Description
Technical field
The utility model relates to hardware stamping Bending Mould structural design field, the non-linear accurate Bending Mould of particularly a kind of metal material.
Background technology
Along with the development and the progress of society, existing conventional molds technology is backward, and the wrap direction of single stage die has satisfied not requirement of products, occurs that production efficiency is low, cost is high, the unsettled present situation of size.To some non-linear bending and formings, broken backed size instability, distortion just occur seriously especially, fraction defective is high, has increased processing cost, and the maintenance frequency of mould increases, wastes resource.And improved multiple wrap direction, as the thruster wrap direction, the substep wrap direction, add beading multistation wrap direction, owing to various reasons, all do not reach high-quality requirement.
Summary of the invention
The utility model proposes for the shortcoming that overcomes above prior art existence, and the technical problem that it solved provides a kind of simple to operate, and bending is partly twisted few, and size is steady, the non-linear accurate Bending Mould of the metal material that fraction defective is low.
For this reason; The utility model provides a kind of metal material non-linear accurate Bending Mould, comprises punch press platform, upper die component, following membrane module and Bending punch, wherein descends membrane module to be installed on the punch press platform; Following membrane module sets gradually by bottom seat pad, die shoe, lower bolster and lower bolster from bottom to top; Upper die component comprises punch press module, upper bolster, upper padding plate, cope match-plate pattern and holding pad, and described punch press module is positioned at the upper bolster top, and lower bolster is provided with two dies; Two die top correspondences are equipped with Bending punch, and Bending punch is installed on the upper bolster and passes holding pad.
Described die is provided with the precompressed muscle, and the setting of precompressed muscle can make the thick attenuation of bending part material, reduces the shearing strength in step down.
There is a rectangular breach lower end of described Bending punch, and rectangular breach is 1/2nd of a drift integral body, makes drift form one high and one low two cross sections.
As the further improvement of the utility model, Bending punch is divided into first Bending punch and second Bending punch, and wherein the length of first Bending punch is shorter than second Bending punch.
The beneficial effect of the utility model is:
The utility model simplicity of design, rational in infrastructure, Bending punch is notched height cross section structure design; Bending pressure is disperseed, resisted torsion, the screen resilience of bending, guarantee non-linear accurate bending series products dimensional stability; Reduce cost, strengthened the functional of product.The utility model has solved the distortion problem of the accurate part of non-linear bending, makes the bending dimensionally stable, reaches volume production.
Description of drawings
Fig. 1 is the structural representation of the non-linear accurate Bending Mould of the utility model metal material.
Fig. 2 is Figure 1A portion enlarged drawing.
Fig. 3 is the sketch map of the drift of the said Bending Mould of the utility model.
Among the figure: 1-punch press platform, 2-bottom seat pad, 3-die shoe, 4-lower bolster, 5-lower bolster, 6-holding pad, 7-cope match-plate pattern, 8-upper bolster, 9-upper padding plate, 10-Bending punch, 101 first Bending punches, 102 second Bending punches, 11-punch press module, 12-die, 13-precompressed muscle, 14-metal material.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
Like Fig. 1, shown in Figure 2; The non-linear accurate Bending Mould of a kind of metal material; Comprise punch press platform 1, upper die component, membrane module and Bending punch 10 down, wherein descend membrane module to be installed on the punch press platform 1, following membrane module is disposed with bottom seat pad 2, die shoe 3, lower bolster 4 and lower bolster 5 from bottom to top; Upper die component comprises punch press module 11, upper bolster 8, upper padding plate 9, cope match-plate pattern 7 and holding pad 6; Lower bolster 5 is provided with 12, two dies of two dies, 12 top correspondences Bending punch 10 is installed, and Bending punch 10 is installed on the upper bolster 8 and passes holding pad 6.
As shown in Figure 3, there is a rectangular breach lower end of Bending punch 10, and rectangular breach is 1/2nd of Bending punch 10 integral body, makes Bending punch 10 form one high and one low two cross sections.Die 12 is provided with precompressed muscle 13, and the setting of precompressed muscle 13 can make the thick attenuation of bending part material, reduces the shearing strength in step down.
As the further improvement of the utility model, as shown in Figure 2, Bending punch 10 is divided into first Bending punch 101 and second Bending punch 102, and wherein the length of first Bending punch 101 is shorter than second Bending punch 102.
The described specific embodiment of the utility model is following:
1, on die 12, increases precompressed muscle 13; The metal material of treating bending 14 is placed on the die 11; Metal material 14 comprises aluminium flake, copper sheet, iron plate and other sheet metals; The setting of precompressed muscle 13 can make the thick attenuation of bending part material, reduces the shearing strength in step down, helps the formation of bending shape.
2,45 degree pre-fold: Bending punch 10 is descending, and the high cross section of first Bending punch 101 contacts with the bending material earlier, forms 45 degree and pre-folds, and to reduce the bending power of final step, makes bending become more stable.
3, the smart folding of 90 degree: the material 14 that 45 degree that will form pre-fold moves on the corresponding die 11 of second Bending punch 102, second Bending punch 102 descending and by its low cross section to metal material 14 overvoltages, form 90 and spend bendings, make the bending angle more precise and stable.
The utility model utilizes the characteristic of metal material; The competing phase of power and power is negative in the bending process offsets, and through material is carried out overvoltage, makes the material plastic deformation; Thereby reach the bending dimensionally stable; Guarantee non-linear accurate bending series products dimensional stability, reduced cost, strengthened the functional of product.
