Description
Technical field
The present invention relates to the manufacturing technology field of metallic article, more particularly, particularly a kind of punching press flange moulding process of basin frame.
Background technology
Within basin frame is mainly used in that container is fixed on to a space, basin frame adopts metal material, and metallic article is carried out to flange, is the common method among Sheet Metal Forming Technology.In flange, except there is plastic deformation, also can follow certain strain, cause like this flange metallic article afterwards to have rebound phenomenon, will cause thus flange shape afterwards not reach the requirement of design.
Summary of the invention
While the object of the present invention is to provide a kind of flange, prevent the punching press flange moulding process of the basin frame of resilience.
The punching press flange moulding process of basin frame of the present invention, comprises the following steps: S1. carries out the step of sawing sheet by shearing machine; S2. the step material after sawing sheet being positioned; S3. the step material of location being stretched; The step of S4. material after stretching being carried out to punching trimming; S5. the material after punching trimming is carried out the step of shock wave; S6. the step at preparation flange region punching press reinforcement to the material after shock wave; S7. the material after punching press reinforcement is carried out to flange, form basin frame product.
Preferably, among above-mentioned steps S6, described reinforcement is a plurality of salient points or concave point, or is ribs.
Preferably, among above-mentioned steps S6, described reinforcement is uniformly distributed in preparation flange region.
Preferably, among above-mentioned steps S6,10 to percent 20 of the thickness that the thickness of described reinforcement is material.
Compared with prior art, the advantage of invention is: the present invention is at preparation flange region punching press reinforcement, make the local deformation of material to reach the plastic deformation degree of material, therefore, material herein will be not can resilience, or springback capacity is very little, thereby avoided on the whole the resilience after parts flanged-edge.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult shown in Fig. 1, a kind of basin frame punching press flange moulding process provided by the invention, this technique comprises the following steps:
S1. by shearing machine, carry out the step of sawing sheet, according to sawing sheet, make the indication sizing of descending and on shearing machine, locate rear cutting;
S2. the step material after sawing sheet being positioned stamps out locating hole on the material of sawing sheet, and screw is fixed on to precalculated position through locating hole;
S3. the step material of location being stretched, is stretched as the stretching of not attenuation herein;
The step of S4. material after stretching being carried out to punching trimming;
Consult shown in Fig. 2, the trace 4 that is pressed in advance in the present invention comprises the second lower mold apparatus and at least one second upper mould device, wherein, the second upper mould device comprises the second upper padding plate 20, briquetting 21, the second slide block 22, the second punch 23, the second guide rail 24 and holding pad 29, briquetting 21 and holding pad 29 are all installed on the lower end of the second upper padding plate 20, the second slide block 22 is installed on the upper end of the second guide rail 24, the second guide rail 24 is installed on the second lower mold apparatus, the second punch 23 is installed on the second slide block 22, and the axis of the second punch 23 and horizontal line have an angle; The second lower mold apparatus comprises guide rail backing plate 25, the second lower bolster 26, the second die backing plate 27 and the second die 28, guide rail backing plate 25 and the second die backing plate 27 are all installed on the second lower bolster 26, and the second die 28 is installed on the second die backing plate 27 and is corresponding with the second punch 23.Wherein, the upper surface of the second guide rail 24 has an inclined plane, matches with the bottom surface of the second slide block 22 in this inclined plane, and the angle of inclination on this inclined plane equates with the angle between horizontal line with the axis of the second punch 23.
When punching press, the second upper padding plate 20 is descending, drives holding pad 29 to push down product, and the second slide block 22 is along the second guide rail 24 upper surface slide simultaneously, and 23 pairs of the second punch on the second slide block 22 carry out punching press to product, and clout is thoroughly departed from.
S6. the material after punching trimming is carried out the step of shock wave;
Consult shown in Fig. 3, shock wave mould 5 in the present invention, comprise the first upper mould device and the first lower mold apparatus, wherein, the first upper mould device includes the first upper padding plate 11, the first guide rail 12, spring dead plate 13 and the first slide block 14, the first guide rail 12 and spring dead plate 13 are all installed on the lower end of the first upper padding plate 11, the first slide block 14 is slidably installed on the first guide rail 12, the first slide block 14 is also connected with spring dead plate 13 elasticity, and on the first slide block 14, the first punch is also installed, the axis of the first punch and horizontal line have an angle; The first lower mold apparatus comprises oblique seat the 16, first die 17, the first die backing plate 18 and the first lower bolster 19, the first die backing plate 18 is installed on the first lower bolster 19, the first die 17 is installed on 18 and is corresponding with the first punch, and tiltedly seat 16 is installed on the first lower bolster 19 and is corresponding with the first slide block 14.Wherein, tiltedly the upper surface of seat 16 is an inclined plane, and match with the bottom surface of the first slide block 14 in this inclined plane, and the angle of inclination on this inclined plane equates with the angle between horizontal line with the axis of the first punch.
When punching press, the first upper padding plate 11 is descending, drives spring dead plate 13 to push down product, when first slide block 14 of the descending drive of the first guide rail 12 simultaneously on it slides on the first guide rail 12, product is carried out to shock wave.
S7. the step at preparation flange region punching press reinforcement to the material after shock wave, forms basin frame product.
Generally; among turn-up process; because part material is metal material; during flange except there is plastic deformation; also can follow certain strain; part after flange there will be rebound phenomenon conventionally owing to there is strain, will cause shape after parts flanged-edge not reach the requirement of design thus.
Among the present invention, before flange, in the preparation flange region punching press of part, form a plurality of salient points or concave point, or the ribs identical with flange direction.In the region that forms ribs, the local deformation of material will reach the plastic deformation degree of material, material herein will be not can resilience, or springback capacity is very little, thereby has avoided on the whole the resilience after parts flanged-edge.
When salient point or concave point or ribs are a plurality of, salient point or concave point are uniformly distributed, or the spacing between adjacent ribs is impartial.By practice, 10 to percent 20 of the thickness that the thickness that proves reinforcement is material, now prevents that the effect of parts flanged-edge is relatively good.
S7. the material after punching press reinforcement is carried out the step of flange, form basin frame product.
Although described by reference to the accompanying drawings working of an invention mode; but the patent owner can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of the claim of invention, all should be within the protection domain of invention.
