Strippers
There are tow types of strippers: fixed or spring-operated.The primary function of either type is to strip the workpiece from a cutting or noncutting punch or die.A stripper that forces a part out of a die may also be called a knockout, an inside stripper, or an ejector . Besides its primary function, a stripper may alwo hold down or clamp, posirion ,or guide the sheet, strip , or workpiece.
剥离器（脱模机）
有两种类型的剥离器: 固定的和弹簧驱动的．对于这两种类型而言,它们的主要功能都是将工件从剪切或者非剪切冲头（冲栽模）上剥离．促使冲栽模的一部分与其自身分离的剥离器亦叫做脱模装置,内置剥离器或者脱模器（推出器）．此外,剥离器还起着固定装置,薄板,剥片和工件的作用．
The stripper is usually the same width and length as the die block ,In simpler dies, the stripper may be fastened with the same screws and dowels that fasten the die block ,and the screwheadw will be counterbored into the stripper ,In more compex tools and with sectional die blocks, the die block screws will usually be inverted , and the stripper fastener will be independent .
剥离器通常与冲栽模块等长等宽．在一些构造更为简单的冲栽模中,剥离器也许会和模块共用同样的螺丝和暗榫固定,同时螺丝钉的头部将钻埋于剥离器内．对于一些较为复杂的工具和那些组合式冲栽模而言,螺丝钉通常都是倒置的,而且剥离器的扣件都是独立的．
The stripper thickness must be sufficient to withstand the force required to strip the strip the stock from the punch , plus whatever is required for the stock strip channel. Except for very heavy tools or large blank areas, thethickness required for screwhead counterbores ,in the range of 3/8” to 5/8”(9.5mm—16mm),will be sufficient.
剥离器要有足够的壁宽以经受将坯料从冲压机上剥离所需要的压力以及任何冲模通道所需的力． 除非是重量级的工具或者有相当大的接头部分,通常对于螺丝头的平孔钻的宽厚度应该达到9．5MM至16MM．
The height of the stock strip channel should be at least 1.5 times the stock thickness . This height should be increased if the stock is to be lifted over a fixed pin stop .The Channel widthshould be the width of the stock strip, plus adequate clearance to allow for variations in the width of the strip cut.
坯料剥离通道的高度应当至少是坯料厚度的1．5倍．如果坯料的高度被提升至超过了固定的挡料销（定位销）,这个高度就应当相应地增加．通道的宽度应当与坯料条的宽度相等,同时要留出足够的边隙以应对不同宽度的剪切样条．
Choice of the methods of applying springs to stripper plates depends on the required pressure, space limitations, shape of the die, nature of the work ,and production requirements . Figure 9-12 presents a number of such methods.
如果要将弹簧应用到分馏柱塔板上,那么你必须考虑其所需的压力,空间的尺度限制,模具的形状,工件的性质与质地以及生产规格的要求．（这些因素都将影响弹簧的选择与应用方式）
图9－12展示了一些相应的应用方式．
