Description

Technical Field

[0001] This utility model belongs to the field of wire straightening technology, specifically, it relates to a metal wire conveying and straightening device. Background Technology

[0002] Metal wire refers to a linear material made of metal. It is commonly used in electrical transmission, building structures, and machinery manufacturing. Common metal wires include steel wire, copper wire, and aluminum wire. Metal wires are usually packaged and transported in rolls. Before being processed by machines, they need to be unrolled and straightened.

[0003] Generally, a wire straightening device has two rows of straightening rollers, each row with multiple straightening rollers spaced apart. After unwinding, the metal wire is guided between the two rows of straightening rollers by a guide frame, traction machine, and other equipment, thus achieving the straightening process. A typical wire straightening production line uses one straightening device, and the equipment is arranged in a straight line, requiring a considerable amount of space. In spaces with limited length, the straightening production line can be arranged in an L-shape, with two straightening devices arranged in an L-shape. A wire guide bogie is placed between the two devices, and the two straightening devices respectively perform coarse straightening (approximately straightening the metal wire) and fine straightening (accurately straightening the metal wire).

[0004] For straightening devices, the straightening wheel is mounted on the machine body via an axle. Since the position of the axle on the machine body is fixed, when dealing with metal wires of different diameters, the straightening wheel needs to be disassembled and replaced with a straightening wheel of the corresponding specification. This requires repeated disassembly and assembly of the straightening wheel when dealing with metal wires of different diameters, which is quite cumbersome. In addition, it is necessary to prepare a variety of straightening wheels of different specifications, which increases costs. Utility Model Content

[0005] To address the problem that the current straightening device requires disassembling and replacing the straightening wheels with corresponding specifications when working with metal wires of different diameters, which is cumbersome and necessitates repeated disassembly and reassembly, and also increases costs due to the need to prepare various straightening wheels of different specifications, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A metal wire conveying and straightening device includes a body and a support leg connected to the bottom of the body. An adjustment mechanism and a limiting mechanism are installed on the body. The adjustment mechanism includes a top block and a force-bearing block slidably disposed on the body. Two force-bearing blocks are provided and disposed on opposite sides of the top block. A support plate is connected to the top surface of the force-bearing block, and the top of the support plate is rotatably connected to the bottom of a straightening wheel. The top block and the force-bearing blocks have inclined surfaces in contact. The limiting mechanism is connected to the top block and includes a positioning rod. Multiple positioning holes are sequentially opened on the outer wall of the body, and the positioning rod is inserted into the positioning holes to limit the sliding of the top block.

[0007] According to the aforementioned metal wire conveying and straightening device, the adjusting mechanism further includes a cavity formed on one side of the outer wall of the machine body. A sliding hole is formed on the inner wall of the cavity. A first spring is connected to the inner wall of the sliding hole. A sliding rod is connected to the end of the first spring away from the inner wall of the sliding hole. The sliding rod is inserted into the sliding hole and connected to one side of the outer wall of the force-bearing block. The top block is slidably disposed in the cavity.

[0008] According to the aforementioned metal wire conveying and straightening device, the limiting mechanism further includes a fixing block fixedly connected to a connecting rod. The outer wall of the fixing block has a movable hole. The outer wall of the positioning rod is movably disposed on the inner wall of the movable hole. A second spring is connected to the outer wall of one end of the positioning rod. The end of the second spring away from the positioning rod is connected to the inner wall of the movable hole. A pull rod is connected to the outer wall of the end of the positioning rod connected to the second spring. The outer wall of the pull rod movably penetrates the inner wall of the movable hole. A connecting plate is connected to the outer wall of the pull rod. The upper outer wall of the connecting plate is movably disposed on the outer wall of the connecting rod.

[0009] According to the aforementioned metal wire conveying and straightening device, a movable groove is provided above the inner wall of the machine body cavity, the outer wall of the supporting connecting plate is movably disposed on the inner wall of the movable groove, and a connecting rod is connected to one end of the outer wall of the top block.

[0010] According to the aforementioned metal wire conveying and straightening device, multiple sliding rods are spaced apart on one side of the outer wall of the force-bearing block.

[0011] According to the aforementioned metal wire conveying and straightening device, multiple straightening wheels are spaced apart on the support plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention allows the top block to move by moving the connecting rod. The inclined surface of the top block then presses against the inclined surface of the force-bearing block, pushing the force-bearing block to move. As the force-bearing block moves, it drives the support plate and the straightening wheel to move, thereby adjusting the distance between the straightening wheels. When straightening metal wires of different specifications and sizes, there is no need to disassemble the straightening wheels; simply adjust the distance between them. This eliminates the need for multiple straightening wheels with different specifications, thus reducing the cost of the device.

[0014] This invention utilizes a method where pulling the connecting plate outwards moves the connecting rod, causing the positioning rod to move outwards and disengage from the inner wall of the positioning hole. Simultaneously, the second spring is compressed. Then, pulling the connecting plate moves the connecting rod, which in turn moves the top block to complete the adjustment operation. Afterwards, the second spring rebounds, pushing the positioning rod back to its original position and locking it against the inner wall of the positioning hole. This ensures that the straightening wheel is fixed after adjustment, preventing displacement during the straightening process and facilitating the operator's operation of adjusting the spacing between the straightening wheels.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 4 As shown, a metal wire conveying and straightening device includes a body 1 and a support leg 2 connected to the bottom of the body 1. An adjustment mechanism 31 and a limiting mechanism 32 are installed on the body 1.

[0024] The adjustment mechanism 31 includes a top block 314, a force-bearing block 313, and a cavity formed on one side of the outer wall of the machine body 1. Two force-bearing blocks 313 are provided on either side of the top block 314. A support plate 315 is connected to the top surface of each force-bearing block 313, and the top of the support plate 315 is rotatably connected to the bottom end of a straightening wheel 316. The top block 314 and the force-bearing block 313 have inclined surfaces in contact. A sliding hole is formed in the inner wall of the cavity, and a first spring 311 is connected to the inner wall of the sliding hole. A sliding rod 312 is connected to the end of the first spring 311 away from the inner wall of the sliding hole. The sliding rod 312 is inserted into the sliding hole and connected to one side of the outer wall of the force-bearing block 313. The top block 314 is slidably disposed within the cavity, so that both the top block 314 and the force-bearing block 313 are slidably disposed on the machine body 1.

[0025] The limiting mechanism 32 includes a positioning rod 322. Multiple positioning holes 326 are sequentially formed on the outer wall of the machine body 1. The positioning rod 322 is inserted into the positioning holes 326 to limit the sliding of the top block 314. Specifically, the limiting mechanism 32 also includes a fixing block 321 fixedly connected to the connecting rod 317. The outer wall of the fixing block 321 has a movable hole. The outer wall of the positioning rod 322 is movably disposed on the inner wall of the movable hole. A second spring 323 is connected to the outer wall of one end of the positioning rod 322. The end of the second spring 323 away from the positioning rod 322 is connected to the inner wall of the movable hole. A pull rod 324 is connected to the outer wall of the end of the positioning rod 322 connected to the second spring 323. The outer wall of the pull rod 324 movably penetrates the inner wall of the movable hole. A connecting plate 325 is connected to the outer wall of the pull rod 324. The upper outer wall of the connecting plate 325 is movably disposed on the outer wall of the connecting rod 317.

[0026] Furthermore, an movable groove 318 is provided on the upper part of the inner wall of the cavity of the body 1, the outer wall of the supporting connecting plate 315 is movably disposed on the inner wall of the movable groove 318, and a connecting rod 317 is connected to the outer wall of one end of the top block 314.

[0027] Furthermore, multiple slide bars 312 are spaced apart on one side of the outer wall of the force-bearing block 313, which can provide uniform support to the left and right sides of a single force-bearing block 313, thereby improving the stability of the moving support of the force-bearing block 313.

[0028] Furthermore, the straightening wheel 316 has multiple [features] spaced apart on the supporting connecting plate 315.

[0029] Furthermore, the outer wall of the positioning rod 322 is engaged with the inner wall of the positioning hole 326. There are several positioning holes 326, which are evenly and equidistantly distributed on the outer wall of the body 1, so that they can be adapted to various metal wires of different specifications and sizes.

[0030] Furthermore, the spacing between each positioning hole 326 is equal to the size of a metal wire, thus allowing precise control of the distance between the straightening wheels 316 on both sides, thereby enabling precise adaptation to metal wires of different sizes.

[0031] The implementation principle of the metal wire conveying and straightening device in this embodiment is as follows: When it is necessary to adjust the straightening wheel 316, firstly, the limiting mechanism 32 releases the limiting fixation of the connecting rod 317, and then the connecting rod 317 can be pulled to the right to move. As the connecting rod 317 moves, it can drive the top block 314 to move. At this time, the outer wall of the top block 314 can squeeze the force blocks 313 on both sides. The force blocks 313 that are squeezed will move to both sides. During the movement of the force blocks 313, the sliding rod 312 can be driven to move to both sides. At the same time, during the movement of the sliding rod 312, the first spring is subjected to pressure. When the spring 311 applies a compression action, the force block 313 can drive the top support plate 315 to move. The movement of the support plate 315 can drive the straightening wheel 316 to move, thereby adjusting the distance between the straightening wheels 316 on both sides. This allows for the adaptation to metal wires of different specifications and sizes. When straightening metal wires of different specifications and sizes, there is no need to disassemble the straightening wheels 316. It is only necessary to directly adjust the distance between the straightening wheels 316. This eliminates the need to prepare multiple straightening wheels 316 with different specifications of gears, thereby reducing the cost of the device.

[0032] When adjustment and unlocking are required, first pull the connecting plate 325 outward, causing the connecting plate 325 to move the pull rod 324 and the positioning rod 322 outward. At the same time, during the movement of the positioning rod 322, it will compress the second spring 323, and the outer wall of the positioning rod 322 will disengage from the inner wall of the positioning hole 326 opened on the outer wall of the machine body 1, thus completing the unlocking. As the connecting plate 325 is pulled, it will move the connecting rod 317 to adjust the straightening wheel 316. After adjusting to the appropriate size, the pull rod 324 can be released. The rebound of the second spring 323 will drive the positioning rod 322 to reset and insert into the positioning hole 326 to complete the positioning. This ensures that the straightening wheel 316 can be limited and fixed after adjustment, preventing displacement during the straightening process, and facilitating the operation of adjusting the spacing of the straightening wheel 316 by the staff.

[0033] This invention is applicable to the straightening of thick metal wires. Within the allowable diameter range of the metal wire, the straightening rollers do not need to be replaced. By selecting a first spring with a larger elastic coefficient, the wobbling of the top block 314 can be reduced, ensuring that the straightening accuracy is within the allowable range. When straightening metal wires of different specifications and sizes, there is no need to disassemble the straightening rollers; simply adjust the distance between them. This eliminates the need to prepare multiple straightening rollers with different gear specifications, thereby reducing the cost of the device.
