Structure, wherein binder connecting plate 32 is primarily used to installation feeding pressure mechanism, and upper base plate 31 is then for fixing binder connecting plate
32, it is fixed on the rack it.Upper cutter head is often to be mounted on the rack close to the position of upper base plate 31, if upper base plate 31 welds
Deformation is larger when connecing, and entire rack can be made all to there is stress concentration phenomenon, causes structural strength insufficient, when in use, it is easy to
It cracks；It is affected to shear effect, in some instances it may even be possible to will appear sword and split phenomenon, seriously affect cutter and equipment and use the longevity
Life.Therefore, it is necessary to draw to guarantee whole welding quality using second layer welding.
It is worth noting that when welding progress deformation adjustment using the second layer, if 31 evagination of upper base plate, i.e. upper base plate 31
Middle part is protruded to the side for deviateing rack, then second layer welding is carried out on the inside of wallboard, and leg can be to 31 1 lateral deviation of upper base plate
It moves；If arch in upper base plate 31, i.e. 31 middle part of upper base plate is recessed to the side close to rack, then second layer weldering is carried out on the outside of wallboard
It connects.The paving open area that will increase leg after second layer welding is reached due to the difference of welding position and is aligned the seat of honour from different directions

24 can prevent main supporting plate 23 when welding and assist the internally deformation of supporting plate 22, have certain thermal deformation supporting role.
Step 4: needing to carry out spot welding positioning after step 3 adjustment good position.Since bracket overall dimensions are larger, become
Shape very little, main deformation appear in deformation caused by positional shift when first layer welds, and therefore, it is necessary to determine in spot welding
Good welding position.When specific operation, spot welding is carried out using diagonal welding manner, in the junction of main supporting plate 23 and the first wallboard 11
Spot welding positioning；Then spot welding positioning is carried out to the junction of auxiliary supporting plate 22 and the second wallboard 12；Then successively to main supporting plate 23
It is positioned with the second wallboard 12, auxiliary supporting plate 22 and the first wallboard 11 in junction spot welding.
Step 5: knife holder mechanism 25 under installing on the workbench 21 of bracket 2, adjusts lower knife body in lower knife holder mechanism 25
254 straightness.
Step 6: carrying out first layer welding according to the diagonal welding sequence in step 4, after welding, detects and adjust
The straightness of lower knife body 254 carries out second layer welding according to first layer welding sequence, is welded by the second layer and carry out deformation tune
It is whole；
Step 7: completing the installation of operating device, fluid pressure line, distribution line and rest part, step can be according to normal
Rule method is operated, and is repeated no more.
