Description

Technical Field

[0001] The utility model belongs to the field of loop wire cutting, in particular to a vertical loop wire cutting device. Background Art

[0002] Wire sawing usually refers to a processing technology that uses a metal wire with diamond particles (called diamond wire or diamond wire saw) to cut materials. This cutting method is particularly suitable for hard and brittle materials such as stone (marble, granite), glass, ceramics, silicon wafers, composite materials and certain types of metals and plastics. The core advantage of diamond wire cutting is that it can accurately and efficiently cut conductive and non-conductive materials, especially those hard materials that are difficult to handle with traditional cutting tools.

[0003] Diamond wire loops are made of thin metal wires (such as steel wires) as a base, covered with a layer of evenly distributed tiny diamond abrasive particles. During the cutting process, the diamond wire rotates at high speed and applies appropriate tension, removing the material through the grinding action of the diamond particles. Cutting is usually accompanied by the use of coolant to reduce the temperature, remove the debris generated by cutting and extend the life of the wire saw.

[0004] Such operations have traditionally relied on manually operated cutting equipment, such as handheld cutting saws or tabletop cutting machines, which face significant problems such as low efficiency, lack of precision and poor safety when processing large-section or long workpieces.

[0005] Existing circular wire cutting devices often require operators to manually adjust the cutting angle and feed speed throughout the process, which is not only time-consuming and labor-intensive, but also greatly increases the labor intensity of workers. Long-term manual operation is prone to fatigue errors, affecting cutting quality and production efficiency.

[0006] During the cutting process, the high-speed rotating cutting blade will rub against the material violently, generating a large amount of dust and debris. This not only seriously obstructs the operator's vision and affects the cutting accuracy, but also poses a potential threat to the operator's respiratory system. At the same time, the cutting blade has the risk of breaking under high load operation, further exacerbating the safety hazards of the working environment.

[0007] Furthermore, most existing loop cutting equipment adopts the side-feed method. When the cutting is close to completion, the falling pressure caused by the weight of the workpiece can easily cause the loop to be squeezed and broken, increasing the scrap rate. In addition, the manual side-feed method is extremely dependent on the operator's skills and experience. Uneven feeding speed will lead to uneven cutting surface, seriously affecting the quality of the finished product. Moreover, the side-feed method blocks the operator's direct line of sight, making it difficult to monitor the cutting process and not conducive to immediate adjustment and optimization.

[0008] The utility model aims to provide a vertical loop wire cutting device to solve the technical problems of realizing full-automatic loop wire cutting and reducing the loop wire breakage rate during the cutting process.

[0009] In order to achieve the above-mentioned purpose, the specific technical scheme of a vertical loop wire cutting device of the utility model is as follows:

[0010] A vertical loop wire cutting device comprises a supporting structure, a cutting structure connected to a side of the supporting structure;

[0011] The support structure includes a bracket, a slide rail arranged on the side of the bracket, a lifting block moving along the slide rail, and a lifting drive device driving the lifting block to move;

[0012] The cutting structure comprises a cutting shell, a wire wheel structure arranged in the cutting shell, and a cutting line arranged along the wire wheel structure;

[0013] The wire wheel structure includes at least one driving wheel and a plurality of driven wheels; the cutting wire is arranged in a guide groove on the outer periphery of the driving wheel and the driven wheel, and the cutting wire is driven to move between the driving wheel and the driven wheel by the rotation of the driving wheel;

[0015] The side surface of the cutting shell is connected to the lifting block, and the lifting block drives the cutting shell to move, and the object to be cut enters the cutting groove and is cut by the cutting line.

[0016] As a further improvement of the present invention, the cutting structure further includes a tensioning structure, which includes a tensioning wheel connected to the driving wheel and the driven wheel under the guidance of the cutting line, a tensioning connection block connected to the tensioning wheel and passing through the cutting housing and exposed on the back of the cutting housing, a tensioning fixing block arranged on the back of the cutting housing, and a tensioning adjustment rod connecting the tensioning fixing block and the tensioning connection block;

[0017] A tensioning groove is provided on the surface of the cutting shell, the tensioning connecting block passes through the tensioning groove and is connected to the tension wheel and can move in the tensioning groove, and the tensioning adjustment rod adjusts the tensioning connecting block to move relative to the tensioning fixed block in the tensioning groove, thereby driving the tension wheel to move and adjust the tension of the cutting line.

[0018] As a further improvement of the present invention, the tension wheel is arranged between the driving wheel and the driven wheel.

[0019] As a further improvement of the present invention, the cutting line passes through the tension wheel from different sides of the driving wheel and the driven wheel.

[0022] As a further improvement of the present invention, the driving wheel is connected to a rotation driving device, and the rotation driving device is arranged on the outer surface of the cutting shell to drive the driving wheel to rotate.

[0023] As a further improvement of the present invention, the support structure further includes a connecting portion, and the support structure is fixed by the connecting portion.

DETAILED DESCRIPTION

[0039] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0040] Implementation example:

[0041] like Figure 1 As shown, a vertical circular wire cutting device structure includes a cutting structure 200 for cutting an object 300 to be cut from above, and a supporting structure 100 for supporting the cutting structure 200 to move up and down.

[0042] like Figure 2 As shown, the support structure 100 is connected to the overall cutting equipment through the connecting part 150, the bracket 110 stands vertically through the connecting part 150, a vertical slide rail 120 is arranged on the side, the lifting block 130 is slidably connected to the slide rail 120, and the lifting drive device 140 is arranged above the bracket 110. The lifting block 130 moves up and down along the slide rail 120 under the drive of the lifting drive device 140. In this embodiment, the lifting drive device 140 is a lifting motor, and a weight-reducing groove is arranged on the surface of the bracket 110 to reduce the weight of the overall equipment.

[0043] like Figure 3-4As shown, the cutting structure 200 includes a cutting housing 210, a wire wheel structure 220 disposed in the cutting housing 210, a cutting wire 230 placed along the wire wheel structure 220, and a tensioning structure for adjusting the tension of the cutting wire 230. The side of the cutting housing 210 is fixed to the lifting block 130 by bolts, and moves up and down with the lifting block 130. The wire wheel structure 220 includes a driving wheel 221 and a driven wheel 222. In this embodiment, there are two driven wheels 222, namely a first driven wheel 224 and a second driven wheel 225. The two driven wheels 222 are respectively disposed on both sides of the lower part of the cutting housing 210. The cutting wire 230 is disposed in a guide groove on the outer periphery of the driving wheel 221 and the driven wheel 222. The rotation driving device 223 for driving the driving wheel 221 to rotate is disposed on the back of the cutting housing 210 and is connected to the driving wheel 221. In this embodiment, the rotation driving device 223 is a rotating motor. The hollow concave portion at the bottom of the cutting shell 210 forms a cutting groove 211 , and the first driven wheel 224 and the second driven wheel 225 are respectively arranged on both sides of the cutting groove 211 , and the cutting line 230 passes through the cutting groove 211 between the two driven wheels to achieve cutting of the object 300 to be cut in the cutting groove 211 .

[0044] like Figure 5 As shown, the tensioning structure 240 includes a tension wheel 241 disposed in the cutting housing 210, a tensioning connection block 242 exposed on the back of the cutting housing 210, a tensioning fixed block 243 disposed on the back of the cutting housing 210, a tensioning connection rod 244 connecting the tensioning fixed block 243 and the tensioning connection block 242, and a spring 245 disposed between the tensioning fixed block 243 and the tensioning connection block 242. The tensioning connection block 242 passes through the tensioning groove 212 on the surface of the cutting housing 210 and is connected to the tension wheel 241. The tension wheel 241 is disposed between the driving wheel 221 and the driven wheel 222, and is connected to the opposite side of the cutting line 230 relative to the driving wheel 221 and the driven wheel 222, so that the cutting line 230 is in an "S" shape when passing through the driving wheel 221, the tension wheel 241, and the driven wheel 222 in sequence. In this embodiment, the tensioning adjustment rod 244 is an adjusting bolt, which passes through the screw hole of the tensioning connecting block 242 and is connected to the tensioning fixing block 243.

The driving wheel 221, the driven wheel 222, and the tension wheel 241 are fixed in the threaded hole reserved in the cutting housing through the thread at the rotating tail end.

[0046] The control structure of the utility model (not shown in the figure) is movable and can be integrated on the cutting equipment or moved to the ground and placed in a convenient position for operation. The cutting parameters set according to the cutting object are input into the control system, and the lifting drive device and the rotating drive device receive the speed regulation instructions of the control system to make output actions, including but not limited to timed and fixed-point cutting, speed regulation, pause in the middle, and return to the origin after cutting.

[0047] The utility model and the device abandon the traditional lateral feed method and innovatively adopt the vertical feed design, which effectively avoids the problem of squeezing the loop wire when the workpiece falls at the end of cutting and significantly reduces the risk of wire breakage. The vertical feed method also helps to maintain the stability and uniformity of the cutting process, and can ensure the smoothness of the cut surface even when the material thickness changes. Through the integrated automatic propulsion system, the device ensures uniform propulsion during the cutting process, which not only simplifies the difficulty of operation, makes the cutting speed more stable and controllable, but also greatly improves the quality and consistency of the cut surface. At the same time, because the cutting process is more visualized, the operator can monitor the cutting status in real time and make timely adjustments to further ensure the efficiency and accuracy of the cutting operation. It can easily adapt to the cutting needs of a variety of materials and shapes, not only limited to hard materials such as metals and stones, but also meet the fine cutting requirements of precision electronic components or handicrafts, broadening the application field and enhancing market competitiveness.
