Description

Technical Field

[0001] This utility model relates to the field of continuous annealing rewinding machine technology, specifically a straightening device for a continuous annealing rewinding machine. Background Technology

[0002] In the production and processing of metal wire, the continuous annealing and rewinding machine plays a crucial role. Its main responsibility is to anneal the metal wire and then rewind it. Ensuring good straightness of the wire before winding is essential; otherwise, it will adversely affect subsequent use and product quality.

[0003] In existing straightening devices for continuous annealing and rewinding machines, the straightening rollers are mostly set at a fixed interval. This fixed interval is insufficient to straighten the metal wire. When the metal wire has significant bending or high material hardness, the fixed-interval straightening rollers cannot provide enough corrective force, easily resulting in residual slight bending after straightening. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a straightening device for a continuous annealing rewinding machine. This device solves the technical problem that most current straightening devices are set with a fixed spacing, which can only straighten the metal wire by relying on the fixed spacing. When the metal wire has obvious bending or high material hardness, the straightening rollers with a fixed spacing cannot provide sufficient straightening force.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a straightening device for a continuous annealing and rewinding machine is designed, including a base, a screw is rotatably connected to the top of the base, a lifting block is threaded through the surface of the screw, the lifting block is threadedly connected to the screw, an inclined rod is rotatably connected to the side wall of the lifting block, a first insertion post is fixedly connected to the lower side wall of the inclined rod and the side wall of the base directly below, and a first straightening roller is rotatably connected to the surface of the first insertion post.

[0006] In this solution, by setting an inclined bar at the top of the base, the traction force and friction of the metal wire during its movement drive the first straightening roller above to naturally press down, forming a compensating squeezing effect. Furthermore, the pressure can be adaptively adjusted according to the degree of bending of the metal wire, resulting in a more significant straightening effect on metal wires with obvious bending or high hardness. Compared with a straightening structure with fixed spacing, this solution effectively improves the straightening accuracy and stability.

[0007] Preferably, the side wall of the base is provided with a plurality of equidistant vertical grooves, and a one-way lead screw is rotatably connected to the inner side of the vertical groove. A threaded sleeve passes through the surface of the one-way lead screw, and the threaded sleeve is threadedly connected to the one-way lead screw. A support frame is fixedly connected to the side wall of the threaded sleeve.

[0008] In practical applications, when straightening rollers of different diameters are replaced, the height of the metal wire will also change. By rotating the screw block at the top of the one-way screw, the threaded sleeve can be driven to rise and fall along the vertical groove, thereby driving the support frame and the No. 2 straightening roller above to adjust to the height that matches the path of the metal wire.

[0009] Preferably, a fixing ring is fixedly connected to the top of the support frame, and the surface of the fixing ring is provided with a plurality of bolt holes in a circumferential array. A support rod is snapped into the inner wall of the fixing ring, and two fixing bolts are threaded to one end of the support rod.

[0010] In practical applications, the support rod is rotated to a preset angle within the fixed ring, and then locked by bolts passing through the corresponding bolt holes. This multi-angle adjustment function allows the No. 2 straightening roller to apply straightening force to the metal wire from non-vertical and horizontal directions, further eliminating residual bending and improving the straightening effect.

[0011] Preferably, an adjustment frame is fixedly connected to the other end of the support rod, and a bidirectional lead screw is rotatably connected to the inner side of the adjustment frame. Two adjustment blocks pass through the surface of the bidirectional lead screw, and the adjustment blocks are threadedly connected to the bidirectional lead screw. A second insertion post is fixedly connected to the top of the adjustment block, and a second straightening roller is rotatably connected to the surface of the second insertion post.

[0012] In practical applications, when processing metal wires of different diameters, rotating the screw block of the bidirectional lead screw can cause the two adjusting blocks to drive the No. 2 straightening roller to move synchronously in opposite directions, precisely adjusting the distance between the two rollers. At the same time, the distance also needs to be adjusted when changing the No. 2 straightening roller of different diameters.

[0013] Preferably, the surfaces of the first and second inserts are provided with recessed threads, and the surfaces of the first and second inserts are threadedly connected with limit sleeves. The side of the limit sleeve that contacts the first and second straightening rollers is smoothly polished.

[0014] In practical applications, when installing the straightening roller, tighten the limiting sleeve along the threaded insert until it fits against both ends of the roller body. This can effectively limit the axial movement of the straightening roller when it rotates at high speed, and the smooth polished contact surface reduces the rotational resistance of the roller body.

[0015] Preferably, a counterweight is fixedly connected to the upper side wall of the inclined rod, and the surface of the lifting block is provided with a protrusion to prevent the inclined rod from rotating clockwise.

[0016] In practical applications, the counterweight keeps the inclined bar in an inclined state, and the protrusion prevents the inclined bar from lifting up the No. 1 straightening roller above it, thus preventing it from losing its straightening ability.

[0017] Preferably, a limiting rod is fixedly connected to the top of the base on one side of the screw, and the limiting rod passes through the surface of the lifting block and is slidably connected to the lifting block.

[0018] In practical applications, when adjusting the height of the lifting block by rotating the screw, the limit rod restricts the lifting block from rotating synchronously with the screw, ensuring that it moves smoothly only in the vertical direction.

[0019] Preferably, the top end of the unidirectional lead screw penetrates the inner wall of the vertical groove, one end of the bidirectional lead screw penetrates the inner wall of the adjustment frame, and both the top end of the unidirectional lead screw and the end of the bidirectional lead screw located outside the adjustment frame are fixedly connected to a screw block.

[0020] In practical applications, operators can adjust the height and spacing by manually rotating the screw block without the need for tools such as wrenches, thus improving the ease of operation.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model uses a slanted bar at the top of the base to drive the first straightening roller above to press down naturally by using the traction and friction of the metal wire during its movement, thus creating a compensating squeezing effect. It can also adaptively adjust the pressure according to the degree of bending of the metal wire, and the straightening effect is more significant for metal wires with obvious bending or high hardness. Compared with a straightening structure with fixed spacing, it effectively improves the straightening accuracy and stability.

[0023] 2. This utility model, by setting a support frame and a fixing ring on the side wall of the base, allows the adjustment frame to be fixed at any position on the fixing ring via the support rod. This enables the No. 2 straightening roller to break through the limitations of traditional vertical or horizontal straightening and achieve angle adjustment in any direction. At the same time, the linear arrangement design of multiple sets of No. 2 straightening rollers can progressively straighten the metal wire from multiple dimensions, further eliminating residual bending and greatly improving the adaptability and straightening effect of the device for metal wires of different specifications and bending shapes.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] Example 1: A straightening device for a continuous annealing rewinding machine, see [link to example]. Figures 1 to 4 The system includes a base 1, a screw 4 rotatably connected to the top of the base 1, a lifting block 3 penetrating the surface of the screw 4, the lifting block 3 being threadedly connected to the screw 4, a limit rod 401 fixedly connected to the top of the base 1 on one side of the screw 4, the limit rod 401 penetrating the surface of the lifting block 3 and slidingly connected to the lifting block 3; a diagonal rod 5 rotatably connected to the side wall of the lifting block 3, a counterweight 501 fixedly connected to the upper side wall of the diagonal rod 5, a protrusion 301 on the surface of the lifting block 3 to prevent the diagonal rod 5 from rotating clockwise, a first insertion post 6 fixedly connected to the lower side wall of the diagonal rod 5 and the side wall of the base 1 directly below, and a first straightening roller 2 rotatably connected to the surface of the first insertion post 6.

[0031] In the above technical solution, rotating the screw 4 causes the lifting block 3 to slide up and down along the limiting rod 401, thereby adjusting the distance between the upper and lower No. 1 straightening rollers 2. This is used when changing No. 1 straightening rollers 2 of different diameters, and the extrusion pressure can also be preset by adjusting the height. The counterweight 501 keeps the inclined rod 5 in an inclined state, while the protrusion 301 limits the inclined rod 5 to prevent it from tilting too much and to prevent clockwise rotation from causing the distance between the upper and lower No. 1 straightening rollers 2 to become too large, thus losing the straightening effect. When the metal wire passes between the two rollers, the traction force of the metal wire and the friction between them will drive the upper No. 1 straightening roller 2 to press down, that is, the inclined rod 5 rotates counterclockwise, forming a compensating extrusion effect. It can also adaptively adjust the pressure according to the degree of bending of the metal wire, and the straightening effect is more significant for metal wires with obvious bending or high hardness. Compared with the straightening structure with a fixed spacing, it effectively improves the straightening accuracy and stability, avoids insufficient straightening or wire damage caused by fixed pressure, and improves the straightening accuracy.

[0032] Specifically, such as Figure 2 and Figure 3As shown, the side wall of the base 1 has several equidistant vertical grooves 7. A one-way screw 8 is rotatably connected to the inner side of the vertical groove 7. A threaded sleeve 9 passes through the surface of the one-way screw 8. The threaded sleeve 9 is threadedly connected to the one-way screw 8, and a support frame 10 is fixedly connected to the side wall of the threaded sleeve 9. A fixing ring 11 is fixedly connected to the top of the support frame 10. Several bolt holes 111 are arranged in a circular array on the surface of the fixing ring 11. A support rod 12 is snapped into the inner wall of the fixing ring 11. Two fixing bolts 121 are threadedly connected to one end of the support rod 12.

[0033] In the above technical solution, rotating the screw block 19 of the unidirectional lead screw 8 causes the threaded sleeve 9 to drive the support frame 10 to rise and fall along the vertical groove 7, adjusting the height of the second straightening roller 17. The support rod 12 can rotate to any angle within the fixed ring 11 and is locked by the fixing bolt 121 passing through the corresponding bolt hole 111, realizing flexible switching of the straightening direction. This allows the second straightening roller 17 to break through the limitations of traditional vertical or horizontal straightening and achieve angle adjustment in any direction. Simultaneously, the linear arrangement of multiple sets of second straightening rollers 17 enables progressive straightening of the metal wire from multiple dimensions, further eliminating residual bending and significantly improving the adaptability and straightening effect of the device for metal wires of different specifications and bending shapes. It should be noted that the height adjustment of the support frame 10 is suitable for changing straightening rollers of different diameters, ensuring that the center of the fixed ring 11 is on the horizontal movement path of the metal wire.

[0034] Furthermore, such as Figure 4 As shown, an adjustment frame 13 is fixedly connected to the other end of the support rod 12. A bidirectional lead screw 14 is rotatably connected to the inner side of the adjustment frame 13. Two adjustment blocks 15 pass through the surface of the bidirectional lead screw 14. The adjustment blocks 15 are threadedly connected to the bidirectional lead screw 14, and the top of the adjustment blocks 15 is fixedly connected to the second insertion post 16. The surface of the second insertion post 16 is rotatably connected to the second straightening roller 17. When the screw block 19 of the bidirectional lead screw 14 is rotated, the two adjustment blocks 15 move synchronously in the opposite direction along the lead screw, causing the second straightening rollers 17 on the two second insertion posts 16 to move closer or further away from each other, so as to precisely adjust the distance between the two rollers to match the diameter of the metal wire. This is suitable for changing the second straightening roller 17 with different diameters.

[0035] It is worth noting that, such as Figure 4 As shown, both the first insertion post 6 and the second insertion post 16 have recessed thread lines on their surfaces, and both the first insertion post 6 and the second insertion post 16 are threadedly connected to a limiting sleeve 18. The side of the limiting sleeve 18 that contacts the first straightening roller 2 and the second straightening roller 17 is smoothly ground. The limiting sleeve 18 is rotated along the thread of the insertion post to make it fit tightly against both ends of the straightening roller, restricting the axial movement of the straightening roller, effectively preventing the metal wire from running off-center due to the displacement of the straightening roller, and ensuring processing stability. The smooth contact surface reduces the frictional resistance when the straightening roller rotates, and avoids the vibration caused by friction from affecting the straightening accuracy.

[0036] It is worth noting that, such as Figure 2 and Figure 4 As shown, the top end of the unidirectional lead screw 8 penetrates the inner wall of the vertical groove 7, and one end of the bidirectional lead screw 14 penetrates the inner wall of the adjustment frame 13. Both the top end of the unidirectional lead screw 8 and the end of the bidirectional lead screw 14 located outside the adjustment frame 13 are fixedly connected to a screw block 19. By manually rotating the screw block 19, the unidirectional lead screw 8 or the bidirectional lead screw 14 can be directly driven to rotate. The height and spacing can be adjusted without additional tools, making the operation convenient.

[0037] It is worth noting that the No. 1 straightening roller 2 and the No. 2 straightening roller 17 can be replaced. The newly replaced straightening rollers will only differ in size in the straightening grooves on the annular surface and in diameter, while the width remains the same, thus ensuring that the center of the fixed ring 11 is always in the center of the metal wire's moving path.

[0038] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0039] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
