The article presents the improved design of the elastic element of the slide direction error compensator. The two-layer elastic element consisting of upper and lower elastic plates of variable thickness is placed between supporting surfaces of the slide and the die upper plate. The joint between the upper and lower plates is stepped The rigidity of this compound elastic element is specified so that at the processing load deformation of the elastic element can not exceed 20-25% of its total height. The optimal value of the horizontal displacement of the upper plate necessary to achieve the necessary rigidity of the elastic element is defined in the article. It has been found that the displacement of the upper plate of of two-layer elastic element should be multiple to the height of the press bed deformation at processing loads. Variable thickness of the compound elastic element may also be used to adjust the interdie space. The processing loads range has been widened as well as the application of the compensator for the «press-and-die» system errors. The proposed design of the compensator elastic element is simple and with minimum of expenses, makes it possible to withstand several million compression cyclesReferences
