1, OD
Detection methods:
Outside diameter size detection is usually used laser calibrator or photoelectric calibrator, they are different principles, but the realization of the function is basically the same, the photoelectric calibrator through the use of a variety of accessories and combinations to achieve a variety of types of rolled material OD dimensions and ellipticity of the detection.
Other inspection size applications:
In addition, through the use of eight-axis measuring head in the form of the internal diameter of the rebar, transverse ribs, longitudinal ribs, cross-section area, etc. on-line inspection.
The single-axis head can detect the rectangular cross-section width and thickness, square cross-section length, slit, bore diameter, height-position and other dimensions in addition to the diameter.
Applicable industries:
Wire and cable, rubber and plastic, round steel high wire, steel pipe, large diameter pipe can be tested.
2, width
Detection method:
Width measurement is usually photoelectric measurement (also laser measurement, machine vision measurement, etc.), according to the size of the plate is different, choose a different probe, commonly used at present there is a single probe, fixed-pitch double probe, pitch adjustable double probe three. Among them, the pitch-adjustable double probe is more flexible, can be adjusted by the measuring range to measure the width of different board width dimensions.
Applicable industries:
Applicable to a variety of materials, temperature of the plate detection, wood, foam, plastic, rubber, metal, steel, steel strip and so on.
3, thickness
Detection method:
Plate class thickness detection commonly used laser thickness gauge, its detection accuracy is higher, and can be detected on-line, in addition to the thin plate using ray thickness gauge, coated layer is used ultrasonic thickness gauge.
Applicable industries:
Water stopper, metal plate, hot and cold rolled sheet, wood, floor, cement board, rubber plate, plastic plate.
4, contour and surface defects
Detection method:
Contour measuring instrument uses laser detection principle to measure the contour of the measured object and the size of the surface defects, full-coverage measurements, the surface of the rolled material, such as folding, warping, pits, grooves, lugs and other defects can be detected.
Applicable industries:
Profile of any cross-sectional shape, such as round, square, rebar, hexagonal, railroad beam, T-type, H-type and other long materials.
5. Straightness
Two inspection methods:
One is the straightness inspection of rolled material surface, which is accomplished by three photoelectric measuring instruments;
One is the straightness inspection of the inner hole of the long pipe, which is detected by the laser principle.
Applicable industries:
Separately applicable to
online diameter and straightness inspection of metal bars, tubes, ceramic tubes, etc.
Straightness inspection of inner bore axis of seamless steel tubes and other tubular materials.
6, length
Detection method:
The length gauge is a machine vision based inspection equipment, through multiple industrial cameras for length detection.
Applicable industries:
Hot rolled bars, steel pipes, metal bars, tubes and so on.
7, inside diameter
Detection method:
The inside diameter measuring instrument is based on the laser principle of detection, but because the probe has to be inserted inside the pipe, the inside diameter of the pipe to be measured has to be large.
Applicable industries:
Only offline inspection of the inner diameter of large diameter pipes, tubes, etc. at the end of the pipe.
8, wall thickness
Two detection methods:
Wall thickness gauge is also based on the laser measurement principle, only detect the wall thickness of the pipe end, can go deep into the range of 1m, the same only detection of large-diameter pipe;
The detection method based on two photoelectric measuring instrument, one detects the size of the inner core, one detects the size of the finished product, and the calculation can be obtained through the calculation of the wrapped inner core wall thickness Size.
Applicable industries:
Subject to
Large-diameter pipes, tubes, etc.
Insulation layer thickness testing of cables and cables, etc., respectively.
9, bore
Inspection method:
Bore measuring instrument based on machine vision and parallel source for the detection of bore.
Applicable industries:
Measurement of internal holes of small parts, such as round holes, square holes, hexagonal holes, and other hole characteristics detection, applicable to wire drawing molds, cable molds, and so on.
10, curvature
Detection method:
Curvature Measuring Instrument is based on the laser principle of on-line testing equipment. It can detect the head distance change of bending during the test of bimetal sheet.
Applicable industries:
Bimetal sheet and so on.
