Description

Technical Field

[0001] This utility model relates to the technical field of wire processing equipment, specifically a double-blade wire stripping machine. Background Technology

[0002] In many industrial fields such as electrical, electronic and communication, wires are the core components for the transmission of electrical energy and signals. The precise stripping of their insulation layer is a key step in the wire processing flow, which has a decisive impact on the quality of subsequent wiring, welding and other processes as well as the overall performance of the product.

[0003] Traditional wire stripping methods typically employ either a circular cut or a single straight cut along the conductor's axial direction. However, after a single axial cut, the insulation layer covering the outer surface of the conductor possesses a certain degree of deformation recovery, meaning the cut insulation layer cannot easily separate from the internal core, making subsequent stripping operations extremely difficult.

[0004] On the other hand, traditional ring-cutting methods are mainly suitable for short-distance wire stripping operations at the ends of conductors. When it comes to recycling extremely long scrap conductors, traditional ring-cutting methods cannot meet the stripping requirements, significantly reducing their practicality.

[0005] Therefore, a double-blade wire stripper is proposed. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a double-blade wire stripper, which has the advantages of high efficiency and portability in wire stripping. It solves the problems of difficulty in separating the insulation layer from the wire core after cutting in traditional wire stripping methods, as well as the fact that it is only suitable for stripping short-distance ends and cannot meet the stripping needs of ultra-long waste wire recycling.

[0007] (II) Technical Solution To achieve the aforementioned goal of efficient and portable wire stripping, this utility model provides the following technical solution: A double-blade wire stripper includes a frame, a square frame is clamped on the inner side of the front end of the frame, and two blades are symmetrically arranged at the upper and lower ends of the square frame. The two blades penetrate the square frame and can slide up and down. Their front ends are blade edges, and their opposite ends are located inside the square frame to cut the upper and lower sides of the wire. Each tool is fitted with a limiter, and the two limiters are positioned opposite each other to position the guide wire; The upper and lower inner walls of the square frame are both fixed with electric push rods, and the output end of the electric push rods is used to drive the limiter to move up and down. The frame is equipped with a support plate located at the rear of the square frame. At the end of the frame, there are vertically distributed drive rollers and driven rollers. The drive rollers are fixedly connected to a motor. Cut wires are sandwiched between the drive rollers and the driven rollers.

[0008] The preferred technical solution of this utility model is that the limiter includes a square kit, the square kit has a through hole through which a cutting tool passes, and a number of positioning pieces are radially distributed on both sides of the through hole.

[0009] The preferred technical solution of this utility model is that the distance between two adjacent positioning pieces is the same as the thickness of a single positioning piece, and the upper positioning piece and the lower positioning piece are misaligned and slide together.

[0010] The preferred technical solution of this utility model is that a circular shaft is rolled on the opposing end face of the positioning plates on both sides, the circular shafts on both sides are at a 90° angle and abut against the outer surface of the wire, and the circular shafts can roll along the direction of the moving axis of the wire.

[0011] The preferred technical solution of this utility model is that the cutting tool is fitted with a tool sleeve fixed to the outer surface of a square frame, and the tool sleeve is threaded with a bolt for locking the cutting tool.

[0012] The preferred technical solution of this utility model is that the support plate is further provided with two limiting wheels that can rotate horizontally, and the two limiting wheels are used to guide the cut wire.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a double-blade wire stripper, which has the following beneficial effects: This double-blade wire stripper uses two symmetrically arranged blades to precisely cut the top and bottom sides of the wire, deeply destroying the connection structure between the insulation layer and the wire core. This effectively overcomes the separation problem caused by the deformation and recovery force of the insulation layer, making subsequent wire stripping operations easy and convenient. It greatly improves the efficiency and quality of wire stripping, ensures the stable performance of the wire in subsequent wiring, welding and other processes, reduces the product defect rate, and provides a reliable guarantee for the production process.

[0014] This double-blade wire stripper, through the flexible and adjustable limiters and the cooperation of active and driven rollers, can accurately position wires of different specifications and adapt to complex wire stripping scenarios such as the recycling and processing of extra-long waste wires. The limiters provide precise positioning without damaging the wires, while the active and driven rollers stably transport the wires under the drive of the motor, meeting diverse wire stripping needs, broadening the application range of wire stripping, and improving the practicality and versatility of the equipment.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0020] Please see Figure 1-5 A double-blade wire stripping machine includes a frame 1, a square frame 2 is clamped on the inner side of the front end of the frame 1, and two blades 4 are symmetrically arranged at the upper and lower ends of the square frame 2. The two blades 4 penetrate the square frame 2 and can slide up and down. Their front ends are blade edges, and their opposite ends are located inside the square frame 2 to cut the upper and lower sides of the wire 12. Each tool 4 is fitted with a limiter 5, and the two limiters 5 are arranged opposite each other to position the guide wire 12; Electric push rods 6 are fixed on the upper and lower inner walls of the square frame 2. The output end of the electric push rods 6 is used to drive the limiter 5 to move up and down. The frame 1 is provided with a support plate 3 located behind the square frame 2. The end of the frame 1 is rotatably provided with an upper and lower distributed drive roller 9 and a driven roller 10. The drive roller 9 is fixedly connected to a motor 11. A cut wire 12 is sandwiched between the drive roller 9 and the driven roller 10.

[0021] In this embodiment, the limiter 5 includes a square kit 51, which has a through hole 53 through which the cutter 4 passes, and a number of positioning pieces 52 radially distributed on both sides of the through hole 53.

[0022] It should be noted that this design aims to surround and position the wire 12 from different directions using multiple positioning plates 52, thereby increasing the stability and accuracy of the positioning. The positioning plates 52, which are radially distributed on both sides, can be moved up and down to flexibly adjust the clamping range of the wire 12 according to its specifications, ensuring that the wire 12 will not shift or shake during the stripping process, thus ensuring the accuracy of the cutting position and improving the stripping quality.

[0023] It should be further explained that the difficulty of bidirectional cutting lies in how to ensure the stability of the clamping during cutting. This structure uses a limiter 5 and an open through hole 53 to allow the tool 4 to directly contact the insulation layer of the wire 12 through the through hole 53 for cutting. It is simple to install and highly practical.

[0024] In this embodiment, the distance between two adjacent positioning pieces 52 is the same as the thickness of a single positioning piece 52, and the upper positioning piece 52 and the lower positioning piece 52 are misaligned and slide in a sliding fit.

[0025] It should be noted that the ingenuity of this design lies in the close arrangement of adjacent positioning pieces 52 with the same spacing and thickness, which allows the positioning pieces 52 to form a relatively tight wrapping structure, further enhancing the positioning effect on the wire 12. At the same time, the upper and lower positioning pieces 52 slide in a staggered manner, so that when facing wires 12 of different diameters, the positioning pieces 52 can automatically adjust their positions according to the actual size of the wire 12 under the drive of the electric push rod 6, improving the adaptability and practicality of the limiter 5.

[0026] In this embodiment, a circular shaft 54 ​​is rolled on the opposing end face of the positioning plates 52 on both sides. The circular shafts 54 on both sides are at a 90° angle and abut against the outer surface of the wire 12. The circular shafts 54 can roll along the moving axis of the wire 12.

[0027] The circular shaft 54 ​​reduces friction between the positioning plate 52 and the wire 12. During the wire 12 conveying process, the circular shaft 54 ​​rolls along the axis of the wire 12, making the wire 12 move more smoothly and avoiding wear or conveying difficulties caused by excessive friction. Furthermore, the two circular shafts 54 abut against the wire 12 at a 90° angle, positioning the wire 12 from two vertical directions. This ensures the wire 12 remains stable in the horizontal plane, preventing twisting or shifting during stripping and improving stripping accuracy.

[0028] It should be noted that if a rolling shaft 54 ​​is not added, the positioning accuracy of the limiter 5 may be insufficient, or the clamping may be too tight, causing the wire 12 to be unable to move or to be cut.

[0029] In this embodiment, the cutter 4 is fitted with a cutter sleeve 7 fixed to the outer surface of the square frame 2, and the cutter sleeve 7 is threaded with a bolt 8 for locking the cutter 4.

[0030] It should be noted that the main function of the blade holder 7 is to provide stable support and fix the blade 4 in a fixed position, ensuring that the blade 4 remains straight when sliding up and down to cut the wire 12, without wobbling or shifting, thus guaranteeing consistent cutting accuracy and depth. The bolt 8 is used to lock the blade 4 in place. After adjusting the height of the blade 4, tightening the bolt 8 secures the blade 4 firmly to the blade holder 7, preventing displacement of the blade 4 due to vibration or other reasons during wire stripping, which would affect the stripping effect. This design also facilitates the replacement and maintenance of the blade 4. When the blade 4 wears out or needs to be replaced with a different specification blade 4, simply loosening the bolt 8 allows for easy disassembly and installation.

[0031] In this embodiment, the support plate 3 is also provided with two limiting wheels 13 that can rotate horizontally. The two limiting wheels 13 are used to guide the cut wire 12.

[0032] It should be noted that the limiting wheel 13 is used to guide the insulation layer cut into two parts to the wire cores on both sides and away from the middle of the conductor 12. Since the insulation layer is often unnecessary or discarded during the stripping process, the advantage of designing the limiting wheel 13 is that it can output the insulation layer and the wire core from different output ports, which is convenient for subsequent classification. Another advantage is that when the limiting wheel 13 guides the insulation layer, the two cut insulation layers are at a certain angle. When the motor 11 drives the insulation layer and the wire core to move together, the insulation layer has a certain outward expansion force. This action will promote the separation of the insulation layer and the wire core and improve the separation effect.

[0033] Meanwhile, the setting of the limiting wheel 13 further enhances the stability of the wire 12 during the stripping process. After the wire 12 is conveyed between the driving roller 9 and the driven roller 10, the limiting wheel 13 can limit the wire 12 in the horizontal direction, preventing the wire 12 from shifting laterally during the conveying process and ensuring that the wire 12 always moves along the predetermined path. At the same time, the limiting wheel 13 can rotate horizontally without obstructing the conveying of the wire 12, ensuring the smoothness of the wire 12 conveying and improving the stability and reliability of the entire stripping process.

[0034] In summary, this double-blade wire stripper, through two symmetrically arranged blades 4, precisely cuts the upper and lower sides of the wire 12, deeply destroying the connection structure between the insulation layer and the wire core. This effectively overcomes the separation problem caused by the deformation recovery force of the insulation layer, making subsequent wire stripping operations easy and convenient, greatly improving stripping efficiency and quality, ensuring the stable performance of the wire 12 in subsequent wiring, welding and other processes, reducing product defect rate, and providing reliable assurance for the production process.

[0035] This double-blade wire stripper, through the flexible and adjustable limiter 5, drive roller 9, and driven roller 10, can accurately position wires 12 of different specifications and adapt to complex wire stripping scenarios such as the recycling and processing of extra-long waste wires 12. The limiter 5 provides precise positioning without damaging the wires 12, while the drive roller 9 and driven roller 10 stably transport the wires 12 under the drive of the motor 11, meeting diverse wire stripping needs, broadening the application range of wire stripping, and improving the practicality and versatility of the equipment.

[0036] Working principle: First, pass one end of the wire 12 through the square frame 2 and cut its upper and lower ends with a knife. Divide the insulation layer of the wire 12 that passes through the square frame 2 into two parts, left and right. Then press the insulation layers on both sides between the driving roller 9 and the driven roller 10 through the limiting wheel 13. At the same time, press the wire core between the driving roller 9 and the driven roller 10.

[0037] Then, the electric push rod 6 is activated, causing the two limiters 5 to move towards each other, positioning the wire 12 within the two limiters 5 (the accuracy of the up-and-down movement of the electric push rod 6 will not affect the wire stripping of this device). Then, by pulling the wire 12 on the front side, the separation point of the insulation layer previously cut by the knife is positioned exactly within the limiter 5. Then, the bolt 8 is loosened, and the cutting depth of the upper and lower blades 4 is adjusted. After adjustment, the bolt 8 is rotated to fix the blades 4. Finally, the motor 11 is activated, and the motor 11 drives the wire 12 to move, causing the wire 12 and the blades 4 to move relative to each other, thereby achieving the wire stripping process of the wire 12.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
