Description
Technical field
The present invention relates to a kind of method of the acquisition with steel burr and shape wave data more particularly to a kind of pair of strip end face burrs
The method for carrying out data acquisition with shape wave.
Background technique
For silicon steel strip in edge shearing production process, edge burr and shape wave and developed width are silicon steel strip qualities
Important factor for controlling.Strip steel edge burr and shape wave should control in reasonable range, if the size of burr and shape wave
It has been more than range, has been formed the mass defect of strip.Meanwhile the developed width of strip must also be examined and compound, with
Ensure to meet the requirement of dimensional tolerance.
Strip steel edge burr have substantially divide it is several：Successional burr is overproof；The burr of intermittence is overproof and has bright spot (white
Point)；Small flange or wrinkle.
Strip steel edge burr Producing reason substantially there are two types of, one is the burr generated in the operation of rolling, this burr
Often with the side wave flaw of steel edge portion；Another kind be in edge shear history, due to shearing formed edge burr,
This burr is concentrated mainly on the region within the edge 10mm of strip.Steel edge portion is sheared under normal shearing condition, up and down
There are certain gap between roller shears, different gap width settings will lead to different burrs, and the smaller burr in gap is smaller；It cuts
When cutting, the registration of cutter should be not more than the half of steel strip thickness, and under normal shearing condition, registration is better, and burr is smaller.
For the influence of equipment repeatable accuracy, often there is the overproof problem of edge burr when loading and unloading cutter and adjustment equipment.
The essence of strip edge wave is that the transient force as suffered by some regions of strip edge has been more than bending for strip material
It takes intensity and leads to local plastic deformation, external force deforms and can not restore after disappearing, and appearance is side wave.In actual production process
In, edge burr caused by being sheared by edge and shape wave often occur, and become the major reason for leading to steel defect.
Influence in order to avoid burr and edge shape wave to strip quality, silicon steel production line in process of production, can be to lifes
Finished product is sampled detection, i.e., the template of about 1 meter of length is sheared on the head of strip, and to template edge burr and shape wave
Carry out offline inspection.
It is existing that upper surface progress data acquisition of the measuring instrument to strip is mainly passed through to the mode detected with steel burr, but
The direction for being burr in actual conditions is dispersion, is likely in upper surface, lower surface and side end face there are burr, existing
Measurement is acquired only for the data of one side, not high to strip information data precision collected, there is very big error,
It is unable to reach the requirement of strip factory.
Summary of the invention
Present invention aim to address the problems of the prior art, one kind is provided treats measuring tape steel and detected, and pass through
