Description

Technical Field

[0001] This utility model relates to the field of tensioning device technology, and more specifically, to a tensioning device for cutting green blanks. Background Technology

[0002] The samarium cobalt rare earth magnetic material green blank cutting device is used for cutting and processing samarium cobalt rare earth magnetic materials. Samarium cobalt rare earth magnetic material green blanks are generally cut using diamond wire cutting. The cutting principle of diamond wire cutting utilizes the grinding action of diamond particles on the material surface during high-speed rotation to achieve cutting. In existing technologies, diamond wires need to be replaced after a period of use to maintain their rigidity and tension, usually manually. The tension needs to be adjusted after replacement, and during the use of diamond wire, the prolonged reciprocating contact with the rare earth material alters its properties, causing a decrease in tension and affecting the rare earth cutting effect. Therefore, a tensioning device for green blank cutting is proposed. Utility Model Content

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] See Figures 1 to 6 This utility model provides a tensioning device for green blank cutting, suitable for installation in a rare earth green blank cutting device. It includes a drive roller 2, a driven roller 3, and an adjusting roller 4. The drive roller 2 is mounted on the green blank cutting frame 1 and is rotatably connected to the green blank cutting frame 1. Annular diamond cutting wires 5 are sleeved on the drive roller 2 and the driven roller 3. The driven roller 3 is provided with a first sliding connection component, which is mounted on a mounting panel 8. The first sliding connection component supports the driven roller 3 to move laterally on the green blank cutting frame 1, changing the contact state between the driven roller 3 and the annular diamond cutting wires 5. The adjusting roller 4 is provided with a second sliding connection component, which supports the adjusting roller 4 to move vertically on the green blank cutting frame 1, changing the contact state between the adjusting roller 4 and the annular diamond cutting wires 5.

[0028] The annular diamond cutting wire 5 is mounted on the active roller 2 and the driven roller 3. The active roller 2 rotates on the green cutting frame 1, driving the driven roller 3 to rotate at the same amplitude. This causes the annular diamond cutting wire 5 to come into contact with the rare earth green material through friction, thus achieving the cutting process. After the cutting device has been used for a period of time, the tension of the annular diamond cutting wire 5 may change due to the interaction force of the cutting and the changes in the structural properties of the annular diamond cutting wire 5 itself, making it difficult to guarantee the cutting effect on rare earth materials. The second sliding connection component can be used to drive the adjusting roller 4 to abut against the annular diamond cutting wire 5. During the use of the cutting device, the tension of the annular diamond cutting wire 5 can be finely adjusted based on the tension detection results. After the annular diamond cutting wire 5 is installed or becomes loose after long-term use, the first sliding connection component can be used to push the driven roller 3 to move laterally on the green cutting frame 1, changing the relative distance between the driven roller 3 and the active roller 2, which can achieve a larger range of tension adjustment for the annular diamond cutting wire 5.

[0029] The adjusting roller 4 provides real-time support and fine-tuning, adapting to real-time control of the cutting operation. The movement of the driven roller 3 will significantly adjust the annular length of the annular diamond cutting line 5, making it suitable for use in situations where phased adjustments or fine-tuning are difficult to control tension adjustment.

[0030] See Figure 4 and Figure 6The first sliding connection assembly includes a transverse sliding frame 81 and a first push fixing frame 82 connected to the first sliding connection assembly. The transverse sliding frame 81 is slidably connected to the transverse slider 33. The transverse slider 33 is provided with a first movable mounting seat 32. The first movable mounting seat 32 is provided with a driven shaft 31 in the center. The driven roller 3 is provided with a fastening plate 35 at one end near the first sliding connection assembly. The driven shaft 31 passes through the fastening plate 35 and is fixedly connected to the driven roller 3. The mounting panel 8 fixes the setting of the transverse sliding frame 81 and the first push fixing frame 82. The first sliding connection assembly uses the first push fixing frame 82 as a power support output device to control the transverse slider 33 to move laterally on the transverse sliding frame 81, change the transverse position relationship between the first movable mounting seat 32 and the first movable slot 11, and adjust the relative distance between the driven roller 3 and the driving roller 2 to adjust the tension of the annular diamond cutting wire 5.

[0031] The first movable mounting base 32 is rotatably connected to the driven shaft 31. That is, the driven shaft 31 is pulled by the tension of the annular diamond cutting wire 5 and rotates within the first movable mounting base 32, maintaining the rotatable connection between the driven shaft 31 and the first movable mounting base 32. While realizing the tension adjustment of the annular diamond cutting wire 5, it also ensures the normal rotational support of the driven roller 3.

[0032] The driven roller 3 enhances the firmness of its connection with the driven shaft 31 by setting a fastening plate 35, and establishes a contact with the green cutting frame 1 structure through the fastening plate 35, which can effectively prevent the rare earth powder cut off from entering the connection of the driven shaft 31 and ensure the normal operation of the driven rotating assembly.

[0033] The first push fixing frame 82 is fixedly connected to the output end of the first adjusting cylinder 34. The cylinder body of the first adjusting cylinder 34 is fixedly connected to the first movable mounting seat 32. The first sliding connection assembly is supported by the first push fixing frame 82 and fixedly connected to the output end of the first adjusting cylinder 34. When the first adjusting cylinder 34 receives the adjustment command, it controls the output end to change the output amount, thereby changing the distance between the cylinder body of the first adjusting cylinder 34 and the first push fixing frame 82. Since the first push fixing frame 82 is fixed, the cylinder body end of the first adjusting cylinder 34 pushes the first movable mounting seat 32 and the transverse slider 33 to move on the transverse sliding frame 81, changing the distance between the driven roller 3 and the driving roller 2.

[0034] The active roller 2 is connected to the rotating connecting seat 83 on the other side of the green cutting frame 1. The rotating connecting seat 83 is equipped with a motor mounting frame 84, and the motor mounting frame 84 is equipped with a servo motor 85. The servo motor 85 is used to control the rotation direction and rotation speed of the active roller 2 to realize the power output of the cutting operation.

[0035] The green cutting frame 1 is provided with a first movable slot 11 at the mounting position of the driven roller 3. The first movable slot 11 is a transverse slot, which facilitates the transverse displacement of the driven roller 3 within the first movable slot 11 under the control of the first sliding connection assembly.

[0036] See Figure 4 and Figure 5 The second sliding connection assembly includes a second push fixing frame 41, which is fixedly connected to the top edge of the green cutting frame 1 and to the output end of the second adjusting cylinder 42. The bottom of the cylinder body of the second adjusting cylinder 42 is provided with a second movable mounting seat 43, and an adjusting rotating shaft 44 is provided inside the second movable mounting seat 43. The adjusting rotating shaft 44 is fixedly connected to the adjusting roller 4. The second push fixing frame 41 is fixedly connected to the green cutting frame 1, thus establishing a fixed support for the output end of the second adjusting cylinder 42. That is, when the output of the second adjusting cylinder 42 is changed by the control signal, the position of the bottom cylinder body of the second adjusting cylinder 42 is actually changed, which drives the second movable mounting seat 43 to move vertically, thereby changing the specific position of the adjusting rotating shaft 44 on the green cutting frame 1 and changing the contact support position of the top position of the adjusting roller 4 on the annular diamond cutting wire 5, thereby realizing the fine adjustment of the tension of the annular diamond cutting wire 5.

[0037] The second movable mounting base 43 has two sets of vertical sliders 45 on the side near the green cutting frame 1. The green cutting frame 1 has a set of vertical sliding frames 46 corresponding to the vertical sliders 45. The vertical sliders 45 are sleeved on the vertical sliding frames 46. The two ends of the second movable mounting base 43 are connected to the vertical sliding frames 46 through the two sets of vertical sliders 45. Under the pushing and pulling action of the second adjusting cylinder 42, the second movable mounting base 43 moves vertically on the vertical sliding frames 46 through the vertical sliders 45, thereby controlling the vertical displacement of the adjusting roller 4 and changing the contact support node and support state between the adjusting roller 4 and the annular diamond cutting line 5.

[0038] The green cutting frame 1 is provided with a second movable slot 12 at the mounting position of the adjusting roller 4. The second movable slot 12 is set as a vertical slot, which facilitates the vertical displacement of the adjusting roller 4 within the second movable slot 12 under the control of the second sliding connection assembly.

[0039] The grooves of the driving roller 2 and the driven roller 3 are respectively set as lubricant grooves. The lubricant grooves are set as tiny annular grooves that can just accommodate the installation of the annular diamond cutting wire 5. The grooves of the driving roller 2 and the driven roller 3 provide a groove for the annular diamond cutting wire 5. The structure of the tiny annular grooves can limit the range of motion of the annular diamond cutting wire 5, prevent the annular diamond cutting wire 5 from being displaced, improve the accuracy of green cutting, and the grooves are set as solid grooves filled with lubricant. The lubricant can reduce the temperature generated during the high-speed rotation of the annular diamond cutting wire 5, reduce the wear of the wire and the groove, and extend the service life of the annular diamond cutting wire 5.

[0040] The green cutting frame 1 is equipped with a tension detection sensor 6. The detection end of the tension detection sensor 6 abuts against the annular diamond cutting wire 5. The tension detection sensor 6 detects the tension of the annular diamond cutting wire 5 and transmits the detection result to the control end. The control end adjusts the first sliding connection component and the second sliding connection component to change the position of the driven roller 3 and the adjusting roller 4, so as to adjust the tension of the annular diamond cutting wire 5.

[0041] The green cutting frame 1 is an irregularly shaped housing that fits the drive roller 2 and the driven roller 3. The middle section of the green cutting frame 1 has a notch, and the space of the notch is set as the green moving chamber 7. The outer end of the green cutting frame 1 is set with a housing to enclose the drive roller 2, the driven roller 3 and other components. The entire cutting assembly and tensioning assembly are controlled by electrical signals from the control terminal without manual intervention. The annular diamond cutting wire 5 runs at high speed through the notch of the green cutting frame 1. The green moving chamber 7 drives the rare earth green blank to move in all directions within the notch, which facilitates the cutting of the green blank by the annular diamond cutting wire 5.

[0042] Below the green embryo moving chamber 7 is a cutting table 9, which includes a cutting platform and a three-dimensional moving device. It can control the cutting platform to achieve lifting, forward and backward displacement parallel to the annular diamond cutting line 5, and planar rotation, which facilitates three-dimensional cutting control of rare earth green embryos.

[0043] This utility model provides a tensioning device for green blank cutting parts. A first sliding connection assembly and a second sliding connection assembly are provided on the green blank cutting part to adjust the specific positions of the driven roller 3 and the adjusting roller 4, respectively, to adjust the tension of the annular diamond cutting wire 5. The driven roller 3 has a longer contact length with the annular diamond cutting wire 5, and its lateral adjustment can provide a larger range of tension adjustment for the annular diamond cutting wire 5. It is generally used during the installation and debugging of the annular diamond cutting wire 5. The adjusting roller 4 only makes point contact with the annular diamond cutting wire 5, and changing the position of the adjusting roller 4 can provide a slight tension adjustment for the annular diamond cutting wire 5. It is used during the operation of the annular diamond cutting wire 5, thereby ensuring the stability and practicality of tension adjustment during the installation and use of the annular diamond cutting wire 5.

[0044] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
