Description
Technical field
It the utility model is related to a kind of vessel flange, bobbin carriage etc. of being applied to and correct frock, and in particular to one kind heat treatment is rectified
Positive frock.
Background technology
Due to vessel flange, bobbin carriage for a long time be disposed vertically or bobbin carriage be heat-treated when support meanss installation it is improper, cause
Vessel flange, bobbin carriage become just, connection hole site is exceeded deviation requirement, can not normal mounting use, such as very heavy pressure school of use
Circle, in the presence of column defects：1st, because it is very heavy be local correction, it is impossible to accomplish overall control, dead angle unavoidably be present, precision is not high.2、
Springback capacity be present, after gusset or lacing wire revocation, resilience is had at correction.3rd, necessarily there is residual stress after local correction, influence
The quality of product.
Utility model content
Support meanss are pacified when the utility model is solves vessel flange, bobbin carriage long-time is disposed vertically or bobbin carriage is heat-treated
Fill improper, causing vessel flange, bobbin carriage to become just, connection hole site is exceeded deviation requirement, can not the skill that uses of normal mounting
Art problem, there is provided one kind heat treatment correction frock.The circularity that it is applied to flange is corrected, adapt in the vessel flange of DN >=500,
The heat straightenings such as bobbin carriage, circularity regulation.
Technical scheme is used by the utility model：One kind heat treatment correction frock, including it is welded to each other into " ten " word
The connecting tube and outer tube of shape, the both ends of connecting tube are respectively and fixedly provided with an arc plate, and activity is cased with one respectively at the both ends of outer tube
Outer tube is inserted in inner sleeve, one end of inner sleeve, and the other end of inner sleeve has been fixedly connected with an arc plate, between internal and external casing
Realized and positioned by pin；Ultimate range is vessel flange internal diameter to be corrected between the arc plate at connecting tube both ends, the arc plate
Radius is identical with vessel flange internal diameter to be corrected.
Position is placed as shown in Figure 2 when the course of work of the present utility model is is heat-treated, and makes to place vertically at internal diameter increase,
Heat treatment temperature is 620 DEG C ± 20 DEG C（90 DEG C lower than phase transition temperature or so）, vessel flange or bobbin carriage are orthopedic using conducting oneself with dignity, and make water
Square to arc plate be bonded with vessel flange internal diameter, while horizontal direction stretches, and makes the distance between arc plate of horizontal direction two be
Vessel flange internals.Stress and orthopedic purpose are eliminated so as to reach.
The utility model has the advantages that compared with prior art：
The utility model correction frock is smoothed out vessel flange, bobbin carriage correction, not only can guarantee that correction quality, operates
Convenience, safety, correction accuracy it is high and after correcting will not resilience, and avoid equipment strength from correcting stress that may be present.Other pole
Big degree alleviates labor strength.
Brief description of the drawings
Fig. 1 is the practical application schematic diagram using correction frock correcting device flange of the present invention.
Fig. 2 is the utility model heat treatment correction tool structure schematic diagram（Fig. 1 A direction views）.
Marked in figure as follows：
1- arc plates, 2- inner sleeves, 3- pins, 4- outer tubes, 5- gussets, 6- connecting tubes.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Embodiment 1
One kind heat treatment correction frock, including the connecting tube 6 and outer tube 4 of " ten " font are welded to each other into, connecting tube 6
Both ends are respectively and fixedly provided with an arc plate 1, and activity is cased with an inner sleeve 2 respectively at the both ends of outer tube 4, and one end of inner sleeve 2 is inserted in
Outer tube 4, the other end of inner sleeve 2 have been fixedly connected with an arc plate 1, have been realized and positioned by pin 3 between internal and external casing；Even
Ultimate range is vessel flange internal diameter to be corrected between the arc plate 1 at the both ends of adapter 6, and the radius of arc plate 1 is set with to be corrected
Standby flange inner diameter is identical.Pin 3 is set through the hole on outer tube, for being positioned to inner sleeve.
The short tube that the outer tube 4 is fixed on the center both sides of connecting tube 6 by two sections forms, one end of every section of short tube and connection
The center outer tube wall connection of pipe 6, short tube set gusset 5 to realize reinforcement effect with connecting tube 6 in connecting portion.It is heat-treated orthopedic work
Welding is grouped with outer tube 4 in arc plate 1 and inner sleeve 2, arc plate 1 and connecting tube 6, gusset 5 by dress respectively.
Placed during heat treatment by Fig. 2 positions, make to place vertically at internal diameter increase（By the arc plate at connecting tube and its both ends come
Support）, heat treatment temperature is 620 DEG C ± 20 DEG C（90 DEG C lower than phase transition temperature or so）, vessel flange or bobbin carriage are rectified using deadweight
Just, horizontal direction arc plate is made（Inner sleeve both ends arc plate）It is bonded with vessel flange internal diameter, by arc plate center weld and vessel flange
Inner side at internal diameter reduction, while horizontal direction stretches, it is vessel flange internals to make the distance between arc plate of horizontal direction two, so as to
Reach the purpose for eliminating stress and correction.
To improve precision, it can suitably increase arc plate chord length or increase the frock quantity.
The utility model correction frock is mainly using vessel flange at 620 DEG C（90 DEG C lower than phase transition temperature or so）Lower utilization
Deadweight is corrected, and low-alloy vessel flange, which will not be undergone phase transition, at this temperature influences the increase of vessel flange mechanical property and can
Toughness, correct vessel flange.
