Description

Technical Field

[0002] In the field of metal processing, metal bars such as round steel are often cut. The commonly used cutting method is to use a round steel cutting machine for cutting. The diameter of the round steel is also different. Cutting large diameter round steel requires relatively high shearing force, and the stability of the round steel during shearing must be guaranteed, because the round steel will vibrate when it is cut, and the vibration will cause the cross-section to be large inclination and poor roundness, which will bring difficulties to subsequent processing. The existing round steel cutting mechanism is mostly driven by a motor to rotate, that is, the motor drives the large pulley to rotate, the large pulley drives the gear shaft to rotate, the gear shaft drives the gear to rotate, the gear drives the eccentric shaft to rotate, the eccentric shaft drives the connecting seat to move repeatedly, the connecting seat drives the connecting rod to move, and the connecting rod is equipped with a shearing blade, so that the round steel is cut by repeated movement. The force generated by this cutting machine is small, and it is only suitable for the shearing of small diameter round steel. Cutting large diameter round steel not only fails to achieve a satisfactory shearing effect, but also causes serious wear of the cutting machine and reduces its life. Therefore, in view of the above problems, a cylindrical steel cutting blank making mechanism is proposed. Utility Model Content
