The utility model is owing to the cutting mechanism that adopts technique scheme to existing concrete-bar straightening-cutting machine is improved, behind electric motor starting, master in energy-storing flywheel and the cutting mechanism, driven gear rotates, this moment, electromagnetic clutch was in off-position, the inserted sheet that stops in the cutting mechanism stops that dialling plate control ratchet leaves ratchet, therefore rotating shaft this moment is not rotated, knife rest is also slack, electric motor starting, by corresponding band transmission, the chain transmission drives the straightening reversing frame high speed rotating of straightening mechanism and drives two pairs of conveying rolls rotations in front and back of haulage gear, the introducing port of reinforcing bar the past conveying rolls front end is sent into after preceding conveying rolls traction is carried and is entered the straightening reversing frame, by the some straightening die sleeves that are installed on the straightening reversing frame reinforcing bar is carried out straightening, the setting of the fairlead of straightening die sleeve front end, being convenient to reinforcing bar enters in the straightening die sleeve smoothly, enter the back conveying rolls through the reinforcing bar after the straightening of straightening reversing frame and further be pulled conveying, reinforcing bar passes cutting mechanism driving gear axle center through hole and arrives material bearing shelf when touching the baffle plate of signal generator through the flywheel axle center, baffle plate deflection inductor sends signal, the control electromagnetic actuation, the plate that stops in the cutting mechanism separates with group plate, the ratchet that ratchet rotating shaft in the driven gear is hinged resets rapidly and ratchet engaged under the pulling force of back-moving spring, making rotating shaft rotate with ratchet and drive knife rest by capacity eccentric bearing simultaneously moves, because the energy-storing flywheel high speed rotating provides enough kinetic energy to make driven gear drive the knife rest fast moving reinforcing bar is cut off, cutting knife is easy damaged not, after the bar cutting, because casing, cutting knife and ground inclination, reinforcing bar is cut off the back and is released material bearing shelf, the baffle plate of signal generator resets under action of reset spring, the electromagnetic clutch outage, knife rest resets, stopping inserted sheet and dialling plate just makes rotating shaft stop operating, finish a working cycles, limit shaft is enclosed within to make under the support of push rod and dials plate and can not shake, this utility model is improved existing concrete-bar straightening-cutting machine, has the following advantages:

1. because this concrete-bar straightening-cutting machine has been set up energy-storing flywheel, reduced energy consumption;

2. owing to the improvement to cutting mechanism makes the reinforcing bar end face of cutting off neat, error reduces;

3. owing to establish ratchet in the driven gear, maintain and replace need not be changed driven gear only to ratchet, and is easy to maintenance, and cost reduces;

4. because cutting mechanism tilts to install the reinforcing bar of cutting off is fallen on the material bearing shelf at an easy rate, easy for operation.
