Description

Technical Field

[0001] This utility model relates to metal tube processing equipment, and more particularly to an online annealing and cooling device for copper and aluminum tubes. Background Technology

[0002] Currently, online annealing production lines for copper and aluminum tubes both domestically and internationally typically require heating and then rapidly cooling the copper and aluminum tubes. Traditional cooling devices require placing carbon guide sleeves on the workpieces during the cooling process to center them and prevent them from wobbling and causing scratches after annealing. However, carbon guide sleeves are prone to wear during use, requiring frequent replacements. This not only affects the production line's operating costs but also increases its competitiveness in industrial sectors that emphasize cost reduction and efficiency improvement, hindering large-scale promotion and industrialized production. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an online annealing and cooling device for copper and aluminum tubes, which has the advantage of low maintenance cost.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an online annealing cooling device for copper and aluminum tubes, comprising: a water inlet shell, a jet ring, and a flow regulating ring. The water inlet shell is a tee pipe with openings at both ends and the bottom. The bottom end of the water inlet shell is connected to a water pipe. The jet ring includes a tube body with openings at both ends, a sealing protrusion located at the rear end of the tube body and protruding radially outward along the tube body, and an inclined notch opened through the outer wall of the front end of the tube body. The jet ring can extend into the water inlet shell, and the sealing protrusion can fit tightly against the inner wall of the rear end of the water inlet shell. The outer wall of the tube body and the inner wall of the water inlet shell... There is a gap between the walls, and the two ends of the flow regulating ring are open. The rear end of the flow regulating ring protrudes outward along the axial direction of the flow regulating ring to form an adjusting protrusion. The rear end of the flow regulating ring can extend into the water inlet shell. The adjusting protrusion can extend into the gap between the outer wall of the pipe body and the inner wall of the water inlet shell and fit tightly against the outer wall of the pipe body and the inner wall of the water inlet shell. The inner diameter of the pipe body and the inner diameter of the flow regulating ring are both smaller than the outer diameter of the workpiece. The workpiece can extend into the pipe body and the flow regulating ring. The water in the pipe can flow into the gap through the opening at the bottom of the water inlet shell. The water in the gap can be sprayed into the space between the workpiece and the pipe body through the notch.

[0005] Optionally, the sealing protrusion has a positioning port, and the rear end of the water inlet shell is threaded with a first set screw. The end of the first set screw can extend into the positioning port. The adjusting protrusion can slide and fit tightly against the outer wall of the pipe and the inner wall of the water inlet shell. The front end of the water inlet shell is threaded with a second set screw. The second set screw can fix or loosen the flow regulating ring. The inner peripheral wall of the adjusting protrusion can partially cover the opening end of the notch on the outer peripheral wall of the pipe on one side.

[0006] Optionally, the number of notches is greater than one, the notches are evenly distributed around the axis of the pipe body, the inner diameter of the pipe body is the same as the inner diameter of the flow regulating ring, and the inner diameter of the regulating protrusion is greater than the inner diameter of the flow regulating ring.

[0007] Optionally, the jet ring and the flow regulating ring are coaxial.

[0008] Optionally, the outer wall of the adjustment protrusion is flush with the outer wall of the flow regulating ring.

[0009] Alternatively, the number of gaps may be twelve.

[0010] The beneficial technical effects of this utility model are as follows: The online annealing cooling device for copper and aluminum tubes includes a water inlet shell, a spray ring, and a flow regulating ring. In use, the device is first placed in the workpiece's movement path. The workpiece requiring cooling can extend into the tube and flow regulating ring during movement. Then, water is injected into the opening at the bottom of the water inlet shell. The water flows into the gap through this opening. Because the two ends of the gap are blocked by sealing and adjusting protrusions, the water in the gap can only be ejected through the notch. The water ejected from the notch forms a water wall that isolates the workpiece from the inner wall of the tube. Simultaneously, the water wall restricts workpiece movement, providing centering and preventing scratches during movement. The water wall also prevents direct contact between the workpiece and the tube or flow regulating ring. Compared to using a direct-contact carbon guide sleeve, using a water wall to center the workpiece eliminates the need for periodic replacement of the carbon guide sleeve, resulting in lower maintenance costs. It has the advantage of low maintenance costs. Attached Figure Description

[0016] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0017] This specific embodiment details the online annealing and cooling device for copper-aluminum tubes described in this application, such as... Figures 1-3 As shown, the online annealing cooling device for copper and aluminum tubes includes: a water inlet shell 1, a jet ring 2, and a flow regulating ring 3. The water inlet shell 1 is a tee pipe with openings at both ends and the bottom. The bottom end of the water inlet shell 1 is connected to a water pipe. The jet ring 2 includes a tube body 21 with openings at both ends, a sealing protrusion 22 located at the rear end of the tube body 21 and protruding radially outward along the tube body 21, and a notch 23 obliquely penetrating the outer wall of the front end of the tube body 21. The jet ring 2 can extend into the water inlet shell 1, and the sealing protrusion 22 can fit tightly against the inner wall of the rear end of the water inlet shell 1. There is a gap 6 between the outer wall of the tube body 21 and the inner wall of the water inlet shell 1. The two ends of the flow regulating ring 3 are open. The rear end of the flow regulating ring 3 protrudes outward along the axial direction of the flow regulating ring 3 to form an adjusting protrusion 31. The rear end of the flow regulating ring 3 can extend into the water inlet shell 1. The adjusting protrusion 31 can extend into the gap 6 between the outer wall of the pipe body 21 and the inner wall of the water inlet shell 1 and fit tightly against the outer wall of the pipe body 21 and the inner wall of the water inlet shell 1. The inner diameter of the pipe body 21 and the inner diameter of the flow regulating ring 3 are both smaller than the outer diameter of the workpiece. The workpiece can extend into the pipe body 21 and the flow regulating ring 3. The water in the water pipe can flow into the gap 6 through the opening at the bottom of the water inlet shell 1. The water in the gap 6 can be sprayed into the space between the workpiece and the pipe body 21 through the notch 23. In use, the online annealing cooling device for copper and aluminum tubes is first placed in the workpiece's movement path. The workpiece requiring cooling can extend into the tube body 21 and flow regulating ring 3 during movement. Then, water is injected into the opening at the bottom of the water inlet housing 1. The water flows into the gap 6 through the opening at the bottom of the water inlet housing 1. Because the two ends of the gap are blocked by sealing protrusions 22 and adjusting protrusions 31 respectively, the water in the gap 6 can only be ejected through the notch 23. The water ejected from the notch 23 forms a water wall that isolates the workpiece from the inner wall of the tube body 21. Simultaneously, the water wall restricts workpiece movement, providing centering and preventing scratches during movement. The water wall also prevents the workpiece from directly contacting the tube body 21 or flow regulating ring 3. Compared to using a direct-contact carbon guide sleeve, using a water wall to provide centering eliminates the need for periodic replacement of the carbon guide sleeve, resulting in lower maintenance costs. It has the advantage of low maintenance costs.

[0018] Optionally in this embodiment, a positioning port is provided on the sealing protrusion 22, and a first set screw 4 is threadedly connected to the rear end of the water inlet shell 1. The end of the first set screw 4 can extend into the positioning port. The adjusting protrusion 31 can slide and fit tightly against the outer wall of the pipe body 21 and the inner wall of the water inlet shell 1. A second set screw 5 is threadedly connected to the front end of the water inlet shell 1. The second set screw 5 can fix or loosen the flow regulating ring 3. The inner peripheral wall of the adjusting protrusion 31 can partially cover the opening end of the notch 23 corresponding to the outer peripheral wall of the pipe body 21. When it is necessary to adjust the water flow, first loosen the second set screw 5, and then slide the flow regulating ring 3 to adjust the range of the adjusting protrusion 31 covering the notch 23 to adjust the water flow. After adjustment, tighten the second set screw 5 again.

[0019] Optionally in this embodiment, the number of notches 23 is greater than one, the notches 23 are distributed at equal intervals around the axis of the pipe body 21, the inner diameter of the pipe body 21 is the same as the inner diameter of the flow regulating ring 3, and the inner diameter of the regulating protrusion 31 is greater than the inner diameter of the flow regulating ring 3.

[0020] Optionally in this embodiment, the jet ring 2 and the flow regulating ring 3 are coaxial.

[0021] Optionally in this embodiment, the outer wall of the adjustment protrusion 31 is flush with the outer wall of the flow regulating ring 3.

[0022] Optionally, in this embodiment, the number of notches 23 is twelve. The twelve notches 23 simultaneously eject water jets, which converge to form a ring-shaped water wall. When the workpiece sways and comes into contact with the water wall, the water flow forming the water wall impacts the workpiece, pushing it away from the water wall in the opposite direction. This limits the workpiece's swaying in the radial direction, achieving a centering function. When the workpiece is long, multiple online annealing cooling devices for copper-aluminum tubes can be connected in series along the workpiece's axis to ensure the effect.

[0023] The online annealing and cooling device for copper and aluminum tubes described in this embodiment has the advantage of low maintenance costs.
