Description

Technical Field

[0001] The utility model belongs to the technical field of cutting and relates to a single-wire cutting device. Background Art

[0002] Wire cutting is a cutting technique that uses a high-speed cutting wire to contact the workpiece for grinding. It is widely used in the processing of hard and brittle materials. A metal cutting wire, typically a diamond wire, is used as the cutting tool. The cutting wire is a flexible tool, and during the actual processing process, a bow is generated when the cutting wire contacts the workpiece. Large bows require the cutting wire to overcome a larger bend radius and curved path during bending, resulting in a corresponding reduction in cutting speed. Furthermore, the cutting wire is subject to greater stress and deformation during bending, potentially increasing bending distortion and affecting the geometry and dimensional accuracy of the cut part. In order to solve the above problems, multiple tension guide wheels are usually set when the cutting line is laid out, such as a single-wire cutting device published with application number 201520663445.8, wherein the wire control mechanism includes a motor, an I-line wheel, a first guide wheel, a second guide wheel, a third guide wheel, and a fourth guide wheel. The I-line wheel is fixedly installed with the motor, the first guide wheel, the second guide wheel, and the third guide wheel are distributed in a triangle, the first guide wheel, the second guide wheel and the frame are installed with a rotating shaft, the fourth guide wheel and the first guide wheel are arranged on the same horizontal plane, and an indented space is provided on the cutting frame, and a left cutting wheel and a right cutting wheel are respectively provided on both sides of the indented space. The first guide wheel, the second guide wheel and the third guide wheel in the above scheme form a winding and are close to the cutting end, so that the cutting line close to the cutting end has a larger tension force, while the fourth guide wheel is not set to form a winding with the I-line wheel for winding the cutting line, so that the tension force of the cutting line near the cutting end is weak. During high-speed cutting, the cutting line close to one end of the I-line wheel is easy to relax, affecting the routing of the cutting line, and the cutting effect cannot be guaranteed. Utility Model Content

[0003] The purpose of this utility model is to solve the above problems in the existing technology and propose a single-wire cutting device. The technical problem to be solved by this utility model is: how to simplify the wiring layout while ensuring the cutting effect.

[0004] In order to achieve the above purpose, the present invention is implemented through the following technical solutions:

[0005] A single-wire cutting device comprises a frame, a loading platform is horizontally arranged on the frame, a first guide group and a second guide group are provided on the frame, the first guide group and the second guide group are respectively located on both sides of the upper part of the loading platform, and is characterized in that the frame is also provided with two vertically arranged wire drums that can rotate in the same direction and two cutting guide wheels that can move along the vertical direction, the two wire drums and the two cutting guide wheels are arranged on the left and right sides of the loading platform, the two wire drums are respectively adjacent to each other with horizontally arranged transition wheels, and the two transition wheels are adjacent to each other with steering wheels, and the central axis of the steering wheel is parallel to the central axis of the cutting guide wheel.

[0006] The cutting wire winding drum, transition wheel, steering wheel, first guide group, second guide group, steering wheel on the other side, transition wheel and wire drum. The wire drum can be driven by a driving device such as a motor. The two wire drums rotate back and forth in the same direction to realize the reciprocating motion of the cutting wire. The two cutting guide wheels are driven by a driving mechanism such as a motor to make the two cutting guide wheels move vertically. When the cutting operation is performed, the cutting wire reciprocates under the reciprocating motion of the two wire drums. Under the action of the two cutting guide wheels, the cutting wire located between the two cutting guide wheels contacts the workpiece to be processed and cuts the workpiece to be processed. The first guide group and the second guide group respectively form a winding close to the cutting end of the cutting line, and the transition wheel and the steering wheel arranged near the wire drum for winding the cutting line form a winding away from the cutting end of the cutting line, so that the cutting line has a large tensioning force at both the winding end and the cutting end, so that the cutting line is kept in a tensioned state to ensure the cutting effect. The vertically arranged wire drum can hide the driving mechanism connected to the wire drum inside the equipment, increase the space utilization rate of the equipment, and improve the compactness of the device. In addition, in the prior art, the horizontally arranged wire drum will cause the cutting line to be offset due to the tension when the cutting line is wound, resulting in a deviation in the tension force. The vertically arranged wire drum has less effect on the position of the cutting line under tension, thereby ensuring the position and direction of the cutting line on the wire drum, reducing the problem of tension deviation caused by the offset of the cutting line, and ensuring the cutting effect.

[0007] In the above-mentioned single-wire cutting device, the first guide group includes a tension adjustment wheel and two first tension guide wheels. The tension adjustment wheel and one of the first tension guide wheels are spaced apart and located above the other first tension guide wheel, and the lower first tension guide wheel is located directly above the steering wheel on the same side. The arrangement of the tension adjustment wheels enables flexible adjustment of the wire tension and effectively controls the tightness of the cutting wire to adapt to different working requirements and material properties. One of the first tension guide wheels is adjacent to the tension adjustment wheel, which helps to disperse the tension and reduce the concentration of wire tension, thereby reducing the generation of wire bow. The other first tension guide wheel is located directly above the first steering wheel, which helps to maintain the proper position of the wire and reduce the possibility of wire deviation. This solution, through reasonable layout and arrangement, compactly combines the tension adjustment wheel and the first tension guide wheel to form a simple guide group, which not only helps to reduce the size and weight of the equipment, but also improves production efficiency and operational convenience. It takes into account the adjustment of wire tension while ensuring good guiding performance, provides a more stable and controllable environment, and improves the accuracy and efficiency of cutting or processing.

[0008] In the aforementioned single-wire cutting device, the second guide group includes only one second tension guide wheel, located above the diverter wheel on the same side. The second tension guide wheel further enhances the wire guiding effect, helps distribute wire tension, and effectively reduces wire tension concentration while maintaining appropriate tension, further reducing the risk of wire bowing.

[0009] In the above-mentioned single-wire cutting device, two supports are provided on the frame, and the two steering wheels and the corresponding transition wheels are rotatably connected to the two supports. The provision of the supports improves the convenience of installing the steering wheels and the transition wheels.

[0010] In the above-mentioned single-wire cutting device, the frame has a first connecting column arranged in a one-to-one correspondence with the first tension guide wheel, and a plurality of the first connecting columns are arranged along the front-to-back direction of the worktable. The two first tension guide wheels are rotatably connected to the ends of the corresponding first connecting columns. The frame is also rotatably connected to an adjustment arm, and the tension adjustment wheel is rotatably connected to the adjustment arm. The end faces of the tension adjustment wheel, the two first tension guide wheels, and the steering wheel on the same side are coplanar. Through the setting of the first connecting column, the connection between the first tension guide wheel and the frame is more secure. Through the rotation connection of the adjustment arm, the tension adjustment wheel can be flexibly adjusted, and the position and angle of the tension adjustment wheel can be easily changed to meet different working requirements and material properties, thereby enhancing the adaptability of the device and the processing accuracy. The coplanarity of the end faces of the tension adjustment wheel, the two first tension guide wheels, and the steering wheel on the same side helps to ensure the smooth routing of the cutting line and avoid deviation or distortion of the line.

[0011] In the aforementioned single-wire cutting device, the frame includes a second connecting post corresponding to the second tension guide wheel. The second tension guide wheel is rotatably connected to the end of the second connecting post. The second tension guide wheel is coplanar with the end surface of the steering wheel on the same side. The coplanarity of the end surfaces of the second tension guide wheel and the steering wheel on the same side ensures smooth transfer of the cutting wire between the steering wheel and the tension guide wheel, and reduces the possibility of wire deviation and twisting.

[0012] In the aforementioned single-wire cutting device, two vertically movable guide blocks are mounted on the frame. The guide blocks move vertically in opposite directions, and the two cutting guide wheels are connected to the guide blocks. The two guide blocks move in opposite directions, causing the two cutting guide wheels to move in opposite directions, resulting in an oscillating cutting motion. This achieves point-contact cutting of the workpiece, reduces cutting load, and ensures cutting accuracy.

[0013] In the aforementioned single-wire cutting device, the end faces of the two cutting guide wheels are coplanar with the end faces of the first and second tension guide wheels. This ensures smooth guidance of the wire throughout the cutting device, reduces the likelihood of wire deviation and twisting, and ensures wire stability and accuracy during cutting. This also allows for more evenly distributed wire tension as the cutting wire is routed, avoiding cutting problems caused by uneven tension.

[0014] In the aforementioned single-wire cutting device, the frame is provided with a long, rectangular base plate, and the worktable is slidably mounted on the base plate in a forward and backward direction. The sliding of the worktable on the base plate enables the movement of the workpiece to be processed, enabling automatic and continuous cutting of the workpiece, thereby improving cutting efficiency.

[0015] In the above-mentioned single-wire cutting device, the central axis of the cutting guide wheel is parallel to the moving direction of the worktable. The parallelism between the cutting guide wheel and the moving direction of the worktable ensures the consistency of the cutting line direction and the cutting effect of the workpiece to be processed.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The first guide group and the second guide group respectively form a winding close to the cutting end of the cutting wire, and the transition wheel and the steering wheel arranged near the wire drum of the winding cutting wire form a winding away from the cutting end of the cutting wire, so that the cutting wire has a large tension force at both the winding end and the cutting end, so that the cutting wire remains in a tensioned state and ensures the cutting effect.

[0018] 2. In the prior art, when the wire drum is horizontally arranged, the cutting wire will be offset due to the tension during the winding operation, resulting in a deviation in the tension force. However, the wire drum arranged vertically has less influence on the position of the cutting wire under tension, thereby ensuring the position and direction of the cutting wire on the wire drum, reducing the problem of tension deviation caused by the deviation of the cutting wire, and ensuring the cutting effect.

The frame 1 is also provided with two vertically arranged wire drums 4 that can rotate in the same direction and two cutting guide wheels 8 that can move in the vertical direction. The two wire drums 4 and the two cutting guide wheels 8 are arranged on the left and right sides of the worktable 2. The two wire drums 4 are respectively adjacent to each other with horizontally arranged transition wheels 5. The two transition wheels 5 are adjacent to each other with steering wheels 104. The central axis of the steering wheel 104 is parallel to the central axis of the cutting guide wheel 8. The first tension guide wheel 62 located below is located directly above the steering wheel 104 on the same side, and the second tension guide wheel 7 is located above the steering wheel 104 on the same side.

[0023] The arrangement of the tension adjustment wheel 61 enables the tension of the wire to be flexibly adjusted, effectively controlling the tightness of the cutting wire to adapt to different working requirements and material properties. One of the first tension guide wheels 62 is adjacent to the tension adjustment wheel 61, which can help disperse the tension, reduce the concentration of tension in the wire, and thus reduce the occurrence of wire bows. The other first tension guide wheel 62 is located directly above the first steering wheel 104, which helps maintain the proper position of the wire and reduces the possibility of wire deviation. This solution, through reasonable layout and arrangement, compactly combines the tension adjustment wheel 61 and the first tension guide wheel 62 to form a simple guide group. This structural simplicity not only helps to reduce the volume and weight of the equipment, but also improves production efficiency and operational convenience. It takes into account the tension adjustment of the wire and ensures good guiding performance, providing a more stable and controllable environment, and improving the accuracy and efficiency of cutting or processing. The arrangement of the second tension guide wheel 7 further enhances the guiding effect of the wire, helps to disperse the tension of the wire, effectively reduces the concentration of tension in the wire while maintaining appropriate tension, and further reduces the risk of wire bows.

[0024] The frame 1 has a first connecting column 101 which is arranged in a one-to-one correspondence with the first tension guide wheel 62, and several first connecting columns 101 are arranged along the front and rear directions of the worktable 2, and the two first tension guide wheels 62 are rotatably connected to the ends of the corresponding first connecting column 101. The frame 1 has two supports 105, and the two steering wheels 104 and the corresponding transition wheels 5 are rotatably connected to the two supports 105 respectively. The frame 1 is also rotatably connected to an adjusting arm 102, and the tension adjusting wheel 61 is rotatably connected to the adjusting arm 102. The tension adjusting wheel 61 and the two first tension guide wheels 62 are coplanar with the end face of the steering wheel 104 on the same side. The frame 1 has a second connecting column 103 which is arranged corresponding to the second tension guide wheel 7, and the second tension guide wheel 7 is rotatably connected to the end face of the second connecting column 103.

Through the rotational connection of the adjustment arm 102, the tension adjustment wheel 61 can be flexibly adjusted, and the position and angle of the tension adjustment wheel 61 can be conveniently changed to meet different working requirements and material properties, thereby enhancing the adaptability of the device and the accuracy of processing. The coplanarity of the end faces of the tension adjustment wheel 61, the two first tension guide wheels 62, and the steering wheel 104 on the same side helps ensure the smooth routing of the cutting line and avoids deviation or distortion of the line. The coplanarity of the end faces of the second tension guide wheel 7 and the steering wheel 104 on the same side ensures the smooth transmission of the cutting line between the steering wheel 104 and the tension guide wheel, and reduces the possibility of deviation and distortion of the line.

[0025] Two vertically movable guide blocks 9 are mounted on the frame 1. The guide blocks 9 move vertically in opposite directions, and the two cutting guide wheels 8 are connected to the two guide blocks 9. The two guide blocks 9 move in opposite directions, causing the two cutting guide wheels 8 to move in opposite directions, forming an oscillating cutting method, achieving point-contact cutting of the workpiece to be processed, reducing the cutting load and ensuring cutting accuracy.

[0026] The end faces of the two cutting guide wheels 8 are coplanar with the end faces of the first tension guide wheel 62 and the second tension guide wheel 7. By making the end faces of the two cutting guide wheels 8 coplanar with the end faces of the tension guide wheels, the smooth guidance of the wire in the entire cutting device is ensured, the possibility of wire deviation and twisting is reduced, and the stability and accuracy of the wire during the cutting process are ensured. When the cutting wire is routed, the wire tension can be more evenly distributed, avoiding cutting problems caused by uneven tension.

[0027] The frame 1 is provided with a long, rectangular base plate 3, on which the worktable 2 is slidably mounted along the front-to-back direction of the worktable 2. In this embodiment, the top of the base plate 3 has a plurality of slide grooves arranged along the front-to-back direction of the worktable 2, and the plurality of slide grooves are spaced apart along the left-to-right direction of the worktable 2.

The two cutting guide wheels 8 are driven by a driving mechanism such as a motor to move the two cutting guide wheels 8 vertically. When the cutting operation is performed, the cutting wire reciprocates under the reciprocating motion of the two wire drums 4. Under the action of the two cutting guide wheels 8, the cutting wire located between the two cutting guide wheels 8 contacts the workpiece to be processed and cuts the workpiece to be processed.

[0029] In the present invention, the first guide group 6 and the second guide group respectively form a winding close to the cutting end of the cutting line, and the transition wheel 5 and the steering wheel 104 arranged near the wire drum 4 for winding the cutting line form a winding away from the cutting end of the cutting line, so that the cutting line has a large tensioning force at both the winding end and the cutting end, so that the cutting line is kept in a tensioned state to ensure the cutting effect. The vertically arranged wire drum 4 can hide the driving mechanism connected to the wire drum 4 inside the equipment, increase the space utilization rate of the equipment, and improve the compactness of the device. In addition, in the prior art, the horizontally arranged wire drum 4 will cause the cutting line to be offset due to the tension when the cutting line is wound up, resulting in a deviation in the tension force. The vertically arranged wire drum 4 has less effect on the position of the cutting line under tension, thereby ensuring the position and direction of the cutting line on the wire drum 4, reducing the problem of tension deviation caused by the offset of the cutting line, and ensuring the cutting effect.
