Description

Technical Field

[0001] The present invention relates to the technical field of wire cutting machine tools, and particularly relates to a wire coil processing lathe and a usage method thereof. Background Art

[0002] A wire refers to a conductor for transmitting electric energy, which is divided into bare wires, electromagnetic wires, and insulated wires. Bare wires have no insulation layer and include copper and aluminum flat wires, overhead stranded wires, and various profiles, such as shaped wires, bus bars, copper bars, aluminum bars, etc. The coil processing of wires usually requires a machine tool to wind the coil into a roll, and then cut the wire at a fixed point to form a coil roll, which is convenient for storage and transportation by manufacturers and distributors.

[0003] Application No. CN202122330845.5 discloses the technical field of wire cutting machine tools, specifically a wire cutting machine tool for coil production that is convenient for fixing workpieces, including a wire cutting machine tool body. A placement base is installed on the wire cutting machine tool body, and a mounting frame is fixedly connected to the placement base. A fixing structure is provided on the mounting frame. The fixing structure includes a sliding block. A sliding block is slidably connected to the mounting frame. An installation cover is fixedly connected to the sliding block. Four movable plates are slidably connected to the installation cover. A fixing frame is fixedly connected to the movable plate. The fixing frame is slidably connected to the installation cover. A first spring is wound around the fixing frame. An adjustment structure and a driving structure are provided on the sliding block. A regulation structure is provided on the mounting frame; when fixing or releasing the fixation of the metal ring, it is not necessary to adjust multiple times, the operation is simple and fast, and the operation difficulty of the staff is reduced.

[0004] Currently, all wire coil processing machine tools adopt the conventional winding method from the inside to the outside. However, when winding from the inside to the outside, during the process of winding from the inner circle to the outer circle, the winding speed, the winding position of the wire, and the tightness of the cooperation between components are all related to the tightness of the coil. If any one of them deviates, it will cause the problem of wire coil relaxation, resulting in increased difficulty in bundling and wrapping in the later stage or even rework. For this reason, we propose a wire coil processing lathe and a usage method thereof. Summary of the Invention

[0006] The basic scheme of the present invention is: a wire coil processing lathe, including a frame, a rotating base is installed on the frame, and a wire cutting head for processing the wire is installed on the frame, and also includes multiple groups of coil processing supporting mechanisms, the coil processing supporting mechanisms are distributed on the surface of the base in a ring shape with the midpoint of the base as the center of the circle, the coil processing supporting mechanisms carry the coils wound into rolls of wires, each group of the coil processing supporting mechanisms includes a coil supporting plate, a protrusion is integrally installed on one end of the coil supporting plate close to the center of the wire coil, a coil winding rod is installed on the top of the protrusion, the axis of the coil winding rod is parallel to the axis of the base, and multiple coil winding rods arranged in a ring facilitate the winding of the wire coil, and a linkage contact plate is integrally connected to the top of the coil winding rod, and there is a certain angle between the linkage contact plate and the coil winding rod, and a through groove is opened on the inner side of the coil winding rod.

[0007] Preferably, a sliding limit mechanism cooperating with the coil processing bearing mechanism is installed on the side wall of the base, and the sliding limit mechanism is used to limit the angle of the coil bearing plate in the initial stage of the wire coil winding. The sliding limit mechanism includes a movable limit plate that moves along the radial direction of the base, and a gasket is installed on the inner wall of the movable limit plate. The bottom of the movable limit plate is integrally connected with a pad, and the top wall of the pad is used to resist the end of the coil bearing plate to prevent the coil bearing plate from reversing in the initial stage of the wire coil winding. The movable limit plate is driven by an elastic member.

[0008] Preferably, guide pillars are symmetrically and integrally installed on both sides of the movable limit plate, and the guide pillars are inserted on the inner side of the base. The elastic member is specifically an expansion spring, which is sleeved on the outer side of the guide pillars and is used to push the movable limit plate to move toward the center position of the base. The first end of the expansion spring is fixedly connected to the guide pillars, and the second end of the expansion spring is fixedly connected to the inner wall of the base.

[0009] Preferably, a plurality of wire coil inner side tensioning structures are rotatably connected to the inner side of the middle columnar member, and the wire coil inner side tensioning structures are used to link with the coil bearing plate and tension the wire coils, and the wire coil inner side tensioning structures include a driven linkage plate and a tensioning member, and the driven linkage plate and the tensioning member are an integrated structure, and a groove cooperating with the wire coil inner side tensioning structure is opened on the inner side of the middle columnar member.

[0010] Preferably, the tensioning member includes a connecting plate and a contact plate, the angle between the connecting plate and the contact plate is between 130-160 degrees, the connecting plate is used to connect the driven linkage plate and the contact plate, and the contact plate contacts the inner wall of the wire coil after flipping.

[0011] Preferably, a spring for resetting is installed on the bottom wall of the coil bearing plate close to the end of the sliding limiting mechanism.

[0012] Preferably, the angle between the linkage contact plate and the coil winding rod is a right angle.

[0013] Preferably, the coil carrier plate is rotatably connected to the base via a rotating member, and the protrusion is installed at a position at the bottom of the coil carrier plate close to the inner circle of the wire coil.

[0014] Preferably, the base is driven by a machine tool drive unit, which includes a drive motor, a synchronous wheel 1, a synchronous wheel 2 and a synchronous belt. The drive motor is installed on the inner side of the frame, and the axis of the drive motor is parallel to the axis of the base. The synchronous wheel 1 is installed at the output end of the drive motor, and the synchronous wheel 2 is installed at the bottom of the base. The synchronous wheel 1 and the synchronous wheel 2 are connected by a synchronous belt transmission.

[0015] Preferably, a method for using a wire coil processing lathe is characterized by comprising the following steps:

[0016] A. The end of the wire is fixed to any coil winding rod, and the base is driven by a driving motor to rotate so that the wire is wound in a ring shape on the surface of the coil winding rod and the diameter of the coil gradually increases;

[0017] B. When the diameter of the wire coil increases and the outer wall of the wire coil contacts, as the diameter of the wire coil continues to increase, the movable limit plate is pushed so that the movable limit plate moves outward along the radial direction of the base until the pad at the bottom of the movable limit plate no longer contacts the coil bearing plate;

[0018] C. When there is space near the lower end of the sliding limit mechanism, the weight of the wire coil is increasing and the position of the rotating part is close to the center, so the coil carrier plate is pressed down, causing the end of the coil carrier plate close to the center of the base to tilt up. After the coil is tilted up, the coil winding rod drives the linkage resistance plate to move the driven linkage plate, so that the angles of the driven linkage plate and the tensioning member change;

[0019] D. When the tensioning piece rotates, it passes through the through slot inside the coil winding rod. After the rotation, the contact plate of the tensioning piece squeezes and tensions the inner wall of the wire coil. The heavier the weight of the wire coil, the better the tensioning effect. Then, the wire cutting head is used to cut the wire.

[0020] E. When the wire coil is removed from the base, the weight on the coil carrier plate decreases, and the coil carrier plate is reset under the action of the spring. The tensioning piece is reset and drooped under the action of gravity, and the angle of the resistance plate changes after reset, which facilitates the removal of the coil.

[0021] The working principle and advantages of the present invention are:

[0022] 1. The coil processing bearing mechanism is linked to the winding of the wire coil. The weight and diameter of the coil are gradually increased, so that the coil bearing plate of the coil processing bearing mechanism is reversed, so that the end of the coil bearing plate close to the inner circle of the coil is tilted, and the inner side of the wire coil is tensioned from the inside of the coil to increase the tightness of the wire coil, that is, to tighten the coil. Such a coil is not easy to loosen, which is convenient for subsequent bundling, packaging and handling.

[0023] 2. As the diameter of the coil gradually increases, it will interfere with the movable limit plate and cause it to move outward. During the movement, a distance gradually appears between the pad and the coil carrier plate. When the pad and the coil carrier plate are no longer in contact, the coil carrier plate can be flipped over to ensure the flatness of the bottom end surface of the coil during the early winding process of the wire coil.

[0024] 3. The coil winding rod is driven by the tilting of the coil bearing plate to move the driven linkage plate, thereby tilting the tensioning member. The contact plate of the tilted tensioning member is attached to and tensioned against the inner wall of the wire coil, thereby fully tensioning the wire coil without affecting the winding of the coil. At the same time, the above operations do not require the separate setting of dedicated driving components, thereby reducing the use and maintenance costs of the machine tool.

DETAILED DESCRIPTION

[0033] The following is a further detailed description through specific implementation methods:

[0034] like Figures 1 to 7 As shown, a wire coil processing lathe comprises a frame 1, a rotating base 301 is mounted on the frame 1, the base 301 is driven by a machine tool driving unit 2, the machine tool driving unit 2 comprises a driving motor 201, a synchronous wheel 1 202, a synchronous wheel 203 and a synchronous belt 204, the driving motor 201 is mounted on the inner side of the frame 1, and the axis of the driving motor 201 is parallel to the axis of the base 301, the synchronous wheel 1 202 is mounted on the output end of the driving motor 201, the synchronous wheel 203 is mounted on the bottom of the base 301, the synchronous wheel 1 202 and the synchronous wheel 2 203 are connected by a synchronous belt 204, and a wire cutting head 7 for processing wires is mounted on the frame 1;

[0035] This solution further includes multiple groups of coil processing and carrying mechanisms 4, a sliding limit mechanism 5 that cooperates with the coil processing and carrying mechanism 4, and an inner tensioning structure 6 for the wire coil. The coil processing and carrying mechanisms 4 are annularly distributed on the surface of the base 301 with the midpoint of the base 301 as the center of the circle. The coil processing and carrying mechanisms 4 carry the coils formed by winding the wire. Each group of coil processing and carrying mechanisms 4 includes a coil carrying plate 401. A spring for resetting is installed on the bottom wall of the coil carrying plate 401 near the end of the sliding limit mechanism 5. A convex block 402 is integrally installed at one end of the coil carrying plate 401 close to the center of the wire coil. A coil winding rod 403 is installed on the top of the convex block 402. The square coil winding rod 403 facilitates the initial winding operation of the coil. The axis of the coil winding rod 403 is parallel to the axis of the base 301. The multiple annularly arranged coil winding rods 403 facilitate the winding of the wire coil. A linkage contact plate 405 is integrally connected to the top of the coil winding rod 403. There is a certain angle between the linkage contact plate 405 and the coil winding rod 403. A through groove 404 is provided inside the coil winding rod 403. Through the coil processing and carrying mechanism 4 linked by the winding of the wire coil, as the weight and diameter of the coil gradually increase, the coil carrying plate 401 of the coil processing and carrying mechanism 4 is reversed, causing the end of the coil carrying plate 401 close to the inner circle of the coil to tilt up, tensioning the inside of the wire coil from the inside of the coil, increasing the tightness of the wire coil, that is, making the coil taut. Such a coil is not easily loosened, facilitating subsequent bundling, wrapping, and handling work.

[0036] Among them, a sliding limit mechanism 5 cooperating with the coil processing bearing mechanism 4 is installed on the side wall of the base 301, and the sliding limit mechanism 5 is used to limit the angle of the coil bearing plate 401 in the initial stage of the wire coil winding. The sliding limit mechanism 5 includes a movable limit plate 501 that moves along the radial direction of the base 301, and a gasket 502 is installed on the inner wall of the movable limit plate 501. The bottom of the movable limit plate 501 is integrally connected with a pad 504, and the top wall of the pad 504 is used to resist the end of the coil bearing plate 401 to prevent the coil bearing plate 401 from reversing in the initial stage of the wire coil winding. The movable limit plate 501 is driven by an elastic member, and guide pillars 5 are symmetrically and integrally installed on both sides of the movable limit plate 501. 03, the guide column 503 is inserted into the inner side of the base 301, and the elastic member is specifically an expansion spring 505, which is sleeved on the outer side of the guide column 503 and is used to push the movable limit plate 501 to move toward the center position of the base 301, and the first end of the expansion spring 505 is fixedly connected to the guide column 503, and the second end of the expansion spring 505 is fixedly connected to the inner wall of the base 301. The diameter of the coil gradually increases, which will conflict with the movable limit plate 501 and make the movable limit plate 501 move outward. While moving, a distance gradually appears between the pad 504 and the coil carrier plate 401. When the pad 504 and the coil carrier plate 401 are no longer in contact, the coil carrier plate 401 can be flipped.

[0037] The inner side of the middle columnar member 302 is rotatably connected to a plurality of inner side tensioning structures 6 of the wire coils. The inner side tensioning structures 6 of the wire coils are used to link with the coil supporting plate 401 and tension the wire coils. The inner side tensioning structures 6 of the wire coils include a driven linkage plate 601 and a tensioning member 602. The driven linkage plate 601 and the tensioning member 602 are an integrated structure. A groove cooperating with the inner side tensioning structure 6 of the wire coils is provided on the inner side of the middle columnar member 302.

[0038] Specifically, the tensioning member 602 includes a connecting plate 6021 and a contact plate 6022, and the angle between the connecting plate 6021 and the contact plate 6022 is 150 degrees. The connecting plate 6021 is used to connect the driven linkage plate 601 and the contact plate 6022. The contact plate 6022 contacts the inner wall of the wire coil after flipping. The coil winding rod 403 is driven by the tilting of the coil supporting plate 401 to move the driven linkage plate 601, thereby causing the tensioning member 602 to tilt. The contact plate 6022 of the tilted tensioning member 602 is in contact with and tensioned against the inner wall of the wire coil, thereby fully tensioning the wire coil.

[0039] The included angle between the linkage abutment plate 405 and the coil winding rod 403 is a right angle.

[0040] The coil carrier plate 401 is rotatably connected to the base 301 via a rotating member 406 , and the protrusion 402 is installed at a position at the bottom of the coil carrier plate 401 close to the inner circle of the wire coil.

[0041] The working process of this embodiment is as follows: the end of the wire is fixed to any one of the coil winding rods 403, and the base 301 is driven to rotate by the driving motor 201 to realize that the wire is wound in a ring shape on the surface of the coil winding rod 403 and the diameter of the coil gradually increases. When the diameter of the wire coil increases and the outer wall of the wire coil contacts, as the diameter of the wire coil continues to increase, the coil can be pressed down with the help of a tool to ensure the regularity of the coil. The diameter of the wire coil continues to increase, and the outer wall of the wire coil pushes the movable limiting plate 501, so that the movable limiting plate 501 moves outward along the radial direction of the base 301 until the pad 504 at the bottom of the movable limiting plate 501 no longer contacts the coil supporting plate 401. When the coil supporting plate 401 is close to the lower end of the sliding limiting mechanism 5 and there is space, the weight of the wire coil continues to increase and the position of the rotating part 406 is close to the center, so it will press down. The coil carrying plate 401 causes one end of the coil carrying plate 401 close to the center of the base 301 to tilt up, and the tilted coil winding rod 403 drives the linkage contact plate 405 to move the driven linkage plate 601, so that the angles of the driven linkage plate 601 and the tensioning member 602 change, and the tensioning member 602 rotates through the through groove 404 on the inner side of the coil winding rod 403. After rotation, the contact plate 6022 of the tensioning member 602 squeezes and tensions the inner wall of the wire coil, and the greater the weight of the wire coil, the better the tensioning effect, and then the wire cutting head 7 is used to cut the wire, and when the wire coil is removed from the base 301, the weight of the coil carrying plate 401 is reduced, and the coil carrying plate 401 is reset under the action of the spring, and the tensioning member 602 is reset and drooped under the action of gravity, and since the angle of the contact plate 6022 changes after being reset, the coil is convenient to take out.
