Embodiment Construction

[0033] Figure 1 shows a method for producing a highly dimensionally stable bearing shell according to the prior art. In a first step 2 , the plate 4 is deep drawn in a first die 6 . After the deep-drawing process 2 , the bearing shell 8 produced in this way has a dimensionally stable tip 10 which reduces the preformed bearing shell 8 . In a next step 12 , the tip 10 is removed by cutting the bearing shell 8 . This process can either be carried out in another tool or integrated in the first deep drawing process 2 . After the final cut 12, the frame area of ​​the flangeless bearing shell 14 has the desired target height. As a result of the deep-drawing process 2 , the bearing shell 14 has dimensional inaccuracies that can be removed in the subsequent final forming 16 by means of the calibration tool 18 . Finally, a highly dimensionally stable bearing shell 20 is produced in this way. The disadvantage of this method is that, since the cutting 12 prolongs the process chain for...

Abstract

The invention relates to a method for producing highly dimensionally stable half shells from a cut board, wherein the half shell is pre-formed by deep-drawing in a first die (28, 46), optionally using at least one hold-down (56), wherein the first die (28, 46) has at least one stamp (48), one die floor (50), one die supporting surface (52) and a frame region and wherein the pre-formed half shell (30, 60) is then finally formed in a second die (34, 62), particularly in a calibration tool. In addition, the invention relates to a device for producing a half shell. The problem of specifying a method which simplifies the production of highly dimensionally stable half shells is solved in that the board is cut having a positive dimensional deviation in the specified tolerance range, in consideration of the desired final form of the pre-formed and finally formed half shell, before deep-drawing, the die floor (50) of the first die (28, 46) is moved relative to the die supporting surface (52), the board is clamped between the die floor (50) and the stamp (48) of the first die (28, 46) and the board is guided in being deep-drawn.

Description

technical field [0001] The invention relates to a method for producing a highly dimensionally stable bearing shell from a cut sheet, wherein the bearing shell is preformed by deep drawing, optionally using at least one hold-down device, in a first mold, wherein the first mold has at least one die, die Bottom, mold support surface and frame area, and wherein the preformed bearing shell is subsequently finally formed in a second mold, in particular in a calibration tool. The invention also relates to a device for producing bearing shells. Background technique [0002] It is known in the prior art to produce tall, dimensionally stable bearing shells by deep-drawing sheet metal. [0003] It is known, for example, from DE 10 2007 059 251 A to produce highly dimensionally stable bearing shells in a two-step process. Firstly, a preformed bearing shell is produced that has residual material over the entire cross section due to the geometry. Next, the preformed bearing shell is up...
