Specifying perforated skin parameters in manufacturing honeycomb panels of soundproof structures

The article describes the geometric characteristics and features of technology of constructive elements of welded, glued and brazed honeycomb panels used in sound-absorbing constructions channels air intakes and engine casings. Discusses the advantages and disadvantages of various methods for obtaining the perforation drilling electric discharge method: a method of punching sheet at press. Analyse the advantages and disadvantages of each method. In the technique and the dependences for determination of harvesting and the perforation zone boundaries, as well as forming process diagram of perforated paneling. The managing foiling program is developed to meet the geometry, kinematics of the punch press, mechanical characteristics and mathematical model of process of formation. This technique allows you to significantly reduce the number of signs of rejection of the process. One of the most important problems of forming plating method of covering is the uneven distribution of deformations on the surface of the workpiece. To solve this problem, the proposed method of reducing inequality deformation along the contour of the workpiece from the special inserts installed in the press.
