Abstract
Description
- Many devices include components that are manufactured in a variety of manners. For example, certain devices or components are formed of plastic using injection molding, while others may be formed of a metal that may be forged, machined, or otherwise shaped. The method of forming the component may be selected based on such factors as strength or surface shape desired.
- For a more complete understanding of various examples, reference is now made to the following description taken in connection with the accompanying drawings in which:
-
FIG. 1 illustrates an example system for stamping metal components; -
FIG. 2 illustrates another example system for stamping metal components; -
FIGS. 3-5 illustrate various phases of the stamping of a metal component using the example system ofFIG. 2 ; -
FIG. 6 illustrates another example system for stamping metal components; -
FIG. 7 illustrates another example system for stamping metal components; and -
FIG. 8 is a flow chart illustrating an example method for stamping of metal components. - Various mechanisms may be used for forming different components or devices. For metal components, certain features can be achieved through stamping of a metal component. Stamping can often result in defects on the surface of a component. The defects can include significant non-uniformity of the stamped surface. For certain components and materials, the non-uniformity of the surface can, in turn, result in non-uniformity in color or appearance of the surface. Further, for certain components, the non-uniformity may be significantly noticeable to the touch by a user.
- In various examples described herein, metal components may be stamped to form a desired shape or feature. For example, the body of a laptop computer may have a cover with features which can be stamped. In one example, a laptop cover is provided with a recess to allow a user to insert a finger to open the cover. In various examples, stamping systems allow improved stamping of metal components, such as laptop covers, with reduced surface defects. In this regard, an example stamping system includes a first stamping portion provided with a first surface having a shape which corresponds to the desired shape of the component to be stamped, such as a flat shape for the finger recess of the laptop cover. A second stamping portion is provided with a second surface to oppose the first surface. The metal component to be stamped may be positioned between the first stamping portion and the second stamping portion, with the portion of the metal component to have the desired shape positioned between the first surface and the second surface. The second surface is provided with a metal flow receiving feature which includes a non-flat surface. The non-flat surface allows the amount of metal to flow into the metal flow receiving feature to be attenuated during stamping of the metal component between the first stamping portion and the second stamping portion. For example, a stamping force may be adjusted to cause an optimal amount of metal to flow into the metal flow receiving feature to provide a substantially defect-free stamped surface on the metal component. In various examples, the non-flat surface of the metal flow receiving feature may include various shapes such as an arc or a sawtooth pattern.
- Referring first to
FIG. 1 , an example system for stamping metal components is illustrated. Theexample system 100 includes afirst stamping portion 110 and asecond stamping portion 120. Thefirst stamping portion 110 is provided with afirst surface 112. Thefirst surface 112 is shaped to form a corresponding stamped surface on a metal component to be stamped (not shown inFIG. 1 ). In this regard, thefirst surface 112 of thefirst stamping portion 110 is formed to any shape that may be desirable for the stamped surface of the metal component. In the example ofFIG. 1 , thefirst surface 112 of thefirst stamping portion 110 is shown as a substantially flat or linear surface. - The
second stamping portion 120 is provided with asecond surface 122 to oppose thefirst surface 112 of thefirst stamping portion 110 during stamping of the metal component, with the metal component being positioned between thefirst surface 112 of thefirst stamping portion 110 and thesecond surface 122 of thesecond stamping portion 120. In various examples, thesecond surface 122 of thesecond stamping portion 120 includes a metalflow receiving feature 124. The metalflow receiving feature 124 includes a non-flat surface to attenuate an amount of metal flowing therein during stamping of the metal component between thefirst stamping portion 110 and thesecond stamping portion 120. In this regard, thefirst surface 112 of thefirst stamping portion 110 produces a desired shape, while any variations in the amount of metal that is flowed as a result of the stamping is attenuated on the opposite side of the metal component. In some examples, the amount of metal flowing into the metalflow receiving feature 124 can vary based on the stamping pressure, while thefirst surface 112 of the first stamping portion produces a consistent amount of flow on the stamped side of the metal component. - The
first stamping portion 110 and thesecond stamping portion 120 of theexample system 100 may be formed of any of a variety of materials. In one example, thefirst stamping portion 110 and thesecond stamping portion 120 are each formed of steel. Generally, thefirst stamping portion 110 and thesecond stamping portion 120 may be formed of a material having a hardness that is greater than the hardness of the metal component to be stamped. - Referring now to
FIG. 2 , another example system for stampingmetal components 200 is illustrated. Theexample system 200 ofFIG. 2 is similar to theexample system 100 described above with reference toFIG. 1 and includes afirst stamping portion 210 and asecond stamping portion 220. Theexample system 200 ofFIG. 2 includes ametal component 230 to be stamped. As illustrated inFIG. 2 , themetal component 230 may form a surface of an electronic device, such as a laptop, for example. Theexample metal component 230 ofFIG. 2 is provided with asurface feature 238 which may be, for example, a finger recess to allow a user to open a closed laptop. In this regard, thesurface feature 238 should be smooth to the touch of a user. It is noted thatFIG. 2A illustrates a completed (e.g., stamped)metal component 230, whileFIG. 2B illustrates a cross-sectional view of thecomponent 230 before it is stamped. - As with the
example system 100 ofFIG. 1 , thefirst stamping portion 210 ofexample system 200 ofFIG. 2 is provided with afirst surface 212 formed to correspond to a stampedsurface 232 of themetal component 230 to be stamped. Thus, thefirst surface 212 is formed to the desired shape for the stampedsurface 232 of themetal component 230 illustrated inFIG. 2A . In this regard, thefirst surface 212 of thefirst stamping portion 210 includes a substantially flat portion. - The
second stamping portion 220 is provided with asecond surface 222, and themetal component 230 is positioned between thefirst surface 212 of thefirst stamping portion 210 and thesecond surface 222 of thesecond stamping portion 220. As noted above, themetal component 230 includes a stampedsurface 232 to be stamped. As illustrated inFIG. 2B , the stampedsurface 232 of themetal component 230 faces thefirst surface 212 of thefirst stamping portion 210. The metal component further includes a non-stampedsurface 234 opposite the stampedsurface 232. Thenon-stamped surface 234 faces thesecond surface 222 of thesecond stamping portion 220. - In the
example system 200 ofFIG. 2 , thesecond surface 222 of thesecond stamping portion 220 includes a metalflow receiving feature 224 which includes a non-flat surface. As noted above, the non-flat surface of the metalflow receiving feature 224 allows attenuation of the amount of metal flowing therein during stamping of the metal component between thefirst stamping portion 210 and thesecond stamping portion 220. In this regard, thefirst surface 212 of thefirst stamping portion 210 produces a desired shape (e.g., the flat shape illustrated inFIG. 2 ), while any variations in the amount of metal that is flowed as a result of the stamping is attenuated on the opposite side of the metal component. - Referring now to
FIGS. 3-5 , various phases of the stamping of themetal component 230 using theexample system 200 ofFIG. 2 are illustrated. As illustrated inFIGS. 3-5 , thefirst stamping portion 210 and thesecond stamping portion 220 are moved toward each other until the stamping is complete. In various examples, the completion of the stamping may occur when thefirst stamping portion 210 and the stampingportion 220 are no longer in movement relative to each other when a certain stamping pressure is applied. In this regard, the level of stamping pressure may be determined by any of a variety of factors including, but not limited to, the material of themetal component 230, tool damage prevention, accuracy, and smooth motion. - Referring first to
FIG. 3 , theexample system 200 is illustrated as a snapshot at a point at which thefirst stamping portion 210 and thesecond stamping portion 220 both make contact with themetal component 230. In the example ofFIG. 3 , at this point, thefirst surface 212 of thefirst stamping portion 210 is in contact with themetal component 230. At this point, themetal component 230 may offer resistance to the relative movement of thefirst stamping portion 210 and thesecond stamping portion 220, and sufficient stamping pressure may be used to overcome the resistance and continue to move thefirst stamping portion 210 and thesecond stamping portion 220 towards each other. - Referring now to
FIG. 4 , theexample system 200 is illustrated as a snapshot at a point at which thefirst stamping portion 210 and thesecond stamping portion 220 continue to move toward each other and deform themetal component 230. As illustrated inFIG. 4 , themetal component 230, or the stampedsurface 232 thereof, is beginning to acquire the shape of thefirst surface 212 of thefirst stamping portion 210. - Referring now to
FIG. 5 , theexample system 200 is illustrated as a snapshot at a point at which thefirst stamping portion 210 and thesecond stamping portion 220 have stopped moving toward each other. As noted above, this stoppage point may be determined by the amount of stamping pressure applied. At this stoppage point, thefirst surface 212 of thefirst stamping portion 210 forms a substantially identical surface on the stampedsurface 232 of themetal component 230. At the same time, the metalflow receiving feature 224 of thesecond surface 222 of thesecond stamping portion 220 may accommodate any variations or imperfections in the amount of metal flowing during the stamping process. - In this regard, the non-linear or non-flat surface of the metal
flow receiving feature 224 provides regions in which excess metal can flow during stamping. Similarly, the non-flat surface can accommodate varying amounts of metal flowing with variations in stamping pressure. For example, once a minimum level of stamping is achieved to sufficiently form the stampedsurface 232 of themetal component 230, additional stamping pressure may result in additional metal flowing into the non-flat metalflow receiving feature 224 while maintaining the desired stampedsurface 232. Thus, thenon-stamped surface 234 of the metal component may or may not significantly match thesecond surface 222 of thesecond stamping portion 220. -
FIGS. 1-5 illustrate various examples of stamping systems with a metal flow receiving feature corresponding to a non-stamped surface of a metal component. In theexample systems flow receiving feature 224 is illustrated as a non-linear or non-flat surface, having a non-linear cross-section, such as an arc. In other examples, the metalflow receiving feature 224 may have any of a variety of other non-linear or non-flat surfaces. In this regard,FIGS. 6 and 7 illustrate some example systems with different metal flow receiving features 224. - Referring first to
FIG. 6 , theexample system 600 includes afirst stamping portion 610, asecond stamping portion 620 and ametal component 630 being stamped therebetween. Similar to the example systems described above, thefirst stamping portion 610 of theexample system 600 includes afirst surface 612 formed to correspond to a stampedsurface 632 of themetal component 630. - The
second stamping portion 620 is provided with asecond surface 622, and themetal component 630 is positioned between thefirst surface 612 of thefirst stamping portion 610 and thesecond surface 622 of thesecond stamping portion 620. The metal component includes a stampedsurface 632 facing thefirst surface 612 of thefirst stamping portion 610 and anon-stamped surface 634, opposite the stampedsurface 632, and facing thesecond surface 622 of thesecond stamping portion 620. - In the
example system 600 ofFIG. 6 , thesecond surface 622 of thesecond stamping portion 620 includes a metalflow receiving feature 624 which includes a non-flat surface. In theexample system 600 ofFIG. 6 , the metalflow receiving feature 624 is provided with a waved formation. Viewed in three-dimensions, the metalflow receiving feature 624 may include a series of crests and troughs. During stamping, the crests may contact themetal component 630 and transmit the stamping pressure onto themetal component 630, while the troughs may provide space for a variable amount of metal to flow into. Thus, the metal flow into the metalflow receiving feature 624 may absorb any imperfections in the stamping process, thereby producing a more uniform surface on the stampedsurface 232 of the metal component. - Referring next to
FIG. 7 , theexample system 700 includes afirst stamping portion 710, asecond stamping portion 720 and ametal component 730 being stamped therebetween. Similar to the example systems described above, thefirst stamping portion 710 of theexample system 700 includes afirst surface 712 formed to correspond to a stampedsurface 732 of themetal component 730. - The
second stamping portion 720 is provided with asecond surface 722, and themetal component 730 is positioned between thefirst surface 712 of thefirst stamping portion 710 and thesecond surface 722 of thesecond stamping portion 720. The metal component includes a stampedsurface 732 facing thefirst surface 712 of thefirst stamping portion 710 and anon-stamped surface 734 opposite the stampedsurface 732 and facing thesecond surface 722 of thesecond stamping portion 720. - In the
example system 700 ofFIG. 7 , thesecond surface 722 of thesecond stamping portion 720 includes a metalflow receiving feature 724 which includes a non-flat surface. In theexample system 700 ofFIG. 7 , the metalflow receiving feature 724 is provided with a sawtooth pattern. During stamping, the sawtooth pattern can simultaneously provide the force on the metal components resulting from the stamping pressure and space for a variable amount of metal to flow into. Thus, the metal flow into the metalflow receiving feature 724 may absorb any imperfections in the stamping process, thereby producing a more uniform surface on the stampedsurface 732 of the metal component. - Referring now to
FIG. 8 , a flow chart illustrating an example method for stamping of metal components is provided. Theexample method 800 includes positioning a metal component between a first stamping portion and a second stamping portion (block 810). In various examples, the metal component has a stamped surface to be stamped and a non-stamped surface opposite the stamped surface. Further, the first stamping portion has a first surface facing the stamped surface of the metal component, and the second stamping portion has a second surface facing the non-stamped surface of the metal component. The second surface of the second stamping portion includes a metal flow receiving feature. As described above, various examples of the metal flow receiving feature may have a non-flat feature, such as a wave formation or a sawtooth formation, for example. - The
example method 800 further includes stamping the metal component between the first stamping portion and the second stamping portion (block 820). As described above, the stamping includes flowing material from the metal component into the metal flow receiving feature. In this regard, the metal flow receiving feature can absorb imperfections, thus allowing the stamped surface to be substantially defect-free. - The foregoing description of various examples has been presented for purposes of illustration and description. The foregoing description is not intended to be exhaustive or limiting to the examples disclosed, and modifications and variations are possible in light of the above teachings or may be acquired from practice of various examples. The examples discussed herein were chosen and described in order to explain the principles and the nature of various examples of the present disclosure and its practical application to enable one skilled in the art to utilize the present disclosure in various examples and with various modifications as are suited to the particular use contemplated. The features of the examples described herein may be combined in all possible combinations of methods, apparatus, modules, systems, and computer program products.
- It is also noted herein that while the above describes examples, these descriptions should not be viewed in a limiting sense. Rather, there are several variations and modifications which may be made without departing from the scope as defined in the appended claims.
