Description

Technical Field

[0001] This utility model relates to the field of linear cutting equipment technology, specifically a linear cutting machine with a multi-station structure. Background Technology

[0002] In existing linear cutting technologies, the traditional reel layout has significant drawbacks for dual-station machining requirements: to achieve cutting at both stations, the cutting line is typically guided by only two reels. Due to the large distance between the two reels, the cutting line spans a long distance within the working area. When the cutting line cuts the workpiece, the reaction force from the workpiece easily causes the long-span cutting line to bend and deform, disrupting the parallelism between the cutting line and the worktable surface and directly affecting the cutting rate and processing efficiency of both stations. Utility Model Content

[0003] The purpose of this invention is to provide a linear cutting machine that solves the technical problem of difficulty in ensuring the parallelism between the cutting line and the multi-station worktable.

[0004] This utility model can be achieved through the following technical solutions:

[0005] A linear cutting machine, comprising:

[0006] The frame serves as the carrier for the linear cutting machine;

[0007] A workbench is horizontally mounted on a frame. At least two workstations are arranged side-by-side on either side of the workbench, designated as a first workstation and a second workstation. At least one set of reels is rotatably fixed to the frame and positioned above the workbench. The reel set includes a first reel, a second reel, and a third reel. The third reel is located between the first and second reels. The lowest points of the first and second reels are at the same horizontal level, and the line connecting their lowest points is parallel to the workbench surface. The distance between the lowest point of the third reel and the workbench surface is no greater than the distance between the lowest point of the first reel and the workbench surface. The first and third reels, and the second and third reels, respectively form a first working area and a second working area, each corresponding to a first workstation and a second workstation, respectively.

[0008] The cutting line passes through the first, third, and second thread reels in sequence, forming a closed loop structure.

[0009] In the aforementioned linear cutting machine, the first, second, and third wire wheels are arranged with equal diameters, and the center of the first wire wheel is at the same height as the center of the second wire wheel. The center of the third wire wheel is located on the line connecting the centers of the first and second wire wheels, or the horizontal level of the line connecting the centers of the first and second wire wheels is higher than the horizontal level of the center of the third wire wheel.

[0010] In the aforementioned linear cutting machine, there are two sets of wire sheaves, and each set includes a first wire sheave, a second wire sheave, and a third wire sheave. The two first wire sheaves, two second wire sheaves, and two third wire sheaves in the two sets are connected by a first rotating shaft, a second rotating shaft, and a third rotating shaft, respectively. The two first wire sheaves are connected to both ends of the first rotating shaft along the axial direction, the two second wire sheaves are connected to both ends of the second rotating shaft along the axial direction, and the two third wire sheaves are connected to both ends of the third rotating shaft along the axial direction.

[0011] In the aforementioned linear cutting machine, at least one tensioning mechanism is also included. The output end of the tensioning mechanism is connected to a tensioning wheel, and the cutting lines passing through the first, second, and third thread wheels simultaneously pass through the tensioning wheel to form a closed ring structure. The rotation of the tensioning wheel causes the cutting lines passing through the lowest point of the first thread wheel and the cutting lines passing through the lowest point of the third thread wheel to be collinear.

[0012] In the aforementioned linear cutting machine, a tensioning mechanism further includes a tensioning motor connected to the frame, a tensioning rod connected to the output end of the tensioning motor, and a tensioning wheel connected to the tensioning rod, wherein the output end of the tensioning motor and the tensioning wheel are respectively connected to the two ends of the tensioning rod.

[0013] In the aforementioned linear cutting machine, there are two tensioning mechanisms, and each tensioning mechanism corresponds to one of the two sheave groups. The centers of the tensioning wheels in the two tensioning mechanisms are at the same horizontal level, and the line connecting the centers of the two tensioning wheels is parallel to the axis of the first rotating shaft.

[0014] In the aforementioned linear cutting machine, a first distance is formed between the centers of two first thread rollers, a second distance is formed between the centers of two second thread rollers, a third distance is formed between the centers of two third thread rollers, and a fourth distance is formed between the centers of two tension rollers, wherein the first, second, third, and fourth distances are all equal to each other.

[0015] The linear cutting machine described above also includes a drive mechanism, which includes a drive motor mounted on the frame. The output end of the drive motor is connected to an output shaft, and a drive wheel is nested on the output shaft. The diameter of the drive wheel is larger than the diameter of the wire wheel. The cutting wire passes through the first wire wheel, the second wire wheel, and the third wire wheel in sequence via the drive wheel to form a closed ring structure.

[0016] In the aforementioned linear cutting machine, there are two drive wheels, and the two drive wheels are used in conjunction with two sets of wire wheels. The two drive wheels are connected by a fourth rotating shaft, and the two drive wheels are located at both ends of the fourth rotating shaft along the axial direction of the fourth rotating shaft. A fifth distance is formed between the two drive wheels, and this fifth distance is equal to the first distance.

[0017] In the aforementioned linear cutting machine, at least one water supply pipe is also provided on the frame. One end of the water supply pipe is connected to a water tank, and the other end of the water supply pipe is located between the first and third wire reels, or between the second and third wire reels. A groove is provided on the water supply pipe, in which the cutting line is embedded.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Ensure parallelism in the cuts:

[0020] By setting a third thread roller between the two workstations, the path of the cutting line in both the first and second working areas is precisely guided, ensuring parallelism with the worktable surface and reducing the deformation of the cutting line. This solves the problem of large deviation between the parallelism of the cutting line and the processing table surface caused by the lack of intermediate guidance in traditional dual-station equipment, thus ensuring the processing efficiency of the workstation.

[0021] 2. Increase the cutting line speed to improve processing efficiency:

[0022] The diameter of the drive wheel is larger than that of the spool. With the same drive motor speed, the linear speed of the cutting line can be increased by a larger circumferential motion distance, reducing the cutting time per unit time. This is especially suitable for the rapid cutting of high-hardness materials, significantly improving processing efficiency.

[0023] 3. Enhance tension stability and ensure cutting quality.

[0024] The tensioning mechanism uses a tensioning motor to drive a tensioning rod, which in turn moves a tensioning wheel to adjust the tension of the cutting wire. At the same time, the tensioning wheel ensures that the cutting wire remains collinear between the first and third thread wheels, preventing slack in the cutting wire due to tension fluctuations and ensuring a stable cutting process.

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] like Figures 1 to 3As shown, the present invention provides a linear cutting machine, comprising: a frame 100, serving as the carrier of the linear cutting machine; a worktable 10, horizontally mounted on the frame 100, with at least two workstations arranged side-by-side on both sides of the worktable 10, wherein the two workstations are a first workstation 11 and a second workstation 12; and at least one set of wire reels, rotatably fixedly mounted on the frame 100 and located above the worktable 10, wherein the wire reel set includes a first wire reel 20, a second wire reel 21, and a third wire reel 22; the third wire reel 22 is located between the first wire reel 20 and the second wire reel 21, and the lowest point of the first wire reel 20 is adjacent to the second wire reel. The lowest points of 21 are at the same horizontal level, and the line connecting the lowest points of the two is parallel to the surface of the workbench 10. The distance between the lowest point of the third thread wheel 22 and the surface of the workbench 10 is not greater than the distance between the lowest point of the first thread wheel 20 and the surface of the workbench 10. The first working area and the second working area are formed between the first thread wheel 20 and the third thread wheel 22, and between the second thread wheel 21 and the third thread wheel 22, respectively. The first working area and the second working area correspond one-to-one with the first station 11 and the second station 12, respectively. The cutting line 23 passes through the first thread wheel 20, the third thread wheel 22 and the second thread wheel 21 in sequence, forming a closed ring structure.

[0037] This utility model provides a linear cutting machine that uses diamond wire as the cutting wire 23. By setting a third wire wheel 22 between the first station 11 and the second station 12, the path of the cutting wire 23 in both the first working area (between the first wire wheel 20 and the third wire wheel 22) and the second working area (between the second wire wheel 21 and the third wire wheel 22) is precisely guided. Since the lowest point of the first wire wheel 20 and the lowest point of the second wire wheel 21 are at the same horizontal level and the line connecting them is parallel to the table surface of the worktable 10, and the distance between the lowest point of the third wire wheel 22 and the table surface is no greater than the distance between the lowest point of the first wire wheel 20 and the table surface, it not only ensures that the cutting wire 23 remains parallel to the table surface of the worktable 10, reducing the deformation of the cutting wire 23 and solving the problem of the cutting wire 23 not being parallel to the processing table surface due to the lack of intermediate guidance in traditional dual-station equipment, but also the setting of the third wire wheel 22 can effectively support the cutting wire 23, reduce the vibration caused by the high-speed movement of the wire during the cutting process, further improve the cutting stability, and ensure the processing efficiency and accuracy of the two stations.

[0038] Preferably, the first spool 20, the second spool 21, and the third spool 22 are arranged with the same diameter. This design ensures that the contact arc of the cutting wire 23 is consistent when it passes over each spool, resulting in uniform force distribution and avoiding localized wear caused by differences in spool diameter, thus extending the service life of the cutting wire 23. Simultaneously, the center of the first spool 20 is set at the same height as the center of the second spool 21. Combined with the specific position of the center of the third spool 22—either located on the connecting line between the centers of the first spool 20 and the second spool 21, or below this connecting line (i.e., the horizontal height of the connecting line between the centers of the first spool 20 and the second spool 21 is higher than the horizontal height of the center of the third spool 22)—this further optimizes the cutting path. When the center of the third spool 22 is on the connecting line, a symmetrical layout is formed, ensuring that the tension of the cutting wire 23 in both working areas is completely consistent; when it is below the connecting line, a moderate concavity can enhance the cutting pressure. Both layouts enhance the parallelism between the cutting line 23 and the worktable 10, improve the cutting accuracy of the dual-station setup, and facilitate standardized production and replacement of the wire reels, reducing maintenance costs.

[0039] It is worth mentioning that there are two sets of thread sheaves. Each set includes a first thread sheave 20, a second thread sheave 21, and a third thread sheave 22. The two first thread sheaves 20 in the two sets are connected by a first rotating shaft 24, the two second thread sheaves 21 are connected by a second rotating shaft 25, and the two third thread sheaves 22 are connected by a third rotating shaft 26. The two first thread sheaves 20 are connected to both ends of the first rotating shaft 24 along its axial direction, the two second thread sheaves 21 are connected to both ends of the second rotating shaft 25 along its axial direction, and the two third thread sheaves 22 are connected to both ends of the third rotating shaft 26 along its axial direction. This structure achieves synchronous movement of the two sets of thread sheaves by sharing a rotating shaft, ensuring that the running trajectory of the cutting lines 23 on both sides is completely consistent, improving the consistency of multi-station processing. At the same time, the axially symmetrical distribution of the thread sheaves can increase the number of workpieces processed in a single operation, significantly improving processing efficiency. Furthermore, the unified rotating shaft design reduces transmission errors, lowers assembly difficulty, and facilitates equipment maintenance and debugging.

[0040] It is worth mentioning that this utility model also includes at least one tensioning mechanism 40, the output end of which is connected to a tensioning wheel 29. The cutting wire 23, which passes through the first thread wheel 20, the second thread wheel 21, and the third thread wheel 22, simultaneously passes through the tensioning wheel 29, forming a closed annular structure. By rotating the tensioning wheel 29, the tension of the cutting wire 23 can be precisely adjusted.

[0041] Preferably, a tensioning mechanism 40 further includes a tensioning motor 41 connected to the frame 100, a tensioning rod 42 connected to the output end of the tensioning motor 41, and a tensioning wheel 29 connected to the tensioning rod 42, wherein the output end of the tensioning motor 41 and the tensioning wheel 29 are respectively connected to the two ends of the tensioning rod 42. The tensioning motor 41 can drive the tensioning wheel 29 to move flexibly through the tensioning rod 42, thereby realizing dynamic adjustment of the tension of the cutting wire 23. Compared with the traditional manual adjustment method, it has higher adjustment accuracy and faster response, and can compensate for tension fluctuations of the cutting wire 23 caused by wear or temperature changes in real time. The rigid structure of the tensioning rod 42 ensures the stability of power transmission, avoids lag or shaking during the adjustment process, and ensures that the cutting wire 23 is always in the optimal tension state.

[0042] Preferably, in this embodiment, there are two tensioning mechanisms 40, each corresponding to one of the two sheave groups. The centers of the tensioning wheels 29 in the two tensioning mechanisms 40 are at the same horizontal level, and the line connecting the centers is parallel to the axis of the first rotating shaft 24. Simultaneously, the first distance between the centers of the two first sheaves 20, the second distance between the centers of the two second sheaves 21, the third distance between the centers of the two third sheaves 22, and the fourth distance between the centers of the two tensioning wheels 29 are all equal. This symmetrical layout ensures that the cutting lines 23 of the two sheave groups are subjected to balanced force. The design of the tensioning wheels 29 further enhances the parallel trajectory of the cutting lines 23, and, in conjunction with the equidistantly distributed sheave groups, improves the stability of the equipment operation and processing efficiency.

[0043] Preferably, the present invention further includes a drive mechanism 30, which includes a drive motor 31 mounted on the frame 100. The output end of the drive motor 31 is connected to an output shaft, and two drive wheels 28 are nested on the output shaft. The two drive wheels 28 are used in conjunction with two sets of thread reels and are connected by a fourth rotating shaft 27, located at both ends along the axial direction of the fourth rotating shaft 27. The diameter of the drive wheel 28 is larger than that of the thread reel. The cutting wire 23 passes through the first thread reel 20, the second thread reel 21, and the third thread reel 22 in sequence via the drive wheel 28, forming a closed ring structure. The fifth distance formed between the two drive wheels 28 is equal to the first distance. This design allows the cutting wire 23 of the two sets of thread reels to obtain a balanced driving force. The larger diameter drive wheel 28 can increase the linear speed of the cutting wire 23 at the same rotation speed, reducing cutting time, while increasing the contact area with the cutting wire 23 and reducing slippage. The fourth rotating shaft 27 ensures that the two drive wheels 28 rotate synchronously. With the equidistant layout, it ensures the consistency of dual-station processing and improves the stability and efficiency of the equipment.

[0044] Preferably, at least one water supply pipe 32 is also provided on the frame 100. One end of the water supply pipe 32 is connected to the water tank 33, and the other end is located between the first wire reel 20 and the third wire reel 22 or between the second wire reel 21 and the third wire reel 22. The water supply pipe 32 is provided with a groove 34, and the cutting wire 23 is embedded in the groove 34. The design of the groove 34 ensures that the cutting wire 23 is always in water in the water supply pipe 32, ensuring that the cutting wire 23 can continuously contact water during high-speed movement. This structure allows the cutting wire 23 to fully carry water into the cutting kerf of the first and second working areas. On the one hand, the water flow quickly removes the debris generated during cutting, preventing debris from accumulating in the kerf and hindering cutting; on the other hand, the water flow can directly cool the cutting wire 23 and the cutting part of the workpiece, reducing wear of the cutting wire 23 and thermal deformation of the workpiece caused by frictional heat, further improving cutting quality and efficiency.

[0045] Preferably, four protective doors 50 are provided around the work area. The bottom edge of the protective door 50 is lower than the work surface. A guide channel is provided on the bottom side of the protective door facing the work area. The guide channel extends along the width direction of the corresponding protective door and communicates with the sewage tank 33.

[0046] Preferably, this utility model is a linear cutting machine, including a frame 100, a worktable 10, at least one set of wire reels and a cutting wire 23. The worktable 10 has a first station 11 and a second station 12 arranged side by side. The wire reel set includes a first wire reel 20, a second wire reel 21, and a third wire reel 22, with the third wire reel 22 located between the first two. The three reels work together to form a closed ring structure of the cutting wire 23 corresponding to the two stations, ensuring the parallelism of the cutting wire 23 with the worktable surface. The first wire reel 20, the second wire reel 21, and the third wire reel 22 have the same diameter, and the centers of the first wire reel 20 and the second wire reel 21 are at the same height. The third thread wheel 22 optimizes the cutting path by positioning its center. The thread wheel group consists of two sets connected by a rotating shaft to achieve synchronous movement. It includes at least one tensioning mechanism 40, whose tensioning wheel 29 adjusts the tension of the cutting line 23. The tensioning motor 41 and tensioning rod 42 improve the adjustment accuracy. The two tensioning mechanisms 40 are symmetrically arranged. The two thread wheel groups are equidistant from each other. The drive wheel 28 of the drive mechanism 30 has a larger wheel diameter to increase the line speed. The two drive wheels 28 are symmetrically distributed. The water supply pipe 32 and the groove 34 allow the cutting line 23 to operate with water. Overall, the structure is optimized to improve the parallelism, efficiency, and stability of the cutting, ensuring the processing quality.
