1. after the blanking of the sheet, the chamfering machine must be operated with a chamfering machine or scissors.
2., the line shall be carried out according to the different sizes, shapes and specifications of the air duct. At the same time, the same section of the wind pipe shall be carried out in a complete way to prevent the marking of the wrong holes and materials.
3. 、 the different methods of wind connection, bite connection, rivet connection and welding produced by metal sheet.
4. plate cutting according to the different stages of the line, respectively, and must be reviewed at the same time, so as to avoid errors. Cut by mechanical scissors and hand scissors according to the crossed shapes.
5. when the shear plate gap into mechanical hand is allowed to be placed on the turret, tools and other items, the adjustment sheet, the foot pedal can not be placed in the machine, the use of fixed shear vibration to hands hold the hand from the edge of plate, not less than 5cm, the appropriate uniform force.
6. the width and quantity of the bite are determined according to the thickness of the sheet
7. welding weld must be uniform, no crack and slag phenomenon; rivets, rivet center first perpendicular to the surface of the wood pressing rivet head, the seams are closely combined in order and uniform. Between the plate riveting, generally may not add the padding in the middle, when the design stipulation, follows the design.
8., when the mouth, fingers from the roller shell is not less than 50mm, hands are not allowed in the mouth of the machine to track the stability of the plate.
9, after the bite of the plate, will draw a good square line on the folding square machine, placed in the center line of the lower die, when the operation, so that the mechanical blade center line and the lower die centerline coincide, fold into the required angle.
The 0% off sides should cooperate with each other and keep a certain distance with the folding machine so as not to be upset by the overturned steel plate or fittings.
