23-40型电开式双柱可倾压力机,在使用过程中出现当曲轴到达(?)死点时,离合器处于分离状态,随着大齿轮旋转一周,连接键在凸轮上敲击数次,并发生曲轴跳动现象。冲床采用脚或手控操作,电磁铁吸合,操纵器的凸轮反转一角度,放开离合器的接合键,接合键在回位弹簧的作用下,拖动工作键反转90°,工作键和制动键由连接板连接(如图1),在工作键反转90°的同时,制动键顺转90°,分别卡住曲轴柄和中套(见图2a)。由于中套与大齿轮键连接,此时电机将动力传给小齿轮,小齿轮又传给大齿轮,大齿轮带动中套和曲轴转动,曲转带动连杆和滑块作上下往运动,进行冲压。当离合器分离时(见图2b),离合器的分离键和制动键半圆弧全部进入曲轴的半圆槽内,此时电机将动力传给小齿轮,小齿轮又传给大齿轮,大齿轮带动中套绕曲轴转动,即大齿轮空转。
23-40 type electric double column tilting press, in the course of the process, when the crankshaft reaches (?) Dead point, the clutch is in the separated state, with the big gear rotates one week, the connecting key hits several times on the cam , And crankshaft beating phenomenon occurred. Punch or manual operation by hand, electromagnet pull, flip the cam angle of the manipulator, release the clutch engagement, the key in the role of the return spring, drag the work key to reverse 90 °, the work key And the brake key are connected by the connecting plate (as shown in FIG. 1). When the work key is reversed by 90 °, the brake key rotates clockwise by 90 °, and the crank shaft and the middle sleeve are respectively stuck (see FIG. 2a). As the sleeve and the large gear key connection, this time the motor power to the pinion, the pinion and passed to the gear, the gear drive in the sleeve and the crankshaft rotation, crank drive link and the slider up and down movement, carried out stamping. When the clutch is disengaged (see Figure 2b), the clutch’s separation key and the semi-circular arc of the brake key all enter the semi-circular groove of the crankshaft. At this time, the motor transmits the power to the pinion and the pinion to the large gear, Central around the crankshaft rotation, that is, idle gear.
