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.

First The role of stirrups

reinforcement concrete beams and columns are indispensable for stress and erection reinforcement. They are necessary conditions to ensure that the concrete beams and columns are stable and firm under tension and compression. However, when the beam is under force, have difference strength. One is the upper part compressed,second the lower part pulled, and third shear stress is generated on the oblique section.

Stirrups are also indispensable in not only beams but also columns. Although under normal circumstances the column does not need to bear a large lateral load, once an earthquake occurs, the role of stirrups will not be replaced!Second, the problems that should be paid attention to during the use of stirrups.

How to determine the number of stirrups?

Because the oblique section shear stress is the largest at the fulcrum, not only the oblique reinforcement must be installed, but the number of stirrups will also increase, which is twice the number of other parts of the beam. Generally, the spacing of stirrups at the mid-span of the beam is 200mm, and the spacing of the stirrups at the beam-column node is 100mm.

What is the length of the stirrup encryption zone? What is the diameter?The length of the stirrup densification zone is 1.5 times the beam height or column section size and not less than 500mm. The diameter is not less than 1/4 of the diameter of the beams and columns to which it is fixed, and not less than 6mm.steel stirrup bender

As we all know, there are two types of steel rebar stirrup bender. One is S type, this is type used anti-twist system, also called advanced feeding system. It is feature as s shape rebar feeding. Another is line type.it is traditional type. It is feature with horizontal straightening and vertical straightening system.let see difference between anti-twist rebar stirrup bender and common stirrup rebar bending machine
