Please with reference to Fig. 1; Be a preferred embodiment of the present invention; This mobile phone shielding sheet metal forming technological equipment; In order to the control system (not shown) that a sheet metal 4 is molded the mobile phone shielding plate 41 of a plurality of predetermined convex-concave shapes, comprise first pressing equipment 1 that sets gradually, first forging equipment 2, second pressing equipment 3 and coordinate aforementioned each several part action.Like this, because employing is above-mentioned through the control of control system and pressing equipment and forging equipment that organically combine, make it form a flexible production line; Carry out the work of multiple devices coordination linkage; This continual serialization production has not only guaranteed the stable of product quality, and is fit to produce in enormous quantities; Can reach 1500～2700/hour, improve production efficiency greatly.
Below present embodiment is done further to introduce in detail.
In the present embodiment, said sheet metal 4 is banded aluminium, and thickness is no more than 3 millimeters.Before carrying out the punching press first time, said sheet metal 4 is a rolled and is positioned on the uncoiler 5.So in order to eliminate the deflection of material, reach the flatness of technological requirement, be provided with the leveling apparatus 6 of said sheet metal 4 being smoothed processing in the said first pressing equipment pan feeding, one side.Levelling machine is identical in said leveling apparatus 6 and the prior art, includes the last straightener roll wheels 61 and following straightener roll wheels 62 that are oppositely arranged.
With reference to Fig. 1; Said first pressing equipment 1 is provided with a plurality of cold-punching molding moulds 11, and these a plurality of cold-punching molding moulds 11 surfaces are provided with and the identical shaping mould portion of said mobile phone shielding plate 41 profiles, after 11 pairs of sheet metals of cold-punching molding mould 4 carry out local punching press; Can on sheet metal 4, form a plurality of stock (not shown)s; Said stock satisfies postorder when forging and pressing size needs, and stock do not break away from said sheet metal 4, can under the control system drive, travel forward with sheet metal 4.
Said first forging equipment 2 is provided with cold-forge forming mould 21, through 21 forging and pressing of cold-forge forming mould, on each stock on the sheet metal 4, forms single, double convex-concave offset, reaches the convex-concave shape that mobile phone shielding plate 41 requires, as shown in Figure 2.During forging and pressing, forging force is controlled at 600T～1000T, and forge speed is controlled to be 25～40 times/minute.Adopt this control parameter, to banded aluminium in the present embodiment, after forging and pressing, final mobile phone shielding plate 41 intensity that obtain and precision are high, and surface quality is good.
In the present embodiment; Before forging and pressing, increased by one second forging equipment 7 and carried out the blocking pressure through first forging equipment 2; Through this blocking operation, not only can reduce the wearing and tearing in cold mould chamber in postorder first forging equipment 2, and can obtain forging quality preferably.Certainly,, also can omit second forging equipment 7 here, get final product through a cold-forge forming through first forging equipment 2 according to the difference of final mobile phone shielding plate 41.
Said second pressing equipment 3 is provided with a plurality of diels 31; Said diel 31 comprises perforating die, edger, bending die and blanking die; On this second pressing equipment 3 through the punching press of above-mentioned diel; Completion is to forging and pressing punching, side cut, bending and the blanking of back sheet metal 4, the final mobile phone shielding plate 41 that forms as shown in Figure 2.
In the present embodiment, the working face of said uncoiler 5, leveling apparatus 6, first pressing equipment 1, second forging equipment 7, first forging equipment 2 and second pressing equipment 3 is in sustained height.In order to make the motion of said sheet metal 4 between each device more smooth and easy, controlled, pan feeding one side in first pressing equipment 1, second forging equipment 7, first forging equipment 2 and second pressing equipment 3 in the present embodiment all is provided with the pay-off 8 that can impose pulling force to said sheet metal 4.Said pay-off 8 is with each device and is wholely set.
Before each Sheet Metal Forming Technology equipment started in the present embodiment, the sheet metal 4 that will be web-like was positioned on the uncoiler 5.The start-up control system, the sheet metal 4 of web-like has good flatness through the relative roll extrusion of the last straightener roll wheels 61 and the following straightener roll wheels 62 of leveling apparatus 6, gets into first pressing equipment 1 then and carries out punching press formation stock.
Said sheet metal 4 carries out blocking through second forging equipment 7 again presses, carries out the secondary cold forging through pay-off 8 entering first forging equipment 2 then, makes to form single, double convex-concave offset on the stock, reaches the convex-concave shape of final mobile phone shielding plate 41.
For the second time in the punch steps; Sheet metal 4 after will forging and pressing through pay-off 8 is sent in second pressing equipment 3; Through each stamping die punching press of second pressing equipment 3, accomplish punching, side cut, bending and blanking to press forging, finally form a plurality of mobile phone shielding plates 41 as shown in Figure 2.
To sum up, in the mobile phone shielding panel forming method, adopt the banded preferably aluminium of precision to carry out continuous punching press forging and pressing among the present invention; Thereby form a flexible production line, mobile phone shielding plate 41 does not break away from banded aluminium and blanking completion in final stamping procedure in process of production, this continual serialization production; Guaranteed the stable of product quality; Be fit to produce in enormous quantities, can reach 1500～2700/hour, improved production efficiency greatly.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
