The specific embodiment
Reaching specific embodiment in conjunction with the accompanying drawings is further described the present invention.
The welding procedure of a kind of cylindrical shell (or staving) and air copper tube, cylindrical shell (or staving) is the cylindrical shell (or staving) of electric equipment, air copper tube can be that air intake duct also can be a blast pipe, need to prove, a kind of cylindrical shell of the present invention (or staving) not only is only limited in various air intake ducts, blast pipe with the welding procedure of air copper tube, can also be various water service pipes or fluid-through tube etc., so long as the welding of cylindrical shell (or staving) and metal copper pipe all is the range of application of the welding procedure of a kind of cylindrical shell of the present invention (or staving) and air copper tube.
With the compressor of air conditioner is example, introduces the welding procedure of a kind of cylindrical shell of the present invention (or staving) and air copper tube.
As shown in Figure 1, the welding procedure of a kind of cylindrical shell of the present invention (or staving) and air copper tube comprises two steps, at first blast pipe 2 and steel part 3 welding is formed weld assemblies, then with this weld assembly and cylindrical shell (or staving) welding.Steel part 3 is conical hollow steel part, and steel part 3 a bigger end and blast pipes 2 weld, like this can be so that be convenient to produce when this weld assembly and cylindrical shell (or staving) 1 welding.
The mode of soldering is adopted in blast pipe 2 and the welding of steel part 3, because the welding between blast pipe 2 and the steel part 3, needn't consider to be out of shape the factors such as cleaning with residue, adopts the mode of soldering, and cost is lower, is convenient to the producer and controls cost, the raising market competitiveness.
In the step 2, the welding equipment welding of inversion or energy storage is adopted in the welding of weld assembly and cylindrical shell (or staving) 1.Because it is short that the welding equipment of inversion or energy storage has weld interval, can calculate with millisecond and finish welding, and the welding quality height.Therefore, weld assembly and cylindrical shell (or staving) welding can be finished in several milliseconds time.Because almost be to finish in the scope of Millisecond weld interval, therefore, the weld interval of weld assembly and cylindrical shell (or staving) 1 is very short, can not cause cylindrical shell (or staving) 1 distortion, has effectively overcome the defective that can make cylindrical shell (or staving) 1 distortion in the prior art because weld interval is long.
The present invention carries out owing to the welding procedure with cylindrical shell (or staving) 1 and air copper tube 2 is divided into two steps, by having increased a hollow conical steel part 3, the air copper tube 2 that weld interval is long is arranged on welding in advance under the situation that does not contact cylindrical shell (or staving) 1 with steel part 3, therefore the influence of effectively having avoided this step welding that simplified (or staving) 1 caused, simultaneously this welding side is adopted the more cheap brazing mode of cost, help control and save cost.Again with weld assembly and cylindrical shell (or staving) 1 welding, because this step touches cylindrical shell (or staving) 1, therefore, this step adopts very short inversion or energy storage device welding of weld interval to carry out, weld interval is short, can not cause cylindrical shell (or staving) 1 distortion.In addition, because inversion or energy storage device welding quality height need not increase the residue matting, be convenient to save operation.
For the ease of producing, weld assembly can be prepared in advance, only need during welding this weld assembly and cylindrical shell (or staving) 1 welding are got final product.As shown in Figure 3, a kind of weld assembly that is used for cylindrical shell (or staving) 1 and air copper tube 2 welding, described weld assembly comprises air copper tube 2 and steel part 3, and described air copper tube 2 is weldingly fixed on steel part 3, and described steel part 3 is set to conical hollow steel part.A thicker end and the described air copper tube 2 of steel part 3 weld together, like this can be so that be convenient to processing during this weld assembly and cylindrical shell (or staving) 1 welding.In order to save cost, described weld assembly is the weld assembly that adopts the mode of furnace brazings to be prepared from air copper tube 2 and described steel part 3.With low cost, convenient processing that this weld assembly has can be carried out in automation, is fit to large-scale characteristics of producing.During welding, only need the steel part end and cylindrical shell (or staving) 1 welding of this weld assembly are got final product, easy to use.
Should be noted that at last: above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although detailed explanation has been done in invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the essence and the scope of technical solution of the present invention.
