西德奥姆柯(EUMUCO)公司生产的双点热模锻压力机,具有双偏心、双连杆和两个滑动轴承。双偏心和双连杆的宽度等于滑块的宽度,因此压力沿着一条直线由偏心轴通过连杆和球头座传到滑块上。这样,和一般的单点热模锻压力机相比,这种双点结构就能更好地承受偏心载荷。当采用自动传送装置进行多工位模锻(这时终锻工序往往不在滑块的中心位置上)时,这一点就显得格外重要。楔式传动热模锻压力机(图1)就是
Double-point hot forging presses from EUMUCO with double eccentricity, double connecting rod and two plain bearings. Double eccentricity and double link width equal to the width of the slider, so the pressure along a straight line from the eccentric shaft through the connecting rod and ball seat to the slider. In this way, the two-point construction is better able to withstand eccentric loads than conventional single-point hot forging presses. This is especially important when automatic transfer is used for multi-station swaging, where the final forging process is often not at the center of the slide. The wedge drive hot forging press (Figure 1) is
