Description
Technical field
The present invention relates to processing hot-bending bends technical field, more particularly to 90 ° or more hot-bending bends are processed in a kind of guarantee
Radius accuracy apparatus.
Background technology
In the industrial installations such as nuclear industry, petrochemical industry, aircraft carrier, nuclear submarine, escort vessel, oil tanker, electric power, boiler,
It conveys liquid, gas, solid particle and all largely uses wide-angle hot-bending bends.Especially nuclear submarine, nuclear industry, petrochemical industry add
For hydrogen cracker substantially using import bend pipe, main cause is that the hot-bending bends radius more than 90 ° changes larger, special material
Material is to carry out heating drawing and reparation after not allowing molding.If do not repaired, radius seriously will be unable to assembly beyond tolerance and use,
So home products is used with heating after drawing is repaired.Wide-angle bend pipe is limited by volume and shape, is carried out heating and is led
Draw repair after, heat treatment, ball blast surface treatment it is all highly difficult, even if complete by force it is very huge if Expenses Cost, be equal to weight
The new cost for simmering a piece bend pipe of system, can not also be restored to the mechanical performance of original base material after reparation.
Invention content
To overcome defect of the existing technology, a kind of guarantee of present invention offer to process 90 ° or more hot-bending bends radiuses essences
Device is spent, in processing bend pipe operation, ensures elbow radius size in high-precision acceptability limit.
In order to achieve the above object, using following technical scheme：90 ° or more hot-bending bends radius precision dresses are processed in a kind of guarantee
It sets, including turret base, tube bending jig turntable is installed in turret base, tube bending jig, bend pipe folder are installed on tube bending jig turntable
Tool turntable also installs secondary stationary fixture, and secondary stationary fixture includes support fixture plate a, support fixture plate b, support cylinder and folder
Locking oil cylinder, support fixture plate a and support fixture plate b are respectively equipped with half card slot of bend pipe, and two and half card slots are closed to form bend pipe card slot,
Axis connection during support fixture plate a and support fixture plate b is closed by fixture, the upper edge of support fixture plate a are equipped with to extend and fix
Clamping cylinder is installed in the upper edge of slot, support fixture plate b, and the piston rod of clamping cylinder extends through fixing groove and inserted by limiting
Plate is fixed；For support cylinder by support cylinder floor installation on tube bending jig turntable, the piston rod of support cylinder passes through flange
Component is mounted on the side of support fixture plate b along upper.
Further, the side of support fixture plate a is along equipped with hanging ring.
Advantageous effect of the present invention：Simple in structure, cost is extremely low, installation and convenient disassembly.It is curved in processing 90 ° or more
Pipe is, it can be achieved that not parking operation carries out secondary simmering and bending.Make stewing bend pipe carry out second when reaching 90 ° to clamp, be equivalent to surplus
Under angle from zero simmering and bending, it is ensured that wide-angle elbow radius is qualified.

Specific implementation mode
Embodiment
It further illustrates below in conjunction with the accompanying drawings, if 90 ° or more hot-bending bends radius accuracy apparatus are processed in a kind of guarantees of Fig. 1,
Including turret base（24）, turret base（24）Upper installation tube bending jig turntable（13）, tube bending jig turntable（13）Upper installation is curved
Pipe clamp（16）With secondary stationary fixture.Secondary stationary fixture includes support fixture plate a（1）, support fixture plate b（2）, support oil
Cylinder（3）And clamping cylinder（4）.Support fixture plate a（1）With support fixture plate b（2）It is respectively equipped with half card slot of bend pipe, two and half cards
Slot is closed to form bend pipe card slot（6）, support fixture plate a（1）With support fixture plate b（2）It is closed axis by fixture（7）Connection.
Support fixture plate a（1）Upper edge be equipped with extend fixing groove（8）, support fixture plate a（1）Side along be equipped with hanging ring（14）.
Support fixture plate b（2）Upper edge install clamping cylinder（4）, the piston rod of clamping cylinder（5）Extend through fixing groove（8）And
By limiting plate（9）It is fixed.Support cylinder（3）Pass through support cylinder pedestal（11）Mounted on tube bending jig turntable（13）On,
The piston rod of support cylinder（10）Pass through flange assembly（12）Mounted on support fixture plate b（2）Side along upper.
As shown in fig. 6, it is two parts process, first part's process that this bend pipe, which simmers process processed,：Bend pipe push machine（15）With it is curved
Pipe clamp（16）Respectively by workpiece（18）It clamps, Medium frequency induction circle（17）After heating reaches temperature, bend pipe pushing Oil cylinder（19）
Pushing workpiece（18）Advance, forces tube bending jig（16）And tube bending jig turntable（13）By half radial side rotation of setting, make work
Part（18）Become to set the bend pipe of radius.Work as workpiece（18）In pushing within 90 °, stress point is to step up two pairs of rollers c（20）And
Step up two pairs of rollers b（21）, tube bending jig（16）With tube bending jig turntable（13）Stress simultaneously belongs to normal bending clockwise, workpiece
（18）Radius is constant.When workpiece is more than 90 °, stress point is no longer to step up two pairs of rollers c（20）With step up two pairs of rollers b（21）, but add
Tight two pairs of rollers a（22）, step up two pairs of rollers d（23）And tube bending jig（16）With tube bending jig turntable（13）Stress simultaneously.Because of stress point
Change, workpiece（18）The push-pull effort of bending process be changed therewith, so 90 ° of later elbow radius have larger change
Become, serious non-compliance processes the requirement of drawing.Second part process：It is when workpiece pushing is to 90 °, in not parking state
Under, use support cylinder（3）It moves ahead support fixture plate b（2）Overhead workpiece（18）Inner arc, by support fixture plate a（1）With support
Jig plate b（2）Close up, the piston rod of clamping cylinder（5）Extend through fixing groove（8）, and by limiting plate（9）It is fixed, it will
Support fixture plate a（1）With support fixture plate b（2）Locking.It is equal to when workpiece simmers system to 90 ° and has done secondary clamping, workpiece（18）
Again more fixed points, are equivalent to since 90 °, workpiece（18）From zero restarting, simmering and bending again, it is ensured that big angle
It is qualified to spend elbow radius.
