Problems solved by technology

[0003] Most of the existing steel rolling guide devices are integral (Duan Jianping, Zhang Youwen. Development and improvement of rolling mill guide devices [J]. Machinery Management Development, 2001, 17-19.), that is, the diameter of the hole that restricts the passing of the rolled piece is fixed. The rolling guide device is only suitable for a specific pass type, which has no versatility and increases the production cost
Moreover, once a certain part of the rolled steel guide device is damaged, the entire device cannot be used and needs to be replaced as a whole

Abstract

The invention relates to a guide and guard device for rolling of profile steel with a special-shaped section. According to the technical scheme, fixed sliding blocks (7) on the two sides of a guide and guard supporting plate (2) are mounted in vertical strip-type regulating holes (5) of corresponding supports (1), the guide and guard supporting plate (2) is fixedly connected with the supports (1) through threaded rods (8) and nuts, and a guide and guard device body (3) is mounted at the middle position of the upper plane of the guide and guard supporting plate (2). A lower baffle (11) is mounted between the lower portions of two guide plates (14). Upper baffles (10) are correspondingly mounted between the upper portions of the two guide plates (14). The two guide plates (14) are arranged symmetrically. The two upper baffles (10) are connected with the corresponding guide plates (14). Side wing plates (13) are symmetrically mounted on the outer sides of the two guide plates (14). Guiding plates (12) are symmetrically mounted on the front sides of the two guide plates (14). A strip-type regulating block on the lower plane of each side wing plate (13) is mounted in a strip-type guide and guard regulating hole (6) in the guide and guard supporting plate (2). The side wing plates (13) are fixedly connected with the guide and guard supporting plate (2) through bolts. The guide and guard device has the advantages of being simple in structure, low in cost, convenient to maintain and high in universality.

Description

technical field [0001] The invention relates to the technical field of a steel rolling guide. In particular, it relates to a guide device for rolling special-shaped section steel. Background technique [0002] At present, with the acceleration of the social process and the deepening of urbanization, the demand for steel is constantly increasing. During the rolling and forming process of steel, the rolled piece is prone to defects such as torsion and bending, which affects the performance of the steel product and reduces the production efficiency of the steel. Therefore, by installing a suitable rolling guide device at the entrance of the rolling mill, technicians can reduce the above-mentioned defects, improve the yield of steel products and reduce the waste of raw materials. [0003] Most of the existing steel rolling guide devices are integral (Duan Jianping, Zhang Youwen. Development and improvement of rolling mill guide devices [J]. Machinery Management Development, 20...
