1. the chain bending machine for producing the chain with chain link made of being bent as thread elements, comprising:

  • First bending station, with the first bend unit (120- for straight thread elements (200) to be bent into pre-bend thread elements1);

    Control device unit (150), with for grab the pre-bend thread elements and for by the pre-bend thread elements from theThe picking unit (152) into the second position is transported in one position, and the first position is distributed to first bending station, and described theTwo positions are distributed to the second bending station;

    Second bending station, has the second bend unit (120-2) and at least one is used to supply the device of chain link, and described second is curvedFolding unit (120-2) is used to for the pre-bend thread elements being bent into substantial closed thread elements to form chain link, the chainEnergy conservation is enough to be connected thereto when the pre-bend thread elements is bent;

    Wherein, first bend unit (120-1) and second bend unit (120-2) are opposite in vertical machine planeIn offseting each other, first bend unit (120-1) limits the first bending plane extended perpendicular to vertical machine plane(121-1), second bend unit (120-2) limit the second bending plane (121- extended perpendicular to vertical machine plane2), second bending plane (121-2) is positioned at an acute angle with the first bending plane, wherein the acute angle is less than45o
