Description

Technical Field

[0001] The utility model belongs to the technical field of high-speed wire rod rolling mills, and in particular relates to an elliptical hole-type pinch roller ring of a high-speed wire rod rolling mill. Background Art

[0002] The existing roller rings basically need to be used in conjunction with different roller shafts during the manufacturing and subsequent processing. At the same time, the roller rings and the roller shafts are basically connected by a heat-fitting method, so that the roller rings are finally driven to rotate by the roller shafts and then processed. The heat-fitting method is used to connect the roller rings with roller shafts of different diameters, which is time-consuming and labor-intensive. At the same time, it is also difficult to disassemble, which reduces work efficiency and has certain inconveniences in the overall design.

[0003] The existing roller rings are limited in their processing of high-speed wire rods with a specification of ф16.3mm, and cannot match the Morgan's fifth-generation high-speed wire rod mill to ensure stable and smooth production, and are not in line with the model of the Morgan's fifth-generation high-speed wire rod mill.

[0004] In view of the above factors, the present invention provides an elliptical hole pinch roller ring for a high-speed wire rolling mill, which adopts a separate and detachable structure, is easy to repair and replace, can be replaced on site, has a long service life, low production cost, and a wide range of practical applications.

[0030] like Figure 1-4As shown, an elliptical groove pinch roll ring for a high-speed wire rod rolling mill includes a pinch roll ring 1 and roll shaft supports 2 symmetrically arranged on both sides of the pinch roll ring 1. One side of the roll shaft support 2 is detachably connected to the feed roll ring 1, and the end of the roll shaft support 2 away from the feed roll ring 1 is detachably connected to the roll shaft 3.

[0031] The pinch roller ring 1 is provided with a ring hole structure 4 that contacts the circular rolled piece. The pinch roller ring 1 is provided with an inner hole 5 , and a roller ring support sleeve 6 is installed along the axial direction of the inner hole 5 .

[0032] In order to ensure a certain clamping force and holding function for the rolled piece while minimizing the indentation on the rolled piece during use, the pinch roller ring 1 is provided with a ring hole structure 4 in an elliptical hole shape that contacts the circular rolled piece, and the elliptical holes on the pinch roller ring 1 are arranged at intervals.

[0033] In order to facilitate the axial rolling stress borne by the roller ring end 7 during rolling in use, roller ring ends 7 are provided at both ends of the feed roller ring 1. The width of the roller ring end 7 is greater than 3-4 times the width of the elliptical hole profile, and the roller ring end 7 is integrally formed with the feed roller ring 1.

[0034] In order to facilitate detachable replacement in use, a sleeve that cooperates with the roller ring end 7 is fixedly provided on one side of the roller shaft bracket 2;

[0035] The diameter of the roller ring end 7 is matched with the shaft hole of the shaft sleeve on the roller shaft support 2. The upper and lower ends of the roller ring end 7 are provided with positioning holes 8. The positioning holes 8 are matched with the bolt positioning holes 9 opened on the shaft sleeve on the roller shaft support 2 and are fixed by bolts.

[0036] When in use, the roller support 2 can be replaced with a different model to match the pinch roller ring 1 with different diameters to meet the needs of use.

[0037] To facilitate detachable replacement during use, the roller support 2 has a roller 3 screwed to the end away from the feed roller ring 1. The roller 3 at one end of the roller support 2 is connected to the drive system of the Morgan Fifth Generation High-Speed ​​Wire Mill (not shown in the prior art figures), while the roller 3 at the other end of the roller support 2 is connected to the bearing bracket of the Morgan Fifth Generation High-Speed ​​Wire Mill (not shown in the prior art figures).
