冷彎機(jī)，是以型鋼為原料、通過連續(xù)冷軋成型。生產(chǎn)復(fù)雜斷面型材，并可根據(jù)客戶要求設(shè)計(jì)、制造不同規(guī)格的冷彎設(shè)備。行業(yè)施工中用數(shù)控冷彎機(jī)進(jìn)行型鋼加工，是鋼拱架制造的必選設(shè)備。
冷彎機(jī)可用于工字鋼、礦工鋼、U型鋼、C型鋼、角鋼、槽鋼、道軌、方鋼、鋼管等型鋼的拱形卷圓、變徑、定角彎曲。數(shù)控冷彎機(jī)主要應(yīng)用于隧道，地鐵，水電站，地下洞室等工字鋼，槽鋼彎曲。數(shù)控冷彎機(jī)采用數(shù)顯編碼器編程，使液壓操縱系統(tǒng)定位準(zhǔn)確，所彎型鋼一次自動(dòng)成型，效率高、操作方便。
冷彎機(jī)構(gòu)成（工作原理）：
 1、冷彎機(jī)是地道支護(hù)鋼拱架加工制造的新式設(shè)備。數(shù)控冷彎機(jī)由底座、機(jī)械傳動(dòng)、冷彎體系、液壓體系、電器控制體系和輔佐體系等六大有些構(gòu)成。數(shù)控冷彎機(jī)工作時(shí)，將所需冷彎加工的型鋼由輔佐體系的門式托架推放在兩自動(dòng)滾輪之間，發(fā)動(dòng)數(shù)控冷彎機(jī)液壓體系使液壓缸推進(jìn)燕尾槽和冷彎滾輪冷壓型鋼，待到達(dá)規(guī)劃所需弧度時(shí)封閉液壓體系，發(fā)動(dòng)數(shù)控冷彎機(jī)機(jī)械傳動(dòng)體系，使自動(dòng)滾輪滾動(dòng)并依托摩擦力股動(dòng)型鋼平穩(wěn)緩慢前行，然后完成接連冷彎工作。在冷彎結(jié)束時(shí)，封閉數(shù)控冷彎機(jī)機(jī)械傳動(dòng)體系 ， 一起發(fā)動(dòng)液壓體系 ， 使液壓缸回收。將冷彎型鋼放置在輔佐體系的門式托架上即可。這種冷彎工作，確保了原料的強(qiáng)度， 提高了支護(hù)鋼拱架的質(zhì)量，極大地提高了工效，操作簡略、明晰。數(shù)控冷彎機(jī)與壓床相比，具有杰出的工作性能。
2、為了習(xí)慣一些較差地質(zhì)的施工工程區(qū)段，在地道的施工過程中，規(guī)劃上常常運(yùn)用鋼拱架來支持維護(hù)，為了習(xí)慣運(yùn)用鋼拱架的運(yùn)用數(shù)量增大，請(qǐng)求增高，然后規(guī)劃了數(shù)控冷彎機(jī)這種設(shè)備。它確保了接連工作的可能性，而且節(jié)省了很多的人力和物力。

冷彎機(jī)的對(duì)比
1）比如對(duì)于一節(jié)長9m的工字鋼拱架，工地原始辦法是用氧氣、乙炔每米割一個(gè)三角形缺口，用大錘敲打成弧形，但是這種做法破壞了工字鋼的整體性，留下了多處燒傷。
2）在附近地區(qū)的工廠加工。但常常存在工廠太遠(yuǎn)，運(yùn)輸不便，加工費(fèi)用高等問題，加大了成本。
3）使用冷彎機(jī)。這種要簡單很多，只要將三相電引至加工區(qū)即可。雖然冷彎機(jī)投入近2萬元，然而相對(duì)近300t工字鋼的加工量來講，這種投入完全是值得的。況且冷彎機(jī)加工時(shí)是連續(xù)的，工字鋼之間全部電焊焊接，不存在下腳料，每加工9m可節(jié)約近50cm，成本大大降低。
 
冷彎機(jī)操作須知
1、將設(shè)備定放到一個(gè)基準(zhǔn)面上進(jìn)行校正，必須保持地面水平。
2、工字鋼必須在水平的工作臺(tái)上（帶有滾動(dòng)的工作臺(tái)）工作。
3、使用前必須加油（減速機(jī)加30#機(jī)油，10公斤；油箱加46#液壓油，50公斤，每月要更換新油）
4、電源連接是否符合標(biāo)準(zhǔn)
注意事項(xiàng)
1、電控箱、電液閥、行程開關(guān)等電器一定要保持清潔干燥，不得淋水。經(jīng)常檢查以上各部件的導(dǎo)線外套不得有破損，防止漏電。
2、搬運(yùn)機(jī)器時(shí)，不要有大的顛簸，不得隨意敲打機(jī)器的各部件。

The cold bending machine is made of type steel as raw material by continuous cold rolling. The production of complex section profiles, and can be designed and manufactured according to customer requirements of different specifications of cold bending equipment. For the steel processing industry in the construction of CNC bending machine, is the necessary equipment for manufacturing steel arch.
Cold bending machine can be used for steel, I-steel, miners U steel, C steel, angle steel, channel steel, rail, Fang Gang, steel and other steel arch roll round, diameter, bending angle. The numerical control cold bending machine is mainly used in the tunnel, the subway, the hydropower station, the underground cavern and so on, and the channel steel is bent. Numerical control cold bending machine adopts digital encoder programming to make the hydraulic control system accurate, and the curved steel is automatically bed in one time, and the efficiency is high and the operation is convenient.
Comb of the cold bending machine (working principle):
1, bending machine is a new equipment for tunnel support steel arch manufacturing. The NC cold bending machine consists of six parts, which are the base, the mechanical transmission, the cold bending system, the hydraulic system, the electrical control system and the auxiliary system. The work of CNC bending machine, steel bending required by door bracket system to help push it between two roller, hydraulic bending machine CNC system to launch the hydraulic cylinder to promote dovetail groove and cold bending roller cold steel, to reach a required radian when planning closed hydraulic system, a numerical control bing the mechanical transmission system, the automatic rolling friction and relying on the femoral artery smooth steel moving slowly, and then complete the series of cold work. At the end of the cold bending, the mechanical transmission system of the NC cold bending machine is closed, and the hydraulic system is launched to make the hydraulic cylinder be recovered. The cold-bed steel is placed on the door type bracket of the auxiliary system. The cold work, ensure the material strength, improve the quality of the support steel arch, greatly improves the work efficiency, simple operation, b. Compared with NC bending machine and press, with outstanding perbance.
2, to the construction engineering geological section of some bad habits, in the construction process of tunnel in planning often use steel arch to support maintenance, in order to use number of used steel arch increases, request increased, then planning CNC bending machine of this equipment. It ensures the possibility of continuous work and saves a lot of manpower and material resources.
