HEMMING DATA

Hemming is themethod used to combine metal base part in automotive manufaturing generally .this method is using as an assembly method for closures as door hoods tailgates and truck lid in automotive bodies a compound flanging and hemming die is mountedon a carriage for horizontal movement into and out of allignmentwith the anvilfor successive formation

RELIEF REAR SECTION

The main purpose of the bodywork is to provide accommodation for the driver and passanger with suitable protection against wind and weather the degree of comfort provide depends upon the type of car and its cost the body on the first automotion was little more than a platform with seats attachs 

HINGE

The invention felates to the method and the deveice for installingdoor hinges on car bodies where by the actual opening with of the car door on the side frame receiving one or twomcar doors in the longitudianal car axis 

three kind of hinges are here 

casting hinge

stambing hinges

profile steel hinges

CASTING HINGS

the production precision is relatively higher the volume is samll but hte strngth is high and the weight is relatively larger

STAMBING HINGS

it is a composedof stamoing sheet metal part it is easier to process than casting hinge but is axial strength is good

PROFILE SHEEL HINGE

it is heated by billetrolled into profile steel straightened shot blasted an sawed it is advanced in size an shape

HOOD INNER PANNEL

As an effective approch to reduce the gas comsumption an polution light weight desisn has become an important trent in model car factory due to light density aluminium is the popular alternative material to the conventional steel for automotive applycation which can protectively save 45% of the toatal vechile weight thois may lead to degradation in many dynamic property including structuralmstifness crashworthnes  and noice vibration 

OUTER PANEL

LATCH

A LATCH is a type of mechanical fastener that joins two object on surface wile allowing for their regular seperation a latch typicallyengauge another peice of hardware on the another mounting surface 

REINFORCEMENT 

IN behavioral psychology reinforcement is a conseqence applied that wil strengthen an organism future behaviour whenever that behavior is preceded by specific antecedent stimulus
