Description
Technical field
The present invention relates to steel cylinder manufacturing technology field, especially a kind of cylinder liner manufacture craft.
Background technique
Cylinder liner is the container for the liquid such as cryopreservation or transporting liquid nitrogen or gas, usually selection stainless steel
Matter.It is segmental machining welding to the manufacturing process of stainless steel inner container now, since weld seam is more, is constantly in use super
Under low-temperature condition, weld metal is easy to appear change in toughness, and then the generation of brittle fracture accident occurs.
Summary of the invention
For the deficiency in background technique, the present invention provides a kind of cylinder liner manufacture craft, and overcomes above lack
It falls into.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of cylinder liner manufacture craft, cylinder liner include body and end socket, comprising the following steps:
Selection: it selects stainless steel plate as embryo material, is cut into the stainless steel circle of corresponding size for cutting machine according to liner size
Plate；
Polishing: the cutting edge of stainless steel plate is polished, and sanding burr is removed, Thickness sensitivity；
Cover half: drawing die, the mould that there are mold at least four depth successively to deepen are selected according to stainless steel plate size
Has position, and mold is fixed on clapper die spotting press, shows to clean to mold using preceding；
It stretches: stainless steel plate is placed between upper and lower mould, and plectane center and plunger tip center are on the same line, pass through plunger tip
First time stretching is carried out to stainless steel plate, annealing carries out second and stretches, and annealing, third time stretches, annealing, the 4th drawing
It stretches, anneals, shaping is completed；
Port cutting: the semi-finished product liner port end for stretching completion carries out trimming polishing；
Close up: by stretch complete semi-finished product liner 1000-1100 DEG C at a temperature of, squeeze to form end socket by hot spinning,
It is cooling；
Cleaning: clear water injects interior gallbladder intracavity, keeps 10-15min, discharge.
Wherein in annealing steps, the stainless steel plate after each stretch is placed in de- stove and is made annealing treatment, is annealed
Furnace temperature is kept for 950-1000 DEG C, then duration 15-20min carries out rapid cooling.
It stretches every time and completes to be observed the tensional state of part, if there is fold or the stopping of obvious thickness difference are next
Secondary stretching, first repairing treatment.
Tensile speed 50-70mm/min in the stretching step.
Cylinder liner entire length 400-2200mm after molding, body trans D 200-1000mm, body side thickness
1.5-4.5mm
By adopting the above-described technical solution, effectively improving existing liner influences asking for service life by welding production
Topic, the liner welding gap which goes out, liner are completed by stretching, the labor of manufacture craft
Dynamic cost reduces, and efficiency improves, and improves the service life and safety in utilization of product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the made product of invention.
1, body in figure；2, end socket.
Specific embodiment
With reference to Fig. 1 it is found that the present invention: a kind of cylinder liner manufacture craft, cylinder liner include body 1 and end socket 2, including
Following steps:
Selection: it selects stainless steel plate as embryo material, is cut into the stainless steel circle of corresponding size for cutting machine according to liner size
Plate；
Polishing: stainless steel plate surface is polished, and sanding burr is removed, Thickness sensitivity；
Cover half: drawing die, the mould that there are mold at least four depth successively to deepen are selected according to stainless steel plate size
Has position, and mold is fixed on clapper die spotting press, shows to clean to mold using preceding；
It stretches: stainless steel plate is placed between upper and lower mould, and plectane center and plunger tip center are on the same line, pass through plunger tip
First time stretching is carried out to stainless steel plate, annealing carries out second and stretches, and annealing, third time stretches, annealing, the 4th drawing
It stretches, anneals, shaping is completed；
Close up: by stretch complete semi-finished product liner 1000-1100 DEG C at a temperature of, squeeze to form end socket by hot spinning,
It is cooling；Preferably, optimum stretch temperature is 950 DEG C.
Cleaning: clear water injects interior gallbladder intracavity, keeps 10-15min, discharge.
Wherein in annealing steps, the stainless steel plate after each stretch is placed in de- stove and is made annealing treatment, is annealed
Furnace temperature is kept for 950-1000 DEG C, then duration 15-20min carries out rapid cooling.
It stretches every time and completes to be observed the tensional state of part, if there is fold or the stopping of obvious thickness difference are next
Secondary stretching, first repairing treatment.
Tensile speed 50-70mm/min in the stretching step.
Spray treatment is carried out to the liner surface that cleaning finishes as needed.
Cylinder liner entire length 400-2200mm after molding, body trans D 200-1000mm, body side thickness
1.5-4.5mm。
The present invention effectively improves the problem of existing liner influences service life by welding production, the cylinder liner
The liner welding gap that manufacture craft structure fabrication goes out, liner are completed by stretching, and the labour cost of manufacture craft reduces, effect
Rate improves, and improves the service life and safety in utilization of product.
Every technical staff's notice: of the invention although the present invention is described according to above-mentioned specific embodiment
Invention thought be not limited in the invention, any repacking with inventive concept will all be included in this patent protection of the patent right
In range.
