The die supplier will provide chutes to prevent the possible build-up of
parts and/or scrap under the die. Scrap length should not exceed the
pitch of die. In situations where the size of scrap or the overall length
of scrap prevents the easy removal from the die,the scrap will be cut
into smaller pieces that will aid in their removal.
任何地方，废料都能够自动的从模具中移出，模具供应商应提供斜道阻止废料在模具内的可能的堆积，废料长度不能超过模具的步距。
在因
废料尺寸或权长阻止其从模具中移出的地方，废料都应该切成小段辅助
其移出。
4．Tooling Engineer will specify additional requirements, such as
containers or conveyors, supplied with the die.
模具经理将指明一些附属要求，臂如供应集装箱或搬运器。
G. Die sets:
1. See section VI for “Stamping and marking” of die set.
模座压印与雕刻看章节VI
2. Die sets will include: 模座应包括：
a. Guide pins/bushings that are the precision ball bearing type
(Lempco, Danly, etc.).
导柱/导套应该是精密滚珠类（Lempco, Danly, etc.）
b. Guide pins will be staggered, to prevent the incorrect assembly
of the die set.
导柱应该防呆，防止模座错误的安装。
c. Diameter of guide pins must be a minimum of 75% of shoe
thickness.
导柱直径必须是模座厚度的75%。
d. Guide pin ends must have .250” clearance when die is fully
closed.
当模具闭合时导柱末端到模座上表面必须有.250”的间隙。
e. 4 post die sets are to be used unless otherwise specified.
除非其它说明，应使用四导柱的模座。
3. Provide thrust blocks per Tool Engineer’s write up. 根据模具经理的书面要求提供靠刀块。
4. Heel block wear plates should be tool steel on the bottom shoe and
permanent graphite impregnated solid bronze material on the top shoe.
IEM is Su-dan’s preferred supplier.
在下模的靠刀耐磨板使用模具钢，在上模的使用带石墨自润滑的
青铜耐磨板。
5. Minimum shoe thickness will be 2” on light duty dies, 3” on medium
duty applications (up to 40”), and 4” on h eavy duty applications (up
to 108”).
在轻载荷的模座厚度为2”，中等载荷的模座厚度为3”（长度到
40”），重载荷的模座厚度为4”（长度到108”）。
H. Die mounting requirements: 模具安装要求：
1. Provisions for die mounting will be specified at the preliminary
design review.
在初级设计中应详细说明提供的模具安装说明。
2. Top and bottom shoes or parallels will be provided with 2” clamping
height surface and 1” slots for bolts.
上下垫脚应有2”高的装夹面以及1”的螺丝固定槽。
3. Progressive dies will include a provision for aligning the centerline
of the die with centerline of the press, this required keyway slot size is
1.020” wide and 1” deep.
连续模应提供键槽（1.020” 宽1”深）使模具与冲床对中。
4. Multiple secondary operation dies to be mounted on a common
plate to run in one press whenever possible. (To be determined at
pre-engineering launch meeting).
只要可能，复合二重工序模具安装在一个公用的模板上，在同一台冲床中进行冲压。
I. Maintenance requirements: 维修要求：
1. Die sections will be mounted with screws through the die section
into the shoe in a manner that will permit section removal while the die is in the press.
模具入子应用螺丝固定在模座上，这将有助于在冲床上对入子进行维修。
a.All die sections will be provided with “Jack Screw Holes” a method
for removal from the dowels. If jack screws cannot be used than
angled slots need to be installed for pry bar access.
所有的模具入子都提供起吊螺丝孔方便从合销上移除。
如果不能使用
起吊螺丝孔，应在入子上作撬模杆进入的斜槽。
2. Whenever feasible cutting steels which carry a form radius will be
designed to be sharpened without redressing the form radius. Inserts
should be used whenever possible.
所有的连剪带折冲设计时应考虑：当模尖刀口时不会影响成形圆角。
只要可能都应使用入子
3. For maximum support use nest blade punches. 最大可能使用镶嵌刃口的冲子。
a. Entire assembly will be designed to be shimmed at sharpening.
整体结构在磨尖刀口时可以用垫片垫。
b. Tap into blade for mounting.。
