Specimen drawing system for Tin coated steel plate defect tester

摘要

The invention test assembly drawing apparatus that enables by using a squeeze for applying the force so that the specimen is drawn while moving along the two opposite sides fixed to the taut state the specimen so that the overall testing process can take place in a plane, automated and unmanned of the testing device for it is an object to provide.; Test samples are drawn device of the present invention, the specimen 20 is, and two tension rollers 21 and 22 for fixing the both ends thereof, respectively to maintain a taut condition, is located between the tension rollers (21, 22) and the upper and lower and a bed (23) configured to be movable by, the squeeze (24; squeeze) that are coupled to bed 23 to be movable from side to side along the bed (23) a, by moving the bed 23 to the upper squeeze by drawing a portion of the contact pieces (20, 24) and squeezing (24) to the squeeze (24) in a state comes in contact with the specimen moves along the bed 23 is pulled out to the specimen (20) in sequence, the sample surface was eliminated in the inclusions is characterized in that so that the surface defects formed in that portion.
