Off-line testing device for wire-bundling head and use method of off-line testing device

The invention relates to an off-line testing device for a wire bundle head, which is provided with a matched to-be-tested wire bundle head and comprises an upper annular closed bearing guide groove, a lower annular closed bearing guide groove, a straight guide groove, a short guide groove, a hydraulic station, a transverse moving trolley, a wire feeding device, a testing rack, a mechanical pay-off rack and a test board valve group, the test rack comprises a test board front rack and a test board rear rack; and the mechanical pay-off rack is fixed on the rear rack of the test bench. The device has the advantages that the visual field is wider during debugging and maintenance, the device is safer compared with testing on the bundling machine, and potential safety hazards existing during testing on the bundling machine are greatly reduced. Due to the fact that the annular closed type bearing guide groove is arranged, the winding length of the bundling wire in the guide groove by one circle is much shorter than t
