Description

Technical Field

[0001] The present application relates to the technical field of wire straightening, and in particular to a bent wire straightening device and a straightening method. Background Art

[0002] At present, in order to facilitate transportation, metal wires and alloy wires are generally processed into linear shapes after production or before further production and processing. However, due to various factors during transportation, storage and processing, wires often have problems such as bending and deformation. Especially for softer copper, aluminum, magnesium, titanium wires and alloy wires, they are prone to bumping, deformation or bending, which not only affects the use of the wires, but also may pose a potential threat to the structure, quality and safety of the product. Therefore, it is particularly important to straighten the bent wires on site during processing or secondary use.

[0003] Traditional straightening methods are mostly carried out manually or with simple mechanical devices. These methods have problems such as low efficiency, poor straightening effect, and complex operation, which are difficult to meet the needs of modern construction sites or factories for efficient and precise straightening. Especially when dealing with alloy wires or metal wires, due to the large number and large volume, traditional methods often seem to be unable to cope with the situation, consuming a lot of manpower and material resources, resulting in low work efficiency. Summary of the invention

[0004] In order to improve work efficiency, the present application provides a bent wire straightening device.

[0005] In a first aspect, the present application provides a bent wire straightening device, which adopts the following technical solution: A bent wire straightening device, a base, placed on the ground, for forming a stable foundation; A first straightening roller is rotatably disposed on the base and is provided with a first straightening groove along the circumferential direction; A second straightening roller is rotatably disposed on the base, is disposed corresponding to the first straightening roller, and is provided with a second straightening groove along the circumferential direction, wherein the second straightening groove cooperates with the first straightening groove to form a straightening space; The driving mechanism is arranged on the base and is used for driving the first straightening roller and the second straightening roller to rotate in opposite directions.

[0006] By adopting the above technical solution, the head of the bent wire is pulled out and extended into the straightening space between the first straightening roller and the second straightening roller, and then the first straightening roller and the second straightening roller are driven to rotate by the driving mechanism to straighten the wire.

[0007] Through the above-mentioned settings, continuous and automatic straightening of bent wires is achieved, straightening efficiency is improved, and manual operations are reduced. Compared with traditional manual or simple mechanical straightening, this solution provides a more efficient straightening method and improves work efficiency.

[0008] Optionally, a pre-straightening mechanism is further provided on the base, and the pre-straightening mechanism comprises: A fixing frame, arranged on the base; A pre-straightening frame, arranged on the fixed frame; There are two pre-straightening rollers, both of which rotate on the pre-straightening frame, and the two pre-straightening rollers are inclined along the direction of the wire, and the height of the pre-straightening roller close to the wire is lower than the height of the pre-straightening roller far away from the wire.

[0009] By adopting the above technical scheme, the wire is preliminarily straightened before formal straightening to reduce large curvature bending. The inclined setting can alleviate the excessive angle of the initial straightening, which causes stress damage to the wire. After the preliminary straightening, subsequent straightening is convenient, the straightening accuracy is improved, and the wear of the straightening roller is reduced. The inclined pre-straightening roller adapts to the natural bending state of the wire. The pre-straightening step is increased, the overall straightening effect is improved, and the straightening efficiency is improved.

[0010] Optionally, the pre-straightening mechanism further comprises: A first straightening roller is rotatably mounted on the fixing frame and is provided with a first straightening groove along the circumferential direction; The second straightening roller is rotatably arranged on the fixing frame, is arranged corresponding to the first straightening roller, and is provided with a second straightening groove along the circumferential direction. The second straightening groove cooperates with the first straightening groove to form a straightening space.

[0011] By adopting the above technical scheme, the position of the wire is further adjusted after pre-straightening to ensure that the wire is in the correct position when entering the main straightening space; the utilization rate of the straightening space is improved, and the straightening failure rate is reduced. The design of the straightening groove ensures the stability of the wire during the straightening process; the addition of the straightening roller improves the controllability of the straightening process and enhances the straightening effect. The setting of the straightening groove corrects the wire again, so that the movement trajectory of the wire is fixed, which reduces the jump during straightening, improves the straightening accuracy, and improves work efficiency.

[0012] Optionally, a striking assembly is provided on the fixing frame, and the striking assembly includes: A rotating rod, rotatably disposed on the fixing frame and extending along the moving direction of the wire; A striking block is disposed on the rotating rod and abuts against a side wall of the wire close to the base; The elastic member is arranged on the fixing frame and connected with the rotating rod, and is used for driving the rotating rod to approach the wire.

[0013] By adopting the above technical solution, the wire is struck during the pre-straightening process to remove surface stress. The setting of the elastic part ensures continuous contact between the striking block and the wire, thereby improving the mechanical properties and surface quality of the wire. During the pre-straightening process, the striking action helps to release the residual stress inside the wire.

[0014] Optionally, the striking component further comprises: A toggle rod is slidably disposed on a side wall of the pre-straightening roller away from the wire and rotates with the pre-straightening roller, and is provided with a guide surface; the guide surface can abut against the rotating rod to drive the rotating rod to rotate; A limit block, disposed on the fixing frame, for limiting the rotation angle of the rotating rod; A reset member is arranged on the pre-straightening roller and connected to the toggle rod, and is used for driving the toggle rod to move away from the pre-straightening roller.

[0015] By adopting the above technical scheme, the rotation of the pre-straightening roller is used to drive the rotation of the rotating rod, and the limit block and the reset member control the rotation angle and reset of the rotating rod, thereby realizing the automation and periodicity of the tapping action, improving the stability and reliability of the tapping assembly, and improving the degree of automation of the straightening process. Compared with manual tapping, this scheme removes stress on the wire surface more evenly and effectively.

[0016] Optionally, the base is further provided with an auxiliary mechanism, and the auxiliary mechanism includes: The scraper is arranged on a side of the first straightening roller close to the wire entry end and abuts against a side wall of the wire away from the base.

[0017] By adopting the above technical solution, the scraper cleans the upper side of the wire to remove waste chips, and cooperates with the knocking block to complete the entire cleaning of the wire, reducing the debris or oxides from entering the subsequent straightening wheel, reducing damage to the wire, and at the same time maintaining the straightening accuracy.

[0018] Optionally, the auxiliary mechanism further includes: A support rod is arranged on the base and is parallel to the axis of the straightening space. A penetration groove is provided on the scraper, and the penetration groove is sleeved on the support rod. The scraper freely hangs on the support rod in a vertical direction. When the scraper contacts the side wall of the wire away from the base, the penetration groove does not contact the support rod.

[0019] By adopting the above technical solution, the support rod and the penetration groove ensure the stability and flexibility of the scraper, improve the surface quality of the wire, reduce the rigidity of subsequent use, and the design of the scraper adapts to wires of different diameters. At the same time, it reduces the hard contact between the residual waste or oxide on the wire and the scraper, which causes scraper damage.

[0020] Optionally, the contact surface between the scraper and the wire is elastic and insulated, and the scraper is conductive; a connecting groove is provided on the scraper, and the connecting groove is provided in a vertical direction, and the auxiliary mechanism further comprises: A connecting rod, the connecting rod is arranged on the base and is parallel to the supporting rod, and the side wall of the connecting groove is tangent to and in contact with the connecting rod; A power source is provided between the connecting rod and the supporting rod, and the connecting rod and one end of the supporting rod are connected through a first wire and a second wire, and the other end of the connecting rod and the supporting rod can be connected through a scraper to form a closed loop; The first indicator light is arranged on the second wire between the power source and the support rod.

[0021] By adopting the above technical scheme, good contact between the scraper and the wire is ensured. After the wire is separated from the scraper, the scraper falls freely, so that the connecting rod, power supply, support rod and indicator light form a closed loop, indicating that the scraper and the wire are not in contact, and real-time monitoring of the surface quality of the wire is realized. It can monitor when a wire is straightened or when the wire is broken, so as to stop the equipment in time, replace the wire, and arrange the subsequent work in time, so as to improve work efficiency and improve the safety and reliability of the straightening process. This scheme can detect problems on the wire surface more timely and accurately.

[0022] Optionally, a damage detection component is further provided on the base, and the damage detection component includes: Two fixing blocks are provided and both are arranged on the base, and the two fixing blocks correspond to the two sides of the scraper one by one; a third wire, used to connect the power source, the fixing block and the connecting rod; A second indicator light is arranged on the third wire; Two insulating sheets are provided, the two insulating sheets correspond to the two sides of the scraper one by one, are in contact with the fixed block, and are provided with sliding holes; A striker is disposed on the scraper and is conductively connected to the scraper, and slides in the sliding hole. When the scraper is tilted, the striker passes through the sliding hole and abuts against the fixed block; The elastic support is arranged between the insulating sheet and the scraper, is used to connect the insulating sheet and the scraper, and has elasticity.

[0023] By adopting the above technical solution, when the wire is not completely broken and straightened, the scraper contacts the surface defect of the wire and moves relative to it. The surface defect clamps the scraper, which increases the friction, so that the end of the scraper that contacts the wire moves with the movement of the wire, and the scraper drives the striker to pass through the sliding hole and contact the fixed block, so that the second indicator light is energized to remind the staff and mark it, which is convenient for subsequent cutting of the wire, reduces the use of damaged parts in the construction site, and improves the construction quality.

[0024] In a second aspect, the present application provides a wire straightening method, which adopts the following technical solution: A wire straightening method comprises the following steps: Pre-straightening treatment: After the wire is drawn out, it is pre-straightened to initially eliminate large curvature bends; Dynamic tapping stress relief: When the wire is pre-straightened, the wire surface is periodically tapped and impacted at a preset frequency to peel off the surface oxide layer and release local stress, and the surface debris is scraped off; Main straightening process: The wire enters the straightening space formed by the first straightening roller and the second straightening roller. The first straightening roller and the second straightening roller rotate in opposite directions, and the wire is straightened through the continuous extrusion of the first straightening groove and the second straightening groove.

[0025] By adopting the above technical scheme, including the steps of wire pre-straightening treatment, dynamic tapping stress relief, main straightening processing and other steps, efficient and precise straightening of bent wires is achieved, the comprehensive performance and quality of the wires are improved, and the straightening efficiency and quality are improved.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. It realizes continuous and automatic straightening of bent wires, improves straightening efficiency, and reduces manual operations. Compared with traditional manual or simple mechanical straightening, this solution provides a more efficient straightening method and improves work efficiency; 2. When the wire is not completely broken and straightened, the scraper contacts the surface defect of the wire and moves relative to it. The surface defect clamps the scraper, which increases the friction. As a result, the end of the scraper that contacts the wire moves with the movement of the wire. The scraper drives the striker through the sliding hole and contacts the fixed block, so that the second indicator light is energized to remind the staff and mark it, which is convenient for subsequent wire cutting, reduces the use of damaged parts in the construction site, and improves the construction quality.

The first pre-straightening roller 630 and the second pre-straightening roller 630 pre-straighten the wire to preliminarily eliminate large curvature bends; Dynamic tapping stress relief: When the wire is pre-straightened, as the pre-straightening roller 630 rotates, the pre-straightening roller 630 drives the toggle rod 663 to push the rotating rod 661 to rotate, and the rotating rod 661 drives the striking block 662 to overcome the torsion force of the torsion spring and move away from the wire until the rotating rod 661 conflicts with the limit block 664, and the toggle rod 663 approaches the pre-straightening roller 630 through the guidance of the guide surface, so that the rotating rod 661 is separated from the toggle rod 663, and the torsion spring drives the rotating rod 661 to approach the wire, and the striking block 662 strikes the wire, and then fits with the wire. During the movement of the wire, the striking block 662 swings slightly under the friction with the wire, and strikes the wire slightly. As the pre-straightening roller 630 rotates continuously, the surface of the wire is periodically struck and impacted at a preset frequency, the surface oxide layer is peeled off and the local stress is released, and the surface debris is scraped off. Main straightening process: The wire enters the straightening space formed by the first straightening roller 300 and the second straightening roller 400, and the driving mechanism 500 drives the first straightening roller 300 and the second straightening roller 400 to rotate in opposite directions, and the wire is straightened through the continuous extrusion action of the first straightening groove 310 and the second straightening groove 410.

[0050] Condition monitoring: During the wire straightening process, the wire is inspected for cracks, pits or other damages;

[0051] The implementation principle of this embodiment is: the bent wire passes through the clamping wheel 680 and the pre-straightening roller 630, then passes between the first straightening roller 640 and the second straightening roller 650, and then extends into between the first straightening roller 300 and the second straightening roller 400.

[0052] Or fix the wire bundle on the expansion shaft 230 of the rotating seat 200, and the operator puts the wire bundle on the air shaft (expansion shaft 230), expands the air shaft by inflating, and clamps the inner wall of the wire bundle; fix the second bracket 220 on the sliding seat 810 by bolts, ensure that the support ring and the rotating bearing of the expansion shaft 230 are concentrically abutted to provide stable support; adjust the position of the sliding seat 810 to adapt to the length of the wire bundle, start the first adjusting cylinder 820 on the base 100, and push the sliding seat 810 to slide on the base 100 until the end of the wire bundle is aligned with the pre-straightening mechanism 600, pass the wire end through the pre-straightening mechanism 600, and manually pull the wire end through: the straightening space formed by the first straightening roller 640 and the second straightening groove to ensure that the wire is horizontally centered.

[0053] The pre-straightening roller 630 has an arc-shaped pre-straightening groove. The pre-straightening roller 630 is tilted, and the roller height close to the expansion shaft 230 is lower, which gradually straightens the wire and bends it. The height of the pre-straightening frame 620 is adjusted by the second adjusting cylinder 670 to match the pre-straightening groove with the wire diameter.

[0054] The wire passes through the main straightening roller group, and the end of the wire is introduced into the straightening space formed by the first straightening groove 310 and the second straightening groove 410 to ensure that the wire is centered. The position of the second straightening roller 400 is adjusted according to the diameter of the wire: loosen the bolts on the mounting seat 840, turn the adjusting bolt 850, and push the adjusting seat 830 up and down along the sliding hole until the straightening space matches the wire diameter, and then tighten the bolts.

[0055] The driving mechanism 500 is started for straightening, and the driving motor is turned on to drive the first straightening roller 300 to rotate through the chain and the sprocket. The second straightening roller 400 rotates in the opposite direction due to the friction force, pulling the wire to move forward.

[0056] If a servo motor is used to drive the expansion shaft 230, the servo motor is started to actively rotate the wire bundle for feeding. If no external servo motor is provided, the wire bundle is passively rotated by relying on the traction force of the straightening roller.

[0057] When the wire passes through the pre-straightening roller 630, the toggle rod 663 on the side wall of the pre-straightening roller 630 periodically pushes the rotating rod 661 as it rotates, driving the striking block 662 to strike the surface of the wire at a high frequency to release the straightening stress; the elastic member (torsion spring) ensures that the striking block 662 is always in contact with the wire, and the limit block 664 limits the rebound amplitude of the rotating rod 661.

[0058] The wire passes through the trigger slot 713 of the scraper 710, and the scraper 710 is lifted up by the wire and is in a high position (the upper wall of the trigger slot 713 is elastically insulated). When the wire breaks or detaches, the scraper 710 falls freely: the groove 711 is in conductive contact with the support rod 720, triggering the first indicator light 750 to light up, prompting the operator to check for abnormalities, and the edge of the scraper 710 scrapes off oxides or debris on the surface of the wire.

[0059] If there are protrusions or cracks on the surface of the wire, the scraper 710 squeezes the elastic support, pushing the striker 785 through the sliding hole 787 of the insulating sheet 784 and making conductive contact with the fixing block 781; the circuit conduction triggers the second indicator light 783 to light up, indicating that the wire is damaged.

[0060] After the straightening is completed, the drive motor and the servo motor are stopped, the air is deflated and the air shaft is contracted, the wire bundle is removed, and the residues on the straightening roller and the scraper 710 are cleaned.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
