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 debation 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 b (because the external force, the change of humidity etc.) and debation, internal force attack each other in effect among the various parts of an b, to resist the external effect, and strive to make the b from the debed range back to the pre debation 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.

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 b of cold the production equipment and the late repair are very favorable.
Matters needing attention锛�
The cold bending machine belongs to the hydraulic machinery. Some people ask, why is there electric power? The electric cold bending machine also transbs 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 perbance. So how do the cold-bending machines apply to those projects?
We will definiby 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 compleby 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 debation 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 immediaby 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 immediaby and the power supply should be cut off.
