The utility model relates to the field of unmanned aerial vehicles, in particular to a fire emergency rapid loading and unloading unmanned aerial vehicle. The technical problem to be solved by the utility model is to provide the fire-fighting emergency rapid loading and unloading unmanned aerial vehicle which can be used for rapidly unloading, shortening the emergency response time and meeting the rapid material delivery requirement in a complex environment in a fire-fighting scene. A fire-fighting emergency rapid loading and unloading unmanned aerial vehicle comprises an unmanned aerial vehicle body. The loading and unloading device is fixedly arranged below the unmanned aerial vehicle body; the loading and unloading device comprises a connecting frame fixedly connected to the lower end of the unmanned aerial vehicle body. A fixing plate is arranged at the lower end of the connecting frame and fixedly connected with the connecting frame through bolts. At least two electromagnetic rods are further arranged at the lower end of the fixing plate and fixedly connected with the fixing plate through bolts. According to the utility model, the effects of quickly unloading, shortening the emergency response time and meeting the requirement of quickly delivering materials in a complex environment in a fire-fighting scene are achieved.

A kind of hydraulic bulging process for thick-walled cylinder instability control belongs to hydraulic bulging technical field, overcome the defect that instability easily occurs in existing thick-walled cylinder hydraulic bulging process, comprising the following steps: S1, blank pretreatment;S2, determine the judging basis of blank hydraulic bulging instability;S3, finite element simulation modeling and parameter setting;S4, mold assembly and blank installation;S5, hydraulic bulging, in the process of hydraulic bulging, the shape size data of blank is monitored in real time by visual displacement sensor, if it is found that blank occurs bulging, concave waist or horn shape instability phenomenon, immediately stop bulging process, unload and accurately measure the shape size of blank, according to the shape shape and size measurement result of blank, adjust the loading rate of upper punch, then blank is reloaded on the force-reducing hydraulic bulging die, continue to bulge processing to blank.The present application effectively suppresses bulging, concave waist, horn mouth and other instability phenomena, realizes the uniform deformation of thick-walled cylinder bulging process.
