Description

Technical Field

[0001] This invention belongs to the field of seamless tube production conveyor roller technology, specifically relating to conveyor rollers used in seamless tube production. Background Technology

[0002] In the production of seamless tubes, multiple sets of conveyor rollers are needed to transport the tubes to various processing steps to ultimately form seamless tubes. After the tube blank is heated, it needs to be transported to the punching step. Therefore, during the processing of seamless tubes, the conveyor rollers need to be in contact with the high-temperature tube blank for a long time. At this time, the strength of the conveyor rollers is easily degraded due to prolonged contact with the high-temperature tube blank, which increases the wear of the conveyor rollers and reduces their service life.

[0003] In existing technologies, cooling water pipes are mainly installed inside the conveyor rollers to allow for internal heat exchange and cooling, thus preventing excessive heat and increased wear. However, during operation, the water flow rate and discharge speed of the cooling pipes are fixed. Under prolonged conveying operation, although the conveyor rollers can be cooled by water, the temperature gradually increases while the cooling efficiency remains constant. This can lead to the temperature rise rate of the conveyor rollers being faster than the cooling rate, causing the temperature to continue to rise, increasing wear and tear and affecting service life. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a conveyor roller for seamless tube production, which can solve the problem that the temperature of the conveyor roller continues to rise, resulting in increased wear and tear and affecting the service life of the conveyor roller.

[0005] To solve the above problems, the present invention provides a conveying roller for seamless tube production, comprising: a roller body, wherein an inner groove is provided inside the roller body, and through holes are provided on both sides of the roller body, both through holes communicating with the inner groove, and an inlet pipe and an outlet pipe are rotatably connected to the two through holes respectively;

[0006] Guide covers are fixedly connected to the two opposite side walls of the inner tank. A water inlet control mechanism is installed inside the guide cover located at the water outlet pipe to control the water pressure of the inlet.

[0007] A flow diversion mechanism is provided between the two guide covers to control the path of the water flow;

[0008] A flow control component is also installed between the two guide shields to control the flow rate of water.

[0009] Furthermore, the water inlet control mechanism includes a control spring, which is fixedly installed at the center of the corresponding guide cover. A sealing plug is fixedly connected to the end of the control spring, and the end of the sealing plug extends into the water inlet pipe, with its outer circumference fitting against the inner circumference of the water inlet pipe.

[0010] Furthermore, a limiting rod is fixedly connected to the end of the sealing plug away from the water inlet pipe. The end of the limiting rod passes through the center position of the corresponding guide cover side and is slidably connected to the guide cover.

[0011] Furthermore, the drainage mechanism includes a tube column, which is fixedly connected between two guide covers. A gap is left between the outer periphery of the tube column and the inner periphery of the inner groove. A number of water inlet holes are opened on the side of the guide cover near the water inlet pipe, and a drainage groove is opened on the inner periphery edge of the guide cover near the water outlet pipe.

[0012] Furthermore, a shielding ring is fixedly connected to the inner wall of the guide cover near the water inlet pipe. The side of the shielding ring fits into the corresponding side wall of the inner groove, and the inner circumferential side wall of the shielding ring is located at the edge of the corresponding water inlet.

[0013] Furthermore, the flow control assembly includes a control rod, which is fixedly connected to the side of the corresponding guide cover. A sealing rod is sleeved on the control rod, and the end of the sealing rod extends into the corresponding water inlet. A sealing spring is also fixedly connected between the sealing rod and the corresponding guide cover.

[0014] Furthermore, the sealing rod is inclined at one end of the water inlet hole, and the inclined end of the sealing rod fits against the outer edge of the corresponding water inlet hole.

[0015] Furthermore, pulleys are rotatably connected to the outer periphery of both the inlet pipe and the outlet pipe, and the side of the pulley is fixedly connected to the corresponding side of the roller.

[0016] Furthermore, the drainage groove is located at the inner peripheral edge of the inner groove, a gap is left between the water inlet and the inner peripheral side of the inner groove, and the outer peripheral side of the guide cover is fixedly connected to the inner peripheral side of the inner groove.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] 1. The conveying roller for seamless pipe production can control the water flow rate and conveying efficiency according to the temperature of the roller itself. This allows the low-temperature water to quickly cool and exchange heat with the roller, preventing the water temperature from rising too quickly and affecting the temperature of the subsequent water conveyance, which in turn affects the cooling of the roller and increases the wear and tear on the roller due to temperature.

[0019] 2. The conveyor roller used for seamless tube production has a gap between the water inlet and the inner circumference of the inner groove to prevent the water flow from directly washing against the inner circumference of the inner groove due to centrifugal force. This would make it difficult for the water to pass through the water inlet quickly and enter the middle of the inner groove to exchange heat with the roller.

[0020] 3. The conveyor roller for seamless tube production has a drainage groove located on the inner circumference of the inner groove, and the drainage groove is flared near the middle of the inner groove. This allows the water to fill the inner groove and exchange heat with the roller body before being discharged from the drainage groove, thus preventing water from being discharged directly without heat exchange.

[0021] 4. The conveying roller used for seamless pipe production has a limiting rod fixedly connected to the side of the sealing plug away from the water inlet pipe. The limiting rod is used to limit the control spring to prevent the control spring from being affected by the rotation of the roller body, which would cause the control spring to shake, and in turn cause the sealing plug to shake. This would cause the side of the sealing plug to abut against the end of the water inlet pipe, making it difficult for the sealing plug to control the water flow, and affecting the subsequent cooling and flow control of the roller body.

[0022] 5. In the conveying roller of this seamless tube production, the tube column is used to reduce the volume of water in the inner tank, so that the water can be filled quickly and the water can contact the circumferential side of the inner tank, thereby performing rapid heat exchange inside the roller. At the same time, the water flows into the middle of the inner tank from the water inlet, and after exchanging heat with the inner wall of the inner tank, it is discharged from the drain trough, thereby achieving the cooling effect.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0036] See also Figures 1-8As shown, according to Embodiment 1 of the present invention, a conveying roller for seamless tube production is provided, comprising: a roller body 1, an inner groove 2 is provided inside the roller body 1, and through holes 3 are provided on both sides of the roller body 1. The two through holes 3 are connected to the inner groove 2, and an inlet pipe 4 and an outlet pipe 5 are respectively rotatably connected in the two through holes 3.

[0037] Guide covers 6 are fixedly connected to the two opposite side walls of the inner tank 2. A water inlet control mechanism 7 is installed inside the guide cover 6 located at the water outlet pipe 5 to control the water pressure of the inlet.

[0038] A flow diversion mechanism 8 is provided between the two guide covers 6, which is used to control the path of the water flow;

[0039] A flow control component 9 is also provided between the two guide covers 6 to control the flow rate of water;

[0040] Both the inlet pipe 4 and the outlet pipe 5 are rotatably connected to pulleys 20 on their outer periphery, and the side of the pulley 20 is fixedly connected to the corresponding side of the roller body 1.

[0041] In this embodiment, reference Figure 1 Pulleys 20 are fixedly connected to both sides of the roller body 1. There is a gap between the water inlet pipe 4 and the water outlet pipe 5 corresponding to the pulleys 20. The roller body 1 is driven by the pulleys 20. In addition, an external water pump is used to connect the water inlet pipe 4 and the external pipeline is connected to the water outlet pipe.

[0042] refer to Figure 3 Additionally, the guide cover 6 is used to reinforce the inner wall of the inner tank 2 and to transport the water flow using the guide tank. The through hole 3 is used to install the corresponding water inlet pipe 4 and water outlet pipe 5, and the water outlet pipe 5 and the water inlet pipe are in a rotating sealed state when they are in the corresponding through hole 3.

[0043] refer to Figure 3 When the roller 1 is driven, a water pump is used to pump water into the water inlet pipe 4, so that the water can pass through the position of the water inlet control mechanism 7. This mechanism can deliver water to the inner tank 2 only after the water pressure reaches a certain pressure, so as to avoid the water pressure being too low and the water flow being unable to overcome the centrifugal force of the roller 1 rotation, thereby reducing the flow rate and flow rate of the water.

[0044] refer to Figure 3 Then the water will pass through the diversion mechanism 8, which is used to guide the flow of water so that the water can fully fit with the peripheral wall of the inner groove 2 and fully fit with the inside of the roller body 1, and carry away the heat after the roller body 1 comes into contact with the heated tube blank, thus effectively cooling the roller body 1.

[0045] refer to Figure 3The water flow passes through the flow control component 9. In the initial state, the component blocks the water flow path, allowing the water to be delivered at a normal flow rate. Subsequently, as the temperature of the roller 1 increases, the flow control component 9 opens the water flow path, allowing the water to flow completely, thereby increasing the water flow rate and thus increasing the flow velocity, which can remove the heat from the roller 1 more quickly.

[0046] In a further preferred embodiment of the invention, such as Figure 3 and Figure 4 As shown, the water inlet control mechanism 7 includes a control spring 10, which is fixedly installed at the center of the corresponding guide cover 6. A sealing plug 11 is fixedly connected to the end of the control spring 10. The end of the sealing plug 11 extends into the water inlet pipe 4, and its outer circumference is in contact with the inner circumference of the water inlet pipe 4.

[0047] In this embodiment, reference Figure 3 and Figure 4 When the water pump injects water into the inlet pipe 4, it will flush the sealing plug 11. The sealing plug 11 is supported by the control spring 10. At this time, when the force of the water flushing is greater than the supporting force of the spring, the sealing plug 11 can be moved. This means that the water needs a certain impact force to enter the inner groove 2 of the roller body 1. This avoids the water pressure being too low, which would result in the water flow speed being too slow, causing the water flow to stay in the inner groove 2 for too long, resulting in excessive water vapor evaporation and excessive pressure inside the inner groove 2. This would damage other internal components due to high pressure, affecting subsequent use. At the same time, it ensures that the water flow can quickly exchange heat at the high temperature of the roller body 1 during use under normal flow rate, improving cooling efficiency.

[0048] In a further preferred embodiment of the invention, such as Figure 3 and Figure 4 As shown, the end of the sealing plug 11 away from the water inlet pipe 4 is fixedly connected to a limiting rod 12. The end of the limiting rod 12 passes through the center position of the corresponding guide cover 6 side and is slidably connected to the guide cover 6.

[0049] In this embodiment, reference Figure 3 and Figure 4 A limiting rod 12 is fixedly connected to the side of the sealing plug 11 away from the water inlet pipe 4. The limiting rod 12 is used to limit the control spring 10 to prevent the control spring 10 from being affected by the rotation of the roller body 1, which would cause the control spring 10 to shake, thereby causing the sealing plug to shake. This would cause the side of the sealing plug to abut against the end of the water inlet pipe 4, making it difficult for the sealing plug 11 to control the water flow and affecting the subsequent cooling and flow control of the roller body 1.

[0050] In a further preferred embodiment of the invention, such as Figure 3 and Figure 4As shown, the drainage mechanism 8 includes a pipe column 13, which is fixedly connected between two guide covers 6. A gap is left between the outer periphery of the pipe column 13 and the inner periphery of the inner groove 2. A number of water inlet holes 14 are opened on the side of the guide cover 6 near the water inlet pipe 4, and a drainage groove 15 is opened on the inner periphery edge of the guide cover 6 near the water outlet pipe 5.

[0051] In this embodiment, reference Figure 3 and Figure 4 In the diversion mechanism 8, the tube column 13 is used to reduce the volume of water in the inner tank 2, so that the water can be filled quickly and the water can contact the circumferential side of the inner tank 2, thereby performing rapid heat exchange on the inside of the roller body 1. At the same time, the water flows into the middle of the inner tank 2 from the water inlet hole 14, and after heat exchange on the inner wall of the inner tank 2, it is discharged from the drain trough 15, thereby achieving the cooling effect.

[0052] In a further preferred embodiment of the invention, such as Figure 4 As shown, a shielding ring 16 is fixedly connected to the inner wall of the guide cover 6 near the water inlet pipe 4. The side of the shielding ring 16 is in contact with the corresponding side wall of the inner groove 2, and the inner circumferential side wall of the shielding ring 16 is located at the edge of the corresponding water inlet.

[0053] In this embodiment, reference Figure 4 A shielding ring 16 is fixedly connected to the inner wall of the corresponding guide cover 6. The shielding ring 16 is used to shield the water flow and prevent the water flow from being pushed to the circumferential side of the inner tank 2 due to centrifugal force, which would make it difficult for the water flow to enter the inner tank 2 directly from the water inlet 14 for heat exchange.

[0054] The inner circumference of the additional shielding ring 16 is inclined towards the water inlet 14, so that the water flow can directly enter the water inlet 14 along the inclined direction of the shielding ring 16, reducing the energy consumption during water transport and improving the flow efficiency of the water.

[0055] In a further preferred embodiment of the invention, such as Figure 4 As shown, the flow control assembly 9 includes a control rod 17, which is fixedly connected to the side of the corresponding guide cover 6. A sealing rod 18 is sleeved on the control rod 17, and the end of the sealing rod 18 extends into the corresponding water inlet 14. A sealing spring 19 is also fixedly connected between the sealing rod 18 and the corresponding guide cover 6.

[0056] In this embodiment, reference Figure 4When the water flows through the inlet hole 14, it will flush the sealing rod 18. The sealing rod 18 will slide on the control rod 17. The sealing rod 18, which is sleeved on the control rod 17, has a reserved movable position inside to avoid blocking the inlet hole 14. In addition, the sealing spring 19 is a thermal spring. At the initial temperature, it is in its longest extended state, which blocks the inlet hole 14.

[0057] When the temperature of the roller 1 increases, (a corresponding heat-conducting rod is fixedly connected to the outer periphery of the sealing spring 19, and the heat-conducting rod can be made of copper or silver) the heat absorbed by the roller 1 is introduced to the sealing spring 19. The sealing spring 19 will be in a contracted state when the temperature increases, thereby reducing the resistance when the water flows. Then the water flow expands, allowing the water flow to quickly enter the inner tank 2 to cool down the roller 1, thereby improving the water flow rate and the water flow heat exchange efficiency.

[0058] In a further preferred embodiment of the invention, such as Figure 4 and Figure 5 As shown, the sealing rod 18 is inclined at one end of the water inlet hole 14, and the inclined end of the sealing rod 18 is in contact with the outer edge of the corresponding water inlet hole 14.

[0059] In this embodiment, reference Figure 4 and Figure 5 The end of the sealing rod 18 is set at an angle, so that when the sealing rod 18 is opened in the initial state, the space for water to flow out is small, thus limiting the flow efficiency and flow rate of water. After the temperature rises, when the sealing rod 18 is completely pulled out of the water inlet 14, the water flow is unobstructed. At this time, the water can quickly enter the inner groove 2, thereby quickly filling the inner groove 2 and being discharged from the position of the drain groove 15, which can quickly perform heat exchange and cooling of the roller body 1.

[0060] In a further preferred embodiment of the invention, such as Figures 4-8 As shown, the drainage groove 15 is located at the inner peripheral edge of the inner groove 2, a gap is left between the water inlet hole 14 and the inner peripheral side of the inner groove 2, and the outer peripheral side of the guide cover 6 is fixedly connected to the inner peripheral side of the inner groove 2.

[0061] In this embodiment, reference Figures 4-8 A gap is left between the water inlet hole 14 and the inner circumference of the inner groove 2 to prevent the water flow from directly scouring the inner circumference of the inner groove 2 due to centrifugal force, thus making it difficult for the water flow to pass through the water inlet groove quickly and enter the middle of the inner groove 2 to perform heat exchange on the roller body 1.

[0062] The drainage trough 15 is located on the inner circumference of the inner trough 2, and the drainage trough 15 is flared near the middle of the inner trough 2. This allows the water to fill the inner trough 2 and exchange heat with the roller 1 before being discharged from the drainage trough 15, thus preventing the water from being discharged directly without heat exchange.

[0063] The outer periphery of the guide cover 6 is directly fixedly connected to the inner periphery of the inner groove 2. At this time, the guide cover 6 can be used to further support the roller body 1, improve the stability of the roller body 1 during use, and avoid reducing its own strength due to the internal opening.

[0064] Working principle: When the water pump injects water into the inlet pipe 4, it will flush the sealing plug 11. The sealing plug 11 is supported by the control spring 10. At this time, when the force of water flushing is greater than the supporting force of the spring, the sealing plug 11 can be pushed to move, so that the water needs a certain impact force to enter the inner groove 2 of the roller body 1.

[0065] The tubular column 13 is used to reduce the water volume in the inner trough 2, allowing the water to be filled quickly and to contact the circumferential side of the inner trough 2, thereby enabling rapid heat exchange inside the roller body 1. Simultaneously, the water flows into the middle of the inner trough 2 from the water inlet hole 14, heats the inner wall of the inner trough 2, and then discharges from the drain trough 15. In addition, a shielding ring 16 is fixedly connected to the inner wall of the corresponding guide cover 6. The shielding ring 16 is used to shield the water flow, preventing the water flow from being pushed to the circumferential side of the inner trough 2 by centrifugal force, which would make it difficult for the water flow to directly enter the inner trough 2 from the water inlet hole 14 for heat exchange in a timely manner. Furthermore, the inner circumference of the shielding ring 16 is inclined towards the water inlet hole 14, allowing the water flow to directly enter the water inlet hole 14 along the inclined direction of the shielding ring 16, reducing energy consumption during water transport and improving the flow efficiency of the water flow.

[0066] When water flows through the inlet hole 14, it will flush the sealing rod 18. The sealing rod 18 will slide on the control rod 17. The sealing rod 18, which is sleeved on the control rod 17, has a reserved movable position inside to avoid blocking the inlet hole 14. The sealing spring 19 is a thermal spring. At the initial temperature, it is in its longest extended state, which blocks the inlet hole 14.

[0067] When the temperature of the roller 1 increases, (a corresponding heat-conducting rod is fixedly connected to the outer periphery of the sealing spring 19, and the heat-conducting rod can be made of copper or silver), the heat absorbed by the roller 1 is introduced to the sealing spring 19. The sealing spring 19 will be in a contracted state when the temperature increases, thereby reducing the resistance when the water flows. Then the water flow expands, allowing the water flow to quickly enter the inner tank 2 to cool down the roller 1, thereby improving the water flow rate and the water flow heat exchange efficiency.

[0068] Finally, the end of the sealing rod 18 is set at an angle so that when the sealing rod 18 is opened in the initial state, the space for water to flow out is small, thus limiting the flow efficiency and flow rate of water. After the temperature rises, when the sealing rod 18 is completely pulled out of the water inlet 14, the water flow is unobstructed. At this time, the water can quickly enter the inner groove 2, thereby quickly filling the inner groove 2 and being discharged from the position of the drain groove 15, which can quickly perform heat exchange and cooling work on the roller body 1.

[0069] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
