Description

Technical Field

[0001] This invention relates to the field of sawing technology, and more specifically, to an integrated sawing machine and sawing method. Background Technology

[0002] A band saw is a device for cutting bars, cutting long bars into bars of a certain length for later use. During bar sawing, the bars are first loaded onto the band saw, then conveyed under the saw band. After the saw band completes the sawing, the cut bars are conveyed outwards for unloading. Subsequently, the bars are transferred to an inspection station to test their length and weight. In actual operation, it has been found that sometimes the sawing length of the bars deviates significantly, failing to meet sawing requirements. The inspection process requires transferring the bars, increasing workload and reducing efficiency. Chinese patent application number 2009101019926 discloses a horizontal metal band saw, in which the saw frame is lowered to saw the upper ring portion of a hollow cylindrical workpiece, and then the drive roller on the V-shaped workpiece seat rotates, causing the workpiece to rotate in the same direction as the saw wheel. Under the action of the clamping cylinder, the two pressure plates press against the workpiece from opposite directions, and the roller closest to the workpiece contacts and clamps the workpiece. The rollers on the pressure plates rotate together with the rotating workpiece, and the rotating saw band gradually saws the other annular parts of the rotating workpiece. The throat depth of the saw frame can be greatly reduced compared to a general horizontal metal band saw, and the sawing time can also be reduced accordingly. However, sometimes the sawing length deviation of the bar stock is large, which cannot meet the sawing requirements. The inspection process requires the bar stock to be transferred, which increases the workload and reduces the work efficiency. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides an integrated sawing machine and sawing method, which provides accurate and reliable sawing length of bar stock, and the bar stock is directly transferred to the detection device after cutting for detection, which helps to reduce workload and improve work efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an integrated sawing machine, including a bed frame and a saw frame, the saw frame being lifted and moved on the sawing machine, a conveyor frame for loading and conveying bar stock is arranged below the saw frame, a clamping and pushing mechanism is installed on the sawing machine, the clamping and pushing mechanism includes two front clamps and two rear clamps, the two front clamps and two rear clamps respectively clamp and position the bar stock, a downward-facing vertical distance measuring sensor is installed on the saw frame, and a lateral distance measuring sensor facing the end face of the bar stock is installed on the conveyor frame; a detection mechanism is arranged in front of the conveyor frame, and the bar stock that has been sawn is transferred to the detection mechanism for detection.

[0005] During the bar sawing operation, the bars are first loaded onto the conveyor frame, which pushes the bars forward. A vertical distance sensor detects the bar's arrival, and a horizontal distance sensor detects the distance to the bar's front end for secondary confirmation, thus ensuring the bar is in place. This secondary confirmation improves the accuracy of the bar's position. After the bar is in place, two rear clamps hold the bar and push it forward. Once in place, two front clamps hold and position the bar. At this point, the saw frame is positioned between the front and rear clamps and moves downward to saw the bar. During this process, the front and rear clamps position the bar at the front and rear of the sawing location, ensuring reliable positioning. After sawing, the front clamps move forward, releasing the bar and returning to their original position. The rear clamps are also released and move backward to their original position. The robotic arm then transfers the sawn bar to the inspection mechanism for testing. The entire bar sawing process is completed automatically. The bar is conveyed with a second confirmation of its position, which improves the accuracy of the bar's position and thus the accuracy of the sawing length. The robotic arm transfers the sawn bars to the inspection mechanism for inspection. The inspection operation is convenient, which helps to reduce workload and improve work efficiency.

[0006] Preferably, the testing mechanism includes a testing frame and a support frame, with a weighing sensor installed between the support frame and the testing frame, distance sensors installed at both ends of the support frame, and a laser marking device installed on the testing frame.

[0007] The sawn bars are loaded onto a support frame, and their weight is detected by a load cell. Distance sensors installed at both ends of the support frame detect the distance between the two ends of the bar, thereby calculating the bar's length. The information of the bar is then laser-marked onto the bar's surface using a laser marking machine.

[0008] Preferably, a lifting pusher is installed on the testing frame, and two oppositely arranged testing clamps are installed on the support frame. A return spring is installed between the testing clamps and the support frame. When the lifting pusher rises, it pushes the two testing clamps closer to each other to clamp and correct the deviation of the bar. When the lifting pusher falls, it separates from the testing clamps.

[0009] After the sawn bars are loaded onto the support frame, the lifting pusher rises and moves the two detection clamps closer together, thus clamping and correcting the bars. After correction, the length of the bars is measured to ensure the accuracy of the length measurement. When measuring the weight of the bars, the lifting pusher moves downward and separates from the detection clamps to avoid the pusher affecting the measurement data.

[0010] Preferably, U-shaped positioning seats are provided at both ends of the support frame, with the openings of the two positioning seats facing each other.

[0011] Two U-shaped positioning seats position the two ends of the bar to prevent the bar from slipping off the support frame.

[0012] Preferably, the saw is equipped with a front slide and a rear slide that can move back and forth, with two front clamps that can move left and right and are mounted on the front slide, and two rear clamps that can move left and right and are mounted on the rear slide.

[0013] The front slide and the rear slide can move back and forth, thereby enabling the front clamp and the rear clamp to move back and forth, which facilitates the pushing and positioning of the bar.

[0014] Preferably, clamping blocks and preload springs are installed at the ends of both the front and rear clamping seats. The preload springs abut against the clamping blocks, which are slidably disposed. Turntables are hinged to the ends of both the front and rear clamping seats. The turntables are connected to clamping arms, and pressure blocks are connected to the clamping arms. A gear ring is provided on the turntables, and a rack is provided on the clamping blocks. The rack meshes with the gear rings for transmission. The clamping blocks clamp onto the bar, and the pressure blocks press against the bar.

[0015] During the clamping process of the front and rear clamps, the clamping blocks first contact the bar. As the two front or two rear clamps move closer to each other, the clamping blocks move towards the preload spring side. This drives the turntable to rotate through the meshing of the rack and pinion gears. The clamping arm rotates with the turntable. When the clamping blocks move to the locking position, the bar is clamped in place, and the pressure block presses firmly onto the bar. This structural design not only achieves clamping and positioning of the bar but also pressure positioning, preventing the bar from vertically swaying during sawing and ensuring the sawing effect.

[0016] Preferably, a number of feeding and correction mechanisms are installed on the conveyor frame at intervals. Each feeding and correction mechanism includes two oppositely arranged feeding clamps. The feeding clamps are slidably arranged, and correction heads are installed on the feeding clamps. A buffer spring is installed between the correction head and the feeding clamps. The correction head clamps and corrects the bar stock.

[0017] After the bar stock is loaded onto the conveyor frame, the two oppositely positioned feeding clamps move closer to each other, causing the alignment head to clamp the bar stock and achieve alignment and positioning. A buffer spring is installed between the alignment head and the feeding clamps. In the initial stage when the alignment head clamps the bar stock, it can buffer the movement and avoid damage to the surface of the bar stock from hard contact.

[0018] Preferably, a buffer chamber is provided on the feeding clamp, and one end of the correction head is adapted to be installed in the buffer chamber. The buffer chamber is connected to the liquid storage tank through a flow pipe. A solenoid valve is installed on the flow pipe, and a positioning sensor is installed on the conveyor frame. After the positioning sensor detects that the feeding clamp has slid into place, the solenoid valve closes.

[0019] The buffer chamber is filled with buffer solution. During the compression of the buffer spring by the alignment head, the buffer solution is squeezed out of the buffer chamber into the storage tank. Once the position sensor detects that the loading clamp has slid into place, the solenoid valve closes, sealing the buffer chamber and thus positioning the alignment head, preventing it from moving. The alignment head then completes the alignment and positioning of the bar, ensuring the accuracy of the bar loading position. After alignment is complete, the loading clamp returns to its original position, the solenoid valve opens, and the alignment head returns to its original position to prepare for the loading and alignment of the next bar.

[0020] A sawing method using an integrated saw to saw bar stock includes the following steps: S1, loading the bar stock onto a conveyor frame, which pushes the bar stock forward; S2, a vertical distance sensor detects the bar stock's arrival position, and a horizontal distance sensor detects the distance to the front end of the bar stock for secondary confirmation of arrival; S3, two rear clamps clamp the bar stock and push it forward; S4, once the bar stock is in position, two front clamps hold and position it; S5, the saw frame moves downward to saw the bar stock; S6, after sawing, the front clamps hold the bar stock and move it forward, releasing the front clamps and returning to their original positions, releasing the rear clamps and moving them backward to their original positions, and a robotic arm transfers the sawn bar stock to an inspection mechanism for inspection; S7, repeating S3 to S6.

[0021] The entire bar sawing process is completed automatically. The bar is conveyed with a second confirmation of its position, which improves the accuracy of the bar's position and thus the accuracy of the sawing length. The robotic arm transfers the sawn bars to the inspection mechanism for inspection. The inspection operation is convenient, which helps to reduce workload and improve work efficiency.

[0022] Preferably, in step S5, the vertical distance sensor detects the distance between the saw blade and the bar. Before the saw blade approaches the bar, the saw frame moves downward quickly, and after the saw blade approaches the bar, the saw frame moves downward slowly to saw the bar.

[0023] Before the saw blade approaches the bar, the saw frame descends rapidly, thus speeding up the sawing process and improving work efficiency.

[0024] Compared with the prior art, the beneficial effects of the present invention are: (1) The entire sawing process of the bar is completed automatically, and the bar can be confirmed to be in place twice during the conveying process, which is conducive to improving the accuracy of the bar conveying position and thus improving the accuracy of the sawing length. The sawn bar is transferred to the detection mechanism for detection by the robotic arm, which is convenient for detection operation, which is conducive to reducing the workload and improving work efficiency; (2) After the sawn bar is loaded into the support frame, the two detection clamps move towards each other to clamp and correct the bar. After correction, the length of the bar is measured to ensure the accuracy of the length detection; (3) The front clamp and the rear clamp are aligned with each other. During the bar clamping process, not only is the bar clamped and positioned, but the bar is also pressed and positioned. This dual approach prevents the bar from swaying vertically during the sawing process and ensures the sawing effect. (4) After the bar is loaded onto the conveyor frame, the two oppositely positioned loading clamps move towards each other, causing the correction head to clamp the bar and achieve the correction and positioning of the bar. In the initial stage when the correction head clamps the bar, the correction head can buffer and avoid hard contact that could damage the surface of the bar. After the correction is in place, the magnetic valve closes, sealing the buffer chamber, thereby achieving the positioning of the correction head and preventing it from moving, thus ensuring the accuracy of the bar loading position.

[0034] Two front clamps 7 are respectively installed on the left and right sides of the front slide 9.

The front slide 9 is threadedly fitted with the front screw and slidably connected to the two front slide rails. The rotation of the front screw realizes the forward and backward movement of the front slide 9. A front piston cylinder corresponding to the front clamp 7 is installed on the front slide 9, and the telescopic rod of the front piston cylinder is connected to the front clamp 7.

A rear screw and two rear slide rails corresponding to the rear slide 10 are installed on the saw. The rear screw is driven by a motor. The rear slide 10 is threadedly fitted with the rear screw and slidably connected to the two rear slide rails. The rotation of the rear screw enables the rear slide 10 to move back and forth. A rear piston cylinder corresponding to the rear clamp 8 is installed on the rear slide 10, and the extension rod of the rear piston cylinder is connected to the rear clamp 8.

[0036] A vertical distance sensor 11 facing downwards is installed on the saw frame 2, and a horizontal distance sensor 12 facing the end face of the bar is installed on the conveyor frame 4; the horizontal distance sensor 12 is installed at the end of the conveyor frame 4. A detection mechanism is set in front of the conveyor frame 4, and the sawn bar is transferred to the detection mechanism for detection.

[0037] The testing mechanism includes a testing frame 13 and a support frame 14. A load cell 15 is installed between the support frame 14 and the testing frame 13. The load cell 15 is fixedly mounted on the testing frame 13, and the support frame 14 is supported on the load cell 15. Distance sensors 16 are installed at both ends of the support frame 14. A laser marking device 17 is installed on the testing frame 13. U-shaped positioning seats 18 are provided at both ends of the support frame 14, with the openings of the two positioning seats 18 facing each other. A recessed V-shaped support groove 19 is provided on the upper surface of the support frame 14. The support frame 14 includes a base plate 20 and a top plate 21, with several spaced vertical plates 22 connecting the base plate 20 and the top plate 21. The support groove 19 is provided on the top plate 21. Windows 23 are provided on the positioning seats 18, and the two distance sensors 16 are respectively positioned facing the two windows 23. The laser emitted by the laser marking device 17 passes through the windows 23 and illuminates the end face of the bar.

[0038] A sawing method using an integrated sawing machine to saw bars includes the following steps: S1, loading the bars onto a conveyor frame 4, which pushes the bars forward. A gripper on a robotic arm grasps the bars and transfers them to the conveyor frame 4. Conveying rollers 5 on the conveyor frame 4 support the bars, and a motor drives the conveying rollers 5 to rotate, thereby conveying the bars forward.

[0039] S2, the vertical distance sensor 11 detects that the bar is in place in the vertical direction, and then the horizontal distance sensor 12 detects the distance to the front end of the bar for secondary confirmation of the position; at this time, the starting position of the end of the bar is determined.

[0040] S3, the two rear clamps 8 approach each other to clamp the bar and move forward through the rear slide 10 to push the bar forward. The pushing distance is determined according to the required sawing length.

[0041] S4, the bar is pushed into place, and the two front clamps 7 move closer to each other to clamp and position the bar; at this time, both the two front clamps 7 and the two rear clamps 8 clamp and position the bar, ensuring the stability of sawing.

[0042] S5, the saw frame 2 moves downward to saw the bar. The vertical distance sensor 11 detects the distance between the saw frame 2 and the bar. Before the saw blade 3 approaches the bar, the saw frame 2 moves downward quickly; after the saw blade 3 approaches the bar, the saw frame 2 moves downward slowly to saw the bar. The saw frame 2 descends quickly before the saw blade 3 approaches the bar, thus accelerating the sawing process and improving work efficiency.

[0043] S6, after sawing, the front clamp 7 clamps the bar and moves forward. Once in position, the front clamp 7 is released and returns to its original position. Simultaneously, the rear clamp 8 is released and moves backward to its original position. The robotic arm transfers the sawn bar to the inspection mechanism for testing. During inspection, the weight of the bar is detected by the weighing sensor 15.

The information of the bar is laser-marked onto the surface of the bar using a laser. After inspection, the robotic arm transfers the bar from the support frame 14 to the unloading station for storage.

[0044] S7, repeat S3 to S6.

[0045] The entire sawing process for the bar is completed automatically. The bar is conveyed with secondary positioning confirmation, improving the accuracy of the bar's position and thus the precision of the sawing length. The robotic arm transfers the sawn bars to the inspection mechanism for testing. The inspection operation is convenient, reducing workload and improving work efficiency. Before the saw blade 3 approaches the bar, the saw frame 2 descends rapidly, accelerating the sawing pace and further improving work efficiency.

[0046] Example 2: An integrated saw (see...) Figure 1 , Figure 2 , Figure 4The saw includes a bed frame 1 and a saw frame 2. The saw frame 2 is mounted on the sawing machine with adjustable height. A saw blade 3 is mounted on the saw frame 2, and two pulleys are installed on the saw frame 2.

Two opposing columns are set on the sawing machine, and the saw blade 3 is mounted on the columns with adjustable height. A lifting piston cylinder is installed on the sawing machine, which drives the saw frame 2 to move up and down. The saw frame 2 is set at an angle to facilitate the placement of the saw blade 3 and prevent interference between the saw frame 2 and the bar stock. A conveyor frame 4 is set below the saw frame 2 to load and transport the bar stock. Multiple conveyor rollers 5 are installed at intervals on the conveyor frame 4. There is a chain drive between adjacent conveyor rollers 5. The motor drives the conveyor rollers 5 to rotate, and there is a chain drive between the output shaft of the motor and any one of the conveyor rollers 5. A V-shaped groove 6 is set in the middle of the outer wall of the conveyor roller 5, and the bar stock is supported in the V-shaped groove 6, which is stable and reliable.

[0047] A clamping and pushing mechanism is installed on the sawing machine. The clamping and pushing mechanism includes two front clamps 7 and two rear clamps 8, which clamp and position the bar stock respectively. The two front clamps 7 are placed on the left and right sides of the conveyor frame 4, and the two rear clamps 8 are placed on the left and right sides of the conveyor frame 4.

[0049] Two rear clamps 8 are respectively installed on the left and right sides of the rear slide 10. A rear screw and two rear slide rails corresponding to the rear slide 10 are installed on the saw. The rear screw is driven by a motor. The rear slide 10 is threadedly fitted with the rear screw and slidably connected to the two rear slide rails. The rotation of the rear screw enables the rear slide 10 to move back and forth. A rear piston cylinder corresponding to the rear clamp 8 is installed on the rear slide 10, and the extension rod of the rear piston cylinder is connected to the rear clamp 8.

[0050] A vertical distance sensor 11 facing downwards is installed on the saw frame 2, and a horizontal distance sensor 12 facing the end face of the bar is installed on the conveyor frame 4; the horizontal distance sensor 12 is installed at the end of the conveyor frame 4. A detection mechanism is set in front of the conveyor frame 4, and the sawn bar is transferred to the detection mechanism for detection.

[0051] The testing mechanism includes a testing frame 13 and a support frame 14. A load cell 15 is installed between the support frame 14 and the testing frame 13. The load cell 15 is fixedly mounted on the testing frame 13, and the support frame 14 is supported on the load cell 15. Distance sensors 16 are installed at both ends of the support frame 14. A laser marking device 17 is installed on the testing frame 13. U-shaped positioning seats 18 are provided at both ends of the support frame 14, with the openings of the two positioning seats 18 facing each other. A recessed V-shaped support groove 19 is provided on the upper surface of the support frame 14. The support frame 14 includes a base plate 20 and a top plate 21, with several spaced vertical plates 22 connecting the base plate 20 and the top plate 21. The support groove 19 is provided on the top plate 21. Windows 23 are provided on the positioning seats 18, and the two distance sensors 16 are respectively positioned facing the two windows 23. The laser emitted by the laser marking device 17 passes through the windows 23 and illuminates the end face of the bar.

[0052] A lifting pusher 24 is installed on the inspection frame 13, and two opposing inspection clamps 25 are installed on the support frame 14. A return spring 26 is installed between the inspection clamps 25 and the support frame 14. When the lifting pusher 24 rises, it pushes the two inspection clamps 25 closer together to clamp and correct the deviation of the bar. When the lifting pusher 24 falls, it separates from the inspection clamps 25. A detachable clamping plate 27 is provided on the opposite surface of the inspection clamps 25, and the bar is clamped and corrected by the clamping plate 27. A detection piston cylinder 28 is installed on the detection frame 13. A lifting push block 24 is connected to the telescopic rod of the detection piston cylinder 28. The lifting push block 24 has a pushing surface 29 that is inclined from top to bottom and outward on both sides. An extension rod 30 is provided on the detection clamp 25. The extension rods 30 on the two detection clamps 25 are staggered. A push column 31 is connected to the extension rod 30. The push column 31 abuts against the pushing surface 29. A guide rail 32 is provided on the support frame 14. The bottom of the detection clamp 25 is slidably connected to the guide rail 32. An avoidance groove is provided on the top plate 21. The detection clamp 25 passes through the avoidance groove.

[0053] After the sawn bars are loaded onto the support frame 14, the lifting push block 24 rises, causing the two pushing surfaces 29 to abut against the push column 31. This pushes the two detection clamps 25 to move closer to each other, clamping and correcting the bar. After correction, the length of the bar is measured to ensure the accuracy of the length measurement. When measuring the weight of the bar, the lifting push block 24 moves downward and separates from the detection clamps 25 to prevent the lifting push block 24 from affecting the measurement data.

[0054] A sawing method using an integrated sawing machine to saw bars includes the following steps: S1, loading the bars onto a conveyor frame 4, which pushes the bars forward. A gripper on a robotic arm grasps the bars and transfers them to the conveyor frame 4. Conveying rollers 5 on the conveyor frame 4 support the bars, and a motor drives the conveying rollers 5 to rotate, thereby conveying the bars forward.

[0055] S2, the vertical distance sensor 11 detects that the bar is in place in the vertical direction, and then the horizontal distance sensor 12 detects the distance to the front end of the bar for secondary confirmation of the position; at this time, the starting position of the end of the bar is determined.

[0056] S3, the two rear clamps 8 approach each other to clamp the bar and move forward through the rear slide 10 to push the bar forward. The pushing distance is determined according to the required sawing length.

[0057] S4, the bar is pushed into place, and the two front clamps 7 move closer to each other to clamp and position the bar; at this time, both the two front clamps 7 and the two rear clamps 8 clamp and position the bar, ensuring the stability of sawing.

[0058] S5, the saw frame 2 moves downward to saw the bar. The vertical distance sensor 11 detects the distance between the saw frame 2 and the bar. Before the saw blade 3 approaches the bar, the saw frame 2 moves downward quickly; after the saw blade 3 approaches the bar, the saw frame 2 moves downward slowly to saw the bar. The saw frame 2 descends quickly before the saw blade 3 approaches the bar, thus accelerating the sawing process and improving work efficiency.

[0059] S6, after sawing, the front clamp 7 clamps the bar and moves forward. Once in position, the front clamp 7 is released and returns to its original position. Simultaneously, the rear clamp 8 is released and moves backward to its original position. The robotic arm transfers the sawn bar to the inspection mechanism for inspection. During inspection, the weight of the bar is detected by the weighing sensor 15. Distance sensors 16 installed at both ends of the support frame 14 detect the distance between the two ends of the bar, thereby calculating the length of the bar. During weight measurement, the lifting push block 24 descends to its low position, separating the pushing surface 29 on the lifting push block 24 from the push column 31. Before length measurement, the lifting push block 24 rises, causing the two pushing surfaces 29 to abut against the push column 31, thereby pushing the two inspection clamps 25 to move closer to each other, clamping and correcting the bar. After correction, the length of the bar is measured to ensure the accuracy of the length detection. The information of the bar is laser-printed onto the surface of the bar by the laser marking machine. After inspection, the robotic arm transfers the bar from the support frame 14 to the unloading station for storage.

[0060] S7, repeat S3 to S6.

[0061] The entire sawing process for the bar is completed automatically. The bar is conveyed with secondary positioning confirmation, improving the accuracy of the bar's position and thus the precision of the sawing length. The robotic arm transfers the sawn bars to the inspection mechanism for testing. The inspection operation is convenient, reducing workload and improving work efficiency. Before the saw blade 3 approaches the bar, the saw frame 2 descends rapidly, accelerating the sawing pace and further improving work efficiency.

[0062] Example 3: An integrated saw (see...) Figure 2 , Figure 4, Figure 5 The saw includes a bed frame 1 and a saw frame 2. The saw frame 2 is mounted on the sawing machine with adjustable height. A saw blade 3 is mounted on the saw frame 2, and two pulleys are installed on the saw frame 2. The two ends of the saw blade 3 are connected to the pulleys for transmission, and the rotation of the pulleys drives the saw blade 3 to rotate. Two opposing columns are set on the sawing machine, and the saw blade 3 is mounted on the columns with adjustable height. A lifting piston cylinder is installed on the sawing machine, which drives the saw frame 2 to move up and down. The saw frame 2 is set at an angle to facilitate the placement of the saw blade 3 and prevent interference between the saw frame 2 and the bar stock. A conveyor frame 4 is set below the saw frame 2 to load and transport the bar stock. Multiple conveyor rollers 5 are installed at intervals on the conveyor frame 4. There is a chain drive between adjacent conveyor rollers 5. The motor drives the conveyor rollers 5 to rotate, and there is a chain drive between the output shaft of the motor and any one of the conveyor rollers 5. A V-shaped groove 6 is set in the middle of the outer wall of the conveyor roller 5, and the bar stock is supported in the V-shaped groove 6, which is stable and reliable.

[0063] Several spaced-apart feeding and correction mechanisms are installed on the conveyor frame 4. In this embodiment, two feeding and correction mechanisms are provided. Each feeding and correction mechanism includes two oppositely arranged feeding clamps 33, which are slidably disposed. Correction screws 34 and sliding rods 35 corresponding to the feeding clamps 33 are installed on the conveyor frame 4. The correction screws 34 are threadedly connected to the feeding clamps 33, and the sliding rods 35 are slidably inserted into the feeding clamps 33. A chain drive is established between the correction screws 34 of the two feeding and correction mechanisms, and the correction screws 34 are driven by a motor. A correction head 36 is installed on the feeding clamp 33, with a pad 37 at the end of the correction head 36. A buffer spring 38 is installed between the correction head 36 and the feeding clamp 33. The correction head 36 clamps and corrects the bar stock. A buffer chamber 39 is provided on the feeding clamp 33. One end of the correction head 36 is adapted to be installed in the buffer chamber 39. The buffer spring 38 is installed in the buffer chamber 39. The buffer chamber 39 is connected to the liquid storage tank through the flow pipe. A solenoid valve 40 is installed on the flow pipe. A position sensor 41 is installed on the conveyor frame 4. After the position sensor 41 detects that the feeding clamp 33 has slid into place, the solenoid valve 40 closes.

[0064] After the bar stock is loaded onto the conveyor frame 4, the two opposing loading clamps 33 move closer to each other, causing the correction head 36 to clamp the bar stock, thus achieving the correction and positioning of the bar stock. A buffer spring 38 is installed between the correction head 36 and the loading clamp 33. In the initial stage when the correction head 36 clamps the bar stock, it can buffer the movement and avoid damage to the surface of the bar stock from hard contact. The buffer chamber 39 is filled with buffer solution. During the process of the correction head 36 compressing the buffer spring 38, the buffer solution is squeezed out of the buffer chamber 39 into the storage tank. After the position sensor 41 detects that the loading clamp 33 has slid into place, the solenoid valve 40 closes, and the buffer chamber 39 is closed, thereby achieving the positioning of the correction head 36 and preventing it from moving. At this time, the correction head 36 completes the correction and positioning of the bar stock, ensuring the accuracy of the bar stock loading position. After the correction is completed, the loading clamp 33 returns to its original position, and the solenoid valve 40 opens, causing the correction head 36 to return to its original position so as to correct the loading of the next bar.

[0065] A clamping and pushing mechanism is installed on the sawing machine. The clamping and pushing mechanism includes two front clamps 7 and two rear clamps 8, which clamp and position the bar stock respectively. The two front clamps 7 are placed on the left and right sides of the conveyor frame 4, and the two rear clamps 8 are placed on the left and right sides of the conveyor frame 4. The sawing machine is equipped with front slides 9 and rear slides 10 that can move back and forth. The saw frame 2 is placed between the front slides 9 and rear slides 10. The two front clamps 7 are mounted on the front slides 9 and the two rear clamps 8 are mounted on the rear slides 10 and the two rear clamps 8 are mounted on the rear slides 10.

[0066] Two front clamps 7 are respectively installed on the left and right sides of the front slide 9. A front screw and two front slide rails corresponding to the front slide 9 are installed on the saw. The front screw is driven by a motor. The front slide 9 is threadedly fitted with the front screw and slidably connected to the two front slide rails. The rotation of the front screw realizes the forward and backward movement of the front slide 9. A front piston cylinder corresponding to the front clamp 7 is installed on the front slide 9, and the telescopic rod of the front piston cylinder is connected to the front clamp 7.

[0067] Two rear clamps 8 are respectively installed on the left and right sides of the rear slide 10. A rear screw and two rear slide rails corresponding to the rear slide 10 are installed on the saw. The rear screw is driven by a motor. The rear slide 10 is threadedly fitted with the rear screw and slidably connected to the two rear slide rails. The rotation of the rear screw enables the rear slide 10 to move back and forth. A rear piston cylinder corresponding to the rear clamp 8 is installed on the rear slide 10, and the extension rod of the rear piston cylinder is connected to the rear clamp 8.

[0068] A vertical distance sensor 11 facing downwards is installed on the saw frame 2, and a horizontal distance sensor 12 facing the end face of the bar is installed on the conveyor frame 4; the horizontal distance sensor 12 is installed at the end of the conveyor frame 4. A detection mechanism is set in front of the conveyor frame 4, and the sawn bar is transferred to the detection mechanism for detection.

[0069] The testing mechanism includes a testing frame 13 and a support frame 14. A load cell 15 is installed between the support frame 14 and the testing frame 13. The load cell 15 is fixedly mounted on the testing frame 13, and the support frame 14 is supported on the load cell 15. Distance sensors 16 are installed at both ends of the support frame 14. A laser marking device 17 is installed on the testing frame 13. U-shaped positioning seats 18 are provided at both ends of the support frame 14, with the openings of the two positioning seats 18 facing each other. A recessed V-shaped support groove 19 is provided on the upper surface of the support frame 14. The support frame 14 includes a base plate 20 and a top plate 21, with several spaced vertical plates 22 connecting the base plate 20 and the top plate 21. The support groove 19 is provided on the top plate 21. Windows 23 are provided on the positioning seats 18, and the two distance sensors 16 are respectively positioned facing the two windows 23. The laser emitted by the laser marking device 17 passes through the windows 23 and illuminates the end face of the bar.

[0070] A lifting pusher 24 is installed on the inspection frame 13, and two opposing inspection clamps 25 are installed on the support frame 14. A return spring 26 is installed between the inspection clamps 25 and the support frame 14. When the lifting pusher 24 rises, it pushes the two inspection clamps 25 closer together to clamp and correct the deviation of the bar. When the lifting pusher 24 falls, it separates from the inspection clamps 25. A detachable clamping plate 27 is provided on the opposite surface of the inspection clamps 25, and the bar is clamped and corrected by the clamping plate 27. A detection piston cylinder 28 is installed on the detection frame 13. A lifting push block 24 is connected to the telescopic rod of the detection piston cylinder 28. The lifting push block 24 has a pushing surface 29 that is inclined from top to bottom and outward on both sides. An extension rod 30 is provided on the detection clamp 25. The extension rods 30 on the two detection clamps 25 are staggered. A push column 31 is connected to the extension rod 30. The push column 31 abuts against the pushing surface 29. A guide rail 32 is provided on the support frame 14. The bottom of the detection clamp 25 is slidably connected to the guide rail 32. An avoidance groove is provided on the top plate 21. The detection clamp 25 passes through the avoidance groove.

[0071] After the sawn bars are loaded onto the support frame 14, the lifting push block 24 rises, causing the two pushing surfaces 29 to abut against the push column 31. This pushes the two detection clamps 25 to move closer to each other, clamping and correcting the bar. After correction, the length of the bar is measured to ensure the accuracy of the length measurement. When measuring the weight of the bar, the lifting push block 24 moves downward and separates from the detection clamps 25 to prevent the lifting push block 24 from affecting the measurement data.

[0072] A sawing method using an integrated sawing machine to saw bars includes the following steps: S1, loading the bars onto a conveyor frame 4, which pushes the bars forward. A gripper on a robotic arm picks up the bars and transfers them onto the conveyor frame 4. Conveying rollers 5 on the conveyor frame 4 support the bars. Two opposing loading clamps 33 move towards each other, causing a correction head 36 to clamp the bars, achieving correction and positioning. After correction, the loading clamps 33 return to their original position, and a solenoid valve 40 opens, causing the correction head 36 to return to its original position for loading and correction of the next bar. A motor drives the conveyor rollers 5 to rotate, thus conveying the bars forward.

[0073] S2, the vertical distance sensor 11 detects that the bar is in place in the vertical direction, and then the horizontal distance sensor 12 detects the distance to the front end of the bar for secondary confirmation of the position; at this time, the starting position of the end of the bar is determined.

[0074] S3, the two rear clamps 8 approach each other to clamp the bar and move forward through the rear slide 10 to push the bar forward. The pushing distance is determined according to the required sawing length.

[0075] S4, the bar is pushed into place, and the two front clamps 7 move closer to each other to clamp and position the bar; at this time, both the two front clamps 7 and the two rear clamps 8 clamp and position the bar, ensuring the stability of sawing.

[0076] S5, the saw frame 2 moves downward to saw the bar. The vertical distance sensor 11 detects the distance between the saw frame 2 and the bar. Before the saw blade 3 approaches the bar, the saw frame 2 moves downward quickly; after the saw blade 3 approaches the bar, the saw frame 2 moves downward slowly to saw the bar. The saw frame 2 descends quickly before the saw blade 3 approaches the bar, thus accelerating the sawing process and improving work efficiency.

[0077] S6, after sawing, the front clamp 7 clamps the bar and moves forward. Once in position, the front clamp 7 is released and returns to its original position. Simultaneously, the rear clamp 8 is released and moves backward to its original position. The robotic arm transfers the sawn bar to the inspection mechanism for inspection. During inspection, the weight of the bar is detected by the weighing sensor 15. Distance sensors 16 installed at both ends of the support frame 14 detect the distance between the two ends of the bar, thereby calculating the length of the bar. During weight measurement, the lifting push block 24 descends to its low position, separating the pushing surface 29 on the lifting push block 24 from the push column 31. Before length measurement, the lifting push block 24 rises, causing the two pushing surfaces 29 to abut against the push column 31, thereby pushing the two inspection clamps 25 to move closer to each other, clamping and correcting the bar. After correction, the length of the bar is measured to ensure the accuracy of the length detection. The information of the bar is laser-printed onto the surface of the bar by the laser marking machine. After inspection, the robotic arm transfers the bar from the support frame 14 to the unloading station for storage.

[0078] S7, repeat S3 to S6.

[0079] The entire sawing process for the bar is completed automatically. The bar is conveyed with secondary positioning confirmation, improving the accuracy of the bar's position and thus the precision of the sawing length. The robotic arm transfers the sawn bars to the inspection mechanism for testing. The inspection operation is convenient, reducing workload and improving work efficiency. Before the saw blade 3 approaches the bar, the saw frame 2 descends rapidly, accelerating the sawing pace and further improving work efficiency.

[0080] Example 4: An integrated saw (see...) Figure 2 , Figure 4 , Figure 5 , Figure 6 The saw includes a bed frame 1 and a saw frame 2. The saw frame 2 is mounted on the sawing machine with adjustable height. A saw blade 3 is mounted on the saw frame 2, and two pulleys are installed on the saw frame 2. The two ends of the saw blade 3 are connected to the pulleys for transmission, and the rotation of the pulleys drives the saw blade 3 to rotate. Two opposing columns are set on the sawing machine, and the saw blade 3 is mounted on the columns with adjustable height. A lifting piston cylinder is installed on the sawing machine, which drives the saw frame 2 to move up and down. The saw frame 2 is set at an angle to facilitate the placement of the saw blade 3 and prevent interference between the saw frame 2 and the bar stock. A conveyor frame 4 is set below the saw frame 2 to load and transport the bar stock. Multiple conveyor rollers 5 are installed at intervals on the conveyor frame 4. There is a chain drive between adjacent conveyor rollers 5. The motor drives the conveyor rollers 5 to rotate, and there is a chain drive between the output shaft of the motor and any one of the conveyor rollers 5. A V-shaped groove 6 is set in the middle of the outer wall of the conveyor roller 5, and the bar stock is supported in the V-shaped groove 6, which is stable and reliable.

[0081] Several spaced-apart feeding and correction mechanisms are installed on the conveyor frame 4. In this embodiment, two feeding and correction mechanisms are provided. Each feeding and correction mechanism includes two oppositely arranged feeding clamps 33, which are slidably disposed. Correction screws 34 and sliding rods 35 corresponding to the feeding clamps 33 are installed on the conveyor frame 4. The correction screws 34 are threadedly connected to the feeding clamps 33, and the sliding rods 35 are slidably inserted into the feeding clamps 33. A chain drive is established between the correction screws 34 of the two feeding and correction mechanisms, and the correction screws 34 are driven by a motor. A correction head 36 is installed on the feeding clamp 33, with a pad 37 at the end of the correction head 36. A buffer spring 38 is installed between the correction head 36 and the feeding clamp 33. The correction head 36 clamps and corrects the bar stock. A buffer chamber 39 is provided on the feeding clamp 33. One end of the correction head 36 is adapted to be installed in the buffer chamber 39. The buffer spring 38 is installed in the buffer chamber 39. The buffer chamber 39 is connected to the liquid storage tank through the flow pipe. A solenoid valve 40 is installed on the flow pipe. A position sensor 41 is installed on the conveyor frame 4. After the position sensor 41 detects that the feeding clamp 33 has slid into place, the solenoid valve 40 closes.

[0082] After the bar stock is loaded onto the conveyor frame 4, the two opposing loading clamps 33 move closer to each other, causing the correction head 36 to clamp the bar stock, thus achieving the correction and positioning of the bar stock. A buffer spring 38 is installed between the correction head 36 and the loading clamp 33. In the initial stage when the correction head 36 clamps the bar stock, it can buffer the movement and avoid damage to the surface of the bar stock from hard contact. The buffer chamber 39 is filled with buffer solution. During the process of the correction head 36 compressing the buffer spring 38, the buffer solution is squeezed out of the buffer chamber 39 into the storage tank. After the position sensor 41 detects that the loading clamp 33 has slid into place, the solenoid valve 40 closes, and the buffer chamber 39 is closed, thereby achieving the positioning of the correction head 36 and preventing it from moving. At this time, the correction head 36 completes the correction and positioning of the bar stock, ensuring the accuracy of the bar stock loading position. After the correction is completed, the loading clamp 33 returns to its original position, and the solenoid valve 40 opens, causing the correction head 36 to return to its original position so as to correct the loading of the next bar.

[0083] A clamping and pushing mechanism is installed on the sawing machine. The clamping and pushing mechanism includes two front clamps 7 and two rear clamps 8, which clamp and position the bar stock respectively. The two front clamps 7 are placed on the left and right sides of the conveyor frame 4, and the two rear clamps 8 are placed on the left and right sides of the conveyor frame 4. The sawing machine is equipped with front slides 9 and rear slides 10 that can move back and forth. The saw frame 2 is placed between the front slides 9 and rear slides 10. The two front clamps 7 are mounted on the front slides 9 and the two rear clamps 8 are mounted on the rear slides 10 and the two rear clamps 8 are mounted on the rear slides 10.

[0084] Two front clamps 7 are respectively installed on the left and right sides of the front slide 9. A front screw and two front slide rails corresponding to the front slide 9 are installed on the saw. The front screw is driven by a motor. The front slide 9 is threadedly fitted with the front screw and slidably connected to the two front slide rails. The rotation of the front screw realizes the forward and backward movement of the front slide 9. A front piston cylinder corresponding to the front clamp 7 is installed on the front slide 9, and the telescopic rod of the front piston cylinder is connected to the front clamp 7.

[0085] Two rear clamps 8 are respectively installed on the left and right sides of the rear slide 10. A rear screw and two rear slide rails corresponding to the rear slide 10 are installed on the saw. The rear screw is driven by a motor. The rear slide 10 is threadedly fitted with the rear screw and slidably connected to the two rear slide rails. The rotation of the rear screw enables the rear slide 10 to move back and forth. A rear piston cylinder corresponding to the rear clamp 8 is installed on the rear slide 10, and the extension rod of the rear piston cylinder is connected to the rear clamp 8.

[0086] Both the front clamp 7 and the rear clamp 8 are equipped with clamping blocks 42 and preload springs 43. The preload springs 43 abut against the clamping blocks 42, which are slidably disposed. Both the front clamp 7 and the rear clamp 8 are provided with mounting grooves, and the clamping blocks 42 are fitted with mounting grooves. One end of the preload spring 43 is connected to the bottom surface of the mounting groove, and the other end of the preload spring 43 is connected to the clamping blocks 42. The end of the clamping blocks 42 is provided with a protruding edge 44. Both the front clamp 7 and the rear clamp 8 are hinged to turntables 45, which are connected to pressure arms 46. Pressure blocks 47 that can buffer deformation are connected to the pressure arms 46. A gear ring 48 is provided on the turntable 45, and a rack 49 is provided on the clamping blocks 42. The rack 49 meshes with the gear ring 48 for transmission. The clamping blocks 42 clamp the bar, and the pressure blocks 47 press on the bar.

[0087] During the clamping process of the front clamp 7 and rear clamp 8, the clamping block 42 first contacts the bar. As the two front clamps 7 or the two rear clamps 8 approach each other, the clamping block 42 moves towards the preload spring 43, thereby driving the turntable 45 to rotate through the meshing transmission of the rack 49 and the gear ring 48. The clamping arm 46 rotates together with the turntable 45. When the clamping block 42 moves to the locking position, the rear protrusion 44 presses against the end face of the front clamp 7 or the rear clamp 8, and the bar is clamped in place. The pressure block 47 presses firmly onto the bar. Through this structural design, not only is the clamping and positioning of the bar achieved, but also the pressing and positioning of the bar is achieved. This dual approach prevents the bar from swaying vertically during the sawing process, ensuring the sawing effect.

[0088] A vertical distance sensor 11 facing downwards is installed on the saw frame 2, and a horizontal distance sensor 12 facing the end face of the bar is installed on the conveyor frame 4; the horizontal distance sensor 12 is installed at the end of the conveyor frame 4. A detection mechanism is set in front of the conveyor frame 4, and the sawn bar is transferred to the detection mechanism for detection.

[0089] The testing mechanism includes a testing frame 13 and a support frame 14. A load cell 15 is installed between the support frame 14 and the testing frame 13. The load cell 15 is fixedly mounted on the testing frame 13, and the support frame 14 is supported on the load cell 15. Distance sensors 16 are installed at both ends of the support frame 14. A laser marking device 17 is installed on the testing frame 13. U-shaped positioning seats 18 are provided at both ends of the support frame 14, with the openings of the two positioning seats 18 facing each other. A recessed V-shaped support groove 19 is provided on the upper surface of the support frame 14. The support frame 14 includes a base plate 20 and a top plate 21, with several spaced vertical plates 22 connecting the base plate 20 and the top plate 21. The support groove 19 is provided on the top plate 21. Windows 23 are provided on the positioning seats 18, and the two distance sensors 16 are respectively positioned facing the two windows 23. The laser emitted by the laser marking device 17 passes through the windows 23 and illuminates the end face of the bar.

[0090] A lifting pusher 24 is installed on the inspection frame 13, and two opposing inspection clamps 25 are installed on the support frame 14. A return spring 26 is installed between the inspection clamps 25 and the support frame 14. When the lifting pusher 24 rises, it pushes the two inspection clamps 25 closer together to clamp and correct the deviation of the bar. When the lifting pusher 24 falls, it separates from the inspection clamps 25. A detachable clamping plate 27 is provided on the opposite surface of the inspection clamps 25, and the bar is clamped and corrected by the clamping plate 27. A detection piston cylinder 28 is installed on the detection frame 13. A lifting push block 24 is connected to the telescopic rod of the detection piston cylinder 28. The lifting push block 24 has a pushing surface 29 that is inclined from top to bottom and outward on both sides. An extension rod 30 is provided on the detection clamp 25. The extension rods 30 on the two detection clamps 25 are staggered. A push column 31 is connected to the extension rod 30. The push column 31 abuts against the pushing surface 29. A guide rail 32 is provided on the support frame 14. The bottom of the detection clamp 25 is slidably connected to the guide rail 32. An avoidance groove is provided on the top plate 21. The detection clamp 25 passes through the avoidance groove.

[0091] After the sawn bars are loaded onto the support frame 14, the lifting push block 24 rises, causing the two pushing surfaces 29 to abut against the push column 31. This pushes the two detection clamps 25 to move closer to each other, clamping and correcting the bar. After correction, the length of the bar is measured to ensure the accuracy of the length measurement. When measuring the weight of the bar, the lifting push block 24 moves downward and separates from the detection clamps 25 to prevent the lifting push block 24 from affecting the measurement data.

[0092] A sawing method using an integrated sawing machine to saw bars includes the following steps: S1, loading the bars onto a conveyor frame 4, which pushes the bars forward. A gripper on a robotic arm picks up the bars and transfers them onto the conveyor frame 4. Conveying rollers 5 on the conveyor frame 4 support the bars. Two opposing loading clamps 33 move towards each other, causing a correction head 36 to clamp the bars, achieving correction and positioning. After correction, the loading clamps 33 return to their original position, and a solenoid valve 40 opens, causing the correction head 36 to return to its original position for loading and correction of the next bar. A motor drives the conveyor rollers 5 to rotate, thus conveying the bars forward.

[0093] S2, the vertical distance sensor 11 detects that the bar is in place in the vertical direction, and then the horizontal distance sensor 12 detects the distance to the front end of the bar for secondary confirmation of the position; at this time, the starting position of the end of the bar is determined.

[0094] S3, the two rear clamps 8 approach each other to clamp the bar and move forward through the rear slide 10 to push the bar forward. The pushing distance is determined according to the required sawing length.

[0095] S4, the bar is pushed into place, and the two front clamps 7 move closer to each other to clamp and position the bar; at this time, both the two front clamps 7 and the two rear clamps 8 clamp and position the bar, ensuring the stability of sawing.

[0096] S5, the saw frame 2 moves downward to saw the bar. The vertical distance sensor 11 detects the distance between the saw frame 2 and the bar. Before the saw blade 3 approaches the bar, the saw frame 2 moves downward quickly; after the saw blade 3 approaches the bar, the saw frame 2 moves downward slowly to saw the bar. The saw frame 2 descends quickly before the saw blade 3 approaches the bar, thus accelerating the sawing process and improving work efficiency.

[0097] S6, after sawing, the front clamp 7 clamps the bar and moves forward. Once in position, the front clamp 7 is released and returns to its original position. Simultaneously, the rear clamp 8 is released and moves backward to its original position. The robotic arm transfers the sawn bar to the inspection mechanism for inspection. During inspection, the weight of the bar is detected by the weighing sensor 15. Distance sensors 16 installed at both ends of the support frame 14 detect the distance between the two ends of the bar, thereby calculating the length of the bar. During weight measurement, the lifting push block 24 descends to its low position, separating the pushing surface 29 on the lifting push block 24 from the push column 31. Before length measurement, the lifting push block 24 rises, causing the two pushing surfaces 29 to abut against the push column 31, thereby pushing the two inspection clamps 25 to move closer to each other, clamping and correcting the bar. After correction, the length of the bar is measured to ensure the accuracy of the length detection. The information of the bar is laser-printed onto the surface of the bar by the laser marking machine. After inspection, the robotic arm transfers the bar from the support frame 14 to the unloading station for storage.

[0098] S7, repeat S3 to S6.

[0099] The entire sawing process for the bar is completed automatically. The bar is conveyed with secondary positioning confirmation, improving the accuracy of the bar's position and thus the precision of the sawing length. The robotic arm transfers the sawn bars to the inspection mechanism for testing. The inspection operation is convenient, reducing workload and improving work efficiency. Before the saw blade 3 approaches the bar, the saw frame 2 descends rapidly, accelerating the sawing pace and further improving work efficiency.

The vertical distance sensor detects the bar's arrival, and the horizontal distance sensor detects the distance to the front end of the bar for secondary confirmation. S3. The two rear clamps clamp the bar and push it forward. S4. Once the bar is in place, the two front clamps hold and position it. S5. The saw frame moves downward to saw the bar. S6. After sawing, the front clamps hold the bar and move it forward. Once in place, the front clamps release and return to their original positions. The rear clamps release and move backward to their original positions. The robotic arm transfers the sawn bar to the inspection mechanism for inspection. S7. Repeat S3 to S6.

10. The sawing method of the integrated sawing machine according to claim 9, characterized in that, In S5, the vertical distance sensor detects the distance between the saw blade and the bar. Before the saw blade approaches the bar, the saw frame moves downward quickly. After the saw blade approaches the bar, the saw frame moves downward slowly to saw the bar.
