Abstract:
L'invention concerne un procédé et une installation de transformation progressive de matériau métallique en bande (25). Ledit procédé comprend les étapes suivantes. On fournit un outil progressif (12) comportant une pluralité de stations de travail (14, 16, 18, 20, 22, 24); on fournit une bande longitudinale (25) d'un matériau métallique présentant une succession de portions de bande (48, 50, 52, 54, 56, 58, 60, 62); et, on entraîne ladite bande (25) à travers ledit outil progressif (12), selon un pas donné, tandis qu'on actionne ledit outil progressif (12) à chaque pas pour que ladite pluralité de stations de travail (14, 16, 18, 20, 22, 24) provoque simultanément la transformation d'une pluralité de portions de bande. On fournit de l'énergie thermique à ladite bande de matériau métallique (25), en amont d'au moins une desdites station de travail de ladite pluralité de stations de travail (14, 16, 18, 20, 22, 24).
Abstract:
A gas spring mount and related method for metal forming dies includes a one-piece, generally U-shaped clamping band with an arcuate medial portion shaped to receive an associated gas spring body therein, and two enlarged ends with through apertures. Threaded mounting screws extend through the through apertures in the clamping band ends, and are anchored into threaded retainer holes in an associated die member. At least one of the mounting screws has a tapered head and is disposed laterally offset from the associated threaded retainer hole in the die, whereby tightening of the one screw shifts the related enlarged end of the mounting band laterally toward the opposite enlarged end to pull the clamping band constrictingly against the gas spring body to securely, yet detachably retain the same therein.

Abstract:
Disclosed herein is die assembly which allows forming sheet metals, which is integrated with the press and capable of performing more than one process at a single stroke of the press in a single section; and a line system which is adapted to said die assembly and comprising a coil feeder, a driver, and a scrap discharging conveyor.
Abstract:
A stock ejector assembly and method for metal forming dies includes a stock ejector with a large spring and a ring-style stripper. The ring-style stripper provides a larger surface area for contacting the stock. The large compression spring is preloaded and when a load is applied, the stripper retracts and the spring pressure increases. When the dies separate, the stock ejector pushes the part off flat surfaces, separating surfaces sealed by adhesion, including, but not limited to, oil or lubricant adhesion.
Abstract:
본 발명은 문틀프레임을 제작하기 위한 금형틀에 관한 것으로, 보다 상세하게는 가공비용과 작업공정을 줄이고, 다양한 형상올 가공할 수 있고 정밀한 제품을 제작할 수 있도록 하였으며 제품을 보다 용이하게 제작할 수 있도록 발명한 것이다. 상기와 같은 목적을 달성하기 위하여 본 발명은 상측에 위치한 금형틀 하나 (상, 하)만 다각형을 유지하도록 하고 나머지 금형틀은 직각을 유지하는 금형틀을 제작하므로 다양한 형상의 문틀생산이 가능하고, 장시간 사용학여도 마모를 줄이고 이에 따라 정밀성을 유지하도록 한 것이다. 또한 문틀의 탈거장치를 제거할 수 있도록 금형의 형상을 단순화하였으며 금형제작비를 절감할 수 있으며 금형형상의 변화로 가공범위를 확대 4고 금형를의 개수 및 가공 공정수를 줄여 생산성을 높이도록 발명한 것이다.
Abstract:
The present invention relates to an improved mechanism for upward lancing in a progressive die assembly. The mechanism comprises plurality of springs means (la&lb), punch means (5), punch actuator means (6), lever means (7), lever actuator means (8), floating insert means (9) and a stripper insert means (10). The lever actuator means (8) is positioned in substantially vertical direction. The lever actuator comprises a collar means (8a), and guide means (8c). The lever means (7) is a substantially oblong shaped which is located on a base plate with a hinged hole (7b). The hinge or pin hole means (7b) is located substantially at center of the lever (7). The lever is provided with a plane elevated portion having a predetermined length substantially at the center of the lever (7). The floating insert means (9) comprises a slot means (9a) and plurality of edges (9b). The slot means (9a) being able to accommodate said spring means (lb). The stripper insert means (10) comprises a slot means (10a) for accommodating and guiding the floating insert means (9).
