Definitions

  • the invention is based on a tool kit for forming bending tools that can be coupled to a tool unit of a bending machine for bending or winding strand-shaped workpieces.
  • a separate tool is usually used for each bending radius and for each shape of the strand-shaped workpiece to be bent (eg., For each wire diameter or pipe diameter o. If the bending radius or the shape of the strand-shaped workpiece to be machined changes, the tool previously used must be replaced by a new tool that corresponds to the new specifications.
  • Such one-piece tools are z. B. in the spring winding machine from the DE 3539730 C2 , in the spring manufacturing device of the DE 10134828 B4 or in the wire bending machine from the DE 19547005 C2 used. These are always conventional, one-piece winding or bending tools with bending mandrel and bending element for a given wire and a certain bending or winding diameter.
  • the object of the invention is to avoid the disadvantages as far as possible and to create a possibility in which the availability of tools for different bending and winding diameter as well as for different forms of treated strand-shaped workpieces associated with significantly lower cost and space requirements is significantly reduced, the need for a change of the complete tool and in most cases a change in the machining specifications for the bending or winding of the strand-shaped workpiece, a significant reduction of the conversion time can be achieved.
  • a tool kit for forming bending tools for bending or winding strand-shaped workpieces that can be coupled to a tool unit of a bending machine, wherein the individual bending tool has a tool holder with a mandrel element and a concentric bending mandrel and a bending element associated therewith, and the tool kit a plurality of tool holders each having a thereto attached mandrel element and a bending mandrel attached thereto, wherein the bending mandrels of the individual mandrel elements have different diameter to each other, and further comprises a plurality of bending elements with mold jaws, each with a forming groove for pressing the strand-shaped workpiece during bending against the bending mandrel are provided, wherein the forming grooves of different mold jaws are designed for each different workpiece cross-sections, and wherein each mandrel element and each of the bending element are each provided with a connecting portion for connection to each other and the connecting portions
  • the inventively provided possibility of training a variety of tools due to the components of a tool kit treads a completely new way in the field of bending or winding tools. It is the first time created by a targeted at least two-part design of each bending tool the possibility for a composition of individual components of a kit. This initially leads to the advantage of a simpler production, since the bending elements and the mandrel (with mandrel element and tool holder) can be made independently, which also advantageously allows the use of different materials for the mandrel element and the bending element.
  • kit includes tool holders with bending mandrels whose diameters cover the most important bending or winding radii, and if the assembly also contains bending elements with shaping jaws for the most important shapes of the strand-shaped workpieces to be machined, the usually required tool variations can be largely covered with such a kit ,

  • each bending element on a mandrel element after applying its connection region against the abutment surface of the latter takes place on this preferably by means of a screw, preferably by means of a countersunk screw, in a radial bore of the bending element.
  • the forming grooves of the forming jaws of the bending elements can be made in a tool kit according to the invention in a variety of forms, in such a way that as many different tool shapes are coverable.
