Background
The tensile measurement of the cable insulation sleeve is mainly used for evaluating the mechanical properties of products, and can show the capability of bearing external tensile force and deformation characteristics.
The national recommended standard general test method 11 section of cable and optical cable insulation and sheath materials general test method thickness and external dimension measurement mechanical performance test (GB/T2951.11-2008) is used for treating dumbbell test pieces, wherein before a tensile test, two marking lines are marked on the center of each dumbbell test piece. The distance between the two test pieces is 20mm for the bell test piece and 10mm for the bell test piece. That is, mark lines are made on the dumbbell test piece before stretching, and the interval between the two mark lines is 20mm or 10mm.
Before the tensile measurement is carried out, two ends of the dumbbell test piece are required to be fixed on the clamping heads, but the clamping heads of the existing tensile measurement device are used for clamping and fixing the test piece, the size design is large, and more parts of the two ends of the test piece are located in the clamping heads. When the bell test piece is measured, after the two ends of the test piece are fixed, the condition that the distance between marking lines is less than 10mm possibly exists, so that the measurement is inaccurate.
For example, chinese patent document CN211292357U discloses a dual-mode plastic tension machine, which comprises a screw, a motor, a supporting frame, an upper beam, a lower beam, wherein the supporting frame is of a frame structure, two screws are symmetrically and fixedly arranged on the left side and the right side of the supporting frame, an upper supporting beam and a lower supporting beam are arranged between the two screws through an upper pair of sliding blocks and a lower pair of sliding blocks, a pair of stretching clamps are arranged between the top of the supporting frame and the upper supporting beam, a pair of bending clamps are arranged between the lower supporting beam and the bottom of the supporting frame, the tops of the two screws are respectively connected with a motor output shaft through a coupling, the two motor output shafts are connected with a driving motor, and the driving motor is arranged at the top of the supporting frame. The utility model avoids the time of replacing the clamp, reduces the investment cost and greatly improves the working efficiency.
According to the technical scheme of the patent document, when the test piece is clamped by using the upper clamping jaw and the lower clamping jaw through stretching measurement, the test piece is clamped vertically, the problem that the test piece falls off after stress to affect measurement exists when the test piece is clamped vertically, and when the test piece is clamped by combining with the drawing, the two ends of the test piece are still clamped by the upper clamping jaw and the lower clamping jaw, so that the tension machine is not suitable for stretching measurement of the bell piece.
