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 component manufacturing technology field, especially relevant with a kind of stainless steel baffler and manufacturing process thereof.
Background technique
Baffler be use in a kind of refrigeration system not only can make air communication cross but also can effectively reduce the equipment of noise, it comprises the bigger hush pipe of one section diameter and is welded in hush pipe two ends diameter less suction tude and steam outlet pipe.The hush pipe of conventional muffler, suction tude and steam outlet pipe all are to adopt copper pipe to process, and the copper product price is high, makes the baffler cost than higher; The baffler that uses irony hush pipe and copper turnover tracheae to be welded into has appearred on the market; Through ferrous material Alloy instead of Copper material, practiced thrift cost, but the hush pipe outer wall of irony needs the rust prevention by applying liquid material layer; The resin layer material generally is rust proof paint or rust proof 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
The object of the invention is exactly to overcome the defective of existing refrigeration system with baffler cost height or get rusty easily corrosion and the easy befouling 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 adopts following technological scheme:
The stainless steel baffler; Comprise hush pipe and the suction tude, the steam outlet pipe that are welded in the hush pipe two ends, the hush pipe diameter is greater than suction tude and steam outlet pipe, and steam outlet pipe stretches into the hush pipe inner chamber; Suction tude and steam outlet pipe are copper pipe, it is characterized in that: described hush pipe material is a stainless steel.
The manufacturing process of stainless steel baffler may further comprise the steps: the first step, 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; Use spinning machine that reducing is carried out at the Stainless Steel Tube two ends then, process weld port, last cleaning, drying at the Stainless Steel Tube two ends; Second step, suction tude and steam outlet pipe preparation, the copper pipe that intercepting is fit to length to the copper pipe chamfering, uses flaring machine that copper pipe one end is carried out enlarging as requested then, and the copper pipe flared end is used for being connected with refrigeration system pipeline, carries out cleaning, drying at last; It is characterized in that: in described second step; Copper pipe is carried out enlarging processing back on the sidewall of the welding position of copper pipe, get the salient point toward evagination from interior; The 3rd step of described manufacturing process is assembling; Suction tude and steam outlet pipe are inserted the weld port of hush pipe respectively, and the salient point through the welding position supports suction tude and steam outlet pipe and hush pipe is interfixed, and then solid-state spelter bronze is filled into weld seam; The 4th step, welding, through brazier, the brazier temperature is controlled between 900 ℃～1065 ℃ with the baffler to be welded that assembles, and the speed through brazier is at 0.25～0.7 meter/minute; The 5th step, the check of leaking hunting.
The present invention replaces with Stainless Steel Tube through using the hush pipe material with baffler, can reach following beneficial effect: reduced antirust spraying treatmen, improved the feature of environmental protection, practiced thrift cost, avoided getting rusty of baffler, prolonged working life.
Description of drawings
Fig. 1 is a section of structure of the present invention.
Embodiment
Be described in detail below in conjunction with the accompanying drawing specific embodiments of the invention.
As shown in Figure 1; Stainless steel baffler of the present invention comprises hush pipe 2 and the suction tude 3, the steam outlet pipe 1 that are welded in hush pipe 2 two ends, and hush pipe 2 diameters are greater than suction tude 3 and steam outlet pipe 1, and steam outlet pipe 1 stretches into hush pipe 2 inner chambers; Suction tude 3 is a copper pipe with steam outlet pipe 1, and hush pipe 2 materials are stainless steel.The manufacturing process of this stainless steel baffler may further comprise the steps: the first step, 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, use spinning machine that reducing is carried out at the Stainless Steel Tube two ends then; Process weld port at the Stainless Steel Tube two ends, last cleaning, drying; Second step; Suction tude and steam outlet pipe preparation, intercepting is fit to the copper pipe of length, to the copper pipe chamfering; Use flaring machine that copper pipe one end is carried out enlarging as requested then; The copper pipe flared end is used for being connected with refrigeration system pipeline, copper pipe is carried out enlarging processing back on the sidewall of the welding position of copper pipe, get the salient point toward evagination from interior, carries out cleaning, drying at last; In the 3rd step, assembling is inserted the weld port of hush pipe respectively with suction tude and steam outlet pipe, and the salient point support through the welding position interfixes suction tude and steam outlet pipe and hush pipe, then solid-state spelter bronze is filled into weld seam; The 4th step, welding, through brazier, the brazier temperature is controlled between 900 ℃～1065 ℃ with the baffler to be welded that assembles, and the speed through brazier is at 0.25～0.7 meter/minute; In the 5th step, the check of leaking hunting checks whether product has failure welding.
