Background technology
In mechanical processing industry, metal stamping processing is conventional processing mode, metal stamping be with a metal stamping mould or a series of metal stamping mould be the manufacturing process of the workpiece of three-dimensional dimension shape by metal sheet forming.Metal stamping product is used in various industries, as: automobile, household electrical appliance etc.
Metal stamping die is contained on forcing press, a workpiece of each stroke shaping of forcing press.Punching press can be bending, crimping or shearing, punching etc.
In the time using stamping die punching, in the process of the up material returned of mould, because the rubbing action of workpiece and drift causes drift and workpiece to produce adhesion, when rubbing action is large, cause demoulding difficulty; While rushing multiple hole especially on workpiece, its mold sticking is more obvious simultaneously.
Be illustrated in figure 1 existing a kind of conventional diel, it comprises the fixing fixed head 2 of patrix 1 and its below, is fixed with guide pillar 14 and drift 3 on patrix 1; The counterdie 11 matching with patrix 1, is provided with guide pin bushing 15 and workpiece fixed block 10 corresponding to patrix 1 on it.Workpiece to be processed is placed on workpiece fixed block 10, and a folding of mould realizes punch process one time.But because drift 3 and the adhesion effect of workpiece cause sticking to mould, so can affect quality and the working (machining) efficiency of punch process, in the service life of also simultaneously having reduced pressing equipment, when serious, cannot carry out processing.
Summary of the invention
The object of this invention is to provide a kind of antiseized die stamping mould, realize workpiece and mould normally departs from, prevent that mold sticking from producing, improve quality and the ram efficiency of stamping products, avoid damaging the normal service life of pressing equipment.
For realizing above object, the technical solution used in the present invention is: a kind of antiseized die stamping mould, and it comprises fixing fixed head (2), guide pillar (14) and the drift (3) of patrix (1) and its below; The counterdie (11) matching with patrix (1), with and upper corresponding guide pin bushing (15) and the workpiece fixed block (10) arranging; Described fixed head (2) below is connected with spring dead plate (4) by connecting rod (13), and the upper cover of described connecting rod (13) has spring (12) and itself and spring dead plate (4) to be movably connected; Described spring dead plate (4) center is provided with stripper (9), and side is fixed with elastic draw hook (5) by drag hook fixed block (6); Match with described elastic draw hook (5), on described patrix (1), be provided with drag hook briquetting (7), on described counterdie (11), be provided with hook (8).
Further, on described hook (8), be provided with the briquetting loose slot (802) matching with described drag hook briquetting (7), and the end both sides of briquetting loose slot (802) are provided with retractor head (801).
Further, described elastic draw hook (5) tail end is connected with spring, and front end exposed division has poured in separately oblique angle.
Further, the medial surface of described drag hook briquetting (7) is provided with drag hook loose slot (701).
Beneficial effect of the present invention: a kind of antiseized die stamping mould of the present invention, realize workpiece with mould normally departs from, prevent mold sticking generation; Because having stopped the generation of sticking to mould, improve quality and the ram efficiency of stamping products simultaneously, avoid damaging the normal service life of pressing equipment.

Detailed description of the invention
In order to make those skilled in the art understand better technical scheme of the present invention, describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
As shown in Fig. 2-Fig. 4, concrete structure of the present invention is: it comprises fixing fixed head 2, guide pillar 14 and the drift 3 of patrix 1 and its below; The counterdie 11 matching with patrix 1, with and upper corresponding guide pin bushing 15 and the workpiece fixed block 10 arranging; Described fixed head 2 belows are connected with spring dead plate 4 by connecting rod 13, and on described connecting rod 13, cover has spring 12 and itself and spring dead plate 4 to be movably connected; Described spring dead plate 4 centers are provided with stripper 9, and side is fixed with elastic draw hook 5 by drag hook fixed block 6; Match with described elastic draw hook 5, on described patrix 1, be provided with drag hook briquetting 7, on described counterdie 11, be provided with hook 8.
Preferably, on described hook 8, be provided with the briquetting loose slot 802 matching with described drag hook briquetting 7, and the end both sides of briquetting loose slot 802 are provided with retractor head 801.
Preferably, described elastic draw hook 5 tail ends are connected with spring, and front end exposed division has poured in separately oblique angle.
Preferably, the medial surface of described drag hook briquetting 7 is provided with drag hook loose slot 701.
When concrete use, workpiece to be punched is placed on the workpiece fixed block 10 of counterdie 11 fixing, patrix 1 moves downward under the effect of forcing press, stripper 9 on patrix 1 first contacts compression with workpiece, then the elastic draw hook 5 of spring dead plate 4 both sides tangles the retractor head 801 of the hook 8 of counterdie 11 both sides, and spring dead plate 4 no longer moves downward; Drift 3 on patrix 1 continues descending, and elastic draw hook 5 is in the drag hook loose slot 701 of drag hook briquetting 7 of patrix 1 both sides setting, does not therefore exert an influence to the continuation of patrix 1 is descending, and counterdie 1 downward storke stops, and completes punching press.
When die sinking, patrix 1 moves upward under forcing press effect, because spring dead plate 4 was communicated with extension bar 13 and the spring 12 that overlapping on it is flexibly connected with patrix 1, and it is motionless that the elastic draw hook 5 of spring dead plate 4 two sides tangles the retractor head 801 of hook 8 of counterdie 11 both sides, spring dead plate 4 is not along with movement, therefore under the pressuring action of the stripper 9 below spring dead plate 4, workpiece is not with the up space of drift 3, and drift 3 is forced to separate with workpiece; Patrix 1 continues up, in the time that the drag hook loose slot 701 of drag hook briquetting 7 is up to bottom, drag hook briquetting 7 pushes back elastic draw hook 5 in drag hook fixed block 6, elastic draw hook 5 and the retractor head 801 of hook 8 are departed from, thereby spring dead plate 4 is along with patrix 1 is up, stripper 9 separates with workpiece, takes off workpiece, so completes the whole operations of punching press.
In die sinking, stripper 9 is first not up with patrix 1, pushes down workpiece, and the upstream space of restriction workpiece makes drift 3 first force to depart from workpiece; When drift 3 departs from after workpiece, stripper 9 leaves workpiece with patrix 1 again.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby which key element the process, method, article or the equipment that make to comprise a series of key elements not only comprise, but also comprise other key elements of clearly not listing, or be also included as the intrinsic key element of this process, method, article or equipment.
Applied specific case herein principle of the present invention and embodiment are set forth, the explanation of above example is just for helping to understand method of the present invention and core concept thereof.The above is only the preferred embodiment of the present invention, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be combined by rights; These improve retouching, change or combination, or without improving, the design of invention and technical scheme are directly applied to other occasion, all should be considered as protection scope of the present invention.
