Abstract
The invention discloses electric moving type dance roll tension adjusting equipment for cold-rolling strip steel. The electric moving type dance roll tension adjusting equipment comprises a rack, chain wheels, a chain, a dance roll, a turning roll and a tension detecting device. The chain wheels are symmetrically arranged on the two sides of the rack, and one chain wheel is driven by a forward and reverse rotating motor which is connected with the corresponding chain wheel through a speed reduction driving device. The turning roll is arranged above one chain wheel, and the turning roll is connected to the rack through a supporting column. The chain wheels on the two sides of the rack are connected through the chain, and the dance roll is arranged between the two chain wheels. The dance roll is connected with the chain through a mounting seat, and the dance roll is connected with the rack through a moving seat and can move along a rail on the rack. The cold-rolling strip steel is output by the turning roll via the dance roll, and the tension detecting device is arranged on the turning roll and is used for detecting the tension of the cold-rolling strip steel.

Description
Technical field
The present invention relates to cold-strip steel tension adjustment technical field, particularly relate to a kind of cold-strip steel electrical moving dancer roll tension adjustment equipment.
Background technology
On large high-speed continuous belt steel process line, very strict to the tension force control overflow of band steel, especially require the stability contorting of strip tension in stove, because run under the hot conditions of steel band in annealing furnace, the plasticity of steel band obviously increases, and this causes steel band sectional area to shrink, narrowed width.Practical operation experience shows, under fixing tension, the steel band value that narrows in stove increases with furnace temperature rising.For avoiding at high temperature sectional area shrink excessive or broken belt accident occurs, in steel band heating process, suitably should change the tension force of steel band with the raising of temperature of steel strips.Reach this purpose, the jockey pulley depended alone before and after stove controls to be inadequate, usually requires that arranging special plant equipment controls stove internal tension and compensate.Dancer roll is exactly so a kind of special equipment.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of cold-strip steel electrical moving dancer roll tension adjustment equipment, structure is simple, easy to operate, solve band steel tension force when stove internal cause temperature raises or reduce and cannot carry out the problem controlling and compensate, improve the quality of production and production efficiency.
A kind of cold-strip steel electrical moving dancer roll tension adjustment equipment that the present invention proposes, comprises frame, sprocket wheel, chain, dancer roll, slewing rollers and tension detecting apparatus; Sprocket wheel is symmetricly set on frame both sides, and one of them sprocket wheel is driven by clockwise and anticlockwise motor, and clockwise and anticlockwise motor is connected with sprocket wheel by speed reducing driving device; Be provided with slewing rollers above one of them sprocket wheel, slewing rollers are connected in frame by support column; The sprocket wheel of frame both sides is connected by chain, dancer roll is arranged between two sprocket wheels, dancer roll is connected with chain by mount pad, dancer roll is connected with frame by Mobile base also can along the rail moving in frame, cold-strip steel is exported through dancer roll by slewing rollers, and tension detecting apparatus to be arranged on slewing rollers and to detect the tension force of cold-strip steel.
Preferably, clockwise and anticlockwise motor and slewing rollers are positioned at frame the same side.
Preferably, clockwise and anticlockwise motor and slewing rollers lay respectively at frame both sides.
Preferably, mount pad, dancer roll coaxially arrange and are arranged on Mobile base, and mount pad is rotatably connected on Mobile base, and Mobile base is provided with the roller in the track that is placed in frame.
Preferably, the tightness for adjusting chain in frame is movably arranged on away from another sprocket wheel of positive and negative motor-driven sprocket wheel.
A kind of cold-strip steel electrical moving dancer roll tension adjustment equipment provided by the invention, solve band steel tension force when stove internal cause temperature raises or reduce and cannot carry out the problem controlling and compensate, in-furnace temperature reduces band steel and shrinks the strip tension increasing causing tension detecting apparatus to detect, positive and negative Electric Machine Control sprocket rotation realizes band steel and is pulled left by dancer roll, the strip length of dancer roll release compensate for band steel Yin Wendu to be reduced and the length of shortening, keeps strip tension constant; When in-furnace temperature raises, band steel extends the strip tension causing tension detecting apparatus to detect and reduces, and dancer roll moves right under the driving traction of positive and negative motor, absorbs strip length, keeps strip tension constant; Thus improve the quality of production.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cold-strip steel electrical moving dancer roll tension adjustment equipment that the present invention proposes.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is the structural representation of a kind of cold-strip steel electrical moving dancer roll tension adjustment equipment that the present invention proposes.
With reference to Fig. 1, a kind of cold-strip steel electrical moving dancer roll tension adjustment equipment that the present invention proposes, comprises frame 1, sprocket wheel 2, chain 3, dancer roll 4, slewing rollers 5 and tension detecting apparatus 6; Sprocket wheel 2 is symmetricly set on frame 1 both sides, and one of them sprocket wheel 2 is driven by clockwise and anticlockwise motor 9, and clockwise and anticlockwise motor 9 is connected with sprocket wheel 2 by speed reducing driving device, and another sprocket wheel 2 is movably arranged on the tightness for adjusting chain 3 in frame 1.Be provided with slewing rollers 5 above one of them sprocket wheel 2, slewing rollers 5 are connected in frame 1 by support column 7, and clockwise and anticlockwise motor 9 and slewing rollers 5 lay respectively at frame 1 both sides.The sprocket wheel 2 of frame 1 both sides is connected by chain 3, dancer roll 4 is arranged between two sprocket wheels 2, dancer roll 4 is connected with chain 3 by mount pad 41, dancer roll 4 is arranged on the middle part of frame 1 by Mobile base 42, mount pad 41, dancer roll 4 coaxially arranges and is arranged on Mobile base 42, mount pad 41 is rotatably connected on Mobile base 42, Mobile base 42 roller be provided with in the track that is placed in frame 1 makes dancer roll 4 can along the rail moving in frame 1, cold-strip steel 8 is exported through dancer roll 4 by slewing rollers 5, tension detecting apparatus 6 to be arranged on slewing rollers 5 and to detect the tension force of cold-strip steel 8.
