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(qū)動系統(tǒng)、傳動系統(tǒng)、控制顯示等系統(tǒng)組成，適用于各 種螺旋彈簧的疲勞性能試驗。該拉力機由電磁調(diào)速系統(tǒng)控制電機運行，通過偏心裝置帶動連桿使 壓板往復(fù)上升、下降，完成對彈簧的往復(fù)壓縮疲勞拉力試驗。該機無污染、效率高，具有較寬的調(diào)頻 范圍和試驗空間，配上合適的輔具，可完成不同規(guī)格的彈簧疲勞試驗。該拉力機通過單片機控制，實現(xiàn)試驗次數(shù)達到自動停機功能，該機集成度高，結(jié)構(gòu)簡單，故障率低，性能穩(wěn)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.
