Description

Technical Field

[0001] This utility model relates to the field of metal rolling technology, and in particular to a detachable roll for a cold rolling mill. Background Technology

[0002] Cold rolling mills are generally divided into two types: LG type and LD type. They are process equipment that uses annular holes to cold roll rough tubes. The main structure of the LG type cold rolling mill includes: bed, rotary feeding mechanism, roll support frame, main motor, mandrel, transmission system, electrical system, etc. Chinese utility model patent, authorized announcement number "CN215143372U", discloses a detachable roll for a cold rolling mill. When the roll body needs to be installed, firstly, the mounting block on one side of the roll body is placed into the mounting cavity. The mounting block is then pushed into the mounting cavity, causing the telescopic mechanism to retract and providing thrust to the mounting block. The end of the roll body with the slot is aligned with the locking block on the rotating rod and engaged. The thrust provided by the telescopic mechanism improves the stability of the engagement between the locking block and the slot. Then, the roll body is fixed using a fixing mechanism. Afterwards, the drive mechanism drives the rotating rod to rotate, performing the steel pipe rolling operation. When the roll body needs to be disassembled, firstly, the drive mechanism is stopped and the fixing mechanism is released, allowing the roll body to move. Then, the roll body is pushed towards the mounting rod, causing the telescopic mechanism to retract and the locking block to disengage from the slot. Finally, the mounting block is disassembled from the mounting cavity, completing the disassembly.

[0003] In the above technical solution, since the telescopic cylinder needs to be installed on a rotating mounting rod, and the telescopic cylinder needs to be connected to the air source through an air pipe, the connection and arrangement of the air pipe becomes complicated when the cylinder is installed on a rotating shaft. In order to avoid the air pipe from getting tangled, twisted or damaged during rotation, special rotary joints or cable chains are required to achieve dynamic connection of the air pipe. These devices not only increase the cost, but their own reliability and service life will also affect the stability of the entire system. Therefore, we propose a detachable roll for a cold rolling mill. Utility Model Content

[0026] Please see Figure 1-5 This utility model provides a technical solution: a detachable roll for a cold rolling mill, comprising:

[0027] Two roll support plates 1, two square mounting shafts 10 and a roll body 2, the two square mounting shafts 10 are fixedly connected to both sides of the roll body 2 respectively, and the roll body 2 is installed in the opposite surface of the two roll support plates 1;

[0028] A roll disassembly structure is located on the roll support plate 1.

[0029] The roll disassembly structure also includes two rotating shafts 3, a drive motor 6, a gear 7, and a rotating rod 15. Rotating grooves 14 are formed on the opposing surfaces of the two roll support plates 1. A second through groove 16 is formed inside each of the two rotating grooves 14. The two rotating shafts 3 are rotatably connected to the interior of their respective rotating grooves 14. Mounting grooves 4 are formed on the opposing surfaces of the two rotating shafts 3. Two square mounting shafts 10 are slidably connected to their respective mounting grooves 4. A first through groove 13 is formed inside each of the two mounting grooves 4. Both first through grooves 13 communicate with the interior of their respective second through grooves 16. The drive motor 6 is fixedly mounted on the corresponding roll support plate 1. The output end of the drive motor 6 is fixedly connected to the rotating rod 15. The end of the rotating rod 15 away from the drive motor 6 rotates through the corresponding roll support plate 1 and is fixedly connected to the gear 7. A gear ring 8 is fixedly sleeved on the rotating shaft 3 near the gear 7, and the gear 7 meshes with the gear ring 8.

[0030] The roll disassembly structure also includes two electric push rods 5, two square insert rods 11, and two rotating rings 12. The two electric push rods 5 are fixedly installed on the corresponding roll support plate 1. The two square insert rods 11 are slidably connected in the corresponding first through groove 13. The two rotating rings 12 are fixedly connected to the corresponding square insert rods 11. The telescopic ends of the two electric push rods 5 pass through the corresponding second through groove 16 and are rotatably connected to the inside of the corresponding rotating ring 12.

[0031] Both square mounting shafts 10 have square slots 9 on their opposite sides. Both square rods 11 are inserted into the corresponding square slots 9. Both square slots 9 are connected to the interior of the corresponding first through slots 13.

[0032] Furthermore, when driving the roll body 2, the drive motor 6 is started by connecting an external power source. The drive motor 6 drives the rotating rod 15 to rotate, and the rotation of the rotating rod 15 drives the corresponding gear 7 to rotate. The rotation of the gear 7 drives the corresponding rotating shaft 3 to rotate through the gear ring 8. Since the telescopic ends of the two electric push rods 5 can limit the two square mounting shafts 10, it is convenient for the rotating shaft 3 near the drive motor 6 to drive the roll body 2 to rotate. When disassembling the roll body 2, the two electric push rods 5 are started by connecting an external power source. The two electric push rods 5 will drive the corresponding square insert rod 11 to slide inside the first through groove 13 and the second through groove 16 through the corresponding rotating ring 12. This facilitates the square insert rod 11 to slide out from the inside of the corresponding mounting slide groove 4, so that the square insert rod 11 can be disengaged from the inside of the corresponding square slot 9. This makes it easier to remove the roll body 2 and the two square mounting shafts 10 from the two mounting slide grooves 4, thus facilitating the disassembly of the roll body 2.

[0033] With the cooperation of electric push rod 5, rotating ring 12, square insert rod 11 and rotating shaft 3, the two square mounting shafts 10 can be slidably connected in the corresponding mounting grooves 4 to install the roll body 2. With the two square insert rods 11 inserted into the corresponding square slots 9, it is convenient for the two square insert rods 11 to limit and fix the installed roll body 2. At the same time, the two electric push rods 5 do not need to rotate synchronously with the roll body 2, which further improves the stability of the disassembly structure on the roll body 2.
