Abstract
The design of the elastic ring compensator of «press-and-die” system errors, the method and software for calculating its geometric parameters are given in the article. The developed method is based on the account of unevenness of the radial and altitudinal deformation (barrel-type shape) of the elastic working element made of polyurethane. A specific example of computer implementation of the developed mathematical model for calculating the sizes of such a compensator for steel-forming operations on an open-crank press is made. Approbation of the compensator was carried out in industrial conditions.
Highlights
The accuracy of “press-and-die” systems are affected from misalignment of the slide axis to press table surface in the loaded state, from distortion in the gaps between press and slide guides, as well as cumulative errors of the punching unit. [1,2,3,4]
The work of the ring compensator can be accompanied by cracking of the elastic plate because during the influence of deformation force the material can flow into non-technological openings, forming regions of increased concentration of stresses and unregulated deformations
The disadvantage of the above-described method is the lack of optimal bonding conditions, which should be determined on the basis of the structural and technological features of the ring compensator and the physical and mechanical characteristics of the glue
Summary
The accuracy of “press-and-die” systems are affected from misalignment of the slide axis to press table surface in the loaded state, from distortion in the gaps between press and slide guides, as well as cumulative errors of the punching unit. [1,2,3,4]. The accuracy of “press-and-die” systems are affected from misalignment of the slide axis to press table surface in the loaded state, from distortion in the gaps between press and slide guides, as well as cumulative errors of the punching unit. Mechanical and elastic compensators are widely used to reduce errors in the “press-and-die” system of opencrank presses and ring compensators of elastomeric materials has not been studied enough. This makes it difficult to calculate their design parameters
