Abstract
This utility model relates to the accurate cutting edge structure of a kind of aluminum alloy mould, and the lower mold cutting edge lower end of lower mold side surface is intilted lower mold inclined-plane, and the upper surface in lower mold is provided with eccentric swage, and eccentric swage side surface indentation is in the side surface of lower mold cutting edge；Being provided with upper mold outside lower mold, the lower end of upper mold is upper mold cutting edge, and the upper end of upper mold cutting edge is provided with intilted upper mold inclined-plane, and upper mold cutting edge coordinates with lower mold cutting edge radius.This cutting edge structure avoids the viscous glutinous die point of aluminum bits, thus improves the mold use life-span, alleviates maintenance cost, and entirety reduces production cost.
Description
Technical field
This utility model relates to the accurate cutting edge structure of a kind of aluminum alloy mould, belongs to mould applications.
Background technology
Along with the highlighting of various problems of environmental pollution and fuel economy, automotive light weight technology technology starts extensively to apply.
Presently the most effective technology is exactly alleviating of complete vehicle weight, and the application of all-aluminium body technology can make complete vehicle weight alleviate 30%
To 40%.Current each big Automobile Enterprises all replaces original steel plate punched at trial aluminium alloy stamping parts in different vehicles
Part.But also bring many technical problems, when aluminium alloy stamping parts deburring produces, due to upper mold cutting edge and lower mold cutting edge first
Making it produce partial loop variation when shearing aluminum material, upper mold cutting edge continues traveling downwardly formation secondary shearing and produces aluminum bits the most for the first time；
And after down cut terminates, upper mold cutting edge backhaul, produce and aluminum material is rewinded fricting shearing i.e. second time generation aluminum bits.Due to aluminum
Bits are easily sticky on die point, and are difficult to remove, and damage cutting edge, cause tipping etc., to production efficiency when accumulating too much
The aluminum bits that no more than Trimming Die produce maximum with quality restriction, the viscous glutinous cutting edge of aluminum bits not only affects die life, has an effect on
Production efficiency, needs periodic cleaning, otherwise will affect part quality.And the time-based maintenance used at present, the method for safeguarding mould
Considerably increase the production cost of product.
Summary of the invention
The technical problems to be solved in the utility model is to provide the accurate cutting edge structure of a kind of aluminum alloy mould, and this cutting edge is tied
Structure avoids the viscous glutinous die point of aluminum bits, thus improves the mold use life-span, alleviates maintenance cost, and entirety reduces production
Cost.
For solving problem above, concrete technical scheme of the present utility model is as follows: the accurate cutting edge of a kind of aluminum alloy mould
Structure, the lower mold cutting edge lower end of lower mold side surface is intilted lower mold inclined-plane, and the upper surface in lower mold is provided with eccentric swage, pressure
Glassware side surface indentation is in the side surface of lower mold cutting edge；Being provided with upper mold outside lower mold, the lower end of upper mold is upper mold cutting edge, upper mold
The upper end of cutting edge is provided with intilted upper mold inclined-plane, and upper mold cutting edge coordinates with lower mold cutting edge radius.
The described distance between upper mold cutting edge side surface and eccentric swage side surface be C be 0.2mm ~ 0.5mm.
The height of described lower mold cutting edge be A be 2 ~ 3t, wherein t for material thickness.
The height of described upper mold cutting edge be B be 1 ~ 1.5t, wherein t for material thickness.
The side end face of upper mold cutting edge and lower mold cutting edge is set to inclined-plane by the accurate cutting edge structure of this aluminum alloy mould, therefore subtracts
Contact area in little shear history, it is to avoid the production of aluminum bits.
Adjust upper mold cutting edge and lower mold cutting edge structure size, fit clearance and the rational fit dimension of eccentric swage etc., mutually
Effect realizes the suppression generating aluminum bits, simple in construction, promotes part quality, reduces production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the accurate cutting edge structure of aluminum alloy mould.
Detailed description of the invention
As it is shown in figure 1, the accurate cutting edge structure of a kind of aluminum alloy mould, the aluminum plate material that thickness is t is punched out, under
Lower mold cutting edge 4 lower end of mould 3 side surface is intilted lower mold inclined-plane 5, the height of lower mold cutting edge 4 be A be sheet thickness t's
2 ~ 3 times；Upper surface in lower mold 3 is provided with eccentric swage 2, and eccentric swage 2 side surface indentation is in the side surface of lower mold cutting edge 4, lower mold sword
The angle of mouthful 4 side surfaces and vertical plane be β be 8 ~ 12 °；Being provided with upper mold 1 outside lower mold 3, the lower end of upper mold 1 is upper mold cutting edge
6, the height of upper mold cutting edge 6 be B be 1 ~ 1.5 times of sheet thickness t；It is oblique that the upper end of upper mold cutting edge 6 is provided with intilted upper mold
Face 7, the side surface on upper mold inclined-plane 7 and the angle of vertical plane be α be 1 ~ 1.5 °, and upper mold cutting edge 6 is joined with lower mold cutting edge 4 gap
Close, and the distance between upper mold cutting edge 6 side surface and eccentric swage 2 side surface be C be 0.2mm ~ 0.5mm.
In sum, by the cooperation of the technical parameter between above-mentioned lower mold cutting edge 4, upper mold cutting edge 6 and eccentric swage 2, can
With the generation avoiding aluminum to consider to be worth doing, the accurate cutting edge structure of the aluminum alloy mould of the application can extensively be applied and be adapted to aluminium alloy punching press
The trimming process step of product, can be widely applied to mould manufacturing field and punching production industry.
