Description

(54) СПОСОБ УТОЛЩЕНИЯ КРОМОК ЛИСТОВЫХ ЗАГОТОВОК(54) METHOD OF ELIMINATING SHRINES IN SHEETS

1one

Изобретение касаетс  обработки давлением кромок листовых металлических заготовок .The invention relates to the processing of the edges of sheet metal blanks.

Известен способ утолшени  кромок листовых заготовок, при котором производ т их нагрев и осадку. Однако толшина заготовок ограничена, что объ сн етс  малой несущей способностью листового материала при торповом сжатии.A known method of thickening the edges of sheet blanks, in which they are heated and slumped. However, the thickness of the blanks is limited, which is explained by the low bearing capacity of the sheet material under torp compression.

Предлагаемый способ отличаетс  тем, что заготовку перед нагревом гофрируют в направлении, перпендикул рном к направлению последующей осадки, а после утолщени  кромок гофры распр мл ют. Кроме того , одновременно с распр млением гофр производ т калибровку утолщенной кромки.The proposed method is characterized in that the preform is corrugated in the direction perpendicular to the direction of subsequent precipitation before heating, and after the thickening of the edges, the corrugations are straightened. In addition, at the same time as distributing, the corrugations calibrate the thickened edge.

На фиг. 1 дана исходна  листова  заготовка; на фиг. 2 - гофрированна  заготовк на фиг. 3 - гофрированна  заготовка с утолщенной в результате торцовой осадки кромкой; на фиг. 4 - заготовка с утолщенной кромкой после распр млени  гофр.FIG. 1 given initial sheet blank; in fig. 2 - corrugated billet in FIG. 3 - corrugated billet with an edge thickened as a result of end face precipitation; in fig. 4 - billet with a thickened edge after spreading the corrugation.

Заготовку, кромки которой подлежат утолщению, гофрируют в направлении, перпендикул рном к направлению последующей The workpiece, the edges of which are subject to thickening, is crimped in the direction perpendicular to the direction of the subsequent

осадки. Гофрированную заготовку нагревают , и ее кромку осаживают, производ  необходимый набор толщины. После этого производ т распр мление гофр заготовки. Гофрирование заготовки перед осадкой увеличивает несущую способность листа при торцовом сжатии, что позвол ет получить значительное утолшение кромки без опасности потери устойчивости осаживаемого участка.precipitation. The corrugated billet is heated and its edge is precipitated, producing the required set of thickness. After that, the corrugation of the workpiece is distributed. The crimping of the workpiece before the draft increases the sheet bearing capacity during face compression, which allows a significant edge thickening to be obtained without the danger of loss of stability of the deposited area.
