    Abstract: A prediction equation “R0/t?(2R/t+(2R/t+1)?f)/2(1?(1+2R/t)?f)” is derived which predicts that bendability-dominated fracture will not occur when the critical surface strain ?critical is not exceeded by a strain on the metal sheet surface causing the occurrence of ductility-dominated fracture that is obtained from the minimum curvature radius R0 of a press-forming mold and the critical strain ?f in a plane strain region in a forming limit diagram. The minimum curvature radius R0 of a mold required to prevent the occurrence of bendability-dominated fracture is estimated, and the mold is designed with a curvature radius that is not less than the curvature radius R0.

  • Patent number: 9216448
    Abstract: The invention relates to a drawing press (10) having a first ram (17) and a second ram (18). The first ram (17) is moved in a working direction (A) by an electromotive first ram drive (25) and the second ram (18) by an electromotive second ram drive. The drawing press (10) also has a coupling means (35) which can be switched between an uncoupling state and a coupling state. In the uncoupling state, the two rams (17), (18) can move independently of one another in the working direction (A). In the coupling state, the coupling means (35) ensures that a relative movement between the two rams (17, 18) is prevented. The drawing press (10) can therefore be operated as a single-acting or double -acting press.

The method includes a level difference formation step that moves a second portion, which is positioned on the inner peripheral side of a first portion in a radial direction of a disc-like blank, relative to the first portion in a first direction which is the thickness direction of the blank, thus forming a level difference between the first portion and the second portion. A conical portion formation step moves the second portion relative to the first portion in a second direction opposite to the first direction, eliminating the level difference. In this manner, a conical portion is formed in the second direction on the inner side of the second portion; and a burring step performs a burring process on the conical portion, thus forming the boss portion.

  • Publication number: 20140212683
    Abstract: The invention relates to a method for producing a cup-shaped body (1), the edge (2) of which has a flange (3) and extends in a plane (E) which is inclined to a plane (F) which is perpendicular to the direction of the axial extension (L) of the cup-shaped body (1). For a simple, cost-efficient and reliable production, the method comprises the steps: Producing a hollow body (5) by way of a deep-drawing process, and a circumferential shoulder (7) is formed in the shell (6) of the hollow body (5), which shoulder (7) extends between two shell sections (8, 9) and extends in a plane which is inclined to a plane which is perpendicular to the deep-drawing direction (R) of the deep-drawing process, and cutting the hollow body (5) along the shoulder (7) in order to obtain the cup-shaped body (1), with the flange (3) of the cup-shaped body (1) being formed by at least one part of the shoulder (7).

  • Patent number: 8789403
    Abstract: A can bodymaker and a method of forming different sizes of drawn and wall ironed cans from the same bodymaker, in which the bodymaker includes a ram (4), a crank (22), first and second connecting rods (21, 23) and a swing lever (20) connecting the crankshaft (22) to the ram (4). Different locking positions (X, Z) are provided on the swing lever so that the first (primary) connecting rod is connected to alternative positions on the swing lever. The primary connecting rod (21) then rotates about an axis between the selected locking position and position (Y) of pivot pin 30 on the swing lever (20). The primary connecting rod drives the swing lever to rotate by a corresponding degree, and thereby converts the swing lever rotation into axial movement of the ram (4) so as to move the ram by a specific stroke length. By altering the locking pin (25) position and therefore the pivot point for the primary connecting rod, the stroke of the ram is changed.

    Abstract: A cylinder guard for a deadbolt lock having a face portion and an inner portion. The inner portion includes a radial flange and an axial flange created by forming the wall of the guard into a doubled portion. Indentations are formed in the axial flange which enhances the resistance of the guard to an attack upon the deadbolt. The guard also includes a tapered blow-deflecting portion between the inner portion and face portion. A crush zone may be formed between the inner and face portions to attenuate the energy from an attack that is transferred to the axial and radial flanges. A method for making the guard includes stamping a body from steel strip using a multi-station press.

  • Publication number: 20140047892
    Abstract: The invention relates to a drawing press (10) having a first ram (17) and a second ram (18). The first ram (17) is moved in a working direction (A) by an electromotive first ram drive (25) and he second ram (18) by an electromotive second ram drive. The drawing press (10) also has a coupling means (35) which can be switched between an uncoupling state and a coupling state. In the uncoupling state, the two rams (17), (18) can move independently of one another in the working direction (A). In the coupling state, the coupling means (35) ensures that a relative movement between the two rams (17, 18) is prevented. The drawing press (10) can therefore be operated as a single-acting or double-acting press.
