Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model embodiment includes body of heater 1, and body of heater 1 includes heating region 1-1 and cooling zone
1-2, herein structure compatible common annealing stove, front and rear on the material landline of body of heater 1 are provided with conveying roller
Road 2, it is characterised in that：It is provided with the rollgang 2 of the both sides of body of heater 1 for being compressed to pipe end to prevent pipeline
There is the anti-bending correcting device 3 of elbow in end, and anti-bending correcting device 3 includes pressure roller 3-1 and carrying roller 3-2, pressure roller 3-1 and carrying roller
The amendment passage 3-3 for the deformation of restriction conduit termination is provided between 3-2, amendment passage 3-3 major diameter is with pressure roller 3-1
To press and reduce, the present embodiment occurs due to after annealing, occurring eyesight elbow after mainly for the steel pipe of production, so that
Situation that the steel pipe produced directly is scrapped and propose the technical scheme of correcting principle, the carrying roller 3-2 in the present embodiment and pressure
Roller 3-1 surface is designed to the structure for coordinating pipe end shape, and one is formed between pressure roller 3-1 and carrying roller 3-2 ensure that
The individual outer surface by pipe end carries out the amendment passage 3-3 of comprehensive compression.By the end of pipeline is the institute in body of heater 1
Holdup time most long part, the degree of its caused phase transformation because of annealing process is maximum, while the knot of pipe end in itself
Structure is also easily deformed elsewhere relatively, and amendment passage 3-3 is set up before body of heater 1 is entered to be carried out to a certain degree to end
Compacting, can so enable pipe end and the degree of transformation at other positions to obtain unanimously, and after pipeline exits body of heater 1,
The structure of pipe end because bend pipe easily occurs for relative other parts, and correct passage 3-3 can be by pipe end now
All directions deformation limitation, while the waste heat of pipe end can also be guided, so as to further speed up cooling, in deformation quilt
Cooled down while limitation end help to be completely eliminated due to annealing process and caused by eyesight elbow phenomenon generation, improve into
Product rate.Carrying roller 3-2 contacts with pipe surface all the time, and pressure roller 3-1 only contacts with pipe end, because carrying roller 3-2 effect is gram
Deformation caused by gravity is made, so carrying roller 3-2 must be all the time with tube contacts, and pressure roller 3-1 is strong for structure
The relatively weak pipe end of degree is set, so only need to be modified pipe end, if pressure roller 3-1 all the time with
Tube contacts, then the fluency of pipeline may be had influence on the contrary, held so as to influence the time of annealing process.Pressure roller 3-1
With carrying roller 3-2 surface from both ends to it is middle it is curved cave in, and pressure roller 3-1 and carrying roller 3-2 arc caves in common group of part
Into amendment passage 3-3.
As shown in Fig. 2 the pressure pipe of the utility model embodiment is arranged at carrying roller 3-2 top, pressure roller 3-1 is filled by lifting
Put 4 and make linear Enhance Sports along perpendicular to carrying roller 3-2 longitudinal center line direction.Lowering or hoisting gear 4 includes fluctuating orbit 4-1, rises
Crane 4-2 is equipped with drop track 4-1, pressure roller 3-1 is rotatably connected on crane 4-2, is set at the top of crane 4-2
Lifter 4-3 is equipped with, lifter 4-3 is telescopic oil cylinder or telescopic cylinder or the fit structure of motor and leading screw.
Anti-bending correcting device 3 includes the front being arranged on the material landline of body of heater 1, for entering to pipe end
The preposition correcting device of row shape amendment and the rear that is arranged on the material landline of body of heater 1, for pipe end
The deformation of mouth is limited and guided the rearmounted correcting device that the heat of pipe end is cooled down；Preposition correcting device is only set
There is a pair of pressure roller 3-1 and carrying roller 3-2；Rearmounted correcting device is repaiied at least provided with two couples of pressure roller 3-1 and carrying roller 3-2 due to preposition
What the pipe end that equipment is directed to just heated after amendment, so preposition correcting device only needs a pair of pressure roller 3-1 and carrying roller 3-2
Pipeline is carried out once to correct, and rearmounted correcting device is directed to the pipeline after annealing, now the port of pipeline is relative
Still it is softer, so at least provided with two couples of pressure roller 3-1 and carrying roller 3-2, when first couple of pressure roller 3-1 and carrying roller 3-2 is to pipe end
Carry out that the partial heat of port can also be guided when profile limitation so that the appropriate recovery of the hardness of port, the second team is successively
Recursion, this ensures that the correction effect of pipe end.At least two couples of pressure roller 3-1 and carrying roller 3-2 of rearmounted correcting device it
Between spacing it is adjustable, the size and thickness of the pipeline of different size are different, thus adjustment spacing can be according to different rule
The pipeline of lattice is adjusted, to ensure that pipe end will not produce unnecessary deformation because spacing is improper.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
