Abstract
The utility model discloses a punching bouncing waste prevention device which comprises a backing plate and a lower seat plate. A lower mold knife edge is arranged in the middle of the lower seat plate. Two sides of the lower seat plate are respectively provided with an outer guide sleeve. A resistance sleeve is installed on the outer side of the lower mold knife edge. The periphery of the resistance sleeve is respectively provided with resistance points. A cushion block is installed below the resistance sleeve. A blanking groove is arranged in the cushion block. Craft and design of the lower mold knife edge are enabled to be more reasonable. Jump crumbs are effectively prevented from being generated. In the practical machining process, even a fine knife edge can serve as a clamp point of bouncing waste, and therefore waste is effectively prevented from bouncing. Due to design of the resistance points, molds are free of being smashed in the production process due to extremely large pressure and no more need to be conducted special maintenance, and therefore production stability and safety are ensured. The punching bouncing waste prevention device is novel in design and convenient to popularize and use, and is a good design scheme.
Description
Technical field
The utility model relates to the stamping Die Design manufacture field, particularly relates to the anti-tripping waste device in punching die.
Background technology
Diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc. have direct relation with Design of Dies and manufacturing.The height of Design of Dies and manufacturing technology level is one of important symbol of weighing a national product manufacture level height, is determining to a great extent the development ability of quality, benefit and the new product of product.On the structural design of mould, should guarantee charging as far as possible, surely expect, go out the convenience of part, clear away waste.To forbid other positions of finger, wrist or health of operator to stretch into the operation of mould district for the processing of miniature parts; For the processing of heavy parts, if when the operator must hand enters in the mould operation, reduce as far as possible the scope into mould, shorten as far as possible the time that health a part stops in mould, and should clear and definite mould hazardous area scope, be equipped with necessary safeguard procedures and device.Because the various parts on the mould should have enough intensity and rigidity, prevent from damaging in the use procedure and distortion, fastenings will have anti-loosening measure, avoids the unexpected injury operator.
Yet, for present the most used punching die, although also be designed with the design of anti-tripping waste, great majority are die to be made a flange out block waste material, but in the operating process of reality, because the edge of a knife is very little sometimes, cannot do flange and block waste material, so just do not prevent from jumping the generation of bits, can interrupt so that produce at this point, reduced the efficient of producing, and frequent the safeguarding of needs, Practical Performance is not good, causes using flexibility ratio to reduce, and is unfavorable for promoting and using.
In sum, for the defective of prior art, need especially a kind of punching anti-tripping waste device, to solve the deficiencies in the prior art.
The utility model content
For the generation of jumping bits in the prior art for mould production, and very large defective arranged in the process of practical application, the utility model proposes a kind of punching anti-tripping waste device, simple in structure, easy to make, the tiny like this edge of a knife also can be accomplished the stuck point of preventing material jumping, can effectively prevent from jumping material, promote the efficient of producing, solve the defective of prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of punching anti-tripping waste device, comprise backing plate, lower seat board, the centre of described lower seat board is provided with the counterdie edge of a knife, its both sides are respectively arranged with outer bush, the outside of the counterdie edge of a knife is equipped with the resistance cover, be respectively arranged with the resistance point around the described resistance cover, the below of resistance cover is equipped with cushion block, offers charging conduit above the cushion block.
Further, described resistance point is circular arc, and the quantity of resistance point is four, and resistance point is evenly distributed on the resistance cover.
Further, the thickness of the described counterdie edge of a knife is 2mm, and the thickness of resistance cover is 4mm.
Inboard at outer bush described in the utility model is provided with lead, and a side of lead is equipped with trip bolt.
Between backing plate described in the utility model and lower seat board, feet is installed.
The beneficial effects of the utility model are: this apparatus structure is simple, easy to make, so that the technique of the counterdie edge of a knife and design are more reasonable, can effectively prevent from jumping the generation of bits, in the process of reality, even the tiny edge of a knife also can be done the stuck point of anti-tripping waste, can effectively prevent jump-scrap like this, owing to be designed with the resistance point, so explode owing to pressure is excessive in the not procreative process of mould, and do not need to carry out special maintenance, really precious stability and security of producing, promoted simultaneously the efficient of producing, also effectively save production cost, increased the flexibility of using, modern design, be a kind of good design, be easy to promote and use.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of a kind of punching anti-tripping waste of the utility model device.
Fig. 2 is the resistance nested structure schematic diagram of a kind of punching anti-tripping waste of the utility model device.
100-backing plate among the figure, 110-feet, seat board under the 120-, 130-outer bush, the 140-counterdie edge of a knife, 150-resistance cover, 160-trip bolt, 170-cushion block, 171-charging conduit, 180-lead, 151-resistance point.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to a kind of punching anti-tripping waste of Fig. 1, Fig. 2 device, comprise backing plate 100, lower seat board 120, the centre of described lower seat board 120 is provided with the counterdie edge of a knife 140, its both sides are respectively arranged with outer bush 130, the outside of the counterdie edge of a knife 140 is equipped with resistance cover 150, be respectively arranged with resistance point 151 around the described resistance cover 150, the below of resistance cover 150 is equipped with cushion block 170, offers charging conduit 171 above the cushion block 170.
Present embodiment is in the process of using, in the processing of reality, owing to be provided with resistance point 151 above the resistance cover 150, resistance point 151 is generally done the monolateral resistance of 0.01MM, so just can determine that mould can not exploded, and cushion block 171 is adding man-hour, slow silk to cut one and repaiies three, and the surface is more smooth better.And punching pin will exceed more than the die height 2.5MM, even the tiny counterdie edge of a knife 140 also can be done the stuck point of anti-tripping waste, can effectively prevent jump-scrap like this, with true precious carrying out in order of producing.
