Operation and safety operation procedures for plate shears
1 The operator must be familiar with the general structure and performance of the equipment, and it is strictly prohibited to use the equipment with super performance.
2 The operator must master the three good and four skills of the equipment used and use and maintain the equipment according to the four requirements of equipment maintenance.
3 Before starting, add grease according to the equipment lubrication regulations, check the oil quantity and quality of the oil cup, and cover the oil cup hole cover.
4 Before work, the upper and lower blades should be aligned first, and the blade clearance should be determined according to the thickness of the shear steel plate, which is generally between 5 and 7% of the thickness of the sheet to be cut. Each time the clearance is adjusted, the flywheel should be turned manually to make the upper and lower blades move back and forth once, and the clearance should be checked with a feeler gauge to see if it is appropriate.
5 According to the requirements of shearing the workpiece, loosen the bolts of the positioning and retaining frame, adjust the size and position of the positioning and retaining plate, and strengthen it. Before operation, it is necessary to conduct a test run for 2~3 times to confirm that the lubrication is good and the operation is normal before operation.
6 It is forbidden to loosen and tighten the retaining device or adjust the blade gap by knocking. When adjusting the guide rail clearance and blade clearance, stop the machine. It is forbidden to enter the shear zone by hand or pick up materials by hand during operation.
7. The blade edge must be kept sharp. If it is damaged, worn or dull, it should be sharpened or replaced in time.
8 When cutting plates of different thickness and materials, the pressure of the pressing plate spring and the clearance of the blade should be adjusted properly to prevent the spring from breaking or damaging the blade.
