Embodiment 2

The present embodiment provides a kind of technological process of the integrated automatic fixture of progressive die of nutplate part, specifically includes：

(1) blanking die

The blanking die is the process of progressive die first, is fixed on cushion plate of pressing machine, is punched according to parts profile, simultaneously Locations of contours is subsequently being carried out using profile is punched out.Depending on deburring shape is according to shape of product, deburring insert material is SKD11.After deburring is carried out to plate, the detent mechanism that can be stretched in the plate both sides trim position use of upper and lower mould respectively Whole plate is positioned.In mold work, detent mechanism is deep into plate indentation, there and positioned；Carried out in progressive die When sending and (walk) material automatically, detent mechanism is withdrawn, and the advance of plate is not influenceed.To ensure three blank operations and the process of drawing first Stable, mould is fixed on the mounting plate that a stock material is 45# steel in this four processes, and this mounting plate is fixed on and is connected to On the switch base plate of lathe upper mounting plate.The lower mould of this same four sequence is also fixed on the bottom plate that a stock material is 45# steel, and This backing plate, which is fixed on, to be connected on the bottom plate of lathe lower platform.

(2) draw forming die

The draw forming die is second process of progressive die, is fixed on cushion plate of pressing machine, is moved with press, should Section includes 10 sequence drawing operations altogether.Upper mould is moved downward, and is first contacted with the cylindrical binder part of lower mould, is carried out binder, Ran Housui Mould continue move downward, and lower mould (cavity plate) contact, formed cylindrical protrusions.Here binder part is in process After drawing operation terminates, the effect for raising plate is also acted as during lifting, so as to realize self-feeding.First drawing operation To be cylinder flat board drawing, plate is flow to cylinder recessed by follow-up drawing operation to reduce round diameter and cylinder height At mould fillet.Except first time drawing operation and preamble blanking die are in first piece of small raft, remaining 9 sequence drawing die is pacified for guarantee Conveniently, stably, every three sequences drawing die is set to be installed on the backing plate that a stock material is 45# steel dress.Last three process, to drawing essence Degree requires to improve, and is oriented on the backing plate that last three sequences drawing die is installed using ф 25 guide pillar.In the first sequence drawing After the completion of have a sequence idle station.Mould is punch-pin on drawing die, and it is feeding pressure mechanism, material in the middle of mould under SKD11, drawing die that material, which is, For SKD11, lower mould material is also SKD11.In drawing process, punch-pin first and lower molding compound mechanism contacts, then punch-pin and recessed Contour forming.It can be seen that ten drawing operations, in the case where meeting material processability, constantly reduce drawing area of section (body diameter), to meet the requirement of this wall of forging ordered pair.The process number of drawing operation and each ordered pair body diameter subtract A small amount of is all that, by repetition test, can meet follow-up work content, and can finally meet the requirement of product.It is complete in drawing Cheng Hou, lower molding compound mechanism jack-up in the presence of nitrogen cylinder, plays a part of ejector, so as to realize plate in self-feeding Advance under mechanism effect.

(3) punching die

The punching die is fixed on same cushion plate of pressing machine, is moved with press, in column top according to nut Crab bolt size is punched out, while there is waste material slide-down mechanism to slide the waste material produced by punching in mould bottom；

(4) upset mould is forged

The forging mold is fixed on same cushion plate of pressing machine, is moved with press, and upper mould is punch-pin, with press Move downward, lower mould is cavity plate, upset to being carried out at part wall and die entrance, this content includes 5 sequence forging molds altogether, makes Obtain part wall diameter and reduce wall thickness increase；Specially：Upper mould carries out upset shaping to the part for being positioned over lower mould, and upper mould is with The material of mould is all SKD11.To ensure the stabilization of upset process, it is slow that we are mounted with that nitrogen spring is made between upper and lower mould Rush device, the bottom surface of nitrogen spring is fixed on die shoe, upper end act on upper bolster with high block.By constantly testing, pier The body diameter of unskilled workman's sequence constantly diminishes, and the wall of cylinder is constantly thickened.This is to meet the next step tapping stage to reach Form.Because different part materials are different with required nut size, it can be seen that reserved idle station, it ensure that enough Forging process meet different parts to forge sequence demand.

(5) blanking die

The blanking die is moved with press, and part is punched according to part shape；First in the middle of part Position punching.Specifically, drift is fixed on mould, material is SKD11, and die case and scrap material slideway are in lower mould.This hole is follow-up The positioning hole of deburring sequence part.Then two-step is to carry out deburring according to product profile.Deburring insert material is SKD11.To protect Demonstrate,prove punching, trimming process step it is accurate, stably, set on the backing plate that these three process moulds are installed four ф 25 guide pillar in Corner is oriented to.Meanwhile, set seven buffers to be uniformly distributed in working region, punching and trimming process step is more stablized.

(6) tapper mechanism

The tapper mechanism is moved with press and is accurately oriented to guide pillar, and this tapper mechanism is integrated in progressive die In move, work and cooled down using coolant with press；

(7) shaping dies

The shaping dies is moved with press, and the shape in nutplate is formed；According to product requirement to zero Part locally carries out shaping.Shaping dies material is SKD11, and the material of deburring cutter block is also SKD11.To ensure shaping and knife edge die Have work accurately, stably, used four guide pillars to be oriented to punching and cut off operation in corner, and uniformly placed six Individual nitrogen spring buffer stablizes punching course.The bottom surface of nitrogen spring is fixed on die shoe, and upper end acts on upper bolster With on high block.

(8) mould is cut off

The cut-out mould is also fixed on cushion plate of pressing machine, is moved with press and part is cut off, cut-out Part can be slided into tote-box along slideway.Waste material can also be slipped to garbage collection area along slideway.

It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not This is confined to, any one skilled in the art is in the technical scope that the utility model is disclosed, according to this practicality New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model Within enclosing.
