Description
Technical field
A kind of steel band production equipment is the utility model is related to, more particularly, to a kind of steel band straightener.
Background technology
Band flattened or straightening process in need to do the real-time detection of elongation percentage, current detection method is mainly
Laser velocimeter elongation percentage detects, and the mechanism performance is good, and accuracy of detection is outstanding, but price is high, and is completely dependent on import, and one
Set is about high in RMB 300,000 or so, use cost.In the relatively low occasion of some required precisions, generally use encoder
Elongation percentage is detected, but common practice is installed in slewing rollers top, or utilize the speed measuring coder behind driving motor
Data.Way installed in slewing rollers end, because not by reductor speed than amplified signal quantity, generally detection essence
Spend it is poor, for example, turn to 600 millimeters of roller diameter, using high line number 4000 line coding devices measure, 600*3.1415926/4000
=0.4712mm/p, resolution ratio 0.47/1000, but, it is necessary to control or accuracy of detection 1/ in steel band production process
1000-5/1000, this resolution ratio can not meet detection control and require, also be not excluded for detecting caused by interference signal
Error, if 1-2 pulse signal disturbs, substantially this testing result is just without reference to meaning.And slewing rollers exist
Grinding skin again is needed after damaged surfaces, diameter is changed grinding skin later, and all reference datas are all lost,
The elongation percentage measured can be sayed without any accuracy.Another is to use driving motor code device signal, resolution ratio
Amplify by reductor, substantially met testing requirements, but the fast ratio error of reductor, the diameter grinding change of live-roller are same
Sample has a strong impact on detection data.It is larger all with actual elongation percentage deviation using the measurement data of above-mentioned detection mode elongation percentage.
Utility model content
The applicant is directed to the problem of above-mentioned, has carried out Improvement, there is provided a kind of steel band straightener, improve elongation percentage
Real-time testing agency, simple and compact for structure, manufacturing cost and use cost is low, and diameter changes after avoiding slewing rollers grinding skin
Influence to accuracy of detection, elongation percentage detection are accurate, it is ensured that product quality.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：
A kind of steel band straightener, including frame, entrance S rollers and outlet S rollers are arranged in the frame, and straightening mechanism is set
In the frame between the entrance S rollers and the outlet S rollers, two sets of elongation percentage measuring mechanisms be separately positioned on it is described enter
The side of mouth S rollers and the outlet S rollers；The elongation percentage measuring mechanism is fixedly installed in the frame including level and performs gas
Cylinder, the piston rod connecting spring hold-down mechanism of the execution cylinder, nylon wheel are rotatably connected the spring compression mechanism, coding
Device is arranged on the nylon wheel, and during detection, the nylon wheel of two sets of elongation percentage measuring mechanisms is pressed on around described respectively
The steel strip surface of entrance S rollers and the outlet S rollers.
Further：
A diameter of 60 millimeters of the nylon wheel.
It is of the present utility model to have technical effect that：
A kind of steel band straightener disclosed in the utility model, the real-time testing agency of elongation percentage is improved, it is straight using nylon wheel
Connect and be pressed on steel strip surface for detecting elongation percentage, simple and compact for structure, manufacturing cost and use cost is low, avoids slewing rollers grinding table
The influence that diameter changes to accuracy of detection after face, elongation percentage detection are accurate, it is ensured that product quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes frame, entrance S rollers 2 and outlet S rollers 4 are arranged in frame, straightening mechanism 3
It is arranged in the frame between entrance S rollers 2 and outlet S rollers 4, the first elongation percentage measuring mechanism 1 is arranged on the side of entrance S rollers 2,
Second elongation percentage measuring mechanism 5 is arranged on the side of outlet S rollers 4.First elongation percentage measuring mechanism 1 and the second elongation percentage measuring machine
Structure 5 is fixedly installed on execution cylinder 7 in frame including level respectively, the piston rod connecting spring hold-down mechanism 8 of execution cylinder 7,
Nylon wheel 9 is rotatably connected spring compression mechanism 8, and encoder is arranged on nylon wheel 9, and steel band 6 bypasses entrance S rollers 2, by rectifying
Straight mechanism 3, and around outlet S rollers 4, in detection, the nylon wheel 9 of the first elongation percentage measuring mechanism 1 is pressed on around entrance S rollers
On 2 surface of steel band 6, the nylon wheel 9 of the second elongation percentage measuring mechanism 5 is pressed on the surface of steel band 6 around outlet S rollers 4, Buddhist nun
Dragon wheel 9 diameter can according to be actually needed determine, in the present embodiment, a diameter of 60 millimeters of nylon wheel 9.
In the utility model using diameter 60mm super abrasive nylon wheel elongation percentage measuring mechanism, nylon wheel is a diameter of
60mm, encoder line number are the conventional coders of 2000 lines, in order to prevent nylon wheel 9 skids from using spring compression mechanism, in order to
Prevent band plumb joint from damaging nylon wheel, execution cylinder 7 is as Kuai Tai mechanisms, the operable execution when predicting band and having plumb joint
Cylinder 7 makes nylon wheel leave strip surface.During detection, the nylon wheel for detection directly bears against steel strip surface, with 1 meter of work of length
For calculating cycle, 2000*1000/ (60*3/1415926)=10610 (p) resolution ratio is 1/10000, can meet testing requirements.
If necessary to improve precision, high line number encoder may be selected in encoder, and resolution ratio can reach 1/30000, fully meet detection
It is required that 1-2 pulse of signal disturbance, precision influences 1/10000, same to meet inspection far below the 1/1000 of detection necessary requirement
Survey and require.
