Description

Technical Field

[0001] This utility model relates to the field of roller pressing device technology, and in particular to a roller pressing device for continuous casting of large-diameter copper tubes. Background Technology

[0002] Copper pipe, also known as red copper pipe, is a type of non-ferrous metal pipe, produced through pressing and drawing into seamless tubes. Copper pipe possesses excellent electrical and thermal conductivity, making it a primary material for conductive and heat dissipation components in electronic products. It has also become the preferred choice for modern contractors installing water supply, heating, and cooling pipes in all residential and commercial buildings. Copper pipe exhibits strong corrosion resistance, is not easily oxidized, and does not readily react chemically with certain liquid substances, making it easy to bend and shape. In the continuous casting production process of copper pipe, a three-roll planetary rolling mill is used to roll it to achieve the appropriate production dimensions.

[0003] In existing rolling mills for continuous casting of large-diameter copper tubes, the roller head and roller bar are typically designed as a single unit. This design has significant limitations in practical use. When the roller head needs to be replaced due to wear or damage, the entire roller bar must be replaced simultaneously, resulting in material waste and increased maintenance costs. Furthermore, the single-unit structure hinders rapid equipment repair and replacement, impacting production efficiency. Therefore, a modular design where the roller head and roller bar can be separated is urgently needed to reduce maintenance costs, extend equipment lifespan, and improve the overall economic efficiency and convenience of production.

[0021] 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.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution:

[0023] A rolling device for continuous casting of large-diameter copper tubes includes a base 1, a cylinder 3 mounted on the upper side of the base 1, a fixing rod 2 fixedly installed between the base 1 and the cylinder 3, a circular sleeve 4 mounted on the front side of the cylinder 3, and multiple sets of rollers 5 mounted on the front side of the cylinder 3. Roller sleeves 6 are fitted onto the ends of the rollers 5, and slots 7 are formed at the ends of the rollers 5. Inserted rods 8 are fixedly installed on the inner wall of the roller sleeves 6, and are disposed inside the slots 7. An inner cavity 9 is formed inside the rollers 5. A telescopic rod 10 is fixedly installed on the rear end face of the inner cavity 9. A push rod 11 is fixedly installed on the end of the telescopic rod 10. A first groove 12 is opened on the upper end face of the push rod 11. A slide rod 13 is slidably connected inside the first groove 12. An arc rod 14 is provided on the front side of the push rod 11. One end of the arc rod 14 is fixedly connected to the slide rod 13. A second groove 16 is opened on the upper end face of the arc rod 14. A slider 15 is slidably connected inside the second groove 16. The slider 15 is fixedly connected to the inner wall of the inner cavity 9.

[0024] A guide groove 17 is provided on the upper side of the inner cavity 9, and the arc rod 14 is slidably connected to the guide groove 17. A fixing groove 18 is provided on the outer surface of the insertion rod 8 for the arc rod 14.

[0025] When the roller sleeve 6 needs to be installed, insert the insertion rod 8 on the roller sleeve 6 into the slot 7 on the roller rod 5, and then activate the telescopic rod 10 inside the inner cavity 9. The telescopic rod 10 will drive the push rod 11 to move. The upper end face of the push rod 11 has a sliding groove 12 on both sides, and the sliding rods 13 on the two sets of symmetrically arranged arc rods 14 are slidably connected to the corresponding sliding groove 12, thus pushing the arc rod 14 to move. The arc rod 14 has a sliding groove 16, and the fixed slider 15 is slidably connected to the sliding groove 16. Therefore, the slider 15 will guide the displacement direction of the arc rod 14. At the same time, the arc rod 14 is slidably connected to the guide groove 17. Thus, under the synchronous action of the guide groove 17 and the slider 15, the end of the arc rod 14 can be guided to insert into the fixed groove 18, and the insertion rod 8 is limited and fixed.

[0026] A push plate 19 is fixedly installed on the front end face of the push rod 11, and a top plate 20 is provided on the front side of the push plate 19. A spring 26 is fixedly installed between the top plate 20 and the inner wall of the inner cavity 9.

[0027] The insertion rod 8 has a groove 21, and the slot 7 has a protrusion 22 fixedly installed inside.

[0028] A limiting groove 23 is formed inside the protrusion 22, and a shape memory alloy 24 is slidably connected inside the limiting groove 23.

[0029] One end of the shape memory alloy 24 extends into the interior of the inner cavity 9 and is fixedly connected to the top plate 20.

[0030] The inner wall of the groove 21 is provided with a slot 25, and the other end of the shape memory alloy 24 is set in the slot 25.

[0031] Secondly, the push rod 11 moves, and simultaneously pushes the top plate 20 to move through the push plate 19. The top plate 20 will compress the spring 26 and squeeze the shape memory alloy 24, causing the shape memory alloy 24, which is slidably connected inside the limiting groove 23, to move. The other end of the shape memory alloy 24 extends out of the limiting groove 23 and inserts into the slot 25, further strengthening the fixing effect on the insert rod 8. When it is necessary to disassemble the roller sleeve 6, the reverse drive telescopic rod 10, in conjunction with the spring 26, can flip the above transmission structure, thereby contacting the fixing of the insert rod 8 and removing the roller sleeve 6 from the roller rod 5.

[0032] In existing rolling mills for continuous casting of large-diameter copper tubes, the roller head and roller rod 5 are usually designed as an integrated structure. This structure has significant limitations in practical use. When the roller head needs to be replaced due to wear or damage, the entire roller rod 5 must be replaced at the same time, resulting in material waste and increased maintenance costs. In addition, the integrated structure is not conducive to rapid repair and replacement of the equipment, affecting production efficiency. Therefore, there is an urgent need for a modular design where the roller head and roller rod 5 can be separated to reduce maintenance costs, extend the service life of the equipment, and improve the overall economy and convenience of production. Therefore, this utility model sets up a separate roller rod 5 and roller sleeve 6 structure, which allows the two to be detachably connected. This facilitates the individual disassembly and replacement of the roller sleeve 6 after prolonged use and wear, without the need to replace the entire roller rod 5. This greatly reduces maintenance costs and downtime. This design not only improves the maintainability and ease of use of the equipment, but also effectively extends the service life of the roller rod 5, improves production efficiency and economic benefits, and is suitable for continuous production scenarios such as continuous casting of large-diameter copper tubes.

[0033] Working principle: When roller sleeve 6 needs to be installed, insert rod 8 on roller sleeve 6 into slot 7 on roller 5. Then activate telescopic rod 10 inside inner cavity 9. Telescopic rod 10 will drive push rod 11 to move. Both sides of the upper end face of push rod 11 are provided with sliding groove 12. The sliding rod 13 on the two sets of symmetrically arranged arc rods 14 are slidably connected to the corresponding sliding groove 12, thus pushing the arc rod 14 to move. The arc rod 14 is provided with sliding groove 26, and the fixed slider 15 is slidably connected to sliding groove 26. Therefore, slider 15 will guide the displacement direction of arc rod 14. At the same time, arc rod 14 is slidably connected to guide groove 17. Thus, under the synchronous action of guide groove 17 and slider 15, the end of arc rod 14 can be guided to insert into fixed groove 18, limiting and fixing the insert rod 8.

[0034] Secondly, the push rod 11 moves, and simultaneously pushes the top plate 20 to move through the push plate 19. The top plate 20 will compress the spring 26 and squeeze the shape memory alloy 24, causing the shape memory alloy 24, which is slidably connected inside the limiting groove 23, to move. The other end of the shape memory alloy 24 extends out of the limiting groove 23 and inserts into the slot 25, further strengthening the fixing effect on the insert rod 8. When it is necessary to disassemble the roller sleeve 6, the reverse drive telescopic rod 10, in conjunction with the spring 26, can flip the above transmission structure, thereby contacting the fixing of the insert rod 8 and removing the roller sleeve 6 from the roller rod 5.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
