Tin breaking equipment for superfine tin wires

The invention relates to the technical field of welding equipment, in particular to superfine solder wire tin breaking equipment which comprises a machine body, a first guide mechanism, a tin breaking mechanism and a second guide mechanism, the first guide mechanism, the tin breaking mechanism and the second guide mechanism are sequentially arranged on the machine body in the first direction, and the tin breaking mechanism comprises a guide column and a wire pressing wheel. A traction space is defined between the two spiral tangent planes. According to the tin breaking equipment for the superfine tin wire, the guide column is matched with the wire pressing wheel, and due to the limiting effect of a traction space defined by two spiral tangent planes, the tin wire is clamped in the traction space and cannot move, so that the tin wire is in a static state relative to the wire pressing wheel, the phenomenon that the tin wire moves relative to the wire pressing wheel and missed punching occurs is avoided, and the
