A steel wire handle forming mechanism belongs to metal steel wire bending and forming machinery. The steel wire handle forming mechanism comprises a base, an acting cylinder, and an upper die frame. A group of stand columns are fixed on one side of the base, a lower die frame is fixed on the tops of the group of stand columns, and a demising cavity is formed in the middle of the lower die frame. A die head seat is fixed with the lower die frame. The upper surfaces of the die head seat are respectively provided with a handle foot forming groove, and the middle of the die head seat forms a die handle matching cavity. A die head is composed of a semi-cylinder and a die handle. Two sides of the semi-cylinder are respectively provided with a handle foot forming die slot, and handle foot forming dies are inserted in the handle foot forming die slots in an embedded mode. The die handle is formed on one side of the semi-cylinder. The acting cylinder is fixed on the base. Two steel wire placing devices are arranged on two sides of the lower die frame, wherein the two sides of the lower die frame face upwards. A crossing arm frame is fixed on one side of the upper die frame. A first crossing arm and a second crossing arm are connected on two ends of the crossing arm frame and connected with two sides of the upper die frame, and then a first crossing arm arc cavity and a second crossing arm arc cavity are formed respectively. Manipulation strength is lightened, efficiency is improved, quality is guaranteed, operation and maintenance are convenient, and cost is saved.
