Description

Combined wrench for high-speed wire rod roll neck

Technical Field

The utility model relates to the technical field of combined wrenches, in particular to a combined wrench for a high-speed wire rod roll neck.

Background

The roll neck spanner is a special tool necessary for on-site roll installation, and the roll neck flat heads are different in size due to different roll diameters of the rolls. At present, the rough and medium rolling roller of the high speed line of the horse steel and special steel has three types which are respectively: model 450, model 550 and model 680. Therefore, the special spanner for the flat head of the roll neck is also divided into three types (see e, f and j in figure 2) and corresponds to various types of rolls. A roller loading process: before a steel rolling operator installs a roller, firstly, a roll neck flat head and a motor are connected to drive a groove of an inner hole of a universal shaft to be adjusted to a horizontal plane, and the groove of the universal shaft and the flat head face are kept in horizontal consistency. Secondly, the universal shaft extends to the flat head of the roll neck of the roll under the pushing of the hydraulic oil cylinder, and the universal shaft is connected into a mutually matched whole (see a and c in figure 1), so that the whole roll loading process is completed. After the roller is connected with the universal shaft, steel rolling is realized under the action of a motor transmission shaft. Because motor drive major axis and cardan shaft are comparatively heavy, artifical rotatory strength is limited, and operative employee can only rotate the fine setting to the flat head of roll neck to cardan shaft hole recess is the benchmark, at this moment, and the flat head of rotatory roll neck needs a special spanner, we call: a roll neck wrench.

At present, when the roll is installed in steel rolling branch plants every time, a roll neck spanner is needed to manually rotate and finely adjust the roll. If a plurality of rollers or three different types of rollers are replaced in a short time, different types of neck wrenches are required. Sometimes, the phenomenon that the roll neck wrenches are not enough and are mutually taken by mistake often occurs, and the operation is very inconvenient. Whether a universal 'combined' roll neck spanner can be designed, only one roll neck spanner is needed, the problems of multiple roll changes, multiple models, messy taking and placing can be solved, the field operation is convenient, and the requirements of field 'lean management' are met.
