Design of backdoor

BACK DOOR DESIGN

Before designing the back door we have to consider some design consideration

1. Rear visibility 
2. Support Structures like hinges and Gas stay
3. Rear crash Regulation
4. Boot space
5. Mountings
6. Draftg Analysis

Before going to the design 

First we have check any irreguarites are there in given skin data we have repair the surfaces which are not proper after that we have proceed with design of back door.

Design of sealing flange

Tooling direction

The tooling direction is while manufacuring the design .The back door is manufactured by using deep drawing process.The tooling direction is given to move the core in a straignt path.

Connecting flange

Latch and Striker Trajectory

Outer panel Lower

Hemming

Hems are folds to the edge of a part to create a rounded, safe edge. Hems may be open, flat, or tear-dropped, and tolerances depend on the hem’s radius, material  thickness, and features near the hem. The process of creating hems is called hemming.

 Side relief

The side relisf are created to reduce unwanted deformation during any sheet metal process.

Reinforcement

1.Hinge reinforcement

2.Gas stay reinforcement

3.Wiper motor reinforcement

4.Latch Striker reinforcement

Draft Analysis

Draft analysis is done to analyse the draft angle.While manufacturing the part the tool should come out properly without any Bending inside the sheet metal.
