20100294014 | Process and apparatus for producing a hollow body, and hollow body - A process for producing a metal hollow body comprising a first axial portion with a first cross-sectional area and a second axial portion with a second cross-sectional area, and in which the two axial portions are connected to one another by means of a shape transition running in the axial direction, the method includes producing a preform body having at least one transition region which extends in the axial direction and is arranged between the first and second axial portions, wherein, in the transition region, the cross-sectional area of the preform body continuously changes from the cross-sectional area of the first axial portion into the cross-sectional area of the second axial portion, accommodating the preform body in a die, a shaping mandrel into the preform body, and axially moving the shaping mandrel to upset the preform body in the die into the final shape of the hollow body. | 11-25-2010 |
20110088443 | Supporting Core for Producing Hollow Profiled Elements - A supporting core for using in a device for forming plates into a structured hollow profile and a method for producing structured hollow profiles from a plate, which on the one hand ensures an all-over support of the plate, and still enables the production of hollow profiles with a variable cross-section or a curved course, is provided by including individual supporting members, which when pushed together at least in part form as a surface an inner contour of the hollow profile to be produced and are interconnected by means of coupling elements, wherein the coupling elements allow the supporting members to be pulled-apart, and wherein the supporting members are interconnected in a hinged manner in the pulled-apart position. | 04-21-2011 |
20130091919 | Method for Producing Hollow Profiles Having a Longitudinal Flange - The invention relates to a method for producing hollow profile-members having a longitudinal flange, wherein a plate which is arranged between the stamp and the first die being preshaped by introducing a stamp into a first die to form an U-shaped profile-member having a first member and a second member, and wherein the U-shaped profile-member being shaped with a second die to form an O-shaped profile-member having a longitudinal flange. In one aspect, the plate is preshaped to form the U-shaped profile-member, a longitudinal flange member portion is shaped in at least the first member and the longitudinal flange member portion is constructed during the shaping of the U-shaped profile-member to form an O-shaped profile-member substantially in a shape-retaining manner to form a portion of the longitudinal flange. | 04-18-2013 |
20140060281 | METHOD AND DEVICE FOR MECHANICALLY REMOVING COATINGS FROM COATED BLANKS USING A PRESS AND SCRAPING KNIFE - The invention relates to a method for the decoating at least in part of blanks made of metal which are coated on one or both sides in regions, which have a main extension direction, wherein the regions to be decoated can extend in both a straight or curved manner in the main extension direction. The invention further relates to a device for the decoating at least in part of a coated blank in order to carry out the method according to the invention. A method is provided in which the blank is placed on a blank support of a press and during the closing movement of the press at least one scraping knife preferably completely removes the coating of the blank by scraping substantially perpendicular to the main extension direction of the region of the blank to be decoated. | 03-06-2014 |
20160024605 | Method for Producing a Profile and a Manufacturing System for Producing a Profile - A method for producing a profile includes method steps of: providing a workpiece; shaping the workpiece; joining the workpiece; coating the workpiece; heating the workpiece; and at least partially hardening the workpiece; wherein the coating method step is carried out temporally after the joining method step and temporally before the heating method step. | 01-28-2016 |
20160052037 | METHOD FOR PRODUCING HIGHLY DIMENSIONALLY ACCURATE HALF-SHELLS AND APPARATUS FOR PRODUCING A HALF-SHELL - The invention relates to a method for producing highly dimensionally accurate half-shells from a tailored blank, wherein, in a first die, with optional use of at least one hold-down means, the half-shell is subjected to pre-shaping by deep drawing, wherein the first die has at least one punch, a die base, a die rest surface and a jacket region, and wherein the pre-shaped half-shell is subsequently subjected to final shaping in a second die, in particular in a calibration tool. The object of specifying a method which simplifies the production of highly dimensionally accurate half-shells is achieved in that, before the deep drawing, the blank is tailored by cutting, taking into consideration the desired final shape of the pre-shaped and/or finally shaped half-shell, with a positive dimensional deviation in the predefined tolerance range, the die base of the first die is moved relative to the die rest surface, the blank is clamped between the die base and the punch of the first die, and the blank is deep-drawn in a guided manner. | 02-25-2016 |
20160068921 | METHOD AND TOOL FOR HARDENING A HOLLOW PROFILE OF A STEEL WORKPIECE - Disclosed herein is a method and tool for hardening a hollow profile of a steel workpiece having an interior space. The method includes the steps of providing a workpiece having a hollow profile, heating the hollow profile, placing the hollow profile of the steel workpiece in a hardening tool, and cooling the hollow profile from the inside by way of a cooling core having an exterior shape that is complimentary to that of the structural shape of the interior space of the hollow profile. | 03-10-2016 |
20160101456 | METHOD AND DEVICE FOR PRODUCING A SHAPED COMPONENT - Example methods and devices for producing a shaped component may involve positioning a workpiece having a hollow region and consisting at least partially of steel in a mold of a device. One or more docking punches may secure the workpiece within the mold and serve to introduce a pressurized fluid into the hollow region of the workpiece within the mold. The workpiece may be hot-formed in this process. The present disclosure concerns a variety of methods and devices that may be utilized to counteract a cooling of the workpiece in a region of the docking punch and reduce a temperature difference that may exist between the workpiece and the device. | 04-14-2016 |
