Abstract
The invention discloses an arc-shaped workpiece processing mold for sheet metal part forming. The arc-shaped workpiece processing mold comprises an upper mold seat, a lower mold seat, a lower male mold and an upper female mold and is characterized in that the lower end surface of the lower male mold is provided with an arc-shaped surface with the downwards projected middle, so that an arc-shaped workpiece can form an arc shape after the plastic deformation during blanking, the front end and the back end of the arc-shaped surface are respectively provided with planes, and the blanking force can be favorably reduced. By adopting the structure, the arc-shaped workpiece processing mold has the advantages that the structure is simple, the processing is convenient, the processing precision is high, the weight is light, the equipment cost is low, the processing period is short, the work efficiency is high, the appearance is attractive, and the like.
Description
Technical field
The present invention 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 object of the invention is to solve above-mentioned the deficiencies in the prior art, provide 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 technical solution adopted for the present invention to solve the technical problems is:
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 of the present invention is within 3mm, so that better reduce blanking pressure.
The arc radius R of the arcwall face of lower punch of the present invention
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 present invention, 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 invention.
Fig. 2 is the structural representation of lower punch in the present invention.
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, arcwall face 5, plane 6.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further described:
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 5 to lower convexity, arc is formed after being beneficial to that arc-shaped workpiece is produced plastic deformation while blanking, described arcwall face 5 front-end and back-end are respectively equipped with plane 6, are beneficial to reduce blanking pressure.
The width L of the plane 6 at arcwall face 5 two ends of the present invention is within 3mm, so that better reduce blanking pressure.
The arc radius R of the arcwall face 5 of lower punch 3 of the present invention
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 present invention 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 present invention, 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.
