Abstract

본 발명은 자동차용 도금강판의 스탬핑 성형공정중 마찰불량에 의한 파단을 방지할 수 있는 강판의 마찰특성을 평가시 롤러에 밀착되지 고정된 작업대에 시편을 안착시킨 다음 적정압력으로 가압후 작업대를 인발시킴으로 시편의 두께에 구애받지 않으면서 마찰계수의 측정작업이 가능한 것이며, 도금강판의 표면마찰특성을 평가하기 위한 마찰계수 시험장치에 있어서, 작업대(11)상에 고정되는 시편(12)에 가압하는 시험공구(13)가 하단부에 탈착 가능하게 장착되고 상방에 설치된 유압실린더(14) 구동으로 상·하이동되는 상부슬라이더(15)와, 상기 작업대(11) 저면에 밀착되게 설치된 수개의 롤러(16) 하방에 설치되어 시편(12)에 가압되는 수직하중 측정용 센서(17)와, 상기 작업대(11) 일방에 설치되어 시편(12)을 가압후 작업대(11) 인발시 시험공구(13)에 작용하는 마찰하중 측정용 센서(18)와로 구성된 것이다.The present invention, when evaluating the friction characteristics of the steel plate that can prevent fracture due to friction failure during the stamping molding process of automotive automotive steel sheet seats the specimen on a fixed worktable not pressed against the roller and then presses the worktable to the appropriate pressure It is possible to measure the coefficient of friction regardless of the thickness of the specimen by applying a friction coefficient, and the friction coefficient test apparatus for evaluating the surface friction characteristics of the plated steel sheet, which is pressed against the specimen 12 fixed on the work table 11 The test tool 13 is detachably mounted at the lower end, and the upper slider 15 is moved up and down by driving the hydraulic cylinder 14 installed upward, and several rollers 16 are installed in close contact with the bottom surface of the work table 11. The vertical load measuring sensor 17 which is installed below and pressurized on the specimen 12, and installed on one side of the workbench 11, pressurizes the specimen 12 to the test tool 13 when drawing out the workbench 11; production Sensor 18 for measuring the friction force that is configured waro.
