The invention relates to an
alloy pipe surface corrosion prevention device with a good effect. The device comprises a base, a supporting rod, a clamping mechanism, a uniform smearing mechanism, an opening mechanism and a
corrosion prevention mechanism; and the uniform smearing mechanism and the
corrosion prevention mechanism are both arranged on the base. According to the
alloy pipe surface corrosion prevention device with the good effect, clamping of a workpiece is achieved through the clamping mechanism,
corrosion prevention of the workpiece is achieved through the
corrosion prevention mechanism, uniform smearing of a
preservative is achieved through the uniform smearing mechanism to achieve a better
corrosion prevention effect, and operation of the clamping mechanism and the uniform smearing mechanism is limited through the opening mechanism; compared with an existing opening mechanism, the opening mechanism of the device can be started through treading, manpower is saved, a pure mechanical structure is adopted, and the practicability is high; compared with an existing uniform smearing mechanism, the uniform smearing mechanism of the device not only achieves uniform smearing ofthe
preservative, but also achieves auxiliary clamping of the workpiece; and compared with an existing clamping mechanism, the clamping mechanism of the device adopts flexible clamping, so that the situation that the surface of the workpiece is scratched due to rigid clamping is avoided, and the workpiece is protected.
