If the specific posture changes, the directional indication will also change accordingly.

[0030] The existing hollow anchor production line has a low degree of automation, and the loading and unloading and handling processes between each process are still carried out manually, resulting in low production efficiency. In addition, the hollow anchor needs to be heated to 500 to 1200 degrees before the thread rolling process, so that the temperature of the hollow anchor reaches above the plastic deformation temperature, so as to form the desired shape during the thread rolling process. When the thread rolling wheel of the thread rolling machine is in direct contact with the high temperature hollow anchor for a long time, the temperature of the thread rolling wheel will be too high, which will not only affect the thread rolling process quality, but also affect the service life of the thread rolling wheel.

[0032] See also Figure 1 , hollow anchor 100 along Figure 1 The feed roller table 200, the thread rolling machine 1, the discharge roller table 300 and the fixed length roller table 600 are arranged in sequence along the front-to-back direction. Figure 1The left and right directions in the drawing are divided into a stacking part, a connecting part and a feeding part. The stacking part is used to store the hollow anchor rods 100. The height of the feeding part is slightly lower than that of the stacking part. The connecting part is inclined and connected between the stacking part and the feeding part. A pushing assembly is provided on the side of the stacking part away from the feeding part. The pushing assembly is used to push the hollow anchor rods 100 in the stacking part to the feeding part. The rear end of the feeding part is aligned with the feeding port 12 of the thread rolling machine 1. The feeding part is provided with a high-frequency heating machine. When the high-frequency heating machine heats the hollow anchor rods 100 on the feeding part to a preset temperature, the feeding part conveys the hollow anchor rods 100 into the thread rolling machine 1, so that the thread rolling machine 1 performs thread rolling on the heated hollow anchor rods 100. The discharge roller table 300 is aligned with the discharge port 11 of the thread rolling machine 1, and the hollow anchor rods 100 after the thread rolling process are conveyed to the discharge roller table 300. The cutting frame 400 is arranged on one side of the discharging roller table 300 along the left-right direction, and the height of the cutting frame 400 is slightly lower than that of the discharging roller table 300. The discharging roller table 300 is provided with a turning rod 303 to push the hollow anchor rod 100 on the discharging roller table 300 toward the cutting frame 400. The cutting frame 400 is arranged in alignment with the cutting machine 500. The cutting frame 400 is used to convey the hollow anchor rod 100 placed thereon toward the fixed-length roller table 600. The cutting machine 500 is arranged between the cutting frame 400 and the fixed-length roller table 600. The fixed-length roller table 600 is provided with a fixed-length limiting mechanism. The fixed-length limiting mechanism is controlled according to the preset size to limit the hollow anchor rod 100, and then the hollow anchor rod 100 is cut according to the preset size by the cutting machine 500. The cut hollow anchor rod 100 is placed on a cut-to-length roller table 600 and is marked and printed thereon by a laser marking machine. Finally, the cut-to-length roller table 600 transports the marked hollow anchor rod 100 to a finished product collection rack 700 for storage, thereby realizing the production of the hollow anchor rod 100.

[0033] It should be noted that when the thread rolling machine 1 performs thread rolling on the hollow anchor rod 100, the thread rolling wheel 13 of the thread rolling machine 1 is in direct contact with the high-temperature hollow anchor rod 100. The thread rolling wheel 13 is cooled by the cooling system 20 on the thread rolling machine 1 so that the temperature of the thread rolling wheel 13 is not too high during the long-term thread rolling process, thereby ensuring the quality of the thread rolling process.

[0034] The hollow anchor rod production line proposed in the present invention realizes the automatic connection of the processes of feeding, thread rolling, cutting, marking and discharging of the hollow anchor rod 100 by integrating the feed roller table 200, the thread rolling machine 1, the discharging roller table 300, the cutting frame 400, the cutting machine 500, the length roller table 600, the high-frequency heating machine, the laser marking machine and the finished product collection frame 700, without the need for manual participation, with a high degree of automation, effectively improving production efficiency and reducing labor costs. During the thread rolling process of the thread rolling machine 1, the cooling system 20 can cool the thread rolling wheel 13 so that the temperature of the thread rolling wheel 13 is not too high during the thread rolling process of the hollow anchor rod 100, thereby ensuring the thread rolling process quality and extending the service life of the thread rolling wheel 13.

[0035] In one embodiment, the cooling system 20 includes a water tank 21, a circulation pipe 22, a water pump and a plurality of spray nozzles 23. The water tank 21 is disposed at the bottom of the thread rolling machine body 10. A water storage chamber for accommodating cooling water is formed in the water tank 21. Both ends of the circulation pipe 22 are connected to the water storage chamber. The water pump is used to pump the cooling water in the water storage chamber to circulate in the water storage chamber and the circulation pipe 22. A spray nozzle 23 is disposed between any two adjacent thread rolling wheels 13, and each spray nozzle 23 is connected to the circulation pipe 22.

[0036] See also Figure 6 The cooling system 20 is arranged in the thread rolling machine body 10, and the spray nozzle 23 is connected to the circulation pipe 22 and extends between two adjacent thread rolling wheels 13. The water pump draws cooling water from the water tank 21 and transports it to each spray nozzle 23 in turn through the circulation pipe 22. Each spray nozzle 23 sprays the cooling water evenly on the thread rolling wheels 13 adjacent to it, so that the cooling of multiple thread rolling wheels 13 is achieved through multiple spray nozzles 23, so that the temperature of the thread rolling wheels 13 is not too high during the thread rolling process of the hollow anchor rod 100, thereby ensuring the thread rolling process quality. In addition, the cooling water can lubricate the thread rolling wheel 13, reduce the wear of the thread rolling wheel 13 and the hollow anchor rod 100, and effectively extend the service life of the thread rolling wheel 13. The spray nozzle 23 forms a water mist of cooling water to spray the thread rolling wheel 13 to avoid splashing of cooling water. It can be understood that the water tank 21 is used to contain cooling water for circulation. The water tank 21 is directly connected to an external water source through a water inlet pipe, so as to ensure that the cooling water in the water tank 21 can be replenished in time, thereby ensuring the continuous and effective operation of the cooling system 20 .

[0037] In one embodiment, a liquid level sensor is provided in the water tank 21, and the liquid level sensor is used to monitor the cooling water in the water tank 21 in real time. The liquid level sensor is communicatively connected to the electric control box, and the electric control box can control the water supply of the external water source to the water tank 21 according to the liquid level information provided by the liquid level sensor, so as to ensure that the cooling water in the water tank 21 can be replenished in time. By providing the liquid level sensor, it is convenient to accurately control the cooling water in the water tank 21, and improve the automation and intelligence of the cooling system 20.

[0038] In one embodiment, a processing channel 14 for the hollow anchor rod 100 to pass through is opened on the thread rolling machine body 10 , a feed port 12 and a discharge port 11 are formed on both sides of the processing channel 14 , and each thread rolling wheel 13 and each spray nozzle 23 are installed on the inner wall of the processing channel 14 .

[0039] See also Figure 2 and Figure 3, a processing channel 14 is provided in the middle of the thread rolling machine body 10, and the hollow anchor rod 100 enters the processing channel 14 from the feed port 12, and is thread-rolled by multiple thread rolling wheels 13 in the processing channel 14, and then is discharged from the processing channel 14 from the discharge port 11 and transported to the discharge roller table 300. It can be explained that a thread rolling seat 15 is provided in the processing channel 14 corresponding to each thread rolling wheel 13, and each thread rolling wheel 13 is rotatably mounted on the corresponding thread rolling seat 15. Each thread rolling seat 15 is installed on the inner wall of the processing channel 14, and the two ends of the thread rolling wheel 13 are rotatably connected to the two sides of the thread rolling seat 15, so that the thread rolling wheel 13 is rollingly installed on the thread rolling seat 15. The thread rolling seat 15 is provided to provide support for the thread rolling wheel 13, so that the thread rolling wheel 13 can rotate relative to the thread rolling seat 15, so as to perform thread rolling processing on the hollow anchor rod 100.

[0040] In one embodiment, the thread rolling machine 1 also includes a clamping seat 30, which is arranged on the side of the thread rolling machine 1 facing the discharge port 11. The clamping seat 30 is rotatably connected to a plurality of mutually spaced positioning wheels 31. The plurality of positioning wheels 31 enclose a positioning channel 32 aligned with the processing channel 14, and the plurality of positioning wheels 31 are used to clamp the hollow anchor rod 100 in the positioning channel 32.

[0041] See also Figure 4 and Figure 5 , multiple positioning wheels 31 are arranged at intervals to form a positioning channel 32, and the positioning channel 32 is aligned with the processing channel 14, so that the hollow anchor rod 100 can pass through the positioning channel 32 and the processing channel 14 in sequence. Each positioning wheel 31 is rotatably mounted on the clamping seat 30. During the feeding and discharging process of the hollow anchor rod 100, each positioning wheel 31 rolls with the hollow anchor rod 100, so that the hollow anchor rod 100 can slide relative to the clamping seat 30 while aligning with the processing channel 14; when the hollow anchor rod 100 is in the thread rolling process, by fixing each positioning wheel 31, the positioning wheel 31 and the hollow anchor rod 100 do not roll, so that the hollow anchor rod 100 is clamped and fixed by multiple positioning wheels 31, ensuring that the hollow anchor rod 100 remains stable during the processing.

[0042] In one embodiment, a chip groove 16 and a baffle 17 are provided on the thread rolling machine body 10. The chip groove 16 and the baffle 17 are both located on the side of the thread rolling machine body 10 facing the feed port 12. The chip groove 16 is located below the processing channel 14, and the baffle 17 is located above the chip groove 16.

[0043] See also Figure 4The chip groove 16 is connected to the rear side of the three-axis thread rolling machine body 10 and is located below the feed port 12, and the notch of the chip groove 16 is set upward, the chip groove 16 extends in the left-right direction, and the length of the chip groove 16 is greater than the width of the processing channel 14 in the left-right direction, so as to cover the processing channel 14. The chip groove 16 is used to collect the debris dropped when the hollow anchor rod 100 is threaded in the processing channel 14, so as to collect and clean the debris. The baffle 17 is connected to the rear side of the three-axis thread rolling machine body 10 and is located above the feed port 12, and the baffle 17 extends toward the rear side, and the baffle 17 is used to block the debris splashed during the thread rolling process of the hollow anchor rod 100. The baffle 17 is located above the chip groove 16, so that the blocked debris can fall into the chip groove 16, so as to collect and clean the debris. It should be noted that the baffle 17 can be made of a transparent material to facilitate observation of the processing conditions in the processing channel 14 .

[0044] In one embodiment, the discharge roller platform 300 includes a platform body 301, a transport wheel 302 and a flip rod 303. The transport wheel 302 is installed on the top of the platform body 301. The upper surface of the transport wheel 302 forms a transport platform for transporting the hollow anchor rod 100. The flip rod 303 is rotatably connected to one side of the platform body 301. The flip rod 303 is used to flip the hollow anchor rod 100 on the transport platform onto the cutting frame 400.

[0045] It can be explained that the platform 301 provides an installation platform for the transport wheel 302 and the turning rod 303. The transport wheel 302 is installed on the top of the platform 301, and its upper surface forms a transport platform. The transport platform can carry the hollow anchor rod 100 after thread rolling and transport the hollow anchor rod 100 to the rear, ensuring that the hollow anchor rod 100 can be smoothly output from the discharge port 11 of the thread rolling machine 1. The design of the transport wheel 302 ensures the smooth movement of the hollow anchor rod 100 on the discharge roller platform 300. The cutting frame 400 is located on one side of the transport platform. When the hollow anchor rod 100 is placed on the transport platform, the flip rod 303 is located below the hollow anchor rod 100. By rotating the flip rod 303, the flip rod 303 lifts the hollow anchor rod 100 and moves the hollow anchor rod 100 to the cutting frame 400 under the action of gravity, thereby completing the automated flipping of the hollow anchor rod 100 from the discharge roller table 300 to the cutting frame 400, thereby improving the automation level of the hollow anchor rod production line.

[0046] In one embodiment, the discharging roller platform 300 also includes a baffle 304 and a pressure plate 305. The baffle 304 is U-shaped, connected to the top of the platform body 301 and extending upward, and the two sides of the baffle 304 are respectively located on the two sides of the transport platform, and the pressure plate 305 is located above the transport platform. The pressure plate 305 cooperates with the baffle 304 to block the hollow anchor rod 100 on the transport platform.

[0047] See also Figure 7The retaining frame 304 is U-shaped and has an opening facing upward. When the hollow anchor rod 100 is placed on the transport platform, the two sides of the U-shaped frame are respectively located on the left and right sides of the transport platform to prevent the hollow anchor rod 100 from sliding out of the transport platform from the left and right sides, ensuring that the hollow anchor rod 100 is transported in the front-back direction. The pressing plate 305 is located above the transport platform, and the distance between the pressing plate 305 and the transport platform is greater than the diameter of the hollow anchor rod 100 and less than twice the diameter of the hollow anchor rod 100, so that the pressing plate 305 can be used to limit the stacking of multiple hollow anchor rods 100 up and down, and prevent the hollow anchor rod 100 from being stacked too high and sliding out of the transport platform. The retaining frame 304 and the pressing plate 305 cooperate with each other to ensure that the hollow anchor rod 100 is transported smoothly and stably on the transport platform, and prevent the hollow anchor rod 100 from slipping.

[0048] In one embodiment, the two ends of the flip rod 303 are respectively a hinged end and a rotating end, the hinged end is hinged to one side of the table body 301, and the discharge roller table 300 also includes a pushing member 306, which is installed between the table body 301 and the rotating end. The pushing member 306 is used to push the rotating end relative to the hinged end to rotate toward or away from the cutting frame 400.

[0049] Further, the flip rod 303 extends in the left-right direction, the hinged end is located on the side close to the cutting frame 400, and the rotating end is located on the side away from the cutting frame 400. When the hollow anchor rod 100 is placed on the transport platform, the flip rod 303 is located below the hollow anchor rod 100, and the height of the hinged end is higher than the rotating end. When the hollow anchor rod 100 needs to be flipped from the transport platform to the cutting frame 400, the push member 306 is started, so that the push member 306 lifts the rotating end, so that the height of the rotating end is higher than the hinged end, and the flip rod 303 abuts against the hollow anchor rod 100 to lift the hollow anchor rod 100 on the transport platform, and the hollow anchor rod 100 slides toward the cutting frame 400 under the action of gravity, so as to realize the flipping of the hollow anchor rod 100 from the discharge roller platform 300 to the cutting frame 400. When the flipping is completed, the push member 306 can be lowered to reset. It can be explained that the push member 306 can be a pneumatic cylinder or a hydraulic cylinder in the prior art.

[0051] See also Figure 1, the number of the feed roller table 200, the thread rolling machine 1 and the discharge roller table 300 are two, one of the feed roller table 200, the thread rolling machine 1 and the discharge roller table 300 is arranged along the conveying direction of the hollow anchor rod 100 to form a first row, and the other feed roller table 200, the thread rolling machine 1 and the discharge roller table 300 are arranged along the conveying direction of the hollow anchor rod 100 to form another row, and the double row configuration allows two sets of equipment to process the hollow anchor rod 100 at the same time, and the two hollow anchor rods 100 processed by thread rolling can be transported to the cutting rack 400 at the same time, and then cut by the cutting machine 500. The cut hollow anchor rod 100 is transported to the fixed-length roller table 600, and the laser marking machine marks the hollow anchor rod 100 on the fixed-length roller table 600. Finally, the finished product collection rack 700 collects the hollow anchor rods 100 that have completed all processing steps. Through this dual-line parallel operation design, the production line can process more hollow anchor rods 100 in the same time, thereby improving production efficiency. At the same time, since the cutting frame 400 can simultaneously receive two hollow anchor rods 100, the utilization rate of the cutting machine 500 is also improved, thereby reducing the idle time of the equipment.

[0052] In one embodiment, the hollow anchor production line further includes a tailing rack 800 , which is disposed on one side of the cutting rack 400 , and is used to collect the tailings of the hollow anchor 100 after cutting.

[0053] See also Figure 1 The tailing rack 800 is arranged on one side of the cutting rack 400. When the hollow anchor rod 100 is cut by the cutting machine 500 and tailings are generated, the tailings can directly fall onto the tailing rack 800, avoiding the tailings from being scattered in the working area, reducing the cleaning workload, and facilitating the collection of the tailings.
