Abstract
The utility model discloses a finishing mould which comprises a male die and a female die. The male die is externally provided with a fixed plate, the female die is internally provided with a reverse supporting block, a reverse supporting rod is arranged under the reverse supporting block, a female die base plate is arranged under the female die, the reverse supporting rod is inserted into a guide hole on the female die base plate, and the female die is provided with a material guiding chamfer. A finishing method comprises the following steps of: firstly, putting a metal blank between the male die and the female die, and leading some metal blank to enter into a material guiding cavity of the female die partially; and then the metal blank is pressed into the female die by the male die, the reverse supporting block is under the state of reverse supporting pressure at the same time, and the metal blank and the reverse supporting block move downwards under the action of the male die till the reverse supporting block presses against the female die base plate, and the material is filled at the cross section of the blank in a flowing way to form a smooth surface so as to realize the whole finishing process. The finishing mould is simple in structure, good in finishing effect and long in service life.
Description
Technical field
The utility model relates to a kind of metal stock shaping dies, relates in particular to a kind of finishing mold.
Background technology
Along with the development of automobile and electrical equipment industry, blanking part has obtained using very widely.But along with continually developing of punching out kind, numerous parts can not satisfy its final instructions for use fully after simple stamping-out dashes, especially some high-end stamping products, the cross section quality and the angle size of collapsing have also been proposed strict demand, and this finishes the cross section quality and the angle size requirements of collapsing that simple stamping-out does not have realization with regard to needing follow-up technology.
As shown in Figure 1, be the simple stamping-out schematic diagram of workpiece in the prior art.Sheet metal is between holding pad 11 and die 15, sheet material is separating after the plastic deformation under the shear action of punch 12 and die 15 during stamping-out, workpiece 14 moves down the back and leaks down from die 15 die cavities, and waste material 13 utilizes air gun or other servicing units that it is removed on die 15 surfaces.
There is following shortcoming at least in above-mentioned prior art: the one, and workpiece 14 sections that material forms under the effect of punch 12 and die 15 are glossy surfaces in three/part away from punch 12 1 side surfaces only, remainder all is the tear-strap that forms under the effect of pulling force; The 2nd, in the stamping-out process workpiece 14 form the big angle of collapsing away from punch 12 1 side surfaces, form bigger burr in workpiece 14 contact punch 12 1 sides; Influence the service life of mould.
The utility model content
The purpose of this utility model provide a kind of simple in structure, applicability good, the finishing mold of with low cost, long service life.
The purpose of this utility model is achieved through the following technical solutions:
Finishing mold of the present utility model comprises punch, die, and described punch outside is provided with fixed head, and the die cavity inside of described die is provided with anti-jacking block, under the described anti-jacking block anti-push rod is arranged.
The technical scheme that provides by above-mentioned the utility model as can be seen, finishing mold described in the utility model because the die cavity inside of die is provided with anti-jacking block, has anti-push rod under the anti-jacking block.Simple in structure, applicability good, with low cost, long service life.
Description of drawings
Fig. 1 is the structural representation that reaches of simple blanking die of the prior art;
Fig. 2 is the structural representation of finishing mold of the present utility model;
Fig. 3 a-Fig. 3 c is the technical process schematic diagram of finely finishing method of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Finishing mold of the present utility model, its preferable specific embodiment comprise punch 22, die 24 as shown in Figure 2, and punch 22 outsides are provided with fixed head 21, and the die cavity inside of die 24 is provided with anti-jacking block 26, are provided with anti-push rod 25 below the anti-jacking block 26.
Be provided with die backing plate 27 below the die 24, described die backing plate 27 is provided with pilot hole, and described anti-push rod 25 is inserted in the described pilot hole.
The die cavity upper surface of die 24 is provided with the guide chamfering.
In the utility model, die 24 is fixing, and other 2 component shaping power are all adjustable separately, and can be by the program behavior that presets, exert pressure.The concave die cavity upper surface is the guide chamfering, and chamfering size D * 45 ° and blank can be definite according to workpiece kind and thickness with the die clearance C.Metal stock 23 moves down until anti-jacking block 26 under punch 22 effects with anti-jacking block 26 and is pressed against on the die backing plate 27, and material flows and is filled in metal stock 23 sections formation smooth finish surface, realizes whole finishing process.
The utility model adopts novel deformation mechanism, can set up two to compression in the die near closed hollow ring under the situation of using anti-jacking block, thereby realizes the near closed hollow ring finishing, has the workpiece of raising section fineness, reduce the collapse advantage at angle of surface of the work, finishing mold is simple in structure, and is easy to maintenance.
Finishing mold of the present utility model realizes that the method for finishing is:
Shown in Fig. 3 a-Fig. 3 c, comprise step:
At first, metal stock is put between punch and the die, and made metal stock partly enter in the die guide die cavity;
Then, punch is pressed into metal stock in the die, and anti-jacking block is in anti-roof pressure power state simultaneously, and metal stock is pressed against on the die backing plate moving down under the punch effect until anti-jacking block with anti-jacking block, material flows and is filled in blank section formation smooth finish surface, realizes whole finishing process.
Specifically comprise:
A) feeding is about to the guide chamfering place that metal stock 23 is sent into die 24, is in state to be processed.
B) finishing, punch 22 and anti-jacking block 26 are descending until being pressed against on the die backing plate 27, anti-push rod 25 is in the state of pressurize, enter the finishing process, this moment, metal stock 23 was in the near closed hollow ring internal strain that punch 22, anti-jacking block 26 and die 24 form, and made blank 23 outwards fill at section part, formed bright and clean section surface, reduce the angle of collapsing, blank lower surface, thereby obtain good finishing technique effect.
C) material returned is retracted the position on the punch 22, moves on the anti-jacking block 26 and ejects Forming Workpiece 23, and workpiece 23 breaks away from die 24 die cavities and is suspended in anti-jacking block 26 upper surfaces, finishes whole finishing process.
Advantage of the present utility model is, can realize finishing under the situation of using near closed hollow ring.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
