The invention discloses a steel wire bending forming machine. According to the technical scheme, the steel wire bending forming machine is characterized by comprising a horizontal prepressing device, a vertical prepressing device, a wire guiding device and a bending forming device which are arranged on a machine frame and allow steel wires to pass in sequence. The wire guiding device is connected with a driving assembly used for driving the wire guiding device to operate. The bending forming device is connected with a shearing device for cutting the steel wires. The shearing device is connected with a cam assembly used for driving the shearing device to do reciprocating movement. According to bending angles of the steel wires and bending treatment in the different directions, products with different shapes and angles can be produced automatically through the rotating radian of a working rotary table driven by a power transmission assembly on the machine frame, continuous bending machining treatment is conducted on the steel wires by different angles, accordingly, the steel wire continuous bending procedure is carried out, and the product forming efficiency is greatly improved.
