Problems solved by technology

This disadvantageously leads to a reduction in the structural space available in the pouch, with consequent loss of capacity and / or having to use thicker or larger pouch cells
[0011] To avoid or reduce the formation of cracks, for example the depth of deep drawing can be reduced, however, this is not desirable for pouch cells with the highest possible capacity
Alternatively, it is possible, for example, to carry out targeted scraping of the plate holder or foil holder, but this involves a considerable amount of time
It is also conceivable, for example, to increase the temperature of the flexible film during forming, but in this case this increases the process costs and reduces the lamination quality
Furthermore, the aluminum content in the pouch can be increased, but this disadvantageously increases the material costs and structural weight of the pouch

Embodiment Construction

[0048] figure 2 A subsequent method step is shown in which the forming tool 6 is closed, ie moved into the closed position. As a result, the soft envelope 8 is clamped and fixed by the compactor 14 and the die 10 .

[0049] exist image 3 In a subsequent method step, the soft envelope 8 is preformed into a preformed bag half 16 ′ by moving the forming die 12 in the direction of the die 10 . image 3 The top dead center position of the forming die 12 is shown here, in which the soft envelope 8 or the preformed bag half 16 ′ rests at least partially on the die 10 . When this dead center position is reached, a step of separating and cutting the bag halves 16 to the target size is preferably carried out at the same time. To this end, the preformed bag halves 16 ′ are separated from the material web of the soft envelope 8 by means of the separating knife 22 . The bag half 16 ′ is a preform which has not yet been completely formed on the female mold of the female mold 10 , espe...

Abstract

The invention relates to a forming tool (6) for deep drawing a soft envelope (8) into a bag half (16) of a soft bag, having a die (10) as a die for the bag half (16) and having a forming die (12) for forming the soft envelope (8) into the die (10), a coil assembly (24) for the magnetic forming of the soft envelope (8) being integrated in the forming die (12).

Description

technical field [0001] The invention relates to a forming tool for deep-drawing a soft envelope into a bag half of a soft bag, having a die as a female mold for the bag half and a forming tool for forming the soft envelope into a die die. The invention also relates to a method for producing a pouch and a device for carrying out the method. Background technique [0002] An electrically or electrically propelled or drivable motor vehicle, such as an electric or hybrid vehicle, usually includes an electric motor with which one or two axles can be driven. To supply electrical energy, the electric motor is usually connected to a (high-voltage) battery inside the vehicle as an electrical energy store. [0003] In particular, an electrochemical battery is to be understood here and below in particular as a so-called secondary battery (secondary battery) of a motor vehicle. In the case of such (secondary) vehicle batteries, the spent chemical energy can be recovered by an electric...
