TH9320C3 - Method for enhancing the quality of metal forming parts of the Fine Blanking process by Apply the support set - Google Patents

Abstract

DC60 (July 24, 2014) The process of improving the quality of fine blank metal parts by applying support plates, as described in this invention, involves adding support units to the die assembly. These support units can be separate components and/or a part and/or the entire die and/or press and/or punch. The shape of the support units can be the same as the die and/or press and/or punch, in whole or in part, or any other shape depending on the shape, size, thickness, material type of the workpiece, and/or the die design. This process improves workpiece quality by reducing curvature and resulting in higher quality parts. And/or punch. The shape of the support assembly can resemble the shape of the die and/or the press and/or punch, in whole or in part, and/or any shape depending on the shape, size, thickness, and/or material type of the workpiece and/or the mold design. This process improves workpiece quality by reducing curvature and resulting in higher quality workpieces. (Revised July 24, 2014) The process of improving the quality of metal forming workpieces in the fine blank process by applying support plates, as described in this invention, is done by adding support assemblies to the mold set. The support assembly can be a separate part and/or a part and/or the whole of the die and/or the press and/or punch. The shape of the support assembly can resemble the shape of the die and/or the press and/or punch, in whole or in part, and/or any shape depending on the shape, size, thickness, and/or material type of the workpiece. The type of material required for the workpiece and/or the mold design characteristics can be affected by this process, which allows for improved workpiece quality by reducing curvature and resulting in higher-quality parts.

Claims (1)

The fine blank process for improving the quality of metal forming workpieces using the application of a support system consists of a workpiece press with a jig ring or a workpiece press without a jig ring (1) moving down to press the workpiece (2), then punch 3 moves down onto the workpiece (2) into the die (4) to cause forming. While punch (3) moves down onto the workpiece (2), a counter punch (5) provides force on the movement of punch (3) throughout the punch's pressing motion. For the fine blank process for improving the quality of metal forming workpieces using the application of a support system, it is special because a support system is added to the process. The support system consists of a single side support (7) or it can consist of a side support (7) and a front support (6), depending on the die design. The shape of the front support assembly (6) and the side support assembly (7) will be the same shape as the die (4), workpiece press (1), punch (3), all or part of it, or any shape depending on the shape, size, thickness and type of material of the workpiece (2) required and the design of the mold. (24 Jul 2014) 1. The process of improving the quality of metal forming workpieces in the fine bank process by applying a support set is characterized by a workpiece press with a jig ring or a workpiece press without a jig ring (1) moving down to press the workpiece (2), then a punch (3) moves down onto the workpiece (2) into the die (4) causing forming. While the punch (3) moves down onto the workpiece (2), a counterpunch (5) provides resistance to the movement of the punch (3) throughout the punch's pressing motion. A special feature is the addition of a support set to be used in the fine bank process. The additional support set consists of a support set (8) and/or consists of a front support set (9) and a side support set (10), depending on the die design. The support set (8) has a closed loop shape, with the same shape as the workpiece in whole or in part, while the outer shape can be any shape, depending on the die design. The size of the support assembly (8) depends on the shape, thickness and material type of the workpiece (2) required and the mold design characteristics, as well as the distance A of the punch (3) to the support assembly (8) which depends on the shape, size, thickness and material type of the workpiece (2) required and the mold design characteristics, without causing damage to the support assembly (8) and must have the least possible effect on the quality of the workpiece with rounded sections (7) and the most possible straight sections (6). The support assembly (8) serves to prevent material flow that causes increased compressive stress. The compressive stresses that occur will cause stresses in the shear area and will affect the quality of the workpiece, resulting in the least rounded (7) and the greatest flat (6) shapes. The front support (9) and side support (10) have a non-circular shape and have the same shape as the front and side shapes of the workpiece in whole or in part. The size of the front support (9) and side support (10) depends on the shape, size, thickness and material type of the workpiece (2) required and the mold design characteristics, as well as the distance B of the punch (3) to the front support (9) and the distance C of the punch (3) of the side support (10), which depends on the shape, size, thickness and material type of the workpiece (2) required and the mold design characteristics, without causing damage to the front support (9) and side support (8) and must not affect the quality. The resulting workpiece has the least curvature (7) and the greatest flatness (6). The front support (9) moves down relative to the punch (3), which presses down on the workpiece (2) into the die (4), preventing material flow and thus increasing compressive stress. The side support (10) remains stationary relative to the punch (3), preventing material flow to the sides and thus increasing compressive stress. This compressive stress will affect the stress at the cutting line and will result in the workpiece having the least curvature (7) and the greatest flatness (6).
