The steel bar diameter shrinking machine is a special equipment used for steel bar processing. It mainly reduces the local or overall diameter of the steel bar through cold processing, while maintaining the strength and toughness of the steel bars. It is widely used in construction, bridges, tunnels and other engineering fields.

Core functions

- Diameter reduction: Without changing the material of the steel bar, the diameter of the designated parts of the steel bar is reduced through mold extrusion, etc., to meet different connection or construction needs (such as steel bar joint length, making bolts, etc.).

- Strengthening performance: During cold processing, the internal crystal structure of the steel bar is densified after being extruded, the surface hardness and tensile strength are improved, while maintaining good ductility.

How it works

The working process mainly uses the motor to drive the mold to rotate or move in a straight line to extrude and shape the steel bars. By adjusting the mold size and pressure parameters, the diameter, length and diameter reduction parts of the steel bars after shrinking diameter can be accurately controlled, and is suitable for steel bar processing of different specifications (such as round steel, rebar) and materials.

Advantages

- High processing efficiency, continuous operation, suitable for mass production.

- Cold processing does not require high-temperature heating, saves energy, and avoids performance changes caused by high temperature of steel bars.

- The steel bars are connected firmly after shrinking diameter, which can replace traditional welding or mechanical connection methods and simplify the construction process.
