V.  Pressure pins: 
1.  AISI 1045 air pins with flame hardened chamfered ends will be furnished by the supplier.
2.  Unless otherwise specified, the six inch J.I.C. pattern will be followed for the drilling of pressure pin holes in the shoe of all draw dies.
3.  The length of air pins will be determined as follows:
    a.  The length and diameter of the air pins below top surface of the bolster will be furnished by the Project Manager.
4.  The length of the air pins above the top surface of the bolster will be legibly stamped on the die shoe in the following manner:  Length of air pins above bolster “___________” (put in  dimension in inches).
5.  The pins will be stamped with the die number and total length of  the pin.
W.  Forming and drawing dies:  成型及拉伸模具
1.  Unless otherwise specified by the Project Manager, all draw dies will have nitrogen systems.
      除非项目经理其它指定，所有的拉伸模具必须为氮气弹簧系统。
2.  All flange and form steels are to be made shimmable and heeled whenever possible.  In severe forms the sections should be coated per Su-dan specified coating.
      只要可能所有翻边及成型部件应设计成可垫式的并有靠刀。在受力很大的成型中，入子必须做Su-dan指定的镀层处理。
3.  The base of all form punches or sections is to be at least one times the height.
    所有成型冲及入子的底部至少为其高度的**倍。
4.  All cutting sections are to be separate from any form steel.  This is to eliminate the problem of regrinding forms when sharping and shimming steels.
    所有的切断入子应从折弯冲中分离出来，从而保证当磨尖刀口时不需要再研磨圆角。
5.  Back relieve form sections for over bend development.
6.  Draw beads will be inserted.  拉伸压条采用镶嵌形式。
7.  Vent holes will be provided to avoid “air locks” in the die. 在模具中应提供排气孔防止“空气锁”。
8.  Blank holding rings, pressure pads, etc. will be confined to prevent accidental removal, and guarded to prevent foreign objects from getting under them.
      下料固定环，压力垫等必须加以限制防止偶尔的松动，并防止外界的物体进入里面。
9.  Pads which bottom out, should not have spring pockets.          *底的垫板，不需要弹簧保护装置。
10. Pads that bottom out will have hardened plates.          *底的垫板应该热处理。
11. Form dies should coin on radius.        成型模具应该倒圆角。 
X.  Cam and slide type dies:          凸轮及滑块模具
1.Where appropriate, standard cams should be used most of the time.  Cam surface will be inserted with self lubricated wearplates/strips.  No oil grooves are acceptable unless approved by Tooling Engineer.  IEM is the preferred supplier to Su-dan.
    在适当的地方，尽量用标准的凸轮机构。凸轮表面应有自润滑耐磨板，除非得到模具工程师的同意油槽是不允许的。IEM是Su-dan的****。
2.Cams will be rigidly guided and supported throughout their entire operation cycle.
      在凸轮完全行程中必须被坚硬的导向及支撑。
3. All cam slides to be adjustable in the press either by an insert on the cam slide or on the driver.
      在冲床中可通过在凸轮或驱动装置上的镶件调节凸轮滑块。
4.    Positive return cams as directed by Tool Engineer. 正面返回的凸轮应遵循模具工程师的意见。
5.    Provide positive stripping.              提供正面脱料。
