Description

Technical Field

[0001] The present invention belongs to the technical field of wire straightening devices, and specifically relates to a wire straightening device and method based on the processing of metal wires. Background Art

[0002] In modern industrial production, metal wires such as magnesium copper titanium alloy wires, titanium alloy wires, and copper alloy wires are widely used in many key fields such as aerospace, electronic communication, and mechanical manufacturing. The performance and precision of these metal wires directly affect the quality and reliability of downstream products.

[0003] However, during the production process of metal wires, such as in rolling, drawing, transportation, or storage, due to various external forces and uneven internal stress distribution in the material, the wires often have various degrees of shape defects such as bending, twisting, and waviness. Taking titanium alloy wires as an example, they have excellent properties such as high strength and corrosion resistance, but during the drawing process, due to the friction of the die and the plastic deformation of the material, it is easy for the wires to have local bending or overall twisting. For copper alloy wires, during the rolling process, the change in temperature and uneven distribution of rolling force will also cause shape deviation of the wires. And as a complex alloy wire, magnesium copper titanium alloy wires have a greater possibility of deformation due to the distribution difference of internal alloy components and the action of thermal stress during the processing.

[0004] The existence of these shape defects brings many problems. On the one hand, the deformed wires are difficult to operate accurately in subsequent processes such as winding and welding, affecting production efficiency and product quality; on the other hand, for some application scenarios with extremely high precision requirements, such as the precision instrument connection wires in the aerospace field, shape defects may cause the electrical performance, mechanical performance, etc. of the wires not to meet the requirements, and even pose safety hazards.

[0005] Currently, for the correction of metal wires, traditional methods mainly include mechanical correction and manual correction, etc. Mechanical correction usually uses a simple roller straightening machine, and the correction of the wire is achieved by the extrusion and bending of multiple groups of rollers. However, this method has limited correction effect on complex alloy wires such as magnesium copper titanium alloy, and it is easy to cause insufficient correction. Manual correction depends on the experience and operation skills of workers, with low efficiency and unstable correction quality, and cannot meet the requirements of large-scale industrial production.

[0006] Therefore, in order to improve the correction accuracy and production efficiency of metal wires such as magnesium copper titanium alloy wires, titanium alloy wires, and copper alloy wires, it is urgent to develop a wire straightening device based on the processing of metal wires. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a wire straightening device for processing metal wires that can overcome or at least partially solve the above problems.

[0008] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: a wire straightening device for processing metal wires, including a mounting plate, and further including: a plurality of connecting frames arrayed along the length direction of the mounting plate, and each connecting frame is provided with an upper guide wheel; a positioning guide wheel is mounted on the mounting plate on one side of the upper guide wheel; a lower guide wheel is rotatably connected to the mounting plate on the lower side of the positioning guide wheel, and the wire passes upward from the lower guide wheel around the positioning guide wheel and the upper guide wheel, so that the wire is in a wavy shape in the first perspective; a driving component is used to drive the connecting frame to move upward and laterally, so that the wire is in a wavy shape in the second perspective and obliquely upward in the third perspective, so that the wire is straightened along a three-dimensional wavy path in three perspectives.

[0009] Preferably, the bottom of the connecting frame is fixedly connected with a multi-faceted rod, and a chute is opened on the mounting plate corresponding to the multi-faceted rod, and the multi-faceted rod slides in the chute. The multi-faceted rods on the plurality of connecting frames are connected by a cross plate, and a second spring is connected to the cross plate.

[0010] Preferably, the driving component includes a cam member, and the cam member is located below the cross plate and is used to drive the connecting frame to move upward.

[0011] Preferably, the plurality of connecting frames are connected by a rear plate member, and an installation block is fixedly connected to the rear plate member. Oblique guide grooves are symmetrically opened on the installation block, and convex columns are symmetrically and fixedly connected to the connecting plate. The convex columns correspond to the installation block and are used to drive the connecting frame to move laterally; the cam member and the connecting plate are connected by a synchronous belt drive.

[0012] Preferably, a vertical plate is fixedly connected to the mounting plate, and a first spring is fixedly connected to the rear plate member. The end of the first spring away from the rear plate member abuts against the vertical plate.

[0013] Preferably, an adjusting block is fixedly connected to the connecting frame, and a connecting arm is connected to the adjusting block through an adjusting bolt, and the upper guide wheel is rotatably connected to the connecting arm.

[0014] Preferably, a cavity is opened in the upper guide wheel, and the cavity is supplied with gas by a supply pipe, and first air holes are circumferentially opened on the outer periphery of the upper guide wheel.

[0015] Preferably, second air holes are circumferentially opened on the outer periphery of the upper guide wheel, and the axis of the second air holes passes through the axis of the first air holes.

[0016] Preferably, a spiral flow guide plate is fixedly connected in the cavity.

[0017] A method for using a wire straightening device based on the processing of metal wires includes the following steps:

[0018] S1. Pass the wire upward from the lower guide wheel around the positioning guide wheel and the upper guide wheel, making the wire wavy in the first perspective to initially release the residual stress.

[0019] S2. The motor drives the cam member to rotate, reciprocally pushing the cross plate to move the connecting frame up and down, increasing the distance between the upper guide wheel and the lower guide wheel to further release the residual stress of the wire; the cam member drives the connecting plate to rotate through a synchronous belt or a chain drive, and its convex column pushes the connecting frame to shift laterally through the inclined guide groove of the mounting block, cooperating with the up and down movement.

[0020] S3. The combination of the upward movement and lateral movement of the connecting frame makes the wire displace obliquely upward in the third perspective; the wire is restricted by the positioning guide wheel and is wavy in the second perspective. Combining with the wavy shape in the first perspective, a three-dimensional wavy straightening path is formed.

[0021] S4. The air supply pipe pumps gas into the cavity through the air inlet passage. After being accelerated by the spiral flow guide plate, it is ejected from the first air hole and the second air hole. The airflow collides and scatters to clean the impurities on the surface of the wire, and at the same time cools the wire.

[0022] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0023] 1. For the wire straightening device based on the processing of metal wires, the wire passes upward from the lower guide wheel around the positioning guide wheel and the upper guide wheel. Under the action of high-speed wire winding of the take-up wheel, the wire moves between the lower guide wheel, the upper guide wheel and the positioning guide wheel, presenting a wavy shape to release the residual stress of the wire; the cam member and the connecting plate are connected by a synchronous belt or a chain drive, and the connecting plate has the same shape and size as the cam member. Therefore, when the connecting plate rotates, the convex column pushes the connecting frame to shift laterally on the upper side of the mounting plate through the inclined guide groove and cooperates with the upward movement of the connecting frame to achieve an inclined upward displacement in the third perspective (refer to Figure 7 perspective, that is Figure 4 the right view angle). When the wire makes an inclined upward displacement, the wire is restricted by the positioning guide wheel and is wavy in the second perspective (that is Figure 4 the top view angle) (refer to Figure 6 ). Therefore, the first perspective, the second perspective and the third perspective together form a three-dimensional wavy path.

[0024] 2. Wire straightening devices, based on metal wire processing, can effectively address shape defects such as bending, twisting, and waving that occur during rolling and drawing. They are highly effective in straightening complex alloy wires, such as magnesium-copper-titanium alloys, improving the wire's precision and quality. High degree of automation: Automated straightening eliminates the need for manual operation, thus avoiding the inefficiency of manual straightening. This system can meet the needs of large-scale industrial production. Guaranteed stable straightening quality: It eliminates reliance on worker experience and operational skills, reducing the impact of human factors on straightening quality. This ensures the stability of straightening quality, thereby ensuring the quality and reliability of downstream products.

[0025] 3. Wire straightening devices based on metal wire processing use an air blowing mechanism on the upper guide wheel to remove impurities from the wire surface, preventing them from affecting subsequent processing steps and wire performance. The air flow cools the wire, reducing thermal stress during processing. The air flow also assists in wire deformation during the straightening process, further improving straightening efficiency.

Specific embodiments

[0037] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0038] Embodiment 1: Refer to Figures 1-9 , a wire straightening device for processing metal wires, including a mounting plate 1, and further including: a plurality of connecting frames 12 arranged in an array along the length direction of the mounting plate 1, and an upper guide wheel 124 is provided on each connecting frame 12; a positioning guide wheel 15 is mounted on the mounting plate 1 on one side of the upper guide wheel 124; a lower guide wheel 11 is rotatably connected to the mounting plate 1 below the positioning guide wheel 15, and the wire 10 bypasses the positioning guide wheel 15 and the upper guide wheel 124 upward from the lower guide wheel 11, so that the wire 10 is in a wavy shape in the first perspective; a driving component for driving the connecting frame 12 to move upward and laterally, so that the wire 10 is in a wavy shape in the second perspective and obliquely upward in the third perspective, so that the wire 10 is straightened in a three-dimensional wavy path in three perspectives.

[0039] The bottom of the connecting frame 12 is fixedly connected with a multi-faceted rod 125, a chute 127 is opened on the mounting plate 1 corresponding to the multi-faceted rod 125, the multi-faceted rod 125 slides in the chute 127, and the multi-faceted rods 125 on the plurality of connecting frames 12 are connected by a cross plate 126, and a second spring 128 is connected to the cross plate 126.

[0040] The driving component includes a cam member 131, and the cam member 131 is located below the cross plate 126 for driving the connecting frame 12 to move upward.

[0041] A plurality of connecting frames 12 are connected to each other by a rear plate member 13. An installation block 134 is fixedly connected to the rear plate member 13. Oblique guide grooves 135 are symmetrically formed in the installation block 134. Convex columns 133 are symmetrically and fixedly connected to the connecting plate 132. The convex columns 133 correspond to the installation block 134 and are used to drive the connecting frame 12 to move horizontally. The cam member 131 and the connecting plate 132 are connected by synchronous belts or chains.

[0042] A vertical plate 14 is fixedly connected to the mounting plate 1. A first spring 141 is fixedly connected to the rear plate member 13. One end of the first spring 141 away from the rear plate member 13 abuts against the vertical plate 14. Further, a guide rod is provided on the rear plate member 13, and the first spring 141 is sleeved on the guide rod, so that the first spring 141 will not bounce off when being squeezed. The multi-faceted rods 125 at the bottom of the connecting frame 12 slide in the sliding grooves 127. A plurality of multi-faceted rods 125 are connected by a cross plate 126. The second spring 128 on the cross plate 126 plays a role in buffering and resetting. The first spring 141 on the rear plate member 13 abuts against the vertical plate 14 and also assists in the reset of the connecting frame 12.

[0043] An adjusting block 121 is fixedly connected to the connecting frame 12. A connecting arm 122 is connected to the adjusting block 121 through an adjusting bolt 123. An upper guide wheel 124 is rotatably connected to the connecting arm 122 and is used to adjust the height of the connecting arm 122.

[0044] When the device is in use, the wire 10 is paid out and wound up by a pay-off reel and a take-up reel. The wire 10 located between the take-up reel and the pay-off reel is wound around the lower guide wheel 11, the upper guide wheel 124, and the positioning guide wheel 15 located on the mounting plate 1.

[0045] The lower guide wheel 11, the upper guide wheel 124, and the positioning guide wheel 15 are all rotatably arranged. Through the high-speed winding of the take-up reel, the wire 10 moves between the lower guide wheel 11, the upper guide wheel 124, and the positioning guide wheel 15. Referring to Figure 4 , in the main view (that is, the first view), the wire 10 is in a wavy shape to release the residual stress of the wire 10.

[0046] By driving the cam member 131 to rotate through a motor, the cam member 131 reciprocally pushes the cross plate 126, so that the connecting frame 12 moves up and down. During the up and down movement, the distance between the upper guide wheel 124 and the lower guide wheel 11 increases, further improving the release of the residual stress of the wire 10.

[0047] The cam member 131 and the connecting plate 132 are connected by synchronous belts or chains, and the connecting plate 132 has the same shape and size as the cam member 131. Therefore, when the connecting plate 132 rotates, the convex column 133 pushes the connecting frame 12 to laterally move on the upper side of the mounting plate 1 through the oblique guide groove 135 and cooperates with the upward movement of the connecting frame 12 to achieve in the third view (referring to Figure 7 view, that isFigure 4 The wire 10 is restricted by the positioning guide wheel 15 when it is displaced obliquely upwards in the second viewing angle (i.e., the right viewing angle). Figure 4 The top view angle) is wavy (refer to Figure 6 ), so the first perspective, the second perspective, and the third perspective are combined into a three-dimensional wavy path.

[0048] Through three-dimensional wavy path straightening, the shape defects such as bending, twisting, and wavy shapes generated by metal wires during rolling and drawing can be effectively solved. It is especially effective for correcting complex alloy wires such as magnesium-copper-titanium alloys, thereby improving the accuracy and quality of the wire 10.

[0049] The device realizes automatic straightening without relying on manual operation, avoids the problem of low efficiency of manual correction, and can meet the needs of large-scale industrial production.

[0050] It gets rid of the dependence on workers' experience and operating skills, reduces the impact of human factors on the correction quality, ensures the stability of the correction quality, and thus ensures the quality and reliability of downstream products.

[0051] It should be understood that the device is also equipped with a counterweight to adjust the tightness of the wire 10 in real time.

[0052] Example 2: Reference Figure 4 , Figure 8 , Figure 9 , a wire straightening device based on the processing of metal wire, comprising a mounting plate 1, and further comprising: a plurality of connecting frames 12 arranged in an array along the length direction of the mounting plate 1, each connecting frame 12 being provided with an upper guide wheel 124; a positioning guide wheel 15 is installed on the mounting plate 1 located on one side of the upper guide wheel 124; a lower guide wheel 11 is rotatably connected to the mounting plate 1 located below the side of the positioning guide wheel 15, and the wire 10 passes upward from the lower guide wheel 11 around the positioning guide wheel 15 and the upper guide wheel 124, so that the wire 10 is wavy in a first viewing angle; a driving component is used to drive the connecting frame 12 to move upward and sideways, so that the wire 10 is wavy in a second viewing angle and obliquely upward in a third viewing angle, so that the wire 10 is straightened in a three-dimensional wavy path in three viewing angles, which is basically the same as Example 1, and further, a cavity 21 is opened in the upper guide wheel 124, and gas is supplied to the cavity 21 by the air supply pipe 2, and a first blowing hole 22 is opened on the circumference of the outer circumference of the upper guide wheel 124;

[0053] An air inlet 20 is provided at the axis of the upper guide wheel 124. The air supply pipe 2 pumps gas into the cavity 21 through the air inlet 20 and blows it toward the wire 10 from the first blowing hole 22 to remove impurities on the surface of the wire 10 and prevent the impurities from affecting subsequent processing steps and the performance of the wire 10.

[0054] On the outer circumference of the upper guide wheel 124, a second air blowing hole 23 is circumferentially provided. The axis of the second air blowing hole 23 passes through the axis of the first air blowing hole 22, and the gas discharged from the second air blowing hole 23 collides with the gas discharged from the first air blowing hole 22, causing the gas to disperse and expanding the cleaning range of the impurities on the surface of the wire 10.

[0055] In addition, the air flow of the blowing can also cool the wire 10, reduce the influence of thermal stress during the processing, or assist the deformation of the wire 10 during the straightening process, further improving the straightening effect.

[0056] A spiral guide plate 24 is fixedly connected in the cavity 21. The gas enters the center of the spiral guide plate 24 and is discharged from the first air blowing hole 22 and the second air blowing hole 23 in a rotating manner, which enables the gas to accelerate in the cavity 21 and further improves the cleaning effect of the impurities on the wire 10.

[0057] Example 3: Refer to Figures 1-9 , a wire straightening method, including the following steps:

[0058] S1. The wire 10 is wound upward from the lower guide wheel 11 around the positioning guide wheel 15 and the upper guide wheel 124, so that the wire 10 is in a wavy shape in the first perspective main view, and the residual stress is initially released.

[0059] S2. The motor drives the cam member 131 to rotate, reciprocally pushes the cross plate 126, and makes the connecting frame 12 move up and down, increasing the distance between the upper guide wheel 124 and the lower guide wheel 11, and further releasing the residual stress of the wire 10; the cam member 131 drives the connecting plate 132 to rotate through a synchronous belt or a chain drive, and its convex column 133 pushes the connecting frame 12 to move laterally through the inclined guide groove 135 of the mounting block 134, cooperating with the up and down movement.

[0060] S3. The combination of the upward movement and the lateral movement of the connecting frame 12 makes the wire 10 displace obliquely upward in the third perspective right view; the wire 10 is restricted by the positioning guide wheel 15 and is in a wavy shape in the second perspective top view, combining with the wavy shape in the first perspective to form a three-dimensional wavy straightening path.

[0061] S4. The air supply pipe 2 pumps gas into the cavity 21 through the air inlet passage 20. After being accelerated by the spiral guide plate 24, the gas is ejected from the first air blowing hole 22 and the second air blowing hole 23. The air flow collides and disperses to clean the impurities on the surface of the wire 10, and at the same time cools the wire 10.

[0062] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of the present invention can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content prompted above within the scope of the technical solution of the present invention.
