Description

Technical Field

[0001] This utility model relates to the field of thread rolling machine technology, and in particular to a three-axis thread rolling machine and a hollow anchor bolt production line for hollow anchor bolts. Background Technology

[0002] A thread rolling machine is a multi-functional extrusion forming machine tool. Within its rolling pressure range, it can perform thread rolling, straight knitting, and oblique knitting on workpieces. Currently, thread rolling machines are basically divided into two-axis thread rolling machines and three-axis thread rolling machines, with three-axis thread rolling machines mainly used in the processing of tubular workpieces.

[0003] Before thread rolling hollow anchor bolts, the three-axis thread rolling machine needs to heat the raw material to 500 to 1200 degrees Celsius to ensure it reaches a temperature above the plastic deformation temperature, thus forming the desired shape during the thread rolling process. However, in existing three-axis thread rolling machines, the thread rolling wheels are in direct contact with the hollow anchor bolts. Prolonged processing causes the thread rolling wheels to overheat, which not only affects the thread rolling quality but also shortens the lifespan of the thread rolling wheels. Utility Model Content

[0004] The main purpose of this invention is to propose a three-axis thread rolling machine and a hollow anchor bolt production line, which aims to solve the technical problem that the temperature of the thread rolling wheel of the existing three-axis thread rolling machine increases during long-term processing of hollow anchor bolts, thus affecting the thread rolling quality and the service life of the thread rolling wheel.

[0005] To achieve the above objectives, the present invention proposes a three-axis thread rolling machine for hollow anchor bolts, comprising a three-axis thread rolling machine body and a cooling system. The three-axis thread rolling machine body has a processing channel in the middle, with a discharge port and a feed port formed on both sides of the processing channel. Three thread rolling wheels are installed within the processing channel, and a through hole is formed between the three thread rolling wheels for the hollow anchor bolt to pass through. The cooling system includes a water tank, a circulation pipe, a water pump, and three spray nozzles. The water tank is located at the bottom of the three-axis thread rolling machine body, and a water storage chamber for containing cooling water is formed within the water tank. The circulation pipe is located within the three-axis thread rolling machine body and winds around the processing channel, with both ends of the circulation pipe connected to the water storage chamber. The water pump pumps the cooling water in the water storage chamber to circulate within the water storage chamber and the circulation pipe. A spray nozzle is provided between any two adjacent thread rolling wheels, and each spray nozzle is connected to the circulation pipe.

[0006] In one embodiment, the three-axis thread rolling machine for hollow anchor bolts further includes a clamping seat, which is disposed on the side of the three-axis thread rolling machine facing the discharge port. The clamping seat is provided with a clamping assembly for clamping the hollow anchor bolt to keep the hollow anchor bolt aligned with the through hole.

[0007] In one embodiment, the clamping assembly includes a positioning assembly that forms a positioning channel through which the hollow anchor rod passes. The positioning assembly includes a plurality of positioning wheels spaced circumferentially along the positioning channel. The positioning channel is aligned with the through hole. Each positioning wheel is rotatably mounted on the clamping seat and can roll with the hollow anchor rod.

[0008] In one embodiment, a thread rolling seat is provided in the processing channel corresponding to each of the thread rolling wheels, and each of the thread rolling wheels is rotatably mounted on the corresponding thread rolling seat.

[0009] In one embodiment, the three-axis thread rolling machine body is provided with a chip collection groove on the side facing the feed inlet, and the chip collection groove is located below the processing channel.

[0010] In one embodiment, a baffle is provided on the side of the three-axis thread rolling machine body facing the feed inlet, and the baffle is located above the chip collection groove.

[0011] In one embodiment, the water tank is connected to an external water source via an inlet pipe.

[0012] In one embodiment, a liquid level sensor is installed inside the water tank.

[0013] This utility model also proposes a hollow anchor bolt production line, including a loading platform, a unloading platform, and the aforementioned three-axis thread rolling machine for hollow anchor bolts. The loading platform is located on the side of the three-axis thread rolling machine body facing the feed inlet, and the unloading platform is located on the side of the three-axis thread rolling machine body facing the discharge outlet.

[0014] In one embodiment, a high-frequency heater is provided on the loading platform, and the high-frequency heater is used to heat the hollow anchor rod placed on the loading platform.

[0015] This invention proposes a three-axis thread rolling machine and production line for hollow anchor bolts. By installing spray nozzles between any two adjacent thread rolling wheels and a water tank at the bottom of the machine body, cooling water from the tank is pumped into a circulation pipe. This circulation pipe supplies water to the spray nozzles, which spray water mist onto the thread rolling wheels to cool them down. This prevents the threads from overheating during the thread rolling process on the hollow anchor bolts, thus ensuring the quality of the thread rolling process. Furthermore, the cooling water lubricates the threads, reducing wear between the threads and the hollow anchor bolts and effectively extending their service life. The spray nozzles atomize the cooling water and spray it onto the threads, avoiding splashing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0027] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0028] In this utility model, the descriptions of directions such as "up", "down", "front", "back", "left", and "right" are as follows: Figure 1 , Figure 3 and Figure 4 The directions shown are for reference only and are used to interpret the location. Figure 1 , Figure 3 and Figure 4 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0029] When existing three-axis thread rolling machines process hollow anchor bolts, the thread rolling wheels of the three-axis thread rolling machine are in direct contact with the hollow anchor bolts. Over time, this causes the temperature of the thread rolling wheels to rise. Excessive temperature not only affects the thread rolling quality but also the service life of the thread rolling wheels.

[0030] This utility model proposes a three-axis thread rolling machine for hollow anchor bolts, including a three-axis thread rolling machine body 10 and a cooling system 20. The three-axis thread rolling machine body 10 has a processing channel in the middle, and a discharge port 11 and a feed port 12 are formed on both sides of the processing channel. Three thread rolling wheels 13 are installed in the processing channel, and a through hole 14 for the hollow anchor bolt 100 to pass through is formed between the three thread rolling wheels 13. The cooling system 20 includes a water tank 21, a circulation pipe 22, a water pump and three spray nozzles 23. The water tank 21 is set at the bottom of the three-axis thread rolling machine body 10, and a water storage cavity for holding cooling water is formed in the water tank 21. The circulation pipe 22 is set in the three-axis thread rolling machine body 10 and is wound around the processing channel. Both ends of the circulation pipe 22 are connected to the water storage cavity. The water pump is used to pump the cooling water in the water storage cavity to circulate in the water storage cavity and the circulation pipe 22. A spray nozzle 23 is set between any two adjacent thread rolling wheels 13, and each spray nozzle 23 is connected to the circulation pipe 22.

[0031] Please see Figure 1 and Figure 5 Three thread rolling wheels 13 are arranged in a triangle and together form a through hole 14, which is located in the middle of the processing channel. The hollow anchor rod 100 enters the processing channel through the discharge port 11 in the front-to-back direction and gradually passes through the through hole 14. The three thread rolling wheels 13 in the processing channel perform thread rolling on the hollow anchor rod 100. After processing, it is output through the feed port 12. During this process, a water pump draws cooling water from the water tank 21 and delivers it sequentially to three spray nozzles 23 through the circulation pipe 22. The three spray nozzles 23 are respectively set between two adjacent thread rolling wheels 13. Each spray nozzle 23 sprays cooling water evenly onto the adjacent thread rolling wheel 13, thereby achieving cooling of the three thread rolling wheels 13 through the three spray nozzles 23. It can be understood that the three-axis thread rolling machine proposed in this utility model includes the electrical control box in the prior art, which is used to control the conveying of the hollow anchor rod 100 and supply power to the three-axis thread rolling machine.

[0032] This invention proposes a three-axis thread rolling machine for hollow anchor bolts. By placing spray nozzles 23 between any two adjacent thread rolling wheels 13 and a water tank 21 at the bottom of the machine body 10, cooling water from the tank 21 is pumped into a circulation pipe 22. This circulation pipe supplies water to the spray nozzles 23, which spray water mist onto the thread rolling wheels 13 to cool them down. This prevents the threads from overheating during the thread rolling process on the hollow anchor bolt 100, thus ensuring the quality of the thread rolling process. Furthermore, the cooling water lubricates the threads 13, reducing wear between the threads 13 and the hollow anchor bolt 100 and effectively extending their service life. The spray nozzles 23 spray the cooling water into a mist onto the threads 13, avoiding splashing.

[0033] In one embodiment, the three-axis thread rolling machine for hollow anchor bolts further includes a clamping seat 30, which is disposed on the side of the three-axis thread rolling machine facing the discharge port 11. The clamping seat 30 is provided with a clamping assembly for clamping the hollow anchor bolt 100 to keep the hollow anchor bolt 100 aligned with the through hole 14.

[0034] Please see Figure 4 The clamping seat 30 is fixed to the side of the three-axis thread rolling machine body 10 facing the discharge port 11, i.e., the front side of the three-axis thread rolling machine body 10. The clamping assembly is installed on the clamping seat 30, and the hollow anchor rod 100 can pass through the clamping seat 30 and be clamped in the clamping assembly. When the thread rolling wheel 13 performs thread rolling on the hollow anchor rod 100, the clamping assembly can provide a stable clamping for the hollow anchor rod 100 to ensure that the hollow anchor rod 100 is always located in the through hole 14 during the thread rolling process, preventing the hollow anchor rod 100 from shifting or vibrating, thereby ensuring the processing quality.

[0035] In one embodiment, the clamping assembly includes a positioning assembly that forms a positioning channel 32 through which the hollow anchor rod 100 passes. The positioning assembly includes a plurality of positioning wheels 31 spaced circumferentially along the positioning channel 32. The positioning channel 32 is aligned with the through hole 14. Each positioning wheel 31 is rotatably mounted on the clamping seat 30 and can roll with the hollow anchor rod 100.

[0036] Please see Figure 3Multiple positioning wheels 31 are spaced apart and enclosed to form a positioning channel 32, which is aligned with the through hole 14, allowing the hollow anchor rod 100 to pass through the positioning channel 32 and the through hole 14 sequentially. 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, allowing the hollow anchor rod 100 to slide relative to the clamping seat 30 while aligning with the through hole 14. During the thread rolling process of the hollow anchor rod 100, by fixing each positioning wheel 31, the positioning wheel 31 and the hollow anchor rod 100 do not roll with each other, thereby clamping and fixing the hollow anchor rod 100 by multiple positioning wheels 31, ensuring that the hollow anchor rod 100 remains stable during the processing.

[0037] In one embodiment, a thread rolling seat 15 is provided in the processing channel corresponding to each thread rolling wheel 13, and each thread rolling wheel 13 is rotatably mounted on the corresponding thread rolling seat 15.

[0038] Please see Figure 2 Each thread rolling seat 15 is installed on the inner wall of the processing channel. The two ends of the thread rolling wheel 13 are rotatably connected to both sides of the thread rolling seat 15, allowing the thread rolling wheel 13 to roll and be mounted on the thread rolling seat 15. By providing support to the thread rolling wheel 13 through the thread rolling seat 15, the thread rolling wheel 13 can rotate relative to the thread rolling seat 15 to perform thread rolling processing on the hollow anchor rod 100. It can be noted that the thread rolling processing of the thread rolling wheel 13 is automatically controlled by the electrical control box.

[0039] In one embodiment, a chip collection groove 16 is provided on the side of the three-axis thread rolling machine body 10 facing the feed port 12, and the chip collection groove 16 is located below the processing channel.

[0040] Please see Figure 3 The chip collection groove 16 is connected to the rear side of the three-axis thread rolling machine body 10 and is located below the feed inlet 12. The opening of the chip collection groove 16 faces upward, and the chip collection groove 16 extends in the left-right direction. The length of the chip collection groove 16 is greater than the width of the processing channel in the left-right direction, so as to cover the processing channel. The chip collection groove 16 is used to collect the chips that fall off the hollow anchor rod 100 during the thread rolling process in the processing channel, so as to facilitate the collection and cleaning of the chips.

[0041] In one embodiment, a baffle 17 is also provided on the side of the three-axis thread rolling machine body 10 facing the feed inlet 12, and the baffle 17 is located above the chip collection groove 16.

[0042] Please continue reading. Figure 3The baffle 17 is connected to the rear side of the three-axis thread rolling machine body 10 and is located above the feed inlet 12. The baffle 17 extends rearward and is used to block debris splashed during the thread rolling process of the hollow anchor rod 100. The baffle 17 is located above the chip collection groove 16, allowing the blocked debris to fall into the chip collection groove 16 for easy collection and cleaning. It should be noted that the baffle 17 can be made of transparent material to facilitate observation of the processing conditions within the processing channel.

[0043] In one embodiment, the water tank 21 is connected to an external water source via an inlet pipe. Understandably, the water tank 21 is used to contain cooling water for circulation. The direct connection of the water tank 21 to the external water source via the inlet pipe ensures that the cooling water in the water tank 21 can be replenished in a timely manner, ensuring the continuous and effective operation of the cooling system 20.

[0044] In one embodiment, a liquid level sensor is installed inside the water tank 21.

[0045] Furthermore, a 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 electrical control box, which can control the water supply from the external water source to the water tank 21 based on the liquid level information provided by the liquid level sensor, ensuring that the cooling water in the water tank 21 can be replenished in a timely manner. By setting up a liquid level sensor, it is possible to accurately control the cooling water in the water tank 21, thereby improving the automation and intelligence of the cooling system 20.

[0046] This utility model also proposes a hollow anchor bolt production line, which includes a loading platform, a unloading platform, and a three-axis thread rolling machine for hollow anchor bolts. The specific structure of the three-axis thread rolling machine for hollow anchor bolts is as described in the above embodiments. Since this hollow anchor bolt production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The loading platform is located on the side of the three-axis thread rolling machine body 10 facing the feed inlet 12, and the unloading platform is located on the side of the three-axis thread rolling machine body 10 facing the discharge outlet 11. The hollow anchor bolt production line proposed in this utility model integrates a feeding platform, a three-axis thread rolling machine, and a discharging platform. The feeding platform is located behind the three-axis thread rolling machine, and the discharging platform is located in front of the three-axis thread rolling machine. The feeding platform feeds the hollow anchor bolt 100 into the feed inlet 12. After the three-axis thread rolling machine completes the thread rolling processing of the hollow anchor bolt 100, the hollow anchor bolt 100 is then sent to the discharging platform from the discharge outlet 11, thereby realizing automated processing and loading / unloading.

[0047] In one embodiment, a high-frequency heating machine is provided on the loading platform. The high-frequency heating machine is used to heat the hollow anchor rod 100 placed on the loading platform. The high-frequency heating machine is used to heat the hollow anchor rod 100 to 500 to 1200 degrees Celsius before the thread rolling process, so that the temperature of the hollow anchor rod 100 reaches above the plastic deformation temperature, thereby forming the required shape during the thread rolling process.
