Description
Technical field
The present invention relates to a kind of end socket pressing process, especially a kind of high strength titanium alloy end socket pressing process.
Background technique
Titanium attaches great importance to it as a kind of outstanding Marine Materials, various countries' shipbuilding industry, successively has developed the ship of series
Use titanium alloy.Titanium alloy has low strength alloys, moderate strength alloy and a high strength alloys according to intensity classification, titanium alloy by
Strongest specific strength and excellent corrosion resistance in metal material, loss of weight is obvious, improves the reliability, resistance to of equipment
The advantages that long property, has a wide range of applications in shipbuilding industry.
Due to the performance that there is titanium many to be adapted as briny environment material, such as anti-spot corrosion and cracking corrosion resist and answer
Power burn into electrochemically resistant corrodes and has higher yield strength and tensile strength etc., therefore, the heat exchange in marine environment
Device, condenser, cooler and pipeline select titanium substitution corronil to have become a main trend.With in the past use corronil phase
Than, titanium physical property, mechanical property and in terms of there is apparent advantage, and can also be saved in terms of maintenance
It makes an appointment and expense.
Titanium condenser is mainly made of seawater inlet and outlet end cap, shell, pipe group and attachment etc., end cap by end socket and flange and
Inlet and outlet adapter tube is welded, and wherein the shape of end socket is elliposoidal.Its purposes be with seawater cooling steam or hot water, steam or
Person's hot water walks shell-side, enters in shell-side from the entrance sleeve of shell-side, and fills after part contacts along circuit and the heat exchanger tube that partition is formed
Heat exchange is carried out, is discharged by discharge connection.Seawater walks pipe side, enters water chamber by the entrance sleeve of end cap, through heat exchanger tube,
Reflux end cap is made to be discharged after flowing back several times through end cap discharge connection.Seawater is set constantly to take away the heat of steam or hot water in this way
Amount, so that steam or hot water be made to be cooled to the temperature of needs.
Underwater titanium condenser, seawater design pressure reach 3Mpa, and end cap flange and end socket are not suitable for using low and medium
Strength titanium alloys, flange must be manufactured with high strength titanium alloys, and end socket must suppress due to titanium with high strength titanium alloys
Itself the characteristics of, in addition intensity is high, temperature drop is big, and cooling velocity is very fast under external environment, and inhomogeneous cooling is even, and resistance of deformation is big,
End socket is easy to crack when suppressing, and the country breaks through the technology not yet at present.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of high strength titanium alloy end socket pressing process, improve titanium alloy
End socket yield rate.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
A kind of high strength titanium alloy end socket pressing process, it is characterised in that comprise the steps of:
Step 1: prepare titanium head plate blank；
Step 2: manufacture craft plate；
Step 3: production test plate (panel)；
Step 4: test plate (panel) is heated, and precompressed is then carried out on press die；
Step 5: titanium head plate blank and board are subjected to end socket compacting together.
Further, the step 1 is specially that titanium head plate is processed into circular blank, then by the side of circular blank
Edge processing is in the arc-shaped to reduce stress concentration, prevents from cracking in pressing process.
Further, the step 2 is specially and is processed into the carbon steel sheet of 6-16mm thickness and titanium head plate blank shape
Matched circle board.
Further, the step 3 is specially and is processed into the carbon steel sheet of 10-20mm thickness to match with titanium head plate blank
Round test plate (panel).
Further, the step 4 is specially and the test plate (panel) processed is put into furnace to heat, then will be heated
Test plate (panel), which is placed on press die, carries out precompressed, to preheat to press die.
Further, the test plate (panel), which is put into furnace, is heated to 800-900 DEG C.
Further, the step 5 is specially and ready board is placed on press die, while titanium being sealed
Head plate blank, which is placed into furnace, to be heated, and is then taken out titanium head plate blank out of furnace rapidly and is placed on the upside of board,
Press is opened quickly to be suppressed by mold.
Further, the titanium head plate blank is heated to 800-900 DEG C in furnace.
Further, step 1 is completed within 3 minutes to step 5 whole process.
Further, when in-furnace temperature is down to 350-450 DEG C, end socket and board that compacting is completed are put into togerther furnace
It is interior, furnace cooling.
Compared with prior art, the present invention having the following advantages that and effect: process flow of the invention is simple, improves titanium
The product qualified rate of alloy end enclosure, the titanium alloy closing end any surface finish suppressed are not local, without departing from its thickness deviation
The defects of crackle, scuffing, impression, pit, the ultrasonic examination for carrying out area 100% are examined, and the regulation of GB5193 is met.
Specific embodiment
Below by embodiment, the present invention is described in further detail, following embodiment be explanation of the invention and
The invention is not limited to following embodiments.
A kind of high strength titanium alloy end socket pressing process of the invention comprising the steps of:
Step 1: prepare titanium head plate blank；Titanium head plate is processed into circular blank, then processes the edge of circular blank
It is in the arc-shaped to be concentrated with reducing stress, it prevents from cracking in pressing process.
Step 2: manufacture craft plate；The carbon steel sheet of 6-16mm thickness is processed into matched with titanium head plate blank shape
Round board reduces the deformation of titanium end socket to suppress together with titanium end socket.
Step 3: production test plate (panel)；The carbon steel sheet of 10-20mm thickness is processed into and the matched round examination of titanium head plate blank
Plate.
Step 4: test plate (panel) is heated, and precompressed is then carried out on press die；The test plate (panel) processed is put into furnace and is added
