Crank Crop Flying Shear Machine
The type of flying shear machine belongs to the crop shear and it is the indispensable equipment in the continuous rolling mill production line. The basic characteristics of the crank crop shear are that it is frequently started and braked under small inertia, and shearing is achieved under large inertia. The shearing process of the flying shears mainly includes head cutting, tail cutting, cutting (double) length, and accident treatment and sample cutting of the rolled parts on the continuous rolling line. The crop shear produced by TINVO mainly includes: crank lever crop shears, rotary crop shears, crank connecting rods and rotary combined flying shears, big gantry flying shears, etc.
| Comparison of Hot Billet Crop Shear | |
| Crank Type | Rotary Type |
| DC motor, stable rotary speed | AC motor |
| DC Start-stop control précised positioning | Air clutch brake, the mechanical clutch is easy to wears up during long periods of continuous working. |
| Low power consumption, no power consumption when the motor standby stops. | High power consumption, the motor has no start-stop control and must work continuously and consume the power |
| Cutting section ≤Φ80mm | Cutting section ≤Φ60mm |
| Maintenance-free, | More consumable parts like Clutch piece, the routine maintenance waste more money and time |
| Longer lifespan, triple time of rotary type | Shorter lifespan |
| Good quality cutting section, the upper and lower blades are always parallel to each other and upright to billet. | Poor quality cutting section, the upper and lower blades are not upright to billet and have changeable distance |
| New Generation | Last Generation, belong to eliminate products in China |
