设计的冲压件必须形状简单,结构合理,以有利于简化模具结构、简化工序数量,即用少、简单的冲压工序完成整个零件的加工,减少再用其他方法加工,并有利于冲压操作,鱼尾板价格,便于***实现机械化与自动化生产,以高劳动生产率。
设计的冲压件,在保证能正常使用情况下,尽量使尺寸精度等级及表面粗糙度等级要求低一些,并有利于产品的互换,减少废品、保证产品质量稳定。
设计的冲压件,应有利于尽可能使用现有设备、工艺装备以及工艺流程对其进行加工,并有利于冲模使用寿命的延长。
压住材料。克服传统的模具设计结构,在卸料板上开出容料间隙(即模具闭合时,卸料板与凹模贴合,而容纳材料处卸料板与凹模的间隙为材料厚t-0.03~0.05mm)。如此,冲压中卸料板运动平稳,而材料又可被压紧。关键成形部位,卸料板一定做成镶块式结构,以方便解决长时间冲压所导致卸料板压料部位产生的磨(压)损,鱼尾板规格,而无法压紧材料。
Press the material. In order to overcome the traditional mold design structure, the clearance of material is opened on the discharge plate (i.e., when the die is closed, the discharge plate and the die are fitted,鱼尾板, and the gap between the discharge plate and the die is t-0.03 to 0.05mm). In this way, the discharging plate moves ***oothly, and the material can be pressed tightly. In the key forming part, the discharge plate must be made into an inlaid structure to facilitate the solution of the grinding (pressure) loss caused by the pressing part of the unloading plate for a long time, and the material can not be pressed.
清除冲压机床滑块底面、工作台面(或垫板平面)以及模具的上、下模座平面内的任何杂物或***。手工扳动冲压机床飞轮(或操纵点动按钮),调整上滑块到上死点位置,并转动调节螺杆,将连杆长度调到短(即闭合高度大)。
Remove any material or foreign object on the bottom of the stamping machine slide,鱼尾板生产, working table (or pad plane), and the upper and lower die base of the mold. Manually pull the stamping machine flywheel (or point moving button), adjust the upper slider to the upper dead point, and rotate the adjusting screw, the length of the connecting rod to the shortest (i. e. the maximum height of the closed height).
