一、工作原理(见图1)在设计通用辊式送料装置时,考虑能使冲压与送料功作协调,充分利用冲床的动力,在冲床曲轴一端装一个偏心座,通过曲柄连杆机构驱动离合器把动力传给主动送料辊轴8,并通过齿轮传动带动被动送料辊7同时转动。因原料为条状,故在模具前面设有一对拉料辊,经链轮传递使两对辊轴同步作间歇转动,依靠送料辊转动摩擦把料送入模腔。在被动送料
First, the working principle (see Figure 1) In the design of a common roll feed device, consider making stamping and feeding work for coordination, make full use of the power of the punch, the end of the press crankshaft equipped with an eccentric seat through the crank rod drive clutch The power is transmitted to the active feeding roller shaft 8 and drives the passive feeding roller 7 to rotate at the same time through the gear transmission. Because the raw material is strip, so in front of the mold is provided with a pair of pull the material roller, the transmission through the sprocket so that the two pairs of rollers synchronous intermittent rotation, rely on the feed roller rotating friction material into the mold cavity. In the passive feeding
