SU1280510A2 - Device for coordinate marking of flaws - Google Patents

Abstract

The invention relates to the field of automated non-destructive quality control of rolled metal overhead rotary converters; and is an improvement to the device auth.St. No. 1004862. The purpose of the additional invention is to ensure the rational cutting of products according to the results of control by applying specific paint marks on the surface of the product to defect-free areas of the product. The coordinate flaw device consists of a switch 1 of flaw detectors, a transfer 2 block, information about defects, 3 sensors, 4 clock pulses, a defect-measuring control block 5, a defect-measuring block 6, a flaw detector 1 1, and a logic circuit for coding the level of detected defects. The device provides a mark on the surface of the controlled product (with the same defect-testers) by marking when there are repaired items (defects, defective defects (final), as well as a specific mark of a defect-free area of at least a predetermined value L. 1 Il.

Description

N) The invention relates to flaw detection methods for lengthy products, can be used in conjunction with automated installations, which include a flaw detector with rotating, converters, and: a device for the coordinate elevation of defective places, and is an additional one to the main auth. No. 1004862, the whole of the invention is to ensure

 rational cutting of products according to the results of their control, due to the fact that in addition to marking the controlled product with marks of repaired defects and defects, a specific mark of the defect-free area is carried out.

The outline shows the functional scheme of the coordinate flaw detection device.

The coordinate flaw device contains a channel switch of defectoders connected in series, an N-channel unit 2 for transferring information about defects with successively switched sensors 3 and 4 clock pulses, a unit of control of defectometers and a unit of 6 defect testers that includes N defecto-meters located along the perimeter of the monitored products with equal distances in the sector among themselves.

The device includes a multivibrator 7 connected in series to the input of the switch t, a first pulse front and back edge selection circuit 8, a single-pulse shaper 9 with adjustable pulse duration and a three-input first element 10 OR, the second input of which is connected to flaw detector output 11 Repair. In addition to TorOs, the device includes in series the sensor 12 for the presence of the product in the control zone, the second pulse-front separation circuit 13, the second IGSh element 14, the counter 15 and the driver 16, the output of the latter is connected to the third input of the first element 10 1-ШИ, while one from the inputs of the second element 14ShSh connected to the output of the standby multivibrator 7, and the counting input of the counter 15 is connected to the sensors 3 and 4 clock pulses.

The device coordinate flaw works as follows.

ka 6 flaw detectors in accordance with the angular coordinate of the detected defects, i.e. generates signals to mark the defects being repaired along one of the N surface forming products of the product, continuous, corresponding to the length of the defect, with a longitudinal mark.

The signal from the N outputs of the switch 1 is transferred by the information transfer unit 2 from the control plane to the N plane of the defect meters of block 6 synchronously with the movement of the product under test. The synchronism of the transfer is provided by pulses from the sensors 3 and 4 clock pulses arranged in series along the path of the product and respectively included in the work. After the information transfer unit 2, the signals are amplified in power in the unit 5 of the control of the defectometers and are fed to the unit 6 for powering the detectors.

When a defective defect is detected, signals from the output of the flaw detector 11 Marriage arrive on. input of the waiting multivibrator 7 with repeated request. The waiting multivibrator 7 converts the pulses (a burst of pulses) from a defect into a single rectangular pulse, the duration of which is equal and proportional to the length of the defect.

From the output of the inflatable multivibrator 7, a rectangular pulse arrives at the first pattern 8 of the selection of the leading and trailing edges of the pulses. At the output of the first circuit 8, two short pulses are formed, corresponding to the beginning and end of the defect, which are fed to the input of the one-vibrator-former 9. The pulses from the one-vibrator 9 through the first element 5 of 10 RSHIs enter the input of the repaired defects of the switch 1 of the defectometers, i.e. On the same input, a compiler Iytapat 1, which receives pulses from the flaw detector channel 11 Flaw detector 1 1 signals from repaired 1 x defects through the unbinding first element 10 1-ШН to the input Repaired defects of the switch 1 of the flaw detectors. Switch 1 generates rectangular pulses of them with a duration proportional to the length of the defect and distributes these pulses over N channels (for N-defect-meters)
