Description
Technical field
The utility model relates to metal plastic forming field of mechanical technique, specifically a kind of arc-shaped workpiece processing mold shaping for sheet metal component.
Background technology
As everyone knows, the flat part of various shape can be got off, if parts are curved by the direct stamping-out of punch press by punch die, then also need to use press-moulding die again compressing, its deficiency is: after having made punch die, also will make press-moulding die, during operation, complex procedures, die mould efficiency is low, and the equipment of use is many, during die mould, positioning precision is poor, waste time and energy, and profile unsightly, process loaded down with trivial details, Workpiece Machining Accuracy is low.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides that a kind of structure is simple, easy to process, machining accuracy is high, lightweight, equipment cost is low, the process-cycle is short, operating efficiency is high, the arc-shaped workpiece processing mold shaping for sheet metal component of good looking appearance.
The utility model solves the technical scheme that its technical problem adopts:
A kind of arc-shaped workpiece processing mold shaping for sheet metal component, comprise upper bolster, die shoe, lower punch and upper cavity die, it is characterized in that described lower punch lower surface is provided with the middle arcwall face to lower convexity, arc is formed after being beneficial to that arc-shaped workpiece is produced plastic deformation while blanking, described arcwall face front-end and back-end are respectively equipped with plane, are beneficial to reduce blanking pressure.
The width of the plane at arcwall face two ends described in the utility model is within 3mm, so that better reduce blanking pressure.
The arc radius R of the arcwall face of lower punch described in the utility model
convexfollowing formulae discovery is adopted to try to achieve:
According to formula
(1)
Wherein r is the arc radius of arc part;
T is sheet metal thickness;
K is the simplification coefficient of material, that is:
Formula
(2)
Wherein
for the yield strength of material; E is the elastic modelling quantity of material;
Formula (2) is brought in formula (1), can R be tried to achieve
convexarc radius.
The utility model, owing to adopting said structure, has the advantages such as structure is simple, easy to process, machining accuracy is high, lightweight, equipment cost is low, the process-cycle is short, operating efficiency is high, good looking appearance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of lower punch in the utility model.
Fig. 3 is the enlarged drawing of A in Fig. 2.
Reference numeral: upper bolster 1, die shoe 2, lower punch 3, upper cavity die 4.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of arc-shaped workpiece processing mold shaping for sheet metal component, comprise upper bolster 1, die shoe 2, lower punch 3 and upper cavity die 4, described lower punch 3 is fixed on upper bolster 2 lower end, described upper cavity die 4 is fixed on die shoe 2, described lower punch 3 is corresponding with upper cavity die 4, it is characterized in that described lower punch 3 lower surface is provided with the middle arcwall face to lower convexity, arc is formed after being beneficial to that arc-shaped workpiece is produced plastic deformation while blanking, described arcwall face front-end and back-end are respectively equipped with plane, are beneficial to reduce blanking pressure.
The width L of the plane at arcwall face two ends described in the utility model is within 3mm, so that better reduce blanking pressure.
The arc radius R of the arcwall face of lower punch 3 described in the utility model
convexfollowing formulae discovery is adopted to try to achieve:
According to formula
(1)
Wherein r is the arc radius of arc part;
T is sheet metal thickness;
K is the simplification coefficient of material, that is:
Formula
(2)
Wherein
for the yield strength of material; E is the elastic modelling quantity of material;
Formula (2) is brought in formula (1), can R be tried to achieve
convexarc radius.
The utility model is when punching press arc-shaped workpiece, to treat that the steel plate of stamping-out is placed on upper cavity die 4 end face, in upper cavity die 4 side, location-plate is set, by flat panel workpieces behind location-plate location, start control system, lower punch 3 is driven to move down, impact the flat panel workpieces on upper cavity die 4, flat panel workpieces passes through the stamping-out of lower punch 3 and upper cavity die 4, automatic formation arc-shaped workpiece, in blanking process, because the rear and front end at lower punch is respectively equipped with plane, substantially reduce the blanking pressure of workpiece, while sanction pressure blanking, the arc of the middle outwardly convex of lower punch 3 forms arc after making workpiece produce plastic deformation, reach effect easy to process.
The utility model, owing to adopting said structure, has the advantages such as structure is simple, easy to process, machining accuracy is high, lightweight, equipment cost is low, the process-cycle is short, operating efficiency is high, good looking appearance.
Claims (2)
