Abstract
The utility model discloses a combined transmission-typed three-roll tension reducing mill, belonging to seamless steel pipe production equipment. The combined transmission-typed three-roll tension reducing mill comprises a motor, a reducer and a roller frame (1); the reducer consists of three independent parts in parallel: a concentrated differential seed transmission part (2), a single transmission part (8) and a single-motor concentrated fixed speed-ratio transmission part (7); the input end of the concentrated differential speed transmission part (2) is provided with a main motor (3) and a superposition motor (4); the output end of the concentrated differential speed transmission part (2) is provided with 4-20 roller frames; the input end of the single transmission part (8) is provided with a motor (5); each motor drives a roller frame by a single transmission reducing mechanism; the input end of the single-motor concentrated fixed speed-ratio transmission part (7) is provided with a motor (6) and the output end thereof is provided with 2-4 frames. The combined transmission-typed three-roll tension reducing mill can smartly roll the steel pipes with various grades and can realize the quality control to the rolled steel pipes.
Description
Technical field
The present invention relates to a kind of seamless steel pipe production, the three-roller tension reducing mill in particularly a kind of seamless steel pipe production.
Background technology
The kind of drive of the roll in the existing three-roller tension reducing mill is single, can not adjust rolling mode according to the conversion that requires of product rolling mill practice flexibly, the steel pipe of rolling different cultivars needs different three-roller tension reducing mills to realize, cause equipment investment big, the production cost height, a kind of stretch-reducing mill that can satisfy different steel pipe rolling requirements simultaneously of market in urgent need.
Summary of the invention
The kind of drive that the invention solves the roll in the existing three-roller tension reducing mill is single, can not adjust the technical problem of rolling mode according to different roll seamless steel tube technological requirement flexible transformation.
The present invention is achieved by following scheme:
Combined driving type three-roller tension reducing mill comprises motor, reductor, roll stand 1, and reductor concentrates 7 three independent sectors of fixed speed ratio running part to form side by side by concentrated differential running part 2, independent running part 8 and single motor; Concentrate the input of differential running part 2 to be provided with main motor 3 and superimposed motor 4, concentrate the output of differential running part 2 to be provided with 4-20 roll stand; Running part 8 is made up of one group of driver separately, and the input of every driver is provided with a motor, and the output of every driver and a roll stand link together; Single motor concentrates the input of fixed speed ratio running part 7 to be provided with motor 6, and single motor concentrates the output of fixed speed ratio running part 7 to be provided with 2--4 frame.
The output of described concentrated differential running part 2 is provided with 12 roll stands, and these frames can have different mill speeds according to the various combination of main motor 3 and superimposed motor 4; The output of described independent running part 8 is provided with 10 rolling-mill housing; Described single motor concentrates the output of fixed speed ratio running part 7 to be provided with 2 frames.
The invention has the beneficial effects as follows and realized a tractor serves several purposes, realized the pipe end of rolled steel tube is thickened control that the steel pipe of rolling various kinds and realization are to the quality control of rolled steel tube flexibly.
