Isobaric threaded locking multi-contact rapid forming die

Abstract

The invention discloses rapid forming equipment for plastic deformation processing (such as drawing, undulation and ribbing) of a sheet material. An isobaric threaded locking multi-contact rapid forming die is characterized in that after multi-contact pressing heads of a lower die is used for copying a prototype workpiece, the sheet material receives isobaric pressure applied by multi-contact pressing heads of an upper die, so that the sheet material is forced to deform along the profile of the lower die to produce a product. The isobaric threaded locking multi-contact rapid forming die belongs to the field of material forming and control engineering of mechanology, and comprises a four-guide-post die-set main structure, 1410 contact pressing heads, isobaric seal oil cylinder components, 1410 contact pressing heads and threaded occluded locking devices, wherein the 1410 contact pressing heads and the isobaric seal oil cylinder components are distributed at the upper die in an arrayed manner; the 1410 contact pressing heads and the threaded occluded locking devices are distributed at the lower die in an arrayed manner; and threaded structures are arranged at the tail ends of the 1410 contact pressing heads. When the forming die operates, the lower die obtains a complex inner-profile curved surface that is formed by multiple contacts and is identical with the outer profile of the prototype workpiece, and the multi-contact pressing heads of the upper die act on the upper surface of the sheet in an isobaric manner, so that the sheet material is forced to deform along the inner profile of the lower die, and the product is obtained.

Description

technical field [0001] The invention provides a rapid prototyping device for plastic deformation processing such as deep drawing, undulation, and beading of plates. Specifically, the multi-point indenter of the upper die is used to copy the prototype after the multi-point indenter of the lower die is used. Apply equal pressure to the plate to force the plate to deform along the lower model surface to obtain the product. It belongs to the field of material forming and control engineering of mechanical discipline. Background technique [0002] In modern industrial production and life, various sheet metal parts such as deep drawing, undulation, and beading are common. Each part needs to be produced with a matching mold. If the shape of the part is slightly adjusted, the mold cannot continue to be used. With the acceleration of product upgrading, a large amount of mold cost has been invested, resulting in huge waste, which has become a bottleneck for enterprises to control prod...
