Description

Technical Field

[0001] This invention relates to the field of metal wire processing technology, and in particular to an automated metal wire flattening device. Background Technology

[0002] Regarding the drawbacks of round wires, firstly, round wires involve point / line contact, resulting in a very small contact area. Flattening allows for a larger contact area, reducing contact resistance and thermal resistance, and improving connection reliability. This is because the flat surfaces adhere to the wires, unlike round wires which are only attached by a single line. Secondly, round cross-sections have extremely high porosity in rectangular slots / gaps (theoretically, the maximum filling rate is only ~78%). Flattening significantly increases the slot fill rate / stack rate, allowing the flat wires to be arranged closely. This means that more effective cross-sectional area can be accommodated in the same space. Therefore, flattening is necessary for the efficient use of round wires in specific applications.

[0003] A search revealed a Chinese patent publication number CN109746350B, which discloses a high-precision, high-speed flattening machine for manufacturing spinning steel wire loops. It consists of a round wire feeding mechanism, a straightening mechanism, a flattening mechanism, a pressing and forming mechanism, and a take-up mechanism. The round wire feeding mechanism comprises a rotating base plate, a rotating shaft, a self-stabilizing brake, and a detachable support frame. The straightening mechanism consists of a nylon straightener, a feeding tensioner, and a straightening wheel. The feeding tensioner has a fixed wheel and a sliding wheel, with grooves on the wheels. The flattening mechanism includes upper and lower rollers, a wire guide, and a flattening tensioner. The upper and lower rollers in the pressing and forming mechanism both have forming grooves, through which the flattened wire is formed and flattened.

[0004] The above-mentioned patent has the following shortcomings: it uses single-pass large deformation flattening. For high-hardness metal wires (such as titanium alloy wires), single-pass large deformation flattening is very likely to cause wire breakage or surface micro-cracks. If multiple passes of linearly arranged pressure rollers are set on its basis, the equipment length will be too long, and the wire is prone to torsional stress during repeated turning.

[0005] Therefore, this invention proposes an automated flattening device for metal wires. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated wire flattening device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An automated flattening device for metal wire includes a flattening section, which comprises an upper shell and a lower shell fixedly fitted together. A main horizontal roll assembly, a vertical roll assembly, and a secondary horizontal roll assembly are respectively arranged inside the upper and lower shells. A set of guide wheel assemblies are arranged on both sides of the vertical roll assembly. The metal wire enters from one end of the upper and lower shells, undergoes initial rolling through the main horizontal roll assembly, is guided by one set of guide wheel assemblies, enters the vertical roll assembly for side pressing, is guided by another set of guide wheel assemblies, enters the secondary horizontal roll assembly for final rolling, and then exits from the other side of the lower shell. The metal wire exhibits multiple "S"-shaped bends inside the upper and lower shells. The main horizontal roll assembly and the secondary horizontal roll assembly have the same structure, each consisting of two horizontal rolls arranged vertically and cooperating with each other. The vertical roll assembly consists of multiple sets of vertical rolls, with each set of vertical rolls working in pairs.

[0008] Preferably, one of the horizontal rollers is rotatably connected to the inner wall of the upper housing via a roller shaft; The other horizontal roll is rotatably connected to two sides by a roller shaft, and the slider is longitudinally slidably connected to the side wall of the lower housing. The lower housing is provided with a set of adjustment components on the outer wall at both ends of the horizontal roll.

[0009] Furthermore: the adjustment assembly includes a wedge and a threaded rod. The wedge is slidably connected to the side wall of the lower housing via a guide rod. The outer wall of the threaded rod is threadedly connected to the side wall of the lower housing, and the end of the threaded rod is rotatably connected to the side wall of the wedge. The wedge and the slider are engaged by an inclined surface.

[0010] Based on the aforementioned scheme: the vertical roll assembly also includes a stand fixed to the inner wall of the upper housing. Both ends of the vertical roll are rotatably connected to a slider 1 via a roller shaft 2. The slider 1 is slidably connected to the inner wall of the stand. The two sliders 1 in the same group are provided with elastic bodies on their sides. The two sliders 1 in the same group are subject to the elastic force of the elastic bodies and have a tendency to move closer to each other.

[0011] A preferred embodiment of the aforementioned scheme is as follows: the upper housing is provided with multiple pump heads on the top lower surface of the main horizontal roll assembly, which correspond to the number and position of the metal wires being processed synchronously. The drive shafts of the multiple pump heads are connected by a coupling transmission. The output port of the pump head is connected to a dripper, and the input port of the pump head is connected to a lubricating oil storage container.

[0012] As a further embodiment of the present invention: guide sleeves are provided on the inlet and outlet sides of the upper and lower housings, and an oil absorbing block for wiping and absorbing oil on the surface of the metal wire is provided inside the guide sleeve on the outlet side, and an oil box is detachably provided at the bottom of the lower housing.

[0013] It also includes a winding section for winding the wire and an integrated tension and speed sensing section for sensing the winding speed and tension of the wire.

[0014] As a preferred embodiment of the present invention: the winding section includes two opposing uprights and multiple drums that match the number of metal wires processed simultaneously. The inner sides of the multiple drums are connected to the same shaft. Each upright is provided with a set of half-shaft seats at its top. The two ends of the shaft are rotatably connected to the interior of the two sets of half-shaft seats respectively. One of the support frames has a motor fixed to its side wall, and the output shaft of the motor is fixed with a bushing, which is engaged with the end of the reel. The bushing and the reel achieve rotary transmission while allowing axial relative movement through the gap fit between the key-shaped protrusion and the key-shaped groove.

[0015] Meanwhile, the tension and speed integrated sensing unit includes two opposing uprights and sensing rollers disposed inside the two uprights. Both ends of the sensing rollers are rotatably connected to a set of sliders via roller shafts. The sliders are slidably connected to the inner wall of the uprights, and a spring is fastened to the top outer wall of the sliders. The other end of the spring is fitted with a pressure sensor, and the outer shell of the pressure sensor is fixed to the inner wall of the uprights.

[0016] As a preferred embodiment of the present invention: the rolled metal wire passes through the top of the induction roller, and the winding height of the winding section is greater than the height of the induction roller.

[0017] The beneficial effects of this invention are as follows: 1. This invention employs a series of processes—primary rolling, side rolling, and finishing rolling—for the overall flattening process. Combined with a guide wheel assembly to guide the metal wire through multiple "S" paths, this design disperses deformation heat and work hardening rate, enabling continuous flattening of difficult-to-deform metals such as titanium and magnesium without brittle fracture. Furthermore, the S-shaped layout significantly shortens the longitudinal length of the equipment, and the wire remains under controlled tension, minimizing vibration. Simultaneously, the S-shaped metal wire undergoes multiple micro-deformations during transport, reliably releasing internal stress and preventing warping and breakage.

[0018] 2. In this invention, one horizontal roller is fixedly mounted on the upper housing, and the other horizontal roller is adjustablely mounted on the side wall of the lower housing via an adjustment component. This allows the spacing between the two horizontal rollers to be adjusted according to the position of the adjustment component on the lower housing, thereby controlling the rolling dimensions of each process and increasing the precision and quality of the metal wire rolling and flattening.

[0019] 3. In this invention, the connecting shaft is driven by rotation, which drives multiple pump heads to start, drawing out the lubricating oil stored in the lubricating oil and spraying it onto the surface of the metal wire through the drip nozzle. On the one hand, it can lubricate the metal wire to prevent it from being strained, and on the other hand, the lubricating oil can also absorb the heat generated, reduce the temperature rise, and prevent breakage.

[0020] 4. In this invention, by setting up a tension and speed integrated sensing unit and a winding unit that cooperate with each other, and utilizing the sensing roller and pressure sensor in the tension and speed integrated sensing unit, on the one hand, the tension can be dynamically sensed, thereby dynamically controlling the tension in conjunction with the winding speed of the winding unit; on the other hand, the sensing roller can move up and down to buffer when there are fluctuations in the winding speed, thereby increasing safety.

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1: An automated wire flattening device, such as Figures 1-10 As shown, the device includes a flattening section 1, which comprises an upper shell 4 and a lower shell 6 that are fixedly fitted together. The upper shell 4 and the lower shell 6 are respectively provided with a main horizontal roll assembly 7, a vertical roll assembly 8, and a secondary horizontal roll assembly 5. A set of guide wheel assemblies 9 are respectively provided on both sides of the vertical roll assembly 8. The metal wire enters from one end of the upper shell 4 and the lower shell 6, and then passes through the main horizontal roll assembly 7 for initial rolling, is guided by one of the guide wheel assemblies 9 and enters the vertical roll assembly 8 for side pressing, is guided by another set of guide wheel assemblies 9 and enters the secondary horizontal roll assembly 5 for finishing rolling, and then passes out from the other side of the lower shell 6. The metal wire has multiple "S"-shaped bends inside the upper shell 4 and the lower shell 6.

[0026] The main horizontal roll assembly 7 and the secondary horizontal roll assembly 5 have the same structure. They are both composed of two horizontal rolls 10 arranged vertically and cooperating with each other. One of the horizontal rolls 10 has a trapezoidal convex ring 12 on its outer surface, and the other horizontal roll 10 that cooperates with it has a trapezoidal groove 13 on its surface. The cooperation between the trapezoidal convex ring 12 and the trapezoidal groove 13 can guide and position the metal wire relative to its axial position and prevent it from shifting.

[0027] The vertical roll assembly 8 consists of multiple sets of vertical rolls 15, which work in pairs, and the surface of each vertical roll 15 is provided with a groove 16. The groove 16 on the surface of the vertical roll 15 is also provided to guide and position the metal wire and prevent it from deviating.

[0028] In use, the metal wire enters from one side of the upper housing 4 and the lower housing 6. It first enters the two horizontal rollers 10 in the main horizontal roller assembly 7 for preliminary rolling, so that the cross-section of the metal wire is elliptical. Then, the elliptical metal wire is guided by a set of guide wheel assemblies 9 and enters the vertical roller assembly 8. It is then laterally squeezed by the vertical rollers 15 in the vertical roller assembly 8. After being laterally squeezed, the metal wire enters the secondary horizontal roller assembly 5 and is finally shaped by the two horizontal rollers 10 in the secondary horizontal roller assembly 5.

[0029] This device employs a series of processes for overall flattening, including initial rolling, side rolling, and finishing rolling. Combined with guide wheel assembly 9, it guides the metal wires through multiple "S" paths. This disperses deformation heat and work hardening rate, enabling continuous flattening of difficult-to-deform metals such as titanium and magnesium without brittle fracture. Furthermore, the S-shaped layout significantly shortens the longitudinal length of the equipment, and the wire remains under controlled tension, minimizing vibration. Simultaneously, the S-shaped metal wire undergoes multiple micro-deformations during transport, reliably releasing internal stress and preventing warping and breakage.

[0030] To solve the problem of extrusion control; such as Figure 6 As shown, one of the horizontal rollers 10 is rotatably connected to the inner wall of the upper housing 4 via a roller shaft 11.

[0031] The other horizontal roller 10 has two sides rotatably connected to slider 23 via roller shaft 11. Slider 23 is longitudinally slidably connected to the side wall of the lower housing 6, and the lower housing 6 is provided with a set of adjustment components on the outer wall at both ends of the horizontal roller 10.

[0032] The adjustment assembly includes a wedge 20 and a threaded rod 22. The wedge 20 is slidably connected to the side wall of the lower housing 6 via a guide rod 21. The outer wall of the threaded rod 22 is threadedly connected to the side wall of the lower housing 6, and the end of the threaded rod 22 is rotatably connected to the side wall of the wedge 20. The wedge 20 and the slider 23 are engaged by an inclined surface 24.

[0033] For metal wires with different hardness and diameter, the dimensional requirements for primary rolling and finishing rolling are different. Based on this, when adjustment is required, the threaded rod 22 can be rotated. The threaded rod 22 moves axially through its threaded connection with the lower housing 6, thereby driving the wedge block 20 to move. Then, the inclined plane 24 drives the slider 23 to move up and down, thereby changing the distance between the two horizontal rollers 10 and achieving the purpose of controlling the rolling dimensions of each process.

[0034] In this device, one horizontal roller 10 is fixedly mounted on the upper housing 4, and the other horizontal roller 10 is adjustablely mounted on the side wall of the lower housing 6 via an adjustment component. This allows the spacing between the two horizontal rollers 10 to be adjusted according to the position of the lower housing 6 by the adjustment component, thereby controlling the rolling dimensions of each process and increasing the precision and quality of the metal wire rolling and flattening.

[0035] like Figure 4 As shown, the vertical roll assembly 8 also includes a stand 14 fixed to the inner wall of the upper housing 4. Both ends of the vertical roll 15 are rotatably connected to sliders 19 via roller shafts 17. Slider 19 is slidably connected to the inner wall of the stand 14. Both sides of the two sliders 19 in the same group are provided with elastic bodies 18. The two sliders 19 in the same group are subject to the elastic force of the elastic bodies 18 and have a tendency to move closer to each other.

[0036] The elastic body 18 can apply an elastic force to the two sliders 19 in the same group, so that the two vertical rollers 15 are elastically attached to each other. When the elliptical cross-section metal wire enters between the two vertical rollers 15, it will deform due to the elastic force.

[0037] In this embodiment, it should also include a corresponding drive assembly, which is mainly responsible for driving the horizontal rolls 10 in the secondary horizontal roll assembly 5 and the main horizontal roll assembly 7 to rotate, and the vertical rolls 15 in the vertical roll assembly 8 to rotate. It should also ensure that the horizontal rolls 10 and the vertical rolls 15 have the same speed and direction of movement on the side that contacts the metal wire. This can be achieved by the cooperation of a chain drive assembly, belt drive assembly or gear drive assembly with a tensioning device. Since these are all existing technologies and are conventional knowledge and means for those skilled in the art, this embodiment has not made any creative effort on them, so they will not be described in detail.

[0038] To further address the issues of flattening effect and precision, such as Figure 7 As shown, the upper housing 4 is provided with multiple pump heads 25 on the top lower surface of the main horizontal roll assembly 7, which correspond to the number and position of the metal wires processed synchronously. The drive shafts of the multiple pump heads 25 are connected to the transmission through the coupling shaft 26. The output port of the pump head 25 is connected to the drip head 27, and the input port of the pump head 25 is connected to the lubricating oil storage container.

[0039] Furthermore, both the upper housing 4 and the lower housing 6 are provided with guide sleeves 29 on the inlet and outlet sides. Inside the guide sleeve 29 on the outlet side, there is a wiping and oil-absorbing block 28 for wiping and absorbing oil on the surface of the metal wire. The bottom of the lower housing 6 is detachably provided with an oil box.

[0040] In this embodiment, the driving method of the connecting shaft 26 is not limited. It can be driven synchronously with the rolling mill or driven independently. All of these are existing technologies, and this embodiment has not made any creative effort in them, so they will not be described in detail.

[0041] During actual rolling, on the one hand, the speed and pressure differences between various rolling components may cause significant friction between the metal wire and the rolling components. On the other hand, the metal wire will also generate heat during the rolling deformation process. Since the specific heat of metal is relatively small, the heat generation and temperature rise pose a risk of breakage. Based on this, when the device is in use, the connecting shaft 26 is driven by rotation, which drives multiple pump heads 25 to start, drawing out the lubricating oil stored in the lubricating oil and spraying it onto the surface of the metal wire through the drip head 27. This can lubricate the metal wire and prevent it from being pulled. On the other hand, the lubricating oil can also absorb the heat generated, reduce the temperature rise, and prevent breakage. In addition, when the metal wire is output through the guide sleeve 29 on the outlet side after three rolling processes, the lubricating oil on its surface is wiped and absorbed by the wiping oil suction block 28 and then sent out. At the same time, the lubricating oil absorbed into the wiping oil suction block 28 drips down to the bottom of the lower housing 6 under gravity and then flows into the oil box.

[0042] In this embodiment, the metal wire enters from one side of the upper housing 4 and the lower housing 6. It first enters the two horizontal rollers 10 in the main horizontal roller assembly 7 for preliminary rolling, resulting in an elliptical cross-section. Simultaneously, the connecting shaft 26 is driven to rotate, activating multiple pump heads 25 to extract stored lubricating oil and spray it onto the surface of the metal wire through drippers 27. The elliptical metal wire is then guided by a set of guide wheel assemblies 9 and enters the vertical roller assembly 8. The elastic body 18 applies an elastic force to the two sliders 19 within the same assembly, causing the two vertical rollers 15 to elastically adhere to each other. When the elliptical cross-section metal wire enters between the two vertical rollers 15, it deforms due to the elastic force. After lateral compression, the metal wire enters the secondary horizontal roller assembly 5, where it is subjected to... The two horizontal rollers 10 in the middle are used to extrude and finally form the metal wire. When the formed metal wire is output through the guide sleeve 29 on the exit side, the lubricating oil on its surface is wiped and absorbed by the wiping oil absorption block 28 and then sent out. At the same time, the lubricating oil absorbed into the wiping oil absorption block 28 is dripped to the bottom of the lower housing 6 by gravity and then flows into the oil box. In addition, for metal wires with different hardness and different diameters, the dimensional requirements for primary rolling and finishing rolling are different. Based on this, when it is necessary to adjust the rolling dimensions of the secondary horizontal roller assembly 5 and the main horizontal roller assembly 7, the threaded rod 22 can be rotated. The threaded rod 22 moves axially through the threaded connection with the lower housing 6, thereby driving the wedge block 20 to move. Then, the inclined plane 24 drives the slider 23 to move up and down, thereby changing the distance between the two horizontal rollers 10 and achieving the purpose of controlling the rolling dimensions of each process.

[0043] Example 2: An automated wire flattening device, such as... Figure 1 , Figures 8-10 As shown, this embodiment makes the following improvements based on embodiment 1: it further includes a winding section 3 for winding the metal wire and a tension-speed integrated sensing section 2 for sensing the winding speed and tension of the metal wire; the winding section 3 can wind the rolled and flattened metal wire, and at the same time, during the winding process, the tension-speed integrated sensing section 2 senses the winding speed and tension of the metal wire, and then controls the winding speed according to the actual sensed tension and speed and the preset tension and speed.

[0044] The winding section 3 includes two opposing uprights 36 and multiple spools 41 that match the number of wires processed simultaneously. The inner sides of the multiple spools 41 are connected to the same shaft 40. Each upright 36 has a set of half-shaft seats 39 at its top. The two ends of the shaft 40 are rotatably connected to the inside of the two sets of half-shaft seats 39 respectively.

[0045] One of the uprights 36 has a motor 37 fixed to its side wall. The output shaft of the motor 37 is fixed with a bushing 38, and the bushing 38 is engaged with the end of the reel 40.

[0046] The bushing 38 and the roller 40 achieve rotary transmission while allowing axial relative movement through the clearance fit between the key-shaped protrusion 42 and the key-shaped groove 43.

[0047] When using this device, during installation, first install multiple drums 41 onto the outer wall of the shaft 40, then disassemble the upper part of the half-shaft seat 39, insert one end of the shaft 40 into the inside of the bushing 38, and then place both ends into the bottom half-shaft seat 39. After that, install the disassembled half-shaft seat 39. After installation, when the motor 37 starts, it can drive the bushing 38 to rotate, thereby driving the shaft 40 and the drums 41 to rotate.

[0048] The tension and speed integrated sensing unit 2 includes two opposing uprights 33 and sensing rollers 30 disposed inside the two uprights 33. Both ends of the sensing rollers 30 are rotatably connected to a set of sliders 34 via roller shafts 35. The sliders 34 are slidably connected to the inner wall of the uprights 33, and a spring 32 is fastened to the top outer wall of the sliders 34. The other end of the spring 32 is fitted with a pressure sensor 31, and the outer shell of the pressure sensor 31 is fixed to the inner wall of the uprights 33.

[0049] Furthermore, the rolled metal wire passes through the top of the induction roller 30, and the winding height of the winding section 3 is greater than the height of the induction roller 30.

[0050] During the actual rolling and winding process, the wire outlets of the upper housing 4 and lower housing 6, the induction roller 30, and the winding height of the winding section 3 cause the metal wire between the flattening section 1 and the winding section 3 to form a "V" shape. Due to the tension, the metal wire exerts an upward force on the induction roller 30. This force overcomes the weight of the induction roller 30, driving it to move upward a portion. The slider 34 rises, the spring 32 is compressed, and the pressure sensor 31 senses the elastic force of the spring 32, thereby sensing the position of the slider 34 and thus the height of the induction roller 30. Combined with the weight of the induction roller 30, the slider 34, and the roller shaft 35, the metal wire is pushed by the force of the induction roller 30. Combined with the determined positions of the wire outlets of the upper housing 4 and lower housing 6, the determined winding height of the winding section 3, and the calculated height of the induction roller 30, the "V" angle can be calculated. Then, based on the composition and decomposition of the forces and the calculation of the tension of the metal wire, the winding speed is adjusted according to the calculated tension.

[0051] This device, by setting up a tension and speed integrated sensing unit 2 and a winding unit 3 that cooperate with each other, utilizes the sensing roller 30 and pressure sensor 31 in the tension and speed integrated sensing unit 2. On the one hand, it can dynamically sense the tension, thereby dynamically controlling the tension in conjunction with the winding speed of the winding unit 3. On the other hand, the sensing roller 30 can move up and down, which can also buffer when the winding speed fluctuates, increasing safety.

[0052] In this embodiment, during installation, multiple rolls 41 are first installed on the outer wall of the roll 40. Then, the upper half of the half-shaft seat 39 is disassembled, and one end of the roll 40 is inserted into the bushing 38. Both ends are then placed into the bottom half-shaft seat 39. The disassembled half-shaft seat 39 is then reinstalled. After installation, when the motor 37 starts, it drives the bushing 38 to rotate, thereby driving the roll 40 and rolls 41 to rotate. Furthermore, during the actual rolling and winding process, the winding height of the upper housing 4 and lower housing 6 outlets, the induction roller 30, and the winding section 3 causes the metal wire between the flattening section 1 and the winding section 3 to form a "V" shape. Due to the tension, the metal wire applies a force to the induction roller 30. An upward force overcomes the weight of the sensing roller 30, driving it to move upward a portion of its length. The slider 34 rises, compressing the spring 32. The pressure sensor 31 senses the elastic force of the spring 32, thereby sensing the position of the slider 34 and thus the height of the sensing roller 30. Combined with the weight of the sensing roller 30, slider 34, and roller shaft 35, the metal wire is pushed against the force of the sensing roller 30. Combined with the determined positions of the wire outlets of the upper housing 4 and lower housing 6, the determined winding height of the winding section 3, and the calculated height of the sensing roller 30, the "V" angle can be calculated. Then, based on the composition and decomposition of forces and the calculation of the tension of the metal wire, the winding speed is adjusted according to the calculated tension.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
