Description
Technical Field
[0001] This utility model relates to the field of wire cutting machine technology, and in particular to a high-precision wire cutting machine. Background Technology
[0002] Wire EDM machines are precision cutting equipment widely used in the metal processing and manufacturing industries. They mainly utilize fine wire electrodes to perform high-precision electrical discharge cutting on the workpiece. The working principle of a wire EDM machine is to generate a high-temperature discharge between the electrode wire and the workpiece surface through electrical discharge processing, thereby achieving cutting. This equipment has advantages such as high processing accuracy, good surface finish, and small heat-affected zone. It can cut complex shapes and high-hardness materials. Wire EDM machines are particularly suitable for mold manufacturing, parts processing and other fields, and are commonly used to cut metals, plastics and certain composite materials.
[0003] In the existing technology, the precise movement of the cutting wire in the wire EDM machine during the cutting process still has certain limitations. This is mainly because the wire electrode is easily affected by thermal deformation, mechanical vibration and material properties during processing, which leads to deviations in the cutting path and thus affects the cutting accuracy and surface quality. In addition, when the wire EDM machine is cutting at high speed, the tension and movement control of the electrode wire are insufficient, making it impossible to achieve an ideal motion trajectory, which limits its application in high-precision processing. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision wire cutting machine.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-precision wire cutting machine, comprising a cutting machine body, an internal worktable, two first lead screws rotatably connected to the inner wall of the cutting machine body, each first lead screw having a first driven gear fixed at one end, a first driving gear meshing with the surface of the first driven gear, the first driving gear being driven to rotate by a first motor fixed to the top of the cutting machine body, the two first lead screws threadedly connected to a movable support plate, the inner wall of the movable support plate rotatably connected to two second lead screws, each second lead screw having a second driven gear fixed at one end, a second driving gear meshing with the surface of the second driven gear, the second driving gear being driven to rotate by a second motor fixed to the top of the movable support plate, a movable plate threadedly connected to the surfaces of the two second lead screws, a fixed seat fixed to the bottom of the movable plate, and a cutting seat body located at the bottom of the fixed seat.
[0006] Preferably, a support base is fixed to the top of the inner wall of the cutting base, and a guide shaft is rotatably connected to the inner wall of the support base. A groove is formed on the surface of the guide shaft, and a cutting wire is provided on the inner wall of the groove. An adjusting support frame is fixed to the top of the inner wall of the cutting base. A threaded groove is formed through one side of the adjusting support frame, and a nut is threadedly connected to the inner wall of the threaded groove. One end of the cutting wire is fixed to the nut, and the other end of the cutting wire is fixed to a fixed base, which is fixed to the bottom of the inner wall of the cutting base. In the prior art, wire cutting machines often face the drawback of unadjustable cutting wire tension in practical applications. This problem directly affects cutting quality and efficiency. The wire cutting process requires the electrode wire to maintain a constant tension during operation to ensure a precise cutting trajectory. If the tension is unstable, it will cause the wire to bend, vibrate, or even break during the cutting process, ultimately resulting in processing errors and a decrease in surface quality of the workpiece. In addition, due to the varying hardness and thickness of the cutting materials, a fixed wire tension cannot adapt to the needs of different workpieces, leading to insufficient processing flexibility. To address this problem, this utility model adopts a cutting wire tension adjustment structure. When the cutting wire needs tension adjustment, the guide shaft... The rotating nut moves away from the guide shaft, tensioning the cutting wire. When tension needs to be loosened, rotating the nut moves it closer to the guide shaft, loosening the cutting wire. This significantly improves cutting quality and efficiency. By introducing an adjustable wire tension system, the electrode wire maintains constant tension during cutting, ensuring the accuracy of the cutting trajectory and reducing the risk of wire bending, vibration, and breakage. Furthermore, the adjustable tension, adaptable to different material hardness and thickness, enhances processing flexibility, enabling the wire EDM machine to meet various workpiece requirements and ultimately achieve higher processing accuracy and excellent surface quality.
[0007] Preferably, the bottom of the cutting machine body is provided with a support groove, and a third lead screw is rotatably connected to the inner wall of the support groove. The third lead screw is driven to rotate by a third motor, and the third motor is fixed to the inner wall of the support groove. An X-shaped bearing seat is threadedly connected to the surface of the third lead screw, and a universal wheel is fixed to the bottom of the X-shaped bearing seat. In existing technologies, the main design of wire EDM machines often lacks necessary mobility, making simple spatial adjustments impossible within the factory. This limitation not only affects factory production efficiency but also makes it difficult to flexibly change machine layout and workpiece processing procedures. Especially when switching between different processes or products, it increases time and labor costs. To address these issues, this invention adopts a simple mobility structure. When the wire EDM machine needs to be moved, the third motor is started. Driven by the third motor, the third lead screw rotates, thereby moving the X-shaped support on the surface. Once the X-shaped support and the casters are in full contact with the ground, the main body of the cutting machine can be moved. This allows for more flexible factory layout and process switching, significantly improving production efficiency. Enhancing the ease of equipment mobility reduces the time and labor costs required for machine rearrangement and adjustment, enabling factories to respond more quickly to order changes and market demands, optimize production processes, and ultimately improve overall competitiveness.
[0008] Preferably, the diameter of the first driving gear is larger than the diameter of the first driven gear, and the diameter of the second driving gear is larger than the diameter of the second driven gear. This increases the rotational speed and reduces the torque, thereby improving the operating accuracy of the system. The larger driving gear can transmit power more smoothly, reducing impact and wear during gear meshing, thus reducing errors and improving transmission stability. Furthermore, this configuration optimizes power transmission, improves overall efficiency, reduces energy loss, and further enhances operating accuracy.
[0009] Preferably, the work surface has a smooth design. A smooth surface can effectively reduce friction, making it easier for objects to slide and move, thereby improving work efficiency. In addition, a smooth surface is easy to clean and maintain, preventing the accumulation of dirt and debris and keeping the work environment clean.
[0010] Preferably, the bottom of the cutting machine body is provided with anti-slip texture. The anti-slip texture increases the contact area with the ground, effectively improving the stability and friction of the equipment. This design can reduce the risk of slippage caused by vibration or pressure during the cutting process, ensuring operational safety and accuracy. At the same time, the increased contact area also helps to evenly distribute gravity, reduce the pressure on the ground, and further improve the service life and performance of the cutting machine.
[0011] Preferably, the cutting machine body has gripping grooves on both sides. The presence of gripping grooves allows the operator to hold the cutting machine more firmly, facilitating operation, and effectively reducing labor intensity, especially when frequent movement or adjustment of the cutting position is required.
[0012] Beneficial effects:
[0013] 1. In existing technologies, the precise movement of the cutting wire in wire EDM machines during the cutting process still has certain limitations. This is mainly because the wire electrode is easily affected by thermal deformation, mechanical vibration, and material properties during processing, leading to deviations in the cutting path and thus affecting cutting accuracy and surface quality. In addition, when wire EDM machines cut at high speeds, the tension and movement control of the electrode wire are insufficient, making it impossible to achieve an ideal motion trajectory, which limits its application in high-precision processing. To address these issues, this utility model adopts an adjustable cutting track structure to effectively reduce the impact of thermal deformation, mechanical vibration, and material properties on the cutting path, thereby improving cutting accuracy and surface quality. Furthermore, enhancing the tension and movement control of the electrode wire, especially during high-speed cutting, can achieve a more ideal motion trajectory, broadening the application range of wire EDM machines in the field of high-precision processing and significantly improving their processing efficiency and product quality.
[0014] 2. In existing technologies, wire EDM machines often face the drawback of unadjustable wire tension in practical applications. This problem directly affects cutting quality and efficiency. The wire EDM process requires the electrode wire to maintain constant tension during operation to ensure a precise cutting trajectory. If the tension is unstable, it can lead to wire bending, vibration, or even breakage during the cutting process, ultimately causing machining errors and a decrease in surface quality of the workpiece. In addition, due to the varying hardness and thickness of the cutting materials, a fixed wire tension cannot meet the needs of different workpieces, resulting in insufficient processing flexibility. To address these issues, this invention adopts a wire tension adjustment structure to significantly improve cutting quality and efficiency.

Furthermore, the adjustable tension, adaptable to different material hardness and thickness, improves processing flexibility, enabling the wire EDM machine to meet the needs of various workpieces and ultimately achieve higher machining accuracy and excellent surface quality.
[0015] 3. In existing technologies, the main design of wire EDM machines often lacks necessary mobility, making it impossible to make simple spatial adjustments within the factory. This limitation not only affects the factory's production efficiency but also makes it difficult to flexibly change the machine layout and workpiece processing flow. Especially when different processes or products need to be switched, it increases time and labor costs. To address these issues, this utility model adopts a simple movable structure, which enables more flexible factory layout and process switching, thereby significantly improving production efficiency. Enhancing the equipment's mobility will reduce the time and labor costs required for machine rearrangement and adjustment, allowing the factory to respond more quickly to order changes and market demands, optimize production processes, and ultimately improve overall competitiveness.

Detailed Implementation
[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:
[0026] Reference Figure 1-5A high-precision wire cutting machine includes a machine body 1, with a worktable 4 inside. Two first lead screws 101 are rotatably connected to the inner wall of the machine body 1. A first driven gear 102 is fixed to one end of each of the two first lead screws 101. A first driving gear 103 meshes with the surface of the first driven gear 102. The first driving gear 103 is driven to rotate by a first motor 104, which is fixed to the top of the machine body 1. A movable support plate 105 is threadedly connected to the two first lead screws 101. Two second lead screws 106 are rotatably connected to the inner wall of the support plate 105. A second driven gear 111 is fixed to one end of each of the two second lead screws 106. A second driving gear 107 meshes with the surface of the second driven gear 111. The second driving gear 107 is driven to rotate by a second motor 108. The second motor 108 is fixed to the top of the movable support plate 105. A movable plate 109 is threadedly connected to the surface of the two second lead screws 106. A fixed seat 112 is fixed to the bottom of the movable plate 109. A cutting seat 110 is provided at the bottom of the fixed seat 112. In existing technologies, the precise movement of the cutting wire in wire EDM machines during the cutting process still has certain limitations. This is mainly because the wire electrode is easily affected by thermal deformation, mechanical vibration, and material properties during processing, leading to deviations in the cutting path and thus affecting cutting accuracy and surface quality. Furthermore, at high-speed cutting, the tension and movement control of the electrode wire are insufficient, making it impossible to achieve an ideal motion trajectory, thus limiting its application in high-precision machining. To address these issues, this invention employs an adjustable cutting track structure. When cutting is performed, the first motor 104 is started, and the first drive gear 103 rotates under the drive of the first motor 104, thereby... The two driven gears 102 rotate, which in turn drives the two lead screws 101 to rotate, thereby moving the movable support plate 105. This allows the movable support plate 105 to move in the direction of the lead screws 101. The second motor 108 is then started, and the second drive gear 107 rotates under its drive. The rotation of the second drive gear 107 drives the two driven gears 111 to rotate, which in turn drives the two lead screws 106 to rotate. This drives the movable plate 109 to move in the direction of the lead screws 106, thereby allowing the bottom cutting assembly to move arbitrarily in both directions.
[0027] A support base 2 is fixed to the top of the inner wall of the cutting base 110. A guide shaft 201 is rotatably connected to the inner wall of the support base 2. A groove is opened on the surface of the guide shaft 201. A cutting line 202 is provided on the inner wall of the groove. An adjusting support frame 204 is fixed to the top of the inner wall of the cutting base 110. A threaded groove is opened through one side of the adjusting support frame 204. A nut 205 is threadedly connected to the inner wall of the threaded groove. One end of the cutting line 202 is fixed to one side of the nut 205. The other end of the cutting line 202 is fixed to a fixed base 203. The fixed base 203 is fixed to the bottom of the inner wall of the cutting base 110. In existing technologies, wire EDM machines often face the drawback of unadjustable wire tension in practical applications. This problem directly affects cutting quality and efficiency. The wire EDM process requires the electrode wire to maintain constant tension during operation to ensure a precise cutting trajectory. If the tension is unstable, it can lead to wire bending, vibration, or even breakage during the cutting process, ultimately causing machining errors and a decrease in surface quality of the workpiece. In addition, due to the varying hardness and thickness of the cutting materials, a fixed wire tension cannot meet the needs of different workpieces, resulting in insufficient processing flexibility. To address these issues, this invention employs a wire tension adjustment structure. When the wire tension needs to be tightened, the nut 205 is rotated, causing it to move away from the guide shaft 201, thus tightening the wire 202. When the tension needs to be loosened, the nut 205 is rotated, causing it to move closer to the guide shaft 201, thus loosening the wire 202.
[0028] The bottom of the main body 1 of the cutting machine is provided with a support groove 3. The inner wall of the support groove 3 is rotatably connected to a third lead screw 301. The third lead screw 301 is driven to rotate by a third motor 302. The third motor 302 is fixed to the inner wall of the support groove 3. The surface of the third lead screw 301 is threadedly connected to an X-shaped bearing seat 303. The bottom of the X-shaped bearing seat 303 is fixed with a universal wheel 304. In the prior art, the main design of wire EDM machines often lacks necessary mobility, making it impossible to make simple spatial adjustments within the factory. This limitation not only affects the factory's production efficiency but also makes it difficult to flexibly change the machine layout and workpiece processing flow. Especially when different processes or products need to be switched, it increases time and labor costs. To address this problem, this utility model adopts a simple mobility structure. When the wire EDM machine needs to be moved, the third motor 302 is started. Driven by the third motor 302, the third lead screw 301 rotates, thereby driving the X-shaped support 303 on the surface to move. After the X-shaped support 303 drives the caster 304 to fully contact the ground, the main body of the cutting machine 1 can be moved.
[0029] The diameter of the first driving gear 103 is larger than that of the first driven gear 102, and the diameter of the second driving gear 107 is larger than that of the second driven gear 111. This increases the rotational speed and reduces the torque, improving the system's operational accuracy. Larger driving gears transmit power more smoothly, reducing impact and wear during gear meshing, thus minimizing errors and improving transmission stability. Furthermore, this configuration optimizes power transmission, improves overall efficiency, reduces energy loss, and further enhances operational precision. The worktable 4 features a smooth design; this smooth surface effectively reduces friction, making it easier for objects to slide and move, thereby improving work efficiency. Additionally, the smooth surface facilitates cleaning and maintenance. It can prevent the accumulation of dirt and debris, keeping the working environment clean. The bottom of the cutting machine body 1 is provided with anti-slip texture. The anti-slip texture increases the contact area with the ground, which effectively improves the stability and friction of the equipment. This design can reduce the risk of slippage caused by vibration or pressure during the cutting process, ensuring operational safety and accuracy. At the same time, the increased contact area also helps to evenly distribute gravity, reduce the pressure on the ground, and further improve the service life and performance of the cutting machine. Both sides of the cutting machine body 1 are provided with gripping grooves 5. The presence of gripping grooves allows the operator to hold the cutting machine more firmly, making it easier to operate. Especially when it is necessary to frequently move or adjust the cutting position, it can effectively reduce labor intensity.
[0030] The working principle of this utility model is as follows: When performing a cutting operation, the first motor 104 is started. Driven by the first motor 104, the first driving gear 103 rotates, which in turn drives the two first driven gears 102 to rotate. The rotation of the first driven gears 102 drives the two first lead screws 101 to rotate, which in turn drives the movable support plate 105 to move, thereby adjusting the movement of the movable support plate 105 in the direction of the first lead screws 101. The second motor 108 is then started. Driven by the second motor 108, the second driving gear 107 rotates, which in turn drives the two second driven gears 111 to rotate, thereby driving the two second lead screws 106 to rotate, and driving the movable plate 109 to rotate in the direction of the second lead screws 106. The cutting machine moves in two directions, allowing the bottom cutting assembly to move freely in both directions. When the cutting wire needs tension adjustment, the nut 205 is rotated, causing it to move away from the guide shaft 201 and tension the cutting wire 202. When the tension needs to be loosened, the nut 205 is rotated, causing it to move closer to the guide shaft 201 and loosen the cutting wire 202. When the wire cutting machine needs to be moved, the third motor 302 is started, and the third lead screw 301 rotates under the drive of the third motor 302, which in turn moves the X-shaped support 303 on the surface. Once the X-shaped support 303 and the caster 304 are in full contact with the ground, the main body of the cutting machine 1 can be moved.
[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
