Description

Technical Field

[0001] The present invention relates to the technical field of sawing processing production lines, and specifically relates to a sawing automatic processing production line and a processing method thereof. Background Art

[0002] Sawing is a cutting process that uses a handsaw or a semi-automatic sawing machine to cut workpieces or materials. The working range of sawing includes: dividing various materials or semi-finished products, sawing off the excess parts on the workpieces, sawing grooves on the workpieces, etc.

[0003] When the existing processing production line is in use, workers need to move the workpiece to the platform and place it horizontally. After manually moving it to the platform, it needs to be moved and adjusted to the processing position of the sawing machine. The above solution uses manual handling and has the following problems: During the cutting process, the circular sawing machine will clamp at the cutting end. Since the workpiece is relatively long, it cannot be firmly clamped and limited only through the end, resulting in the swing of the workpiece. Secondly, after the cutting is completed, workers still need to move the 6-meter-long workpiece to the cutting position again, causing fatigue in cutting. Summary of the Invention

Since the workpiece is relatively long, it cannot be firmly clamped and limited only through the end, resulting in the swing of the workpiece. Secondly, after the cutting is completed, workers still need to move the 6-meter-long workpiece to the cutting position again, causing fatigue in cutting.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A sawing automatic processing production line and a processing method thereof, including: a ball platform and a circular sawing machine. A plurality of mounting seats are fixedly connected to the upper end of the ball platform. Ball bearings are rotatably connected inside the mounting seats.

PLC control systems are fixedly connected inside the first conveying tooling brackets and the second conveying tooling brackets. Mounting plates are fixedly connected to one side of the first conveying tooling brackets and the second conveying tooling brackets. A circular sawing machine is fixedly connected to one end of the ball platform. L-shaped support frames are fixedly connected to both ends at the rear side of the ball platform.

[0013] Preferably, workpieces being processed and workpieces to be processed are arranged above the reciprocating conveying chain.

[0014] A processing method for a sawing automatic processing production line includes the following specific processing methods:

[0015] Step 1: Turn on the equipment for startup work. After startup, control the first servo motor and the second servo motor to start through the PLC control system. The first servo motor and the second servo motor drive the reciprocating conveying chain to start running. The PLC control system can control the running time of the first servo motor and the second servo motor. After the photoelectric switch senses the workpiece, the reciprocating conveying chain stops running;

[0016] Step 2: Drive the driving motor. After driving, drive the rubber wheel to rotate. After rotation, rubber friction can be provided to the workpiece to realize the conveying of the workpiece. Since the lower surface of the workpiece is supported by ball bearings, the rubber wheel only needs to provide a little friction to complete the conveying function. After conveying, the circular saw machine starts cutting. When cutting the last workpiece, the photoelectric switch senses that there is no workpiece on the platform. At this time, a signal is transmitted to the PLC control system;

[0017] Step 3: The PLC control system sends signals to the first servo motor and the second servo motor again, thereby driving the operation again. The driving sprocket rotates, and the driving sprocket drives the driven sprocket to rotate through the transmission chain. The driven sprocket drives the reciprocating conveying chain to rotate, thereby driving the workpiece to be conveyed. After the photoelectric switch senses the workpiece, the reciprocating conveying chain stops running again;

[0018] Step 4: Subsequently, the driving motor conveys the workpiece again to facilitate the cutting work of the circular sawing machine. During the cutting process, the electric telescopic rod descends, and then is engaged with the workpiece through the concave clamping seat, which can ensure that there is no swing or position deviation during the cutting process.

[0019] (III) Beneficial effects

[0020] The present invention provides a sawing automatic processing production line and its processing method, having the following beneficial effects:

[0021] 1. In the present invention, by providing an electric telescopic rod, a concave clamping seat and a driving motor, during the cutting process, the electric telescopic rod descends, and then is engaged with the workpiece through the concave clamping seat, which can ensure that there is no swing or position deviation during the cutting process. When the position needs to be moved, the electric telescopic rod extends upward to release the concave clamping seat, and the driving motor drives, driving the rubber wheel to rotate. After rotation, it can provide rubber friction to the workpiece to realize the conveyance of the workpiece. It is controlled by a servo motor, PLC, photoelectric induction switch, etc., and automatically stops running after turning to the designated position. After the workpiece processing is completed, the next workpiece automatically starts to turn.

[0022] 2. In the present invention, when sawing the previous workpiece, the next workpiece to be processed has automatically turned to the area to be processed, without the need to stop the machine and wait, and the processing efficiency is high.

[0023] 3. In the present invention, when the workpiece is placed on the platform to be processed, the workpiece has been adjusted in the processing direction and does not require secondary adjustment.

[0033] Embodiment 1:

[0034] As Figures 1-6As shown in the figure, an embodiment of the present invention provides a sawing automatic processing production line and its processing method, including: a ball platform 1 and a circular sawing machine 3. A plurality of mounting seats 18 are fixedly connected to the upper end of the ball platform 1. A ball 19 is rotatably connected inside the mounting seat 18. Since the lower surface of the workpiece is supported by the ball 19, the rubber wheel 24 only needs to provide a little friction to complete the conveying function. A first conveying tooling bracket 5 and a second conveying tooling bracket 6 are respectively arranged on both sides of the ball platform 1. A PLC control system 7 is fixedly connected inside both the first conveying tooling bracket 5 and the second conveying tooling bracket 6. By controlling the PLC control system 7, the first servo motor 9 and the second servo motor 11 are started. The first servo motor 9 and the second servo motor 11 drive the reciprocating conveying chain 15 to start running. A mounting plate 10 is fixedly connected to one side of both the first conveying tooling bracket 5 and the second conveying tooling bracket 6. A circular sawing machine 3 is fixedly connected to one end of the ball platform 1. The circular sawing machine 3 starts cutting. When cutting the last workpiece, the photoelectric switch 17 senses that there is no workpiece on the platform. At this time, a signal is transmitted to the PLC control system 7. L-shaped support frames 20 are fixedly connected to both ends at the rear side of the ball platform 1. An electric telescopic rod 21 is fixedly connected to the front side of the top of the L-shaped support frame 20. The electric telescopic rod 21 descends, and then is engaged with the workpiece through the concave clamping seat 22, which can ensure that there is no swing or position deviation during the cutting process. The extended end of the electric telescopic rod 21 is fixedly connected to the concave clamping seat 22. A driving motor 23 is fixedly connected to one side end of the ball platform 1 close to the L-shaped support frame 20. Driven by the driving motor 23, the rubber wheel 24 rotates. After rotation, it can provide rubber friction to the workpiece to realize the conveying of the workpiece. The driving end of the driving motor 23 is fixedly connected to the rubber wheel 24. A photoelectric switch 17 is arranged at the end of the second conveying tooling bracket 6 close to the first servo motor 9. The PLC control system 7 can control the running time of the first servo motor 9 and the second servo motor 11. When the photoelectric switch 17 senses the workpiece, the reciprocating conveying chain 15 stops running. Two photoelectric switches 17 are arranged at the end of the second conveying tooling bracket 6 far from the first servo motor 9.

[0035] On one side of the second conveying tooling bracket 6, there is a fixed connection with an installation box 8. Inside the installation box 8, there is a fixed connection with a first servo motor 9. On one side of the mounting plate 10 of the first conveying tooling bracket 5, there is a fixed connection with a second servo motor 11. The output shafts of the first servo motor 9 and the second servo motor 11 are both fixedly connected with a driving sprocket 12. When the driving sprocket 12 rotates, the driving sprocket 12 drives a driven sprocket 13 to rotate through a transmission chain 14. The driven sprocket 13 drives a reciprocating conveying chain 15 to rotate, thereby driving the workpiece 4 to be conveyed. On one side of both mounting plates 10, there is a rotatably connected driven sprocket 13. The surfaces of two groups of driving sprockets 12 and driven sprockets 13 are both engaged with a transmission chain 14. Inside both the first conveying tooling bracket 5 and the second conveying tooling bracket 6, there is a reciprocating conveying chain 15. Above the reciprocating conveying chain 15, there are workpieces 2 being processed and workpieces 4 to be processed. One side of the driven sprocket 13 is fixedly connected with the sprocket of the reciprocating conveying chain 15. On the outer sidewall of the reciprocating conveying chain 15, there are fixedly connected several material pushing blocks 16. On the upper ends of both the first conveying tooling bracket 5 and the second conveying tooling bracket 6, there are fixedly connected several photoelectric switches 17. At the four corners of the lower ends of both the first conveying tooling bracket 5 and the second conveying tooling bracket 6, there are fixedly connected support feet. Near the second servo motor 11 end of the first conveying tooling bracket 5, there is a photoelectric switch 17. After the photoelectric switch 17 senses the workpiece, the reciprocating conveying chain 15 stops running again. At the end of the first conveying tooling bracket 5 far from the second servo motor 11, there are two photoelectric switches 17.

[0036] Embodiment 2:

[0037] The difference between this embodiment and Embodiment 1 lies in: A sawing automatic processing production line processing method, including the following specific processing methods:

[0038] Step 1: Turn on the equipment and start it. After starting, control the first servo motor 9 and the second servo motor 11 to start through the PLC control system 7. The first servo motor 9 and the second servo motor 11 drive the reciprocating conveying chain 15 to start running. The PLC control system 7 can control the running time of the first servo motor 9 and the second servo motor 11. After the photoelectric switch 17 senses the workpiece, the reciprocating conveying chain 15 stops running;

[0039] Step 2: Drive the driving motor 23. After driving, it drives the rubber wheel 24 to rotate. After rotation, it can provide rubber friction to the workpiece to realize the conveying of the workpiece. And because the lower surface of the workpiece is supported by the balls 19, the rubber wheel 24 only needs to provide a little friction force to complete the conveying function. After conveying, the circular saw machine 3 starts cutting. When cutting the last workpiece, the photoelectric switch 17 senses that there is no workpiece on the platform. At this time, it transmits a signal to the PLC control system 7;

[0040] Step 3: The PLC control system 7 sends signals to the first servo motor 9 and the second servo motor 11 again, thereby driving the operation again. The driving sprocket 12 rotates, and the driving sprocket 12 drives the driven sprocket 13 to rotate through the transmission chain 14. The driven sprocket 13 drives the reciprocating conveying chain 15 to rotate, thereby driving the workpiece 4 to be conveyed. After the photoelectric switch 17 senses the workpiece, the reciprocating conveying chain 15 stops operating again;

[0041] Step 4: Subsequently, the driving motor 23 conveys the workpiece again to facilitate the cutting work of the circular sawing machine 3. During the cutting process, the electric telescopic rod 21 descends, and then is clamped with the workpiece through the concave clamping seat 22, so as to ensure that there will be no swing or position deviation during the cutting process.
