Description
Technical field
The invention belongs to soldering appliance technical field, be specifically related to a kind of high frequency induction welding end protective cover.
Background technique
The soldering tip of existing high-frequency induction brazing, the general copper pipe that adopts makes, copper pipe outer wrap magnetic core, and during work, copper pipe conducts electricity, and the inside of copper pipe leads to cooling water, and copper pipe is fixed by the sealing compound of outside together with magnetic core.The structure of high-frequency induction soldering tip is open in Chinese patent application CN102962577A, CN102974935A.High-frequency induction brazing in use, soldering tip constantly with pipeline friction to be welded, in addition because the temperature of soldered pipeline can reach 800 DEG C, and sealing compound only can resistance to 400 DEG C of high temperature, and after the time is permanent, sealing compound weares and teares, and exposes copper pipe.And after copper pipe exposes, contact with refrigeration pipe (copper pipe or iron pipe), the cooled pipeline short circuit of soldering tip, owing to copper pipe there being electric current pass through, cause soldering tip to be struck sparks, time serious, injure personal safety.After copper pipe spills, then through wearing and tearing after a while, probably worn out, cause internal cooling water to be revealed, soldering tip cannot use.Therefore, the mode adopting sealing compound to protect soldering tip in prior art only can prevent soldering tip from wearing and tearing in a short time, reduces the working life of soldering tip.
Summary of the invention
Based on above background, the present invention is intended to the sealing compound and the copper pipe serious wear that solve soldering tip, affects the problem in soldering tip working life.
The present invention is achieved by the following technical solutions:
A kind of assembly method of high frequency induction welding end protective cover, step is as follows: first load in sheath by the inductor plush copper of soldering tip, measure the relative position of sheath and inductor plush copper, sheath and inductor plush copper, magnetic core are first fixed with common glue, then sealing compound is poured in sheath, after adhesive curing.
The sheath batch that batch standardization can be prepared by the method is assemblied on soldering tip, and sealing compound used has mobility under normal temperature and higher temperature, and convenient cast, after cast, namely solidifiable is fixed at normal temperatures, and therefore the method has advantage simply and easily.
Further, described sheath adopts wear-resisting, high temperature resistant material; Preferably ceramic; Further preferential oxidation aluminium pottery.
Aluminium oxide ceramics has good conductivity, mechanical strength and heat-resisting quantity.Its Rockwell hardness is HRA80-90, is only second to diamond, considerably beyond Wear Resisting Steel and stainless wear-resisting property.Its wear resistance is equivalent to 266 times of manganese steel, 171.5 times of rich chromium cast iron.Its density is 3.5g/cm
3, be only the half of iron and steel, greatly can alleviate machine utilization.Its compressive strength >=850MPa, resistance to flexure >=290MPa, thermal conductivity 20W/m.K.
Further, the thickness of described sheath is 0.8-1.5mm, under proof strength and the prerequisite in working life, have selected the thinnest size, can save material on the one hand, can ensure that the volume of soldering tip is minimum on the other hand, facilitate welding operation.
Further, described common glue is 502 glue.
Further, described sealing compound is heatproof more than 400 DEG C, and thermal conductivity is greater than the sealing compound of 0.2W/ (mK).
Further, the addition of described sealing compound is flush with the opening edge of sheath, inductor plush copper all can be embedded in wherein, ensure its insulation effect.
Further, the quantity of described sheath is two, is enclosed within respectively in two inductor plush coppers.
Further, the shape of described sheath is the cuboid, cylindrical body, semicylinder etc. of an opening, for saving material, control the considerations such as weld head size, the sheath of suitable shape can be selected according to the shape of inductor plush copper, and need not be confined to the above-mentioned shape enumerated.
Further, the face that two sheaths are relative is plane, easy to use like this, and can standardization make.
Further, be provided with positioning block between two sheaths, positioning block is fixed on soldering tip support, and positioning block, for welding location, makes the heating location of soldering tip be fixed on solder joint.
Further, the side of two sheaths is provided with stiffening plate, and stiffening plate is fixedly connected with soldering tip support.Stiffening plate can prevent soldering tip deformation of timbering on the one hand, can reinforce shape and the position of sheath on the other hand.
Further, the space between described inductor plush copper and sheath is filled by sealing compound, can increase the soundness that sheath is combined with inductor on the one hand, on the other hand because sealing compound is that flexible material can play certain buffer function.
Further, described sheath arranges position structure, can position by the pipeline special to some structures.
Further, described position structure is positioned at the one end away from soldering tip support on the relative face of two sheaths, and this position structure can position pipe under filter.
The assembly method of sheath of the present invention develops specially according to the special shape of inductor and the unique design of sheath, inventor had once attempted pouring into other the multiple method beyond sealing compound, all cannot to reach that the present invention is simple and convenient, effect that batch Standardization Process, fixation, insulating properties are good.By increasing sheath in inductor outside, considerably increase the working life of soldering tip, do not add sheath in prior art, the working life of soldering tip is only 200,000 times, and after increasing sheath of the present invention, the life-span of soldering tip reaches more than 1,000,000 times.In addition, sheath is made by die sinking, and the size of every sheath is all standard, and has the soldering tip matched with it to make frock, the therefore making of soldering tip standardization more.
