The shaping for erectting straight flange is dug along certain curve in the edge divided；The master cylinder pressure of hydraulic press is 250KN.
5) shaping, side deburring：Cover plate after punching is put into side deburring shaping compound die, and correction coverplate parts are into accurate
Shape and size.
Further, it is necessary to carry out checking whether its surface gives birth to the mould used in the manufacturing process of the cover plate
Rust, wipes appropriate butter, mould is before using on the machine, it is necessary to check whether the screw gate of mould is tightened, the "T"-shaped groove of mould
Whether the guide pillar of normal mould, guide pin bushing, guide plate are spacing, support it is whether intact；Whether put correctly push rod position.
Further, in the manufacturing process of the cover plate, before the die sinking of upper mould, it is necessary to check mould fixed screw whether
Tighten；Die joint is cleaned with muslin or cleaning agent, to avoid type face from having impurity to damage die joint by pressure, causes product depanning
The bad orders such as garland；After upper mould die sinking die point inspection table must be filled in guide-post of die-set or guide plate oiling.
Further, the cover plate, which repaiies caused waste material in punching and flange, punching operation, needs cleaning in time, avoids giving up
Material accumulation causes burn failure, influences to produce.
Further, require that punching burr meets standard, without deformation, less porous in the flange, punching operation；Punching hair
The 0.3mm being not more than is pierced, the welding location-plate hole punching burr is not more than 0.1mm.
Further, to be tested after the cover plate machines, fill in first inspection record sheet, product piece meets quality
It is required that it can just continue to produce；The self-test frequency：20/time and specially the inspection frequency：200/time.
Beneficial effect
The invention provides a kind of automobile cover plate and its manufacturing process, and compared with existing known technology, of the invention has
Following beneficial effect：
1st, reorganize the technique work flow of cover plate again using compound die, original technique is integrated, subtracted significantly
Processing step is lacked, the processing during cover plate machine-shaping and transhipment time has been shortened, so as to improve production efficiency.
2nd, less technological process, the number of resetting, subtracts when reducing the installation and removal of coverplate parts in a mold
The number that few coverplate parts are transported in processing, so as to effectively ensure the machining accuracy and crudy of coverplate parts.
