Summary of the invention
The purpose of this utility model is the above-mentioned weak point in order to overcome prior art, and provides a kind of punching simultaneously four parts, and without the no waste mine stock layout Die structure progressive die of punching scrap (bridge).
The technical solution of the utility model is: a kind of no waste mine stock layout Die structure progressive die, and it comprises framework upper bolster, die shoe, die and blanking punch; Upper bolster and die shoe to be led matched moulds by lead, and the bottom of lead is installed on die shoe, and with die shoe interference fit, the top of lead is connected with upper bolster by fairlead; Upper bolster lower surface connection backing plate, punch retainer, discharging rubber and stripper successively from top to bottom, two group leader hole punch and circular hole punch before and after punch retainer is fixing, blanking punch is fixed on the lower surface of upper bolster, the rear of punch retainer; Die is fixed on die shoe upper surface, and both sides, die upper surface connect stock guide, and punch retainer connects side tool, and side tool is positioned at the side of stripper, the front of elongated hole punch.
The further technical scheme of the utility model is: two group leader hole punch and circular hole punch before and after fixing on the left of described punch retainer, also two group leader hole punch and circular hole punch before and after fixing on the right side of it, punch retainer connects two side tools, two side tools lay respectively at the both sides of stripper, the front of elongated hole punch, punch retainer also connects middle cut-out punch, the middle cut-out punch centre that be positioned at two side tools parallel with side tool, the length of middle cut-out punch and side tool is suitable.
The further technical scheme of the utility model is: the lower surface of described stock guide also connects retainer plate, and retainer plate upper surface flushes with die upper surface.
The further technical scheme of the utility model is: described stock guide is provided with seam.
The further technical scheme of the utility model is: the width of described blanking punch is suitable with the width of part, and the length of side tool is suitable with the double-width of part.
The utility model compared with prior art, has following features:
1, part of the upper die is often once descending, and energy punching four parts, significantly enhance productivity.
2, adopt the utility model, billot can not leave scrap (bridge), improves stock utilization.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of no waste mine stock layout Die structure progressive die, it comprises framework upper bolster 1, die shoe 15, die 14 and blanking punch 3, upper bolster 1 and die shoe 15 to be led matched moulds by lead 9, and the bottom of lead 9 is installed on die shoe 15, and with die shoe 15 interference fit, the top of lead 9 is connected with upper bolster 1 by fairlead 7, upper bolster 1 lower surface connection backing plate 2 successively from top to bottom, punch retainer 6, discharging rubber 10 and stripper 12, two group leader hole punch 8 and circular hole punch 5 before and after fixing on the left of punch retainer 6, also two group leader hole punch 8 and circular hole punch 5 before and after fixing on the right side of it, punch retainer 6 also connects two side tools 11, two side tools 11 lay respectively at the both sides of stripper 12, the front of elongated hole punch 8, punch 4 is cut off in the middle of punch retainer 6 connects simultaneously, middle cut-out punch 4 centre that be positioned at two side tools 11 parallel with side tool 11, the middle punch 4 that cuts off is suitable with the length of side tool 11, the width of blanking punch 3 is suitable with the width of part, the length of side tool 11 is suitable with the double-width of part, stock guide 13 is provided with seam 131, its lower surface also connects retainer plate 16, retainer plate 16 upper surface flushes with die 14 upper surface, be positioned at feedstock direction, play the effect of retainer.
Operation principle of the present utility model and using method are: because this product batch is comparatively large, in order to improve output, reducing production cost, adopting less waste material stamping-out, side by side two row, often row two parts, a punch press process four products.First, operator sends billot to, retainer plate 16 and stock guide 13 is utilized to ensure billot rectilinear motion, seam on stock guide 13 131 grades lives billot, part of the upper die is descending, elasticity shedding mechanism (elasticity shedding mechanism is made up of punch retainer 6, discharging rubber 10 and stripper 12) compresses billot, favourable stamping-out, feeding step pitch gone out by two avris cuttves 11, feeding step pitch is the width of twice part, i.e. 24mm, and the middle punch 4 that cuts off cuts off billot, ensure the length 48mm of product simultaneously, billot is divided into two row.Part of the upper die is up, the discharging of patrix elasticity shedding mechanism.Secondly, then send billot to, while completing above-mentioned stamping-out task, go out four elongated holes on product and four circular holes.Then, send billot to again, complete above-mentioned whole stamping-out work, product cuts off by blanking punch 3 simultaneously, and namely two pieces product is discharged from the material-dropping hole of die 14, and another two pieces product stays the upper surface of die 14, and away from feedstock direction, part of the upper die is up.Finally, send billot to, part of the upper die is descending, elasticity shedding mechanism compresses billot, complete simultaneously and go out feeding step pitch, cut off billot, go out four elongated holes, go out four circular holes, cut off product sequence, billot pushes discharge zone the two pieces product staying die 14 upper surface last time simultaneously, and part of the upper die is up, enters next circulation.
The utility model is actually and provides a kind of raising punching efficiency, improves the design of the no waste mine stock layout Die structure progressive die of stock utilization, and provides the concrete structure and way of dealing with problems.
