Description
Technical Field
The utility model relates to a coating steel sheet surface auxiliary device that rules belongs to metallurgical industry coating steel sheet inspection auxiliary assembly technical field.
Background
When the notch corrosion resistance of the sample with the coating is detected, the surface of the sample is often subjected to scribing operations such as scribing and forking or linear scribing, and the like, so that the surface coating of the steel plate substrate is scratched, the sample substrate to be detected is leaked out, and then the notch corrosion resistance of the sample with the coating is detected by adopting a corrosion test.
At present, when operations such as cross scribing and straight scribing are performed on the surface of a coated steel plate, hands are often in direct contact with a to-be-measured sample, a ruler is fixed on the to-be-measured sample, cross scribing and scribing are performed, due to the fact that no professional scribing auxiliary device is arranged, the scribing method is low in efficiency, the hands are easy to hurt, particularly for samples with relatively hard coatings, such as a zinc layer, an aluminum layer or a zinc layer or an aluminum layer with electrophoretic paint, the depths of the coatings scribed during scribing operations of different samples are not uniform, the scribed shapes are different, if the force control is not good, the scribing depths of different positions of the samples are different, the experimental efficiency is affected, and the accuracy and the scientificity of a corrosion test result are seriously affected.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a coated steel plate surface marking off auxiliary device, can convenient and fast rip base member surface coating, spill the sample base member that awaits measuring, reduce sample surface marking off operation error, guarantee coated steel plate corrosion test result's accuracy and scientificity, solve the problem that exists among the background art.
The technical scheme of the utility model is that:
the utility model provides a coated steel sheet surface auxiliary device that rules, contains drawing board, fretwork and rules and sample, and the sample is rectangle coated steel sheet, the drawing board is "worker" style of calligraphy that makes up into a body structure by rectangular plate A, rectangular plate B and rectangular plate C, and rectangular plate B is located between rectangular plate A and the rectangular plate C, and the front of drawing board is the plane, be equipped with respectively on rectangular plate A and the rectangular plate C at the drawing board back with sample both ends assorted frame A and frame B, be equipped with the fretwork on the rectangular plate B and rule.
And a chamfer is arranged on the hollowed-out marking line on the rectangular plate B.
The hollow-out lineation on the rectangular plate B is two straight lines which are arranged in a crossed manner.
The hollow-out scribing lines on the rectangular plate B are straight lines.
Adopt the utility model discloses, during the use, at first fix the sample on the frame at the drawing board back, then openly utilize the blade to draw the line to the sample along the fretwork on the rectangular plate B through the drawing board, until drawing the coating steel sheet base member surface coating of brokenly, spill the sample base member.
The utility model has the advantages that: can convenient and fast scratch the base member surface coating, spill the sample base member that awaits measuring, reduce sample surface marking off operation error, guarantee accuracy and the scientificity of coating steel sheet corrosion test result, operating efficiency is high moreover, and the application of force is even, does not hinder the hand, does not harm the drawing board yet.

Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to the attached drawings 1-6, the auxiliary device for scribing the surface of the coated steel plate comprises a drawing board 1, a hollow scribing line 2 and a sample 3, wherein the sample 3 is a rectangular coated steel plate, the drawing board 1 is in an I shape of an integrated structure formed by combining a rectangular plate A1-1, a rectangular plate B1-2 and a rectangular plate C1-3, the rectangular plate B1-2 is located between the rectangular plate A1-1 and the rectangular plate C1-3, the front side of the drawing board 1 is a plane, a frame A1-4 and a frame B1-5 which are matched with two ends of the sample 3 are respectively arranged on the rectangular plate A1-1 and the rectangular plate C1-3 on the back side of the drawing board 1, and the hollow scribing line 2 is arranged on the rectangular plate B1-2.
In this embodiment, referring to fig. 1-6, the drawing board 1 is a teflon board, the surface friction coefficient of the teflon board is low, the teflon board is not adhered with a coating and is easy to clean, the accuracy and the scientificity of the corrosion test result are increased, the teflon board is in an i shape, the teflon board is convenient to take and place, the surface of the teflon board is required to be smooth and flat, and the size of the teflon board is 6 mm longer than the length and width of the sample.
The hollow-out position of the hollow-out marking-out 2 on the rectangular plate B1-2 adopts a fillet design, so that the drawing board is prevented from being damaged when the drawing tool is used for marking.
According to the standard of corrosion test, the hollow-out score lines 2 on the rectangular plate B1-2 can be cross lines as shown in fig. 1 and 2, can also be straight lines as shown in fig. 3, 4 and 5, and can also be in any other shapes.
The specific scribing process is as follows:
selecting a proper picture frame 1 according to the size of a sample and the required scribing shape of a corrosion standard, placing a sample 3 on a platform, then placing the back of the picture frame 1 on the sample 3, fixing the sample 3 through a frame on the back of the picture frame 1, and finally scribing the sample along the hollowed-out scribing line 2 by using a blade until the scribing coating leaks out of a matrix of the sample 3.
