On, for pushing down plate when shear.The rear side of rack is equipped with top support beam 13, which can further increase
The structural strength of rack.
It for hydraulic plate shears, during welding, inevitably will appear deformation, cut due to commonly middle-size and small-size
Trigger deformation is smaller, 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, since the front plate is longer, deformation quantity is more prominent, is not overcome, can serious shadow
Ring the product processing quality of plate shearing machine and the service life of itself.
In view of the above-mentioned problems, present embodiments provide a kind of processing technology of large hydraulic plate shearing machine rack, in conjunction with Fig. 1,
Its procedure of processing are as follows:
Two step 1, processing wallboards, and upper roller axis hole 15 and bottom roller axis hole 16 are processed on wallboard；Plate in front
Cross machine idler wheel axis hole 22 on 21, and binder seat 23 and front panel 21 are welded together.The processing of wallboard and front panel can
It carries out, is independent of each other between the two respectively.But in processing upper roller axis hole 15, bottom roller axis hole 16 and transverse-roller axis hole 22
When, 0.5~1.5mm surplus is reserved, reserved 1mm surplus may be selected, other numerical value also may be selected, select according to specific needs, do not have
There is concrete restriction.
Step 2 is welded together to form worktable panel 41 and main supporting plate 42, auxiliary supporting plate 43 bracket, main supporting plate 42,
Auxiliary supporting plate 43 is each perpendicular to worktable panel 41；Then mounting surface 441 is cut to requiring ruler on processing work deck plate 41
It is very little.
The working face of worktable panel 41 will be used as machining benchmark, it is necessary to the precision of working face after guarantee welding, and plate
Material welding when easily generate thermal deformation, therefore, how welding when guarantee worktable panel 41 machining accuracy it is particularly significant.
The main function of bracket is to provide bottom bearing capacity when shearing, mainly by worktable panel 41,42 and of main supporting plate
Supporting plate 43 is assisted to form.When welding, tool apron adjustable plate 31 is first welded on worktable panel 41, then by worktable panel 41, main
Supporting plate 42 and auxiliary supporting plate 43 weld together.After the completion of welding, the upper surface of processing work deck plate 41 makes worktable panel
Mounting surface 441 is cut to desired size on 41, and surface is horizontal plane.Mounting surface 441 is cut for installing lower 32 He of tool apron
Lower knife body 33.
As shown in Figure 4, main supporting plate 42 is vertically arranged, and auxiliary supporting plate 43 is vertically arranged.In order to increase structural strength, in master
The bottom position of supporting plate 41 and auxiliary supporting plate 43 is connected with yoke crosstie 44, the yoke crosstie 44 main supporting plate when can prevent from welding
42 and auxiliary the internally deformation of supporting plate 43, have certain thermal deformation supporting role.Also loss of weight can be opened up on auxiliary supporting plate 43
Auxiliary 43 structural strength of supporting plate is reinforced in hole 45.
Common mode in order to facilitate processing, in many cases can first processing work face, then be welded to connect, lead to bracket
Inside is there are thermal stress, the service life of deformation quantity meeting serious curtailment plate shearing machine when using in the later period.And in the present embodiment first
Welding, then processed, the influence so as to avoid welding deformation to working face precision, help to improve the processing essence of complete machine
Degree.
The first wallboard 11 in step 3, fixed wallboard, 11 split of front panel 21 and the first wallboard, and spot welding positions；So
After lift the second wallboard 12 and make itself and 21 split of front panel, spot welding positioning；Then front panel 21 and two wallboards are welded and fixed；
Feeding pressure mechanism 24 can be mounted on 23 lower surface of binder seat after welding.
Weld spot welding tab order when wallboard are as follows: point at the top position that first plate 21 is contacted with the first wallboard 11 in front
Then weldering is divided to two sections of spot welding in the outside of stitching portion, every section of spot welding length is 80mm；In conjunction with Fig. 5, first 1. locate spot welding in position,
Front panel is prevented to be detached from, Primary Location；Then 2. locate to weld positioning section, weld length 80mm in position；Then position 3.
Place's welding positioning section, weld length 80mm.
Then according to same the second wallboard of sequence spot welding 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.
Welding sequence when specific welding are as follows: welded from the bottom to top from front panel 21 and the inside of 11 stitching portion of the first wallboard
It connects；Then it is welded from the bottom to top from front panel 21 and the inside of 12 stitching portion of the second wallboard；According to same welding sequence, in the past
Panel 21 and the outside of 11 stitching portion of the first wallboard are welded from the bottom to top；From the outside of 12 stitching portion of front panel 21 and the second wallboard
It welds from the bottom to top.
Due to first carrying out segmented welding positioning on the outside, when being welded from inside, it can avoid front panel 21 and misplace；This
Outside, after front panel 21 and wallboard inside are welded, front panel can have a degree of deformation, can pass through control front panel 21 at this time
Open area is spread to offset deformation with the leg of stitching portion on the outside of wallboard, is reduced thermal deformation, is obtained preferable welding quality.
Step 4 is welded to connect top support beam 13 between two wallboards, forms rack framework.
Since hydraulic plate shears does not need the lateral long axis of setting, before being only located on front side of wallboard between two wallboards
Panel, is easy to appear deformation on rear side of wallboard, i.e. the left part of Fig. 2 deadlight is easy to appear deformation, and the top braces of welding
Beam 13 is located at the upper left quarter of wallboard, to realize that side is fixed before and after wallboard, improves the structural strength of rack.
Step 5 is lifted into the bracket welded in step 2 on the plummer on front side of wallboard, and adjusts bracket locations, in work
The wallboard outer surface junction spot welding for making deck plate 41 and rack framework two sides positions, then using discontinuous welding method support
Frame is welded and fixed.
Since the mounting surface 441 that cuts on worktable panel 41 will be as machining benchmark, the main point of bracket welding exists
The precision of mounting surface 441, strict control deformation are cut in guarantee.Therefore, it needs to process rack framework two sides before mounting bracket
Wallboard plummer upper surface, be located at same level height.
Wherein discontinuous welding refers to welds multistage in same contact line, rather than directly welds whole weldering
Seam, as in Fig. 5 position 2. and position 3. between interruption welding manner.It is general only locally to generate shape since interruption is welded
Become, will not influence entire main supporting plate and auxiliary supporting plate.
It is worth noting that carrying out discontinuous welding by the way of to welded corner joint, main supporting plate 42 and the first wall are first welded
Then the junction of plate 11 welds auxiliary supporting plate 43 and the junction of the second wallboard 12, then weld main supporting plate 42 and the
Two wallboards, 12 junction, finally welding assists the junction of supporting plate 43 and the first wallboard 11.
The mounting surface 441 that cuts of worktable panel will be as the benchmark of following process, it is necessary to guarantee the welding essence of bracket
Degree.By welding to angie type, the thermal deformation generated when welding can be made to cancel out each other；And main supporting plate plays main support work
With first welding main supporting plate can guarantee its support strength, then weld diagonal auxiliary supporting plate, eliminate thermal deformation；And in
Small-sized hydraulic plate shearing machine, length is shorter, by that can control deformation quantity within the allowable range to welded corner joint, ensure that welding essence
Degree, to provide guarantee for subsequent machining.
Step 6, the straightness for examining front panel 21, mark deformation region, extremely with the middle part in flame gun heat distortion region
650~700 DEG C, water-spraying control；
When being processed with flame gun, if front panel is recessed inwardly, heated from inside flame；If front panel outwardly protrudes,
It is heated from outside flame；Flame region is located at the middle part of recess or protruding parts, and big from deformation region in the vertical direction
The heating of side flame.As shown in Figure 6, it since plate deformation position protrudes outward, is heated according to the direction of arrow A from outside；
Since lower section deformation is greater than top deflection, according to the lower section of the direction flame heating from bottom to top plate of arrow B.Add
It only needs the region between the two lines at middle part to heat when hot, is heated to 680 DEG C, spray water immediately to heating part cold
But, due to panel shrinkage, eliminate or reduce deformation.
Step 7, the weld seam welded along discontinuous, again weld whole weld seam of the junction of bracket and wallboard.
The mounting surface 441 that cuts of worktable panel on bracket will be as mach datum level, it then becomes necessary to guarantee
Its precision just can make following process, installation accuracy be protected, and after the welding of first time discontinuous, entire rack is positioned and fixed,
It is heated by flame after eliminating deformation, then carries out secondary welding, completed the welding processing of whole seam, on the one hand can be avoided deformation
Accumulation, on the other hand can reduce partial shape variable when secondary welding, fully ensure that the precision of datum level.
Rack after welding is transported to machining center by step 8, is with the mounting surface 441 that cuts on worktable panel 41
Benchmark is machined out, manufacturing procedure are as follows:
The lateral surface of S1, the upper roller axis hole 15 for processing the first wallboard 11 and bottom roller axis hole 16 keep its lateral surface perpendicular
It faces directly；
S2, the upper roller axis hole 15 for processing the first wallboard 11 and bottom roller axis hole 16 to desired height and internal diameter,
Keep the axis of idler wheel axis hole vertical with its lateral surface；
S3, processing make its lateral surface perpendicular to base close to the lateral surface of the transverse-roller axis hole 22 of 11 side of the first wallboard
Quasi- face；
S4, cross machine idler wheel axis hole 22 to desired height and internal diameter, the axis of transverse-roller axis hole 22 and its
Lateral surface is vertical；
S5, the other end of rack is processed according to the step of S1~S4.
Frame processing is carried out using the complete machine processing method after welding, can further eliminate micro deformation to machining accuracy
It influences, upper roller axis hole, bottom roller axis hole and transverse-roller axis hole can guarantee the installation accuracy of upper tool post, on the other hand can protect
