Description
Technical field
The invention belongs to heat-exchange apparatus, relate to a kind of for the oil cooled strong oil-water refrigerating mechanism of transformator.
Background technology
Spiral plate type cooler is a kind of novel application heat-exchange apparatus the most widely, and it has heat transfer effect height, resistance
The series of advantages such as power loss is little, stable operation reliable, compact conformation, low price.Have been widely used at present in petrochemical industry
The industrial departments such as refrigeration, organic chemical industry's food, dyestuff alkaline pharmacy, machinery, metallurgy, are domestic initiations as transformer cooler
Existing recent two decades history, effect is favourable.
Spiral plate oil water cooler is to be 2-3mm by two thickness, and roll bending rolls into Shang Ge road, two uniform directions
Spirillum.A kind of thermophore (You Heshui) is had to carry out heat exchange in full reverse flow state in two passages respectively.Its film-cooled heat
It is that the expansion length of two steel plates is multiplied by steel plate width sum.In order to strengthen the rigidity of steel plate, improve spirochetal critical pressure, at two
Steel plate same is welded with the spacing column of certain density on practising physiognomy, and the most also can increase the disturbance of fluid, increase Reynolds number, carries
High heat transfer efficiency.Spiral plate type cooler of transformer cylinder by two steel plates same practise physiognomy on be welded with certain density
The roll bending of spacing column, the steel plate end outermost one layer longitudinally carries out welding and forms a cylindrical structural.Then roll bending is rolled up
The steel plate both sides making two passages carry out welded closure with round steel respectively.When carrying out welded closure with round steel, due to round steel
Hardness is high, first round steel to be rolled into the shape of helical duct, and in the steel plate both sides of passage to be inserted, then carries out seal weld
Connect, complete the processing of spiral plate type cooler of transformer cylinder.It needs many people to coordinate, the most time-consuming, complex process,
Operation is many, and operative employee's workload is big.It addition, round steel be rolled into helical duct insert passage time, it may appear that round steel eject phenomenon,
There is certain potential safety hazard.When two-layered steel plates rolls, insert passage, therefore owing to round steel to be considered is rolled into helical duct
The gap that its two-layered steel plates rolls can be bigger than normal, and the welding rod of needs is many.When operation, need related tool to coordinate, spiral shell easily occurs
The steel plate both sides deformation of rotation passage, affects welding quality.
Summary of the invention
The invention aims to solve above-mentioned the deficiencies in the prior art, it is provided that a kind of transformator spiral plate type cools down
The manufacture method of device cylinder, round steel rolls with steel plate simultaneously, with Simplified flowsheet, operates safety, reduces operative employee, improves and produce effect
Rate and product quality.
Present invention solves the technical problem that and be the technical scheme is that
The manufacture method of a kind of spiral plate type cooler of transformer cylinder, its cylinder includes that the same of two-layered steel plates is practised physiognomy
On be welded with the roll bending of spacing column, two-layered steel plates roll two passages of formation, the steel plate both sides of two passages use round steel respectively
Carrying out welded closure, two-layered steel plates is rolled by veneer reeling machine, it is characterized in that two-layered steel plates when veneer reeling machine rolls, on
Stating round steel and be positioned at the steel plate both sides of two passages, above-mentioned round steel rolls with two-layered steel plates simultaneously, forms a cylindrical tube knot
Structure, then carries out welded closure to the round steel of the steel plate both sides of two passages.
State round steel due to employing to roll with two-layered steel plates simultaneously, form a cylindrical tube structure, decrease a round steel
Volume inserts operative employee in the steel plate both sides of passage, does not have original potential safety hazard.Tong Bu roll bending is passed through due to round steel and steel plate
Machine rolls, and its concordance is good, and the steel plate both sides of helical duct do not have metaboly；Round steel is tightly combined with steel plate, weld seam
Little, save welding cost, improve welding quality, improve good looking appearance degree simultaneously.Which reduce manpower, simplify technique,
Substantially increase production efficiency.
When being embodied as, it has the following steps:
1) preparing a steel plate, steel plate divides three parts, and before and after steel plate, part is respectively prepass district and rear channel region, in
Portion is flex area, and the upper one side of the steel plate in prepass district is welded with spacing column, and the lower one side of the steel plate of rear channel region is welded with fixed
Away from post, the top and bottom of the flex area at middle part are planar structure;
2) preparing four round steel, four round steel length are suitable with the length of the steel plate left and right sides in antero-posterior pathway district respectively；
3) ready steel plate being installed on veneer reeling machine, the winding up roller of veneer reeling machine is two the semicircle windings up roller cooperated,
The flex area of steel plate is between two semicircle windings up roller, and two semicircle windings up roller clamp the flex area of steel plate；The steel of rear channel region
Plate walk around the semicircle winding up roller forward passage district of upper part steel plate fold, formed above-mentioned same practise physiognomy on be welded with the two of spacing column
Layer steel plate；
4) head of ready four round steel is welded to the steel plate of prepass district and rear channel region both sides roll
Initiating terminal；
5) veneer reeling machine is started working, and round steel rolls with two-layered steel plates simultaneously, forms a cylindrical tube structure；
6) the steel plate end outermost one layer is fixed welding with adjacent steel plate, to ensure that the cylinder rolled unloads
Will not eject after lower veneer reeling machine；
7) the cylinder rolled, take out from veneer reeling machine；
8) weld being located between the round steel of passage and steel plate to carry out sealing, i.e. complete spiral plate type cooler of transformer
The processing of cylinder.
The present invention use two same practise physiognomy on be welded with the steel plate of spacing column and just round steel be placed on steel plate before roll bending
Dual-side, when steel plate is after veneer reeling machine roll bending completes, and round steel is located in roll bending and rolls into the steel plate both sides of two passages, the most not
As prior art employing is manually rolled into round steel the shape of helical duct, then inserts in the steel plate both sides of passage, which reduce
Manpower, simplifies technique, substantially increases production efficiency.Rolled by veneer reeling machine owing to round steel is Tong Bu with steel plate, its concordance
Good, the steel plate both sides of helical duct do not have metaboly, improve welding quality, improve good looking appearance degree simultaneously.
When being embodied as, two sides of the feed end of veneer reeling machine are provided with backer, on same for the two-layer overlaped practising physiognomy
Being welded with the steel plate of spacing column and put into veneer reeling machine when rolling, the both sides end face of two-layered steel plates is attached on backer, veneer reeling machine work
Make, two steel plates are carried out roll bending, backer ensure its side round steel will not sideslip, can be successfully between two steel plates
On passage.
When being embodied as, above-mentioned backer is provided with roller, and roller withstands on the both sides of two-layered steel plates.
The invention has the beneficial effects as follows: the present invention uses that round steel is Tong Bu with steel plate to be rolled by veneer reeling machine, and its concordance is good,
The steel plate both sides of helical duct do not have metaboly, improve welding quality, improve good looking appearance degree simultaneously；The biggest
Decrease greatly artificial, improve security performance, improve production efficiency and product quality, reduce product cost.
