Problems solved by technology
The cutting quality of disc shears has a lot to do with the side clearance of the cutting edge. Inaccurate measurement and adjustment of the side clearance of the cutting edge will cause the phenomenon of camber bending, sticking steel at the edge of the steel plate, stepping on the edge, etc.
The existing shear blade side clearance measurement is measured by installing a rotary encoder on the transmission motor shaft of the shear blade clearance adjustment mechanism. The existing side clearance will lead to inaccurate measurement of the side clearance of the cutting blade, and the adjustment of the clearance of the cutting blade is easy to be confused, resulting in the cutting quality of the steel plate not meeting the requirements

Embodiment Construction
[0013] Below in conjunction with accompanying drawing and embodiment this method is described further:
[0014] like figure 1 , figure 2 , image 3 As shown, the disc scissors blade backlash detection device 1 is composed of a displacement sensor 4, a magnetic ring 5, a base 6, a spring 7, a retaining ring 8, a pressure plate 9, a contact rod 10, a pin 11, and a bearing 12. The base 6 is processed by welding steel plates with holes in the middle. The contact rod 10 is installed in the hole on the base 6. There is a groove in the middle of the contact rod 10 to install the pressure plate 9 and the retaining ring 8. The pressure plate 9 is stuck in the groove of the contact rod 10. The bolts between the retaining ring 8 and the pressure plate 9 are fixed. In this way, the pressing plate 9 and the retaining ring 8 will move left and right in the hole of the base following the contact rod 10 . A spring 7 is installed between the retaining ring 8 on the stem 10 and the rib in ...

Disclosed are a side clearance detection device and a detection and adjustment method for a disc shear blade. The detection device consists of a displacement sensor, a magnetic ring, a base, a spring, a retaining ring, a pressure plate, a contact rod, a pin shaft, and a bearing. The bearing is installed on the contact rod through the pin shaft, and the retaining ring is fixed on the contact rod through the pressure plate. The elastic force always presses the bearing on the head of the stem against the side of the upper cutting edge; the magnetic ring is fixed on the end face of the stem. Detection and adjustment method: directly contact the rolling bearing in front of the cutting edge gap measuring device with the side of the upper cutting edge, and keep the lower cutting edge in the axial position to detect the gap between the upper and lower cutting edges; The position of the upper cutting edge can be adjusted to eliminate the gap between the upper cutting edge and the lower cutting edge.
Description
technical field [0001] The invention belongs to the steel rolling technology, and in particular relates to a detection device and a detection adjustment method for a disc shear blade side clearance of a finishing line for wide and thick plates. Background technique [0002] The production and finishing lines of wide and thick plates in rolling mills are basically equipped with rolling-cut disc shears. Disc shears are one of the most important equipment on the finishing line. Its function is to cut the remaining material on both sides of the steel plate to make the two sides of the steel plate flat. The cutting quality of disc shears has a lot to do with the side clearance of the cutting edge. Inaccurate measurement and adjustment of the side clearance of the cutting edge will cause the phenomenon of camber bending, steel plate edge sticking, stepping on the edge and so on. The existing shear blade side clearance measurement is measured by installing a rotary encoder on the ...
