In a method for producing an outer panel having a character line, a punch includes a projecting portion for forming a bent surface of the character line at a punch top portion, and a punch shoulder R portion. A contact pressure applied to a blank by at least one of the projecting portion and the punch shoulder R portion is higher than a contact pressure applied to the blank by a remaining portion of the punch which excludes the projecting portion and the punch shoulder R portion. A static friction coefficient of a first portion of the punch which includes at least one of the projecting portion and the punch shoulder R portion with respect to the blank is larger than a static friction coefficient of a second portion of the punch which excludes the first portion with respect to the blank.

The present invention relates to a liquid injection system for a vehicle, including: at least one or more consoles adapted to check a leakage on a vehicle moved along a production line and to supply liquids to the vehicle; and a circulation rail having a working section disposed in parallel with the production line and a pit section in which the consoles are repaired and the liquids are refilled to the consoles, so as to allow the consoles to be circulated along the working section and the pit section thereof. accordingly, the liquid injection system can circulate the consoles using the track type circulation rail, thereby minimizing the time loss generated in liquid injection processes to improve the productivity of the vehicle.

Provided are a low-temperature heat-curable adhesive composition for structures which is able to cure at a low temperature in a short time, is reduced in groove defects after open-state standing, and is excellent in rust-preventive property, corrosion resistance, shower resistance, and workability; and a method for producing an automotive structure using the adhesive composition. The low-temperature heat-curable adhesive composition for structures includes (A) an epoxy resin, (B) a micro-encapsulated curing agent, (C) a hygroscopic agent, (D) a viscosity modifier, and (E) a stabilizer. The hygroscopic agent (C) is calcium oxide, which suitably includes both a surface-treated grade and a non-surface-treated grade.

A wheel nut engagement checking system for a vehicle delivered by a conveyor includes: a moving member disposed at one side of the conveyor; a wheel lifting apparatus disposed on the moving member, and lifting a wheel of the vehicle from the conveyor to a predetermined height; a wheel nut torque checking apparatus provided on an arm of a robot disposed on the moving member, engaging a nut runner to a wheel nut of the wheel, and checking an engage torque of the wheel nut by rotating the nut runner; and a controller controlling a speed of the moving member, lifting the wheel to the predetermined height using the wheel lifting apparatus, moving the wheel nut torque checking apparatus using the robot so as to engage the nut runner to the wheel nut, and detecting an engage torque of the wheel nut by rotating the nut runner.

An assembling method of an electric vehicle comprises the steps of: assembling a vehicle body including a frame, wheels and an electric motor; conducting a vehicle body test including confirmation of a state of driving power transmission from the electric motor to the wheels by connecting an electric power supply unit installed in a vehicle body test place to the electric motor of the vehicle body and supplying electric power from the electric power supply unit to the electric motor; detaching the electric power supply unit from the electric motor and transporting the vehicle body which has passed the vehicle body test from the vehicle body test place to a mounting place, in a state in which a battery is not mounted to the vehicle body; and mounting the battery to the transported vehicle body in the mounting place.

Methods for welding motor vehicle body component subassemblies at a weld stations are disclosed. First and second pallets may be arranged for reciprocal movement between a load/unload station and the weld station and the pallets are alternately moved from a load/unload station to the weld station while the other pallet is moved from the weld station to a load/unload station. Each pallet may have a plurality of substations for receipt of component subassemblies and, while each pallet is at the load/unload station, the component subassembly at each substation is moved to the next successive substation and a further component is added to the moved component.
