图1所示为小链条加工模具。冲制前,铡刀3在拉簧与压板10的作用下处于进料位置。冲头下降,推动铡刀截断线材,这时冲头刚好压住料,防止跳出。冲头继续下降,与弯脚板、滚轮配合将工件压制成型,压制过程见图2。冲头回升时,脱件机构顶出工件(图3)。 Figure 1 shows a small chain processing mold. Before punching, the trowel 3 is in the feeding position under the action of the tension spring and the pressing plate 10. Punch down, push the trowel cut off the wire, then punch just hold down the material to prevent jumped out. Punch continue to decline, and the legs, rollers with the workpiece will be pressed into shape, the suppression process shown in Figure 2. When the punch picks up, the ejector mechanism ejects the workpiece (Figure 3).
