Bending testing machine HL-BP300

fatigueautomaticPLC-controlled

1.Application This kind of machine is suitable to test the fatigue strength of metals or other materials. It is designed and manufactured fully according to the current standard GB4337-2015“method for rotary bending fatigue tests of metallic materials” and Standard ZBN71006-87 “Technical conditions of pure bending fatigue testers”. The testing machine is usually used to test the bending fatigue limitδ-1 of metals under the action of symmetrical repeatedly alternating bending force. It is used for the cantilever pure bending fatigue test of ferrous metal and its alloy materials under small temperature and high temperature conditions to determine the fatigue performance of metal circular cross-section specimens subjected to bending moment under rotating condition. The cantilever beam structure is composed of a frame, an AC high-speed motor and a driver, a measurement and control system, a loading weight, a controller, a lubricating device, a protection device, and the like, and a rotation counter is provided on the device. 2.Features -Horizontal structure, rotating speed stepless adjustable; -Automatic counting, automatically stop after reaching the specified number or breaking; -Radial force (or bending force) free adjustment; 3.Specification -Rotating speed: 2500rpm (Customizable as customer’s request) -Cantilever length:：150mm -Standard specimen holder collect dia: 8-10 mm -Dia at neck: 4 to 5 mm
