Steel cutting machine operation, need to pay attention to what aspects
(1) the shuttle is expected to work surface with lower level of the blade and the length of the table can be determine according to processing material length.
(2) before the start, should check and confirm there is no crack, cutter head bolts, shield. Then turn the pulley by hand, check the gear backlash, adjust the cutting knife gap.
(3) after start-up, should be idle running, check the transmission part and bearing after normal operation before operation.
(4) mechanical fails to reach the normal speed, shall not be cut. Blanking, should be used, the position of the cutter, clenched reinforced on the blade quickly into, the operator should stand at the side of the fixed blade forcibly pressure bar, should prevent the steel bar end pop-up cuts. It is forbidden to hold reinforced with two points on either side of the blade leaning over feeding.
(5) shall not be shear diameter and strength more than machinery nameplate burn the red rules of steel and steel bar. A cutting steel bar, the more the total cross-sectional area shall be within the prescribed scope.
(6) shear low alloy steel, high hardness cutter should be changed, shear diameter should comply with the regulations of machinery nameplate.
(7) cut short material, the distance between the hand and the knife should be kept in more than 150 mm, such as hand side is less than 400 mm, the casing or fixture should be adopted to reinforced short head pressure or clip.
(8) during operation, it is forbidden to remove cutter by hand directly near the severed head and sundry. Steel swing around and around the cutter, can not stay not operation personnel.
(9) is abnormal when found machinery, have abnormal sound or cutter deflection, should immediately stop overhaul.
(10) after operation, cut off the power, steel brush to remove debris between the cutter, on the whole machine cleaning lubrication.
(11) hydraulic transmission type cutting machine work before, should check and confirm the hydraulic oil level and direction of rotation motor meets the requirements. After start-up, should no-load running, open pine oil valve, net of air inside the hydraulic cylinder, before being cut.
(12) manual hydraulic cutting machine before use, oil drain valve should be tighten, clockwise cutting finished, should immediately press anticlockwise unscrew. Job, should hold steady hand cutter, and good wear insulating gloves.
