Abstract

The invention provides a pull rod connection structure in a short-stress path rolling mill. The pull rod connection structure comprises a hollow shaft. A shaft head of a pull rod is located in the hollow shaft. The shaft head and the hollow shaft are connected through a key. Key grooves are formed in the surface of the shaft head and the inner wall of the hollow shaft correspondingly. The shaft islocated in the key grooves. The upper end of the shaft head is detachably connected in the hollow shaft through a connection component. A regulation component is installed between the lower end faceof the hollow shaft and a shaft body of the pull rod. The regulation component can be used for adjusting the distance between the lower end face of the hollow shaft and the end face of a shaft shoulder of the shaft body. The problem of the connection difficulty caused by installation and machining deviation can be well solved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for short stress line rolling mills, and in particular relates to a tie rod connection structure in short stress line rolling mills. Background technique [0002] When assembling the short stress line rolling mill, the pressing device is directly installed on the plane composed of multiple tie rods in the roll train. The two boxes of the pressing device are respectively installed on the operation side and the transmission side of the roll train. The tie rods in the roller system are connected. In the actual processing and assembly process, there are processing deviations in the size of each part. The processing deviations of each part accumulate together to make the surface of the multiple tie rods installed with the pressing device inconsistent. Therefore, when When the pressing device is assembled, the boxes on both sides are not on the same plane, and the coupling cannot connect the...
