Plastic welding machine for oil-gas separator, and plastic welding method

Abstract

The invention relates to a plastic welding machine for an oil-gas separator, and a plastic welding method. The plastic welding machine comprises a base, a top plate and a working cavity, wherein a driving device is arranged on the top plate, and a lower die is arranged on the base; a lower die cavity and a groove are formed in the lower die, and a copper pipe is arranged in the groove, and externally connected with variable high-frequency currents; a movable plate is arranged in the working cavity, and an upper die is arranged on the movable plate; an upper die cavity is arranged on the upper die, and the driving device is connected with the movable plate; the copper pipe is powered on to generate eddy current so that a closed iron wire ring is heated, and a welding wire, located around a second groove, on the lower body of the oil-gas separator is melted; the lower body of the oil-gas separator and the upper body of the oil-gas separator are welded into a whole; and therefore, the technical problems that in the prior art, after the oil-gas separator is welded, welding edges are liable to reserve on the outer surface, and consequently the attractiveness is affected, even the quality is affected due to insecure welding caused by uneven heating are solved.

Description

technical field [0001] The invention relates to the technical field of oil-gas separator welding, in particular to a plastic welding machine and a plastic welding method for an oil-gas separator. Background technique [0002] The oil-air separator is a very important part of the automobile engine, which can maintain the good lubricating performance of the engine oil and prolong the service life of the engine oil. When the engine is working, part of the high-temperature and high-pressure gas leaks into the crankcase through the piston ring. After the diesel steam and water vapor condense, the engine oil will become thinner, the performance will deteriorate, and foam will be formed in the engine oil to destroy the normal supply of the engine oil. This phenomenon is especially serious when the machine is cold in winter. After installing the oil-gas separator, the above-mentioned substances can be separated in time. The upper body and the lower body often need to be welded tog...
