操作規程: 本試驗機在無震動的環境中直接放在平臺上使用，平臺必須校正水平（1/A0）。 作抗力5000N范圍內的試驗時（使用雙杠桿）將抗折夾具掛在小杠桿的中間刀刃上（即如圖一所示），如作抗力A0N范圍內的試驗時（使用單杠桿）則必須卸下小杠桿及原聯結于大杠桿（8）的短拉桿(9)和力承座(7)并將夾具上部借長拉桿（8）聯結于大杠桿上，下半部則從原位旋出擰入與上半部相對位置的底座(27)上的螺母(2)中。 試驗前,**先接通電源,按下游動砝碼上的按鈕(21)，用手推動游動砝碼左移，使游動砝碼上游標(19)的零線對準標尺(26)的零線，放開按鈕后對準的刻線可能會有所移動，此時可用手在絲桿右端的滾花部分轉動絲桿，移動游動砝碼,使兩根零線重合。調整處于揚角指示板后邊位置的置零觸頭螺絲（31），使之剛與游動砝碼接觸，然后再用螺母（32）鎖緊置零觸頭螺絲(31)校對游標(19)與標尺的零線是否重合,如A重合,應重新調節置零觸頭螺絲,重復上述調整直至游動砝碼與置零觸頭螺絲剛好接觸時游標與標尺的零線重合為止。 松開鎖緊螺母（14）及（16），移動大、小平衡B，使大杠桿（17）盡量處于平衡，然后擰動鎖緊螺釘，將大平衡B（15）鎖緊于大杠桿上，移動小平衡B（12）上的螺帽（13），使小平衡B移動，直至大杠桿平衡為止，然后用鎖緊螺釘，將小平衡B鎖緊于大杠桿上，注意大小平衡B的鎖緊必須可靠，以免在使用過程中由于試件斷裂，大杠桿下落時受震動而破壞了調好的平衡。將試體放入抗折夾具內,以夾具上的對準板(5)由手感及目測對準，轉動夾具下面的手輪（1），使下拉架（3）上的加荷軸（4）與試體接觸，并繼續轉動一定角度，使大杠桿有一定揚角，數據根據試體斷裂時的變形量決定，原則是試體斷裂時應使大杠桿盡量處于水平位置，揚角的數值可在揚角指示板上讀出。（每格為2°）按電氣控制箱(28)上的起動按鈕,，電動機（10）立即轉動絲桿推動游動砝碼右移，機器開始加荷，大杠桿逐漸下沉，在大杠桿接近水平時，試體斷裂，處于大杠桿右面端頭的限位開關撞板(29)推動限位開關,斷開電動機電源,電動機立即停轉，此時便可以從游標的刻線與標尺讀出試體抗力或抗折強度值,至此一次試驗結束。 按下按鈕（21），即可推動游動砝碼左移，游動砝碼復位，接著可做**次試驗。 機器在使用過程中必須保持清潔、干燥，特別是各刀刃及刀刃承要防止生銹，以免降低靈敏度與正確度。刀刃及刀刃承間A得有任何潤滑油，以免粘住灰塵，阻滯杠桿運動，影響靈敏度，使用完畢應將機器罩上防塵罩。 大杠桿右端限位開關撞板必須調整到大杠桿下落到底時限位開關剛剛動作，切忌調整在過早使限位開關動作的位置，以免撞壞限位開關。加載用的游動砝碼在杠桿上，未按下按鈕時A應有過大的左右竄動，使用久時，游動砝碼在絲桿上有明顯顫動現象時，可更換半螺母，若需要請即來廠購置。 當游動砝碼有竄動時，可按如下方法解決： 只要在絲桿頭右端的軸承蓋上墊些青殼紙即可。 Third, the operating rules of the cement electric bending tester: This test machine is used directly on the platform in a vibration-free environment. The platform must be calibrated to a level (1 / A0). When testing in the range of resistance 5000N (using double levers), hang the anti-folding fixture on the middle blade of the small lever (that is, as n in Figure 1). Remove the small lever and the short lever (9) and the force bearing seat (7) originally connected to the large lever (8) and connect the upper part of the fixture with the long lever (8) to the large lever, and the lower half is rotated from the original position Screw out into the nut (2) on the base (27) opposite to the upper half. Before the test, ** first turn on the power, press the button (21) on the downstream moving weight, and push the swimming weight to the left by hand, so that the zero line of the upstream weight (19) of the swimming weight is aligned with the ruler (26 ) Zero line, the engraved line aligned after the button is released may move. At this time, you can turn the screw with the knurled part on the right end of the screw and move the weight to make the two zero lines coincide. Adjust the zero-setting contact screw (31) behind the angle indicator plate so that it just comes into contact with the swimming weight, and then use the nut (32) to tighten the zero-setting contact screw (31) to adjust the vernier (19). Whether it coincides with the zero line of the ruler. If A coincides, the zero-setting contact screw should be readjusted and the above adjustment is repeated until the vernier and the zero line of the ruler coincide when the moving weight and the zero-setting contact screw just touch. Loosen the lock nuts (14) and (16), move the large and small balance B so that the large lever (17) is as balanced as possible, and then turn the locking screw to lock the large balance B (15) on the large lever , Move the nut (13) on the small balance B (12), make the small balance B move until the large lever is fully balanced, and then use the locking screw to lock the small balance B on the large lever, pay attention to the size balance B The locking must be reliable, so as not to break the adjusted balance when the large lever is dropped due to the test piece breaking during the use process. Place the specimen in the anti-buckling fixture, and align it with the alignment plate (5) on the fixture by feel and visual inspection. Turn the handwheel (1) under the fixture to make the loading shaft (4) on the pull-down frame (3). ) Make contact with the specimen, and continue to rotate a certain angle, so that the large lever has a certain elevation angle. The data is determined based on the amount of deformation when the specimen breaks. Can be read on the angle indicator. (2 ° for each division) Press the start button on the electric control box (28), the motor (10) immediately rotates the screw to push the weight to the right, the machine starts to load, the large lever gradually sinks, and the large lever When the level is close to the level, the specimen breaks. The limit switch bumper (29) at the right end of the large lever pushes the limit switch, disconnects the motor power, and the motor stops immediately. At this time, you can read from the marker line and scale of the cursor The test body resistance or flexural strength value is obtained, and one test is ended at this time. Press the button (21) to move the swimming weight to the left, reset the swimming weight, and then perform ** tests. The machine must be kept clean and dry during use. In particular, each blade and blade holder must be rust-proof to avoid reducing sensitivity and accuracy. There must be any lubricating oil in the blade and the blade holder A to avoid sticking dust, blocking the movement of the lever, and affecting the sensitivity. The machine should be covered with a dust cover after use. The limit switch striker on the right end of the large lever must be adjusted to the limit switch just when the large lever drops to the end. Do not adjust the position where the limit switch is activated too early to avoid damaging the limit switch. The moving weight for loading is on the lever. When the button is not pressed, there should be excessive left and right movement of A. If the swimming weight has obvious vibration on the screw rod for a long time, you can replace the half nut. Need to come to the factory to purchase. When the swimming weight moves, it can be solved as follows: Just put some green paper on the bearing cover at the right end of the screw head.
