The weld seam of one section of 30mm length is welded, main support plate 32 is then completed from the bottom to top successively and joins with the first wallboard 11, the second wallboard 12
The welding at place；Auxiliary support plate 33 is welded with the first wallboard 11, the junction of the second wallboard 12 again, finally to worktable panel
Welded with the first wallboard 11, the second wallboard 12.
Positioned because elder generation carries out segmentation welding in auxiliary support plate, when welding main support plate, main support plate can be avoided to misplace；This
Outside, after main support plate is welded with wallboard, worktable panel can have a certain degree of micro-strain, now can also pass through and control to aid in
Support plate offsets deformation with the leg paving open area of stitching portion on the outside of wallboard, reduces thermal deformation, obtains preferable welding quality.
Step 6, frame is transported to complete machine machining center, the upper surface of processing work deck plate 31 makes on worktable panel
Lower knife mounting surface 311 and main shaft between distance meet desired size.
If distance is undesirable between lower knife mounting surface 311 and main shaft, the movement travel of upper knife body is not enough, then can not
Complete shearing；If stroke is excessive, processing efficiency can be reduced, Cutter wear is larger, it then becomes necessary to ensure both spacing.
The present embodiment can meet the requirement using the order for first installing post-processing.
On the basis of step 7, following knife mounting surface 311, processing bottom roller axis hole 15, upper roller axis hole 16 and transverse-roller axle
Desired size is arrived in hole 22.Its specific manufacturing procedure is：
S1, the bottom roller axis hole 15 for processing the first wallboard 11 and upper roller axis hole 16 lateral surface, it is perpendicular to make its lateral surface
Face directly；
S2, process the first wallboard 11 bottom roller axis hole 15 and upper roller axis hole 16 to desired height and internal diameter size,
Make the axis of roller axis hole vertical with its lateral surface；
S3, processing make its lateral surface perpendicular to reference plane close to the transverse-roller axis hole 22 of the side of the first wallboard 11；
S4, cross machine roller axis hole 22 to desired height and internal diameter size, the axis of transverse-roller axis hole 22 and its
Lateral surface is vertical；
S5, according to being processed the step of S1~S4 to the other end of frame.
Frame processing is carried out using the complete machine processing mode after welding, micro deformation can be further eliminated to machining accuracy
Influence, 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
Upper tool post is demonstrate,proved to move in vertical direction.Further, since the raising of precision, the deformation that plate shearing machine exists when working is reduced, contribute to
Improve the service life of plate shearing machine.
