Tensile testing machine is widely used in many industries, footwear, how to use the tensile testing machine? Why is the electronic tensile testing machine so popular in the footwear industry, footwear, tensile testing machine which has the advantage? We come to analyze. Tensile testing machine is mainly to any of the components of the shoe soles, heels, shoe uppers with tensile strength test, the applicability is more and more extensive, specific can see our footwear testing instrument. Before the test, in the toe or heel department to help end the junction cut about 3 cm, with tensile testing machine fixture are respectively clamped uppers and soles for tensile testing, testing whole shoe or shoe parts to help end the combining fastness. Constant product production of high precision tensile machine, equipped with a recorder, stretching speed can be set. The measuring range is 2000N, the precision is 0.1N, and is equipped with the clamp type clamp and the tool knife. Test procedure for tensile testing machine 1, the upper and the lower clamp of the upper and the lower parts of the upper and the sole which are separated by the tool knife are respectively clamped on the upper and the lower clamp. Fixtures should be firmly clamped, not slip. 2, the tensile testing machine fixture separation speed is set to 150mm/min + 20mm/min, start tensile test. 3, if the material is torn, the tool knife will be torn material cut to the adhesive. Don't cut ankylose interface. 4, the record of the tension in the whole process of displacement curve. The test results show that the tensile strength of the tensile axis is marked on the tensile axis of the tensile force displacement curve, and a straight line which is parallel to the displacement axis is drawn. If the force displacement curves are in parallel above the line or in parallel to the bottom line, but within 5 mm up to parallel lines above (including parallel lines), each peak on the curve calculation (including the peaks and troughs of the average force, calculation delete line of equality under the trough; if the force displacement curve is continuous above 5mm in parallel below the line, curve calculation of parallel lines in the following part of the peak (including the peaks and valleys) average tension.
