Description

Technical Field

[0001] This invention relates to the field of diffusion bonding forming technology, specifically to a diffusion bonding forming device for complex titanium alloy irregular parts. Background Technology

[0002] Superplastic forming (SPF) / diffusion bonding (DB) technology is a combined process integrating superplastic forming and diffusion bonding. It requires materials to have similar forming and bonding temperatures, completing both SPF and DB processes in a single heating cycle. Superplastic forming / diffusion bonding structures come in various forms, conventionally classified by the number of layers in the blank sheet. There are single-layer superplastic forming (SPF) reinforcing components, as well as double-layer, triple-layer, and quadruple-layer superplastic forming (SPF) / diffusion bonding (DB) structures. These components can be widely used in large and complex titanium structural parts for aircraft, such as wing leading edges, slats, various load-bearing panels, and missile wings, covering a wide range of applications. It offers unparalleled advantages over traditional manufacturing processes in improving aircraft performance, reducing structural component weight, and lowering manufacturing costs.

[0003] Superplastic forming (SPF) and diffusion bonding (DB) technologies, driven by the development of the modern aerospace industry, have entered the practical application stage after more than 30 years of development, research, and verification testing. SPF / DB technologies have become advanced manufacturing technologies that drive the development of modern aerospace structural design concepts and break through traditional sheet metal forming methods.

[0004] Currently, most forming equipment on the market uses fixed-position heating when heating the mold and the titanium alloy parts inside the mold. This is not convenient for rotating and heating the titanium alloy parts evenly, which can easily lead to uneven heating of the titanium alloy parts, affecting the forming quality and efficiency of the titanium alloy parts. In addition, existing forming equipment lacks an ejection mechanism, making it difficult to remove the titanium alloy parts from the mold during unloading, which reduces the processing efficiency of titanium alloy parts. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a diffusion bonding forming device for complex titanium alloy irregular parts. This device solves the problems of existing forming equipment not being convenient for rotating and uniformly heating titanium alloy parts, which easily leads to uneven heating of titanium alloy parts, affecting the forming quality and efficiency of titanium alloy parts. Furthermore, existing forming equipment lacks an ejection mechanism, making it difficult to remove titanium alloy parts from the mold during material unloading, thus reducing the processing efficiency of titanium alloy parts.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a diffusion bonding forming device for complex titanium alloy irregular parts, comprising a frame, two slide rails fixedly mounted on the top of the frame, at least two sets of moving plates slidably connected between the tops of the two slide rails, a furnace base fixedly mounted on the top of the moving plates, a first sliding assembly disposed at the middle position of the top of the furnace base, a lower mold disposed on the top of the first sliding assembly, a device cavity being opened inside the lower mold, and an ejection mechanism being disposed inside the device cavity;

[0009] The bottom of the movable plate is provided with a first drive assembly, and the top of the frame and located between the two sets of slide rails is provided with a second drive assembly.

[0010] A gantry frame is fixedly installed between the front and back of the frame. A lifting mechanism is provided on the top of the gantry frame. A second sliding assembly is provided on both the front and back of the inner wall of the gantry frame. A furnace hood is provided between the two sets of second sliding assemblies. An upper mold that matches the lower mold is rotatably connected to the top of the inner wall of the furnace hood. A control switch is fixedly installed on the top of the frame. An annular overlapping groove is provided on the top of the furnace base and outside the first sliding assembly.

[0011] Preferably, heating plates are fixedly embedded on both sides of the inner wall of the furnace hood, positioning grooves are opened at the four corners of the top of the lower mold, and positioning posts that are compatible with the positioning grooves are fixedly connected to the four corners of the bottom of the upper mold. The bottom end of the positioning post is embedded in the inside of the positioning groove. Through the cooperation of the positioning post and the positioning groove, the upper mold can be limited, so that when the lower mold is driven to rotate by the first drive component, the upper mold can be indirectly driven to rotate on the top of the inner wall of the furnace hood.

[0012] Preferably, the first sliding assembly includes an annular slide rail fixedly installed on the top of the furnace base. A plurality of first sliders are slidably connected inside the annular slide rail. The top of the first sliders is fixedly connected to the bottom of the lower mold. The arrangement of the annular slide rail and the first sliders can improve the stability and smoothness of the lower mold during rotation.

[0013] Preferably, the ejection mechanism includes a double-headed electric telescopic rod fixedly installed at the bottom center of the inner wall of the device cavity. Movable blocks are fixedly connected to both ends of the double-headed electric telescopic rod. A connecting rod is hinged to the top of each movable block, and a movable plate is hinged to the other end of the connecting rod. Several ejection rods arranged in a rectangular array are fixedly connected to the top of the movable plate. By extending both ends of the double-headed electric telescopic rod, two movable blocks can be moved to opposite sides, which in turn causes the movable plate to move upward via the connecting rod, thereby causing the ejection rods to move upward. This ejection force pushes the complex titanium alloy shaped parts, after heat forming in the lower mold, upward, facilitating the unloading of the complex titanium alloy shaped parts from the lower mold and effectively improving the unloading rate of complex titanium alloy shaped parts.

[0014] Preferably, the top of the inner wall of the device cavity is provided with a plurality of through holes arranged in a rectangular array, and a plurality of ejector rods are provided in a one-to-one correspondence with a plurality of through holes, and the top of the ejector rods penetrates and extends into the interior of the through holes, the movable plate is slidably connected between the two sides of the inner wall of the device cavity, and the movable block is slidably connected to the bottom of the inner wall of the device cavity.

[0015] Preferably, the first driving component includes a low-speed motor fixedly installed at the bottom center of the movable plate. The output end of the low-speed motor is fixedly connected to a rotating shaft (not shown in the figure), and the other end of the rotating shaft (not shown in the figure) is fixedly connected to the bottom of the lower mold. By setting the first driving component, the lower mold, the upper mold, and the complex titanium alloy shaped parts inside the lower mold can be driven to rotate synchronously at low speed inside the furnace hood. This allows the heating plates on the inner wall of the furnace hood to perform rotary heating on the upper mold, the lower mold, and the complex titanium alloy shaped parts between the two molds. This facilitates uniform heating of the complex titanium alloy shaped parts and ensures the uniformity of heating of the complex titanium alloy shaped parts between the upper mold, the lower mold, and the two molds, thereby effectively improving the forming effect of the complex titanium alloy shaped parts.

[0016] Preferably, the second drive assembly includes a drive motor fixedly mounted on the top of the frame. The output end of the drive motor is fixedly connected to a first threaded rod, and the other end of the first threaded rod is fixedly connected to a first limiting block. Two first threaded blocks are threadedly connected to the outer surface of the first threaded rod. The tops of the two first threaded blocks are fixedly connected to the bottoms of the two moving plates respectively. The rotation of the drive motor drives the first threaded rod to rotate, thereby driving the two first threaded blocks threadedly connected to the outer surface to rotate, and thus driving the moving plates, furnace base, and lower mold mounted on the furnace base to move.

[0017] Preferably, the second sliding component includes a groove formed on the inner wall of the gantry frame, and a second slider is slidably connected inside the groove. The side of the second slider away from the groove is fixedly connected to the outer wall of the furnace hood. Through the cooperation of the groove and the second slider, the furnace hood can be limited and the stability of the furnace hood when moving up and down can be improved.

A second threaded rod is threadedly connected inside the second threaded block. A second limiting block is fixedly connected to the top of the second threaded rod. The bottom end of the second threaded rod is fixedly connected to the top of the furnace hood. The fixed motor is fixedly installed on the top of the inner wall of the gantry frame. The fixed motor is used to drive the drive gear to rotate, thereby indirectly driving the second threaded rod to move.

[0019] Preferably, the output end of the fixed motor is fixedly connected to a drive gear, and the outer surface of the second threaded block is fixedly fitted with a driven gear that meshes with the drive gear. Through the cooperation of the drive gear and the driven gear meshing with it, the kinetic energy of the output end of the fixed motor is transmitted to the second threaded block, thereby indirectly driving the second threaded rod to move along the axial direction of the second threaded block, thereby indirectly realizing the up and down lifting of the furnace hood.

[0020] (III) Beneficial Effects

[0021] This invention provides a diffusion bonding forming device for complex titanium alloy irregular-shaped parts. It has the following beneficial effects:

[0022] 1. Compared with existing technologies, this complex titanium alloy shaped parts diffusion connection forming equipment uses a low-speed motor to drive a rotating shaft (not shown in the figure) to rotate. This causes the lower mold, upper mold, and the complex titanium alloy shaped parts inside the lower mold to rotate synchronously at low speed within the furnace hood. The heating plates on the inner wall of the furnace hood then provide rotary heating to the upper mold, lower mold, and the complex titanium alloy shaped parts between the two molds. This facilitates uniform heating of the complex titanium alloy shaped parts, ensuring the uniformity of heating of the upper mold, lower mold, and the complex titanium alloy shaped parts between the two molds, thereby effectively improving the forming effect of complex titanium alloy shaped parts.

[0023] 2. Compared with existing technologies, this complex titanium alloy shaped parts diffusion connection forming equipment, through the arrangement of at least two sets of moving plates, furnace bases, lower molds, and second drive components, facilitates the separate heating and forming, unloading, and loading operations of complex titanium alloy shaped parts. Furthermore, through the coordinated use of a lifting mechanism and a second sliding component, the furnace hood can be driven up and down to transfer the furnace base and the lower mold mounted on it. This allows for the simultaneous heating and forming of complex titanium alloy shaped parts in the lower molds of one set of furnace bases, while the operator can sequentially unload and load the complex titanium alloy shaped parts in the lower molds of another set that have already undergone heating and forming. This ensures that the heating, forming, unloading, and loading operations of complex titanium alloy shaped parts do not interfere with each other, thereby improving production efficiency.

[0024] 3. Compared with existing technologies, this complex titanium alloy irregular part diffusion connection forming equipment, by activating the double-headed electric telescopic rod, extends both ends of the double-headed electric telescopic rod, thereby driving two movable blocks to move to opposite sides. Then, through the connecting rod, the movable plate moves upward, thereby driving several ejector rods to move upward. Finally, the ejector rods push the complex titanium alloy irregular part, which has been heated and formed in the lower mold, upward, making it easier for workers to unload the complex titanium alloy irregular part in the lower mold and effectively improving the unloading rate of complex titanium alloy irregular parts.

[0025] 4. Compared with existing technologies, this complex titanium alloy irregular part diffusion connection forming equipment improves the stability and smoothness of the lower mold rotation by setting an annular slide rail and a first slider.

[0026] 5. Compared with the existing technology, the diffusion connection forming equipment for complex titanium alloy irregular parts can limit the furnace hood by using the cooperation of the slide groove and the second slider, and can improve the stability of the furnace hood when it moves up and down.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example:

[0037] like Figure 1-7As shown, this embodiment of the invention provides a diffusion bonding forming device for complex titanium alloy irregular parts, including a frame 1. Two slide rails 2 are fixedly installed on the top of the frame 1. At least two sets of moving plates 3 are slidably connected between the tops of the two slide rails 2. The slide rails 2 can limit the movement of the moving plates 3 and improve the stability of the moving plates 3 when they move. A furnace base 4 is fixedly installed on the top of the moving plates 3. A first sliding component is provided at the middle position of the top of the furnace base 4. A lower mold 5 is provided on the top of the first sliding component. A device cavity 6 is opened inside the lower mold 5. The device cavity 6 is used to install an ejection mechanism. The ejection mechanism is provided inside the device cavity 6.

[0038] The bottom of the movable plate 3 is provided with a first drive assembly, and the top of the frame 1 and located between the two sets of slide rails 2 is provided with a second drive assembly.

[0039] A gantry frame 7 is fixedly installed between the front and back of the frame 1. A lifting mechanism is provided on the top of the gantry frame 7. The gantry frame 7 is used to support the lifting mechanism and the furnace hood 8. A second sliding assembly is provided on both the front and back of the inner wall of the gantry frame 7. The furnace hood 8 is provided between the two sets of second sliding assemblies. An upper mold 9 that matches the lower mold 5 is rotatably connected to the top of the inner wall of the furnace hood 8. A control switch 32 is fixedly installed on the top of the frame 1. An annular overlapping groove 33 is opened on the top of the furnace base 4 and outside the first sliding assembly. The bottom end of the furnace hood 8 is inserted into the annular overlapping groove 33 on the top of one of the furnace bases 4, and the furnace hood 8 matches the annular overlapping groove 33. The furnace hood 8 is connected by at least two sets of moving plates 3, furnace bases 4, lower molds 5 and a second drive group. The structure is designed to facilitate the separate heating, forming, unloading, and loading of complex titanium alloy shaped parts. Through the coordinated use of the lifting mechanism and the second sliding component, the furnace hood 8 can be driven to move up and down, allowing for the transfer of the furnace base 4 and the lower mold 5 mounted on it. This ensures that while one set of complex titanium alloy shaped parts in the lower mold 5 at the top of the furnace base 4 is being heated and formed, the operator can simultaneously unload and load the other set of complex titanium alloy shaped parts in the lower mold 5 that has already undergone heating and forming. This ensures that the heating, forming, unloading, and loading operations of complex titanium alloy shaped parts do not interfere with each other, thereby improving production efficiency.

[0040] Heating plates 10 are fixedly embedded on both sides of the inner wall of the furnace cover 8. The heating plates 10 are used to heat the upper mold 9, lower mold 5 and complex titanium alloy irregular parts located between the two molds inside the furnace cover 8. The four corners of the top of the lower mold 5 are provided with positioning grooves 11. The four corners of the bottom of the upper mold 9 are fixedly connected with positioning posts 12 that are adapted to the positioning grooves 11. The bottom end of the positioning post 12 is embedded in the inside of the positioning groove 11. Through the cooperation of the positioning post 12 and the positioning groove 11, the upper mold 9 can be limited, so that when the lower mold 5 is driven to rotate by the first drive component, the upper mold 9 can be indirectly driven to rotate on the top of the inner wall of the furnace cover 8.

[0041] The first sliding assembly includes an annular slide rail 13 fixedly installed on the top of the furnace base 4. Several first sliders 14 are slidably connected inside the annular slide rail 13. The top of the first sliders 14 is fixedly connected to the bottom of the lower mold 5. The arrangement of the annular slide rail 13 and the first sliders 14 can improve the stability and smoothness of the lower mold 5 when it rotates.

[0042] The ejection mechanism includes a double-headed electric telescopic rod 15 fixedly installed at the bottom center of the inner wall of the device cavity 6. The double-headed electric telescopic rod 15 is electrically connected to the control switch 32 and to an external power source. Movable blocks 16 are fixedly connected to both ends of the double-headed electric telescopic rod 15. A connecting rod 17 is hinged to the top of the movable block 16, and a movable plate 18 is hinged to the other end of the connecting rod 17. Several ejection rods 19 arranged in a rectangular array are fixedly connected to the top of the movable plate 18. The top of the inner wall of the device cavity 6... A number of through holes 20 arranged in a rectangular array are provided. The through holes 20 facilitate the upward movement of the ejector rod 19 into the interior of the lower mold 5, thereby facilitating the ejector rod 19 to eject the complex titanium alloy irregular parts inside the lower mold 5 upward. The number of ejector rods 19 are arranged one-to-one with the number of through holes 20, and the top of the ejector rod 19 penetrates and extends into the interior of the through hole 20. The movable plate 18 is slidably connected between the two sides of the inner wall of the device cavity 6, and the movable block 16 is slidably connected to the bottom of the inner wall of the device cavity 6.

[0043] By sliding the movable block 16 and the movable plate 18 on the inner wall of the device cavity 6, the stability of the movable block 16 and the movable plate 18 during movement can be improved, effectively improving the stability and smoothness of the ejection mechanism during use.

[0044] When it is necessary to unload complex titanium alloy shaped parts from the lower mold 5 after heat forming, the double-headed electric telescopic rod 15 is activated, causing both ends of the double-headed electric telescopic rod 15 to extend, thereby driving the two movable blocks 16 to move to opposite sides. Then, the connecting rod 17 drives the movable plate 18 to move upward, thereby driving several ejector rods 19 to move upward. The ejector rods 19 then push the complex titanium alloy shaped parts from the lower mold 5 upward, making it easier for workers to unload the complex titanium alloy shaped parts from the lower mold 5 and effectively improving the unloading speed of complex titanium alloy shaped parts.

[0045] The first drive assembly includes a low-speed motor 21 fixedly installed at the bottom center of the movable plate 3. The low-speed motor 21 is electrically connected to the control switch 32 and to an external power source. A rotating shaft (not shown in the figure) is fixedly connected to the output end of the low-speed motor 21. The other end of the rotating shaft (not shown in the figure) is fixedly connected to the bottom of the lower mold 5. The rotation of the output end of the low-speed motor 21 drives the rotating shaft to rotate, thereby driving the lower mold 5, the upper mold 9, and the complex titanium alloy shaped parts inside the lower mold 5 to rotate synchronously at low speed inside the furnace hood 8. The heating plate 10 on the inner wall of the furnace hood 8 then rotates the upper mold 9, the lower mold 5, and the complex titanium alloy shaped parts between the two molds to achieve rotational heating. This facilitates uniform heating of the complex titanium alloy shaped parts and ensures the uniformity of heating of the complex titanium alloy shaped parts between the upper mold 9, the lower mold 5, and the two molds, thereby effectively improving the forming effect of the complex titanium alloy shaped parts.

[0046] The second drive assembly includes a drive motor 22 fixedly mounted on the top of the frame 1. The drive motor 22 is electrically connected to the control switch 32 and to an external power source. The output end of the drive motor 22 is fixedly connected to a first threaded rod 23, and the other end of the first threaded rod 23 is fixedly connected to a first limiting block. The first limiting block can limit the first threaded block 24, effectively preventing the first threaded block 24 from detaching from the first threaded rod 23. The outer surface of the first threaded rod 23 is threadedly connected to two first threaded blocks 24. The tops of the two first threaded blocks 24 are fixedly connected to the bottoms of the two moving plates 3 respectively. The rotation of the drive motor 22 drives the first threaded rod 23 to rotate, thereby driving the two first threaded blocks 24 threadedly connected to the outer surface to rotate, and thus driving the moving plate 3, the furnace base 4, and the lower mold 5 installed on the furnace base 4 to move.

[0047] The second sliding assembly includes a groove 25 formed on the inner wall of the gantry 7. A second slider 26 is slidably connected inside the groove 25. The side of the second slider 26 away from the groove 25 is fixedly connected to the outer wall of the furnace cover 8. Through the cooperation of the groove 25 and the second slider 26, the furnace cover 8 can be limited and the stability of the furnace cover 8 when it moves up and down can be improved.

[0048] The lifting mechanism includes a second threaded block 27 and a fixed motor 28. The fixed motor 28 is electrically connected to the control switch 32 and to an external power source. The second threaded block 27 is rotatably connected to the middle position of the top of the gantry frame 7. The second threaded block 27 has a second threaded rod 31 connected to its internal thread. The top end of the second threaded rod 31 is fixedly connected to a second limiting block. The second limiting block can limit the second threaded rod 31 and effectively prevent the second threaded rod 31 from detaching from the second threaded block 27. The bottom end of the second threaded rod 31 is fixedly connected to the top of the furnace hood 8. The fixed motor 28 is fixedly installed on the top of the inner wall of the gantry frame 7. The output end of the fixed motor 28 is fixedly connected to a drive gear 29. The outer surface of the second threaded block 27 is fixedly fitted with a driven gear 30 that meshes with the drive gear 29.

[0049] By rotating the output of the fixed motor 28 in both forward and reverse directions, the driving gear 29 fixedly connected to it is driven to rotate. The rotation of the driving gear 29 drives the driven gear 30 meshing with it to rotate, which in turn drives the second threaded block 27 to rotate. This causes the second threaded rod 31, which is threaded inside the second threaded block 27, to move downward or upward, causing the furnace cover 8 to move downward or upward, thereby allowing the furnace cover 8 to abut against the furnace base 4 for use or separation.

[0050] By using the lifting mechanism and the second sliding component together, the furnace cover 8 can be driven to move up and down, which facilitates the transfer of the furnace base 4 and the lower mold 5 installed on the furnace base 4. This allows the forming equipment to heat and form complex titanium alloy shaped parts, and the unloading and loading operations do not interfere with each other, thereby improving production efficiency.

[0051] Working principle: When using this complex titanium alloy irregular part diffusion connection forming equipment to process titanium alloy parts, the complex titanium alloy irregular part to be processed is first placed in the lower mold 5. Then, the fixed motor 28 is started. The output end of the fixed motor 28 rotates forward, driving the drive gear 29 to rotate. The rotation of the drive gear 29 drives the driven gear 30 meshing with it to rotate, thereby driving the second threaded block 27 to rotate. When the second threaded block 27 rotates, under the cooperation of the slide groove 25 and the second slider 26, it plays a limiting role on the furnace cover 8, thereby indirectly limiting the second threaded rod 31. When the second threaded block 27 rotates, it drives the second threaded rod 31 to move downward, thereby realizing the downward movement of the furnace cover 8 until the furnace cover 8 abuts against the furnace base 4, and the upper mold 9 and the lower mold 5 abut against each other. The positioning post 12 at the bottom of the upper mold 9 is embedded in the positioning groove 11 at the top of the lower mold 5. Thus, the upper mold 9 and the lower mold 5 are limited by the cooperation of the positioning post 12 and the positioning groove 11.

[0052] When the upper mold 9 and the lower mold 5 come into contact, the low-speed motor 21 is started. The output end of the low-speed motor 21 rotates, driving the rotating shaft (not shown in the figure) to rotate, thereby driving the lower mold 5 to rotate. This causes the lower mold 5 to drive the first slider 14 to slide inside the annular slide rail 13. The rotation of the lower mold 5 drives the complex titanium alloy irregular parts inside the upper mold 9 and the lower mold 5 to rotate synchronously, realizing the rotational heating of the upper mold 9, the lower mold 5 and the complex titanium alloy irregular parts between the two molds. This facilitates uniform heating of the complex titanium alloy irregular parts, ensuring the uniformity of heating of the complex titanium alloy irregular parts between the upper mold 9, the lower mold 5 and the two molds, thereby effectively improving the forming effect of the complex titanium alloy irregular parts.

[0053] After the complex titanium alloy irregular part is formed, the output end of the fixed motor 28 is reversed, which drives the drive gear 29 fixedly connected to it to rotate. The rotation of the drive gear 29 drives the driven gear 30 meshing with it to rotate, which in turn drives the second threaded block 27 to rotate, causing the second threaded rod 31 connected to the thread inside the second threaded block 27 to move upward, causing the furnace cover 8 to move upward and separate from the furnace base 4.

[0054] Next, the drive motor 22 is started. The output end of the drive motor 22 rotates, which drives the first threaded rod 23 to rotate, thereby moving the two first threaded blocks 24 connected to the outer surface threaded together, which in turn moves the two moving plates 3, and moves the furnace base 4 fixedly connected to them. This moves the furnace base 4, on which the complex titanium alloy irregular part to be processed is placed, to the bottom of the furnace cover 8. Then, the output end of the fixed motor 28 rotates forward, driving the drive gear 29, the driven gear 30 and the second threaded block 27 to rotate synchronously, causing the second threaded rod 31 to move down, which moves the furnace cover 8 down to abut against the furnace base 4, so that the processed part on the furnace base 4 can be heated and formed.

[0055] By setting up at least two sets of moving plates 3, furnace base 4, lower mold 5, and second drive components, when the complex titanium alloy shaped parts in the lower mold 5 at the top of one set of furnace base 4 in the forming equipment are being heated and formed, the operator can sequentially unload and load the complex titanium alloy shaped parts in the lower mold 5 of the other set that has already been heated and formed. This ensures that the heating and forming, unloading, and loading operations of the forming equipment for complex titanium alloy shaped parts do not interfere with each other, thereby improving production efficiency.

[0056] When it is necessary to unload complex titanium alloy shaped parts from the lower mold 5 after heat forming, the double-headed electric telescopic rod 15 is activated, causing both ends of the double-headed electric telescopic rod 15 to extend, thereby driving the two movable blocks 16 to move to opposite sides. Then, the connecting rod 17 drives the movable plate 18 to move upward, thereby driving several ejector rods 19 to move upward. The ejector rods 19 then push the complex titanium alloy shaped parts from the lower mold 5 upward, making it easier for workers to unload the complex titanium alloy shaped parts from the lower mold 5 and effectively improving the unloading speed of complex titanium alloy shaped parts.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
