刚性离合器在开式曲柄压机中应用得非常广泛,一般都是通过足踏或电磁铁来操纵它的脱开和接合。由于目前使用的MQI系列拉式牵引电磁铁的允许操作频率很低,额定牵引力在5～25公斤的几种电磁铁,其允许操作频率为每小时200次,而开式曲柄压机的行程次数都比较高,如目前生产的J23—80每分钟行程次数为45次,假如行程次数的利用率为0.5,则电磁铁每分钟操作频率为22.5次,每小时达1350次,是允许操作频率的六倍多,因此在使用中,电磁铁经常损坏,影响生产;为了解决这个问题,不少使用厂是把电磁铁拆掉,改装成足踏操纵,但是由于踏下
Rigid clutches are widely used in open crank presses and are typically operated by pedals or electromagnets to disengage and engage them. Due to the low operating frequency of the currently used MQI series pull traction electromagnets, several electromagnets with a rated traction of 5 to 25 kg allow an operating frequency of 200 times per hour, while the number of trips of an open crank press Are relatively high, such as the current production of J23-80 trips per minute for 45 times, if the utilization of the number of trips is 0.5, then the operating frequency of electromagnet per minute 22.5 times, up to 1350 times per hour, is to allow the operating frequency More than six times, so in use, electromagnets often damaged, affecting the production; In order to solve this problem, many use the factory is the electromagnet removed, converted into foot control, but due to tread
