上模

But sometimes I think if we can put all the centers together like dynamic balance and stripper pressure center of punch holder, vibrate and clamping center of die shoe etc, how perfect it is!

很多时候我在想，如果我能够将所有的中心例如上模的动平衡中心、卸料中心、下模的振动中心、夹钳固定中心等等都放在一条中心线上，那将是一个怎样的境界？

Through using second diffluence with protruding die, improving the metal flow equably and jointed sufficiently, the extrusion dies for these kinds of industrial aluminium profiles are designed possibly.

对上模采取二次分流的形式来改善金属均匀流动和充分焊合，从而合理地设计出这类型材的模具。

On the scale of punch and die with punching and bending die punch; Die positioning pulled positioning and bending Die top two pieces of equipment; 6 punch with epoxy fixed on the next model, since blanking punch and bending die role.

上模为凸凹模起冲裁凹模和弯曲凸模作用；模具中定位板起定位和弯曲凹模顶件装置两种作用；六个凸模用环氧树脂浇注固定在下模上，起冲裁凸模和弯曲凹模作用。

In order to make good use of the expert's experience and knowledge in the forging technology and die design process, object-oriented knowledge modeling methodology is proposed in this paper based on the character of hammer forging die design, and the knowledge model and knowledge database of the knowledge-based hammer forging design system is built .

将模具设计的经验和知识应用于锻造工艺与模具设计过程中，针对锤上模锻设计的特点，提出了面向对象的知识建模方法，建立锤上模锻设计支持系统的知识模型和系统的知识数据库。

The production process includes hammer die forging,pressure forging, roll forging forming,and precision rolling-die forging composite technology.

前轴是汽车中的大型重要锻件，其生产工艺可归纳为锤上模锻、热模锻压力机上模锻、成形辊锻、精辊-模锻复合工艺等几种类型。

The top die shoe must be drilled for positive knockout if required.

如有必要在上模座上钻孔方便正面取出。

When this situation becomes necessary, springs which have to extend through the top of the shoe are to covered by a plate, mounted to the die shoe to maintain spring pressure.

弹簧不能延伸出模座，当有必要时，在上模座上增加一块厚的板，固定在模座上承受弹簧力。

Clean the machine including the surface, base, slip board, groove, pressed board and oriented pole in the fixed time.

定期清洁机台表面、底板及下模滑板、沟槽、上模内压板及保险杆（注：必须关闭电源并恢复常温）。

Heel block wear plates should be tool steel on the bottom shoe and permanent graphite impregnated solid bronze material on the top shoe.

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。

Four guide posts and V iron standers make the equipment firmer and the location of die set and head more accurate .

该机采用四导向柱，槽钢机架使设备更加坚固，模具及压头定位更精确，采用底模定向垂直定向振动和上模加压振动，大大提高生产效率，且生产的砌块密实度均匀，强度高，该机是客户首选的理想机型。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
