Description

Technical Field

[0001] This utility model relates to the field of edge rolling machine technology, and in particular to a fixed turntable support for an edge rolling machine that prevents jamming. Background Technology

[0002] The recoiling process in cold rolling mills requires processing and rewinding of the leveled steel coils according to production process requirements using a recoiling unit. This includes three main processes: straightening, edge trimming, and oiling. These processes further improve the strip shape, ensure strip width accuracy, enhance the strip surface's rust resistance, and ensure that the finished steel coils meet product quality and customer requirements.

[0003] The edge-coiling machine is a crucial piece of equipment in the recoiling unit. In the cold rolling mill's recoiling process, a disc shear is used to trim the strip steel. After trimming, the strip steel yields ultra-narrow strip steel with a width of around 5mm; this ultra-narrow strip steel is called edge wire. Edge wire typically has no processing value, but it is considered clean scrap steel and is ideally suited as raw material for steelmaking. The edge wire generated from strip trimming is quite fragmented, requiring the edge-coiling machine to coil it into a coil-like shape similar to wire rod for transportation and furnace charging.

[0004] like Figure 1 As shown, existing rewinding and edge-pressing machines generally include a frame, base, motor, reducer, mandrel, and fixed turntable support. The fixed turntable support, drive motor, and reducer are all mounted on the frame. The drive motor is connected to the reducer, and the reducer is connected to one end of the mandrel to drive it. The other end of the mandrel is connected to the fixed turntable support. The fixed turntable support is installed on one side of the frame, as shown in the image. Figure 1 As shown at point A in the diagram. The fixed turntable support is used to support the spindle and fix the turntable, reducing the vibration generated by the spindle during operation and making the spindle rotate more smoothly.

[0005] like Figure 2 As shown, the existing fixed turntable support used in rewinding and edge-coating machines consists of two parts: the support base and the shaft head. The gap between the support base and the shaft head flange is relatively large, allowing edge wire to easily enter the bearing rolling elements within the support base, causing bearing failure and jamming of the support base, rendering the entire edge-coating machine inoperable. When the fixed turntable support base jams, a complete shutdown is required for repairs, replacement of the fixed turntable support base assembly, and troubleshooting takes approximately 3 hours. With the continuous increase in output from cold-rolled rewinding mills, the edge wire throughput of edge-coating machines remains high, leading to frequent jamming failures of the fixed turntable support base, which have caused several complete shutdowns, resulting in significant inconvenience for workers and substantial economic losses for production enterprises. Utility Model Content

[0006] This utility model proposes an anti-jamming turntable support for an edge rolling machine. By setting an edge thread retaining ring between the support and the flange of the shaft head, the edge thread is prevented from entering the support, thus solving the problem of jamming that easily occurs in existing edge rolling machine turntable support.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A fixed turntable support for an anti-jamming edge rolling machine includes a support base and a shaft head. The support base is rotatably connected to the shaft head via a bearing. A flange is provided on the outer circumferential surface of the shaft head. The flange and the end face of the support base are spaced apart to form a jamming zone. An edge thread retaining ring is provided in the jamming zone. The edge thread retaining ring is fixedly connected to the end face of the support base or the end face of the flange.

[0009] Furthermore, the edge thread retaining ring is fixedly connected to the end face of the flange.

[0010] Furthermore, the edge thread retaining ring is welded to the flange.

[0011] Furthermore, the outer diameter of the flange is smaller than the outer diameter of the support base, and the outer circumferential surface of the edge thread retaining ring is flush with the outer circumferential surface of the flange.

[0012] Furthermore, the distance between the edge wire retaining ring and the end face of the support seat is 2-4mm.

[0013] Furthermore, the thickness of the edge wire retaining ring is 3-5mm.

[0014] Furthermore, a lip seal is provided between the support base and the shaft head, and the lip seal is located on the side of the jamming area; a bearing cover is detachably installed on the end of the support base away from the flange.

[0015] Furthermore, the bearing cap is connected to the support base by a number of screws.

[0016] Furthermore, the material of the edge wire retaining ring is steel.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] 1. This utility model, by setting a thread retaining ring between the support base and the flange of the shaft head, prevents the thread from entering the support base and causing the shaft head to jam. It can effectively solve the problem of jamming that easily occurs in the fixed turntable support base of the existing edge rolling machine, ensure the safe operation of the equipment, reduce the workload of production workers and the economic losses caused by downtime for maintenance.

[0019] 2. In this utility model, the edge thread retaining ring is welded to the flange end face of the shaft head. The outer diameter of the flange is smaller than the outer diameter of the support base, and the outer circumferential surface of the edge thread retaining ring is flush with the outer circumferential surface of the flange. This can provide good shielding and protection for the jamming area and prevent the edge thread from winding on the edge thread retaining ring.

[0020] 3. This utility model has a bearing cover at one end of the support base and a lip seal at the other end to ensure the sealing of the support base and prevent dust in the air from entering the support base and contaminating the bearing, thereby increasing the bearing's frictional resistance.

[0026] Example 1

[0027] like Figure 3 As shown, a fixed turntable support for an anti-jamming edge rolling machine includes a support base 1 and a shaft head 2. The support base 1 is rotatably connected to the shaft head 2 via a bearing 7. A flange 3 is provided on the outer circumferential surface of the shaft head 2, and the flange 3 is spaced apart from the end face of the support base 1 to form a jamming zone 4. An edge thread retaining ring 5 is provided in the jamming zone 4, and the edge thread retaining ring 5 is made of steel. The edge thread retaining ring 5, the shaft head 2, and the support base 1 are coaxially arranged.

[0028] The threaded retaining ring 5 is fixedly connected to the end face of the support base 1 or the end face of the flange 3. In this embodiment, the threaded retaining ring 5 is fixedly connected to the end face of the flange 3; specifically, the threaded retaining ring 5 is welded to the flange 3. The outer diameter of the flange 3 is smaller than the outer diameter of the support base 1, and the outer circumferential surface of the threaded retaining ring 5 is flush with the outer circumferential surface of the flange 3. This arrangement provides good shielding and protection for the jamming area 4 and prevents the threaded wires from winding around on the threaded retaining ring 5.

[0029] The distance between the edge thread retaining ring 5 and the end face of the support base is 2-4mm, and the thickness of the edge thread retaining ring 5 is 3-5mm. In this embodiment, the distance between the edge thread retaining ring 5 and the end face of the support base is 3mm, the thickness of the edge thread retaining ring 5 is 4mm, and the width of the locking area 4 is 35mm, that is, the distance between the end face of the flange and the end face of the support base is 35mm.

[0030] In addition, a lip seal 6 is provided between the support base 1 and the shaft head 2, and the lip seal 6 is located on one side of the jamming area 4. A bearing cover 8 is detachably installed on the end of the support base 1 away from the flange 3. In this embodiment, the bearing cover 8 is connected to the support base 1 by several screws 9, which facilitates disassembly and assembly. This arrangement ensures the sealing of the inside of the support base 1 and prevents dust in the air from entering the support base 1 and contaminating the bearing 7, thereby increasing the frictional resistance of the bearing 7.

[0031] This invention provides a thread retaining ring 5 between the support base 1 and the flange 3 of the shaft head 2 to prevent the thread from entering the support base 1 and causing the shaft head 2 to jam. This effectively solves the problem of jamming that easily occurs in the fixed turntable support base 1 of the existing edge rolling machine, ensuring the safe operation of the equipment and reducing the workload of production workers and the economic losses caused by downtime for maintenance.
