The utility model discloses a wire rod is skinned according to connecing device among the wire rod peeling equipment, including installing in the down coupling part of the piston rod link of air cylinder and edge coupling part's the axially extended part of pressing down, coupling part's outline shape is cylindricly, press partial outline shape be cylindric, press the part with the same axle center of coupling part sets up to and press part and coupling part and be elastic rubber body spare. The utility model provides a wire rod peeling equipment skin to the wire rod that the in -process wire rod is flattened and the damaged problem of external insulation skin to, structure, the cost is reduced have been simplified for technique in the past. Simultaneously for solution wire rod location is bad, the wire rod is draged and leak the problem of skinning, does benefit to the neat pleasing to the eye purpose of shelling the cortex position and reaching. The utility model discloses can also metal product, can be applied to in the ultrasonic machine type for to the processing of skinning of the wire rod of mineral insulation skin, application scope is wide.
