在弯板机上(如W67-80型)加工门、壁、盖等大型薄板零件的起伏图形,具有如下优点: (1)提高了零件的刚度和使其外形更美观; (2)可降低原材料的消耗和零件的重量; (3)操作方便、噪声较小。以图1所示零件的起伏图形在一般同吨位冲床上很难实现,而在弯板机上就很容易解决.原设计用2mmA3钢板现改为1.5mm A3钢板,降低了原材料消耗和零件的重量,而且成形后零件中心的强度和则度也比原来提高。应该注意的是:模具的结构应采用拼块式,因为这样可获得多种不同尺
In the bending machine (such as W67-80 type) processing doors, walls, covers and other large thin-plate parts of the ups and downs graphics, has the following advantages: (1) to increase the rigidity of the parts and make it more beautiful appearance; (2) can reduce the raw materials The consumption and the weight of parts; (3) easy to operate, less noise. Figure 1 shows the undulation of parts in the same general tonnage punch is very difficult to achieve, and in the bending machine is very easy to solve the original design of 2mmA3 steel is changed to 1.5mm A3 steel, reducing the consumption of raw materials and parts weight , But also after forming the strength and degree of parts center than the original increase. It should be noted that: the structure of the mold should be modular, because this can be a variety of different ruler
