Method and tool device for forming

Abstract

The invention relates to a tool device for forming a section of a body. The device includes at least one moveable retaining device and at least one forming punch moveable in the direction of the retaining device. The section to be formed is arranged between the retaining device and the forming punch. The forming punch during the forming is moved from an initial position into a defined end position relative to the section to be formed. In order to limit the construction space and the forces to be applied, the tool device includes a wedge element which is in contact with the retaining device and/or a die such that a movement of the wedge element effects a movement of the retaining device and/or of the die in the forming direction. Furthermore, a forming method is provided with the aid of the tool device.

1 . A tool device for forming at least one section of a less precisely positioned body by an amount such that the at least one section to be formed lies relative to it the tool device in a more precisely defined position, the tool device comprising:
 at least one movable retaining device and at least one forming punch that is movable in a direction of the retaining device, wherein the at least one section to be formed is arranged between the retaining device and the forming punch, and during the forming the forming punch is brought from an initial position pinto a defined end position relative to the at least one section to be formed; and   a wedge element that is in mating contact with at least one of the retaining device and a die, in such a way that a movement of the wedge element effects a movement of the retaining device and/or of the die in a forming direction.   
   
   
       2 . The tool device according to  claim 1 , wherein the forming punch is fixed to one leg of an essentially L-shaped bracket and another leg is slidably mounted on an end of a base of the tool device. 
   
   
       3 . The tool device according to  claim 2 , wherein the wedge element is formed by a wedge displacer that is guided in the base. 
   
   
       4 . The tool device according to  claim 3 , wherein the wedge displacer is actuated by a cylinder. 
   
   
       5 . The tool device according to  claim 1 , wherein the tool device includes a punching tool. 
   
   
       6 . The tool device according to  claim 1 , further comprising a spring mount is provided between the wedge element and the retaining device and/or the die. 
   
   
       7 . A method for the forming of at least one section on a less precisely positioned body by an amount such that the section to be formed lies in a more precisely defined position relative to the tool device, with aid of the tool device according to  claim 1 . 
   
   
       8 . A method for the forming of at least one section on a less precisely positioned body by an amount such that the section to be formed lies in a more precisely defined position relative to the tool devices comprising:
 positioning of a retaining device on the at least one section to be formed,   forming of the at least one section to be formed by moving a forming punch in a direction of the retaining device, and   displacing of die within the retaining device in a direction of the forming punch with by moving the wedge element, for smoothing of the formed section.   
   
   
       9 . A method comprising:
 positioning of a retaining device with respect to at least one section to be formed, without contact taking place between the retaining device and the at least one section,   Joint displacement of a die and the retaining device with the aid of the by moving a wedge element, until a contact takes place between the retaining device and the die and the at least one section to be formed, and   forming of the at least one section to be formed, by moving a forming punch in a direction of the retaining device against resistance of a spring-mounted die.   
   
   
       10 . The method according to  claim 9 , wherein a subsequent smoothing of the at least one section to be formed is carried out. 
   
   
       11 . The method according to  claim 9 , wherein a stop is formed by the wedge element and the die and/or retaining device, which stop limits the forming of the at least one section to be formed by the forming punch. 
   
   
       12 . The method according to  claim 11 , wherein a punch process is subsequently carried out on the formed section. 
   
   
       13 . A tool comprising:
 at least one retaining device;   at least one forming punch;   a wedge element that is configured to move in mating contact with at least one of the retaining device and a die to effectuate movement of the retaining device and/or the die in a direction towards the at least one forming punch.   
   
   
       14 . The tool according to  claim 13 , wherein the wedge element includes a wedge displacer that is guided in a base. 
   
   
       15 . The tool according to  claim 14 , wherein the wedge element is situated adjacent to correspondingly shaped surfaces facing away the die or the retaining device. 
   
   
       16 . The tool according to  claim 14 , wherein linear movement of the wedge element translates into a movement of the at least one die and the retaining device orthogonal to the linear movement of the wedge. 
   
   
       17 . The tool according to  claim 13 , wherein the wedge element is formed by a wedge displacer moveable inside a stationary base that holds the die and the retaining body. 
   
   
       18 . The tool according to  claim 13 , wherein the wedge element is configured to have a rotatory movement. 
   
   
       19 . The tool according to  claim 13 , further comprising a spring mount provided between the wedge element and the retaining device and/or the die. 
   
   
       20 . The tool according to  claim 13 , wherein the die is a stop for a forming punch during forming
