Description
[technical field]
The present invention relates to curve generating processing mold technical field, specifically a kind of Sheet Metal Surface shaping stamping mold
Tool.
[background technology]
Currently, for processing curve sheet material workpiece, traditional method is all to use straight line punch-pin and the recessed punching press touched of straight line
Mold is formed, and post-order process secondary process is recycled to realize the forming of target workpiece.The mode of production efficiency is low, bent plate matter
Amount can not ensure, relatively mostly use multiple spot forming method at present, its main feature is that up and down adjustment is multiple to press certain regularly arranged punch,
The curve form for constructing board product completes the molding of board product by up and down action.However, this method is only applicable to
Small lot can not be produced in enormous quantities, and production cost is excessively high, and processing is complex, cannot be satisfied automobile, aircraft, ship
Deng the Strategic Demand for manufacturing industry sustainable development.
[invention content]
A kind of Sheet Metal Surface shaping and punching mold is provided present invention aim to solve above-mentioned deficiency, Neng Goujian
The processing complexity for changing curved surface plank realizes that the flexural deformation of plank, cooperation are more by controlling the longitudinal movement amplitude of punch-pin
Passage progressive molding method, is finally completed the processing of high-precision workpiece, greatly reduces production cost.
A kind of Sheet Metal Surface shaping and punching mold, including punch-pin 1 and cavity plate 2, the punch-pin 1 are designed to achieve the above object
Positioned at the top of cavity plate 2, the stamping surface of the punch-pin 1 and cavity plate 2 is cambered flexure plane, the punch-pin 1 and cavity plate 2
Stamping surface is intermeshed, and groove 3 is horizontally arranged on the cavity plate 2, and the thickness of the punch-pin 1 is less than the groove width of groove 3, institute
It is fixed to state cavity plate 2, the punch-pin 1 moves longitudinally.
The punch-pin 1 is of same size with cavity plate 2.
The process for stamping of the Sheet Metal Surface shaping and punching mold, includes the following steps：Cavity plate 2 is fixed on operating platform
On, sheet material workpiece is placed between punch-pin 1 and cavity plate 2, punch-pin 1 moves longitudinally under the drive of hydraulic lift, to work
Part carry out punch process, by adjust 1 amount of movement of punch-pin control punch-pin 1 and cavity plate 2 degree of engagement, while dependence punch-pin 1 with it is recessed
The radian of mould 2 controls the bending curvature of sheet material workpiece, and target three-dimension curved surface work is bent into through multi-pass progressive molding method after
Part.
The present invention compared with the existing technology, has the following advantages that：
(1) stamping surface of punch-pin and cavity plate is at certain radian, and can be intermeshed, to which workpiece bows shape nature；
(2) punch-pin has identical width with cavity plate, and the thickness of punch-pin is less than the groove width of cavity plate, so as to avoid plank quilt
Cavity plate goes out impression with punch-pin, ensure that target workpiece is smooth；
(3) the processing complexity that can simplify curved surface plank realizes plank by controlling the longitudinal movement amplitude of punch-pin
Flexural deformation, coordinate multi-pass progressive molding method, be finally completed the processing of high-precision workpiece；
(4) degree of engagement of punch-die is controlled by adjusting punch-pin amount of movement, while by the radian of punch-die, realizing control
The bending curvature of plank；
(5) batch production of the products such as large ship molded line outside plate, aircraft outside plate can be suitable for, processing can be made simple
Change, greatly reduces production cost.

[specific implementation mode]
The present invention is made below in conjunction with the accompanying drawings further explained below：
As shown in attached drawing 1 to attached drawing 3, the present invention provides a kind of Sheet Metal Surface shaping and punching mold, including punch-pin 1 and recessed
Mould 2, punch-pin 1 are located at the top of cavity plate 2, and the stamping surface of punch-pin 1 and cavity plate 2 is cambered flexure plane, punch-pin 1 and cavity plate 2
Stamping surface intermeshing, be horizontally arranged with groove 3 on cavity plate 2, the thickness of punch-pin 1 is less than the groove width of groove 3, punch-pin 1 with
Cavity plate 2 it is of same size, cavity plate 2 is fixed, and punch-pin 1 moves longitudinally.
The process for stamping of the Sheet Metal Surface shaping and punching mold, includes the following steps：Cavity plate 2 is fixed on operating platform
On, sheet material workpiece is placed between punch-pin 1 and cavity plate 2, punch-pin 1 moves longitudinally under the drive of hydraulic lift, to work
Part carry out punch process, by adjust 1 amount of movement of punch-pin control punch-pin 1 and cavity plate 2 degree of engagement, while dependence punch-pin 1 with it is recessed
The radian of mould 2 controls the bending curvature of sheet material workpiece, and target three-dimension curved surface work is bent into through multi-pass progressive molding method after
Part.
