Description
Technical field
The present invention relates to processing hot-bending bends technical field, be related to a kind of internal diameter precision it is high, with straight pipe and special
Material bend pipe simmers technique processing unit (plant) processed, and in particular to limits cooling device to a kind of hot-bending bends inductor.
Background technology
The industries such as nuclear industry, petrochemical industry, submarine, warship, electric power, natural gas, boiler, it is a large amount of to use the heat for having straight pipe
Simmering and bending pipe carries out conveying liquid, gas, solid particle.All it is heat induced when the hot-bending bends with straight pipe are processed at present
Snare is on steel pipe, and point-blank, cooling water jetting holes are located on induction coil and are formed for heating tape and turntable center setting
40 ° of angles carry out spray cooling to heating red tape.Such cooling means has the following problems：1, the cooling water sprayed necessarily falls,
Still it is water completely although there is lower shutter grate on the ground, other than lower shutter grate, winter is easy to freeze, therefore often someone slips and scalds,
And often there is electric shock accidents.2, spray cooling is carried out to heating red tape due to cooling water, cold and hot exchange will produce a large amount of water
Steam, and on the position alignment induction coil of infrared thermometer heating red tape, cooling water spray site distance heating red tape is insufficient
The distance of 10mm（Distance cools down position beyond 10mm, and the bend pipe ovality for simmering system increases standard not up to standard）Although 40 ° of angle injections
It is cooling, but still there is part cooling water to splash on heating red tape, in addition the vapor of cold and hot exchange so that far infrared temperature measurement instrument institute
Thermometric is inaccurate, measures gained temperature value and performs practically no function.
Based on the reason of above-mentioned 2nd article, it is still the heating grasped by rule of thumb by operating personnel that in fact bend pipe, which simmers process processed,
The temperature of band and the travel speed of push machine carry out.When simmering the bend pipe of special material and special process processed, the straight of bend pipe is needed
Pipeline section and bend pipe are one integral piece product one-time heating moldings in the state of not parking.From straight pipe to the starting point of bend pipe, pass through
The stewing system of bend pipe arrives the terminal of straight pipe again, is to maintain same temperature heating and same speed promotes to complete.Bend pipe pushing
The operation principle of machine is：With two pairs of rollers by steel tube clamping, tube bending jig clamps one end of steel pipe, is equipped at the center of turntable remote red
Induction Heating Coil outside outer temperature measurer, temperature measurer and steel pipe be point-blank, when induction coil is heated to operating temperature,
Plate to be promoted mainly to push ahead the steel pipe other end, the steel pipe being bent drives turntable and tube bending jig to be rotated to the side set,
Heating red tape is exactly the inflection point of bend pipe, can be simmered into the bend pipe that both ends carry straight pipe in this way.But there was only bend pipe in this way
It is the product by heating and cooling injection quenching, and the straight pipe at both ends is still the state of original base material, inflection point and straight section
The junction of base material does not meet technological requirement.Most processing enterprises are all to drive heat induced using induction hardening transformer thus
Circle.In tube bending jig without first driving induction Heating Coil to be pressed from the front end of steel pipe by induction hardening transformer straight pipe before clamping
Pushing process speed and temperature are walked backward, when running to inflection point, are clamped steel pipe with tube bending jig and are started simmering and bending, bend pipe simmers system
Stop to bend pipe push machine when camber terminal.By the temperature and speed for simmering technique processed, induction hardening transformer drive induction Heating Coil to
After walk, until technique need flow development length when stop.The unfortunately bend pipe push machine of the method and heating red tape
Distance is too big, and the center of bend pipe push machine turntable is to keep straight line with induction coil heating red tape.It simmers as stated above
It is formed with the bend pipe of straight section, induction coil heating the distance between red tape and bend pipe push machine have to be larger than the 1.5 of the design of technique straight section
Times.And when simmering general elbow processed, tube bending jig turntable is irremovable again, because of bend pipe push machine and tube bending jig turret base
It is seperated two to receive unit of force greatly, two unit stress degree are consistent, so bend pipe push machine and turret base are required for
Basis is done with concrete.When bending machine need not process special material and special process has straight section bend pipe, turret base is from pushing away
The distance of machine processed is excessive, and generated consequence is that technique pipeline section is long, product virtually increases cost, lacked market competition
Power.
Although induction hardening transformer, which drives induction Heating Coil, is walked backward by pushing process speed, speed can protect
Card, really it cannot be guaranteed that actual temperature.During the prior art simmers bend pipe processed, the ovality of bend pipe bore is unavoidable.Cause
Being induction coil when to simmer bend pipe processed by red tape heating, promoting mainly plate and push ahead, tube bending jig and turntable are with designed radius
Parallel to be rotated to a direction, so the size above and below at steel pipe heating red tape can ensure, and the size of left and right wants small
In upper and lower size.Ball is crossed such as small-bore, minor radius bend pipe and detects that ovality is unqualified to repair, and can only scrap place
Reason.There is presently no methods to solve the problems, such as bend pipe ovality.Want to ensure that the qualified unique method of bend pipe ovality is to maintain
Temperature and speed are consistent, reinforce to the cooling at heating red tape.
Invention content
To overcome defect of the existing technology, the present invention to provide a kind of hot-bending bends inductor limit cooling device,
It can ensure bent tube technique of the fire bending with straight section in the state of not parking,
The both ends that heating temperature and push system speed unanimously simmer system carry the bend pipe of straight pipe, solve that bend pipe ovality is underproof asks
Topic.On this basis, ensure the heating temperature required during temperature is accurate and bent tube technique measured by infrared thermometer
Degree.It avoids the problem that the security risk caused by bend pipe spray cooling water and technique material section is long that product cost is caused to increase.
In order to achieve the above object, using following technical scheme：A kind of hot-bending bends inductor limit cooling device, including
Inductor cooling device head, the first stroke tube body, the second stroke tube body and water-cooled cable；
The inductor cooling device head is hollow ball heads shape, wherein big end is spherical, and small end is tubular opening end, ball
Shape face is equipped with annular slot, and variable frequency induction device is mounted in the annular slot of inductor cooling device head, variable frequency induction device
The hollow interior in inductor cooling device head is arranged in connector, and spherical is equipped with several cooling water apopores, inductor cooling dress
The small end for setting head is connect by flange with the head of the first stroke tube body；
The second stroke tube body is equipped with cooling water inlet opening, and gland and seal assembly are installed in the tail portion of the second stroke tube body,
Head is connect with the tail portion of the first stroke tube body, and inductor cooling device head, the first stroke tube body and the second stroke tube body are formed
The shell of device；
Inside housings, water-cooled cable head end passes through inductor quick coupling and variable frequency induction device for the water-cooled cable installation
The connection of connector, tail end are pierced by from the gland of the second stroke tube body tail portion, and tail end installs power connection.
