step A3, comparing actual pressure drop Δ P of the hose with theoretical pressure drop Δ P0When the magnitude of (1) is Δ P- Δ P0When the pressure is higher than A, wherein A is a preset pressure drop error, which shows that the actual pressure drop of the hose is far larger than the theoretical pressure drop, namely the hose is not smooth and is blocked, the indicator light is turned on, and when delta P-delta P is reached0When A is less than or equal to A, the actual pressure drop of the hose is close to the theoretical pressure drop, namely the hose is unobstructed, and the indicator lamp is turned off.
10. The automatic hose cutting and chamfering machine according to claim 3, further comprising: the hose previewing device is connected to the rack (1) and used for detecting the diameter and the quality of the hose to be processed, the hose previewing device is electrically connected with the controller, the controller predicts the deformation of the hose according to a preset algorithm, and the hose previewing device comprises the following steps:
step A1, obtaining the curvature radius R of the hose through the detection of a hose pre-detection device1And a gravity G;
step A2, calculating the deformation delta of the hose when the first electric clamping jaw (34) clamps the hose as follows:
