Abstract
The invention relates to the technical field of curved surface forming dies, in particular to a sheet material curved surface forming stamping die which comprises a convex die (1) and a concave die (2), wherein the convex die (1) is positioned above the concave die (2); the stamping surfaces of the convex die (1) and the concave die (2) are curved surfaces with radians and are engaged with each other; a groove (3) is formed in the concave die (2) in the transverse direction; the thickness of the convex die (1) is smaller than the width of the groove (3); the concave die (2) is fixed; and the convex die (1) moves in the longitudinal direction and is as wide as the concave die (2). Compared with the prior art, the sheet material curved surface forming stamping die is novel and simple in structure and reasonable in design, can simplify the machining complexity of a curved surface sheet material, realizes curved deformation of the sheet material by controlling the longitudinal movement range, is matched with the multi-pass incremental forming method to finally finish high-precision workpiece machining, and greatly reduces the production cost.
Description
[technical field]
The present invention relates to curve generating processing mold technical field, specifically a kind of Sheet Metal Surface shaping and punching mould.
[background technology]
At present, for processing curve sheet material workpiece, traditional method is all adopt straight line punch and the recessed diel of touching of straight line to form, the shaping of recycling post-order process secondary process realize target workpiece.This mode of production efficiency is low, and bent plate quality cannot ensure, current more employing multiple spot forming method, is characterized in that up-down adjustment is multiple by necessarily regularly arranged drift, constructs the curve form of board product, complete the shaping of board product by knee-action.But this method is only applicable to small lot, cannot produce in enormous quantities, and production cost is too high, processing is comparatively complicated, cannot meet the Strategic Demand that industry sustainable development manufactured by automobile, aircraft, boats and ships etc.
[summary of the invention]
Object of the present invention is exactly will solve above-mentioned deficiency and provide a kind of Sheet Metal Surface shaping and punching mould, the processed complex degree of curved surface sheet material can be simplified, by controlling the lengthwise movement amplitude of punch, realize the flexural deformation of sheet material, coordinate multi-pass progressive molding method, finally complete the processing of high-precision workpiece, greatly reduce production cost.
Design a kind of Sheet Metal Surface shaping and punching mould for achieving the above object, comprise punch 1 and die 2, described punch 1 is positioned at the top of die 2, described punch 1 and the stamping surface of die 2 are the flexure plane of radian, described punch 1 engages each other with the stamping surface of die 2, and described die 2 is horizontally arranged with groove 3, and the thickness of described punch 1 is less than the groove width of groove 3, described die 2 maintains static, and described punch 1 moves longitudinally.
Described punch 1 is identical with the width of die 2.
The process for stamping of this Sheet Metal Surface shaping and punching mould, comprise the following steps: die 2 is fixed on the operational platform, sheet material workpiece is placed between punch 1 and die 2, punch 1 moves longitudinally under the drive of hydraulic lift, punch process is carried out to workpiece, by the degree of engaging of adjustment punch 1 amount of movement control punch 1 with die 2, rely on the radian of punch 1 and die 2 simultaneously, control the bending curvature of sheet material workpiece, with after be bent into target three-dimension curved surface workpiece through multi-pass progressive molding method.
Compared with the existing technology, tool has the following advantages in the present invention:
(1) punch becomes certain radian with the stamping surface of die, and can engage each other, thus workpiece bows shaping nature;
(2) punch and die have identical width, and the thickness of punch is less than the groove width of die, thus sheet material can be avoided to be gone out impression by die and punch, ensure that target workpiece is smooth;
(3) the processed complex degree of curved surface sheet material can being simplified, by controlling the lengthwise movement amplitude of punch, realizing the flexural deformation of sheet material, coordinate multi-pass progressive molding method, finally complete the processing of high-precision workpiece;
(4) the engagement degree by regulating punch amount of movement to control punch-die, relies on the radian of punch-die simultaneously, realizes the bending curvature controlling sheet material;
(5) batch production of the products such as large ship molded line outside plate, aircraft outside plate can be applicable to, processing summary can be made, greatly reduce production cost.

[detailed description of the invention]
Below in conjunction with accompanying drawing, following further illustrating is done to the present invention:
As shown in accompanying drawing 1 to accompanying drawing 3, the invention provides a kind of Sheet Metal Surface shaping and punching mould, comprise punch 1 and die 2, punch 1 is positioned at the top of die 2, and punch 1 is the flexure plane of radian with the stamping surface of die 2, punch 1 engages each other with the stamping surface of die 2, die 2 is horizontally arranged with groove 3, the thickness of punch 1 is less than the groove width of groove 3, and punch 1 is identical with the width of die 2, die 2 maintains static, and punch 1 moves longitudinally.
The process for stamping of this Sheet Metal Surface shaping and punching mould, comprise the following steps: die 2 is fixed on the operational platform, sheet material workpiece is placed between punch 1 and die 2, punch 1 moves longitudinally under the drive of hydraulic lift, punch process is carried out to workpiece, by the degree of engaging of adjustment punch 1 amount of movement control punch 1 with die 2, rely on the radian of punch 1 and die 2 simultaneously, control the bending curvature of sheet material workpiece, with after be bent into target three-dimension curved surface workpiece through multi-pass progressive molding method.
In the present invention, punch becomes certain radian with the stamping surface of die, and can engage each other; Punch and die have identical width, and the thickness of punch is less than the groove width of die.This Design of Dies can simplify the processed complex degree of curved surface sheet material, by controlling the lengthwise movement amplitude of punch, realizes the flexural deformation of sheet material, coordinates multi-pass progressive molding method, finally completes the processing of high-precision workpiece.
The present invention, by the restriction of above-mentioned embodiment, change, the modification done, substitutes, combines, simplifies under other any does not deviate from Spirit Essence of the present invention and principle, all should be equivalent substitute mode, is included within protection scope of the present invention.
