Definitions
- the present invention relates to a method and apparatus for forming profiled articles, the profiled articles being generally irregular in their body profile.
- the invention relates to a method and apparatus in which at least one body forming die block is employed to form at least part of the profiled article.
- the invention is thought to provide an alternative to current stamping techniques.
- Known systems for forming deformable materials such as sheet metal into a desired profile, particularly a desired uniform profile include roll forming processes. These processes involve passing the sheet metal through a sequence of roll sets, each further deforming the sheet beyond the profile achieved at the previous roll set.
- the disadvantages of roll forming include redundant deformation resulting from non-uniform strain paths as the strip passes each roll set. This in turn leads to high residual stresses which result in product defects such as edge wave, flare, twist, and so on.
- Another disadvantage of roll forming is that the distance between the first roll set and the last roll set is relatively large. Consequently, the space needed to house a roll forming assembly is substantial, particularly when forming complex profiles.
- a further disadvantage of roll forming is that tooling design is related to the designer's experience. "Trial and error ' plays a dominant role in tooling design and alignment and for a new complex profile tooling design, this means the development time is less predictable. Additionally a large amount of material can be wasted during the period of tooling design and alignment, which contributes to the cost of tooling development.
- chain-die forming has been proposed as an alternative in the production of articles having uniform profiles. Chain-die forming may be considered an extension of roll forming that involves forming the product gradually through at least one pass through a plurality of relatively short die blocks that incrementally form a blank into a final uniform profiled article.
- stamping which is also known as pressing, generally includes a variety of sheet-metal forming manufacturing processes. For example, this may include punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. Stamping may involve a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or may alternatively involve a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene.
- Stamping generally have earring that needs to be trimmed off after the stamping process, resulting in wasted material and additional processing time. Stamping is also discontinuous and requires a blank-holder to hold the blank in place during processing.
- the present invention aims to provide an alternative to the aforementioned forming techniques, for the production of articles which may be irregular in profile.
- the subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one exemplary technology area where some embodiments described herein may be practice.
- the present invention relates to a method and apparatus for forming profiled articles, the profiled articles being generally irregular in their body profile.
- the invention relates to a method and apparatus in which at least one body forming die block is employed to form at least part of the profiled article.
- One aspect of the present invention provides an apparatus for forming a profiled article comprising:
- pair of body forming die members is adapted to act on the blank of deformable material independently to form a desired profile on the blank.
- the apparatus may comprise any number of pairs of body forming die members, or a single pair of body forming die members.
- the apparatus comprises a plurality of pairs of body forming die members, each pair of body forming die members being adapted to act on a respective blank of deformable material independently to form a desired profile on each respective blank.
- neighbouring body forming die members of the plurality of pairs of body forming die members are generally hingedly connected to one another.
- neighbouring body forming die members are hingedly connected with minimal clearance therebetween. This ensures a relatively strong structure and a simplified structure compared with, for example, chain-die forming.
- the apparatus comprises locating elements mounted between adjacent body forming die members, the locating elements being adapted to locate the blanks prior to engagement of the blanks with the body forming die members.
- adjacent blanks may be connected to one another with a web and the locating elements may be disposed between adjacent body forming die members on a lower section of the forming path and, in use, locate on one or both sides of respective webs.
- an upper section of the forming path comprises gaps between adjacent body forming die members, the gaps cooperating with and receiving respective locating elements in use.

- the apparatus will comprise at least one additional forming path along which a respective pair of the at least one additional pair of body forming die members travels.
- the pair of body forming die members is of a length substantially equivalent to that of the blank of deformable material and acts along the length of the blank. That is, the body forming die members effectively "stamp" the length of the blank with the desired profile.

- the pair of body forming die members is of a length substantially equivalent to that of the blank of deformable material and acts along the length of the blank.
- blanks having a length of from about 100mm to 3,000mm will be suitable for use in the method, although the invention is not bound to these dimensions.
- a length of deformable material for use with an apparatus as described above, specifically an apparatus that comprises locating elements mounted between adjacent body forming die members, the locating elements being adapted to locate the blanks prior to engagement of the blanks with the body forming die members.
- the length of material of this aspect of the invention comprises a plurality of blanks of the deformable material, wherein consecutive blanks of the length of deformable material are connected to one another by a web of material, the web and the consecutive blanks defining recesses adapted to engage the locating elements of the apparatus.
- the blanks and webs may be formed from the same material or different materials and may be connected or joined together by ay suitable means.

- a profiled article formed using the apparatus or method of the invention.
- FIG. 1 illustrates the method of an embodiment of the invention in which a number of body forming die blocks are used to form an irregular profiled article.
- FIG. 2 illustrates a blank used in the method illustrated in Figure 1.
- FIG. 3 illustrates the profiled article produced by the method illustrated in Figure 1 .
- FIG. 4 illustrates an apparatus according to an embodiment of the invention including a number of body forming die blocks.
- FIG. 5 illustrates a pair of irregular body forming die blocks.
- FIG. 6 illustrates an alternative arrangement for an apparatus and method of an embodiment of the invention.
- FIGS. 7 and 8 illustrate an embodiment of the apparatus of the invention showing locating pins for locating a run of blanks.
- FIGS. 9a-9c illustrate drive arrangements for the apparatus of embodiments of the invention.
- FIGS. 10a-10c illustrate profiles for forming surfaces of apparatuses according to embodiments of the invention, along which body forming die blocks travel.
- the present invention relates to a method and apparatus for forming profiled articles, the profiled articles being generally irregular in their body profile.
- the invention relates to a method and apparatus in which at least one body forming die block is employed to form at least part of the profiled article.
- FIG 1 a simplified diagram of a forming method 10 from a blank 1 1 (as shown in Figure 2) to a final product 12 (shown in Figure 3) is illustrated.
- the blank 1 1 experiences 'n' forming passes through body forming die block pairs 13 to gradually achieve the final product 12.
- the proposed method 10 differs to conventional stamping, which can form the final product in a single stroke, as the proposed method 10 involved rolling of the blank 1 1 between the die block pairs 13. This does not require a blank-holder, as is the case with stamping, and does not result in the need to trim off earring.
- each of the die block pairs 13 imparts a desired profile to the blank 1 1 .
- Each die block pair 13 acts on the blank 1 1 to facilitate production of a final product 12 having an irregular profile.
- the proposed method 10 employs whole body forming die blocks 13 instead of discrete die-blocks seen in chain-die forming. It is considered that the use of whole body forming die blocks 13 in the proposed method 10 advantageously ensures that the forming dies have higher strengths than those used in chain-die forming and are free of gaps between the dies. As such, it is envisaged that the surface finish of the final product 12 will be improved. Also, from the mechanical implementation stand point, the structure of the apparatus, discussed below, is simpler and much more robust compared with chain-die forming.
- the apparatus 40 includes a forming path 41 disposed between a first mount 42 and a second mount 43. Additional mounts may be provided, although this will not be described here in any detail.
- the first and second mounts 42, 43 include drive gears 44, 44' that engage cooperating first die members 45 and second die members 45' respectively.
- the first and second mounts 42, 43 may form endless paths (e.g. these may be large radii elliptical mounts) or large radii semi-elliptical mounts. Blanks of deformable material travel along the forming path 41 between the cooperating first and second die members 45, 45' to form final products 46.
- Each pair of cooperating first and second die members 45, 45' acts on a respective blank to impart the characteristics of the pairs of die members 45, 45' to the blank.
- each pair of die members 45, 45' acts as a whole body die block that acts on the length of a respective blank independent of any subsequent processing with further die pairs. Therefore, the pairs of die members 45, 45' do not act in a similar way to die pairs in chain-die forming, in which a length of deformable material is sequentially deformed to a desired cross- sectional profile. Rather, the pairs of die members 45, 45' effectively act in a similar way to a conventional stamping mechanism. As illustrated, the profiles of the pairs of die members 45, 45' act independently on a respective blank to form this into the desired profile of the final product 46, which may be generally irregular or may be uniform.
- the die members 45, 45' are of relatively high strength compared with, for example, conventional chain-die blocks used in the forming of generally uniform profiles.
- the arrangement also prevents or ameliorates issues relating to earring generally associated with stamping processes. It is envisaged that the arrangement will also result in better quality finishes in the final product 46.
- Examples of the die members 45, 45' are provided in figure 5. Referring to this figure, the first die member 45 includes a first profile 55 and the second die member 45' includes a second profile 55'.
- the first and second profiles 55, 55' are complementary and impart a desired profile to the final product as the blank or intermediate passes between the pair of die members 45, 45'.
- the pair of die members 45, 45' draws a blank 61 into the apparatus 60 and moves the blank 61 forward 62 to facilitate forming.
- the final product 63 is produced and the apparatus 60 reverses and moves the die members 45, 45' backwards 64 and returns to the start position.
- FIGS 7 and 8 A preferred embodiment of the apparatus of the invention is illustrated in figures 7 and 8. Referring to these figures, the apparatus 70 is substantially as described above in that a blank 71 of deformable material is passed between sets of die members 45, 45' to form a final product 73.
- the apparatus 70 includes locating pins 75 on one side or on opposing sides of the die members 45, 45', generally located in lower gaps between the die members 45, 45' and in cooperation with upper gaps 77 between the die members 45, 45'.
- the locating pins 75 engage recesses 76 between blanks 71 , the blanks 71 in this embodiment being joined by webs 78. This advantageously ensures that the blanks 71 are correctly positioned between respective die members 45, 45' as they pass through the apparatus 70.
- die members 45, 45' act independently on a respective blank 71 passing through the apparatus 70.
- Figures 9a to 9c show some exemplary ways in which the apparatus 90 can operate.
- FIG 9a the system is provided with driving gears 91 which drive the two sets of die elements 45, 45' in phase so as to draw a section through the forming portion.
- driving gears 91 which drive the two sets of die elements 45, 45' in phase so as to draw a section through the forming portion.
- a separate set of driving rolls 92 is provided to propel this section through the forming portion.
- Figure 9c shows a similar configuration in which a separate set of driving rolls 93 are used to push a section through the forming portion.
- Figures 10a to 10c show some of the possible configurations of the forming path in the forming portion of the apparatus.
- each of the opposed forming portions has a large radius and the centres of the radii are respectively on the opposite sides of the forming space.
- Figure 10b shows a configuration in which one of the forming portions has a large radius and another has an infinite radius or in other words is flat.
- Figure 10c shows a configuration in which the centres of the radii are both on one side of the forming space and large radii are used for the respective forming portions to provide converging paths between the opposed dies. It is also considered that a configuration may be provided in which the radii of the forming portion are not constant, for example to provide a converging track between the opposed dies.
