A kind of anti-wear automatic deviation correction device of bimetallic band saw blade

Abstract

This utility model relates to the field of saw blades and discloses an automatic anti-wear correction device for bimetal band saw blades. It mainly includes a sawing machine, a support frame, a correction mechanism, a saw blade fixing mechanism, and a sensing and monitoring system. The correction mechanism consists of two sets of orthogonally arranged correction components, each driven by a motor-driven lead screw to move a sliding seat along mutually perpendicular guide tracks, thereby achieving two-dimensional position adjustment of the bimetal band saw blade in a plane. The saw blade fixing mechanism uses a hydraulic drive with connecting rods to drive a fixing block equipped with rubber pads to center and clamp the saw blade, ensuring reliable clamping and effectively preventing wear on the saw blade surface. Non-contact sensors installed on the support frame monitor the longitudinal and lateral position deviations of the saw blade in real time and feed them back to the control system, triggering the automatic action of the correction mechanism to promptly correct saw blade deviation. This utility model achieves real-time monitoring and automatic precise correction of the bimetal band saw blade position during sawing, significantly improving sawing stability.

Description

Technical Field

[0001] This utility model relates to the field of saw blades, specifically to an anti-wear automatic correction device for bimetallic band saw blades. Background Technology

[0002] In the metal processing industry, bimetal band saw blades are widely used for cutting various metal materials due to their high strength and high toughness. However, during long-term high-speed operation, the saw blade is prone to lateral or longitudinal deviation due to factors such as saw vibration, uneven material resistance, and changes in the saw blade's own tension. At the same time, friction between the saw blade and fixed parts will also accelerate its wear. These problems not only affect the cutting accuracy but also shorten the saw blade's service life and increase production costs. Therefore, in order to ensure the stability of sawing operations, improve processing quality, and reduce wear, there is an urgent need for devices that combine anti-wear and automatic deviation correction functions to assist the operation of bimetal band saw blades.

[0003] Traditional band saw blade correction relies heavily on manual observation and adjustment based on experience, resulting in slow response and limited accuracy. This makes it difficult to meet the demands of high-speed, high-precision modern machining. Some mechanical correction mechanisms lack effective real-time monitoring and feedback mechanisms, failing to quickly compensate for minor blade deviations. This leads to unstable sawing accuracy, increased scrap rate, and exacerbates abnormal wear on the saw blade, increasing production costs and equipment maintenance frequency. To address these issues, we propose an anti-wear automatic correction device for bimetallic band saw blades. Summary of the Invention

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 An anti-wear automatic correction device for bimetallic band saw blades includes a sawing machine 1 and a support frame 12. Support plates are symmetrically fixedly installed on both sides of the upper surface of the sawing machine 1. The support frame 12 is fixedly installed on the upper surface of the sawing machine 1 in the middle of the two support plates. The support frame 12 is formed by four support columns and a support top plate. On the two supporting vertical plates of the sawing machine 1, a correction mechanism is symmetrically fixed on their opposite surfaces. The correction mechanism includes a correction component one and a correction component two. The correction component one is set on the two supporting vertical plates of the sawing machine 1, and the correction component two is set on the correction component one. The second correction component is equipped with a connecting plate 6, and the connecting plate 6 is provided with a saw blade fixing mechanism, which includes a transmission component and a fixing component. A bimetal band saw blade 2 is installed between the two fixed components on both sides.

[0023] Furthermore, the first correction component includes a fixed base 15, a motor 16, and a lead screw 18. Fixed bases 15 are fixedly installed on the opposite surfaces of the two support plates on the sawing machine 1. Sliding strips are symmetrically fixedly installed on the two side walls of the fixed base 15. Vertical plates are symmetrically fixedly installed between the sliding strips on the two sides of the fixed base 15. A motor 16 is fixedly installed on one side wall of one of the vertical plates. A lead screw 18 is rotatably connected between the two vertical plates. The output shaft of the motor 16 and the lead screw 18 are coaxially fixedly connected. In addition to providing sliding support for the second sliding base 19, the sliding strips symmetrically fixed on the two side walls of the fixed base 15 can guide and limit the movement of the second sliding base 19, preventing the second sliding base 19 from shifting laterally during the transmission with the lead screw 18, and ensuring that the second sliding base 19 always moves along the preset trajectory.

[0024] Furthermore, the second correction component includes a sliding seat 17 and a sliding seat 2 19. The bottom surface of the sliding seat 2 19 is symmetrically provided with sliding grooves. A connecting plate is installed between the sliding grooves on both sides of the bottom surface of the sliding seat 2 19. The connecting plate is provided with threaded holes. Sliding strips are symmetrically fixedly installed on both sides of the upper plane of the sliding seat 2 19. Vertical plates are symmetrically fixedly installed between the sliding strips on both sides of the plane of the sliding seat 2 19. Another motor 16 is fixedly installed on one side wall of one of the vertical plates. Another lead screw 18 is rotatably connected between the two vertical plates. The output shaft of the motor 16 and the lead screw 18 are coaxially fixedly connected. The bottom surface of the sliding seat 17 is symmetrically provided with sliding grooves, and a connecting plate is installed between the sliding grooves on both sides of the bottom surface of the sliding seat 17. The connecting plate is provided with threaded holes.

[0025] Furthermore, the sliding groove at the bottom of the sliding seat 19 is slidably connected to the sliding bar on the fixed seat 15, and the lead screw 18 on the fixed seat 15 is threadedly connected to the threaded hole at the bottom of the sliding seat 19. The sliding groove at the bottom of sliding seat 17 is slidably connected to the sliding bar on sliding seat 2 19, and the lead screw 18 on sliding seat 2 19 is threadedly connected to the threaded hole at the bottom of sliding seat 17.

[0026] Furthermore, the sliding bar on the fixed seat 15 and the sliding bar on the second sliding seat 19 are perpendicularly aligned. This arrangement makes the moving direction of the second sliding seat 19 orthogonal to the moving direction of the first sliding seat 17. When the saw blade deviates laterally and longitudinally at the same time, the correction mechanism can control the second sliding seat 19 and the first sliding seat 17 to move in the vertical direction respectively to achieve compound correction of the saw blade deviation. No step-by-step adjustment is required, which greatly improves the correction efficiency. At the same time, the vertical layout also makes the structure of the entire correction mechanism more compact, reduces the space occupied by other components on the saw machine 1, and optimizes the overall structural layout of the device.

[0027] Furthermore, a connecting plate 6 is fixedly connected to the plane of the sliding seat 17 opposite to the sliding seat 2 19; The transmission assembly includes a support base 5, a hydraulic cylinder 9, a piston rod 10, and a connecting rod 11. A slide bar is fixedly installed in the middle of the bottom surface of the support base 5. Support connecting columns are symmetrically fixedly installed on both sides of the bottom surface of the support base 5 corresponding to the slide bar. The support connecting columns and the connecting plate 6 are fixedly connected to the plane opposite to the sliding seat 17. A hydraulic cylinder 9 is fixedly installed on the bottom surface of the support base 5 near one of the side walls. A piston rod 10 is connected to the hydraulic cylinder 9. A connecting block is fixedly installed on the end of the piston rod 10 away from the hydraulic cylinder 9. A hinge shaft is symmetrically fixedly installed on the connecting block. Connecting rods 11 are hinged to the two hinge shafts respectively. Limiting plates are fixedly installed on the upper surface of the support base 5 near the four corners, and limiting holes are opened on the limiting plates.

[0028] Furthermore, the fixing component includes a fixing block 3, a sliding block 4, and a guide rod 7. The sliding block 4 is L-shaped, and a groove is provided on one of the plates of the sliding block 4. The fixing block 3 is fixedly installed on the other plate of the sliding block 4. The guide rod 7 is symmetrically fixedly installed on the side of the fixing block 3 facing the sliding block 4. A hinge shaft is fixedly installed on the bottom surface of the sliding block 4.

[0029] Furthermore, the sliding groove on the sliding block 4 and the sliding strip on the support base 5 are slidably connected, and the other end of the connecting rod 11 is hinged to the hinge shaft on the sliding block 4. The guide rod 7 and the limiting hole on the support base 5 are slidably connected coaxially. Rubber strips 8 are fixedly installed on the opposite surfaces of the two fixing blocks 3.

[0030] Furthermore, a sensor 13 is fixedly installed on the bottom surface of the support frame 12 corresponding to the top of the bimetal band saw blade 2; Sensor 14 is fixedly mounted on the opposite surfaces of the support columns on the support frame 12. Sensors 13 and 14 are D8251 eddy current sensors. This type of sensor has the characteristics of non-contact measurement, which can complete position monitoring without direct contact with the bimetal band saw blade 2, avoiding friction between the sensor and the saw blade that causes saw blade wear or sensor damage. At the same time, the D8251 eddy current sensor has a fast response speed and high measurement accuracy, which can quickly capture the slight position changes of the saw blade and send the correction signal to the motor 16 in a timely manner. This avoids the saw blade offset from increasing due to sensor response lag, and ensures that the correction action can be started in time before the saw blade offset affects the processing accuracy.

[0031] Structural Description: Sawing machine 1: Sawing machine 1 is the basic load-bearing component of the device, providing an installation platform for the whole. Symmetrical support plates are fixed on both sides of its surface to install the correction mechanism, and a support frame 12 is fixed in the middle to support the sawing operation of the bimetal band saw blade 2. It is the assembly basis for each functional component and ensures the overall structural stability of the device. Bimetal band saw blade 2: The bimetal band saw blade 2 is the core sawing component, installed between the two fixed components. It achieves metal material cutting with its high strength and high toughness. The anti-wear and automatic correction functions of the device are designed around it to reduce its wear and ensure sawing accuracy. Fixed block 3: Fixed block 3 is the core component for fixing the saw blade. It is connected to sliding block 4 and has a rubber strip 8 on its opposite side. The bimetal band saw blade 2 is clamped and fixed by the movement of sliding block 4. The rubber strip 8 avoids rigid contact and wear on the saw blade, and at the same time ensures that the saw blade does not loosen during sawing. Sliding block 4: Sliding block 4 is L-shaped and is the component connecting the transmission and fixing. One side plate has a sliding groove that cooperates with the sliding strip of the support base 5, and the other plate is equipped with fixing block 3. The bottom surface is hinged to the connecting rod 11. Driven by the connecting rod 11, it slides, thereby driving the fixing block 3 to clamp or release the saw blade. Support base 5: Support base 5 is the installation base of the saw blade fixing mechanism. The bottom surface has a sliding strip and a support connecting column. The support connecting column is connected to the connecting plate 6. The upper surface has limit plates with limit holes at the four corners, which support components such as hydraulic cylinder 9 and sliding block 4, and ensure the stable operation of the fixing mechanism. Connecting plate 6: Connecting plate 6 is a connecting component. One end is connected to sliding seat 17, and the other end is connected to support base 5 through support connecting column. It transmits the displacement of the correction mechanism to the saw blade fixing mechanism, so that the correction action is synchronously applied to the bimetal band saw blade 2 to realize the adjustment of the saw blade position. Guide rod 7: Guide rod 7 is a limiting and guiding component, which is symmetrically fixed on the side of the fixed block 3 facing the sliding block 4 and slides coaxially with the limiting hole of the support base 5 to ensure that the fixed block 3 moves in a straight line when clamping or releasing the saw blade, and avoids displacement that affects the saw blade fixing effect. Rubber strip 8: Rubber strip 8 is an anti-wear component, fixed on the opposite sides of the fixing blocks 3 on both sides. When the fixing blocks 3 clamp the bimetal band saw blade 2, it buffers the rigid clamping force, reduces the direct friction between the saw blade and the fixing blocks 3, reduces the wear of the saw blade, and extends its service life. Hydraulic cylinder 9: Hydraulic cylinder 9 is the power source of the fixed mechanism. It is fixed on the bottom surface of the support base 5 and is connected to piston rod 10 through transmission. It drives piston rod 10 to extend and retract, providing power for connecting rod 11 to move sliding block 4, so as to realize the clamping and releasing of saw blade by fixed block 3. Piston rod 10: Piston rod 10 is a power transmission component. One end is connected to hydraulic cylinder 9, and the other end is equipped with a connecting block with a hinge shaft and connected to connecting rod 11. It converts the driving force of hydraulic cylinder 9 into linear motion, and drives connecting rod 11 to swing through extension and retraction, thereby driving sliding block 4 to slide. Link 11: Link 11 is a transmission component. The piston rod 10 connecting block and the sliding block 4 are respectively hinged at both ends. It converts the linear motion of the piston rod 10 into the sliding of the sliding block 4, realizes the power transmission, and enables the hydraulic cylinder 9 to drive the fixed block 3 to complete the saw blade fixing action. Support frame 12: The support frame 12 consists of four support columns and a support top plate, which is fixed in the middle of the saw 1. Sensor 13 is installed on the bottom surface, and sensor 24 is installed on the opposite side of the support columns, providing installation support for the sensors, while not affecting the sawing operation of the bimetal band saw blade 2. Sensor 13: Sensor 13 is a D8251 eddy current sensor, which is fixed on the bottom surface of the support frame 12 and above the bimetal band saw blade 2. It monitors the longitudinal position of the saw blade in real time. Once the saw blade deviates, it will send a feedback signal to provide position data for automatic correction. Sensor 2 14: Sensor 2 14 is a D8251 eddy current sensor, which is fixed on the opposite side of the support column of the support frame 12. It monitors the lateral position of the bimetal band saw blade 2 in real time. It works with Sensor 1 13 to fully capture the saw blade offset and ensure the accurate adjustment of the correction mechanism. Fixed seat 15: Fixed seat 15 is the basic component of the first correction assembly. It is fixed on the support plate of the saw 1. It has sliding strips on both sides, and a vertical plate, motor 16 and lead screw 18 in the middle. It provides sliding support for the second sliding seat 19. The second sliding seat 19 is moved by the lead screw 18 to realize the first-level correction. Motor 16: Motor 16 is the power source of the correction mechanism. It is installed on the upright plate of fixed base 15 and sliding base 19 respectively. The output shaft is fixed coaxially with lead screw 18. After receiving the feedback signal from the sensor, it starts to drive lead screw 18 to rotate, providing power for the movement of sliding base 19 and sliding base 17. Sliding seat 17: Sliding seat 17 is the actuating component of the second correction assembly. It has a sliding groove at the bottom that cooperates with the sliding strip of sliding seat 2 19, and the top surface is connected to the connecting plate 6. It is driven to slide by the lead screw 18 on sliding seat 2 19. Through the connecting plate 6, it drives the saw blade fixing mechanism and the saw blade to move, thereby realizing the second-level correction. Lead screw 18: Lead screw 18 is the core component of the correction transmission. It is installed between the vertical plates of fixed seat 15 and sliding seat 19, and is connected to the output shaft of motor 16. Motor 16 drives it to rotate, converting the rotational motion into linear motion of sliding seat 19 and sliding seat 17, and transmitting the correction power. Sliding seat 2 19: Sliding seat 2 19 is the intermediate transmission component of the second correction assembly. The bottom slide groove is connected to the sliding bar of the fixed seat 15. The top surface has a sliding bar, and the middle is equipped with a motor 16 and a lead screw 18. It is driven to move by the lead screw 18 of the fixed seat 15. At the same time, it drives the sliding seat 1 17 to move through its own lead screw 18, so as to realize the connection of the two-stage correction.

[0032] Working principle: During operation, the bimetal band saw blade 2 is first stably installed through the saw blade fixing mechanism. The hydraulic cylinder 9 is activated, and the hydraulic cylinder 9 drives the piston rod 10 to extend and retract along the axis. The connecting block at the end of the piston rod 10 moves accordingly, causing the two connecting rods 11 hinged to it to swing synchronously. The other end of the connecting rod 11 is connected to the hinge shaft on the bottom surface of the sliding block 4. During the swing, the sliding block 4 is pushed to slide along the slide bar on the bottom surface of the support base 5. The sliding block 4 drives the fixed block 3 to move synchronously. The two fixed blocks 3 on both sides approach each other and fit against the surface of the bimetal band saw blade 2 to achieve clamping and fixing of the saw blade. During this process, the guide rod 7 on the fixed block 3 slides coaxially along the limiting holes of the four corner limiting plates of the support base 5 to ensure the stability of the moving trajectory of the fixed block 3 and avoid deviation that would cause the saw blade to be misaligned. At the same time, the rubber strip 8 on the opposite surface of the fixed block 3 makes flexible contact with the bimetal band saw blade 2, which not only enhances the clamping friction to prevent the saw blade from sliding, but also avoids rigid contact that would cause wear on the surface of the saw blade, thus ensuring the service life of the saw blade.

[0033] When the bimetal band saw blade 2 is performing metal cutting operations, both sensor 13 and sensor 24 on the support frame 12 are D8251 eddy current sensors that continuously monitor the position of the saw blade: sensor 13 is located above the saw blade and captures the longitudinal position offset data of the saw blade in real time; sensor 214 is installed on the opposite side of the support column of the support frame 12 and accurately detects the lateral offset of the saw blade. When sensor 13 or sensor 214 detects that the saw blade offset exceeds the preset range, it immediately sends a signal to the motor 16 of the correction mechanism to trigger the automatic correction process.

[0034] After receiving the signal, the correction mechanism starts the two sets of motors 16 respectively: the motor 16 mounted on the upright plate of the fixed base 15 drives the coaxially fixed lead screw 18 to rotate. Since the threaded hole of the bottom connecting plate of the sliding base 19 is threadedly connected to the lead screw 18, and the sliding groove on the bottom surface of the sliding base 19 slides with the sliding strips on both sides of the fixed base 15, the rotation of the lead screw 18 converts the rotational motion into linear motion, causing the sliding base 19 to move along the sliding strip direction of the fixed base 15, thereby realizing the position adjustment of the saw blade in the first dimension; at the same time, the other motor 16 mounted on the upright plate of the sliding base 19 synchronously drives the lead screw 18 between its upright plates to rotate. The threaded hole of the bottom connecting plate of the sliding base 17 is threadedly connected to the lead screw 18, and the sliding groove on the bottom surface of the sliding base 17 slides with the sliding strip on the upper surface of the sliding base 19, with the sliding strips of the fixed base 15 and the sliding strips of the sliding base 19 being perpendicularly corresponding. The rotation of the lead screw 18 causes the sliding base 17 to move along the sliding strip direction of the sliding base 19, thereby realizing the position adjustment of the saw blade in the second dimension.

[0035] When the sliding seat 17 moves, it transmits its displacement synchronously to the support base 5, which is fixed to it, through the connecting plate 6 fixed on the plane of the sliding seat 2 19. The support base 5 is fixed to the connecting plate 6 through the support connecting column. The support base 5 drives the entire saw blade fixing mechanism and the clamped bimetal band saw blade 2 to move together until the sensor 13 and the sensor 2 14 detect that the saw blade has returned to the preset correct position. The motor 16 stops running, and the correction action is completed.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
