Feed the gross pipe from front plant, cog down the upper roller to given size to rotating bring the pipe into rolling zone for reducing diameter and wall form rolling; after rolling from head to tail, turn 90Deg with the gross pipe, top bar and core head by tilter for next rolling travel that inverse roll to head to bring the pipe back to front plant; then, turn again for next periodical to-an-fro rolling till design size request.

将毛管自轧机前台喂入，将上轧辊压下至设定的尺寸，毛管在轧辊的旋转带动下曳入轧制区域，进行减径和减壁变形轧制；毛管从头部轧制到尾部后，将毛管、顶杆及芯头在翻转装置的作用下翻转90°，进行下一个轧制行程，反向轧制到头部，毛管回到轧机前台；再将毛管、顶杆及芯头在翻转装置的作用下翻转90°，进行下一个轧制周期往复轧制，轧制到毛管成达到设计尺寸要求。

Uses the straight guide pillar guidance, the throwout lever top material, the straight roof bar completed the drawing of patterns and has carried on the choice to mold's material.

利用直导柱导向，推杆顶料，直顶杆完成脱模并对模具的材料进行了选择。

It use two disparting surface,and its frame is fast.It use point moulding gob,so,it can fall off automatism.When it is pulled out ,the pulling pole pull the product and accomplish the pulling of its side concave . The design project is divided into two parts. The first part is about the working theory and application of a plastic injection mould, the principle of designing and the introduction of the production about plastic mould.

它采用双分型面分型，结构紧凑；采用点浇口，且浇口可以自行脱落；顶出时，由推杆和斜顶杆顶出制品并完成制品内侧凹的抽芯；模具定模上的水道以多支回路分别冷却，动模一侧的型芯由三组水道分别冷却。

On certain large area moldings it is often advantageous to use both parting surface pins and molding face pins.

某些大面积的塑件常常同时使用分型面顶杆和塑件面顶杆，这是有利的。

I For the ejection of certain types of circular mouldings.

塑件用中空的顶杆顶出的方式称之为顶管。

With the finite element method this *** analyzes influence factors of Lateral rigidity including layout and spacing of faade bracing, horizontal bracing and unusual arrangement of faade bracing firstly, revealing the change discipline of lateral rigidity. Then, on this basis, this *** further researches on frame Stability capacity and its influence factors such as semi-rigid node, bracing spacing, base transom height, distance between top transom and the supported matter, structure height, longitudinal distance between adjacent standards, distance between adjacent transoms, horizontal load, in order to find out the law of stability capacity, guiding the design and construction.

借助有限元本文首先分析立面斜杆的布置方式、布置间距、水平斜杆以及立面斜杆不正常布置等因素对架体抗侧刚度的影响，揭示抗侧刚度的变化规律；在此基础上，进一步考查了节点半刚性、斜杆间距、底排横杆高度、顶杆伸出长度、架体高度、立杆纵距、横杆步距、水平荷载大小等对架体稳定承载力的影响，以期得到承载力的变化规律，用来更好地指导设计和施工。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
