Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0021] This embodiment describes a single-wire cutting machine capable of processing irregular cross-sections, which can cut irregular cross-sections of workpieces.

[0022] like Figure 1 and Figure 2 As shown, the single-wire cutting machine includes a frame 1, a worktable assembly 3, a wire take-up and unwinding mechanism 5, a wire laying mechanism 6, a tensioning mechanism 7, a cutting wheel assembly, a lifting mechanism 12, a spraying mechanism 13, and a control box 14. The cutting wheel assembly includes a drive wheel 8, a driven wheel 9, a transition guide wheel 10, and a guide wheel 11.

[0023] The frame 1 serves as the support frame for the single-wire cutting machine, supporting all parts and ensuring the stability of the cutting motion. Four feet 2 are threaded onto the bottom corners of the frame 1. Adjusting the height of the feet 2 allows for adjustment of the overall level of the single-wire cutting machine, improving cutting positioning accuracy and thus cutting precision.

[0024] The worktable assembly 3 is used to hold the workpiece to be processed and to drive the workpiece to feed. In this embodiment, the worktable assembly 3 is a three-axis worktable, such as... Figure 3 As shown, the worktable assembly 3 includes a first drive motor 3.1, a transverse lead screw 3.2, a sliding seat 3.3, a horizontal guide rail 3.4, a mounting base 3.5, a fixed base 3.6, a front travel limit switch 3.7, a rear travel limit switch 3.8, a support frame 3.9, a second drive motor 3.10, a sliding table 3.11, a base 3.12, a third drive motor 3.13, a rotary seat 3.14, and a V-block 3.15.

[0025] The first drive motor 3.1 is mounted on the frame 1, and its output shaft is connected to the transverse lead screw 3.2. The sliding seat 3.3 is bolted to the transverse lead screw 3.2. The first drive motor 3.1 drives the sliding seat 3.3 to move horizontally along the X-axis through the transverse lead screw 3.2. Preferably, the transverse lead screw 3.2 is coaxial with the frame 1 along the X-axis. To ensure the support stability of the transverse lead screw 3.2 and its coaxiality with the output shaft of the first drive motor 3.1, two mounting seats 3.5 at both ends of the transverse lead screw 3.2 are fixed to the frame 1. The mounting seats 3.5 have bearing holes, and bearings are installed in the bearing holes. The two ends of the transverse lead screw 3.2 pass through the bearings, and the transverse lead screw 3.2 is stably supported by the mounting seats 3.5.

[0026] Two horizontal guide rails 3.4 on both sides of the transverse lead screw 3.2 are symmetrically press-fitted onto the frame 1 via two fixed seats 3.6. The bottom sides of the sliding seat 3.3 are slidably mounted on the horizontal guide rails 3.4 respectively. When the sliding seat 3.3 moves horizontally, it slides along the horizontal guide rails 3.4 to ensure stable movement of the sliding seat 3.3.

[0027] In this embodiment, a front travel limit switch 3.7 and a rear travel limit switch 3.8 are installed at predetermined positions on the frame 1 between two fixed seats 3.6 to monitor the maximum forward and backward travel of the sliding seat 3.3. The front travel limit switch 3.7 and the rear travel limit switch 3.8 feed back the monitored limit position information to the control box 14, and the control box 14 controls the first drive motor 3.1 to stop according to the limit position information.

[0028] The support frame 3.9 is mounted on the front surface of the sliding seat 3.3. The second drive motor 3.10, the longitudinal lead screw, and the longitudinal slide rail are respectively mounted on the support frame 3.9. The second drive motor 3.10 is threaded to one side of the sliding table 3.11 via the longitudinal lead screw, and the other side of the sliding table 3.11 is slidably mounted on the longitudinal slide rail. The longitudinal lead screw is parallel to the longitudinal slide rail and perpendicular to the axial direction of the transverse lead screw 3.2. The second drive motor 3.10 can drive the sliding table 3.11 to move longitudinally along the Y-axis via the longitudinal lead screw.

[0029] The base 3.12 is mounted on the sliding table 3.11. A U-shaped support structure is located at the center of the lower part of the base 3.12 along the X-axis. Within this U-shaped support structure, a third drive motor 3.13 is mounted on the sliding table 3.11. The output shaft of the third drive motor 3.13 is connected to one end of a rotating shaft, and the other end of the rotating shaft is mounted on the base 3.12 via a bearing. The base 3.12 has an arc-shaped recess in its center. The bottom of the rotating seat 3.14 is placed within this arc-shaped recess and is connected to the rotating shaft via a spline. The rotating seat 3.14 is located below the cutting line within the cutting area. The third drive motor 3.13 can drive the rotating seat 3.14 to rotate around the X-axis via the rotating shaft.

[0030] V-blocks 3.15 are symmetrically arranged on the front and back sides above the rotating seat 3.14. The workpiece 4 is placed on the V-blocks 3.15 and fixed by pasting.

[0031] In this embodiment, the first drive motor 3.1, the second drive motor 3.10, and the third drive motor 3.13 are respectively connected to the control box 14 and can operate individually or simultaneously under the control of the control box 14. After the workpiece 4 is attached to the V-block 3.15, the control box 14 controls one or more of the first drive motor 3.1, the second drive motor 3.10, and the third drive motor 3.13 to operate, thereby realizing the synchronous movement of the workpiece along a single axis or both axes of X and Y, and rotation around the X-axis, which facilitates the cutting of the workpiece 4 into irregular cross-sections by the cutting line.

[0032] A take-up and unwind mechanism 5, a wire laying mechanism 6, and a tensioning mechanism 7 are installed on both sides of the frame 1. Guide wheels 11 are symmetrically installed at the front ends of both sides of the frame 1. A lifting mechanism 12 is provided at the front end of the frame 1. The driving wheels 8 and driven wheels 9 on both sides of the X-axis of the worktable assembly 3 are symmetrically installed on the lifting frame of the lifting mechanism 12. Two transition guide wheels 10 are symmetrically installed on the outer sides of the driving wheels 8 and driven wheels 9 on the lifting frame. The driving wheels 8, driven wheels 9, and transition guide wheels 10 are axially aligned and on the same horizontal surface.

[0033] The cutting wire extends from the take-up and unwind mechanism 5 on one side, passes sequentially around the wire laying mechanism 6, tension mechanism 7, and guide wheel 11, then turns to the front end of the frame 1, passing sequentially around the transition guide wheel 10, drive wheel 8, driven wheel 9, and transition guide wheel 10 again. It then turns to the other side of the frame 1, passes around the guide wheel 11, tension mechanism 7, and wire laying mechanism 6, and finally winds onto the take-up and unwind mechanism 5. Driven by the lifting mechanism 12, the drive wheel 8, driven wheel 9, and transition guide wheel 10 rise and fall synchronously, thus achieving the lifting and feeding of the cutting wire. The cutting wire between the drive wheel 8 and driven wheel 9 is positioned above the workpiece 4, cutting the workpiece below during the feeding process.

[0034] The drive wheel 8 can be driven by a separate drive unit. The drive unit of the drive wheel 8, the wire take-up and release mechanism 5, the wire laying mechanism 6, the tension mechanism 7, and the lifting mechanism 12 are all connected to the control box 13, which controls the movement of each component. The two wire take-up and release mechanisms 5 alternately take up and release the wire, causing the cutting wire to run back and forth, cutting the workpiece below. The wire laying mechanism 6 is used to release the cutting wire evenly and continuously from the wire take-up and release mechanism 5, or to wind it back onto the wire take-up and release mechanism 5 at fixed intervals. The tension mechanism 7 is used to ensure that the tension of the cutting wire is constant and stable.

[0035] In this embodiment, the spraying mechanism 13 includes a coolant supply mechanism 13.1 and nozzles 13.2. Multiple nozzles 13.2 are evenly spaced and installed on the lifting frame between the driving wheel 8 and the driven wheel 9. These nozzles 13.2 are connected to the outlet of the coolant supply mechanism 13.1 via pipelines. The coolant supply mechanism 13.1 is connected to the control box 14. During the cutting process, the control box 14 controls the coolant in the coolant supply mechanism 13.1 to be sprayed through the nozzles 13.2 onto the cutting line and the workpiece 4 below, performing cooling and slag removal operations.

The details in the embodiments do not constitute a limitation on the scope of this utility model.
