一般來講，冷彎就是用冷彎機(jī)彎的，不加熱；而熱彎需要加熱，所以其中就只有一個區(qū)別：冷彎有應(yīng)力熱彎沒有。那么什么叫做應(yīng)力呢？當(dāng)材料在外力效果下不能進(jìn)行位移時，它的幾許形狀和尺度將發(fā)生改變，這種形變就稱為應(yīng)變。材料進(jìn)行形變時內(nèi)部產(chǎn)生了大小相等但方向相反的反效果力反抗外力；把散布內(nèi)力在一點的集度稱為應(yīng)力，應(yīng)力與微面積的乘積即微內(nèi)力或物體因為外因(受力、濕度改變等)而變形時，在物體內(nèi)各部分之間發(fā)作相互效果的 內(nèi)力，以反抗這種外因的效果，并力求使物體從變形后的方位回復(fù)到變形前的方位。
此類機(jī)器能彎曲的材質(zhì)除去工字鋼外還適用于礦工鋼、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。
最終，消費者一定要謹(jǐn)記的是，在工字鋼冷彎機(jī)的選購中，不只需留意設(shè)備質(zhì)量的好壞，最主要的是要挑選有售后保證的廠家收購，以保證冷彎設(shè)備這種大型設(shè)備在買回去今后有較好的質(zhì)量保證，而且這樣做對于冷彎設(shè)備的正常投入出產(chǎn)及后期的保護(hù)、修理也十分有利。
注意事項：
同樣，礦山，水利、引水涵洞等工程是一樣的，對于冷彎機(jī)的需求是一定的，那么為什么冷彎機(jī)行業(yè)一直處于尷尬的狀態(tài)，就廠家而言冷彎機(jī)銷量和產(chǎn)品的重要性一直屬于附屬產(chǎn)品，主要是因為，冷彎機(jī)在工地上使用時必然的，但是就冷彎機(jī)的使用情況來看，一臺冷彎機(jī)使用壽命相對較長，同時，價格上來講，廠家的利潤不大，如果僅僅依靠冷彎機(jī)這一款產(chǎn)品來發(fā)展是不太現(xiàn)實的。
Generally speaking, cold bending is done by cold bending machine without heating, while hot bending needs heating, so there is only one difference: cold bending, stress and hot bending. So what's called stress? When the material can not be displaced under the external force, the shape and scale of the material will change, which is called strain. Material deformation which are of equal magnitude but opposite effect against external force; spread force at a point set of product is called stress, stress and micro area of micro force or object (because the external force, the change of humidity etc.) and deformation, internal force attack each other in effect among the various parts of an object, to resist the external effect, and strive to make the object from the deformed range back to the pre deformation range.
This machine can bend the material removed I-beam also apply to miners steel, U steel, C steel, angle steel, channel steel, rail, Fang Gang, steel and other steel arch roll round, diameter, bending angle.
The main parameters of WGJ-250 cold bending arch machine:

Total power: 12Kw voltage: 380V
Pressure of hydraulic system: 20Mpa
Oil cylinder propulsion speed: 1-13mm/s
Main drive wheel speed: 7r/min
Minimum bending radius 2m
在選購冷彎設(shè)備時，要看設(shè)備的各零部件是不是設(shè)備到位，是不是出現(xiàn)松動，是不是部件有銹蝕表象，假如出現(xiàn)零部件松動、有銹蝕表象，哪怕是纖細(xì)的也最佳不要收購，因為這樣的冷彎設(shè)備也許是他人用過的舊貨，也許是存放較長時間沒有用的設(shè)備，所以在收購冷彎設(shè)備時一定要細(xì)心調(diào)查、問詢。
Secondly, when choosing the cold bending equipment, the equipment can be launched to investigate and listen to whether the work is normal. If Huang Lang heard that chaos ring bending equipment inside individual components is not sensitive, or loose fall bad appearance, this should particularly pay attention to this, don't buy cold equipment.
Finally, consumers must keep in mind that, in the purchase of I-beam machine, not only need to pay attention to the quality of the equipment, the most important is to ensure the selection of customer service to ensure the acquisition of manufacturers, the cold equipment of large equipment in the future to buy back a better quality assurance, and to do so for protecting the normal input of cold the production equipment and the late repair are very favorable.
Matters needing attention：
The cold bending machine belongs to the hydraulic machinery. Some people ask, why is there electric power? The electric cold bending machine also transforms the electric energy into the potential energy of the hydraulic oil, and finally comes to the cold bending machine to do the work and achieve the proper performance. So how do the cold-bending machines apply to those projects?
We will definitely see bender in the tunnel construction, tunnel construction will need to bend and I-beam, tunnel reinforcement, a series of processes, shotcrete and so on, to the inner wall of the tunnel reinforcement, so the tunnel construction is cannot do without bending machine, but appears to be important in bending machine, tunnel construction it is a two Taiwan is completely sufficient. When we use the I-steel cold bending machine, we need to choose the cold bending machine for the quantity and progress of the engineering.
Similarly, mining, water conservancy, water diversion culvert project is the same, is certain for bending machine needs, so why bending machine industry has been in the awkward state, on the importance of bending machine manufacturers sales and products has always belonged to the ancillary products, is mainly because the bending machine used on our site is inevitable, but use of a cold bending machine, bending machine with a relatively long service life, at the same time, in terms of price, the profits of manufacturers is not big, if only rely on the product to the development of bending machine is not too realistic.
The use of cold bending machine in engineering has influenced the sales of other products, such as tunnel construction, need cold bending machine will require Tunnel Shotcreting car, also need some other engineering machinery, like rig, excavator, loader, engineering machinery and equipment, so many manufacturers rely on small products such as bending machine to open other high profit products to market development. Cold bending machine has an important significance in such a role, as well, it is also playing an important role in various projects. .
The I-steel cold bending machine has played a good role in promoting and promoting the automation of the profile processing. The I-steel cold bending machine is developed on the original bracing bed. Generally, there are three bracing heads, arranged on the same plane, and maintaining a certain interval between each other. The commonly used bracing beds for I-steel cold bending machine can be divided into two types:
(1) the center is a moving head, and the two sides are static bracing heads. This kind of bed support dynamic support head is driven by a crank or eccentric, capable of reciprocating motion, so as to exert a force on the contradict profile; static hold head was support profile processing, but in order to meet the needs of the processing section of different size, the static hold head made before and after adjustment.
(2) the center is a static bracing head, and the two sides are moving brace heads. The supporting head of this kind of supporting bed is mostly driven by the oil cylinder, so the supporting head is actually an extension part of the cylinder piston rod, and its stroke can be regulated by the oil flow into the cylinder. The motion of the two brace heads needs to be kept in synchronization so that the bending deformation of the profile and the static bracing head are symmetrical.
During the operation of the I-steel cold bending machine, the operation rules should be strictly observed, and the operation should be stopped immediately and the reasons for stopping the machine should be stopped. At the same time, after the working of the I-steel cold bending machine, the oil pump should be closed immediately and the power supply should be cut off.
