The application discloses a kind of plate stamping forming springback local coupling control methods, comprising the following steps: according to workpiece structure design workpiece stamping process scheme, using finite element simulation analysis technique analysis and predict workpiece springback amount;According to finite element simulation springback result, draw die surface is compensated for springback;Analysis workpiece occurs large amplitude bending springback area, determine local heating area, in heating device electromagnetic induction heating gun movement path is set;While using local coining method controls bending area springback, coining area is heating area, and grid coining rib is set in the area;In stamping production shaping procedure, local hot forming method and local coining method are simultaneously used to couple control workpiece springback.The springback control method provided by the application solves the problem of large amplitude springback of the product, ensures the quality of the product, and does not need to purchase large heating furnace equipment, reduces the number of die repairing and adjusting, greatly reduces the production cost, and improves the workpiece production efficiency.

The invention discloses automatic production equipment and an automatic production method for an automobile spare tire cover. The automatic production equipment comprises an unwinding and leveling device, a servo feeding and punching device, a forming and edge rolling device, a cutting mechanism and a central control system. The unwinding and leveling device is used for unwinding and leveling the roll-shaped processing material; the servo feeding and punching device is used for receiving the leveled materials, achieving accurate stepping feeding of the materials and synchronously completing punching operation of preset positions. The forming edge rolling device is used for receiving the punched material, extruding and forming the flat-plate-shaped material into an arc section with a preset specification, and then performing edge rolling forming on the flat-plate-shaped material; and the cutting mechanism is used for receiving the rolled and formed material and cutting the rolled and formed material according to the preset length and angle to obtain a spare tire cover finished product. According to the spare tire cover production line, time sequence cooperation of all machining steps and continuous non-offset conveying of materials are achieved, full-process automatic production of spare tire covers from material rolling to finished products is finally achieved, and the production efficiency and the product consistency are improved.
