Description
技术领域 technical field
本实用新型涉及模具领域，尤其是一种异型U形锁扣成型模上刀。 The utility model relates to the field of moulds, in particular to an upper knife of a special-shaped U-shaped lock forming mold.
背景技术 Background technique
模具在外力作用下使坯料成为有特定形状和尺寸的制件的工具。广泛用于冲裁、模锻、冷镦、挤压、粉末冶金件压制、压力铸造，以及工程塑料、橡胶、陶瓷等制品的压塑或注塑的成形加工中。模具具有特定的轮廓或内腔形状，应用具有刃口的轮廓形状可以使坯料按轮廓线形状发生分离(冲裁)。应用内腔形状可使坯料获得相应的立体形状。模具一般包括动模和定模(或凸模和凹模)两个部分，二者可分可合。分开时取出制件，合拢时使坯料注入模具型腔成形。模具是精密工具，形状复杂，承受坯料的胀力，对结构强度、刚度、表面硬度、表面粗糙度和加工精度都有较高要求，模具生产的发展水平是机械制造水平的重要标志之一。对常规的U形锁扣进行成型加工时的工艺为：切断弯曲——冷镦——旋铆。但是对一种异型U形锁扣，由于锁扣U形件两个支脚的长度不一致，在进行折弯时，对折弯成U形的半成品工件的两个支脚的长度要求符合生产要求，如果是把工件拿出折弯设备来进行测量验收，工序增加、操作繁琐。 The mold is a tool that makes the blank into a workpiece with a specific shape and size under the action of external force. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a precision tool with a complex shape and bears the bulging force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing. The process of forming the conventional U-shaped lock buckle is: cutting and bending-cold heading-spin riveting. However, for a special-shaped U-shaped lock, because the lengths of the two legs of the U-shaped part of the lock are inconsistent, when bending, the length requirements of the two legs of the semi-finished workpiece bent into a U-shape meet the production requirements. Take the workpiece out of the bending equipment for measurement and acceptance, which increases the process and cumbersome operation.
