Device for bending at least one conductor element which is U-shaped in an initial state and which, in an initial state, consists of a first straight limb, a second straight limb and an arcuate connecting portion which connects the two limbs (14, 16), wherein the conductor element is suitable to be inserted into a stator core, wherein the device comprises: - a first pivot unit having a first limb-receiving means which is designed to be pivotable about a first pivot axis on a first circular path and which is designed for clampingly receiving the first limb of the conductor element, - a second pivot unit having a second limb-receiving means which is designed to be pivotable about a second pivot axis, which is arranged in particular at a distance from the first pivot axis, on a second circular path and which is designed for clampingly receiving the second limb of the conductor element, - wherein the first limb-receiving means and the second limb-receiving means can be pivoted away from one another, both in a clockwise or counterclockwise direction, in the same pivoting direction on the respective circular paths, - a guide assembly comprising a first guide element having a first shaping surface and a second guide element having a second shaping surface, - wherein the two guide elements (34, 36) are arranged or can be arranged in such a way that the arcuate connecting portion of a conductor element to be deformed or of a plurality of conductor elements to be deformed and to be arranged one next to the other, in the initial state thereof, can be arranged between the two guide elements (34, 36) in such a way that said conductor elements are guided between the shaping surfaces (35, 37) or can be moved therewith, in particular in the vertical direction, wherein the device comprises a first guide surface, the first guide surface being arranged and designed in such a way that when the first pivot unit is pivoted, a deformed portion of the first limb, which extends from the part of the first limb received in the first limb-receiving means in the direction of the connecting portion, is bent against the first guide surface, so that a contour of the first guide surface is at least partially impressed on the deformed portion of the first limb. - a first pivot unit having a first limb-receiving means which is designed to be pivotable about a first pivot axis on a first circular path and which is designed for clampingly receiving the first limb of the conductor element, - a second pivot unit having a second limb-receiving means which is designed to be pivotable about a second pivot axis, which is arranged in particular at a distance from the first pivot axis, on a second circular path and which is designed for clampingly receiving the second limb of the conductor element, - wherein the first limb-receiving means and the second limb-receiving means can be pivoted away from one another, both in a clockwise or counterclockwise direction, in the same pivoting direction on the respective circular paths, - a guide assembly comprising a first guide element having a first shaping surface and a second guide element having a second shaping surface, - wherein the two guide elements (34, 36) are arranged or can be arranged in such a way that the arcuate connecting portion of a conductor element to be deformed or of a plurality of conductor elements to be deformed and to be arranged one next to the other, in the initial state thereof, can be arranged between the two guide elements (34, 36) in such a way that said conductor elements are guided between the shaping surfaces (35, 37) or can be moved therewith, in particular in the vertical direction,
