Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, and more specifically, to a self-circulating cooling device for hot piercing of seamless steel pipes. Background Technology

[0002] Seamless steel pipes are rolled steel pipes without weld seams. Their specifications are expressed by the product of the outer diameter and the wall thickness. The production processes include hot rolling and cold drawing. The materials are available in various materials and shapes. In terms of performance, they are characterized by high strength, high toughness, high wear resistance, and high dimensional accuracy. They are widely used in energy, machinery manufacturing, construction, power and other fields.

[0003] In the production of seamless steel pipes, hot piercing is a common and crucial method. Hot piercing involves heating a solid steel billet and then rotating and advancing a mandrel to form a hollow tube. During this process, intense friction between the billet and the mandrel, along with heat transfer at high temperatures, generates a significant amount of heat. If the mandrel is not cooled effectively and promptly, it will easily deform and wear, severely impacting its service life and performance, thus negatively affecting the production quality and efficiency of the seamless steel pipe. Currently, in the hot piercing process for seamless steel pipes, external spraying is commonly used to cool the mandrel. While this method can reduce temperature to some extent, it consumes a large amount of water, resulting in extremely low water recycling rates. A large amount of high-quality water is wasted and not fully utilized, which is detrimental to the sustainable development of the entire industrial production. Furthermore, the direct discharge of the cooling medium (water) after use not only wastes resources but may also pollute the environment. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a self-circulating cooling device for hot piercing of seamless steel pipes, which has the advantage of automatically circulating and spraying cooling to the top rod.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-circulating cooling device for hot piercing of seamless steel pipes, comprising:

[0006] A fixing plate, wherein a water tank is fixedly installed at the bottom end of the fixing plate;

[0007] A cooling mechanism is provided at the bottom of the water tank.

[0008] The cooling mechanism includes a liquid pump, a double-ended pipe is fixedly sleeved inside the top of the liquid pump, an infusion pipe is fixedly sleeved at the top of the outer surface of the double-ended pipe, a locking block is movably engaged on the outer surface of the infusion pipe, and the locking block is fixedly connected to the outer surface of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The self-circulating cooling equipment of this patent constructs a complete water circulation system. After completing the cooling task of the top rod, the cooling water is not directly discharged as in the traditional way, but is returned to the water tank for recycling. This design greatly improves the utilization rate of water resources, greatly reduces the dependence on external water supply systems, effectively alleviates the water supply pressure in water-scarce areas, and reduces the discharge of a large amount of sewage containing impurities and high temperature because the cooling water is recycled.

When the screw rotates, it drives the toothed plate downward through the movable block. At this time, the toothed plate drives the rotating shaft to rotate in the opposite direction through the gear. At this time, the two support blocks will contact the push rod during rotation, thereby supporting the push rod, making the push rod more stable during hot piercing. Since the round block, rotating block and support block can all rotate, they will not hinder the movement of the push rod. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a self-circulating cooling device for hot piercing of seamless steel pipes, comprising:

[0025] Fixed plate 1, with a water tank 12 fixedly installed at the bottom end of fixed plate 1;

[0026] A cooling mechanism is located at the bottom of the water tank 12.

[0027] The cooling mechanism includes a liquid pump 13, a double-ended pipe 14 is fixedly sleeved inside the top of the liquid pump 13, a liquid delivery pipe 15 is fixedly sleeved at the top of the outer surface of the double-ended pipe 14, and a locking block 16 is movably locked on the outer surface of the liquid delivery pipe 15. The locking block 16 is fixedly connected to the outer surface of the fixing plate 1.

[0028] When the operator starts the liquid pump 13, the liquid pump 13 will drive the water in the water tank 12 to flow into the double-pass pipe 14. Then the water in the double-pass pipe 14 will be sprayed onto the outer surface of the top rod 8 through the infusion pipe 15, thereby cooling the top rod 8. During this process, the water will continue to slide down and eventually flow back into the water tank 12, thereby achieving the effect of automatically circulating and cooling the top rod 8. Due to the design of the locking block 16, it will have the effect of fixing the infusion pipe 15.

[0029] Among them, a fixed shaft 2 is fixedly sleeved inside the fixed plate 1, a rotating plate 3 is movably sleeved on the outer surface of the fixed shaft 2, a rotating block 5 is movably connected inside the rotating plate 3, the interior of the rotating block 5 is movably sleeved with the outer surface of the fixed shaft 2, a top rod 8 is movably connected to the outer surface of the rotating block 5, a round shaft 6 is fixedly sleeved inside the rotating plate 3, and a round block 7 is movably sleeved on the outer surface of the round shaft 6.

[0030] Since both the rotating plate 3 and the rotating block 5 are movably connected to the fixed shaft 2, they can rotate around the fixed shaft 2. When the rotating plate 3 rotates, it will drive the circular block 7 to rotate through the circular shaft 6. At this time, the circular block 7 will squeeze the push rod 8 during rotation, causing the push rod 8 to move. Subsequently, the push rod 8 will contact the rotating block 5 during movement. At this time, the circular block 7 and the rotating block 5 will cooperate to provide good support for the push rod 8. Since the circular block 7 is movably connected to the circular shaft 6, it can rotate around the circular shaft 6. Since both the rotating block 5 and the circular block 7 can rotate, they will not hinder the rotation and advancement of the push rod 8.

[0031] Among them, a hinge block 9 is fixedly installed on the outer surface of the fixed plate 1, a cylinder 10 is hinged on the hinge block 9, a connecting block 11 is movably sleeved inside the top of the cylinder 10, and the outer surface of the connecting block 11 is fixedly connected to the outer surface of the rotating plate 3.

[0032] When the cylinder 10 is running, the output end of the cylinder 10 will pull the connecting block 11. At this time, the connecting block 11 will drive the rotating plate 3 to rotate around the fixed shaft 2. At the same time, the cylinder 10 as a whole will rotate around the hinge point with the hinge block 9.

[0033] The bottom of the water tank 12 is fixedly installed with a protective shell 17. The motor 18 is fixedly installed inside the protective shell 17. The other end of the output shaft of the motor 18 is fixedly sleeved with a screw 19. The outer surface of the screw 19 is threaded with a movable block 20. The outer surface of the movable block 20 is fixedly installed with a toothed plate 21.

[0034] Due to the design of the protective shell 17, the motor 18 will be well protected. When the motor 18 is running, the screw 19 will rotate. Since the screw 19 is connected to the internal thread of the movable block 20, the screw 19 will drive the two toothed plates 21 to move up and down through the movable block 20.

[0035] Among them, the outer surface of the toothed plate 21 is meshed with a gear 22, and the gear 22 is fixedly sleeved with a rotating shaft 23. The outer surface of the rotating shaft 23 is movably sleeved with the inner surface of the outer surface of the fixed plate 1.

[0036] Since the toothed plate 21 is meshed with the gear 22, when the two toothed plates 21 move downward, they will drive the two rotating shafts 23 to rotate in the opposite direction through the two gears 22.

[0037] Both ends of the rotating shaft 23 are fixedly sleeved with movable rods 24, and the other end of the movable rod 24 is fixedly sleeved with a movable shaft 25. The outer surface of the movable shaft 25 is movably sleeved with a support block 4.

[0038] When the two rotating shafts 23 rotate in opposite directions, they will drive the two movable shafts 25 to rotate in opposite directions through the two sets of movable rods 24. Then, the two movable shafts 25 will drive the two support blocks 4 to rotate in opposite directions. Subsequently, the two support blocks 4 will come into contact with the push rod 8 during the reverse rotation. At this time, the two support blocks 4 will play a good supporting role for the push rod 8. Since the inside of the support block 4 is movably connected to the outer surface of the movable shaft 25, the support block 4 can rotate around the movable shaft 25 as the axis, so that the support block 4 will not hinder the rotation and advancement of the push rod 8.

[0039] Working principle and usage process of this utility model:

[0040] First, the operator places the push rod 8 inside the fixed plate 1. Then, the operator starts the motor 18, causing the screw 19 to rotate. Since the outer surface of the screw 19 is threaded into the inner part of the movable block 20, its rotation will drive the movable block 20 downwards. Simultaneously, the two toothed plates 21 will move downwards under the influence of the movable block 20. Because the outer surfaces of the toothed plates 21 mesh with the outer surfaces of the gears 22, their downward movement will cause the two gears 22 to rotate in the opposite direction. At this point, the two rotating shafts 23 will rotate in conjunction with the fixed plate 1 under the influence of the two gears 22. The sleeve joint rotates in the opposite direction as the axis. At the same time, the two rotating shafts 23 will drive the two movable shafts 25 to rotate in the opposite direction through the two sets of movable rods 24. At this time, the two support blocks 4 will rotate in the opposite direction under the drive of the two movable shafts 25. Then, the outer surface of the two support blocks 4 will contact the outer surface of the push rod 8 in the opposite direction. At this time, the two support blocks 4 will provide good support for the push rod 8. And because the inside of the support block 4 is movably sleeved with the outer surface of the movable shaft 25, the support block 4 can rotate around the movable shaft 25 as the axis, so that the support block 4 will not hinder the rotation and advancement of the push rod 8.

[0041] Next, the operator starts cylinder 10. At this time, the output end of cylinder 10 will pull the connecting block 11, causing the connecting block 11 to drive the rotating plate 3 to rotate around the fixed shaft 2. Then, the rotating plate 3 will drive the round block 7 to rotate through the round shaft 6. Subsequently, the outer surface of the round block 7 will contact the outer surface of the push rod 8 during rotation and squeeze and push the push rod 8. When the push rod 8 contacts the rotating block 5 under the drive of the round block 7, the round block 7 and the rotating block 5 will cooperate to provide good support for the push rod 8. Since the inside of the round block 7 and the rotating block 5 are movably connected to the outer surfaces of the round shaft 6 and the fixed shaft 2 respectively, the round block 7 and the rotating block 5 can rotate around the round shaft 6 and the fixed shaft 2 respectively. Thus, the round block 7 and the rotating block 5 will not obstruct the rotation and advancement of the push rod 8. Due to the design of the support block 4, the round block 7 and the rotating block 5, the push rod 8 is stably supported.

[0042] During the hot piercing process of the push rod 8, a large amount of heat will be generated. At this time, the operator starts the liquid pump 13. The liquid pump 13 will draw water from the water tank 12 and deliver it to the inside of the double-pass pipe 14. Then, this water will flow through the inside of the double-pass pipe 14 to the inside of the infusion pipe 15. Then, this water will be sprayed onto the outer surface of the push rod 8 through the inside of the infusion pipe 15, thereby achieving the effect of automatically cooling the push rod 8. When the water is sprayed onto the outer surface of the push rod 8, it will continue to slide down under the influence of gravity. Then, the water tank 12 will collect this sliding water, so that the water flows back into the inside of the water tank 12 to achieve a circulation effect, thereby realizing the function of automatically circulating spraying and cooling the push rod 8.
