Description
Technical field
The utility model relates to diel field, specifically a kind of dull and stereotyped punching class progressive die.
Background technology
At present, the workpiece application of dull and stereotyped punching class is more, makes also comparatively simply, conventionally adopts compound die to carry out punching press, during due to the punching press of employing compound die, once, production efficiency is lower for feeding of punching press, also has larger potential safety hazard, and workpiece size hour, on workpiece, through hole and Distances Between Neighboring Edge Points are also less, and the concave-convex mold of compound die is owing to being easily subject to the restriction of minimum wall thickness (MINI W.), and inapplicable through-hole spacing, through hole and Distances Between Neighboring Edge Points are compared with the punching press of small workpiece.
Summary of the invention
Technical problem to be solved in the utility model is: the dull and stereotyped punching class progressive die that a kind of production efficiency is higher, potential safety hazard is less, applicability is stronger is provided.
The technical scheme that the utility model adopts is: a kind of dull and stereotyped punching class progressive die is provided, comprise upper die and lower die, described patrix comprises the cope match-plate pattern connecting successively from top to bottom, upper die plate, upper mould fixed plate and stripper, described counterdie comprises the combined die connecting successively from top to bottom, counterdie backing plate and lower bolster, described patrix is provided with the first piercing punch successively from feed end to discharge end, the second piercing punch and workpiece blanking punch, on described combined die, correspondence is provided with the first material-dropping hole, the second material-dropping hole and workpiece material-dropping hole, the first described piercing punch, one end of the second piercing punch and workpiece blanking punch is all located on upper mould fixed plate, the other end all runs through described stripper, described stripper slides up and down connection by stripper bolt and cope match-plate pattern.
The discharge end of described combined die is provided with low inside and high outside inclined plane.
In described upper mould fixed plate, be provided with buffer spring, one end and the upper die plate of buffer spring offset, and the other end and the stripper of buffer spring offset.
Adopt after above structure, the dull and stereotyped punching class of the utility model progressive die is compared with existing compound die, there is following advantage: because the utility model is provided with the first piercing punch, the second piercing punch and workpiece blanking punch, and be provided with corresponding material-dropping hole at combined die, when carrying out punching press, can adopt continuous feeding mode to carry out punching press, the first piercing punch, the second piercing punch can stamp out two holes on workpiece simultaneously, production efficiency improves, corresponding material-dropping hole and discharge end inclined-plane are set and can make the workpiece self-emptying of producing, avoided artificial feeding, potential safety hazard reduces, be not subject to through-hole spacing, the restriction of the punching press of the workpiece that through hole and Distances Between Neighboring Edge Points are less, applicability is stronger.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As Fig. 1, Fig. 2, shown in Fig. 3, the dull and stereotyped punching class of the utility model progressive die, comprise upper die and lower die, patrix comprises the cope match-plate pattern 1 connecting successively from top to bottom, upper die plate 2, upper mould fixed plate 3 and stripper 4, counterdie comprises the combined die 5 connecting successively from top to bottom, counterdie backing plate 6 and lower bolster 7, patrix is provided with the first piercing punch 14 successively from feed end to discharge end, the second piercing punch 13 and workpiece blanking punch 12, on the combined die 5 of counterdie, correspondence is provided with the first material-dropping hole 8, the second material-dropping hole 9 and workpiece material-dropping hole 10, the first piercing punch 14, one end of the second piercing punch 13 and workpiece blanking punch 12 is all located on upper mould fixed plate 3, be, on upper mould fixed plate 3, connecting hole is set, the first piercing punch 14, the second piercing punch 13 is all connected with connecting hole interference fit with workpiece blanking punch 12, the first piercing punch 14, the other end of the second piercing punch 13 and workpiece blanking punch 12 all runs through stripper 4, stripper 4 slides up and down connection by stripper bolt 11 and cope match-plate pattern, namely one end of stripper bolt 11 is connected with stripper 4, the other end slides in the hole of cope match-plate pattern 1 through upper mould fixed plate 3 and upper die plate 2, stripper bolt 11 overcoats have bolt sleeve, the location of stripper bolt 11 is fixed on upper die plate 2 by bolt sleeve.
In this example, the discharge end of combined die 5 is provided with low inside and high outside inclined plane, and namely workpiece material-dropping hole 10 sides are high, and exit side is low, and the setting on this inclined plane can facilitate skidding off of shaping workpiece greatly, is conducive to the feeding of shaping workpiece.In upper mould fixed plate 3, being provided with buffer spring 15, is to be provided with through hole in upper mould fixed plate 3, and buffer spring 15 is located in through hole, and one end of buffer spring 15 and upper die plate 2 offset, and the other end of buffer spring 15 and stripper 4 offset.
The utility model in use, can carry out punching to two workpiece in a punching press of punching station, and arranging of workpiece material-dropping hole 10 and discharge end inclined plane can be avoided artificial feeding, reduces potential safety hazard, increases work efficiency, and the applicability of dull and stereotyped punching class workpiece is stronger.
