The invention discloses a German-style hose hoop assembling machine. The assembling machine comprises a machine table, a front rotating disc, a rear rotating disc, a front rotating mechanism, a rear rotating mechanism, a hoop shell feeding mechanism, a strip material feeding mechanism, a hoop shell flattening mechanism, a welding mechanism, an edge coiling mechanism, a screw feeding mechanism, a screw screwing mechanism and a discharging mechanism, wherein a mover of the front rotating mechanism is connected with the front rotating disc, a mover of the rear rotating mechanism is connected withthe rear rotating disc, the outer side of the front rotating disc is sequentially provided with the hoop shell feeding mechanism, the strip material feeding mechanism, the hoop shell flattening mechanism, the welding mechanism and the edge coiling mechanism in the rotating direction of the front rotating disc, and the edge coiling mechanism, the screw feeding mechanism, the screw screwing mechanism and the discharging mechanism are sequentially arranged in the outer side of the rear rotating disc in the rotating direction of the rear rotating disc. According to the German-style hose hoop assembling machine, the automaton degree is high, and the normal work of the German-style hose hoop assembling machine can be realized only by one person, so that the problem that the labor cost is too high is effectively solved.
