Abstract

The invention provides a one-stop deep-drawing blanking die. The one-stop deep-drawing blanking die comprises an upper die holder and a lower die holder, wherein a female die and a male die which are mutually matched are arranged between the upper die holder and the lower die holder; the section of the male die is convex; the lower-section diameter of the male die is larger than the upper-section diameter of the male die, and the upper-section diameter of the male die is equivalent to the diameter of a product needing to be shaped; and the lower-section diameter of the male die is equivalent to the diameter of the blanking end of the product needing to be shaped. The one-stop deep-drawing blanking die has the following beneficial effects: two processed required by original punching are integrated, so that the punching production process is shortened, and accordingly, not only is the production efficiency of the product improved, but also the production cost of the product is obviously lowered.

Description

One-stop drawing blanking die and its processing method

Technical field

The invention belongs to machine die technical field, and in particular to a kind of one-stop mould for integrating drawing blanking and Its processing method.

Background technology

The product produced in batches using drawing, with high-quality, high uniformity, high leakproofness, high stability and rigidity The features such as.Therefore it is widely used in the fields such as electronics, communication, automobile, machinery, produces in track traffic, Aero-Space, new forms of energy etc. The application in product manufacture field is also widely.More particularly than larger drawing product, present deep-drawing technique be all first under The technique that blanking finally carries out again drawing after material and then drawing, or drawing.But with cost of labor in recent years it is continuous on Rise, big drawing part need it is artificial many, lathe tonnage is big, drawing velocity is low, the high cost of unit jig frequency.So ensureing to produce Quality is constant or even on the premise of being lifted, and needs to find a kind of manufacturing process that can shorten product, reduces the link of manufacture, with This realizes the mould that production improved efficiency is reduced with manufacturing cost.

The content of the invention

The invention provides a kind of one-stop drawing blanking die.

The purpose of the present invention is achieved through the following technical solutions：

One-stop drawing blanking die, including upper bolster and die shoe, are provided with what is cooperated between the upper and lower die holder Punch and matrix, the punch section is in convex, the hypomere of the punch with diameter greater than the punch epimere diameter, the punch Epimere diameter it is suitable with the diameter of required shaped article；The hypomere diameter of the punch is straight with the discharging end of required shaped article Footpath is suitable.

Preferably, the punch is that segmented connects punch, and the punch includes drawing punch and is placed under drawing punch The trimming punch of side.

Preferably, it is threaded connection between the drawing punch and the trimming punch.

Preferably, be from bottom to top disposed with lower bolster, holding pad on the die shoe, the trimming punch with it is described It is threaded connection between lower bolster.

Preferably, the upper bolster is from top to bottom disposed with upper de- in upper padding plate, train wheel bridge and setting and die Plate, be provided between the upper de- plate and upper bolster between contour sleeve, and the upper de- plate and the upper bolster be provided with it is de- Material spring.

Preferably, by positioning dowel pin positioning between the upper and lower die holder, and use is provided between the upper and lower die holder In the guide pillar being oriented to.

Preferably, push rod is provided with the die shoe, one end of the push rod is connected with the holding pad.

Preferably, the processing method of described one-stop drawing blanking die, comprises the steps,

S1, flitch are positioned on drawing punch；

S2, matched moulds, carry out the drawing and forming of flitch；

S3, mould continue to do drawing action, and the outer edge of a knife for driving trimming punch is moved closer to die, as gap constantly subtracts It is little, product is finally cut off, the waste material of cut-out will be stayed on holding pad；

S4, die sinking, push rod carries out de- material step, finally takes out shaped article, completes whole drawing blanking step.

Beneficial effects of the present invention are embodied in：The twice technique that making original punch process needs is focused on together, so as to Punching production process is reduced, the production efficiency of product is so not only increased, the production cost of product has also obtained bright Aobvious reduction.

Specific embodiment

Technical scheme is specifically described with reference to embodiments, present invention is disclosed one-stop drawing blanking die Tool, with reference to shown in Fig. 1-Fig. 2, including upper bolster 1 and die shoe 7, be provided between the upper and lower die holder cooperate it is recessed, Punch.Lower bolster 6, holding pad 5 are from bottom to top disposed with the die shoe 7,

The upper bolster 1 is from top to bottom disposed with upper padding plate 2, train wheel bridge 3 and arranges and the upper de- plate 31 in die, described Upper de- being provided between plate 31 and upper bolster 1 between contour sleeve, and the upper de- plate 31 and the upper bolster 1 is provided with de- material Spring 12.Above structure is similar with cupping tool of the prior art, therefore will not be described in detail herein.

Unlike the prior art, the punch section is in integrally convex, and the punch is that segmented connects punch, Include drawing punch 21 respectively and be placed in the trimming punch 9 of the lower section of drawing punch 21.The drawing punch 21 is convex with the trimming It is threaded connection between mould 9.According to the depth of required product by adjusting between drawing punch 21 and the trimming punch 9 Height is capable of achieving.

The diameter with diameter greater than the drawing punch 21 of the trimming punch 9, i.e., the outer edge of a knife 91 of described trimming punch The outer edge of a knife 22 of the protrusion drawing punch 21.The diameter of the drawing punch 21 is suitable with the diameter of required shaped article；Institute The diameter for stating trimming punch 9 is suitable with the discharging end diameter of required shaped article.The die 5 is tangent with the trimming punch 9.

By positioning dowel pin positioning between the upper and lower die holder, and it is provided between the upper and lower die holder for guiding Guide pillar 51.Push rod 23 is provided with the die shoe 7, one end of the push rod 23 is connected with the holding pad 5.

The operation principle of the lower present invention described briefly below：

Flitch is positioned on drawing punch 21, matched moulds, carries out the drawing and forming of flitch.Mould continues to do drawing action, and driving is cut The outer edge of a knife 91 and the die of side punch is moved closer to, as gap constantly reduces, final cut-out product 8, and the waste material 81 of cut-out will Stay on holding pad 5, die sinking, push rod 23 carries out de- material step, finally takes out shaped article 8, completes whole drawing blanking step. The present invention makes that drawing, blanking are one-stop to be completed, and eliminates the loaded down with trivial details of existing operation, and simple structure is novel, substantially increases production Efficiency.

The present invention still has various specific embodiments.All employing equivalents or equivalent transformation and all skills for being formed Art scheme, all falls within the scope of protection of present invention.
