3062. One end of the connecting rod 3061 is connected to the frame 1. The axis of the connecting rod 3061 is arranged parallel to the axis of the wire roller. The support plate 3062 is arranged in a triangular shape corresponding to the layout of the three groups of wire rollers. The support plate 3062 is provided with through holes for rotational assembly with the wire roller. The support plate 3062 is detachably fixedly assembled with the connecting rod 3061 through screws. When the wire roller needs to be replaced, the support plate 3062 is removed, facilitating the replacement of the wire roller.

[0047] In terms of the specific structure of the wire winding and unwinding mechanism 2, two sets of wire winding and unwinding mechanisms 2 are provided, and the two sets of wire winding and unwinding mechanisms 2 are arranged vertically offset. The wire winding and unwinding mechanism 2 includes a wire winding and unwinding motor 201 and a wire winding and unwinding cylinder 202. The wire winding and unwinding motor 201 is assembled with the frame 1 and is used to rotate the wire winding and unwinding cylinder 202. The wire winding and unwinding cylinder 202 is wound with a cutting wire 4. Specifically, the upper set of wire winding and unwinding mechanisms 2 is the upper wire winding and unwinding mechanism 2, and the lower set of wire winding and unwinding mechanisms 2 is the lower wire winding and unwinding mechanism 2. After the cutting wire 4 passes through the cutting mechanism 3 from the upper wire winding and unwinding mechanism 2, it is wound around the lower wire winding and unwinding mechanism 2. By controlling the forward and reverse rotation of the wire winding and unwinding motor 201, the forward and reverse rotation of the wire winding and unwinding cylinder 202 is controlled, so as to perform the winding and unwinding actions on the cutting wire 4 wound around the wire winding and unwinding cylinder 202. The rotation direction of the wire winding and unwinding motor 201 of the upper wire winding and unwinding mechanism 2 is opposite to the rotation direction of the lower wire winding and unwinding mechanism 2, so that the cutting wire 4 moves back and forth on the cutting mechanism 3. It is worth mentioning that the rotation speed of the wire winding and unwinding cylinder 202 driven by the wire winding and unwinding motor 201 to drive the cutting wire 4 is matched with the rotation speed of the wire roller driven by the rotation motor 302 to drive the cutting wire 4, so that the cutting wire 4 smoothly moves back and forth between the upper wire winding and unwinding mechanism 2, the cutting mechanism 3, and the lower wire winding and unwinding mechanism 2.

[0048] Since the cutting wire 4 is wound along the axial direction of the wire roller, the cutting wire 4 enters one end of the wire roller of the cutting mechanism 3 from the upper wire winding and unwinding mechanism 2, and the cutting wire 4 returns to the lower wire winding and unwinding mechanism from the other end of the axial direction of the wire roller. In order to improve the smoothness of the movement of the cutting wire 4, this embodiment further includes a guide wheel group and a reversing wheel group. The two sets of wire winding and unwinding mechanisms 2 are respectively the upper wire winding and unwinding mechanism 2 and the lower wire winding and unwinding mechanism 2. The guide wheel group is arranged between the upper wire winding and unwinding mechanism 2 and the cutting mechanism 3 and is used to guide the cutting wire 4. The reversing wheel group is arranged between the cutting mechanism 3 and the lower wire winding and unwinding mechanism 2 and is used to reverse the cutting wire 4. The reversing wheel group is located below the guide wheel group.

[0049] Specifically, the guide wheel set includes a first guide wheel 601, an upper pressing wheel 602, and a lower tightening wheel 603. The axis of the first guide wheel 601 is parallel to the wire roller and is axially arranged. The first guide wheel 601 is rotationally assembled with the frame 1. The cutting wire 4 passes from the outer wall of the wire winding and unwinding cylinder 202 of the upper wire winding and unwinding mechanism 2, through the top wall of the first guide wheel 601, then through the top wall of the second wire roller 3012, then through the third wire roller 3013, the first wire roller 3011, and the second wire roller 3012, and is repeatedly wound along the axis of the wire roller in this way to form a cutting area for multi-wire cutting. Finally, the cutting wire 4 passes out from the bottom wall of the first wire roller 3011. The upper pressing wheel 602 is arranged between the wire winding and unwinding cylinder 202 of the upper wire winding and unwinding mechanism 2 and the first guide wheel 601. The axis of the upper pressing wheel 602 is parallel to that of the first guide wheel 601, and the upper pressing wheel 602 is located above the cutting wire 4 to tension the cutting wire 4 by gravity. The lower tightening wheel 603 is located between the first guide wheel 601 and the third wire roller 3013. The axis of the lower tightening wheel 603 is parallel to that of the first guide wheel 601, and the lower tightening wheel 603 is located below the cutting. The lower tightening wheel 603 is driven by a wire tightening motor. The rotating end of the wire tightening motor is connected to the lower tightening wheel 603 through a swing arm. By rotating the wire tightening motor, the lower tightening wheel 603 is driven to swing, thereby playing a role in tensioning the cutting wire 4.

[0050] Specifically, the commutation wheel set includes a vertical guide wheel, a second guide wheel 702, and a longitudinally arranged guide wheel 703. The vertical guide wheel 701 is arranged close to the first wire roller 3011 and is rotationally assembled with the frame 1. The axis of the vertical guide wheel 701 is vertically arranged. The second guide wheel 702 is arranged close to the wire winding and unwinding cylinder 202 of the lower wire winding and unwinding mechanism 2, and the axis of the second guide wheel 702 is parallel to the axis of the first guide wheel 601. The second guide wheel 702 is located below the second guide wheel 702. The longitudinally arranged guide wheel 703 is located below the second guide wheel 702. When the vertical orthographic projection of the commutation wheel set on the frame 1 is considered, the second guide wheel 702 and the longitudinally arranged guide wheel 703 are perpendicularly arranged, and half of the longitudinally arranged guide wheel 703 in the axial direction coincides with half of the second guide wheel 702 in the axial direction. The longitudinally arranged guide wheel 703 is located between the vertical guide wheel 701 and the second guide wheel 702. After the cutting wire 4 is wound around the wire roller for multiple turns, it passes out from the bottom wall of the first wire roller 3011, undergoes a 90° lateral commutation after passing through the vertical guide wheel 701, then passes upward through the longitudinally arranged guide wheel 703 for a 90° vertical commutation, then passes through the second guide wheel 702 for a 90° longitudinal wire change, and then winds the cutting wire 4 around the wire winding and unwinding cylinder 202 of the lower wire winding and unwinding mechanism 2.

[0051] To facilitate the loading of the object to be cut and improve the processing efficiency, the workbench 5 includes a tooling plate 501 and a suction cup 502. The tooling plate 501 is used to adhere to the object to be cut. The tooling plate 501 is magnetically connected to the suction cup 502. The lower end of the tooling plate 501 has a protruding pin. The suction cup 502 is provided with a jack for assembling with the pin. There are four groups of pins, and two groups of pins are arranged at equal angular intervals around the center of the tooling plate 501 and are located on the same diameter. When the tooling plate 501 is assembled with the suction cup 502, the pins are inserted into the jacks. As the tooling plate 501 approaches the suction cup 502, the tooling plate 501 is adsorbed on the suction cup 502, thereby completing the loading and clamping of the object to be cut. After cutting, the tooling plate 501 is removed, and a new tooling plate 501 with the object to be cut adhered to it is loaded. Through the magnetic attraction method, the replacement efficiency is improved.

[0052] Among them, the workbench 5 further includes a telescopic electric cylinder 503. The fixed seat of the telescopic electric cylinder 503 is connected to the machine base, and the telescopic end of the telescopic electric cylinder 503 is connected to the end of the suction cup 502 away from the tooling plate 501.

[0053] To improve the safety of using this micro-cutting machine, this embodiment further includes a cover 8, and the cover is assembled on the frame 1 for covering the wire winding and unwinding mechanism 2 and the cutting mechanism 3.

[0054] It is worth mentioning that the wire winding and unwinding mechanism 2 is assembled with the frame 1 through a lead screw slider to realize the reciprocating movement in the horizontal axis direction.

[0055] Embodiment 2: As Figure 1-9 shown, a jade micro-cutting machine includes the multi-wire cutting micro-cutting machine of Embodiment 1. The multi-wire cutting micro-cutting machine is used to process jade. The jade is adhered to the tooling plate 501. For cutting square jade, the multi-loop cutting wires 4 in the cutting area first cut the horizontal direction of the object to be cut to form horizontal cut marks on the object to be cut. Subsequently, the workbench 5 rotates 90°, or manually removes the tooling plate 501 from the suction cup 502, rotates 90° and then assembles the tooling plate 501 with the suction cup 502. The multi-loop cutting wires 4 in the cutting area cut the longitudinal direction of the object to be cut to form longitudinal cut marks on the object to be cut. Then, the workbench 5 moves longitudinally to cut and form jade squares, or the object to be cut is removed and then wire cutting is continued to form jade squares.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present application.
