Background
The manufacturing of rectangular springs requires trapezoidal steel wires, the cross section of each trapezoidal steel wire is nearly trapezoidal (as shown in fig. 1), namely, the two side faces of each trapezoidal steel wire have included angles, and the scale distance of the special-shaped steel wires is difficult to rapidly and accurately depict through the existing scale distance device. As mentioned in GBT228.1-2010 metallic material tensile test section 1, the elongation after break a is calculated in the following manner: a = (Lu-Lo)/Lo × 100%, wherein Lo is an original gauge length, Lu is a post-fracture gauge length, and the post-fracture elongation Lu-Lo should be measured to be +/-0.25 mm by using a measuring tool or measuring device with sufficient resolution. Therefore, accurate marking of the gauge length of the tensile sample is required necessarily to obtain accurate elongation after fracture. Meanwhile, when the special-shaped wire rod tensile test is carried out, the length of the tensile sample is not specially required (50 mm-100 mm all can), the length of the tensile sample is cut without increasing workload, and the fracture is ensured to be in the middle of the gauge length as far as possible, so that the corresponding gauge length engraving device needs to have certain universality and can be suitable for steel wire samples with different lengths.
