Description

Technical Field

[0001] The invention belongs to the technical field of corrugated wire processing equipment, and in particular relates to a processing equipment for buckling and shaping corrugated wire and a processing method thereof. Background Art

[0002] In the existing processing equipment, the corrugated wire is mainly formed by processing the straight wire, that is, after the straight wire is processed by the processing equipment, the straight wire is converted into the corrugated wire, and the equipment for processing the straight wire into the corrugated wire is the processing equipment for corrugated wire bending and shaping.

[0003] For example, the utility model patent with authorization announcement number CN2675386Y covers a corrugated wire tooth rolling machine used to press straight brush wire into a corrugated shape during the production process. The machine comprises a corrugating gear, a transmission gear, a roller, a pulley, a bracket, and an electric motor. The bracket houses the active and driven corrugating hobbing units. A frequency converter for adjusting the motor speed is located on one side of the bracket, and the motor is mounted below. The hobbing is speed-adjustable with an arc, meaning the tooth peaks are machined into an arc.

[0017] A method for processing corrugated wire by buckling and shaping, comprising the following steps:

[0018] S1: starting the heating assembly to heat the buckling upper roller and the buckling lower roller;

[0019] S2: After the upper buckling roller and the lower buckling roller both reach a preset temperature, controlling the upper buckling roller and the lower buckling roller to rotate;

When the upper buckling roller and the lower buckling roller reach the preset temperature, the upper buckling roller and the lower buckling roller rotate to jointly achieve the buckling and shaping treatment of the straight wire. Since the upper buckling roller and the lower buckling roller jointly use mechanical pressure to buckle and shape the straight wire, the corrugated wire after buckling and shaping is also subjected to heat treatment, so that the corrugated wire can be locally softened during the compression process, thereby making it easier to undergo plastic deformation. This heat setting treatment can effectively reduce the structural stress of the corrugated wire during the forming process, so that the molecular chains of the corrugated wire can be rearranged more evenly under the dual effects of heat and pressure, thereby reducing problems such as wire breakage, dimensional deviation and surface quality defects caused by stress concentration, improving the dimensional accuracy and surface quality of the corrugated wire, and solving the problem that the existing corrugated wires are all shaped by mechanical pressure. However, this shaping method will cause the structural stress distribution of the corrugated wire during the forming process to be uneven, which will directly affect the dimensional deviation and surface quality defects of the corrugated wire after the finished product, making it difficult to meet the market's demand for high-precision and high-quality production of corrugated wires.

DETAILED DESCRIPTION

[0033] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0034] See also Figure 1-Figure 7The present embodiment provides a processing device for corrugated wire buckling and shaping, comprising a processing frame 1, an upper buckling roller 2, a lower buckling roller 3 and a heating assembly 4. The processing frame 1 is provided with a buckling space, the upper buckling roller 2 and the lower buckling roller 3 are rotatably arranged at the top and bottom of the buckling space respectively, the axial direction of the upper buckling roller 2 and the axial direction of the lower buckling roller 3 are parallel to each other, the heating assembly 4 is used to control the temperature of the upper buckling roller 2 and the lower buckling roller 3, and the distance between the upper buckling roller 2 and the lower buckling roller 3 is smaller than the diameter of the straight wire; A heating component 4 is provided, which is used to control the temperature of the upper buckling roller 2 and the lower buckling roller 3. When the upper buckling roller 2 and the lower buckling roller 3 reach the preset temperature, the upper buckling roller 2 and the lower buckling roller 3 rotate to jointly realize the buckling and shaping treatment of the straight wire. Since the upper buckling roller 2 and the lower buckling roller 3 jointly use mechanical pressure to buckle and shape the straight wire, the corrugated wire after buckling and shaping is also subjected to heat treatment, so that the corrugated wire can be locally softened during the compression process, thereby making it easier to undergo plastic deformation. This heat setting treatment can effectively reduce the structural stress of the corrugated wire during the forming process, so that the molecular chains of the corrugated wire can be rearranged more evenly under the dual effects of heat and pressure, thereby reducing problems such as wire breakage, dimensional deviation and surface quality defects caused by stress concentration, improving the dimensional accuracy and surface quality of the corrugated wire, and solving the problem that the existing corrugated wires are all shaped by mechanical pressure. However, this shaping method will cause the structural stress distribution of the corrugated wire during the forming process to be uneven, which will directly affect the dimensional deviation and surface quality defects of the corrugated wire after the finished product, making it difficult to meet the market's demand for high-precision and high-quality production of corrugated wires.

[0035] Specifically, the upper buckling roller 2 includes an upper buckling shaft 201 and several pressing ends 202. The upper buckling shaft 201 can be rotatably arranged in the buckling space, and the several pressing ends 202 can be arranged at equal angles along the axial direction of the upper buckling shaft 201. The axial direction of the pressing end 202 is parallel to the axial direction of the upper buckling shaft 201. Through such an arrangement, when the upper buckling shaft 201 starts to rotate, it will drive the several pressing ends 202 to rotate, thereby realizing the mechanical pressing treatment of the straight wire by the pressing end 202, and completing the buckling and shaping of the straight wire.

[0036] Specifically, in this solution, the upper bending shaft 201 and the pressing end 202 jointly form a temperature control space, and the heating component 4 includes a heat conduction tank 401 filled with heat conduction oil, a heat conduction pump 402, an oil conduction pipe 403, an oil drain pipe 404 and a first one-way valve 405. The heat conduction tank 401 is arranged in the processing frame 1, the heat conduction pump 402 is connected to the heat conduction tank 401, and the two ends of the oil conduction pipe 403 are respectively connected to one end of the temperature control space and the heat conduction pump 402, and the two ends of the oil drain pipe 404 are respectively connected to the other end of the temperature control space and the heat conduction tank 401. The first one-way valve 405 is sealed and arranged at the connection between the heat conduction tank 401 and the oil drain pipe 404; With this arrangement, when the heat pump 402 starts operating, the heat transfer oil in the heat transfer tank 401 will flow into one end of the temperature-controlled space through the oil pipe 403. Then, the heat transfer oil in the temperature-controlled space will flow back into the heat transfer tank 401 from the other end of the temperature-controlled space. As the heat transfer oil flows in the temperature-controlled space, the heat in the heat transfer oil will continuously transfer from the heat transfer oil to the buckling upper roller 2, thereby increasing the temperature of the buckling upper roller 2. The function of the first one-way valve 405 is to ensure that the flow direction of the heat transfer oil does not reverse, ensuring that the heat transfer oil in the temperature-controlled space can flow normally back into the heat transfer tank 401. It is also worth noting that two first one-way valves 405 are provided in this solution, and the other first one-way valve 405 is sealed at the connection between the heat pump 402 and the oil pipe 403.

[0037] In addition, it should be noted that the heating component 4 of this solution also includes a heating device, which is arranged in the heat conduction tank 401 and is used to heat the heat conduction oil in the heat conduction tank 401 so that the heat conduction oil in the heat conduction tank 401 is always maintained at a preset temperature.

[0038] Furthermore, the temperature control space of this solution is arranged in a spiral shape around the central axis of the buckling upper shaft 201 and inside the buckling upper roller 2. The cross-sectional shape of the temperature control space is similar to the cross-sectional shape of the outer diameter of the buckling upper roller 2, and from a cross-sectional view, the diameter of the spiral winding of the temperature control space is slightly smaller than the outer diameter of the buckling upper shaft 201. With this arrangement, when the heat transfer oil flows in the temperature control space, the heat of the heat transfer oil will first be transferred to the outer surface of the buckling upper roller 2, so that the surface temperature of the buckling upper roller 2 can be increased in a relatively short period of time. In addition, the spiral winding temperature control space makes the flow path of the heat transfer oil inside the buckling upper roller 2 longer and more evenly distributed. This can effectively avoid excessive or insufficient heat concentration in a local area, thereby ensuring the temperature uniformity of the surface of the buckling upper roller 2. During the corrugated wire bending and shaping process, this uniform heat distribution can make the corrugated wire more evenly heated when it comes into contact with the bending upper roller 2, thereby making the reorganization of the material molecular chains under the action of heat more orderly, reducing the stress concentration caused by uneven temperature, and improving the shaping quality of the corrugated wire. At the same time, the spirally wrapped temperature control space design helps to enhance the heat exchange efficiency between the thermal oil and the inner wall of the bending upper roller 2. Since the thermal oil can more fully exchange heat with the inner wall of the bending upper roller 2 when flowing in the spiral pipe, the temperature of the bending upper roller 2 can respond more quickly to the adjustment of the heating component 4, thereby achieving more precise temperature control. During the processing process, this precise temperature control can ensure that the corrugated wire is always bent and shaped in a suitable temperature environment, avoiding the impact of excessive temperature fluctuations on the dimensional accuracy and surface quality of the corrugated wire.

[0039] According to the above embodiment, this solution mainly realizes the conversion of straight wire into corrugated wire by mechanically pressing the straight wire through the pressing end 202. In addition, in addition to mechanically pressing the straight wire, the end surface of the pressing end 202 also performs a transmission process on the straight wire to realize the movement of the corrugated wire. Therefore, in the actual working process, after the pressing end 202 presses the straight wire, as the pressing end 202 rotates, one end surface of the pressing end 202 will fit and push the end surface of the pressing depression of the corrugated wire, thereby realizing the movement of the corrugated wire. Therefore, in fact, the heat transferred to the corrugated wire by the end surface of the pressing end 202 close to the sliding push of the corrugated wire will be greater than the heat transferred to the corrugated wire by the end surface of the pressing end 202 far away from the sliding push of the corrugated wire. In order to ensure that the temperature on the end surface of the pressing end 202 close to the end surface that pushes the corrugated wire to slide can always reach the preset temperature when pressing the straight wire, in this solution, the distance between the end surface of the pressing end 202 close to the end surface that pushes the corrugated wire to slide and the temperature control space is smaller than the distance between the end surface of the pressing end 202 away from the end surface that pushes the corrugated wire to slide and the temperature control space; through such a setting, the heat of the heat transfer oil in the temperature control space can be accelerated to the end surface of the pressing end 202 close to the end surface that pushes the corrugated wire to slide, thereby ensuring that the temperature on the end surface of the pressing end 202 close to the end surface that pushes the corrugated wire to slide can always reach the preset temperature when pressing the straight wire. At the same time, it is also worth mentioning that such a setting has another advantage: after the pressing end 202 completes its pressing process on the corrugated wire, the end face of the pressing end 202 close to the corrugated wire that pushes the corrugated wire to slide will be in contact with the end face of the pressing depression of the corrugated wire for a short period of time. In this case, during the process of the pressing end 202 pressing the corrugated wire, due to the temperature of the pressing end 202, the deformation of the pressing depression of the corrugated wire close to the end where the pressing end 202 pushes the corrugated wire to slide will be greater than the deformation of the preset pressing depression of the corrugated wire. Based on this, this solution sets the distance between the end face of the pressing end 202 close to the end that pushes the corrugated wire to slide and the temperature control space to be smaller than the distance between the end face of the pressing end 202 away from the end that pushes the corrugated wire to slide and the temperature control space, so that after the pressing end 202 presses the corrugated wire, the heat of the end face of the pressing end 202 close to the end that pushes the corrugated wire to slide will be transferred to the pressing depression of the corrugated wire, and then during the period when the pressing end 202 pushes the corrugated wire to move, since the heat of the end face of the pressing end 202 close to the end that pushes the corrugated wire to slide has been transferred to the pressing depression of the corrugated wire when pressing the corrugated wire, at this time, the heat of the end face of the pressing end 202 close to the end that pushes the corrugated wire to slide has decreased, so that during the period when the end face of the pressing end 202 close to the end that pushes the corrugated wire to slide is in contact with the pressing depression of the corrugated wire, the deformation of the pressing depression of the corrugated wire will not further expand.It should be noted that since the distance between the end face of the pressing end 202 close to the end face that pushes the corrugated wire to slide and the temperature control space is small, the total amount of heat on the end face of the pressing end 202 close to the end face that pushes the corrugated wire to slide is small. After the heat on the end face of the pressing end 202 close to the end face that pushes the corrugated wire to slide decreases, since the time for the pressing end 202 to push the corrugated wire to move is short, during this time, the heat transferred from the temperature control space to the end face of the pressing end 202 close to the end face that pushes the corrugated wire to slide is limited, and then when the end face of the pressing end 202 close to the end face that pushes the corrugated wire to slide and the pressing depression of the corrugated wire are in contact with each other, the deformation of the pressing depression of the corrugated wire will not expand further, thereby avoiding the dimensional accuracy and surface quality of the corrugated wire affected by excessive temperature fluctuations.

[0040] Furthermore, in order to realize the rotation of the buckling lower roller 3, the present scheme also includes a rotating unit 5, which includes a rotating motor 501, a rotating belt 502, a rotating shaft 503, a rotating gear 504 and a driving gear 505. The rotating motor 501 is arranged in the processing frame 1, the rotating shaft 503 is coaxially arranged at one end of the buckling lower roller 3, the driving gear 505 is coaxially arranged on the rotating shaft 503, and the rotating gear 504 is coaxially arranged on the rotating motor 501. The rotating belt 502 is meshed and connected with the rotating gear 504 and the driving gear 505 respectively; by providing the rotating motor 501, when the rotating motor 501 starts working, it will control the rotating gear 504 to rotate. Since the rotating belt 502 is meshed and connected with the rotating gear 504 and the driving gear 505 respectively, the rotation of the rotating gear 504 will drive the rotating belt 502 to rotate, thereby realizing the rotation of the driving gear 505, and realizing the rotation of the rotating shaft 503 and the buckling lower roller 3.

[0041] It should be noted that the heating component 4 of this scheme will also control the temperature of the buckling lower roller 3. In order to achieve temperature control of the buckling lower roller 3, the structure of the buckling lower roller 3 of this scheme is consistent with the structure of the buckling upper roller 2. The heating component 4 also includes an input pipe 406, an output pipe 407 and a second one-way valve 408. The two ends of the input pipe 406 are rotatably coaxially connected to the heat pump 402 and the end of the buckling lower roller 3 away from the rotating shaft 503. The input pipe 406 is connected to the temperature control space of the buckling lower roller 3. The two ends of the output pipe 407 are rotatably coaxially connected to the heat conduction tank 401 and the other end of the rotating shaft 503. The interior of the rotating shaft 503 is hollow, and the interior of the rotating shaft 503 is connected to the temperature control space of the buckling lower roller 3. The two parts are connected with each other, and the second one-way valve 408 is sealed at the connection between the output pipe 407 and the rotating shaft 503; through such a setting, when the heat pump 402 starts to work, the heat-conducting oil in the heat-conducting tank 401 will flow to the temperature-controlled space of the buckling lower roller 3 through the input pipe 406, and then the heat-conducting oil in the temperature-controlled space inside the buckling lower roller 3 will flow back into the heat-conducting tank 401 through the output pipe 407. It should be noted that, in order to ensure the flow direction of the hydraulic oil, the present solution is further provided with two second one-way valves 408, and the two second one-way valves 408 are respectively sealed at the connection between the heat pump 402 and the input pipe 406 and the connection between the output pipe 407 and the heat-conducting tank 401. It is also worth mentioning that in this solution, the input pipe 406 and the output pipe 407 are respectively rotatably coaxially arranged at the two ends of the buckling lower roller 3. Such an arrangement can ensure that during the rotation of the buckling lower roller 3, the rotation of the buckling lower roller 3 will not affect its connection relationship with the output pipe 407 and the input pipe 406, nor will the rotation of the buckling lower roller 3 cause the output pipe 407 and the input pipe 406 to rotate together, thereby causing the output pipe 407 and the input pipe 406 to fail to work normally.

[0042] In addition, in order to adjust the gap between the buckling upper roller 2 and the buckling lower roller 3, the present invention further includes a lifting assembly 6, which includes a lifting hydraulic cylinder 601, a lifting plate 602, a linkage shaft 603 and a connecting rod 604. The lifting hydraulic cylinder 601 is vertically arranged in the processing frame 1, the lifting plate 602 is connected to the output end of the lifting hydraulic cylinder 601, and the connecting rod 604 is coaxially arranged at one end of the buckling upper shaft 201. A rotating slot is provided at one end of the linkage shaft 603, and one end of the linkage shaft 603 is connected to the lifting plate 602. The other end of the linkage shaft 603 is rotated by The movable slot hole is coaxially connected to the connecting rod 604; by providing a lifting hydraulic cylinder 601, when the lifting hydraulic cylinder 601 starts to work, the lifting plate 602 will rise and fall following the lifting of the output end of the lifting hydraulic cylinder 601, thereby driving the linkage shaft 603 to rise and fall following the lifting plate 602. Since the other end of the linkage shaft 603 is coaxially connected to the connecting rod 604 through the rotating slot hole, the connecting rod 604 will also rise and fall following the lifting of the linkage shaft 603, thereby realizing the lifting and lowering control of the upper buckling roller 2 and adjusting the gap between the upper buckling roller 2 and the lower buckling roller 3.

[0043] Furthermore, in order to realize the rotation of the buckling upper roller 2, the present solution further includes a driving unit 7, which includes a driving motor 701, a driving gear 702, a control gear 703 and a driving belt 704. The driving motor 701 is arranged on the lifting plate 602, the driving gear 702 is coaxially connected to the output end of the driving motor 701, the control gear 703 is coaxially sleeved on the connecting rod 604, and the driving belt 704 is respectively meshed with the driving gear 702 and the control gear 703; by providing the driving motor 701, when the driving motor 701 starts working, it will control the driving gear 702 to rotate, and due to the driving belt 704 They are respectively meshed and connected with the driving gear 702 and the control gear 703, so the driving gear 702 will drive the driving belt 704 to rotate, and then drive the control gear 703 to move, thereby realizing the rotation of the upper bending roller 2; it should be noted that, in this scheme, one end of the oil guide pipe 403 is rotatably coaxially connected to the end of the upper bending shaft 201 away from the connecting rod 604, the oil guide pipe 403 is interconnected with the temperature control space of the upper bending roller 2, and the interior of the connecting rod 604 is hollow, and the connecting rod 604 is interconnected with the other end of the temperature control space of the upper bending roller 2, and one end of the oil drain pipe 404 is rotatably connected to the other end of the connecting rod 604. Through such a setting, it can be ensured that during the rotation of the buckling upper roller 2, the rotation of the buckling upper roller 2 will not affect its connection with the oil guide pipe 403 and the oil drain pipe 404, nor will the rotation of the buckling upper roller 2 cause the oil guide pipe 403 and the oil drain pipe 404 to rotate together, causing the oil guide pipe 403 and the oil drain pipe 404 to malfunction.

[0044] According to the above embodiments, it can be known that the distance between the upper buckling roller 2 and the lower buckling roller 3 in this scheme will change. Since the upper buckling roller 2 and the lower buckling roller 3 in this scheme realize the pressing treatment of the straight wire by mechanical pressing, and at the same time, the contact temperature of the upper buckling roller 2 and the lower buckling roller 3 on the corrugated wire realizes the buckling and shaping treatment of the straight wire after the pressing treatment; first, the space between the upper buckling roller 2 and the lower buckling roller 3 is defined as the gap space. In the actual process, since the distance between the upper buckling roller 2 and the lower buckling roller 3 is too small, the height of the gap space is also small, and the surface temperature of the upper buckling roller 2 and the surface temperature of the lower buckling roller 3 are less affected by the temperature of the gap space; when the distance between the upper buckling roller 2 and the lower buckling roller 3 is too large, the height of the gap space increases accordingly, and then, the surface temperature of the upper buckling roller 2 and the surface temperature of the lower buckling roller 3 are greatly affected by the temperature of the gap space. At the same time, it should also be noted that, since the device of this scheme will perform bending and shaping treatment on multiple straight wires at the same time, this device cannot directly seal the gap space to maintain the temperature of the gap space; based on this, in order to solve the problem that when the height of the bending upper roller 2 is raised, the height of the gap space becomes larger, because the temperature of the gap space has a temperature difference with the surface of the bending upper roller 2 or the surface of the bending lower roller 3, and thus the gap space affects the surface temperature of the bending upper roller 2 and the surface temperature of the bending lower roller 3, this scheme also includes a heat insulation cover 8, the heat insulation cover 8 includes a heat insulation body 801, a heat insulation block 802 and a heat insulation rod 803, and the heat insulation body 801 is slidably and sealedly arranged in the bending space The two ends of the insulation rod 803 are respectively connected to the insulation body 801 and the lifting plate 602. The insulation body 801 is located between the top of the buckling upper roller 2 and the lifting plate 602. The linkage shaft 603 passes through the insulation body 801 to realize its connection with the connecting rod 604. At the same time, the insulation body 801 is provided with an insulation slot; the insulation block 802 is erected in the buckling space, the insulation block 802 is located between the lifting plate 602 and the insulation body 801, the insulation block 802 is located directly above the insulation slot, and the cross-sectional shape of the insulation block 802 is consistent with the cross-sectional shape of the insulation slot. The insulation block 802 can lock or release the mutual sealing relationship between it and the insulation slot of the insulation body 801. First, the space between the insulation body 801 and the buckling lower roller 3 is defined as the working space. Since the insulation body 801 is slidably sealed in the buckling space, and the two ends of the insulation rod 803 are respectively connected to the insulation body 801 and the lifting plate 602, in fact, the height change of the working space is consistent with the height change of the gap space.With this arrangement, when the height of the gap space is relatively low, the insulation block 802 releases its mutual sealing relationship with the insulation slots of the insulation body 801. Firstly, such an arrangement, on the one hand, is because when the height of the gap space is relatively low, the surface temperature of the buckling upper roller 2 and the surface temperature of the buckling lower roller 3 are less affected by the temperature of the gap space; secondly, with this arrangement, due to the wind pressure generated by the rotation of the buckling upper roller 2, the airflow in the gap space is transferred into the buckling space through the insulation slots, increasing the temperature of the remaining space in the buckling space. When the height of the lifting plate 602 is raised, it not only controls the height increase of the buckling upper roller 2, but also controls the height increase of the insulation body 801. When the lifting plate 602 is raised to its highest height, the insulation block 802 will achieve its sealing relationship with the insulation slots. It should be noted that when the lifting plate 602 is lifted to the highest height, the gap between the insulation block 802 and the insulation slot will gradually become smaller, and the corresponding airflow in the gap space will flow more in the working space, while less airflow will flow through the gap between the insulation block 802 and the insulation slot to the rest of the space in the buckling space, which can make the temperature in the working space reach the same level as the surface temperature of the buckling upper roller 2 in a shorter time. At the same time, it is also worth noting that such a setting can also increase the temperature rise in the rest of the space in the buckling space. When the height of the working space is raised, the rest of the space in the buckling space will be incorporated into the working space, which will slow down the temperature drop trend of the working space after lifting, and can make the temperature in the working space reach the preset temperature in a shorter time, reducing the influence of the gap space temperature on the surface temperature of the buckling upper roller 2 and the surface temperature of the buckling lower roller 3.

[0045] Furthermore, the heat insulation cover 8 of this embodiment also includes an arc ring 804, which is arranged in a ring at the fitting position between the heat insulation body 801 and the buckling space; the cross-sectional shape of the arc ring 804 is an arc, and its top end is fitted with the bottom surface of the heat insulation body 801, while the tangent direction of the bottom end of the arc ring 804 points to the direction of the buckling upper roller 2. Through such an arrangement, when the air flow flowing in the buckling space does not flow out of the working space through the gap between the heat insulation block 802 and the heat insulation slot hole, the air flow flowing in the buckling space will slide through the top end of the arc ring 804 to the bottom end of the arc ring 804, and then flow back to the surface of the buckling upper roller 2, further reducing the influence of the temperature difference in the gap space on the surface temperature of the buckling upper roller 2.

[0046] In addition, it should be noted that the buckling lower roller 3 of this solution is located at the bottom end of the buckling space, and the input port provided on the processing frame 1 of this solution, that is, the position where the straight wire is input into the buckling space, the bottom surface height of the input port is equal to the top height of the buckling lower roller 3. At the same time, such a setting, since the buckling lower roller 3 will not change in height, in fact, the height change of the gap space has little effect on the surface temperature of the buckling lower roller 3. This solution only needs to solve the effect of the height change of the gap space on the surface temperature of the buckling upper roller 2, and can realize the effect of the height change of the gap space on the buckling shaping effect of the straight wire.
