Further, punching die of the present utility model, is provided with wearing layer on the madial wall of the second through hole of inserting in die.
Further, punching die of the present utility model, is provided with upper padding plate between upper bolster and punch fixing plate.
Further, punching die of the present utility model, punching die also comprises stripper, stripper is located at punch fixing plate below and is connected with upper bolster.
Compared with prior art the beneficial effects of the utility model are: arrange by said structure, punching die had both been realized the punching to workpiece in a stroke, had completed again the flange to hole, had realized one module multiple usages, had saved manufacturing cost.
Accompanying drawing explanation
Fig. 1 is that the master of punching die of the present utility model looks cutaway view.
In Fig. 1: 1, upper module; 2, lower module; 3, upper bolster; 4, punch fixing plate; 5, punching pin; 6, die shoe; 7, lower bolster; 8, die; 9, cylinder; 10, in die, insert; 11, piston rod; 12, jacking block; 13, punching pin body; 14, punching pin enters piece; 15, control device; 16, spring; 17, guide pillar; 18, guide pin bushing; 19, wearing layer; 20, upper padding plate; 21, stripper; 22, drive unit.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, punching die of the present utility model, comprise module 1 and lower module 2, upper module is fixedly connected with outside drive unit 22, wherein, upper module comprises upper bolster 3, punch fixing plate 4 and punching pin 5, punch fixing plate is arranged on the lower surface of upper bolster, punching pin group is located on punch fixing plate, lower module comprises die shoe 6, be arranged on the lower bolster 7 of die shoe upper surface, be arranged on the die 8 of lower bolster upper surface, also comprise in cylinder 9 and die and insert 10, cylinder along continuous straight runs is arranged on the lateral wall of die, the corresponding position of die and cylinder along continuous straight runs offers groove or the first through hole, the piston rod 11 of cylinder stretches into groove or the first through hole inside, the top of piston rod is connected with can limit the jacking block 12 of inserting and moving downward in die, in die, insert and be provided with the second through hole, the second through hole extends to lower surface from the upper surface of inserting in die, the die cavity madial wall laminating of the lateral wall of inserting in die and die, the bottom of inserting in die is connected with elastic device, the other end of elastic device is connected with die shoe, punching pin comprises the punching pin body 13 matching with the die cavity of die, punching pin body lower end protrudes out punching pin lower surface and is provided with punching pin and enters piece 14, punching pin enters piece and this body by integral forming of punching pin, punching pin enters piece and matches with the second through hole of inserting in die, punching die also comprises control device 15, control device is arranged on die shoe, control device is electrically connected with drive unit, control device is electrically connected with cylinder, stretching of the piston rod of control device control cylinder.
When concrete enforcement, in first jacking block inserts and inserts in die, make must not insert and down move in die, then upper module is down motion under the driving of drive unit, drive also down motion of punching pin, until entering piece, punching pin touches the workpiece that is placed on die upper surface, now going up module continues descending, punching pin enters piece and just workpiece is carried out to punching, until punching completes, when the lower surface of punching pin body touches and inserts in die, control device just sends control signal, the piston rod of control cylinder inwardly shrinks, thereby drive jacking block to be retractable to die inside, now going up module continues descending, punching pin body just punching press has just completed the workpiece of punching operation, thereby workpiece is carried out to overturning process, finally go up module up homing under the driving of drive unit, the control device being electrically connected with drive unit is detecting after this signal to cylinder transmitted signal, the piston rod of control cylinder is protruding, thereby in driving jacking block to insert again to insert in die, limiting it down moves, to treat stroke next time.
Arrange by said structure, punching die had both been realized the punching to workpiece in a stroke, had completed again the flange to hole, had realized one module multiple usages, had saved manufacturing cost.
Preferably, punching die of the present utility model, elastic device is spring 16.The main cause of this design is that spring structure is simple, easy for installation.
Preferably, punching die of the present utility model, die shoe is provided with guide pillar 17, and upper bolster is provided with corresponding guide pin bushing 18.The main purpose of this design is to improve the guiding accuracy of punching die.
Preferably, punching die of the present utility model, is provided with wearing layer 19 on the madial wall of the second through hole of inserting in die.The main purpose of this design is, reduces punch and enters piece lateral wall to the wearing and tearing of inserting the second through hole madial wall in die.
Preferably, punching die of the present utility model, is provided with upper padding plate 20 between upper bolster and punch fixing plate.The main purpose of this design is to reduce the impact between upper bolster and punch fixing plate.
Preferably, punching die of the present utility model, punching die also comprises stripper 21, stripper is located at punch fixing plate below and is connected with upper bolster.Workpiece after the main purpose of this design is the punching press to complete unloads from punching pin, prevents that workpiece from following punching pin and up moving.
Below be only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
