Description
Technical field
The present invention relates to the three-dimensional sheet material parts machining forming method of three-dimensional sheet material parts machining technology, the particularly porose bit architecture of a kind of bending part band.
Background technology
Existing three-dimensional sheet material parts machining forming method has two kinds of selections: the one, first use the bender shape molding that stretched, and then with milling machine, the position, hole required is processed, its weak point: machining hole position location difficulty, machining hole bit position precision is not high, complex process, cost is high, and efficiency is low.The 2nd, first the three-dimensional sheet material parts of processing object are launched into to two-dimension plane structure, press the outline of two-dimension plane structure in two-dimentional sheet material loading and unloading moulding simultaneously, carry out again the processing of position, hole on the flat sheet of blanking moulding with milling machine, finally use bender to carry out drawing and forming, its weak point: for the three-dimensional sheet material parts of the porose bit architecture of bending part band, in bending and molding 3 D workpiece process, because the flat sheet bending stretches, the position, hole of bending part is in the material extending scope, can cause the porose position of bending part band that deformation occurs thereupon, do not reach required precision.Therefore, the three-dimensional sheet material parts for the porose bit architecture of bending part band generally adopt the first processing method.
Summary of the invention
The objective of the invention is to design a kind of processing location easily, machining hole position positional precision is high, and the three-dimensional sheet material parts machining forming method of position, the bending part hole porose bit architecture of bending part band that is difficult for deforming.
In order to achieve the above object, the present invention adopts following technical solution: the three-dimensional sheet material parts machining forming method of the porose bit architecture of a kind of bending part band is characterized in that its processing molding method carries out according to the following steps:
(1) first the three-dimensional sheet material parts of processing object are launched into to the flat deployable structure design drawing one time by structure;
(2) for the three-dimensional sheet material component structural of the porose bit architecture of bending part band, on the basis of a described flat deployable structure design drawing, establish " C " font technique mouth in described hole bit architecture one side near bending design sideline, become secondary flat deployable structure design drawing;
(3) adopt plane laser cutting machine according to described secondary flat deployable structure design drawing, carry out excision forming on flat sheet, form two-dimentional half-finished parts;
(4) use bender to carry out drawing and forming to described expansion half-finished parts, form three-dimensional sheet material parts.
The flanging extruding occurs when the bending in the present invention for the three-dimensional sheet material parts that prevent adjacent two folded edges, technique scheme is further arranged: for the three-dimensional sheet material parts that adjacent two folded edges are arranged, on the basis of a described planar structure design drawing, in the crosspoint of adjacent two flanging design lines, be provided with anti-extrusion technique mouth.
The present invention, on limited locus, cuts out anti-drawing process mouth effectively, and technique scheme is further arranged: the groove width of described " C " font technique mouth is between 3mm-5mm.
The present invention compared with prior art, the beneficial effect had is: the three-dimensional sheet material parts of the porose bit architecture of bending part band only need be through the one-time positioning design, a laser cutting, and one time bending and molding just can complete production in batches, greatly reduce the machinery production cost, improve Product Precision.Laser cutting technique is supported the 0.3mm joint-cutting, makes the exploitation of technique mouth complete smoothly.

The specific embodiment:
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The present embodiment is usingd two practical application processing objects as case, and the three-dimensional sheet material parts machining forming step to bending part with the hole bit architecture describes, and its processing molding method carries out according to the following steps:
(1) first the three-dimensional sheet material parts of processing object are launched into to a planar structure design drawing (seeing Fig. 2 and Fig. 6) by structure (seeing Fig. 1 and Fig. 5);
(2) for the three-dimensional sheet material component structural of the porose bit architecture 3 of bending part band, on the basis of a described planar structure design drawing, establish " C " font technique mouth 2 in described hole bit architecture 3 one sides near bending design sideline 1, become secondary planar structure design drawing (seeing Fig. 3 and Fig. 7).The groove width of described " C " font technique mouth 2 is between 3mm-5mm, and groove width is little, and after the moulding of three-dimensional sheet material parts, " C " font technique mouth does not affect three-dimensional sheet material parts profile.
In addition, the three-dimensional sheet material parts of adjacent two folded edges are arranged for similar second processing object, on the basis of a described planar structure design drawing, in the crosspoint of adjacent two flanging design lines 4, be provided with anti-extrusion technique mouth 5 (seeing Fig. 7).
(3) adopt plane laser cutting machine according to described secondary planar structure design drawing, carry out the one-time positioning design on flat sheet, a laser cutting
Outline, position, various hole, " C " font technique mouth and the one-shot forming of anti-extrusion technique mouth, form two-dimentional half-finished parts.
(4) use bender to carry out bending, drawing and forming to described two-dimentional half-finished parts, form three-dimensional sheet material parts (seeing Fig. 4 and Fig. 8).
Because laser cutting technique is supported the 0.3mm joint-cutting, therefore the present embodiment can be on limited locus, cut out anti-drawing process mouth effectively, make the plate body of the porose bit architecture of bending part band be cut off, guaranteed that two-dimentional half-finished parts is in bending, drawing and forming process, the plate body at bit architecture place, hole is not stretched, and the hole bit architecture is not subject to bending, stretch effects, be difficult for deformation occurs, improved position, hole and the dimensional accuracy of product.
In addition, the present embodiment is provided with anti-extrusion technique mouth 5 in the crosspoint that adjacent two folded edges are arranged, and also is convenient to the bending and molding of two-dimentional half-finished parts.
