The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
The DC fan class motor case stretching progressive die as shown in Figure 1, comprises upper die and lower die, in described patrix, towards having a precise cross-shaped guide pillar 1, is provided with the guide hole corresponding with precise cross-shaped guide pillar 1 in counterdie, and described counterdie is also provided with an outer guiding post 2 upward; Described patrix comprises upper cover plate 3, upper bolster 4, upper padding plate 5, train wheel bridge 6, baffle plate 7 and stripper plate 8 from top to bottom successively; Described counterdie comprises lower bolster 9, lower bolster 10, die shoe 11 and lower cushion block 12 from top to bottom successively; Described upper cover plate 3 and upper bolster 4 are installed together, and upper padding plate 5 and train wheel bridge 6 are installed together, and baffle plate 7 and stripper plate 8 are installed together; Wherein, the thickness of described upper cover plate 3, upper padding plate 5, train wheel bridge 6, baffle plate 7 and stripper plate 8 is all less than the thickness of upper bolster 4; The thickness of lower bolster 9, lower bolster 10 and lower cushion block 12 is all less than the thickness of die shoe 11.
The lower surface of described stripper plate 8 is provided with punch part, and the upper surface of lower bolster 9 is provided with the die part corresponding with punch part.
Die part as shown in Figure 2, described die part comprises successively the first blanking die 901, the second blanking die 902, stretching die 903, correcting die 904, pre-punched hole die 905, punching concave die 906, presses bottom outlet burr die 907 and finished product blanking die 908 from the corresponding punch part of feedstock direction; One side of described the first blanking die 901 endoporus is " W " shape, and described die part also comprises some square material guide holes 909; Between described the second blanking die 901 and stretching die 903, be also provided with dual-purpose pin 910.
The corresponding die part of described punch part comprises the first blanking punch, the second blanking punch, stretching convex die, shaping terrace die, pre-punched hole punch, piercing punch, pressure bottom outlet burr punch and finished product blanking punch successively from feedstock direction.
Process of the present utility model is as follows:
When material strip is sent to after mould, by the first blanking punch and formed the first cutting edge of the first blanking die, the both sides on material strip width punch out part arc, then material strip enters a step pitch, by the first blanking punch and formed the first cutting edge of the first blanking die, the both sides on material strip width punch out the outward flange of muscle material scrap (bridge) and the part arc of former and later two workpiece plates, and by the second blanking punch and formed the second cutting edge of the second blanking die, are punched out the part arc of material strip front end; Material strip enters a step pitch again, by the second blanking punch and formed the second cutting edge of the second blanking die, in relevant position, punch out the inward flange of muscle material scrap (bridge) and the part arc of former and later two workpiece plates, through two step blankings, process the die-cut formation of piece material scrap (bridge) " W " shape muscle material scrap (bridge).Then material strip is sent a step pitch again to, by stretching convex die and stretching die stretched part plate, after drawing process completes, material strip is sent a step pitch again to, by shaping terrace die and correcting die, the workpiece after stretching is carried out to Shape correction, after shaping process completes, material strip is sent a step pitch again to, workpiece by pre-punched hole punch and pre-punched hole die after to shaping carries out pre-punched hole processing, after pre-punched hole technique completes, material strip is sent a step pitch again to, by piercing punch and punching concave die, punches out the hole on workpiece; After punching technology completes, material strip is sent a step pitch again to, forces down hole burr process by the workpiece after pressing bottom outlet burr punch and pressing bottom outlet burr die to punching; After forcing down hole burr technique and completing, material strip is sent a step pitch again to, and by finished product blanking punch and the blanking of finished product blanking die, the workpiece of completion of processing (as shown in Figure 3) skids off through stripper, leaves continuous mould.Preferably, workpiece reverse-drawing blanking, the die-cut rear direct whereabouts of workpiece blanking, takes out from mould without source of the gas and aid.
Use the material strip typesetting after the utility model processing, utilize the first cutting edge and the second cutting edge to punch out two workpiece plates that face mutually, and face mutually at two " W " shape muscle material scrap (bridge) that punches out symmetry between the workpiece plate connecing, two are faced the workpiece plate connecing and are connected by " W " shape muscle material scrap (bridge), utilize the piece material scrap (bridge) of the both sides on material strip width to be die-cut into muscle material scrap (bridge), can shorten to greatest extent two distances between workpiece plate, can on same long material strip, produce more product, improve the utilization rate of material strip.
And muscle material scrap (bridge) is to be directly connected on former and later two workpiece plates, the both sides of material strip, without reserving unnecessary scrap (bridge) dowel material scrap (bridge), are used the material strip that width is less just can produce the product of same specification, have effectively saved material.
Mould has precise cross-shaped guide pillar in the process of punching press, guarantees mould good precision and stability in the process of each punching press.
Muscle material scrap (bridge) is " W " shape muscle material scrap (bridge), can strengthen wider space, when stretched part, muscle material scrap (bridge) is out of shape thereupon, makes workpiece stress balance, improve workpiece quality, protection mould, when workpiece enters shaping, pre-punched hole, punching, pressure bottom outlet burr PROCESS FOR TREATMENT, because outer workpiece size does not change, muscle material scrap (bridge) remains former state, guarantees the accurate of step pitch; The eyelet of punching is square in addition, has improved the precision of punching.
The needed material strip reduced width of material strip typesetting after the utility model processing, and before adjacent two workpiece, shorten greatly in the gap of staying, make to produce material therefor and can reduce 20%-35%, reduce production cost, and dwindling of material strip width, makes the tension force bearing of material strip larger, guaranteed that material strip is can be because of the width of material strip in the process stretching not wide and be stuck in two pins, there is the phenomenon getting stuck, improved the stability of material strip processing.
Above-mentioned is enlightenment according to the utility model, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
