Description

Technical Field

[0001] This invention relates to the field of cable processing technology, specifically to a wire tipping machine capable of adjusting the tip diameter and tip angle. Background Technology

[0002] Cable processing refers to the production process of performing a series of professional treatments on basic materials such as metal conductors or optical fibers according to the needs of different application scenarios. This includes, but is not limited to, conductor drawing, stranding, insulation layer coating, shielding layer braiding, sheath extrusion, as well as subsequent cutting, terminal crimping, and testing steps. Ultimately, the basic wire material is transformed into cable products with specific electrical, mechanical, and protective properties, which are widely used in power transmission, communication networks, industrial control, transportation, and many other fields.

[0003] In some cable processing scenarios, especially in the production of cables using steel wire as a reinforcing core or conductor, the high hardness and strength of the steel wire itself makes subsequent threading, stranding, or connection with other components difficult. This not only easily leads to problems such as jamming and wire breakage, but also affects processing efficiency and the quality stability of cable products. However, a steel wire tipping machine can use a specific mechanical structure to roll the ends of the steel wire, processing them into a gradually tapered or pointed structure. The steel wire ends treated in this way are easier to pass through molds, guide devices, or to cooperate with other connectors, effectively solving the problem of threading steel wire during processing. Traditional tipping mills mostly use a fixed groove specification roll design, which can only adapt to a single or very narrow range of steel wire diameters. If steel wires of different diameters need to be processed, the entire roll assembly with the corresponding groove must be disassembled and replaced. This is not only time-consuming and labor-intensive, resulting in long downtime, but also prone to roll alignment deviation due to repeated disassembly and assembly, reducing tipping accuracy. Furthermore, the adjustment method is limited. Traditional equipment often lacks a dedicated angle adjustment mechanism or relies on a simple rotating shaft for rough adjustment. Without visual references such as angle scales, the adjustment accuracy depends entirely on the operator's experience, which can easily lead to angle deviations based on "gut feeling". Summary of the Invention

[0004] The present invention addresses the problem that existing technical solutions are too limited, and provides a wire tipping machine that can adjust the tip diameter and tip angle. This solves the problem mentioned in the background that existing tipping machines can only be used for a certain range of wires, and that when tipping wires with large diameter differences, different types of rolls need to be replaced, which is time-consuming and labor-intensive.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A wire tipping machine capable of adjusting the tip diameter and tip angle includes a fixed base, a tipping frame, and a movable frame.

[0006] The fixed base is located above the mobile frame and serves as a basic support component. It has an internal rotating connection that is compatible with the rolling mill frame.

[0007] The tipping frame is located inside the fixed base and integrates the core tipping components. The upper and lower rolls are rotatably connected inside the tipping frame and are used to tip the steel wire. A roll adjustment and drive assembly is set at one end inside the tipping frame to adjust the distance between the upper and lower rolls and drive the upper and lower rolls to rotate relative to each other. Movable retaining rings are set outside the upper and lower rolls. The groove distance is adjusted by sliding within the grooves on the surfaces of the upper and lower rolls to control the tipping diameter of the steel wire.

[0008] Furthermore, a worm gear is rotatably connected inside the fixed base, and a worm wheel meshes above the worm gear. The worm wheel is installed at the bottom of the rolling mill frame. The rolling mill frame is rotatably connected to the corresponding position on the surface of the fixed base via a shaft passing through the center of the worm wheel. An angle indicator is provided on one side of the outer wall of the fixed base.

[0009] Furthermore, the angle indicator includes an angle scale and a pointer for displaying angle graduations. The angle scale is fixedly connected to the shaft at one end of the worm gear, and the angle scale is rotatably connected to the outer wall of the fixed base. The pointer is fixed above the angle scale and is relatively fixed to the outer wall of the fixed base.

[0010] Furthermore, the upper and lower rolls are distributed vertically, and the outer walls of the upper and lower rolls are provided with a number of slots circumferentially at equal intervals. The width of the slots gradually decreases from the outside to the inside along the radial direction of the roll. Multiple movable retaining rings are provided, which are distributed one-to-one along the slots. The movable retaining rings are sleeved on their corresponding slots and can slide along the length of the slot. The movable retaining rings and the fixed sidewall at the other end form a relative motion.

[0011] Furthermore, a positioning shaft is fixed inside the upper roller, and a sliding sleeve is fitted on the outer wall of the positioning shaft. The outer wall of the sliding sleeve is fixedly connected with a set of push rods in a ring array. The number of push rod sets corresponds one-to-one with the number of slots where the movable retaining ring is located. Adjacent push rod sets are fixedly connected by connecting rods.

[0012] Furthermore, a cylinder is fixed to one side of the outer wall of the mounting frame of the upper roll, and the sliding sleeve is fitted at the corresponding end of the cylinder. An extension rod is provided at the center of the shaft. The extension rod passes through the corresponding side of the mounting frame of the upper roll and is rotatably connected to the power output end of the cylinder. At the same time, the inner diameter of the rotating shaft at one end of the upper roll used to connect with the mounting frame and the inner diameter of the bearing adapted on the mounting frame are both larger than the outer diameter of the extension rod. The internal structure of the lower roll is the same as the internal structure of the upper roll.

[0013] Furthermore, the end of each movable retaining ring facing the top rod assembly is fixedly connected to one end of the corresponding top rod assembly. On the outer wall of the upper and lower rolls, at the interval between two adjacent slots, shaft holes for the extension and retraction of the top rod assembly are provided. The shaft holes penetrate the interior of the interval along the radial direction of the roll. The top rod assembly is driven by a cylinder to slide the sliding sleeve axially along the outer wall of the positioning shaft. Under the drive of the top rod assembly, the movable retaining ring can slide along the length direction of the corresponding slots of the upper and lower rolls.

[0014] Furthermore, the roll adjustment and drive assembly includes an upper drive bevel gear, a lower drive bevel gear, a driving bevel gear, a driven bevel gear, and a screw. The upper drive bevel gear and the lower drive bevel gear are coaxially arranged through a sliding cooperating shaft. The driving bevel gear and the driven bevel gear are distributed vertically. The driving bevel gear is fixedly connected to the center point of the upper roll body at the corresponding end through a shaft passing through its center. The driven bevel gear is fixedly connected to the center point of the lower roll body at the corresponding end through a shaft passing through its center.

[0015] Furthermore, a hollow shaft is fixed at the center of the upper transmission bevel gear, and the upper transmission bevel gear is assembled and connected to the bearing set at the corresponding position of the mounting frame where the upper roll is located through the hollow shaft. The sliding cooperative shaft passes through the hollow shaft, and the outer wall of the sliding cooperative shaft has raised strip-shaped structures symmetrically distributed along the center point. The inner wall of the hollow shaft has a slot adapted to the strip-shaped structure. The strip-shaped structure and the slot are embedded and engaged to realize synchronous rotation and axial relative sliding between the sliding cooperative shaft and the hollow shaft.

[0016] Furthermore, the top of the rolling mill frame is provided with a threaded groove for threaded connection with the screw, and the shaft head at the bottom of the screw passes through the threaded groove and is rotatably connected to the top of the mounting frame where the upper roll is located.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This equipment, on the one hand, utilizes the threaded engagement between the screw and the rolling pin frame to drive the upper roll to rise and fall smoothly, precisely adjust the distance between it and the lower roll, and quickly adapt to steel wires of different diameters. On the other hand, the engaging structure between the groove on the inner wall of the hollow shaft and the strip-shaped structure on the outer wall of the sliding coordinating shaft not only enables the two to rotate synchronously to stably transmit power and ensure that the upper and lower rolls always maintain a relative rotational state, but also allows the hollow shaft to slide axially along the sliding coordinating shaft with the upper roll mounting frame. While ensuring the distance adjustment, it also ensures the power for subsequent relative rotation. It can adapt to multiple specifications of steel wires without disassembling parts, which not only improves the adjustment efficiency but also ensures the power stability of the rolling pin processing, solving the problem of poor adaptability of traditional equipment.

[0018] 2. Traditional equipment struggles to simultaneously achieve precise adjustments to both the tip angle and diameter, requiring frequent roll assembly replacements. This new equipment, however, employs a worm gear drive system combined with an angle indicator for visual adjustment, making operation simple and convenient. Additional fastening bolts provide rigid locking after angle adjustment, effectively preventing angle deviation and ensuring stability during subsequent tipping. Unlike traditional fixed roll structures, this equipment utilizes a cylinder-driven synchronous linkage mechanism. The sliding sleeve, driven by the cylinder, pushes the top rod assembly, causing all movable retaining rings to slide synchronously along the roll groove. Combined with the progressively wider-inner-narrower groove structure, it precisely changes the effective groove width to control the tip diameter while preventing sudden increases in localized stress and breakage of the steel wire. This structure allows for flexible adjustment of the tip angle and diameter based on the specifications of the cable conductor wire and joint forming requirements, completely overcoming the limitations of traditional equipment and significantly improving the precision and adaptability of tipping processing.

[0019] 3. The connection method of the core components of this equipment provides reliable structural support for related adjustment components and lays the necessary foundation. On the one hand, the cylinder and the sliding sleeve are rotatably connected by an extension rod. At the same time, the inner diameter of the upper roll shaft and the corresponding bearing is larger than the outer diameter of the extension rod. This connection ensures that the cylinder remains fixed when the roll rotates, avoiding air pipe entanglement and power source instability. It also stably transmits the cylinder driving force through the extension rod, pushing the sliding sleeve to drive the movable retaining ring to accurately adjust the slot width, ensuring that the moving parts do not interfere with each other. On the other hand, the hollow shaft and the sliding cooperating shaft are connected by an embedded snap-fit ​​connection. The slot on the inner wall of the hollow shaft and the strip structure on the outer wall of the sliding cooperating shaft are precisely snapped together. This connection ensures that the two rotate synchronously to stably transmit power and ensure the continuous rotation of the roll. It also allows the hollow shaft to slide along the axial direction of the sliding cooperating shaft to meet the requirements of the upper roll lifting and adjusting the distance. After the height is adjusted, it also ensures the continuous relative rotation of the upper and lower rolls, providing a continuous and stable power foundation for the subsequent precise control of the tip diameter.

[0023] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Please refer to the appendix carefully. Figure 1-5 A wire tipping machine capable of adjusting the tip diameter and tip angle includes a fixed base 1, a tipping frame 2, and a movable frame 3.

[0026] The fixed base 1 is located above the mobile frame 3 and serves as a basic support component. It has a rotating connection inside that is compatible with the rolling pin frame 2.

[0027] The tipping frame 2 is located inside the fixed base 1 and integrates the core tipping components. The upper roll 4 and the lower roll 5 are rotatably connected inside the tipping frame 2 and are used to tip the steel wire. A roll adjustment and drive assembly 6 is provided at one end inside the tipping frame 2 to adjust the distance between the upper roll 4 and the lower roll 5 and drive the upper roll 4 and the lower roll 5 to rotate relative to each other. A movable retaining ring 7 is provided outside the upper roll 4 and the lower roll 5. The groove spacing is adjusted by sliding within the groove on the surface of the upper roll 4 and the lower roll 5 to control the tipping diameter of the steel wire.

[0028] In this embodiment, as Figure 2As shown, a worm gear 101 is rotatably connected inside the fixed base 1, and a worm wheel 102 is meshed above the worm gear 101. The worm wheel 102 is installed at the bottom of the rolling mill frame 2. The rolling mill frame 2 is rotatably connected to the corresponding position on the surface of the fixed base 1 through a shaft passing through the axis of the worm wheel 102. An angle indicator 103 is provided on one side of the outer wall of the fixed base 1.

[0029] With the above structure, a fastening bolt is provided on one side of the fixed base 1. The fastening bolt passes through the fixed base 1 and is threaded to one side of the rolling tip 2. It can be locked and fixed when the angle of the rolling tip 2 is determined, so as to ensure the stability of the angle during the rolling process. The fixed base 1 is provided with a structure for adjusting the angle of the rolling tip 2. When the rolling tip 2 is driven to rotate around the central shaft through the meshing transmission of the worm gear 102 and the worm 101, the rolling tip 2 will drive its internal rolling roll mechanism to deflect synchronously. The channel between the upper rolling roll 4 and the lower rolling roll 5 for rolling steel wire will also change angle. However, the overall path of the front steel wire guide, i.e., the feeding steel wire, is usually relatively fixed and smooth. Therefore, by adjusting the angle of the rolling tip 2, the angle of the rolling tip of the steel wire will change.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the angle indicator 103 includes an angle scale and a pointer for displaying angle scales. The angle scale is fixedly connected to the shaft at one end of the worm gear 102, and the angle scale is rotatably connected to the outer wall of the fixed base 1. The pointer is fixed above the angle scale and is fixed relative to the outer wall of the fixed base 1.

[0031] With the above structure, the angle scale is fixedly connected to the shaft at one end of the worm gear 102, so that the scale can rotate synchronously with the worm gear 102. It cooperates with the pointer that is fixed relative to the outer wall of the fixed base 1, allowing the operator to intuitively read the real-time deflection angle of the rolling tip frame 2. The operation is simple and intuitive, providing a clear reference for the adjustment of the rolling tip angle.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the upper roll 4 and the lower roll 5 are distributed vertically, and the outer walls of the upper roll 4 and the lower roll 5 are provided with a number of slots circumferentially at equal intervals. The width of the slots gradually decreases from the outside to the inside along the radial direction of the roll. Multiple movable retaining rings 7 are provided and distributed one-to-one along the slots. The movable retaining rings 7 are sleeved on their corresponding slots and can slide along the length of the slot. The movable retaining rings 7 and the fixed side wall at the other end form a relative motion.

[0033] With the above structure, the groove width of the upper roll 4 and the lower roll 5 gradually decreases from the outside to the inside along the radial direction of the rolls, which can realize the progressive shaping of the tipping process and avoid the steel wire from breaking or deforming due to a sudden increase in local stress. At the same time, the movable retaining ring 7 corresponds one-to-one with the groove and can slide along the length of the groove. By changing the distance between the two, the effective width of the groove can be flexibly adjusted, thereby adapting to the tipping processing requirements of steel wires with different diameter specifications. This effectively avoids the need for frequent disassembly due to changes in the diameter specifications of the steel wire, which reduces downtime during roll replacement, reduces the labor intensity of operators, and avoids problems such as decreased accuracy due to repeated disassembly and installation.

[0034] In this embodiment, as Figure 5 As shown, a positioning shaft 401 is fixed inside the upper roller 4. A sliding sleeve 402 is sleeved on the outer wall of the positioning shaft 401. The outer wall of the sliding sleeve 402 is fixedly connected with a push rod group 403 in a ring array. The number of push rod groups 403 corresponds one-to-one with the number of slots where the movable retaining ring 7 is located. Adjacent push rod groups 403 are fixedly connected by a connecting rod 404.

[0035] Through the above structure, the fixed connection between the movable retaining ring 7 and the top rod assembly 403, and the fixed connection between the top rod assembly 403 and the sliding sleeve 402, combined with the cylinder 405 driving the sliding sleeve 402 to slide axially along the positioning shaft 401, form a synchronous linkage adjustment mechanism. The cylinder 405 can drive all the movable retaining rings 7 to slide synchronously along the roll groove, realizing the consistent adjustment of the effective width of the groove and ensuring the uniformity of the wire tip diameter. At the same time, the shaft hole at the roll interval provides precise guiding constraint for the top rod assembly 403, ensuring the stability of the synchronous sliding trajectory of the movable retaining rings 7. This achieves the beneficial effect of being able to quickly adjust according to the diameter specifications, material hardness, and tip forming requirements of the cable conductor wire, responding to the tip diameter requirements of different specifications of steel wire, and improving the processing efficiency and adaptability of the equipment.

[0036] In this embodiment, as Figure 5 As shown, a cylinder 405 is fixed on one side of the outer wall of the mounting frame of the upper roll 4. The sliding sleeve 402 has an extension rod at the center of the shaft at the corresponding end of the cylinder 405. The extension rod passes through the corresponding side of the mounting frame of the upper roll 4 and is rotatably connected to the power output end of the cylinder 405. At the same time, the inner diameter of the rotating shaft at one end of the upper roll 4 used to connect with the mounting frame and the inner diameter of the bearing adapted on the mounting frame are both larger than the outer diameter of the extension rod. The internal structure of the lower roll 5 is the same as the internal structure of the upper roll 4.

[0037] With the above structure, this layout allows the cylinder 405 to remain stationary while the upper roll 4 and lower roll 5 rotate, avoiding problems such as air pipe entanglement and unstable power source caused by the cylinder 405 rotating with the rolls. It also allows the power output of the cylinder 405 to be transmitted to the sliding sleeve 402 through the transmission action of the extension rod, pushing the sliding sleeve 402 to move smoothly axially. The structure that the inner diameter of the upper roll 4 and lower roll 5 shaft and the corresponding bearing is larger than the outer diameter of the extension rod does not affect the rotation of the upper roll 4 and lower roll 5 through bearing installation, and also avoids interference with the installation of the extension rod and the cylinder 405.

[0038] In this embodiment, as Figure 5 As shown, the end of the movable retaining ring 7 facing the top rod assembly 403 is fixedly connected to the end of the top rod assembly 403 at the corresponding position. On the outer wall of the upper roll 4 and the lower roll 5, at the interval end position between two adjacent slots, there are shaft holes for the extension and retraction of the top rod assembly 403. The shaft holes penetrate the interior of the interval end along the radial direction of the roll. The top rod assembly 403 drives the sliding sleeve 402 to slide axially along the outer wall of the positioning shaft 401 through the cylinder 405. Under the drive of the top rod assembly 403, the movable retaining ring 7 can slide along the length direction of the corresponding slot of the upper roll 4 and the lower roll 5.

[0039] Through the above structure, the positioning shaft 401 provides axial sliding restriction and guidance for the sliding sleeve 402, preventing radial displacement of the sliding sleeve 402 during sliding. At the same time, the interior of the upper roll 4 and the lower roll 5 only has the movement range of the components at the corresponding positions of the positioning shaft 401, the sliding sleeve 402, the push rod group 403, etc., to meet the adjustment function requirements, while the remaining areas are designed as solid surfaces. This structure can maximize the preservation of the structural strength and rigidity of the roll while ensuring the realization of the roll's adjustable function, and ensure the stable transmission of the rolling force of the roll to the steel wire.

[0040] In this embodiment, as Figure 3 and Figure 4 As shown, the roll adjustment and drive assembly 6 includes an upper drive bevel gear 601, a lower drive bevel gear 602, a driving bevel gear 603, a driven bevel gear 604, and a screw 607. The upper drive bevel gear 601 and the lower drive bevel gear 602 are coaxially arranged through a sliding cooperating shaft 605. The driving bevel gear 603 and the driven bevel gear 604 are distributed vertically. The driving bevel gear 603 is fixedly connected to the center point of the upper roll 4 at the corresponding end through a shaft passing through its axis. The driven bevel gear 604 is fixedly connected to the center point of the lower roll 5 at the corresponding end through a shaft passing through its axis.

[0041] With the above structure, the upper drive bevel gear 601, the lower drive bevel gear 602 and the sliding coaxial shaft 605 are coaxially arranged, and the driving bevel gear 603, the driven bevel gear 604 and the corresponding rolls are fixedly connected, so that the relative rotation of the upper and lower rolls can be realized, ensuring the power for the tipping process.

[0042] In this embodiment, as Figure 3 and Figure 4 As shown, a hollow shaft 606 is fixed at the center of the upper transmission bevel gear 601, and the upper transmission bevel gear 601 is connected to the bearing set at the corresponding position of the mounting frame where the upper roll 4 is located through the hollow shaft 606. The sliding cooperative shaft 605 passes through the hollow shaft 606, and the outer wall of the sliding cooperative shaft 605 has raised strip-shaped structures symmetrically distributed along the center point. The inner wall of the hollow shaft 606 has a slot adapted to the strip-shaped structure. The strip-shaped structure and the slot are embedded and engaged to realize the synchronous rotation and axial relative sliding between the sliding cooperative shaft 605 and the hollow shaft 606.

[0043] Through the above structure, the embedded interlocking strip structure and slot between the hollow shaft 606 and the sliding cooperating shaft 605 not only achieve synchronous rotation of the two, ensuring stable power transmission to the driving bevel gear 603 and the driven bevel gear 604, and ensuring synchronous relative rotation of the upper roll 4 and the lower roll 5, but also allow the hollow shaft 606 to slide relative to the sliding cooperating shaft 605 axially when the upper roll 4 is adjusted by means of the screw 607, thereby realizing the coordinated action of roll spacing adjustment and rotation drive, which can stably adapt to the tipping processing requirements of steel wires of different specifications.

[0044] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the top of the rolling mill 2 is provided with a threaded groove for threaded connection with the screw 607. The shaft head at the bottom of the screw 607 passes through the threaded groove and is rotatably connected to the top of the mounting frame where the upper roll 4 is located.

[0045] With the above structure, the rolling pin frame 2 is equipped with a guide rod for sliding the upper roll 4 mounting frame. The upper roll 4 mounting frame is raised and lowered by the threaded engagement of the screw 607 and the threaded groove. The rotational connection between its bottom and the mounting frame ensures that the screw 607 will not drive the mounting frame to rotate synchronously when it rotates, and also provides stable support and positioning for the mounting frame. In conjunction with the guide structure inside the mounting frame and the fixed base 1, the accuracy of the linear motion of the upper roll 4 during the raising and lowering process can be further guaranteed.

[0046] The specific operation process of this invention is as follows: When the wire tipping machine is in use, a dedicated tipping reduction motor for driving the adjustment of the rolls and the operation of the drive assembly 6 is installed above the fixed base 1. The operator can adjust the tipping diameter and tipping angle according to the specifications of the steel wire for cable conductors (such as wire diameter and material hardness) and the tipping forming requirements at the cable joint. The specific usage process is as follows: First, for different diameter specifications of cable wire tipping, the distance between the upper roller 4 and the lower roller 5 needs to be adjusted to match the wire diameter.

[0047] During adjustment, the operator rotates the screw 607 above the fixed base 1. Since the mounting bracket for mounting the upper roller 4 is rotatably connected to the bottom of the screw 607, and the mounting bracket is slidably connected to the guide rod inside the fixed base 1, the upper roller 4 will rise and fall vertically with the forward and reverse rotation of the screw 607, thereby widening or narrowing the gap between it and the lower roller 5 until the gap is adapted to the diameter of the steel wire to be processed.

[0048] During this process, since both the upper drive bevel gear 601 and the drive bevel gear 603 are fixedly installed on the mounting frame where the upper roll 4 is located, they will move up and down synchronously with the mounting frame. At the same time, the hollow shaft 606 fixed at the shaft center of the upper drive bevel gear 601 has its inner wall groove and the raised strip structure on the outer wall of the sliding cooperating shaft 605 in an embedded engagement. This structural design allows the hollow shaft 606 to rotate synchronously with the sliding cooperating shaft 605 and slide up and down along the axial direction of the sliding cooperating shaft 605, thereby ensuring that the upper roll 4 and the lower roll 5 always maintain a relative rotational state while adjusting the distance between them.

[0049] Simultaneously, precise control of the tip diameter is ultimately achieved by changing the effective width of the slots on the surfaces of the upper roll 4 and the lower roll 5, which are used to limit the forming range of the wire tip. When adjusting the slot width, the operator starts the equipment power supply, and the cylinder 405 on the other side of the mounting brackets of the upper roll 4 and the lower roll 5 (the two have the same structure and the same adjustment logic) is activated. Its power output end pushes the sliding sleeve 402, which is rotatably connected to it, to slide along the positioning shaft 401 towards the direction of the roll adjustment and drive assembly 6. Due to the top rod assembly 403 and the outer wall of the sliding sleeve 402, The push rods are fixed in a ring array, and the end of each push rod group 403 away from the sliding sleeve 402 is fixedly connected to the corresponding movable retaining ring 7. Therefore, the push rod group 403 will slide axially along the positioning shaft 401 with the sliding sleeve 402, and simultaneously extend and retract in the shaft holes at the corresponding positions of the upper roller 4 and the lower roller 5. This will push the movable retaining ring 7 to slide along the groove length direction on the surface of the upper roller 4 and the lower roller 5, changing the distance between the movable retaining ring 7 and the fixed side wall at the other end of the groove, and finally achieving the adjustment of the effective width of the groove, so as to achieve the purpose of accurately controlling the diameter of the steel wire tip.

[0050] Secondly, to meet the different adaptation requirements of the wire tipping angle during subsequent cable installation and connection, the rolling direction of the rolls needs to be changed by adjusting the angle of the tipping frame 2, thereby controlling the tipping angle of the wire end. During adjustment, the operator first removes the fastening bolts on one side of the fixed base 1 and the tipping frame 2 to release the angle locking state of the two, and then rotates the adjustment handle corresponding to the worm 101 on the outside of the fixed base 1. The worm 101 is driven to rotate around its own axis by the handle. Since the worm 101 meshes with the worm wheel 102, the rotation of the worm 101 will drive the worm wheel 102 to rotate synchronously. The worm wheel 102 is fixedly installed at the bottom of the tipping frame 2. Therefore, the tipping frame 2 will rotate around the shaft that runs through its axis as the worm wheel 102 rotates, thereby realizing the adjustment of the tipping angle.

[0051] During this process, the angle scale plate, which is fixedly connected to one end of the shaft of the worm gear 102, will rotate synchronously with the worm gear 102. The operator can use the pointer on the outer wall of the fixed base 1 to read the specific angle value pointed to by the pointer on the angle scale plate, thereby realizing the visual and precise adjustment of the tip angle. After the angle is adjusted to meet the cable installation requirements, the fastening bolts on one side of the fixed base 1 and the tip frame 2 are tightened again to lock the angle position of the tip frame 2, and then the equipment can be started to perform the tip rolling operation.

[0052] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
