 Product overview:

SDL series testing machine main types of SDL-300, SDL-500, SDL-300W, SDL-500W horizontal steel strand relaxation test machine is mainly used for steel strand relaxation testing, detection of steel stranded wire and other metal wire rod uniaxial tensile relaxation strength characteristics. Can be widely used in quality inspection departments, construction units, steel hinge line and steel production enterprises, is a new type of modern construction mechanical test equipment.

Main functional features:

The main machine is four column or double column rigid frame, there are two types of vertical and horizontal type, the lead screw to adjust the pull head moving, load speed stepless setting.

Servo motor and driver, combined with high precision sensor, high precision, wide range, multi function servo control system is realized by using the full digital closed-loop servo control of the Panasonic servo motor.

Direct measurement of specimen deformation distance, eliminate the influence of chuck slippage, high test precision.

SDL-300 horizontal steel strand relaxation testing machine full use of computer technology to test the parameters of the various parameters of the preset, automatic measurement, control, data processing, drawing a variety of curves and print reports, etc.. The relaxation rate of 1000 hours can be automatically extrapolated by the test software.

 new structure of tensile test machine screw type clamp

SDL-300/500 horizontal steel strand relaxation testing machine is the traditional clamp block in the clip plane tooth block or insert a V type tooth, clamping bar clamping plate. The clamping block when working with sample contact area is basically the same or little change. When the clamping part of the tooth is damaged, the tensile test will skid, holding live specimens, the clamp block scrap.

Is to replace the original common clamp with two rotating screw. Turning the screw can make the non clamping area into a holding area. Let all the teeth have the opportunity to participate in the work. It can not only clamp round the sample, but also can clamp the specimen. Due to the screw and the specimen was tangent arc, cut into small resistance, high reliability of the clamping, basically put an end to the slippage phenomenon of a tensile stage.

Screw clamp block bearing capacity, regardless of contact stress, or the compressive strength, flexural performance and bearing capacity of ordinary straight blade tooth is.

The SDL-300/500 horizontal tensile testing machine has the advantages of simple structure, convenient processing, easy to control tooth geometric accuracy, high concentricity, long service life. As the screw position can be used at least 6, so its life expectancy is increased by 6 times, and save time and materials, so that each side to reduce the cost of 70%.
