Definitions
- the present invention relates to a method for
- U-profile with a first leg and a second leg and wherein with a second die, the U-profile is formed into an O-profile with a longitudinal flange.
- a method for producing a hollow profile with a longitudinal flange is described for example in DE 10 2005 011 764 AI.
- the known method is in a first bending die by means of a punch in a cross section
- U-shaped profile made with parallel legs.
- Tubular body formed with a closed cross-section.
- legs in at least one of the legs in a longitudinal direction
- Longitudinal flange serves for example for the connection of Body panels. At the dimensional accuracy of hollow profiles ever higher demands are made. This applies in particular to the sections of the hollow profiles with which the hollow sections are connected to other components.
- the present invention therefore has the object of specifying a process-reliable method for producing hollow sections with a longitudinal flange.
- this object is achieved by a method for producing hollow profiles with a longitudinal flange, in soft by inserting a punch in a first die between the S empel and the first die arranged board to a U-profile with a first Leg and a second leg is preformed and with a second die the U-profile to a
- O-profile is formed with a longitudinal flange, wherein the
- a Leksflanschschenkelabsacrificing is formed and the Leksflanschsschenabrough is formed during the molding of the U-profile to an O-profile substantially form presented to a part of the longitudinal flange.
- at least part of the longitudinal length is already formed in the preforming step in which a U-profile is produced, so that the dimensions of a part of the longitudinal flange can be specified precisely.
- the overall dimensional stability of the hollow profile can thus be improved, since in the later Umformschri11en the high dimensional accuracy of the longitudinal flange is no longer explicit
- Retraction according to the invention means that the punch and the first die
- Stamp and die This can be ensured either by a movement of the punch or the first die but also by a movement of both the punch and the first die.
- a first embodiment of the method provides that, at the beginning of the preforming, the longitudinal flange leg section is formed by means of a displaceable partial punch of the punch positioned above the sliding-in retainer, and by further retraction of the punch into the first Gesenk the part punches and the side wall are each moved from the protruding position into a flush position and the board is preformed to the U-profile.
- the position of the board is precisely specified and the risk of warping by a concurrent
- the method can be further developed by using a first die with at least one first displaceable sidewall and the first sidewall in the case of
- Shapes of the U-profile to the O-profile with longitudinal flange by means of the two th die is moved in the retraction.
- the sidewall can laterally support the U-profile during molding to the O-profile with longitudinal flange, so that the process safety of the method can be improved.
- a second die is used, which is a first, the
- Longitudinal flange leg section associated with part die and at least one additional part die includes, and the U-profile is formed to the O-profile by the other part of the die is lowered before the first part of the die.
- process security can be further improved in forming the U-profile to the O-profile.
- Double longitudinal flanges are characterized by an increased rigidity, so that higher forces can be introduced into the hollow profile with them.
- the method can further be characterized in that before forming the U-Prof ils to the O-profile with
- a support core in particular an articulated support core, is introduced into the U-profile.
- Support core can the U-profile during molding to the
- O-profile are supported from the inside and a buckling can be avoided.
- the use of an articulated Support core allows a support even if the U-profile is to be formed into a curved hollow profile.
- an articulated support core also
- the method can also be achieved by shaping the U-profile with the O-profile
- the support core is pulled before or after the cohesive closing. A pulling of the support core before the cohesive closing can the
- a monolithic board a tailored blank or a patchwork blank.
- a monolithic board is understood to be one which consists of a single sheet of a given thickness and a single material.
- Monolithic boards can be special be inexpensively separated from cold or hot tapes.
- "Tailored blanks” refers to blanks that are assembled from individual sheets of different thickness, strength and / or surface coating. As a result, it is possible, on the one hand, to use a thicker and / or even thinner, but also higher-strength material in places with a higher load, so that a lower weight is achieved with a higher load capacity. On the other hand, can be used at the remaining locations on thinner sheets. Tailored blanks thus allow a reduction in weight with the same strength properties.
- motherboards are strengthened locally by attaching individual additional reinforcement plates. Motherboard and reinforcing plates can be easily shaped together afterwards. The laborious and costly
- Tailored blanks are also suitable as baseplates for patchwork blanks, whereby the reinforcing sheets can be used to provide localized reinforcement in a small area, so that individual sheet metal can be used for the blanks
- Tailored blanks a further reduced thickness or another material can be selected.
