Description

Technical Field

[0001] This utility model relates to an end cap structure, and more particularly to an end cap structure for a winding machine drum. 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. A coiler generally consists of a main coil shaft, auxiliary coiling rollers, and support end caps, with the support end caps fixed to one end of the main coil shaft. During the coiling process, the product is primarily formed on the main coil shaft, which is typically driven by a motor. The auxiliary coiling rollers are also usually driven by a motor, and a hydraulic cylinder drives the rollers to move, facilitating smooth coiling.

[0003] The existing fixing method between the support end cap and the drum spindle is shown in the attached diagram of the instruction manual. Figure 1 As shown, an assembly groove is provided on the support end cap, one end of the drum spindle is inserted into the assembly groove, and a threaded mounting hole is provided on the support end cap. The support end cap and the drum spindle are axially fastened by four fixing bolts.

[0004] The existing fixing method has the following shortcomings in use. It uses four fixing bolts for axial fastening. During the steel strip rolling process, the fixing bolts are subject to circumferential shear force, which can easily cause problems such as loosening, bolt breakage, and damage to the bolt bottom hole. This can cause the rolling mill to stop and affect production. In some cases, the rolling mill roll may even become unusable and have to be replaced entirely, which restricts the safe and stable production of the rolling mill. Therefore, it is of great significance to improve the positioning performance of the support end cap and improve its operational stability. Summary of the Invention

[0005] This utility model addresses the shortcomings of existing technologies by providing a winding machine drum end cap structure.

[0006] This utility model is achieved through the following technical solution: a winding machine drum end cap structure is provided, including an end cap body, a positioning member, and a winding drum spindle. A connecting slot is provided at one end of the end cap body, and one end of the winding drum spindle is inserted into the connecting slot and interference-fitted with the connecting slot. The winding drum spindle and the end cap body are fixed by a first connecting mechanism. The positioning member is fixedly installed at the center of the connecting slot and is embedded in the square inner hole at the center of the winding drum spindle to perform circumferential positioning of the winding drum spindle.

[0007] Preferably, a square positioning block integrally formed with the end cap body is provided at the center of the connecting slot; the positioning component includes a connecting plate and a square positioning sleeve, the square positioning sleeve is fixedly connected to the connecting plate, and a square positioning hole that mates with the square positioning block is provided on the connecting plate, the square positioning block is inserted into the square positioning hole.

[0008] Preferably, the square positioning sleeve is inserted into the square inner hole at the center of the drum spindle and the square positioning sleeve and the square inner hole are interference fit.

[0009] Preferably, the positioning element and the end cap body are fixed by a second connecting mechanism.

[0010] Preferably, the second connecting mechanism includes four connecting bolts, four mounting holes on the connecting plate, and an inner connecting hole corresponding to each mounting hole on the end cap body. Each mounting hole and its corresponding inner connecting hole are fixed by connecting bolts.

[0011] Preferably, the first connecting mechanism includes four fixing bolts, four external connecting holes on the end cap body, and assembly holes corresponding to each external connecting hole on the drum spindle. Each external connecting hole and its corresponding assembly hole are fixed by fixing bolts.

[0012] The beneficial effects of this utility model are as follows: This application fixes the end cap body, positioning component, and drum spindle into a tightly fitted structural whole. Through the cooperation of square positioning block and square positioning hole, as well as square positioning sleeve and square inner hole, circumferential positioning and axial fixation can be achieved. The positioning component bears most of the circumferential shear force, thus greatly reducing the circumferential shear force on the first connecting mechanism and significantly improving the structural strength of the support part.
