Description

Technical Field

[0001] This invention relates to the field of metal wire processing technology, specifically to a multi-segment heating, forming, and leveling equipment and method for phosphor bronze wire. Background Technology

[0002] Phosphor bronze alloys possess excellent electrical and thermal conductivity and elasticity, and copper ring-shaped components made from them are widely used in the field of electronic connectors. The processing of such copper ring parts typically involves processes such as heating and softening the wire, bending it into a circle, cutting it, and subsequent flatness correction.

[0003] In existing technologies, the aforementioned processes are often completed step-by-step on independent single machines. For example, preheating is done using a separate heating furnace, followed by forming on a bending machine, and finally leveling using a punch press or die. This discrete production model has many drawbacks: First, the material transfer between processes leads to a significant loss of heat, resulting in energy waste and making it difficult to ensure temperature consistency of the wire during bending, which can easily cause cracks or springback deformation due to localized overcooling. Second, the separate control of multiple machines leads to low overall production efficiency and requires a large number of operators. Furthermore, existing rolling forming methods mostly rely on hard extrusion using fixed dies, which has poor guidance for the front end of the wire, resulting in poor roundness of the formed copper ring. Moreover, the opening of the cut copper ring is prone to axial warping. Although leveling is performed, residual stress inside the material is often not eliminated, causing secondary springback in subsequent use, affecting the final product's assembly accuracy and electrical contact performance.

[0004] Therefore, how to achieve fully automated, high-precision, and highly consistent processing of phosphor bronze wire from feeding to finished copper rings is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of discrete processes, uneven temperature control, poor roundness of forming, and large residual stress after leveling in the existing technology, and to provide a highly integrated, high-precision, and stable multi-segment heating forming and leveling equipment and method for phosphor bronze wire. It aims to realize the continuous and automated production of phosphor bronze rings throughout the entire process, and significantly improve production efficiency and product quality consistency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A multi-segment heating and forming leveling device for phosphor bronze wire includes: The feeding mechanism transports the phosphor bronze wire along a straight path; Multiple heating mechanisms are distributed along the straight conveying path of the phosphor bronze wire to heat the phosphor bronze wire during the conveying process; A rotating mechanism is provided with a rotating body, which applies a force to the front end of the phosphor bronze wire that has been heated and fed at a constant speed, so as to drive the front end to rotate. A rolling mold is provided with a rolling groove, and the rolling groove and the outer peripheral surface of the rotating body form a forming cavity. A continuous force is applied to the front end of the phosphor bronze wire to force the front end to bend into a preset ring shape. The cutting mechanism is equipped with a cutting blade that can move longitudinally. The cutting blade is used to cut and separate the formed circular ring-shaped part from the phosphor bronze wire to obtain individual copper rings. The leveling mechanism is equipped with a leveling die and a leveling punch that moves relative to it. The leveling die receives and stores the cut and separated copper rings, and the leveling punch levels the copper rings in the leveling die by pressing down.

[0007] Furthermore, the rotating body is a cylindrical or disc-shaped component, and the front end of the phosphor bronze wire completes the rotation under the guidance of the circumferential surface of the rotating body.

[0008] Furthermore, the rolling mold is distributed in two sets along the rotating body. Each set of rolling molds includes: a fixed base; a mounting block, which is fixedly mounted on the fixed base; and a fixture, which is fixedly mounted on the mounting block. The fixture has a concave rolling groove at one end facing the rotating body.

[0009] Furthermore, the cutting mechanism also includes a first driving device, which is connected to the cutting blade and is used to drive the cutting blade to move longitudinally.

[0010] Furthermore, the leveling mechanism also includes a second driving device and a heating seat. The second driving device is driven and connected to the leveling punch to drive the leveling punch to move longitudinally. The leveling die is disposed inside the heating seat to heat the copper ring during the leveling process.

[0011] Furthermore, the leveling die has a receiving cavity whose shape matches the outer contour of the copper ring; the leveling die also has a blanking guide surface for guiding the copper ring down into the receiving cavity.

[0012] Furthermore, it also includes a blanking track for receiving copper rings cut and separated from the phosphor bronze wire and guiding them into a leveling die. Furthermore, the rotating body is a cylindrical or disc-shaped component, and the leading end of the phosphor bronze wire completes its rotation under the guidance of the circumferential surface of the rotating body.

[0013] Furthermore, the rolling mold includes two sets, each set of rolling molds including: a fixed base; a mounting block, fixedly mounted on the fixed base; and a fixture, fixedly mounted on the mounting block, one end of the fixture having the rolling groove matching the curvature of the copper ring.

[0014] Furthermore, the cutting mechanism also includes a first driving device, which is connected to the cutting blade and is used to drive the cutting blade to move longitudinally.

[0015] Furthermore, the leveling mechanism also includes a second driving device and a heating seat. The second driving device is driven and connected to the leveling punch to drive the leveling punch to move longitudinally. The heating seat is disposed outside the leveling die and is used to heat the copper ring during the leveling process.

[0016] Furthermore, the leveling die has a receiving cavity whose shape matches the outer contour of the copper ring; the leveling die also has a blanking guide surface for guiding the copper ring down into the receiving cavity.

[0017] Furthermore, it also includes a blanking track for receiving copper rings cut and separated from the phosphor bronze wire and guiding them into a leveling die.

[0018] This invention also provides a method for multi-segment heating and forming leveling of phosphor bronze wire, comprising the following steps: S1. The phosphor bronze wire is conveyed along a straight path by a feeding mechanism, and the phosphor bronze wire is heated by multiple heating mechanisms distributed along the conveying path. S2. The front end of the heated phosphor bronze wire is fed to the circumference of the rotating body at a constant speed. Driven by the friction of the rotating body and constrained by the rolling groove of the rolling mold, the front end of the phosphor bronze wire is continuously bent and deformed to form a copper ring. S3. The cutting blade of the drive cutting mechanism moves longitudinally to cut and separate the copper ring from the phosphor bronze wire; S4. The separated copper ring is received in the leveling die of the leveling mechanism, the leveling punch is driven to press down longitudinally, and the copper ring in the leveling die is heated by the heating seat set outside the leveling die to complete the leveling. S5: Repeat steps S1 to S3 to sequentially receive the multiple cut copper rings into the leveling die, and squeeze the multiple copper rings stacked in the leveling die together when performing step S4. Beneficial effects

[0019] This invention provides a multi-segment heating and forming leveling device for phosphor bronze wire, which has the following advantages compared with the prior art: 1. By integrating multi-stage heating, rotary rolling, cutting and separating, and leveling and shaping into the same production line, the repeated handling and clamping of materials between processes are eliminated, realizing continuous automated production from straight wire to finished copper rings, which significantly improves production efficiency.

[0020] 2. Multiple heating mechanisms distributed along the conveying path enable gradient heating or heat preservation of the wire, creating conditions for thermoplastic forming. The combination of the cylindrical rotating body and the rolling groove forces the front end of the wire to bend along the standard circumferential curvature in a high-temperature plastic state, ensuring that the formed copper ring has extremely high roundness.

[0021] 3. The rolling die adopts a separate structure of fixed base, mounting block and fixture. When the rolling groove wears due to long-term friction, only a small fixture needs to be replaced quickly, without disassembling large fixed parts, which greatly reduces downtime maintenance time and spare parts replacement costs.

[0022] 4. The leveling mechanism incorporates a heating seat outside the leveling die, providing a thermal field simultaneously during the pressing and leveling process. This softens the copper ring matrix, reducing the pressure energy required for leveling and, more importantly, eliminating the axial internal stress accumulated during bending. After cooling, the finished copper ring exhibits stable dimensions and extremely high flatness, effectively preventing secondary springback and warping during subsequent use.

[0023] 5. The leveling die is equipped with a blanking guide surface and a matching cavity, which can automatically correct the falling posture of the copper ring to ensure its accurate positioning. This enables continuous leveling operations without human intervention and reduces the damage to scrap products caused by misalignment. Attached Figure Description

[0025] 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.

[0026] like Figures 1 to 8 As shown, this embodiment provides a technical solution: a multi-segment heating and forming leveling device for phosphor bronze wire, including a feeding mechanism 1, a heating mechanism (not shown in the figure), a rotating mechanism (not shown in the figure), a rolling mold 3, a cutting mechanism 4, and a leveling mechanism 5.

[0027] The feeding mechanism 1 is located at the upstream end of the equipment and typically employs one or more pairs of clamping rollers driven by servo motors to clamp the phosphor bronze wire 7 and convey it along a straight path. Multiple heating mechanisms are axially distributed along the conveying path between the feeding mechanism 1 and the rolling die 3. In this embodiment, the heating mechanisms are preferably high-frequency induction heating coils or infrared heating tubes, capable of non-contact heating of the passing phosphor bronze wire 7. Because multiple heating mechanisms are distributed along the path, gradient heating can be achieved by adjusting the power of each segment, ensuring that the phosphor bronze wire reaches the optimal thermoplastic forming temperature before reaching the rolling station.

[0028] The rotating mechanism is located at the end of the feeding path, and its core component is a rotating body 2 driven by a power source. When the front end of the phosphor bronze wire 7, heated to a plastic state, is conveyed to the circumference of the rotating body 2, the rotating body 2 begins to rotate, using friction to drive the front end of the wire to follow it in a circular motion.

[0029] A rolling mold 3 is located on one side of the rotating body 2. A rolling groove 331 is formed on the end of the rolling mold 3 facing the rotating body 2. The rolling groove 331 and the outer circumferential surface of the rotating body 2 together form an approximately circular forming cavity. When the phosphor bronze wire 7 is conveyed forward at a constant speed, the force exerted by the rotating body 2 and the rolling groove 331 forces the wire to plastically bend against the surface of the rotating body 2, ultimately forming a complete or approximately complete circular ring shape.

[0030] The cutting mechanism 4 is located on one side adjacent to the rolling die 3. It is equipped with a cutting blade 41 that can move longitudinally. The cutting blade 41 is used to cut and separate the formed ring-shaped portion from the phosphor bronze wire to obtain individual copper rings 8. The leveling mechanism 5 is located on the lower side of the cutting mechanism 4. It is provided with a leveling die 51 and a leveling punch 52 that can move longitudinally. The leveling die 51 receives and stores the copper rings 8 after they have been cut and separated. The leveling punch 52 levels the copper rings 8 in the leveling die 51 by pressing down.

[0031] This technical solution achieves fully automated integration of the entire process of phosphor bronze wire production, from conveying, multi-stage heating, rotary winding, cutting and separating, to leveling and shaping. Compared with existing technologies, multiple heating mechanisms distributed along the path achieve gradient heating, avoiding local overheating; the cooperation between the rotating body 2 and the winding groove 331 allows the wire tip to bend into a ring directly in a high-temperature plastic state; the cutting blade 41 cuts the wire after shaping; and the cooperation between the leveling punch 52 and the leveling die 51 eliminates axial warping after bending. Integrating the originally discrete processes into a continuous production line significantly improves production efficiency and the consistency of copper ring forming.

[0032] In this embodiment, the rotating body 2 is a cylindrical or disc-shaped component. The front end of the phosphor bronze wire 7 completes its rotation under the guidance of the circumferential surface of the rotating body 2. As the front end of the phosphor bronze wire moves with the rotating body 2, it is simultaneously subjected to the action of the winding groove 331, which forces the wire to undergo plastic deformation along a standard circumferential curvature.

[0033] Two sets of coiling dies 3 are distributed along the rotating body 2. Each set of coiling dies 3 includes: a fixed base 31; a mounting block 32 fixedly mounted on the fixed base 31; and a fixture 33 fixedly mounted on the mounting block 32. The fixture 33 has a concave coiling groove 331 at its end facing the rotating body. The two sets of coiling dies limit and shape the rotating wire. The fixed base 31 provides a stable mounting reference. The separate design of the mounting block 32 and the fixture 33 allows for replacement of only the smaller fixture 33 when the coiling groove 331 wears out, without disassembling the entire machine, reducing maintenance difficulty and spare parts costs. Simultaneously, the coiling grooves 331 on the two sets of fixtures 33 together form a copper ring constraint cavity, ensuring that the wire is always confined within the preset copper ring trajectory during rotation and coiling.

[0034] The cutting mechanism 4 also includes a first driving device 42, which is connected to the cutting blade 41 and drives the cutting blade 41 to move longitudinally. The first driving device 42 drives the cutting blade 41 to perform longitudinal movement. This longitudinal punching method is similar to the shearing action of a precision mold, capable of applying instantaneous shearing force to the high-temperature phosphor bronze wire within an extremely short stroke. This ensures the closing accuracy of the opening of the copper ring 8 and the yield rate of subsequent leveling.

[0035] The leveling mechanism 5 also includes a second driving device 53 and a heating seat 54. The second driving device 53 is driven and connected to the leveling punch 52, and is used to drive the leveling punch 52 to move longitudinally. The heating seat 54 is located outside the leveling die 51, and a high-frequency induction heating coil or infrared heating tube is installed inside the heating seat 54 to heat the copper ring during the leveling process. The addition of the heating seat 54 outside the leveling die 51 allows the heating seat 54 to provide a thermal field simultaneously when the leveling punch 52 is pressed down by the second driving device 53. The heat softens the copper ring matrix, reduces the yield strength of the material, and allows the leveling punch 52 to press the copper ring flat with only a small amount of pressure, while eliminating the residual bending stress inside the copper ring. After cooling, the copper ring is dimensionally stable, has extremely high flatness, and no longer experiences springback or warping. The lower end of the leveling punch 52 has a tapered portion 521 integrally formed with it, and the lower end face of the leveling punch 52 has a flat surface 522. Since the copper ring 8 may be in a non-horizontal state when it falls into the leveling die 51, the tapered part 521 is designed to guide the copper ring 8 first. When the leveling punch 52 moves downward, the tapered part 521 is inserted into the inner ring of the copper ring 8, which guides the copper ring 8 first and then uses the leveling plane 522 to press down and level it, thereby further improving the leveling quality.

[0036] The leveling die 51 has a receiving cavity 511, the shape of which matches the outer contour of the copper ring 8. The leveling die 51 also has a blanking guide surface 512, used to guide the copper ring 8 down into the receiving cavity 511. The blanking guide surface 512 is inclined or flared, capable of receiving the copper ring falling from above and automatically sliding it into the receiving cavity 511 using gravitational potential energy. The precise match between the shape of the receiving cavity 511 and the outer contour of the copper ring 8 serves a positioning function. Even if the copper ring's falling posture is imperfect, under the combined constraint of the blanking guide surface 512 and the receiving cavity 511, the copper ring can automatically align itself, ensuring that the leveling punch 52 accurately acts on the annular surface of the copper ring with each press, avoiding misalignment and damage, and achieving automated leveling and positioning without human intervention.

[0037] To facilitate the transfer of the copper rings, this embodiment also includes a blanking track 6, which receives the copper rings 8 cut and separated from the phosphor bronze wire and guides them into the leveling die 51. The blanking track 6 serves as a bridge connecting the cutting station and the leveling station. This track is inclined and utilizes the weight of the copper rings to slide into the leveling die 51. In other embodiments, a steel wire can be used. One end of the steel wire extends to the cutting station to receive the separated copper rings, and the other end extends to the leveling die 51, also inclined, utilizing the weight of the copper rings to slide into the leveling die 51. It should be noted that the diameter of the steel wire is larger than the opening of the copper ring 8 to prevent accidental detachment during the process of guiding the copper rings into the leveling die.

[0038] This embodiment also provides a method for multi-segment heating and forming leveling of phosphor bronze wire, including the following steps: S1. The feeding mechanism 1 is activated, straightening the phosphor bronze wire 7 wound on the reel and conveying it forward at a constant speed. The wire passes through multiple heating mechanisms arranged along the path in sequence. The heating mechanisms perform gradient heating on the wire according to a preset temperature curve to ensure that the internal structure of the wire is uniformly softened and reaches a suitable plastic state for winding.

[0039] S2. The front end of the wire, heated to a preset temperature, abuts against the circumferential surface of the rotating body 2 of the rotating mechanism. The rotating body 2 rotates under the drive of a motor, using friction to carry the softened front end of the wire circumferentially. Simultaneously, the coiling mold 3, located around the periphery, constrains the wire through the coiling groove 331 on its fixture 33. The wire advances at a uniform speed, and its front end, guided by the combined pressure of the outer wall of the rotating body and the coiling groove 331, is forced to undergo continuous bending deformation until it coils around the rotating body once, forming a copper ring 8 that meets the preset diameter requirement.

[0040] S3. After the copper ring 8 is formed, the rotating mechanism stops rotating, and the feeding mechanism 1 pauses feeding. At this time, the first drive device 42 in the cutting mechanism 4 receives the instruction and drives the cutting blade 41 to press down rapidly along the longitudinal direction. The cutting edge of the cutting blade 41 acts on the connection between the rear end of the copper ring and the straight wire, and cuts it off with shearing force to obtain an independent open copper ring 8.

[0041] After the cutting blade 41 resets, the cut copper ring 8 falls freely due to the loss of support and enters the blanking track 6. The copper ring 8 is guided to slide towards the leveling station. After passing the trumpet-shaped blanking guide surface 512 on the top of the leveling die 51, the copper ring 8 smoothly slides into the receiving cavity 511 that matches the outer contour, achieving automatic alignment and positioning.

[0042] S4. After the copper ring 8 falls into the receiving cavity 511, the leveling process is initiated. First, the heating seat 54, which surrounds the leveling die 51, is energized and heats up to keep the copper ring 8 in the receiving cavity 511 warm, thereby eliminating the local stress generated during cooling during cutting and transfer, and further softening the material. Subsequently, the second drive device 43 drives the leveling punch 52 to move longitudinally downward, and the lower end face of the leveling punch 52 presses against the upper surface of the copper ring 8. Under the action of pressure and auxiliary thermal field, the axial warping deformation of the copper ring 8 is corrected and flattened.

[0043] S5. Repeat steps S1 to S3 to sequentially receive the multiple copper rings 8 obtained by cutting into the leveling die 51, and squeeze and level the multiple copper rings 8 stacked in the leveling die 51 together when performing step S4.

[0044] It should be noted that the feeding mechanism 1 is implemented using a conventional wire straightening and conveying device in the art. Specifically, it can consist of multiple sets of opposing pressure rollers and pressure straightening roller sets, driven by a speed-regulating motor. This mechanism is used to straighten the wound phosphor bronze wire and push it forward stably along a straight path, ensuring that the wire's travel speed is controllable and its posture is straight during the heating and forming process.

[0045] Regarding the heating mechanism (not shown in the figure), the multiple heating mechanisms arranged along the conveying path are commonly used in the prior art for online heating of metal wires, preferably employing high-frequency induction heating coils or infrared heating tubes. Each heating mechanism is spaced apart along the conveying direction, and its heating power is controlled independently or in conjunction with other mechanisms. As the phosphor bronze wire passes through, it undergoes non-contact, continuous gradient heating, gradually raising the wire temperature to the process temperature required for plastic deformation.

[0046] Regarding the rotating mechanism (not shown in the figure), this mechanism includes a rotating body 2 driven by a motor. The rotating body 2 is a cylinder or disk, and its circumferential surface serves as a template for bending the wire, thereby performing a winding action. Regarding the first drive device 42 and the second drive device 53, both drive devices employ conventional methods in the art, such as a motor combined with a linear module or cam mechanism, to achieve reciprocating linear motion.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
