Description
Technical Field
[0001] This utility model relates to the field of band saw technology, specifically to a band saw with an adjustable cutting angle. Background Technology
[0002] Band saws are commonly used cutting equipment in many fields such as metal processing and wood processing. However, existing band saws have certain limitations in terms of cutting angle adjustment.
[0003] For example, most traditional band saws can only achieve vertical cutting or cutting at a limited number of preset angles. When faced with complex workpiece cutting needs, they are unable to meet diverse angle requirements. When cutting parts with special angle requirements, such as some irregularly shaped structural parts in the aerospace field or special shaped materials in the building decoration industry, traditional band saws cannot directly complete the cutting. They often require manual adjustment of the workpiece position, which is not only inefficient but also makes it difficult to guarantee cutting accuracy, easily leading to a large number of scraps. In addition, the operation process of switching cutting angles on existing band saws is relatively cumbersome, requiring professional technicians to spend a long time debugging and calibration, which seriously affects production efficiency. Summary of the Invention
[0004] In view of the problems existing in the above-mentioned band saws, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a band saw with an adjustable cutting angle, which solves the problems of inconvenient cutting angle adjustment, inability to meet diverse angle requirements, and cumbersome operation of existing band saws.
[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustable-angle band saw includes a base, a support fixedly mounted on the top of the base, a crossbeam rotatably mounted between the supports, a first electric cylinder fixedly mounted on the bottom of the crossbeam, a saw blade frame fixedly mounted on the moving end of the first electric cylinder, a saw blade body rotatably mounted inside the saw blade frame, a first motor fixedly mounted on one side of the saw blade frame, the output end of the first motor being fixedly connected to the saw blade body, a support frame fixedly mounted on one side of the support, an adjusting rod threaded onto one side of the support frame, one end of the adjusting rod being rotatably connected to the crossbeam, and a clamping device fixedly mounted on the top of the base.
[0007] Preferably, the clamping device includes a second motor and a lead screw. The second motor is fixedly mounted on one side of the base, and the lead screw is fixedly mounted on the output end of the second motor. A clamping plate is threaded onto the wall of the lead screw, and a fixing plate is fixedly mounted on the top of the base.
[0008] Preferably, a sliding groove is fixedly provided on one side of the bracket, a slider is slidably provided in the sliding groove, a protective plate is fixedly provided on one side of the slider, two pins are slidably provided on one side of the protective plate, and a plug-in groove is fixedly provided in the sliding groove, with the pins and plug-in grooves engaging.
[0009] Preferably, a control panel is fixedly mounted on one side of the bracket, a display screen is fixedly mounted on the top of the control panel, and a wireless transmission module is fixedly mounted on one side of the display screen.
[0010] Furthermore, a shock-absorbing pad is fixedly provided at the bottom of the base.
[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model utilizes a crossbeam rotatably mounted between supports, which engages with a threaded adjusting rod on the support frame. Rotating the adjusting rod drives the crossbeam to rotate around the supports, thereby adjusting the cutting angle of the saw blade. Compared to the limitations of traditional band saws, which can only achieve vertical or limited preset angle cutting, this structure can flexibly adapt to diverse angle cutting needs such as aerospace irregular-shaped parts and special-shaped building decoration materials, eliminating the need for manual adjustment of the workpiece position and significantly improving cutting adaptability.
[0012] 2. This utility model employs a first electric cylinder to drive the saw blade frame for stable feeding, which, combined with a first motor, directly drives the saw blade body to rotate, ensuring stability during the cutting process. Simultaneously, the crossbeam angle adjustment is precisely controlled via a threaded structure, reducing manual adjustment errors and lowering the scrap rate. Angle switching eliminates the need for complex calibration procedures, shortening preparation time and effectively improving production efficiency.
[0013] 3. In this utility model, the clamping device uses a second motor to drive the lead screw to rotate, causing the clamping plate to engage with the fixing plate to clamp the workpiece. Compared with manual fixing, the mechanized clamping method is more convenient and labor-saving, and the clamping force is uniform and controllable, avoiding accuracy deviations caused by workpiece displacement during cutting and further ensuring cutting quality.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0020] This utility model discloses a band saw with an adjustable cutting angle.
[0021] This utility model provides, for example Figure 1-3The band saw with adjustable cutting angle shown includes a base 1, a support 2 fixedly mounted on the top of the base 1, a crossbeam 3 rotatably mounted between the support 2, a first electric cylinder 4 fixedly mounted at the bottom of the crossbeam 3, a saw blade frame 5 fixedly mounted at the moving end of the first electric cylinder 4, a saw blade body 6 rotatably mounted inside the saw blade frame 5, a first motor 7 fixedly mounted on one side of the saw blade frame 5, the output end of the first motor 7 being fixedly connected to the saw blade body 6, a support frame 8 fixedly mounted on one side of the support 2, an adjusting rod 9 threaded onto one side of the support frame 8, one end of the adjusting rod 9 being rotatably connected to the crossbeam 3, and a clamping device fixedly mounted on the top of the base 1. This band saw with adjustable cutting angle achieves core functions such as flexible adjustment of cutting angle, stable workpiece clamping, and efficient and precise cutting through the coordinated operation of its mechanical structure and electrical control system. Its overall working principle revolves around five core systems: angle adjustment, power transmission, workpiece fixation, safety protection, and intelligent monitoring. These systems work together to complete the entire process from parameter setting to cutting completion. Regarding basic support and vibration damping, the base 1 serves as the load-bearing foundation of the entire equipment. The vibration damping pads 20 fixed at the bottom achieve a dual function: firstly, they provide a stable mounting platform for all components above, ensuring structural stability; secondly, the damping pads 20 absorb the vibration energy generated during cutting, reducing bumps and noise during operation and preventing saw blade misalignment or workpiece displacement caused by vibration, thus providing the foundation for high-precision cutting. The bracket 2 is vertically fixed to the top of the base 1, not only supporting the crossbeam 3 but also providing support for the angle adjustment mechanism and preventing... The protective device and control system provide the mounting carrier, forming the overall frame structure of the equipment. The angle adjustment system is the core functional module of this band saw. Its operating principle is based on the synergy of mechanical transmission and structural support. The crossbeam 3 is installed between the supports 2 via a rotating structure and can rotate freely around the connecting shaft, thereby changing the cutting angle of the saw blade. The support frame 8 is fixed to one side of the support 2, and its threaded hole cooperates with the adjusting rod 9 to form a threaded transmission mechanism. When the cutting angle needs to be adjusted, the operator rotates the adjusting rod 9. Since the adjusting rod 9 and the support frame 8 are connected by threads, the rotational motion is converted into axial displacement. One end of the adjusting rod 9 pushes the crossbeam 3 to rotate around the support 2 until the saw blade reaches the preset angle. This threaded transmission structure has a self-locking characteristic, and there is no locking after the angle adjustment is completed. An additional fixing device is needed to maintain the current angle, ensuring its stability during cutting. The saw blade drive and feed system provides cutting power and controls the cutting depth. The saw blade body 6 is installed inside the saw blade holder 5 and achieves cyclic movement via a rotating shaft. A first motor 7 fixed on one side of the saw blade holder 5 provides driving force to the saw blade. The motor output is directly connected to the drive shaft of the saw blade body 6. When the motor starts, the output torque is transmitted to the saw blade through the shaft, driving the saw blade to cyclically move at high speed. The cutting action is achieved by the friction between the saw teeth and the workpiece. The top of the saw blade holder 5 is connected to the moving end of the first electric cylinder 4. The cylinder body is fixed to the bottom of the crossbeam 3. When cutting feed is required, the control system controls the extension and retraction of the first electric cylinder 4. The piston rod of the electric cylinder pushes the saw blade holder 5 to move vertically.The saw blade cuts into and feeds the workpiece. The feed speed of the electric cylinder can be precisely adjusted via the control panel 17 to adapt to the cutting needs of workpieces of different materials, avoiding damage to the saw blade due to excessive feed or affecting efficiency due to excessive feed. The workpiece clamping system achieves stable fixation of the workpiece through mechanization, preventing workpiece movement during cutting and affecting accuracy. The clamping device consists of a second motor 10, a lead screw 11, a clamping plate 12, and a fixing plate 13. The fixing plate 13 is fixed to the top of the base 1 as a clamping reference. The lead screw 11 is installed inside the base 1 through bearings, with one end connected to the output end of the second motor 10 and the other end engaging with the threaded hole at the bottom of the clamping plate 12. After the workpiece is placed, the operator starts the second motor 10 via the control panel 17, and the motor drives the lead screw... When rod 11 rotates, due to the threaded engagement between lead screw 11 and clamping plate 12, the rotational motion is converted into horizontal displacement of clamping plate 12. Clamping plate 12 moves towards fixed plate 13 until it engages with fixed plate 13 to clamp the workpiece. Lead screw 11 transmission features smooth transmission and uniform clamping force. The position of clamping plate 12 can be precisely controlled by forward and reverse rotation of the motor according to the workpiece size, adapting to the fixing requirements of workpieces of different specifications. The safety protection system ensures the safety of operators through an adjustable protective structure. The slide groove 14 on one side of bracket 2 provides a sliding track for slider 15. Protective plate 21 is fixed to one side of slider 15 and can move up and down along slide groove 14 with slider 15 to achieve adjustment of protective height. The pin 16 on one side of protective plate 21 engages with the insertion groove 2 in slide groove 14. 2. After the protective plate 21 is adjusted to the appropriate height, insert the pin 16 to make it fit tightly with the insertion slot 22, thus fixing the position of the protective plate 21. During the cutting process, the protective plate 21 is located between the saw blade and the operator, which can effectively block the flying debris, sparks and other flying objects generated during cutting, avoiding injury to the operator, while not affecting the observation of the cutting process. The intelligent control and monitoring system realizes convenient operation and status tracking of the equipment. The control panel 17 on one side of the bracket 2 integrates various control buttons and parameter setting interfaces. The operator inputs parameters such as cutting angle, feed speed and clamping force through the panel. The instructions are transmitted to the control modules of each motor and electric cylinder through the internal circuit to realize the automated operation of the equipment. The display screen 18 displays the current cutting status in real time. Key parameters such as angle, saw blade speed, and feed depth facilitate operator monitoring of equipment operation. The wireless transmission module 19 on one side of the display screen 18 uploads equipment operation data to a remote monitoring system in real time, enabling digital management of the production process and supporting remote fault diagnosis to improve equipment maintenance efficiency. In the overall workflow, all systems work together: after startup, the shock-absorbing pad 20 reduces equipment vibration; the angle of the crossbeam 3 is adjusted using the adjusting rod 9 to determine the cutting direction; the clamping device clamps the workpiece; the height of the protective plate 21 is adjusted and fixed; the first motor 7 is started to rotate the saw blade; and the first electric cylinder 4 drives the saw blade feed to complete the cutting. During the process, the display screen 18 shows parameters in real time, and the wireless transmission module 19 uploads data. After cutting is completed...Each component resets under the control of the operating system, awaiting the next operation. This multi-system collaborative working principle ensures that the equipment combines angle adjustment flexibility, cutting accuracy stability, and operational safety, meeting the needs of diverse cutting scenarios. For easier clamping, such as Figure 1 As shown, the clamping device includes a second motor 10 and a lead screw 11. The second motor 10 is fixedly installed on one side of the base 1, and the lead screw 11 is fixedly installed at the output end of the second motor 10. A clamping plate 12 is threaded on the wall of the lead screw 11, and a fixing plate 13 is fixedly installed on the top of the base 1.
[0022] For the sake of convenient protection, such as Figure 2 As shown, a slide groove 14 is fixedly provided on one side of the bracket 2, a slider 15 is slidably provided in the slide groove 14, a protective plate 21 is fixedly provided on one side of the slider 15, two pins 16 are slidably provided on one side of the protective plate 21, and a plug groove 22 is fixedly provided in the slide groove 14, and the pins 16 are plugged into the plug groove 22.
[0023] For ease of operation, such as Figure 1-3 As shown, a control panel 17 is fixedly mounted on one side of the bracket 2, a display screen 18 is fixedly mounted on the top of the control panel 17, and a wireless transmission module 19 is fixedly mounted on one side of the display screen 18.
[0024] Finally, for better shock absorption, such as Figure 1 As shown, a shock-absorbing pad 20 is fixedly installed at the bottom of the base 1.
