目前,由于国内异型钢材的品种规格比较少,所以我们叉车厂常采用自制的热压成形槽钢经过切削加工来制作叉车门架。这些对我们提出了叉车门架槽钢高效加工的新课题。我厂生产的CPQ-0.5型叉车的外门架槽钢和内门架槽钢。包括工艺面在内,分别有五个和七个加工面,如图1和图2所示;加工面的长度分别为1438mm和1408mm。过去我们用龙门刨床加工,为了防止装夹零件变形,切削量不能大,因而功效很低,每班加工一根都
At present, due to the relatively small variety of domestic special-shaped steel, forklift trucks are often manufactured with self-made hot-formed channel steel through forklift trucks. These put forward to us a forklift door frame efficient processing of new topics. I plant the CPQ-0.5 forklift outside the door frame channel and the inner frame channel. Including the process side, respectively, there are five and seven processing surface, as shown in Figure 1 and Figure 2; processing surface length of 1438mm and 1408mm. In the past we use gantry planer processing, in order to prevent the clamping parts deformation, the amount of cutting can not be large, so the effect is very low, each class processing a
