[0016] Implementation case: installation of plate-shaped tensile specimens for constant load tension

[0017] 1. Select the appropriate upper chuck 17 and lower chuck 18 according to the size of the sample;

[0018] 2. Use figure 2 The upper chuck connecting groove 16 and the lower chuck connecting groove 17 in the upper chuck are respectively fixed in the groove through threads; wherein, the upper chuck connecting groove is connected with the adjusting screw through threads, and the lower chuck connecting groove 19 is passed through The pin is connected with the chuck fixing base 20, so that the chuck can be replaced through the chuck connecting groove;

[0019] 3. Lower the anti-drop support plate 7 in the anti-drop bracket 8 to the lowest point;

[0020] 4. According to the length of the sample, adjust the screw rod 14 so that the total length of the installation part is less than the height of the column, so as to ensure that the tensile stress is applied to the sample,...

Abstract

The invention relates to a dead load tensile device for a tensile test, belongs to the technical field of the tensile test of a metal material. The device comprises a frame part and a bearing part, wherein the frame consists of a frame base, a stud and an anti-falling bracket, with the stud and the anti-falling bracket being fixed to the frame base and the stud being used for assembling the bearing part; the bearing part is connected with the stud via a rolling bearing, the balance of a bearing capacity arm is realized through a balance regulator and a level instrument on the top of the bearing capacity arm, a sample is assembled between the head of the bearing capacity arm and a chuck fixing base in an adjustably connecting way and is axially tensioned in a manner of weight loading in order to realize manual loading and the constancy of the loading. In combination with the advantages of traditional equipment, the experimental device overcomes own shortages, can realize manual loadingand batch test, and can guarantee the constancy of the loading.

Description

technical field [0001] The invention belongs to the technical field of tensile testing of metal materials, and in particular provides a constant load tensile testing device capable of realizing batch tests and being easy to operate. technical background [0002] The constant load tensile test is an essential experimental program for testing the tensile mechanical properties and corrosion resistance of materials under tensile stress conditions. Usually, the constant load tensile test can only be carried out with the help of large-scale special test equipment. Therefore, the constant load tensile test equipment has always been the key to the test. At present, the traditional constant load loading equipment is mainly computer-controlled material tensile testing machine (or universal testing machine) and force measuring ring. Traditional loading equipment can exert a variety of mechanical properties on test samples, but this type of constant load loading equipment has its own s...
