Long guide roller outlet table for tube rolling machine

Abstract

The invention provides a long guide roll typed outlet platform used in a tube mill, relating to an outlet platform of a hot tube mill. The outlet platform of the traditional tube mill adopts three rolls holding unit to limit the waggle of a steel tube; as the volume of the three rolls holding unit is large, only the centralized drive of a single motor can be adopted, therefore, the weight of an outlet platform device and the motor power are great; in addition, as a high-temperature pierced billet runs through the middle of a reducer, the working environment is bad, thereby reducing the service life of the reducer and limiting the diameter size of the pierced billet. The invention is formed by a lifting base, an upper press roll, a V-shaped press roll, two sets of long guide rolls provided with transmissions, a lifting beam and a lifting live-roller table, wherein, the lower part of the lifting beam is provided with a lifting base device, while the upper part is provided with a long guide roll device with a backup roll driven by the motor, an upper press roll device and a V-shaped press roll device, and the middle of the two long guide rolls is provided with a lifting live-roller table device. The outlet platform has the advantages of compact structure, low cost, major-diameter and high-strength steel tube rolling applicability, etc.

Description

technical field [0001] The invention relates to a hot-rolled pipe mill, in particular to the hot-rolled pipe mill outlet equipment of a seamless steel pipe production unit. Background technique [0002] Hot-rolled pipe is the most important process in the production of seamless steel pipe, and it is the main process that undertakes metal deformation. The role of the hot rolling mill in the seamless steel pipe production unit is to produce the required blank pipe through rolling to reduce the diameter and wall of the capillary pipe after the piercer is pierced. The tube rolling process is as follows: the capillary coming out of the piercer is placed on the rotating roller table of the exit table of the piercer, and then the manipulator of the capillary traverse device takes the capillary away, and moves in parallel and puts it on the pre-threading roller table in front of the entrance table. At this time, after cooling The mandrel is lubricated and penetrated into the capill...

AI Technical Summary

Problems solved by technology

Therefore, the equipment weight and motor power of the exit station are relatively large, which makes it difficult for the pipe rolling mill to roll large-diameter and high-strength steel pipes, and limits the development of the pipe rolling mill.

Moreover, the high-temperature waste pipe has to pass through the middle of the transmission reducer, and the working environment is harsh, which greatly reduces the life of the reducer, and also limits the diameter of the waste pipe to not be too large
