Abstract
The utility model provides an annular electromagnetic pulse progressive reverse-deep-drawing forming device for sheet metal. The device comprises a female die driving mechanism, a female die, annular deep-drawing coils, a clamping plate driving mechanism, clamping plates, a bracket, multiple guiding pillars, a male die, a base, at least one boosting coil set and a power system. Electromagnetic force is exerted to push sheets to be formed and the clamping plates downwards; the electromagnetic force is evenly exerted on the peripheries of the sheets to be formed, and the sheets to be formed are horizontally pushed to the center of the female die so that the sheets to be formed can flow into the female die to achieve reverse-deep-drawing forming; downward pressure is exerted to drive the female die to move downwards, so that the sheets to be formed at the bottom of the female die are extruded into the gap between the female die and the male die to achieve reverse-deep-drawing forming; the female die and male die reverse-deep-drawing and electromagnetic pulse deep-drawing are repeated until the reverse-deep-drawing forming is finished. The forming limit and the forming depth of a cylindrical workpiece can be improved substantially.
Description
Technical field
The invention belongs to materials plastic forming field, be specifically related to a kind of progressive reverse drawing and forming device of annular electro magnetic field impulse of sheet metal.
Background technology
In traditional process of sheet forming technique, for avoiding the wrinkling of material, need to adopt blank holder assist formation.The stress-strain state of plate is formed while being illustrated in figure 1 traditional drawing and forming.Flange is subject to radially tension and tangential (circumferencial direction) compression, and radially and is tangentially producing and extending and compression respectively, and thickness of slab slightly increases, and outside flange, edge thickness increases maximum.At die entrance place, material, produces plastic bending simultaneously thickness of slab is reduced pull and stretch except being subject to radially, and material produces back-flexing (alignment) after leaving die entrance, and material is one of easy fracture region herein.It is also one of easy fracture region that cylinder side wall is subject to axial tension.Bottom of cylinder material is in biaxial tension state; At punch-nose angle place, material production plastic bending and radial drawing, this place's material is also easily broken split plot.
Further analysis for above-mentioned plate force-bearing situation is known, in drawing process, blank flange is under circumferential compressive force effect, may produce plastic instability and wrinkling, even make blank can not pass through punch and matrix gap, thereby radially tension is enlarged markedly, when radially tension is greater than the tensile strength of plate, just can produce drawing crack.Although blank holder can avoid material wrinkling to a certain extent, when pressure-pad-force is excessive in order to strengthen drawing depth, can make equally radially tension increase, also can cause plate drawing crack.Therefore, traditional Sheet Metal Forming Technology is the drawing depth of very difficult raising cylindrical member.
Avoid the defect of traditional Sheet Metal Forming Technology, improve the drawing depth of cylindrical member, must improve the mobility of workpiece flange position plate, stress-strain state while changing material forming, reduce radially tension, even change radial compressive stress into, can significantly improve the feasibility that dark barrier part is shaped.
Electromagnetic forming technique has that machining energy is easy to that accurate control, forming speed are fast, Forming Workpiece precision is high, mould is simple and the feature such as equipment interoperability is strong.And whole forming process is green, environmental protection.Now be widely used in the numerous areas such as machinery, electronics, auto industry, light industry and instrument and meter, Aero-Space, weapon industry, application prospect is very wide.Yet, the sheet material electromagnetic pulse forming process of Chinese scholars research at present, main technique is all to stubbornly refuse to allow it produce on the flange section folder of cylindrical member to flow, and the mode of texturing of die part is mainly Bulging Process.It has caused the Thickness Distribution of drip molding inhomogeneous, and Forming depth is more shallow.Therefore, the J.H.Shang of Ohio State Univ-Columbus USA and G.S.Daehn scholar have proposed a kind of improved EMAS forming technique, its basic thought is: the appropriate location that coil is embedded into common diel, in the common punching course of plate, utilize repeatedly little energy electromagnetic pulse electric discharge, improve the formability of material and directly control Strain Distribution, thereby increasing substantially the crystallized ability of material.In order to prove the feasibility of this conception of species, they are embedded into coil the bottom of punch, increase the almost stretching of indeformable cylindrical element base material in traditional pull and stretch, with this, increase the Forming depth of material.Under the identical prerequisite of pressing equipment pressure, the depth capacity that adopts the drawing part of traditional pressing equipment and lubricating oil condition is 44mm, and its depth capacity of workpiece of improved EMAS technology formed thereby can reach 63.5mm.This forming technique is compared with traditional method for drawing, although the drawing depth of cylindrical member increases, but the suffered tension in cylindrical member bottom sharply increases, it is to utilize the attenuate of cylindrical member bottom to improve drawing depth, so the Thickness Distribution of the cylindrical member after being shaped is inhomogeneous, service life is reduced.
As can be seen here, no matter be traditional stamping or this improved EMAS technology, in the process being shaped, the shaping position of plate is all confined to cylindrical member bottom substantially, make the cylindrical member being shaped occur that Thickness Distribution is inhomogeneous, stress collection moderate defect, service life reduces greatly.
