[0002] When steel companies produce steel, they usually need to test the physical properties of the products, including tensile and impact performance tests. Before the performance test, it is necessary to sample the steel blanks at fixed positions in advance according to the requirements of GB / T 2975 for tensile, impact and other performance tests. To this end, the sample maker calculates the sampling position values ​​of the tensile and impact samples (such as 1 / 3 or 1 / 4 width) or looks up the table according to the different specifications of the steel models, first draws the position to be cut on the blank, and then uses the cutting tool to prepare the sample for tensile and impact testing. Since the steel needs to be tested for tensile and impact performance, and a large number of samples need to be tested every day during production, the operator needs to spend a lot of time using a steel ruler to mark the blank, and the position cannot be fixed, which often causes inaccurate material cutting.

[0003] In view of the above factors, a positioning ruler for cutting steel sample blanks is specially designed. The positioning ruler for cutting steel sample blanks is used for sampling and positioning, which not only improves the accuracy of material cutting, but also improves the sawing efficiency for batches of steel blanks, making it convenient for on-site operators to use.
