Abstract
The invention discloses a stainless steel muffler and a manufacturing process thereof, and belongs to the technical field of manufacturing refrigeration system components. The current muffler used by a refrigeration system is high in cost or easily pollutes the environment and is corroded by rusting. The stainless steel muffler consists of a stainless steel hush pipe and a copper air inlet pipe and a copper air outlet pipe welded at two ends of the hush pipe, and the manufacturing method for the stainless steel muffler comprises the following steps of: 1, preparing the hush pipe by using a stainless steel pipe; 2, preparing the air inlet pipe and the air outlet pipe by using copper pipes, and beating the side walls at welding positions of the copper pipes to form salient points which protrude from inside to outside; 3, assembling, namely inserting the air inlet pipe and the air outlet pipe into welding ports at two ends of the hush pipe respectively, fixing the air inlet pipe and the air outlet pipe, and filling a solid bronze solder into welding seams; 4, welding, namely passing the assembled muffler to be welded through a welding furnace, and controlling the temperature of the welding furnace to be between 900 and 1,065 DEG C and the passing speed to be between 0.25 to 0.7 meter/minute; and 5, performing leak checking. By the stainless steel muffler, an anti-rust spraying treatment is not needed, and the rusting of the muffler is avoided.
Description
Technical field
The invention belongs to refrigeration system parts manufacturing technology field, especially relevant with a kind of stainless steel muffler and manufacturing process thereof.
Background technology
Muffler is not only air-flow being passed through but also effectively reducing the equipment of noise of using in a kind of refrigeration system, and it comprises the hush pipe that one section diameter is larger and is welded in hush pipe two ends diameter less air inlet pipe and escape pipe.The hush pipe of conventional muffler, air inlet pipe and escape pipe all are to adopt copper pipe to make, and the copper product price is high, so that the muffler cost compare is high; The muffler that uses irony hush pipe and copper turnover tracheae to be welded into has appearred on the market, replace copper material by ferrous material, saved cost, but the hush pipe outer wall of irony needs the rust prevention by applying liquid material layer, the antirust coat material generally is antirust paint or antirusting paint, these materials cause environmental pollution easily in spraying process, and the hush pipe inwall is rust prevention by applying liquid material layer not, and still get rusty easily corrosion.
Summary of the invention
Purpose of the present invention is exactly will overcome existing refrigeration system with the defective of muffler cost height or get rusty easily corrosion and the easy contaminated environment of its manufacture process, provides a kind of and can not get rusty and lower-cost refrigeration system pipeline spare and manufacturing process thereof.For this reason, the present invention is by the following technical solutions:
The stainless steel muffler, comprise hush pipe and the air inlet pipe, the escape pipe that are welded in the hush pipe two ends, the hush pipe diameter is greater than air inlet pipe and escape pipe, and escape pipe stretches into the hush pipe inner chamber, air inlet pipe and escape pipe are copper pipe, it is characterized in that: described hush pipe material is stainless steel.
The manufacturing process of stainless steel muffler, may further comprise the steps: the first step, the hush pipe preparation, the stainless steel tube of intercepting appropriate length to stainless steel tube two chamfers, carries out annealing in process to stainless steel tube after the chamfering, reduce steel pipe hardness, then use spinning machine that reducing is carried out at the stainless steel tube two ends, make weld port at the stainless steel tube two ends, last cleaning, drying; Second step, air inlet pipe and escape pipe preparation, the copper pipe that intercepting is fit to length to the copper pipe chamfering, then uses pipe-expanding machine that copper pipe one end is carried out enlarging as requested, and the copper pipe flared end is used for being connected with refrigeration system pipeline, carries out at last cleaning, drying; It is characterized in that: in the described second step, copper pipe is carried out getting from the salient point of interior past evagination at the welding position of copper pipe sidewall behind the expanding, the 3rd step of described manufacturing process is assembling, air inlet pipe and escape pipe are inserted respectively the weld port of hush pipe, salient point support by the welding position interfixes air inlet pipe and escape pipe and hush pipe, then solid-state spelter bronze is filled into weld seam; The 4th step, welding, by brazier, the brazier temperature is controlled between 900 ℃～1065 ℃ with the muffler to be welded that assembles, and the speed by brazier is at 0.25～0.7 m/min; The 5th step, the check of leaking hunting.
The present invention can reach following beneficial effect: reduced antirust spray treatment, improved the feature of environmental protection, saved cost, avoided getting rusty of muffler, prolonged service life by using the hush pipe material with muffler to replace with stainless steel tube.
Description of drawings
Fig. 1 is section of structure of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
As shown in Figure 1, stainless steel muffler of the present invention comprises hush pipe 2 and the air inlet pipe 3, the escape pipe 1 that are welded in hush pipe 2 two ends, and hush pipe 2 diameters are greater than air inlet pipe 3 and escape pipe 1, and escape pipe 1 stretches into hush pipe 2 inner chambers, air inlet pipe 3 and escape pipe 1 are copper pipe, and hush pipe 2 materials are stainless steel.The manufacturing process of this stainless steel muffler may further comprise the steps: the first step, the hush pipe preparation, the stainless steel tube of intercepting appropriate length, to stainless steel tube two chamfers, after the chamfering stainless steel tube is carried out annealing in process, reduce steel pipe hardness, then use spinning machine that reducing is carried out at the stainless steel tube two ends, make weld port at the stainless steel tube two ends, last cleaning, drying; Second step, air inlet pipe and escape pipe preparation, intercepting is fit to the copper pipe of length, to the copper pipe chamfering, then use pipe-expanding machine that copper pipe one end is carried out enlarging as requested, the copper pipe flared end is used for being connected with refrigeration system pipeline, and copper pipe is carried out getting from the salient point of interior past evagination at the welding position of copper pipe sidewall behind the expanding, carries out at last cleaning, drying; In the 3rd step, assembling is inserted respectively the weld port of hush pipe with air inlet pipe and escape pipe, and the salient point by the welding position supports air inlet pipe and escape pipe and hush pipe are interfixed, and then solid-state spelter bronze is filled into weld seam; The 4th step, welding, by brazier, the brazier temperature is controlled between 900 ℃～1065 ℃ with the muffler to be welded that assembles, and the speed by brazier is at 0.25～0.7 m/min; In the 5th step, the check of leaking hunting checks whether product has failure welding.
