Abstract

Provided is a blanking mould punches a hole. The workshop get used to to use for a long time to be left over the mould that gets off and processes, and very big to the waste of material, the mould also damages easily, it is fast how to overcome abrasion of the die, reduces processor's intensity of labour, is the problem that each mould designer must consider. A blanking mould punches a hole which constitutes and includes: upper die base (b) (b) 3 (b) (b), die holder (b) (b) 10 (b) (b), the upper die base die shank (b) (b) 1 (b) (b) has, the screw (b) (b) 2 (b) (b) of unloading, backing plate (b) (b) 4 (b) (b), fixed plate (b) (b) 5 (b) (b), rubber pad (b) (b) 6 (b) (b) and stripper (b) (b) 7 (b) (b), terrace die (b) (b) A (b) (b) (b) (b) 14 (b) (b) and terrace die (b) (b) B (b) (b) (b) (b) 15 (b) (b) have on the die shank, fixed plate and backing plate are fixed in on the upper die base by screw (b) (b) A (b) (b) (b) (b) 13 (b) (b), shell fragment (b) (b) A (b) (b) (b) (b) 16 (b) (b) has on the stripper, stock guide (b) (b) 8 (b) (b) has on the die holder, hold in the palm flitch (b) (b) 9 (b) (b), die (b) (b) 17 (b) (b), locating piece (b) (b) 18 (b) (b), screw (b) (b) B (b) (b) (b) (b) 11 (b) (b) and shell fragment (b) (b) B (b) (b) (b) (b) 12 (b) (b) have on the stock guide.

Description

Punching blanking mould

technical field:

the utility model relates to a kind of punching blanking mould.

background technology:

workshop long-term habits uses the mould carried over to process, and very large to the waste of material, mould also easily damages, and how to overcome die wear fast, and reducing the labour intensity of processor, is the problem that each Design of Dies personnel must consider.

summary of the invention:

the purpose of this utility model is to provide a kind of punching blanking mould.

above-mentioned object is realized by following technical scheme:

a kind of punching blanking mould, its composition comprises: upper bolster, die shoe, described upper bolster has die shank, unloading bolt, backing plate, fixed head, rubber blanket and stripper, described die shank has punch A and punch B, described fixed head and backing plate are fixed on upper bolster by screw A, described stripper has shell fragment A, described die shoe has stock guide, retainer plate, die, locating piece, described stock guide has screw B and shell fragment B.

described punching blanking mould, is connected with guide pillar between described upper bolster and die shoe.

the beneficial effects of the utility model:

1. the utility model is owing to devising a small-sized shell fragment, solve mould when cutting off billot, part near locating piece place has bullet phenomenon, eliminates the efficiency affecting mould continuous operation, and occurs the hidden danger of the production accident such as burn failure, injury to personnel.

die of the present utility model and base have alignment pin and screw fit when fixing, and ensure accuracy and the fastness of its position.

the utility model, for preventing die deformation excessive, adopts linear cutter, for preventing blanking pressure from causing side force to cross ambassador's crack of die, at the blanking die cavity sharp corner rounding of die.

the utility model is sheet material when stamping-out and discharge process, stressedly also can deform, and causing billot at stepping process generation obstacle, adding elastic tripper, namely ensure that the flatness of workpiece to overcome distortion, turn avoid billot and to advance not smooth factor.

accompanying drawing illustrates:

accompanying drawing 1 is structural representation of the present utility model.

accompanying drawing 2 is Lower die base structure schematic diagrames of the present utility model.

detailed description of the invention:

embodiment 1:

a kind of punching blanking mould, its composition comprises: upper bolster 3, die shoe 10, described upper bolster has die shank 1, unloading bolt 2, backing plate 4, fixed head 5, rubber blanket 6 and stripper 7, described die shank has punch A14 and punch B15, described fixed head and backing plate are fixed on upper bolster by screw A13, described stripper has shell fragment A16, described die shoe has stock guide 8, retainer plate 9, die 17, locating piece 18, described stock guide has screw B11 and shell fragment B12.

embodiment 2:

punching blanking mould according to embodiment 1, is connected with guide pillar 19 between described upper bolster and die shoe, process is: by the upper bolster of mould, on the slide block that die shoe is fixed to punch press and base plate, in adjustment, the shut height of bed die is suitable, billot is advanced to locating piece from stock guide entrance, stock guide has installed alignment pin, ensure that billot and stock guide have certain gap, and elastic conducting materials device is there is also mounted in side, overcome billot that when getting the raw materials ready, billot dimensional tolerance variations brings to advance the problems such as difficulty, thus make the more soft advance freely of feeding, observe the stripper contact billot compressing rubber when slider of punch continues to glide, drive on unloading bolt simultaneously and move, punch is broken through billot and is entered concave die cavity, complete once descending process, when slide block rises, the rubber of compression will resile, pushing bar makes billot still in stock guide, ensure that it is smooth, be beneficial to the beginning of process next time.

Claims

1. a punching blanking mould, its composition comprises: upper bolster, die shoe, it is characterized in that: described upper bolster has die shank, unloading bolt, backing plate, fixed head, rubber blanket and stripper, described die shank has punch A and punch B, described fixed head and backing plate are fixed on upper bolster by screw A, described stripper has shell fragment A, described die shoe has stock guide, retainer plate, die, locating piece, described stock guide has screw B and shell fragment B.

2. punching blanking mould according to claim 1, is characterized in that: be connected with guide pillar between described upper bolster and die shoe.
