Embodiment 1
In conjunction with Fig. 2, Fig. 3, hydraulic pressure compression shear trigger includes the first wallboard 11 and the second wallboard 12, front panel 21, carries work
The bracket of deck plate 41, the first wallboard 11 and the second wallboard 12 are distributed in the both sides of frame, play main support effect, therein
First, second simply facilitates differentiation description, and the practical structures of plate shearing machine are not specifically limited.Before front panel 21 is located at frame
Side, the binder seat 23 of front panel 21 lower section is used for fixing feeding pressure mechanism 24, and this feeding pressure mechanism is bolted in binder seat 23
On, push down sheet material during for shear.The rear side of frame is provided with top support beam 13, and this top support beam 13 can improve further
The structural strength of frame.
For hydraulic plate shears, in welding processing, deformation inevitably occurs, cut due to commonly middle-size and small-size
Trigger deformation is less, and most enterprises can take the measure of amplification reserve to solve deformation problems, but this method can reduce processing
Precision.For large-scale plate shearing machine, because its front panel is longer, its deformation quantity is more prominent, is not overcome, can serious shadow
Ring product processing quality and the service life of itself of plate shearing machine.
For the problems referred to above, present embodiments provide a kind of processing technique of large hydraulic plate shearing machine frame, in conjunction with Fig. 1,
Its procedure of processing is：
Step 1, two wallboards of processing, and processing upper roller axis hole 15 and bottom roller axis hole 16 on wallboard；In front panel
Cross machine roller axis hole 22 on 21, and binder seat 23 is welded together with front panel 21.The processing of wallboard and front panel can
Carry out respectively, be independent of each other between the two.But in processing upper roller axis hole 15, bottom roller axis hole 16 and transverse-roller axis hole 22
When, reserve 0.5～1.5mm surplus, reserved 1mm surplus may be selected, also other numerical value may be selected, select according to specific needs, do not have
There is concrete restriction.
Step 2, worktable panel 41 is welded together to form bracket with main support plate 42, auxiliary support plate 43, main support plate 42,
Auxiliary support plate 43 is each perpendicular to worktable panel 41；Then the lower knife installed surface 441 on processing work deck plate 41 is to requiring chi
Very little.
The work surface of worktable panel 41 will be as machining benchmark it is necessary to ensure the precision of work surface after welding, and plate
Material easily produces thermal deformation in welding, therefore, how to ensure that the machining accuracy of worktable panel 41 is particularly significant in welding.
The Main Function of bracket is bottom bearing capacity when providing shearing, mainly by worktable panel 41, main support plate 42 and
Auxiliary support plate 43 forms.During welding, first on worktable panel 41, weld tool rest adjustable plate 31, then by worktable panel 41, main
Support plate 42 and auxiliary support plate 43 weld together.After the completion of welding, the upper surface of processing work deck plate 41, make worktable panel
To desired size, its surface is horizontal plane to lower knife installed surface 441 on 41.Lower knife installed surface 441 is used for installing lower tool rest 32 He
Lower knife body 33.
As shown in Figure 4, main support plate 42 is vertically arranged, and auxiliary support plate 43 is vertically arranged.In order to increase structural strength, leading
Support plate 41 is connected with yoke crosstie 44 with the bottom position of auxiliary support plate 43, and this yoke crosstie 44 is prevented from main support plate during welding
42 and auxiliary support plate 43 internally deformation, there is certain thermal deformation supporting role.Also loss of weight can be opened up on auxiliary support plate 43
Hole 45, strengthens auxiliary support plate 43 structural strength.
Common mode is processed for convenience, in many cases can first processing work face, be welded to connect, led to bracket
There is thermal stress in inside, the service life of its deformation quantity meeting serious curtailment plate shearing machine when using in the later stage.And in the present embodiment first
Welding, being processed, thus avoiding the welding impact to work surface precision for the deformation, being favorably improved the processing essence of whole machine
Degree.
The first wallboard 11 in step 3, fixing wallboard, front panel 21 and the first wallboard 11 split, and spot welding positioning；So
After lift the second wallboard 12 and make it with front panel 21 split, spot welding positions；Then front panel 21 is welded and fixed with two wallboards；
Feeding pressure mechanism 24 can be arranged on binder seat 23 lower surface after welding.
Welding spot welding tab order during wallboard is：First point at the tip position that front panel 21 is contacted with the first wallboard 11
Weldering, then divide the outside in stitching portion two sections of spot welding, and every section of spot welding length is 80mm；In conjunction with Fig. 5, first 1. locate spot welding in position,
Prevent front panel from departing from, Primary Location；Then 2. locate to weld positioning section in position, weld length is 80mm；Then in position 3.
Place's welding positioning section, weld length is 80mm.
Then according to same order spot welding the second wallboard 12 and front panel 21, front panel 21 is made to be fixed on the first wallboard
11 and second between wallboard 12, and three position is determined.
Specifically welding sequence during welding is：Weld from the bottom to top from the inner side of front panel 21 and the first wallboard 11 stitching portion
Connect；Then weld from the bottom to top from the inner side of front panel 21 and the second wallboard 12 stitching portion；According to same welding sequence, in the past
Panel 21 is welded from the bottom to top with the outside of the first wallboard 11 stitching portion；Outside from front panel 21 and the second wallboard 12 stitching portion
Weld from the bottom to top.
Due to first carrying out stagewise welding positioning in outside, when from interior survey welding, front panel 21 can be avoided to misplace；This
Outward, after welding inside front panel 21 and wallboard, can there is a certain degree of deformation in front panel, now can be by controlling front panel 21
To offset deformation with the leg paving open area of stitching portion outside wallboard, to reduce thermal deformation, obtain preferable welding quality.
Step 4, it is welded to connect top support beam 13 between two wallboards, form rack framework.
Because hydraulic plate shears does not need to arrange horizontal major axis, before being only located on front side of wallboard between two wallboards
, easily deformation in panel on rear side of wallboard, that is, deforming easily occurs in the left part of Fig. 2 deadlight, and the top braces welded
Beam 13 is located at the upper left quarter of wallboard, thus realize side before and after wallboard all being fixed, improves the structural strength of frame.
Step 5, the bracket of welding in step 2 is lifted on the plummer on front side of wallboard, and adjusts bracket locations, in work
Make the wallboard outer surface junction spot welding positioning of deck plate 41 and rack framework both sides, then adopt discontinuous welding method support
Frame is welded and fixed.
Because the lower knife installed surface 441 on worktable panel 41 will be as machining benchmark, the main point of this bracket welding exists
In the precision ensureing lower knife installed surface 441, strictly control deformation.Therefore, need to process rack framework both sides before mounting bracket
Wallboard plummer upper surface so as to be located at same level height.
Wherein said discontinuous welding refers to weld multistage in same contact line, rather than directly welding whole piece weldering
In seam, such as Fig. 5 position 2. and position 3. between interruption welding manner.Due to interruption welding, general only meeting produces shape in local
Become, do not interfere with entirely main support plate and auxiliary support plate.
What deserves to be explained is, carry out discontinuous welding by the way of to welded corner joint, first weld main support plate 42 and the first wall
The junction of plate 11, is then welded with the junction of the second wallboard 12 to auxiliary support plate 43, then welds main support plate 42 and the
Two wallboard 12 junction, the finally junction of welding auxiliary support plate 43 and the first wallboard 11.
The lower knife installed surface 441 of worktable panel will be as the benchmark of following process it is necessary to ensure the welding essence of bracket
Degree.By welding to angie type, the thermal deformation producing during welding can be made to cancel out each other；And main support plate plays main support and makees
With first welding main support plate and can ensure its support strength, then weld diagonal auxiliary support plate, eliminating thermal deformation；And in
Small-sized hydraulic plate shearing machine, its length is shorter, by deformation quantity can be controlled in allowed band it is ensured that welding is smart to welded corner joint
Degree, thus provide guarantee for follow-up machining.
Step 6, the glacing flatness of inspection front panel 21, mark deformation region, with the middle part in flame gun heat distortion region extremely
650～700 DEG C, water-spraying control；
When being processed with flame gun, if front panel caves inward, from the heating of inner side flame；If front panel is outwardly,
From the heating of outside flame；Flame region is located at the middle part of depression or protruding parts, and in the vertical direction is big from deformation region
Side flame heating.As shown in Figure 6, due to sheet material deformation position outwardly, heat from outside according to the direction of arrow A；
Because lower section deformation is more than top deflection, therefore, according to the lower section of the direction flame heating from bottom to top sheet material of arrow B.Plus
Only need to when hot heat along the region between the two lines at middle part, be heated to 680 DEG C, spray water to heating part immediately cold
But, due to panel shrinkage, eliminate or reduce deformation.
Step 7, the weld seam along discontinuous welding, weld to the whole piece weld seam of bracket and the junction of wallboard again.
The lower knife installed surface 441 of the worktable panel on bracket will be as mach datum level, it then becomes necessary to ensure
Its precision, just can make following process, installation accuracy be protected, and after the welding of first time discontinuous, whole frame is positioned fixation,
After flame heating eliminates deformation, then carry out secondary welding, complete the welding processing of whole piece seam, on the one hand it can be avoided that deformation
Accumulation, on the other hand can reduce local deformation amount during secondary welding, fully ensure that the precision of datum level.
Step 8, welding after frame be transported to machining center, with the lower knife installed surface 441 on worktable panel 41 be
Benchmark is machined out, and its manufacturing procedure is：
The lateral surface of S1, the upper roller axis hole 15 of processing the first wallboard 11 and bottom roller axis hole 16 is so as to lateral surface is perpendicular
Face directly；
S2, the processing upper roller axis hole 15 of the first wallboard 11 and bottom roller axis hole 16 to the height requiring and internal diameter size,
Make the axis of roller axis hole vertical with its lateral surface；
S3, the transverse-roller axis hole 22 near the first wallboard 11 side for the processing are so as to lateral surface is perpendicular to datum level；
S4, cross machine roller axis hole 22 to the height requiring and internal diameter size, the axis of transverse-roller axis hole 22 and its
Lateral surface is vertical；
S5, according to the step of S1～S4, the other end of frame is processed.
Frame processing is carried out using the whole machining mode after welding, micro deformation can be eliminated further to machining accuracy
Impact, upper roller axis hole, bottom roller axis hole and transverse-roller axis hole can ensure the installation accuracy of upper tool post, on the other hand can protect
Card upper tool post moves in vertical direction.Further, since the raising of precision, the deformation existing during plate shearing machine work reduces, and contributes to
