Description

Technical Field

[0001] This utility model relates to the field of long bar processing, and in particular to a long bar sawing system. Background Technology

[0002] Long bars are generally round materials of a certain length, mostly produced by stretching or extruding through molds. They require subsequent machining such as sawing, and are typically sawed using a band saw.

[0003] In the prior art, to improve processing efficiency and reduce labor intensity, a sawing system is provided, including a conveyor and a band saw. The band saw is set in the processing area of ​​the conveyor, and a positioning component is set on the conveyor in front of the processing area (along the conveying direction of the conveyor). The positioning component is located at the front of the band saw. When the conveyor transports the long bar to the processing area, after the long bar moves to the set position in the processing area (behind the band saw), the conveyor stops transporting. The positioning component moves laterally under the drive of the drive mechanism, and then moves in the opposite direction of the conveyor transport to the positioning position. Then the conveyor drives the long bar forward until it abuts against the end of the positioning component. The clamping plate in the processing area presses down to clamp the long bar, and the band saw moves horizontally to cut. When the cutting is completed and transport is required, the positioning component resets to avoid interference with the cut product and affecting the transport. When cutting needs to continue, the positioning component needs to move back to the positioning position. To avoid collision, the conveyor stops moving during this process. After the positioning component moves into place, the conveyor drives the remaining long bar to move, and the above steps are repeated.

[0004] While the above technical solutions can guarantee sawing accuracy, the positioning components are located at the front of the processing area and need to be constantly reset and moved for repeated positioning. At the same time, the conveyor needs to work intermittently to cooperate with the positioning components. This means that the conveyor needs to stop conveying not only during sawing but also during positioning, which greatly affects work efficiency. Utility Model Content

[0005] In order to solve the technical problem of low processing efficiency caused by repeated positioning during the sawing of long bars in the prior art, this utility model provides a long bar sawing system that can improve processing efficiency.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a long bar sawing system, including a sawing device and a feeding device. Along the feeding direction, the feeding device is located at the rear of the sawing device. The feeding device includes a support frame, and a positioning element is provided at the front end of the support frame. The feeding device further includes: a movable plate, which is movably disposed on a plurality of the support frames and can move along the length direction of the support frames; a clamping assembly, which is disposed on the movable plate and is used to clamp the end of the long bar; and a driving assembly, which is disposed on the support frame and includes a driving motor connected to the movable plate.

[0007] This invention, by setting the positioning component on the feeding device and located after the sawing device, enables the long bar to be positioned before sawing, thus not affecting the conveying of the finished product after sawing. Furthermore, by driving the long bar axially with the drive motor, the sawing length can be controlled by controlling the moving distance of the moving plate, ensuring product quality. It eliminates the need for repeated positioning when cutting the same long bar, shortens the time the feeding device stops conveying, and improves processing efficiency.

[0008] Furthermore, the clamping assembly includes a clamping cylinder and two clamping rods. The clamping cylinder is disposed on the movable plate. The piston rod of the clamping cylinder is rotatably connected to one end of two connecting rods. The other end of the connecting rods is rotatably connected to one end of the clamping rods. The two clamping rods are arranged opposite to each other and are rotatably disposed on the movable plate.

[0009] This invention uses a linkage-type mechanical gripper, which can adapt to long bars of various diameters and generate a large clamping force to ensure clamping stability.

[0010] Furthermore, both clamping rods are equipped with synchronizing gears, and the two synchronizing gears mesh with each other.

[0011] This invention uses two meshing synchronous gears to ensure that the two clamping rods swing at the same angle. On the one hand, it ensures reliable clamping, and on the other hand, it ensures that the center of the clamping assembly does not change, thus avoiding the long bar material from shifting after clamping and affecting the accuracy of feeding.

[0012] Furthermore, the feeding device also includes a sensor, which is mounted on the moving plate and is used to sense the rear end face of the long bar stock.

[0013] This invention enables the clamping assembly to automatically clamp long bars by setting up sensors, thereby improving the level of automation.

[0014] Furthermore, the movable plate includes a support portion and a mounting portion. The support portion is horizontally disposed on the upper part of the support frame, and the mounting portion is disposed on one side of the support frame. The drive motor is disposed on the mounting portion, and the drive motor is connected to a drive gear. The drive gear meshes with a rack, and the rack is disposed on one side of the support frame along the length direction of the support frame. The drive motor is a servo motor.

[0015] This invention further improves the accuracy of feeding distance control and feeding precision by using a servo motor.

[0016] Furthermore, a displacement sensor is also provided on the support frame, which is used to detect the moving distance of the moving plate.

[0017] This invention, by setting a displacement sensor, can detect the moving distance of the drive motor, avoid feeding deviation caused by the working error of the motor itself, and further improve the feeding accuracy.

[0018] Furthermore, the positioning component is a positioning plate, which is connected to a lifting cylinder. The lifting cylinder is located at the front end of the support frame, and the positioning plate can abut against the end face of the long bar.

[0019] Furthermore, the positioning element is a proximity switch.

[0020] This invention uses a proximity switch as a positioning element to quickly identify the end of a long bar, and does not require lifting or lowering, thus not affecting the conveying of the long bar and further improving work efficiency.

[0021] Furthermore, it also includes at least two transverse conveying devices. The support frame includes multiple adjacent sub-segments, the number of which is one more than the number of transverse conveying devices. The conveying direction of the transverse conveying devices is perpendicular to the moving direction of the moving plate. The transverse conveying devices are arranged between two adjacent sub-segments. The length of the moving plate is greater than the distance between two adjacent sub-segments.

[0022] This invention improves automation and processing efficiency by setting up a transverse conveying device to automatically transfer long bars to the support frame.

[0023] Furthermore, the transverse conveying device includes a base, on which a support seat is movably mounted, and on which a limit block is movably mounted, and on which a V-shaped groove is mounted at the top, the V-shaped groove abutting against the outer circumferential surface of the long bar.

[0024] This invention improves the reliability of feeding long bars onto the support frame by setting a liftable limit block, preventing the long bars from rolling on the support frame and from colliding with the clamping components.

[0025] Furthermore, a lateral drive component is provided on the base, the telescopic rod of the lateral drive component is connected to the support base, and a lifting drive component is provided on the support base, the telescopic rod of the lifting drive component is connected to the limiting block.

[0026] As can be seen from the above technical solutions, this utility model has the following advantages:

[0027] This utility model provides a long bar sawing system. By setting the positioning component on the feeding device and located after the sawing device, the long bar can be positioned before sawing, thus not affecting the conveying of the finished product after sawing. Furthermore, by driving the long bar axially with a drive motor, the sawing length can be controlled by controlling the moving distance of the moving plate, ensuring product quality. Repeated positioning is not required when cutting the same long bar, shortening the time the feeding device stops conveying and improving processing efficiency. Two meshing synchronous gears ensure that the two clamping rods swing at the same angle, guaranteeing reliable clamping and ensuring that the center of the clamping assembly remains unchanged, preventing the long bar from shifting after clamping and affecting the accuracy of feeding. By setting... Sensors enable the clamping assembly to automatically grip long bars, improving automation levels; the use of servo motors further enhances the accuracy of feeding distance control; displacement sensors detect the movement distance of the drive motor, avoiding feeding deviations caused by the motor's own operating errors, further improving feeding precision; a transverse conveyor device enables automatic transfer of long bars to the support frame, improving automation levels and processing efficiency; liftable limit blocks enhance the reliability of feeding long bars to the support frame, preventing them from rolling on the support frame and colliding with the clamping assembly; proximity switches, used as positioning elements, quickly identify the ends of long bars without requiring lifting or lowering, thus improving work efficiency.

[0036] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1

[0038] like Figure 1 and Figure 2As shown in the figure, this specific embodiment provides a long bar sawing system, including a sawing device 30 and a feeding device 33. Along the feeding direction, the feeding device 33 is located at the rear of the sawing device 30. The feeding device 33 includes a support frame 1, a moving plate 3, a clamping assembly 4, a positioning element 32, and a driving assembly. The support frame 1 is used to support the axial movement of the long bar 5. A roller 19 is rotatably arranged on the support frame 1. A positioning element 32 is arranged at the front end of the support frame 1. The positioning element 32 is used to position the end of the long bar 5. The moving plate 3 is movably arranged on multiple support frames 1 via guide rails. The moving plate 3 can move along the length direction of the support frame 1. The clamping assembly 4 is arranged on the moving plate 3. The clamping assembly 4 is used to clamp the end of the long bar 5. The driving assembly is arranged on the support frame 1. The driving assembly includes a driving motor 2. The driving motor 2 is connected to the moving plate 3.

[0039] In this specific embodiment, by setting the positioning element 32 on the feeding device 33 and located after the sawing device 30, the long bar 5 can be positioned before sawing, so as not to affect the conveying of the finished product after sawing. Furthermore, by driving the long bar 5 axially through the drive motor 2, the sawing length can be controlled by controlling the moving distance of the moving plate 3, ensuring product quality. It is not necessary to repeatedly position the same long bar 5 when cutting, which shortens the time when the feeding device 33 stops conveying and improves processing efficiency.

[0040] like Figure 3 As shown, to achieve reliable clamping, in this specific embodiment, the clamping assembly 4 includes a clamping cylinder 20 and two clamping rods 23. The clamping cylinder 20 is mounted on the moving plate 3. The piston rod of the clamping cylinder 20 is rotatably connected to one end of two connecting rods 21. The other end of the connecting rods 21 is rotatably connected to one end of the clamping rods 23. The two clamping rods 23 are arranged opposite to each other and are rotatably mounted on the moving plate 3. By using the mechanical grippers of the connecting rods 21, it can adapt to long bars 5 of various diameters and generate a large clamping force to ensure clamping stability. Furthermore, to avoid scratching the long bars 5, the clamping end of the clamping rods 23 is provided with a protective plate 27, which is made of rubber or plastic.

[0041] like Figure 3 As shown, the feeding device 33 also includes a sensor 26, which is mounted on the moving plate 3. The sensor 26 is used to sense the rear end face of the long bar 5. In this specific embodiment, the sensor 26 is a proximity switch. After the long bar 5 is transferred to the support frame 1, the moving plate 3 moves toward the rear end of the long bar 5 until the sensor 26 senses the long bar 5. At this time, the piston rod of the clamping cylinder 20 retracts, and the clamping ends of the two clamping rods 23 move relative to each other until they are clamped on the outer surface of the long bar 5.

[0042] like Figure 2 As shown, in this specific embodiment, the movable plate 3 includes a support part and a mounting part. The support part is horizontally arranged on the upper part of the support frame 1 via a guide rail. The mounting part is arranged on one side of the support frame 1 via another guide rail. The drive motor 2 is arranged on the mounting part. The drive motor 2 is connected to a drive gear. The drive gear meshes with a rack. The rack is arranged on one side of the support frame 1 along the length direction of the support frame 1. To improve control accuracy, the drive motor 2 is a servo motor.

[0043] The positioning component 32 can be a positioning plate, which is connected to a lifting cylinder. The lifting cylinder is located at the front end of the support frame 1. The positioning plate can abut against the end face of the long bar 5. When the long bar 5 is transferred to the support frame 1, the feeding device 33 is in a stopped feeding state. The positioning cylinder drives the positioning plate to rise. Then, the feeding device 33 starts feeding. The moving plate 3 moves under the drive of the drive component. The clamping component 4 pushes the long bar 5 axially until it abuts against the positioning end face. At this time, the drive motor 2 is in torque control mode. When it senses an increase in torque, it judges that the positioning of the long bar 5 is completed and stops driving the moving plate 3 to move. Then the positioning plate descends, and the moving plate 3 continues to move a set distance to complete the sawing feeding. When it is necessary to continue sawing the same long bar 5, the drive motor 2 is controlled to rotate a set angular displacement to ensure that the moving plate 3 moves a set distance. A fixed distance is sufficient, eliminating the need for a repositioning plate. In this case, the drive motor 2 operates in displacement control mode. However, in this specific embodiment, to further reduce the downtime of the feeding device 33, the positioning element 32 is a proximity switch. The proximity switch is mounted on the front end of the support frame 1 via a bracket. When the long bar 5 is transferred to the support frame 1, the moving plate 3 can move until the long bar 5 is sensed by the proximity switch. Then, the displacement of the drive motor 2 returns to zero, entering displacement control mode, allowing the moving plate 3 to move a set distance to ensure sawing quality. When it is necessary to continue sawing the same long bar 5, the drive motor 2 is controlled to rotate a set angular displacement to ensure that the moving plate 3 moves a set distance. It can be seen that by using a proximity switch as the positioning element 32, the feeding only needs to be stopped during sawing, resulting in a shorter downtime and further improving post-processing efficiency.

[0044] It is understood that the system also includes a controller, and the sawing device 30, drive motor 2, clamping cylinder 20, sensor 26 and positioning component 32 are all electrically connected to the controller; in this specific embodiment, the sawing system also includes a feeding conveyor 31, which is a roller conveyor. Specific Implementation Method Two

[0046] like Figure 4 and Figure 5As shown, this specific embodiment provides a long bar sawing system, which is basically the same as the structure of the first specific embodiment, except that it also includes at least two transverse conveying devices 34. The support frame 1 includes a plurality of adjacent sub-segments, the number of which is one more than the number of transverse conveying devices 34. The plurality of sub-segments are arranged in a straight line. The conveying direction of the transverse conveying device 34 is perpendicular to the moving direction of the moving plate 3. The transverse conveying device 34 is arranged between two adjacent sub-segments. The length of the moving plate 3 is greater than the distance between two adjacent sub-segments.

[0047] This specific embodiment achieves automatic transfer of long bar stock 5 to support frame 1 by setting up a transverse conveying device 34, thereby improving the level of automation and processing efficiency.

[0048] like Figure 6 As shown, in this specific embodiment, the transverse conveying device 34 includes a base 6, on which a support seat 10 is movably mounted via a guide rail. The moving direction of the support seat 10 is perpendicular to the length direction of the support frame 1. A limit block 16 is movably mounted on the support seat 10. A V-shaped groove is provided on the top of the limit block 16, and the V-shaped groove abuts against the outer circumferential surface of the long bar 5. By setting the movable limit block 16, the reliability of the long bar 5 being fed to the support frame can be improved, preventing the long bar 5 from rolling on the support frame 1, and thus preventing the long bar 5 from colliding with the clamping assembly 4. Specifically, the limit block 16 is connected to the support seat 10 via a mounting plate, and a guide rod 13 is vertically mounted between the mounting plate and the support seat 10.

[0049] like Figure 6 As shown in this specific embodiment, a horizontal drive component 11 is provided on the base 6. The telescopic rod of the horizontal drive component 11 is connected to the support base 10. The horizontal drive component 11 is a hydraulic cylinder. A lifting drive component 14 is provided on the support base 10. The telescopic rod of the lifting drive component 14 is connected to the limit block 16. The lifting drive component 14 is a hydraulic cylinder. Both the lifting drive component 14 and the horizontal drive component 11 are electrically connected to the controller.

[0050] In this specific embodiment, the transverse conveying device 34 is provided in two sets, and the support frame 1 is divided into three sub-segments, with the length of the middle sub-segment being greater than the length of its two adjacent sub-segments.

[0051] The working process of the long bar sawing system is as follows:

[0052] The transverse conveying device 34 conveys the long bar 5 to the support frame 1. Then, the lifting drive 14 descends, causing the long bar 5 to disengage from the limiting block 16 and fall onto the roller 19 of the support frame 1. The moving plate 3 moves until the sensor 26 senses the rear end of the long bar 5, and the clamping component 4 clamps it. The moving component continues to move, pushing the long bar 5 towards the positioning component 32 until the positioning component 32 senses the front end of the long bar 5. The drive motor 2 returns to zero and continues to drive the moving plate 3 to move. After the long bar 5 moves a set distance to the sawing position, the drive motor 2 stops working, the sawing device 30 performs sawing, and the unloading conveying device 31 transports the sawn finished product away. At the same time, the drive motor 2 continues to rotate, and the moving plate 3 pushes the long bar 5 to continue moving a set distance for sawing. This process is repeated until the long bar 5 is sawn.

[0053] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0054] 1. By setting the positioning component 32 on the feeding device 33 and in front of the sawing device 30, the long bar 5 can be positioned before sawing, so as not to affect the conveying of the finished product after sawing. Furthermore, by driving the long bar 5 axially through the drive motor 2, the sawing length can be controlled by controlling the moving distance of the moving plate 3, ensuring product quality. It is not necessary to repeatedly position the same long bar 5 when cutting, which shortens the time when the feeding device 33 stops conveying and improves processing efficiency.

[0055] 2. The two meshing synchronous gears 28 can ensure that the two clamping rods 23 swing at the same angle. On the one hand, this ensures reliable clamping, and on the other hand, it ensures that the center of the clamping assembly 4 does not change, thus avoiding the long bar material 5 from shifting after clamping and affecting the accuracy of feeding.

[0056] 3. By setting sensor 26, the clamping component 4 can automatically clamp the long bar material 5, thereby improving the level of automation;

[0057] 4. By using a servo motor, the accuracy of the feeding distance control is further improved; by setting a displacement sensor, the moving distance of the drive motor 2 can be detected, avoiding feeding deviation caused by the working error of the moving motor itself, and further improving the feeding accuracy.

[0058] 5. By setting up a transverse conveyor device 34, the long bar material 5 is automatically transferred to the support frame 1, which improves the level of automation and processing efficiency;

[0059] 6. By setting a liftable limit block 16, the reliability of feeding the long bar 5 to the support frame can be improved, the long bar 5 can be prevented from rolling on the support frame 1, and the long bar 5 can be prevented from colliding with the clamping component 4.

[0060] 7. The proximity switch 32 can quickly identify the end of the long bar 5 without lifting or lowering, thus improving work efficiency.

[0061] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
