在對冷拔無縫鋼管（guǎn）開展生產解決過程中，通常也要開展準譜兒的蛻變（biàn）采用相應辦法解決，管理在繼續的運用過程中開展相（xiàng）對更好的（de）采用，這樣的（de）話在對冷拔無縫鋼管是怎（zěn）麽樣（yàng）開展蛻變（biàn）采（cǎi）用（yòng）相應辦法（fǎ）解決的呢?當凸模需要與冷（lěng）拔無縫無縫鋼管進行聯（lián）係（xì）時，冷拔無縫鋼管進行首先躬身行（háng）禮（lǐ），在凸模圓角位置材料出現脹突變形出現強大化。凸（tū）模（mó）接著需要，這陣兒，冷拔無縫無縫鋼管有關於兩種蛻變（biàn）的（de）或許，一是凸模底邊毛坯在兩向拉剪（jiǎn）應力教（jiāo）育發出生進行增長蛻變，大概積進行增長，厚薄（báo）減薄，即脹突變形;二是法（fǎ）蘭（lán）單位毛坯在切向壓剪（jiǎn）應力（lì）、通往拉剪應力教育下，通過完整過程凹模圓角向直壁的進（jìn）行起伏，大概積減少，厚薄（báo）進（jìn）行（háng）增長，即（jí）拉深蛻（tuì）變。
In the production process of cold-drawn steel pipe, it is generally necessary to do some deformation treatment in order to make better use in the subsequent application process. Then how to do deformation treatment for cold-drawn steel pipe? When the punch drops and contacts with cold-drawn seamless steel pipe, the cold-drawn steel pipe bends at the beginning and at the rounded corner of the punch. Expansion and hardening occur in the site material. There are two kinds of deformation possibilities for cold-drawn seamless steel pipe when the punch continues to drop. One is that the blank at the bottom of the punch will elongate under two-way tension stress, the general product will increase and the thickness will decrease, i.e. the bulging deformation; the other is that the blank at the flange sector will straighten through the round corner of the concave die under tangential compressive stress and radial tension stress. The wall flow, general area reduction, thickness increase, that is, deep drawing deformation.
當冷拔無（wú）縫鋼管（guǎn）拉深蛻變障礙物與脹突變形（xíng）障礙物相那時候，底邊的脹形將與法蘭（lán）處的拉深與此同時開展（zhǎn）。若拉深蛻變（biàn）障礙（ài）物低於脹突變（biàn）形（xíng）障（zhàng）礙物，底邊和壁部（bù）的毛坯將僅此而已出現蛻變，法蘭處的毛坯向直壁轉到逐漸形成筒壁，拉深蛻變可以需要開（kāi）展，截至蛻變進行齊備。若拉（lā）深蛻變障礙物（wù）除（chú）夕於底邊或（huò）縫部脹（zhàng）突變形障礙物，則將出現脹突變形。
When the deformation resistance of cold-drawn steel pipe is equal to that of bulging deformation, the bulging at the bottom will proceed simultaneously with the drawing at the flange. If the drawing deformation resistance is less than the bulging deformation resistance, the blank at the bottom and the wall will not deform. The blank at the flange will transfer to the straight wall to form the cylinder wall, and the drawing deformation will proceed smoothly until the deformation is completed. If the deformation resistance in deep drawing is greater than that in bottom or joint, the bulging deformation will occur.
其主要原因在於冷拔無縫鋼管脹突變形整體（tǐ）水平著名，職是之（zhī）故這一類型的情（qíng）況蛻變臉型的成為意味著著散攤子的（de）進行起（qǐ）步。職是之故，正常化的拉深（shēn）完整過程是躬身行禮、脹形、拉深的蛻變完整過（guò）程。要不然，則為躬身行禮、脹（zhàng）形、拉深、脹形、散（sàn）攤子的完（wán）整（zhěng）過程。躬身行禮蛻變在拉深完整過程（chéng）中一直仍然存在。脹突變（biàn）形如（rú）果仍然存在於蛻變現在（zài），如（rú）果仍然存（cún）在於進行加工的（de）全完整過程，如果與拉深蛻變瓜代開（kāi）展截至蛻變（biàn）進（jìn）行齊備或機件（jiàn）分裂。
Because the expansion deformation level of cold-drawn steel tube is limited, the change of deformation means the beginning of splitting. Therefore, the normal drawing process is the deformation process of bending, bulging and deep drawing. Otherwise, it is a process of bending, bulging, drawing, bulging and splitting. Bending deformation always exists in the process of deep drawing. Bulging deformation exists either in the initial stage of deformation, or in the whole process of processing, or in the process of substitution with deep drawing deformation melon until the end of deformation or cracking of parts.
在對冷拔（bá）無縫鋼管（guǎn）開展進行加工采用相應辦法解決的完整過程（chéng）中也是進行比較比較容（róng）易發生一（yī）部分玩忽職守（shǒu）的，因此這即將求（qiú）我（wǒ）們在冷（lěng）拔無縫鋼管開展生產的完整過程中有必（bì）要進行理會了，盡可能較少一部分進行裂縫的出現。
In the process of processing cold-drawn steel pipe, there are also some drawbacks, so it requires us to pay attention to the production process of cold-drawn steel pipe and try to reduce the occurrence of some defects.
