Abstract

El presente invento se relaciona con un mecanismo y un método para formar el estiramiento controlado para impedir que de manera descontrolada seproduzcan estiramientos, arrugamientos o rajaduras de piezas iniciales durante el formado. De manera específica, se provee un mecanismo formador deestiramiento controlado que, de acuerdo con el presente invento, forma y sujeta la pieza inicial entre superficies de matriz enfrentadas y a lo largo deporciones selectivas de la misma; tal sujeción impidela continuación del flujo de material en aquellas áreas durante el resto del proceso de formado. De estamanera, al restringirse la continuación del flujo de material en las áreas elegidas, la porción de la pieza inicial no formada previamente puede serformada entre matrices enfrentadas, sin danar las costuras elegidas o el material de estampe de la pieza inicial.The present invention relates to a mechanism and method of forming controlled stretching to uncontrollably prevent stretching, wrinkling, or cracking of starter parts during forming. Specifically, a controlled stretch forming mechanism is provided that, in accordance with the present invention, forms and grips the blank between facing die surfaces and along selective portions thereof; such clamping prevents the continuation of the material flow in those areas during the rest of the forming process. In this way, by restricting the continuation of the material flow in the chosen areas, the portion of the initial piece not previously formed can be formed between facing dies, without damaging the chosen seams or the stamp material of the initial piece.
