1. Equipment model and specifications JWJ-3 Electric Metal Sheet Reverse Bending Testing Machine 2. Equipment use This testing machine is mainly used for the repeated bending test of the metal sheet to test the performance of the metal sheet to withstand plastic deformation and the defects displayed during repeated bending; Meet the test standard GB/T 238-2013 "Metallic materials-wire-reverse bend test"; GB/T 235-2013 "Metallic materials-Sheet and strip-reverse bend test" This machine is widely used in steel, construction industry, stainless steel sheet, silicon steel sheet and other production and use manufacturers; By expanding with special fixtures, bending tests of other specifications of metal wires can also be performed; 3. Main technical parameters Sheet sample thickness - 0.3mm to 3mm Sheet sample length - ≥150 mm Reverse bending angle - ±90°±1° (plane bending) Counting range - 1 to 99999 Display mode - Digital display Counting method - Automatic recording of bending times Bending frequency - ≤60 times/min Motor power - 1.5kW Power supply - Three-phase, 380V, 50Hz Dimensions - 600×350×670mm Host weight - about 230 kg 4. Structural characteristics The testing machine is mainly composed of two parts: the host mechanical system and the electrical measurement and control system. It is driven by a two-stage reducer, and the test torque is applied to reverse bend the sample. The photoelectric switch is used to detect the number of bending tests. After the sample is broken, it will automatically stop, the pendulum rod will be reset, the digital display instrument will automatically display, and the number of bending times of the sample will be automatically recorded.
