For the perforation that seven upper mould laminations are connected and fixed, multiple upper mould lamination 5-1 are by being installed on the bolt in perforating
Link together.Curvature, which is also arranged at intervals with, in the peripheral side of the upper mould lamination is far longer than the part to be corrected to be corrected
The arc groove of 9 design curvature.
The curved arc correcting tool also includes the detection model 8 for detecting whether part 9 to be corrected is up to standard, the detection model 8
On be provided with the arc groove consistent with the design curvature for the part to be corrected 9 to be corrected.
Seven lower mould lamination 4-1 parallel side-by-sides arrangements when mounted, are sleeved on two lower moulds by the curved arc correcting tool
On installation axle top, then seven lower mould laminations are connected and fixed by bolt, formed on lower mould 4, two lower moulds 4
Two are received arc fit on face 4-3 on same arching trajectory.Seven upper mould lamination 5-1 parallel side-by-sides are installed installed in upper mould
On axle 6, then seven upper mould laminations are fixed together by bolt, mould in formation.
The curved arc correcting tool when in use, part 9 to be corrected is put into the arc groove for detecting model 8, if treated
Two side contacts of correcting member and arc groove, do not contact with the bottom of arc groove, there is gap（As shown in Figure 3）, illustrate to treat school
The curvature of positive part 9 is less than design curvature, and degree of crook kicks the beam, it is necessary to which treating correcting member 9 carries out receipts arc.Now, measure first
Part 9 to be corrected, apart from H, is then open with arc groove bottom and is placed into curved arc correcting tool towards upper mould 5 by part to be corrected
On（As shown in Figure 4）, the outer arcuate face of part 9 to be corrected coordinates with the receipts arc fit on face 4-3 on lower mould 4 to be contacted.Operate liquid
The upper mould 5 of press driving is moved to part 9 to be corrected, makes the inner side arcwall face center of part 9 to be corrected with matching somebody with somebody in the receipts arc on upper mould 5
Conjunction face 5-3 coordinates contact, and now upper mould 5 is in top pressure starting point, and upper mould 5 continues along the original side of movement by starting point of top pressure starting point
To mobile 0.5H, part 9 to be corrected curvature under the top pressure effect of upper mould 5 increases, and opening diminishes, and afterwards, upper mould 5 is back to top pressure
Starting point, the top pressure operation before then repeating, untill part to be corrected reaches design curvature and is maintained at design curvature.
If part to be corrected is contacted with the bottom of arc groove, and is not contacted with the both sides of arc groove, there is gap（As schemed
Shown in 5）, illustrate that the curvature of part to be corrected is more than design curvature, the degree of crook of part to be corrected is excessive, it is necessary to treat correcting member 9
Carry out expansion arc.Now, the approximate distance h of the side of part 9 to be corrected and arc groove side is rule of thumb measured first, then will
Part opening to be corrected is placed on curved arc correcting tool towards lower mould 4（As shown in Figure 7）, the inner side arcwall face of part 9 to be corrected with
Mating surface 4-2 coordinates contact in expansion arc on lower mould 4.The upper mould 5 of operation hydraulic press driving is moved to part 9 to be corrected, is made to be corrected
The outer arcuate face center of part coordinates with the expansion arc fit on face 5-2 on upper mould 5 to be contacted, and now upper mould 5 sets out in top pressure
Point, upper mould 5 continues to move 1.5h along former direction by starting point of top pressure starting point, and part 9 to be corrected is bent under the top pressure effect of upper mould 5
Rate reduces, and opening becomes big, afterwards, and upper mould 5 is back to top pressure starting point, the top pressure operation before repeating, until part 9 to be corrected reaches
Untill designing curvature and being maintained at design curvature.
After long-term use, can be by lower mould 4 or upper mould 5 from lower mould installation axle 3 if lower mould 4 or upper mould 5 deform
Or take off and changed in upper mould installation axle 6, without whole device is changed.
If part 9 to be corrected is all fitted with the bottom surface and side of arc groove, illustrate that the curvature of part to be corrected and design are bent
Rate is consistent, it is not necessary to be corrected again.
, can be with if the arc length for the part to be corrected to be corrected is long as another embodiment of the present utility model
By the way of Stepwise calibration, if to be divided into N sections of corrections, every section on timing mould 5 need the edge since top pressure starting point
Former moving direction moves 0.5H/N or 1.5h/N distance.
As another embodiment of the present utility model, the lower mould lamination 4-1 and upper mould lamination 5-1 can not also be set
Seven are put, can be according to mould lamination 4-1 and upper mould lamination under the length adjustment of the part to be corrected 9 to be corrected in the axial direction
5-1 number, makes the length of lower mould 4 and upper mould 5 with part 9 to be corrected in the axial direction consistent, makes part 9 to be corrected in top pressure school
Along axis of bending direction uniform force during just.
As another embodiment of the present utility model, described two lower moulds 4 can also be bigger by a volume
Support base is replaced, and the support base is arranged on the underface of the upper mould 5, the support base one side center relative with upper mould 5
The receipts arc fit on face 4-3 for coordinating with part outer arcuate face to be corrected is provided with position, the support base is also being received
Arc fit on face 4-3 both sides be provided with for part to be corrected on the inside of arcwall face coordinate expansion arc in mating surface 4-2.Which
It is suitable for the less situation of size of part to be corrected, if part to be corrected is oversized, then the support pedestal which is manufactured
Product is excessive, can cause the waste of material, increases production cost.
As another embodiment of the present utility model, the expansion arc fit on face 5-2 and receipts arc fit on face 4-3
The arcwall face caved inward can be not provided with into, and is arranged to plane.This mode manufacture craft is simple, but may make in top pressure
Industry leaves top pressure vestige after terminating on the surface of part 9 to be corrected.
As another embodiment of the present utility model, the lower mould installation axle 3 can not also pass through side and lower mould
Bearing 2 is connected, but two ends are fixed on lower mould bearing 2, although lower mould installation axle 3 can also be fixed on lower mould by this mode
On bearing 2, but the curved arc correcting tool of lower mould installation axle 3 can undertake the pressure on top surface that mould treats correcting member indirectly when using, under
The two ends of mould installation axle 3 are fixed and centre can vacantly cause the bearing capacity of lower mould installation axle 3 to decline, and are easily bent deformation, even
Fracture damage.And this structure is unfavorable for the installation and taking-up of lower mould 4.The upper mould installation axle 6 can also be arranged to two ends
Fixed, middle hanging mode is equally also unfavorable for the stress of upper mould installation axle and the installation and taking-up of upper mould.
As another embodiment of the present utility model, the upper mould 5 or lower mould 4 it can also be provided that integrative-structure,
This mode manufacture craft is simple, but a kind of part to be corrected of width can only be corrected, narrow application range.
As another embodiment of the present utility model, the lower mould mounting structure is it can also be provided that lower mould and lower mould
Installation axle is fixedly connected, and the connected mode that lower mould installation axle can be rotated relative to lower mould bearing.
