Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a swing-type circular cutting device. Background Technology

[0002] Diamond wire cutting is an advanced process that uses a metal wire covered with diamond particles for efficient and precise cutting. Diamond particles are evenly distributed on the metal wire (such as high-carbon steel wire) to form a high-hardness, wear-resistant cutting tool. Then, through the high-speed unidirectional movement of the diamond wire, the diamond particles on the wire perform micro-grinding on the workpiece, achieving precise cutting. It has good cutting effect on difficult-to-cut materials such as ceramics, cemented carbide, and composite materials.

[0003] However, most existing diamond wire cutting equipment has a fixed contact area between the diamond wire and the material during the cutting process. For high-hardness and high-brittle materials, local stress concentration can easily lead to high cutting resistance, which not only reduces cutting efficiency but may also cause defects such as material chipping and cracking, affecting the processing quality. Utility Model Content

[0008] As a preferred embodiment of this utility model, the ring cutting assembly includes a drive wheel rotatably connected to the top of one side of the outer wall of the first drive plate and a tensioning wheel disposed at the top of one side of the outer wall of the second drive plate.

[0015] Example: Please refer to Figure 1 , Figure 2 and Figure 3 This utility model discloses a swing-cutting type circular wire cutting device, including a base 1. A gantry frame 2 is fixedly connected to one side of the upper surface of the base 1. Vertical moving components 3 are arranged on both sides of the gantry frame 2. The gantry frame 2 is connected to a first drive plate 4 and a second drive plate 5 of the two vertical moving components 3. The vertical moving components 3 include vertical drive motors 31 fixedly connected to both sides of the gantry frame 2. A vertical lead screw 32 is fixedly connected to the output end of the vertical drive motor 31. Vertical threaded sleeves 33 threaded to the two vertical lead screws 32 are fixedly connected to the outer walls of the first drive plate 4 and the second drive plate 5 respectively. Vertical slide rails 34 are fixedly connected to both sides of the outer walls of the gantry frame 2 near the vertical lead screws 32.

Vertical sliders 35 slidably connected to the vertical slide rails 34 are fixedly connected to the outer walls of the first drive plate 4 and the second drive plate 5 near the vertical slide rails 34. In use, the two vertical drive motors 31 can drive the two vertical lead screws 32 to rotate, which in turn can drive the first drive plate 4 and the second drive plate 5 to move along the two vertical lead screws 32 through the two vertical threaded sleeves 33 (the vertical slider 35 and the vertical slide rail 34 play a limiting role). The moving direction of the first drive plate 4 and the second drive plate 5 can be adjusted by adjusting the rotation direction of the output end of the vertical drive motor 31.

[0016] Reference Figure 1 , Figure 2 and Figure 3The first drive plate 4 and the second drive plate 5 are provided with a ring cutting assembly 7.

The ring cutting assembly 7 can support the diamond ring 6 and drive the diamond ring 6 to cut. The ring cutting assembly 7 includes a drive wheel 71 rotatably connected to the top of one side of the outer wall of the first drive plate 4 and a tensioning wheel 72 disposed at the top of one side of the outer wall of the second drive plate 5.

The diamond ring wire 6 sequentially passes through the drive wheel 71, the tensioning wheel 72 and the two driven wheels 73 to form a closed loop. A cutting drive motor 74 for driving the drive wheel 71 to rotate is fixedly connected to the first drive plate 4. When the cutting drive motor 74 is turned on, the drive wheel 71 will drive the diamond ring wire 6 to perform a closed loop motion around the drive wheel 71, the tensioning wheel 72 and the driven wheels 73. A tensioning assembly 75 for driving the tensioning wheel 72 to tension the diamond ring wire 6 is disposed on the second drive plate 5.

[0017] Reference Figure 2 , Figure 4 and Figure 5 The tensioning assembly 75 includes a tensioning bracket 751 and a tensioning servo motor 752 fixedly connected to the second drive plate 5. The tensioning wheel 72 is rotatably connected to the tensioning bracket 751. A tensioning threaded rod 753 is fixedly connected to the output end of the tensioning servo motor 752. A tensioning threaded sleeve 754 adapted to the tensioning threaded rod 753 is fixedly connected to the tensioning bracket 751. A tensioning groove 755 is provided on the second drive plate 5. A tensioning slider 756 adapted to the tensioning groove 755 is fixedly connected to the tensioning bracket 751. During use, the tension servo motor 752 drives the tension threaded rod 753 to rotate, which in turn drives the tension bracket 751 to move along the tension threaded rod 753 (at the same time, the tension slider 756 slides in the tension groove 755 to limit the tension bracket 751 and the tension threaded sleeve 754).

[0018] Reference Figure 1 , Figure 2 and Figure 3A horizontal moving component 8 is provided on the upper surface of the base 1. A support plate 9 is slidably connected to the base 1 through the horizontal moving component 8. The horizontal moving component 8 includes a horizontal drive motor 81 fixedly connected to one side of the upper surface of the base 1. A horizontal lead screw 82 is fixedly connected to the output end of the horizontal drive motor 81. A horizontal threaded sleeve 83 threaded to the horizontal lead screw 82 is fixedly connected to the center of the lower surface of the support plate 9. Horizontal slide rails 84 are fixedly connected to both sides of the horizontal lead screw 82 on the upper surface of the base 1. The horizontal slide rails 84 are parallel to the length direction of the horizontal lead screw 82. Horizontal sliders 85 are fixedly connected to both sides of the lower surface of the support plate 9 and slidably connected to the horizontal slide rails 84. The horizontal drive motor 81 can drive the horizontal lead screw 82 to rotate, thereby driving the horizontal threaded sleeve 83 and the support plate 9 to move along the horizontal lead screw 82. The upper surface of the support plate 9 is provided with a clamping assembly 10 for clamping materials. The clamping assembly 10 includes a rotating seat 101 fixedly connected to the center of the upper surface of the support plate 9. A pneumatic clamping fixture 102 is rotatably connected to one side of the rotating seat 101. A rotary drive motor 103 for driving the pneumatic clamping fixture 102 to rotate is fixedly connected to the side of the rotating seat 101 away from the pneumatic clamping fixture 102. When it is necessary to clamp materials, the materials can be placed in the pneumatic clamping fixture 102 for clamping. After the materials are clamped, the rotary drive motor 103 can drive the pneumatic clamping fixture 102 and the materials to rotate.

[0019] The working principle of this utility model is as follows: When in use, the operator first places the material to be cut in the clamping area of ​​the pneumatic clamping fixture 102, then closes the jaws of the pneumatic clamping fixture 102 to stably clamp the material. Then, the horizontal drive motor 81 drives the horizontal lead screw 82 to rotate. Through the threaded engagement of the horizontal threaded sleeve 83 and the horizontal lead screw 82, the bearing plate 9 moves along the horizontal slide rail 84 to the gantry 2 via the horizontal slider 85 until the part of the material to be cut is directly below the diamond ring 6. Once the material position is adjusted, the cutting drive motor 74 on the first drive plate 4 starts, driving the drive wheel 71 to rotate. The drive wheel 71 then drives the diamond ring 6 to perform a closed-loop motion around the drive wheel 71, tension wheel 72, and driven wheel 73. Then, the two vertical drive motors 31 first drive the two vertical lead screws 32 to rotate, and through the vertical threaded sleeve 33, drive the first drive plate 4 and the second drive plate 5 to move downwards. When they reach the preset position, the two vertical drive motors 31 drive the two vertical lead screws 32 to rotate alternately in opposite directions, thereby driving the first drive plate 4 and the second drive plate 5 to move up and down alternately to form a swinging motion. This reduces the contact area between the diamond ring 6 and the cutting part, thereby minimizing the cutting resistance of the diamond ring 6 to hard materials, improving the overall cutting efficiency of the device, and at the same time, minimizing cleavage fracture (edge ​​chipping) caused by cutting in one direction. Meanwhile, the rotary drive motor 103 can drive the pneumatic clamping fixture 102 and the material clamped by the pneumatic clamping fixture 102 to reciprocate and rotate in one direction, so that the cutting force direction of the diamond ring changes periodically, minimizing the occurrence of microcracks caused by local stress concentration, thereby further improving the processing quality of the material.
