Which is set up in the beginning of 1980,and developed with BasicA programming language based at the platform of DOS, the CAD/CAM System of Cold Press Dies is the outstanding CAD/CAM software that is proper to those small and medium-sized enterprises. But with the rapidly developing in the hardware and software of computer industry, it is forced to be faced to the being reformed or sifted out.

建立于80年代初期、在DOS平台上应用BasicA语言开发的冲裁模CAD/CAM系统是一个适用于中小企业使用的相当优秀的模具设计制造应用软件，但是随着计算机行业软件和硬件的迅速发展，使其面临着被改造或是退出历史舞台的命运。

A hydraulic self-sealed swab bing wellhead assembly with anticollision crown;2. An economical and safe casing swab bing tool;3. If sand is not sunk, by operation of swab to build a different pressure between up and down of sunk sand to form a de- terminate pressure stir makes the sand to sink to reach the objective of unstuck.

冲管解卡工艺是将小直径的管柱下入到油管中，在油管中建立液流的循环通道，利用该通道把砂子带到地面，一直冲洗到人工井底，给油管外的砂子下沉留有一定的口袋；若砂子不下沉，可以通过抽汲在沉砂上下建立压差，形成一定的压力激动，使砂子下沉，达到油管解卡的目的。

Just as human as to the general division of labor between the bladder and anus, this toilet can be stored each time the urine urine urine storage room in the toilet, and then the high pressure chamber for each of feces in the liquid carbon dioxide wash away, when the urine urine storage room to store a certain amount of time it will filter into the filter chamber, filter can also be used after red feces.

就如同人体般使膀胱与肛门分工合作一般，这种马桶可以将人每次小便的尿储存在马桶的储尿室中，然后将每次的屎用高压室中的液体二氧化碳冲掉，当储尿室中的尿储存到一定量时便会排入过滤室进行过滤，过滤后便也可以用来冲屎。

For high-speed flow of medium, open the gate in local conditions can cause the vibration Cast Gate, Globe, Check Valves of the gate, but they may damage the vibration damper and the valve seat sealing surface, while the throttling damper will suffer erosion of the medium.

对于高速流动的介质，闸板在局部开启状况下可以引起闸门的振动，而振动又可能损伤闸板和阀座的密封面，而节流会使闸板遭受介质的冲蚀。

And can reduce or eliminate the anisotropic material to improve the performance of its punch, so that elongation of the material significantly increased for deep-drawing deformation even provided a good internal organization.

且可以减轻或消除材料的各向异性，改善其冲压性能，使材料的伸长率显著提高，为均匀的深冲变形提供了良好的内部组织。

Wildly used in deep-drawing application, such as kitchen and household utensils, domesticresistance.

的开发，使该类产品在厨房设备、器皿、家用电器等深冲用途得到广泛应用。

A set of technological specifications fit for laser surface quenching have been obtained in view of the punching die of T12 steel lamp holder through heat tr-eatment, metallographies analysis and industrial application etc.
