The finished product can sometimes feature special shapes, such as deep drawing or folds at the ends, to be implemented in the production line.

Through the realization of suitable forming stations/ molds, we can complete the products without the need for later off-line processing.

Bending is a metal forming process in which a force is applied to a piece of sheet metal, causing it to bend at an angle and form the desired shape. A bending operation causes deformation along one axis, but a sequence of several different operations can be performed to create a complex part.

In press brake forming, a workpiece is positioned over the die block and the die block presses the sheet to form a shape. Usually bending has to overcome both tensile stresses and compressive stresses. When bending and forming is done, the residual stresses cause the material to spring back towards its original position, so the sheet must be over-bent to achieve the proper bend angle. The amount of spring back is dependent on the material, and the type of form. When sheet metal is bent, it stretches in length. The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend. The bend radius refers to the inside radius. The formed bend radius is dependent upon the dies used, the material properties, and the material thickness.

Bending machines are developed for high flexibility and low setup times. Those machines are able to bend single pieces as well as small batches with the same precision and efficiency as series-produced parts in an economical way.

Rebar bending machine is one of the necessary equipment for rebar processing. It is mainly used in the bending of rebar in all kinds of construction projects. Portable rebar bending machine is usually used with the cutting machine. Its application is very extensive. With the effect of the national investment, especially the country vigorously develops the high-speed rail, the production and sales of CNC rebar bending machine are increasing rapidly. Similar to other rebar cutting machines, bending hoops and straightening and cutting machines, the production base of this kind of machinery has been formed. Most of the products made in China can meet the needs of users, but the quality of some products cannot meet the requirements of the national standard.

The construction of the machinery industry in China has been developing rapidly in recent years. On the one hand, it is a reason to improve the quality of its own products and the low cost of domestic labor by introducing foreign advanced technology. On the other hand, the implementation of active fiscal policy for many years in the country is the fundamental cause of the growth of the industry.

The structure of rebar bending machine of each manufacturer is basically the same. The transmission scheme of rebar bending machine has the following 2 kinds: "a worm gear with one or two gears and a worm gear drive" and "13 gear transmission". The transmission efficiency of rebar bending machine with worm drive is not as good as the bending machine of the gear transmission. That is to say, the bending machine of the gear transmission is more relaxed with the diameter of the rebar under the same driving motor power condition. But the self-locking characteristic of the worm wheel and worm drive makes the positioning accuracy of the bending in the work much higher. At present, the production and application of rebar bending machine with "one or two grade gear and worm gear drive" are more common and the market share is high.

1. The CNC rebar bending machinemust have product specifications, certificates of conformity and maintenance records, it should be installed on a stable ground, and its cable insulation is good. Zero protection should be reliable. There should be enough sites for stacking steel reinforcement around the machine.
2. Both the belt pulley and the exposed gear must have a protective cover.
3. Before using, it is necessary to check whether the shock protector works effectively, whether the blade has cracks, and we also should make sure that the nut for fixing the blade is firm and not loose.
4. When the rebar bending and cutting machinedoes not reach the normal speed, it can not cut the material. When cutting the material, the operator's hand should only be placed on the side of the rebar which is near the worker's body, and the two ends of the rebar should not be cut with both hands. When the long rebar is cut off, the other side should be especially helped by a professional person to stabilize the reinforcement.
5. When operating, we should use both hands to hold the reinforcing brand aim at the edge of the knife. When the blade comes down and we feels a little press, it is necessary to press the steel bar immediately, so as to avoid hitting the end with the end up.
6. When cutting short material, the length of one part which held in the hand should not be less than 40 cm, and the distance between the hand near the blade and the blade should be kept more than 15 cm. If the part which held by hand is less than 40 centimeters, the short rebar must be pressed down by the casing to prevent injury when cutting.
7. The cutting materials should be cleaned in time. It should be stacked in order according to different specifications.
8. When we operate the machine, it is strictly prohibited to use hand to remove the broken ends and debris near the edge of the knife directly. The people around the machinery who are not professional are not allowed to stay.
9. It is forbidden to cut rebars and red-burning rebars whose diameters exceed the mechanical regulations. When multiple bars are cut off at one time, the section of rebars must be converted.
10. When it is found that the mechanical operation is abnormal or the abnormal sound or the blade is skewed, the machine should be stopped immediately. Workers should pull the sluice to break the power, report the repair of the machine repair personnel, and not repair it without authorization.
11. Operators at night should have adequate lighting, the height of lamps and lanterns is not less than 5 meters and their bulbs should be protected and they should be outside the dangerous areas on both sides of the factory.

The stirrup is one of the basic components when constructing the structure of the building. Normally we use stirrups to fix the other vertical ribs. The more complex the building is, the more types of stirrups are to be used. The stirrups are roughly divided into two types by materials, one is a circular stirrup, which is made from bending the plain bar;

Another type of ribbed stirrup is formed by bending a cold rolled ribbed steel bar. When there is no CNC machine, people can use simple machinery to make stirrups, but the efficiency is very low. With the increasing use of stirrups in the building construction, the traditional work methods became more and more unable to meet the requirement for production. At this point of time, the CNC stirrup bending machine was born, its high efficiency and good quality of bending have been sought after by many manufacturers. Generally, the opportunities for stirrup bending exist in two places, one is a construction site, and the other is a stirrup processing and distribution center. The CNC rebar bender is one of the essential production machines for steel processing enterprises. Because they are professional organization for processing steel bars, the requirement for the performance of machine is very high.

The stirrup bending machine is a processing machine aimed at steel work. It is an extension of the steel bending machine which is more efficient to achieve the specified angles and specifications. Most of the stirrup bending machine is CNC stirrup bending machine. The CNC bending machine is divided into semi-automatic bending machine and automatic stirrup bender machine. The stirrup bending machine is mainly used for building cold-rolling ribbed steel and hot-rolling three-grade steel. And the hooks and hoops for cold-rolling plain bars and hot-rolling circular steel bars. The automatic bending machine has the advantages of low failure rate of equipment use, fast speed of steel bar bending, low energy consumption without damaging ribs, low noise and light vibration; it has the characteristics of high efficiency application, reliable operation and so on. Double operation, light and flexible, 3-5 times manual bending.
