Description

Technical Field

[0001] The utility model belongs to the field of metal wire winding and unwinding equipment, and particularly relates to a wire winding and unwinding device. Background Art

[0002] After wire drawing, the metal wire should be wound in time and wound into a relatively regular coil at the back of the production line. After the number of coils gradually increases to a certain volume, it will be transferred away by a forklift and a new empty coil will be replaced.

[0003] The existing wire winding and unwinding devices need to ensure that they have sufficient support strength as the most basic condition. However, in addition, the problem is that the winding and unwinding diameters of many winding and unwinding devices are fixed and cannot be adjusted, resulting in a reduction in their actual utilization rate. Moreover, some wire winding and unwinding structures only have the function of winding or unwinding wires. For example, a wire unwinding mechanism of a wire drawing machine disclosed in Patent CN202222386358.5 removes the empty rotating rack on the turntable through a lifting tool, places a new rotating rack wound with raw material wire on the turntable, and under the pulling force of the subsequent wire drawing mechanism and winding mechanism, the raw material wire is pulled, thereby driving the turntable to rotate. And for some wires, although they can realize the functions of winding and unwinding, the wires are placed vertically, that is, their rolling surfaces face the ground, such as a wire winding and unwinding machine for a wire spool disclosed in Patent CN216836608U, which is not conducive to the transfer of wires. There are also some winding and unwinding devices that can also realize the functions of winding and unwinding, but they need to be operated manually, such as a manual wire winding and unwinding device disclosed in CN104743413A, which has poor practicability and will increase the working intensity of workers.

Detailed implementation manners

[0033] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. For the convenience of description, the words such as "upper", "lower", "left" and "right" hereinafter only indicate the same directions as the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

[0034] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0035] Examples, such as Figures 1 to 13 As shown, a wire winding and unwinding device provided by the present utility model includes a chassis 1. A central support member 2 is provided at the center of the chassis 1. A rotary center assembly 3 that is rotationally engaged with the central support member 2 is provided in the central support member 2. A wire winding and unwinding support bracket 4 is provided on the rotary center assembly 3. Among them, the chassis 1 not only serves as the support basis for the central support member 2, the rotary center assembly 3, and the wire winding and unwinding support bracket 4, but also can serve as a pallet for a forklift. The chassis 1 together with other structures and the wire reel can be transferred manually by the forklift to make room for the wire winding and unwinding of the next wire reel. It should be noted that the forklift can also directly fork the wire reel from the chassis 1 without moving other structures. On this basis, the rotary center assembly 3 provided by the present utility model includes a central shaft 31. A bearing 32 is provided at the top of the central shaft 31. A bearing seat 33 is provided outside the bearing 32. A belt groove 34 for driving and connecting a V-belt is provided on the outer side surface of the bearing seat 33. A steel pipe mounting sleeve 35 that is synchronously connected to the bearing seat 33 is provided at the top of the bearing seat 33. Two axially distributed mounting hole groups 36 are provided on the side surface of the steel pipe mounting sleeve 35. Each mounting hole group 36 includes a plurality of mounting holes. The wire winding and unwinding support bracket 4 includes a plurality of support pipes 41 connected to the mounting holes. Reinforcing pipes 42 are provided at the ends of the support pipes 41 located on the same vertical axis plane. A horizontally adjustable wire supporting pipe 43 is provided on the support pipe 41 in the upper mounting hole. A joint hole for connecting the head end of the wire is provided on the wire supporting pipe 43.

[0036] Specifically, by adjusting the radial position of the support wire tube 43 on the support tube 41, the purpose of adjusting the winding and unwinding diameter of the wire coil can be achieved. Moreover, the winding and unwinding support 4 is supported by a double-layer support tube 41 and a reinforcing tube 42, with relatively high structural strength and good support effect, effectively improving the load-bearing capacity of the device. Therefore, when the wire on the wire winding and unwinding device is heavy, this design effectively prevents excessive bending of the distal end of the support tube 41. By using a bearing block 33 with a groove 34, not only can the function of rotational support be realized, but also a transmission relationship can be established with the V-belt and the reduction motor, facilitating motorized winding and unwinding. Therefore, for online automatic variable-speed winding, the V-belt should be installed at the groove 34 position of the bearing block 33, and 1 - 3 V-belts can be used. The other end of the used V-belt is connected to the reduction motor, one end of the reduction motor is connected to the power supply, and the other end is connected to the control device. This control device can be the control device of the wire drawing production line or exist independently. After setting the relevant parameters, when the wire drawing speed changes, the speed of the reduction motor changes, and the wire winding speed changes accordingly, thereby realizing the online control of the winding speed.

[0037] Furthermore, the central support member 2 and the rotation center assembly 3 have good rotational matching performance. For example, the central shaft 31 is nested with the central support member 2, and a bearing 32 and a bearing block 33 are sleeved on the central shaft 31. The steel pipe mounting sleeve 35 connected to the bearing block 33 provides an assembly node for the support tube 41, thus enabling the rotational support of the wire coil. Coupled with the support of the chassis 1, the winding and unwinding performance of the device carrying a wire coil with a relatively large volume can be effectively ensured. The design is reasonable, the structure is simple, the cost is low, the stability is good, and it is convenient for transportation.

[0038] To improve the support stability of the chassis 1, the chassis 1 provided by the present utility model includes four side tubes 11 connected end to end to form a square shape. At the bottom corner positions of the side tubes 11, there are bottom corner square tubes 12. Between the side tubes 11, there are intermediate square tubes 13 connected in a cross shape and forming a field shape with the side tubes 11. At the bottom of the intermediate square tubes 13, there are four reinforcing square tubes 14 connected end to end to form a square shape, and the connection nodes of adjacent reinforcing square tubes 14 are located on the bottom surface of the intermediate square tubes 13. Among them, the side tubes 11 and the intermediate square tubes 13 form a field-shaped support surface, which can bear the overall pressure of the wire and the winding and unwinding support 4, and transfer the pressure of the wire winding and unwinding device downward. When the chassis 1 is under great pressure during forklift handling, the reinforcing square tubes 14 can serve as reinforcing ribs to ensure that the bottom bracket will not deform or break during forklift handling; on the one hand, the bottom corner square tubes 12 are used for support, and on the other hand, they can ensure a reasonable spacing for the forklift forks, enabling the forklift to carry the entire device.

[0039] In order to improve the supporting effect of the central support member 2, the central support member 2 provided by the present utility model includes a square plate 21. The square plate 21 can be welded to the intermediate square pipe 13. A bushing 22 is provided at the top of the square plate 21, and a plurality of reinforcing ribs 23 are provided between the bushing 22 and the square plate 21. Among them, the bushing 22 provides a support hole and a support surface for the central shaft 31, and the square plate 21 can disperse the pressure exerted on the central support member 2 from top to bottom to the chassis 1, and forms a reinforcing structure with the reinforcing ribs 23 to ensure that the central support member 2 has a large anti-deformation ability.

[0040] In order to ensure the supporting effect of the central shaft 31 on the bearing 32 and the bearing seat 33, the present utility model is provided with a plurality of radial threaded holes 24 on the side surface of the bushing 22. Screws 25 for connecting the bushing 22 and the central shaft 31 are arranged in the radial threaded holes 24. The working position of the central shaft 31 can be positioned by using the screws 25, and the bearing 32 and the bearing seat 33 can rotate reasonably at the top of the central shaft 31, and drive the steel pipe installation sleeve 35 and the bearing seat 33 to rotate synchronously.

[0041] Furthermore, the central shaft 31 provided by the present utility model is of a stepped structure and includes a first stepped surface and a second stepped surface. A first bearing 321 and a second bearing 322 are respectively arranged on the first stepped surface and the second stepped surface. The first bearing 321 and the second bearing 322 cooperate with the stepped holes 38 arranged inside the bearing seat 33. Among them, the first bearing 321 must be able to bear a large axial load and a small radial load; when selecting the second bearing 322, a bearing that can bear axial and radial loads with numerically close values can be selected, or a bearing that can bear a large radial load can be selected.

[0042] In order to realize the synchronous rotation of the bearing seat 33 and the steel pipe installation sleeve 35, the present utility model is provided with pin holes 37 on the opposite surfaces of the bearing seat 33 and the steel pipe installation sleeve 35. The pin holes 37 are used to install pins. Four pin holes 37 can be provided and are symmetrically distributed in pairs. As for the depth of the pin holes 37 and the length of the pins, they can be selected according to actual needs to ensure that the steel pipe installation sleeve 35 will not be disengaged from the bearing seat 33 randomly.

[0043] For the convenience of installing the support pipe 41, in the present utility model, the end of the support pipe 41 is inserted into the installation hole. An auxiliary installation member 44 is provided at a position of the support pipe 41 close to the installation hole. After the auxiliary installation member 44 is fixed to the support pipe 41, the actual mating area between the support pipe 41 and the steel pipe support sleeve 35 can be increased. Specifically, the auxiliary installation member 44 provided by the present utility model includes a sleeve 441 nested with the support pipe 41. An arc-shaped blocking piece 442 is provided at the end of the sleeve 441. The arc-shaped surface of the arc-shaped blocking piece 442 contacts the cylindrical surface of the steel pipe installation sleeve 35. The sleeve 441 is connected and fixed to the support pipe 41 by using common connecting parts, or can also be welded. While the end of the support pipe 41 is inserted into the installation hole, the arc-shaped surface of the arc-shaped blocking piece 442 effectively contacts the steel pipe installation sleeve 35, thereby providing arc-shaped surface support for the support pipe 41, increasing the pressure-bearing direction of the support pipe 41 and improving its compressive capacity.

[0044] For the convenience of adjusting the cable support pipe 43, the cable support pipe 43 provided by the present utility model includes a vertical section 431. A horizontal section 432 is provided at the bottom of the vertical section 431. The horizontal section 432 is in sliding sleeve fit with the support pipe 41. A positioning hole is provided at the bottom of the horizontal section 432. A positioning screw 45 for connecting the horizontal section 432 and the support pipe 41 is provided in the positioning hole. Among them, the vertical section 431 is used to provide inner diameter support for the wire. The relative position between the horizontal section 432 and the support pipe 41 reflects the inner diameter of the wire. If the positioning screw 45 is used for positioning, the included angle between the axis of the positioning hole and the horizontal plane is 10° - 50°, aiming to prevent the wire from winding onto the positioning screw 45 and affecting the quality of the wire coil.

[0045] To ensure the use effect of the steel pipe installation sleeve 35, a sleeve cover 39 is provided at the top of the steel pipe installation sleeve 35, which is used to block the hollow part of the steel pipe installation sleeve 35 to prevent dust and metal particles from entering the bearing 32 and the rotating support surface of the central shaft 31.

[0046] The above is only the preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
