The main transmission box of the steel bar straightening machine
and the traction pressure roller, the transmission box is organized by mechanical deceleration to reduce the motor speed, and drive the active pressure roller (upper pressure roller) to rotate.
When loading the material, roll a migraine handle to lift the upper pressure roller, pass the steel bar through the V-shaped groove between the upper pressure roller and the lower pressure roller (passive pressure roller), and then roll the migraine handle in the opposite direction to make the upper The pressure roller is lowered, and the upper and lower pressure rollers are in a state of clamping the steel bars.
The material is pressed between the two pressure rollers, and the strength of the adjusted steel bar depends on the clamping force between the pressures. A tension spring is connected to the connecting rod mechanically connected to the upper pressure roller. The tension spring applies pressure to the upper pressure roller. The traction force of the pressure roller is proportional to the pressure. Therefore, different tensions should be selected for steel bars of different diameters and materials.
Spring pressure, and then better hold and pull the rebar. At the same time, in order to prevent continuous cutting during shearing, when the steel bar is stopped by the top, there should be obvious slippage between the steel bar and the pressure roller. Therefore, the adjustment of the tension spring pressure is the key to the normal operation of the steel bar straightening machine.
