Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, and in particular to a fan-shaped plate of a coiler with a split half-structure. Background Technology

[0002] A coiler is an auxiliary device in a steel rolling mill that coils hot-rolled or cold-rolled steel into a coil shape. On hot strip continuous rolling mills, cold strip continuous rolling mills, and wire rod mills, it is located after the finished product stand. On single-stand reversible cold strip rolling mills, it is installed before and after the mill. The sector plate is the core component of the coiler's coil in a hot-rolled strip steel production line. The sector plate of the coiler is mainly used to support and fix the strip during the coiling process. During operation, it is subjected to radial pressure, temperature stress, and dynamic loads, and is prone to wear, cracks, and deformation. After long-term use, it is easily worn and needs to be disassembled, maintained, or replaced regularly.

[0003] For example, patent number CN221311901U discloses a split-type cold rolling coiler sector plate, belonging to the technical field of coiler sector plates. A split-type cold rolling coiler sector plate includes a main sector plate, two transition plates, and several countersunk screws. The transition plates are symmetrically installed on both sides of the main sector plate using countersunk screws. Several first threaded holes are formed on the upper surfaces of both sides of the main sector plate. The transition plates have second threaded holes. The countersunk screws pass sequentially through the second threaded holes of the transition plates and the first threaded holes of the main sector plates and are threaded into the first threaded holes of the main sector plates, thereby fixing the transition plates to the main sector plate.

[0004] However, the existing coiler sector plate front end adopts an integral design, which has a large overall structure and heavy weight. The disassembly and assembly process requires large hoisting equipment, which limits the operating space. At the same time, the disassembly process is time-consuming, which increases the downtime of the production line. In addition, the heavy structure can easily cause safety accidents when operated manually. Utility Model Content

[0005] To overcome the problems of the integrated design of the front end of the coiler's sector plate, which results in a large overall structure with high weight, requires large hoisting equipment for disassembly and assembly, has limited operating space, is time-consuming to disassemble, leading to increased production line downtime, and is prone to safety accidents due to the bulky structure during manual operation.

[0006] The technical solution of this utility model is as follows: a split-type coiler fan-shaped plate, including a fan-shaped plate body, a split mounting block, a stepped groove one, a connecting sleeve, a stepped groove two, a threaded hole, a fixing cover, a mounting groove, and fixing bolts; a split mounting block is provided on the right side of the fan-shaped plate body, a stepped groove one is provided at the right end of the split mounting block, a connecting sleeve is provided on the right side of the split mounting block, a stepped groove two is provided on the left side of the connecting sleeve, a threaded hole is provided at the right end of the connecting sleeve, a fixing cover is provided on the right side of the connecting sleeve, a mounting groove is provided on the outer side of the fixing cover, and a fixing bolt is provided on the inner side of the mounting groove.

The fixing cover is installed on the right end of the connecting sleeve, and the fixing bolt is passed through the mounting hole in the mounting groove and threadedly connected to the threaded hole, so as to realize the rapid assembly of each structure. By setting the split mounting block, the weight of the split structure is reduced, and it can be operated by a single person without the need for large equipment, reducing the risk of hoisting. In case of partial damage, only one side half component needs to be replaced, reducing spare parts costs.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Coiling machines are used in many industries. A coiling machine is a mechanical device that rolls products into coils. In terms of complexity, the steel plate coiling machine in the metallurgical industry is representative. Coiling machines are driven by electricity, fluid, etc. A coiling machine generally consists of the core equipment, the coil (spool), auxiliary coiling equipment (auxiliary forming equipment), and forming rollers. During the product coiling process, the product is mainly formed on the spool, which is generally driven by a motor. The auxiliary coiling rollers are also typically driven by a motor to rotate, while hydraulic cylinders drive the rollers to move, facilitating smooth coiling.

[0024] Coilers are mainly used to wind long rolled products into coils or sheets. In modern cold-rolled strip steel workshops, coilers are also widely used in shearing, pickling, grinding and polishing heat treatment, tin plating and galvanizing units.

[0025] Tension coilers are used on reversible or irreversible cold-rolled sheet or strip rolling lines. These coilers not only coil (unwind) the rolled product, but also apply tension to it. This is to stabilize the rolling process, make the coil tighter, and ensure the correct orientation of the rolled product as it enters and exits the rolls.

[0026] During the rolling process, it is generally necessary to maintain front tension and back tension. By relying on these tensions, the pressure acting on the rolls during rolling can be reduced, and strip warping can be minimized, which is beneficial to improving the surface quality of the strip.

[0027] Due to the differences in processes between strip steel production and wire rod production, and between cold strip steel production and hot strip steel production, coilers also have their own characteristics and functions, which leads to differences in their structures;

[0028] The coiler sector plate is a core component of the coiler drum in a hot-rolled strip steel production line. It is primarily used to support and fix the strip during the coiling process, ensuring coiling accuracy and stability.36 Its structure is typically an arc-shaped plate (e.g., a 307.5mm radius design), achieving high load-bearing capacity and wear resistance through special materials and processes.

[0029] The curved plate is provided with mounting holes (such as 16 disc spring holes and bolt holes) for connection and fixation and stress dispersion. It adopts a non-uniform fit design with the wedge sleeve to reduce stress concentration and suppress crack generation.

[0030] Typically, multiple processes such as turning, milling, and boring are used in tandem to ensure flatness, hole diameter accuracy, and arc matching. Improvements in forging technology (such as "back-to-back" forging) increase the yield by 3%-5% and improve processing efficiency by more than 80%.

[0031] It is mainly compatible with hot rolling coilers of 1750mm and above to meet the requirements of high temperature and fast coiling. It can also be extended to cold rolling sheet production lines to improve transmission efficiency through high-precision couplings (such as cross shaft universal couplings).

[0032] Please see Figures 1-5This utility model provides an embodiment: a split-type coiler fan-shaped plate, including a fan-shaped plate body 1, and further including a split mounting block 2, a stepped groove 3, a connecting sleeve 4, a stepped groove 2 5, a threaded hole 6, a fixing cover 7, a mounting groove 8, and a fixing bolt 9; the split mounting block 2 is provided on the right side of the fan-shaped plate body 1, the right end of the split mounting block 2 has a stepped groove 3, the right side of the split mounting block 2 has a connecting sleeve 4, the left side of the connecting sleeve 4 has a stepped groove 2 5, the right end of the connecting sleeve 4 has a threaded hole 6, the right side of the connecting sleeve 4 has a fixing cover 7, the outer side of the fixing cover 7 has a mounting groove 8, and the inner side of the mounting groove 8 has a fixing bolt 9.

The front end of the original integral fan-shaped plate is divided into two symmetrical split mounting blocks 2, which are connected by high-strength bolts or pins. Positioning pins and grooves are provided on the mating surface of the split mounting blocks 2 to ensure installation accuracy. By setting the split mounting blocks 2, the weight of the split structure is reduced, and it can be operated by a single person without the need for large equipment, reducing the risk of hoisting. In case of partial damage, only one side of the half-part needs to be replaced, reducing spare parts costs.

[0034] Please see Figures 2-5 In this embodiment, the left end of the connecting sleeve 4 and the right end of the split mounting block 2 are adapted to each other, the first step groove 3 and the second step groove 5 are engaged with each other, the left end of the fixed cover 7 and the right end of the connecting sleeve 4 are adapted to each other, the mounting grooves 8 are arranged in a ring array about the fixed cover 7, the inner side of the mounting groove 8 is provided with a mounting hole 81, the fixing bolt 9 is arranged through the mounting hole 81, the left end of the fixing bolt 9 extends to the left side of the fixed cover 7 through the mounting hole 81, and the fixing bolt 9 is threadedly connected to the inner side of the threaded hole 6. The fan-shaped plate body 1 is installed on the outside of the pyramid axis, and the split mounting block 2 is installed on the right end of the fan-shaped plate body 1.

The fixed cover 7 is installed on the right end of the connecting sleeve 4, and the fixing bolt 9 passes through the mounting hole 81 in the mounting groove 8 and is threadedly connected to the threaded hole 6, so as to realize the rapid assembly of each structure.

[0035] During operation, the main body 1 of the sector plate is installed on the outside of the pyramid axis, and the split mounting block 2 is installed on the right end of the main body 1 of the sector plate. The left end of the connecting sleeve 4 and the right end of the split mounting block 2 are engaged with each other through the cooperation of the first step groove 3 and the second step groove 5. The fixing cover 7 is installed on the right end of the connecting sleeve 4, and the fixing bolt 9 is passed through the mounting hole 81 in the mounting groove 8 and threadedly connected to the threaded hole 6, so as to realize the rapid assembly of each structure and facilitate its subsequent disassembly and maintenance.

[0036] The above steps address the issues of the integrated design of the front end of the coiler's sector plate, which results in a large overall structure, heavy weight, reliance on large hoisting equipment during disassembly and assembly, limited operating space, long disassembly time, increased production line downtime, and the risk of safety accidents due to the bulky structure during manual operation.
