Abstract
A system and method for manufacturing a metal component, for example a steel or aluminum component for a vehicle, is provided. The system include a plurality of die stations in a production line. One of the die stations includes an upper drawing die and a lower drawing die design to both draw and trim a metal blank, preferably in the same die stroke, to form the metal component having a desired shape. The metal component can be transferred to additional die stations to remove the scrap and for additional processing, such as rough trimming, trimming with a cam, or flanging. Trimming the metal blank during the drawing step can eliminate additional die stations and allows a cam to more easily trim the metal component at another die station.
Claims20
A system for manufacturing a metal component, comprising:
- a plurality of die stations, wherein one of the die stations is designed to perform a drawing or forming and trimming step on a metal blank during a single die stroke
A die station, comprising:
- a first upper drawing die and a first lower drawing die each formed of steel and which are designed to apply a tensile force to the blank and stretch the metal blank;
- the first upper drawing die and first lower drawing die having a shape that forms the metal blank into the shape of a metal component, wherein the metal component is a hood, fender, or door of a vehicle;
- and
- the first upper drawing die including a first upper cutting edge and the first lower drawing die including a first lower cutting edge for together trimming the metal blank while the first upper drawing die and the first lower drawing die apply the tensile force to the metal blank.
A method for manufacturing a metal component, comprising the steps of:
- drawing or forming a metal blank into a shape of a metal component;
- and
- trimming the metal component;
- wherein the drawing or forming and trimming steps are performed at a single die station.
