And 4, splicing the front panel 21 at the upper end of the front side of the wallboard, performing spot welding positioning, and then completing welding and fixing by adopting a cross welding mode. Adopt the cross welding mode to weld when welding front panel 21 and fix, its order is:
s1, welding the upper and lower combination points on the inner sides of the first wall board 11 and the front panel 21, and then welding the middle combination point on the outer sides of the second wall board 12 and the front panel 21;
s2, welding the upper and lower joint points of the second wall board 12 and the inner side of the front panel 21; then welding the middle joint point of the first wall plate 11 and the outer side of the front panel 21;
s3, welding the middle combination points of the first wall board 11 and the inner side of the front panel 21, and then welding the upper and lower combination points of the second wall board 12 and the outer side of the front panel 21;

Because the auxiliary support plate is firstly subjected to sectional welding positioning, the main support plate can be prevented from being misplaced when the main support plate is welded; in addition, after the main support plate is welded with the wall plate, the workbench panel can have a certain degree of micro deformation, and at the moment, the deformation can be offset by controlling the weld leg paving area at the splicing part of the auxiliary support plate and the outer side of the wall plate, so that the thermal deformation is reduced, and better welding quality is obtained.
And 6, conveying the rack to a complete machine machining center, and machining the upper surface of the workbench panel 31 to enable the distance between the lower cutter mounting surface 311 on the workbench panel and the main shaft to meet the required size.
If the distance between the lower cutter mounting surface 311 and the main shaft does not meet the requirement and the movement stroke of the upper cutter body is insufficient, the shearing cannot be finished; if the stroke is excessive, the machining efficiency is reduced, and the tool is worn more, so that the distance between the tool and the tool must be ensured. This embodiment adopts the order of processing after installing earlier, can satisfy this requirement.
And 7, processing the lower roller shaft hole 15, the upper roller shaft hole 16 and the transverse roller shaft hole 22 to required sizes by taking the lower cutter mounting surface 311 as a reference. The specific processing procedures are as follows:
s1, processing the outer side surfaces of the lower roller shaft hole 15 and the upper roller shaft hole 16 of the first wall plate 11 to enable the outer side surfaces to be vertical surfaces;

s4, processing the transverse roller shaft hole 22 to the required height and inner diameter, wherein the axis of the transverse roller shaft hole 22 is vertical to the outer side surface;
and S5, processing the other end of the frame according to the steps from S1 to S4.
The machine frame is machined by adopting a welded whole machine machining mode, the influence of micro deformation on machining precision can be further eliminated, the mounting precision of the upper tool rest can be guaranteed by the upper roller shaft hole, the lower roller shaft hole and the transverse roller shaft hole, and the upper tool rest can be guaranteed to move in the vertical direction. In addition, due to the improvement of the precision, the deformation of the plate shearing machine during working is reduced, and the service life of the plate shearing machine is prolonged.
And 8, mounting the roller in the roller shaft hole, then mounting the tool rest, and finishing the mounting of the rest parts.
The rest parts comprise the installation of components such as a connecting rod, a material pressing mechanism, a material stopping mechanism and the like and the installation of an electric control system, and the rest parts can be realized by adopting a traditional method and are not repeated.

Because the wall plates on the two sides of the small plate shearing machine are thin, the welded thickened plates are beneficial to improving the structural strength, and the whole machining operation in the step 7 is convenient. The outer side surfaces of the upper roller shaft hole 16 and the lower roller shaft hole 15 processed in the step 7 are positioned on the same plane, so that the whole surface can be processed by one-time feeding, and the efficiency is high.
