Description

Technical Field

[0001] This invention relates to the field of composite pressing and positioning technology, specifically to a workpiece positioning and shaping fixture for forging equipment. Background Technology

[0002] Copper-aluminum composite sheets and strips combine the excellent electrical and thermal conductivity of copper with the lightweight and low-cost characteristics of aluminum, making them highly valuable in fields such as battery connectors for new energy vehicles, power electronic busbars, and aerospace. As modern industry increasingly demands higher comprehensive mechanical properties and current transmission stability from composite materials, multilayer composite sheets and strips made of multiple thin copper and aluminum foils are gradually becoming a research hotspot in the industry due to their superior flexibility and high-frequency skin effect.

[0003] Currently, the industry commonly uses a traditional parallel flat-laying and direct pressing and positioning production process when manufacturing multilayer copper-aluminum composite sheets and strips. Existing multilayer strip pressing and positioning production equipment and processes have the following significant drawbacks: In terms of material conveying and array arrangement, during the parallel feeding and traction of multiple thin metal foils, the lack of an effective spatial guidance and tension-equalizing mechanism makes them highly susceptible to uneven tension or deviation, leading to localized wrinkles, entanglement, or edge tearing, resulting in extremely unstable front-end feeding. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a workpiece positioning and shaping fixture for forging equipment.

This allows the equipment to smoothly unfold without dead angles when adapting to different inner diameter requirements. The forced high-speed rotating spindle assembly returns to an absolutely concentric state, fundamentally preventing winding distortion or structural interference caused by axial sway in the core weaving part, and ensuring the compactness of the spiral stacking process.

[0017] 3. This invention employs a technical approach of three-dimensional spiral winding followed by physical flattening and thermal pressing for positioning. This overall working logic ensures that multiple thin copper and aluminum foils are forcibly fused together through spiral interlacing before entering the final pressing and positioning stage.

[0020] The technical solutions in 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.

[0021] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a workpiece positioning and shaping fixture for a forging equipment, comprising: a main frame 1 for fixing the workpiece positioning and shaping fixture structure of the forging equipment; a semi-enclosed cover structure is provided on the top of the main frame 1, and the cover structure is provided with a heating element located in the output direction of the main frame 1. Please see the appendix Figure 1 - Appendix Figure 3The side frame 2 is located on the main frame 1 and is used to fix the segmented input structure of copper foil and aluminum foil. The side frame 2 is fixed to the input direction side wall of the main frame 1. Please see the appendix Figure 4 - Appendix Figure 6 The segmented input mechanism 3 is located on the side frame 2 and is used to form a ring-shaped and synchronously output segmented input structure for copper foil and aluminum foil. The segmented input mechanism 3 is statically mounted on the side frame 2. Please see the appendix Figure 4 - Appendix Figure 6 The segmented input mechanism 3 includes a fixed ring frame 31 and a ring-shaped distributed segmented guide assembly. The fixed ring frame 31 is fixed on the side frame 2, and the segmented guide assembly is arranged circumferentially on the inner wall of the segmented input mechanism 3. The fixed ring frame 31 acts as a positioning center for multi-point convergence in the conveying process. When the material passes through the internal components, the fixed ring frame 31 provides circumferential uniform constraint support force based on its ring-shaped contour. After receiving the material, the segmented guide assembly distributed on the inner wall decomposes the traction action to each independent node on the circumference. During the material propulsion process, the segmented guide assembly contacts the surfaces of multiple copper foils and aluminum foils passing through, restricting each foil from sliding on the inner wall of the fixed ring frame 31, ensuring that all the raw materials distributed circumferentially converge towards the center at a completely consistent angle. Please see the appendix Figure 5 - Appendix Figure 6 The segmented guiding assembly includes a material distribution frame 32, which is circumferentially fixed to the inner ring wall of a fixed ring frame 31. Opposite pressing rollers 33 are arranged inside the material distribution frame 32 to form a centrally guided roller structure. A feeding wheel 34 is mounted on the outer input port of the material distribution frame 32, and a curved material channel 35 is fixed at the output end of the material distribution frame 32 facing the central winding mechanism 4. All curved material channels 35 are curved towards the central winding mechanism 4. The feeding wheel 34 rotates under the tension of the foil front end to release the long strip. The raw material is then inserted into the distribution frame 32. Inside the distribution frame 32, opposing pressing rollers 33 rotate relative to each other and adhere to the front and back of the foil. They use friction to bite and push the foil forward at a uniform speed, while smoothing out the wrinkles on the surface of the raw material to maintain constant tension. The foil that passes through the opposing pressing rollers 33 rushes into the curved material channel 35. The material that is moving in a straight line is guided by the curved surface as it slides against the inner wall of the curved material channel 35. The curved material channel 35 forcibly twists the straight trajectory of the material, causing the foil that is ejected from it to accurately converge towards the central winding mechanism 4.

[0022] Please see the appendix Figure 4 - Appendix Figure 8 The central winding mechanism 4 is located on the main frame 1. It works with the fixed ring frame 31 and the curved material channel 35 to form a guide structure for the synchronous spiral winding of multiple copper foils and aluminum foils. The central winding mechanism 4 is set on the main frame 1, and while maintaining the axis with the segmented input mechanism 3, it is close to the output end of the segmented input mechanism 3. Please see the appendix Figure 4 - Appendix Figure 8 The central winding mechanism 4 includes a suspended guide arm 41 and a variable pitch winding assembly. The suspended guide arm 41 is rotatably mounted on the side frame 2, and a reset spring structure is sleeved on the rotating end of the suspended guide arm 41. The variable pitch winding assembly is located at the end of the suspended guide arm 41 and is concentric with the fixed ring frame 31. The suspended guide arm 41 bears the high-speed rotational vibration of the variable pitch winding assembly and the pulling force of the material. When the uneven tension of the foil material causes the rotation axis to swing, the swing force is applied to the rotating end of the suspended guide arm 41. The reset spring structure sleeved on the rotating end of the suspended guide arm 41 undergoes elastic deformation to absorb the abnormal lateral force. As the swing force dissipates, the reset spring structure releases the elastic restoring force, forcibly pushing the suspended guide arm 41 back to its original position. The reset action of the suspended guide arm 41 then drives the variable pitch winding assembly at the end to return to the center position. Please see the appendix Figure 5 - Appendix Figure 8 The variable-pitch winding assembly includes a central drive shaft 42 and a central sleeve 45. The central drive shaft 42 rotates on the outer end of the suspension guide arm 41, and parallel traction rods 43 distributed in a circle are mounted on the central drive shaft 42. Guided by the parallel traction rods 43, the outer arc-shaped plate 44 is distributed parallel and coaxially. The central sleeve 45 is sleeved on the central drive shaft 42, and a retaining spring structure is continuously connected between the central sleeve 45 and the end of the central drive shaft 42. An adjusting traction rod 46 is hinged around the outer side of the central sleeve 45, and the outer end is hinged to the center of the corresponding parallel traction rod 43. The rotation of the drive shaft 42 transmits torque to the parallel traction rod 43, which drives the outer arc plate 44 spliced ​​into a cylindrical surface to rotate synchronously. The friction force on the surface of the outer arc plate 44 is used to wind the foil material. During adjustment, the central sleeve 45 slides axially along the outer wall of the central drive shaft 42 to overcome the resistance of the snap ring structure. This displacement pulls one end of the control traction rod 46 to move. The control traction rod 46 then deflects at an angle to push and pull the outer hinged parallel traction rod 43. The parallel traction rod 43 is forced to drive the outer arc plate 44 to expand or contract radially synchronously, thereby precisely changing the outer diameter of the wound cylindrical surface.

[0023] Please see the appendix Figure 6 - Appendix Figure 10 The polymerization and flattening mechanism 5 is located on the main frame 1 and works with the parallel traction rod 43 to receive the copper foil and aluminum foil after they are wound into a column and to perform preliminary flattening output. The polymerization and flattening mechanism 5 is mounted on the main frame 1 and is connected to the output end of the central winding mechanism 4. Please see the appendix Figure 8 - Appendix Figure 10The aggregation and flattening mechanism 5 includes a traction guide platform 51, which is fixed on the main frame 1. A lifting suspension frame 52 is fixed on the top of the traction guide platform 51. The top-fixed aggregation conduit 53 is suspended in the axial region of the fixed ring frame 31 by the lifting suspension frame 52 and docked with the external arc plate 44. The flattening conduit 54 is fixed at the output end of the aggregation conduit 53. The traction guide platform 51 bears the material pushing reaction force and provides a stable reference for the lifting suspension frame 52. The lifting suspension frame 52 bears the weight of the end component to maintain the center docking accuracy. The material that has left the center of rotation is pushed into the inner cavity of the aggregation conduit 53. The aggregation conduit 53 uses the funnel-shaped contraction inner wall to apply a radial extrusion force of equal pressure to the material in all directions, eliminate the interlayer gap and tighten the spiral structure. The tightened material enters the flattening conduit 54. The gradually changing inner wall of the flattening conduit 54 applies a strong up and down flattening stress to the columnar section.

[0024] Please see the appendix Figure 7 - Appendix Figure 9 The positioning and cutting mechanism 6 is located on the main frame 1 and works with the traction guide table 51 to form a controllable cutting segmentation structure. The positioning and cutting mechanism 6 is placed between the central winding mechanism 4 and the aggregation and flattening mechanism 5. Please see the appendix Figure 7 - Appendix Figure 9 The positioning and cutting mechanism 6 includes a counter-frame 61, which is fixed on the traction guide table 51 and placed between the central winding mechanism 4 and the aggregation and flattening mechanism 5. A belt conveyor 62 is mounted on the counter-frame 61, and a traction slide 63 is fixedly attached to one side of the belt end of the belt conveyor 62 to traction the traction slide 63 to move laterally linearly on the traction guide table 51. A cutting blade structure is set on the traction slide 63. The belt conveyor 62 drives the closed-loop belt to rotate, and the linear displacement section pulls the traction slide 63 fixed on it, so that the traction slide 63 slides linearly in the counter-frame 61 along the strip output direction. The speed of the belt conveyor 62 is adjusted so that the moving speed of the traction slide 63 reaches a relatively stationary state consistent with the strip conveying speed. During the synchronous process, the cutting blade structure mounted on the traction slide 63 extends downward and uses vertical shearing force to instantly penetrate and cut multiple layers of strip. After the cutting action is completed, the cutting blade structure is raised and reset, and the belt conveyor 62 reverses and drags the traction slide 63 back to its original position quickly.

[0025] Please see the appendix Figure 3 - Appendix Figure 10 The centralized pressing mechanism 7 is located on the main frame 1 and works with the flattening guide tube 54 for the final composite strip pressing and positioning operation. The centralized pressing mechanism 7 is set in the output area of ​​the main frame 1. Please see the appendix Figure 10The centralized pressing mechanism 7 includes an alignment frame 71, which is fixed to the output direction side wall of the main frame 1. An inclined roller frame 72 is fixed to the top of the alignment frame 71, and pressing positioning rollers 73 are mounted on the inclined roller frame 72. The relative gap area of ​​the pressing positioning rollers 73 corresponds to the output direction of the flattening guide tube 54. The alignment frame 71 withstands the huge pressing positioning vibration impact at the output end to ensure the straightness of the processing trajectory. The preheated strip is inserted into a specific inclined area of ​​the inclined roller frame 72. The inclination angle of the inclined roller frame 72 guides the strip to cut into the gap between the two relatively close pressing positioning rollers 73. The two pressing positioning rollers 73 rotate synchronously in opposite directions. The roller surface is in close contact with the surface of the strip and applies a huge vertical pressing force and tangential tensile force. Under this high pressure extrusion, the pressing positioning rollers 73 force the strip to undergo thickness reduction deformation.

[0026] Based on the above technical solution, this embodiment of the invention also provides a working principle of a workpiece positioning and shaping fixture for forging equipment, including the following: When the equipment is performing the pressing and positioning production operation of multiple copper-aluminum composite strips, multiple rolls of copper foil and aluminum foil raw materials in their initial state are respectively sleeved and loaded on the outside of each feeding wheel 34. With the overall traction start of the equipment, the feeding wheel 34 rotates under the tension of the raw material end, continuously releasing long strips of copper foil and aluminum foil. The released single strips of copper foil and aluminum foil follow their own input trajectory, pass through the input port of the corresponding material distribution frame 32, and directly enter the inner cavity of the material distribution frame 32. At this time, the opposing pressing rollers 33 set inside the material distribution frame 32 start to operate, and the two opposing pressing rollers 33 rotate relative to each other. The outer cylindrical surface is tightly fitted to the front and back surfaces of the copper and aluminum foils passing between them. The opposing pressure roller 33 applies clamping pressure perpendicular to the foil surface. Simultaneously, the rolling friction between the roller surface and the foil forces the copper and aluminum foils to move forward at a uniform speed. This clamping action not only provides the basic power for subsequent material conveying but also smooths out the fine wrinkles generated during the foil feeding process, ensuring that each copper and aluminum foil is output in a flat state under constant tension. The copper and aluminum foils passing through the opposing pressure roller 33 are then forcibly pushed into the inner cavity of the curved material channel 35. Because the inner wall of the curved material channel 35 has a specific curvature, the copper and aluminum foils, moving in a straight line, are physically limited by the inner wall as they slide against it. The curved surface guides the material, forcing its trajectory to deflect. Multiple foils that were originally parallel or divergent are precisely aligned towards the central axis of the equipment after passing through their respective curved feed channels 35. This creates a dynamic conveying array where multiple raw materials are simultaneously fed into the core area from various circumferential directions. As multiple copper and aluminum foils converge towards the center, the central winding mechanism 4 begins to perform diameter-changing and rotational winding operations. The power source drives the central drive shaft 42 to rotate at high speed and smoothly. The rotational torque of the central drive shaft 42 is synchronously transmitted to the parallel traction rods 43 and the external arc plates 44 surrounding it, causing the cylindrical shell structure formed by the multiple external arc plates 44 to... The central drive shaft 42 rotates synchronously on the same axis. During this process, in order to adapt to the needs of finished products of different specifications and sizes, the central sleeve 45 is controlled to slide linearly along the outer wall of the central drive shaft 42. When the central sleeve 45 slides, it overcomes the elastic resistance of the snap ring structure connected to it. Its displacement directly pulls one end of the outer hinged regulating traction rod 46 to move accordingly. The regulating traction rod 46 is pulled or pushed, and deflects at an angle with its hinge point as the center. The deflection torque is then transmitted to the parallel traction rod 43 hinged to the outer end of the regulating traction rod 46. After the parallel traction rod 43 is subjected to force, it drives the outer arc plate 44 connected to it to make radial expansion or contraction displacement. The multiple outer arc plates 44 move radially synchronously.This directly alters the outer diameter of the cylindrical shell formed by the overall splicing, thereby precisely setting the inner diameter reference for subsequent winding. Furthermore, during the high-speed rotation of the entire variable-pitch winding assembly driven by the central drive shaft 42, the suspension guide arm 41 bears the cantilever weight of the entire assembly and the centrifugal vibration during operation. The reset spring structure sleeved at the rotating end of the suspension guide arm 41 plays a dynamic balancing role at this moment. When a slight imbalance occurs in the tension of multiple copper and aluminum foils, causing the rotation axis to tend to deflect, the reset spring structure absorbs these abnormal lateral forces through its own elastic deformation and uses elastic restoring force to force the suspension guide arm 41 and the central drive shaft 42 back to their initial absolutely concentric state, ensuring extremely high stability of the rotation winding axis. As the external arc plate 44 rotates steadily, the first ends of multiple copper and aluminum foils continuously ejected from the ends of the curved feed channels 35 overlap on the outer arc surface of the rotating external arc plate 44. The high-speed rotating external arc plate 44, relying on surface friction, rapidly rolls up these foils. Because multiple copper and aluminum foils simultaneously enter from different angles around the circumference, and while the external arc plate 44 rotates, the foils behind it are continuously pushed forward at a constant speed by the segmented input mechanism 3, the overlapping copper and aluminum foils are forced to interweave, overlap, and entwine in a spiral trajectory on the surface of the external arc plate 44. The layers of copper and aluminum foil eventually break away from their thin strip shape, physically weaving and coalescing into a single piece of material with a certain thickness. The internally multi-layered, interlocking composite columnar structure, under the continuous forced feeding of downstream materials, gradually detaches from the suspended area at the end of the external arc plate 44 and extends straight forward into the interior of the polymerization and flattening mechanism 5. The columnar structure first slides into the receiving end of the focusing guide tube 53. The focusing guide tube 53, with its unique funnel-shaped contraction section on its inner wall, applies a uniform radial converging pressure to the spiral columnar structure, which has just detached from the rotation center and is still in a loosely stacked state. This pressure forces the internally multi-layered spirally wound copper and aluminum foils to eliminate the loose gaps between them, making the spiral layers adhere more tightly to each other, completely locking the spiral structure and preventing it from naturally loosening and disintegrating. After being converging and tightened, the columnar structure... The material continues to advance along the internal channel, seamlessly connecting into the inner cavity of the flattening guide tube 54. The internal channel of the flattening guide tube 54 exhibits a gradual transition from a cylindrical shape to a flattened rectangle. When the solid columnar structure with a certain degree of plastic deformation is forcibly pushed within this channel, the gradually changing inner walls of the flattening guide tube 54 act like a mold, applying strong vertical compressive stress to the cylindrical cross-section. Under the dual action of this forced physical constraint and the rearward thrust, the layers of metal foil inside the columnar structure undergo intense plastic slippage and deformation. Its macroscopic shape is forcibly flattened from a three-dimensional cylinder, widening laterally, and finally reshaped at the output end of the flattening guide tube 54 into a prototype composite strip with an extremely dense internal structure and a flat strip-like appearance.As the initially flattened composite strip continues to move forward and crosses the operating area of ​​the positioning and cutting mechanism 6, the positioning and cutting mechanism 6 executes precise dynamic cutting intervention according to the preset length command of the control system. The drive wheel set of the belt conveyor 62 starts, driving the closed-loop belt to rotate at high speed. The linear displacement section of the belt firmly pulls the traction slide 63 fixed on it, causing the traction slide 63 to slide linearly in the same direction as the output direction of the composite strip. By controlling the operating speed of the belt conveyor 62, the linear sliding speed of the traction slide 63 is precisely tuned to be completely consistent with the output conveying speed of the initial composite strip, thus achieving a relatively static synchronous following state between the two. The instant this relatively static state is established, the cutting blade structure mounted on the traction slide 63 swiftly extends downwards and performs a shearing action. The sharp blade, with its powerful mechanical shearing force, vertically cuts into and instantly penetrates the multiple layers of densely stacked composite strip, cleanly and efficiently dividing the continuous strip into independent segments of the set length. After cutting, the cutting blade structure immediately rises, resets, and withdraws from the material area. The belt conveyor 62 then reverses its rotation, dragging the traction slide 63 back to its initial standby position, ready for the next fixed-length cutting cycle. The entire process does not hinder the continuous forward movement of the material. The flat, pre-formed composite strip, now cut into independent segments, continues to move forward under the residual force at the front end, officially... Upon entering the processing area of ​​the centralized pressing mechanism 7, the strip first passes through a semi-enclosed channel covered by a casing structure before reaching the final pressing and positioning station. Heating elements mounted at the top of the channel are energized and released high-intensity heat radiation onto the surface of the strip as it passes downwards. The high-temperature heat energy rapidly penetrates the surface of the strip and is conducted to each layer of copper and aluminum foil inside. During this heat treatment process, the lattice activity of the copper and aluminum metals is significantly increased, the overall material softens, and the yield strength of the metal decreases substantially. This greatly improves the multilayer plastic deformation capability of the metal and creates excellent thermodynamic conditions for subsequent interlayer bonding of dissimilar metals. The composite strip carrying sufficient heat energy is then guided into the relatively close pressing and positioning rollers 7. Within the narrow gap formed by rollers 3, the inclined roller frame 72 supports the pressing and positioning rollers 73 at a specific tilt angle. This tilted posture guides the strip to smoothly cut into the pressing and positioning deformation zone at the optimal bite angle. Two large and rigid pressing and positioning rollers 73 rotate synchronously in opposite directions under the drive of powerful mechanical force. When the heated and softened multi-layer composite strip is wound into the gap of the pressing and positioning rollers 73, the pressing and positioning rollers 73 apply an extremely large normal pressing force and tangential stretching force. Under this extreme combined action of high temperature and high pressure, the thickness of the composite strip is drastically compressed, resulting in a significant reduction in thickness and longitudinal extension, thus achieving interlocking between the multiple spirally interwoven copper and aluminum foils inside the strip.
