Abstract

The utility model relates to a kind of novel waste material knife structure, and it comprises the waste knife be located on edger base, and waste knife is three, is spaced setting, is in the arranged outside material blocking rod of the waste knife at two ends; The slide bar be obliquely installed of the waste knife that to be led by waste material is provided with in the inner side of the contiguous trimming product of waste knife.Waste material is slipped on waste knife along waste material slide bar, and during next part of trimming, waste material is divided by waste knife and is cut to three sections of discharges; In the process, waste knife is away from edge iron, and counterdie is for once sheared, and can not produce iron filings.

Description

A kind of novel waste material knife structure
Technical field
The utility model relates to a kind of punching press accessory, especially relates to a kind of novel waste material knife structure.
Background technology
Car body top cover outside plate is when automated production, automated production beat is very fast, trimming process step upper, counterdie deburring knife edge clearance is along with the lengthening of production time, because the high frequency time friction of edge of a knife when shearing makes edge of a knife heating and gap distortion, the edge of a knife produces heat fatigue phenomenon. and cause hardness to reduce, after there are wearing and tearing in the deburring edge of a knife, gap is uneven will produce deburring burr, the position arranged there being waste knife, burr is produced when plate is sheared by patrix waste knife, at the burr of junction, proceed in process in shearing, secondary shearing is carried out by patrix edge iron, as shown in Figure 1, when secondary shearing, easily the burr once shearing generation is wiped off, thus form a large amount of iron filings, as removed not in time, not only mould can be attached to, piece surface, and die surface and part generation are weighed wounded, also can be attached to below cutting edge and produce buildup, have a strong impact on the edge of a knife life-span.
Summary of the invention
The utility model main purpose is to provide a kind of novel waste material knife structure that around waste knife, iron filings produce when preventing the trimming of top cover outside plate.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of novel waste material knife structure, comprise the waste knife be located on edger base, it is characterized in that: waste knife is three, is spaced setting, be in the arranged outside material blocking rod of the waste knife at two ends; The slide bar be obliquely installed of the waste knife that to be led by waste material is provided with in the inner side of the contiguous trimming product of waste knife.Waste material is slipped on waste knife along waste material slide bar, and during next part of trimming, waste material is divided by waste knife and is cut to three sections of discharges; In the process, waste knife is away from edge iron, and counterdie is for once sheared, and can not produce iron filings.
As preferably, be provided with support plate bottom described slide bar, support plate is fixed on edger base.This structure, is easy to fixing, is convenient to the adjustment position of slide bar and the gradient of slide bar.
As preferably, the arc of slide bar bending in middle part indent.The effect of buffering can be played, reduce waste material to the impact of waste knife, thus play the effect of protection waste knife.
As preferably, the cross section of slide bar is circular.The cross section of slide bar is circular, reduces the contact area with waste material, reduces frictional force.
As preferably, material blocking rod is hook-shaped plate, is fixed on edger base bottom hook-shaped plate, and hook-shaped plate hook part is towards waste knife and extend to above waste knife end.This structure, structure is simple, be easy to make, and makes compact overall structure, and the hook part intensity of especially this structure is high, can bear larger impulsive force, and when waste material is cut by waste knife, material blocking rod is not yielding yet.
Therefore, the utility model have rational in infrastructure, be easy to the features such as making, the beneficial effect that when especially having a trimming of top cover outside plate, around waste knife, iron filings can not produce.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Accompanying drawing 2 is using state schematic diagrames of the present utility model.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of novel waste material knife structure of the utility model, as shown in accompanying drawing 1, accompanying drawing 2, it comprises the waste knife be located on edger base, and waste knife 1,3,6 is three, be spaced setting, be in the arranged outside material blocking rod 2,7 of the waste knife 1,6 at two ends; The slide bar 4 be obliquely installed of the waste knife 1,3,6 that to be led by waste material 5 is provided with in the inner side of the contiguous trimming product of waste knife 1,3,6.
Be provided with support plate bottom slide bar 4, support plate is fixed on edger base.When needing the gradient adjusting the position of slide bar and slide bar, regulate support plate.
The cross section of slide bar 4 is circular; The contact area with waste material can be reduced in circular cross section, reduces the frictional force of waste material and slide bar, prevents waste material two ends frictional force from not easily causing sliding speed to differ, prevent the situation causing waste material slide-down not in place.
Slide bar 4 bends the arc in middle part indent.The arc of indent can play the effect of buffering, reduces waste material to the impact of waste knife, thus plays the effect of protection waste knife
Material blocking rod 2,7 is hook-shaped plate, is fixed on edger base bottom hook-shaped plate, and hook-shaped plate hook part is towards waste knife 1,6 and extend to above waste knife 1,6 end.Hook part intensity is high, can bear larger impulsive force, and when waste material is cut by waste knife, material blocking rod is not yielding yet.
After part trimming, waste material 5 is along waste material slide bar 4 landing, and waste material blocks by material blocking rod 2 and 7, and when trimming next part, waste material is cut to three sections by waste knife 1,3 and 6 points and discharges outside mould.In the process, waste knife is away from edge iron, and counterdie is for once sheared, and can not produce iron filings.
Compared with traditional trimming waste knife structure, independent waste knife structure of the present utility model is away from counterdie edge iron, non-intersect with edge iron, although jagged during deburring, can not secondary shearing, therefore can not iron filings be produced, and improve exterior panel and once to roll off the production line qualification rate.
