Abstract
A device for bending or levelling workpieces by means of shot peening is improved by controlled impacting and indenting using a support element having a rear wall and side walls; a plurality of force spaced apart distributing elements are arranged in the support element and in the least one layer so that at least some of them abut the rear wall of the support element; a plurality of indenting, shot peening elements in engagement with at least some of the force distributing elements in that any of the shot peening elements engage at least two of the force distributing elements; there are elements of one of the plurality which abut the side walls of the support element.
Claims18
A device for bending or levelling workpieces comprising:
- a support element having a rear wall and side walls;
- a plurality of force distributing elements in the support element arranged in at least one layer so that at least some of them abut the rear wall of the support element, the force distributing elements being spaced from each other to be able to move laterally over spacing between adjacent elements;
- a plurality of indenting, shot peening round, ball or cylindrical elements for engaging the workpieces to be bent or levelled, said indenting elements being in engagement with all of the force distributing elements in that some of the indenting shot peening elements engage at least two of the force distributing elements;
- elements of one of the plurality abutting the side walls of the support element;
- means for retaining the elements in the pluralities in the support element;
- and
- means for applying a pressing force to the support element whereby said force applied to said support element is transferred to said force distributing elements and onto said shot peening elements such that all force distributing elements together act on all shot peening elements as a group.
A device for bending or levelling workpieces comprising:
- a support element having a rear wall and side walls at least one of the walls being movable in plunger like fashion;
- a plurality of force distributing elements in the support element arranged in at least one layer so that at least some of them abut the rear wall of the support element, the force distributing elements being spaced from each other;
- a plurality of indenting, shot peening elements for engaging the workpieces to be bent or levelled, said indenting elements being in engagement with at least some of the force distributing elements in that any of the indenting elements engage at least two of the force distributing elements;
- elements of one of the plurality abutting the side walls of the support element;
- means for retaining the elements in the pluralities in the support element and means for applying a pressing force to the support element, said force applied to said support element is transferred to said force distributing elements and onto said shot peening elements.
A device for working workpieces comprising:
- a first and a second support element each having a rear wall and side walls;
- a plurality of force distributing elements in each of the support elements and arranged in each of them in at least one layer so that at least some of them abut the respective rear wall of the support element, the force distributing elements in each layer being spaced from each other;
- a plurality of indenting, shot peening elements arranged in each support element for engaging the workpieces to be bent or levelled, said indenting elements being in engagement with at least some of the force distributing elements in that any of the indenting elements engage at least two of the respective force distributing elements in the respective support element;
- elements of one of the plurality abutting the side walls of the respective support element;
- means for retaining the elements in the pluralities in the respective support element;
- the support elements being positioned to face each other so as to work on a work piece from opposite sides and means for applying a pressing force to said support elements, said force applied to said support elements being transferred to said force distributing elements and onto said shot peening elements.
