彈簧疲勞拉力機的特點及用途
Features and use spring fatigue tensile machine
機械式彈簧疲勞拉力機是由驅動係統、傳動係統、控製顯示等係統組成,適用於各 種螺旋彈簧的疲勞性能試驗。該拉力機由電磁調速係統控製電機運行,通過偏心裝置帶動連杆使 壓板往複上升、下降,完成對彈簧的往複壓縮疲勞拉力試驗。該機無汙染、效率高,具有較寬的調頻 範圍和試驗空間,配上合適的輔具,可完成不同規格的彈簧疲勞試驗。該拉力機通過單片機控製,實現試驗次數達到自動停機功能,該機集成度高,結構簡單,故障率低,性能穩定、可靠,操作 簡單。
Mechanical spring fatigue tensile machine is composed of a driving system, transmission system, control and display system, fatigue test is suitable for each kind of spiral spring. Thetensile machine by electromagnetic speed control motor, the eccentric device drives the connecting rod to the press, complete reciprocating reciprocating up down, on the compression of the spring fatigue tensile test. This machine has no pollution, high efficiency,wide frequency range and test space, with appropriate assistive devices, spring fatigue testcan be done in different specifications. The tensile testing machine controlled by single chip,realize the test times reach the auto stop function, the machine has the advantages of simple structure, high integration degree, low failure rate, stable and reliable performance, simple operation.
