steel bar bending machine and cage machine in the first bridge of world

Itech stirrup bar bending machine, / pile cage making machine play an important role in bridge and foundation. The longest bridge in the world recorded in the Guinness Book of World Records before 2011 ,it was the Pontchartrain Bridge in the United States, with a total length of 38.4 kilometers.This bridge is located in Louisiana and connects New Orleans and Mandwell.

However, in 2011, the Guinness World Record was refreshed by a newly built bridge in our country China.Its length is more than four times as long as the Pontchartrain Lake Bridge, the world’s largest bridge!

This newly appointed longest bridge in the world is Dankun Bridge.

The Dankun Bridge is located in the Jiangsu on the east coast of China. It starts from Danyang, passes through Changzhou, Wuxi, and Suzhou, and ends in Kunshan.

Because the passing area is the rich southern Jiangsu area with a relatively developed economy, the bridge spans more than 180 roads of various types, making the construction difficult to imagine.

The first bridge of world has a total length of 164.851 kilometers. This length is very shocking. Even if it is driving by, it will take two or three hours!

Steel rebar shear line, also called cnc rebar shear line,rebar shearing line,automatic rebar shear line.

This steel rebar processing equipment is from Europea design.with its the reality of China market, rebar shear line widely use in rebar cut&bend.

 

It use a servo motor to adjust the distance between the cutting blade and the positioning baffle. The encoder is used for measurement, with a high accuracy of sizing, up to ±2mm. it make steel bar cut to length. The CNC steel bar shearing production line adopts the hydraulic shearing method, which is small in size, large in shearing force, and high output. Compared with the mechanical punching and shearing methods, it is low noise, long service life and stable operation of the equipment. at the same time, CNC rebar cutting line adopts oil cylinder to press the material, the pressure is large, the steel bar will not rotate when cutting, and the steel bar will be evenly cut. The hydraulic system adopts a new type of subwoofer plunger oil pump, and the oil tank has undergone special treatment, which greatly reduces the problem of stuck valve clogging.

 

The hydraulic cylinder adopts imported seals, which greatly increases the service life. Innovative design, compared with other manufacturers’ hydraulic shears of the same ton, the shearing capacity is increased by 1/3, which greatly improves the work efficiency; the new hydraulic system design, such as the hydraulic system of other manufacturers’ hydraulic shears to meet the technical requirements when cutting φ25 steel bars The working pressure must reach 25Mpa. The company’s hydraulic system only needs 15Mpa, which can meet the technical requirements. In comparison, itech hydraulic steel bar cutting line system greatly increases the service life.

 

Pneumatic system design concept for the steel bar cutting line, the main pipeline adopts stainless steel pipe transmission, reducing the compressed air loss; the solenoid valve is installed under the corresponding control cylinder, the response speed is fast.

The number and specifications of the steel bar can be set Etc.

The technical parameters of the automatic steel rebar shear line

produced by ITECH:

• Shearing steel bar diameter range: Φ12～40mm;
• Shearing length range: 1～12m;

Pile rebar cage making machine in steel  cut and bend factory

CNC steel cage welding machine is for steel processing and making steel cage.it is controlled by PLC.With CNC steel cage welding machine and rebar stirrup bending,it ended the history of manual binding of steel cages.It has improved the efficiency to make bridge and high-speed railway.it is wildly use in construction site, precast company, concrete company and steel cut and bend factory.

FIrstly according to the construction requirements, the main steel reinforcement of steel cage is fixed by manually. It have fixed rotating disk and mobile rotating disk.

1. steel bar pass through the corresponding template circular hole of the fixed rotating disk.
2. fixthe corresponding hole of the moving rotating disk.
3. Wind the spiralwire head to main bar.
4. The rotating disk and the mobile rotating disk rotate (the moving disk rotates while moving back), and simultaneously welds to form the product reinforcement cage

this is the bored pile reinforcement cage welding machine, that is The working principle of “rebar cage forming machine”.It has feature as following:

◆ Fast processing speed: usually, the material preparation and cnc cage welding parts are divided into two shifts. 10 people can process more than 20 pieces 12-meter-long rebar cage (material preparation, seam welding, reinforcement installation, detection Tube installation, guide pad installation, etc.), the work efficiency is very high.

◆ The processing quality is stable and reliable: due to CNC mechanization, the spacing between the main reinforcement and the winding reinforcement is unifor. the diameter of the steel cage is the same, and the product quality fully meets the specification requirements. In practice, when manually producing steel cages, engineering supervisors go to the processing site for inspections almost every day. when the use pile cge making machine, the supervisors basically implement “inspection-free” on the mechanized steel cages.

◆ There is no need for lap joints to tighten the stirrups, which saves 1.5% of materials compared to manual work, and reduces construction costs.

◆ Since the main reinforcement is evenly distributed on its circumference.it is convenient when multiple reinforcement cages connect. It saves lifting time.

◆ The pile cage making machine is guaranteed in terms of quality control.
