Description

Technical Field

[0001] This utility model belongs to the field of winding equipment technology, and more specifically, relates to a hot rolling winding machine drum and winding equipment. Background Technology

[0002] The function of the coil is to coil hot-rolled strip steel for transportation and storage. During the coiling process, the coil establishes a stable tension with the pinch rolls to ensure the quality of the coiled steel. The quality of the coiled steel directly affects the appearance and shape of the shipped steel coils. The coil expands and contracts under the action of a hydraulic cylinder, thereby achieving the purpose of coiling and uncoiling the steel.

[0003] Traditional hot-rolled coilers use a coupling to connect the piston rod and pull rod of a hydraulic cylinder. Under the action of the hydraulic cylinder, the pull rod stretches back and forth to complete the expansion and contraction of the coil. Fixing blocks (the size of the fixing blocks must be compatible) are installed before and after the coupling. These fixing blocks act as limiters, thereby achieving the specified stroke of the hydraulic cylinder and satisfying the desired size of the coil. For example, patent document CN112058945A discloses a pyramidal sleeve type coiler coiler, including a conductive slip ring installed at the tail of a geared motor. The right end of the geared motor is connected to a flange and fixed on the main shaft. The output shaft of the geared motor is connected to a lead screw via a coupling. The left and right ends of the lead screw are placed inside the main shaft via bearings, which are fixed by lock nuts. A transmission nut is provided on the lead screw, and four protruding positioning blocks are provided on the transmission nut. The four positioning blocks are located in the inner grooves of the main shaft at four positions. The four positioning blocks are connected and fastened to the pyramidal sleeve by screws. The pyramidal sleeve makes contact with the sector plate and the jaw sector plate via inclined surfaces.

[0004] Because traditional hot rolling coiler drum hydraulic cylinders have a large stroke margin, the fixing blocks are relatively thick and heavy. Moreover, the space is limited during disassembly and installation, and the excessive thickness and weight are not conducive to safe production. Summary of the Invention

[0005] The problem to be solved To address the problems existing in the prior art, this utility model provides a hot rolling coiler drum and coiling equipment, which removes the fixing blocks before and after the coupling, reducing the amount of processing, disassembly and installation work; the drum structure is redesigned so that the drum structure itself can play a limiting role to meet the purpose of large and small circles.

[0006] This utility model also provides a winding device having the above-mentioned hot-rolled winding machine drum.

[0007] Technical solution To solve the above problems, the present invention adopts the following technical solution.

[0008] This utility model provides a hot rolling coiler drum, comprising: The main shaft has four hook grooves of the same size evenly distributed along its circumference. Each hook groove has a groove of the same size, and a planar wedge is movably installed in the groove. A pull rod located inside the main shaft has a locking nut threadedly connected to the side of the pull rod away from the rotating hydraulic cylinder. Limiting sleeves are spaced apart on the circumferential surface of the pull rod, and an arc-shaped wedge is provided between two adjacent limiting sleeves. A hook-shaped wedge is provided at the top of the arc-shaped wedge, and a T-shaped block is formed at the top of the arc-shaped wedge. A T-shaped groove is provided at the bottom of the hook-shaped wedge, and the T-shaped groove of the hook-shaped wedge is connected to the T-shaped block at the top of the arc-shaped wedge. The top of the hook-shaped wedge forms a T-shaped platform. And a sector-shaped plate located on the outer side, the number of which is four spliced ​​together to form a circle, the bottom of the sector-shaped plate has two spaced hook bodies, wherein a receiving cavity is formed between the two hook bodies, the receiving cavity can fit the T-shaped platform; the two hook bodies are connected to the hook groove.

[0009] In one possible embodiment of this utility model, an extension shaft is provided near the locking nut on the main shaft.

[0010] In one possible embodiment of the present invention, a protective cover is also included; the two end faces of the protective cover are respectively engaged with the fan-shaped plate and the extension shaft.

[0011] In one possible embodiment of this utility model, the limiting spacer sleeve is engaged with the pull rod via a flat key.

[0012] In one possible embodiment of this utility model, the extension shaft and the pull rod are provided with oil inlet holes along the central axis. The oil inlet holes are connected to the arc-shaped wedges and are used to inject lubricating oil into the mating surfaces between the planar wedges, the hook wedges, and the fan-shaped plates.

[0013] In one possible embodiment of this utility model, the limiting spacer is fixedly connected to the arc-shaped wedge near the extension shaft by screws.

[0014] In one possible embodiment of this utility model, the planar wedge is provided with a blind hole, and a spring is installed in the blind hole. The spring is made of WV series high-temperature resistant spring steel, with a temperature resistance of up to 500℃. A cover plate is provided at the upper end of the spring. When the planar wedge is pushed up by the main shaft, the spring force first lifts the cover plate, buffering the force of the planar wedge acting on the sector plate, making the coiling of the steel more stable. The cover plate at the upper end of the spring is normally fixed in the planar wedge with screws; when in use, it needs to be installed in the drum, at which time the screws are removed. Due to the combined constraint of the sector plate and the main shaft, the cover plate and the spring are confined within the blind hole of the planar wedge.

[0015] This utility model also provides a winding device having the above-mentioned hot-rolled winding machine drum.

[0016] Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The hot rolling coiler of this utility model has a continuous hook groove processed on the left and right sides of each of the four sides of the main shaft, so that it can cooperate with the fan-shaped plate. When the coil expands to the large circle, the hook body of the fan-shaped plate presses against the hook groove of the main shaft, and the hook groove of the main shaft plays a limiting role. The middle of each side of the hook groove of the main shaft is processed into a T-shaped platform. When the fan-shaped plate falls down and the coil reaches the small circle, the inner plane of the fan-shaped plate falls on the T-shaped platform of the main shaft, and the T-shaped platform of the main shaft plays a limiting role. (2) The hot rolling coiler of this utility model achieves the purpose of limiting by processing the main shaft to form left and right hook grooves and T-shaped platform, thereby making the coil structure simpler and easier to install; (3) The hot rolling coiler of this utility model reduces the number of parts and reduces the manufacturing cost caused by the processing, disassembly and adaptation of the fixing block. Because the fixing block is too thick, it avoids the safety hazards caused by disassembling and installing the fixing block. Attached Figure Description

[0022] Example 1 like Figures 1 to 7 As shown, the hot rolling coiler drum of this embodiment includes a main shaft 1, a tie rod 3, a sector plate 4 and a protective cover 9. An extension shaft 10 is provided on the main shaft 1 near the locking nut 5. The two end faces of the protective cover 9 are respectively engaged with the sector plate 4 and the extension shaft 10.

[0023] The main shaft 1 is a hollow structure, and four hook grooves 1-1 of the same size are evenly opened along the circumference. The hook grooves 1-1 are filled with grooves 1-2 of the same size, and a planar wedge 2 is movably installed in the grooves 1-2.

[0024] exist Figure 1 , Figure 5 , Figure 6 and Figure 7In this configuration, the pull rod 3 is located inside the main shaft 1. A locking nut 5 is threaded onto the pull rod 3 on the side away from the rotating hydraulic cylinder. Limiting spacers 6 are spaced apart on the circumferential surface of the pull rod 3. The limiting spacers 6 are engaged with the pull rod 3 via a flat key. An arc-shaped wedge 7 is provided between two adjacent limiting spacers 6. A hook wedge 8 is provided at the top of the arc-shaped wedge 7. A T-shaped block 7-1 is formed at the top of the arc-shaped wedge 7. A T-shaped groove 8-1 is provided at the bottom of the hook wedge 8. The T-shaped groove 8-1 of the hook wedge 8 is engaged with the T-shaped block 7-1 at the top of the arc-shaped wedge 7. A T-shaped platform 8-2 is formed at the top of the hook wedge 8.

[0025] Combination Figure 2 and Figure 3 As shown, the outer sector plate 4 directly contacts the strip steel and is made of heat-resistant and wear-resistant stainless steel. The number of sector plates 4 is four, spliced ​​together to form a circle. The bottom of the sector plate 4 forms two spaced hook bodies 4-1, and a receiving cavity 4-2 is formed between the two hook bodies 4-1. The receiving cavity 4-2 can fit into the T-shaped platform 8-2. The two hook bodies 4-1 are connected to the hook groove 1-1.

[0026] exist Figure 1 In this configuration, the extension shaft 10 and the pull rod 3 are provided with an oil inlet 3-1 along their central axis. The oil inlet 3-1 is connected to the arc-shaped wedge 7 and provides lubricating oil to the mating surfaces between the planar wedge 2, the hook wedge 8, and the fan-shaped plate 4. Furthermore, the limiting sleeve 6 is fixedly connected to the arc-shaped wedge 7 near the extension shaft 10 by screws, ensuring that the limiting sleeve 6 can move together with the pull rod, while the screws also serve as circumferential positioning.

[0027] The cover plate 2-3 provided on the upper end of the spring 2-2 is normally fixed in the plane wedge 2 with screws; when in use, it needs to be installed in the drum, at which time the screws are removed; due to the joint restriction of the sector plate 4 and the main shaft 1, the cover plate 2-3 and the spring 2-2 are confined in the blind hole 2-1 of the plane wedge 2.

[0028] like Figure 2 As shown, a continuous hook groove is machined on each of the four sides of the main spindle along its axial direction to mate with the sector plate.
