The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0022] In the field of materials processing, band saws are a common cutting tool, widely favored for their ease of operation and adaptability. However, certain industries have specific requirements for the cutting accuracy and direction of sheet metal. Although band saws excel in cutting efficiency and flexibility, improving the cutting accuracy of these devices in practical applications has become a pressing issue in this field.

[0023] Therefore, this application provides a band saw cutting device to solve the problem of low cutting accuracy in band saw cutting devices.

[0024] Please see Figure 1 and Figure 2 This is a schematic diagram of the structure of a band saw cutting device according to an embodiment of this application. In this embodiment, the band saw cutting device includes a support frame, a cutting device body, and a measuring unit.

[0025] The support frame includes a column S2 and a saw beam S3, an operating platform S4, and a base S1 arranged sequentially along the X-direction on the end face of the column S2. The operating platform S4 is supported on the base S1. The saw beam S3 and the base S1 are connected to the column S2. Specifically, the column S2 is located on the left side of the base S1, the saw beam S3 is located above the right end of the column S2, the base S1 and the saw beam S3 are arranged parallel to each other on the first side wall of the column S2, the contact surfaces of the base S1 and the column S2 are connected, the contact surfaces of the saw beam S3 and the column S2 are connected, and the operating platform S4 is located on the top of the base S1 to form a first receiving space.

[0026] Please refer to the following: Figure 3The main body of the cutting device includes a transmission device S8 mounted on the operating platform S4, a drive wheel S7 driven by the transmission device S8, and a driven wheel S6 connected to the drive wheel S7 via a saw blade S5. Specifically, the two ends of the driven shaft 4 of the driven wheel S6 are fixed to the second and third side walls of the saw beam S3, respectively, so that the driven wheel S6 is housed in a second receiving space within the saw beam S3. The second side wall is parallel to the third side wall. The output shaft of the transmission device S8 is connected to the drive wheel S7, and the transmission device S8 is fixed to the surface of the operating platform S4 near the base S1, so that the drive wheel S7 is housed in a first receiving space. The bottom of the saw beam S3 is provided with a first saw blade channel parallel to the slide rod 32, and the operating platform S4 is provided with a second saw blade channel. The saw blade S5 is tensioned on the drive wheel S7 and the driven wheel S6 through the first and second saw blade channels. Specifically, one side of the saw blade S5 extends along the X-axis through the first saw blade channel and the second saw blade channel, and the other side of the saw blade S5 is housed in the third housing space in the column S2 along the X-axis, so that the saw blade S5 is tensioned on the driving wheel S7 and the driven wheel S6.

[0027] The measuring unit includes an angle gauge 19 and a limiting plate 26. A slide rail 31 is provided on the operating platform S4. The slide rod 32 of the angle gauge 19 is disposed within the slide rail 31. The angle gauge 19 abuts against the material being cut via the limiting plate 26. In practical applications, users can adjust the cutting angle of the material being cut by moving the slide rod 32 to adjust the position of the angle gauge 19 or by rotating the angle gauge 19, thereby improving the cutting accuracy of the material. Furthermore, the limiting plate 26 ensures that the material being cut is securely abutted against the angle gauge 19, further enhancing the safety and reliability of the cutting device.

[0028] Specifically, the angle ruler 19 includes a pointer 193 and an angle ruler 191. The angle ruler 191 has angle markings on its curved edge, and a groove 192 parallel to the curved edge is provided on its surface. A slider 195 corresponding to the groove 192 is provided on the slide rod 32, and the slider 195 is engaged in the groove 192. The bottom of the angle ruler 191 abuts against one side of the limiting plate 26. Specifically, the bottom of the angle ruler 191 can be connected to one side of the limiting plate 26 via a connector 196. The pointer 193's needle points to the angle markings on the curved edge of the angle ruler 191. The pointer 193's needle body has a through hole 194, and the slide rod 32 has a corresponding screw hole. In practical applications, a screw can be used to fix the pointer 193 to the slide rod 32 through the through hole 194. Specifically, when the material to be cut is pressed against the other side of the limiting plate 26, the user can change the cutting angle of the material by rotating the slider 195 in the slot 192.

[0029] In practical applications, the central axis of the driven wheel S6 and the central axis of the driving wheel S7 are located in the same plane, and the driving wheel S7 and the transmission device S8 are located on the same central axis. When the band saw cutting device is working, the transmission device S8 can drive the driving wheel S7 to rotate through the output shaft, and then drive the driven wheel S6 and the saw blade S5 to rotate through the driving wheel S7 to cut the material being cut, thereby improving the cutting accuracy of the band saw cutting device.

[0030] In one alternative implementation, please refer to Figure 4 and Figure 5 The saw beam S3 includes a first housing 8 and a second housing 1. The receiving opening of the first housing 8 connects to the receiving opening of the second housing 1 to form a second receiving space, and the connecting portion 81 of the first housing 8 and the connecting portion 82 of the second housing 1 are both connected to the first side wall of the column S2. Specifically, the first housing 8 of the saw beam S3 is provided with a second side wall 83, and the second housing 1 of the saw beam S3 is provided with a third side wall 84, the second side wall 83 and the third side wall 84 being parallel to each other.

[0031] In an optional implementation, the band saw cutting device further includes a first bearing 2 and a second bearing 7. The wheel body 5 of the driven wheel S6 is connected to the driven shaft 4 via a positioning ring 3, so that the driven shaft 4 can stably drive the wheel body 5 to rotate. One end of the driven shaft 4 is fixed to the second side wall 83 of the saw beam S3 via the first bearing 2, that is, one end of the driven shaft 4 is fixed to the second side wall 83 via the first bearing 2. The other end of the driven shaft 4 is fixed to the third side wall 84 of the saw beam S3 via the second bearing 7, that is, the other end of the driven shaft 4 is fixed to the third side wall 84 via the second bearing 7. When the driven wheel S6 rotates, the driving wheel S7 drives the wheel body 5 of the driven wheel S6 to rotate via the saw blade S5, and then drives the driven shaft 4 to rotate within the first bearing 2 and the second bearing 7 via the wheel body 5, which improves the stability of the driven wheel S6 and thus improves the cutting accuracy of the band saw cutting device.

[0032] In an optional implementation, the transmission device S8 includes a motor 11 and a first bracket 13. The output shaft of the motor 11 is connected to the drive wheel S7. Along the X-axis, the first bracket 13 is fixed to the bottom surface of the operating platform S4 by screws 28, thereby fixing the motor 11 and the drive wheel S7 within the first receiving space in the operating platform S4 and the base S1. In practical applications, a brushless external rotor motor can be used as the motor 11 to reduce noise during the operation of the band saw cutting device and achieve the corresponding driving function.

[0033] In an optional implementation, the transmission device S8 further includes a housing 10, a third bearing 24, and a fourth bearing 25. In practical applications, along the opposite direction of the Y-axis, the housing 10 fixes the motor 11 to the first bracket 13 with screws 27, so that the motor 11 is housed in the fourth receiving space between the housing 10 and the first bracket 13. The output shaft of the motor 11 can be connected to the drive wheel S7 through the through hole on the housing 10 and the shaft retaining ring 15 in sequence. This can prevent the motor 11 from shaking and affecting the cutting accuracy of the band saw cutting device. The third bearing 24 is fixed to the surface of the first bracket 13 near the housing 10. One end of the output shaft of the motor 11 is connected to the drive wheel S7 through the third bearing 24 and the through hole on the first bracket 13 in sequence. The fourth bearing 25 is fixed to the bottom of the housing 10, and the other end of the output shaft of the motor 11 is fixed to the bottom of the housing 10 through the fourth bearing 25. The bottom of the housing 10 is on the side wall of the housing 10 away from the first bracket 13. In this embodiment, the output shaft of the motor 11 is fixed inside the third bearing 24 and the fourth bearing 25 to prevent the output shaft of the motor 11 from shaking and affecting the cutting accuracy of the band saw cutting device, thereby improving the safety and reliability of the band saw cutting device.

[0034] In an alternative implementation, the band saw cutting device also includes a control board 18, a switch 21, and a battery pack S9.

[0035] In this embodiment, the control board 18 can be fixed to the bottom surface of the base S1 by screws 30 in the opposite direction of the X-axis, so as to house the control board 18 within the first receiving space. The control board 18 is connected to the control terminal of the transmission device S8 via a wiring harness, and is also connected to the battery pack S9 and the switch 21 via a wiring harness. The battery pack S9 and the switch 21 are located on the side of the base S1, which is the exterior of the side wall adjacent to the operating platform S4 and the column S2. In practical applications, the battery pack S9 is used to provide operating voltage to the control board 18, and the control board 18 provides operating voltage to the motor 11, so as to drive the motor 11 to work through the control board 18. The user can control the working status of the band saw cutting device through the switch 21.

[0036] In an optional implementation, the battery pack S9 includes a second bracket 22, a fixing member, and at least two battery packs 23. In this embodiment, the battery packs 23 are snapped into snap-fit ​​slots on the second bracket 22. Specifically, two snap-fit ​​positions for the battery packs 23 are provided on both sides of the second bracket 22 in the Z-axis direction. The second bracket 22 is fixed to the side of the base S1 by the fixing member. In practical applications, the fixing member can be... Figure 3The fixed frame shown in the figure has a corresponding limiting part on the battery pack 23. The battery pack 23 can be fixed in the snap-fit ​​grooves on both sides of the second bracket 22 by screws 29, so that when the band saw cutting device is working, it can directly power the control board 18 and the motor 11 through the battery pack 23 without connecting to the power socket, which improves the flexibility and endurance of the band saw cutting device.

[0037] In practical applications, the band saw cutting device also includes a shaft retaining ring 15. The drive wheel S7 is connected to the output shaft of the transmission device S8 through the shaft retaining ring 15, so that the drive wheel S7 can be stably connected to the output shaft of the transmission device S8 through the shaft retaining ring 15, and the shaking of the drive wheel S7 will not affect the cutting accuracy of the band saw cutting device.

[0038] In an optional implementation, the control board 18 has a package box 181 and a circuit board 182 housed within the package box 181. A controller (not shown) is mounted on the circuit board 182. The battery pack S9 and the switch 21 are electrically connected to the controller on the circuit board 182 via wiring. The controller on the circuit board 182 is connected to the control terminal of the transmission device S8 via the circuit board 182 and wiring, allowing the user to control the switch 21 to output a start signal to the controller. When the controller receives the operating voltage output from the battery pack S9, it can drive the motor 11 to operate, thereby driving the drive wheel S7 to rotate. The drive wheel S7 then drives the driven wheel S6 and the saw blade C5 to rotate and cut the material being cut. In practical applications, the package box 181 can be fixed to the bottom surface of the base S1 using screws 30 in the opposite direction of the X-axis. Furthermore, the above-mentioned band saw cutting device can be used to cut wood, foam board, acrylic board, or plastic board, and its practical applications are not limited to these materials.

[0039] In this embodiment, a cutting device is composed of a transmission device S8, a drive wheel S7 driven by the transmission device S8, and a driven wheel S6 connected to the drive wheel S7 via a saw blade S5. The driven wheel S6 is fixed inside the saw beam S3 by bearings, and the drive wheel S7 is fixed to the operating platform S4 by the transmission device S8 to prevent wheel wobbling from affecting the cutting accuracy of the saw blade S5. A slide rail 31 is installed on the operating platform S4 so that the slide rod 32 of the angle guide 19 can be embedded therein. At the same time, the limiting plate 26 is used to press the material to be cut tightly against the angle guide 19, allowing the user to flexibly set the cutting angle and position of the material to be cut by rotating the angle guide 19 or adjusting the position of the slide rod 32 on the slide rail 31, thereby achieving curved cutting and improving the cutting accuracy of the bench band saw.

[0040] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application should fall within the scope of protection claimed by this application.
