Abstract

It the utility model is related to a kind of punching anti-scrap bouncing lower die edge of a knife, including lower die cutter hub, the material-dropping hole that the lower die cutter hub is equipped with straight knife hole and is arranged on below the straight knife hole and is penetrated through with the straight knife hole;The material-dropping hole is with tapered hole, and it is raised that anti-scrap bouncing is equipped with the tapered hole.The utility model is simple in structure, and manufacture cost is low, and punch downlink is punched tablet during work, and punch enters inside the edge of a knife, is produced after punching after waste material driven into material-dropping hole by punch, and anti-scrap bouncing is raised interacts, and is stuck in anti-scrap bouncing protrusion;When punch travels upward and out waste material, waste material can be not easy to stir and cause jump to be considered to be worth doing, considered to be worth doing so as to effectively prevent from jumping because being stuck in anti-scrap bouncing protrusion, it is ensured that the stability and security of production, while improve the efficiency of production.

Description

A kind of punching anti-scrap bouncing lower die edge of a knife
Technical field
It the utility model is related to a kind of edge of a knife, and in particular to a kind of punching anti-scrap bouncing lower die edge of a knife, belongs to lithium battery accessory Processing mold technical field.
Background technology
Stamping die is the essential technological equipment of punching production, is technology-intensive product.The quality of stamping parts, life Efficiency and production cost etc. are produced, has direct relation with mold design and manufacture.The height of Mould design and manufacturing technical merit, It is the one of the important signs that for weighing a national product manufacture level height, largely decides quality, the effect of product The development ability of benefit and new product.Should try one's best the side for ensureing charging, expecting calmly, going out part, clear away waste in the structure design of mould Just.Processing for miniature parts will forbid other positions of the finger of operator, wrist or body to stretch into the operation of mould area;For The processing of heavy parts, if operator must hand when entering operation in mould, to reduce the scope into mould as far as possible, shorten body as far as possible Body a part residence time in mould, and should be understood that mould hazardous area scope, it is equipped with necessary safeguard procedures and device.Due to Various parts on mould should have enough intensity and rigidity, prevent damage and deformation during use, fastenings will have anti- Loosening measure, avoids unexpected injury operator.
However, for punching die the most used at present, it is most of to be although being also configured with the design of anti-tripping waste Cavity plate is made into a flange and out blocks waste material, but in actual operating process, due to edge of a knife very little sometimes, cannot done Flange blocks waste material, does not prevent from thus jumping the generation considered to be worth doing so that and production with regard to this interruption, can reduce the efficiency of production, and And need it is frequent safeguard, practical performance is bad, causes the reduction of using flexible degree, is unfavorable for promoting and uses.
Utility model content
The utility model is the defects of overcoming the prior art, and the utility model aim is to provide for one kind can be effective Prevent from jumping and expect, lift the punching anti-scrap bouncing lower die edge of a knife of the efficiency of production
The technical solution adopted in the utility model is:A kind of punching anti-scrap bouncing lower die edge of a knife, including lower die cutter hub, under described The material-dropping hole that mould cutter hub is equipped with straight knife hole and is arranged on below the straight knife hole and is penetrated through with the straight knife hole;The material-dropping hole For with tapered hole, it is raised that anti-scrap bouncing is equipped with the tapered hole.
Further improved as the utility model, the aperture of the material-dropping hole from top to bottom gradually increases;It is described anti-jump The raised one end of bits is connected with the straight knife bottom hole portion, and the other end extends to the material-dropping hole lower end;The thickness of anti-scrap bouncing protrusion Gradually increase from top to bottom.
Further improved as the utility model, the anti-scrap bouncing is raised to have three, and angularly array exists in a ring On the taper internal surface of hole.
Further improved as the utility model, the taper of the tapered hole is 1 °.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art:
The punching anti-scrap bouncing lower die edge of a knife of the utility model, simple in structure, manufacture cost is low, and punch downlink is to material during work Piece is punched, and punch enters inside the edge of a knife, raised mutually with anti-scrap bouncing after generation waste material is driven into material-dropping hole by punch after punching Effect, is stuck in anti-scrap bouncing protrusion;When punch travels upward and out waste material, waste material can be not easy because being stuck in anti-scrap bouncing protrusion Stir and cause jump to be considered to be worth doing, considered to be worth doing so as to effectively prevent from jumping, it is ensured that the stability and security of production, while improve life The efficiency of production.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings:
Attached drawing 1 is the structure diagram of the punching anti-scrap bouncing lower die edge of a knife of the utility model;
In figure:1- lower die cutter hubs;2- straight knives hole;3- material-dropping holes;4- anti-scrap bouncings are raised.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in Figure 1, a kind of punching anti-scrap bouncing lower die edge of a knife of the utility model, including lower die cutter hub 1, lower die cutter hub 1 is equipped with straight knife hole 2 and the material-dropping hole 3 with taper, and the miner diameter end of material-dropping hole 3 is mutually connected with straight knife bottom hole portion, its small-and-middle diameter The aperture at end is equal to straight knife aperture;The bigger diameter end of material-dropping hole 3 down extends, until the cone through lower die cutter hub 1, wherein material-dropping hole Spend for 1 °.Anti-scrap bouncing protrusion 4 is equipped with material-dropping hole 3;Wherein, raised 4 one end of anti-scrap bouncing are connected with 2 bottom of straight knife hole, another End extends to material-dropping hole 3 and gives end;Anti-scrap bouncing protrusion has slope, its thickness from top to bottom gradually increases.
Anti-scrap bouncing protrusion 4 have three, in a ring angularly array on 3 inner surface of material-dropping hole.Punch downlink during work Tablet is punched, punch enters inside straight knife mouth 2, after generation waste material is driven into material-dropping hole by punch after punching, with anti-scrap bouncing Protrusion interaction, is stuck in anti-scrap bouncing protrusion, and when punch travels upward and out waste material, waste material can be because being stuck in anti-scrap bouncing protrusion It is interior, it is not easy to stir and causes jump to be considered to be worth doing, is considered to be worth doing so as to effectively prevent from jumping, it is ensured that the stability and security of production, at the same time Improve the efficiency of production.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it It is interior.
